（４）とされたものを内設している。As the S-like inorganic wide particles constituting the free access floorboard of the present invention, mixing into cement up to 29 is exemplified,
Examples have been given of injecting and filling before solidifying, or filling and solidifying one of the front and back plates and then integrating the two, but after forming and assimilating the metal to a predetermined shape, 2) You can fill it in between. An example of this is shown in FIG. 8 (vertical sectional view of the end of the floorboard). In this example, the side wall of the bowl-shaped metal front plate (1) has an outer protrusion (21) for engaging with the metal back plate (2). ) has a structure in which an inner surface protrusion (22) is provided on the bowl-shaped outer wall so as to be integrally engaged with each other. These metal surface plates (
1) and the metal face plate (2), when these are assembled, sometimes the same shirasu balloon inorganic width particles (3) as in the previous embodiment are mixed with cement together with carbon fibers. A core molded body (4) formed by molding and solidifying the core molded body (4) is installed inside the core molded body.
