Description

Floor board using bamboo {floor board using bemboo}

The present invention relates to the field of floorboards used as indoor flooring, and more specifically, by attaching bamboo to each of the upper and lower parts by interposing ordinary wood between them to maintain high strength while reducing material costs. Together with the surface that is seen from the outside, it relates to floorboards made of bamboo, which make beautiful wood texture unique to bamboo appear.

In general, floorboards are used as floors of living rooms, such as apartments or detached houses, as well as indoor floors of offices. During construction, the floorboards are assembled in a length and width direction onto the floor to have a mosaic arrangement as a whole.

In recent years, due to the high quality of apartments and detached houses, the interest in indoor interiors has increased, and most of them use natural-friendly floorboards as flooring materials when constructing living rooms or floors. In addition, the development of related technologies is also in progress.

First, the conventional floorboard materials will be described in detail.

One embodiment of the conventional floorboard material is made of a single united tree, the other embodiment is made by adhering a pattern plate made by turning the wood thinly on the upper surface of the plywood, the floorboard material of the conventional embodiment As described, there are several problems because the whole consists of a single tree.

In other words, the wood used as floorboard is a special species (strong maple, beech, etc.) that is strong, grainy, and calm in color, and has to be received for several decades. Price is soaring when supply and demand are imbalanced. This is happening, due to various reasons that the non-commercial part like the knot part of the whole wood takes up a large part, the raw material cost is increased, and as the product price rises, it is not popularized and only used by some rich people. If the thickness of the floorboard material is a little thin to reduce the cost, when the wood is dried after construction, the whole property is the same and has the same bending property in the same direction. In order to make the whole thickness thicker It is to have a problem (such as weight of the material cost increase and weight increase).

In view of various problems of the above-described embodiment, a floor board material which is very popular at a low price is provided in another embodiment, and the floor board material of another embodiment is constructed by bonding a thin plate turned on to a low-cost plywood. In the state, only the pattern plate is displayed to the outside, so that the visual impression of the user is like a floorboard made of a single expensive wood, as in one embodiment, which can produce a low price product by reducing raw material costs. Of course, the plywood, which is one of the components, is bent to one side by drying in the process of use after construction, even though the overall thickness is not thicker than necessary, considering that a plurality of sheets of thinly lit sheets are irregularly bonded in various directions. This does not happen and is popularly used.

Then, the floor board member of another conventional embodiment will be described in detail with reference to FIGS. 2 to 4 as follows.

There is a rectangular plywood (1) having a suitable size, the insertion projections (2) are formed on one side of the long side and one short side of the plywood (1) while the other side of the long side and the other side of the short side for assembly An insertion groove 3 is formed, and a thin plate-like pattern plate 4 turned on with a thin thickness is adhered to the upper surface of the plywood 1, and a UV coating material or a urethane coating material is attached to the upper surface of the pattern plate. The surface protective layer 5 is formed by the application of.

In addition, a plurality of concave grooves 6 are formed on the bottom surface of the plywood 1 so as to form a checkerboard shape while crossing in the horizontal and vertical directions, which is an adhesive material for fixing the floorboard material when it is installed on the floor surface. To enter the recess groove to improve the fixing force, it does not necessarily need to be formed.

Referring to the manufacturing process of the floorboard according to another conventional embodiment configured as described above in more detail as follows.

While obtaining a plywood 1 of a suitable size in the form of a rectangular plate that is 6 to 8 mm in thickness and about 90 cm in length and about 8 cm in width, the thickness is about 1 mm apart from the plywood. The length and width are obtained by processing the patterned plate 4 having the same size as the plywood 1, respectively, and then forming the insertion protrusions 2 on one side of the plywood 1 and one side of the side of the plywood 1, and the other side of the other side. The insertion groove 3 is formed at the side and the other short side.

Then, after applying the adhesive to the upper surface of the plywood (1) and then lightly put the pattern plate (4) over the adhesive, it is pressurized and heated for a predetermined time by a heat press for the pattern plate (4) by the adhesive It is bonded to the plywood 1.

Subsequently, the top surface of the pattern plate 4 is smoothly processed using a sender, and then the UV coated or urethane coating agent is applied to the coated surface several times by roll coating, followed by drying. Floorboard material of the same structure is manufactured.

On the other hand, the floor board material manufactured by the above process may form a plurality of recessed grooves 6 to form a checkerboard shape while crossing in the horizontal and vertical directions to the bottom surface of the plywood 1, which is the floor board material manufactured In order to allow the adhesive force (epoxy, etc.) to fix the floorboard material to the concave groove when the construction to improve the fixing force, a plurality of concave groove (6) in the lower surface of the plywood (1) Since the work to be formed is determined in consideration of the convenience of the worker, it is not necessary to fix it in any particular order, but in the preferred order, it is performed immediately after the plywood 1 is provided or the pattern plate 4 It is contemplated that this should be done immediately after forming the surface protective layer 5 as the upper surface.

However, such a floorboard is conventional in the structure that is bonded to the pattern plate (4) turned on with a thin thickness on the upper surface of the plywood (1) is inexpensive in terms of price, but long-term use, the pattern plate is often peeled off partly maintenance In addition, there are problems that cost a lot of money, and in case of partial repair, the color of the part does not match well with other parts (discoloration or color difference), and thus there is a problem that is unsightly.

In addition, most floorboards produced so far have to be limited to patterns placed on wood and pattern boards. From the user's point of view, almost the same pattern is visually repeated in any house or office. There was also a problem that the user's product preferences are falling gradually to feel empirical.

The present invention is devised to solve the above-mentioned problems, the surface of the bamboo is a relatively low price by processing the side of the bamboo as a combination of the other wood with better cushioning power than bamboo and the surface is strong and its Its purpose is to make the distinction from existing products by expressing the bark unique to bamboo on the surface.

Insertion protrusion and the middle is formed so as to protrude outward from the lower bamboo plate used for assembly It is achieved by providing a floorboard material using bamboo, which is formed on the other long side and the other short side of the other side of the wood board to enter inwardly than the upper and lower bamboo boards, and comprises an insertion groove used for assembly with the insertion protrusion. You can do it.

Hereinafter, the present invention will be described in detail with reference to Examples.

4 is a perspective view showing a part of the floor board material using the bamboo of the present invention, Figure 5 is a longitudinal cross-sectional view showing the floor board material using the bamboo of the present invention, the floor board material using the bamboo of the present invention, Intermediate wooden board (11) made of a single rectangular plate shape made of wood material having better cushioning power than bamboo, and divided into a plurality of bamboo workpieces to have the same length as the intermediate wooden board (11) The upper bamboo board 12 is bonded to the upper surface of the longitudinal direction and is also bonded to each other in a horizontal state along the width direction to form a flat plate as a whole, a plurality of bamboo to have the same length as the intermediate wooden board 11 It is divided into workpieces and bonded to the lower surface of the intermediate wooden board 11 in the longitudinal direction, and in contact with each other horizontally along the width direction. The lower bamboo plate 13, which forms a flat plate as a whole, and is formed to protrude outward from the upper and lower bamboo plates 12 and 13 on one side of the middle and one side of the middle wooden board 11, The insertion protrusion 14 and the intermediate wooden board 11 to be used are formed to enter inwards from the upper and lower bamboo boards 12 and 13 on the other long side and the other short side of the other side. Insert groove 15 used for assembly together, and is formed as a UV coating material or a urethane coating material is applied to the upper surface of the upper bamboo board 12 is composed of a surface protection layer 16 to protect the surface .

In addition, a plurality of concave grooves 17 are formed on the lower surface of the lower bamboo board 13 to form a checkerboard shape while crossing in the horizontal and vertical directions, which is an adhesive material for fixing the floorboard material when it is installed on the floor. In order to enter the concave groove 17 to improve the fixing force.

In the construction of the floorboard material using the above-described inventive bamboo, the middle wooden board 11 between the upper bamboo board 12 and the lower bamboo board 13 is the wood texture of the upper and lower bamboo boards 12, 13 Cross to achieve the opposite direction of the wood, so that even after shrinkage and expansion depending on the surrounding conditions in the process of use does not cause bending in one direction, the middle wooden board 11 and the upper, lower bamboo board Although the wood grains of (12) and (13) do not necessarily cross each other, it is understood that warp does not easily occur during use because the general wood and bamboo have different properties.

Meanwhile, the middle wood pieces 11 between the upper and lower bamboo plates 12 and 13 should have a better cushioning force than the upper and lower bamboo plates 12 and 13, and the upper and lower bamboo plates The plate (12) (13) is due to the nature of the material, the cell is dense and very strong strength, sensitive to humidity and shrinkage and expansion deviation is severe, so to compensate for this, as well as to provide a pressing force in the process of use In order to sufficiently absorb and secure buffering force, the intermediate wood piece 11 is preferably made of paulownia wood, which is considerably superior in cushioning force to other wood pieces.

Referring to the manufacturing process of the floorboard according to the embodiment of the present invention of such a structure in more detail as follows.

2 ~ 3 year old bamboo, which is about 90cm in length, is split in the lengthwise direction and provided with several bamboo circular pieces. Then, the outer surface and inner surface parts of each of the bamboo circular pieces are cut horizontally, and then about 3 to 4 mm It is provided with a plurality of bamboo pieces having a thickness and flat on both sides, and after the plurality of bamboo pieces are provided, each of the provided bamboo pieces are laminated by a height of about 8 cm, and the opposite sides are used as an adhesive. In order to integrate each inner piece of wood by bonding, in order to integrate each inner piece of wood by bonding, the surface to be bonded (the bamboo processing piece which is located at the bottom of the drawing is the top surface and the topmost bamboo is placed on the drawing) The workpiece is a bottom surface, and the remaining bamboo workpieces in the drawing are top and bottom surfaces, respectively, and then the adhesive is applied. Laminated to each bamboo processing side to be in contact with each other and then pressed for a predetermined time to heat them by a press machine, must be heated can be understood.

In the above process, in order to provide a plurality of bamboo workpieces with flat surfaces on both sides, cutting the outer surface portion and the inner surface portion of each original bamboo piece in a horizontal state, since the bamboo is a hollow cylinder having a node, the cylindrical bamboo having the node The original bamboo after cutting is slightly bent, but has the surface and inner surface as well as the node. If used immediately without finishing, the surface of the surface including the node is exposed to the outside, so the product quality is deteriorated. Because it is curved, it breaks easily under pressure.

Subsequently, when the bamboo workpieces stacked in a unified state are repeatedly cut by a cutter to have a thickness of about 3 mm, several bamboo workpieces are bonded to each other in a horizontal state and have an appropriate size to form a rectangular plate (thickness is about 3 mm). , A length of approximately 90 cm, a width of about 8 cm) is obtained a plurality of bamboo plates, the process to obtain the bamboo plate is well shown in FIG.

In addition to obtaining a bamboo board by the above process to process a wood having a better cushioning power than bamboo and having the same specifications as the bamboo board while the middle wood board 11 is arranged in the width direction crossing the bamboo board 11 Get

When the bamboo board and the intermediate wooden board 11 is obtained in this way, the adhesive is applied to one surface of the bamboo board to be in contact with the intermediate wooden board together with the adhesive on the upper and lower surfaces of the provided intermediate wooden board. After application, the intermediate wooden boards 11 are sandwiched between the upper and lower surfaces of the intermediate wooden boards 11, and then temporarily bonded to each other by pressing and heating them for a predetermined time by a heat press. An upper bamboo plate 12 is provided as an upper surface, and a lower bamboo plate 13 is provided as a lower surface of the intermediate wooden board 11. The middle wood is a bamboo board to provide the upper bamboo board 12. One side long side of the middle wooden board 11 when bonding the bamboo board to the lower surface of the middle wooden board 11 to bond to the upper surface of the board 11 and to provide a lower bamboo board (13) One side short side is upper and lower When the upper and lower bamboo boards 12 and 13 are staggered with respect to the middle wood board 11 so as to protrude outward from the wood boards 12 and 13 to the long side and the short side, the protruding portion is inserted into the protrusion 14. Of course, the other one of the long side and the other side of the other side of the middle wooden board 11, the upper and lower bamboo boards 12, 13, so as to enter inwards than the middle wooden board 11, When the lower bamboo boards 12 and 13 are staggered to the long side and the short side, the recessed portion forms the insertion groove 15.

Thereafter, the upper surface of the upper bamboo plate 12 is smoothly processed using a sender, and then the UV coated or urethane coating is applied to the coated surface several times by roll coating, followed by drying. Floorboard material using a bamboo according to the embodiment of the present invention as shown in 5 is completed.

On the other hand, in the floorboard material using the bamboo produced by the above process to form a plurality of recessed grooves 17 to form a checkerboard shape while crossing in the horizontal and vertical direction to the lower surface of the lower bamboo board 13, which is manufactured When the floorboard material is installed on the floor surface, the adhesive material (epoxy, etc.) for fixing the floorboard material enters into the recess groove so that the fixing force is improved, and a plurality of lower surfaces of the lower bamboo plate 13 are provided. Work to form the two recessed grooves 17 is not necessary to be fixed in any particular order because the order is determined in consideration of the operator's convenience, but in the preferred order the lower bamboo on the lower surface of the middle wooden board (11) Immediately after the plate 13 is provided or immediately after the surface protection layer 16 is formed on the upper surface of the upper bamboo plate 12. Is thought that the.

In the present invention described above, it is preferable that the middle wooden board 11 made of wood having a better cushioning power than bamboo is made of paulownia wood. This is because if the pressing force is sufficiently absorbed to secure the buffering force, the bending force is prevented by elastically canceling the bending force for the cushioning force.

Therefore, the floorboard material using the bamboo of the present invention uses a relatively inexpensive bamboo and other wood having a better cushioning force than the bamboo, so that the bamboo is displayed on the surface of the upper surface, and the surface is strong and its pattern is general. As it has a unique node that can not be seen in trees, it is differentiated by breaking away from the conventional stereotypes, which leads to the high quality of the product, which increases the added value.

In addition, due to the harmony of bamboo and wood with a better cushioning force than the bamboo, even if used for a long time does not cause any warping, as well as the surface does not easily scratch, there is also an effect of increasing the image of the product by the consumer.
