Robertson, Newington, and Philip Paolella, Hamden, Conan, assignors to The United Research and Development Company, Incorporated, New Britain, (301111., a corporation of Connecticut Continuation of application Ser. No. 470,699, Nov. 23,

1954. This application Mar. 2, 1964, Ser. No. 351,269 2 Claims. (Cl. 52-438) This application covers an improvement over a prior Patent No. 2,684,588, dated July 27, 1954, entitled, Plastic Filled Masonry Wall, by Alan L. Robertson; and it is also a continuation of the patent application of Alan L. Robertson and Philip Paolella, Ser. No. 470,699, filed November 23, 1954, entitled, Grouted Masonry Wall, and now abandoned.

This invention relates to building constructions, and more particularly to a load-bearing grouted masonry wall of great strength made up from a plurality of concrete building blocks of novel design.

One object of the present invention is to provide a masonry wall of the above nature in which the concrete blocks are provided with bottom horizontal grooves and end vertical grooves into which the grout will flow after each course of the wall is laid up upon the course beneath it.

A furtherobject is to provide a masonry wall of the above nature which is mounted upon a horizontal footing, and in which each block has an integral top cover cap below which are a plurality of hollow air cells opening into the bottom of the block.

A further object is to provide a grouted masonry wall of the above nature, in which each block comprises a part of the form for the next adjacent block when the grout is poured, thus eliminating the necessity of using external forms.

A further object is to provide a building block for a masonry wall of the above nature, in which the top and bottom surfaces of said block are ground to uniform height, with the top and bottom surfaces absolutely parallel so that the blocks may be laid dry with all sides and corners accurate and true. By means of this construction, if the bottom course is plumb, all of the superimposed upper courses will also be plumb.

A further object is to provide a masonry wall block of the above nature, having vertical end grooves and top horizontal grooves on its front face to provide imitation motor or shadow joints between adjacent blocks.

A further object is to provide a masonry wall of the above nature which will be simple in construction, very strong, inexpensive to manufacture, easy and rapid to install and manipulate, compact, ornamental in appearance, and very eflicient and durable in use.

With these and other objects in View, there have been illustrated on the accompanying drawings, several forms in which the invention may conveniently be embodied in practice.

In the drawings:

FIG. 1 represents a top plan view of one of the concrete building blocks embodying the invention, and showing in dotted lines an outline of the interior air cells, and the vertical end groove of said block.

FIG. 2 is a vertical cross-sectional view taken along the line 2-2 of FIG. 1.

FIG. 3 is an end view of the building block showing the location of the end and bottom grooves.

FIG. 4 is a perspective view of a masonry wall partially built up from a row of concrete blocks in staggered formation, and showing a pair of horizontal overlapping 3 $14,208 Patented Apr. 18, 1967 steel reinforcing rods located in the aligned bottom grooves of said blocks.

FIG. 5 is a cross-sectional view of the same, on a smaller scale, showing the air pockets in said blocks which are sealed by the grout poured into the vertical end grooves between the blocks when laying up each course of the wall.

FIG. 6 is a perspective view of a modified form of grouted masonry wall made up of a plurality of solid concrete building blocks arranged in vertical stacks and with horizontal and vertical reinforcing rods located in the aligned grooves thereof.

FIG. 7 is a perspective view of a masonry wall partially laid, employing shadow concrete blocks with inclined front faces to produce an imitation clapboard or shingle effect.

FIG. 8 is a cross-sectional fragmentary view of the upper portions of a pair of adjacent blocks of the third form of the invention.

Referring now to the drawings, in which like reference numerals denote corresponding parts throughout the several views, the numeral 10 indicates a concrete building block of rectangular shape having a pair of vertical interior air cells 11 and 12 covered by an integral top cap 13 and provided with integral vertical end walls 14, 16, an intermediate wall 15, and side walls 16a, 16b.

The numeral 17 indicates a horizontal bottom groove in the block 10, and the numeral 18 a vertical end groove communicating with the groove 17.

The first or bottom course of blocks 10 will be laid level and plumb upon a footing 19, as by employing a pair of horizontal leveling strips 20 and 21 of steel or reinforced concrete, as clearly shown in FIG. 4, or by a trowel and mortar. The leveling strips 20, 21 are adapted to be adjusted to level condition by means ofa plurality of shims 22.

A plurality of overlapping steel reinforcingrods 23 having hooked ends 24 are also arranged horizontally within the aligned bottom grooves 17 of the abutting blocks 10 in the course being laid.

The numeral 25 indicates the grout or other suitable fluent plastic binding material which is poured into the vertical end grooves 18, and which will pass down into the bottom grooves 17 and up into the interior air cells or cavaties 11 and 12 for a short distance, sealing the air in said cells, and serving to unite the blocks into an integral masonry wall construction without requiring the use of the usual exterior forms.

The grout 25 preferably contains a small amount of calcium chloride or any other suitable accelerating material to speed up the solidifying action thereof. This will permit the grout of each course to set before laying the next course.

In order to provide imitation horizontal and vertical mortar joints at the front of the wall, each of the concrete building blocks 10 and 11 is provided with horizontal and

vertical grooves

26, 27, respectively, which may be pointed with mortar after the wall has been laid. It is also essential that the top and bottom surfaces of each block 10 be ground into parallelism so that all superimposed courses of blocks will be plumb.

Second form In the second form of the invention shown in FIG. 6, a plurality of rows of the improved concrete blocks are laid in vertical stacked formation, one above the other, and are reinforced by vertical steel rods 31 and horizontal steel rods 32 located in the aligned end and bottom grooves respectively of said blocks.

In this form of the invention,

leveling strips

33, 34 may also be provided, and are laid upon a horizontal footing 35, as shown in FIG. 6.

3 Third form In the third form of the invention shown in FIG. 7, a plurality of shadow blocks 40 are arranged in a series of vertically spaced rows in staggered formation.

Each of the blocks 40 is provided with an inclined front face 41 so as to produce the effect of clapboards or shingles, and each block 40 is also provided with a groutreceiving end groove 42 and a bottom groove 43, as in the first form of the invention. One edge of the front face 41 is provided with a vertical groove 43a to give the appearance of a joint which may be pointed with mortar if desired.

Leveling strips 44, 45 are also provided, being laid upon a horizontal footing 46. Grout 47 will then be poured into the vertical and

horizontal grooves

42, 43 and will flow up a short distance into the

cells

48, 49 to seal the air therein, as in the first two forms of the invention.

While there has been disclosed in this specification a grouted masonry wall constructed of hollow concrete blocks, it is to be understood that any other artificial or natural stone, glass, metal or other building material may be employed, and that said blocks may be made solid if desired, within the spirit and scope of this invention.

While there have been disclosed in this specification several forms in which the invention may be embodied, it is to be understood that these forms are shown for the purpose of illustration only, and that the invention is not to be limited to the specific disclosures, but may be modified and embodied in various other equivalent forms without departing from its spirit. In short, the invention includes all the modifications and embodiments coming Within the scope of the following claims.

The invention claimed is:

1. A masonry wall construction comprising a plurality of horizontal courses wherein each such course includes a plurality of blocks each block having an imperforate horizontal and longitudinally extending substantially rectangular top wall, a pair of side walls depending respectively from the longitudinal edges of the top wall for the full length thereof and which have bottom surfaces residing in a common horizontal plane, a pair of end walls depending transversely from said top wall with one end wall flush with one end of the top wall and the side walls at one end of the block and with the other end wall spaced inwardly from the other end of the side walls to define a vertical recess opening through the top wall at the other end of the block, both of said end walls having bottom surfaces which are spaced upwardly from said common horizontal plane, each block also including at least one additional transverse wall depending from the top wall between said end walls and having its bottom surface spaced upwardly from said common horizontal plane, the blocks in each course being set directly on a lower course and being engaged in end abutting relationship with the said one end of one block engaging the said other end of the adjacent block in the course, and each course being completed by grout poured into the vertical recesses in the several blocks in the course, to flow over the top walls of the blocks in the course below in the space between the common horizontal plane of the course being poured and the bottom surfaces of all of the transverse walls and to fill the recesses of the course being poured and thus to bind the blocks in a course to each other and to the course below.

2. A masonry wall construction as set forth in claim 1 wherein one side wall in each block thereof is provided with a rectilinear exterior marginal recess extending along its bottom edge and its end edge at said one end of the block to define grooves in the wall to receive mortar as a trim for the wall construction and to further anchor the blocks therein.
