Pre-buried anti-leaking connector system

Abstract

The invention discloses a pre-buried anti-leaking connector system for draining off water of a same layer for building decoration. The pre-buried anti-leaking connector system comprises a telescopic joint and anti-leaking connectors, wherein a pipeline at the upper end of the telescopic joint is connected with an upper-layer anti-leaking connector; a pipeline at the lower end of the telescopic joint is connected with a lower-layer anti-leaking connector; the telescopic joint comprises an upper telescopic joint cover, a middle cup body, a lower cup body, a waterproof rubber ring and a telescopic pressing ring; the lower cup body of the telescopic joint sleeves the pipeline at the lower end; the middle cup body of the telescopic joint sleeves the pipeline at the upper end; the upper telescopic joint cover, the middle cup body and the lower cup body are connected in sequence; the anti-leaking connectors comprise an anti-leaking connector body and a different diameter connecting part; a water guide groove is formed in the upper end of the anti-leaking connector body; a drain hole is formed inside the anti-leaking connector body; a fixing ring is arranged at the lower end of the anti-leaking connector body; fixing feet are arranged on the fixing ring; fixing holes are formed in the fixing ring; the different diameter connecting part is connected with the anti-leaking connector body; the eccentricity degree of the different diameter connecting part is minus 10mm to 10mm. The pre-buried anti-leaking connector system is good in anti-leaking property, convenient to mount, high in pressure bearing property, good in air tightness and high in security.

Description

technical field [0001] The invention relates to a drainage pipe, in particular to a pre-embedded leak-proof joint system. Background technique [0002] Same-layer drainage is more and more widely used in modern buildings, and it will become the trend of building drainage in the future. At present, in the construction process of civil construction, equipment installation, decoration construction and other constructions, the descending plate type drainage is secondary installation because holes are reserved before secondary construction and installation of pipes and fittings. The joints have no water seal and no secondary drainage function. , during the construction process, it is necessary to drill holes on the pipe fittings and install them. The method of backfilling and pouring concrete in the secondary construction is adopted. The operation is cumbersome and the installation is inconvenient.

Problems solved by technology

At present, in the construction process of civil construction, equipment installation, decoration construction and other constructions, the descending plate type drainage is secondary installation because holes are reserved before secondary construction and installation of pipes and fittings. The joints have no water seal and no secondary drainage function. , during the construction process, it is necessary to drill holes on the pipe fittings and install them. The method of backfilling and pouring concrete in the secondary construction is adopted. The operation is cumbersome and the installation is inconvenient. Water seepage in the external filling layer at the place and around the vertical pipe of the floor tiles is generally used to deal with water seepage. Water seal leak-proof joints are generally used to deal with water seepage. Improper treatment will form stinky puddles due to water saturation or leak to the next floor or overflow to other floors in this floor. Indoors, non-water-sealed leak-proof joints are also used, and the water flow is not smooth; the installation between two adjacent floors is inconvenient due to the eccentricity of the pipe center

The positions of the upper and lower pipes between the floors have been fixed, and the connection between the upper and lower pipes is generally connected by telescopic joints. At present, the upper cover of the telescopic joints, the waterproof rubber ring, the middle cup body, and the lower cup body are installed in sequence in the market. The cup body under the expansion joint is covered with the upper and lower end pipes, and then the middle cup body of the expansion joint is put on the upper end pipe, and then the middle cup body of the expansion joint and the lower cup body of the expansion joint are sleeved together by using the expansion area at the lower end of the expansion joint, which is waterproof The inner and outer diameters of the apron are the same as the inner and outer diameters of the upper cover of the expansion joint, and there is a hidden danger of water leakage in the pipeline. The length of the lower pipe inserted into the expansion joint is not enough, and the insertion depth of 48mm does not meet the standard, causing a great safety hazard. The gap between the waterproof rubber ring and the pipeline airtightness is not enough
