Technical Field

The invention relates to the technical field of building drainage, in particular to a multifunctional telescopic embedded part.

Background

Modern buildings are especially high-rise buildings, and the design and installation of water supply and drainage pipes are indispensable work, so that the building needs to embed a water pipe sleeve or a joint when a floor layer is poured in the construction process, and the method adopted most at present is as follows: when pouring, pre-buried a rigid sleeve or plastic sleeve earlier, treat floor layer thoroughly dry back and connect upper and lower water supply and drainage pipe, can have the gap between connection back water supply and drainage pipe outer wall and the sleeve, present mostly water cement mortar once more in the contact gap to anticreep prevention of seepage, it is big to reach the density degree of difficulty when adopting this type of secondary to pour, the operation requirement is high, and cement mortar often combines not inseparably enough, can appear the water leakage phenomenon often, and the maintenance is stranded. Waterproof ointment or glue is also adopted for joint filling treatment, but in practice, the sealing of the gap is difficult to meet the requirement, and phenomena of pipe loosening, water leakage and the like often occur. And when the water pipe in actual use is inconsistent with the originally designed water pipe, the water pipe cannot be installed.

Disclosure of Invention

The invention aims to overcome the defects of the prior art and provide the embedded part which has good sealing effect and no water leakage and can stretch and change the pipe diameter.

In order to achieve the purpose, the technical scheme provided by the invention is as follows: a multifunctional telescopic embedded part comprises a base and a sleeve, wherein a floor sealing water stop ring is arranged on the outer side wall of the base, and a pipe inserting groove is formed in the lower end of the base; the lower end of the sleeve is movably assembled at the upper end of the base in an inserting, clamping or threaded connection mode; the upper end of the sleeve is provided with a fastening nut, and a sealing groove is arranged in the fastening nut.

The lower end of the base is provided with a lower fastening piece.

The base and the inserting part of the sleeve are in a matched step shape.

The inner diameter of the base intubation part is consistent with that of the sleeve intubation part.

The inner diameter of the base intubation part is larger than that of the sleeve intubation part.

The inner diameter of the base intubation part is smaller than that of the sleeve intubation part.

The outer side wall of the base is provided with a reinforcing rib, and the reinforcing rib is connected with the bottom of the base to form a supporting structure of the embedded part.

The inner diameter of the intubation part of the lower fastener is consistent with that of the intubation part of the base.

The inner diameter of the intubation part of the lower fastener is larger than that of the intubation part of the base.

The inner diameter of the intubation part of the lower fastener is smaller than that of the intubation part of the base.

The invention has the advantages that: firstly, the method comprises the following steps: the base and the sleeve are movably connected, and the device can be suitable for floors of any height. Secondly, the method comprises the following steps: the stiffening rib of base lateral wall can not only prevent to warp when the drain pipe is pegged graft, can make the base better moreover with floor layer cement between combine. Thirdly, the method comprises the following steps: after the floor sealing water stop ring is adopted, secondary grouting is not needed, and time and labor are saved. Fourthly: the embedded part of the scheme can be suitable for connection between any pipe diameters. Fifth, the method comprises the following steps: after the embedded connection and the spiral connection are adopted, the maintenance is convenient, and only corresponding sleeves or fasteners need to be replaced.
