DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for mounting a waterproof sheet on a basement of a wall.

[0002]

2. Description of the Related Art Conventionally, when an external wall material such as a wall plate is fixed to a pillar or stud surface, first, a wall base waterproof sheet is attached on the envelope surface of the pillar or stud, and then the outer wall material is appropriately applied to the surface. Sticking and fixing are performed by means. However, if the outside of the wall to be constructed is a narrow land with a very narrow gap with the adjacent land, the wall material cannot be carried in from the outdoor side, so if the wall base waterproof sheet is pasted, the outer wall material will be transferred from indoor to outdoor. Unloading becomes impossible, and fixing of the outer wall material becomes impossible.

Therefore, conventionally, in such a case, FIG.
A waterproof sheet B is adhered to the position where one sheet of outer wall material A is to be attached as shown in FIG. 1, and then the outer wall material A is carried out from the indoor side onto the waterproof sheet B, and the fixing bracket E is fixed to the envelope surface of the pillar and stud C.
The waterproof sheet B having a width twice or three times the width of the outer wall material A is attached as shown in FIG. After a cut F is made to protrude the mounting bracket E, the outer wall material A is fixed by the metal fitting E passing through the cut F.

[0004]

However, in the case of the means shown in FIG. 5, it is necessary to prepare a waterproof sheet B corresponding to the width of the outer wall material A. Usually, the width of the waterproof sheet B is equal to the width of the outer wall material A. Since the width is twice to three times the width, it is very troublesome to cut a long waterproof sheet at a construction site, and there is a disadvantage that the construction is difficult. In addition, in the case of this construction method, it is necessary to alternately perform the operation of attaching the wall base waterproof sheet B and the operation of attaching the outer wall material A, so that the operation is a repetitive operation, which is very troublesome, and has a disadvantage of poor efficiency.

[0005] In the case of the fixing means shown in Fig. 6, although the labor of cutting the waterproof sheet B can be omitted, a cut F for the fixing bracket E needs to be provided on the waterproof sheet B. There was a disadvantage 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 that the waterproof sheet B is caught and broken easily occurs, and there is a disadvantage that the work is very difficult.

[0006]

SUMMARY OF THE INVENTION In view of the above problems, the present invention can efficiently and waterproofly attach a waterproof sheet and an outer wall material to a narrow land where a gap between adjacent land is narrow. The purpose of the present invention is to provide a method of attaching a waterproof base sheet.

[0007]

That is, according to the method of mounting the waterproofing sheet on the base of the wall according to the present invention, 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 is provided. The wall base waterproof sheet 4 is vertically arranged, and the width direction both ends are extended to the outer wall material 2 mounting surface 3 of the pillar 1 and the stud 1A, and the intermediate band is attached thereto, and the extended ends 4A, 4A are The outer wall material 2 is fixed to the pillar 1 and the stud 1A by being wound around the outer periphery of the pillar 1 and the stud 1A, and then the temporarily fixed wall base waterproof sheet 4 is developed and made to extend along the back surface of the outer wall material 2. In addition, the extension ends 4A and 4A are overlapped and fixed on the back surface of the outer wall material 2.

[0008]

According to the present invention, the wall base waterproof sheet 4 is a belt-like body 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. Pasted. Then, since the wall base waterproof sheet 4 is wound around 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 outer wall can be used without damaging the wall base waterproof sheet 4 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 extending 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 sheet 4 extending from the adjacent pillars 1 and the studs 1A overlaps on the back surface of the outer wall material 2 and is adhered and fixed in this state, the waterproofing of the back surface of the outer wall material 2 becomes complete.

[0009]

Next, an embodiment of the present invention will be described. 1 to 4 are plan views showing an embodiment of the method of the present invention.

[Example 1] As shown in FIG. 1, a 1 m-wide wall base waterproof sheet 4, such as an asphalt-impregnated felt and a breathable waterproof sheet, which is conventionally used in general, is vertically arranged.
The central part in the width direction is stuck and fixed to the outer wall material 2 mounting surface 3 of the pillar 1 and the stud 1A using a double-sided adhesive tape or a staple 6, and the extending ends 4A and 4A on both sides are fixed to the pillar 1 and the stud 1.
A was wrapped around the outer periphery and temporarily fixed with an 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 material 2 was provided at a key point of the underlayer waterproof sheet 4, and the fitting was passed through the slit through the fitting head, and the base was fixed to the side surface of the pillar 1 and the stud 1A.

Next, as shown in FIG. 2, the pillar 1, the stud 1A
The outer wall material 2 is carried out from the space using the space opened from the indoor side, and is fixed to the surfaces of the pillars 1 and the studs 1A, and the outer wall material reaches the height corresponding to the width of the wall base waterproof sheet 4 (in the paper back direction in FIG. 2). Material 2 was attached and fixed. Next, the temporarily-fixed waterproof base sheet 4 is released, and the extended ends 4A, 4A are developed along the back surface of the outer wall material 2 as shown by dotted arrows in FIG. And fixed.

[Embodiment 2] As shown in FIG.
Example 1 except that the intermediate band near the end of the wall base waterproof sheet 4 similar to that of Example 1 was fixed to the outer wall material 2 mounting surface 3 of the pillar 1 and the stud 1A using a double-sided adhesive tape or a staple 6 or the like. Similarly, the outer wall material 2 is attached and fixed, and the extended end 4A,
4A was developed and stacked, and was appropriately fixed and adhered using double-sided tape 5A.

[0013]

As described above, according to the present invention, when the waterproof base sheet is adhered to the narrow ground where the space between the adjacent grounds is very narrow, and the outer wall material is affixed to the outer surface thereof, the waterproof base sheet 4 is cut. Since the intermediate band is stuck on the pillar 1 and the stud 1A as it is in the vertical arrangement without performing, the sticking work can be easily performed regardless of the narrow land. In addition, the extending ends 4A, 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 stuck in that state, so that the space of the pillar 1 and the stud 1A is effectively used. This makes it very easy to carry out the outer wall material 2. In addition, the wall base waterproof sheet 4
After the temporary fixing, the outer wall material 2 can be attached and fixed to the entire wall surface at a time, so that the operation is simplified and the construction is facilitated. Furthermore, since the wall base waterproof sheet 4 is superposed and fixed on the back surface of the outer wall plate 2, it has various effects such as good waterproofness of the back surface of the outer wall material 2.
