access floor

Abstract

The present invention relates to a raised floor. In this access floor, the upper plate and the lower plate of the board are respectively provided with through holes at predetermined intervals, so that the generation of noise caused by the resonance phenomenon can be prevented, and since the upper board, the middle board and the lower board are combined to form a board, Therefore, it is light in weight, easy to install, and can be reused, thereby reducing environmental pollution and improving economy.

Description

technical field [0001] The present invention relates to a raised floor, in particular to an upper plate and a lower plate with through holes at predetermined intervals, so that noise caused by resonance can be avoided, and since the upper plate and the middle plate Since it is combined with the lower board to form a board, it is light in weight, easy to install, and can be reused to reduce environmental pollution. Background technique [0002] In general, raised floors are widely used in offices such as smart buildings equipped with office automation facilities. This kind of raised floor improves the wiring efficiency of electric wires or communication lines, etc. used for various electrical / electronic equipment, and considers indoor ventilation and In order to improve the aesthetics, the indoor floor of the building is doubled. Since the wiring is buried in the ground, it can achieve the effects of simplifying the room and improving the office environment such as anti-stati...

Problems solved by technology

[0005] The metal plate filled with the cement mortar is heavy due to the filling of the cement mortar, so it is difficult to carry and install it, and there is a problem of causing a safety accident due to the application of an excessive load.

[0006] In addition, although the metal plate filled with the above-mentioned PB plywood is lighter than the metal plate filled with cement mortar, it has the ability to resist moisture because it is manufactured by hot pressing by mixing ground wood and adhesives. Weak problem, when it is expanded under the action of moisture and then dried, it is more likely to be damaged by external impact than before it is expanded under the action of moisture

[0007] And, in the process of placing the metal plates filled with the cement mortar and PB plywood sequentially on the ground, it is necessary to cut the metal plate in a space smaller than the size of the metal plate, but when cutting the metal plate, the cement mortar or PB plywood Dust will be generated on the surface and there is a problem of polluting the surrounding area

[0008] Moreover, when the metal plate filled with the cement mortar and PB plywood is intended to be discarded, it is difficult to recycle the cement mortar and PB plywood from the metal plate, and if the metal plate is filled with cement The state exhaust gas of mortar and PB plywood has the problem of polluting the environment

[0009] In addition, a metal plate that overlaps metal plates to form a hollow inside is lighter because it is hollow inside, so it is easier to install than a metal plate filled with cement mortar and PB plywood, and since cement mortar and PB plywood are not filled In the metal plate, it is possible to eliminate the environmental pollution caused by the filler filled in the metal plate, however, under the action of the impact transmitted when the pedestrian walks, a noticeable sound or tremor caused by the resonance phenomenon is generated in the hollow part, thereby There is a problem of resonance caused by noise
