[0002]

2. Description of the Related Art Conventionally, a synthetic resin skirting board is often used in the lower part of a wall of a building or a corridor. These skirting boards are generally in the form of a long sheet having a width (height) of 50 to 200 mm, and one end of the sheet in the width direction (lower end portion) is R (velocity) so as to hide the end of the floor material. ) Is provided. Usually, synthetic resin skirting boards and flooring materials are not welded, but when waterproofness or antibacterial properties are required, for example, in hospitals, nursing homes and other welfare facilities or washrooms, this R part The terminal portion and a synthetic resin floor material laid on the floor are welded.

[0003]

When the above-mentioned conventional skirting board is welded to the synthetic resin flooring material, the welding work is difficult and requires skill because the R portion of the lower end portion of the skirting board is short. In addition, since it is a welding work near the wall, it is difficult to cut the protruding portion of the welding rod smoothly after welding so that it is at the same level as the floor material. It became convex, and dust and dirt were likely to collect between the flooring and the skirting board, which was not an aesthetically pleasing and hygienic finish. Further, if there is unevenness (unevenness) on the floor surface, there is a problem that the welded portion of the floor material and the baseboard meanders.
