crete slab construction that is provided with reinforcin ribs on the inner face thereof.
A still urthe'r object resides in the provision of a concrete slab construction-of the above-mentioned character wherein wooden locks are set in the reinforcing ribs in such 29 a manner as to permit wooden strips to be attached thereto and across which wooden strips are secured the conventional laths whereby to provide a hollow wall structure with the usual plaster coating applied to the laths.
Another important object is to provide a concrete slab construction of the above-mentioned character which is simple, inexpensive, strong and durable and further well adapted for the purposes for which it is designed.
Other objects and advantages of the invention will become apparent from the following description when taken in connection with the accompanying drawings.
In the accompanying drawings wherein like reference characters indicate corresponding parts throughout the same;
Figure 1 is a view partly in elevation and partly in section of a portion of a building Figure 2 is a horizontal sectional view therethrough.
Figure 3 is a transverse section taken approximately on the line 3-3 of Figure 1.

line 6-6 of Figure 1 looking in the direction of the arrows.
In the drawings wherein for the purpose of illustration is shown the preferred embodiment of my invention, the numeral 1 designates a pre-cast concrete slab that is adapted to form one unit in the erection of the walls of a building. These concrete slabs may be of any predetermined size and formed on the inner face of the slab are the vertically extending reinforcing ribs 2 that are arranged in parallel spaced relation with respect to each other. These ribs further 00- operate to provide dead air spaces between the outer and inner walls of the building and wooden blocks 3 that are of trapezoidal shape in cross section are embedded in the ribs while they are in the plastic state and when the plastic material is set, it securely grips the inclined walls of the trapezoidal shaped blocks to maintain the same in position.
These blocks may have their outer faces projecting beyond the outer faces of the ribs as shown in the drawings or may lie flush with the outer faces of the ribs if so desired. These blocks provide a means -whereby wooden strips 4 may be secured thereto by any appropriate fastening means shown at 5 in Figure 5- and the wooden strips provide a means to permit the conventional laths that may be of wood or metal to be secured across said strips. These laths are denoted by the reference character 6 and the usual plaster coating may be applied to the laths whereby to form inner and outer spaced walls. By having the outer ends of the blocks projecting beyond the outer faces of the ribs 2, continuous or communicating dead air spaces are provided between the ribs while if the outer faces of the blocks lie flush with the outer faces of the ribs and the wooden strips are secured to said blocks, then the air spaces between the ribs are out of communication. These dead air spaces are designed to prevent moisture and frost from penetrating the inner wall.
Embedded in the slabs are bolts 7, and cavities 8 that open into the inner face of the slabs are formed to receive the threaded ends of the bolts and to accommodate the nuts 9.
The l-olts are adapted to provide a means for joining'the adjacent slabs together and interposed between the adjacent faces of two slabs 1s a strip of wood 10 that provides an air-tight connection between the adjacent edges of the slabs that form the side walls of the building that is being erected. In Figure 3 of the drawings, there is illustrated the manner in which two slabs that are disposed at right angles with respect to each other are joined together whereas in Fi re 4, there is illustrated the manner in W ich two slabs that are'disposed in the same horizontal plane are fastened together by bolts and nuts. In Fi re 6, there is shown in detail, the shape of the cavity 8 in order to facilitate ready and easy access to the nut 9' that is threaded on the threaded end of the securing bolt 7. X
Where the slabs are to be formed with window openings, wooden strips 11 are employed, the same being inserted in the mold before the slab is poured so that when the cement is poured, the wooden strips 11 will be maintained in proper position and when the concrete hardens, the strips 11 will be rigidly secured or embedded in the concrete, the inner opposed faces of the strips being beveled to form adove-tail grooxe with which interlooks a dove-tailed tongue 12 as shown very clearly in Figure 2. j The wooden frame 13 of the door or window is secured in the opening to the outer faces of the wooden strips 11 and 12 by any appropriate fastenin means. It is to be understood that the abs are cast in certain sizes and in the erection of a building, the slabs are positioned on the con crete foundation 14 provided for the joists 15 that extend across the top of the foundaconstruction and which will furthermore expedite the erection of concrete structures thus reducing the cost incident to the erection of a ment of my invention, it is to be understood that minor changes in the size, shape and arrangement of parts may be resorted to without departing from the spirit of the m-' vention or the scope of the appended claim.
What I claim is: r r
In a wall construction of the class described, pre-cast slabs having vertically disposed reenforcing ribs formed on the inner faces thereof, bolt-receiving openings formed in the adjacent edge portions of the slabs; and'cavities spaced from the ribs in the inner faces of the slabs and at the inner ends of said openings, bolts embedded in the edge portions of the slabs for disposition through the openings in the adjacent slabs, nuts arranged in the respective cavities on the threaded ends of the bolts to secure the adjacent slabs together in wall-forming relation.
In testimony whereof I afiix my signature.
-' FRANK T. BROOKS.
tion and suitable "fiooring will be secured across these joists. The slabs are set up vertically and the bolts 7 extend through registering openings formed in the adjacent portions of the adjacent slabs after which the nuts 9 are threaded on thevthreaded ends of the bolts to secure the slabs in wall-forming relation. The roof supporting timbers 16 are subsequently secured across the top of the structure and to this end, the top edge of each slab may have bolts extending upwardly therefrom for the purpose of securing the wooden sills in position as shown in Figure '1. When setting the slabs on the concrete foundation, cement may be poured between the wooden joists onto the top of'the foundation wall to firmly unite the wall slab to the founscription, that I have dation and to form a rigid floor base.
The inner wall is subsequently constructed 4 in the maner as heretofore described and the outer walls may have their outer faces coated.
with a protective coating or may have anornamental coating thereon if so desired.
It will thus be seen from the foregoing derovided a building unit in theform of a sla which is simple in
