Abstract
The invention discloses a prefabricated overlapped hollow floor and a fabricating method thereof, wherein the prefabricated overlapped hollow floor is provided with a cast-in-place layer and a prefabricated layer; truss rebars or hidden beam rebars are arranged on the prefabricated layer, and hollow boxes or light blocks are fixed among the truss rebars or the hidden beam rebars; and on the construction site, by placing the rebars and then casting the concrete on site on the prefabricated layer, the truss rebars and the hollow boxes or the light blocks are embedded in the cast-in-place layer, and are jointly fixed with the prefabricated layer to form an integral floor. The prefabricated overlapped hollow floor has light self weight, is internally provided with the truss rebars, has excellent structural performance as the cast-in-place layer and the prefabricated layer are satisfactorily jointed, and needs no formwork, simplifies the construction, and improves the economical benefits as compared with the conventional cast-in-place hollow floor.
Description
Technical field
The present invention relates to construction engineering technical field, be specifically related to a kind of prefabricated sandwich hollow slab and manufacturing approach thereof.
Background technology
The cast-in-situ hollow floor plate construction of prior art is complicated, because voided layer is different with cast-in-situ concrete density, the hollow body piece floats in concrete easily, so floor boring layer is difficult for accurately location, can only before cast-in-place, hollow box be fixed, and does cast-in-place again.And cast-in-situ floor needs the template support, the construction complicacy.
Summary of the invention
Technical problem to be solved by this invention is: solve the problem that above-mentioned prior art exists; And providing a kind of prefabricated sandwich hollow slab and manufacturing approach thereof, precast plate hollow core box or light plastid piece accurately to locate, floor slab construction need not template; Simplify construction; Preformed layer and in-situ layer are combined, and reduce deadweight, improve bending resistance anti-crawl agentdefiection ability.
The technical scheme that the present invention adopts is:
A kind of prefabricated sandwich hollow slab has in-situ layer and preformed layer, arranges on the preformed layer to be fixed with truss bars or dark beam steel, fixation hollow box or light plastid piece between truss bars or dark beam steel.Reproduce pouring concrete truss bars and hollow box or light plastid piece are imbedded in the in-situ layer through on preformed layer, placing reinforcing bar at the construction field (site), and combines to fix the whole floor of formation with preformed layer.
A kind of manufacturing approach of prefabricated sandwich hollow slab: when the moulding of preformed layer ot-yet-hardened, fixation hollow box or light plastid piece between truss bars or dark beam steel.Maintenance moulding then.At the construction field (site), through on preformed layer, placing reinforcing bar cast-in-situ concrete again, preformed layer and in-situ layer are combined into superimposed cast-in-situ hollow floor plate.
Operating principle:
Utilize the leg-of-mutton stability of truss bars, the girder-embedded reinforcing bar of precast plate is combined closely itself and in-situ layer, solves preformed layer and cast-in-place surface layer shearing resistance problem; The built-in big hollow body piece of superimposed sheet is guaranteeing on the constitutionally stable prerequisite, alleviates the floor deadweight, reduces gravity load, increases floor anti-crawl agentdefiection degree ability.Utilize the advantage of this two aspect, be made into prefabricated sandwich hollow slab.
Advantageous effect:
The precast hollow laminated floor slab from heavy and light, is arranged truss bars in the floor, preformed layer and in-situ layer associativity are good.Compared to traditional cast-in-situ hollow floor plate, need not template, simplify construction, increase economic efficiency.
This prefabricated sandwich hollow slab has good structural performance, and advantage is outstanding, and there is demand in market, and the excellent popularization prospect is arranged.
Description of drawings
Fig. 1 is a schematic cross-section of the present invention;
Fig. 2 is a structural plan of the present invention sketch map.
Among the figure, 1-preformed layer, 2-in-situ layer, 3-truss bars, 4-hollow box or light plastid piece.
The specific embodiment
Referring to Fig. 1; Prefabricated sandwich hollow slab of the present invention; Have in-situ layer 2 and preformed layer 1, arrange on the preformed layer 1 to be fixed with truss bars 3,3 fixation hollow boxes of truss bars or light plastid piece 4; In-situ layer 2 is truss bars 3 and hollow box or light plastid piece 4 cast-in-place imbedding, and combines to fix with preformed layer 1.
A kind of manufacturing approach of prefabricated sandwich hollow slab: when the moulding of preformed layer ot-yet-hardened, fixation hollow box or light plastid piece between truss bars or dark beam steel.Maintenance moulding then.At the construction field (site), through on preformed layer, placing reinforcing bar cast-in-situ concrete again, preformed layer and in-situ layer are combined into superimposed cast-in-situ hollow floor plate.
Claims (2)
1. a prefabricated sandwich hollow slab is characterized in that: have in-situ layer and preformed layer, be furnished with truss bars or dark beam steel on the preformed layer, fixation hollow box or light plastid piece between truss bars or dark beam steel; Reproduce pouring concrete truss bars and hollow box or light plastid piece are imbedded in the in-situ layer through on preformed layer, placing reinforcing bar at the construction field (site), and combines to fix the whole floor of formation with preformed layer.
2. the manufacturing approach of a prefabricated sandwich hollow slab is characterized in that: when the moulding of preformed layer ot-yet-hardened, and fixation hollow box or light plastid piece between truss bars or dark beam steel, maintenance moulding then; At the construction field (site), through on preformed layer, placing reinforcing bar cast-in-situ concrete again, preformed layer and in-situ layer are combined into superimposed cast-in-situ hollow floor plate.
