The present disclosure relates to construction equipment, more specifically to concrete forming systems and assemblies comprising the same.
Modern concrete forming structures are typically erected using a plurality of prefabricated, interlocking form sections or panels which may be reused indefinitely to produce any number of concrete structures. The forms or panels are designed to be interconnected end-to-end as well as in opposed relationship, to present a wall form for example.
For purposes of end-to-end interconnection, the panels generally include vertically extending end walls having a series of spaced openings therethrough. When aligned in juxtaposition, the individual panels are typically interconnected, such as by means of slotted pin and wedge assemblies. When the form is disassembled, the wedges are loosened and removed, and the pins extracted from the form panel apertures.
These concrete form sections are necessarily of relatively high strength, yet preferably they are compact and lightweight to effect savings in handling, transportation, and storage. Hence, the sections are generally constructed from a panel of lightweight metal such as aluminum and have a reinforcing grid secured to the back side of the panel for providing the necessary strength to resist buckling under the weight of the poured concrete.
Significantly, the reinforcing grid assemblies can be bulky, which adds significant weight and/or size to the panels. Alternatively, concrete forms might require builders to manually assemble the reinforcing grid assembly for each concrete forming panel. This is a very time consuming process that requires the handling of multiple pieces of material to build and support a desired concrete form.
Despite the widespread use of such systems, there is still a need in the art for improved concrete forming systems.
The present disclosure provides a concrete form or panel system, as well as assemblies comprising the same, which addresses one or more of the above shortcomings.
In accordance with at least one aspect of this disclosure, a concrete form can include a forming wall including a concrete contact side and a bracing side and a plurality of braces movably connected to the bracing side of the forming wall, wherein the plurality of braces have two positions, a retracted position and a bracing position. In certain embodiments, the braces are configured to be reversibly moved and/or secured between the retracted position and the bracing position.
In certain embodiments, the forming wall is formed of a lightweight, durable material, e.g., plywood, aluminum or other metal, and the like. In additional embodiments the forming wall can include a plurality of cross-brace apertures, each cross-brace aperture disposed between a pair of braces. Each of the cross-brace apertures can be accessible when the braces are in either of the retraced position and the bracing position. The plurality of cross-brace apertures can include different sizes to accommodate different portions of a tapered connection rod. In certain embodiments, the concrete contact side of the forming wall can include a coating for preventing concrete from adhering thereto.
In certain embodiments, the braces of the form can include at least one I-beam. In additional embodiments, at least one of the plurality of braces can be a scaffold member. In still additional embodiments, the scaffold member can include a plurality of holes defined therein to reduce weight of the scaffold member.
In certain embodiments, the concrete form can further include a control bar operatively connected to each brace to move the plurality of braces between the retracted position and the bracing position. In additional embodiments, the control bar can be hingedly connected to at least one of the braces. In certain embodiments, the control bar can extend through the scaffold member.
In certain embodiments, the concrete form can further include two angled bracket members attached to opposite edges of the forming wall and configured to receive a hinge pin therein. In additional embodiments, the hinge pin can be configured to hingedly mount each brace to the bracing side of the forming wall. In still additional embodiments, each angled bracket member can include a keyhole fastener slot for joining a plurality of concrete forms together.
In certain embodiment, the concrete form can include a plurality of brace stops operatively disposed on the bracing side of the forming wall and in communication with each brace such that each brace stop aligns each brace perpendicular to the forming wall. In certain additional embodiments, the brace stops can include angled bracket members disposed on the bracing side.
In additional embodiments, the scaffold member can include scaffold supports configured to support the scaffold member when the scaffold member is in the bracing position. In certain embodiments, the scaffold supports can be hingedly mounted to the scaffold member to move between a folded position such that each of the scaffold supports is folded against the scaffold member, and a support position such that the scaffold supports are perpendicular to the scaffold member. In other embodiments, the scaffold supports can be triangular shaped members or any other suitable shape.
In another aspect, the description provides an assembly of a plurality of forms or panels as described herein. In a preferred embodiment, the plurality of forms are juxtaposed or in apposition, and reversibly interconnected in at least one of vertically, horizontally or a combination thereof.
These and other features of the systems and methods of the subject disclosure will become more readily apparent to those skilled in the art from the following detailed description taken in conjunction with the drawings.
So that those skilled in the art to which the subject disclosure appertains will readily understand how to make and use the devices and methods of the subject disclosure without undue experimentation, embodiments thereof will be described in detail herein below with reference to certain figures, wherein:
Reference will now be made to the drawings wherein like reference numerals identify similar structural features or aspects of the subject disclosure. For purposes of explanation and illustration, and not limitation, an illustrative view of an embodiment of a concrete form in accordance with the disclosure is shown in
In accordance with at least one aspect of this disclosure, referring to
In certain embodiments, the forming wall 101 is a lightweight but durable material. For example, in certain embodiments, the forming wall is selected from the group consisting of plywood, metal, e.g., aluminum, alloy, carbon fiber, plastic, or any other suitable material and combinations thereof. The forming wall can have any suitable thickness, length, and/or width. It is contemplated that the concrete contact side of the forming wall 101 can include any suitable coating for preventing concrete from adhering thereto.

Each angled bracket member 109 can include one or more keyhole fastener slot 109 for joining a plurality of concrete forms 100 together using a suitable fastener. The angled bracket members 109 can be made from any suitable material (e.g., aluminum). Any other suitable modular locking and/or connection mechanism is contemplated herein.

The scaffold supports 107d can include a suitable locking system associated therewith to removably lock the scaffold supports 107d in the support position. For example, a flange 121 can me mounted on the bracing side 101b of the forming wall 10 land can be configured to receive a locking pin 107f that attached to the scaffold supports 107d within a lock hole 121a. Any other suitable system to lock the scaffold supports 107d in the support position is contemplated herein.
Referring to
In certain embodiments, the control bar 113 can extend through the scaffold member 109 via hole 107c in scaffold member 107. In this manner, the control bar 113 can be attached to a surface defining the hole 107c in any suitable manner (e.g., via a hinge mounts 113a connecting to a mating mount 103a attached on an inner surface defining hole 107c).
