CROSS-REFERENCE TO RELATED APPLICATION [0001] This application claims priority to and the benefit of Korean Utility Model Application 20-2004-0020793 filed in the Korean Intellectual Property Office on Jul. 21, 2004, the entire content of which is incorporated herein by reference. BACKGROUND OF THE INVENTION [0002] (a) Field of the Invention [0003] The present invention relates a floor panel for a raised dry-floor system. More particularly, the present invention relates to a floor panel for a raised floor system having enhanced strength by adopting an aluminum reinforcement member of a rib structure or a hollow space in various schemes. [0004] (b) Description of the Related Art [0005] A typical interior room of a house, an office, a computer room, a factory for IT-related electronic products, etc., is applied with a raised floor system 10 in which, for accommodating cables, pipes, etc., floor panels 20 are arranged on equally spaced pedestals 30 as shown in FIG. 2 such that an under-floor space corresponding to a height and spacing of the pedestals may become available. [0006] A typical raised floor system scheme usually involves a relatively heavy material such as a steel support and mineral panel such that it may endure a heavy load. In addition, installation speed is not sufficient, and the speed and quality of the installation depends much on the skill of a worker. [0007] In the case of Japan, the raised floor system is applied to apartment houses. However, the principal purpose is for providing room for under-floor pipes and reducing light floor impact noises. That is, the reduction capability of heavy floor impact noises is minimal, and depending on the structure of the building, the reduction of impact noise is sometimes deteriorated. Further, soft rubber is adopted in order to maximize the reduction of the floor impact noise, which causes a wave when a person walks on the raised floor system. Such a wave causes an uneasy feeling to people who are accustomed to a hard and rigid floor such as a cement mortar. [0008] According to a conventional Japanese sound insulation raised dry-floor system, a plurality of pedestals are arranged on a concrete slab floor, and a plurality of floor panels are laid on the pedestals. In this case, when spacing between pedestals is greater (i.e., when the number of pedestals is smaller), the number of trials for horizontal leveling is reduced, installation speed is enhanced, and a cost for the pedestals is reduced. However, when the spacing between pedestals is greater (that is, when each floor panel is larger), stiffness of the floor panel for a raised floor system is decreased and the wave phenomenon caused by walking and a sagging problem may occur. [0009] Due to such drawbacks, the spacing between pedestals for a conventional raised floor system (i.e., a size of the floor panel) has been realized as 600.times.455 mm, at best. [0010] In addition, the conventional floor panel is usually made of a single integral plate of particle board such that it may have a drawback of low absorption of floor impact noise. Furthermore, the high weight of such a floor panel produces a big load on pedestals. [0011] The feel of walking is one of the important criteria for a material for a raised floor system. When the stiffness of a floor panel is insufficient, the floor panel may wave due to walking thereon, and a person may feel uneasy or uncomfortable. In order to prevent such a phenomenon, the spacing between pedestals may be decreased. However, in this case, installation cost is increased since the number of pedestals required is increased. [0012] The above information disclosed in this Background section is only for enhancement of understanding of the background of the invention, and therefore it may contain information that does not form the prior art that is already known in this country to a person or ordinary skill in the art. SUMMARY OF THE INVENTION [0013] The present invention has been made in an effort to provide floor panels for a raised floor system having advantages of high stiffness and light weight so as to provide a stable feel when walking and wide spacing of pedestals. [0014] An exemplary floor panel for a raised floor system according to an exemplary embodiment of the present invention includes an upper plate, a lower plate, a reinforcement frame of a polygonal shape disposed between the upper and lower plates, and at least one aluminum reinforcement member disposed in the polygonal shape of the reinforcement frame. [0015] The reinforcement frame may be formed in the same sectional shape as the aluminum reinforcement member. [0016] The upper plate, the lower plate, and the reinforcement frame may be made of various materials, for example, a single material such as wood, a mineral material, a synthetic resin, steel, aluminum, or a compound material such as a combination of wood and aluminum. [0017] For example, the upper and lower plates may be made of various materials such as particle board, plywood, oriented strand board (OSB), or mineral board. [0018] For example, the reinforcement frame may be made of various materials such as aluminum, plywood, oriented strand board (OSB), or wood. When aluminum is used for the reinforcement frame, the floor panel may have better weight and stiffness since both the aluminum reinforcement member and the reinforcement frame are made of an aluminum material. [0019] For a light weight of the floor panel, at least one hollow space may be formed within at least one of the aluminum reinforcement member and the reinforcement frame along a length direction thereof. [0020] The at least one hollow space may be formed as a plurality by at least one rib formed in the aluminum reinforcement member. [0021] The at least one rib may include a wall member, a head formed at a top of the wall member and combined with the upper plate, and a leg formed at a bottom of the wall member and combined with the lower plate, wherein at least one of the head and the leg is formed in a triangular shape or a hemispherical shape that broadens when approaching a corresponding plate of the upper and lower plates from the wall member.
