[0001] The utility model relates to the technical field of building keels, in particular to a high-strength gypsum fiber keel. Background Art
[0002] Keel is a kind of building material used to support the shape and fix the structure. It is widely used in hotels, terminal buildings, passenger stations, stations, theaters, shopping malls, factories, office buildings, old building renovation, interior decoration, ceilings and other places. There are many types of keels. According to different production materials, they can be divided into wooden keels, light steel keels, aluminum alloy keels, steel keels, etc. According to the use part, they can be divided into ceiling keels, vertical wall keels (partition wall keels), floor keels and hanging keels. According to different decoration construction processes, there are load-bearing and non-load-bearing keels (i.e., keels for people to walk on and keels for people not to walk on), etc. After searching, it is found that the typical building keels in the prior art are such as the one disclosed in Publication No. CN206233447U, which includes a main keel, a triangular keel and a hanging piece. The triangular keel is connected to the main keel through the hanging piece. The main keel is a main keel with a "∏"-shaped cross-section. The two lower edges of the main keel are bent inwards to form inner hooks. The hanging piece includes a left piece, a right piece, a front upper piece and a rear upper piece. The front upper piece and the rear upper piece are connected to the main keel through the hanging piece. They are respectively connected between the upper sides of the left piece and the right piece, and a certain distance is left between the front upper piece and the rear upper piece to form an opening. The left piece and the right piece are respectively provided with "convex"-shaped bayonet holes, and the positions of a pair of bayonet holes correspond to each other. The upper sides of the pair of bayonet holes are connected with the openings to form a slot that can be clamped into the triangular keel. Several clamping protrusions are respectively arranged on the outer sides of the left piece and the right piece. The left piece and the right piece of the hanger can be embedded in the cavity of the main keel and the clamping protrusions are respectively clamped on the corresponding inner hook pieces. Its main features are anti-falling and safety.
