[0036] Specifically, in order to facilitate the installation of the closed cavity beam 200, the angle code connecting piece 300 is fixed and installed between the left and right side walls of the closed cavity column 100 and the closed cavity beam 200. When the closed cavity beam 200 is installed on the angle code connecting piece 300 from the inside to the outside, the outer connecting section 301 of the angle code connecting piece 300 is fixed and connected to the outer side wall of the closed cavity beam 200 by the first screw 310, realizing the connection and fixation of the closed cavity beam 200.

[0037] In addition, in order to further improve the stability of the closed cavity beam 200 installation structure on both sides of the closed cavity column 100, the pressing plate limiting piece 400 is used to limit the closed cavity beam 200 from the outside. Specifically, one end of the pressing plate limiting piece 400 is inserted into the H-shaped connecting piece 201 protruding outwardly in the middle of the outer side wall of the closed cavity beam 200, and is locked and connected by the second screw 410. The other end of the pressing plate limiting piece 400 is in abutting connection with the outer connecting section 301 of the angle code connecting piece 300 and the end edge of the outer side wall of the closed cavity column 100, thereby realizing the limiting and fixation of the closed cavity beam 200.
