Description

The present invention relates to a plate material cover that covers both abutting portions of a pair of skirting boards or plate materials such as peripheral edges arranged on both sides of the wall surface near the floor or the ceiling along the wall surface.

In the building, a skirting board is provided near the floor of the wall surface, and a peripheral edge is provided near the ceiling of the wall surface. Board materials such as skirting boards or peripheral edges improve the appearance of the wall surface and protect the wall surface. Since this plate material is formed in a straight line, the abutting portion of the pair of plate materials abutted by the wall surface such as the outside corner and the inside corner creates a gap between the abutting surfaces (kiguchi). The plate material cover covers the abutting portions of both of the above-mentioned pair of plate materials and hides the above-mentioned gap.

The plate material cover described in Patent Document 1 has a surface coating portion that covers the plate material and extends to the back surface side of the surface coating portion by arranging the tip portions facing each other on the ceiling or the floor, and is formed between the back surface and the wall surface of the plate material. By arranging it between them, it extends along the vertical direction so as to partition the butt end faces of both the plate-shaped blade portion that sandwiches the plate material together with the surface covering portion and the pair of plate materials, and is joined to the blade portion. It is provided with a blade support portion that supports the blade portion. Further, the surface covering portion is formed with an engaging convex portion that engages with the concave groove formed in the longitudinal direction of the surface of the plate material, and the joint portion between the blade portion and the blade supporting portion engages in the vertical direction. It is designed to be on the tip side of the convex part. As a result, when the plate material cover is attached to both abutment portions of the pair of plate materials, the plate material is sandwiched between the surface covering portion and the blade portion, so that the horizontal movement of the plate material cover can be restrained. Further, since the concave groove formed on the surface of the plate material and the engaging convex portion formed on the surface covering portion engage with each other, the vertical movement of the plate material cover can be restrained. Therefore, it is possible to prevent the plate material cover from falling off from the plate material without using double-sided tape or an adhesive for fixing the plate material cover to the plate material.

Further, in the plate material cover described in Patent Document 1, the joint portion between the blade portion and the blade support portion supporting the blade portion is located on the tip end side of the engaging convex portion in the vertical direction, and the engaging convex portion is provided. There is no joint portion of the blade portion joined to the blade support portion at the position facing the blade portion. As a result, when the plate material cover is attached to the plate material from the vertical direction, even if the engaging convex portion formed on the surface covering portion rides on the surface of the plate material before engaging with the concave groove of the plate material, it engages. Since the blade portion does not exist at the position facing the convex portion, the surface coating portion and the blade portion are not damaged due to the action of excessive force, and the plate material cover can be smoothly arranged at the corner of the wall.
