Assembling shaped steel confined concrete shear wall structure
The present invention relates to technical field of civil engineering, be specially assembling shaped steel confined concrete shear wall structure system.
Prefabricated assembled shear wall structure is form comparatively common in fabricated construction, this structure is made up of basic building blocks such as precast shear wall wallboards, component makes in advance in the factory, arrive job site again to install, there is the series of advantages such as construction quality is good, speed of application is fast, construction cost is low, become and realize the modern powerful support of building industry.
The performance of connected node is the key factor affecting fabricated construction globality, and a large amount of earthquake shows that the destruction of fabricated construction focuses mostly in Nodes.Fabricated shear wall longitudinal cross wall mainly adopts the link technique that horizontal reinforcement ring combines with vertical joint bar now, because this kind connects to the constraint of Nodes concrete not, when earthquake, node crushing of concrete under the repeated action of bending and shearing comes off, reinforcing bar lost efficacy gradually, finally caused the destruction of total, and complex structure in node region, difficulty of construction is comparatively large, not easily ensures construction quality.
Summary of the invention
The object of this invention is to provide a kind of assembling shaped steel confined concrete shear wall structure system, fabricated shear wall longitudinal cross wall two ends can being furnished with shaped steel reliably connects, improve the globality of fabricated shear wall structure and the anti-seismic performance of connected node, ensure construction quality.
For achieving the above object, the invention provides a kind of assembling shaped steel confined concrete shear wall structure, comprise wallboard in length and breadth, it is characterized in that: fabricated shear wall in length and breadth wall panel ends is furnished with H profile steel and the edge of a wing of H profile steel side is exposed, joint cores is provided with a steel pipe, the H profile steel edge of a wing of exposing vertically connects a batten plate every a segment distance, the batten plate other end is fixed on steel pipe, thus H profile steel and square steel pipe are connected by batten plate and form node area skeleton, node area skeleton place has built concrete and has been connected to form overall shear wall with wallboard in length and breadth.
The connection batten plate of wallboard staggers mutually in length and breadth.
The steel pipe that joint cores is arranged is square steel pipe or round steel pipe.
The present invention is by batten plate will wallboard and core fastener for connection be integrally in length and breadth, when being subject to seismic load, type steel skeleton same level circumferential reinforcement is compared, because area node region concrete being produced to constraint increases, therefore, it is possible to provide stronger radial reaction force, more effectively constrain carrying out of concrete distortion and crack, given full play to concrete bearing capacity ability, the anti-seismic performance of node region is improved, and structural system has good overall performance.This structural system construction technology is simple, is convenient to install template and reduces the wet trade amount of job site.

Detailed description of the invention
With reference to Fig. 1, Fig. 2, Fig. 3, the specific embodiment of the invention comprises wallboard 1,3 in length and breadth, wall panel ends is furnished with H profile steel 5 and the edge of a wing of H profile steel side is exposed in length and breadth, joint cores is provided with a square steel pipe 4, the H profile steel edge of a wing of exposing vertically connects a batten plate 2 every a segment distance, the batten plate other end is fixed on square steel pipe, thus H profile steel 5 and square steel pipe 4 are connected by batten plate 2 and form node area skeleton, node area skeleton place has built concrete 6 and has been connected to form overall shear wall with wallboard in length and breadth, and wallboard 1,3 is prefabricated panel in length and breadth.
During construction, first wallboard 1,3 to assigned address is in length and breadth lifted, in length and breadth wallboard location ready after, place square steel pipe 4 in joint cores, batten plate 2 one end is welded on square steel pipe 4, and the other end is welded in longitudinal cross wall panel edges H profile steel 5, node vertically welds one block of batten plate 2 every a segment distance, the connection batten plate of cross wall and vertical wall staggers mutually, avoids influencing each other, and last formwork is at whole node region concreting 6.
