These natural wooden boards have a disadvantage in that their original shape and texture are easily damaged by water and sunlight.

특히, 천연 목재판은 목재 데크와 같이 실외에 설치된 경우에는 방부처리를 하더라도 설치후 장기간이 지나면 수분과 햇볕에 의해 강도가 약해지면서 부패되어 쉽게 파손되거나 훼손되며 수축과 팽창이 빈번하게 발생하여 쉽게 변형되는 문제점이 있었다.In particular, when natural wood boards are installed outdoors, such as a wooden deck, even if they are preserved, their strength is weakened by moisture and sunlight after a long period of time after installation, and they are easily damaged or deteriorated due to frequent contraction and expansion. There was a problem.

이러한 천연 목재판이 가지는 단점을 보완하기 위해 합성 목재판이 개발되었는데, 합성 목재판은 목분과 합성수지와 혼합하여 고온 고압 상태에서 판형태로 성형하여 제작하는 것으로, 목재의 특징과 합성수지의 장점을 갖춘 것이지만 그 폐기시에 환경오염을 유발하는 문제점이 있었다.Synthetic wood boards were developed to compensate for the shortcomings of these natural wood boards. Synthetic wood boards are manufactured by mixing them with wood powder and synthetic resins and molding them into a plate shape under high temperature and high pressure conditions, but they have the characteristics of wood and the advantages of synthetic resins. There was a problem that caused environmental pollution during disposal.

도 1 내지 도 2는 본 발명에 따른 하이브리드 목재판을 보인 개략적인 도면들이다. 이에 도시된 바와 같이, 본 발명에 따른 하이브리드 목재판은 천연 목재판(10)과, 상기 천연 목재판(10)의 상면에 부착되는 베니어합판(20)과, 상기 베니어합판(20)의 상면에 부착되는 압축 목재판(30)을 포함한다.1 to 2 are schematic views showing a hybrid wooden board according to the present invention. As shown, the hybrid wood board according to the present invention includes a natural wood board 10, a veneer plywood 20 attached to the upper surface of the natural wood board 10, and an upper surface of the veneer plywood 20. It includes a compressed wood board 30 to be attached.

상기 천연 목재판(10)은 원목을 가공하여 형성되는 공지의 것으로, 수분과 햇볕에 의해 강도가 약해지면서 부패되어 쉽게 파손되거나 훼손될 수 있으며 수분과 온도에 따라 상대적으로 쉽게 수축 및 팽창되는 공지의 것이다. 이와 같은 상기 천연 목재판(10)은 원목을 건조시킨 후에 이를 판 형태로 제재하여 제작된다.The natural wood board 10 is a known material formed by processing solid wood, and it may be easily damaged or damaged by decaying as its strength is weakened by moisture and sunlight, and it is a known known that shrinks and expands relatively easily depending on moisture and temperature. will be. The natural wood board 10 is manufactured by drying the solid wood and then cutting it into a plate shape.

상기 베니어합판(20)은 상기 천연 목재판(10)의 상면에 부착되고 나무결이 서로 엇갈리게 다수의 목재박판을 부착하여 형성되는 공지의 것으로, 상기 천연 목재판(10)과 압축 목재판(30)의 사이에 구비되어 상기 천연 목재판(10)과 압축 목재판(30)의 지지하여 그 변형을 극소화시키는 역할을 한다.The veneer plywood 20 is a known one attached to the upper surface of the natural wood board 10 and formed by attaching a plurality of wood thin boards so that the wood grains are crossed with each other, the natural wood board 10 and the compressed wood board 30 It is provided between the natural wood plate 10 and the compressed wood plate 30 to support the role of minimizing its deformation.

상기 압축 목재판(30)은 상기 베니어합판(20)의 상면에 부착되고 천연목재를 상하좌우전후의 모든 방향에서 압축하여 판상으로 형성되는 것으로, 목질 자체가 압축되어 목질 조직의 조밀도 및 치밀도가 높아지면서 내구성과 강도가 현저히 상승되고, 그에 따라 외부 환경에 노출되어도 쉽게 부패되지 않으면서 열이나 수분에 의해 수축 및 팽창이 극소화되어 장수명을 보장하는 역할을 한다. 이와 같은 상기 압축 목재판(30)은 판상의 천연 목재를 가압하여 제작된다.The compressed wood board 30 is attached to the upper surface of the veneer plywood 20 and is formed in a plate shape by compressing natural wood in all directions up, down, left and right, and the wood itself is compressed to achieve the density and density of the woody structure. As is increased, durability and strength are remarkably increased, and accordingly, shrinkage and expansion are minimized by heat or moisture without being easily decayed even when exposed to an external environment, thereby ensuring a long life. The compressed wood board 30 is manufactured by pressing natural wood in the shape of a plate.

도 3은 본 발명의 다른 실시예에 따른 하이브리드 목재판을 보인 개략적인 종단면도이다. 이에 도시된 바와 같이, 본 발명의 다른 실시예에 따른 하이브리드 목재판의 상기 천연 목재판(10)은 방부처리된 방부목, 고열처리된 고열처리목으로 형성되는 것이 바람직한데, 이는 상기 압축 목재판(30)이 외면에 부착되더라도 상기 천연 목재판(10)의 내측이 수분이나 곰팡이에 의해 부패되거나 손상되는 것이 방지되도록 하기 위한 것이다. 아울러, 상기 천연 목재판(10)은 집성되어 형성되는 집성목일 수도 있다.3 is a schematic longitudinal cross-sectional view showing a hybrid wooden board according to another embodiment of the present invention. As shown, the natural wood board 10 of the hybrid wood board according to another embodiment of the present invention is preferably formed of a preservative treated wood, a high heat treated wood, which is the compressed wood board ( Even if 30) is attached to the outer surface, the inside of the natural wood board 10 is to be prevented from being damaged or decayed by moisture or mold. In addition, the natural wood board 10 may be an aggregated wood formed by being aggregated.

본 하이브리드 목재판은 상기 천연 목재판(10)의 상면과 상기 베니어합판(20)의 하면 사이에 부착되고 합성고무 재질로 형성되는 중간흡수판(40)을 더 포함한다. 상기 중간흡수판(40)은 상기 천연 목재판(10)의 열과 수분에 의한 수축과 팽창을 흡수하여 본 하이브리드 목재판이 외부 환경에 노출된 후에 뒤틀려 변형되는 것을 극소화시키는 역할을 한다.The hybrid wood board further includes an intermediate absorption board 40 attached between the upper surface of the natural wood board 10 and the lower surface of the veneer plywood 20 and formed of a synthetic rubber material. The intermediate absorbing plate 40 absorbs contraction and expansion of the natural wood board 10 due to heat and moisture to minimize the distortion and deformation of the hybrid wood board after being exposed to the external environment.

여기서, 상기 압축 목재판(30)은 압축되면서 원래 두께의 20 내지 40%가 감소되어 얇게 형성되는 것이 바람직한데, 이는 20%보다 작게 두께가 감소되면 목질의 조직의 조밀도가 낮아 강도나 내구성이 약해지고 40%보다 높게 두께가 감소되면 과도한 압축으로 압축시 파단되거나 할열되어 불량이 발생할 우려가 있기 때문이다.Here, the compressed wood board 30 is preferably formed to be thinner by reducing 20 to 40% of the original thickness while being compressed. This is because when the thickness is reduced to less than 20%, the density of the woody structure is low, so that strength or durability is reduced. This is because if the thickness is weakened and the thickness is reduced to more than 40%, it may be broken or split during compression due to excessive compression, resulting in defects.

또한, 상기 중간흡수판(40)은 상기 천연 목재판(10) 두께의 1/50 내지 1/30의 두께를 가지는 것이 바람직한데, 이는 상기 천연 목재판(10)의 수축과 팽창에 따른 상기 중간흡수판(40)의 수축과 팽창 정도를 고려한 수치로써, 상기 중간흡수판(40)을 불필요하게 과도한 두께로 개재시키는 것을 최소화하기 위한 것이다.In addition, it is preferable that the intermediate absorbing plate 40 has a thickness of 1/50 to 1/30 of the thickness of the natural wood plate 10, which is the intermediate according to the contraction and expansion of the natural wood plate 10. This is a numerical value in consideration of the degree of contraction and expansion of the absorbent plate 40, and is intended to minimize the interposition of the intermediate absorbent plate 40 with an unnecessarily excessive thickness.
