Construction method and supporting device for replacing seismic isolation bearing with cut column of building

Abstract

The invention relates to a construction method and a supporting device for installing shock-isolation rubber bearings on stub columns of buildings. 1) Install the supporting device first, and install the supporting device around the reinforced concrete column of the original structure that needs to be installed with the isolation support; 2) After the support device is installed, cut off the column at the place where the isolation support is installed; 3) Put the The vibration-isolation bearing is put into this position and fixed to complete the installation of the vibration-isolation rubber bearing. The invention applies the shock isolation technology to the existing buildings by using the support system, greatly reduces the cost of reinforcement and reconstruction, effectively improves and enhances the ability of the house to resist earthquakes, and brings a safer, more economical and more environmentally friendly construction for the owners. Way. It makes the old buildings in the earthquake zone have the choice of new reinforcement methods, and also has a more scientific anti-seismic method.

Description

technical field [0001] The invention relates to the technical field of buildings and construction thereof, in particular to a construction method and a supporting device for replacing earthquake-isolation bearings with sectioned columns of buildings. Background technique [0002] The seismic isolation and energy dissipation technology of buildings is accomplished by adjusting the dynamic characteristics of the structure. damaged. Although the technology is still in the stage of continuous development and improvement, so far, many countries such as the United States, Japan, New Zealand and my country have applied the seismic isolation and energy dissipation shock absorption technology to the seismic reinforcement of new buildings, and some have been subject to It has passed the test of actual earthquake and performed well, and the technical and economic benefits are very obvious.

Problems solved by technology

[0003] Earthquake disasters have occurred in many places in my country in recent years, and with the continuous updating of codes, the seismic fortification intensity of buildings has continued to increase. Many old buildings cannot meet the requirements of the current codes. The cost of demolition and reconstruction is too high, and it is not economical and environmentally friendly.

At present, the technology of adding seismic isolation devices to existing buildings has not been reported and applied
