Abstract

The utility model relates to a building pipe, in particular to a wall bushing. The wall bushing comprises a bushing body, wherein the upper end and the lower end of the bushing body are respectively provided with an annular protruding edge, a plurality of annular protruding edges are arranged between the upper end and the lower end of the bushing body, and the bushing body is cut along the center line to form two half bodies which are spliced. The annular protruding edges can prevent water from seeping downwards along the outer surface of the wall bushing and can block seepage water. Preferably, the wall bushing is made of engineering plastics, such as flame retardant PVC and PP-R. The wall bushing is especially suitable for being used in toilets, kitchens, rooms and other places where through-wall pipes are arranged. The wall bushing has the advantages of being simple in structure, good in water resistance and strong in practicability, the seepage problem in toilets is better solved, and the wall bushing can be conveniently popularized and used in constructional engineering.

Description

Wall bushing

Technical field

The utility model relates to a kind of building pipe, i.e. wall bushing.

Background technique

In the prior art, interting up and down between the building floor has plastic tap water pipe, gas pipe line etc., should leave the gap between running water pipe and the perforation, to adapt to expanding with heat and contract with cold of plastic tap water pipe.Staying the gapped practice in the reality is to wrap the galvanized sheet iron cylinder and carry out gluing at seam crossing between perforation and plastic tap water pipe.Even but made water-proofing treating for the running water pipe that interted in the toilet at the ground perforation place, also can cause seepage herein because of the infiltration of galvanized sheet iron cylinder seam crossing.So the seepage between toilet sewer, running water pipe and the perforation is main breakthrough, there is not so far the good method that solves.

The model utility content

The purpose of this utility model is to provide a kind of anti-leakage effective wall bushing for above-mentioned deficiency.

Technical solution of the present utility model is: wall bushing comprises body, has together or one above circular fin along circumference at the body outer round surface.The effect of circular fin is to prevent that sealing along oozing under the wall bushing outer surface, stops infiltration.The preferred engineering plastics material of wall bushing is such as fire-retardant PVC, PP-R etc.Wall bushing is specially adapted to toilet, kitchen etc. the wall-passing pipe place.Also can be used for other pipelines such as gas pipe line, heating pipe, circuit place through walls use.

There is circular fin preferred body upper end, lower end (so that wall bushing is not subjected to the restriction of above-below direction when installing and using, installation, easy to use), the multiple tracks circular fin is arranged between the body upper and lower end, also so that slush is combined closelyr with wall bushing, anti-seepage effect is better when blocking water.

Body is the halved body along the docking of center line incision, at docking plastic emitting seal mouth, more is applicable to the water-impervious transformation (because running water pipe is installed, the halved body structure is convenient to snapping) to existing house running water pipe during use.

Body halved body interface is the convex-concave plug in structure, and snapping face place is in conjunction with firm, and gluing sealing is tightr.

The utility model has the advantages that: simple in structure, block-water effect is good, and is practical, solved preferably toilet upper and lower conduit, kitchen gas pipe seepage difficult point, is convenient to apply in the construction engineering.

Below in conjunction with accompanying drawing mode of execution of the present utility model is described in further detail.

Description of drawings

Fig. 1 is the utility model structure diagram.

Fig. 2 is Fig. 1 plan structure sketch.

Fig. 3 is structure diagram in the utility model use state.

Embodiment

Referring to Fig. 1, wall bushing comprises body 1, and body 1 outer round surface has six road circular fin 2(width 8mm along circumference, height 2-3mm etc.).

There is circular fin 2 body 1 upper end, lower end, and four road circular fins 2 are arranged between the body upper and lower end.

Referring to Fig. 2, body 1 is the halved body along the docking of center line incision.The halved body interface is to be triangle among the convex-concave plug in structure 3(figure, but is not limited to this).

Wall bushing length is greater than slab thickness (such as 220mm), and the wall bushing diameter can have plurality of specifications according to wall-passing pipe diameter difference, and seriation (such as ￠ 70mm, ￠ 110mm, ￠ 130mm etc. are not limited to this).

Referring to Fig. 3, wall bushing in the use state is running water pipe 4, body 1, floor 5 from the inside to the outside.

Claims (2)

1. a wall bushing comprises body (1), it is characterized in that there is circular fin (2) body (1) upper end, lower end, have multiple tracks circular fin (2) between body (1) upper and lower end; Body (1) is the halved body along the docking of center line incision.

2. according to wall bushing claimed in claim 1, it is characterized in that body (1) halved body interface is convex-concave plug in structure (3).
