[0002] The design of indoor water supply and drainage in buildings is an important part of the entire engineering construction process. The design standard of water supply and drainage in buildings is the technical basis and criterion for designers to design. Correctly understanding and applying the current design standard of water supply and drainage in buildings is the key for designers to design products that meet the quality standards controlled by engineering construction regulations, have a reasonable system and can achieve the expected use function.

[0003] The existing pipe fixing device for fixing small-diameter PVC pipes includes a cement nail, one side of which is fixedly connected to a hook. When in use, the hook is buckled on the outer wall of the PVC pipe, and the cement nail is knocked into the wall to fix the PVC pipe. This type of pipe fixing device has certain technical disadvantages when used; for example, when the PVC pipe is embedded in the wall groove for installation, the groove needs to accommodate the PVC pipe at the same time, and the space is cramped. In this scenario, the installation needs to be completed by vertically knocking the head of the cement nail. Not only is it difficult to control the knocking position, but it is also not easy to control the knocking force to eliminate the gap while not over-squeezing the PVC pipe.

[0004] Therefore, we propose a pipe fixer for indoor drainage pipe construction to improve the above situation. Utility Model Content
