The lower part of is formed to be a little thin so that it can be inserted into the support column 8. The lower portion of the handrail supporting column 9a may be formed on a known outer diameter adjusting shaft whose outer diameter can be adjusted to a large or small value.

The temporary passage is formed by projecting end portions 1 of a plurality of horizontal steel materials.
Since it is provided along the side surface, it is necessary to connect the side surface steel materials 2 as shown in FIG. 3. In that case, between the two side surface steel materials 2 which are adjacent to each other in the longitudinal direction, a cross-section cord slightly smaller than the cross section of the side surface steel material is used. A V-shaped connecting steel material 10 is arranged and can be connected by a bolt 11. In addition, connected steel material 10

Further, the locking piece 25b and the parallel side of the bracket 25a have pin holes 25c, respectively. 25d is provided, and the pin 26 inserted into these pin holes is attached to the bracket 25a via a chain. Then, when connecting the two side surface steel materials 2 arranged in the longitudinal direction, the locking projections 24 at the ends of one side surface steel material are inserted from above into the locking holes 22 in the lower surface of the other side steel material, The stopper member 25 is pushed in as shown by an arrow A in the figure to insert the locking piece 25b into the locking holes 21 and 23 of the upright surfaces of both members, and further the pin 26 to the pin holes 25d, 25e and 25c.
To connect. In this state, the locking projections 24 and the pins 26 are oriented in the direction orthogonal to the locking pieces 25b, so that the locking projections 24 and the pins 26 do not easily come out and can be firmly connected.

Further, in order to maintain the interval between the pair of side surface steel members 2 arranged at the passage width interval, as shown in FIG.
The reinforcing members 12 are connected in a letter shape. Therefore, locking holes are provided at both ends of the reinforcing member 12, and the locking holes can be engaged with the retaining pins provided on the side surface steel material 2.

The connecting member 4, as shown in FIG.
Locking pieces 4a are provided on both ends of the bar member so as to project downward, and the locking pieces 4a can be engaged with the holes of the locking hole members 6 of the side surface steel material. The locking piece 4a is formed in a quadrangular cross section corresponding to the hole cross section of the locking hole member 6, and its tip is made slightly thin to facilitate insertion. Although the connecting member 4 has a quadrangular cross section, the connecting member 4 has a round cross section or the like so that the hook 5a at the end of the scaffolding plate 5 is formed.
May be easily engaged, and the locking piece 4a may have a sectional shape corresponding to the locking hole member 6. The connecting agent 4 has a constant length, but as shown in FIG. 6, the central portion is formed into a double cylinder so that the length can be adjusted. The passage width may be changed and adjusted by inserting a pin or the like at an appropriate position and fixing the length. As shown in FIG. 2 (b), the scaffolding plate 5 is provided with two hooks 5 a at both ends of an elongated plate portion, and the hooks 5 a on both sides are arranged between a pair of side surface steel materials 2. The connecting member 4 can be engaged to form a passage floor.

In the case where a temporary passage is provided around the outer wall of a building under construction by using the side surface steel material 2, the connecting member 4 and the scaffolding plate 5 which constitute the above-mentioned prefabricated temporary passage, a plurality of constructions of the building under construction are provided. The side surface steel materials 2 are arranged in two rows along the protruding end portion 1 of the horizontal steel material at passage intervals, and the locking hole members 6 of the side surface steel materials 2 on both sides are arranged.
The locking pieces 4a at both ends of the connecting member 4 are inserted into the connecting member 4 to connect the side surface steel members 2 to the passage width interval. Next, the side surface steel material 2 is fixed to the protruding end portion 1 of the horizontal steel material by a clamp or the like.
When the temporary passage is longer than the side surface steel material 2, the side surface steel materials 2 adjacent to each other in the longitudinal direction are connected by the bolts 11 via the connection steel material 10, and the connection material 4 connects the passage width intervals as described above.

Next, the hooks 5a at both ends of the scaffolding plate 5 are locked to the adjacent connecting members 4 to form a passage floor. In this embodiment, the three scaffolding plates 5 are locked to one connecting member 4 to form a passage having a total width of the three scaffolding plates. Further, the handrails 9 can be provided on both sides of the temporary passage by inserting and fixing the support columns 9a of the handrails into the respective column support cylinders 8 of the side surface steel materials 2 arranged at the passage width intervals. By assembling in this way, a temporary passage can be provided around the building under construction.
