Embodiment 1

[0011] A prefabricated building drainage joint, such as figure 1 , 2 As shown, it is composed of the riser drainage upper interface (1), the riser drainage lower interface (2), the sewage branch pipe connection (3) and the waste water branch pipe connection (4), and each interface is connected to each other; the sewage branch pipe connection (3) is connected to the vertical The sewage connection port (6) of the pipe drainage section (5) is located above the wastewater branch pipe interface (4) and the waste water connection port (7) of the standpipe drainage section (5), and the lower end of the sewage connection port (6) is connected to the waste water connection port (7) ) The height difference h1 at the upper end is 100mm; the angle α between the opening of the sewage branch pipe interface (3) and the horizontal is 2°, and the waste water branch pipe interface (4) has a section of pipe section (9) with the lower outer wall closed and the inner wall connected. The included ...

Embodiment 2

[0013] A prefabricated building drainage joint, such as figure 1 , 2 As shown, it consists of the riser drainage upper interface (1), the riser drainage lower interface (2), the sewage branch pipe connection (3) and the waste water branch pipe connection (4). The height difference h1 at the upper end of the wastewater connection port (7) is 300mm; the angle between the opening of the sewage branch pipe connection (3) and the horizontal angle α is 20°; For the pipe section (9) with an included angle of 70°, the opening direction of the drainage inlet (12) and the horizontal angle β are at 20°, the lowest part of the opening of the drainage inlet (12) of the waste water branch pipe interface (4) is closed with the lower outer wall, The bottom surface distance h2 of the pipe section (9) connected to the inner wall is 60 mm, and the rest are the same as in Embodiment 1.

Embodiment 3

[0015] A prefabricated building drainage joint, such as figure 1 , 2 As shown, it consists of the riser drainage upper interface (1), the riser drainage lower interface (2), the sewage branch pipe connection (3) and the waste water branch pipe connection (4). The height difference h1 at the upper end of the waste water connection port (7) is between 300mm; the opening direction of the sewage branch pipe connection (3) is at an angle α with the horizontal at -20°, and the waste water branch pipe connection (4) has a section of the lower outer wall that is closed and the inner wall is connected. The horizontal and vertical angles are 110° in the pipe section (9), the opening of the drainage inlet (12) is facing the horizontal angle β in -20°, the lowest point and the lower part of the opening of the drainage inlet (12) of the waste water branch pipe interface (4) The bottom surface distance h2 of the pipe section (9) whose outer wall is closed and the inner wall is connected is...

Abstract

The invention provides to an assembled building drainage joint. The assembled building drainage joint is composed of a standpipe drainage upper connector, a standpipe drainage lower connector, a sewage branch pipe connector and a wastewater branch pipe connector which are in mutual communication, wherein the sewage branch pipe connector and the sewage communication opening of a standpipe drainagesection are located above the wastewater branch pipe connector and the wastewater communication opening of the standpipe drainage section; the wastewater branch pipe connector has a pipe section withan enclosed lower outer wall and communicating inner walls; and the drainage inlet of the wastewater branch pipe connector is located above the pipe section with the enclosed lower outer wall and thecommunicating inner walls. The assembled building drainage joint provided by the invention is applied to assembled buildings, solves the problem of needing plate dropping for an assembled integral bathroom, enables installation of a drainage pipeline to be easy and convenient for maintenance and repairing, and has the emergency discharging function of eliminating accumulated water generated by anaccident of water supply and drainage pipelines.

Description

technical field [0001] The invention belongs to the construction field, and the invention relates to a drainage joint, in particular to an assembled building drainage joint. Background technique [0002] At present, prefabricated buildings use prefabricated integral toilets, and the air barrier safety devices for drainage need to be lowered from the floor. When the water supply and drainage pipes leak or burst, the accumulated water cannot be eliminated. Contents of the invention [0003] The content of the present invention is to overcome the defects of the prior art and provide a drainage joint used in prefabricated buildings, which does not need to lower the floor when the air isolation safety device is installed for drainage. [0004] The prefabricated building drainage joint according to the present invention is composed of a standpipe drainage upper interface (1), a standpipe drainage lower interface (2), a sewage branch pipe interface (3) and a waste water branch pi...
