PROBLEM TO BE SOLVED: To provide a fixing method of a base material to a wall surface with which the base material can be firmly, easily and surely mounted even when the wall surface is made of a weak material such as a gypsum board, and a Nageshi (a horizontal piece of timber to connect pillars) rail as furniture for improving the appearance.SOLUTION: A base material 1 to be a foundation of mounting to a wall surface W is formed in a band plate shape by extrusion molding of aluminum or the like, a ridged inflection rib 7 formed from an upper inclined wall 7a and a lower inclined wall 7b is provided thereon in a projective manner and on an inner surface of the upper inclined wall, an inner protrusion 13 is provided in a projective manner in parallel with the lower inclined wall, thereby providing an inclined narrow groove 20 to be a guide for passing a pin between the lower inclined wall and the inner protrusion. On the upper inclined wall, a pair of right and left pin holes 17 are opened for passing the pin along the inclination of the inclined narrow groove. In mounting to the wall surface, the pin is put through the pair of right and left pin holes into the wall surface in a V-shaped pin inclination which is downward inclination and closes a gap between the pair of right and left pin holes, or fan-shaped pin inclination which opens the gap, such that the base material is fixed by the pin. |
