Reference numeral 17 denotes a short-length metal pipe branching support that is fitted and hung on the tenon 4 via a locking pin (not shown). Reference numeral 18 denotes a member formed on the upper outer peripheral surface of the branching support 17. In the combined box body 18, two pairs of upper box members 19 and lower box members 20 are alternately formed radially at a predetermined interval. The length of the branch post 17 is such that when the bracket 1a is attached to the lower box member 16 of the lower engaging box body 12 of the post 10, the upper and lower box members 19 and 20 of the engaging box body 18 are attached. Are set to required lengths so as to correspond to the upper and lower box members 13 and 15 of the upper engagement box body 11, respectively. Reference numeral 21 denotes a jack base of the column 10, reference numeral 22 denotes a bracket with wedges, reference numeral 23 denotes a handrail with wedges, reference numeral 24 denotes an outer wall surface of a building or the like, and reference numeral 25 denotes a projecting portion on the outer wall surface 24.

In order to construct a temporary scaffold along the outer wall 24 of a building or the like having a projecting portion 25 according to the conventional example constructed as described above, first, as shown in FIG. The columns 10 having the jack bases 21 attached thereto are arranged in two rows at predetermined intervals along the outer wall surface 24, and the columns 10 adjacent to each other in the left and right direction (the direction along the outer wall surface 24) of each row are handrailed. (Not shown), and the columns 10 adjacent to each other in the front-rear direction (a direction perpendicular to the outer wall surface 24) are connected by the bracket 22. When approaching the lower end of the projecting portion 25, the wedge 3 is engaged with the lower box member 16 constituting the lower box body 12 of the rear support 10, so that the projecting bracket 1 a is attached, and the branch post 17 is attached to the tenon 4. Are fitted, and are erected by a hook pin (not shown). At this time, the upper and lower step box members 19 and 20 constituting the engagement box body 18 of the branching support 17 are

Are positioned at the same level as the upper and lower box members 13 and 15 of the corresponding upper engagement box body 11, and the handrail 23
Can be easily attached. However, as shown in FIG. 8, when the direction of the column 10 is different, the overhang bracket 1a must be attached to the upper box member 14 of the lower engagement box body 12 with the wedge 3, and as a result, The branching posts 17 inevitably protrude upward according to the height of the box member 14. For this reason, the lower box member 20 of the branching column 17 cannot be made to correspond to the lower box member 15 of the upper engaging box body 11 in the column 10, which hinders the assembly of the temporary scaffold, and is extremely convenient. Was bad.

As a solution to the problem of the prior art, as shown in FIGS. 9 and 10, a height adjusting collar 26 having the same length as the upper box members 13 and 14 is fitted to the tenon 4 as appropriate. Has been proposed an overhang bracket 1b provided with a chain 27 interposed therebetween. The other configuration is the same as that of the above-described conventional example, and the same reference numerals indicate the same parts.

They are positioned at the same level (see FIG. 9). Conversely, when the overhanging bracket 1b is engaged with the upper box member 14 of the lower engaging box body 12 of the support column 10 and mounted, the branch bracket 1b is directly branched to the tenon 4 without fitting the height adjusting collar 26. The pillars 17 are fitted and erected, and the corresponding upper and lower box members 13, 15, 19, and 20 are positioned at the same level (see FIG. 10).

By the way, in the conventional example constructed as described above, the height of the branching post 17 is appropriately adjusted via the height adjusting collar 26 irrespective of the mounting position of the overhang bracket 1b with respect to the post 10, The corresponding upper and lower box members 13, 15, 19, 20 can always be positioned at the same level, but the height adjustment collar 26 must be fitted and removed according to the mounting position of the overhang bracket 1b. , It was extremely troublesome and troublesome. Further, since the height adjusting collar 26 is merely connected to the overhang bracket 1b by the chain 27, when not in use, it hangs down as shown in FIG. In some cases, the chain 27 may fall due to damage to the chain 27, and there is a problem in terms of safety.

The present invention solves such a problem of the prior art, and makes it possible to easily, quickly and surely adjust the height of the branching column, so that the corresponding upper and lower box members are always at the same level. An object of the present invention is to provide a temporary scaffolding member such as an extremely easy-to-use overhang bracket that can be positioned.
