Abstract

The utility model discloses a rebar joint structure of a prefabricated stacked balcony slab and a main body. The rebar joint structure comprises a prefabricated balcony slab, a prefabricated frame beam, and a pre-stress plate. The prefabricated balcony slab, the prefabricated frame beam, and the pre-stress plate are integrated in a pouring mode through a balcony cast-in-site pouring stacking layer. The pre-stress plate is integrated with the prefabricated frame beam in a pouring mode through a pre-stress plate cast-in-site layer. Rebars are distributed on a stacking face between a prefabricated balcony base plate and the balcony cast-in-site pouring stacking layer. Compared with the prior art, the rebar joint structure has the advantages of reinforcing the integrality of the connection of the prefabricated stacked balcony slab and the main body, being simple in method, being increased little in manufacture cost, bringing convenience to on-site construction, effectively improving the connection structure of the prefabricated stacked balcony slab, and improving the anti-earthquake performance of a prefabricated assembling building.

Description

The reinforcing bar drawknot structure of a kind of prefabricated superimposed balcony slab and main body
Technical field
The utility model relates to industrialization of construction industry and prefabrication and assembly construction technology, relates in particular to the reinforcing bar drawknot structure of a kind of prefabricated superimposed balcony slab and main body.
Background technology
Prefabricated superimposed balcony slab is the member that prefabricated dwelling house often adopts.The steel bar stress on balcony slab top is located at the in-situ layer of superimposed sheet, and stretches into the in-situ layer anchoring of agent structure laminated floor slab, reaches and bears the function that balcony loading connects agent structure.Prefabricated superimposed balcony slab is compared with cast-in-place balcony slab, only has top reinforcement to be connected with main body.The bottom of superimposed balcony slab is connected with body pillar no-reinforcing-bar.There is like this following point:
1, prefabricated superimposed balcony slab only has top one deck reinforcing bar to be connected with body pillar, and rigidity and the structural design analysis at its bearing place have gap.
2, the globality that balcony is connected with main body is poorer than Bars In Poured Concrete Slab.
3, when outside degree of choosing when larger, may have potential safety hazard under the vertical seismic force effect.
4, the prefabricated superimposed slab balcony had at present is by adopting the bottom muscle reserved, inserting the connectivity problem that the agent structure beam reinforcement cages solves prefabricated superimposed balcony slab and main body.But preformed plate bottom muscle unusual trouble on the making of member, transportation, installation, plate hoisted in position supervisor, be difficult for construction, and construction error is large and MU efficiency is low.
The utility model content
The problems referred to above that the utility model need to solve are for above-mentioned the deficiencies in the prior art, and a kind of good integrity is provided, and method is simple, and the cost increase is very little, are convenient to prefabricated superimposed balcony slab that site operation and anti-seismic performance are high and the reinforcing bar drawknot structure of main body.
For solving the problems of the technologies described above, the technical solution adopted in the utility model is:
The reinforcing bar drawknot structure of a kind of prefabricated superimposed balcony slab and main body, comprise that prefabricated balcony plate, prefabricated frame are set a roof beam in place, prestressed slab, prefabricated balcony plate, prefabricated frame are set a roof beam in place and prestressed slab is built and is integral by the cast-in-place overlapping layers of balcony, and prestressed slab sets a roof beam in place to build by prestressed slab in-situ layer and prefabricated frame and be integral, the joint face between prefabricated balcony base plate and the cast-in-place overlapping layers of balcony is provided with distribution reinforcement.
The colligation of setting a roof beam in place of distribution reinforcement and prefabricated frame is integral.
The length direction that the length direction of distribution reinforcement and prefabricated frame are set a roof beam in place is perpendicular.
Compared with prior art, the beneficial effects of the utility model are: strengthened the globality that prefabricated superimposed balcony slab is connected with main body, method is simple, the cost increase is very little, be convenient to site operation, effectively improved the connection structure of prefabricated superimposed balcony slab, improve the anti-seismic performance of prefabrication and assembly construction building.
The accompanying drawing explanation
Fig. 1 is the structural representation of the reinforcing bar drawknot structure of prefabricated superimposed balcony slab and main body;
Wherein, 1, prefabricated balcony plate; 2, the cast-in-place overlapping layers of balcony; 3, prefabricated frame is set a roof beam in place; 4, prestressed slab; 5, prestressed slab in-situ layer; 6, steel bar stress; 7, distribution reinforcement.
The specific embodiment
Describe optimal technical scheme of the present utility model in detail below in conjunction with accompanying drawing.
As shown in Figure 1, the reinforcing bar drawknot structure of a kind of prefabricated superimposed balcony slab and main body, comprise that prefabricated balcony plate 1, prefabricated frame set a roof beam in place 3, prestressed slab 4, prefabricated balcony plate 1, prefabricated frame set a roof beam in place 3 and prestressed slab 4 build and be integral by the cast-in-place overlapping layers 2 of balcony, and prestressed slab 4 is set a roof beam in place by prestressed slab in-situ layer 5 and prefabricated frame and 3 built and be integral, the joint face between prefabricated balcony base plate 1 and the cast-in-place overlapping layers of balcony is provided with distribution reinforcement 7.
3 colligations of setting a roof beam in place of distribution reinforcement 7 and prefabricated frame are integral.
Set a roof beam in place 3 length direction of the length direction of distribution reinforcement 7 and prefabricated frame is perpendicular.
