摘要

PROBLEM TO BE SOLVED: To provide a construction unit of a balcony with a handrail, which not only allows the operator to correctly set a core support for mounting the handrail, at a projective edge of the balcony, but also eliminates inconveniences of pooling of water at an installation location of an anchor and repair of the pooled installation location, to thereby improve the workability and simplify a temporary safety fence, and to provide a method of settling the handrail in the balcony, and the core support and a temporary handrail bar for use in the method.;SOLUTION: According to the construction unit of the balcony, a concrete construction portion of the balcony which has the projective edge 3 erected at the edge of a floor section 1, for mounting the handrail thereon, is dividedly molded in the factory beforehand as the projective edge 3 or the floor section 1 with the projective edge. Further a construction block Pa serving as a foundation for mounting handrail supports on the projective edge, is obtained by inserting and embedding therein the anchors, as an essential body, and splice cores connected to the respective anchors, the plurality of handrail supports inserted into the respective splice cores and secured to the same, or a handrail T assembled together with the handrail supports, together with the construction block form one unit.;COPYRIGHT: (C)2006,JPO&NCIPI
