[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a joint sealing structure and a joint sealing method between finishing materials attached to a building.

[0002]

2. Description of the Related Art Heretofore, the following structure has been generally used as a sealing structure for a joint between finishing materials attached to a building.

First, a joint seal structure between exterior materials used for the outer wall of a building will be described as an example.

As a joint sealing structure between exterior materials which are attached to a mounting member of a building to construct an outer wall, generally known is a wet sealing material which is applied inside the joint and fills the inside of the joint. ing.

In addition, a joiner 80 as shown in FIG.
There are some that fill the inside of the joint. Joiner 80
Is a dry type having an I-shaped cross section having a leg portion 82 filling the inside of the joint portion and a building attachment portion 84 provided at the lower end of the leg portion 82, and is attached to the member 90 on the building side in advance, The exterior materials 82a and 82b are attached to the building-side member 90 so as to sandwich the leg portions 82 of 80 from both sides, thereby filling the joint between the exterior materials 82a and 82b.

On the other hand, in the joint structure between the roof finishing materials used for the roof part, the joint structure made of the sealing material has a problem in durability due to the severe condition of the roof. A laid structure was used in which waterproof paper was laid on top of which a steel plate roof was attached, and the waterproof paper and the steel plate roof were partially overlapped at the joint. In this case, from the viewpoint of simplifying on-site work and promoting industrialization, a method of manufacturing a roof panel to which a finishing material is attached in advance in a factory or the like and transporting and assembling to the site is used.

[0007]

However, in the case of the joint structure between the finishing materials, the following problems have occurred.

In the case of a structure in which the above-mentioned joint between the exterior materials is filled with a wet sealing material, the construction work requires treatment work such as masking and spatula finishing, which requires many steps.
There is a problem that the workability is poor, and the wet type sealing material becomes poor in appearance because it becomes thin over time, and there is a problem in terms of durability.

Next, in the case of the structure in which the joint portion is filled with the joiner 80, there is a problem that the cost is high.

On the other hand, in the case of a joint structure between roof finishing materials,
The waterproof paper and the iron plate roof attached to the roof panel are attached so as to project from the end portion on the joint side of the roof panel by the amount overlapped at the joint portion. The workability is poor due to the presence of the protruding portion during the on-site transportation, and the waterproof paper may be damaged during the transportation.

Further, even at the site, the work of mounting the roof panel with the finishing material while sequentially stacking the finishing materials is sometimes a high place, which is a complicated work.

The present invention has been made in view of the above problems, and an object thereof is a joint seal structure and a joint seal between finishing materials which can simplify the construction work and have high durability and low cost. To provide a method.

[0013]

In order to achieve the above-mentioned object, the invention according to claim 1 is a joint portion seal structure between each finishing material attached to a building, wherein the back surface side of the joining end of each said finishing material is provided. It is applied to a gap formed by a continuously formed notch portion that spreads in a taper shape toward the back side, the notch portions of both finishing materials, and a finishing material attachment member on the building side, and fills the gap. And a sealing material.

Since it can be formed, a highly waterproof seal structure can be obtained by a simple operation of filling the gap with a sealing material. The sealing material is applied to the void located on the building side in the joint, but when the sealing material is applied to the void, the taper surface of the continuously formed notched part that spreads toward the back side is applied. Since the material is pushed toward the back side of the finishing material and the gap is expanded to the back side, the sealing material is not extruded onto the surface of the exterior material, and it is necessary to perform complicated processing work after applying the sealing material. Therefore, the problem of simple and easy construction work can be solved.

Further, since the sealing structure can be made only by the sealing material and a relatively expensive fixed material such as a joiner is not used, the problem of cost reduction can be solved.

Further, since the contact surface of the sealing material is larger than that of the conventional example, the sealing performance can be improved,
Since the exposed surface of the sealing material can be small, it is possible to prevent the sealing material from becoming thin, and it is possible to solve the problems of good appearance and ensuring durability.

According to the second and fifth aspects of the present invention, the finishing material of the panel with the finishing material has the taper-shaped continuously formed notch portion that widens toward the back surface side on the back surface side of the joining end. In the case of panels with finishing materials, it is possible to obtain the same sealing structure as above, and it is also possible to perform sealing between finishing materials at the same time as joining panels with finishing materials, making workability of construction work even better. improves.

According to the third aspect of the present invention, the finishing material of the roof panel with the finishing material has a tapered notch formed on the rear surface side of the joining end, the taper shape extending toward the rear surface side. High waterproofness due to the double seal structure that fills the gap between the roof panel formed by the notch with the sealing material, covers the joint with a cover, and fills the gap between the finishing material and the cover with the sealing material. Even in the roof part where is required, it is possible to obtain a sealing structure between the finishing materials having sufficient durability. Like the conventional example,
No need to stack waterproof paper and iron roof, and roof panels with finishing materials can be easily transported from the factory compared to conventional waterproof paper and iron roof that protrude from the edge of the roof panel. The problem of easy construction can be solved. In addition, since the finishing material can be directly attached to the core material that constitutes the roof panel, a base plate, waterproof paper, etc. are not required, and the cost can be reduced.
