To all whom it may concern: A

Be it known that l, GROSVENOR A'rrnnnunr, a citizen of the United States, and a resident of the borough of Manhattan, city, county, and State of New York, have 111- vented certain new and useful Improvements in Sectional Cementitious Structures, of which the following is a description.

My invention relates to structures, in the nature of buildings, composed of slabs of concrete or other cementitious material and Y is of especial value in connection with,

though in no way limited to, such structures where the component slabs are of large size, for example, large enough so that a single floor slab may constitute an entire floor of the building, or of a room thereof, and a. single wall slab or a comparatively few such slabs placed side by side may constitute an entire wall of a story of the building.

An object of my invention is to provide slabs of the kind referred to, which shall be so formed as to enable them to be easily secured to the adjacent slabs, whether in the same plane therewith or at right angles thereto and so that the joints between the adjacent slabs may be rendered substantially water-tight, without resorting to the tedious and expensive hand operations now in use.

Another object of my invention is to so form the slabs that there will be in the completed tructure uninterrupted passages throu h the walls and floors, which may be used or the installation of pipes, conduits, wires, etc., either during the erection of the structure or at a subsequent time and for the circulation of fluids, such as water, steam, or other liquids or gases, to regulate the temperature of the structure and for similar purposes.

It has been found that under the present practice of joining together adjacent wall slabs of structures, it is almost impossible to prevent a driving rain from leaking through age of this moisture into the interior of the wall slabs, I provide the upper and lower surfaces of the outer edge of the floor slabs with rabbets or similar devices, which efi'ec tually accomplish the desired result. In addition to the features of construction above referred to and the method of constructing buildings of slabs embodying these features, my invention includes the various other articles, combinations and steps described in the specification and more fully set forth in the claimappended thereto.

In the drawing,

Figure 1 is a perspective view of a portion of my improved structure with the upper wall slab removed from the floor slab for the sake of clearness;

Fig. 2 is a longitudinal section of a por- Filtion of my improvedstructure, showing the method of finishing the joints between the wall and floor slabs;

' Fig. 3 is a similar longitudinal section,

but is taken through a wall at right angles to the wall of Fig. 2;

Fig. 4 is a similar longitudinal section taken at a diflerent point in the wall illustrated in Fig. 2;

Fig. 5 is a horizontal sectional view ofa portion of a wall of my improved structure, showing particularly the method of securing together adjacent wall slabs.

The wall slabs shown in Fig. l are desig nated by the reference numeral 6 and the floor slab by the reference numeral 7. As

shown? the floor slab 7 is rabbeted on its upper surface near the outer ed e thereof at 8, 9 adapting it to receive the lower edges 10, 11 of the upper wall slab, as shown for instance in Figs. 3 and 4. The floor slab 7 is rabbeted on its lower surface near the enterior edge thereof at 12 to receive the upper flat surface 13 of the lower wall slab. ,As a result of this rabbeting, it is apparent that the walland floor slabs will be anchored together without the use of the customary metal or other anchors.

Each of the wall slabs is provided with a plurality of voids extending vertically therethrough. In the embodiment of my invention shown herein, each wall slab is provided with three such voids designated in Fig. 5

Nit?

as 14, 15 and 16. It will be noted, by reference to Fig. 3, that the voids 15 are reduced or built in at the top to form the small openings 17. The purpose of this building in, is to provide a more extended bearing surface for the joint between the wall and floor slabs, and form, when such holes are plugged, a surface to hold grout.

The voids 16 are not built in or reduced, but are of constant cross section throughout to permit their use for finishing the joints, etc. by grouting, as will be hereinafter more fully described. Provision is made at 18 at the top of each of these voids 16 for the re-' ception of a plate 19 for closing the void, as shown in the lower part of Fig. 2.

Referring now to the floor slab 7, it will I be noted' that this slab is provided with a vertical void 20 adapted to be alined with one' of ,the voids, such as the void- 16 of the wall slab. The floor slab is also provided with voids 21 adapted to communicate with other voids such as 14 and .15 of the wall slabs and with voids such as 22 0f the floor slabs. These voids 22 of the floor slabs may run parallel either to the side or to the end tudinally extending grooves adapted to cooperate with corresponding grooves on adjacent slabs. As herein shown, each slab is provided with two external grooves of semicircular cross section and a single internal groove located therebetween and of rectangular cross section. The particular number, arrangement and form of these grooves is, however, obviously immaterial.

Referring now to the method of constructing a building from slabs of the general type as heretofore described, attention is directed to Figs. 1 and 2. In Fig. 1 the rabbeting by means of which the wall and floor slabs are anchored together, is clearly shown. In Fig. 2 I have shown the method of grouting or finishing with. cementitious material, the joints between the wall. and floor slabs. In accomplishing this step, I insert in the void 16 of the upper wall slab, a pipe. or conveyer 25 leading from reservoir 26 which may be. filled with grout or other cementitious material in a liquid state. The plate 19 is inserted at the top of the void 16 in the lower wall slab to provide a surface for receiving the cementitious material which forms a bed.

the floor slab and the'upper wall slab, as 4 well as between the floor slab and the lower wall slab. The void 20 in the floor slab will, of course, be filled duringthis operation, but if it is desired to maintain any of the other passage-ways or voids open, such for instance as that indicated at 17,21 in Fig. 3, it may be done by inserting therein a plug or sprue during the grouting operation, and thereafter withdrawing it. Heretofore, in constructing buildings of this general type, it has been necessary to do a considerable amount of trowel work or buttering by hand in an attempt to render the joints weather-proof. Experience has shown, however, that this hand operation is not only very expensive, but that it fails to produce water-tight joints. The utility of my intogether adjacent slabs,-for example, wall slabs, reference is made particularly to Fig. 5. The grooves 23 and 2 1 above described cooperate with the corresponding grooves of an adjacent slab to form the voids 23 24 A extending longitudinally of the "slabs. fierwalls, Fig.2 representing, for instance, in.

tainof these voids, as herein shown-the voids by filling them with cementitious material in the liquid state. During this filling process, I use the grouting strips 28 to prevent the escape of the cementitious material from the exterior of the interior of the wall, and

I I insert temporarily into the void 24 a plug Y or sprue 24 to keep this void open, and to also perform the function of locking the adjacent blocks in alined position during the pouring and hardening operations. After these operations are completed, the plug 2-1:

- is removed, leaving an open void which is most useful in draining olf, within the wall itself, any moisture which may, by any chance, enter the wall from the exterior. at the joint. The provision of this void 24* thus effectually prevents any of the moisture which has entered the joint from reaching the interior of the building.

The various advantages of my invention "will be apparent from the foregoing. Particular stress is, however, laid upon the fact that in the structure made as above described, all of the joints, whether between a q 23*, I utilize for securing the slabs together wall and a floor slab or between two wall 7 slabs, are weather-tight and water-proof and are made so by the expenditure of less labor than is necessary to produce the imperfect joints now in general use. The fact that I am able to provide uninterrupted passage ways through the wall and floor slabs for the conduction of-fluids and for the installation of pipes, conduits, wires, etc., is also important.

For the sake of clearness, I have described herein a single embodiment of my invention,

but it is to be understood that this embodi- .180

meaaoe inent has been chosen as an example of the many forms which my invention may take and that I do not Wish to be limited to this w particular structure since obviously many changes may be made therein, without departing from the spirit of my invention.

What I claim is:

A structure composed of floor slabs and wall slabs, the floor slabs being rabbeted on their .upper and lower surfaces adjacent the outer edges thereof, for the reception of the lower and upper edges of the upper and lower wall slabs, said upper and lower wall slabs being each provided with an open ver' voids of said wall slabs, and thereby provides an uninterrupted passage throughout the wall, for the purpose of ventilation and the like.
