Multi-dimensional energy-dissipation shock-absorption device for storey-adding structure

Abstract

Provided is a multi-dimensional energy-dissipation shock-absorption device for a storey-adding structure. The device comprises an aluminum oxide ceramic particle friction pad layer, a U-shaped low-yield-point metal damper, a sliding rail, a rigidity layer, a storey-adding building outer wall, anchor bolts, a storey-adding building and an original building outer wall. An original building is a building before the storey-adding building is added. The multi-dimensional energy-dissipation shock-absorption device has the advantage of multi-dimensional earthquake resistance, the aluminum oxide ceramic particle friction pad layer is used for resisting the seismic action in the horizontal direction, and the U-shaped low-yield-point metal damper can be used for resisting the seismic action in the vertical direction and the torsion direction; a novel friction material is adopted, and aluminum oxide ceramic has the advantages of being high in hardness, excellent in abrasion resistance, low in weight, low in cost, simple in structure, convenient to construct, low in price and the like.

Description

technical field [0001] The invention relates to a multi-dimensional energy-dissipating shock-absorbing device for a layered structure, belonging to the field of anti-seismic and shock-absorbing building structure engineering. Background technique [0002] With the rapid development of my country's economic construction, urban land resources are becoming more and more tense, while the requirements for the space and functions of buildings are getting higher and higher. Adding floors to existing buildings is an effective way to solve this problem. It can be roughly divided into four categories: direct layering, coat layering, indoor layering, and underground layering. It has the advantages of less investment, no additional land occupation, and saving urban allocation fees. Adding floors to existing buildings has practical significance in alleviating the shortage of urban construction land and improving people's living conditions. It is an urban architectural renovation plan t...

AI Technical Summary

Problems solved by technology

[0003] However, a large number of existing houses or added-story structures have insufficient seismic performance, and may be damaged or collapsed under the action of an earthquake.

For building structures that need to add floors, they are generally reinforced after adding floors, but the current reinforcement methods are mainly to strengthen columns or thicken walls, which consume a lot of manpower and material resources, and do not reasonably and effectively improve the seismic capacity of the structure

Existing structural energy dissipation and shock absorption technologies, such as tuned mass method and damper energy dissipation method, are costly and occupy the space of existing buildings, lacking in practicality and convenience. Therefore, it is necessary to explore new and economical methods combined with existing technologies And effective multi-layer shock absorption technology
