Claims

[Scope of Claim for Utility Model Registration] 1. A backfilling device for sealingly backfilling the surroundings of pipes in through holes formed in the structure of a building with noncombustible material such as mortar, a sleeve embedded to form the inner surface of the through hole and having an inward flange on one end edge; an eccentric inner ring having an inner diameter approximately equal to the outer diameter of the pipe and fitted onto the pipe; and the sleeve an eccentric outer ring having an outer diameter substantially equal to the inner diameter of the eccentric outer ring and having an inner diameter substantially equal to the outer diameter of the eccentric inner ring, the outer circumferential surface of the eccentric inner ring and the inner circumferential surface of the eccentric outer ring being fitted into the sleeve. is a backfilling device for pipe penetrations, which is formed with uneven surfaces that closely mesh with each other. 2. The device according to claim 1, wherein the outer circumferential surface of the eccentric inner ring is a concave surface, and the inner circumferential surface of the eccentric outer ring is a convex surface. 3. The device according to claim 1, wherein the outer circumferential surface of the eccentric inner ring is a convex surface, and the inner circumferential surface of the eccentric outer ring is a concave surface.
