Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention is used in the technical field of attaching board materials such as exterior boards for architecture and structures.

(Prior Art) In conventional buildings or structures, as shown in FIG.
To maintain the board gap b constant, use a hat-shaped joint member c made of galvanized steel plate, etc.
A commonly used construction method is to fill the joints between the boards with caulking material d to form joints.
Therefore, the chevron portion f of the hat-shaped joint member c
The caulking material d adheres to the surface of. However, exterior boards a and a repeatedly expand and contract under the influence of changes in outside temperature and sunlight, and tensile and compressive forces are constantly applied to caulking material d, causing cracks in caulking material d over time. There is a problem in that the durability is reduced due to the occurrence of rainwater and the like.

(Purpose of the invention) An object of the invention is to provide a structure for connecting an exterior material to prevent the caulking material from cracking as described above.

(Structure of the invention) The means for achieving the above object is to make the end surfaces of exterior materials such as boards for buildings and structures face each other, interpose the chevron-shaped portion of a hat-shaped joint member between the end surfaces of the boards, and At the joint where the gap between the end faces is filled with caulking material, the surface of the chevron part of the hat-shaped joint member is coated with polyethylene or other non-adhesive resin, and the coating of polyethylene or other non-adhesive resin is combined with the caulking material. This is a connection structure for exterior materials such as boards of a building, which is characterized by preventing adhesion.

The effect of the present invention is that the caulking material filled in the gap between the end faces of the exterior material board by the above method does not adhere to the chevron part of the hat-shaped joint member, so that it is prevented from expanding or contracting due to temperature changes of the exterior material board. This allows the caulking material to expand and contract uniformly, thereby preventing the occurrence of cracks in the caulking material.

(Example) Hereinafter, an example of the connection part structure of the exterior material such as a board of the structure of the present invention will be described based on the drawings.

Fig. 1 shows a front view of a part of a building to which the present invention is applied, Fig. 2 shows a cross-sectional view of the connection structure between the exterior material board and the above-mentioned hat-shaped joint member, and Fig. 3 shows the structure of the connection part between the exterior material board and the above-mentioned hat-shaped joint member. A part of the member is shown in a perspective view.

F is a part of the building and W is a window. The hat-shaped joint member 1 is formed by molding a steel plate 2 with a thickness of about 0.2 mm to 0.8 mm into a hat shape, and the surface of the steel plate 2 is coated with a non-adhesive resin such as polyethylene resin or other polyphenylene sulfide resin. 3 is 0.3mm
The edge parts 5a, 5a of the sleeve parts 5, 5 on both sides of the central chevron part 4 are folded upward, and screw holes 1 are formed at appropriate positions in the sleeve parts 5, 5.
a and 1a are provided.

To explain the connection structure of exterior materials such as boards of the structure of the present invention, asphalt felt or other sheet material 9 is brought into contact with the pillar of the structure, and this sheet material 9 is
The joint member 1 is brought into contact with the joint member 1 and the screw 10 is tightened. Next, the end surfaces 6a, 6b of the exterior material board 6 are attached to the side walls 4c, 4d of the chevron portion 4 of the joint member 1.
The exterior material board 6 is fixed by abutting on it. Next, a caulking material 7 such as acrylic resin or urethane resin is filled into the gap where the end surfaces 6a and 6b of the exterior material boards 6 and 6 face each other.

Since the surface of the chevron portion 4 of the joint member 1 is coated with a non-adhesive polyethylene resin or the like, the caulking material 7 is not adhered and a slight gap 11 is created.

In the embodiment described above, the coating 3 of the non-adhesive resin is applied to almost the entire upper surface of the joint member 1, but the coating may be applied only to the upper surface of the chevron portion 4.

The standard dimensions of the hat-shaped joint member 1 are shown below.

The height of the chevron part is approximately 5 mm, the width of the chevron part is approximately 8 mm, the width of each sleeve part is 20 mm, and the total length of the hat-shaped joint member is approximately 3030 mm.The above dimensions may be different depending on the size of the building or structure.

(Effect of the invention) According to the structure of the board connection part of the structure of the present invention, a chevron-shaped part of a hat-shaped joint member is interposed between the end faces of the opposing boards, and the top face is coated with a non-adhesive resin. Because of this, the caulking material that fills the gaps between the board edges adheres to the board edges but does not adhere to the chevrons of the joint members, so even if the temperature of the board changes, a uniform expansion and contraction force will act upon it when it expands and contracts. This has the excellent effect of preventing the occurrence of cracks.
