  As a handrail for fall prevention, first of all, robustness is required for a long period of time, and it is used with a sense of security with little shaking when a load is applied by gripping or leaning on the handrail. There is a need to be able to do it. In the pillar for aluminum handrail according to Patent Document 1, the rust preventive plating layer is peeled off by the screw because the pillar anchor or anchor reinforcing bar made of the steel material subjected to rust prevention plating and the lower end of the pillar are screwed. Since the rust prevention effect is reduced by use, rainwater or the like that has entered from the screw stoppers causes rust to appear and deteriorates the appearance and adversely affects the strength and safety of the handrail. Moreover, even if there is no problem in strength, the user cannot use it with a sense of security due to the occurrence of rust.

  In the aluminum handrail support according to Patent Document 2, the anchor bolt is only fixed to the lower end portion of the aluminum handrail support, and the aluminum handrail support has a height of at least about 1150 mm even if the design strength is satisfied. Since it is necessary, the upper part of the aluminum handrail support column into which the anchor bolt is not inserted feels swinging when a load is applied. In addition, the anchor bolt is simply inserted through the bolt screw-in cylinder, and the two are not joined together, and the aluminum handrail support pillar may fall out from the anchor bolt when a load in the pulling direction is applied. There is also. In the aluminum handrail support according to Patent Document 1, since the support anchor is only inserted into the lower end of the support and is only screwed to the aluminum handrail support, there is a risk of swinging and the pulling direction. There is also a possibility that the aluminum handrail support pillar is dropped from the support anchor when the load is applied.

  Further, in the aluminum handrail support according to Patent Document 2, although one end of the anchor bolt is screwed into the bolt screw-in cylinder, the female screw is not engraved on the inner peripheral wall of the bolt screw-in cylinder. The anchor bolt is press-fitted into a bolt screw-in cylinder having a slightly smaller inner diameter, the two are not integrated, and there is a possibility that loosening may occur due to aged use. In addition, various types of aluminum handrails have recently been favored as exteriors that impress the exterior of buildings.
