WASTEWATER COLLECTING PIPE SUPPORT FITTING, AND WASTEWATER COLLECTING PIPE INSTALLATION METHOD USING IT

PROBLEM TO BE SOLVED: To easily install a wastewater collecting pipe in a through hole of a concrete slab by using a support fitting. SOLUTION: The support fitting 3 is formed by providing a pair of opposing horizontal fixing pieces 31, and a support band 34 installed horizontally via a connecting plate slantly arranged from the fixing piece 31. The support band 34 is formed like an inverted frustum with an inner circumference as a slanted face such that upper and lower ends comprise concentric circles with a large upper end diameter and a small lower end diameter, and a vibration proofing material 35 is arranged on its inner circumferential face. The support fitting 3 is set in the through hole 11 of the concrete slab 1, and then the wastewater collecting pipe 2 is installed so as to drop it onto the support band 34. The support band 34 contacts a slanted trunk part 23 of the A wastewater collecting pipe 2 by its face to carry out stable support of the wastewater collecting pipe 2, and the wastewater collecting pipe 2 is installed in a position suiting connection of lateral branch pipes.
