Abstract

The invention provides an anti-leakage joint, which is used with the protruding part of rain water drainage pipe on roof. The invention is characterized in that the middle part of the joint has an umbrella-shaped structure. The invention effectively avoids leakage of rain water from the external wall of the drainage pipe, and has good anti-leakage effect.

Description

Roofing upper and lower conduit road leans out the leakproof joint of part

Technical field

The present invention relates to a kind of joint of sewer pipe, particularly a kind of roofing upper and lower conduit road leans out the leakproof joint of part.

Background technology

All kinds of sewers generally all are installed in the middle of all kinds of buildings, for the air pressure inside and outside the equalizing main, simultaneously also in order to discharge the fuel gas such as biogas that produce in the sewer pipe, these pipeline tops all will be passed the roof and have air-vent, after roof concreting sclerosis, be easy to around pipeline, form small gap, also just formed along the passage of sewer outer tube wall seepage, the antiseep gap filler that many kinds are arranged now, sealing effectiveness is better time spent when just beginning to drop into, the variation of four seasons changes in temperature also can produce the seepage phenomenon because the coefficient of expansion of pipeline and cement is different but As time goes on.

Summary of the invention

Purpose of the present invention is exactly in order to overcome the defective in the middle of the above-mentioned prior art, for the sewer pipe that leans out from the roof provides a kind of leakproof joint simple and reasonable, easy to install, make it can solve rainwater along the pipeline outer wall leakage problems, do not influence simultaneously the outward appearance of building again, reduce maintenance cost in this respect.

Content of the present invention realizes by following technical proposals: a kind of roofing upper and lower conduit road leans out the leakproof joint of part, comprises the cylindrical pipe joint of one up and down, is positioned at the umbrella rain-proof structure in centre position; The described pipe joint of one up and down, its external diameter all is equal to or slightly less than the internal diameter of existing sewer pipe, on this joint outer wall tactic circular protrusion is arranged, coat after the bonding adhesive that is used for fixing can with the existing sewer butt joint at two ends up and down, and make the umbrella-shaped structure that is positioned at mid portion cover on the top of the waterproof cement around the sewer.

The invention has the advantages that it has solved the sewer that passes the roof problem along sidewall seepage rainwater, rainproof effective, easy for installation, do not influence the outward appearance of building simultaneously again, reduce maintenance cost in this respect.

The specific embodiment

Embodiment 1

Fig. 1, Fig. 2, Fig. 3 and Fig. 4 are respectively the installation design sketch of embodiments of the invention 1, partial enlarged drawing, sectional view and member decomposing schematic representation, the connector 2 of leakproof joint top and the bottom and 3 outer wall all have circular protrusion among the figure, the middle umbrella-shaped structure 1 that connects, enclose antiseep cement 7 around one of sewer below being used to cover, last lower union joint 2, circular protrusion on 3 and umbrella-shaped structure 1 are unique textures of the present invention, umbrella-shaped structure designs in order to prevent the intersection that rainwater drops on antiseep cement and the following sewer of this joint, the circular protrusion that has on the last lower union joint so that when connecting up and down the both sides sewer spreading glue to increase adhesive power.

The using method of leakproof joint of the present invention sees also Fig. 4, and step is as follows:

Sewer pipe upper limb level of antiseep cement around it of building on part 9 and the tile 8 on the roof is sawed-off with leaning out;

With coated with adhesive on the circular protrusion outside the lower union joint of this leakproof joint, and insert in the following sewer 6 of rapid this joint that produces of previous step bonding consolidation;

Coated with adhesive on the circular protrusion outside the upper binding head of this leakproof joint, and cover glues one section above sewer 5 of this joint that has air-vent 4 thereon;

End-results has good leak preventing effect as shown in Figure 1, 2.

Embodiment 2

We can further simplify this leakproof joint such as Fig. 5 in the application of reality, and Fig. 6 is the longitudinal sectional view of this structure,

In this structure, the air-vent in the foregoing description 14, sewer 5 more than this joint and upper binding head 2 and umbrella-shaped structure 1 lower union joint 3 are combined together when the processing and manufacturing, having only a bonding portion when bonding with the sewer below this joint like this, make install, safeguard convenient.

Above leakproof joint has been arranged, after the construction of part 9 is built on the roof, the bonding work that we need only carry out between tile 8 and the antiseep cement 7 on it gets final product, because the coefficient of expansion of cement and tile is more approaching, so generally the seepage phenomenon can not occur between tile 8 and the dish seepage cement 7, we can consider structure that antiseep cement 7 tiles 8 are made of one in addition, and the antiseep effect will be more outstanding like this.

The material of this Matheson and Dresser joint can be selected for use and identical PPR, the UPVC etc. of sewer commonly used now, also can select the material of corrosion-resistant weather resistances such as stainless steel, aluminium alloys, pottery for use, optimal way of the present invention is to adopt this leakproof joint of glazed ceramic processing and manufacturing.

The present invention is not limited only to the illustrated ridged roof that opens in addition, equally also is applicable to the plane roof.Below only be several preferred embodiment of the present invention,, all should belong to the protection domain of patent of the present invention so utilize inventive concept of the present invention to carry out the structural change of unsubstantiality such as.
