Common hole 1 formed by stacking
Bolts 17 are inserted into 7'and 17 "and tightened with nuts to form a horizontal landing 6 and an inclined ladder 4 with an opening angle of about 120 degrees between the ladder 4 and the landing 6.

At the outer end of the landing 6, there is provided a bottom plate 19 for connecting the lower edges of the side plates 6'and 6 ', and the bottom plate 19 is provided with elongated holes 10 and 10 facing inward and outward, as shown in FIG. The bending body 8'of the iron pipe clamp metal fitting 8 is slidably supported in the long hole 12 by bolts and nuts, and the opening and closing bending arm 8 "
The end of the horizontal frame 7 is clamped to the end of the main body 8'with a bolt 12 ', and the horizontal horizontal frame 7 made of an iron pipe is clamped. Then, by sliding the clamp fittings 8 and 8 along the long holes 10 and 10, it is possible to cope with the interval T.

The tilting ladder 4 includes two horizontal tilting rods 4 ',
4'is connected by a tread plate 20, vertical angle short pipes 21, 21 are welded to the upper and lower ends of the tilt rods 4 ', 4', and fitting fittings are projected downward from the long vertical angle pipes 22, 22. 23 is removably fitted to the vertical rectangular pipes 21, 21 and the slanting rods 4 ', 4'and horizontal handrails 9, 9 are welded to the upper ends of the long vertical rectangular pipes 22, 22. This handrail 9 is an inclined rod 4 ', 4'
It can be provided on one or both.

Reference numeral 24 in the figure denotes a fastening bolt for fixing the fitting 23 to the vertical short tube 21, and 25 denotes the landing 6
