Abstract
The utility model provides a two-way support frame of superimposed sheet and by its prestressing force superimposed sheet that constitutes belongs to building superimposed sheet application technique field, and two-way support frame includes two supports or two trusss or a support and a truss, two simple supports or two simple trusss or a support and a truss are perpendicular or are close vertical layout. The prestressed composite slab comprises a composite slab body and a bidirectional support frame arranged in the composite slab body, wherein the length and the number of the transverse support and the longitudinal support in the bidirectional support frame are determined according to the design requirement of the composite slab. The utility model discloses a two-way support frame of superimposed sheet and by its prestressing force superimposed sheet that constitutes, owing to all arranged support or truss structure on superimposed sheet is vertical and horizontal direction, so both satisfied the fore-and-aft intensity requirement of superimposed sheet, satisfied the horizontal intensity requirement of superimposed sheet again, not only be applicable to the veneer, still be applicable to the double plate.
Description
Technical Field
The utility model relates to a superimposed sheet for building, specifically speaking are two-way support frame of superimposed sheet and by its prestressing force superimposed sheet that constitutes.
Background
The laminated slab is an assembled integral floor slab formed by laminating prefabricated slabs and cast-in-place reinforced concrete layers. The laminated slab has good integrity, the upper surface and the lower surface of the slab are smooth, the decoration of a finish coat is convenient, and the laminated slab is suitable for high-rise buildings and large-bay buildings with higher requirements on the integral rigidity.
The span of the laminated slab is generally 4-6 m, and the maximum span can reach 9 m. The laminated slab supports in the prior art are all one-way supports, and when the width of the laminated slab is increased to a certain degree, if the one-way supports are still adopted, the transverse strength of the laminated slab cannot meet the strength requirement.
Disclosure of Invention
The technical task of the utility model is to solve the not enough of prior art, provide a two-way support frame of superimposed sheet and by its prestressing force superimposed sheet that constitutes.
The utility model provides a technical scheme that its technical problem adopted is:
a two-way support frame for laminated slabs at least comprises two supports or two trusses or a support and a truss, wherein the two supports or the two trusses or the support and the truss are arranged vertically or nearly vertically.
Further, the pressure lever of the bracket is made of one of strip steel, steel pipe, C-shaped steel, groove-shaped steel or round steel.
Further, the upper chord member and the lower chord member of the truss are made of one of strip steel, steel pipes, C-shaped steel, channel steel or round steel.
The prestressed composite slab formed by the bidirectional support frame for the composite slab comprises a composite slab body and the bidirectional support frame arranged in the composite slab body, wherein the length and the number of the transverse support and the longitudinal support in the bidirectional support frame are determined according to the design requirement of the composite slab.
The utility model discloses a superimposed sheet two-way support frame and by its produced beneficial effect of prestressing force superimposed sheet of constitution compare with prior art is:
the utility model discloses a two-way support frame of superimposed sheet and by its prestressing force superimposed sheet that constitutes, owing to all arranged support or truss structure on superimposed sheet is vertical and horizontal direction, so both satisfied the fore-and-aft intensity requirement of superimposed sheet, satisfied the horizontal intensity requirement of superimposed sheet again, not only be applicable to the veneer, still be applicable to the double plate.
