Description

[Technical Field]

[0001] The present invention relates to a waterproofing member for sealing off water at the joint between an exterior wall and the upper part of a wall such as a balcony attached approximately perpendicular to the exterior wall in a wooden house, and to a waterproofing structure using the same. [Background technology]

[0002] When constructing a balcony in a wooden house, a wainscot is constructed by extending the wainscot from the structural members that make up the exterior wall. At this time, the upper part of the joint between the wainscot and the structural member must be waterproofed to prevent rainwater and other elements from entering through the joint.

[0003] Patent Document 1 describes a waterproof structure for the joint between an exterior wall panel unit and a balcony railing wall. This waterproof structure achieves waterproofing by fitting the upper part of the balcony railing wall into a protruding portion that is U-shaped in cross section of a water stop plate (second waterproof sheet) fixed to the exterior wall panel unit. [Prior art documents] [Patent documents]

[0004] [Patent Document 1] Japanese Patent Application Publication No. 9-100568 Summary of the Invention [Problem to be solved by the invention]

[0005] The water stop plate in Patent Document 1 fits the top of the balcony railing wall into a U-shaped section in cross section, so the width of the balcony railing wall and the width of the U-shaped part of the water stop plate must match. For this reason, the same water stop plate cannot be used for balcony railing walls of different widths, so multiple water stop plates must be prepared to match the widths.

[0006] An object of the present invention is to provide a water-stopping member that has high construction efficiency and can be used for spandrel walls of various widths. [Means for solving the problem]

[0007] The water-stopping member of the present invention, which has been made to achieve the above-mentioned object, comprises a flat outer wall surface fixing portion having an L-shaped cutout, and a first waist wall water-stopping piece and a second waist wall water-stopping piece which protrude perpendicularly from the outer wall surface fixing portion along the cutout and are perpendicular to each other, and which are characterized in that the first waist wall water-stopping piece and the second waist wall water-stopping piece are corrugated. The present invention also provides a water-stopping structure for a joint between an exterior wall and a waist wall protruding at a right angle from the exterior wall, using two of the water-stopping members, wherein one of the water-stopping members abuts the exterior wall surface fixing portion against the exterior wall, the first waist wall water-stopping piece against the upper surface of the waist wall, and the second waist wall water-stopping piece against one side of the waist wall, and the other water-stopping member abuts the exterior wall surface fixing portion against the exterior wall, the first waist wall water-stopping piece against the other side of the waist wall, and the second waist wall water-stopping piece against the upper surface of the first waist wall water-stopping piece of one of the water-stopping members. [Effects of the Invention]

[0008] The present invention provides the following effects by solving the above-mentioned problems. (1) By adjusting the overlap between the first waist wall waterstop piece of one waterstop member 1 and the second waist wall waterstop piece of the other waterstop member, the distance between the second waist wall waterstop piece of one waterstop member and the first waist wall waterstop piece of the other waterstop member, which is the width of the waist wall, can be adjusted.Therefore, by combining two waterstop members, it is possible to accommodate waist walls of various widths. (2) By configuring the first waist wall waterstop piece and the second waist wall waterstop piece of the waterstop member in a corrugated shape, when rainwater penetrates from the lower end of the second waist wall waterstop piece located above into the gap between the second waist wall waterstop piece located below and the first waist wall waterstop piece located below, the shape of the waves provides resistance in the same direction as the waves of the corrugated plates, preventing penetration. [Brief explanation of the drawings]

[0010] The present invention will be described in detail below based on the embodiments shown in the drawings. [Example]

[0011] [1] Water-stopping material configuration The water-stopping member 1 of the present invention is a combination of resin plate materials and consists of an exterior wall surface fixing portion 11, and a first waist wall water-stopping piece 12 and a second waist wall water-stopping piece 13 that protrude perpendicularly from the exterior wall surface fixing portion 11 (Figure 1). The outer wall surface fixing portion 11 has an L-shaped cutout 111, and the first waist wall water stop piece 12 and the second waist wall water stop piece 13 are protruded along the cutout 111 and are perpendicular to each other. In addition, the first waist wall water stop piece 12 and the second waist wall water stop piece 13 are configured in a corrugated plate shape with the wave direction parallel to the outer wall surface fixing part 11.

[0012] [2] Water-stopping structure using water-stopping materials (1) Target structural materials The waterproof member 1 of the present invention is used to waterproof the joint between an exterior wall 2 of a wooden house and a spandrel wall 3 protruding from the exterior wall 2. The components of the waterproofing member 1 are fixed to an exterior wall 2 or a waist wall 3 with waterproof tape 4. Waterproof paper is then laid on top of the fixed waterproofing member 1, and a mortar finish, siding, etc. are then placed to form the wall surface of a wooden house.

[0013] (2) Arrangement of water-stopping components The water-stopping structure of the present invention is configured using two water-stopping members 1 (FIGS. 2 and 3). One of the water-stopping members 1a is positioned so that the outer wall surface fixing portion 11a abuts against the outer wall 2, the first waist wall water-stopping piece 12a abuts against the upper surface 31 of the waist wall 3, and the second waist wall water-stopping piece 13a abuts against one side surface 32 of the waist wall 3. The other water-stopping member 1b is positioned so that its outer wall surface fixing portion 11b abuts against the outer wall 2, its first waist wall water-stopping piece 12b abuts against the other side surface 33 of the waist wall 3, and its second waist wall water-stopping piece 13b abuts against the upper surface of the first waist wall water-stopping piece 12a of the water-stopping member 1a already positioned on the upper surface 31 of the waist wall 3. By adjusting the overlap between the first waist wall waterstop piece 12a of one waterstop member 1a and the second waist wall waterstop piece 13b of the other waterstop member 1b, the distance between the second waist wall waterstop piece 13a of one waterstop member 1a and the first waist wall waterstop piece 12b of the other waterstop member 1b, which is the width of the waist wall 3, can be adjusted, and therefore, by combining two waterstop members 1a and 1b, it is possible to accommodate waist walls 3 of various widths.

[0014] (3) Effect of the shape of the waist wall water stop The first waist wall waterstop piece 12 and the second waist wall waterstop piece 13 of the waterstop member 1 are formed in a corrugated plate shape. Therefore, the first waist wall waterstop piece 12a of one waterstop member 1a and the second waist wall waterstop piece 13b of the other waterstop member 1b are arranged on the upper surface 31 of the waist wall 3 with the waves of the corrugated sheets overlapping each other. When rainwater seeps from the lower edge of the upper second waist wall waterstop piece 13b into the gap between it and the lower first waist wall waterstop piece 12a, the wave shape provides resistance and prevents the water from seeping in the same direction as the waves of the corrugated sheet. Also, because the exterior wall surface fixing parts 11a, 11b are located in the direction parallel to the waves, the rainwater does not seep into the exterior wall 2. [Explanation of symbols]
