Claims (1)

[Scope of Claim for Utility Model Registration] (1) A column erected vertically from the foundation, and a long column that runs perpendicular to the column in the horizontal direction and is fixed so as to sandwich the column from both sides. In a construction scaffolding board placed on the tubular scaffolding member in a scaffolding assembly structure comprising a tubular scaffolding member; a construction scaffold board formed protrudingly extending in the longitudinal direction approximately at the center in the width direction of the lower surface of the main body of the scaffolding board; A scaffold board for construction work, further comprising a positioning member that is locked to the tubular scaffold member and whose movement in the width direction is restricted. (2) The positioning member includes a band-shaped fixed piece fixed to the widthwise center of the lower surface of the scaffold board, and both ends of this fixed piece are bent downward, and a circular piece is formed approximately corresponding to the outer circumferential shape of the tubular scaffold member. 2. The scaffolding board for construction work according to claim 1, comprising an elastic piece formed into an arc shape. (3) The positioning member consists of a pair of horseshoe-shaped positioning members on both sides of the lower surface of the scaffold board body in the width direction and corresponding to the tubular scaffolding member, and is fixed so that the separated portions of the horseshoe-shaped positioning members face downward. 2. The construction scaffold board according to claim 1, wherein the tip thereof is a guide portion bent outward to guide the tubular scaffold member. (4) At approximately the center in the width direction of the scaffold board main body, a positioning member consisting of a protrusion that projects in parallel along the opposing gap between the tubular scaffold members in the extending direction of the main body is provided, and 2. The construction scaffolding board according to claim 1, wherein the positioning member is integrally formed. (5) A dovetail groove is formed at the center of the lower surface of the scaffold board body, a dovetail is formed on the upper surface of the positioning member, and the dovetail is engaged with the dovetail groove to form a dovetail groove at the center of the lower surface of the main body and the gap between the tubular scaffold members. 2. The construction scaffold board according to claim 1, wherein a positioning member is fixed to the construction scaffold board. (6) The construction scaffold board according to claim 5, wherein the side wall of the positioning member is formed in a shape corresponding to the outer peripheral surface of the tubular scaffold member.
