HORA'IIO LEONARD BARRAOLOUGI-I, OF LONDON, ENGLAND.
CONSTRUCTION OF REINFORCED-CONCRETE FLOORS.
Application filed July 17, 1919.
To all whom it may concern:
Be it known that I, HORATIO LEONARD BARRACLOUGH, a subject of the King of England, residing at Eaton vVharf, 135 Grosvenor road, S. W. 1, London, England, (whose post-office address is Eaton WVharf, 135 Grosvenor road, S. W. 1, London, England,) have invented certain new and useful Improvements in the Construction of Reinforced-Concrete Floors, of which the following is a specification.
This invention which relates to the construction of reinforced concrete fioors has for its object to avoid the necessity of centering the floor.
According to this invention the floor is constructed of a plurality of reinforced concrete inverted T-shaped girders or beams, provided toward the center with small flanges on the tops of their webs and widening toward the center, laid in position contiguously with a filling of concrete between the beams and with or without inverted pots, filler blocks, or other void forming means, between them.
The girders or beams are cast with reinforcements at the works, the tops or upper parts of their webs being made toward the center with flanges of increasing width toward the center to take up the extra strain of the compression at the center of the fiooring. The girders or beams can be all placed in position and the inverted pots or other void forming means, when such are used, can be slid from the ends of the floor between the beams or girders under the gradually widening tops or upper parts; or the beams and pots, or other void forming means, may be laid down alternately. When all are in position the spaces between the girders and the pots or void forming means, and above the pots or void forming means, are filled with concrete in situ. If required the fioor may be reinforced longitudinally between the girders and the pots or void forming means.
In the accompanying drawings Figures 1 and 2 are longitudinal and transverse sections taken respectively on the lines 11 and 22 in Fig. 3 with the filling in concrete omitted; and
Fig. 3 is a part plan of a floor constructed according to this invention.
Fig. 4 shows in end elevation a modification of the beam or girder and Specification of Letters Patent.
Patented Jan. 20, 1920.
Serial No. 311,674.
Fig. 5 is a transverse section of three of such girders arranged to form a floor.
The girders or beams A are cast at the works with reinforcing rods A running through their webs A said rods being connected by bridles A in the usual way.
In constructing the floor, the girders or beams A are laid close against each other side by side on supports B. Pots or other vessels D to form voids (if used) are then placed equidistantly between the girders over the joints at the meeting line of the feet or bases A of the girders, thereby preventing the grout running through and saving waste. Concrete is then filled or cast in between the girders, or between the pots and girders and above the pots, and if necessary above the girders also, to make the floor E. As previously stated, longitudinal reinforcing rods may if required be placed between the pots and the girders, and preferably at or near to the feet or bases of the girders.
As shown in Figs. 2 and 3, the tops A of the webs A of the girders or beams are made toward the center with small flanges A increasing in width toward the center of the flooring to take up the compression.
Instead of using pots or vessels such as shown at D in Figs. 1 to 3, I may form or provide the inverted T-shaped girders or beams A used in the construction of the floor with a corresponding fillet or fillets or projection or projections A as shown in Figs. 4; and 5, on each side of the web A between the base A of the girder or beam and the top A and for the full length from end to end of the girder or beam, which fillets or projections A serve as ledges or shelves to receive the ends of metallic, reinforced concrete, or other plates to form base plates or tiles F or foundation plates for the concrete filled in in situ.
WVhen the girders and beams are laid in position to form the floor, the plates or tiles F are laid upon the fillets or projections A as shown in Fig. 5 andthe concrete is filled in on the top, the spaces G underneath the plates or tiles being left void.
Having fully described my invention, what I claim and desire to secure by Letters Patent is 1. A reinforced concrete floor comprising a plurality of previously cast reinforced concrete inverted T-shaped girders or beams, having the tops of their webs provided toward the center of the longitudinal extent of the girder or beams with small flanges of increasing width toward the said center and vtapering off to nothing at each end of the beani, said girders being laid close against each other on supports, and a filling of concrete cast situbetween them.
2. A reinforced concrete floor comprising a plurality of previously cast reinforced concrete inverted T-shaped girders or beams, having the tops of their webs provided toward the center of the longitudinal extent of the girder or beams with small flanges of increasing width toward the said center and tapering off to nothing at each end of the beam, a fillet or projection in a corresponding position on each side of the web of every girder, and extending for the full length from end to end of the girder, all the girders being laid side by side close against each other on supports, plates or tiles laid upon the fillets or projections, and a filling of concrete cast in situ between the girders and the plates or tiles.
In testimony whereof I have hereunto set my hand in presence of two subscribing witnesses.
HORATIO LEONARD BARRACLOUGH.
