Disc-shaped dentate self-resetting device and application thereof

Abstract

The invention discloses a disc-shaped dentate self-resetting device and an application thereof. The disc-shaped dentate self-resetting device comprises a disc-shaped upper dentate plate, a disc-shapedmiddle dentate plate and a disc-shaped lower dentate plate, wherein occluding teeth are formed on two sides of the middle dentate plate and formed on the inner surfaces of the upper dentate plate andthe lower dentate plate in a corresponding manner; the upper dentate plate, the middle dentate plate and the lower dentate plate are penetrated through by a pre-stressed threaded pipe respectively and are engaged and superimposed together by the connection by nuts cushioned with belleville springs; the upper dentate plate and the lower dentate plate are connected to a building column through extension ends and connecting steel plates, or by connecting to a cantilever truss; and the middle dentate plate is connected to a building girder or the building column through a fixed end plate which sleeves the middle dentate plate. Under the actions of the restoring forces of the belleville springs, the disc-shaped dentate device which deforms after an earthquake is restored to the original state,so that a building can restore quickly after the earthquake; dual breakthroughs are achieved in terms of building appearance maintenance and earthquake resistance; and the device has the advantages of compact design, controllable acting force, wide application range, easy operation, small workload, high reliability, etc.

Description

technical field

[0001] The invention relates to the field of building shock absorption, in particular to a disc-shaped tooth-shaped self-resetting device and its application. Background technique

[0002] In traditional earthquake-resistant buildings, the earthquake-resistant capacity of the structure is mainly improved by adjusting the structural system and increasing the cross-section of beams and columns. Increasing the beam-column cross-section will lead to high stiffness in some areas of the structural system, which will reduce the ductility of the structure, which is not conducive to earthquake resistance and the use of the structure. In addition, after the implementation of these shock-absorbing measures, there is a large residual displacement of the main girder after the earthquake, which cannot restore the structural system to its original state, and it is difficult to meet the requirements for emergency operation after the earthquake.
