Abstract

A bidirectional limit mechanism of laminated U-shaped steel plates, belonging to the field of anti-seismic, shock-absorbing and wind-resistant technologies for engineering structures, comprising laminated U-shaped steel plates (1), U-shaped steel plate fixing plates (5), push-pull plates (3), Push-pull groove (6) etc. The push-pull groove (6) is fixed on the upper structure of the shock-isolation layer, and the laminated U-shaped steel plate (1) goes deep into the inside of the push-pull groove, so that the push-pull plate (3) is in the middle of the push-pull groove (6). There is a certain distance between the push-pull plate (3) and the left and right ends of the push-pull groove (6). When the shock-isolation bearing undergoes large deformation, the limiter can limit the deformation of the shock-isolation layer in two directions of push and pull, and play a role in protecting the shock-isolation facilities.

Description

technical field

[0001] The invention relates to a position-limiting mechanism of a shock-isolation structure, which belongs to the field of engineering structure shock absorption and shock-isolation technology, and is mainly used for reducing the deformation of a shock-isolation layer under a large earthquake. Background technique

[0002] The seismic isolation device has the function of prolonging the natural vibration period of the building structure, avoiding the excellent period of the earthquake, and reducing the seismic response of the building structure to a large extent. However, for near-fault earthquakes and other seismic waves rich in long-period pulses, it is easy to cause large deformations in the isolation layer, causing discomfort to people inside the building, and even causing structural instability or damage to the isolation support.

[0003] For such problems, a buffer limit device can be added as a second line of defense. The limit device can be divided i...
