In addition, a fire resistant cover 6 fitted with a piping connector 7 is installed in a lower part of the opening 1 to cover this opening 1. Then, a Japanese toilet bowl 8 is inserted into the through hole from the upside and supported by an engaged part 4d, and the connector 7 is connected to a connection 8f formed in a drain port part 8c of the bowl 8. In addition, rock wool 11 is applied over both inner and outer circumferential surface of the cover 6, the connector 7 and a peripheral part of the opening of a deck plate 3. n COPYRIGHT: (C)1989,JPO&Japio |
