<p>PROBLEM TO BE SOLVED: To prevent the corrosion in the bottom parts of fence stanchion by burying the whole parts or parts of the bottom sides lower than flanges provided in the intermediate part in the vertical direction of bracing struts in the balcony floor and fitting and fixing the lower end of the fence stanchion to the upper side of the flanges. SOLUTION: Parts lower than positioning pins in buried parts of bracing struts 2, 3 are inserted in mortar as grout filled with a vertical hole of a concrete block constituting a circumferential edge part of a balcony floor 1. After hardening of the mortar, respective supports 5 of respective fence units 41, 4b are externally fitted in fitting parts 10 of the bracing struts 2, 3 in such a state as the bottom end faces abut to flanges, and screws are threadly engaged therein from the outside of the supports 5 so as to be fixed. The bottom ends of the supports 5 are allowed to abut to with the flanges of the bracing struts 2, 3 and prevented from directly touched with the floor face of the earthen floor concrete to be placed so as to prevented corrosion. The bracing struts 2, 3 themselves are simply prevented rust by coating at low cost.</p> |
