PURPOSE:To prevent the vibrtation of a floor panel and facilitate the carrying-in and connection works in execution by installing the floor panel on an installatiton rack board, and engaging the base board and the floor panel by a plurality of fixed vibration suppressing CONSTITUTION:A plurality of L-shaped vibration suppressing bodies 5 which are made of metal are prepared. An engagement groove 35 is formed on the vibration suppressing body 5, so as to conform to the shape of the basic edge of a rib 64 which is formed integrallay with a floor panel 4. A plurality of vibration suppressing bodies are fixed on the upper surface of a base 3. Then, a bathtub placement type floor panel 4 which is formed by integrally molding a washin field part 14 in one half part and a bathtub placement part 24 in the other half part is placed on the supporting rod 11 of an installation rack base 1. At this time, the rib 64 is fitting-engaged with the engagement groove 35 of the vibration suppressing body 5. The vibration in the longitudinal and lateral directions of the floor panel 4 is prevented by the base 3 through the vibration suppressing body 5. |
