  Next, the method of using the temporary pole for construction site according to the present invention will be described. The temporary pole main body 52 shown in FIGS. 10 to 12 includes the poles 1 of the number of poles 1 corresponding to the length necessary for the temporary pole main body 52. Assembled by connection. As shown in FIG. 4A, the poles 1 are connected to each other by inserting the insertion small-diameter shaft 6 at the lower end of the upper pole 1 into the receiving cylindrical part 7 at the upper end of the lower pole 1 to the limit depth. The locking pin 11 of the locking means 8 provided in the small-diameter shaft portion 6 for insertion is fitted into one of the locking holes 16 provided in the receiving cylindrical portion 7 on the lower pole unit 1 side by the elastic force of the leaf spring 9. This is done by combining them. At this time, the lower end of the insertion small-diameter shaft portion 6 on the upper pole single body 1 side is received by the plurality of circumferential projecting portions 15 provided on the receiving cylindrical portion 7 on the lower pole single body 1 side. In the temporary pole body 52 assembled in this way, all the pole single bodies 1 connected to each other are integrated by the locking means 8 so that they cannot be rotated relative to each other and cannot be pulled out. .

  The temporary pole shown in FIG. 10 is a temporary pole body 52 that is assembled as described above, and is erected at a predetermined position on the ground using the pile pole single body 2. The pile pole single body 2 is driven vertically to a predetermined depth below the ground using the tip metal fitting 2b with the hammering cap 2c covered on the receiving cylindrical portion 17 at the upper end. As shown in FIG. 4B, the temporary pole body 52 is connected to the pile pole single body 2 by inserting the small diameter shaft portion 6 at the lower end of the temporary pole main body 52 into the receiving cylindrical portion 17 at the upper end of the pile pole single body 2. The locking pin 11 of the locking means 8 provided in the small-diameter shaft portion 6 for insertion is inserted into one of the locking holes 23 provided in the receiving cylindrical portion 17 on the pile pole single body 2 side. This is performed by fitting with the elastic force of the spring 9. Therefore, the temporary pole main body 52 is integrated with the pile pole single body 2 so as not to rotate relative to the pole axis and not to be pulled out. At this time, the lower end of the insertion small-diameter shaft portion 6 at the lower end of the temporary pole body 52 is received by the arcuate protruding portion 22 provided in the receiving cylindrical portion 17 on the pile pole unit 2 side.

  Further, as shown in FIGS. 11 and 12, the temporary pole body 52 assembled as described above is inserted into the single pole insertion hole 21 of the water injection type base 4 placed at the temporary pole installation position on the ground or the like. By making it stand by itself, the temporary pole body 52 alone can be used as a temporary pole. Further, as shown in FIG. 11, the lower end portion of the temporary pole body 52 is connected to the pole unit 5a of the fixing base 5 which is fixed to the temporary pole setting position such as on the floor slab by an anchor bolt or the like, and the fixing base is connected. 5 can also be used as a temporary pole that can be erected at a predetermined position. Furthermore, the temporary pole body 52 is combined with the clamp mounting pole unit 3 and the pipe clamp 19 or the U-shaped clamp 20 mounted on the clamp mounting pole unit 3 is used to horizontally lay the steel pipe handrail or It can also be used as a temporary pole that can be attached perpendicularly to the side of a plate of H-shaped steel placed on the ground. When the temporary pole body 52 is combined with the fixing base 5 or the clamp mounting pole single body 3 to form the temporary pole, similarly to the case where the temporary pole main body 52 is combined with the pile pole single body 2 to form the temporary pole, The small-diameter shaft portion 6 for insertion at the lower end of the temporary pole body 52 is inserted to the steel tube receiving cylindrical portion 17 provided in the pole single body 5a of the fixing base 5 or the clamp mounting pole single body 3 to a limited depth. Since both can be integrated by the lock pin 11 of the locking means 8, the temporary pole body 52 cannot be rotated relative to the fixing base 5 or the clamp mounting pole unit 3 around the pole axis. And it is integrated so that it cannot be pulled out.

  The temporary pole that can be erected at a predetermined position on the ground as described above can be used as illustrated in FIGS. In any use mode, the upper end of the temporary pole body 52 has the receiving cylindrical portion 7 of the uppermost pole unit 1 opened upward, so that the receiving cylindrical portion 7 of the uppermost pole unit 1 is opened upward. It is desirable to attach a self-luminous display 24 and a cone bar support cap 26 to the head. As shown in FIGS. 5B and 6C, the self-luminous display 24 and the cone bar support cap 26 have the mounting shaft portion 25 connected to the pole unit 1 at the uppermost end in the same manner as when the pole units 1 are connected to each other. What is necessary is just to insert in the cylindrical part 7 for receiving to the limiting depth, and to lock with the lock pin 11 of the latching means 8. As a result, a temporary pole is formed in which the self-luminous display 24 and the cone bar support cap 26 are integrated on the upper end of the temporary pole body 52 so as not to be relatively rotatable around the pole axis and not to be pulled out. Of course, instead of the self-luminous display 24 and the cone bar support cap 26, a cap having only a cap body covering the upper end of the receiving cylindrical portion 7 of the pole unit 1 is combined with the upper end of the mounting shaft portion 25. You can also

It is inserted into the receiving cylindrical portion 7 such as the single body 3 and the pole single body 5a of the fixing base 5 or the receiving cylindrical portion 17 made of steel pipe to the limit depth, and the small-diameter shaft portion 6 for insertion or the mounting shaft portion 25 is provided. What is necessary is just to lock by the latching means 8. FIG. As a result, the plate-like mounting members 33, 36, 40, and 47 of the various mounting parts that are fitted in the small-diameter shaft portion 6 for insertion or the rectangular mated portion 13 of the mounting shaft portion 25 are the poles directly below them. 1 and the pipe main body 1a connected to the upper side of the square mating portion 13 and the like, but positioned at the upper end of the pole unit 1 directly below, that is, the opening end portion 14 whose diameter has been expanded. The supported mounting part is supported more stably than the mounting part supported at the upper end of the tubular portion 17 made of steel pipe such as the pile pole single body 2.

  When mounting parts such as the reflector 32, the rope guide 35, the chain hook 39, or the signboard bracket 43 are attached to the temporary pole as described above, these mounting parts are attached to the small-diameter shaft portion 6 for insertion or the mounting shaft portion 25. The small fitting shaft portion 6 or the mounting shaft portion 25 is fitted to the square fitting portion 13 so as not to be relatively rotatable, and the locking means 8 does not allow relative rotation around the axis of the temporary pole body 52 by the locking means 8. As a result, the various attachment parts attached as described above are in a state where the circumferential direction is fixed with respect to the assembled temporary pole. Therefore, when the pole unit 1 or the like below the attachment part cannot be rotated around its axis, the small-diameter shaft part 6 for insertion or the attachment shaft part 25 to which the attachment part is attached is attached. When it is inserted into the lower pole unit 1 or the like and locked by the locking means 8, care must be taken that the orientation of the mounting part is the desired direction.

  Further, when the small diameter shaft portion 6 for insertion of the upper pole unit 1 or the shaft portion 25 for mounting the self-luminous display 24 or the cone bar support cap 26 is inserted into the lower pole unit 1 or the like to the limit depth, The height (thickness) of the square mating portion 13 exposed upward from the upper end of the pole 1 or the like on the lower side is set to the thickness of the plate-like mounting members 33, 36, 40, and 47 of the above various mounting parts. By configuring so as to be twice or more, for example, as shown in FIG. 10, two attachment parts such as a rope guide 35 (or chain hook 39) and a reflector 32 (or at a single intermediate height of the temporary pole) A signboard bracket 43) can be attached.

  The temporary pole for a construction site according to the present invention can be used as a temporary pole in which various safety measures can be easily attached to the intermediate height of the temporary pole in a predetermined direction.
