Technical Field

[0001] The utility model belongs to the technical field of building decoration, and particularly relates to an anti-cracking system for wrapping water supply and drainage pipes. Background Technique

[0002] During building decoration, the vertical pipes of sewer pipes or water supply pipes are wrapped with decorative materials to play a decorative role. There are various specific structures. For example, one is to use red bricks or lightweight bricks to wrap the vertical pipes, but the pipe wrapping with brick structure is relatively thick and takes up space. The other is to use a dragon skeleton as a framework, and install plywood on the surface of the dragon skeleton to enclose the vertical pipe. In order to further improve the service life of the dragon skeleton, light steel keels are used as supports, which have a long service life and structural stability.

[0003] In the plywood pipe wrapping structure, the plywood is fixedly installed on the surface of the light steel skeleton through bolts. The integrity of the connection between two adjacent plywoods is poor. After long-term use, the gap between the two plywoods gradually increases, resulting in cracks in the connection between the plywoods, further reducing the overall stability of the pipe wrapping. Therefore, an anti-cracking system for wrapping water supply and drainage pipes is needed, which can reinforce the connection between two plywoods, thereby improving the integrity of the connection between the plywoods, preventing the occurrence of cracks at the connection of the plywoods, and further improving the overall structural stability of the pipe wrapping.
