Description

[Detailed description of the invention] The present invention relates to a roofing base material that does not require marking and fully demonstrates the marking function. The present invention provides a removably integrated roof base material.

Hereinafter, the present invention will be explained based on the drawings.

The figure is a sectional view of a roof base material according to an embodiment of the present invention, and in the figure, 1 is a base material.

As this base material 1, asphalt roofing, vinyl chloride resin, polyethylene resin, etc. are used, and its main function is waterproofing.

However, on a part or all of the surface of the base material 1 of the lever, threads 2 are linearly arranged and overlapped.

Here, as the thread 2, a material such as synthetic resin or paper is used, and for integration, an appropriate method such as fusion or adhesion is selected in consideration of the materials of the base material 1 and the thread 2. .

In this case, the thread 2 is made by laminating, for example, a sheet made of synthetic resin or the like on the surface of the base material 1, and then making high-density cuts in a straight line only on this sheet, and stacking each sheet independently. It's okay.

Further, the thread 2 must have a peeling strength that is weaker than the tensile strength of the thread, regardless of which method is used, such as fusing or adhesion.

In this respect, point fusion or point adhesion is preferable, and if the yarn 2 is made of paper whose tensile strength decreases due to water absorption, it is not preferable because peeling from the base material 1 will not be possible if the yarn is applied in the rain.

Further, when peeling, the thread 2 is removed, and the original linear trace of the thread 2 has a score effect and is given distinguishing power.

In this case, the discrimination ability is improved by the difference in the base color of the thread 2, such as the coloring of the thread 2 and the coloring of the adhesive used for adhesion, or the coloring of the base material 1 to which the thread is fused. It is preferable to use a base material 2 to be coated or a thread 2 colored differently from the base color of adhesive or the like.

In the roof base material constructed as described above, by peeling the desired thread 2 from the base material 1, a linear mark having distinguishing power is formed, so marking is not necessary.

Furthermore, as a result of the overlapping of the threads 2, a rough, uneven surface is formed on the upper surface, which prevents it from slipping off even when embanking, allowing for stable placement, and also improving the possibility of feet slipping during construction. It also produces a derivative effect.
