Description

A prefabricated building structure with shock absorption function

technical field

The utility model belongs to the technical field of prefabricated assembled building structures, and in particular relates to a prefabricated assembled building structure with a shock absorbing function.

Background technique

Earthquake is a general term for the phenomenon of crustal vibration caused by internal force geological action and external force geological action. Buildings are generally built on rock foundations. During an earthquake, the seismic waves propagating in the rock and soil cause the foundation soil to vibrate, especially the vibration in the horizontal direction. , will drive the buildings attached to the surface to produce violent horizontal shaking, thus causing damage to the buildings. In order to cope with strong earthquake disasters, the usual practice is to strengthen the strength and rigidity of buildings, and even build the foundation firmly on the underground rock formation, so that the building and the rock formation form a rigid whole, which belongs to the rigid earthquake-resistant structure, so as to achieve earthquake resistance. Purpose. However, this approach greatly increases the consumption of building materials and increases project costs.

Prefabricated buildings refer to buildings assembled on site with prefabricated components, such that the spliced buildings are less resistant to earthquake waves.
