DRAINAGE STRUCTURE OF BATH ROOM WATERPROOF PAN
To provide a drainage structure of bath room waterproof pan that enables a drain trap to be stably supported without increasing manufacturing cost by keeping lightness in weight of the bath room waterproof pan.SOLUTION: A drainage structure 8 of a bathtub side waterproof pan 1 comprises: a foam layer 10a; a skin layer 10b that covers a top face of the foam layer 10a; a drain trap 20, which has an annular support flange part 16 formed on a peripheral edge part of a drainage opening and an annular receiving part 23 along an undersurface of the support flange part 16; and a fastening flange 40, which has an annular flange part 42 along a top face of the support flange part 16. In a connected state of the drain trap 20 and the fastening flange 40, as the receiving part 23 and the flange part 42 hold the support flange part 16 by pinching, the drain trap 20 is supported by the bathtub side waterproof pan 1. The skin layer 10b has an upper face part 10x, which covers the top face of the support flange part 16, and a cylindrical droop part 10y, which droops from the upper face part 10x and covers an inner peripheral surface of the support flange part 16 at the drainage opening.SELECTED DRAWING: Figure 3
【課題】浴室用防水パンを軽量に維持し製造コストを上げずに、排水トラップを安定して支持することができる浴室用防水パンの排水構造を提供する。【解決手段】発泡体層１０ａと、発泡体層１０ａの上面を覆う表皮層１０ｂと、を備えた浴槽側防水パン１の排水構造８において、排水口の周縁部に形成された環状の支持鍔部１６と、支持鍔部１６の下面に沿う環状の受部２３を有する排水トラップ２０と、支持鍔部１６の上面に沿う環状のフランジ部４２を有する締付フランジ４０を備えている。排水トラップ２０と締付フランジ４０の連結状態において、受部２３とフランジ部４２が支持鍔部１６を挟持することにより、排水トラップ２０が浴槽側防水パン１に支持されている。表皮層１０ｂは、排水口において、支持鍔部１６の上面を覆う上面部１０ｘと、上面部１０ｘから垂下して支持鍔部１６の内周面を覆う筒形状の垂下部１０ｙとを有している。【選択図】図３
