プ３′に据付けても良いこと勿論である。 Note that the reinforcing tool 13 is not necessarily necessary for installing the scaffolding board 5, but if the reinforcing tool 13 is provided, it will prevent the fasteners 6, 6' from shifting upward and downward, and will prevent the fasteners 6, 6' from shifting upward and downward. Since the distance in the vertical direction is kept constant, it is possible to obtain the advantage that the scaffolding board 5 does not wobble. Further, although the board joint 23 is not necessarily necessary to install the scaffolding boards 5, if the scaffolding boards 5, 5 are connected together, the force applied to each scaffolding board 5 will be dispersed, and the scaffolding boards 5, 5 will be the same. Since the scaffold board 5 is kept on a flat surface, it is possible to obtain the advantage that the worker can easily walk on the scaffold board 5. Furthermore, in order to install the scaffolding board 5, an intermediate stopper 2 is used instead of the vise 26 as the installation tool 7.
It is safer to install the scaffolding board 5 on the horizontal pipe 3 using the screws 0 because the lateral movement of the scaffolding board 5 can be restricted by inserting the intermediate stoppers 20 into the holes 18, 18'. Of course, the scaffolding board 5 may be installed not only on the horizontal pipe 3 but also on the horizontal pipe 3'.
