SOLUTION: A pair of support arms 1 separated on right and left is provided, the support arm having a handrail receiver 1a at a tip for fixing a handrail C, and a back plate 1b at a base end. Two spacers 2, 2 on top and bottom are used for fixing the pair of support arms 1, 1 to each other, the two spacers 2, 2 on top and bottom being interposed and fixed between the pair of support arms 1, 1 on right and left and fastened with screws 2a, 2a. The configuration allows the pair of support arms 1, 1 on right and left to be fixed to each other leaving a prescribed interval, the pair of support arms 1, 1 being separated by a width of the spacer 2, with the two spaces 2, 2 on top and bottom interposed between the pair of support arms 1, 1 on right and left.EFFECT: Load bearing strength of a handrail C is enhanced, by installing a pair of support arms 1, 1 on right and left at separate locations. The handrail C is stabilized by being fitted on handrail receivers 1a, 1a, and workability when fitting and installing the handrail C to the handrail receivers is enhanced.SELECTED DRAWING: Figure 1 |
