Description

The present invention relates to a draining construction method for discharging rainwater that is disposed in a building and has flowed down along the surface of an outer wall material to the front.

  Conventionally, a drainer is a horizontally long shape manufactured by cutting and bending a metal plate, and prevents the rainwater flowing down the surface of the building's outer wall from entering the building. Between the outer wall plates arranged on the upper and lower sides, and the like.

  For example, Non-Patent Document 1 discloses a mounting wall portion fixed by a nail or the like, an inclined protruding wall portion bent obliquely forward and downward from a lower end of the mounting wall portion, and bent downward from a front end of the inclined protruding wall portion. A drainer comprising a protruding end wall portion is disclosed. And fixing the mounting wall to the base of the building with a nail, fixing the drainer to the base of the building, and thereby guiding the rainwater flowing down along the outer surface of the outer wall It is described that it is dropped.

  Further, Patent Document 1 discloses a drainer including a mounting portion formed by bending a thin vinyl chloride steel plate into a Z shape in a sectional view and a draining portion formed at the lower end of the mounting portion. The draining portion is arranged so as to be inclined from the back surface side of the exterior material to the front surface side from the lower end of the attachment portion toward the upper surface portion of the lower exterior material, and covers the upper end surface of the exterior material. An extension portion, another extension portion extending downwardly from the tip portion of the extension portion along the surface of the exterior material, and covering the upper end portion of the surface of the exterior material, and the tip end of the other extension portion And a protrusion that extends upward from the portion toward the back side of the exterior material. Then, the attachment portion is inserted between the upper exterior material and the lower exterior material, and a fixing material such as a screw is driven into and fixed to the attachment portion. It describes that water such as rainwater can be prevented from entering the back side of the lower exterior material.

  Further, Patent Document 2 includes a mounting portion that is made of a single long surface material and is attached to the outer wall main body, an inclined surface that is bent from the mounting portion, and an exposure that is further bent from the inclined surface. A drainer composed of a surface is disclosed. And it is disclosed that the drainage is waterproofed by disposing the drainer in a lower connection part where the outer wall and the lower house are connected.

  In this way, the drainer is constructed at the base of the building, between the outer wall plates arranged on the top and bottom, and the connecting part where the outer wall and the lower house are connected, thereby flowing down the surface of the outer wall material. The rainwater that has been discharged is discharged forward.

  As common to all construction structures, a moisture-permeable waterproof sheet is disposed between the outer wall plate and the structural casing, thereby waterproofing the structural casing. The moisture-permeable waterproof sheet is provided so as to cover a part of the surface of the drainer fixed to the structural housing, and usually the lower end of the moisture-permeable waterproof sheet is attached to the drainer with an adhesive tape. . In order to prevent the moisture-permeable waterproof sheet from fluttering by wind or to prevent rainwater from entering from the lower side due to blowing back, the adhesive tape is provided over the entire longitudinal direction of draining. It is pasted so as to close the lower end.

  For this reason, the work of sticking the adhesive sheet to the drainer takes time. Further, when the application position of the moisture permeable waterproof sheet or the adhesive tape is corrected, there is also a problem that the moisture permeable waterproof sheet is easily broken because the adhesive tape and the moisture permeable waterproof sheet are firmly bonded. Furthermore, since it is difficult to correct the position where the moisture permeable waterproof sheet or the pressure-sensitive adhesive tape is applied, there is also a problem that it cannot be corrected even if wrinkles occur when the moisture permeable waterproof sheet is applied.

  Therefore, Patent Document 3 discloses a drainer in which an adhesive tape such as a double-sided adhesive tape is attached in advance to the front surface of an attachment portion serving as a fixed base for draining.

  According to the draining of patent document 3, since the adhesive tape is previously affixed on the front surface of the attachment portion, the work is reduced. However, the problem that the moisture permeable waterproof sheet is easily broken when the application position of the moisture permeable waterproof sheet or the adhesive tape is corrected has not been solved, and it cannot be corrected even if wrinkles occur when the moisture permeable waterproof sheet is applied. This problem cannot be solved.
