United States Patent 3,485,003 WALL CONSTRUCTION AND BRICK SPACER ARRANGEMENT Wallace McDowell, 819 S. Lawrence St., Montgomery, Ala. 36104 Filed Dec. 14, 1967, Ser. No. 690,486 Int. Cl. E04b 2/30; E04c N10, N40

U.S. Cl. 52--415 9 Claims ABSTRACT OF THE DISCLOSURE The instant invention is generally concerned with wall construction, and more particularly relates to a preformed wall section or unit of a substantial size which is adapted for quick assembly with similar sections in the construction of both interior and exterior walls.

It is a primary object of the present invention to provide a preformed wall section of a hollow core nature which is adaptable for substantially any type of construction through the utilization of the hollow core for the reception of concrete, such as would be desired when providing a bearing Wall, heat insulation when a nonbearing exterior wall is desired, soundproofing for specific interior partitions, and premounted plumbing and electrical conduits and the like.

Another significant object of the instant invention resides in the provision of unique means for positioning and interconnecting the panels which comprise each section to form a rigid unit capable of functioning as either the finished wall itself or a combination wall and form for the reception of concrete or the like.

Further, an important object of the instant invention resides in the provision of mounting brackets to facilitate the mounting and to insure a proper positioning of facing bricks, should a brick wall be desired.

Basically in achieving the objects of the instant invention, a wall section is constructed of laterally spaced parallel panels interconnected by transversely extending rods which are normally provided in pairs, one extending inwardly through each panel and abutting the inner face of the opposite panel for providing a predetermined spacing between the panels. These rods are subsequently interconnected internally between the panels so as to form in efiect an integral rod member or connector with opposed abutments. When an external facing of brick is desired, selected ones of the rods are projected beyond one of the panels and mount outwardly projecting brick seating brackets upon which facing bricks are easily positioned for the subsequent introduction of grouting material therebetween.

These together with other objects and advantages which will become subsequently apparent reside in the details of construction and operation as more fully hereinafter described and claimed, reference being had to the accompanying drawings forming a part hereof, wherein like numerals refer to like parts throughout, and in which:

FIGURE 9 is a top plan view, with portions broken away for purposes of illustration, of another form of Wall section.

Referring now more specifically to the drawings, reference numeral 10 is used to generally designate the wall section or unit comprising the instant invention.

Basically, the unit 10, which is preformed in nature, is constructed by fixedly interconnecting a pair of laterally spaced flat parallel panels 12 of hardboard, plywood, or the like which, in conjunction with the rigidifying connectors or connector members 14 possess a substantial degree of rigidity capable of accommodating the introduction of a filler material, such as concrete, therebetween.

The connectors 14, in each instance, consists of a pair of elongated rods or rod- like members 16 and 18. The rod 16 extends through one of the panels 12, which can be considered the inner panel, and has the flat leading end 20 thereof abutting against the inner face 22 of the second or outer panel 12. This rod 16 also has an enlarged head 24 thereon received within a depression or recess in the outer face 26 of the first or inner panel 12 so as to appear flush with this outer face 26. The rod 18 extends through the second or outer panel 12 parallel and juxtaposed to the rod 16 with the fiat inner end 28 thereof abutting against the inner face 30 of the first panel. This rod 18 is of a substantially greater length than the rod 16 so as to project outwardly beyond the outer face 32 of the second panel 12 for the accommodation of a brick positioning bracket 34 thereon. The two rods 16 and 18 which comprise each connector 14 are welded or otherwise rigidly aflixed, as at 36, to each other between the panels 12 so as to define in elfect an integral unit having opposed panel locating abutments formed by the rod ends 20 and 28.

Each bracket 34 is associated with the projecting portions of a pair of adjacent rods 18 and is of a length which provides for a snug reception between the outer face 32 of the second or outer panel 12 and the enlarged heads 38 on the rods 18. In this manner, not only are the wall forming panels 12 interlocked, but mounting of the positioning brackets 34 is also effected.

Each bracket 34 will normally be of sheet metal or the like formed so as to define a central section 40 generally in the shape of an inverted U, a pair of outwardly directed horizontal flanges 42 integral with the lower portion of the central section 40, and a pair of downwardly directed flanges 44 integral with the outer edges of the outwardly directed flanges 42. Each bracket 34 is received over a pair of adjacent outwardly projecting rods 18 with these rods 18 seating in the angles defined between the adjacent flanges 42 and 44, after which the inner and outer end portions of the depending vertical flanges 44 are crimped or otherwise deformed about the corresponding rods 18 so as to effect a rigid attachment of the bracket 34 thereto. The specific construction and mounting of the brackets 34 will he readily appreciated from FIGURES 1-5 of the drawings.

As indicated supra, these brackets 34 are specifically provided for facilitating the mounting of a brick face on the outer panel. The bricks, as will be appreciated from FIGURE 1, are to rest upon the horizontal flanges 42 of a pair of adjacent brackets 34. The brackets 34 themselves are of a length less than the depth of the bricks so as to not project therebeyond, while the width of the central section 40 of each of the brackets 34 corresponds to the width of the joint defined between adjacent bricks in the same course. Furthermore, the height of the flanges 44 generally corresponds to the height of the mortar joint desired between adjacent courses of brick, each brick sliding, within allowable tolerances, rather snugly between adjacent brackets 34 and beneath a superimposed bracket 34 in the superjacent course of brackets. Upon a positioning of the bricks, the joints therebetween are filled with mortar or grout in any suitable manner, preferably through the utilization of a pressure hose or the like with the resultant construction presenting the appearance of a perfectly laid brick wall. It will be recognized that the use of these brackets 34, provided during the prefa'brication of the wall section 10, allows a construction of in effect a perfect brick wall by one other than a skilled brick layer.

As will be appreciated, the laterally spaced panels 12 define a hollow core within which it is contemplated will be accommodated appropriate plumbing and electrical conduits 46 and 48 preassembled for connection with mating conduits in adjacent sections whereby, upon an installation of the wall sections 10, a pre-wired construction will be effected, along with the simultaneous position of appropriate roughed in plumbing. In addition, the hollow core defined between the panels 12 can receive, at the option of the builder, any appropriate insulation, or for that matter a poured concrete filler. Further, the countersinking of the heads 24 of the rods 16 make it possible to apply a finishing coat of paint or plaster directly to the inner panel 12.

With reference to FIGURES 6, 7 and 8, it will be noted that a modified form of wall section 50 has been illustrated therein. This section 50 differs from the section 10 in that each connector 52 is defined by a pair of duplicate rods 54 extending inwardly through opposite ones of the panels 56 and having the flat inner ends 58 thereof abutted against the inner face 60 of the opposite panel 56. Each of these rods 54 in addition has an enlarged head 62 thereon positioned in a recess in the outer face 64 of the corresponding panel 56 so as to provide a flush appearance therewith. Finally, the two rods 54, between the panels 56, are rigirdly welded or otherwise afiixed to each other so as to in etfect constitute a single unit having abutment faces at the opposite ends thereof for the stabilization of the panels 56 relative to each other. With this particular construction, it will be appreciated that a similar hollow core is provided for the accommodation of the conduits, as well as the filler material. The outer faces of the two panels 56 are, in the finished construction, plastered, painted, or otherwise finished in any appropriate manner.

FIGURE 9 illustrates yet another form of wall section 70, this section 70 dilfering from the section 50 in that the connector 72 comprises a single rod having the opposite ends 74 thereof rigidly embedded within the opposed panels 76 with the spacing between the panels 76 being fixed by a pair of flat collars 78 on each rod 72 defining opposed abutments against which the inner faces of the panels 76 engage. Incidentally, the panel embedded ends 74 can, if so desired, have enlarged plates 80 afiixed thereto so as to cooperate with the plates or collars 78 and in effect sandwich the corresponding panels 76 therebetween, thus further stabilizing the construction.

From the foregoing, it will be appreciated that a novel wall unit has been defined, this unit comprising a preformed section constructed in a unique manner so as to achieve an adaptability to a variety of construction situations.

The foregoing is considered as illustrative only of the principles of the invention. Further, since numerous modifications and changes will readily occur to those skilled in the art, it is not desired to limit the invention to the exact construction and operation shown and described, and accordingly all suitable modifications and equivalents may be resorted to, falling within the scope of the invention as claimed.
