An L-shaped piece 18 having the same shape is fixed by welding or the like. The side wall edge frame material 4 is fixed by placing a projecting piece 21 extending from the lower locking part 17 on the upper end of a support member 20 for holding the decorative board 19 attached to this L-shaped piece 18. Furthermore, a rising piece 22 having an inverted L-shaped cross section is provided in the center of the side wall edge frame material 4 in the horizontal direction, and is fitted into a recess 15 provided in the main body part 8 of the mounting bracket 1 and fixed with screws.

As shown in detail in FIGS. 3 and 4, the support column 6 of the handrail 5 is a hollow member with a rectangular cross section, and a grooved line 24 is formed along the longitudinal direction on the side surface 23 that is the front outside when installed. There is. This groove 24 is wider than the head 25a of the fixing bolt 25 for attachment and the nut 26, so that a tool can be inserted to perform tightening work. Further, three bolt holes 28 are formed in the bottom 27 of the groove 24 so that three fixing bolts 25 can be attached thereto. Furthermore, the side surface 29 facing the side surface 23 provided with the grooved line 24 is
It serves as a contact surface for the above-mentioned mounting bracket 1 and side wall edge frame material 4, and three bolt holes 30 are similarly drilled at positions corresponding to the bolt holes 28 in the bottom portion 27.

A pair of reinforcing walls 32, 32 are formed along the longitudinal direction between the bottom 27 and the side surface 29 of the groove 24 at an interval slightly larger than the diameter of the threaded portion 31 of the fixing bolt 25. The holes 28, 30 are located between the reinforcing walls 32, 32, respectively.

The fixing bolt 25 is passed through the side wall edge frame material 4 from the main body 8 side of the mounting bracket 1, and then passed through the bolt hole 30 between the reinforcing walls 32, 32, and the tip of the threaded portion 31 is inserted into the groove 24 from the bolt hole 28. It is made to protrude and is tightened with a nut 26. In the figure, 33 is a lid, and grooves 24
