Abstract
The utility model discloses a prefabricated and overlapped hollow floor slab. The prefabricated and overlapped hollow floor slab is provided with a cast-in-place layer and a prefabricating layer, wherein the prefabricating layer is distributed with truss reinforcing steel bars or hidden beam reinforcing steel bars, and hollow boxes or light blocks are fixedly arranged between the truss reinforcing steel bars or the hidden beam reinforcing steel bars. On the construction field, the prefabricating layer is placed with reinforcing steel bars, then concrete is cast in place, and thus the truss reinforcing steel bars and the hollow boxes or the light blocks are embedded in the cast-in-place layer, and an integrated floor slab is formed by combining the cast-in-place layer and the prefabricating layer. The prefabricated and overlapped hollow floor slab disclosed by the utility model has the advantages that the self weight is light, the truss reinforcing steel bars are distributed in the floor slab, the combination between the prefabricating layer and the cast-in-place layer is good, and the structure performance is excellent; and compared with the traditional cast-in-place hollow floor slab, the prefabricated and overlapped hollow floor slab is free from a template, the construction is simplified, and the economic benefit is increased.
Description
Technical field
The utility model relates to construction engineering technical field, is specifically related to a kind of prefabricated sandwich hollow slab.
Background technology
The construction of the cast-in-situ hollow floor plate of prior art is complicated, because voided layer is different from cast-in-situ concrete density, hollow body piece easy floating in concrete so floor boring layer is difficult for accurately locating, can only frontly be fixed hollow box cast-in-place, does cast-in-place again.And cast-in-situ floor needs shuttering supporting, the construction complexity.
Summary of the invention
Technical problem to be solved in the utility model is: solve the problem that above-mentioned prior art exists, and provide a kind of prefabricated sandwich hollow slab, precast plate hollow core box or light plastid piece are accurately located, 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 solution adopted in the utility model 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 by place reinforcing bar at preformed layer at the construction field (site), and be combined with preformed layer and to fix the whole floor of formation.
A kind of manufacture method 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.Then maintenance moulding.At the construction field (site), by placing again cast-in-situ concrete of reinforcing bar at preformed layer, 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 large hollow body piece of superimposed sheet is guaranteeing on the constitutionally stable prerequisite, alleviates the floor deadweight, reduces gravity load, increases floor capable of resisting deflection 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, advantages, and there is demand in market, and good promotion prospect is arranged.
Description of drawings
Fig. 1 is the utility model schematic cross-section;
Fig. 2 is the utility model structural plan schematic diagram.
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 utility model, have in-situ layer 2 and preformed layer 1, arrange on the preformed layer 1 and 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 with preformed layer 1 in conjunction with fixing.
A kind of manufacture method 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.Then maintenance moulding.At the construction field (site), by placing again cast-in-situ concrete of reinforcing bar at preformed layer, preformed layer and in-situ layer are combined into superimposed cast-in-situ hollow floor plate.
Claims (1)
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 by place reinforcing bar at preformed layer at the construction field (site), and be combined with preformed layer and to fix the whole floor of formation.
