Japanese Patent JP2018040239

A

PROBLEM TO BE SOLVED: To provide a sediment inflow prevention plate for an embedded box of which a single type is compatible with water pipes of different outer diameters, the sediment inflow prevention plate being fitted readily on a water pipe without twisting of a base plate part.SOLUTION: A sediment inflow prevention plate 1 for an embedded box has, at a peripheral part surrounding a water pipe installation hole part 21 of a base plate part 20, a plurality of elastic tongue pieces 25 formed radially with the water pipe installation hole part 21 at a center, the elastic tongue piece protruding toward the water pipe installation hole part 21 from the peripheral part. Furthermore, the elastic tongue piece 25 is curved in a direction along a plate thickness direction of the base plate part 20 toward the water pipe installation hall part 21 when a water pipe P is not installed in the water pipe installation hole part 21, and comes in contact with the water pipe P elastically when the water pipe P is installed in the water pipe installation hole part 21 through the slit part 22 for passing a water pipe.SELECTED DRAWING: Figure 1
