The fixing bracket 1 is substantially U-shaped so as to sandwich the flange portion 2a of the H-section steel 2 and has a tapered surface 4a on the upper surface of the inner portion 3 and is accommodated in the inner portion 3 of the metal member 4. A wedge member 5, and a bolt 6 is inserted horizontally from a side surface of the metal fitting body 4 and screwed into a nut 7 provided on the wedge member 5, and a handrail support 8 is provided on the upper surface of the metal fitting body 4. Are fixed by welding. When the bolt 6 is turned in a state where the fixing metal fitting 1 is fitted to the flange portion 2a, the wedge member 5 slides rightward from, for example, the position indicated by a two-dot chain line in FIG. The flange 2a is sandwiched between the lower body 4 and the lower plate 4b.
Thereby, the metal fitting body 4 and the wedge member 5 are integrally fixed to the flange portion 2a.

Is easy to operate because only the bolts 6 need to be tightened, and has the advantage of good workability because the bolts 6 are oriented sideways. There is also a disadvantage that the tightening becomes unstable as the angle becomes obtuse. Therefore, in actual use, the flange thickness range in which the fixing bracket 1 can be used is narrow, for example, 8 mm to 23 m.
One type of fixing bracket 1 cannot cope with the flange thickness range of m, and a plurality of types must be prepared. Although the flange portion 2a is not shown in the figure, it is actually slightly tapered on the lower surface and may be slightly thicker on the inner side than on the edge side. It is necessary to match the upper surface 4c of the taper with the taper, which is complicated. If the upper surface 4c is not matched with the taper, the stability is slightly lacked.

する構造である。The upper member 14 is formed by press-forming a steel plate. The periphery of the upper member 14 is bent downward at a right angle to provide rigidity, and a circular concave portion 14a is formed on the upper surface side. The lower end of 11 is inserted and fixed by welding. The lower member 16 is also made by press-forming a steel plate. The periphery of the lower member 16 is bent upward at a right angle, and the connecting arm 16a is extended upward. Member 14
It is connected to. Further, a portion of the lower member 16 outside the connecting shaft 15 is a receiving portion 16 to which the lower end of the bolt 20 abuts.
The height is slightly higher than that of the portion 16c sandwiching the flange portion 12a. In this embodiment, the tip of the bolt 20 is rounded, and the bolt 2
A concave groove 16d is formed in a receiving portion 16b of the lower member 16 for receiving the leading end of the "0" to be slidably guided in a groove length direction (left-right direction in FIG. 1) in a groove length direction. doing. As a result, the bolt 20 comes into surface contact with the receiving portion 16b of the lower member 16, and when the lower member 16 rotates around the connection shaft 15 in accordance with the thickness of the flange, the lower member 16 Since the guide 16 is guided by the bolt 20 fitted into the concave groove 16d, a stable operation can be performed without blurring. In this case, as shown in FIG. 7, when the concave groove 16d is formed deeply, the guiding action of the bolt 20 is effectively performed, and the operation is further stabilized. Further, as shown in FIG. 3, the clamp piece 18 of the embodiment has a structure in which both ends of a long and thin steel plate are bent, and the bent both ends 18a are supported by the shaft 17.

To fit. Next, when the bolt 20 is screwed in, the lower end of the bolt 19 is received by the receiving portion 16 b of the lower member 16.
1, the lower member 16 rotates clockwise in FIG. 1 around the connecting shaft 15, and the clamp piece 18 at the distal end of the lower member 16 is strongly pressed against the lower surface of the flange portion 12 a. In this case, since the clamp piece 18 is rotatably attached to the lower member 16, the flange portion 12 a
Surface contact with the lower surface of the upper member 14 and the clamp piece 1
8 strongly clamps the flange portion 12a. In this way, the fixing bracket 13 is firmly fixed to the flange portion 12a, and the column 11 integral with the upper member 14 is firmly fixed to the H-shaped steel 12. When the height H of the nut 19 is increased, the bolt 20 can push down the lower member 16 more stably.

うにすると，強固な緩み止めとすることが可能である。In the above-described embodiment, the upper member 14 and the lower member 16 are manufactured by press-forming a steel plate. However, it is naturally possible to manufacture using a simple thick plate. In the embodiment, the connecting member 16a is provided so that the upper member 14 is flat and the upper member 14 extends upward on the lower member 16 side. Conversely, the connecting member 16a is provided on the upper member 14 side where the lower member 16 is flat. Can also. The means for fixing the support 11 to the upper member 16 is not limited to the structure of the embodiment, but may be, for example, a method of fixing to the flat upper surface of the upper member 14 by welding, a method of fixing with bolts instead of welding, or any other arbitrary method. It is. Also, the shape of the clamp piece 18 is not limited to the shape obtained by bending an elongated steel plate as shown in the illustrated example, and may be arbitrary.
Any shape may be used as long as it can make surface contact with the lower surface of the flange portion 12a. As shown in FIG. 6, a nut 21 is interposed between the head of the bolt 20 and the upper member 14, and after the bolt 20 is tightened, the nut 21 is tightened, and the nut 21 and the lower nut 19 are tightened. When the upper member 14 is sandwiched between and, it is possible to provide a firm loosening prevention.
