Claims

[Claims for Utility Model Registration] (1) A structure that connects the ends of adjacent scaffolding boards, the first and second engagement shafts provided on one scaffolding board and the second engagement shaft provided on the other scaffolding board. The first and second engagement shafts and the first and second elongated holes are respectively formed in the side wall of the end of the scaffold board in the width direction of the scaffold board. The first engagement shafts are provided at intervals, and include a vertical axis protruding from the side wall of the scaffold board, and a horizontal axis extending in the thickness direction of the scaffold board at a location of the vertical axis having a protruding length corresponding to the thickness of the side wall. The second engagement shaft has a vertical axis that projects from the side wall of the scaffold board, and a horizontal axis that extends in the width direction of the scaffold board at a location on the vertical axis with a protruding length corresponding to the thickness of the side wall. The first elongated hole is formed in a side wall at the end of the scaffolding board in a shape corresponding to the horizontal axis of the first engagement shaft and is oriented approximately 90 degrees out of alignment; 2 elongated holes are provided in the side wall at the end of the scaffold board.
A connecting structure for scaffolding boards, characterized in that the connecting structure is formed to extend in an open manner from the lower end of a side wall with a width corresponding to the outer diameter of a vertical axis of an engagement shaft. (2) A structure that connects the ends of adjacent scaffolding boards, with a first elongated hole and a second engagement shaft provided in one scaffolding board, and a first engagement shaft provided in the other scaffolding board. The first long hole and the second engaging shaft, and the first engaging shaft and the second long hole are formed on the side wall of the end of the scaffold board, respectively. The first engagement shaft has a vertical axis protruding from the side wall of the scaffold board, and extends in the thickness direction of the scaffold board at a location of the vertical axis with a protruding length corresponding to the thickness of the side wall. The second engagement shaft has a vertical axis that projects from the side wall of the scaffold board, and a vertical axis that extends in the width direction of the scaffold board at a location on the vertical axis with a protruding length corresponding to the thickness of the side wall. the first elongated hole is formed in a side wall at an end of the scaffolding board in a shape corresponding to the horizontal axis of the first engagement shaft and whose orientation is shifted by approximately 90 degrees; The second elongated hole is formed in the side wall of the end of the scaffold board.
A connecting structure for scaffolding boards, characterized in that the connecting structure is formed to extend in an open manner from the lower end of a side wall with a width corresponding to the outer diameter of a vertical axis of an engagement shaft. (3) The scaffold board connection structure according to claim 1 or 2, wherein the first and second engagement shafts are arranged so as to be retractable from a side wall at an end of the scaffold board.
