Problems solved by technology

However, after the earthquake, when the energy-consuming core of the support is damaged, the entire support needs to be replaced, and the purpose of repairing the support by replacing only the core mechanism that consumes energy cannot be achieved. Not only is the construction inconvenient, but also a waste of steel, and the repair cost is

Example Embodiment

[0022] In the following, in conjunction with the accompanying drawings, the present invention will be further described by using embodiments as examples:

[0023] As attached figure 1 , 2 As shown, the assembly process of the present invention can be completed in the factory. In the factory, the energy-consuming system is spliced ​​and then welded to the base steel beam. The self-resetting system is assembled in the energy-consuming system, and the tension cable is anchored with anchors. After that, the support processing is completed. Just connect the column and the frame beam on site.

[0024] As attached image 3 , 4 As shown, the energy consumption system of the present invention is completed in the factory during the splicing process. The cross section of the column is H-shaped steel, and the bottom flange is provided with holes, and is connected by welding flange plate I, flange plate II and web plate; on steel plate I There are bolt holes and pin holes. The flange plate I i...

Abstract

The invention discloses a fabricated steel structure H-shaped steel self-reset energy-dissipation supporting device, and belongs to the technical field of structural engineering. The fabricated steelstructure H-shaped steel self-reset energy-dissipation supporting device comprises an energy dissipation system, a self-reset system and a base. A stand column in the energy dissipation system is full-length, and a bottom flange is provided with holes to facilitate passing of a cable. A brass sheet is arranged between two steel plates of the energy dissipation system. The steel plates are connected through bolts. The steel cable penetrates through the energy dissipation system transversely through two end plates to serve as the self-reset system of support. The energy dissipation system and the bolts on the side surface are connected into a whole through a middle pin shaft, and a lever mechanism is formed with the pin shaft as a center, so that transverse displacement of the bottom of thestand column is amplified at the top of the column, meanwhile, deformation of the steel cable is small, and increasing of cable force is not large. In addition, through the fixing function of a preloaded piece, adjusting of the device rigidity can be achieved to meet requirements for resist lateral rigidity and energy dissipation when a building structure is used normally and in a limit state; andusing of H-shaped steel can reduce consumables, and energy is saved.

Description

technical field [0001] The invention designs an assembled steel structure H-shaped steel self-resetting energy-consuming support device, which belongs to the technical field of structural engineering. Background technique [0002] Earthquake, as one of the natural disasters, poses a great threat to the survival and development of human beings, and causes great economic losses. my country is located in the west of the volcanic seismic belt around the Pacific Ocean, and is one of the countries most severely affected by earthquakes in the world. Therefore, the earthquake resistance and disaster reduction of building structures is an important task. The method of resisting earthquakes has developed from the initial earthquake resistance to the current stage of shock absorption. The frame-support structure system is one of the commonly used dual lateral force-resisting structural systems. The support structure can bear most of the horizontal shear force and reduce the horizontal...
