The present disclosure relates to building materials and systems and, more specifically, to systems and methods associated with finishing of an edge of an insulating concrete form (ICF) construction.
The statements in this section merely provide background information related to the present disclosure and may not constitute prior art.
As is known in the construction art, modern building construction often includes construction of concrete walls with insulated concrete forms (ICF's) that are composed of a foam insulating material that form permanent concrete form walls. ICF construction sandwiches a heavy, high-strength reinforced concrete between two layers of a light, high-insulation foam. This combination creates a wall with an unusually good combination of desirable properties: air tightness, strength, sound attenuation, insulation, and mass.
These ICF walls are constructed by placing separate ICF building blocks on each other. Rebar is placed within a cavity formed by the ICF blocks. Concrete is then poured and the walls are formed with the ICF blocks being left in place, even after the concrete hardens. The concrete wall so formed can include foundation walls and other building walls. Generally, further insulation is not necessary. Such walls can be externally finished such as with veneers, stucco, gypsum boards, and brick on the interior and exterior of the wall as required. The ICF blocks are typically made with two opposing expanded polystyrene side panels that are arranged in spaced parallel relationship with their inner surfaces facing each other to form a cavity therein. Plastic or metal bridging members can be molded into the side panels to hold them together to form the blocks and to hold them against the forces applied by the poured concrete within the cavity. Typically, an end plate is molded within each side panel as an internal “stud” for attachment of finishing materials. The bridges are typically attached to these end plates for structural support during the pouring of the concrete and for anchoring the endplate into the cured concrete. Re-bar is often placed horizontally and vertically within the cavities of the ICF blocks before the concrete is poured. The purpose of using re-bar is to hold the concrete in compression to provided added strength.
As these ICF blocks are stacked to form an ICF form wall, it is often necessary to form openings for doors, windows and system bypassing. These openings are often formed with block-out systems known as “bucks” that provide the openings as required within the ICF form wall before and after the concrete is poured. As with traditional construction, bucks have been utilized to provide such a block-out opening in the wall. Many of these conventional bucks are removable once the concrete has hardened, similar to the wood forms. These are often referred to as “reusable bucks”.
These bucks are typically built as wooden framed bucks that provide the opening in the wall. These can be removable or can be left in place similar to the ICF form blocks. If left in place after the poured concrete has cured, this wooden frame of the buck provides a fastening surface for the window or door and its finishing trim. The buck typically retains the concrete and also provides a point of attachment for interior and exterior finishes around the edge of the openings. In order to keep the wood frame properly aligned in the opening within the stacked wall forms, one or more temporary braces can also be used. These typically help to provide alignment of the wall forms with the wood frame. The buck typically requires supplemental bracing inside its frame to prevent deflection of the wood members under pressure from the poured concrete. This is usually accomplished by temporarily placing a brace between one or more side of the buck opening.
When the buck frame is to be left in the wall, it is typically secured to the concrete by one or more fasteners, such as nails or anchor bolts. These are positioned prior to the pouring of the concrete and are secured to the frame and left hanging between the side panels of the ICF system where the concrete will be poured. The subsequent pouring of wet concrete into the cavity causes the wet concrete to flow around the fasteners and partially secure the buck frame in place once the concrete has hardened.
Such bucks have been traditionally constructed of wood and plastic. However, these bucks have demonstrated a variety of problems. For instance, wood bucks are known to change dimensions over time as a result of variations in humidity, temperature, and pressure, such as during the actual construction process. Plastic bucks have been shown to deform similarly especially over time. Additionally, these plastic and wood bucks are not configured to endure substantial stress and do not offer strong bonds to the wall and as such can become easily dislodged from the wall.
As a result of the foregoing problems and disadvantages, there is a need in building construction for a more efficient, cost-effective and reliable systems and methods for forming openings and finishing edges in poured concrete walls made with permanent concrete forms such as insulated concrete forms (ICFs).
The inventors hereof have succeeded at designing edge finishing assemblies and methods that are capable of utilization during the construction of insulated concrete form (ICF) walls. These assemblies and methods can, in some embodiments, provide for improved ICF construction that include integrated structural support for roofing and windows and doors, improved edge finishes, and reduced construction costs, among other benefits and improvements.
According to one aspect, an assembly for finishing a top, side and bottom edge of an unobstructed opening in an insulated concrete form (ICF) wall formed from a plurality of insulating concrete form blocks each having two opposing side panels defining a cavity and an opening to the cavity each for receiving concrete therebetween and a plurality of internal structural supports positioned within the cavity. The assembly including an elongated monolithic body having two opposing parallel surfaces spaced apart and having an elongated lateral dimension for enclosing an end of one of the side panels of the insulated concrete form block wall forming an edge of the unobstructed opening of the insulated concrete form block wall and a portion of the opening to the cavity. The body has a first portion dimensioned for covering a portion of an outer surface of the side panel of the ICF wall proximate to the end of the side panel, a second portion for covering the end of the side panel and a third portion for extending inward towards the opening of the cavity of the ICF wall. The assembly also includes a plurality of retention members holes uniformly spaced apart and longitudinally positioned in a fixed position on an inner surface of the elongated body for receiving and securing a first end of a coupling device having a second end coupled to one of the internal structural supports securing the elongated body to the internal structural support before, during and after concrete is received within the cavity and during post construction use of the unobstructed opening finished using the assembly.
Further aspects of the present disclosure will be in part apparent and in part pointed out below. It should be understood that various aspects of the disclosure may be implemented individually or in combination with one another. It should also be understood that the detailed description and drawings, while indicating certain exemplary embodiments, are intended for purposes of illustration only and should not be construed as limiting the scope of the disclosure.
It should be understood that throughout the drawings, corresponding reference numerals indicate like or corresponding parts and features.
The following description is merely exemplary in nature and is not intended to limit the present disclosure or the disclosure's applications or uses.
In some embodiments, an assembly for finishing an edge of an insulating concrete form wall includes at least one elongated body having two surface portions coupled together with an intermediate portion positioned between the two surface portions in a substantially parallel position. The intermediate portion is dimensioned for enclosing an end of a side panel of an insulating concrete form block and a portion of the concrete within the wall. At least one of the two parallel surface portions is dimensioned for covering a portion of the side panel proximate to the end. The elongated body can be made of any material including metal or non-metals such as carbon fiber and other synthetics. The elongated body can be cut with standard construction tools and methods into any length.
A plurality of retention members are positioned along the at least one elongated body. Each retention member is adapted for receiving and securing a coupling device for coupling to an internal structural support member within the concrete of the wall. The retention members can be formed integral to the elongated body, such as integrally formed holes, tabs, loops, extension wings or portions, or can be formed as tabs or other members on one or more retention strips that are fixedly attached to a surface of the elongated body, such as by welding or adhesion, by way of examples. The retention members can be configured for receiving and securing the coupling devices, such as a tab or hook or other feature for receiving and securing a wire tie coupling device. In some embodiments, the retention members, or a strip containing one or more retention members, can be integrally formed with a coupling device that is configured for attaching to and securing with a structural member within a wall.
As generally described herein, a structural member within a wall includes any component providing structural support, including during construction prior to and during the pouring of concrete into the ICF wall cavity and/or following the pouring and curing of the concrete. For example, this can include rebar or wire or other metal bridges or wire placed in the cavity. The securing of the retention members with the securing devices to a structural member provides in some embodiments securing the assembly into the opening or along the edge to enclose the opening of the cavity to enclose the concrete when poured. This can also include providing structural strength and support for the assembly following the curing of the concrete including a structural tie between the assembly and the embedded structural members within the cured concrete. For example, a top cap having an assembly as described herein will have a strong structural tie into the concrete and structural members within the concrete for providing a secure attachment of a roof. Similarly, an edge defining an end or opening, a window frame, a door frame, a window jamb or a door jamb having a structural tie through the retention members and coupling devices to the structural members within cured concrete can provide for strengthened edge finishing including increased pull strength for inhibiting the displacement of the edge finishing from the ICF wall or roof/ceiling.

In such cases, the first elongated member can cover first sidewall and a portion of the cavity, the elongated expansion member generally covers the cavity but can overlap and cover one or both of the sidewalls. The second elongated member covers the second sidewall and can also cover a portion of the cavity. Each of the elongated members and the expansion member can include retention members that are coupled using coupling devices to structural members within the cavity of the wall. Each of the coupled members can be coupled using fasteners or fastening means, including screws or adhesives such as in overlapping sections. Additionally, seals can be placed between the overlapping members to provide a thermal barrier.
