[0021] Please refer to Figure 1 、 Figure 2 and Figure 3 Steel column 2 and steel beam 1 are temporarily fixed through single connecting plate 4 and mounting bolt 5;Horizontal net hook 9 is arranged on steel beam 1;Structural joint plate 6 is arranged at the end of lower flange haunch board 3;Web full penetration weld 7 and upper and lower flange full penetration weld 8 are used as the measures of equal strength connection of steel beam 1 and steel column 2, lower flange haunch board 3 has the ability of improving the shear capacity of the end of steel beam 1, structural joint plate 6 is arranged at the end of lengthened lower flange haunch board 3, so that structural joint plate 6 has the function of avoiding instability, without setting other anti-seismic measures such as gusset, saving engineering quantity, and not affecting building space, horizontal net hook 9 is arranged on steel beam 1, can hang horizontal net, is used as the safety protection of construction, avoids high-falling accident, steel column 2 and steel beam 1 are temporarily fixed through single connecting plate 4 and mounting bolt 5, and web full penetration weld 7 and upper and lower flange full penetration weld 8 are used as the measures of equal strength connection of steel beam 1 and steel column 2.

[0022] The working principle of this utility model:

[0023] Using multiple handles 12, two steel columns 2 are placed in the desired location, leaving a gap between them for the steel beam 1. The steel beam 1 is then placed within the gap and aligned with both the steel beam 1 and steel column 2 using a single connecting plate 4. Simultaneously, the fixing plate 10 is aligned with the steel column 2. Multiple clamping bolts 11 are then moved within the fixing plate 10, causing one end of each clamping bolt 11 to connect with the steel column 2. This strengthens the connection between the steel beam 1 and steel column 2, preventing easy detachment and further reinforcing the structure. The full penetration weld 7 in the web and the full penetration welds 8 in the upper and lower flanges serve as a strong connection between the steel beam 1 and steel column 2. The single connecting plate 4 is then bolted together using multiple mounting bolts 5. These mounting bolts 5 are only for temporary fixation during the process and are not permanent structural load-bearing; they can be removed and reused. When disassembling the steel beam 1 is required, the multiple clamping bolts 11 are first moved, followed by the multiple... The installation bolts 5 separate the multiple clamping bolts 11 from the steel column 2, thereby eliminating the need for reinforcement between the fixing plate 10 and the steel column 2. By screwing the installation bolts 5, the single connecting plate 4 can be disassembled simultaneously, facilitating the movement of the steel beam 1 between the two steel columns 2. This further facilitates the user's separation of the steel beam 1 from the two steel columns 2. The installation of multiple horizontal safety net hooks 9 provides additional safety protection for workers at height. Even if a person accidentally falls, the safety net can effectively catch the falling person, preventing direct fall to the ground and reducing injury. Moreover, the horizontal safety net hooks 9 can be flexibly installed according to the specific conditions of the construction site, adapting to different building structures and construction environments. Installation is simple and convenient, and deployment can be done quickly. Compared with other complex safety protection measures, the installation and maintenance costs of the horizontal safety net are relatively low, and it can effectively prevent falls from height, reducing downtime and compensation losses caused by accidents.
