The vertical rigid beam and the horizontal rigid beam are criss-crossed to form a mesh-form rigid beam, which serves to strengthen and protect the boiler water wall. The vertical rigid beam is located between the horizontal rigid beams of the upper and lower layers, and is connected to the horizontal rigid beams of the upper and lower layers by the connecting attachments at the ends thereof. The existing joining method is: at one end of the vertical rigid beam, one groove is welded to the web of the vertical rigid beam and the rib on the horizontal rigid beam; at the other end of the vertical rigid beam, a groove is still used. The steel is welded to the web of the vertical rigid beam, but the ribs on the channel and the horizontal rigid beam are not welded, but the channel is clamped to the ribs of the horizontal rigid beam by a u-shaped steel plate. There is a certain gap between the u-shaped plate and the channel steel to meet the boiler expansion requirements. The disadvantage of this type of connection is that the ribs between the two horizontal rigid beams must be strictly aligned, which is inconvenient to manufacture and install, and is not conducive to boiler pressure transmission.

First, both ends of the vertical rigid beam are properly cut to extend the end of the vertical rigid beam into the horizontal Among the rigid beams. Then, at one end of the vertical rigid beam, the vertical rigid beam and the horizontal rigid beam are welded by two angle steels; at the other end of the vertical rigid beam, the two angle steels and the two angled steels are connected to the horizontal rigid beam and are limited.
