Description

UPPER BOARD AND RAISED ACCESS FLOORS SYSTEM WITH THE SAME}

The present invention relates to a double floor system, and more particularly, to a top plate having improved strength and reduced thickness and a double floor system having the top plate.

Due to the advantages of utilizing the lower space, the double-floor system, which has long been used in commercial applications such as computer rooms, is usually made of a top plate, a support plate for supporting the top plate, and the support plate is screwed to the support plate, A leveling bolt for leveling the top plate, and a support rubber provided at the bottom of the leveling bolt.

However, the conventional double floor system does not effectively suppress various problems such as interlayer noise (light floor impact sound and / or heavy floor impact sound) reduction performance and high load generated in the ondol heating layer.

Therefore, the above-mentioned double floor system is not applied to apartment houses such as apartments, that is, residential so far.

Therefore, in order to apply the above-mentioned double-floor system to a multi-family house, the development of a high strength top plate must be inevitably preceded.

In addition, the top plate is also required to minimize the thickness to ensure a sufficient lower space.

Therefore, conventionally, such as particle board (PB: Particle Board), plywood (Plywood), MDF (Medium Density Fiberboard), HDF (High Density Fiberboard), OSB (Oriented Standard Board), wood system, wood cement board, The upper plate is composed of a plate member made of a single material such as inorganic cement, synthetic resin, steel or aluminum, or a composite material using two or more materials such as wood and aluminum at the same time. Particle board is mainly used as a plate member in consideration of stiffness and easy processing.

Here, the particle board is a plate-like product having a density of 500 to 900 kg / m ³ by molding and hot pressing by adding a synthetic resin adhesive to particles of wood and other plant fibers, that is, cutting pieces or crushed pieces.

By the way, the top plate manufactured using the particle board has a problem that the lower space is reduced when the thickness of the top plate is increased to improve the strength, the strength is lowered when the thickness is reduced to increase the lower space.

In order to solve this problem, the top plate has been conventionally configured with a sandwich structure including an upper plate and a lower plate and a reinforcing material disposed between the plates.

As an example of a top plate formed of a sandwich structure, EP-A-0108904 discloses a top plate having a reinforcement formed of a bottle-like membrane structure.

By the way, the conventional top plate having a reinforcement formed of a screen-like membrane structure has to be fixed to the top plate or the bottom plate to install a plurality of reinforcement, and each reinforcement must be arranged at the same interval during installation work, etc. There is a problem that the deterioration of the properties, and also takes a lot of time for the top plate assembly work.

Therefore, as mentioned above, the conventional double-floor system having a top plate is not applied to a common house such as an apartment, that is, residential.

Accordingly, the present invention has an object to provide a top plate with improved strength and reduced thickness.

Another object of the present invention is to provide a double-floor system that can be applied to a multi-family house by providing the top plate.

The first object of the present invention described above,

In an embodiment of the present invention, the reinforcing sheet may be made of any one of a plurality of compressed paper layers, a plurality of damping sheet layers, or a plurality of vinyl sheet layers.

The reinforcing sheet is formed in the same size as the empty space formed by the reinforcing ribs, and at least one of the upper plate and the lower plate is disposed with an adhesive tape for fixing the reinforcing sheet. Of course, the reinforcing ribs can also be fixed to the adhesive tape. In this case, the reinforcing rib and the reinforcing sheet are preferably fixed to the same substrate.

In addition, it is also possible to use an adhesive or bonding means (nail, screw, etc.) instead of the adhesive tape.

The top plate of such a configuration has an effect of reducing the thickness of the top plate because the strength is increased by the reinforcing ribs and the reinforcing sheet.

Furthermore, since the top plate assembling work is completed by adhering a reinforcing sheet having the same size as that of the empty space to the adhesive tape, the assembling workability is improved as compared with the conventional case using the reinforcing material having a screen-like film structure.

The double bottom system having a top plate of such a configuration further includes a support for supporting the top plate, which is installed between the support plate for supporting the top plate, a leveling bolt screwed to a nut installed on the support plate, and between the leveling bolt and the slab. It includes support rubber.
