'REENFORCED-CONCRETE VfW'IAIiL SECTION Applicgtionled August 1, '1924. Serial No. 729,575.

To all whom, t may concern "Be it known that L'CHARLES GARRILLON, a citizen of the United States, and a resident oft the city of St. Louis and State of Missouri, have invented `a new and useful Improvement in Reenforced-Concrete Wall Sections, of which the following is a full, clear, and exact description.

vMy invention relates to improvements in reenforced concrete wall sections, and it consists in the combinations, constructions, and arrangements herein described and claimed.

An object .of my invention is to provide a `concrete wall section by means of which an entire section of the building may be `manufactured in one piece. Heretofore blocks have `been manufactured which are provided with air spaces, but it has not been practical to manufacture such blocks in large sections. My present invention embodies a means for constructing entire sections which are durable enough to permit thefmanipulation -of the entire section, as

r in Aerecting `the section.

A further object .of my `invention is to provide a novel Vmeans .for obtaining an air space between the walls of the section without sacrificing strength.

Ak further object of my invention is to provide a reenforced .concrete Wall section, having .an air space, Vwhich obviates the use of special forms :and the various means for holding the reenforcing elements while the sections .are constructed.

Other objects and advantages will appear in` the following specification, and the novel features of the invention will be particularly pointed out in the appended claims.

My invention is illustrated in the accompanying drawings, forming part of this application, in which- Figure 1 is a sectional view of the wall section with the sand core and the side walls of the supporting form removed,

Figure 2 is a side elevation of one of the sections in a vertical position and partially broken away, and

Figure 3 is a sectional view of a. modified form of my invention.

In carrying out my invention I make use of a layer of concrete 3, which in the or dinary case is approximately one inch thick. A metal screen 4 isdisposed on this layer of concrete 3. The general appearance of this screen is indicated in Figure 2fand will be recognized as the ordinary type of wire lath 1n common use. The screen 1s bent upwardly at keither end as shown at 5 and ,screenv immediately after the application of the screen to the still wet layer 3.

A kplurality of v,angular convoluted iron rods `8 are provided which are fashioned so that each rod .has parallel portions 9 and 10 arranged staggered relation lone with another. The portions 9 are in alignment and the `portions l0 are in alignment one with another. The rod 8 is constructed of suiicient diameter to lend the necessary strength vto Vthe completed section, and if this vsection is to be a large one the rod should be of a diameter proportional to the required strength of the screen. The convoluted rods 8 are Yspaced in parallel relation one with another and are partially imbedded in the `concrete layer 7 to a point in close proximity with the screen 4. As will be noted from Figure l, -the :parallel portions 10 are imbedded in the layer 7, while the lportions I9 are disposed at `ai distance yfrom the upper surface 11 of the layer 7.

A layer of concrete is then formed in which the portions 9 are imbedded and in which the extremities 6 of the portions 5 oi the screen 4 are imbedded.

The layer 13 is at a predetermined spaced distance from the united layers 3 and 7, thus providing an air space between the parallel wall portions of the screen.

From the foregoing description of the various parts of the device the operation thereof may be readily understood. It would be well to explain at this time that the sections formed may be of any desired shape. In Figure 2 I have shown a section which may be used as an end or side wall of a garage or small house. Tapered portions 14 are provided so as to accom modate the rooiI construction.

A reenforced concrete wall section constructed in accordance with my invention is exceedingly strong, since the rods 8 engage with each of the spaced apart concrete Walls 3 7 and 13, and therefore there is little or no possibility of breakage through manipulationexercised with ordinary care. Heretofore concrete wall sections have necessarily been constructed 'for small areas alone. This has been necessary since the construction employed up to the present timeV has consisted in the use of individual reenforcing members in place of relatively long convoluted rods 8.

The laterally bent portions 5 of the screen l not only serve to strengthen the sections at their opposite edges, but also greatly facilitate the securingl of the Wall sections one to another as in the intersectionof two sections to form a corner. The mortar or cement used to secure the two sections may be imbedded directly in the portions 5 or the screen Ll, thereby insuring the secure and permanent fixture of the screens one to another. Y' r The provision of the dead air space between the Walls of the sections serves as a most important insulatingfmea-ns for confiningheat Within the building constructed of theisections, and for keeping the building cool in the summer time against the penetration ofheat from Without. Y

It is obvious that a metal screen similar tothe screen 4 may be used in the Wall sectien 13, shown in Figure l, this screen being disposed adjacent to the parallel portions 9 of the convoluted iron rods 8 in a manner similar to the screen 4 in the companion Wall portion, Without departing from the spirit of the invention. In fact, when strong construction is desired, it is preferable to use two screen portions, as shown in Figure 3. In this ligure the upper portion 123i is provided With a screen; la imbedded therein, similar to the screen l in the section 3. This screen portion lies adjacent to the parallel portions 9 or' the rods 8.

l claim:

l. A reenforced concrete wall section comprising a` pair or concrete Walls spaced apart from one another, connecting members for securely holding said Walls in spaced apart relation, 'consisting of angular convoluted metal rods having parallel portions in Ystaggered relation to: one another, one set of said parallel portions being'embedded in one of said Walls, and the other set being embedded in the opposite Wall, and a metal screen dis posed in one of said Walls and parallel thereto, said screen having two of its outermost edges bent laterally to extend into the opposite Wall adjacent the edge-s of the section.

2. A reenrorced concrete Wall section comprising a pair of concrete Walls spaced apart from:V one another, connecting members for securely holding said walls in spaced apart relation, consisting Yof convoluted metal rods having parallel portions in staggered relation'to one another, one set of said parallel portions being embedded in one of said Walls and the other set being embedded in the opposite Wall, and a metal screen disposed in each of said Wall portions adjacent to the metal rods, said screens'being parallel with the faces or' the Wall.

3. A reenforcing concrete Wall section comprising a pair of concrete walls spaced apart from one another, connecting members for securely holdin said Walls in spaced apart relation, cons1sting of angular convoluted metal rods having parallel portions in staggered relation to one another, said set of parallel portions being imbedded in one of said Walls and the other set of parallel portions being imbedded in the opposite Wall, and a reenforcing screen disposed in one Yolf said Wall sections and being bent at its ends transversely to the plane of said Wall section, and extending toward and embedded into thegopposite Wall section.
