Description
Technical field
The present invention relates to a kind of structure of building engineering field more particularly to prefabricated components constructions.
Background technology
Prefabricated assembled mode of construction brings the production efficiency significantly improved, and at present, China is dedicated to building industrialization
Research and development.Building industrialization can improve construction efficiency, promote architecture quality, low-carbon energy-saving, meet sustainable development,
It is the effective way that building is transformed the mode of development.
At present, in China's prefabricated concrete structure common floor form be truss bars laminated floor slab, laminated floor slab
With good integrity, lower surface is smooth, the advantages that can saving construction formwork.However, precast concrete volume is in building in superimposed sheet
Proportion still needs to binding upper reinforcement and casting concrete, with precast beam, column at the construction field (site) less than 50% in plate total volume
Components is waited to compare, industrialization degree is not high；The use of girder rib improves component cost in superimposed sheet；Electromechanical pipeline still needs in plate
Scene is laid with, and electromechanical facility fails to realize industrialized production.
Invention content
The technical problem to be solved in the present invention is to provide a kind of prefabricated board connecting structure, this kind of prefabricated board industrialization degrees
Height improves prefabricated rate；Arrangement girder rib, low cost are not required in plate；Rigidity is big, disclosure satisfy that demoulding, lifting requirements；Join domain
Standardization, can realize the molding reinforced mesh of laying standard, scene support less, concreting and pipelay work
Few, construction is convenient.
The basic technical scheme one that the present invention takes is connect for superimposed sheet with composite beam；Superimposed sheet is by plate pre-erection and plate
Cast-in-place part composition；Composite beam is made of beam prefabricated part and the cast-in-place part of beam；The cast-in-place part of plate and the cast-in-place part of beam are located at folded
Close the join domain of beam and superimposed sheet；Stepped, the plate pre-erection that the shape of plate pre-erection is sunk for intermediate protrusion, surrounding
Top bars stretch out the intermediate raised zones of plate pre-erection, lower floor's reinforcing bar of plate pre-erection do not stretch out plate pre-erection
Outside surrounding sunken regions；The additional lower floor's reinforcing bar of lower floor's setting of the cast-in-place part of plate, additional lower floor's reinforcing bar are taken indirectly with lower floor reinforcing bar
It connects；The upper strata of the cast-in-place part of plate is laid with reinforced mesh, and reinforced mesh is overlapped with top bars.
The basic technical scheme two that the present invention takes is connect for superimposed sheet with wall；Superimposed sheet is cast-in-place by plate pre-erection and plate
Part forms；Wall is made of wall pre-erection and the cast-in-place part of wall top；The cast-in-place part of plate and the cast-in-place part of wall top are located at superimposed sheet
With the join domain of wall；Stepped, the upper strata steel of plate pre-erection that the shape of plate pre-erection is sunk for intermediate protrusion, surrounding
Muscle stretches out the intermediate raised zones of plate pre-erection, and lower floor's reinforcing bar of plate pre-erection does not stretch out the surrounding sinking of plate pre-erection
Outside region；The additional lower floor's reinforcing bar of lower floor's setting of the cast-in-place part of plate, additional lower floor's reinforcing bar overlap indirectly with lower floor reinforcing bar；Plate is cast-in-place
Partial upper strata is laid with reinforced mesh, and reinforced mesh is overlapped with top bars.
The horizontal connection between superimposed sheet and superimposed sheet of basic technical scheme three that the present invention uses；Superimposed sheet is prefabricated by plate
Part and the cast-in-place part composition of plate；Join domain of the cast-in-place part of plate between superimposed sheet；During the shape of plate pre-erection is
Between protrusion, surrounding sink stepped, the top bars of plate pre-erection stretch out the intermediate raised zones of plate pre-erection, and plate is pre-
Lower floor's reinforcing bar of part processed is not stretched out outside the surrounding sunken regions of plate pre-erection；The additional lower floor of lower floor's setting of the cast-in-place part of plate
Reinforcing bar, additional lower floor's reinforcing bar overlap indirectly with lower floor reinforcing bar；The upper strata of the cast-in-place part of plate is laid with reinforced mesh, reinforced mesh with it is upper
Layer bar splicing.
By the overlap joint of reinforcing bar between plate pre-erection and the cast-in-place part of plate, solves the problems, such as stress.Plate pre-erection
The step size dimension that surrounding is sunk can determine that the lap of splice can be according to existing according to lapped length of steel bar and releasing process requirement
Some Code for design of concrete structures determine.Pipeline plate pre-erection or can be laid in the cast-in-place part of plate by nuzzling in advance, existing
Field only need to can be laid with reinforced mesh, and then realize rapid construction in the join domain of superimposed sheet and other components.
Beneficial effects of the present invention are：
1. prefabricated degree is high, precast concrete volume can be in floor proportion up to 60%.
2. prefabricated rate is promoted, monomer pre-emulsion rate 7% or so can be improved.
3. since the surrounding of the plate pre-erection in superimposed sheet does not go out muscle, template construct is simple, can realize full-automation
It produces and reduces formwork cost.
4. since the surrounding of the plate pre-erection in superimposed sheet does not go out muscle, beam stirrup and plate can be avoided in assembling members
The collision of reinforcing bar improves in-site installation efficiency.
5. site operation efficiency can be improved in the molding reinforced mesh of join domain laying standard.
