Method for replacing building shock insulation rubber support

Abstract

The invention belongs to the technical field of methods for replacing rubber supports, and discloses a method for replacing a building shock insulation rubber support. The method is mainly technically characterized in that supporting force generated when temporary support bodies are arranged is the same as the design load of the building shock insulation rubber support, then the support is demounted, concrete on the top of a pier column is removed at the same time, a new shock insulation rubber support is jacked through force measurement jacks, the design load is reached, a pier top and pre-buried boards are connected, concrete is poured to the pier top and the pre-buried boards, and finally the temporary support bodies are demounted. By the adoption of the mode of combining column top descending with support jacking, space is provided for replacement of the support, stress evenness of supports for supporting a building is guaranteed, the situation that the structural stress changes due to the fact that one support does not bear force is avoided, needed jacking force of the jacks is small, replacement is quick and safe, and construction cost is low.

Description

technical field [0001] The invention belongs to the technical field of replacement methods for shock-isolation rubber bearings, and in particular relates to a replacement method for building shock-isolation rubber bearings. Background technique [0002] The building isolation rubber bearing is one of the important components in the building isolation engineering. Its function is to isolate the seismic force of the foundation and the superstructure when the earthquake occurs, and protect the building structure from damage when the earthquake occurs. [0003] Since the Wenchuan Earthquake, building shock-absorbing and isolating bearings have been widely used in shock-absorbing and isolating buildings for their superior shock-absorbing and isolating properties. After the support is installed, due to some irresistible factors or human factors, the support is damaged. Due to the heavy weight of the shock-absorbing and isolation building, there are many supports arranged under th...

After the support is installed, due to some irresistible factors or human factors, the support is damaged

Due to the heavy weight of the shock-absorbing and isolation building, the number of supports arranged under the same building cannot be replaced by jacking up the building. If the damaged supports are not replaced in time, the safety of the upper building structure will be endangered.

[0004] When replacing the bridge support, use a jack to jack up the bridge, then replace the new support, and then remove the jack. Because the bridge is light in weight, the beam body will not be damaged when lifting the beam body, and it does not require much Jacks, and building isolation rubber bearings are different, the weight of the building is heavy, the local stress is too large during the jacking process, and it is easy to damage the building, and there is no such a big jack
