The metal support 10 comprises a plurality of band parts 12 holding the outer peripheral surface 7a of the drain pipe joint 6 by connecting the end parts 15 thereof to each other and fixed parts 21 holding the band parts 12 and fixed to the concrete slab 1. Each fixed part 21 comprises a holding part 22 holding the band parts 12 and a branch leg part 27 branched from the holding part 22 into fork shape and extending downward and fixing the lower end part 30 thereof to the concrete slab 1. Each branch leg part 27 is formed so as to be rotatable on a lower end part 3 side around the holding part 22 and to be fixed to the holding part 22 after the rotation.
