PROBLEM TO BE SOLVED: To improve finished appearance, enhancing workability largely, and to increase the mounting strength of a building material. SOLUTION: An inserting connecting piece 1 is projected from one side section in the cross direction of a long-sized building material body while an inserting recessed section 2 is formed to the other side section in a folded-back shape. The rear piece of the recessed section 2 is extended outwards, and the building material is constituted as a fixing piece 3. The fixing piece 3 of the building material A disposed in the direction crossed at approximately right angles with the supporting sash bars 4, 4 fixed at an interval is fixed onto the supporting sash bars 4. The inserting connecting piece 1 of the adjacent building material A is inserted and connected to the inserting recessed section 2 in the execution structure of the building materials. Approximately L-shaped pawls 6 are formed to the supporting sash bars 4 in response to the execution pitches of the building materials A, and the bottom-section external surfaces of the inserting recessed sections 2 are abutted and held to the internal surfaces of the pawls 6 and the building materials A are positioned. |
