Abstract

PURPOSE: To improve workability, insulation performance, sound shielding, fire resistance, strength or the like by filling inorganic particles and binder inside a space of a floor panel enclosed by metal front and rear plates by means of centrifugal injection and hardening. CONSTITUTION: A square flat-shaped metal front plate 1 and a press-formed metal rear plate 2 including ribbed portions are assembled to one united body by welding or the like and a hollow portion 6 is formed inside, and an injection hole 4 for a filler is provided at the center in the rear plate 2 of a floor panel. Next, the floor panel is fixed on a turn table in such a manner that the floor panel can be rotated around the injection hole 4 is a center, inorganic particles 3 are injected together with a binder through the injection hole 4, and the mixture can be quickly and fully filled to every part of the hollow portion 6 by utilizing centrifugal force. In this way, filling can be made easier, light to heavy weight products can be manufactured as desired thereby constituting access-free floor panels having excellent insulation ability and sound shielding performance.
