Abstract
The invention provides a connecting joint of an assembled profile steel confined concrete shear wall structure. The connecting joint is characterized in that a steel pipe is arranged in a joint core area; batten plates are vertically uniformly arranged at intervals of every 90 degrees around the steels in the same level. According to the connecting joint, the batten plates are uniformly connected to four sides of the steel pipe by a staggering manner; compared with the horizontal annular steel bars under the earthquake load, a profile steel frame has the advantages that the confirmed area of the concrete in the joint area is increased, so that high radial reacting force can be supplied, the deformation of concrete and the expansion of cracks can be effectively limited, the bearing capacity and deformation capacity of the concrete can be brought into full play, and the earthquake resistance of the joint area can be improved; the construction process is simple; the construction quality is improved; a die plate is conveniently erected, and the wet workload at the construction site can be decreased.
Description
Technical field
The present invention relates to technical field of civil engineering, be specially assembling shaped steel confined concrete shear wall structure system.
Background technology
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 link node 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 link node, it is characterized in that: joint cores is provided with a steel pipe, steel pipe surrounding has at least both sides on the direction of two perpendicular respectively to arrange a row batten plate, and the batten plate of both direction staggers mutually.
The steel pipe that joint cores is arranged is square steel pipe.
Link node of the present invention evenly mutually to be staggered connection batten plate by the circumferentially-spaced at steel pipe, 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, give full play to concrete bearing capacity ability, the anti-seismic performance of node region is improved, construction technology is simple, improve construction quality, be convenient to install template and reduce the wet trade amount of job site.

Fig. 2 is the structural plan figure using the longitudinal cross wall T-shaped of link node of the present invention to intersect;
Fig. 3 is the structural plan figure using the longitudinal cross wall L shape of link node of the present invention to intersect.
Detailed description of the invention
With reference to Fig. 1, Fig. 2, joint cores is provided with a square steel pipe 4, square steel pipe has both sides, three faces respectively arrange a row batten plate 2, the vertical interval of batten plate is even, batten plate on two adjacent vertical planes staggers mutually, avoids influencing each other, and this kind of node structure is applicable to the crossing wallboard of T-shaped.
With reference to Fig. 1, Fig. 3, joint cores is provided with a square steel pipe 4, square steel pipe has both sides, two faces respectively arrange a row batten plate 2, the vertical interval of batten plate is even, batten plate on two adjacent vertical planes staggers mutually, avoids influencing each other, and this kind of node structure is applicable to the crossing wallboard of L shape.
During construction, first wallboard 1,3 to assigned address is in length and breadth lifted, in length and breadth wallboard location ready after, square steel pipe 4 is placed in joint cores, batten plate 2 one end is welded on square steel pipe 4, and the other end is welded on the edge of a wing that longitudinal cross wall panel edges H profile steel 5 exposes, thus H profile steel 5 and square steel pipe 4 are connected by batten plate 2 and form node area skeleton, last formwork is connected to form overall shear wall at whole node region concreting 6 and wallboard in length and breadth, and wallboard 1,3 is prefabricated panel in length and breadth.
