Abstract
The invention discloses a composite floor slab and a construction method thereof. The composite floor slab comprises a prefabricated base plate, a cast-in-place concrete composite layer, plate surface steel bars and plate bottom steel bars; lifting trusses are installed on the prefabricated base plate and connected with the prefabricated base plate through connecting nuts, and the lifting trusses can be disassembled after the prefabricated base plate is lifted to the specific location. The construction method for manufacturing the composite floor slab comprises the following steps that firstly, the prefabricated base plate on which the lifting trusses are installed is lifted to the specific location; secondly, supports are arranged on the bottom of the prefabricated base plate, and the lifting trusses are disassembled; thirdly, the plate surface steel bars are placed, the cast-in-place concrete composite layer is poured, after cast-in-place concrete reaches certain strength, the supports are disassembled, and the composite floor slab is formed. According to the composite floor slab and the construction method thereof, the component size is the same as a room, the assembly is not needed, no joint seam exists, the construction is convenient and fast, industrialization can be achieved, and the construction speed is greatly improved.
Description
Technical field:
Design building construction field of the present invention, specifically refers to a kind of laminated floor slab and construction method thereof.
Technical background:
Have some highrise buildings to adopt laminated floor slab at present, easy construction, do not need on-the-spot formwork, and cost is relatively low, lifting, convenient transportation.A kind of reinforced concrete laminated floor slab (application number: 201110258070.3) propose a kind of reinforced concrete laminated floor slab of patent application, comprise prefabricated panels with ribbing, transverse reinforcement and concrete folding layer, this reinforced concrete laminated floor slab have employed fixing elongated connecting rod, solves faulting of slab ends appears in prefabricated panels with ribbing situation at edge joint position.But in fact prefabricated panels with ribbing still exists piece, after concreting overlapping layers, still likely there is out-of-flatness phenomenon in floor slab bottoms, affects attractive in appearance, at the bottom of wiping tablet, need thicken rendering layer, increases operating expenses.
Summary of the invention:
For solving the problem, the invention provides a kind of laminated floor slab, comprise prefabricated panel, cast-in-situ concrete overlapping layers, reinforcement, plate face reinforcing bar, it is characterized in that: in prefabricated panel, be embedded with nut, truss hoisting is connected with prefabricated panel by coupling nut, and truss hoisting is detachable.The construction method of this laminated floor slab: (1) hoisting prefabricated base plate is to assigned address; (2) support is set under prefabricated panel, removes truss hoisting; (3) place reinforcing bar, build cast-in-situ concrete overlapping layers.Laminated floor slab prefabricated panel of the present invention adopts whole plate, and namely prefabricated panel size is identical with room axial dimension size, carries out pre-formed, be transported to job site and lift in factory.Truss hoisting comprises coupling nut, truss hoisting supporting steel pipe, truss hoisting web member, truss fastening nut composition, and each ingredient of truss hoisting all adopts the larger hard material of rigidity to make.Truss hoisting the lifting that object is to facilitate concrete prefabricated side form block is set, and truss hoisting can be dismantled, and can recycle after disassembling truss hoisting, saving resource and construction cost.The manufacturing process of the prefabricated panel with truss hoisting is as follows: build prefabricated panel, when concrete does not also harden completely, truss hoisting is arranged on prefabricated panel surface, the coupling nut of its one end is made to submerge in concrete, nut also can weld anchor bar, strengthen the adhesion stress of truss hoisting and concrete prefabricated side form interblock, after concrete hardens reach intensity completely, truss hoisting and prefabricated panel form entirety.For avoiding overflowing into concrete in coupling nut, nut can be made into semi-enclosed, dismounting truss hoisting after facilitating lifting to complete.When removing truss hoisting, can first back out truss fastening nut, pull down truss hoisting web member, then pull down truss hoisting supporting steel pipe, coupling nut can be stayed in prefabricated panel.Be configured with two-way concrete slab in prefabricated panel, ensure that the bearing capacity of floor.The construction method that this laminated floor slab adopts is simple and quick, and without the need to assembled, there will not be piece, thus there will not be faulting of slab ends phenomenon at the bottom of same room with them floor plate, prefabricated panel, can industrialization at produce in factory.The setting of truss hoisting improves speed and the quality of lifting operation, accelerates speed of application, reduces the damage to component in hoisting process, provides cost savings greatly.In work progress, by prefabricated panel lifting to assigned address, a small amount of support is set at the bottom of prefabricated panel plate, then on prefabricated panel, lays reinforcing bar, build one deck cast-in-situ concrete, reach after some strength until concrete, remove and support formation laminated floor slab.Adopt technical solution of the present invention; it is also advantageous in that the position that effectively can ensure plate face reinforcing bar; be not operated in work progress; when floor plan adopts two-way elongated installation plate face reinforcing bar; the support of some can be placed at prefabricated panel upper surface; can ensure that the position of reinforcing bar is accurate; can not be sagging or stepped down by staff in work progress, thus can not occur because plate face Minimum Concrete Protective Coating Thickness is excessive and bearing capacity of floor slab is weakened to some extent or causes the phenomenons such as floor cracking.
Describe the present invention below in conjunction with the drawings and specific embodiments, but not as limitation of the present invention.

Detailed description of the invention:
Below in conjunction with the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is described further.
The present invention as shown in figs 1-9.
With reference to figure 1-7, a kind of laminated floor slab, comprises prefabricated panel 1, cast-in-situ concrete overlapping layers 2, reinforcement 3, plate face reinforcing bar 7, is embedded with coupling nut 4 in prefabricated panel 1, truss hoisting 5 is connected with prefabricated panel 1 by coupling nut 4, and truss hoisting 5 is detachable.Truss hoisting 5 is by coupling nut 4, truss hoisting supporting steel pipe 8, and truss hoisting fastening nut 9, truss hoisting web member 10 forms.The prefabricated panel 1 having installed truss hoisting 5 is lifted, make it to be placed on Vierendeel girder 11 back, after placing, the support of some is set at the bottom of prefabricated panel plate, then truss hoisting fastening nut 9 is backed out, remove truss hoisting abdomen 10 bar and truss hoisting supporting steel pipe 8 in order, truss hoisting 5 is pulled down; Above prefabricated panel 1, place plate face reinforcing bar 7, build cast-in-situ concrete overlapping layers 3, reach after some strength until concrete, remove support 6, form laminated floor slab.This laminated floor slab, without the need to assembled, does not have splicing seams, and whole plate lifting is convenient and swift, and good integrity, substantially increases speed of application, can implement batch production, industrialization.
