Problems solved by technology

[0004] The purpose of the present invention is to overcome the existing technical deficiencies, and propose a steel plate damping wall, which overcomes the problem that out-of-plane buckling easily occurs when the steel plate wall is embedded with a large area, thus causing the steel plate wall to buckle before yielding

Embodiment 1

[0031] see figure 1 (a), figure 2 (a), image 3 As shown in (a), the outer surfaces of the embedded steel plates 11 of the two small cells are respectively provided with a horizontal stiffening plate 4 at the center line, and a vertical stiffening plate 4 is respectively provided at the center line of the inner surface. . The stiffeners 4 on both sides of the steel plates 11 embedded in the two small grids are respectively arranged in an anti-symmetrical "cross-shaped" cross.

Embodiment 2

[0033] see figure 1 (b), figure 2 (b), image 3 As shown in (b), on the outer surface of the two small grid embedded steel plates 11, a stiffening plate 4 is respectively arranged in the direction of the diagonal line, and a stiffening plate 4 is respectively arranged in the direction of the other diagonal line on the inner surface. plate 4. The stiffening plates 4 on both sides of the embedded steel plates 11 of the two small cells are respectively arranged with anti-diagonal lines intersecting.

Embodiment 3

[0035] see figure 1 (c), figure 2 (c), image 3 As shown in (c), two stiffening plates 4 in the horizontal direction and two stiffening plates 4 in the vertical direction are respectively arranged on the outer surface of the steel plate 11 embedded in the two small grids, and the four stiffening plates 4 are partially arranged in the following The center of the small cell embedded steel plate 11 is the inner side of the four corners of the small cell embedded steel plate 11 . There is no intersection between the stiffening plates 4 in the horizontal direction and the stiffening plates 4 in the vertical direction, the two stiffening plates 4 in the horizontal direction are obliquely symmetrical, and the two stiffening plates 4 in the vertical direction are obliquely symmetrical. On the inner side of the two small grid embedded steel plates 11, the number of stiffening plates 4 is the same as the number of stiffening plates 4 on the outer side, and the stiffening plate 4 on t...

Abstract

The invention discloses a steel plate damping wall which comprises an embedded steel plate, an upper horizontal connecting steel plate, a lower horizontal connecting steel plate and flange plates. The upper horizontal connecting steel plate and the lower horizontal connecting steel plate are arranged above and below the embedded steel plate, the flange plates are arranged at the two ends of the embedded steel plate, the embedded steel plate, the upper horizontal connecting steel plate and the lower horizontal connecting steel plate are fixed in a welding mode, the embedded steel plate and the flange plates at the two ends of the embedded steel plates are fixed in a welding mode, and the flange plates, the upper horizontal connecting steel plate and the lower horizontal connecting steel plate are fixed in a welding mode. The steel plate damping wall is characterized in that the embedded steel plate is divided by at least one rigid partition plate into a plurality of small cell embedded steel plate bodies equal or unequal in size, the small cell embedded steel plate bodies and the rigid partition plates are fixed in a welding mode, and reinforcing plates are welded on the side faces of the small cell embedded steel plate bodies. According to the damping wall, in order to solve the problem that the steel plate wall is prone to outward bending due to the large area of the embedded steel plate, the rigid partition plates are arranged to divide the large-area embedded steel plate into the small cell embedded steel plate bodies, the small cell embedded steel plate bodies are respectively independent, and reinforcing ribs are arranged on the small cell embedded steel plate bodies.

Description

technical field [0001] The invention relates to the field of anti-seismic technology of building engineering structures, in particular to a steel plate damping wall. Background technique [0002] The energy dissipation and shock absorption of building structures refers to the installation of appropriate energy dissipation components in the building structure. The energy dissipation components can be composed of energy dissipation and shock absorption devices and supporting components such as braces, walls, beams or nodes. Steel plate shear wall (SPSW) is a new type of anti-lateral force system that effectively supports buildings against wind and earthquake forces. The steel plate damping wall in the present invention is a lateral force-resistant component similar to steel plate shear walls. The steel plate damping wall (hereinafter referred to as: steel plate wall) has great rigidity, yields and dissipates energy in the process of stress, and has the characteristics of super...
