Directly connected drainpipe floor drain and its installation method

Abstract

The invention provides a floor drain structure directly connected with a drain pipe and an installation method of the floor drain structure. The floor drain structure is placed in reserved drainage pipe holes of a floor slab structure in a penetrating mode; the floor drain includes a body and a support structure, the upper port and lower port of the body are communicated with an upper-portion drainage pipe and a lower-portion drainage pipe respectively, and the peripheral face of the middle section of the body is provided with a drainage gate opening extending in the axial direction of the cylindrical shape of the body; the support structure is arranged on the peripheral side of the drainage gate in a surrounding mode and located in the reserved drainage pipe holes of the floor slab, the bottom edge of the annular peripheral wall of the support structure is provided with an annular bottom wall, a water inlet of the floor drain is formed between the top edge of the annular peripheral wall and the body, and the annular peripheral wall, the annular bottom wall and the body are defined to form an annular drainage space. By the technological means, opening of a traditional floor drain position of the floor slab can be avoided, and the number of horizontal connection pipes between the traditional floor drain and the drainage pipes is reduced, the construction cost is reduced, the construction process is reduced and the construction progress is sped up.

Description

technical field [0001] The invention relates to the technical field of building construction, in particular to a floor drain directly connected to a drainage pipe and an installation method thereof. Background technique [0002] On the ground of traditional outdoor balconies with drainage requirements, a floor drain must be installed, and there is a certain distance between the floor drain and the drain pipe. Corresponding pipes must be used to connect the floor drain and the drain pipe to form a complete drainage system. To use this method for drainage, it is necessary to open corresponding holes for floor drains on the floor and holes for drain pipes to pass through the floor. If the waterproof construction of the location is a little careless, it is more likely to cause water seepage on the floor. Contents of the invention [0003] In view of the above situation, the present invention provides a floor drain directly connected to the drain pipe and its installation meth...
