Description

Technical Field

[0001] This utility model relates to the field of beam-column connection structures in prefabricated buildings, and more specifically, to a beam-column connection structure for prefabricated buildings. Background Technology

[0002] Currently, steel structure buildings are widely used. Steel beams and columns are prefabricated in the factory and transported to the site for assembly. Compared with reinforced concrete structures, which require molding, pouring, and curing, this can effectively shorten the construction cycle. In addition, steel structure buildings can effectively reduce on-site wet work, resulting in significant environmental benefits. However, steel structures often require beam-column connectors for fixing during installation and assembly.

[0003] In traditional technologies, such as the connector for a fully prefabricated prestressed concrete beam-column assembly (application number CN202020234681.9), this utility model can achieve dry connection of prefabricated frame nodes, reduce on-site wet work, enhance node performance, and dissipate and replace energy through ductile energy dissipators. However, this invention still has drawbacks in use: it is relatively complex to assemble and install multiple beams and columns laterally, and the installation often takes a long time, thus delaying the construction period. Therefore, existing technologies have been researched and improved to address the shortcomings of traditional structures and provide connectors, which can achieve a more practical purpose.

[0004] A beam-column connector, as disclosed in authorization announcement number CN219033537U, relates to the field of beam-column connector technology. It includes a main connecting sleeve and a support mechanism. The main connecting sleeve has an installation mechanism for connection and fixation at its inner center. The support mechanism for stable support is installed on both sides of the bottom of the main connecting sleeve. The main connecting sleeve also has a fixing mechanism for overall fixation at its inner center. This beam-column connector...

[0005] Compared with existing devices, the above-mentioned patent can pre-fix the main connecting sleeve with the pipe column by means of a fixed plate and threaded column. At the same time, the threaded column is installed in multiple sets through type, which can ensure the overall firmness between the main connecting sleeve and the pipe column, so as to facilitate the subsequent beam and column installation and connection. By means of extension plate and movable seat, the support frame can be rotated and adjusted, and then fixed to the lower surface of the steel beam by fixed seat. This can support and lift the lower end after the steel beam is connected to share the pressure, which helps to ensure the stability of the steel beam installation.

[0006] However, in the aforementioned prior art, the connecting sleeve is independently fixed to the steel beam using an external support frame mechanism. When it is fixed, the force-bearing area of ​​the frame structure is small, and the support area is small when supporting the steel beam, resulting in poor stability after fixing. Utility Model Content

The longitudinal beams and columns are connected at the upper and lower ends of the connection sleeve, and the transverse beams and columns are connected inside the connection sleeve. The force-bearing ends are completely supported on the inner side of the connection sleeve, and are fixed in one piece. They are then fixed by through bolt members and locked with external bolts. The structure has strong fixing firmness, a large force-bearing support area, and is firmly fixed after fixing.
