UNITED STATES WALTER E. CREW, 0F MEMPHIS, TENNESSEE.

CON CRETE-SLAB CONSTRUCTION.

Specification of Letters Patent. Patented Dec. Y14:, 1920.

Application filed March 22, 1920. Serial No. 367,904.

To all 'whom t may concern:

Be it known that I, WALTER E. CREW, a citizen of the 'United States, residing in Memphis, county of Shelby, State of Tennessee, have invented certain new and useful Improvements in Concrete-Slab Construction, of which the following is a full, clear, and exact description, such as will enable others skilled in the art to make and use the same.

My invention relates especially to improvements in the methods of joining two or more concrete slabs, whereby two adjacent slabs may have at the time of pouring a metal plate or hinge embedded in their contiguous edges, whereby a self bracing structure or wall may be erected by setting up two or more such slabs at an angle to each other. These slabs may be cast in any position, preferably on a horizontal form so that one surface will be given 'a smooth finish the form itself, and the other surface may be finished by hand in any desired manner. The slabs may then be erected with the various sections at any desired angle to each other, and when so erected each slab braces the other rigidly.

The objects of my invention are to provide means whereby the casting of a number of sections of slab may be done expeditiously and at low cost with simple forms, and the slabs so cast may then be erected at any desired angle relative to each other, and when soV erected 'will mutually brace each other. I accomplish these objects as will be fully hereinafter set out in the drawings, specifications and plans.

In the drawings:

Figure 1 is a perspective view showing method of casting the slabs.

Fig.-2 is an end elevation showing two adjacent slabs with a modified type of edge and connection.

Fig. 8 is a similarend elevation` showing a second modification of the shape of the edges of the slabs.

Fig. 4 is a perspective sketch showing the slabs'of Fig. 2 erected.

Fig. 5 is Va perspective sketch showing the slab shown in Fig. 1 erected vertically.

Fig. 6 is'a perspective sketch showing the slab shown in Fig. 3 erected. Y

Fig. `7 is a plan view showing a third modification of the edge ofthe slab, as it would appear when erected. Y

sired to form the upper bevel. These slabsV are shown with reinforcing rods 6, which may be omitted vif desired as they have noA essential bearing on the invention. The two slabs and 2 are connected by a metal platev 7, which preferably, has lugs 8 punchedrv out therefrom or other type of deformation not shown, to securely embed it and anchor it into the slabs. This plate is pref` erably a continuous metal plate of soft iron, which can be bent as a hinge during the erection of the slabs and when so bent will securely hold the two slabs in relative alinement with each other..

In Fig. 2 I have shown two sections of slab 9 and 10, havingthe upper halves 11 and 12 ofthe adjacent slab edges beveled and having the lower halves 13, and 14 at right angles to the face of the slab. In this case, as in the preceding case, the metal connection 15 is in the center of the slab. In this case, however, the connection shown is a series of plain reinforcing bars instead of a continuous plate. It is of course evident Y that these bars may be deformed bars, or

twisted bars, instead ofthe plain bars shown, if sufficient adhesion is not obtained by the plain bars or if more adhesion is thought necessary.

In 16 and. 17 beveled on one side only withthe connecting plate 18 at the point of the bevel as in the preceding cases. In this particular case I have shown the angle of the bevel on each of the slabs as degrees with the face of theslab. But this bevel may be-varied, as may the other bevels, it being properly varied to conform to the angle at which the slabs may be designed Vto be erected. It will be understood that mately at Vthe intersection of the bevels.

Asok

. In Fig. f1, the slabs 9, and 1'0, are the slabs 9 and 10 of Fig. 2 erected, With the slab 10"L in a horizontal position and slab 9a in a vertical position. VIn this case the edges 13aL andlL should be embedded in a concrete footing 19.

In Fig. 5, 1, and 2a, indicate the slabs 1 and `2 linFig. 1 in an erected position with both slabs vertical andl resting on aufooting 20 especially prepared for same.

n Fig. 16a and 17a represent the slabs 16an'df1f1of Fig. Savith an additional slab 21, Inot shown in Fig. 8, similarly connected. These slabs are shown erected on a concrete foundation 22. VSlabs 16a and 21 forming -the inclinedsides andthe slabs 17EL the horizfontaltop of a culvert, or similar construction.

'"'In., I show two slabs 23 and 24 which have been cast with square edges properly s ,aced apartand Which are then erected so t at the corners 25 and 26 of these slabs just meet. 27 isla pilaster covering these corners ,andiinishing same. 28 and 29 are reinforcing rods which may be used to reinforce andanchor the pilaster so that it Will function as a part ofthe construction.

` It will be distinctly understood that while I have shown a number of forms for the edges ofthe c oupled slabs that the form of these edgesmay vary from any'of those shcvvn, the essential feature being that'the adjacent edges are connected by a bendable metal construction which will preserve the alinement of the slabs While they are being erected and Which Will permit the slabs being erected With their surfaces at varying angles to each other. I have shown the bevel on the slabs such that When the slabs are erected the bevel surfaces Yjoin closely.

It is preferable 'that sufficient space shall be left between these surfaces to permit a mortar joint and it is not necessary thatthe bevels should conform exactly Vto the angle that the exterior surfaces of the slabs havewhen erected, as it is entirely possiblel to leave a Wedge shape mortar joint at the angle. .This is clearly illustrated, hoiveve'r, inFig. 7 in which the entire joint is formed ofl concrete and in which for all practical purposes the edges of the slabs do not touch.

It is also evident that the metal connection which I have described in one case as a plate and in another lcase as a number of rods, could also be a number of flat plates of narrow Width either close together or spaced apart as the rods would necessarily be and-in construing the claims it is expressly understood that such latitude shall be allovved.

Having now fully described my invention, what I claim and desire to secure by Letters Patent in the Unitedl States is l. A self bracing structure, comprising concrete slabs cast With edges adj acent, and havingbendable metal connections embedded during the casting of the slabs and lextended from the adjacent edges thereof to connect theV same, and bent during erection to adjustk the angle of the slabs relatively to each other, to thereby cause the said slabs to rigidly brace each other.

2. A self bracing structure, comprising concrete slabs cast with edges adjacent, and having a bendable metal plate embedded during the casting of the slabs and vextended from the adjacent edgesV thereof to connect the same, and bent during erection to adjust the angle of the slabs relatively to each other, tothereby cause the said slabs to rigidly brace each other.

3. self bracing structure, comprising concreteA slabs cast with beveled edges adjacent, and having bendable metal connections embedded during the casting of the slabs and extended from the adjacent edges thereof to connect the same, Vand bent during erection to adjust the angle of the slabs relatively to each other, to thereby cause the said slabs to rigidly brace each other.

et, A. self bracing structure, comprising' concrete slabs cast With edges adjacent and having bendable metal connections, embedded during the casting of the slabs and extended from the adjacent edges thereof to connect the same, and bent during erection to adjust the angle of the slabs relatively to each other, lto thereby `cause the said slabs to rigidly brace' each other, and a concrete pilaster cast in place and anchored to the said slab edges, substantially as shown and described.

`In testimony whereof, I have hereunto subscribed my name.
