Problems solved by technology

[0018] The fire protection scheme and implementation method are all aimed at the vibration-isolation rubber bearing, and there is no scheme for the vibration-isolation friction pendulum bearing; the existing schemes are all suitable for horizontal shear deformation and slight vertical compression deformation, and there is no reliable For example, the technical scheme of the friction pendulum support is characterized by vertical separation and deformation; and the existing scheme cannot meet the special factory needs of the friction pendulum support for temporary fixation, and the temporary fixation can only be released after the on-site assembly and loading are completed. The fire protection scheme combining factory prefabrication and on-site assembly and the realization method of the overall prefabrication, assembly process and fire protection function have not been proposed; although most fire protection schemes can withstand earthquakes, they are prone to wear and tear after earthquakes and have low reliability. It has fire protection, can withstand repeated earthquakes and can still naturally maintain high fire reliability, etc.

Abstract

The invention relates to a function achieving method for a prefabricated assembly type fireproof friction pendulum bearing. A factory prefabrication method for the bearing comprises the steps that a friction pendulum bearing cover plate is fixed below an upper protection device; a friction pendulum bearing chute is fixed above a lower protection device; and a plurality of side fixed plates are fixed along the peripheries of an upper outer fence and a lower outer fence. A site assembly method for the bearing comprises the steps that a prefabricated assembly type fireproof friction pendulum bearing structure prefabricated in a factory is transported to a use site, a lower cover plate and a lower main body structure are fixed, and an upper main body structure and an upper cover plate are fixed; the multiple side fixed plates arranged on the peripheries of the upper outer fence and the lower outer fence are disassembled; two lower fireproof inner sleeves are inserted together in an abutting mode, two lower fireproof outer sleeves are inserted together in an abutting mode, two upper fireproof inner sleeves are inserted together in an abutting mode, and two upper fireproof outer sleevesare inserted together in an abutting mode. The function achieving method for the integrated prefabricated assembly type fireproof friction pendulum bearing can achieve both shock insulation and fire proof function needs for friction pendulum bearings of different carrying capacities, structures and specifications.

Description

technical field [0001] The invention relates to the field of fireproof and seismic isolation products for engineering structures, in particular to a function realization method of a prefabricated and assembled fireproof friction pendulum support, which is used to meet the seismic isolation design requirements of engineering structures such as buildings and bridges and the fire protection of the friction pendulum support itself According to the design requirements, the fire protection part is semi-factory prefabricated and semi-field assembled, which efficiently and reliably meets the requirement that the vibration isolation performance of the friction pendulum support does not degrade under fire or secondary fire after an earthquake. Background technique [0002] In engineering structures (building structures, bridge structures) that currently require seismic design, seismic isolation bearings are usually used between the superstructure and the foundation or between the upper...
