Problems solved by technology

[0003] Since the metal has good hysteresis characteristics after entering the plastic state, and absorbs a large amount of energy during the elastic-plastic hysteresis deformation process, it is widely used to manufacture energy-dissipating shock absorbers of different types and structures. Due to its own structural characteristics and other reasons, there are many problems in the application of common main energy-dissipating metal plate products in the shear wall structure, such as: the installation position of the main energy-dissipating metal plate has a great impact on the building, and the The connection design is difficult, so the main energy-dissipating metal plate is rarely used in the shear wall structure

Embodiment 1

[0024] Such as figure 1 , 2 , 3, the energy-dissipating metal plate of the connecting beam type metal main body includes a main energy-dissipating metal plate 1 (the number of main energy-dissipating metal plates can be multiple, depending on the needs), and the main energy-dissipating metal plate 1 is a shearing The energy-dissipating metal plate of the stress-bearing metal body or the energy-dissipating metal plate of the bending force-bearing metal body. The left and right sides of the energy-dissipating metal plate 1 of the main body are respectively connected with a stiffening plate 3 , and the energy-dissipating metal plate 1 of the main body and the stiffening plates 3 on both sides are connected by welding. The other side of the stiffening plate 3 is connected to an extension plate 2, the extension plate 2 on the left side of the main body energy dissipation metal plate 1 and the extension plate 2 on the right side of the main body energy dissipation metal plate 1 hav...

Embodiment 2

[0026] Such as Figure 4 As shown, in the present embodiment, the extension plate 2 adopts I-shaped steel 21, and the I-shaped steel 21 is vertically welded on the side of the stiffening plate 3. The side of the I-shaped steel 21 has several holes 24, and the holes on the side of the I-shaped steel 21 24 is mainly designed to be able to pass through for the steel bar, and all the other structures are the same as in Embodiment 1.

Embodiment 3

[0028] Such as Figure 5 As shown, in the present embodiment, the extension plate 2 adopts I-shaped steel 21, and the I-shaped steel 21 is vertically welded on the side of the stiffening plate 3. There are several holes 24 on the side of the I-shaped steel 21, and the upper and lower end surfaces of the I-shaped steel 21 are provided with There are studs 25, and the studs 25 are used to strengthen the connection with the main structure wall 5, and the rest of the structure is the same as in Embodiment 2.

Abstract

The invention relates to a metal main body energy-dissipating metal plate provided with a restraining device and a stiffening rib. The metal main body energy-dissipating metal plate comprises at leastone main body energy-dissipating metal plate which is a shear stress type main body energy-dissipating metal plate or a bend stress type main body energy-dissipating metal plate. Stiffening plates are separately connected to the left and right sides of the main body energy-dissipating metal plate and the stiffening plates on two sides are connected by welding, the other sides of the stiffening plates are connected to extension plates, the extension plate on the left side of the main body energy-dissipating metal plate is as same as or different from the extension plate on the right side of the main body energy-dissipating metal plate in structure, the stiffening plates and the extension plates on the same side are placed in a same shear wall coupling beam, and the shear wall coupling beamis connected to a main body structure wall. The metal main body energy-dissipating metal plate can play a role of dissipating seismic energy to protect the main body structure. Meanwhile, as the extension plates are arranged in the metal main body energy-dissipating metal plate and the extension plates are various in form, the metal main body energy-dissipating metal plate is convenient and flexible, simple and practical and good in anti-seismic effect in design application.

Description

technical field [0001] The invention relates to an energy-dissipating and shock-absorbing device for a building structure, in particular to an energy-dissipating metal plate of a metal main body provided with a restraining device and a stiffening rib. 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. The metal energy dissipator is an energy-dissipating shock-absorbing device with superior energy-dissipating performance, simple structure, convenient manufacture, low cost and easy replacement. It can be used as an energy-dissipating unit or a limiting device in conjunction with a seismic-isolation support or a seismic-isolation system, and it can also be used alone in a ...
