Special connector for ventilation of high-rise building

Abstract

The invention provides a special connector for ventilation of a high-rise building, which comprises a collecting box. The collecting box consists of a box body and a box cover arranged at the upper part of the box body. The box cover is provided with an upper drainage orifice and an upper ventilating orifice. A lower drainage orifice and a lower ventilating orifice are arranged at the bottom of the box body. An upper drainage pipe connecting pipe, an upper ventilating pipe connecting pipe, a lower drainage pipe connecting pipe and a lower ventilating pipe connecting pipe are respectively arranged corresponding to the upper drainage orifice, upper ventilating orifice, the lower drainage orifice and the lower ventilating orifice. The box cover, the upper drainage pipe connecting pipe and the upper ventilating pipe connecting pipe form a connecting box cover injection moulded at one time. The box body, the lower drainage pipe connecting pipe and the lower ventilating pipe connecting pipe form a ventilating box body injection moulded at one time. The special connector for ventilation of the high-rise building has the advantages of small occupied space, good ventilating effect, easiness in production and construction, and low cost.

Description

technical field [0001] The invention relates to a building connector, in particular to a special connector for high-rise building ventilation. Background technique [0002] Existing high-rise residential drainage systems mostly use double-standpipe drainage systems. This drainage system requires that the special ventilation pipes and drain pipes must be connected in separate layers or layers. The connecting parts used are H-type special connecting parts or two inclined Tee connection; due to the installation operation and pipe fitting spacing requirements, the distance between the centers of the two drain pipes and vent pipes with a diameter of 110mm shall not be less than 250mm. [0003] During the application, it was found that the current design and installation method has the following problems: 1. It takes up a lot of space: the drainage pipe and the ventilation pipe need to occupy a space of 300mm wide and 500mm long, and with the decoration and package columns, it wil...

AI Technical Summary

Problems solved by technology

[0003] During the application, it was found that the current design and installation method has the following problems: 1. It takes up a lot of space: the drainage pipe and the ventilation pipe need to occupy a space of 300mm wide and 500mm long, and with the decoration and package columns, it will occupy a building area of ​​0.2 square meters. This makes the bathroom appear more crowded

2. The exhaust effect is not good: the water flows vertically in the standpipe, which belongs to gravity drainage, that is, the water flows downward along the pipe wall, and the entire pipe wall will form a water film. At present, the H pipe is connected in the middle of the standpipe layer. If the pipe wall at the connection is disconnected, an inertial water film or water curtain will be formed, which is not conducive to the gas entering the vent pipe from the connecting pipe, thereby affecting the exhaust effect

3. It is difficult to construct the waterproof layer where the double riser pipe passes through the floor, and it is easy to leak: due to the short distance between the two pipes, the waterproof layer in the middle of the two pipes is very difficult to construct, and it is often an area with frequent leakage; For toilets with drainage, it is more difficult to construct the part where the double riser passes through the floor, and it is the main part of the water seepage in the interlayer
