Abstract
The invention discloses a truss type dense-rib hollow superposed floor, and belongs to the dwelling house integrated technical field; the superposed floor comprises a plurality of prefabricated floor slabs, a top plate, foaming concrete blocks, rectangular steel bar trusses, normal beam ribs, a bottom plate, and seams casted on side faces of the prefabricated floor slabs; the bottom plate top surface is provided with a plurality of rectangular steel bar trusses and normal beam ribs; the rectangular steel bar trusses are vertically arranged at equal intervals; the normal beam ribs are transversely arranged at equal intervals; the seams are arranged on adjacent side faces of the prefabricated floor slabs, and used for bidirectionally connecting the prefabricated floor slabs. The truss type dense-rib hollow superposed floor is suitable for wide span industry and civil floors, is bidirectionally force bearing, and reasonable in force bearing; the rectangular steel bar trusses on the prefabricated slabs can enhance the rigidity, thus increasing prefabricated slab anti-deformation ability in storage, transport and hoist processes; the truss type dense-rib hollow superposed floor can serve as bed die so as to greatly increase bearing ability in field casting of top plate and ribs.
Description
Technical field:
The invention belongs to house all-in-one technical field, relate to building prefabricated components, be specifically related to a kind of truss-like hollow superposed floor of close rib.
Background technology:
As the developing direction of Future Residential Housing, prefabricated concrete structure is the major trend carrying out building industrialization energetically.Floor framing is as structural bearing component, its Main Function is that the vertical load of flooring is passed to beam column, therefore there is in structure entirety important connection, stress effect, and there is bigger construction volume, the reasonable assemblingization therefore realizing superstructure has important meaning to structure stress and construction.
There is the problem that some are universal in the most common superposed floor: first is single load bearing superstructure, it is impossible to realize bigger two-way span.Second, Prefabricated stacking floor thickness is thin, rigidity is little, in way, breakage, phenomenon of rupture easily occurs in transport, lifting, some superposed floors for avoiding this problem, pre-buried triangular reinforced bar truss in precast floor slab, but it is as girt strip reinforcing steel bar bear poor performance.3rd, the overlapping layers that precast floor slab pours mostly is solid, from great, strongly limit span.
To this end, the present invention proposes a kind of rectangle truss-like hollow superposed floor of close rib, there is the advantages such as bidirectional stress, precast floor slab rigidity is big, rectangle steel bar girder accepts rationally as girt strip reinforcing bar, it is little to conduct oneself with dignity, rigidity is big, solve problem above in the lump.
Summary of the invention:
It is an object of the invention to provide a kind of truss-like hollow superposed floor of close rib, to solve the problems such as existing superposed floor single load bearing, span is little, rigidity is little.Additionally, the rectangle steel bar girder being provided with in superposed floor of the present invention increases the rigidity of precast floor slab, it is to avoid precast floor slab is in transport and the damage of hoisting process.
