Abstract

The invention relates to an energy consumption and shock absorption device between a joint and a cross beam, and belongs to the technical field of building shock resistance. The energy consumption andshock absorption device comprises a first connecting portion, a second connecting portion and a rotating shaft. The first connecting portion and the second connecting portion are rotatably mounted together by the rotating shaft. The first connecting portion comprises a first fixing block and two first protruding blocks fixed to the first fixing block. The second connecting portion comprises a second fixing block and a second protruding block fixed to the second fixing block. The two first protruding blocks and the second protruding block are arranged from from to rear. One part of the secondprotruding block is located between the two first protruding blocks. Dampers are arranged between the second protruding block and the first protruding blocks. A damper is arranged between the second protruding block and the first fixing block. The rotating shaft penetrates through the second protruding block and the two first protruding blocks. The first fixing block is fixed to the joint. The second fixing block is fixed to the cross beam. The energy consumption and shock absorption device has excellent damping energy consumption effects.

Description

technical field [0001] The invention relates to the technical field of anti-seismic buildings, in particular to an energy-dissipating shock-absorbing device between nodes and beams. Background technique [0002] Earthquake disasters have been one of the most serious natural disasters faced by human beings since ancient times. They are extremely random, unpredictable and widely spread, and seriously threaten human survival and social development. Frequent strong earthquakes in recent years have caused massive damage to building structures, resulting in a large number of casualties and property losses. [0003] Based on the research status of energy dissipation and shock absorption of prefabricated structures at home and abroad, it can be seen that due to its own limitations, the energy dissipation capacity of prefabricated structures under earthquakes has certain limitations. Therefore, in order to improve the seismic performance of prefabricated structures , the introductio...
