An anti-seismic steel structure

Abstract

The invention belongs to the technical field of steel structures, and specifically relates to an anti-seismic steel structure, comprising a base, a mounting plate is provided on the top of the base, a plurality of fixing screws are fixedly connected to the top of the mounting plate, the mounting plate and the base There is a support plate between them, a plurality of support rods are fixedly connected between the bottom of the support plate and the base, a plurality of first balls are installed on the top of the support plate, and the first balls are closely attached to the mounting plate, A plurality of circular plates are arranged around the support plate. The present invention is equipped with a mounting plate, when the wind blows the building, the building can drive the mounting plate to move in the horizontal direction, thereby avoiding the rigid pull between the building base and the mounting plate, protecting the building base from breaking, and simultaneously with the installation The number of second telescopic rods and the first springs opposite to the movement direction of the panel will shrink, thereby converting the kinetic energy of the installation panel into the elastic potential energy of the first spring, thereby playing a role in slowing down the vibration of the building.

Description

technical field [0001] The invention belongs to the technical field of steel structures, in particular to an anti-seismic steel structure. Background technique [0002] Steel structure refers to a structural form that can bear and transmit loads connected by steel plates and hot-rolled, cold-formed or welded profile connectors. The steel structure system has comprehensive advantages such as light weight, factory-like manufacturing, fast installation, short construction period, good earthquake resistance, and fast investment recovery. The unique advantages, so steel structure has a wide range of applications. [0003] Since the steel structure has a certain absorption effect on vibration, the existing steel structure is mainly used to prevent the structure of the building from being damaged by the vibration wave during an earthquake. However, in some windy areas, some buildings with steel frames, such as steel towers , Advertising racks, pillars, etc., not only may be subje...

Problems solved by technology

[0003] Since the steel structure has a certain absorption effect on vibration, the existing steel structure is mainly used to prevent the structure of the building from being damaged by the vibration wave during an earthquake, but in some windy areas, some buildings with steel frames, such as steel towers , advertising racks, pillars, etc., not only may be subject to vibrations from earthquakes, but also more likely to be blown by wind from different directions, so that the connection points of the base are prone to breakage
