[0011] Preferably, the connecting steel plate is a long strip steel plate structure.

[0012] The beneficial effects of this utility model are as follows: This utility model uses connecting steel plates arranged in a manner similar to two channel steels interlocking, with the gaps filled by full welding of heat-resistant steel bars, forming an overall H-shaped structure; openings are made in the upper guard plate of the horizontal flue, and the hangers are fully welded to the square steel to form a U-shaped beam load-bearing structure. The U-shaped beam is then fully welded to the lower plane of the square steel, which facilitates installation and saves construction time. Compared with existing technologies, it is more convenient to install the U-shaped separator, the process is simpler, and the construction period is shorter. Furthermore, the fixing of the connecting steel plates and solid tie rods not only uses welding, but also adds a bolt structure for secondary fixing on the basis of welding.
