Assembly method and product of friction pendulum support

Abstract

The friction pendulum support assembly method, the friction pendulum support includes a piston, a lower sliding plate arranged under the piston, a wear-resistant plate arranged on the bottom surface of the piston, and a spherical stainless steel plate arranged on the top surface of the lower sliding plate and slidingly matched with the spherical surface of the wear-resistant plate , the wear-resistant plate is pressed into the groove on the bottom surface of the piston through bending deformation and positioned against the wear-resistant plate by the side wall of the groove, and the spherical stainless steel plate is pressed into the installation groove on the top surface of the lower sliding plate by reducing its diameter and positioned by pressing against the side wall of the installation groove by the elastic restoring force. The invention realizes the reliable and efficient assembly of the non-welded friction pendulum support, the installation of the wear-resistant plate is simpler, and it is not easy to loosen and fall off, and the reliability of the spherical sliding fit between the wear-resistant plate and the spherical stainless steel plate can be improved. It is positioned close to the side wall of the installation groove, and the installation is simple, which can effectively prevent the spherical stainless steel plate from falling out, and improve the installation reliability of the spherical stainless steel plate. The invention also provides a friction pendulum support.

Description

technical field [0001] The invention relates to an assembly method and a product of a friction pendulum support, which are used for assembling the friction pendulum support. Background technique [0002] Friction pendulum type shock-isolation bearing is a kind of bridge shock-isolation bearing. Through the sliding friction system of the circular arc surface, the design of the sliding surface is used to prolong the overall vibration period of the structure, thereby greatly reducing the vibration caused by the earthquake. The power amplification effect has relatively strong anti-torsion ability, reset ability and good stability. The friction pendulum swings like a pendulum to prolong the natural vibration period of the lower structure to realize the shock isolation function, and consumes the seismic energy through the friction of the sliding interface to realize the shock absorption function. [0003] Friction pendulums can be divided into single-curved surface, double-curved...

AI Technical Summary

Problems solved by technology

Due to the anti-corrosion requirements, the spherical stainless steel plate is mostly made of stainless steel plate, which has limited strength and the risk of deformation and failure. Therefore, it is not surprising that the above-mentioned quality accidents occur, and there is still room for further improvement.

[0004] In the non-welded friction pendulum support with three sliding surfaces, the spherical stainless steel plate on the lower sliding plate slides and cooperates with the wear-resistant plate installed at the bottom of the piston. The wear-resistant plate is installed with screws. In the continuous sliding friction, the wear-resistant plate The screw hole is easily deformed, and the hole becomes larger, which affects the reliability of the spherical sliding fit
