Overall replacement system for original building shock-insulation support and construction method

Abstract

The invention relates to an overall replacement system for an original building shock-insulation support and a construction method. According to an overall replacement system structure, four temporary small foundations fall on a structural foundation and are evenly distributed on the periphery of the shock-insulation support, a section steel column is placed on each temporary small foundation, a steel cushion plate is placed on the top of each section steel column, a jack is placed on each steel cushion plate, another steel cushion block is placed on each jack, each another steel cushion block makes contact with the beam bottom, and it is guaranteed that a stress system is safe and reliable; one oil pressure pump is connected with the four jacks; four reversed beams are evenly distributed on the periphery of a beam column joint of an upper supporting pier of the shock-insulation support. In the replacement process of the shock-insulation support, jacking supporting, monitoring and high-pressure water lossless jet cutting are selected to be performed, and it is guaranteed that the construction process is safe, controllable, efficient, environmentally friendly, easy and fast.

Description

Technical field: [0001] The invention relates to the technical field of structural reinforcement and transformation construction in civil engineering, in particular to an integral replacement system and construction method for an original building's seismic isolation bearing. Background technique: [0002] Shock absorption and isolation technology has been used in the field of housing construction in my country for nearly 20 years. In order to reduce the impact of earthquake disasters, shock absorption and isolation technology has been vigorously promoted in some areas. However, with the development of technology and the improvement of specifications, the first batch of applied seismic isolation structures and isolation support materials cannot meet the requirements of the existing specifications. In order to ensure the safety of the structure, the isolation support of the original structure needs to be replaced. Aiming at the fact that a mature overall replacement method ha...

Problems solved by technology

However, with the development of technology and the improvement of specifications, the earliest batch of applied seismic isolation structures and isolation support materials cannot meet the requirements of the existing specifications. In order to ensure the safety of the structure, the isolation support of the original structure needs to be replaced.

Aiming at the fact that a mature overall replacement method has not yet been formed in the field of housing construction, there is an urgent need for an economical and practical overall replacement method that not only ensures structural safety
