WENZEL J. DVORAK, OF SUNSET HEIGHTS TEXAS.

CONCRETE BUILDING CONSTRUCTION.

Application filed March 26, 1923. Serial No. 627.609.

To all whom it my came a.-

Be it known that I, WENZEL J. DVORAK, a citizen of Czechoslovakia, residing at Sunset Heights, in the county of Harris and State of Texas, have invented certain new and useful Improvements in Concrete Building Constructions, of which the following is a specification.

This invention relates to new and useful improvements in concrete building construction.

One object of the invention is to provide a construction of the character described whose parts are precast, previous to erection, said parts being provided with suitable reinforcing rods which project to form loops by means of which the parts may be tied together during the process of erection.

With the above and other objects in view the invention has particular relation to certain novelfeatures of construction, arrangement of parts, and use, an example of which is given in this specification, and illustrated in the accompanying drawings, wherein:-

Figure 1 shows a fragmentary horizontal sectional view of the construction.

Figure 2 shows a fragmentary vertical section view;

In the drawings the numerals 1 and 2 designate the vertical corner beamswhich are of a suitable contour to fit closely together, and the numeral 3' designates a wall colunm. These columns are mounted on a suitable foundation as 4, and when a story of the construction is completed a suitable cap plate as 5 is poured, this ca'p plate forming a support. for an additional story. In the cap plate of the upper story bolts as 6 are embedded to receive the wooden strip 7 which is secured in place by the nuts 8. This wooden strip is provided for nailing the rafters or other roof support to the structure. The

columns

1, 2 and 3 have suitable vertical reinforcing rods as 9 and horizontally arranged reinforcing rods as 10, 10, 11, 11, 12, 12, and 13 which project out forming loops or ties, as illustrated in Figure 1. The walls are composed of

outer wall slabs

14, 14 and

inner wall slabs

15, 15 spaced apart and reinforced with the reinforcing rods 16 and 17 respectively. These reinforcing rods of the wall slabs project out at the ends forming the loops 10', 10', 11', 11312312, and 13', 13', which overlap the corresponding loops 10, 11, 12

and 13, respectively, and the parts are interlocked or tied together by the

corresponding tie rods

18, 18, 19,20, 20, and 21, 21, and when erected in position concrete in plastic state is poured in between the adjacent walls to embed said overlapping loops and looking rods in the material of the wall and when this concrete is hardened it will form a substantially monolithic structure. The reinforcing rods 9 have their lower ends embedded in the foundation as well as in the cap plate of the wall, thus tying the parts together and forming a very strong construction. The wallslabs 14; and 15 are mounted one upon the other, as shown in Figure 2. These slabs are preferably about two feet in width and of the required length and thickness and when mounted in place with their ends anchored to the columns of the framework, as described, and as shown in Figures 1 and 2they form a smooth and durable wall substantially hollow throughout thus providing a building whose interior is not suddenly afi'ected by variations in the outside temperature.

What I claim is 1. A concrete construction composed of a base, precast concrete columns mounted on said base and forming corner columns and wall columns, vertical reinforcing rods embedded in said columns whose lower ends 7 project beyond the columns and are em bedded in said base, precast concrete wall slabs disposed one above the other forming outer and inner walls horizontally arranged, reinforcing rods in said projectingv columns and slabs which are formed into projecting loops which project from adjacent parts of the columns and slabs and overlap, looking rods projecting through said loops and locking them together, the upper ends of the vertical reinforcing rods of said columns projecting beyond the columns, and a cap plate molded onto the top of the complete wall of said construction, the said projecting upper ends of said rods being embedded in said cap plate.

2.'A c0nc1ete construction composed of a base, precast vertical corner columns, and precast vertical wall columns, said corner columns being formed of vertical sections formed to complement each other, and said rods in said respective columns which project out, forming loops or ties, and loops projecting from the respective sections of the wall columns and, over-lapping, outer wall slabs and inner wall slabs spaced apart, lon 'tudinal reinforcing rods embedded in sai slabs and formed with projecting end loops which overlap the corresponding 100 s of the horizontal reinforcing rods of t e columns, vertical tie rods inserted throu 11 said respective overlapping loops and 100 ing said parts together, said vertical reinforcing. rods projecting up above said columns, and a cap plate moulded onto the top of the complete wall of the construction, 15

said projecting upper ends of said rods being embedded in said cap plate.
