Embedded leakage-proof joint

Abstract

The invention discloses an embedded leakage-proof joint which comprises a joint body, a lower eccentric correction piece, a leakage grate, a grate protection cover, an upper eccentric correction piece and a transverse pipe connection three-way piece. The lower end of the joint body is provided with a lower vertical pipe connector. Multiple fixing feet are fixedly connected to the outer circumference of the bottom of the joint body. An upper connector is arranged at the upper end of the joint body. The lower eccentric correction piece is arranged in the upper connector. The leakage grate is of a crescent structure and arranged in a sealed cavity. The grate protection cover is arranged on the leakage grate. The upper eccentric correction piece penetrates the grate protection cover and a center hole in the leakage grate and is connected with the lower eccentric correction piece. The transverse pipe connection three-way piece is composed of a lower vertical pipe connection opening, a transverse pipe connection opening and an upper vertical pipe connection opening. The embedded leakage-proof joint is reasonable in structure and has the mounting position error adjustment function, the leakage water drainage function and the water seal function, and the mounting effect and the leakage-proof effect are improved.

Description

【Technical field】 [0001] The invention relates to the technical field of building drainage, in particular to a pre-embedded leak-proof joint. 【Background technique】 [0002] At present, there are two ways for building drainage plastic pipes to penetrate the floor: one is to reserve a hole type, that is, to reserve a hole to pass through the floor when the floor is cast-in-place, and to fill the hole after the pipe is installed; the other is to use a The fittings of such pre-buried joints are poured into the floor slab. When installing the pipes, it is only necessary to connect the upper and lower joints with pipes. In the current prior art, no matter the reserved hole type or the pre-embedded joint type, there are disadvantages. [0003] Reserved holes are the most traditional way of piercing the floor. The disadvantages in the application are: the cement in the later filling holes is easy to shrink after drying, and there are small gaps in the parts that are in contact wit...

Problems solved by technology

[0005] The purpose of the present invention is to overcome the above-mentioned deficiencies in the prior art, and provide a pre-embedded leak-proof joint, which aims to solve the technology in the prior art that the leak-proof effect and installation effect of the reserved hole type and the pre-embedded joint type are poor question
