Abstract
Description
Technical Field
[0001] The utility model belongs to the field of building construction, and in particular relates to a combined drainage structure for same-floor drainage. Background Art
[0002] Traditional bathroom drainage horizontal pipes and branch pipes need to pass through the floor and be installed below the floor, usually with a suspended ceiling to achieve a beautiful effect. However, it cannot isolate noise at all, and because the density and thickness of the suspended ceiling material are low, it sometimes acts as a resonance membrane and amplifies the sound; at the same time, traditional sanitary ware drainage pipes need to pass through the floor, which increases the probability of water leakage and makes later maintenance difficult.

The drainage horizontal pipes and branch pipes in the bathroom do not need to pass through the floor slab, the degree of damage to the floor slab is low, the sound insulation effect is good, the probability of water leakage is reduced, and the pipeline inspection and maintenance can be carried out on the same floor (home), avoiding the contradiction that the leakage problem caused by the users upstairs needs to be repaired downstairs.
[0004] In order to achieve the above object, the technical solution of the utility model is as follows:
[0005] A combined drainage structure for same-floor drainage comprises a floor drain, a water stop ring, a drainage riser, a drainage branch pipe, a branch pipe water filter, a connecting pipe and a backfill layer. The drainage riser passes through a floor slab, a water stop ring is arranged where the drainage riser passes through the floor slab, a backfill layer is arranged on the floor of the bathroom, a drainage branch pipe and a connecting pipe connected together are pre-buried in the backfill layer, one end of the drainage branch pipe is horizontally connected to the drainage riser, the other end is arranged with a branch pipe water filter, and the other end of the connecting pipe is connected to the floor drain.
[0006] As a supplement to the present invention, the upper surface of the backfill layer is paved with anti-slip bricks.
[0007] As a supplement to the present invention, the anti-slip bricks above the branch pipe water filter outlet are movably arranged.
[0008] As a supplement to the present invention, the drainage riser and drainage branch pipes are HDPE pipes.
[0009] As a supplement to the present invention, the drainage riser and the drainage branch pipe are connected by a socket-and-spigot connection.
[0010] As a supplement to the present invention, the drainage branch pipe and the connecting pipe are firmly connected by using waterproof sealant.
[0011] As a supplement to the present invention, a water filter port is arranged on the connecting pipe, and the water filter port is wrapped with a nylon net.
[0012] As a supplement to the present invention, the drainage branch pipe and the connecting pipe are inclined downward.
[0013] As a supplement to the present invention, the floor drain and the connecting pipe are connected by a threaded sleeve.
[0014] The beneficial effects of the utility model are:
[0015] The utility model has the advantages of simple structure, convenient maintenance, firm connection, reduced noise, significantly reduced risk of leakage, low degree of damage to the floor slab, and ensured the integrity of the building structure. BRIEF DESCRIPTION OF THE DRAWINGS

[0019] The present invention will be further described below in conjunction with the accompanying drawings and specific implementations. It should be understood that the following specific implementations are only used to illustrate the present invention and are not used to limit the scope of the present invention.
[0020] As shown in the figure, the utility model describes a combined drainage structure for same-floor drainage, including a floor drain 1, a water stop ring 3, a drainage riser 4, a drainage branch pipe 5, a branch pipe water filter outlet 6, a connecting pipe 7, and a backfill layer 8. The drainage riser 4 passes through a floor 10, and a water stop ring 3 is arranged at the place where the drainage riser 4 passes through the floor. A backfill layer 8 is arranged on the floor of the bathroom. The backfill layer 8 is pre-buried with a drainage branch pipe 5 and a connecting pipe 7 connected together. One end of the drainage branch pipe 5 is horizontally connected to the drainage riser 4, and the other end is provided with a branch pipe water filter outlet 6. The other end of the connecting pipe 7 is connected to the floor drain 1.
[0021] The utility model discloses a combined drainage structure for drainage on the same floor. The drainage riser 4 passes through the floor 10, and other components are installed on the floor of the bathroom (the floor is lowered). There can be multiple drainage branch pipes 5, which are respectively connected to drainage places (floor drains) such as shower rooms and sinks. When in use, water is discharged from the floor drain to the drainage riser 4, so that drainage on the same floor is achieved. The branch pipe does not need to pass through the floor, the degree of damage to the floor is low, the probability of water leakage is reduced, and better sound insulation effect is achieved.
[0022] The drainage branch pipe 5 and the connecting pipe 7 of the utility model are inclined downward to facilitate drainage.
[0023] Generally, the bathroom floor is paved with anti-skid tiles, that is, anti-skid tiles 11 are paved on the surface of the backfill layer 8, and above the branch pipe water filter outlet 6 are movable anti-skid tiles 12, which can be removed to clean the water filter outlet 6.
[0024] The drainage riser 4 and the drainage branch pipe 5 of the utility model are HDPE pipes, and the drainage riser 4 and the drainage branch pipe 5 are connected by a socket-and-spigot connection.
[0025] The drainage branch pipe 5 and the connecting pipe 7 of the utility model are firmly connected by using a waterproof sealant 2.
[0026] The connecting pipe 7 of the utility model is provided with a water filter port, which is wrapped with a nylon net 9 to prevent the backfill layer 8 from blocking the water filter port.
[0027] The floor drain 1 and the connecting pipe 7 of the utility model are connected by a threaded sleeve, and the height of the floor drain can be adjusted by rotating the sleeve.
