Pre-Engineered/Prefabricated Wall Assembly

Abstract

A pre-engineered/prefabricated wall assembly that has inner and outer sidewall panels of rigid insulation material that acts as both thermal insulation and concrete forms. The inner and outer sidewall panels are connected by connecting rods that secures a metal stud wall frame to the interior of the wall assembly, and a metal stud wall frame to the exterior of the wall assembly. The connecting rods serve to align the inner and outer sidewall panels separate from, and parallel to, each other, thereby providing a space for rebar and concrete to form a reinforced concrete wall. The mortar-less brick/stone veneer is attached to the wall assembly by inserting an attaching rod through the outer and inner sidewall panels, and is secured with a mechanical fastener, thereby securing the mortar-less brick/stone veneer in place until the poured concrete permanently secures the mortar-less brick/stone veneer to the exterior of the wall assembly.

2. Description of the Related Art

Homes, schools, hospitals and other residential and commercial buildings are sometimes constructed using the “Poured Cinder Block” building method where hollow cored cinder blocks (a.k.a. cement masonry units “CMU's”) are used. The cinder blocks are typically sealed in place with mortar so that the hollow cores of the cinder blocks face upwards. In poured cinder block wall construction, the cinder blocks serve as concrete forms into which concrete is poured to form a concrete wall. However, workers set the concrete forms (cinder blocks) only eight inches high and sixteen inches wide (approx. one square foot) at a time. The workers repeat this process over, and over, and then; using this extremely expensive and time consuming method of setting concrete forms, after enough blocks are laid, the cinder block forms are finally ready for the pouring of concrete. However, once the cinder blocks are laid and the cores filled with concrete, there is still no wall framing in place for the attachment of wall board or other wall coverings and to accommodate the placement of electrical wiring and other utilities; nor is there any thermal insulation in place. There is also no exterior furring strips or wall framing on the exterior side of the cinder block wall to accommodate the attachment of exterior sheathing, vinyl siding, wood siding, composite siding, or the attachment of wall ties for laying brick and other exterior veneers. In poured cinder block wall construction, the laying of cinder blocks, the erection of wall framing, and the placement of thermal insulation are operations separate and apart. These separate operations are very time consuming and greatly increases construction costs.

In poured cinder block wall construction, a concrete foundation is normally laid and then a row known as a “course” of cinder blocks are set in mortar on the foundation. Another layer of mortar is placed on top of the first course and a second course is then laid. In this manner a cinder block wall is constructed; but to achieve a cinder block wall that is both level and plumb, a great deal of skill and time is required. The time and skill required to construct a cinder block wall raises construction costs. Another problem with cinder block walls is that in their unfinished state they do not present a very pleasant appearance and therefore require finishing. Finishing a cinder block wall usually involves attaching a veneer such as brick or stone, painting, applying stucco, vinyl siding, or attaching some other type of exterior siding or veneer. The finishing of a cinder block wall requires considerable time and skill and adds substantial costs to wall construction. Another problem associated with applying exterior finishes to cinder block walls is that it is extremely difficult to attach siding materials such as wood siding, vinyl siding, metal siding, and other sidings to the hard surface of cinder blocks. To attach these siding materials, it is generally necessary to drill holes into the cinder blocks for the placement of metal or plastic anchors. Furring strips are then attached to these anchors, and in turn, the siding is attached to the furring strips. The attachment of these siding materials is both time consuming and adds considerable costs to wall construction. In most cases, it is also necessary to frame the interior of cinder block walls with wooden studs, metal studs, or furring strips to accommodate the placement of thermal insulation, the placement of electrical wiring, and for the attachment of gypsum board or other wall covering. This installation of wall framing is time consuming and also adds to the cost of wall construction. In an attempt to strengthen cinder block walls to withstand high velocity winds from hurricanes and tornados, sometimes steel reinforcement bar (“rebar”) is placed into the cinder block cores and then concrete is poured into the cores of the cinder blocks. The placement of rebar and the pouring of concrete into the cores of cinder blocks adds considerable costs to wall construction and in many cases does not accomplish the desired structural effect due to the fact that the concrete often “honey cones” when poured into the cores of the cinder blocks. Another problem with poured cinder block wall construction is the fact that a wall is as strong as its weakest point and the weakest point of poured cinder block walls are the mortar joints and the webs and end walls of the cinder blocks themselves. The honey coning and weak mortar joints and webs of poured cinder block wall construction are inherent weaknesses that renders poured cinder block wall construction structurally inferior to traditionally “formed” reinforced concrete wall construction. Structurally inferior poured cinder block walls are especially susceptible to wind loads from hurricane and tornado force winds when compared to traditionally formed reinforced concrete wall construction.

Various methods of solving the problems of poured cinder block walls have been put forward. A concrete “grout” has been developed that flows more evenly into the cinder block cores than does regular concrete. While this grout may help prevent honey coning and voids in the cinder block cores, it does not solve the problem of the structural weakness of the cinder block mortar joints, webs, and end walls, and does little to improve structural load factors involving hurricane and tornado force winds. Some have omitted erecting interior framing and elected to “glue” the wall board directly to the interior of the cinder block wall, however, when wall board is glued directly to the cinder blocks there is no space provided between the wall board and cinder blocks for the placement of thermal insulation or the placement of electrical wiring and other utilities. Therefore, for the construction of reinforced concrete homes and other residential and commercial buildings a pre-engineered/prefabricated wall assembly for the erection of reinforced concrete walls that solves the aforementioned problems is desired.

SUMMERY OF THE INVENTION

The subject pre-engineered/prefabricated wall assembly (“wall assembly”) incorporates numerous features into its wall system that reduces the time and cost of constructing a reinforced concrete wall. The wall assembly has the following components: The first components are the inner and outer sidewall panels that serve as forms to provide a space for the placement of rebar and the pouring of concrete. Since these inner and outer sidewall panels are constructed of polystyrene, polyurethane, or other rigid insulation materials, these sidewall panels also serve as thermal insulation that has a far greater “R-Value” than standard wall insulation, greatly conserving energy and reducing heating and cooling costs.

The second component is the wall framing attached to the inner sidewall panel consisting of a lower metal track and an upper metal track into which metal studs are placed to form metal stud wall framing. The metal stud framing provides a surface for the attachment of gypsum board or other wall covering and provides a space between the inner sidewall panel and the wall covering to run electrical wiring and other utilities. The metal stud framing is attached to the wall assembly by metal connecting rods and/or threaded bolts inserted through the inner and outer sidewall panels and secured with threaded nuts, speed washers, or other mechanical fasteners.

The third component is the metal stud framing attached to the exterior side of the wall assembly by means of connecting rods and/or threaded bolts inserted through the inner and outer sidewall panels and then secured with threaded nuts, speed washers, or other mechanical fasteners. The exterior wall framing may be used to attach wall ties for the laying of mortared brick, mortared stone, architectural concrete, and other exterior veneers; and for securing wood siding, composite siding, vinyl siding or other exterior sidings.

The fourth component is a mortar-less brick/stone veneer that also includes architectural concrete, and other exterior veneers used in wall construction. An attaching rod is attached to the back of the brick, stone, rock, architectural concrete and other exterior veneers by gluing, welding, screwing, or other means of attachment. Once the attaching rod is secured to the mortar-less brick/stone veneer, it is inserted through the exterior side of wall sheathing, the exterior side of insulated concrete forms (ICF's), the exterior side of cinder blocks, and through other wall materials, and is then secured on the interior side of said wall sheathing, wall forms, cinder blocks, insulated concrete forms (ICF's), and through other wall materials, with a mechanical fastener such as a speed clip (washer), threaded nut, or other mechanical fastener.

The wall assembly is pre-engineered in accordance with project drawings and are then prefabricated in various assembly sizes, complete with window and door openings, and window and door headers and footers. The prefabricated wall assembly is prefabricated with inner and outer sidewall panels that serve as both concrete forms and thermal insulation, with metal stud framing attached to the interior side of the wall assembly, with metal stud framing attached to the exterior side of the wall assembly, and is then shipped to the construction site ready to install. Since the wall assembly is both pre-engineered and prefabricated for an exact fit, the wall assembly is very easy to erect by only two workers, greatly reducing the cost of wall construction.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

The present invention is a pre-engineered/prefabricated wall assembly (“wall assembly”) designated as 100 in the drawings. FIG. 1 shows a perspective view of pre-engineered/prefabricated wall assembly 100. The wall assembly 100 is made up of several components making up a single unit as shown in FIG. 1.

The first of the components is the outer sidewall panel designated as 110 and the inner sidewall panel designated as 120 shown in FIG. 1 and in FIGS. 2A, 2B, 2C, 2D, 3A, 3C, 5A, 5B and 5C. Outer sidewall panel 110 and inner sidewall panel 120 serve to form a wall cavity for the placement of rebar and the pouring of concrete. Inner sidewall panel 120 and outer sidewall panel 110 are constructed of polystyrene, polyurethane, or other insulation materials to also serve as wall insulation that has a far greater R-value than the fiberglass insulation used in traditional building methods and therefore provide far greater savings on heating and cooling costs.

The second component to the wall assembly 100 is the interior wall framing fabricated with a lower metal track 200 and an upper metal track 210 into which metal wall studs 220 are attached as shown in detail in FIG. 1A, 2A, 2B, 2C, 2D, 2E, 3B,3C, 5A, 5B, and 5C. The metal wall studs 220 provides a surface for the attachment of gypsum board or other wall covering and also provides a space between the inner sidewall panel 120 and the wall covering to run electrical wiring and other utilities.

The third component to the wall assembly 100 is the exterior wall framing fabricated with a lower metal track 200 and an upper metal track 210 into which metal wall studs 220 are attached as shown in detail in FIG. 1A, 2A, 2B, 2C, 2D, 3B, 3C, 5A, 5B, and 5C. The metal wall studs 220 provide a surface for the attachment of wall ties for the laying of mortared brick, mortared stone, architectural concrete, and other exterior veneers; and for securing exterior wall sheathing, wood siding, composite siding, vinyl siding, and other exterior sidings.

The fourth component is connecting rod 230 and mechanical fastener 240 shown in FIG. 2B, 2C, and more fully defined in FIG. 2D. Connecting rod 230 is first attached to the interior wall framing and then inserted through inner sidewall panel 120, outer sidewall panel 110, and the outer wall framing and then secured on the exterior of wall stud 220 with mechanical fasteners 240. Connecting rod 230 is provided in various lengths to facilitate various spacing widths between inner sidewall panel 120 and outer sidewall panel 110 for the pouring of concrete in various wall thicknesses.

Wall assembly 100 is secured to the floor, the footing, or to the foundation of homes or other residential or commercial buildings using fasteners 510 as shown in FIGS. 5A and 5C. Wall assembly 100 is then secured to the adjacent and adjoining wall assemblies 100. In this manner a wall is thus formed and is ready for the placement of rebar and the pouring of concrete to form a wall with a solid reinforced concrete center.

The fifth component to wall assembly 100 is a mortar-less brick/stone veneer 310 as detailed in FIG. 3A, 3B, and 3C, and more fully defined in FIGS. 4A, 4B and 4C. A hole is first placed into the back side of the mortar-less brick/stone veneer 310. Attaching rod 410 is then inserted into said hole and secured by gluing, or other means of attachment.

Mortar-less brick/stone veneer 310 is attached to wall assembly 100 by first inserting attaching rod 410 through outer sidewall panel 110 and then through inner sidewall panel 120 and then securing attaching rod 410 with mechanical fastener 420 as detailed in FIG. 3A and 3B, and as is more fully detailed in FIG. 3C. Attaching rod 410 and mechanical fastener 420 secure brick/stone veneer 310 in place until concrete, grout, or other filler is poured into the space provided between inner sidewall panel 120 and outer sidewall panel 110. Once concrete or other filler is poured into the space provided between sidewall panel 120 and sidewall panel 110, brick/stone veneer 510 is permanently secured in place as shown in FIG. 3C.

The sixth component to wall assembly 100 is exterior wall sheathing 710 as shown in FIGS. 7A, 7B, 7C, 7D and 7E whereby the outer sidewall panel 110, along with lower metal track 200, upper metal track 210, and metal studs 220 are omitted to form a separate wall assembly constructed of metal track 200, upper metal track 210, and metal studs 220, along with inner sidewall panel 120 and exterior wall sheathing 710 attached to wall assembly 100 with connecting rod 230 and secured with mechanical fastener 240 as more clearly detailed in enlarged FIG. 7D.

By constructing the body of the different embodiments of the pre-engineered/prefabricated wall assembly described above, the inner and outer sidewall panels acts as concrete forms as well as thermal insulation, the metal tracks and studs located on the interior of the wall assembly forms interior wall framing for the attachment of gypsum board and other wall coverings, while the metal tracks and studs located on the exterior of the wall assembly forms exterior wall framing for the attachment of exterior veneers and sidings.
