Building column-truncating, replacing and seismic-isolating support construction method and supporting device

Abstract

The invention relates to a building column-truncating, replacing and seismic-isolating support construction method and a supporting device. The construction method includes 1), mounting the supporting device, namely mounting the supporting device around an original-structure reinforced concrete column where a seismic-isolating support is needed to be mounted; 2), after the supporting device is mounted, truncating the column at a position where the seismic-isolating support is mounted; 3), disposing the seismic-isolating support in the position to complete mounting of the rubber seismic-isolating support. Seismic isolating technology is applied onto an existing building by utilizing a supporting system, so that cost for reinforcement and reconstruction is greatly lowered, earthquake resistance of the building is effectively improved and enhanced, a mode which is safer, more economical and more environment friendly is brought to proprietors, and a novel reinforcement method solution and a more scientific anti-seismic mode are provided for old buildings positioned in seismic areas.

Description

[0001] technical field [0002] 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 [0003] 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.

AI Technical Summary

Problems solved by technology

[0004] 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
