Description

Mounting structure of steel lining plastic drainage pipe fitting

Technical Field

The utility model relates to a water drainage pipe fitting, specific mounting structure of water drainage pipe fitting is moulded to steel lining that says so.

Background

At present, PVC drainage pipelines are mostly adopted for building drainage pipelines to be laid along the corners of kitchen and toilet walls in an exposed mode, so that the PVC drainage pipelines occupy indoor space and are not beneficial to the installation and arrangement of kitchen and toilet equipment. The PVC drain pipe is limited by the function of the drain pipe for draining, and if the PVC drain pipe is laid in a concealed mode, the PVC drain pipe is required to be installed in a concrete beam, and the concrete beam poured as concrete has a large difference between a thermal expansion system and the PVC drain pipe, so that serious problems such as the rupture of the drain pipe and the like are easily caused.

On the other hand, for the toilet with the backfill layer, the open drain floor drain hole is formed in the surface of the decorative tile surface layer on the ground, and only water above the ground can be collected.

Disclosure of Invention

The utility model aims at solving the technical problem, provide a water drainage pipe's mounting structure is moulded to steel lining that the structure is very simple, the body is difficult for breaking, long service life, can realize that the concealed installation lays, effectively avoids the backfill layer seepage water to overflow.

The technical scheme includes that the PVC drainage pipe is embedded in a concrete beam, socket joint connecting ports are formed in the upper end and the lower end of the PVC drainage pipe, a steel shell is integrally sleeved outside the PVC drainage pipe and the socket joint connecting ports at the two ends, and no gap exists between the steel shell and the PVC drainage pipe.

And the middle section of the PVC drain pipe is connected with a drain branch pipe.

The lower section of the PVC drain pipe is connected with a hidden drainage floor drain opening through a steel hidden drainage pipe, and the hidden drainage floor drain opening is flush with the upper surface of the concrete slab below the backfill layer.

The PVC drainage pipe is characterized in that a socket joint connecting port of the PVC drainage pipe is connected with a drainage vertical pipe, a foaming film isolation layer is wrapped outside the drainage vertical pipe, and a masonry is arranged outside the foaming film isolation layer.

Has the advantages that:

1) the utility model discloses an at PVC drain pipe external suit steel casing, the steel casing can effectively protect the PVC drain pipe on the one hand, and the coefficient of expansion of on the other hand steel casing is unanimous basically with the concrete to satisfy the drain pipe and bury underground and do not produce the requirement that warp the damage in reinforced concrete, improve the life of body by a wide margin.

2) The steel concealed drain pipe penetrates through the concrete slab to be connected with the concealed drain hole, and the concealed drain hole is flush with the upper surface of the concrete slab below the backfill layer, so that the water leakage in the backfill layer can be completely and effectively collected, and the influence of long-term water accumulation in the backfill layer on the concrete slab below the backfill layer is avoided.

3) The utility model discloses simple structure, can realize that the dark dress of drain pipe lays, the body is difficult for breaking, long service life, effectively avoid the backfill layer infiltration to overflow.

Drawings

Fig. 1 is a schematic structural diagram of embodiment 1 of the present invention.

Fig. 2 is a schematic structural diagram of embodiment 2 of the present invention.

Fig. 3 is a schematic structural diagram of embodiment 3 of the present invention.

The concrete floor comprises, by weight, 1-a steel shell, 2-a PVC drain pipe, 3-a socket joint connector, 4-a steel concealed drain pipe, 5-a concealed drain floor drain, 6-a foamed film isolation layer, 7-a decorative tile surface layer, 8-a mortar layer, 9-a concrete beam, 10-a backfill layer, 11-a concrete slab, 12-a drainage vertical pipe, 13-a drainage branch pipe and 14-masonry.

Detailed Description

The invention will be further explained with reference to the drawings:

example 1: the PVC water discharge pipe is characterized in that socket joint connecting ports 3 are formed in the upper end and the lower end of the PVC water discharge pipe 2, the steel shell 1 is integrally sleeved outside the PVC water discharge pipe 2 and the socket joint connecting ports 3 at the two ends, and no gap exists between the steel shell 1 and the PVC water discharge pipe 2. Specifically, the steel shell 1 can be prepared and formed, then the PVC drain pipe 2 and the socket joint 3 are integrally injection-molded into the steel shell, and the formed PVC drain pipe 2 and the steel shell 1 have no gap.

When a concrete beam 9 is poured, the PVC drain pipe 2 and the steel shell 1 are embedded into the concrete beam 9 together, socket joint connecting ports 3 at two ends are reserved for connecting upper and lower drainage vertical pipes 12, the drainage vertical pipes 12 are wrapped with a foaming film isolation layer 6, and masonry is arranged outside the foaming film isolation layer 6.

Example 2

The difference from example 1 is: the middle section of the PVC drain pipe 2 is also connected with a drain branch pipe 13 which is used for connecting various water using devices on the ground, such as a drain pipe of a toilet or a hand washing sink.

Example 3

The difference from example 2 is:

the lower section of the PVC drain pipe 2 is connected with a hidden drainage floor drain opening 5 through a steel hidden drainage pipe 4, and the hidden drainage floor drain opening 5 is flush with the upper surface of a concrete slab 11 below the backfill layer 10. Because the steel concealed conduit 4 is embedded in the concrete slab 11, the steel is directly adopted, thereby avoiding deformation and damage. When the ground surface leaks, the seepage water flows into the backfill layer 10 through the decorative ceramic tile surface layer 7 and the mortar layer 8, continues to go down and finally is collected by the blind drain hole 5 and is collected by the steel blind drain pipe 4 to be gathered into the PVC drain pipe 2 for discharge, thereby effectively dredging the seepage water in the backfill layer and solving the problem of overflowing discharge in the same-layer drainage mode for a long time.
