Problems solved by technology

Nowadays, the vertical and horizontal walls of prefabricated shear walls mainly adopt the connection technology of combining horizontal reinforcement rings and vertical insertion bars. Because this kind of connection is not enough for the concrete constraints at the joints, during earthquakes, the joints will be under the repeated action of bending moment and shear force. The concrete is crushed and falls off, and the steel bars gradually fail, eventually leading to the destruction of the entire structure, and the structure in the joint area is complex, the construction is difficult, and it is difficult to ensure the construction quality

Embodiment Construction

[0011] refer to figure 1 , figure 2 , there is a square steel pipe 4 in the core area of ​​the node. There are three panels on each side of the square steel tube, and a column of panels 2 is arranged on each side. The vertical spacing of the panels is even, and the panels on two adjacent vertical surfaces are staggered to avoid mutual influence. , this node structure is suitable for T-shaped intersecting wall panels.

[0012] refer to figure 1 , image 3 , there is a square steel pipe 4 in the core area of ​​the node. There are two columns of panels 2 on both sides of the square steel tube. The vertical spacing of the panels is uniform. The panels on two adjacent vertical surfaces are staggered to avoid mutual Influence, this node structure is suitable for L-shaped intersecting wall panels.

[0013] During construction, the vertical and horizontal wall panels 1 and 3 are first hoisted to the designated positions. After the vertical and horizontal wall panels are positione...

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 [0001] The invention relates to the technical field of civil engineering, in particular to a structural system of an assembled section steel confined concrete shear wall. Background technique [0002] The prefabricated assembly shear wall structure is a relatively common form in the assembly structure. The structure is composed of basic components such as prefabricated shear wall panels. The components are pre-fabricated in the factory and then installed on the construction site. A series of advantages such as fast speed and low construction cost have become a strong support for the modernization of the construction industry. [0003] The performance of connecting nodes is an important factor affecting the integrity of prefabricated structures, and a large number of earthquake damage shows that the damage of prefabricated structures is mostly concentrated at the nodes. Nowadays, the vertical and horizontal walls of prefabricated shear walls mainly adopt the ...
