昭59-55952号,実開昭61-52028号)。2. Description of the Related Art Floor panels include aluminum, steel, inorganic materials such as concrete, synthetic resin, and wood. These are formed in a rectangular shape and are laid on the floor directly or in a state of being supported at a predetermined height by support legs. The free access floor was developed for the purpose of underfloor wiring in the computer room, and is now widely used as an OA floor in general offices such as intelligent buildings. 200 for floorboard
A load of about 500 kg is applied. The steel panel generally has a hollow structure in which the top and bottom constituent members are integrated by welding or clinch bonding (for example, JP-A-59-55952 and JP-A-61-52028).

ことも特公平5-43022号で提案している。The floor panel generates a walking sound due to vibrations during walking on the floor, which is amplified, but concrete is poured into the entire hollow part of the panel to reduce the noise and to reinforce the top plate. There is something. In particular, the applicant of the present invention has previously proposed centrifugal injection in JP-A-64-71969, and also proposes to reduce the weight by using inorganic hollow particles as an injection material in Japanese Patent Publication No. 5-43022. .

の配合に制約がある。Concrete-injected steel floor panels are used to inject concrete into pre-bonded floor panels later.
This requires a large-scale production facility and requires a high level of skill and management to completely inject. Since it is injected from a smaller hole, the fluidity becomes a problem, and there is a restriction on the composition of the material to be injected.
