DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, specific preferred embodiments of the present invention will be described in detail with reference to the drawings. However, the present invention is not limited to the illustrated embodiments, and various variations are conceivable.
[0006]
The parting material A according to the present invention is formed into a long shape having an appropriate length using an ordinary resin extrusion molding machine or multilayer extrusion molding machine using a thermoplastic resin having flexibility, On the front side, a desired design such as a design pattern by printing, a drawn pattern by molding, or a design by shape is applied as appropriate, and the waist wall sheet or the building surface pasted from the ceiling side to the floor surface B of the building wall It is disposed at a parting end D ′ of a floor sheet (hereinafter simply referred to as a sheet) D raised from the floor surface B along the wall surface C, and is attached to the wall surface B with an adhesive. Moreover, if a multilayer extrusion molding machine is used, the parting material A of 2 or more types of resin or a combination of 2 or more colors can be formed.
By the way, FIG. 2 shows an example of a floor sheet raised from the floor B of the building along the wall surface C as the sheet D to be applied, the symbol E in the figure indicates the same or different kind of floor material as the sheet D, Reference numeral F denotes a welding mark obtained by welding the sheet D and the floor material E.
[0007]
The parting material A is formed in an elongated shape having a cross-sectional shape substantially the same radius as the thickness L1 of the parting end portion D ′ of the sheet D and the lower end surface 1 is a flat, substantially quadrangular shape, and its upper edge A press-contact edge 2 having a substantially bowl-shaped cross section that is urged into contact with the wall surface C is extended over the entire length of the parting material A, and a lower edge is provided on the back surface D1 ′ of the parting end D ′ of the sheet D. The leading adhesive edge 3 is extended over the entire length of the parting material A.
Although the thickness L2 of the parting material A is set according to the thickness L1 of the sheet D, when the parting material A is joined to the parting end D ′ of the sheet D as in the illustrated embodiment, It is preferable to form such a thickness that D ′ does not protrude from the lower end surface 1 of the parting material A. The width L3 of the parting material A is not particularly limited, but is 1 mm to 15 mm, preferably 2 mm to 10 mm.
[0008]
The press-contact edge 2 is used to absorb the unevenness even when the wall surface C is somewhat uneven, so that no gap is generated between the rear surface side of the upper edge of the parting material A and the wall surface C. In addition, it is formed in a substantially bowl-shaped cross-section with a sharp bend like a ridge so that it comes into urging contact with the wall surface C, and the tip side 2 'of the parting material A is directed toward the wall surface C. (Adhesion surface) 4 is formed so as to protrude slightly.
[0009]
Further, the adhesive edge 3 extending to the lower edge of the parting material A is for bonding the parting material A more firmly when joining the parting end D ′ of the sheet D. To the lower side from the end surface 1, when the parting end portion D ′ of the sheet D is brought into contact with the lower end surface 1 of the parting material A, the length D4 reaches the back surface D1 ′ of the parting end portion D ′. It is formed by hanging in a shape.
[0010]
The synthetic resin for forming the parting material A is not particularly limited as long as it is a thermoplastic resin that is bonded to the sheet D by thermal welding or solvent welding and has flexibility, and specifically, a vinyl chloride resin. , Halogen-containing resins such as chlorinated polyethylene, polyethylene, polypropylene, ethylene-α olefin copolymer resin, propylene-α olefin copolymer resin, ethylene-vinyl acetate copolymer resin, ethylene-acrylic acid ester copolymer resin, ethylene-methacrylic resin Olefin resins such as acid ester copolymer resins, ethylene-acrylic acid copolymer resins, olefin thermoplastic elastomers, styrene thermoplastic elastomers, polyester thermoplastic elastomers, thermoplastic elastomers such as urethane thermoplastic elastomers, etc. Can be mentioned.
[0011]
Thus, in the case of performing the construction in which the parting material A is installed on the wall surface C, the lower end surface 1 and the bonding edge 3 of the parting material A are preliminarily welded or solvented to the parting end portion D ′ of the sheet D. The parts A are joined together by welding, and then the parting material A is adhered to the wall C together with the sheet D with an adhesive.
As the adhesive used here, a well-known double-sided adhesive (adhesive) tape or a liquid adhesive such as rubber, epoxy, urethane, vinyl acetate, and acrylic can be suitably used.
[0012]
Next, specific examples will be described.
<Example 1>
As a thermoplastic resin, soft polyvinyl chloride (PVC) having the following composition was used, and a parting material A shown in FIG.

Tetrahydrofuran is used as the solvent, and the molded parting material A is solvent-welded to the parting end D ′ of the polyvinyl chloride waist wall sheet D having a thickness of 3 mm. Thereafter, as shown in FIG. Affixed to the wall surface C together, the parting material A and the waist wall sheet D had a sense of unity, and finished with no gap between the wall surface and the wall.
[0013]
