Multifunctional drainage stand pipe through floor board integrated device

Abstract

The invention discloses a multifunctional drainage stand pipe through floor board integrated device, and belongs to the technical field of building indoor drainage systems. According to the drainage stand pipe through floor board integrated device, a drainage stand pipe short connection, a ventilation stand pipe short connection, a drainage cross branch pipe connecting opening and a water collecting tank are integrated into a whole, simple inserting connection and independent mounting of a drainage system layer and upper-lower layers of pipelines such as a drainage stand pipe, a ventilation stand pipe, a drainage cross branch pipe and a water proof layer close up are achieved, the multifunctional drainage stand pipe through floor board integrated device has the functions of fast mounting,reliable quality, good odor resistant effect, small occupation space and the like, and the mounting quality and the drainage odor resistant performance are greatly improved. The drainage stand pipe short connection communicates with the ventilation stand pipe short connection through the water collecting tank, balance of directly communicating a drainage cross branch pipe water lock outlet with the ventilation stand pipe, and then communicating with atmosphere is achieved in the integrated device fundamentally, and the technical problem that a floor drain has odor due to closed communication of the drainage cross branch pipe and the drainage stand pipe is effectively solved.

Description

technical field [0001] The invention relates to the technical field of building indoor drainage systems, in particular to an integrated device for multifunctional drainage vertical pipes passing through floors. Background technique [0002] At present, with the development of prefabricated buildings, in order to facilitate the on-site installation of pipelines, reduce on-site wet work, and improve the assembly rate, the high integration of connecting components is particularly important. However, the current actual situation is: (1) All bathroom drainage pipes are spliced ​​on-site pipe sections and pipe fittings (electric welding fusion or bonding), the bonding quality cannot be guaranteed, it is easy to leak, and the construction period is long, which cannot meet the requirements of rapid assembly. , Safe and reliable installation requirements. (2) The installation of the H-shaped double riser is troublesome, the drainage capacity is poor, the distance between the pipes i...

Problems solved by technology

However, the current actual situation is: (1) All bathroom drainage pipes are spliced ​​on-site pipe sections and pipe fittings (electric welding fusion or bonding), the bonding quality cannot be guaranteed, it is easy to leak, and the construction period is long, which cannot meet the requirements of rapid assembly. , safe and reliable installation requirements

(2) The installation of the H-shaped double riser is troublesome, the drainage capacity is poor, the distance between the pipes is large, and the space is occupied; (3) The basic structure of the existing double riser drainage system is that the drainage horizontal branch pipe and the drainage riser of each layer are a closed A connected overall system, the air pressure fluctuation in the standpipe is directly transmitted to the drainage horizontal branch pipe, causing the odor in the standpipe to break through the water seal and enter the room, and the floor drain returns to odor
