Fabricated building damping structure

Abstract

The invention discloses a fabricated building damping structure. The fabricated building damping structure comprises a wall body and a main body steel frame, wherein a concentric-square-shaped connecting piece is fixedly connected to the upper portion of the surface of the wall body through expansion bolts; a first energy absorption steel plate is welded to the bottom of the main body steel frame;sliding blocks are fixedly connected to the two sides of the first energy absorption steel plate; sliding grooves matched with the sliding blocks are formed in the two sides of the inner wall of theconcentric-square-shaped connecting piece; and a second energy absorption steel plate is poured at the top of the wall body through concrete. The invention relates to the technical field of buildings.According to the fabricated building damping structure, through the cooperation of the first energy absorption steel plate, the second energy absorption steel plate, stable telescopic rods, stable blocks, connecting blocks and moving grooves, the stability of the main body steel frame can be improved conveniently, so that when the weight of the main body steel frame is large, the risk of collapsecan be greatly reduced; and meanwhile, through the cooperation of reinforcing springs, sleeves, movable columns, first magnetic blocks and second magnetic blocks, the main body steel frame can be damped, and cracks are prevented from being generated between the main body steel frame and the wall body.

Description

technical field [0001] The invention relates to the technical field of buildings, in particular to a prefabricated building shock-absorbing structure. Background technique [0002] Prefabricated buildings have the advantages of fast construction speed and less impact on the environment, so they are used more and more in daily life. Prefabricated buildings use concrete wall panels and main steel frames for splicing. Therefore, prefabricated concrete wall panels The joint with the main steel frame is an important part to ensure the strength of the prefabricated building. When the prefabricated building is subjected to external vibrations such as earthquakes, the vibration is transmitted from the ground to the main steel frame, and the main steel frame vibrates accordingly, while the wall panels vibrate. The amplitude is usually smaller than the vibration amplitude of the steel frame, so this also leads to cracking at the connection between the main steel frame and the wall pan...
