Description

technical field [0001] The invention belongs to the technical field of engineering, and relates to a manufacturing method of a built-in magnet type sliding shock-isolation bearing. Background technique [0002] Seismic isolation technology is a kind of structural shock absorption control technology that has been researched and applied maturely. Its basic principle is to install some kind of seismic isolation and energy dissipation device between the upper structure and the lower support or foundation, and move it away from the excellent cycle of the structural system. The excellent cycle of ground motion achieves the purpose of reducing the vibration of the upper structure. Due to its low construction cost, high reliability, simple principle, easy implementation, and good shock isolation effect, it is suitable for structural shock absorption, especially for important buildings and bridges in high-intensity areas, and is the most widely used in the practice of engineering str...

AI Technical Summary

Problems solved by technology

[0004] (1) The laminated rubber isolation system will amplify the long-period component of the seismic wave, and withstand the "hard" shock of the earthquake under the condition of configuring the limit device, and there are also problems with the long-term stability of its own materials;

[0005] (2) Since the sliding friction isolation system has no self-resetting ability, excessive displacement may occur during a large earthquake, and it is difficult to ensure the friction coefficient of the support for a long time at rest;

[0006] (3) The friction pendulum isolation system is easy to cause additional vibration of the structure, and it cannot be completely reset automatically;

[0007] (4) The ball and roller vibration isolation system is a relatively ideal vibration isolation system, but the structure will produce a large lateral displacement during the vibration process;

[0008] (5) Although the seismic isolation effect of the combined seismic isolation system is better than that of a single type of seismic isolation bearing, the design of this seismic isolation bearing system is more complicated and the economy is poor;

[0009] (6) The hybrid isolation system involves a feedback control algorithm with complex logic, and is rarely implemented in projects

[0011] In view of this, traditional seismic isolation bearings have problems such as weak self-resetting ability, significant impact during large earthquakes, and poor tensile performance. It is urgent to develop a new generation of seismic isolation systems
