Description

폴리에틸렌패널이 부착된 복합거푸집패널Composite formwork panel with polyethylene panel

본발명은 표면에 폴리에틸렌패널을 목재패널에 접착제로서 간편하게 접착하여 제작되는 폴리에틸렌패널이 부착된 복합거푸집패널에 관한 것이다.The present invention relates to a composite formwork panel with a polyethylene panel produced by simply adhering the polyethylene panel to the wood panel as an adhesive.

보통 합판으로 제작되는 목재거푸집패널은 절단이 용이하고, 중량에 비하여 콘크리트의 측압에 대한 감당능력이 우수하여 건설현장에서 가장 보편적인 거푸집패널로서 널리 사용되어 오고 있다.Wood formwork panel, which is usually made of plywood, is easy to cut and has excellent ability to cope with the side pressure of concrete compared to its weight, and has been widely used as the most common formwork panel in construction sites.

그러나, 이러한 목재거푸집패널은 내수성이 없으며, 표면에 콘크리트가 잘 달라붙는 특성을 가진다. 따라서 목재거푸집패널은 사용할 때마다 그 표면에 박리제를 도포해야 하는 결함을 가진다. 또, 이와같이 표면에 박리제를 도포하여 사용한다고 하여도, 몇회이상 반복사용되면 콘크리트로 인하여 표면이 손상되어서 더 이상 사용이 불가능한 상태가 된다.However, such wood formwork panels are not water resistant and have a property that concrete adheres well to the surface. Therefore, the wooden formwork panel has a defect that a release agent must be applied to the surface of the wood formwork panel every time it is used. In addition, even when the release agent is applied to the surface in this way, if used repeatedly several times or more, the surface is damaged due to concrete, which is no longer usable.

이에 반하여 폴리에틸렌패널은 내수성, 표면박리성 및 내구성이 매우 탁월하므로, 우수한 거푸집패널로서 사용될수 있다. 그러나, 이러한 폴리에틸렌 패널은 합판에 비하여 매우 비싸며, 하중에 대한 감당능력이 크게 떨어져서, 독자적인 거푸집패널로서 사용되기 곤란한 문제점이 있었다. 따라서, 폴리에틸렌패널은 독자적인 거푸집패널로 사용되기 보다는 목재패널 또는 금속재패널와 결합되는 복합거푸집패널로서 제작되어서 사용되어 왔다.On the contrary, the polyethylene panel is very excellent in water resistance, surface peeling and durability, and thus can be used as an excellent formwork panel. However, these polyethylene panels are very expensive compared to plywood, and the ability to withstand loads is greatly degraded, which makes it difficult to use them as independent form panels. Therefore, polyethylene panels have been manufactured and used as composite form panels combined with wood panels or metal panels, rather than as individual form panels.

그런데, 합성수지재중에서 폴리에틸렌은 화학적인 안정성이 탁월하여서 동일한 재질사이의 용융접합외에는 별도의 접착제가 없는 것으로 알려져 있다. 이러한 특성을 가지는 폴리에틸렌패널과 목재패널을 상호간에 접착제로서 잡착하여 결합시키는 것은 불가능하다고 여겨진다.However, polyethylene is known to have excellent chemical stability in synthetic resin materials, so that there is no separate adhesive except for melt bonding between the same materials. It is considered impossible to bond the polyethylene panel and the wooden panel having such characteristics to each other as adhesives.

따라서, 폴리에틸렌패널과 목재패널로서 이루어지는 종래의 복합거푸집패널(100)은 도1에 도시와 같이 폴리에틸렌패널(110)과 목재패널(120) 또는 금속재패널이 나사못이나 볼트 또는 리벳등의 고정수단(130)으로 적절한 위치마다 고정되어서 제작되어 왔다.Therefore, the conventional composite formwork panel 100 made of a polyethylene panel and a wood panel, as shown in Figure 1, the polyethylene panel 110 and the wood panel 120 or a metal panel fixing means such as screws, bolts or rivets 130 Has been fixed at every appropriate position.

이러한 형태의 복합거푸집패널은 세가지 방면의 문제점들이 있었다.This formwork composite panel had three problems.

첫째는 고정수단으로 소정의 위치마다 두가지의 이질재료의 패널들을 상호 고정하는 번거로운 작업을 통하여 제작되어야 하는 제작상의 문제이며, 둘째는 제작된 복합거푸집패널에는 도2에서와 같이 폴리에틸렌패널의 표면에 고정수단이 노출되어서 반복사용시 고정수단이 마모되거나 손상되는 고정수단의 손상문제이며, 셋째는 계절의 변화에 따라 온도신축현상이 발생될 때에 이질재료들끼리의 열팽창계수가 크게 다름으로 인하여 고정수단들의 주변에서 발생되는 폴리에틸렌패널의 손상문제이다.The first is a manufacturing problem that has to be produced through the cumbersome work of fixing two panels of heterogeneous materials to each predetermined position as a fixing means, and the second is fixed to the surface of the polyethylene panel as shown in FIG. The problem is the damage of the fixing means that the fixing means is worn or damaged when repeated use of the means is exposed. Third, the thermal expansion coefficient of the heterogeneous materials is different when the temperature expansion phenomenon occurs due to the change of season. This is a problem of polyethylene panel damage occurring in

본 발명의 목적은 첫째 제작이 간편하면서도 고정수단이 표면에 노출되지 않고 온도신축에 따른 국부적인 파손이 근원적으로 방지되는 폴리에틸렌패널이 부착된 복합거푸집패널을 제공하는 데 있으며, 둘째 하중에 대한 감당능력과 절단가공성이 우수하면서도 내수성, 표면박리성 및 내구성이 동시에 구비되는 폴리에틸렌패널이 부착된복합거푸집패널을 제공하는 데 있다.It is an object of the present invention to provide a composite formwork panel with a polyethylene panel, which is firstly fabricated and yet prevents the fixing means from being exposed to the surface and prevents local damage due to temperature stretching. The present invention provides a composite formwork panel with a polyethylene panel having excellent cutting processability and water resistance, surface peelability and durability at the same time.

이하, 본 발명의 기술적구성을 상세히 살펴보면 다음과 같다.Hereinafter, the technical configuration of the present invention in detail.

본 발명의 복합거푸집패널(100)은 도3 내지 도5에 도시되는 바와 같이, 섬유사(11a)로 직조한 섬유직포(11)가 폴리에틸렌패널의 용융성형중에 표면에 매립되어서 성형제작되는 섬유직포가 부착된 폴리에틸렌패널(10)과, 상기 폴리에틸렌패널(10)의 섬유직포면(A)에 접착제를 도포하여 형성되는 접착층(20)과, 상기 접착층(20)에 접착되는 목재패널(30)로 구성된다.In the composite formwork panel 100 of the present invention, as shown in Figures 3 to 5, the fiber woven fabric 11 woven from the fiber yarn (11a) is embedded in the surface during the melt molding of the polyethylene panel, the fabric woven fabric Is attached to the polyethylene panel 10, the adhesive layer 20 formed by applying an adhesive to the fiber fabric surface (A) of the polyethylene panel 10, and the wooden panel 30 adhered to the adhesive layer 20 It is composed.

여기에서, 목재패널(30)은 합판을 지칭하는 것이 보통이며, 폴리에틸렌패널(10)은 두께가 비교적 얇은 폴리에틸렌 시이트와 두께가 비교적 두꺼운 폴리에틸렌판재를 총칭하는 용어로서 사용된다. 상기 접착제는 목재용 접착제나 보편적으로 접착력이 우수한 것으로 알려진 폴리우레탄, 에폭시 또는 폴리에스테르계통의 접착제가 사용될 수도 있다.Here, the wood panel 30 generally refers to plywood, and the polyethylene panel 10 is used as a generic term for a polyethylene sheet having a relatively thin thickness and a polyethylene sheet having a relatively thick thickness. The adhesive may be a wooden adhesive or a polyurethane, epoxy or polyester-based adhesive commonly known as excellent adhesive strength.

이와 같이 접착이 불가능한 것으로 여겨졌던 폴리에틸렌패널(10)을 목재패널(30)과 접착제로서 간편하게 접착하는 것이 가능하도록 하는 구체적인 이유는 다음과 같다. 즉, 폴리에틸렌은 화학적으로 매우 안정되므로 용융접합이외에는 접착방법이 없는 소재이다. 이러한 특성을 가지는 폴리에틸렌패널(10)은 용융성형중에 그 표면부에 섬유직포(11)를 프레싱하면, 섬유직포(11)가 그 표면부에 매립되어 성형된다. 이때, 섬유직포(11)의 미세한 섬유사(11a)들은 폴레에틸렌패널(10)의 표면내부에 마치 식물의 뿌리털과 같이 깊이있게 박혀져서, 섬유직포(11)가 폴리에틸렌패널(10)에 견고하게 결합되도록 한다.Thus, the specific reason for making it possible to easily bond the polyethylene panel 10, which was considered to be non-adhesive, with the wood panel 30 as an adhesive is as follows. In other words, polyethylene is chemically very stable, and thus it is a material having no bonding method other than melt bonding. In the polyethylene panel 10 having such characteristics, when the fiber woven fabric 11 is pressed to the surface portion during melt molding, the fiber woven fabric 11 is embedded in the surface portion and molded. At this time, the fine fiber yarns (11a) of the fiber woven fabric 11 is embedded in the surface of the polyethylene panel 10 as deeply as the root hairs of plants, so that the fiber woven fabric 11 is firmly attached to the polyethylene panel (10) To be combined.

이와같이 제작된 섬유직포(11)가 부착된 폴리에틸렌패널(10)의 섬유직포면(A)에 접착제를 도포하면, 도포된 접착제는 섬유직포(11)를 구성하는 직조된 섬유사(11a)들의 틈새를 통한 모세관 현상으로 폴리에틸렌패널(10)의 표면내부에 박혀진 미세한 섬유사(11a)들의 말단부까지 침투되어서 견고하고도 치밀한 접착층(20)을 형성한다.When the adhesive is applied to the fiber woven surface A of the polyethylene panel 10 to which the fabric woven fabric 11 is attached as described above, the applied adhesive is a gap between the woven fiber yarns 11a constituting the fiber woven fabric 11. The capillary phenomenon penetrates into the distal ends of the fine fiber yarns 11a embedded in the surface of the polyethylene panel 10 to form a strong and dense adhesive layer 20.

따라서, 본발명의 복합거푸집패널(100)은 위에서 살펴본 바와 같이 견고하고도 치밀한 접착층(20)을 통하여 목재패널(30)과 폴리에틸렌패널(10)을 접착하여 제작되므로 제작이 간편한 효과를 가지며, 별도의 고정수단이 사용되지 아니하므로, 고정수단이 표면에 노출되지 않고 온도신축에 따른 고정수단의 주변의 국부적인 파손이 근원적으로 방지되는 효과를 가지며, 하중에 대한 감당능력과 절단가공성이 우수하면서도 내수성, 표면박리성 및 내구성이 동시에 구비되는 효과를 가지게 된다.Therefore, the composite formwork panel 100 of the present invention is produced by adhering the wood panel 30 and the polyethylene panel 10 through the solid and dense adhesive layer 20 as described above, so that the production has a simple effect, and separate Since the fixing means of is not used, the fixing means is not exposed to the surface, and the local damage around the fixing means due to the temperature expansion and contraction is fundamentally prevented. , Surface peeling and durability will be provided at the same time.
