Description

목제 합판{The wooden sheet of plywood}Wood plywood {The wooden sheet of plywood}

본 고안은 원목상태에서 소정두께로 제재된 합판부재들을 목재의 결방향을 달리하여 적층접합된 상태로 구성되는 합판에 관한 고안이다.The present invention is a design for a plywood consisting of a laminate bonded state by varying the direction of the wood plywood members made of a predetermined thickness in the wood state.

합판은 건축물의 내외장부재는 물론 콘크리트 거푸집 등으로 이용되고 있으며 목재가 갖는 특성때문에 온도변화 등에 의한 변형을 최소화하기 위하여 여러장의 합판부재를 적층접합하고 있으며 강력한 접착력과 내수성, 내마모성을 고려하여 여러가지 수지계통의 접착응고제를 사용하고 있다.Plywood is used not only for interior and exterior members of buildings, but also for concrete formwork. Due to the characteristics of wood, several plywood members are laminated and bonded together to minimize deformation due to temperature changes, and various resins are considered in consideration of strong adhesiveness, water resistance, and abrasion resistance. A system of adhesive coagulant is used.

합판에 이용되는 접착수지는 페놀수지(Phenol Resin)가 많이 이용되고 있으며 페놀수지는 강한 접착과 응고력 및 내수성, 내마모성, 내알칼리성을 갖는 것으로 특히 합판의 접착용도로는 이상적이다.Phenol resin is widely used as the adhesive resin used for plywood, and phenol resin has strong adhesion, coagulation force, water resistance, abrasion resistance, and alkali resistance, and is particularly ideal for bonding of plywood.

종래 합판의 구성을 보면,Looking at the configuration of conventional plywood,

원목상태에서 소정두께로 제재한 시트상태의 기판부재를 여러장 적층하되 각 기판부재의 목재결이 서로 상반되도록 적층하는 것으로 페놀수지를 스프레이하여 프레스가압하거나 페놀수지에 침지시킨후 프레스가압 또는 증기가압 방법으로 합판을 제조하였던 것이다.Lay several sheets of board member in a wooden state with a predetermined thickness. Laminate the wood grains of each board member to be opposite to each other. Spray the phenol resin by pressing or immersing it in the phenol resin, and then press or steam The plywood was produced by the method.

물론 합판의 이용용도에 따라서 합판의 강도를 조절하는 방법이 알려지고 있으며 동일한 원자재와 동일한 규격의 합판일 경우 접착제의 종류나 침지시간 또는 스프레이양에 따라서 합판의 강도가 조절될 수 있고 목재의 특성에 따라 합판의 강도가 조절될 수 있는 것이다.Of course, it is known how to control the strength of plywood according to the use of plywood.In the case of plywood with the same raw materials and the same specifications, the strength of plywood can be adjusted according to the type of adhesive, immersion time or spray amount. Therefore, the strength of the plywood can be adjusted.

그러나 종래 합판의 경우 원목을 가로결 방향으로 제재한 여러장의 시트상태기판부재를 가로결이 서로 다른 방향이 되도록 적층하여 접합한 집성판을 제조하고 집성판 표면에 소정 두께의 마감부재를 접착시킨 것으로 단순히 기판의 목재결 방향만 달리하여 접합시킴으로써 변형 방지의 목적 달성은 가능하나 강도가 크게 떨어지는 문제점이 있게 되는 것이다.However, in the case of conventional plywood, the laminated sheet laminated with a plurality of sheet state substrate members in which the solid wood is intersected in a direction different from each other to produce a laminated sheet bonded to each other, and simply bonded the finishing member of a predetermined thickness on the surface of the laminated sheet It is possible to achieve the purpose of preventing deformation by joining only by different direction of the wood grain, but the strength is greatly reduced.

본 고안은 상기 종래 합판의 문제점을 개선하기 위한 합판을 제시한다.The present invention proposes a plywood for improving the problems of the conventional plywood.

본 고안 합판은 목재결이 각각 다른 방향이 되도록 다수의 시트상태의 기판부재를 접합한 기판을 적당한 폭이되도록 종방향으로 절단하여 낱개 단위의 집성판부재로 구성하고 낱개 단위의 집성판부재를 횡방향으로 다수 접합하여 집성판을 구성한다.The plywood of the present invention is composed of individual unit board members by cutting the boards in which the boards are joined to a plurality of sheet members in a different direction so that the wood grains are in different directions in the longitudinal direction so as to have a suitable width. It joins many in a direction and comprises an aggregation plate.

이렇게 구성된 2장의 집성판을 상하 적층접합하되 집성판부재의 배열상태가 서로 상반되게 접합한 상하 집성판의 표면에 소정두께의 마감부재를 접합시켜 변형이 없고 내구성 및 절곡강도가 매우 높은 합판을 구성하는 것이 본 고안의 기술적 과제이다.The laminated sheets of two sheets are thus vertically laminated and bonded together with the finishing member of a predetermined thickness on the surface of the upper and lower laminated sheets, in which the arrangement state of the laminated sheet members is opposite to each other, thereby forming a plywood having high durability and bending strength. It is a technical problem of the present invention.

소정두께로 제재된 다수의 기판부재(10)에 페놀수지를 스프레이하여 가로목재결(10')이 서로 상반되게 적층한 다음 소정압력으로 프레스하여 구성되는 기판(100)과 기판(100)을 소정폭이 되게 종방향으로 절단한 다수의 집성판부재(20)와 상기 다수의 집성판부재(20)에 페놀수지를 스프레이하여 횡방향으로 프레스 접합시켜 구성되는 집성판(200)과 상기 2장의 집성판(200)에 페놀수지를 스프레이하여 하부 집성판(200)은 접합선(200')이 종방향이 되도록 하고 상부 집성판(200)은 접합선(200')이 횡방향이 되도록 프레스 접합하여 구성되는 집성판본체(400)와 상기 집성판본체(400)의 표면에 부착되는 마감부재(300)로 이루워진다.The substrate 100 and the substrate 100, which are formed by spraying phenolic resins on a plurality of substrate members 10 made of a predetermined thickness and stacking the horizontal wood grains 10 'in opposition to each other, and then pressing them at a predetermined pressure, are selected. Aggregate plate 200 and the two aggregates, which are formed by spraying phenolic resin onto the plurality of aggregate plate members 20 and the plurality of aggregate plate members 20 which are cut in the longitudinal direction to have a width, and press bonding in the transverse direction. The phenol resin is sprayed onto the plate 200 so that the lower aggregation plate 200 is connected to the bonding line 200 'in the longitudinal direction, and the upper aggregation plate 200 is press-bonded so that the bonding line 200' is in the transverse direction. It is made of an aggregate plate body 400 and a finishing member 300 attached to the surface of the aggregate plate body 400.

본 고안에서 상기 집성판(200)은 이용 용도에 따라서 2장, 3장 또는 4장 까지 접합선(200')이 각각 교호로 상반되게 적층하여 합판의 강도와 두께를 조절할 수가 있다.In the present invention, the aggregate plate 200 may be laminated with two, three or four bond lines 200 'alternately opposite to each other depending on the intended use, thereby controlling the strength and thickness of the plywood.

또한 상기 기판부재(10)의 두께는 0.5 ~ 5m/m 가 적합하며, 상기 기판(10)을 종방향으로 절단하여 구성된 집성판(200)의 두께는 1 ~ 10m/m 가 바람직하다.In addition, the thickness of the substrate member 10 is suitable for 0.5 ~ 5m / m, the thickness of the aggregate plate 200 formed by cutting the substrate 10 in the longitudinal direction is preferably 1 ~ 10m / m.

상기한 구성을 갖는 본 고안 합판의 작용 효과를 설명한다.Effects of the present invention plywood having the above configuration will be described.

본 고안 합판은 기판(100)을 소정 폭으로 절단하여 집성판부재(20)로 구성하고 상기 집성판부재(20)를 종방향으로 세워서 가로방향으로 접합시킴으로써 종방향으로 세워진 집성판부재(20)는 세로 목재결이 서 있는 상태가 됨으로 일반 합판과 같이 가로 목재결이 누워있는 것에 비하여 강도가 크게 높아지는 것이다.The plywood according to the present invention is composed of an aggregate plate member 20 by cutting the substrate 100 to a predetermined width, and the aggregate plate member 20 erected in the longitudinal direction by joining the aggregate plate member 20 in the longitudinal direction in the horizontal direction. As the vertical wood grain is standing, the strength is greatly increased compared to the horizontal wood grain laying like a general plywood.

본 고안 합판과 일반 합판의 강도 실험은 하기와 같다.The strength test of the inventive plywood and the general plywood is as follows.

[실험예]Experimental Example

동일한 두께(2cm) 동일한 넓이(100㎤)의 본 고안 합판과 기존 합판 위에 무게 300kg의 중량체를 20시간 동안 올려놓았더니 본 고안 합판은 아무런 변형이 없이 수평상태를 유지하였으나 일반 합판은 합판의 중심부를 향해 만곡상태로 굴절되어 있었다.After placing the 300kg weight on the plywood and the existing plywood of the same thickness (2cm) and the same width (100cm3) for 20 hours, the plywood of the present invention remained horizontal without any deformation, but the general plywood is the center of the plywood. It was bent in a curved state toward.

본 고안 합판은 제조방법이 일반 합판의 제조방법에 비하여 그 공정이 간단하여 다량생산이 가능하며 강도가 높고 내구성이 우수하며 거의 변형되지 않는 원상태를 유지할 수가 있어서 다양한 용도로 널리 이용될 수 있는 효과를 얻을 수 있다.The plywood of the present invention has the effect that can be widely used for various purposes because the manufacturing method is simpler than the manufacturing method of general plywood, so the mass production is possible, the strength is high, the durability is excellent, and it can be maintained almost without deformation. You can get it.
