り込む不都合もあつた。 Generally, to form a waterproof base for mortar wall bases, dry exterior siding materials, roof bases, etc., two people work to lay a roll-shaped waterproof sheet 1 m wide, 21 m long, and 17 kg in weight on top of the roof board. The waterproof sheet was unwound by a worker to cover the horizontal base at the lower end, cut the waterproof sheet at this position, and then returned to its original position and laid the waterproof sheet to cover the higher position. It was necessary to perform several operations over the required width and height, such as fixing the lower end of the sheet overlapping the upper end of the waterproof sheet while unwinding the sheet, and then laying the waterproof sheet. Therefore, two skilled workers are required for construction, and they must move horizontally while holding heavy rolls on the wall, which is extremely dangerous, difficult work, and inefficient. It was hot. Construction work was almost impossible, especially on windy days. In addition, the overlapping portions of the waterproof sheet had double overlap, which caused the inconvenience that water would flow around to the base material due to capillary action.

Moreover, the present invention provides a method for forming a waterproof base having a triple-polymer structure in which the striated protrusions reliably block rainwater from leaking from the polymerized portion to the base due to capillary action or the like.

Ｗは２〜５mm位である。 The waterproof base forming method according to the present invention will be explained in detail below using the drawings. FIG. 1 is a perspective view showing an example of a unit waterproof sheet used in the present invention. 1 is a unit waterproof sheet with a rectangular outer shape, for example, a square or rectangular shape, and linear protrusions 2 are arranged on at least one side at an appropriate pitch P. has been done. Also, a pair of right-angled corners on the diagonal line are cut into an isosceles triangular shape having the inclined side 3 of the same length as the base. In other words, the part indicated by the two-dot chain line is cut out from the waterproof sheet material made of asphalt felt, asphalt roofing, synthetic resin sheet, etc. This is because four unit waterproof sheets are polymerized during construction. However, the polymerization part is 3
This is to have a multi-layered structure, to reduce the thickness of the overlapped portion, and to effectively function to improve waterproofness. In addition, the size of the unit waterproof sheet 1 is approximately 1 meter square, making it easy to carry and easy to install even by one person. The portion is cut into a triangular shape to reduce the thickness of the overlapping portion that occurs. In addition,
Isosceles triangle shape etc. is not limited to isosceles triangles only, but both opposing triangles are congruent shapes,
This also includes cases where various triangles are formed symmetrically. Further, the linear protrusion 2 has a height h of about 1 to 5 mm, and a width W of about 2 to 5 mm.

ように敷設する。 Therefore, it is assumed that a waterproof base material is formed on a base material 4 such as a lath board as shown in FIG. 2a. First, as shown in FIG. 2A, the unit waterproof sheet 1 is fixed with staples 5 so that its right-angled corner is located at the lower right corner of the base material 4. Next, as shown in Fig. 2b, the unit waterproof sheet 1-1,
1-2 is laid on the upper edge or left side edge of the previous unit waterproof sheet 1 so that the inclined sides 3 are located in the same direction, and fixed with staples 5. That is, the unit waterproof sheets 1-1 or 1-2 are overlapped with each other at a width W0 that ensures that the inclined sides 3 of the unit waterproof sheets 1-1 or 1-2 are present on the right-angled corners of the unit waterproof sheets 1,
In addition, the unit waterproof sheets 1-1 and 1-2 are laid immediately so that the inclined sides 3 of the unit waterproof sheets 1-1 and 1-2 are butted against each other at the right-angled corners. Next, as shown in Fig. 2c, unit waterproof sheet 1-3 covers the left edge and upper edge of unit waterproof sheets 1-1 and 1-2, and butts them onto the right-angled corner of unit waterproof sheet 1. One of the right-angled corners of the unit waterproof sheet 1-3 is laminated on the laminated overlapping portion as shown. As a result, the overlapping portion of the four unit waterproof sheets 1 has a three-layer waterproof structure. Therefore, in order to form the required waterproof base, such operations may be repeated in sequence. In addition, during construction, the unit waterproof sheet 1 is laid so that the linear protrusions 2 are positioned in the vertical direction.

る。 As mentioned above, the method for forming a waterproof base according to the present invention allows one person to easily perform work on vertical walls, high and dangerous roofs, etc. without requiring any technical skill.
Moreover, there is no risk of being blown away by the wind, and since the striated protrusions are present in the lateral overlapping parts, it has a reliable waterproofing function that improves the waterproofness of the overlapping parts and can form a waterproof base with high efficiency. Also,
Regardless of whether the substrate has a small area or a large area, it is advantageous that it is very easy to tighten the edges because it is only necessary to change the overlapping width. Furthermore, the cutting width of the inclined side of the unit waterproof sheet can be effectively used as a guideline when superimposing the unit waterproof sheet.
