CONCRETE FORM SYSTEMS, DEVICES, AND RELATED METHODS

Description

BACKGROUND
Technical Field

The present disclosure relates to concrete form systems and devices, and related methods. More specifically, the present disclosure relates to concrete form systems and devices, and related methods that can be used to form structural concrete floors, or flat to slightly pitched roofs.

The Relevant Technology

Concrete is frequently used in the construction industry. For instance, concreate is commonly used in various aspects of building construction, including to form foundations, floors, ceiling, roofs, and walls. In such applications, cast-in-place concreate is frequently used. Concrete can be poured into a form and held in place by the form while the concrete cures. Once the concrete has sufficiently cured, the form may be removed or stripped from the concrete. This may include removing any bracing and form members.

While concrete, especially reinforced concrete, can be used to construct strong, stable buildings, there are some challenges encountered with concrete. For instance, when concrete is used to form a floor/ceiling between different stories of a building, ductwork, piping, and other conduits (e.g., for running cables, etc.) are often attached to the lower surface thereof (i.e., the surface that forms the ceiling). The ductwork, piping, and other conduits are then typically enclosed within drywall or other materials to hide them from sight. However, this can result in ceilings with undesirable appearances due to various portions being lower than other portions.

Additionally, concrete can have relatively low insulative properties (i.e., relatively low R-value), that make it difficult to efficiently control the climate within the building. For instance, it may be difficult to maintain different levels of a building at desired temperatures because heat from lower levels may rise through the concrete floors/ceilings to upper floors.

Accordingly, there are a number of problems in the art that need to be addressed. The subject matter claimed herein is not limited to embodiments that solve any disadvantages or that operate only in environments such as those described above. Rather, this background is only provided to illustrate one exemplary technology area where some embodiments described herein may be practiced.

BRIEF SUMMARY

In one example embodiment of the present disclosure, a concrete form system according to one example embodiment may include a concrete form and a rebar tree. The concrete form may include at least one support column disposed at a lower portion of the concrete form and first and second connection branches disposed at an upper portion or the concrete form. The first and second connection branches may be configured to be connected to second and first connection branches, respectively, of another concrete form. The first and second connection branches may at least partially form one or more channels therebetween. The rebar tree may include a rebar mounting assembly configured to hold one or more pieces of rebar in one or more desired positions. The rebar mounting assembly may be configured to be disposed within at least one of the one or more channels at least partially formed by the first and second connection branches.

In another example embodiment of the present disclosure, a concrete form includes first and second support columns, a bridge portion, and first and second connection branches. The bridge portion may extend upwardly from and between the first and second support columns to connect the first and second support columns to one another. The bridge portion and the first and second support columns may cooperate to define a channel in a lower surface of the concrete form. The first connection branch may extend upwardly from the first support column. The first connection branch and the bridge portion may cooperate to define a first channel in an upper surface of the concrete form. The second connection branch may extend upwardly from the second support column. The second connection branch and the bridge portion may cooperate to define a second channel in an upper surface of the concrete form.

In a further example embodiment of the present disclosure, a rebar tree that includes a shaft and a rebar mounting assembly. The rebar mounting assembly may be selectively and movably disposed on the shaft. The rebar mounting assembly includes one or more branches, each having one or more rebar retention elements configured to hold one or more pieces of rebar in one or more desired positions.

DETAILED DESCRIPTION

FIG. 1 illustrates an example embodiment of a concrete form system 100 that may be used to construct a structurally sound concrete floor or flat to slightly pitched roof in a building. In the illustrated embodiment, the form system 100 includes a plurality of concrete forms 102. While discussed in greater detail below, the concrete forms 102 may be positioned adjacent and/or secured to one another to create a concrete form of a desired size (e.g., the size of the concrete floor that is being formed).

The concrete form system 100 may also include temporary shoring elements 104 and/or roll bucks 106 that may be designed to support the concrete forms 102 while the concrete forms 102 are put into place, while concrete is poured therein/thereon, and while the concrete cures.

As in the illustrated embodiment, the temporary shoring elements 104 may include beams that are held in horizontal positions to support the concrete forms 102 thereon at a desired height. Although not illustrated, the temporary shoring elements 104 may be held in place by one or more posts or other temporary or permanent support elements.

The roll bucks 106 may be disposed at least partially within a channel or recess formed within a single concrete form 102 or a channel or recess formed by adjacent concrete forms 102. As can be seen in FIG. 1, the roll bucks 106 may be positioned on and supported by the temporary shoring elements 104. With the support of the temporary shoring elements 104, the roll bucks 106 can provide additional structural support to the concrete forms 102 while concrete is poured thereon and while the concrete cures.

Once the concrete has sufficiently cured, the temporary shoring elements 104 and the roll bucks 106 may be removed, leaving in place the concrete forms 102 and the cured concrete. With the temporary shoring elements 104 and the roll bucks 106 removed from underneath the concrete forms 102, various components may be secured to or within the underside of the concrete forms 102. For instance, HVAC ductwork, plumbing pipes, electrical conduits, etc. may be attached to or run through the concrete forms 102. Additional details regarding this aspect of the concrete form system 100 will be provided below.

With continued attention to FIG. 1, attention is also now directed to FIGS. 2-6, which illustrate perspective, end, side, top, and bottom views, respectively, of a concrete form 102 apart from the rest of the system 100. While the concrete form 102 is illustrated and described as having multiple various features, it will be appreciated that the illustrated embodiment is merely exemplary. The present disclosure contemplates any concrete form that includes one or more of the features disclosed herein in connection with concrete form 102.

As can be seen in FIGS. 2 and 3, the end of the concrete form 102 has a generally W or connected YY profile. That is, the concrete form 102 has first and second support columns 110a, 110b, first and second connection branches 112a, 112b, and a bridge portion 114. The bridge portion 114 is connected between the first and second support columns 110a, 110b. The first connection branch 112a and the bridge portion 114 extend upwardly from the first support column 110a. Additionally, the first connection branch 112a and the bridge portion 114 extend laterally away from one another so as to form a channel 116a therebetween. Similarly, the second connection branch 112b and the bridge portion 114 extend upwardly from the second support column 110b and laterally away from one another so as to form a channel 116b therebetween. As can be seen in the Figures, the channels 116a, 116b are disposed directly above the first and second support columns 110a, 110b, respectively,

The first and second connection branches 112a, 112b and the bridge portion 114 cooperate to define an upper surface of the concrete form 102. The channels 116a, 116b are recessed from the upper surface of the concrete form 102 so as to be able to receive concrete therein.

The first and second connection branches 112a, 112b include connection feature 118a, 118b, respectively. When multiple concrete forms 102 are positioned adjacent to one another, the connection feature 118a on one concrete form 102 may mate with the connection features 118b on an adjacent concrete form 102, as illustrated in FIG. 1.

In some embodiments, the connection features 118a, 118b may facilitate a secure temporary or permanent connection between adjacent concrete forms 102. In other embodiments, the connection features 118a, 118b may facilitate alignment between adjacent concrete forms 102 when the concrete form system 100 is being assembled. In still other embodiments, the connection features 118a, 118b may facilitate both alignment and secure connections between adjacent concrete forms 102.

In the illustrated embodiment, the connection feature 118a of the first connection branch 112a is a tongue and the connection feature 118b of the second connection branch 112b is a groove. In other embodiments, the connection features may include any mating or other features that facilitate connection and/or alignment between adjacent concrete forms 102. For instance, the connection features 118a, 118b may include mortise and tenons, dovetails, mating under and overlaps, and the like.

The first and second support columns 110a, 110b cooperate to define a lower surface of the concrete form 102. As can be seen in FIGS. 2 and 3, the first and second support columns 110a, 110b and the bridge portion 114 cooperate to form a channel 120 in an underside of the concrete form 102. The channel 120 is recessed from the lower surface of the concrete form 102.

Similarly, when two concrete forms 102 are positioned adjacent to one another, the two concrete forms 102 may cooperate to form another channel 120. That is, the first support column 110a and first connection branch 112a from one concrete form 102 may form a portion (e.g., half) of a channel 120. The second support column 110b and the second connection branch 112b from another concrete form 102 may form another portion (e.g., half) of a channel 120. More specifically, the first support column 110a and first connection branch 112a from one of the concrete forms 102 and the second support column 110b and second connection branch 112b from the other concrete form 102 may cooperate to form a channel 120. The channel 120 formed by two concrete forms 102 may be recessed from the lower sides of both concrete forms 102. As will be discussed in greater detail below, HVAC ductwork, plumbing, and/or electrical conduit may be run through the channels 120.

As can best be seen in FIGS. 2 and 4, one or more apertures 122 may extend (horizontally) through (e.g., between opposing sides of) the first and/or second support columns 110a, 110b. In the illustrated embodiment, the apertures 122 are circular and evenly spaced along the lengths of the first and second support columns 110a, 110b. In other embodiments, the apertures 122 may have other shapes. Likewise, the number and placement of the apertures 122 may vary from one embodiment to another. Furthermore, the apertures 122 in the first support column 110a may be aligned with or offset from the apertures 122 in the second support column 110b. Moreover, one of the support columns 110a, 110b may include one or more apertures 122 while the other support column may not include apertures 122 (or not the same number of apertures 122).

As illustrated in FIGS. 2, 3, and 5, each of the support columns 110a, 110b includes one or more apertures 124 that extend (vertically) therethrough between the channels 116a, 116b and the lower ends of the support columns 110a, 110b. Additionally, as shown in FIGS. 2, 3, and 6, each of the support columns 110a, 110b may have a channel 126 formed in a lower end thereof. The channels 126 may be recessed from the lower ends of the support columns 110a, 110b and may extend along all or a portion of the length of the support columns 110a, 110b. The purpose and functionality of the apertures 124 and channels 126 will be described below in connection with FIGS. 8 and 9.

While the concrete form 102 is described and illustrated as having a W or connected YY end profile, this is merely exemplary. In other embodiments, a concrete form may include a Y end profile. In such embodiments, the concrete form may include a single support column similar or identical to support columns 110a, 110b. Extending upwardly from the support column, the concrete form may include first and second connection branches similar or identical to connection branches 112a, 112b. In such an embodiment, the concrete form would have a single channel (similar to channels 116a, 116b) recessed into the upper surface of the concrete form. The concrete form would be configured to cooperate with one or more other concrete forms for form one or more lower channels (similar to channels 120).

Attention is now directed to FIGS. 7-9, which illustrate a system for positioning rebar or other reinforcement elements in desired locations within channels 116a, 116b. As is well understood, rebar or other reinforcement elements are commonly used in concrete to increase the strength of the concrete. As is also well understood, the rebar or other reinforcement elements need to be properly positioned within the concrete to provide the desired benefit.

When creating a concrete floor with the concrete form system 100, the system 100 is assembled and concrete is poured over the top of the concrete forms 102. The concrete fills the channels 116a, 116b. When cured, the concrete in the channels 116a, 116b may act as floor joists or beams. To provide the floor joists or beams sufficient strength, rebar or other reinforcement elements can be disposed within the channels 116a, 116b prior to pouring the concrete. To properly position the rebar within the channels 116a, 116b, a rebar tree 140 as shown in FIG. 7 may be used.

In the illustrated embodiment, the rebar tree 140 includes a shaft 142, a rebar mounting assembly 144 disposed on a first end or portion of the shaft 142, and a connection element 146 connected to a second end of the shaft 142. The rebar mounting assembly 144 may be movably connected to or mounted on the shaft 142. The connection element 146 may be permanently or otherwise connected to the second end of the shaft 142 such that the shaft 142 and connection element 146 are fixedly connected together.

In the illustrated embodiment, the rebar mounting assembly 144 includes a sleeve 148 that is disposed at least partially around the shaft 142. The sleeve 148 may be slidably disposed on the shaft 142 such that the sleeve 148 (and the rest of the rebar mounting assembly 144) may slide along at least a portion of the length of the shaft 142. The shaft 142 may include a threaded first end 150. A bolt 152 may be threaded onto the first end 150 of the shaft 142. As the bolt 152 is threaded further onto the shaft 142, the bolt 152 may engage the sleeve 148 and cause the sleeve 148 (and the rest of the rebar mounting assembly 144) to move down the shaft 142 towards the second end thereof (e.g., the end with the connection element 146).

The rebar mounting assembly 144 may include multiple branches connected to the sleeve 148, each with one or more rebar retention elements. In the illustrated embodiment, the rebar mounting assembly 144 includes four branches 154a, 154b, 154c, 154d. Each branch extends from opposing sides of the sleeve 148. Each branch includes one or more rebar retention elements 156. In the illustrated embodiment, the rebar retention elements 156 are channels mounted on or formed in upper surfaces of the branches 154a-154d. The channels may open upwardly such that rebar may be set into the channels. In other embodiments, the rebar retention elements 156 may be apertures that extend through the branches 154a-154d, such that the rebar may be slid into the apertures. In still other embodiments, the rebar retention elements 156 may extend downwardly from the branches 154a-154d and be configured to hold the rebar. Thus, it will be appreciated that the rebar retention elements 156 may take substantially any form so long as they can hold rebar in place while concrete is poured and cured.

The rebar tree 140 can be used in conjunction with the concrete form 102. For instance, as shown in FIG. 8, the rebar tree 140 may be disposed within the concrete form 102 such that the shaft 142 extends through one of the apertures 124 in the concrete form 102 and the rebar mounting assembly 144 is disposed within one of the channels 116a, 116b. This may be accomplished by removing the bolt 152 and the rebar mounting assembly 144 from the shaft 142. The first end of the shaft 142 may then be inserted up through the lower end of the aperture 124 until the first end of the shaft 142 is disposed in the channel 116a, 116b and the connection element 146 is disposed within the channel 126 of the concrete form 102. Thereafter, the rebar mounting assembly 144 can be disposed on the shaft 142 (e.g., by sliding the sleeve 148 onto the shaft 142). The bolt 152 can be threaded onto the threaded first end 150 of the shaft 142. As the bolt 152 is tightened, the connection element 146 is pulled into the channel 126 and the rebar mounting assembly 144 is secured between the bolt 152 and the lower surface of the channel 116a, 116b.

With the rebar mounting assembly 144 securely disposed within the channel 116a, 116b, rebar 158 may be disposed on or in the rebar retention elements 156, as shown in the channel 116a in FIG. 9. Optionally, additional rebar 158 can be positioned on top of the concrete forms 102, as shown as also shown in FIG. 9. Thereafter, concrete can be poured on the concrete form system 100. The concrete may fill the channels 116a, 116b and encompass the rebar 158. In FIG. 9, half of the concrete form system 100, including half of the channels 116a, 116b, are covered/filled with concrete and the rebar 158 is shown extend out of the end thereof for illustrative purposes.

Attention is now directed to FIG. 10, which illustrates an underside of the concrete form system of FIG. 1. As noted above, the concrete forms 102 are designed with apertures (e.g., apertures 122) and/or with or to form channels 120 that allow for HVAC ductwork, plumbing, and electrical conduit to be run therethrough. FIG. 10 illustrates a few examples of such. For instance, FIG. 10 illustrates a pipe 160 extending through a series of apertures 122 in the support columns 110a, 110b of the various concrete forms 102. The pipe may be a plumbing drainpipe or other water conduit. Similarly, FIG. 10 illustrates HVAC ductwork 162. As with the pipe 160, the ductwork 162 also extends through a series of apertures 122 in the support columns of the concrete forms 102. Additionally, at least a portion of the ductwork 162 also extends lengthwise through at least one of the channels 120.

FIG. 10 also illustrates ductwork 164. In contrast to the circular shape of the pipe 160 and the ductwork 162, the ductwork 164 has a square cross-sectional shape. Furthermore, the dimensions of the ductwork 164 are larger than the diameter of the apertures 122. However, in the illustrated embodiment, some of the apertures 122 have been cut larger and into square shapes to accommodate the ductwork 164. This can be readily achieved because the concrete forms 102 are formed of foam that can be easily cut to accommodate substantially any type of conduit. Furthermore, since the concrete forms 102 are not relied on to provide the floor with structural integrity or strength, cutting out portions thereof does not compromise the floor.

Once the floor is complete and any desired conduits are run through the concrete forms 102 (or before), a ceiling or ceiling components may be attached to the underside of the concrete form system 100. The ceiling or ceiling components may be attached to the concrete form system 100 via the connection elements 146 of the rebar tree 140. FIG. 11 illustrates one example embodiment of how a ceiling component can be connected to the connection element 146.

FIG. 11 illustrates the lower end of a support column 110a of a concrete form 102. The shaft 142 of a rebar tree 140 extends through the aperture 124 and the connection element 146 is disposed at least partially within the channel 126. A ceiling component 170 can be connected to the connection element 146. For instance, in the illustrated embodiment, the connection element 146 has a generally U-shaped profile and the ceiling component 170 has a similar profile. However, the ceiling component 170 is slightly larger than the connection component and has inwardly extending flanges 172. The ceiling component 170 may be slid onto the connection element 146 such that the flanges 172 extend over the upper ends of the connection element 146 in a manner to secure the ceiling component 170 on the connection element 146. Connecting the ceiling component 170 to the connection element 146 secures the ceiling component 170 to the underside of the floor. The remainder of the ceiling (e.g., drywall, tiles, etc.) may be secured to the ceiling component 170 with standard fasteners (e.g., screws, adhesives, etc.).

While the previous embodiments have focused on a system that uses a concrete form 102 and a rebar tree 140, it will be appreciated that this is merely exemplary. In other embodiments, a concrete form 102 may be used without a rebar tree 140. In such embodiments, the concrete form 102 may omit the one or more apertures 124 since they would not be needed for the shafts 142 of the omitted rebar tree 140. Similarly, the channels 126 in the concrete form 102 may be omitted or modified since the connection elements 146 of the omitted rebar trees 140 would not be present.

In such embodiments, the ceiling components 170 may be molded into or otherwise connected to the concrete forms 102 (e.g., with mechanical fasteners, adhesives, etc.). Additionally, rather than using a rebar mounting assembly 144 to position rebar within the channels 116a, 116b of the concrete form 102, rebar cages (such as pre-tied rebar cages) may be positioned within the channels 116a, 116b and used to reinforce the concrete disposed therein.

In light of the above, a concrete form system according to one example embodiment may include a concrete form and a rebar tree. The concrete form may include at least one support column disposed at a lower portion of the concrete form and first and second connection branches disposed at an upper portion or the concrete form. The first and second connection branches may be configured to be connected to second and first connection branches, respectively, of another concrete form. The first and second connection branches may at least partially form one or more channels therebetween. The rebar tree may include a rebar mounting assembly configured to hold one or more pieces of rebar in one or more desired positions. The rebar mounting assembly may be configured to be disposed within at least one of the one or more channels at least partially formed by the first and second connection branches.

In some embodiments, the at least one support column includes one or more apertures that extend laterally therethrough between opposing sides thereof, the one or more apertures being configured to have ductwork, pipes, or other conduit passed therethrough.

In another example embodiment, a concrete form includes first and second support columns, a bridge portion, and first and second connection branches. The bridge portion may extend upwardly from and between the first and second support columns to connect the first and second support columns to one another. The bridge portion and the first and second support columns may cooperate to define a channel in a lower surface of the concrete form. The first connection branch may extend upwardly from the first support column. The first connection branch and the bridge portion may cooperate to define a first channel in an upper surface of the concrete form. The second connection branch may extend upwardly from the second support column. The second connection branch and the bridge portion may cooperate to define a second channel in an upper surface of the concrete form.

In some embodiments, each of the first and second connection branches comprises a connection feature that can be configured for connection to second and first connection branches, respectively, of another concrete form.

In some embodiments, at least one of the first and second support columns includes one or more apertures extending laterally therethrough between opposing sides thereof and configured to have ductwork, pipes, or other conduits passed therethrough.
