Description
- This invention relates to construction of buildings using concrete forms. More particularly, this invention relates to a system adapted to temporarily carry a structural load of a building during construction, while the concrete cures, such that construction is not limited by the cure time of concrete components.
- Concrete forms for a concrete structure, such as concrete walls, are well known in the construction industry. Such forms are often referred to as Insulating Concrete Forms (or “ICFs”), and hold the shape of the concrete while it cures. Typically, opposing panels of Styrofoam® (Dow Chemical Co.), or other insulating foam panels are interconnected by braces that maintain proper spacing between the panels and maintain the desired form for the concrete structure while the concrete is placed and cured. The braces of opposing panels may also provide support for positioning rebar or other reinforcing materials between the panels while the concrete is being placed and is hardening. Although such foam panels with bracing are typically used, the panels could not independently support construction on a floor above while the concrete wall is being placed and cured.
- A series of vertical wall braces, referred to as “stiffbacks,” are typically placed on one or both sides of the concrete forms, secured to a base, and attached to the concrete forms to provide lateral support to the concrete forms during and/or after the concrete is placed. Diagonal braces also may be attached to an upper portion of the vertical wall braces to provide additional lateral support. Brackets or other similar structures may also be attached to the vertical braces near the top of the concrete forms to provide workers with access during assembly of the upper portions of the concrete forms and pouring of the concrete.
- Once the concrete forms and braces are fully assembled, concrete is placed into the concrete forms and allowed to harden. The stiffbacks and diagonal bracing provided support for the concrete forms while laterally supporting concrete placed and not yet cured. Also, such stiffbacks previously could not provide support for building construction above while supporting the placed, uncured concrete wall.
- In the case of multi-story structures, where an open web truss such as a steel truss, a corrugated metal subfloor and a concrete slab were typically assembled and placed for a second or subsequent floor, it was necessary to allow the concrete walls to harden so the concrete walls would provide the structural strength for the construction load of the floor assembly above before the wall braces could be removed and construction of the floor above could proceed. Also, removal of the braces from the walls typically was necessary before a concrete slab could be placed because the braces may extend above the walls and interfered with construction of the floor above. Therefore, the construction of the floor above a concrete wall would typically be separated from the construction of the concrete walls by one or two days, or more, substantially increasing the time and costs required for construction of the building structure. Additionally, the use of worker support and protection systems are typically required for the safety of workers for the installation of trusses and subfloor for the construction of the floor above, which further added to structural support needed from below and added to the time delays caused by curing of the concrete walls.
- Therefore, a need exists for a method of construction that provides temporary structural support for construction of a floor above, while concrete supporting walls are being placed and cured to provide permanent support for the building structure.
- The present invention provides a significant savings in time and cost in constructing a building structure using concrete forms, and an assembled floor above the walls. Prior systems required concrete to be placed in a concrete form wall system and allowed to cure upon a first day, followed by assembly of trusses and subfloor decking for the floor above on a subsequent day, and placing of a concrete floor on the following day(s). By contrast, the method of constructing a concrete structure provided herein allows the concrete formed walls and floor assembly above the walls to be erected and concrete wall and floor above to be placed on the same day as desired.
- A method of constructing a building structure is disclosed which allows construction of a floor or other construction above the wall to proceed while concrete walls are placed and cured. The method includes assembly of a plurality of adjustable braces attached to concrete forms capable of providing structural support for construction above and for an uncured concrete wall in the forms, where each adjustable brace has an elongated first support and an elongated second support dimensioned to enable the first support to slidably engage the second support. The first and second supports may be dimensioned to allow one to be telescoped into at least a portion of the other along their longitudinal length. A plurality of apertures are spaced along both first and second supports to allow the apertures in the first and second supports to align as the first and second support slide relative to each other.
