CONCRETE WALL CONSTRUCTION. 1

Application filed October 4, 1924. Serial No. 741,710.

To aZZ whom it may concern:

Be it known that I, ALONZO G. REYNOLDS,

a citizen of the United States, residing at San Francisco, in the county of San Francisco and State of California, have invented new and useful Improvements in Concrete lVall Constructions, of which the following is a specification.

This invention relates to concrete slabs for walls and has particular reference to the construction of a concretewall out of slabs adapted to be superimposed one upon the other and further to space two walls thus constructed so as to provide an airv space therebetween. 1

Another object is to provide means for; securing the slabs together previous to pouring the binding cement which'forms the i iv column. I

A still further objectis to provide meanswhereby a form is automatically constructed thus removing the necessity of a wood form for confining plastic concrete as 1s now com-' monly needed.

Other objects and advantages will be apparent during the course ofthe following description.

In the accompanying drawings forming a part of this specification, and in which like numerals are employed to designate like parts throughout the same,

Figure l is a cross section of a wall constructed in accordance with my invention, and

Figure 2 is a fragmentary perspective view of two of my slabs as they appear previous to being placed in a wall.

Inthe building of concrete walls,fit is now customary to build forms, lay re-enforcing bars in these forms, then pour concrete therearound to make a monolithic structure. This construction is expensive owing to the large amount of lumber which must be employed. Furthermore, the erection of the forms requires considerable time and labor.

I have formed slabs as designated by the numeral 5, which slabs are cast in suitable molds and have re-enforcing rods 6 cast therein. The-ends of these rods protrude at an angle from a point on one side of the block and near the end thereof. These protruding ends are designated by the, numeral 7 I It is preferable to form. a tongue .8 along one edge of the slabs so as to form an interlock between the next slab. above, which. is provided. with a suitable groove. The ends of the slabs are fashioned in the same manner, one of the grooves being shown at 9. At the sametime that I cast the slabs I insert near each end thereof,a sheet metal member 11. This sheet metal member has one end split and bent as shown in dotted lines in Figure 2, as indicated by the numeral 12.

These bent ends serve to securethe sheet. metal members in the concrete. when the same is poured. .In'each of these sheet metal members is provided securing slots .13, through which bolts 14 are adapted to be placed. This construction completes the forming of'a slab. v

flVhen the blocks thus formed are setin a wall, the result is that the sheet metalmem bers lie parallel with each other and the ends 7 of the re-enforcing rods cross each other. It is to be understood that a second set of slabs are placed parallel to the first set and in such a manner that the sheet metal members contact the sheet metal members of the first row of slabs. This ,will also cause the ends 7 of the second set to cross each other and at the same time lie in close proximity to the are passed through the slots 13 of the con tacting metal members 11 and tightened so as to hold the slabs in proper relation to each other, after which the concrete 17 is poured into the form thus constructed by the ends of the slabs and the sheet metal members. This concrete, upon hardening, forms an absolute look around the crossed ends 7 of the different slabs and at the same time forms a column, which gives the wall considerable strength. I

It will thus be seen that I have provided a very simple and efficient slab out of which a wall may be constructed in a minimum amount of time.

It is to be understood thatvthe form of my invention herewith shown and described is to be taken as a preferred example of the same, and that various changes in the shape, size and arrangement of parts may be resorted to without departing from the spirit of the invention or the scope of the subjoined claims.

Having thus described my invention, I clai1n 1. In a concrete slab of rectangular shape, a plurality of re-enforcing bars embedded in said slab and having the ends protruding therefrom on one side of said slab and near the ends thereof said protruding ends being diverging from each other, and a sheet metal member positioned in said slab near each end thereof so as to form parallel 6X- tensions at right angles to the surface of said slabs.

2. A wall construction comprising a plurality of slabs; re-enforcing bars positioned in said slabs, similar re-enforcing bars in the 15 and means for securing said sheet metal 20 members of said slabs one to the other.

In testimony whereof I afiix my signature.
