PROBLEM TO BE SOLVED: To provide a floor finishing material, the joint structure of the floor finishing material, and a method of manufacturing the floor finishing material allowing easy construction of a member for adding functionality to the floor finishing material, coping with rooms of various sizes and shape, easily manufactured from a used material and having the appearance of a rich feeling of wood quality. SOLUTION: In this floor material formed by extrusion-molding an extruded material formed of a waste material containing resin, functional members are suitably selected and inserted in a plurality of hollow parts provided inside, to easily manufacture the floor finishing material provided with a desired function. When jointing the floor finishing materials to each other by inserting a projecting part into a groove part, it is constituted to form a clearance between the projecting part and the groove part. The volumetric increase of the floor finishing material caused by the expansion of a resin material by heat can thereby be absorbed. Further, a pattern of streaks is formed on the surface of the floor finishing material, and surface treatment is applied to improve the feeling of wood quality. |
