The embodiment shown in FIG. 9 shows a structure in which the fixed base 2 is fixed to the beam member 45 formed of C-shaped steel or the like. In this case, the fixed metal piece 46 shown in FIGS. 11 and 12 is used. To use. The fixed hardware 46 is a pair of bolts 48 at the diagonal corners on the back of the support plate 47.
And the other diagonal corners are provided with shafts 50 respectively and the receiving nut 49 is fixed to the center of the surface of the support plate 47 by welding or the like. A long hole 52 and a notch hole 53 provided in the are inserted. Then, as shown in FIG. 9A, the support plate 47 is arranged on the front side of the beam member 45 such that the bolts 48 are inserted into both outer edges of the beam member 45, and the long hole 52 and the notch hole 53 are formed. A pressing plate 51 is placed in the back of the beam member 45 with the pair of bolts 48 inserted respectively, and a nut 54 is screwed onto each bolt 48 to tighten the bolts 48 between the supporting plate 47 and the pressing plate 51. Beam material 45
And the fixed metal member 46 is fixed to the beam member 45. At this time, the pair of shafts 50 are positioned in the vicinity of both outer edges of the beam member 45, so that the fixed metal object 46 is prevented from rotating. Next, as shown in FIG. 9 (b), a receiving nut 49 is inserted into the horizontal cylinder 10 of the fixed base 2 from the opening at the tip thereof, and the tip of the bolt 55 inserted into the horizontal cylinder 10 is received from the hole 12.

[Advantages of the Invention] As described above, the work handrail according to the present invention has a fixed base provided with an insertion tube fixed to a structural member by bolting and opening upward, and a lower end inserted into the insertion tube of the fixed base. And a handrail post having a substantially U-shaped receiver attached to the outer surface of the upper part, and a handrail frame formed in a substantially rectangular shape and hooked and engaged with the receiver to be mounted between the handrail posts. In addition, one vertical piece of the handrail frame is provided with a coupling tool having a substantially horizontal U-shaped cross section which is engaged with the vertical piece of the adjacent handrail frame. The handrail post can be attached to the base by inserting it into the insertion tube, and the handrail frame can be attached to the handrail post by hooking engagement with the receiver, and the handrail frame can be connected to the connecting tool. It can be done by engaging, and the work is simple by inserting, hooking and engaging. The handrails can be assembled and disassembled, the work can be done without trouble, and the normal work at the construction site is not hindered. The components can be finely disassembled, such as a handrail pillar and a handrail frame, so that they can be easily carried in and out of a construction site. In addition, the handrail frame is formed by a pair of U-shaped frame halves each having an upper piece and a lower piece at the upper and lower ends of the vertical piece, and slide tools are attached to the tips of the upper and lower pieces of each frame half. The handrail frame is fixed to the above-mentioned approximately square shape by connecting the upper piece and the lower piece to each other by sliding the upper piece and the lower piece of the other frame half through the slide tool of the one frame half body slidably. Since it is formed in a mold, it is of course possible to adjust the widthwise dimension of the handrail frame by sliding a pair of frame halves. The upper and lower pieces are slid in a state that they are inserted into a slide tool fixed to the tip of the upper and lower pieces of the other frame half, and the upper and lower pieces of each frame half have the same thickness. Can be slidably connected even if it is formed into the same shape, and the entire handrail frame is formed with members of the same thickness Doo and is enabled, in which can have high working handrail to form a whole uniform intensity safety handrail frame. In other words, when slidably coupling a pair of frame halves, insert the upper and lower pieces of the other frame half into the tubular upper and lower pieces of the one frame half. If this is selected, the upper and lower pieces of one frame half must be formed with a large diameter, and the upper and lower pieces of the other frame half must be formed with a small diameter. However, in the present invention, the entire handrail frame can be formed of a member having the same thickness, as described above.
