2. Description of the Related Art For indoor piping of houses, buildings, factories, etc., such as water supply piping, drainage piping, and air conditioning piping, these piping must be fixed to the building. In conventional piping, a holder is fixed to a pipe or a pipe member such as a joint or a valve provided in the middle of the pipe, and the holder is fixed to a building material such as a floor, a beam, or a ceiling. Is common. In particular, since the vertical drainage pipes of high-rise buildings combine the drainage water of each floor to flow down to the lower floors, a pipe with a relatively large diameter is used and the weight is heavy, and the drainage water of each floor is a vertical drainage pipe. At the merging joint where the merging occurs, the horizontal drainage flow collides with the wall surface of the merging joint and flows down, so the vertical drainage pipe including the joint vibrates, so the vertical drainage pipe should be firmly fixed to the building. Is required.

For example, in Japanese Patent Laid-Open No. 2000-193148, when installing a drainage pipe joint of an apartment house or the like into a sleeve hole of a concrete slab, the drainage pipe joint is supported on the slab to form a drainage pipe joint. An invention relating to a backfill backing plate support used when backfilling a gap with a sleeve hole with mortar is described.
