Friction pendulum support assembling method and product

Abstract

The invention discloses a friction pendulum support assembling method. A friction pendulum support comprises a piston, a lower sliding plate arranged below the piston, a wear-resisting plate arrangedon the bottom face of the piston and a spherical stainless steel plate which is arranged on the top face of the lower sliding plate and in sliding fit with the spherical face of the wear-resisting plate; the wear-resisting plate is pressed into a groove in the bottom face of the piston through bending and deformation and abuts against the wear-resisting plate through the side wall of the groove soas to be positioned; the spherical stainless steel plate is pressed into a mounting groove in the top face of the lower sliding plate in a reducing mode and tightly presses the side wall of the mounting groove through elastic restoring force so as to be positioned. According to the friction pendulum support assembling method of the invention, the reliable and efficient assembly of the non-weldedfriction pendulum support is realized; the wear-resisting plate is easier to install and not prone to loosening or falling off; the reliability of the spherical sliding fit of the wear-resisting plateand the spherical stainless steel plate can be improved; the spherical stainless steel plate presses the side wall of the mounting groove so as to be positioned, mounting is easy, the spherical stainless steel plate can be effectively prevented from falling off, and the mounting reliability of the spherical stainless steel plate is improved. The invention further 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
