SLEEVE HOLDER

PROBLEM TO BE SOLVED: To provide a sleeve holder capable of ensuring a covering thickness of a reinforcement and coping with a sleeve material and the reinforcement of a various diameter sizes while the reinforcement and the sleeve material can be connected even from a plurality of directions. SOLUTION: The sleeve holder 1 includes a band member 3 wrapped around an outer periphery of a sleeve material 2 which is embedded in a concrete skeleton for ensuring a piping hole and a connecting member 5 for connecting the band member 3 and a reinforcement 4 constituting the concrete skeleton. The connecting member 5 has a first retaining part 7 having a C-shaped cross section formed on one side of the connection part 6 and a second retaining part 8 having a C-shaped cross section with a diameter larger than that of the first retaining part 7 formed on the other side of the connection part 6. The connection part 6 has a space between the reinforcement 4 and the sleeve material 2 long enough for ensuring the covering thickness not less than the one predefined by the building codes.
