DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a connecting structure suitably used for connecting various decorative members attached to an outer wall of a wooden house or the like.

[0002]

2. Description of the Related Art As is well known, a building such as a wooden house is provided with various long decorative members, for example, a curtain plate, a cap, a gable board, a blindfold, a window decoration, and the like. In mounting these decorative members, it is necessary to take into account the thermal contraction of the decorative members themselves, that is, the thermal expansion and thermal contraction caused by a change in the outside air temperature, particularly in the structure of the connecting portion between the decorative members. In particular, when such decorative members are sufficiently long or made of a resin material having a relatively large coefficient of thermal expansion, the amount of thermal shrinkage increases, so some measures must be taken at the connection part. It is.

For this reason, various devices have hitherto been devised. For example, in Japanese Patent No. 2587161, as shown in FIG. 1 and FIG. 2, the end portions of curtain plates (decorative members) 1 and 2 to be connected are secured while securing a certain gap between them. Butts in a state that they can be relatively displaced in a direction of coming and going with each other, and the butting portion is joined to both curtain plates 1,
2 is covered with a cover 3 that straddles the end of FIG. Note that the cover 3 is fixed to one of the two curtain plates 1 and 2 to be connected and not fixed to the other side to allow thermal deformation of the curtain plate. In addition, a gap between the end portions of the curtain plates 1 and 2 is filled with a deformable sealing material 4 such as silicone in order to secure a sealing property so that rainwater or the like does not enter. In addition, as shown in FIG. 4, one in which a joint fitting 8 is interposed between the ends of the end portions of the curtain plates 6 and 7 to be connected is also conventionally known.

[0004]

However, the above-mentioned prior art has the following drawbacks. That is, in the former shown in FIGS. 1 and 2, when the ends of the curtain plates 1 and 2 receive a force in the direction of approaching each other, the sealing material 4 is moved outward as shown by a white arrow in FIG. Swelling phenomenon occurs. At this time, since the cover 3 is fixed to the curtain plate 1 on only one side, when the cover 3 is pushed up from the inside by the sealing material 4, as shown in FIG. Alternatively, there is a disadvantage that the appearance is impaired.

[0005] In the latter case shown in FIG.
If the joint fitting 8 is fixed to the base material 9 or the like first, the curtain plates 6 and 7 may not be attached later. That is, it is necessary to attach the joint fitting 8 to the base material or the like in a state where the joint fitting 8 is previously assembled inside the curtain plates 6 and 7, and there is a disadvantage that the degree of freedom of construction is low. It should be noted that, when the joint fitting 8 is fixed first, the curtain plates 6 and 7 cannot be assembled later, as shown in FIG. In order to engage the joint 10 with the engaged portion 8a of the joint fitting 8, it is necessary to slide the joint fitting 8 not from the rear side but from the lateral direction to fit. If there is not enough space to slide the curtain plates 6 and 7 to the side of the curtain plates 6 and 7, the curtain plates 6 and 7 themselves cannot be fitted to the joint fittings 8. Also,
In the connection structure of the curtain plates shown in FIG. 4, when the curtain plates 6 and 7 are thermally contracted, the gaps between the ends of the curtain plates 6 and 7 are widened,
There was also a drawback that the joints were eyes.

According to the present invention, a good sealing property of the connecting portion can be ensured without detaching the cover member, and the degree of freedom of construction is high, and the joints are visible even when a large temperature change occurs. It is an object of the present invention to provide a connection structure for decorative members that is excellent in design.

[0007]

In order to achieve this object, a connecting structure for a decorative member according to the first aspect of the present invention is a structure for connecting the ends of the decorative member. A fore cover is attached to the fore face of the decorative member so as to cover the fore face, respectively, and a joint cover is provided so as to straddle the ends of the two decorative members to which the fore covers are attached. It is characterized in that it is fixed to one decorative member and is provided so as to be relatively movable with respect to the other decorative member. The joint structure of the decorative member according to claim 2 is characterized in that convex portions are provided on both side ends of the inner surface of the joint cover, and the convex portions are in contact with the outer surface of the decorative member. And In the connecting structure of the decorative member according to the third aspect of the present invention, the fore cover is set to be larger than the fore-face of the decorative member, and the end of the fore-cover is attached to the fore-edge surface so as to protrude outward. The overhang is in contact with the inner surface of the joint cover. According to a fourth aspect of the present invention, the drainage hole is formed at a lower portion of the joint cover.
In the connecting structure of the decorative member according to the fifth aspect of the present invention, among the convex portions provided at both end portions of the inner surface of the joint cover, the convex portion corresponding to the fixed decorative member is formed of a double-sided tape. It is characterized by being.
