Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for attaching a waterproofing sheet to a wall base.

[0002]

2. Description of the Related Art Conventionally, when fixing an outer wall material such as a wall plate to the surface of a pillar or a stud, first, a waterproofing sheet for the wall is attached on the envelope surface of the pillar or the stud, and then the outer wall material is appropriately attached to the surface. It is applied and fixed by means. However, if the outside of the wall surface to be constructed is a narrow land with a very small gap with the adjacent land, it is not possible to carry in the wall material from the outdoor side. It is impossible to carry out and it is impossible to fix the outer wall material.

Therefore, conventionally, in such a case as shown in FIG.
As shown in Fig. 3, a waterproof sheet B is attached corresponding to the position where one outer wall material A is attached, and then the outer wall material A is carried out from the indoor side and fixed to the enveloping surface of the pillars and studs C.
The outer wall material A is repeatedly attached by using the same as above, or as shown in FIG. 6, a waterproof sheet B having a double or triple width of the outer wall material A is attached in the same manner as described above, and the waterproof sheet B is attached to the waterproof sheet B. After providing a cut F through which the fitting E is exposed, the outer wall material A is fixed by the fitting E through the cut F.

[0004]

However, in the case of the means shown in FIG. 5, it is necessary to prepare the waterproof sheet B corresponding to the width of the outer wall material A. Normally, the width of the waterproof sheet B is the width of the outer wall material A. Since it is double to triple the width, cutting a long waterproof sheet at the construction site is a very troublesome work, and there is a drawback that construction becomes difficult. Further, in the case of this construction method, it is necessary to alternately carry out the work of sticking the wall underlayer waterproof sheet B and the work of sticking the outer wall material A, which is a repetitive work, and there is a drawback that efficiency is poor.

In the case of the fixing means shown in FIG. 6, it is possible to save the labor of cutting the waterproof sheet B, but it is necessary to provide a cut F for the fixing metal fitting E in the waterproof sheet B, and the repair work after the cut F is required. There was a drawback that it became indispensable and the work was troublesome. Further, when the outer wall material A is carried out from the space between the pillars and the studs C, an accident such as catching and breaking the waterproof sheet B is likely to occur, and there is a drawback that the work is very difficult to perform.

[0006]

SUMMARY OF THE INVENTION In view of the above problems, the present invention makes it possible to apply a waterproof sheet and an outer wall material efficiently and waterproofly in a narrow area with a small gap between adjacent areas. The purpose of the present invention is to provide a method for attaching a wall-base waterproof sheet.

[0007]

That is, the method for attaching a wall-base waterproof sheet according to the present invention is a strip having a width capable of covering the pillar 1 and the stud 1A and substantially equal to the width between the pillar 1 and the stud 1A. In the vertically arranged state, the wall underwater waterproof sheet 4 of No. 1 is extended vertically to the outer wall member 2 mounting surface 3 of the pillar 1 and the stud 1A, and both ends in the width direction are extended, and the intermediate strips thereof are attached, and the extended ends 4A and 4A are The pillar 1 and the stud 1A are wound around the outer circumference and temporarily fixed, then the outer wall material 2 is fixed to the pillar 1 and the stud 1A, and then the temporarily fixed wall base waterproof sheet 4 is developed and placed along the back surface of the outer wall material 2. At the same time, the extended ends 4A and 4A are overlapped and fixed on the back surface of the outer wall member 2.

[0008]

In the present invention, the underlayer waterproof sheet 4 is a strip having a width capable of covering the gap between the pillar 1 and the stud 1A, and the intermediate band is vertically arranged on the outer wall material mounting surface 3 of the pillar 1 and the stud 1A. It can be pasted. Then, since the wall base waterproof sheet 4 is wound around the outer periphery of the pillar 1 and the stud 1A and temporarily fixed, the space of the pillar 1 and the stud 1A can be used, and the wall base waterproof sheet 4 is not damaged from the space. The material 2 can be carried out. Then, after fixing the outer wall material 2 to the surfaces of the pillar 1 and the stud 1A, if the extended ends 4A and 4A of the wall base waterproof sheet 4 are developed along the back surface of the outer wall material 2,
If the underlayer waterproof sheets 4 extending from the adjacent pillars 1 and studs 1A overlap each other on the back surface of the outer wall material 2 and are stuck and fixed in this state, the back surface of the outer wall material 2 is completely waterproofed.

[0009]

Embodiments of the present invention will be described below. 1 to 4 are plan views showing an implementation state of the method of the present invention.

[Example 1] As shown in FIG. 1, a wall-base waterproof sheet 4 having a width of 1 m, which is generally used conventionally, such as asphalt-impregnated felt and breathable waterproof sheet, is vertically arranged.
The central portion in the width direction is attached and fixed to the outer wall member 2 mounting surface 3 of the pillar 1 and the stud 1A using a double-sided adhesive tape or staple 6, and the extending ends 4A and 4A on both sides are the pillar 1 and the stud 1.
It was wrapped around the outer circumference of A and temporarily fixed with adhesive tape 5. The distance between the pillar 1 and the stud 1A was 450 mm. Further, a slit for inserting a fitting (not shown) for attaching the outer wall member 2 was provided in a key portion of the wall base waterproof sheet 4, and the head of the fitting was passed through this slit, and the base was fixed to the side of the pillar 1 and the stud 1A.

Next, as shown in FIG. 2, a pillar 1 and a stud 1A.
The outer wall material 2 is carried out from between the spaces using the space opened from the indoor side, fixed to the surface of the pillar 1 and the stud 1A, and the outer wall up to the height corresponding to the width of the wall base waterproof sheet 4 (paper spine direction in FIG. 2). Material 2 was attached and fixed. Then, the temporarily fixed wall base waterproof sheet 4 is unwound, and the extending ends 4A and 4A are spread along the back surface of the outer wall material 2 and overlapped as shown by the dotted arrows in FIG. 3, and the double-faced tape 5A is appropriately used. I stuck and fixed it.

[Embodiment 2] As shown in FIG.
Similar to Example 1, except that the intermediate strip near the edge of the wall base waterproof sheet 4 similar to the above is fixed to the outer wall member 2 mounting surface 3 of the pillar 1 and the stud 1A using double-sided adhesive tape or staples 6 and the like. Similarly, the outer wall material 2 is attached and fixed, and the extension end 4A,
4A was developed and piled up, and the double-sided tape 5A was used as appropriate for sticking and fixing.

[0013]

As described above, the present invention cuts the wall-base waterproof sheet 4 when the wall-base waterproof sheet is attached and the outer wall material is attached to the outer surface in a narrow place where the space with the adjacent land is very narrow. Without doing so, the intermediate strips are directly attached to the pillars 1 and the studs 1A in a vertical arrangement, so that the attaching work can be easily performed regardless of the narrow land. Further, since the extending ends 4A and 4A of the wall base waterproof sheet 4 are temporarily fixed to the outer periphery of the pillar 1 and the stud 1A, and the outer wall material is attached in that state, the space of the pillar 1 and the stud 1A can be effectively used. The outer wall material 2 can be carried out very easily. Also, the wall base waterproof sheet 4
After the temporary fixing, the outer wall member 2 can be temporarily attached and fixed to the entire wall surface, so that the work is simplified and the construction is facilitated. Furthermore, the wall-base waterproof sheet 4 has various effects such as good waterproofness on the back surface of the outer wall material 2 because it is superposed on the back surface of the outer wall board 2 and fixed by being attached.
