Field of the Invention The present invention generally relates to a wall construction and more particularly a masonry wall constructed of a plurality of modules of predetermined standard sizes such as 8 inch X 4 inch panels together with structure for erecting a wall in a manner to effect a considerable saving in time and labor. 2. Description of Prior Art Conventionally, masonry walls are constructed from bricks, concrete blocks or the like in which the individual bricks or blocks are laid by hand which results in a substantial cost for time and labor of the skilled artisan engaged in this work. Some efforts have been made to reduce the expense involved in constructuon walls but most efforts have been directed toward the concept of pouring a complete wall as a monolithic slab either in situ in a vertical position or in a horizontal position with the complete wall being tilted upwardly to a vertical position after formation. Other efforts have been made to prefabricate complete building walls at a factory site and then transport them to a building site for installation. However, such procedures require rather elaborate machinery, forms and the like to form a complete wall and eliminate flexibility in design, size and the like of a wall.

SUMMARY OF THE INVENTION An object of the invention is to provide a wall structure comprising a plurality of standard size modules and an apparatus for setting up the modules into a wall structure which enables the modules to be constructed at a point remote from the building site and effectively transported thereto and then erected to form a building wall or the like without requiring the use of elaborate machinery, transportation equipment or erection equipment.

A further object of the invention is to provide a ,wall structure employing a plurality of modules together with a knee brace for erecting the initial course of modules and alignment brackets for erecting subsequent courses of modules with the knee braces and alignment brackets being secured by ties disposed in the mortar bed or joint between adjacent modules.

Another important object of the present invention is to provide a bracket structure for aligning courses of wall modules which engage the vertical surfaces of the modules and include adjustment means to enable limited adjustable vertical orientation of the upper module to properly align it vertically with a lower module.

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 thereof, wherein like numerals refer to like parts throughout.

DESCRIPTION OF THE PREFERRED EMBODIMENT Referring now specifically to the drawings, a building wall 10 is disclosed and is constructed from a plurality of substantially identical modules 12 each of which may be 8 inches X 4 inches in dimension and is in the form of a panel having vertically disposed substantially parallel face surfaces which may be provided with any pattern desired such as simulated brick, stone, concrete block or the like or the panel may have a plain concrete appearance and for the purposes of this application will be defined as a substantially rectangular rigid panel 14 provided with passageways 16 for utility lines and suitable reinforcement (not shown) may be provided in each of the panels to rigidify the same.

The first course of modules 12 are oriented vertically and retained in position by a knee brace 18. The first course of modules may be supported in any suitable manner such as on a foundation, footing, concrete slab or the like in a well known and approved manner in the building industry with the vertical joint between adjacent modules being filled with mortar to provide a sealed joint therebetween. Subsequent courses of modules 12 are positioned on the lower course in alignment therewith with the joints staggered and with a mortar bed between the modules with a bracket assembly 20 being employed between the lower course of modules and an upper course of modules.

The knee brace 18 is illustrated in more detail in FIG. 7 and includes a lower angle iron member 22 and an upperangle iron member 24 interconnected bya turnbuckle assembly 26 to longitudinally adjust the

members

22 and 24 in relation to each other. The lower end of the member 22 is provided with a pointed ground stake 28 adjustably attached to either flange of the member 22 by a plurality of holes 30 provided therein receiving'a'fastener bolt or pin 32 so that either of the flanges of the member 22 may be disposed vertically with the stake 28 being pivotal and oriented vertically when in use as illustrated in FIG. 1. The upper end of the upper member 24 is provided with a longitudinally adjustable angle iron extension 34 having longitudinal slots 36 therein receiving handle-equipped fastener bolts 38 to provide a further adjustment of the overall length of the knee brace. The upper end of the extension 34 is pivotally attached to an angle iron member 40 having a reinforced slot 42 therein which receives a generally triangular shaped end 44 of a tie 46 that is embedded in the mortar bed and thus anchored to the wall or a suitable means may be provided for anchoring,

the tie to the lower course of modules 12. A wedge 48 is inserted vertically down through the triangular shaped loop or eye 44 with one surface of the wedge engaging the bracket 40 above and below the slot 42 thereby securing the bracket flat against the lower module 12 so that by adjustment of the turnbuckle 26, the lower module 12 may be accurately positioned in vertical orientation.

The bracket assembly 20 includes a rigid one-piece angle iron unit 50 bridging the horizontal joint between the lower and upper course of modules 12 with one flange of the member 50 having a reinforced horizontal slot 52 therein for receiving a triangular eye or loop 54 on one end of a wire tie 56 that includes a similar loop or eye on the other end thereof and is provided with a central offset 58 which is disposed between the courses of modules and received in the mortar bed. The loop 54 extends through the slot 50 and receives a vertically disposed wedge 60 tethered to the member 50 by a flexible chain or the like 62 so that one flange of the angle iron member 50 is secured flush against the aligned surfaces of the lower and upper modules.

Each bracket assembly 20 also includes a two-piece component generally designated by numeral 64 which includes a lower angle iron member 66 having a reinforced horizontal slot 68 adjacent the upper end thereof which receives the eye or loop 54 on the end of a wire tie 56 with a vertical wedge 70 being received therein and tethered to the angle iron member 66 by a flexible chain 72 or the like so that angle iron member 66 will be fixedly secured to the surface of the lower module with the upper end thereof bridging the joint between the upper and lower panels 14 which form the modules 12 as illustrated in FIG. 2. The two-piece component 64 of the bracket assembly 20 also includes an upper angle iron member 74 having a downwardly extending leg 76 on one flange thereof and forming a continuation thereof which is pivotally attached to the outwardly extending flange of the angle iron member 66 adjacent the upper end thereof by a pivot pin or bolt 78. The flange on the angle iron member 66 to which the leg or extension 76 is pivotally attached includes a triangular shaped opening 80 and the inner edge of the extension 76 is provided with a smaller triangular shaped notch 82 communicating with the inner edge for receiving a horizontally disposed wedge 84 that is tethered to the angle iron member 74 by flexible chain 86 or the like. Thus, by inserting the wedge 84 horizontally as illustrated in FIG. 3, the notch 82 and the extension 76 will engage the inclined apex of the wedge and be forced outwardly as the wedge is inserted thereby clampingly engaging the surface of the upper module by swinging the member 74 inwardly about pivot pin or bolt 78 thus clamping the module against the one-piece component 50 and orienting the upper module in exact alignment with the lower module.

As illustrated, the wire ties may be provided with weakened point adjacent the outer ends to enable the outer ends thereof to be broken off after assembly of the wall. The weakened points may be in the form of notches 88 and the wire ties may be of well known structure which facilitate breakage thereof. Also, eyebolts or ties 90 may be provided in the top edge of each module to enable a crane or other lifting equipment to be employed to place the modules in position with these eyebolts either being removed or broken off after assembly of the modules. Also, each of the wedges are tethered to their associated structure to prevent loss thereof and enables assembly of the wall with very minimum toolsinasmuch as a conventional hammer or other impact instrument may be employed for securing the knee braces in position and also the bracket assemblies in position.

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 restored to, falling within the scope of the invention.
