PURPOSE:To obviate the need for upward rail mounting operation on a trestle to the underside of a ceiling slab, and to conduct fixing to slab concrete firmly while minimally inhibiting the sectional defect of slab concrete, and to hang and support ceiling-inside equipped pipings without trouble. CONSTITUTION:A plurality of fixing members 2 are installed to the upper section of a rail body 1 having a downward opened and internally spread groove (a) at proper intervals in the longitudinal direction of the rail body 1, thus constituting a hanger support rail A. The rail A is mounted onto the underside of a ceiling stab under the state, in which the fixing members 2 are buried into slab concrete. |
