' EDWIN ALLBRIGHT, F ATLANTIC, MASSACHUSETTS, ASSIGNOR TO ADAMS-POND COMPANY, INC., OF BOSTON, MASSACHUSETTS, A CORPORATION OF MASSACHUSETTS.
CONCRETE CONSTRUCTION.
To all whom it may concern Be it known that I, EDWIN F. ALLBRIGHT,
a citizen of the United States, residing at Atlantic, in the county of Norfolk and State of Massachusetts, have invented an Imp provement in Concrete Construction, of which the following, description, in connection with the accompanying drawings, is a specification, like characters on the drawings representing like parts.
The invention to be hereinafter described relates to concrete construction, and is an improvement upon the construction shown,
described and claimed in Letters Patent N o.
1,307,031, granted to me June 17, 1919.
The concrete construction of said patent comprises a continuous concrete slab having solid panels resting on columns, and bays between said solid panels having at their under sides transversely extending ribs with domes or recesses distributed therein to the solid panels. In the production of this construction, domed pans or forms are employed, having outwardly extending flanges, the pans being adapted to be arranged in rows with the outwardly extending flanges thereof in engagement to..determin'e the spacing thereof. The pans are supported by shoring comprising stringers on which the flanges of the pansrest, beams supporting the stringers, and posts disposed at appropriate intervals to support the beams.
The concrete is poured into spaces between the pans, and in suflicient amount above the. tops of the pans to furnish a concrete slab of the depth required.
To reinforce the slab, crossing series of reinforcing members are provided arranged in pairs. ,Certain of said members have portions located in the lower portions of the ribs of the bays, portions inclining upwardly at the edges of the bays, and end portions in the upper surface portions of the margins surrounding the bays. Others of said members have portions in the lower portions of the ribs of the bays and continue without deflection into the margins surrounding the bays. .The arrangement of these reinforcing members is such that the members of adjacent bays overlap in the margins surrounding the bays.
This is a good reinforcing system for the purposes, but many of the reinforcing members must be specially bent before being placed, and care must be taken that they Specification of Letters Patent. Patentedsept, 21, 192() Application filed July so, 1919. Serial No. 314,347.
- are bent at the proper points to conform to the areas of the bays. Also, it is difficult properly to locate and support these bent members before the concrete is placed, and to maintain these members in their proper positions while the concrete is being placed.
The purpose of the present invention, therefore, is to provide a'cheaper, simpler reinforcing system of members which may be readily located in their proper position before and during placing of the concrete,-
and which will furnish efiicient reinforcement for the concrete. In carrying the invention into practical efl'ect, straight reinforcing members may be employed throughout, thereby eliminating the necessity for employment of special forms of reinforc- 22 of Fig. 1 after the concrete'is placed,
Fig. 3 is a vertical section taken on line 33 of Fig. 1 after the concrete is placed;
Fig. 4 is a perspective view of a system of reinforcing rodsor members for a portion of the slab;
Fig. 5 is a perspective view of a detail to be referred to; and a Fig. 6 is a perspective view of one of the pans or forms.
Referring to the drawings, and more particularly to Fig. l, to produce the domes or recesses in the under side of the bays, pans or forms 1 are provided having outwardly extending flanges 3, the pans or forms being assembled with their flanges engaging one another to determine the spacing thereof.
'Suitable means may be provided to support the pans or forms, in the present instance, comprising stringers 5 on which the flanges of the pans or forms rest, beams 7 extending transversely to and supporting the stringers, and posts 9'disposed at suitable intervals to support the beams. Suitable forms 11 are also provided for the produc-.
tion of solid panels above the columns.
The system of reinforcing members for the concrete slab, in the present instance of the invention, comprises crossing series of reinforcing rods or members 13, preferably arranged in pairs and located in the lower A portions of the bays between the solid panvided, preferably in pairs and located in jacent bays.
the lower portions of. the ribs extending from panel to panel in the margins sur-. and located between'adrounding the bays,
These rods or members may terminate substantially at the edges of the solid panels, and preferably certain ofthese rods .or members extend somewhat beyond others into .the solid panels.
. The series of rods or members 13 and.15 described will ifurnish the necessary reinforcement for the lower surface portion of 40., -tions of the margins surrounding the bays. Suitable means maybe rovlded to support the slab, which experiences tension stresses. A series of relatively short rods or members 17 may be provided, preferably arranged in pairsin the upper surface portions of thenmargins, surrounding the bays of the slab. These rods or members may extend transversely to the rods or members 15, and preferably certain of .said rods or members may project beyondothers into the adjacent bays. These relatively short rods or members will furnish the necessary tension reinforcement for the upper surface portlf'ese relatively short reinforcement rods or members the proper distance above the flanges. of the pans orforms. This means, in the present instance of the invention, comprises briquets 19 of concrete or other'suitable material which may be suitably formed tox-fitbetween and rest on adjacent pans or forms. The short rods or members may rest on these briquets, and be supported thereby at the proper elevation above the flanges of the pans or forms, and these briquets ma remain in the concrete and form apart o the final constructlon.
Crosslngserles of reinforc ng rods or members 21 may be provided in the u per surface portions of the solid panels a ove the columns, and preferably may extend somewhat beyond the edgesof said solid anels into'the bays and margins surround- -mg the solid panels.
In some instances it may be desirable to I iprovide further reinforcement at the juncture of the bays with the solidqpanels to said rods or.members shall be inclosed in the concrete. Supporting devices for reinforcing rods or members are wellknown in the art, and therefore, it is unnecessary to show the same herein.
After the system of reinforcing rods or members has been locatedas described, the concrete may be poured around the pans or forms and on the forms for the solid panels to the depth required. After the concrete has stood three or four days, it will have hardened sufficiently to permit the majority of the pans or forms to be removed. Gertain of the'pans or forms at suitable intervals may remain in place and may continue to be supported by posts to furnish the necessary support 'for the slab until ithas fi-. nally hardened.
The final construction Will comprise columns 23 supporting a slab comprising solid panels 25 resting on the columns, bays 27 between the solid panels, and margins 29 between adjacent bays. The domes or recesses will be formed on the under sides of the bays or margins. The system of reinforcing rods or members and the briquets will be inclosed in the concrete, and the system -will furnish the requisite tension reinforcementfor the slab throughout,
By my invention a simple and efiicient re-,
inforcing system is provided for the slab, the rods or members may be of standard construction, and sinceall of the rods are straight, it is merely necessary to cut the same into lengths required without the necessity for bending or otherwise specially shaping the same. Also, by this system important economies are obtained in the amount of reinforcement required. and in the time and labor required to position the same in readiness to have the concrete placed about the system] It will be understood that the invention is not limited to the specific embodiment shown, and that various deviations may be made therefrom without departing from the spirit and scope of the appended claims.
