PROBLEM TO BE SOLVED: To raise efficiency of dismantling a construction scaffold board by allowing it to be simply removed by one-man operation. SOLUTION: The opening on the lower part of a recess 3 on a clamp metal fitting 2 on at least one side of a scaffold board body 1 is to have enough area so that the scaffold board body 1 can be drawn out from the standard horizontal member P with the scaffold board body 1 tilted. An abutment projection 12 making the standard horizontal member P abut on the fringe 5 on the recess 3 side of a lock metal fitting 4 is protrusively formed toward the recess 3. It is contrived so that the abutment projection 12 abuts on standard horizontal member P, when the scaffold board body 1 is pushed down to the standard horizontal member P side in a tilted condition, and the lock metal fitting 4 is unlocked by rotationally moving anticlockwise with the abutment projection 12 as a fulcrum. Thus by pushing down the scaffold board along the tilted direction with holding of the clamp metal fitting 2 on one end of the scaffold board is unlocked and lifted up, holding of the lock metal fitting 4 on the clamp metal fitting 2 on the other end side can be unlocked without touching it so the scaffold board can be removed by a single person.
