Abstract

The utility model relates to a sealing cap for building layer through pipes, which is a cylindric ring. Openings which have different diameters are arranged on the two ends of the cylindric ring, the diameter of the upper part of a cylinder is small, the diameter of the lower part is big, the middle part forms a horn shape, and the outer margins of the openings of the cylindric ring are provided with clamping bolt holes. A sealing cap can be tightly fixed and covered on a bushing with a through pipe, the problems of water leakage, cross talk, dust fall, etc. between building layers can be eliminated. The utility model also has the characteristics of simple structure, easy production, low cost, convenient use, etc.

Description

A kind of floor poling sealing cap

The utility model relates to a kind of building product, particularly gives, the drainage fitting technical field.

In building operations, floor gap is covered with a large amount of pipelines, and heat expansion is cool to contract to the damage problem of floor in order to solve, and stipulates that in a local regulation 91SB1 job practices pipeline will add a sleeve pipe at interlayer when passing floor, and pipeline passes from sleeve pipe.But this job practices can only solve the problem of expanding with heat and contract with cold of pipeline, has but produced drawbacks such as the downward flowing water of suitable sleeve pipe, cross-talk, and dust fall thus simultaneously.For this reason, when the relevant construction of country was defined in thicker pipeline poling again, packing between sleeve pipe and pipeline was sealed with capping then, and this technology is time-consuming, take a lot of work, make troubles to construction, and concerning thinner pipeline, also inconvenience is adopted simultaneously.

The utility model purpose be to provide a kind of solve between the upper and lower layer leak, the poling sealing cap of problems such as cross-talk, dust fall.

The purpose of this utility model is achieved in that

A kind of floor poling sealing cap, its special feature are that it is the opening cylinder ring that a two ends diameter does not wait, and the cylinder upper diameter is less, and lower diameter is bigger, and it is horn-like that the middle part is, and opening two outer rims of described cylinder ring have clamp bolt hole.

Above-mentioned poling sealing cap, the opening two outer rim medial surfaces of described cylinder ring are intermeshing convex concave.

Above-mentioned floor poling sealing cap, described cylinder ring also can be made separation type, is made up of two semi-circular cylinder rings, in each semi-circular cylinder ring both sides outer rim is arranged all, and uniform bolt hole.

The sealing cap that adopts said structure to make, in use, sealing cap diameter small upper and poling are closely fixing, and the bigger bottom shoe of diameter is placed on the sleeve pipe, therefore water droplet, noise, dust etc. all can not arrive the gap location between poling and the sleeve pipe, have stopped effectively from the upper strata to phenomenons such as lower floor suitable cover tube leakage, cross-talk and dust falls.Advantages such as this sealing cap also has simple structure, makes easily, and cost is low, and is easy to use.

Fig. 1 is the utility model A-A sectional view;

Fig. 2 is the utility model vertical view;

Fig. 3 is the utility model user mode figure.

Concrete structure of the present utility model is such: sealing cap is a cylindrical object in general, and top is the less cylinder of a diameter 1, and the bottom is the bigger cylinder of a diameter 2, and upper and lower cylinder becomes horn-like connection 3.Side at this cylinder has a top-down entire body opening, respectively there is a

flange

4,5 opening outer rim both sides, clamp bolt hole 6 is arranged on flange, convex projection 7 is from top to bottom arranged on the flange 4, the groove 8 that matches with projection 7 is arranged on the flange 5, when using clamping, projection 7 is meshed with groove 8.

Represent among user mode Fig. 3, floor perforation place fixed sleeving 9, poling 10 passes from sleeve pipe 9, and the slit is arranged between them.During use, the opening part of sealing cap is separated to both sides, be enclosed within on the poling 10, top cylinder 1 diameter should match with poling 10, and bottom cylinder 2 should be carried out and be placed on the sleeve pipe 9, and projection 7 clamps with groove 8 engagements and with bolt.

This sealing cap adopts plastics, and rubber or other elastomeric material are manufactured, so that can be from opening part separately and fastening with poling.

This sealing cap should be made the product of plurality of specifications according to the different-diameter of poling, and top cylinder 1 can be closely fixing with poling during use, do not stay the slit, and bottom and sleeve pipe shoe cover completely close.The poling bigger to diameter, sealing cap also can be made two bodies, is made up of two semi-circular cylinder rings, in each semi-circular cylinder ring both sides flange is arranged all, and uniform bolt hole, uses bolt.

Claims

1. a floor poling sealing cap is characterized in that, it is the opening cylinder ring that a two ends diameter does not wait, and the cylinder upper diameter is less, and lower diameter is bigger, and it is horn-like that the middle part is, and opening two outer rims of described cylinder ring have clamp bolt hole.

2. according to the described sealing cap of claim 1, it is characterized in that the opening two outer rim medial surfaces of described cylinder ring are intermeshing convex concave.

3. sealing cap according to claim 2 is characterized in that described cylinder ring also can be made separation type, is made up of two semi-circular cylinder rings, in each semi-circular cylinder ring both sides outer rim is arranged all, and uniform bolt hole.
