Anti-pullout device and shock isolation protection method

Abstract

The anti-pull device is installed between the base structure and the superstructure, including a base fixed to the base structure and a top plate fixed to the superstructure and located above the base, characterized in that the base is equipped with a horizontally arranged and rotatable rotating Assemblies, the top plate is equipped with a vertical tensile plate assembly, the tensile plate assembly and the rotating assembly are movably connected, and the upward pulling force of the top plate is transmitted to the base, and the rotating assembly rotates with the horizontal movement of the tensile plate assembly, adapting to the Changes in the direction of horizontal movement of the puller assembly. The invention can generate synchronous horizontal movement with the shock isolation device, and can still provide a large enough tensile bearing capacity when the horizontal displacement between layers is large, thereby reducing the tensile stress on the shock isolation device and protecting the shock isolation device from tensile stress In the case of strong earthquakes, effective tensile protection is provided for the seismic isolation device, and the effectiveness of seismic isolation is improved to prevent the superstructure from overturning. The invention also provides a shock isolation protection method.

Description

Technical field[0001]The present invention relates to a method of anti-pull drawing and isolation protection, belonging to the field of isolation and exploration technology.Background technique[0002]Isolation techniques are becoming more and more widely used in the Gaobia area. The structural system of architecture is getting more complex. The volume increases, and the lower part of the structural layer can have an effective extension of the sputum cycle and overall damping, and the isolation device. Enable a large amount of dissipative ground transmission input energy. In the high-seismic intensity zone, especially the higher-level isolation structure and large isolation structure, in order to achieve a better seismic effect, reduce the horizontal stiffness value of the isolation layer, often lead to excessive displacement of the isolation layer and The problem of zoom in the isolation device is not only difficult to achieve the expected insancing effect, and even the support and s...
