보강부재가 구비된 합성목재의 가공방법{.}Processing method of synthetic wood with reinforcing member

본 발명은 합성 목재의 가공방법에 관한 것으로, 더욱 상세하게는 구조물의 형상에 맞게 다양한 형상으로 가공이 가능하고, 내구성이 우수한 보강부재가 구비된 합성목재의 가공방법에 관한 것이다.
The present invention relates to a method for processing synthetic wood, and more particularly, to a method for processing a synthetic wood provided with a reinforcing member having excellent durability, which can be processed into various shapes according to the shape of the structure.

일반적으로 목교 내지 목재 데크 등의 목재구조물을 건축시 목재 간의 연결부분은 미관상 좋지 않아 판 형상의 목재를 더 설치하여 목재 간의 연결부분을 가려 마감을 한다.Generally, when constructing wood structures such as wooden bridges or wooden decks, the connections between the timbers are not good in appearance, so that the plate-shaped wood is further installed to cover the connections between the timbers.

일 예로 목재 데크의 경우 데크 상판의 양 측면과 데크의 시작지점과 끝나는 지점에 데크 상판을 지지하는 지지대, 상판 간의 연결부분을 가리도록 데크 상판의 하측 수직방향으로 마감용 목재를 설치하여 마감하였으나, 목재 데크의 양측이 곡선을 이루도록 곡선 길로 설치되었을 경우 마감용 목재를 절단하여 곡선을 따라 여러개의 마감용 목재를 촘촘히 붙여 마감하여야 하는 번거로움이 있었다.For example, in the case of the wooden deck, the finishing timber is installed in the vertical direction of the lower side of the deck top so as to cover the connection between the top plate and the support for supporting the deck top at both sides of the deck top and the starting and ending points of the deck. If both sides of the wood deck were installed in a curved path to form a curve, there was a need to cut the finishing wood and attach several finishing woods closely along the curve to finish.

또한, 목재구조물의 설치 후 시간의 경과에 따라 기후, 온도, 하중, 외부충격 등의 외부요인에 의해 휘거나 뒤틀리는 문제점이 발생하였다.
In addition, there is a problem of bending or twisting due to external factors such as climate, temperature, load, external impact, etc. over time after installation of the wooden structure.
