Description

Description: TECHNICAL FIELD The present invention relates to a waterproof structure of an opening for protecting the opening from rainwater leakage at the lower end of a sash of a wooden building.

[Conventional technology]

The sash mounting opening of a wooden building is composed of a lintel, a lintel, a window sill, and a vertical frame and upper and lower frames around it. ing. Then, as shown in FIG. 4, the sash 15 is fitted into the sash mounting opening 14 from the outside, and the sash 15 is nailed to the surrounding wall underlaying plywood 17 at the flange 16. After that, on the front surface of the collar 16, a waterproof paper 19 is attached via a double-sided adhesive tape 18 so as to extend to the surrounding wall underlaid plywood 17, so as to prevent rainwater from entering inside, and a metal lath 20 is applied thereon. The outer wall is finished with mortar 21.

[Problems to be Solved by the Invention]

However, the water-tightness of the mortar 21 is not sufficient, and in addition to the infiltrating rainwater, there is rainwater that also enters inside through the boundary surface between the mortar 21 and the sash 15, and such infiltrating rainwater around the sash will again be sashed. 15 drops of water 15a
For example, some of them flow to the front surface, but many of them flow down the outer surface of the sash 15 and flow down to the lower end portion of the collar 16.

By the way, as shown in FIG. 5, the sash 15 includes the upper frame 2
2 and the left and right vertical frames 24 and 25 of the lower frame 23 are combined to form a packing 2 between the frame members.
6 and 27 are provided to keep the inside and outside of the sash watertight. However, as shown in FIG. 6, the packings 26 and 27 are provided at the lower end of the sash flange 16 with the sash collar 16 as shown in FIG.
1 to 2 mm from the surface, no matter how the double-sided adhesive tape 18 for adhering the waterproof paper 19 is pressed,
Since hole-shaped gaps 28 are formed on both sides of the packings 26, 27, most of rainwater flowing down from the outer side surface 15b of the sash flows down from the gaps 28 as it is and the collar 1
There was a problem in that the wall main body such as the wall underlaying plywood 17 was wet around the lower edge of No. 6 and the like.

Further, during assembly of the sash 15 or installation of the sash 15, an excessive force is applied to the sash 15 so that the packings 26 and 27 of the sash 15 are displaced or damaged.
Alternatively, if the gap between the frame members becomes large and the packing becomes unusable, the rainwater that wets the inner side surface 15c of the sash 15 and flows down will infiltrate to the outer surface side from such a defective packing portion, and the sash collar 16 There is a problem in that the main body of the wall underlaying plywood 17 or the like on the back side of the above, or the window stand 28 or the like is wet and corroded.

In view of the above situation, the present invention is that rainwater that enters the sash periphery and flows down along the outer surface of the sash flows down from the gap at the packing point at the lower end of the collar of the sash to wet the wall main body or the inner surface of the sash. The purpose is to provide a waterproof structure for the sash mounting opening so that rainwater that flows down along the water will not enter the outer surface side from the inner surface side and wet the wall body or the window sill at the location where the packing is defective, and will not corrode. .

[Means for Solving the Problems] In order to achieve the above object, the present invention provides a flat sheet portion, a side sheet portion that rises at a right angle from an edge of the flat sheet portion, the side sheet portion, and the flat surface. Waterproof parts integrally formed of a soft waterproof material are formed on the left and right lower parts of the sash and on the left and right lower parts of the sash, and the front part of the seat is formed at right angles to both sides of the seat extending from both sides to the back. It is interposed between the right and left corners of the corresponding sash mounting opening, and waterproof paper is interposed between the waterproof component and the lower wall surface of the sash mounting opening, or a flat sheet portion and Left and right side sheet parts that rise at right angles from both left and right edges of the flat sheet part, and a front sheet part that is perpendicular to each of the left and right side sheet parts and the flat sheet part so that their respective faces extend to the back. And from And a waterproof component integrally formed of a soft waterproof material is interposed between the lower portion of the sash and the sash mounting opening corresponding to the lower portion of the sash, and the waterproof component and the sash mounting opening are A waterproof paper is interposed between the lower wall surface and the flat sheet portion and the side surface sheet portion of the waterproof component are preferably folded at an edge opposite to the front sheet portion side. The invention proposes a waterproof structure of a sash mounting opening in which a water repellent shape is formed.

[Action]

When the sash is attached to the sash mounting opening, the waterproof parts are used in a pair of left and right.In the case of claim (1), first, the waterproof parts are provided in the left and right corners of the sash mounting opening, respectively. The flat sheet portion is placed on the window stand, the side surface sheet portion is in contact with the side surface of the opening such as the lintel receiver, and the front sheet portion is closely attached from the outside so as to cover the wall surface, that is, the wall lining plywood or the like. Next, the front sheet portions of the left and right waterproof components are rolled up, waterproof paper is inserted into the back surface thereof, and the front sheet portions are returned to their original positions. After that, the sash is fitted into the sash mounting opening from the outside, and is nailed with the collar portion. Next, waterproof paper is applied through a double-sided adhesive tape over the surfaces of the wall surface adjacent to the respective surfaces of the sash upper part and the left and right rims. After that, around the sash, metal lath is applied like other general wall surface portions, and mortar is applied to complete the finish.

In the one using the integral type waterproof component having side sheet portions on the left and right sides, the flat sheet portion of the waterproof component is placed on the window stand of the sash mounting opening, and the left and right side sheet sheets are used. The part is in contact with both sides of the opening, and the front sheet part is closely attached from the outside so as to cover the wall surface such as the plywood under the wall. Then, the front sheet portion is rolled up, waterproof paper is inserted into the back surface of the front sheet portion, and the front sheet portion is returned. Further, the sash is fitted into the sash mounting opening from the outside, and is nailed at the flange portion. Subsequent construction of waterproof paper around the sash and construction of metal lath and mortar are carried out in the same manner as in the case of using the pair of left and right waterproof parts.

Therefore, even if rainwater around the sash flows along the outer surface of the sash and flows down as it is at the packing point at the lower end of the sash collar, rainwater that flows down the inner surface of the sash will still flow from the defective packing point to the outer surface of the sash. Even if it gets wet, the rainwater moves to the surface of the waterproof component and flows along the surface of the waterproof paper, so that the rainwater is discharged to the outside without wetting the wall body.
