Description

WATER PROOF REINFORCED FLOOR AND CLICK STRUCTURE THEREOF

Technical Field

[1] The present invention relates to a waterproof reinforced floor panel, and more particularly, to a waterproof reinforced floor panel, which includes extrudate members of a strong waterproof property bonded and fixed on both sides thereof and coated layers of a strong waterproof property formed on the top and bottom surfaces thereof, thereby imparting a high rigidity and a good waterproof property to mutually fit portions of the floor panels. Background Art

[2] Along with gentrification of the interior floor decoration, instead of a PVC floor covering, which has been used as a conventional floor decoration material, the demand for a floor decoration using wood is gradually increased. At the early stage, the floor decoration using wood mainly used high-class material timber, but was restrictively used to some high-class mansions since raw materials and construction costs were very expensive. So, a reinforced floor using inexpensive timber, for instance, waste timber remaining after processing of wood, instead of raw wood, was produced. However, there are several problems in that a supply of waste timber could not satisfy a demand of the waste timber since an amount of the produced waste timber was restricted, and in that the quality of the outward appearance was deteriorated since a large-sized timber plate was made in such a way as to bond small- sized timber pieces with one another.

[3] To solve the above problems, an attempt has been made to process a wood panel using sawdust, for instance, a high density fibreboard (hereinafter, called HDF) and a medium density fibreboard (hereinafter, called MDF), into a reinforced floor panel. FIG. 1 illustrates such an HDF for a reinforced floor. As shown in FIG. 1, the HDF for a reinforced floor includes a sheet paper 2 having a wood-grain pattern thereon and bonded on the surface of the HDF 1 to enhance quality of the outward appearance, and a concavo-convex portions having a concave groove 3 formed on one side thereof and a convex protrusion 4 formed on the other side thereof, so as to be fit to another HDF to form the reinforced floor. The concave groove and the convex protrusion may have one of various section forms in such a way that they can be forcedly fit with each other, and have mutually corresponding forms. The HDF for a reinforced floor is manufactured in the steps of bonding sheet paper on the HDF and forming the concavo- convex portion on the right and left sides thereof in a longitudinal direction using a working lathe.

[4] As described above, the floor panels, each of which has the concavo-convex portion formed at both sides thereof, are fit with each other to form the reinforced floor, but has a problem in that the concavo-convex portion formed at both sides thereof is weak in strength. So, it causes an increase in construction costs since the concavo-convex portion is broken during construction or when the floor panels are disassembled for transfer.

[5] Particularly, since the HDF panel manufactured by processing sawdust is susceptible, the mutually fit portions thereof are come off or damaged the surface of the floor becomes uneven and the floor has a prominence and depression portion, when water permeates into a gap while a user mops with a damp cloth or the HDF panel absorbs moisture.

[6] So, in the market, there is a continuous demand for reinforced floor panels, which has good rigidity and whose fit portions are not damaged. However, there is a problem in that thickness of the board becomes thicker or high-grade materials must be used to increase rigidity. In addition, there is another continuous demand for products having good durability due to high waterproof property even though water permeates into the gap during the use. Disclosure of Invention

Technical Problem

[7] Accordingly, it is an object of the present invention to provide a waterproof reinforced floor panel, whose fit portions have a high rigidity.

[8] It is another object of the present invention to provide a waterproof reinforced floor panel, which can have an even surface even though it is used for a long time since the mutually fit portions are not come off due to a good waterproof property and a low moisture absorption rate.

[9] It is a further object of the present invention to provide a waterproof reinforced floor panel, which uses an inexpensive HDF panel but has fit portions having a high rigidity and is low in moisture absorption rate, thereby providing the even surface even though it is used for a long time since the fit portions are not come off. Technical Solution

[10] To achieve the above objects, the present invention provides a waterproof reinforced floor panel including: a floor panel having a concavo-convex portion longitudinally formed on both sides thereof; a first extrudate member having a concavo- convex portion longitudinally formed on one side thereof to correspond to the concavo-convex portion of the floor panel and a first fit portion formed on the other side thereof, the concavo-convex portion of the first extrudate member being fit, bonded and fixed to the concavo-convex portion of the floor panel; a second extrudate member having a concavo-convex portion longitudinally formed on one side thereof to correspond to the concavo-convex portion of the floor panel and a second fit portion formed on the other side thereof to correspond to the fit portion of the first extrudate member, the concavo-convex portion of the second extrudate member portion being fit, bonded and fixed to the concavo-convex portion of the floor panel; and coated layers formed on the top and bottom surfaces of the floor panel and the extrudate members.

[11] The extrudate members may be constructed of a profile type using plastic or aluminum, and shut off moisture introduced to the right and left sides of the floor panel.

[12] The coated layers are formed on the top surfaces of the floor panel and the first and second extrudate members to prevent that moisture or water is infiltrated into a gap between the floor panel and the extrudate members. There is no special restriction as much as the coated layers can prevent moisture infiltrated into the upper and lower portions of the floor panel, but it is preferable that the upper coated layer is a wood- grain patterned sheet paper laminated or bonded on the extrudate members and the floor panel to give the feeling of natural wood. The lower coated layer is a melamine- coated layer formed on the extrudate members and the floor panel to prevent moisture transferred from the lower portion. The sheet paper may be a general melamine film for decoration, and may include a transparent overlay layer formed on the melamine film to enhance abrasion resistance, durability and UV blocking effect.

[13] The floor panel may be natural or processed panel of various forms, and preferably, an inexpensive panel, which is weak to moisture, for instance, a high density fibreboard (hereinafter, called HDF) and a medium density fibreboard (hereinafter, called MDF).

[14] In addition, the concavo-convex portions formed on both sides of the floor panel may be concave grooves or convex protrusions formed on both sides thereof, or a concave groove formed on one side thereof and a convex protrusion formed on the other side thereof.

[15] Furthermore, in another aspect of the present invention, the present invention provides a reinforced floor comprising waterproof reinforced panel comprising: a floor panel having concavo-convex portions longitudinally formed on both sides thereof; a first extrudate member having an concavo-convex portion longitudinally formed on one side thereof to correspond to the concavo-convex portion of the floor panel and a first fit portion formed on the other side thereof, the concavo-convex portion of the first extrudate member being fit, bonded and fixed to the concavo-convex portion of the floor panel; a second extrudate member having an concavo-convex portion longi- tudinally formed on one side thereof to correspond to the concavo-convex portion of the floor panel and a second fit portion formed on the other side thereof to correspond to the fit portion of the first extradate member, the concavo-convex portion of the second extrudate member portion being fit, bonded and fixed to the concavo-convex portion of the floor panel; and coated layers formed on the top and bottom surfaces of the floor panel and the extrudate members.

[16] In another aspect of the present invention, the present invention provides a fitting extrudate member including a concavo-convex portion longitudinally formed on one side thereof to correspond to the concavo-convex portion of the floor panel, and a fit portion formed on the other side thereof to be fit with other floor panel.

[17] Each of the extrudate members has the same thickness as the HDF floor panel, so that the top and bottom surfaces of a floor plate formed in such a way as to fit and bond the extrudate members to both sides of the floor panel are in one plane.

[18] The extrudate members are produced in an extrudate member die, cooled, and bonded to both sides of the floor panel.

[19] In the present invention, the floor panel is a waterproof floor panel. The coated layer formed on the surface of the floor panel and the surfaces of the extrudate members fit on both sides of the floor panel prevents absorption of water flowing from the upper and lower portions of the floor panel, and the extrudate members fit on both sides of the floor panel prevent absorption of water flowing from the sides of the floor panel, so that the floor panel having the waterproof property can be produced.

[20] The present invention is not to be restricted by the following embodiment, and it is to be appreciated that those skilled in the art can change or modify the embodiment without departing from the scope and spirit of the present invention.

[21] For instance, those skilled in the art can change or modify the quality of wood and the quality, length, width and thickness of the extrudate member type extrudate member without departing from the scope and spirit of the present invention.

[22] Therefore, the right scope of the present invention is not restricted by the scope of the embodiment but is restricted only by the appended claims and the technical idea of the present invention.

Advantageous Effects

[23] The floor panel for a floor decoration according to the present invention can prevent damages of fit portions thereof during construction or use since the fit portions consist of profile extrudate members of a high rigidity.

[24] In addition, the floor panel for the floor decoration is generally thin and safe in construction and use since rigidity of the weakest portion is reinforced. Moreover, the floor panel is more inexpensive in comparison with floor panels of the same principle and the same thickness, but allows a user to stably construct HDF timber, whose fit portions are weak due to their weak rigidity.

[25] Furthermore, the reinforced floor panel according to the present invention can be used for a long time and prevent that the concavo-convex portions are damaged or come off by moisture since the fit portions of the floor panel are extrudate members and the top and bottom surfaces of the floor panel are covered with waterproof coated layers to perfectly cut off moisture in all sides.
