Hughes, Norfolk, Va., assignor to Monowall Corporation, Norfolk, Va., a corporation of Virginia Filed July 28, 1966, Ser. No. 568,439 10 Claims. (Cl. 52293) The present application relates to a method for construction of a building wall, particularly a method for pro-casting and securing the reinforced building wall elements one to another. 1

Numerous previous inventors have devised reinforced building wall constructions, their principal object being to eliminate the high cost of building with conventional brick and cinder block. Basically these inventors have addressed themselves to the pre-castirm of building wall sheets and the securing of these sheets to the necessary footing, pilaster and bond beam elements. Needless to say, an efficient method of such construction can result in the saving of a great deal of time and money. According to the present invention, a building wall is constructed by pouring a reinforced footing extending beneath the building wall area and defining an upwardly disposed building wall receiving slot; pro-casting a bond beam designed to extend along the top of the building wall and defining a downwardly extending building wall receiving slot; pre-casting reinforced pilaster elements with inwardly disposed building wall receiving slots; pre-casting a reinforced building Wall sheet adapted for mounting between the footing, bond beam and pilaster elements and interlocking building wall sheet into the footing, bond beam and pilaster slots bond beam, sheet and footing and pilaster elements by reinforcing bar therethrough and grouting in place the reinforcing bars. The present method is distinguished in laterally rigidizing the building wall sheets by securing stiffener bars to the building wall sheets intermediate the bond beam and footing elements.

Accordingly, it is an object of invention to provide a method for the economical construction of a building wall, largely eliminating handwork.

Another object of invention is to provide a method for securing building wall sheet to footing, bond beam and pilaster elements.

Another object of invention is to provide a method for constructing an attractive, economical building wall.

FIG. is a schematic view showing the interlocking of the building wall, pilaster, bond beam and footing reinforcing bars so as to rigidize the entire structure;

FIG. 16 is a schematic view showing the interlocking of the stiffener bars with respect to the pilaster elements by means of the reinforcing bars extending therethrough;

FIG. 17 is a top plan showing the securing of abutting bond beam elements one to the other by means of the reinforcing bars;

FIG. 18 is a schematic view showing the locking of the bond beams to the pilaster elements by means of reinforcing bars extending therethrough;

FIG. 19 is a fragmentary end elevational view of the arrangement shown in FIG. 16 wherein the reinforcing bars extend from open area 46 into the adjacent pilaster for grouting in place.

In FIGS. 1 and 2,

building wall sheets

10 and 12 are shown as having their top 14 and bottom 16 secured in building

wall receiving slots

18, 20 and 28 in the respective bond beam 22 stiffener 24 and footing 26 slots. Bond beam 22 includes reinforcing bars 32, footing 26 includes reinforcing bars 36 and the

wall sheets

10 and 12 include reinforcing bar 29 extending from the footing 26 through the stiffener 24 and into the bond beam grouting area 30. Stiffener bar 24 may have horizontal reinforcing rods 34 extending therethrough and at each end into abutting pilaster faces. In FIG. 2 a typical steel joist and metal roof deck construction are illustrated in fragment.

The interlocking of the bond beam 22, pilaster 38, footing 26 and wall sheet elements are particularly illustrated in FIGS. 15-18. In the pilaster 38 reinforcing bars 42 extend from the pilaster into the footing. In FIG. 16 stiffener bar 24 reinforcing bars 34' overlap and extend through hole 44 and are grouted in the pilaster 38 thence into the opposed stiffener bar. An open area 46 is provided in the stiffener ends for chase filled with grout.

Similarly, the bond beam reinforcing bars 32' illustrated in FIGS. 17 and 18 extend into the chase filling area 48 in the abutting bond beam ends for overlapping and chase filling with grout. Lower reinforcing bars 32 extend from the bond beam 38 downwardly into grouting holes 50 in the pilaster 38 and are secured there by grouting.

In FIG. 3 there is illustrated the modification of invention where the stiffener 24 is eliminated.

In FIG. 4 there is shown the modification wherein a parapet 52 is secured on top of bond beam 22 by means of reinforcing bar 56 extending into the bond beam grout ing area 54. Also, the building wall sheet 10 is illustrated as having inner terrazzo facing 64.

In FIG. 5 the building wall is shown as having a rigid insulation 58 secured to its inner face.

In FIG. 6 identical opposed

building wall sheets

60 and 62 are mounted in spaced apart relationship to define an area 65 for the pouring of insulation or for dead air space and have on their exposed outer faces terrazzo, exposed aggregate or other decorative facing 64.

In FIG. 7 a modified stiffener 66 is shown as secured to the inner face of a building wall sheet by means of bolt assembly 70 grouted at point 72 to the building wall sheet face. Horizontal or vertical reinforcing bars 68 may be employed in stiffener 66 extending at either end of the building wall into the interlocking pilasters 38 or bond beams.

In FIG. 8 a masonry wall 74 is shown as secured to the building wall sheet by means of masonry ties 76.

In FIG. 9 there is shown the further modification wherein spaced apart panels 98 and are secured by means of stiffener 78, having reinforcing bars 80, and in turn secured to a load bearing bond beam 82 for multiple story construction. Bond beam 82 is secured to the stiffener 78 and the building wall sheets by means of steel bracket 83 having reinforcing bars 86 extending from the building wall sheets and reinforcing bars 84 extending from the bond beam.

In FIGS. 10-14 there are illustrated the expansion spaces 15 provided intermediate the building wall ends and the corresponding wall receiving slots in pilasters 38.

According to the FIG. 11 construction, angles or channels 92 are bolted to the pilaster to secure the inner building wall in place and channel separators 96 may be bolted to the pilaster to fix

building wall

60 and 62 in spaced apart relationship.

In FIG. 14 a corner pilaster 38 is illustrated.

It is estimated that building wall constructed according to the present invention can be installed for approximately one half the price of conventional concrete masonry block, particularly, where steel framework is required because of height. The building wall sheets and 12 can be secured in place by crane means and may have rectangular dimensions on the order of 15 to 25 feet. In pre-casting the

building wall sheets

10 and 12 door frames, windows and the like may be inserted in the wet concrete. Also, the

building Wall sheets

10 and 12 may be secured to the bond beams, pilasters and footing elements by cables (not illustrated). Decorative white cement as well as terrazzo faces or exposed aggregate or decorative design may be applied to the

sheets

10 and 12 in pre-casting. According to the modification illustrated in FIG. 9, plumbing, heating and like elements may be run in the spaces between parallel building wall sheets or these spaces may permit use of the structure as a fireproof wall or a refrigerator wall. It is proposed, also, that building wall constructed according to the present invention Will find wide application in the bill board industry.

The integral bond beam, footing and building wall structure created by this invention has in cross-section the appearance of an I-beam. Since the bond beam, building wall and footing are integrated by the overlapping reinforcing bars extending through their abutting surfaces, the structure has the strength and load-bearing characteristics of an I-beam. These characteristics are not inherent in previously constructed pre-castings.

Manifestly, various modes of pre-casting the individual building wall elements may be employed without departing from the spirit and scope of invention as defined in the subjoined claims.
