Elevation difference type seismic isolation structure of building and surrounding site of building

Abstract

The invention relates to an elevation difference type seismic isolation structure of a building and a surrounding site of the building in the field of construction engineering. According to the technical scheme, the elevation difference type seismic isolation structure includes a seismic isolation joint, and a first civil engineering component and a second civil engineering component which are located on both sides of the seismic isolation joint, the first civil engineering component overhangs a first bridging piece in the direction of the seismic isolation joint in a cantilevered mode, spans the seismic isolation joint, and is placed on the upper part of the second civil engineering component, and the width of the first bridging piece satisfies the maximum deformation width covering the seismic isolation joint; and a gap is left between the first bridging piece and the second civil engineering component, and the gap is filled with a flexible material. According to the elevation difference type seismic isolation structure, the safety of the seismic isolation joint of the building and the surrounding site of the building is fully ensured, various complex working conditions are adapted, the usual normal use function of the building and the surrounding site of the building is met, normal use of the building and the surrounding site of the building and quick maintenance after the earthquake can still be ensured when the larger earthquake occurs within the design intensity range, and meanwhile, the advantages of universality and standardization are achieved.

Description

technical field [0001] The invention belongs to the field of construction engineering, and in particular relates to various complex seismic isolation joint structures in the seismic isolation design of buildings and surrounding sites. Background technique [0002] The structure of the isolation joint of the building and its surrounding sites, as the most critical connection node between the isolation area and the non-seismic isolation area in the seismic isolation design of the building and its surrounding sites, not only needs to meet the normal conditions of the building and its surrounding sites. Use function; meet the conventional temperature deformation and civil settlement of the building and its surrounding sites; especially when a relatively large earthquake within the design intensity range occurs, it can still effectively guarantee the normal use of the building and its surrounding sites and rapid maintenance after the earthquake . [0003] At present, seismic iso...

Problems solved by technology

However, the existing conventional seismic isolation joint structure based on the traditional seismic theory can only meet the daily temperature deformation and civil settlement, and cannot deal with the hazards of earthquakes of greater intensity, and cannot meet the urgent requirements of the rapidly developing seismic isolation technology. Disorganized and obvious defects, resulting in increased project costs and numerous quality risks
