Description

Furniture board and manufacturing method thereof {Furniture board and manufacturing process of the same}

The present invention relates to a furniture board and a manufacturing method thereof, and more particularly, to a light and easy-to-purchase bamboo as a raw material, and forming a coating layer, a lapping layer, and a reinforcing material on the raw material, thereby providing convenience and durability in manufacturing the raw material. And it relates to a furniture board and a method for manufacturing the same to improve durability.

Plywood, commonly referred to as plywood, refers to thinly cut raw wood, arranged so that it is orthogonal to the fiber direction, and then laminated.

As the plywood rotates around the center of the wood as an axis, the rotary method cuts the wood with a knife as if unfolding a paper scroll and the thin cut with a knife that moves up and down. The maximum width is up to the diameter of the wood, but beautiful wood grain is produced. After obtaining a veneer by a slicer method having the advantage of doing, as described above, the direction of the fibers of each veneer is orthogonal to each other and pressed using an adhesive such as casein, viscose, glutamine, etc. in a state in which multiple sheets are overlapped, thereby completing the getting plywood

Such plywood includes general plywood used for interior and exterior of houses, ceilings, walls, vehicles, furniture, musical instruments, etc., plywood for formwork used for curing concrete and industrial materials for construction, and phenolic resin or melamine on both sides of plywood for formwork sanded Tego plywood, which is a plywood impregnated with resin film, particle board made by molding small chips of raw wood before fiberization, and MDF used for furniture, musical instruments, molding materials, vehicles, and There are various types of plywood, such as core plywood that replaces the thick plate of general plywood, which is made by bonding the title and attaching veneer on it.

At this time, since the sink top plate or the desk top plate must be able to withstand a large load stably, there are many cases made of plywood. Generally, the plywood manufactured is thinner than the sink top plate or desk top plate, so the sink top plate or desk top plate In order to use it as a top plate, there is a disadvantage that a separate order production is required.

In addition, when the plywood is laid horizontally so that it can be used as a sink top plate or a desk top plate, the laminated surface is exposed to the front and rear and left and right sides, so there is a problem in that the appearance is not good.

In some cases, a separate sheet is attached to cover the laminated surface of the plywood, but in this case, the texture of the wood cannot be felt at all.

In addition, when water is absorbed in the laminated surfaces located on the front, rear and left and right sides, the absorbed water permeates between two adjacent veneer plates, and twisting deformation of each veneer easily occurs, and adhesion of the adhesive bonding the two adjacent veneer plates. There is a problem that the strength of the entire plywood is significantly reduced due to the release of the bond between the veneers due to the deterioration of the properties.

Of course, if the top plate of the sink or the top plate of the desk is made of one thick solid wood board, even if the side surface gets wet, deformation and strength reduction do not easily occur. has a problem.

As a solution to the above problems, Patent No. 10-1421682 of the present applicant has been proposed.

As shown in FIGS. 1 and 2, the furniture board and its manufacturing method disclosed in Patent No. 10-1421682 have a plywood structure in which a plurality of single boards are stacked, and an upper board 110 that is laid horizontally, and The outer plate 100 divided into one or more side plate parts 120 that are manufactured to extend horizontally from the edge of the upper plate part 110 and then bent 90 degrees downward, and a plurality of single plates It is formed of a laminated plywood structure, The inner wave 400 inserted into the space between the bottom surface of the upper plate part 110 and the inner surface of the side plate part 120 is included.

A bending groove 200 along the bending line of the side plate 120 is formed on the bottom surface of the point where the top plate 110 and the side plate 120 are connected, so when the side plate 120 is bent at 90 degrees. The inner surfaces of the bent grooves 200 are coupled so as to come into close contact with each other.

In addition, the bending groove 200 is formed in a V-groove shape having an interior angle of 90 degrees, and the bending groove 200 is formed on the side plate portion vertical surface 220 extending upward from the bottom surface of the side plate portion 120, and the top plate portion ( 110), an upper plate-side vertical surface 240 extending upward from the bottom surface, an upper plate-side horizontal surface 230 extending horizontally from an upper end of the top plate-side vertical surface 240 in a direction toward the side plate portion 120, and the side plate side It includes a pair of inclined surfaces 210 extending obliquely in a direction closer to each other from the end of the extension direction of the vertical surface 220 and the end of the extension direction of the upper plate-side horizontal surface 230 and meeting to form a right angle.

When the side plate portion 120 is bent at 90 degrees, the side plate side vertical surface 220 is in close contact with the top plate side horizontal surface 230, the pair of inclined surfaces 210 are in close contact with each other, and the top plate side vertical surface ( 240) includes a tape 300 adhered to the bottom surface of the side plate and attached to an upper surface at a point where the top plate part 110 and the side plate part 120 are connected.

Accordingly, by bending the thin plywood, the laminated surface is not exposed to the outside even though the thickness is thick, so that the durability against moisture is excellent and the feeling of raw wood can be given.

However, the manufacturing cost of the conventional furniture board is high, which increases the unit cost of products produced using the board as a material.

In addition, there is a problem that the conventional sheet material does not maintain smooth waterproofness.
