Problems solved by technology

[0005] The purpose of the present invention is to provide a multi-constraint reinforced concrete column wall structure, structural system and construction method thereof, to solve the technical problem that the existing double-layer steel plate composite shear wall still has the phenomenon of local buckling under reciprocating earthquakes; At the same time, it solves the technical problem that the inner-filled concrete is only restrained by the out-of-plane restraint steel plate, and the advantages of vertical bearing capacity, ductility and energy dissipation capacity are not obvious.

Embodiment 1

[0084] Embodiment one sees Figure 1-Figure 4 As shown, a multi-constraint reinforced concrete column wall structure includes a wall, the wall is an inline wall, and the inline wall is a wall steel frame tube 1 surrounded by steel plates and Two rows of connectors 2 are arranged in the wall steel frame tube along its height direction, and the two ends of the connectors 2 are connected to the front and rear sides of the wall steel frame tube and divide the interior of the wall steel frame tube into For the three connected concealed column spaces, each concealed column space is provided with a through-concealed column reinforcement cage 3 at the same height as the wall, and wall concrete 4 is integrally poured in the concealed column space.

[0085] The inner side of the node area of ​​the wall steel frame tube described in this embodiment is fixedly connected with a horizontal transverse partition 5, and each node area is provided with two transverse partitions, and the distanc...

Embodiment 2

[0087] Embodiment two see Figure 5-Figure 8 As shown, the difference from Embodiment 1 is that the transverse partition 5 is a whole plate 5.1 adapted to the size of the wall steel frame tube, and its four sides are closed and connected with the inner side of the wall steel frame tube 1, and there are holes on the plate The hole 6 that is larger than the size of the concealed column reinforcement cage and passes through it. The shape of the hole 6 in this embodiment is rectangular, and in other embodiments it can also be other polygons or circles, and the cross-sectional shape of the steel cage 3 through the concealed column is rectangular, and it can also be other polygons in other embodiments. or round.

Embodiment 3

[0088] Embodiment three see Figure 9-Figure 12 As shown, the difference from the second embodiment is that a non-penetrating concealed column reinforcement cage 7 is provided between the transverse partitions 5 in adjacent node areas, and the non-penetrating concealed column reinforcement cage 7 is connected to the upper or lower side of the transverse partition 5 Fixedly connected, the size of the non-penetrating concealed column reinforcement cage 7 is greater than the size of the hole 6 .

Abstract

The invention discloses a multiple constraint reinforced concrete column type wall structure, a structure system and a construction method of the structure system. The column type wall structure comprises a single piece wall or is formed by connecting two or more single piece walls; the column type wall structure further comprises wall body steel frame cylinders and one array or two or more arrays of connecting pieces arranged at intervals, wherein the wall body steel frame cylinders of the single piece walls are formed by enclosing steel plates, and the connecting pieces are arranged in the wall body steel frame cylinders in the height directions of the wall body steel frame cylinders; the two ends of the connecting pieces are connected to the front sides and the rear sides of the wall body steel frame cylinders to divide the interiors of the wall body steel frame cylinders into concealed column spaces which communicate with one another; each concealed column space is provided with penetrating concealed column steel reinforcement cages correspondingly; wall body concrete is integrally poured in the concealed column spaces; and horizontal transverse partition plates are fixedly connected on the inner sides of joint areas of the wall body steel frame cylinders. According to the multiple constraint reinforced concrete column type wall structure, the structure system and the construction method of the structure system, the mass is small, strength is high, the energy dissipation ability is high, most of work can be completed through a prefabrication method, the construction period is shortened, the construction quality is improved, high altitude operation is facilitated, and good seismic performance is achieved.

Description

technical field [0001] The invention relates to a multi-constraint reinforced concrete column wall structure, a structural system and a construction method thereof. Background technique [0002] With the development of building technology and the increase of structural height, the vertical load on the bottom shear wall of super high-rise buildings is increasing. In order to ensure the ductility of the shear wall, the axial compression ratio of the shear wall must be strictly controlled. At this time, the thickness of the wall must be increased, but too thick the wall will increase the self-weight of the structure, reduce the effective use area and complicate the construction. Therefore, the total height and space of the reinforced concrete shear wall structure are limited to some extent. Structural shear walls can solve this problem, but excessive steel consumption will increase the cost, and it also has some shortcomings. [0003] Therefore, the double-layer steel plate co...
