Anti-seismic steel structure

Abstract

The invention belongs to the technical field of steel structures, and particularly relates to an anti-seismic steel structure. The anti-seismic steel structure comprises a base, a mounting plate is arranged at the top of the base, a plurality of fixing screws are fixedly connected to the top of the mounting plate, a supporting plate is arranged between the mounting plate and the base, a plurality of supporting rods are fixedly connected between the bottom of the supporting plate and the base, a plurality of first balls are mounted at the top of the supporting plate, the first balls are tightly attached to the mounting plate, and a plurality of circular plates are arranged on the periphery of the supporting plate. According to the anti-seismic steel structure, by arranging the mounting plate, when a building is blown by wind, the building can drive the mounting plate to horizontally move in the horizontal direction, so that rigid pulling between the building base and the mounting plate is avoided, the building base is protected against breakage, meanwhile, a plurality of second telescopic rods and first springs opposite to the moving direction of the mounting plate can contract, therefore, kinetic energy of the mounting plate is converted into elastic potential energy of the first spring, and the effect of relieving vibration of the building is achieved.

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...

[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
