Description of the Related Art Conventionally, temporary scaffolds constructed when constructing bridges, highways, and the like have to be constructed on the ground beforehand in order to reduce work in high places and to perform safely and efficiently. The blocks, which are laid in the form of a figure, are transported to a construction site while being lifted with a crane or the like, and are sequentially stacked upward to be constructed.

[0003] Incidentally, such a terrain block for constructing a temporary scaffold is generally constructed by assembling columns in a rectangular shape with horizontal connecting members, and this will be described with reference to FIG. That is, in the figure, reference numeral 51 denotes a strut having a two-layer height constituting the ground block A.
Are integrally formed by a metal pipe material. Reference numeral 52 denotes a mounting flange having a required number of engaging holes (not shown) fixed to the column 51 at predetermined intervals, 53 denotes a connection pipe of a required length formed at the upper end of the column 51, and 54 denotes a lower end of the column 51. The connecting pipe 53 has an outer diameter that allows the connecting pipe 53 to be inserted into the connecting hole 54. Reference numeral 55 denotes a horizontal connecting member made of a metal pipe having a pair of connecting fittings 56 fixed to both ends thereof, and 57 denotes an engaging hole (not shown) of the mounting flange 52 through which the connecting fitting 56 is inserted.
It is a wedge that can be press-fitted. Numeral 58 denotes a ground reference base formed by connecting a required number of short struts 60 with jacks provided with mounting flanges 59 having engaging holes (not shown) by wedge connecting means by horizontal connecting members 55. .

When assembling the terrain block A for constructing a temporary scaffold, the column 51 is erected through the connection hole 54 in the terrain reference base 58, and the upper end of the column 51 adjacent to the column 51 is formed. The horizontal connecting members 55 are sequentially connected to the intermediate portion by the wedges 57 via the mounting flange 52 and the connecting metal fittings 56, and assembled into a rectangular block shape. Thereafter, the truss block A is transferred to a required construction site via a crane (not shown), and is connected to the connecting pipe 53 of each of the stanchions 51 constituting the previously stacked truss block A. The connecting holes 54 at the lower ends are sequentially stacked upward while being inserted, thereby constructing a temporary scaffold having a required height.
