However, in the conventional waterproof structure 100 described above, when a wet outer wall such as mortar is used for the outer wall member 120, during the construction of the outer wall member 120, due to a hydration reaction of cement or the like that is a hardening component of the wet outer wall, As the outer wall member 120 shrinks with hardening, a gap t may be formed between the joint material 150 and the outer wall member 120, and there is a problem that rainwater enters the housing wall 30 side from the gap t.
Therefore, the joint material 150 can be configured by using an indeterminate material such as a sealing material that deforms following the contraction of the outer wall member 120. However, in this configuration, the waterproofing work becomes complicated and the construction cost increases. There is a problem of end.

  Further, in the outer wall member 120, the adhesion with the housing wall 30 is increased by the pressing force when the wall material of the wet outer wall is applied to the outer surface 30a of the housing wall 30, but the width direction of the outer wall member 120 (see FIG. 4), since the pressing force when the wall material is applied is not sufficiently applied, the adhesiveness of the joint surface in the width direction of the joint material 150 and the outer wall member 120 is lowered, and the joint material 150 and the outer wall There is a problem that a gap t is easily generated between the members 120.

  In addition, when the finishing material is sprayed onto the outer surfaces of the joint material 150 and the outer wall member 120 and coated, the finishing material cracks due to the difference in linear expansion coefficient due to the difference in the material of the joint material 150 and the outer wall member 120. There is a problem.

  Further, in order to enhance the waterproof performance between the sash frame member 10 and the outer wall member 120, the joint material 150 is extended from the inner surface side of the outer wall member 120 to a position where it is exposed to the outside. There is a problem that 150 deteriorates due to the influence of ultraviolet rays and the waterproof performance decreases.

  Therefore, in the present invention, the above-described problems can be solved, and the primary waterproofing between the mounting member and the wet outer wall and the secondary waterproofing between the mounting member and the housing wall can be performed simultaneously and easily. It is an object of the present invention to provide a waterproof structure for an attachment member capable of maintaining performance.

  According to this configuration, the inner surface of the butyl tape is pasted from the outer surface of the fin to the outer surface of the housing wall, whereby waterproofing between the mounting member and the housing wall is performed. Further, the outer surface of the butyl tape is attached to the inner surface of the wet outer wall, whereby waterproofing between the mounting member and the wet outer wall is performed. Thus, the primary waterproofing between the mounting member and the wet outer wall and the secondary waterproofing between the mounting member and the housing wall can be simultaneously and easily performed with one butyl tape.

  In addition, butyl tape is a known tape formed of non-vulcanized butyl rubber having adhesiveness, and has excellent durability and water resistance, and has good bondability with a wet outer wall. Since it joins reliably, high waterproof performance can be ensured.

  In addition, butyl tape is affixed to the inner surface of the wet outer wall, and even if the wet outer wall shrinks during construction, there is no gap between the butyl tape and the wet outer wall. Can be surely prevented. Moreover, since the pressing force when applying a wet outer wall is added to a butyl tape, the adhesiveness of a butyl tape and a wet outer wall can fully be improved. Thus, since waterproofing can be reliably performed by the butyl tape attached to the inner surface of the wet outer wall, it is not necessary to extend the butyl tape from the inner surface side of the wet outer wall to a position where it is exposed to the outside. Thereby, since the butyl tape is not affected by ultraviolet rays, high waterproof performance can be maintained.

  In addition, it is no longer necessary to interpose a waterproof member made of different materials around the wet outer wall, and when the wet outer wall is covered with a finishing material, the linear expansion coefficient of the covered part is constant, thus preventing cracks in the finishing material. be able to.

In addition, as an attachment member, for example, there is a sash frame member provided at the opening of the housing wall, but the configuration is not limited, and the present invention is applied to various members provided on the wet outer wall and the housing wall. can do.
Moreover, a wet outer wall is a wall material constructed | assembled using moisture, such as mortar, The structure is not limited.

According to the waterproof structure of the mounting member of the present invention, the primary waterproofing between the mounting member and the wet outer wall and the secondary waterproofing between the mounting member and the housing wall can be simultaneously and easily performed with one butyl tape. Therefore, the construction efficiency can be improved and the construction cost can be reduced.
In addition, the butyl tape is excellent in durability and water resistance, and has good bondability with the wet outer wall, and since the butyl tape and the wet outer wall are securely bonded, high waterproof performance can be ensured.
Furthermore, since waterproofing can be reliably performed with the butyl tape attached to the inner surface of the wet outer wall, it is not necessary to extend the butyl tape to a position where it is exposed to the outside. Thereby, since the butyl tape is not affected by ultraviolet rays, high waterproof performance can be maintained.
Further, it is not necessary to interpose a waterproof member made of different materials around the wet outer wall, and the coefficient of linear expansion of the portion covered with the finishing material becomes constant, so that the finishing material can be prevented from cracking.
