Multilayer bridge overhanging quake-isolation structure

Abstract

The invention relates to the field of covered bridge buildings, and particularly relates to a multilayer bridge overhanging quake-isolation structure, by virtue of which a covered bridge can obtain an excellent quake-isolation effect. The multilayer bridge overhanging quake-isolation structure comprises a single building body, a left auxiliary single body and a right auxiliary single body; a deformation joint is formed between a mudsill and a left mudsill, and between the mudsill and a right mudsill; a quake-isolation support structure is arranged below each of the deformation joints at the two ends of the mudsill. A covered bridge mudsill is divided into three segments, namely the mudsill, the left mudsill and the right mudsill; the deformation joints are additionally formed between the mudsill and the left mudsill, and between the mudsill and the right mudsill, so that buffer gaps are provided for the deformation of the covered bridge caused by earthquakes and the like; besides, the quake-isolation support structures are arranged below the deformation joints, so that the impact of earthquakes on the covered bridge is overcome and a very firm building foundation is provided for the building part on the covered bridge. The multilayer bridge overhanging quake-isolation structure is applicable to bridge buildings represented by the covered bridge.

Description

technical field [0001] The invention relates to the field of corridor bridge construction, in particular to a multi-storey bridge overhanging shock-isolation structure. Background technique [0002] Most of the current bridge structures are single-story, and two-story bridge structures are relatively rare. There is no precedent at home and abroad for a modern corridor bridge that can meet the functions of flood discharge, pedestrian traffic, vehicle traffic, viewing, dining, entertainment, etc. at the same time. Classical covered bridges mostly adopt the brick and wood arch bridge type. With the continuous improvement of the social and economic level, people's requirements for the function of corridor bridges are also constantly improving. It is hoped to build a modern corridor bridge that has traditional cultural characteristics and can meet the functions of flood discharge, pedestrian, vehicle, viewing, dining, entertainment and other functions. However, the design of la...

AI Technical Summary

Problems solved by technology

However, the design of large-scale comprehensive covered bridges is restricted by various conditions such as terrain and flood discharge, and the structure is very complicated. At present, there is no similar architectural form at home and abroad.

[0003] In particular, since the span of covered bridges is generally large, if too many expansion joints in traditional construction methods are used, it will be difficult to ensure the stability of the buildings on the bridge

If the necessary expansion joints are not used, it cannot be ensured that the covered bridge can absorb the impact of the earthquake, resulting in damage to the covered bridge
