In addition, various other materials such as natural aggregates and artificial aggregates other than the above may be mixed as the aggregate. For example, lightweight aggregates such as shirasu balloon and perlite have been mixed as aggregates. Further, in recent years, materials formed by crushing glass waste materials as aggregates have been mixed.
In that case, the mixing ratio of cement and waste glass is about 1: 1 in terms of volume ratio.

材料の使用には大きな問題点があった。The above-mentioned conventional OA floor panels are heavy in weight because they use a large amount of sand or gravel as an aggregate in the ceramics type, so that they are easy to transport. There was a problem in construction and maintenance. Also,
The metal-based material had a bad walking feeling due to a metallic sound generated when it came into contact with the metal or an echo sound due to reflection of sound in the hollow portion. Further, in addition to the above-mentioned problem of walking feeling, the synthetic resin system has problems of strength, problems of securing materials, and problems that cannot be nonflammable. In addition, an OA floor panel that is a combination of a metal-based one and a ceramic-based one has a weight of about 50 cm square and a thickness of about 25 mm.
Since it weighed more than Kg and was unnecessarily heavy, and had problems in terms of transportation, construction, and maintenance, as described above, a mixture of lightweight aggregate in the hollow part of the hollow metal panel was used. Has been adopted. However, the lightweight aggregates such as Shirasu balloon, perlite, and ceviolite are
It is a natural material, and it has become difficult to procure these materials domestically in recent years, and there is a big problem in using these materials from the viewpoint of the global environment.

However, it still has a weight of about 9,5 kg, and has a drawback of high weight and high cost. In addition, the conventional filler packed in the hollow part of the hollow metal panel has an internal stress in the process of hardening and increasing the strength of the concrete filler, or the shrinkage due to the temperature change after hardening. And the like, and the filling material is constrained by a metal plate around it, there is no escape route for those accumulated stresses, and this is a cause of the squealing of energy generated as sound.

する。As a filling material for filling the hollow portion, a mixture of a recycled material of glass waste material obtained by crushing and molding used bottles, a material obtained by crushing styrofoam, and cement is used. Since glass is made from raw materials such as sand, soda ash, and limestone, when it comes to manufacturing glass products with new materials, it is of course necessary to quarry those materials, and in addition to the transportation means, it greatly affects the surrounding environment. Had a great influence. Further, since glass is a material that cannot be biodegraded, glass that is not reused after use needs to be landfilled. In the present invention, a waste glass material is used among the above-mentioned glasses, and the influence on the natural environment can be avoided. Traditionally, glass tableware, plate glass, various used bottles, etc. are cullet (broken glass) as glass waste materials.
However, the use of cullet, which is difficult to color-code, is limited, and many glass wastes of this type were discarded as they were. The present invention is most suitable for use as an aggregate because it is a use application in which the color of cullet is not particularly required to be sorted. In the present invention, the cullet obtained by further crushing is used as an aggregate.

る。As the Styrofoam, used Styrofoam molded products used for various cushioning materials, packaging materials, fish boxes, food trays, heat insulating materials for construction, etc. are crushed by a crusher or the like. The crushed particle size is about 1 to 3 mm. The particle size is not limited to the above and may be larger. Since the styrofoam is extremely lightweight, it may rise when mixed with cement. Also, there was a concern that it would rise up during the mixing work. Therefore, in order to prevent the floating and the like, the periphery of the styrofoam is coated in advance. As a coating means, the surface of styrofoam crushed particles is previously coated with cement paste. The fineness of cement is about 300
Since it is 0 to 3500 cm 2 / g, it is possible to coat the entire outer peripheral surface of the Styrofoam with the cement paste by mixing cement and water into the Styrofoam crushed particles and mixing them with a mixer or the like. As the other coating material, materials such as sand, stone powder, gypsum, and water glass can be adopted. Even if the entire outer peripheral surface of the Styrofoam is coated, its specific gravity is about 0, 3 to 0, 5.

である。Portland cement is usually used as the cement, but fly ash cement is most preferably used. Fly ash cement is a fine powder that collects fine particles of ash contained in the exhaust gas from a pulverized coal combustion boiler of a thermal power plant with a Cottrell dust collector, and a fly with a smooth surface. Since ash is used as a raw material, the workability is good, the long-term strength is large, the heat of hydration is low, and the drying shrinkage is small, and it is suitable as a material for filling the hollow portion of the hollow metal material as in the present invention. A filler for a hollow metal OA floor panel can be obtained by mixing water with the above glass waste material, used styrofoam crushed particles, and cement. A specific mixing ratio of the above materials is, by volume, a mixture of about 50% glass waste material, about 30% styrofoam and about 20% cement. The OA floor panel filled with the above-mentioned filler has a weight of about 7.0 kg in a panel unit of about 50 cm square and about 25 mm thick. Further, it has become possible to reduce the amount of cement as compared with the conventional OA floor panel. Further, it is also effective to mix a surfactant such as an AE agent in order to improve the fluidity when filling the hollow portion.

から得ることが出来ることに成る。Example 2 In Example 1 above, fly ash cement was used as cement, but in this Example, ecocement using municipal waste incineration ash as a raw material for cement is used instead of the cement. Since the municipal incineration ash contains about 2% of chlorine, it easily corrodes the reinforcing bar, so its use is limited. This eco-cement can be adopted in the present invention. When this chlorine is contained, the metal plate is not corroded by coating the metal plate. Further, in recent years, a technique has been developed in which crushed municipal waste is acidified with sulfuric acid and dechlorinated by waste heat (200 to 300 ° C) of a cement kiln. In this case, since chlorine is removed, the metal plate will not be corroded even if the cement and the metal plate come into direct contact with each other. The hollow metal OA floor panel filler can be obtained by mixing the eco-cement and water in the waste glass material and the styrofoam shown in Example 1 above. A specific mixing ratio of the above materials is, by volume ratio, a mixture of about 50% of waste glass material, about 30% of used styrofoam and about 20% of ecocement. Therefore, the second embodiment
In this case, all materials can be obtained from recycled materials as fillers.

Further, the entire periphery of the styrofoam is coated. As the cement, in addition to ordinary Portland cement, fly ash cement or ecocement can be used. The specific mixing ratio of the above materials is, by volume, about 60% to 70% of used Styrofoam and about 30% to 4 of cement.

It is possible to provide an OA floor panel which is excellent in terms of protection of the natural environment. In addition, the OA floor panel 1 is lighter than the conventional metal OA floor panel containing the same type of filler, and provides a member that is easy to handle for transportation, construction, or maintenance after laying the OA floor panel. It became possible to do. Further, it is lighter than the conventional OA floor panel, but since the OA floor panel is composed of the hollow metal plate and the mixture of the aggregate and the cement filled in the hollow portion, the predetermined weight is Since the space can be secured and the inside of the hollow is filled with the filling material, it is possible to obtain an OA floor panel excellent in walking feeling.

The floor panel generated noise due to the concrete-based filler sealed in the hollow part of the metal plate, but the one of the present invention adopts elastic Styrofoam as the aggregate and the filling. By reducing the proportion of cement in the total material, the amount of displacement such as strain caused by shrinkage of concrete due to drying or temperature change etc. was reduced, and the strain etc. was expanded by styrofoam. The sound was eliminated by absorbing it. Furthermore, since the expanded polystyrene particles have an air layer inside, they are excellent in heat insulating properties, soundproofing, and vibration damping properties, and as a result, the entire OA floor panel 1 containing the filler is also heat insulating properties, and from various devices. It has excellent soundproofing / vibrationproofing against generated sounds or walking sounds. Needless to say, the filled OA floor panel 1 of the present invention has both noncombustibility and rigidity.
