<p>PROBLEM TO BE SOLVED: To improve workability by respectively fastening/installing a horizontal part piece, a vertival part piece having the bending part on one side and a footboard to/on a column, and installing a reinforcing piece between both part pieces. SOLUTION: A footboard support metal fitting A for stairs is composed of a metal fitting main body 1 and a reinforcing piece 2, the metal fitting 1 is formed in an L-shape out of a horizontal part piece 3 and a vertical part piece 4, and a bending part piece 5 is arranged in an orthogonal shape on one side of the part piece 4. Next, the reinforcing piece 2 is pivotally fixed to the part piece 3 by inserting a grommet 9 into a tip side long hole 6a of the part piece 3 and a through hole 8a of an installing part piece 7 arranged in the end part of the reinforcing piece 2. The metal fitting 1 is fixed by a fastening installing lever 12a by adjusting a vertical position after being temporarily fastened by the fastening installing lever 12a through an adjusting hole 11b by engaging the corner part formed of the part pieces 4, 5 with the corner part of a column P. Next, a fastening installing lever 12b inserted into the grommet 9 is fixed to a footboard S by fixing a superposing part piece 10 and the part piece 4 to the column P by the fastening installing lever 12a by rotating the reinforcing piece 2 with the grommet 9 as the center after being fixed by the fastening installing lever 12b by placing the footboard S on the part piece 3. Therefore, efficiency can be improved by easily performing positioning.</p> |
