BUILDING SLAB.

Application led April 17, 1924. Serial No. 707,08'5.

To all whom t may concern.'

Be it known that I, CLINTON W. SCHALL, a citizen of the United States, residing at Columbus, in the county of Franklin and State of Ohio, have invented a certain new and useful Improvement in Building Slabs, of which the following is a specification.

The object of this invention is to provide an improved slab of concrete designed for the rapid and economical construction of a wall. A further object is to provide a slab so constructed that when plastered upon its inner side or covered with plaster board or other material air spaces are provided for both horizontal and vertical circulation of air between the plaster side and the outer side so that dryness of the interior of the building will be promoted and conduction of heat either from the interior or to the interior lessened.

The invention is embodied in the example herein shown and described, the features of novelty being finally claimed.

In the accompanying drawing- Fig. 1 is a'view in elevation of the inner side of the slab.

Fig. 2 is an elevation of the right hand edge of the slab as seen in Fig. 1.

Fig. 3 is an elevation showing three of the slabs set edge to edge .as in erecting a wall.

Fig. t is a horizontal section on the line IV-IV Fig. 1 but on a magnified scale.

Fig. 5 is a detail in horizontal sectional View of two fractions of an outer wall showing how the vertical edges of two slabs can be tied together.

Fig. 6 is a detail with parts in vertical section showing how the concrete of the slab is reinforced and also showing how plaster board 0r plaster lath can be connected to the studding members of the slab.

In the views 7 designates the outer wall of the slab which is usually designed to be of somewhat more than room height and of about the width of two studding spaces. The characters 8 designates the studding members which are spaced apart at the usual or desired studding distance. Horizontally between the studding members and at each side beyond the studdings on each slab is a web 9 to support a beam of timber for a joist or rafter. The lower and upper ends of the slab are formed with flanges 10 and 11 respectively to rest on the buildings foundation and receive superposed slabs for the story above, such flanges also bracing the slab and the studding. The edges of the studding members are formed with several curved recesses 12 to permit air to circulate horizontally between the stu-dding and throughout the wall. The webs 9 are also similarly recessed at 9a to permit air circulation. The studding between the terminals of the recesses form lands that are provided with short pieces of lead pipe 13 embedded therein to receive lag screws, such as seen at 14 for securing to the studding metal lath or plaster board 15.

The slab is made as one piece out of concrete formed in a mold of the appropriate form and in the usual manner but preparatory to pouring the concrete two reinforcing rods 16 are provided for each studding member lto strengthen those members and before the outer wall member is completely or about poured I lay upon it a sheet of metal lath or so called expanded sheet metal 17 of such size as to leave margins 17a projecting at the edges of the outer wall member.

In erecting the slab the vertical edges are butted as shown in Fig. 3 and the margins 17 n bent inward and tied together with short pieces of wire as shown in Fig. 5. After the wall has been erected the joints can be pointed up, if necessary, and a coat of stucco or other ornamenting material applied. When the slabs are thus erected the webs 9 afford practically continuous rests for the joist, beams or rafters as suggested at 18 in Fig. 3.

The forms of the parts can be changed somewhat without departing from the gist of the invention as claimed.

What I claim is:

1. A building slab of plastic material including integrally an outer Wall member provided with an inwardly extending studding member, a horizontal flange projecting inward from the upper end of said Wall, and a horizontal beam-supporting cross web spaced from said end flange and intersecting the studding member.

2. A building slab of plastic material including integrally an outer wall member provided with an inwardly ext-ending stud ding member, a horizontal flange projecting inward from the upper end of said wall, and a beam-supporting cross web spaced from said end flange and intersecting the studding member, said beam-supporting and studding member havingtheir inner edges provided with Ventilating recesses and plaster-supporting lands between said recesses.

3. A building slab of plasticy material including integrally an outer Wall member provided With inwardly extending top and bottom anges, a studding member on said Wall extending between said flanges Vand having recesses .for horizontal ventilation and a beam supporting cross Web intersecting at right angles ,the studding member.
