Embodiment Construction

[0026] The present invention will be described in detail below in conjunction with the accompanying drawings.

[0027] See figure 2 , which is a flow chart of an embodiment of the method for replacing a shock-isolation bearing of the present invention, which includes the following steps:

[0028] S201, measuring and locating the bolt positions of the upper and lower flange plates of the vibration isolation support to be replaced.

[0029] S202, making a new shock-isolation support, and drilling holes at corresponding positions on the flange plate according to the measured bolt positions.

[0030] S203, jacking up the upper pier of the seismic isolation bearing to be replaced.

[0031] In order to control the possible damage to the upper concrete structure during the jacking process, the jacking height should be strictly controlled not to exceed 1 / 800 of the beam span, that is, the jacking height should not exceed 1 / 800 of the distance between adjacent seismic isolation supp...

Abstract

The invention provides a replacing method of a shock-insulation supporting seat, comprising the following steps of: (1) measuring and positioning the bolt positions of an upper flange plate and a lower flange plate of the shock-insulation supporting seat to be replaced; (2) manufacturing a new shock-insulation supporting seat, and punching on the corresponding positions of the upper flange plate and the lower flange plate according to the measured bolt positions; (3) jacking an upper buttress of the shock-insulation supporting seat to be replaced; (4) pulling the shock-insulation supporting seat to be replaced out of an original position; (5) carrying the new shock-insulation supporting seat to an installation position, and installing and fixing; and (6) unloading the jacked upper buttress. The replacing method has the advantages of low cost, easy and convenient operation, safety, reliability and greatly-shortened construction period.

Description

technical field [0001] The invention relates to a building shock-isolation technology, in particular to a method for replacing a shock-isolation support. Background technique [0002] Earthquake is one of the most serious natural disasters faced by human society. "Earthquake disaster mitigation" has become a worldwide concern, especially the "5.12" Wenchuan Earthquake, which caused a huge loss of property and people's lives. The research, development and application of seismic technology have brought great urgency and necessity. Rubber pad seismic isolation technology is a popular new engineering anti-seismic technology in the world. It places the vibration isolation and energy dissipation device (rubber isolation support) between the bottom of the structure and the foundation (or the top of the bottom column), and the upper structure and the top of the bottom column. The base is "spaced apart". In this way, the dynamic characteristics and dynamic effects of the structure ...
