An adaptive sliding rubber bearing and its replacement method

Abstract

The invention discloses a self-adaption sliding rubber support. The support comprises a support body, externally connected steel plates and connection fasteners installed on the externally connected steel plate, the connection fasteners comprise anchoring ribs, sleeves and connecting bolts, the sleeve of each connection fastener which is installed on the corresponding upper externally connected steel plate or the lower externally connected steel plate comprises a movable sleeve body and a fixed sleeve body, the connecting bolt of each connection fastener passes through the corresponding externally connected steel plate of the support and is in threaded connection with the half portion in the corresponding movable sleeve body and the half portion in the corresponding fixed sleeve body, and the outer half portion of each fixed sleeve body is connected with the corresponding anchoring rib. The replacement method of the self-adaption sliding rubber support comprises the following steps: 1, taking the connecting bolts out; 2, chiseling away the movable sleeve bodies and concrete of the layer where the movable sleeve bodies are located; 3, moving the rubber support out, and placing a new rubber support therein; 4, mounting the connecting bolts; 5, adjusting the horizontal elevation, and screwing the connecting bolts tightly; 6, re-pouring concrete. The support is simple in structure, the replacement method is easy to operate, the superstructure is not needed to be jacked up, efficiency is high, cost is low, and high practicability and high economy are achieved.

Description

technical field [0001] The invention belongs to the technical field of special building structure engineering, and relates to a shock-isolation structural component and an installation and replacement method, in particular to a self-adaptive sliding mechanism used for the transition between the upper structure and the foundation of a special building (such as an LNG low-temperature storage tank). Rubber bearings and how to replace them. Background technique [0002] At present, the types of shock-isolation rubber bearings with relatively mature technology used for the connection and transition between the superstructure and foundation of special buildings at home and abroad include: [0003] ①Super high damping rubber bearing; [0004] ② lead core vibration isolation rubber bearing; [0005] ③ High damping rubber bearing, etc. [0006] The above-mentioned support realizes the shock isolation function by shearing rubber deformation, and this type of rubber support has the ...

AI Technical Summary

Problems solved by technology

[0007] 1. Provide the required horizontal displacement through horizontal shearing rubber, and at the same time achieve the shock isolation function. The support and the upper and lower parts of the structure are connected and fixed by connecting plates and connecting bolts. If it needs to be replaced, the upper structure must be lifted to a certain height, and then Remove the connecting bolts, take out the support and the connecting plate, the process is cumbersome, there are many steps, and the replacement of the support is inconvenient;
