Description

Building shock-absorbing structure

Technical Field

The utility model belongs to the technical field of the building shock attenuation, concretely relates to building shock-absorbing structure.

Background

The earthquake is a general name of the earth crust vibration phenomenon caused by internal force geological action and external force geological action, a building is generally built on a rock-soil foundation, and during the earthquake, earthquake waves propagated in the rock-soil cause the foundation soil body to vibrate, particularly the vibration in the horizontal direction can drive the building attached to the earth surface to generate violent horizontal shaking, so that the building is damaged. In order to cope with a strong earthquake disaster, the common method is to reinforce the strength and rigidity of the building, even to construct the foundation firmly on the underground rock stratum, so that the building and the rock stratum form a rigid whole, which belongs to a rigid anti-seismic structure, thereby achieving the anti-seismic purpose. However, this practice greatly increases the consumption of building materials and increases construction costs.

The prefabricated building refers to a building which is formed by assembling prefabricated components on a construction site, and the spliced building has weak resistance to earthquake waves.
