Description

[Detailed Description of the Invention] The present invention relates to a joint cover (hereinafter simply referred to as a cover) that serves as a decorative and waterproof material for joint parts when inner and outer walls are formed using panels.

In general, walls constructed using panels, such as walls constructed horizontally or vertically, are
A so-called joint is formed where the panel ends face each other, and a waterproof, decorative cover is usually cast over this joint. That is, in conventionally used cover materials, a cover having a width wider than the joint width is laid over the joint, and the cover is fixed to the joint by driving a nail through the top of the cover. As a result, the nail heads are directly exposed on the wall surface, which is a major drawback in terms of waterproofing and aesthetics. Furthermore, Utility Model No. 54-26647 is known as a cover for this item. However, this cover has a vertical end in the width direction, a flat surface in contact with the surface of the exterior wall material, and is fitted into the gassho claw of the fixture, so the fitting part of both parts is If the height relationship deviates, there is a drawback that a large gap is formed at the contact area between the cover and the surface of the exterior wall material. Further, since the cover itself has a substantially rectangular cross section, there is a disadvantage that distortions during molding appear on the decorative surface.

In order to eliminate these drawbacks, the present invention is manufactured by forming a plate material into a trapezoidal longitudinal section by roll forming, extrusion, or drawing, and by providing a gassho claw protruding along the longitudinal direction on the central back surface of the plate material. We propose a cover that can easily absorb errors and installation errors with elasticity and can be installed in close contact with the panel surface at all times.

An embodiment of the cover according to the present invention will be described in detail below with reference to the drawings. That is, the first
Figures a and b are perspective views showing typical examples of the above-mentioned covers, where figure a is a solid one-piece cover formed by extrusion, drawing, or injection molding, and figure b is a two-piece cover formed from a plate material by roll forming. It is a cover with a multilayer structure. To explain in more detail, 1 is a long body made of a material with a thickness that allows the cover to exhibit elasticity, such as a metal plate (color steel plate, PVC steel plate, aluminum plate, stainless steel plate, copper plate, etc.), or a synthetic resin material formed into a predetermined shape. This is what I did. That is, the cover 1 is formed from a decorative surface portion 2 and a palm-to-palm claw 5 extending longitudinally from the center of the back surface of the decorative surface portion 2. The decorative surface section 2 is a long front decorative surface 3.
and a side surface decorative surface 4 whose longitudinal side edges are arranged at an obtuse angle θ inward. This contacts the decorative surface a of the panel (for example, indicated by A in FIG. 2) under line contact, and also applies elasticity to the entire decorative surface portion 2 at all times even in the attached state, so that cover A and cover 1
This is to create a beautiful appearance of the decorative surface portion 2 without creating any voids therebetween. Further, the gassho claw 5 is provided to protrude perpendicularly from the back surface 3a of the front decorative surface 3, and is used to attach the cover itself to a fitting claw to be described later. That is, the gassho claw 5 has a dogleg-shaped side wall 6 disposed symmetrically to form a substantially diamond-shaped fitting groove 7 and a so-called entrance groove 8, which is a narrow gap formed in a portion where the lower ends of the side walls 6 face each other. , the lower end of each side wall 6 is extended, and a guide piece 9 is bent outward, and a guide groove 10 is formed in a V-shape. To explain further, the side wall 6 is thick enough to be elastically deformed enough to fit a fitting claw, which will be described later, and the entrance groove 8 can become a gap into which a fitting claw can be inserted due to the elastic deformation of the side wall 6. be. Further, the height H of the decorative surface portion 2 and the height h ₁ of the gassho claw 5 are approximately the same. The plate thickness t of the decorative surface portion 2 of the cover 1 is preferably thicker than the thickness of the side wall 6.

Next, a construction example will be explained using FIG. 2. First, on the body B, a locking body D having a T-shaped cross section and a diamond-shaped fitting claw C at the tip of the rising part is placed at a pitch corresponding to the length of the panel A, which becomes the so-called joint part E. At the same time, the horizontal surface portion d is fixed via a nail F. Next, the back end of each panel A is placed on the surface of the horizontal surface part d, and this part is hit with a nail F to fix each panel A. Next, the engagement claw 5 of the cover 1 is fitted into the fitting claw C of the locking body D, and the cover 1 is attached to the joint E as shown in FIG.

What has been described above is only one embodiment of the cover according to the present invention, and the cover can also be formed as shown in FIGS. 3a to 3i. In other words, figure a shows the side decorative surface 4.
A cover formed in a dogleg shape, figure b shows the front decorative surface 3
a cover in which a rib 3b is formed by protruding the center of the cover;
Figure c shows a cover with the lower end of the side decorative surface 4 extended horizontally and bent upward from the middle, and figure e shows a guide piece 9.
Figure f shows a cover with a slightly longer length from the back surface 3a of the front decorative surface to the top of the fitting groove 7, and Figure g shows a cover with a concave groove 3c in the center of the front decorative surface 3.
Figures h and i show covers with partially thickened parts formed by drawing out or the like. Further, for example, the front decorative surface of the cover may be embossed or coated with lysine. Of course, in order to connect the cover, a part of the gassho claw at one end can be cut off.

As described above, in the cover according to the present invention, the decorative surface portion is formed in a trapezoidal cross section so that the panel surface and the lower end of the side decorative surface are always in contact with each other under a certain elasticity, thereby improving the waterproofness of the joint portion. It has improved features.
In addition, since the cover is always supported under elasticity, no distortion or cracking will appear on the front decorative surface, resulting in a beautiful appearance. Furthermore, the guide groove allows the device to be installed very easily, and after installation, the device is reliably attached to the fitting claw due to its elasticity.
