Description

TECHNICAL FIELD

[0001] The application belongs to the technical field of building, and particularly relates to a beam-column connecting joint of a fabricated building. BACKGROUND

[0002] Building refers to assets artificially built and belongs to the category of fixed assets, including two categories of houses and structures. Houses refer to engineering buildings for people to live, work, study, produce, operate, entertain, store goods and carry out other social activities. Structures are different from buildings and refer to engineering buildings other than houses, such as walls, roads, dams, wells, tunnels, water towers, bridges and chimneys.

[0003] Fabricated building refers to a building that is manufactured by transferring a large amount of on-site work in the traditional construction mode to a factory, processing and manufacturing building components and accessories in the factory, transporting them to the building construction site, and assembling and installing them on the site through reliable connecting methods. Compared with original cast-in-place buildings, the amount of cast-in-place work is greatly reduced, which is beneficial to improve the building construction efficiency.

[0004] In related technologies, when two beams are connected, a corresponding beam sleeve is usually selected as a connecting point. When the beam sleeve connects the cross beam and the longitudinal beam, welding or multiple bolt connection is generally used for installation, so that the cross beam and the beam sleeve are fixed together. However, the structure produced by the traditional method has a single function. For example, when the cross beam needs to be installed and disassembled, it is very troublesome to continuously disassemble multiple bolts. In addition, when the cross beam and the longitudinal beam are connected, there is a lack of a buffer and shock absorption structure. When the beam column is subjected to external force, vibration or collision noise is easily generated.

[0005] For example, the beam-column connecting joint of the fabricated building in the existing Chinese patent No. CN113463772B includes a beam sleeve, a locking mechanism for fastening the beam column is arranged on the beam sleeve, the locking mechanism includes a tightening assembly and a locking assembly for locking the tightening assembly, the tightening assembly is attached to the side wall of the beam column, and a sleeve reinforcing mechanism and a beam column supporting mechanism are arranged on the beam sleeve.

[0006] It can be known that the above cited patent literature also has the same problem. When the cross beam needs to be installed and disassembled, it is very troublesome to continuously disassemble multiple bolts. In addition, when the cross beam and the longitudinal beam are connected, there is a lack of a buffer and shock absorption structure. When the beam column is subjected to external force, vibration or collision noise is easily generated. SUMMARY
