Description

Technical Field

[0001] This utility model relates to the field of building structure vibration reduction technology, and in particular to a prefabricated masonry assembly vibration reduction and damping device. Background Technology

[0002] Masonry is a common building structure, mainly composed of blocks (such as bricks, stones, blocks, etc.) and mortar (such as cement mortar, mixed mortar, etc.) combined through specific masonry methods;

[0003] To improve the seismic resistance of masonry, shock absorbers are usually installed inside the masonry. However, existing traditional masonry and shock absorption technologies have certain inconveniences in use.

[0004] Defects of traditional masonry structures: On-site masonry mortar joints are prone to being loose, resulting in poor overall wall integrity. Seismic resistance relies on structural columns and ring beams, which are not ductile enough and are prone to brittle failure. Existing damping technology has limitations: Dampers are mostly built into the wall, affecting the building's function and aesthetics. The connection between traditional masonry and dampers is complex, requiring high construction precision. Dampers are difficult to replace after damage, resulting in high maintenance costs.

[0005] To address this, we propose a prefabricated masonry assembly-type vibration damping device. Utility Model Content

[0006] To address the shortcomings of traditional masonry structures in existing technologies, such as the tendency for mortar joints to be loose during on-site construction, resulting in poor overall wall integrity, reliance on structural columns and ring beams for seismic resistance, insufficient ductility leading to brittle failure, and limitations of existing damping technologies (dampers are often built into the wall, affecting building function and aesthetics, complex connection between traditional masonry and dampers, high construction precision requirements, difficulty in replacing damaged dampers, and high maintenance costs), this utility model provides a prefabricated masonry assembly-type seismic damping device.

[0007] The technical solution adopted by this utility model is: a precast masonry assembly-type shock absorption and damping device, including a precast wall, structural beams and structural columns. A damping component is provided in the middle of the precast wall. Precast wall structural columns are fixedly connected to the outer surfaces of both sides of the precast wall. Grooves are provided on the outer surfaces of both ends of the precast wall structural columns. High-strength grouting material is provided on the outer surfaces of both ends of the precast wall. Bolts are fixedly connected to the middle of the grooves. High-ductility mortar is provided in the middle of the precast wall.

[0008] Furthermore, the damping component extends through the middle of the precast wall structural column.

[0009] Furthermore, a grouting sleeve is provided on the top of the precast wall, and one end of the bolt is connected to one end of the structural beam.

[0010] Furthermore, the precast wall structural column is provided with vertical reinforcing bars in the middle, and the vertical reinforcing bars are connected to the precast wall.

[0011] Furthermore, the structural column is fixedly connected to both sides of the structural beam, the damping component is embedded in the middle of the precast wall, and the precast wall structural column and the groove are integrally formed.

[0012] The beneficial effects of this utility model are:

[0013] This utility model uses precast walls with high-ductility mortar inside, which avoids the problem of loose mortar joints during on-site masonry. Precast wall structural columns are added to both sides of the precast wall, and vertical steel bars are added to the precast wall and the precast wall, so that the precast wall structural columns and the precast wall can form an integral load-bearing system. Then, the damping component is fixed at the horizontal joint in the middle of the precast wall during use, which can ensure the aesthetics of the wall, facilitate connection, facilitate construction, facilitate later replacement, and reduce the cost of use.
