11 Claims.

.This invention relates to flooring for bridges and other structures which requires that it shall be self-supporting under heavy loads.

The object or" the invention is to provide a stron and substantial flooring adapted to stand heavy loads and resist shocks, jars and vibrations to which bridges and other structures are subjected.

.Another object of the invention is to provide a flooring structure in which a plurality of T- irons having their heads arranged in parallel relation edge to edge and in contact and their webs upstanding are tied together by cross-bars ofncvel construction to form a strong, substantial rigid structure.

And a further object of the invention is to provide a flooring structure which can be made in sections and assembled on the job for filling with a concrete or other mixture.

In the accompanying drawing illustrating a selected embodiment of the invention,

Fig. 1 is a section of the flooring.

Fig. 2 is a sectional View through the T-irons.

Fig. 3 is a plan view of a cross-bar showing how it is cut to form the legs and also showing the legs in broken lines in final position.

Fig. 4 is a detail view of a portion of a T-iron.

Referring to the drawing, each T-iron has a head 5 and a web 6. These T-irons are arranged with their webs upstanding and their heads in parallel relation edge to edge and in contact. The flooring structure may be made on the job or sections may be prepared and laid edge to edge on the job, each section comprising a plurality of T-irons of suitable length tied together by the cross-bars and ready to be filled with the concrete or other mixture 7.

Each cross-bar comprises a metal strip 8 which is cut angularly at spaced intervals as indicated by 9 and these out parts are then bent downward in pairs to form legs 10. The legs are spaced apart where they join to the strip and their lower ends contact forming a triangular space 11 between each pair of legs. The outer edge of each leg tapers from the top and from the bottom to a point about midway of the length of the leg which thereby increases the width from each end to its middle. The cross-bar is reduced in width at 12 and the webs of the T-irons are notched at 13 to receive these reduced portions so that the top edge of the cross-bars will lie 'tions 14 at the sides of the webs and enlarges the on the cross-bars are arranged in alternate channels 17 between the webs of the T-irons and I rrange the cross-bars'so that the legs on one cross-bar will be in staggered relation to the legs on the adjacent cross-bar. A section of the 11001"- ing as shown in Fig.1 will have a leg 10 on one end of each cross-bar and this leg will be welded at its lower end to the head of the T'-iron. I prefer to weld the cross-bar at its upper end to the web at 18 to assist in holding the parts of the section rigidly together.

After the parts of the sections are assembled on the job, the concrete 7 is poured into the spaces between the webs of the T-irons andrcompletely fills these spaces flush with the top edges of the webs and the cross-bars to form a continuous smooth surface. The cross-bars anchor the T- irons together with the edges of their heads in close contact and form a solid rigid structure which will hold the filling and provide a strong and substantial flooring. The cross-bars not only serve to anchor the T-irons together but they also constitute a reenforce for the filling.

I have shown and described a simple embodiment of the invention adapted for commercial use as a bridge floor structure and flooring but it may be necessary or desirable to vary the form, construction and arrangement of parts for other uses or to satisfy diiierent conditions and I reserve the right to make such changes within the scope of the following claims:

I claim:

1. A flooring structure comprising a plurality of T-irons arranged with their heads inparallel relation edge to edge and in contact with their webs upstanding, and cross-bars engaged with the upper edges of the webs and having integral legs extending downward and secured to said heads.

2. A flooring structure comprising a plurality of T-irons arranged with their heads in parallel relation edge to edge and in contact and their webs upstanding, and cross-bars engaged with the upper edges of the webs and having integral legs extending downward and secured together at their lower ends and to said heads.

3. A flooring structure comprising a plurality of T-irons arranged with their heads in parallel relation edge to edge and in contact and their webs upstanding, and cross-bars engaged with the upper edges of the webs and having integral legs extending downward and secured together at their lower ends and to said heads at the joint therebetween.

4. A flooring structure comprising a plurality of T-irons arranged with their heads in parallel relation edge to edge and in contact and their webs upstanding, and cross-bars engaged with the webs and having projections extending downward from the cross-bars into the channels between said webs.

5. A flooring structure comprising a plurality of T-irons arranged with their heads in parallel relation edge to edge and in contact and their webs upstanding, and cross-bars engaged with the webs and having parts thereof bent downward into the channels between the webs.

6. A flooring structure comprising a plurality of T-irons arranged with their heads in parallel relation edge to edge and in contact and their webs upstanding, and cross-bars engaged with the upper edges of the webs and having integral legs extending downward therefrom in pairs in the channels between the webs.

7. A flooring structure comprising a plurality of T-irons arranged with their heads in parallel relation edge to edge and in contact and their webs upstanding, and cross-bars engaged with the upper edges of the Webs and having integral legs extending downward therefrom in pairs in the channels between the webs and having their lower ends secured together.

8. A flooring structure comprising a plurality of T-irons arranged with their heads in parallel relation edge to edge and in contact and their webs upstanding, and cross-bars engaged with the upper edges of the webs and having integral legs extending downward therefrom in pairs in the channels between the webs and having their lower ends secured together and to said heads.

9. A flooring structure comprising a plurality of T-irons arranged with their heads in parallel relation edge to edge and in contact and their webs upstanding, and cross-bars engaged with the upper edge of the webs and with said heads in the channels between the webs.

10. A flooring structure comprising a plurality of T-irons arranged with their heads in parallel relation edge to edge and in contact and their webs upstanding, and cross-bars engaged with the upper edges of the webs and having integral legs extending downward and secured to said heads, said legs being enlarged transversely between their ends.

-11. A flooring structure comprising a plurality of T-irons arranged with their heads in parallel relation edge to edge and in contact and their webs upstanding, and cross-bars reduced transversely at spaced intervals and engaged at their reduced parts with the upper edges of the webs and having projections between said reduced parts extending downward in the channels between the webs.
