An earthquake-resistant prefabricated house

Abstract

The invention discloses an anti-seismic fabricated house and relates to the technical field of fabricated houses. The prefabricated house comprises stand columns, a base, prefabricated wallboards anda roof cover. Buffering mechanisms with buffering and damping effects is installed between the stand columns and the base. Each buffering mechanism comprises a supporting base, a hemisphere fixedly arranged on the supporting base, a connecting board integrally arranged on the corresponding stand column and a damping device arranged between the supporting base and the base, an installing groove isformed in the base, the supporting base and the connecting board are arranged in the installing groove, a plurality of damping springs are arranged between the connecting board and the groove wall ofthe installing groove, a spherical groove is formed in the connecting board, the hemisphere is rotationally arranged in the spherical groove, a plurality of balls are arranged between the groove bottom of the installing groove and the supporting base in a rolling mode, and a plurality of supporting springs are arranged between groove openings in the two sides of the base and the corresponding stand column. The fabricated house has the advantage of stable damping in multiple directions, and the safety and stability of the fabricated house are improved.

Description

technical field [0001] The invention relates to the technical field of prefabricated houses, more specifically, it relates to an anti-seismic prefabricated house. Background technique [0002] Prefabricated houses have been vigorously developed in recent years. The construction process is generally completed in factories and then assembled on the foundation; however, earthquakes have caused serious damage to various building structures, especially prefabricated houses. Seismic isolation technology is a technology that has developed rapidly in the field of earthquake resistance in the past 30 years and has been continuously improved. It is currently mainly used in the field of building structures. [0003] When the magnitude of the earthquake is large or the "hard resistance" of the structure is difficult to meet the expected seismic requirements due to some reasons, the use of seismic isolation technology to reduce the input seismic energy of the structure can achieve good r...

AI Technical Summary

Problems solved by technology

[0004] There is a risk of earthquakes in many areas, so the houses in these places need to have earthquake resistance. When the house is impacted by the vibration, the beam will be subjected to a lot of force. Most of the reinforced beam feet used for earthquake-resistant houses on the market currently have shock absorption effects. Poor, and can only absorb shocks in one direction, so it is difficult to prevent vibrations caused by unknown sources, and it is easy to cause the house to collapse
