Abstract

The invention provides a friction pendulum isolation bearing with a liftable device and a construction method thereof. The bearing includes a lower sliding plate, an upper sliding plate and an articulated sliding block. The outer side of the middle of the side wall of the upper sliding plate is provided with a ring of horizontal upper connecting ring plates, the upper connecting ring plates are provided with a ring of upper connecting ring plate bolt holes which are formed at equal intervals, the whole middle of the surface of the upper side of the upper sliding plate is concaved downwards toform a limiting groove, the support further includes a removable device, the bottom of the removable device stretches into the limiting groove and is slidably connected with the limiting groove, the removable device and the upper sliding plate are connected through removable limiting pins pass through the upper connecting ring plate bolt holes, the removable device and the upper sliding plate canbe elastically reset up and down through vertical springs on the removable limiting pins. It can be ensured that the upper sliding plate and an upper buttress are separated vertically when a shock isolation structure encounters strong shock and a friction pendulum suffers from pull force, so that the articulated sliding block and a sliding surface are not separated, and after the upper buttress resets, the friction pendulum can continue to play a role of shock isolation and energy dissipation.

Description

technical field [0001] The invention relates to a friction pendulum shock-isolation support, in particular to a friction pendulum shock-isolation support which prevents a hinged slide block from being separated from a sliding surface and a construction method thereof. Background technique [0002] Friction Pendulum System (FPS) is a widely used seismic isolation device. The main principle of isolation is to use the sliding surface to isolate the structure from the ground, prolong the vibration period of the structure, and filter the seismic energy to the upper structure. For transmission, the arc-shaped sliding surface is used to realize functions such as limit and automatic reset, and at the same time, the sliding friction between the hinged slider and the sliding surface is used to consume seismic energy and reduce the input of seismic force. Therefore, the friction pendulum isolation support system has the advantages of unique isolation principle, simple construction, and...
