Abstract

The utility model discloses a waved waterproof roll which is in a waved shape. A lap joint structure is arranged on edges of two opposite sides of the waterproof roll, and the lap joint structure is composed of a first lap joint portion and a second lap joint portion which are matched with each other. The first lap joint portion is arranged on the edge of one side of the waterproof roll, and the second lap joint portion is arranged on the edge of the other side of the waterproof roll. The first lap joint portion is a step which is lower than the upper surface of the waterproof roll, and the second lap joint portion is a step lower than the lower surface of the waterproof roll. The waved waterproof roll has the advantages that the structure is simple, the waved waterproof roll is stretchable and can be conveniently laid on a round or tapered waterproof base surface, and the occurrence of the condition that the roll is cracked in the using process is reduced; the lap joint of the roll can be firm and natural, and the roll is integrated; and the waved waterproof roll can play a better role in water resistance and seal and is attractive in appearance, and a lap joint mark can not be seen easily.

Description

Corrugated waterproof roll

Technical field

The utility model relates to building material technical field, is specifically related to waterproof roll.

Background technology

At present, waterproof roll mostly is planar sheet, is laid on top of building or bottom surface in the work progress, anti-sealing and wet gas enter, because waterproof roll is sheet, is well suited for being laid on the common plane building basal plane, the waterproof basal plane that runs into circular and taper is then laid difficulty.

In order to solve above-mentioned deficiency of the prior art, the utility model proposes a kind of new solution.

The utility model content

The purpose of this utility model provides a kind of corrugated waterproof roll, can be laid on easily the waterproof roll on circle and the taper waterproof basal plane, and the junction can be more firmly between coiled material, the overlap joint of nature is integrated.

For reaching the foregoing invention purpose, the technical scheme that the utility model adopts is: a kind of corrugated waterproof roll is provided, has it is characterized in that: waterproof roll is corrugated, and the edge of the relative both sides of waterproof roll is provided with bridging arrangement.

Described bridging arrangement is comprised of the first clinch and the second clinch that mutually coincide, and the first clinch is arranged at a lateral edges of waterproof roll, and the second clinch is arranged at waterproof roll opposite side edge.

Described the first clinch is the step that is lower than the waterproof roll upper surface; Described the second clinch is the step that is lower than the waterproof roll soffit.

The shoulder height of described the first clinch is 1/2nd of waterproof roll thickness; The shoulder height of described the second clinch is 1/2nd of waterproof roll thickness.

In sum, corrugated waterproof roll provided by the utility model has following advantage:

1, simple in structure, retractility is arranged, can be laid on easily on circle, the taper waterproof basal plane, and can reduce the in use generation of web break situation;

2, the junction can be more firmly between coiled material, the overlap joint of nature is integrated.Can play better waterproof sealing function, again can better appearance, be difficult for finding out the overlap joint vestige.

Description of drawings

Fig. 1 is structural representation of the present utility model;

Fig. 2 is the partial enlarged drawing of A part among Fig. 1.

Wherein, 1, waterproof roll; 2, the first clinch; 3, the second clinch.

The specific embodiment

Below in conjunction with accompanying drawing the specific embodiment of the present utility model is described in detail.

-as depicted in figs. 1 and 2, and this waterproof roll 1, integral body is corrugated, the edge of the relative both sides of waterproof roll 1 is provided with bridging arrangement.

Described bridging arrangement is comprised of the first clinch 2 and the second clinch 3 that mutually coincide, and the first clinch 2 is arranged at a lateral edges of waterproof roll 1, and the second clinch 3 is arranged at waterproof roll 1 opposite side edge.

Described the first clinch 2 is for being lower than the step of waterproof roll 1 upper surface; Described the second clinch 3 is for being lower than the step of waterproof roll 1 soffit.

The shoulder height of described the first clinch 2 is 1/2nd of waterproof roll 1 thickness; The shoulder height of described the second clinch 3 is 1/2nd of waterproof roll 1 thickness.

In order to connect reliably between the first clinch 2 and the second clinch 3, suggestion bonds together therebetween mutually.

Although by reference to the accompanying drawings the specific embodiment of the present utility model is described in detail, should not be construed as the restriction to the protection domain of this patent.In the described scope of claims, the various modifications that those skilled in the art can make without creative work and distortion still belong to the protection domain of this patent.
