Embodiment 1

[0035] This embodiment consists of a double-layer steel plate wall 1, a main frame structure 2, a ductile energy-dissipating connector 3, a hinge support 4 at the bottom of the wall, and a flexible filling material 6. During construction, first pour the hinge support 4 at the bottom of the wall, such as Figure 4 As shown, the hinge support 4 at the bottom of the wall is made of reinforced concrete into a groove shape, the width is the same as the thickness of the double-layer steel plate wall 1, the length of the bottom of the groove is the same as the length of the bottom end of the double-layer steel plate wall 1, and the edge of the groove is at a certain angle with the horizontal plane. The steel plate in the tank is used as the contact surface, and the steel plate and the reinforced concrete part are anchored by bolts, and the concrete is vibrated and compacted after pouring.

[0036] The double-layer steel plate wall 1 is a prefabricated component, such as figure 2 As...

Embodiment 2

[0040] Figure 5 It is the elevation schematic diagram of the double-layer steel plate wall part in this embodiment. For the prefabricated double-layer steel plate swing wall assembly with ductile energy-dissipating connectors set at the position where the distance between the frame columns 202 is relatively large, it can be as follows Figure 5 and Figure 6 As shown, the outrigger connection 5 is set, and the strengthening member is set in the wall.

[0041] One end of the outrigger connection 5 is welded to the double-layer steel plate wall 1, and the other end is welded to 303 and connected to the ductile energy-dissipating connector 3; the flange plate of the outrigger connection 5 is gradually widened near the double-layer swinging wall 1, And extend into the double-layer steel plate wall 1 inside.

[0042] The edge-constrained square steel pipe of the double-layer steel plate wall 1 is provided with a transverse diaphragm 108 with a round hole at the position of the ...

Abstract

The invention relates to a fabricated double-layer steel plate swinging wall with ductility energy consumption connecting pieces, which is used for energy consumption and shock absorption of a frame structural building in an earthquake. The swinging wall disclosed by the invention structurally is formed by a double-layer steel plate wall, a main body frame structure, the ductility energy consumption connecting pieces, a wall bottom hinged support, a flexible filling material and a lateral positioning bolt. The double-layer steel plate wall is connected with the main body frame structure by adopting the fabricated ductility energy consumption connecting pieces, so that energy consumption capacity of the structure under the earthquake is reinforced; the wall bottom hinged support is arranged at the bottom of the double-layer steel plate wall, so that swing performance is sufficiently guaranteed; a strip bolt hole is formed at the position on a wall body, which is in parallel to a frame beam, and the wall body is connected with the frame beam by the lateral positioning bolt, so that a horizontal displacement of the top of the double-layer steel plate wall and a horizontal displacement of the frame beam are guaranteed to be the same; sections of the double-layer steel plate wall are connected by bolts; holes need to be opened at corresponding positions on a floor, where the double-layer steel plate wall is inserted into the floor, and the flexible material is arranged between the floor and the double-layer steel plate wall, so that direct collision between the floor and the double-layer steel plate wall is prevented.

Description

(1) Technical field [0001] The invention belongs to the technical field of civil engineering structures, and relates to a double-layer steel plate swing wall structure with ductile energy-dissipating components, which can be used for anti-seismic reinforcement of existing buildings and also meet the anti-seismic requirements of new buildings. (2) Background technology [0002] By changing the yield mechanism of the frame structure, the swing wall structure makes the frame deform evenly under a large earthquake, and more plastic hinges appear, which increases the overall energy dissipation capacity of the structure and avoids serious damage to the frame structure locally. The bottom of the swing wall is hinged to the foundation , has little effect on the period of the main structure, and the seismic force is basically unchanged after the swaying substructure is added, but the structural deformation mode can be significantly changed to prevent the very unfavorable structural fa...
