<p>PURPOSE:To install each of handrail posts vertically to a concrete skeleton which is waveringly inclined in the longitudinal direction or cut-off inclined a the same height. CONSTITUTION:A pair of erected walls 15 whose opposed surfaces form a recessed curved part, are installed to a bracket 10 loaded fixedly on a concrete skeleton 1. A rotary spacer 30 having a curved sliding connection part 33 which is swelled out in shape and fits into a curved part 16, is interposed between the erected walls 15 and a handrail post 3. They are fastened with bolts and nuts 41 and fixed with fixing screws 42 to prevent them from turning. Since the rotary spacer 30 and the handrail post 3 have long holes 33 and 4 in the vertical direction, they can turn to the bracket 10 while the handrail 3 is adjustable about its height, it is, therefore, possible to install each of the handrail posts 3 vertically and at the same height irrespective of the installation condition of the concrete skeleton.</p> |
