BUILDING CONSTRUCTION.

Specification of Letters Patent.

" Patented Apr. 6,1915.

Application filed April 1, 1913. Serial No. 758,121.

To all whom it may concern:

Be it known that I, JEAN H. Knox, a citizen of the United States, residing at Oakland, in the county of Alameda and State of California, have invented certain new and useful Improvements in Building Construction, of which the following is a. specification.

This invention relates to concrete floor construction and has for its object the production of a concrete or plastic floor which is provided with reinforcing means for holding the floor or other member against cracking or falling apart.

Another object of this invention is the production of a plurality of metallic arches, so positioned as to allow the free circulation of air through the floor.

Another object of this invention is the production of a supporting frame for holding the concrete member in position until the same has been completed.

With these and other objects in view, this invention consists of certain novel combinations, constructions and arrangements of parts as will be hereinafter fully described and claimed.

In the accompanying drawings: Figure l is a perspective view of a portion of the concrete floor construction, showing the same in process of completion. Fig. 2 is a perspective view of the frame work and the concrete floor construction. Fig. 3 is a transverse section taken through the floor construction. Fig. 4 is atop plan View of a portion of the floor construction. Fig. 5 is a side elevation of the portion illustrated in Fig. 4. Fig. 6 is a perspective View of one form of an arch member. Fig. 7 is a perspective view of a slightly modified form of an arch.

Referring to the accompanying drawing by numerals it will be seen that the device comprises a wire web 1 which is positioned upon the frame work. A plurality of longitudinally extending rods 2 are then positioned upon this wire web, and these rods 2 are provided with a plurality of wire loops 8. The wire loops 3 are formed of a single strand of wire and are formed so as to present a substantial corrugated structure in cross section, each wire of the loop being positioned or wound around one of the rods, 2. In order to support the loops there are provided a plurality of transverse wires 4 which pass through the raised portions of the wire loops 3. A plurality of metallic arches 5 are positioned upon the wire 1 and between the longitudinally extending rods 2, theend of each arch abutting against the adjacent arch.

In this manner the air may freely circulate through the fioor by means of the arch members. The transverse wires 4 which support the wire loops 3 pass above the arches 5 and in this manner hold the same securely in place. After the metal reinforcing members have been positioned, as above device so as to extend evenly upon its upper surface, as illustrated at 7 in Fig. 1. Another reinforcing wire web is placed upon this layer of cement at which time a finishing layer 9 of cement is placed upon the wire web 8 for forming the upper surface of the floor. The device may also be used in combination with the metallic arch 10 having laterally extending flanges 11. When this form of arch is used, the longitudinally extending rods 2 for securely holding the arch members in position, prior to pouring the cement thereon. It will further be seen that a finishing coat 12 of plaster or other cement may be placed upon the lower portion of the wire web 1 for forming a substantial even surface for a ceiling or other member upon the lower part of the floor.

In order to support this device while the same is being constructed there are provided a plurality of standards 13 which support upon their upper end the cross-beams14, these cross-beams being provided with transverse beams 15 uponwhich the web frame 16 is positioned. After the supporting frame has been formed in this manner, the wire web 1 is then placed thereon, and the reinforcing members placed thereon, as above described. After the structure has dried and it is desired to move the frame, the wedge blocks 17 may be struck so as to remove the same from the lower part of the standards 13 at which time the framework will fall and the floor will be completed.

From the foregoing description it will be seen that an eflicient floor member has been produced which may be used in combination with sewers, vaults, and other places in which a reinforced concrete structure is used.

Having thus described the invention, what is claimed as new, is

A floor construction comprising a plurality of longitudinally extending rods, a

the flanges 11 fit under described, a quantlty of cement 6 is then poured upon the plurality of Wire loops positioned upon said longitudinally extending rods, said loops bent acutely to form pockets at their upper portions, transverse Wires passing through said loops and resting Within said pockets for retaining said loops in a vertical position, said transverse Wires being held against lateral movement Within said loops by resting Within said pockets, arched plates positioned between said longitudinally extending rods, said rods adapted to hold said plates in their correct position, and plastic material covering all of said beams and Wires and supported upon said arched plates.

In testimony whereof I afiix my signature in the presence of tWo Witnesses.
