A prefabricated building shock-absorbing structure

Abstract

The invention discloses a prefabricated building shock-absorbing structure, which comprises a wall and a main body steel frame. The top of the wall body is fixedly connected with a return-shaped connector through expansion bolts, and the bottom of the main body steel frame is welded with a first energy-absorbing structure. Steel plate, both sides of the first energy-absorbing steel plate are fixedly connected with sliding blocks, both sides of the inner wall of the return-shaped connector are provided with sliding grooves matching the sliding blocks, and the top of the wall is poured with concrete for the second energy-absorbing A steel plate, the invention relates to the technical field of construction. The shock-absorbing structure of the prefabricated building, through the cooperation of the first energy-absorbing steel plate, the second energy-absorbing steel plate, the stable telescopic rod, the stabilizing block, the connecting block, and the moving groove, is convenient to increase the stability of the main steel frame, making the weight of the main steel frame When it is relatively large, the risk of collapse can be greatly reduced, and at the same time, through the cooperation of the strengthening spring, sleeve, movable column, first magnetic block, and second magnetic block, the main steel frame can be damped to prevent the main steel frame from colliding with the Cracks between walls.

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...
