Description
Technical field
This utility model relates to a kind of building floor, particularly a kind of cast-in-place and precast reinforced lamination floor.
Background technology
Cast-in-place concrete floor dead load is big, concrete amount is many, be easily generated contraction fissure, and form work engineering is complicated, inconvenience installed by pipeline, applicable span is little.And although common steel bar concrete dense rib floor is lightweight, concrete amount is few, bearing capacity is high but form work engineering is complicated, sound insulation, heat insulation, fire-resistant, antidetonation, energy-efficient performance are poor, affect architecture quality and use function, and, this common steel bar concrete dense rib floor is primarily adapted for use in large spatial structure, slab thickness is big, is not as practical for ordinary residence.
Along with building increasingly trends towards modularity, scale; the use of lamination floor also increasingly receives an acclaim; existing lamination floor is built by binding reinforcing bars by precast floor slab and cast-in-situ floor and is formed; its overall shock resistance is poor; adhesive strength is low; and the template number that needs in casting process is more, labor intensity is high, and working performance is low.
Summary of the invention
This utility model provides a kind of cast-in-place and precast reinforced lamination floor for solving the technical problem of existence in known technology, and this floor construction intensity is high, it is simple to construction.
This utility model is adopted the technical scheme that by the technical problem solving to exist in known technology: a kind of cast-in-place and precast reinforced lamination floor, including precast floor slab, internal vertical at described precast floor slab is equidistantly provided with many pretightning force reinforcing bars in its length direction, is respectively formed with " 7 " shape hook being positioned at outside described precast floor slab two ends at the two ends of described pretightning force reinforcing bar；Connecting a top bars every described on two described hooks of pretightning force reinforcing bar, described top bars is positioned at the top of described precast floor slab；The upper surface of described precast floor slab is equidistantly provided with some fins along its length, described fin is equidistantly provided with and perpendicular multiple wears muscle hole, lower floor's reinforcing bar it is coated with in muscle hole described wearing, described lower floor reinforcing bar is between described top bars and described pretightning force reinforcing bar, and many described lower floor reinforcing bars are positioned at the underface of many described top barses correspondingly；Two adjacent described top barses adopt multiple rectangle stirrups to tie up fixing with the two described lower floor reinforcing bars being positioned at immediately below it；Being formed above cast-in-place concrete layer at described precast floor slab, described cast-in-place concrete layer covers on described precast floor slab and described top bars.
Described muscle hole of wearing is positioned at the surface of corresponding described pretightning force reinforcing bar.
The shape of cross section of described fin is any one in rectangle, hemispherical, trapezoidal or inverted trapezoidal.
This utility model has the advantage that and has the benefit effect that the pretightning force reinforcing bar in precast floor slab is connected with the top bars being positioned at cast-in-place concrete layer, what be positioned at that lower floor's reinforcing bar of cast-in-place concrete is arranged in precast floor slab wears muscle hole, top bars is connected by rectangle stirrup with lower floor reinforcing bar so that in precast floor slab, reinforcing bar is connected with reinforcing bar stacking in cast-in-place concrete；Being layered in together with top bars is cast in precast floor slab by cast-in-place concrete layer on precast floor slab with lower floor reinforcing bar, overall construction intensity is high.And this utility model easy construction, required template number is few, it is possible to reduce labor intensity, improves working performance, reduces construction cost.
