Full-fabricated concrete joint device with replaceable vibration mitigation and isolation device

Abstract

The invention discloses a full-fabricated concrete joint device with a replaceable vibration mitigation and isolation device. The full-fabricated concrete joint device comprises a first connecting piece and a second connecting piece, wherein the first connecting piece and the second connecting piece are connected through a vibration reducing device, a containing groove is formed in the upper end of the first connecting piece, an annular piston is installed in the containing groove, a box body is installed on the inner side face of the annular piston, a partition plate is arranged on the box body, a thread through hole is formed in the inner wall of the containing groove, a bolt is arranged in the thread through hole, a rectangular groove is formed in the inner end face of the bolt, an energy dissipation steel bar is arranged in the rectangular groove, the bottom face of the partition plate is connected to the inner bottom face of the box body through a first spring, the bottom face of the box body is connected to the bottom face of the containing groove through an elastic piece, and the containing groove is filled with hydraulic oil. According to the full-fabricated concrete joint device, vibration energy is consumed through multi-stage vibration reducing, vibration reducing is achieved through the elastic piece and the first spring when the amplitude is smaller, and when the amplitude is larger, a similar self-feedback function is formed at the moment, the function of continuously supporting a building is achieved, an energy dissipation steel bar can be conveniently replaced, and the device can be continuously used.

Description

technical field [0001] The invention belongs to the field of assembled concrete shock-absorbing devices, in particular to a fully-assembled concrete node device with replaceable shock-absorbing and isolating devices. Background technique [0002] With the development of prefabricated buildings, more and more prefabricated concrete buildings are emerging, but shock absorbing devices are generally required to be installed at the connection nodes of prefabricated buildings, but during long-term use, once the shock absorbing devices are damaged , it needs to be replaced in time. Since the shock absorber is damaged, it is too troublesome and inconvenient to operate. Contents of the invention [0003] The invention provides a fully assembled concrete node device with replaceable shock absorbing and isolating devices to solve the defects in the prior art. [0004] The present invention is achieved through the following technical solutions: [0005] A fully assembled concrete no...
