Benefits of technology

[0016] The present invention has been made in an effort to provide a floor panel for a raised floor system having advantages of slim thickness, high stiffness, and light weight so as to provide a stable feel when walking and a wide spacing of pedestals.

Problems solved by technology

Such a wave causes an uneasy feeling to people who are accustomed to a hard and rigid floor, such as a cement mortar floor.
However, when the spacing between pedestals is greater (that is, when each floor panel is larger), stiffness of the floor panels for a raised floor system is decreased and the wave phenomenon caused by walking, as well as a sagging problem, may occur.
In addition, conventional floor panels are 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 the pedestals.
This may cause a disadvantage in that a height of the raised floor system is limited.
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.
However, in this case, installation cost is increased since the number of pedestals required is increased.
A particle board is used for commercial and residential raised floor systems since it has advantages of having enhanced strength and manufacturing ease compared to its low price, but it also has drawbacks in that a size and strength thereof may be changed and deteriorated by being exposed to moisture.
Although there is a particle board formed with a waterproof sheet, it is expensive and has only a little increase of waterproof performance, about 40%.
Further, most conventional waterproof coating liquid products are for blocking moisture in cement floors, outer surfaces of a building, and underground structures, and there is no product among conventional waterproof coating liquid products for a waterproof coating material for a particle board.

[0107] Furthermore, by an application of a high stiffness floor panel 20, spacing between the pedestals 30 can be enhanced up to 800×1,200 mm for a raised floor system as shown in FIG. 1. Performance of reducing a floor impact noise (for example, according to a measurement method of KS F 2810-2 and a rating method of KS F 2863-2 of the Korean Standard) is 45 dB(A), which is a satisfactory value.

[0108] In addition, in the case that the waterproof composition is formed in accordance with Table 2 and the particle board is coated by the formed waterproof composition, an expansion rate of absorption thickness is decreased from 10.13% before coating to 4.34% after coating, that is, water tolerance has been increased.

Abstract

A floor panel for a raised floor system is provided, where the floor panel includes a plate member with at least one longitudinal groove and a reinforcing member at least a portion of which is inserted into the longitudinal groove. The longitudinal groove is formed on the plate member of the floor panel for a raised floor system, and a stick type reinforcing member and/or a plate type reinforcing member is inserted into the longitudinal groove. Thereby, a thickness of the floor panel can be reduced and at the same time high stiffness and light weight of the floor panel can be achieved, and so a better walking feeling can be obtained and wider spacing of pedestals can be achieved. By coating the plate with a waterproof composition, it is possible to overcome drawbacks of a size and strength thereof being changed and deteriorated by being exposed to moisture.

Description

CROSS-REFERENCE TO RELATED APPLICATION [0001] This application claims priority to and the benefit of Korean Patent Application No. 10-2005-0015683 filed in the Korean Intellectual Property Office on Feb. 25, 2005, the entire contents of which are incorporated herein by reference. BACKGROUND OF THE INVENTION [0002] (a) Field of the Invention [0003] The present invention relates to 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 as well as small thickness by inserting a reinforcing member into a longitudinal groove of a plate type member. [0004] (b) Description of the Related Art [0005] A typical interior room of a house, an office, a computer room, and a factory for using IT-related electronic products, etc., therein, is applied with a raised floor system in which, for accommodating cables, pipes, etc., floor panels are arranged on equally spaced pedestals such that an un...
