Abstract
Disclosed is an assembly type dense column hollow shear wall structure. Reserved hollow holes and back joint bar reserved holes are formed in a wall, and hollow dense columns of the wall are formed by the back joint bar reserved holes. Stirrups are arranged in the back joint bar reserved holes, longitudinal bars are evenly arranged along the inner sides of the stirrups, and the upper ends of the longitudinal bars stretch out of the top of the wall to form lap-joint segments. The self weight of the precast concrete unit wall is effectively reduced, the structural rigidity of the wall is lowered, the action of earthquakes is reduced, and the heat preservation and insulation effects are improved. The stirrups and the longitudinal bars are arranged in the back joint bar reserved holes, after fine aggregate concrete pouring work of the back joint bar reserved holes of the wall is completed, even and continuous three-direction stress constraining force can be applied to the concrete in the wall through the stirrups in the lateral direction, transverse deformation of the concrete can be effectively constrained, bending of the longitudinal bars can be suppressed, the compressive strain resisting capacity of the concrete at the two ends of the wall is remarkably improved, and therefore the bearing force of the wall is increased, and the overall anti-seismic property of the wall structure is improved.
Description
Technical field
The invention belongs to architecture production technical field of construction, particularly relate to the close post hollow shear wall structure of a kind of assembling.
Background technology
At present, the basic ideas of fabricated shear wall structure are that the component of building structure is divided into some unit, then in prefabricated place, moulding by casting is carried out to each unit, again by each shipped after shaping to job site, and by engineering machinery hoisted in position, finally utilize wet connected mode to form the building with fabricated shear wall structure.Because fabricated shear wall structure has good globality, and rigidity is large, bearing capacity is high, is therefore used widely in assembling highrise building.
But, for domestic assembly concrete shear wall structure, it is not perfect that its existing component splits system, precast unit deadweight after fractionation is larger, and the connection of precast unit mainly contains three kinds of modes, comprise sleeve connection mode, constraint slurry anchor overlap joint connected mode and welding connecting mode, and sleeve connection mode all needs to be connected by injecting high strength grout with constraint slurry anchor overlap joint connected mode, therefore be subject to artificial and such environmental effects is larger, cause grouting quality wayward, and after cementing operations completes, also do not have a kind of non-damage detection method can meet the inspection of quality of connection, and the integrality of junction can be destroyed by damage testing method, welding connecting mode is only applicable to multilayer fabricated shear wall structure, so this connected mode uses restriction comparatively large, and welding quality can be subject to human factor impact equally, and field operation amount is large, less economical.
Summary of the invention
For prior art Problems existing, the invention provides the close post hollow shear wall structure of a kind of assembling, the deadweight of precast unit can be reduced, avoid too much artificial disturbance, improve connection reliability and quality of connection.
To achieve these goals, the present invention adopts following technical scheme: the close post hollow shear wall structure of a kind of assembling, comprise body of wall, in described body of wall, be provided with some horizontal bars and vertically construct muscle, be characterized in: in described body of wall, be also provided with reserved hollow hole and rear joint bar reserving hole, be made up of the hollow close post of body of wall some rear joint bar reserving holes; Be provided with stirrup in joint bar reserving hole in the rear, and be evenly arranged vertical muscle inside stirrup, and body of wall top formation overlap joint linkage section is stretched out in vertical muscle upper end.
Described stirrup is arranged in the rear joint bar reserving hole of body of wall by pre-buried mode, or stirrup and vertical muscle are tied to and are integrally formed reinforcing cage and are placed in rear joint bar reserving hole.
Described body of wall sidepiece is provided with edge member, joint bar reserving hole after being also provided with in edge member, in rear joint bar reserving hole, is provided with stirrup, and has been evenly arranged vertical muscle inside stirrup, and body of wall top formation overlap joint linkage section is stretched out in vertical muscle upper end.
Described stirrup is arranged in the rear joint bar reserving hole of edge member by pre-buried mode, or stirrup and vertical muscle are tied to and are integrally formed reinforcing cage and are placed in rear joint bar reserving hole.
The material of described stirrup is metal or FRP fibre reinforced composites.
Described stirrup adopts continuous helical stirrup or rectangle hoop.
The inner surface of described rear joint bar reserving hole is matsurface or has shearing resistance groove.
Described rear joint bar reserving hole can adopt continuous penetration type or discontinuous penetration type.
The cross sectional shape of described reserved hollow hole and rear joint bar reserving hole can be circle, rectangle or ellipse.
The cross sectional shape of described body of wall can be yi word pattern, L-type, T-shaped or U-shaped.
Beneficial effect of the present invention:
The present invention, by increasing reserved hollow hole and rear joint bar reserving hole in precast unit body of wall, effectively alleviates the deadweight of precast unit body of wall, can also reduce wall body structure rigidity, reduces geological process, improves heat insulating effect; By arranging stirrup and vertical muscle in rear joint bar reserving hole of the present invention, when after the pea gravel concreten pouring practice completing joint bar reserving hole after body of wall, the concrete in it can be given in the three dimension stress restraint forces of side direction applying uniformly continous by stirrup, can the concrete lateral deformation of operative constraint, and suppress the flexing of vertical muscle, significantly improve the concrete compression set ability in body of wall two ends, thus increase the bearing capacity of body of wall, improve the overall anti-seismic performance of wall body structure.
