Description

[Detailed description of the invention] (Industrial application field) The present invention relates to a joint structure at an inside corner of an outer wall.

(Prior Art) Conventionally, as a joint structure at an inside corner of an outer wall, there is, for example, the one shown in FIG. 8 of Japanese Patent Application Laid-Open No. 64-39444.

In this joint structure, a joint closing material made of an elastic material such as rubber is placed in the joint at the corner of the outer wall to fill the gap and close the joint. That is, the joint closing material should have a width suitable for the joint width.

(Problem to be solved by the invention) However, in such a conventional joint structure,
Since joint sealing materials cannot tolerate variations in the joint width at the inside corners due to dimensional errors that occur during the manufacturing of the exterior wall or positional errors that occur during installation, several joint sealing materials with different widths are prepared and the joint widths are adjusted accordingly. A joint sealing material with an appropriate width must be selected and used. Therefore, it is necessary to keep a large amount of joint sealing materials in stock at all times.

In addition, if the joint sealing material of the appropriate width for the joint width of the corner joint being constructed runs out, no further construction can be carried out, and if it is out of stock, construction will be postponed until the next stock arrives. This will result in Especially in areas where the number of construction projects is small, it is difficult to keep a large number of joint sealants in stock at all times due to the frequency of use.

The present invention has focused on the above-mentioned conventional problems, and an object of the present invention is to provide a joint structure that can tolerate variations in the joints of inside corners caused by dimensional errors, positional errors, etc. of the outer wall.

(Means for Solving the Problems) In order to solve the above problems, the joint structure of the present invention has a joint structure in which a joint closing material is attached to a joint in an inside corner consisting of a first outer wall and a second outer wall. The joint closing material is composed of a first closing material made of a hard material and a second closing material made of two hard members connected by a soft sheet,
The first occlusion material is fixed to the first outer wall, and the second occlusion material has two hard members overlapping each other, one of which is fixed to the second outer wall and the other hard member is fixed to the first outer wall.
It is connected to the occlusion material.

In the joint structure, it is preferable that the back side between the side edge of the first outer wall and the side edge of the second outer wall is covered with a waterproof sheet with a zipper.

(Function) In the joint structure of the present invention, the joint closing material is composed of a first closing material made of a hard material and a second closing material made of two hard members connected by a soft sheet, The first occlusion material is fixed to the first outer wall, and the second occlusion material has two hard members overlapping each other, one of which is fixed to the second outer wall and the other hard member is fixed to the first outer wall. Since it is connected to the material, the overall width of the second closing material can be adjusted by the overlapping width of the hard members, and variations in the joint can be tolerated.

In addition, in a joint structure in which the back side between the side edge of the first outer wall and the side edge of the second outer wall is covered with a waterproof sheet with a zipper, it is possible to prevent rainwater from entering the indoor side from the joint. This can be prevented with a waterproof sheet with a zipper.

(Example) Embodiments of the present invention will be described below based on the drawings.

First, the configuration of this embodiment will be explained.

Hereinafter, 1 will be referred to as a first outer wall, and 2 will be referred to as a second outer wall.

The first outer wall 1 and the second outer wall 2 are erected at right angles to form a corner on the front side, and a joint closing material 3 is attached to the joint of the corner.

The joint closing material 3 is a first closing material 31 made of a hard material.
and the two hard members 321 and 322 are connected to a soft sheet 323.
and a second closing material 32 connected by.

The first closing material 31 is bent in three different directions. Note that one side of the bent portion is formed at a right angle, and the other side is formed at approximately 135°. Then, this first closing material 31 is fixed at an angle of 135 degrees by fixing the end of the bent portion side formed at a right angle along the surface of the first outer wall 1 with double-sided adhesive tape 4 and wood screws 5. The end on the bent side protrudes into the joint.

The hard members 321 and 322 of the second closing member 32 are both bent into an L shape. And the other hard member 3
21, one side edge of the hard member 321 is fixed to the surface of the second outer wall 2 with double-sided adhesive tape 4 and wood screws 5 with the inside corner side facing the front side, and the other hard member 322 is fixed with the outside corner side facing the front side. One side edge is fixed to the surface of the first closing material 31 with a double-sided adhesive tape 4 while facing the front side. In addition, two hard members 3
21 and 322 are provided in an overlapping state.

The soft sheet 323 has one end fixed to the back surface of the hard member 321 fixed to the second outer wall 2, and the other end fixed to the back surface of the hard member 322 fixed to the first obturator 31. Then, the soft sheet 323 is attached to the hard members 321 and 32.
2, double-sided adhesive tape γ is used. Further, the soft sheet 323 is preferably waterproof, such as a rubber sheet, a soft polyvinyl chloride sheet, or a polyethylene sheet.

Further, the back side between the side edge of the first outer wall 1 and the side edge of the second outer wall 2 is covered with a waterproof sheet 6 with a zipper.

The zippered waterproof sheet 6 is composed of a first waterproof sheet 61 fixed to the back surface of the first outer wall 1 and a second waterproof sheet 62 fixed to the back surface of the second outer wall 2. Stops 63 and 64 are provided at the ends of the sheet 61 and the second waterproof sheet 62 to fit into each other. Note that, like the flexible sheet 323, the waterproof sheet 6 with a fastener is made of a soft material such as a rubber sheet, a soft polyvinyl chloride sheet, or a polyethylene sheet. Also,
Double-sided adhesive tape 7 is used as a means for fixing the first waterproof sheet 61 and the second waterproof sheet 62 to the first outer wall 1 and the second outer wall 2.

Next, the operation of this embodiment will be explained by comparing the joint structures shown in FIGS. 1 to 3.

I can do it. That is, when the joint width is small, the overlapping width of the hard members 321 and 322 is increased to narrow the overall width of the second closing material 32, and when the joint width is large, the overlapping width of the hard members 321 and 322 is decreased. and second
In addition, in the drawing, in order to maintain the overlapping state of the hard members 321 and 322 of the second occlusion material 32, the hard member 322 fixed to the first occlusion material 31 is
is shifting its position. In addition, hard members 321°322
Even if the overlapping width of the hard members 321 and 322 changes, since the space between the hard members 321 and 322 is covered by the soft sheet 323, the airtightness between them is always ensured.

In other words, the joint structure of this embodiment provides the following effects.

■ The second obturator 3 is formed by the overlapping width of the hard members 321 and 322.
Since the overall width of 2 can be adjusted and variations in joint width can be tolerated, there is no need to stock a wide variety of joint sealants 3 with widths that correspond to various joint widths, reducing waste, especially in areas where the number of construction projects is small. It disappears.

■ Since the back side between the side edges of the first outer wall 1 and the side edges of the second outer wall 2 is covered with a waterproof sheet 6 with a zipper, the waterproof sheet with a zipper prevents rainwater from entering the room through the joints. This can be prevented with the sheet 6.

■ Seal the joint sealant 3 with double-sided adhesive tape 4 and wood screws 5.
Since the dry type 1 method is applied by fixing to the outer wall 1 and the second outer wall 2, and fixing the waterproof sheet with a zipper 6 to the first outer wall 1 and the second outer wall 2 with double-sided adhesive tape 7,
Construction can be carried out quickly without requiring a large number of units.

Although the embodiments of the present invention have been described above based on the drawings, the specific configuration is not limited to these embodiments.
Even if there are design changes that do not depart from the gist of the present invention, they are included in the present invention.

For example, in the example, the joint sealing material is fixed to the first and second outer walls with double-sided adhesive tape and wood screws, and the waterproof sheet with a zipper is fixed to the first and second outer walls with double-sided adhesive tape. However, a wet method using an adhesive instead of double-sided adhesive tape or wood screws may also be applied.

Moreover, the shapes of the first occlusion material, the second occlusion material, etc. are not limited to the embodiments.

(Effects of the Invention) As explained above, in the joint structure according to claims 1 and 2 of the present invention, the overall width of the second closing material is adjusted by the overlapping width of the hard members, and the variation in joint width is reduced. This eliminates the need to stock a wide variety of joint closing materials with widths corresponding to various joint widths, which eliminates waste, especially in areas where the number of construction projects is small.
