Description

Raised floor panel

The present invention relates to a raised floor panel, and more particularly to a panel formed by connecting upper and middle plates and middle and lower plates of a panel, which is not only lightweight and easy to set, but can be reused to reduce the environment. It is a movable floor panel which is polluted and which forms a through hole which penetrates at a certain interval between the upper plate and the intermediate plate, and forms a sound absorbing groove in the intermediate plate, thereby reducing the resonance phenomenon.

In general, in an office such as an intelligent building with an office automation facility, it is widely used to improve the efficiency of wiring, such as electric wires and communication lines used in various electric appliances and electronic devices, in consideration of indoor ventilation and aesthetics. By setting the indoor floor of the building as a two-story raised floor panel, by burying the line arrangement under the ground, it is possible to improve the simplification of the room and the office environment against static electricity.

The movable floor panel is mostly formed to have a certain size, is installed on the supporting members spaced apart from each other on the ground, and is connected to each other and can be divided into a cement mortar and a PB (Particle Board) plywood. The formed panel and the metal panel in which the hollow portion is formed inside to overlap the metal sheet with a certain thickness.

Here, the PB plywood is a product obtained by mixing a wood chip with a binder and using hot pressing, and is also called a chip board.

The metal panel filled with the cement mortar has a certain weight due to the filling of the cement mortar, which is not only difficult to handle and set up, but also causes a safety accident due to excessive load.

Moreover, the metal panel filled with the PB plywood is lighter in weight than the metal panel filled with the cement mortar, but the wood pulverized material is mixed with the binder, and the heat is utilized. It is made into a product by pressing, so there is a problem of being afraid of moisture, and it is more likely to be damaged by external impact than when it is expanded and dried after being wet.

In addition, when the metal panel filled with the cement mortar and the PB plywood is placed on the ground in order, the metal panel must be cut in a space smaller than the metal panel, but the metal panel is cut off. At the same time, there will be problems of scattering dust from cement mortar or PB plywood and causing pollution of the surrounding environment.

Furthermore, when the metal panel filled with the cement mortar and the PB plywood is disposed of, it is difficult to separate the cement mortar and the PB plywood from the metal panel, and it is impossible to reuse, and the metal panel is filled with the cement mortar and If the PB plywood is discarded, it will also cause environmental pollution.

At the same time, the metal panel formed by forming the hollow portion and overlapping the metal sheet is lighter in weight because the interior is hollow, although it is easier to set than the metal panel filled with the cement mortar and the PB plywood, and the metal panel is not filled. Cement mortar and PB plywood can eliminate the environmental pollution caused by the filler filled in the metal panel, but due to the impact caused by walking, there will be a sound echo caused by the resonance in the closed hollow or The problem of vibration.

In addition, although the respective corners of the metal panel are horizontally fixedly mounted on the upper portion of the support table provided on the ground to maintain a firm support state, but are connected in a state in which the respective sides of the metal panel are closely attached to each other. In the case of the edge of the metal panel, the central portion of the edge of the metal panel is deformed downward by the two corners as a base point, so that a height difference is generated, which not only causes a safety accident, but also allows the user to lower the product. The issue of trust.
