technical field

The utility model belongs to the technical field of buildings and relates to a floor drain for drainage, in particular to a floor drain for drainage on the same floor of a building.

Background technique

Same-floor drainage refers to a drainage method in which the short drainage pipes of sanitary appliances in the bathroom do not pass through the floor, and the horizontal drainage pipes are connected to the main drainage pipe in this floor. Once cleaning and dredging occurs, the problem can be solved in this floor. Because the same-floor drainage technology has the advantages of clear house property rights, unrestricted layout of sanitary appliances, low drainage noise, and low chance of water leakage, it has attracted much attention in the field of construction drainage systems.

The same-floor drainage floor drain is an important component product in the same-floor drainage system. At present, most floor drains on the market use the combination of the floor drain body and the extra trap fittings to realize the functions of drainage, liquid seal and deodorization. The combined installation The height is greater than the thickness of the floor slab. If you want to bury all the traditional floor drains in the floor, you can only partially lower the floor or raise the ground decoration layer to achieve drainage on the same floor, which will increase the difficulty of construction technology and increase the production cost.
