Rope-swing-type self-resetting anti-drawing seismic isolation bearing

Abstract

The invention relates to a rope-swing-type self-resetting anti-drawing seismic isolation bearing. The rope-swing-type self-resetting anti-drawing seismic isolation bearing comprises a U-shaped bearing and a bearing upper plate. The U-shaped bearing and the bearing upper plate are connected through a floating seismic isolation device. According to the rope-swing-type self-resetting anti-drawing seismic isolation bearing, the seismic isolation bearing can isolate seismic oscillation transmitted from different directions through rolling of the roller along a rope and swing of the rope, seismic isolation protection can be provided for an upper portion structure, and damage of the structure is reduced and even avoided; the seismic isolation bearing isolates an earthquake through rolling of the roller along the rope and swing of the rope, and because the starting resistance of rolling and swinging is obviously reduced compared with traditional rubber or a sliding bearing, the seismic isolation efficiency is greatly improved; and the seismic isolation bearing isolates the earthquake through rolling of the roller along the rope and swing of the rope, through rolling of the roller along the rope and free swinging of the rope, the upper portion of the bearing can finally go back to an initial position of the bearing, and the rope-swing-type self-resetting anti-drawing seismic isolation bearing has a good self-resetting function.

Description

technical field [0001] The invention relates to a seismic isolation device for a building or a seismic isolation device for precious cultural relics, in particular to a rope pendulum type self-resetting anti-drawing isolation support. Background technique [0002] Earthquakes cause great damage and loss to people and buildings. The traditional method is to rely on the strength and stiffness of the structure itself to resist earthquakes, and rely on the deformation and damage of structural components to consume the energy introduced into the building. This method is difficult Thoroughly solve various problems faced by earthquake and disaster prevention. [0003] Seismic isolation technology refers to the addition of a flexible seismic isolation layer between the upper part and the lower part, cleverly separating the two, and using the seismic isolation elements in the seismic isolation layer to prevent the seismic energy from being transmitted to the upper building and ensure...

Problems solved by technology

At present, the commonly used seismic isolation bearings mainly have two forms: laminated rubber bearings and friction sliding bearings. However, there are still many defects in the two bearings, such as large starting force, poor fire resistance, and toxic pyrolysis. Gas, poor pull-out resistance and other issues
