Patent Application
20090056258
The present invention relates generally to an apparatus, system and method for forming a material, and more particularly, to an apparatus, system and method for forming a conformable material, such as, for example, concrete.
In the construction industry, numerous techniques, methods, and devices are available for building structures out of a variety of materials using different structural systems. Some construction methods use, for example, “wood frame walls”; others use “concrete block walls.” Many of these structural systems and construction methods, however, require time-consuming, heavy and cumbersome “component-by-component” construction—with relatively difficult to handle components (e.g., boards, concrete blocks, etc.). Moreover, these components must be secured together in some manner (e.g., nails, mortar, etc.) and typically require skilled, experienced labor.
Building a “concrete block wall,” for example, requires specialized masonry skills to properly handle and align blocks and apply mortar to join and secure the concrete blocks so as to form a uniform, vertically and horizontally aligned block wall; such specialized labor adds to the cost and time of a construction project.
In contrast to a “concrete block wall,” a poured concrete wall in many instances produces a stronger, longer-lasting wall, which provides more desirable sound and weather-resistant qualities. A poured concrete wall is effectively one solid structure while a “concrete block wall”—which in effect requires handling each cumbersome concrete block—is constructed, as noted, block-by-block with mortar for example. A solidly constructed poured concrete home would also provide durability and many other advantages typically needed where there is exposure to hurricanes, tornados or other harsh weather conditions. Additionally, unlike a “wood frame wall,” such a structure also is resistant to termites.
Various methods and devices for building concrete walls include, for example, first erecting forms usually consisting of several parallel walls which form a space therebetween for receiving and holding concrete. Such devices also usually require substantial alignment and bracing prior to pouring concrete. Once the poured concrete wall has fully cured, the forms may be removed.
Unfortunately, many of these processes and devices have drawbacks in that they utilize forming walls, complicated shoring reinforcements and alignment devices that are unwieldy, heavy, and require extensive effort and expense to transport to and from a construction site. Due to their weight and bulkiness, many of these form devices require large equipment to handle and position them during the set up and forming process—thus making them time-consuming and cumbersome to use prior to actually being able to pour concrete. Moreover, such hefty and awkward devices leave even fewer options for less-muscle bound individuals or elderly persons with certain ailments who desire—on their own—to set up and handle forms so as to form up some structure, building or the like.
There are also other types of forming systems—which are not reusable and remain permanently affixed to the building. Such systems typically include insulating features and also incorporate insulating materials and multi-layered forms having built in insulation. Unfortunately, these systems may be unnecessarily labor-intensive and may be too complex to efficiently use for many building structures thus driving up the effort and cost of a construction project. And, again, they can require specialized labor or training.
In addition, although some multiple form devices are reusable, these forms are not easily and quickly removable—especially when multiple adjacent forms are interconnected next to and/or stacked on one another using time-consuming, threaded fasteners.
The following U.S. patents disclose a variety of systems and devices, which have attempted to resolve at least some of the above problems:
U.S. Pat. No. 6,405,505 to Alberti, entitled “Modular interlock wall form,” sets forth a modular interlock wall form for providing a sturdy wall structure that is easily assembled and disassembled. The modular interlock wall form includes a base frame for resting on a surface, and which includes a pair of elongate base rails extending in the longitudinal direction of the base frame. The base rails are laterally spaced, and at least one lateral member extends laterally across the base rails. The lateral member has a fascia support portion extending substantially perpendicular to an axis of a central portion of the lateral member. A face panel is provided for forming a face of the modular interlock wall form. The face panel has opposite surfaces and a perimeter edge. The perimeter edge comprises opposite end edges and opposite first and second edges. The first edge is adapted for being oriented downwardly and the second edge is adapted for being oriented upwardly.
The second edge has a tongue extending along the length of the second edge with at least one pocket recessed in the tongue. The first edge has a groove extending along the length of the first edge, and is also adapted to receive one of the base rails of the base frame and is adapted to receive the tongue of the first edge. The end edges also have grooves formed therein. A linking frame is provided for linking spaced tiers of face panels together. The linking frame comprises a pair of linking members extending in the longitudinal direction of the linking frame, and at least one spanning member extending laterally across the linking members. The spanning member is coupled to each of the linking members.
U.S. Pat. No. 6,363,683 to Moore, Jr., entitled “Insulated concrete form,” discloses an insulated concrete structure including at least one longitudinally-extending side panel and at least one web member partially disposed within the side panel. The web member extends from adjacent the external side of the side panel through and out of the interior surface of the side panel. The first embodiment of the present invention uses opposed side panels that form a cavity therebetween into which concrete is poured and cured. The second embodiment uses a single side panel as a form, onto which concrete is poured. Once the concrete cures on the single side panel, it is used as a tilt-up wall, floor, or roof panel.
U.S. Pat. No. 6,321,496 to Martin, Jr., entitled “Insulated form assembly for a poured concrete wall,” is directed to an insulated form assembly for a poured concrete wall which includes a plurality of insulated forms. Each insulated form includes two generally planar opposing panels, and a plurality of interior segments interconnecting the panels and defining a plurality of passageways. Each panel includes a vertically extending attachment channel and an attachment member disposed within the attachment channel.
U.S. Pat. No. 6,178,711 to Laird et al., entitled “Compactly-shipped site-assembled concrete forms for producing variable-width insulated-sidewall fastener-receiving building walls,” sets forth generally large, typically eight feet by two inches by ten or sixteen or twenty-four inches, sidewalls for modular concrete forms which are easily, efficiently and economically produced by cutting and by routing sheet-type polymeric material, preferably polyurethane or expanded polystyrene foam. Metal connecting members are produced in standard sizes by cutting and bending sheet steel and/or wire. The sidewalls and connecting members are transported to a building site tightly and compactly in pieces, and then flexibly assembled into precision wall forms at the site with good efficiency at any scale. The wall forms so assembled define a cavity into which reinforcing steel rod, electrical and/or communications conduit, plumbing, etc., may be entered. Concrete is poured into the cavity to create a wall having the form sidewalls as its permanent surfaces. These surfaces have and present visible regularly-spaced sheet steel strips suitable to receive and to engage sheet metal screws for mounting anything, including more sheet-type construction materials such as wallboard or paneling, to the wall. The thickness of the concrete wall is predetermined by the dimensions of its metal sidewall-connecting members, and may easily be varied such as during the fabrication of lower to upper wall courses of a multi-story building.
U.S. Pat. No. 5,735,093 to Grutsch, Jr., entitled “Concrete formwork with backing plates,” is directed to foam forms for use in making a concrete wall that are disclosed together with a method of making the forms. The forms are stackable to form a cavity that receives the concrete. Each form has two identical panels. The panels are molded separately by first placing a structure, consisting of backing plates that will be along one side of the mold, connecting members that will be along the opposite side of the mold and an apparatus that connects the backing plates to the connecting members, in the mold. The mold is then filled with foam which cures and produces a panel with the backing plates, connecting members and apparatus molded into the panel. The molded panels are then shipped to the job site where the forms are assembled. Each form is assembled as follows: The connecting members on one panel are interconnected, by tieing means, to the connecting members on a second panel to provide a form.
U.S. Pat. No. 4,936,540 to Boeshart, entitled “Tie for concrete forms,” sets forth a tie for concrete forms which includes an elongated strap with opposing first and second ends. The strap has an upwardly projecting intermediate portion which prevents the movement of form panels inwardly on one end of the strap. A notch in the first end of the strap receives a waler to hold form panel from moving outwardly along the strap. A fixed plate on the second end of the strap holds a form panel from moving outwardly along the strap. Beveled ends allow the strap to be forced through a polystyrene panel without the need for forming an aperture in the panel prior to insertion of the tie. A tubular spacer may be utilized on intermittent ties to prevent inward movement of the form panels. The spacer has a notch cut therein to allow concrete to flow within the spacer and around the tie.
U.S. Pat. No. 4,726,560 to Dotson, entitled “Concrete form tie assembly,” sets forth a concrete form tie assembly in which the tie rod is formed from a high tensile strength flexible wire member, with the sleeve being formed of a flexible or yieldable material. A short sleeve member is inserted into the spacer sleeve adjacent one end with washer members on opposite ends thereof for retaining on the tie rod member which is provided with spaced protrusions for coaction with the wash members, the tube and washer assembly serving to rigidify the assembly for assisting in insertion and removal of the tie rod and sleeve as a unit. The leading end of the tube and washer assembly may be provided with a conical end to act as a guide. The ends of the tie rod member are enlarged, such as by welding head members thereto, the head members being configured for coaction with conventional hairpin or snap tie wedge members.
U.S. Pat. No. 3,927,857 to Lovisa et al., entitled “Reusable tie assembly for concrete forms,” discloses a retractable, removable and reusable tie assembly for concrete forms which includes a single tie rod having a pipe slidably mounted on one end thereof and an internal spreader system interposed between its ends for spacing the forms a predetermined distance apart during concrete pour. The internal spreader system includes a loose cone adapted to be threadedly engaged with one end of the pipe and a rubber tube adapted to sealingly engage with this cone as well as a second cone secured to the other end of the tube. This connection includes a ferrule and insert engageable with a steel washer embedded in the secured cone. The insert is interiorly threaded to facilitate removal of the cone and attached rubber tube after the forms have been stripped. Interengaging surfaces of threaded insert and the rod assure the proper location of the internal spreader system after the first and closing form have been erected. Wedges at each end of the tie assembly complete the erection of the forms. After the concrete has been formed and satisfactorily hardened the forms are then stripped. Towards this end, the rod and associated pipe are removed by initially uncoupling one or both of the wedges and then unscrewing the pipe from its associated cone. Thereafter the loose cone may be removed with a suitable tool or bolt with a thread mating with the internal thread of this cone. The other cone and secured tube may then be removed by means of a second tool or bolt having a threaded portion mating with that of the thread of the insert. The tie assembly may then be reused where desired.
U.S. Pat. No. 3,858,993 to Lovisa et al., entitled “Reusable tie assembly for concrete forms,” is directed to a retractable, removable and reusable tie assembly for concrete forms which includes a single tie rod, and an internal spreader and spacing system which includes a sleeve means, the spreader system having built-in provisions for internal spreading and spacing of forms in such a manner as to permit the tie rod to be partially withdrawn on one side of the form facilitating the installation of the closing form, on the opposite side, and then to be inserted to engage and lock with the internal spreader system, thus keeping the two adjacent sides of the forms in a definite predetermined position apart during the concrete pour, then to be removed undamaged from the hardened concrete prior to dismantling of the forms, leaving the internal spreader in the concrete to be removed after stripping of the forms without damaging the internal spreader.

However, in view of the foregoing, there still remains a need for a forming system, method and apparatus including a simple-to-manufacture, configurable forming member which is easy to set up, stack, and remove after the concrete wall is poured and has cured and which has a simple, reusable configuration which is adapted to be more easily and quickly installed, without requiring specialized and experienced skilled labor, so as to enable a person without such specialized training or education to form and build a wall.
Those of skill in the art will appreciate the present invention which addresses the above problems and other significant problems, the solutions to which are discussed hereinafter.
It is one possible objective of one possible embodiment of the present invention to provide an improved method and apparatus for forming and retaining a material such as for example, concrete, to build various structures or for forming other materials.
These and other objectives, features, and advantages of embodiments of the present invention will become apparent from the drawings, the descriptions given herein, and the appended claims. However, it will be understood that the above-noted objectives of various embodiments are intended only as an aid in understanding aspects of the embodiments, and are not intended to limit the embodiments of the invention in any way, and therefore do not form a comprehensive or restrictive list of objectives, and/or features, and/or advantages of the various embodiments of the invention.
Accordingly, in one possible embodiment, an apparatus is provided for retaining a conformable material, including at least a forming member comprising at least two panels connected in spaced relation so as to define a passageway adapted to retain a first supply of conformable material which hardens in place, such as, in one embodiment, concrete. Each of the at least two panels of the forming member further preferably comprises at least one interconnectable end defining an interconnectable element. The at least one interconnectable end, in some embodiments, forms an interengageable slot with the interconnectable element adapted to be interconnectable with at least one other structure. The one other structure in a preferred embodiment comprises one or more forming members being configured similarly. Additionally, the at least two panels, in one embodiment, are adapted to be disconnectable after use to subsequently receive a second supply of conformable material, which hardens in place.
Another possible embodiment further comprises an engagement member forming an interconnection slot. The engagement member is preferably receivable by both an interengageable slot of an interconnectable element of a given forming member and an interengageable slot of an interconnectable element of at least one other forming member, wherein the given forming member and the at least one other forming member may be interconnected.
In a possible embodiment, a plurality of forming members are selectively configurable and interconnectable in a desired arrangement such that at least a portion of an enclosure may be constructed from the forming members with the forming members defining a plurality of passageways for retaining the conformable material.
In another possible embodiment, each of the at least two panels further comprises a base flange and a support member. In one embodiment, each of the support members of a given forming member cooperate to alignably receive the base flanges of the at least one other forming member when stacked on the given forming member. In this way, a plurality of stacked forming members would define a wall of forming members defining a plurality of vertically-extending passageways to retain the conformable material. In another embodiment, each of the support members further includes at least a support flange and a guide flange. The guide flanges of the support members are preferably disposed in opposing spaced relation.
In other embodiments, at least two panels are configured so as to define a passageway having a substantially ninety-degree configuration adapted to retain a conformable material. While in various other embodiments, at least three panels are configured so as to define a passageway having a substantially T-shaped configuration adapted for retaining a conformable material.
Another embodiment further comprises a contour member being mountable within the passageway with the contour member having a selected surface contour facing the interior of the passageway.
In another possible embodiment, a forming system is provided for retaining a material with the forming system including at least a forming member comprising at least two panels in spaced relation so as to define a passageway adapted to retain a first supply of settable material. Each of the at feast two panels further comprises a base flange extending from each panel away from the passageway, and a support member on an opposite side from the base flange, with the support member extending away from the passageway. The support member further comprises a guide member adapted to alignably receive a base flange of another forming member when stacked on the forming member. In this way, the at least two panels are alignable with at least two panels of said another forming panel. The at least two panels are preferably, in some embodiments, adapted to be disconnectable after retaining the first supply of settable material for subsequently receiving a second supply of settable material. In one possible embodiment, the each of the at least two panels comprises at least one interconnectable end defining a securable flange with the securable flange adapted to be interconnectable with a corresponding securable flange of another forming member. The forming system preferably comprises, in some embodiment, an engagement component adapted to interconnect a securable flange of the forming member, with a corresponding securable flange of another forming member. In other embodiments, each of the at least two panels further comprises at least one interconnectable end defining an interconnectable element forming an interengageable slot, with the interconnectable element adapted to be interconnectable with at least one other forming member. In such an embodiment, the forming system further comprises an engagement member forming an interconnection slot, with the engagement member receivable by both an interengageable slot of an interconnectable element of a given forming member and an interengageable slot of an interconnectable element of the at least one other forming member. In this way, the given forming member and the at least one other forming member may be interconnected. Moreover, a plurality of forming members having selected configurations may be interconnected and stacked, and a plurality of walls of forming members may be interconnected so as to form at least a portion of an enclosure. In other embodiments, the forming system also further comprising at least one spacer connector comprising a spacer element and a reusable connector, with the at least one spacer connector adapted to releaseably connect in spaced relation each of the at least two panels of at least one of the forming members. In another embodiment, the at least two panels may be configured so as to define a passageway having a substantially non-linear configuration adapted for retaining a settable material. In other embodiments, at least three panels may be configured so as to define a passageway having a substantially T-shaped configuration adapted for retaining a settable material.
In another possible embodiment, a unitary structure reusably combinable with other unitary structures to create forms to receive settable material may be provided, which includes at least a panel, at least one integrally formed interconnectable end defining a securable element, a base flange integrally formed at a first peripheral edge of the panel, and a support member integrally formed at a second peripheral edge of the panel. Preferably, the panel, at least one integrally formed interconnectable end, base flange, and support member are of one-piece construction and comprise at least one of sheet metal or plastic.
For a further understanding of the nature and objects of various embodiments of the present invention, reference should be had to the following detailed description, taken in conjunction with the accompanying drawings, and wherein:
While the present invention will be described in connection with various example embodiments, it will be understood that it is not intended to limit the invention to those embodiments. On the contrary, it is intended to cover all alternatives, modifications, and equivalents included within the spirit of the invention.
One possible preferred embodiment of the present invention effectively provides a system of easy to manufacture reusable forming members that can be used by a person (with or without specialized skills) to inexpensively and quickly build, for example, a concrete building or structure of various desired dimensions using locally available persons and materials. The system is especially ideal for use in regions or countries where there is a lack of skilled construction workers and a need for housing.
The same set of relatively inexpensive forms can be used—and reused—to build many types of houses or buildings having a variety of layouts and designs. The system is also ideal for implementing the “do-it-yourself” projects of homeowners, landowners, and the like who have some time, but little actual construction experience, and who wish to save money while effectively and quickly building a desired structure, building, shed, retaining wall, footing, or the like—or tying into or replacing an existing wooden wall or other structure. A possible embodiment of the present invention may comprise quite lightweight forming members which are easy to set up, stack, remove, and reuse after a concrete wall has been poured and has cured.
Now referring to all of the drawings, and more particularly to
If concrete is not available, then locally available materials such as mud, straw, shells, and the like may also be utilized. Other materials such as foam plastic, other fluid substances or any pourable medium may be utilized. Rebar or reinforcement wires or fibers may also be easily inserted into the pourable medium, or prior to pouring, as will be explained further.
Moreover, in view of the above, it should be noted, that the forming member and system is also modular, compactable, and portable—as well as selectively configurable—so as to be used for less heavy-duty applications and adapted, for example, to selectively create, design and form up a playhouse, fort, dollhouse, theater prop or other such structure using a light-weight, conformable material such as a suitable cellular foam material or the like (which could be readily poured—or blown—into the selectively formed up passageways).
In a possible embodiment, panel 12, as shown in
In the same way, panel 14 may also include two interconnectable ends 30, 32. Each interconnectable end 30, 32 may also define an interconnectable flange or other element 34, 36, and each of the interconnectable elements 34, 36, in one example embodiment, may, for instance, define, form, and/or comprise an interengageable slot 38, 40, respectively. Thus, for example, each interconnectable element 22, 34 (at end 180 of forming member 10) and/or interconnectable element 24, 36 (at end 182 of forming member 10) may be adapted to be interconnectable with at least one other structure.
The modular forming member 10, shown in a “non-interconnected” mode in
In one possible embodiment, each of the at least two panels 12,14 may further comprise at least one interconnectable end defining an interconnectable or other securable element forming an interengageable slot. The interconnectable or other securable element may preferably be adapted to be interconnectable with at least one other structure. For example, in one embodiment, each end (e.g., 180, 182) of forming member 10 could be connected to another forming member defining a passageway having a substantially linear configuration similar to forming member 10 as shown in
It will also be appreciated that in one example embodiment, the at least two panels are adapted to be disconnectable after use. With such a configuration, the at least two panels (e.g., panels 12, 14) may be adapted to be disconnectable after use to subsequently receive a second supply of conformable material, for example, which hardens in place.
Each of the panels, interconnectable ends and interconnectable elements is preferably formed from metal or plastic but may be made of any other suitable material having desired properties and characteristics such as for example, sufficient strength and rigidity to withstand shoring or other forces imparted by any of a variety of materials being retained and formed by the forming member (e.g., to prevent possible bulging of the panels).
Referring still to
Referring now to
As can be seen, each multi-function spacer element 46, 48 serves, in one aspect, to separate and space apart sides 12, 14 such that passageway 16 therebetween has a desired width (i.e. the distance between sides 12,14). This desired width may vary depending on the application and may be established by the selected length of a spacer element. For example, spacer element 46, shown in
It should also be recognized that the connector may be any one of various types of reusable, temporary, and/or permanent connectors or fasteners. For example, forming member 10, in some embodiments, could be permanently connected in an “assembled” mode.
As illustrated in
A spacer connector may be installed, in one possible embodiment, by first positioning a spacer element between the unconnected panels 12, 14 shown in
As noted, the spacing between the panels generally depends on the desired thickness of the resulting formed wall. If a builder desires, for example, to pour a concrete wall having the actual width of a 2×4 (e.g., about 3½ inches), the builder may use a spacer element having substantially the same width as a 2×4. Of course, a spacer element could be selectively sized to space the panels apart at any desired width (e.g., 2×6, 2×8, 4 inches, 8 inches, etc.).
In one possible embodiment, prior to assembly of the forming member 10 (already shown assembled in
It should be noted that if only one spacer connector is desired for use with a forming member, any other unused apertures in the panels can be plugged or sealed. Moreover, the panels can also be configured with only one aperture each and positioned as desired. In other embodiments, a forming member may be configured with no apertures and not held in spaced relation by a spacer connector—but instead by securing the interconnectable ends to another structure (or to adjacent forming members as will be explained further hereinafter).
Turning again to
Forming member 78 is preferably interconnectable with forming member 10 at one end, by engagement member 68, forming an interconnection slot 70, and is interconnectable to forming member 218, at the other end, by similarly configured engagement member 81 (see
To further illustrate an interconnectable feature of the forming system and member using an engagement member, another possible embodiment of the present invention is shown in
Referring again to
For example, an engagement member, in one embodiment shown in
It will be appreciated that in one embodiment, the un-slotted depth Ed, of the engagement member 68 is at least substantially equivalent to the slot depth as denoted by Sd of slot 38 of interconnectable element 34 (as shown in
Likewise, the engagement member (shown in
It should also be noted that, in one embodiment, the engagement member (with the slot width denoted by Es) is adapted to be received by both of the interconnectable ends of immediately adjacent forming members (e.g., see
The interconnection slots of engagement members and the interengageable slots and interconnectable elements and ends of the forming members, in various embodiments, may be suitably sized and shaped to provide a snug or loose interconnection. Also, the engagement member and interengageable slots may be configured for frictional engagement to reduce the possibility of the engagement member disengaging or any undesirable disconnection between the ends of adjacent forming members. In one embodiment, for example, when using the forming system to form out a concrete wall, preferably in most instances, a substantially snug fit will be desired between adjacent forming members so as to avoid unwanted leakage through the seams between adjacent forming members. However, when using the forming system for less viscous materials, a looser fit may be suitable. In addition, in some situations (while retaining and forming certain materials), controlled seepage through the upper and lower portions of the seams between adjacent forming members may be desirable to promote and foster, for example, more uniform curing. Also, a sealer could be used along lateral and longitudinal seams between forming members to minimize leakage (and also to minimize resulting seams in the hardened wall; however, seams may also be shaved off as desired).
In view of the foregoing, an interconnectable (or securable) element of a “first” forming member may be disposed immediately adjacent an interconnectable (or securable) element of a “second” forming member. An engagement member forming an interconnection slot may be further included with the engagement member receivable by both an interengageable slot of a securable member of the “first” forming member and an interengageable slot of a securable element of the “second” forming member. In this way, the “first” and “second” forming members may be interconnected. Moreover, a plurality of forming members may be simply and easily interconnected next to one another so as to form a plurality of longitudinally extending passageways in communication with one another.
Turning again collectively to
The support members 96, 100 (see
In this way, each of the support members of a given forming member may be preferably configured and oriented in opposing relation so as to alignably receive each complementary base flange of another forming member. Such a self-alignment feature fosters easy and simple stacking of forming members and aids in building a more plumb form wall.
In view of the foregoing, it can be seen in
It should be noted, however, that with the flexible and configurable design features of the panels 12, 14, the panels shown in
Turning again to
A support member is preferably integrally formed with its respective panel so as to foster ease of manufacture and to strengthen the panel. However, a given support member can be further strengthened and/or disposed, or for example, connected to the top edge of its respective panel in any of various ways such as by welding, bracketing, bracing, riveting, adhering, or by other reinforcing or connection systems. In addition, if further reinforcement is desired, one or more vertically or otherwise oriented rib structure(s) could be connected between each support member and base flange of a panel and/or one or more horizontally or otherwise oriented spar structure(s) could be connected between each interconnectable end of a panel.
In one possible embodiment, each of the support members 96, 100 of the panels 12, 14 further comprises a support flange 108, 112 and a guide flange or guide member 110, 114, respectively. The guide flanges or members 110, 114 are preferably disposed in opposing spaced relation and are preferably oriented, at least in one embodiment, substantially orthogonal to the support flanges. In this way, opposing guide flanges of a given forming member are in functional cooperation with each other to reinforceably secure the base flanges of another forming member stacked thereon. In effect, the guide flanges may serve as alignment flanges. (For example, see
In another possible embodiment of the present invention, each of the at least two panels (e.g., 12, 14) further comprises a base flange which is extending from each panel away from a passageway of the forming member, and a support member on an opposite side from the base flange with the support member extending away from the passageway. In such an embodiment, the support member further comprises a guide member adapted to alignably receive a base flange of another forming member when stacked on the forming member. In this way, the at least two panels are alignable with at least two panels of another forming panel.
In addition, it will be appreciated that the engagement member also has design features interoperable with the design features of the multi-purpose interconnectable ends and support members. In one example embodiment, as shown in
As illustrated in
As best shown in both
In another example embodiment, at least one aperture is formed in each base flange and at least one complementary aperture is formed in each support member. In a possible embodiment, as shown in
In addition, the “multi-purpose” base flange, in one possible embodiment, also provides a stabilizing function. That is, with the base flange flared out or extending preferably substantially perpendicular with respect to the plane of its respective panel—and away from the passageway—the base flange serves as a platform-like structure to stabilize the forming member. Of course, the base flange may also be selectively widened (as well as the complementary support member(s)) to provide further stability. In addition, a forming member can be further stabilized by using the apertures of the base flange with a connector (e.g., nail, spike, connector, fastener, etc.) or the like inserted through the aperture to anchor the base flange to a surface—or another forming member.
It should also be recognized that various features of the versatile forming system may be selectively configured and dimensioned such that various components operate together to prevent shoring and misalignment when a plurality of interconnected and stacked forming members are being used. For example, the spacer can be enlarged, thickened, reinforced, and/or strengthened to maintain the inner configuration, alignment, and “conformation” of vertically- and horizontally-extending passageways created by a formed up wall of interconnected and stacked forming members.
In this way, the forming members are adapted to retain and keep concrete or cement for example, in a uniform thickness and height within the passageways—and thus produce a straight wall, vertically and horizontally. It should be appreciated, that with the configuration of the forming members, the forming members may be stacked directly on one another, or staggered such that any seam that might appear on the wall would also have a staggered, block wall-type appearance.
In addition, the spacer elements could also include one or more recesses and/or one or more protuberances, outwardly extending lugs, or other features to aid in more firmly tying rebar or the like in a vertical or horizontal manner to aid or to facilitate securing the formed up wall to a foundation, footing, roofing member or some anchoring structure. The spacer elements also may define a groove, aperture, or eyelet sized to complementarily receive rebar securely (with or without tying) in such a way as to provide further reinforcing strength to the formed wall. For example rebar may have a diameter of about one quarter inch or other dimension as required for desired reinforcement characteristics depending on the resulting thickness of, in one embodiment, a concrete wall and the engineering design specifications. The spacer element groove could be sized accordingly.
The outer surface of the elements or other passageway structures as noted herein may also be textured, coated or treated so as to promote and/or inhibit bonding or the like between such structures and a conformable or settable material (e.g., concrete, etc.). Also, the panels interconnectable ends and/or elements, support members and/or spacer connectors may be formed from a durable, heavier gauge metal depending on the use. For example, the panels may be made from galvanized steel sheets, aluminum, copper, tin, or various other metals depending on the application.
In view of the foregoing, the forming system effectively provides various interoperable and functionally cooperative reinforcing features, as well as others as noted herein, which foster more snuggly securing together an entire wall or enclosure of interconnected and stacked forming members (e.g., see

Also, as shown in
When forming up a “footing” for a wall for example, in one embodiment, any of the various apertures (e.g., 426, 428, 429, 430, 432, 434, 436, 438) of the interconnectable ends, may be used with a fastener to secure one end of a forming member to another. That is, for a formed up footing, or for the bottom row of forming members of a formed up wall (e.g., see 10, 78, 218 in
Likewise, apertures (e.g., 435, 437, 439, 441) of the base flanges (e.g., 394, 398) may be used to anchor the forming members to the ground, foundation, sidewalk, flooring or some platform-like structure (or even a wall in some instances).
Moreover, it will be appreciated, that a footing for a retaining wall or the like could also be formed up and poured first before a retaining wall is formed up. The footing could be formed up by using a plurality of forming members that are wider than the width (in one embodiment as denoted by Pw in
With any type of forming system, it should be noted that a builder must ensure that needed bracing and supports are used as well as a proper base for the formed up wall before and after pouring a material such as, for example, concrete. Another consideration, however, is to not stack the forming members too high so as to create excessive pressure on lower rows of forming members to be filled with concrete. Instead, just the lower rows or levels could be filled with concrete first. After the concrete cures, then, successively higher rows can be filled and cured in stages as needed.
Referring now to
The various components of the panel could also be connected together in various ways. For example, each of the interconnectable ends and/or elements could be connected to a respective panel by any of a variety of methods, such as welding, hinging, fastening (riveting, threaded fasteners, removable or permanent connectors, etc.)
It will also be appreciated that the forming member has a modular, portable configuration. The forming member could be constructed from only two unitary structures or integrated panels and at least one type of one spacer connector. Such a configuration would foster ease of assembly or disassembly as well as handling, transporting, and storage of the forming member(s).
Referring now to
The at least one integrally formed interconnectable end, in one embodiment, or preferably each of two integrally formed interconnectable ends, could also define an interconnectable element forming an interengageable slot with its respective interconnectable end integrally formed at a peripheral end of the panel.
The panel, the at least one integrally formed interconnectable end, base flange, and support member are preferably of a one-piece construction and comprise at least one of sheet metal or plastic. The spacer connector components may also be made from metals, plastics or other materials as noted herein. Also, the panels, interconnectable ends and/or elements, support members and/or spacer connectors may be formed from a durable, heavier gauge metal depending on the use. For example, the panels may be made from steel or galvanized steel sheets or aluminum as well as other metals (copper, tin, etc.). However, various other suitable materials, known to one of ordinary skill in the art, for forming applications could be used as well. Each panel may have a certain gauge wall thickness suitable for retaining and forming heavier or less viscous materials. On the other hand, each panel may have a lesser gauge wall thickness for retaining and forming lighter or more viscous materials. For example, forming members used for concrete may have a wall thickness, in one possible embodiment, in the range of 1/16 of an inch to ⅛ of an inch. In another possible embodiment, the wall thickness may be in the range of ⅛ of an inch to ¼ of an inch; in other embodiments the wall thickness of the various forming member components and structures may vary depending on the application. One possible material may be a steel sheet metal or aluminum; others will be explained further hereinafter.
In manufacture, the unitary structure could be formed with a press or other suitable machinery to form substantially orthogonal bends along peripheral edges of the panel 462 (e.g. 470, 474, 476, 478, 480) to form a unitary member as shown in for example, in
It should also be recognized, that the same unitary structure 460 may be manufactured and used interchangeably for either side of the forming member; thus, a forming member could be manufactured from only two unique components: the unitary member and the spacer connector (comprising the spacer element and connector) and the entire forming member could be constructed from only two unitary members and one or two spacer connectors.
In addition, such a unitary structure and/or separable portions thereof (e.g., as described with respect to forming member 10, 172, etc.)—as well as the entire forming member—could be made from wood, fiberglass, or molded from plastic using injection molding or other suitable manufacturing processes. In some embodiments for certain applications, various structures of the forming member may be formed from high-density polyethylene, polypropylene or other suitable polymers or materials which satisfy desired strength requirements. At least some of the forming member may also be manufactured from various composite materials to make the forming member suitably lightweight and durable for various uses in the construction industry or for various applications in other technology areas or industries.
It will be appreciated, that with such a unitary, modular, and compactable configuration as noted herein, a plurality of forming members—in a “disassembled” mode—can be more efficiently and easily transported to a construction site. Once at the site, the forming members can then be assembled using whatever sized spacer connector lengths are needed for a desired wall thickness and the forming system can be easily installed on site. On the other hand, in view of the portability of the forming members, they can also be pre-assembled at a factory, and, if needed, be easily stacked in certain pre-determined formed up wall dimensions for shipment.
It should also be emphasized, that the weight and portability of the forming system provide many advantages compared to various other systems. With a lighter-weight configuration in use, the forming members could be easily lifted and stacked and/or interconnected. In addition, the forming member panels and spacer connectors are easy to store and would generally take up little space, comparatively, because the panels could be nested and stacked in a disassembled mode. Thus, many thousands of such “nestable” panels and spacer connectors could be manufactured and stored in inventory without requiring substantial space. Moreover, even in an “assembled” mode, a wall of portably and compactly configured forming members, could be stacked and conveniently kept in a storage facility.
In view of the foregoing, the simplicity and efficiency of the forming system can be appreciated. Exemplary embodiments of the present invention include various configurable features of a forming system fostering effective and versatile construction and a quick and easy method for manufacture and assembly of a plurality of forming members. In addition, the cost per individual form would be selectively variable and controllable depending on, for example, the manufacturing costs and the material used.
In effect, the modularity, flexibility, simplicity, and versatility of the forming members provides a selectively arrangeable forming system having features that foster a variety of designs, shapes and arrangements depending on what type of building, shed, containment wall, footing, garage, room, house (exterior walls, or interior walls) or other structure is being formed up and what type of material is being used. In addition, the forming member can be secured to existing building structures and for example, used to tie into and/or replace existing wood or other walls.

Forming member 172 preferably further comprises spacer connectors (not shown in
The panels 174, 176 in one embodiment, also preferably comprise base flanges 204A, 204B, 206A, 206B and support members 208A, 208B, 210A, 210B, respectively with the support members being adapted to alignably receive the base flanges of another complementarily configured ninety-degree forming member (or corner) (or other stackable forming member 10, 310, etc.) being stacked on the forming member 172. Forming member 172 further preferably comprises interconnectable ends and elements similar to, in one embodiment, forming member 10, which are connectable with an engagement member. Also, forming member 172 could form any apertures as described above with respect to forming member 10 (and/or 310, etc.) as needed.
It should also be recognized that a forming member could define a passageway having any of a variety of substantially non-linear (or linear) configurations such as noted above, or for example, having a curved, arched, rounded, zigzagged, V-shaped, U-shaped, or other non-linear configuration, or any other shaped configuration suitable to form a passageway for receiving a material which is preferably conformable. The forming member could also have an X-shaped, T-shaped (as will be explained hereinafter) configuration and the forming system could include any of various combinations or arrangements of substantially linear and/or non-linear forming members or forming members having other configurations.
In addition, in view of the flexible configuration of the forming member, two or more panels (as well as the interconnectable ends) could be parallel or be selectively disposed at angles (laterally or longitudinally, or vertically or horizontally), or, for example, inclined with respect to each other, such that a passageway would have a wedge-shaped, trapezoidal cross-section, or other oriented configurations (e.g., as viewed from the top or an end of a forming member) (or at converging or diverging angles maintained with various spacer connector lengths), as desired along the span of a formed up wall. Of course, the panels of adjacent forming members would be oriented and configured such that the interconnectable ends, support members and/or base flanges had a complementary fit with other adjacent forming members as needed. In this way, forming members could be configured with various opposing panels at selected angles, or with interconnectable curved panels (e.g., intermittently located in a formed up wall as desired, perhaps with an inner panel being planar and an outer panel being curved—such that a poured concrete wall would have a selectively curved outer surface) or other geometrical patterns to as to define a passageway having any of a number of selected configurations or arrangements for various applications, design uses or aesthetic appeal.

End forming member 260 further preferably comprises a pair of interconnectable ends and elements similar to, in one embodiment, forming member 10 (or 172, 310, etc.) which are connectable with an engagement member. Also, end forming member 260 could also form various apertures as described above with respect to forming member 10 (and/or 310, etc.) as needed.

It should be noted that the formed up wall may include many interconnected and stacked forming members (e.g., shown in part in
Referring now to
The support element 299 is, in some embodiments, preferably secured by the fastener element immediately adjacent the inner surface of a formed wall. In this way, the support element, in one embodiment, can be used inside a structure (such as, for example, an interior room, garage or other enclosure or wall) to support some interior object 293 (such as for example shelving, flooring, etc.). The support element 299 is preferably configured so as to form an aperture 299A through which a portion of the support connector 295 (such as for example, the shaft of a bolt or other connector (or part of fastener element 298)) may be inserted. In addition, the head 287 of the connector 295 could also be rounded-off or substantially flush-mounted, in some embodiments, with respect to surface 291 as desired.
It should be noted that a support connector could also be configured for use with a forming member. That is, the support element could be adapted to be secured adjacent to an interior surface of a forming member panel to support an object or forming object (see
Also, in one embodiment, after the panels are disconnected from the cured and formed wall of concrete, any aperture or opening in the formed concrete wall (or a selectively configured support element) may be used to attach a support member adapted to secure bricks, siding, paneling, insulation or insulating systems or some decorative or functional wall surface to the formed concrete wall. Openings could also be selectively sized with a spacer element (in some embodiments, with the spacer element being removable) and be selectively located such that wiring, plumbing, conduit, piping, other building systems or components or the like could be disposed through the opening to provide a passageway or means for locating, installing, or passing such building components from the outside to the inside of a formed structure such as a concrete shed, garage, or other building structure. In addition, if the apertures are not used, they may be sealed with suitable sealers, plugged or filled with suitable material.

For example, in
A contour member may have any number of a variety of surface patterns, reliefs, or other configurations. For example, as shown in
With the design flexibility and configurability of the forming system, a variety of forming members having substantially linear and non-linear configurations (with inner and/or outer panels having any of a number of design and visual features) could be interconnected to form up a wall having various designs, shapes, outer and inner wall surface contours, and dimensions.
In view of the foregoing, it should be noted that, the various interconnecting, stacking, and other cooperative and interrelations features of the substantially linear and/or non-linear forming members provides a forming system and method and apparatus such that a plurality of forming members are selectively configurable and interconnectable in any of many desired arrangements. As such, at least a portion of an enclosure (e.g., a shed, garage, wall (e.g., see
In use, the number of forming members, end panels, and other forming structures to be made ready for a particular project will generally depend on a pre-determined construction plan or blueprint or other building or structural layout. Typically, the dimensions of the building, wall or structure will determine the number of forming members needed for the project. Each of preferably a plurality of forming members and/or panels (e.g., linear and/or non-linear forming members, end forming members and/or end panels, etc., as needed) may be assembled in a similar manner as that described herein (e.g., as explained for each of the forming members, panels and structures with respect to
For example, a linear forming member similar to forming member 10 (and other forming members), in one embodiment, is preferably assembled using a desired selected spacer connector—which has a variable-length feature. That is, a spacer connector can be used which has a spacer element and connector having a selected length depending on the desired “finished” wall thickness (which should be indicated in, for example, a building plan). As an example, the panels 12, 14 of forming member 10 are preferably assembled and secured together with the selected spacer connector in the manner as described above with respect to
In one embodiment of a method, initially the base or ground level forming members are placed first—with additional layers stacked thereafter. Corner-shaped forming members (e.g., like forming member 172 in
For example, with a forming member (e.g., 10) preferably positioned on a desired surface which is preferably flat and level, another forming member (e.g., such as forming member 78, see
Preferably, the entire perimeter of forming members creating the base or ground level is laid out and interconnected, in one embodiment, with engagement members (e.g. 68, etc. in
The perimeter of forming members is preferably leveled, squared up and made plumb as needed, by checking the horizontal and vertical alignment and positioning using a common level tool or certain conventional leveling equipment, shims or other systems and devices. Although it is preferable that the forming members be interconnected and stacked in a level row, the forming members may not be level in certain situations. In such instances, sometimes the fluidity of a poured conformable material such as, for example, concrete will generally level itself within the formed up wall (which effectively forms a plurality of passageways or channels in communication with one another).
In one embodiment, for example referring to
In some structures, it is at the base level that interior forming objects and the like are placed in the passageways (inside the forming members). That is, as explained before, form objects (form boards, boxes, pipes, etc.) may be installed within the passageways to create voids for window or doorway openings, holes for piping or plumbing (e.g., at the base or ground level) or other cavities. Forming objects for windows are placed at the level needed when forming up a wall.
Also, the formed up wall may be reinforced using steel rods or rebar or other structural reinforcements. Rebar, for example, may be positioned and oriented as desired (horizontally, vertically, diagonally, etc.) within the passageways or channels and tied or wired to spacer elements or just, in some appropriate instances, positioned in place as desired. Reinforcing structures secured vertically aid in joining each level of forming members and keeping the forming member rigid and in place. Bracing structures (e.g., boards, tension wires, cables, etc.) may also be installed or secured as needed. Moreover, other structures, connectors (e.g., such as J-anchors, anchor bolts, etc.) or the like, may be used in some instances (e.g., on top form rows) to attach, tie in or anchor a roof to a wall (or to tie a wall to an existing wall) or the like. The base (or ground) level may then receive concrete, or additional forming members may be stacked in the same conformity as the base level as noted herein. This process may be continued to the desired height of the wall. With this configuration, concrete may be poured in a one-pour process (or level-by-level as will be explained further.) (It should be noted that sometimes it might also be desirable to appropriately—and very carefully—vibrate or agitate the wet concrete to cause it to fill voids and flow more evenly throughout the passageway).
After the wall has been completely poured and has cured, the forming members and forming objects may be removed and the desired openings for windows, doors, plumbing, etc., will remain. Also, after removing the connectors and panels, the spacer elements will remain leaving openings that may be used (depending on what is built) or that may be filled with a sealer, foam, or concrete or plugged as noted earlier.
As noted above, with the modular, compact, and removable configuration of the forming members and system, a wall or structure could be built in one or more layers, levels, sections or stages at a time—as is convenient for the user. (It should also be recognized that with such a configuration, only the spacer element, in some embodiments, is generally not reusable).
For example, two rows of forming members could be formed up and reinforced with rebar, and then concrete could be poured. After the concrete hardens, the same forming members could be dissembled and used at a later time (e.g., over another weekend, etc.) to form up, tie in and pour another section of the wall. The same process could be followed—or be stopped and started as convenient for the user—until the desired building structure is completed. With such features, the forming system could readily be used, at a person's convenience, for example, in a person's backyard for weekend projects or the like.
In certain embodiments, it should be noted that the footings of wall sections (or the walls) could also have varying widths. For example, one footing section could have a width of eight inches (e.g., to support a wall of eight inches) and be connected to another footing section with a width of ten inches (e.g., to support a wall of ten inches). Thus, for example, in one embodiment, a selectively configured forming member would be provided and serve as an interface forming member to transition between walls of varying widths. Such an interface forming member would be configured such that each panel (e.g., modified panels 12, 14) would have extensions bent outwardly at a desired location away from the passageway (e.g. 16). Each of the panel extensions would extend sufficiently such that the interconnectable ends and slotted elements would be lined up and be interengageable with the interconnectable ends and slotted elements of the wider forming member. For example, panel extensions would be added to the eight-inch wide form so as to position and line up the interconnectable ends and slotted elements thereof such that they would be interengageable with the corresponding interconnectable ends and slotted elements of the wider ten-inch forming member—and be connectable with an engagement member (e.g., 68). In this way, an appropriate structural interface would be established between adjacent formed up walls with different widths.
Referring again to
In addition, the panels are preferably connected with two uniformly configured spacer connectors. In other possible embodiments, however, each panel may be much larger or smaller and the number of spacer connectors can be increased or reduced as suitable.
It will be appreciated that a given forming member (e.g., 10, 172, 310, 230, etc.) may be used in certain situations without any spacer connectors. This is because, in a possible embodiment, as noted, a forming member (for example, 10, 172) has a pair of interconnectable ends (e.g., 18, 30 and 20, 32), at both ends (e.g., 180, 182), respectively, of the forming member (e.g., 10). Each of the ends 180, 182 of forming member 10 is adapted to be interconnected to complementary ends of adjacent forms. The interconnection with the adjacent forms, in some instances, may be sufficiently tight and firm to hold the panels of a given forming member in spaced relation without the need for having to install spacer members, connectors, standoffs, etc., to maintain the desired spacing.
In another possible embodiment of the present invention, with some features being similar, in one embodiment, to those in
Moreover, each of the at least two panels (for example, items 12, 14 in one possible embodiment) of the forming system are adapted to be disconnectable, after retaining the first supply of settable material to subsequently receive a second supply of settable material.
The forming system also preferably further comprises a plurality of forming members with the plurality of stacked forming members defining a wall of forming members defining a plurality of vertically-extending passageways for retaining a material. In one example embodiment, such a configuration is similar to that described above with respect to
In addition, in another possible embodiment, the forming system may also comprise at least two panels wherein each of the at least two panels comprises at least one interconnectable end defining a securable flange. The securable flange is preferably adapted to be interconnectable with a corresponding securable flange of another forming member. The forming system preferably further comprises an engagement component adapted to interconnect a securable flange (which in some embodiments, may form apertures adapted to be interconnected with other securable flanges by engagement components such as fasteners, connectors or the like) (as noted above and/or as noted in the embodiments explained hereinafter) of the forming member, with a corresponding securable flange of another forming member. It should be noted that in some embodiments the securable flanges may be slotted, however in other embodiments the securable flange may not be slotted. Moreover, in some embodiments, the engagement component may have a configuration similar to the engagement member described in the various embodiments described above and as follows; however, in other embodiments, the engagement component may have an unslotted configuration or some other different configuration adapted for securing the securable flange and corresponding securable flanges together. Such securing structures may comprise structures as described earlier herein or hereinafter or they may comprise clamping or vice grip-like devices, threaded or unthreaded fasteners, as well as other suitable securing systems and devices known in the art.
In one other embodiment, the forming system comprises a forming member comprising at least two panels in spaced relation so as to define a passageway adapted to retain a first supply of settable material. In such an embodiment, and in view of the interconnectable ends shown in
With this configuration and in view of other various features as noted herein, a plurality of walls of forming members may be interconnected so as to form at least a portion of an enclosure. Such an enclosure may be a shed, well or pool house, garage, home or addition, wall, or other building structure.
The forming system, in another possible embodiment also preferably comprises a forming member further comprising at least one spacer connector comprising a spacer element and a reusable connector, with the at least one spacer connector adapted to releaseably connect the at least two panels in spaced relation. The spacer connector and panels, in one example embodiment, have a configuration that is similar to that described above with respect to
In one other possible embodiment, the forming system may comprise an alternate forming member configured such that a first end comprises a pair of interconnectable ends 18, 30 (with or without slots) of a forming member 10 as shown in
With such a configuration, a pair of interconnectable ends 18, 30 of an alternate forming member would not need a specially configured interconnectable element defining an interengageable slot (like that shown in
In addition, it will be appreciated that the above configuration is specially configured such that the first and second ends of two adjacent “alternate” forming members may be interconnected—without the use of an engagement member.
In other words, in one possible embodiment, a forming member preferably comprises a first end which comprises a pair of interconnectable ends, ears or securable flanges (e.g., configured similar to 18, 30 of forming member 10 but without defining any interengageable slots), protruding away from the passageway and being disposed substantially orthogonally with respect to its panel. The second end of the forming member may comprise a pair of different but corresponding flanged interconnectable ends (configured somewhat similar to flanged interconnectable end 280 (shown in
Thus, in view of the versatility and configurability of the forming member, in a possible embodiment, forming member 10 may include at least one but preferably two interconnectable ends with each interconnectable end defining a securable element or flange—with or without a slotted configuration. However, in another example embodiment, each of the securable elements, may, for instance, define, form, and/or comprise an interengageable slot, respectively or other securable structure. Each interconnectable end may also define a securable flange or other element and each of the securable elements, in one example embodiment, may, for instance, define, form, and/or comprise an interengageable slot respectively.
In one other possible embodiment, a forming member comprises at least two reusable panels with each panel being of one-piece construction comprising at least one of sheet metal or plastic. The forming member further preferably comprises at least one spacer connector (in one embodiment, similar to that described with respect to
Referring now to
In addition, in some embodiments, the panels may form only a single complementary pair of apertures to accommodate only one selectively located spacer connector. As noted above, in other example embodiments, a pair of panels may not have any apertures formed therein and the panels may be held in spaced relation when interconnected to an adjacent forming member being secured in spaced relation by spacer connectors (or end forming members or end panels). For example, spacer connectors may only be installed in every other interconnected forming member.
