Detailed Description of the Invention

[0001]

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

[0002]

2. Description of the Related Art As is well known, various long decorative members, for example, curtain boards, head boards, gable boards, nose cover boards, window decorations, etc., are attached to the exterior of buildings such as wooden houses. When mounting these decorative members, it is necessary to take into account the heat contraction of the decorative members themselves, that is, the thermal expansion and contraction of the decorative members themselves, that is, the structure of the connecting portion between the decorative members. Especially when the decorative members are long enough or made of a resin material having a relatively large coefficient of thermal expansion, the amount of thermal contraction also becomes large, so some measures must be taken at the connecting part. Is.

Therefore, in the past, various measures have been taken. For example, in Japanese Patent No. 2587161, as shown in FIG. 1 and FIG. 2, the end portions of the curtain plates (decorative members) 1 and 2 to be connected are secured to each other while securing a certain gap therebetween. They are butted against each other in such a manner that they can be displaced relative to each other, and the butted portions are joined to both curtain plates 1,
It is described as being covered with a cover 3 that spans the ends of 2. The cover 3 is fixed to one of the two curtain plates 1 and 2 to be connected, and is not fixed to the other side, in order to allow thermal deformation of the curtain plate. Further, a deformable sealing material 4 such as silicone is filled in the gap between the end portions of the curtain plates 1 and 2 in order to ensure a sealing property so that rainwater and the like do not enter. Further, as shown in FIG. 4, the one in which the joint metal fitting 8 is interposed inside the abutting portions of the end portions of the curtain plates 6 and 7 to be connected is also generally known.

[0004]

However, the above-mentioned conventional technique has the following drawbacks. That is, in the former case shown in FIG. 1 and FIG. 2, when the end portions of the curtain plates 1 and 2 receive a force in a direction in which they approach each other, as shown by the white arrow in FIG. The phenomenon of swelling occurs. At this time, since the cover 3 is fixed to the curtain plate 1 only on one side, if it is pushed up from the inside by the sealing material 4, as shown in FIG. 3, it obliquely projects and rainwater or the like easily enters. Alternatively, there is a drawback that the appearance is impaired.

Further, in the latter one shown in FIG. 4,
If the joint fitting 8 is first fixed to the base material 9 or the like, the curtain plates 6 and 7 may not be attached later. In other words, the joint metal fittings 8 must first be assembled inside the curtain plates 6 and 7 and attached to a base material or the like, and there is a drawback that the degree of freedom in construction is low. When the joint metal fitting 8 is fixed first, the curtain plates 6 and 7 cannot be assembled afterwards because the undercut portion for fitting is usually provided above the curtain plates 6 and 7 as shown in FIG. 10 is provided, and in order to engage this with the engaged portion 8a of the joint metal fitting 8, the joint metal fitting 8 must be slid from the lateral direction, not from the rear side, and fitted. This is because if the space for sliding the curtain plates 6 and 7 to the side of the curtain plates 6 and 7 is not secured, the fitting of the curtain plates 6 and 7 themselves to the joint fitting 8 cannot be performed. Also,
In the connection structure of the curtain plates shown in FIG. 4, when the curtain plates 6 and 7 are thermally contracted, the gap between the end portions of the curtain plates 6 and 7 becomes wide,
There was also the drawback that the joints would be visible.

According to the present invention, the cover member does not come off, a good sealing property of the connecting portion can be ensured, the flexibility of construction is high, and the joint portion is conspicuous even when there is a large temperature change. It is an object of the present invention to provide a structure for connecting decorative members that is superior in design.

[0007]

To achieve this object, the connecting structure for decorative members of the invention according to the first aspect is a structure for connecting the end portions of the decorative members to each other. The edge cover of the decorative member is made of a material having elasticity so that the edge surface covers the edge surface.
And has a clearance between the small edge covers
A joint cover is provided so as to straddle the end portions of both the decorative members to which the small edge covers are attached, and the joint cover is fixed to one of the decorative members and to the other decorative member. Is provided so as to be movable relative to each other, the fore edge cover is similar to the shape of the fore edge surface of the decorative member and is set larger than the fore edge surface, and its end in a state of being attached to the fore edge surface.
