[0002] The suspended ceiling is a decorative measure that hides all the related professional pipes on the top surface through a layer of false ceiling panels. It exists to ensure the aesthetics of space decoration. With the emergence of new technologies and new materials, people have higher and higher requirements for design effects, technology, construction, and aesthetics. Therefore, the suspended ceiling has become a very important link in interior decoration. The light steel keel gypsum board suspended ceiling is the most widely used suspended ceiling form in decoration at present because of its light weight, non-deformation, easy shaping, and environmental protection.

[0003] However, the existing light steel keel gypsum board ceiling uses 7-shaped or T-shaped integrally cut gypsum boards at the corners, and uses galvanized steel plates for corner reinforcement at the corners. However, due to the influence of temperature or building settlement, the gypsum boards will still deform and crack.

[0004] In this regard, the prior art uses double-layer gypsum boards (i.e., staggered overlap installation), or reinforces the keel structure, such as by riveting or welding, but still cannot solve the problem of gypsum board cracking.

[0005] Therefore, there is an urgent need in the art for a new type of anti-cracking light steel keel gypsum board ceiling to solve the above problems. Utility Model Content

[0009] Preferably, the lower end of the load-bearing keel is provided with a plurality of snap-in grooves;

[0010] The cross sections of the cladding keel and the clamping portion are both U-shaped structures, and a clamping piece is extended inwardly from both free ends of the cladding keel and the clamping portion, and the clamping piece is clamped with the clamping groove.

[0011] Preferably, the suspension rod assembly comprises a plurality of all-wire suspension rods with a diameter of 8 mm.

[0012] Preferably, a seam bandage is provided at the gap between the gypsum board and the adjacent transverse wing board.
