Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a board, for example, a sandwich board in which a plastic core material is integrally interposed between thin metal plates, or a joint structure for forming a wall by combining boards made of a hollow body, a solid body or the like. It is about.

2. Description of the Related Art As this conventional joint structure, Japanese Utility Model Publication No. 3-7469 and Japanese Utility Model Publication No. 3-12901 are known.

[0003]

However, in the structure of (3), since the joint cover and the siding plate are directly connected and both member surfaces are in direct contact with the inside and outside air, heat conduction is extremely good. However, not only dew condensation was generated, but also it was not possible to attach the floor covering to the furring strip from the back side, and it was necessary to install an expensive scaffold.

Further, in the above, there is a disadvantage that the board cannot be mounted from the inner surface and the joint portion is not waterproof.

[0005]

In order to eliminate such drawbacks, the present invention can apply a caulking material by applying a caulking material to the furring strip from the inside and mounting a caulking material base. Joints that are easy to apply by simply applying a thin finish, can form a beautiful appearance, have no direct conduction of internal and external air, do not generate dew condensation, and have the advantage of being compatible with the board thickness. It proposes a structure.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of a joint structure according to the present invention will be described in detail below with reference to the drawings. That is, FIG. 1 is an explanatory view showing the joint structure, where A is a fitting, B is a receiver, C is a backup material, D is a sheet material, E is a caulking material, F is a board, G is a joint portion, and α is Is the body.

To further explain, the mounting bracket A is a deformed body having an inverted T-shaped cross section and formed in a long shape from the engaging portion 1 and the L-shaped mounting portion 4 which are provided in a protruding manner as shown in FIG. Then, the end portion of the board F is mainly placed to form the joint portion G, and the receiver B is engaged in correspondence with the thickness of the board F.

That is, the locking portion 1 is formed of a top surface 2 for mounting the backup material C, a locking claw portion 3 for locking the guide of the board F and the engaging claw 8 of the receiving body B. Yes, the mounting portion 4 extends the lower end of the locking portion 1 to the outside, and at least one protrusion 5 parallel to the locking portion 1 is provided on the way.
It is configured by a mounting piece 6 for mounting the mounting metal fitting A on the skeleton α by hanging its end edge inward. Reference numeral 7 denotes a mounting hole, which is useful for mounting the mounting bracket A on the frame α.

Further, the receiver B has a locking portion 1 as shown in FIG.
The engaging claw 8 is elastically engaged with the engaging claw portion 3, the elastic leg 9, and the mounting surface 10 of the caulking material E or the like, and is a short or long body formed by molding a thin metal plate. The receiving body B has an engaging structure that can be easily adjusted in accordance with the height dimension H of the joint portion G in accordance with the thickness T of the board F.

As shown in FIG. 4, the backup material C is, for example, a plastic foam, rubber-based or synthetic rubber-based elongated body and has a circular, rectangular or elliptical cross section, and is equal to the joint width W or from this dimension. It is somewhat large and closes the space between the end faces of both boards F under elasticity, and caulking material E used for joint G
The filling amount of the caulking material E is reduced, and the caulking material E is effectively filled.
The airtightness is added and the cost is reduced.

The sheet material D has one function such as a bond breaker, a waterproof material, and a caulking material adhering surface, and is made of a plastic sheet, a rubber sheet, a metal foil sheet, a low foam sheet, a laminated material of paper and this type of sheet, and the like. It is a thing.

The caulking material E is composed of silicone, modified silicone, foamable caulking material, and known materials,
It has weather resistance and waterproofness. The filling portion is to fill the space between the ends of the board F and the space surrounded by the backup material C and the surface material of the board F.

As shown in FIG. 5, the board F is formed by integrally forming a front surface material 12, a back surface material 13, and a core material 14,
Thin metal plates are used as the front and back materials 12 and 13, and the core material 1
As for 4, a plastic foam or the like is integrally used.

Next, the construction method of the joint structure according to the present invention will be briefly described. That is, the mounting metal fitting A is provided on a base of a wooden structure or a steel frame, for example, a furring strip or a frame α at a so-called joint position.
From the inside (residential side) and attach the mounting part 4 with bolts,
Alternatively, fix it to the frame α with a screw or the like. In addition,
The receiver B is engaged with the locking claw portion 3 in correspondence with the thickness of the board F, and the backup material C made of polyethylene foam is integrally attached to the mounting surface 10 of the receiver B. Is.

Next, when all the boards F have been installed from inside by metal fittings, a gondola (not shown) is mounted to fill the caulking material E into the joint portion G. This structure eliminates the need for scaffolds at all.

The above description is only one example of the joint structure according to the present invention, and the mounting bracket A can be formed as shown in FIGS. 6 (a) to 6 (e). That is, FIG. 3A shows the locking claw portion 3 recessed into a right angled triangular shape.
Figure (b) shows the shape with ripples in (a),
(C) shows that the locking claw portion 3 is formed only at one deep position, and (d) shows that the lower part of the locking portion 1 is made thinner than the other, and a step is provided, (e). The figure shows a fitting A having a curved top surface 2.

FIGS. 7 (a) to 7 (c) show other modified examples of the receiver B. FIG. 7 (a) shows a button punch β added, and FIG. 7 (b) shows a plurality of wavy shapes. The engaging claws 8 are shown as (c) and (a) and (b).

FIGS. 8 (a) to 8 (e) show a case in which the receiver B and the backup material C are combined to make the construction even easier. To explain further, (a) shows the backup material C.
Makes the surface of the rough surface easy to adhere the caulking material E,
Further, it is a case where the receiving body B and the backup material C are integrated by interposing the jelly-like adhesive 11. Also,
(B) is a case where a sheet material D, for example, lead foil with kraft paper is interposed and integrated on the adhesive surface of the backup material C, and (c) figure is undercoating of the caulking material E on the surface of the backup material C. In the case where the minute E is already attached, (d)
The figure shows a case where the sheet material D is integrally attached to both sides of the backup material C and is integrally formed, and the figure (e) shows that the lower part of the backup material C is highly foamed and the other is a normal foamed body,
This is a case where the sheet material D is integrally attached to the surface thereof. FIG. 9 shows a case where the locking portion 1 of the mounting bracket A is formed as shown.

[0019]

As described above, according to the joint structure according to the present invention, the mounting metal fitting can be mounted on the body from the inside (residential side), and the receiver and the backup material can be integrally mounted, so that the construction is extremely easy. Efficient. The thickness of the board can be easily accommodated because the dimensions can be easily adjusted by engaging the receiving body.
Because it is a backup material that makes it easy to attach caulking material, it can be filled without using scaffolding with a gondola, etc., resulting in significant cost reduction. The combination of a backup material and a sheet can enhance waterproofness, sound insulation and heat insulation. There are characteristics and effects.
