Description

복합패널 물탱크의 용접방법{WELDING METHOD OF WATER TANK}Welding method of composite panel water tank {WELDING METHOD OF WATER TANK}

본 발명은 복합패널 물탱크의 용접방법에 관한 것으로서, 보다 상세하게는 측면에 결합돌기와 결합홈이 형성된 복합패널을 끼워서 물탱크 형상을 형성하고, 복합패널의 경계선을 폴리에틸렌으로 용접한 후, 그 위에 보강용 부자재를 붙여서 다시 용접하여 물탱크를 완성하는 복합패널 물탱크의 용접방법에 관한 것이다.The present invention relates to a method for welding a composite panel water tank, and more particularly, to form a water tank shape by inserting a composite panel having coupling protrusions and coupling grooves formed on a side surface thereof, and welding the boundary of the composite panel with polyethylene, The present invention relates to a welding method of a composite panel water tank in which a reinforcing auxiliary material is welded again to complete a water tank.

일반적으로 수조(水槽)는 내부에 일정량의 물을 저장하여 주거용 아파트 및 업무용 빌딩 등과 같이 생활용수의 사용이 많은 건축물에 공급하기 위한 것으로서, 재질에 따라 스테인레스패널 수조, 합성수지(SMC)패널 수조, 콘크리트 수조 등으로 분류된다.Generally, a water tank is used to store a certain amount of water inside and supply it to buildings with high use of living water, such as residential apartments and business buildings. Depending on the material, a stainless steel panel tank, a synthetic resin (SMC) panel tank, and concrete It is classified into a tank and the like.

이러한 수조에 있어서 스테인레스패널 수조는 콘크리트 수조의 시공성 문제를 보완한 이점은 있으나, 원자재 가격의 상승으로 비경제적인 문제점이 있고, 합성수지(SMC)패널 수지의 경우는 내구성이 약한 문제점이 있다. 또한, 콘크리트 수조의 경우는, 수압이나 휨하중에 대응하는 구조적강도 및 내구성이 우수한 이점이 있으나, 콘크리트 수조가 형성되도록 결합한 거푸집에 콘크리트를 타설하여 양생시킨 후 거푸집을 철거해야 하는 등 작업공정이 복잡할 뿐만 아니라 공사기간도 많이 소요되는 문제점이 있다.In such a tank, the stainless panel tank has an advantage of complementing the construction problem of the concrete tank, there is an economic problem due to the rise of raw material prices, synthetic resin (SMC) panel resin has a weak durability problem. In addition, in the case of the concrete tank, there is an advantage in that the structural strength and durability corresponding to the hydraulic pressure or bending load is excellent, but the work process is complicated, such as to cast concrete to form the curing to form the concrete tank, and then to remove the formwork. Not only that, there is a problem that requires a lot of construction period.

이 중에서 최근에는 가볍고 값싼 재료인 합성수지로 제작된 단위 패널을 이용하여 수조를 제작하는 경우가 많아지고 있다.Recently, a number of tanks are manufactured using unit panels made of synthetic resin, which is a light and cheap material.

종래기술에 따른 물탱크는 다수개의 단위 패널을 이용하여 저수공간을 형성하고, 외부에는 수압을 지탱할 수 있는 철골프레임을 설치한다.The water tank according to the prior art forms a storage space using a plurality of unit panels, and installs a steel frame frame capable of supporting water pressure outside.

철골프레임과 패널은 볼트나 못 등의 체결수단으로 고정된다.Steel frame and panel is fixed by fastening means such as bolts or nails.

상부면은 뚜껑을 설치하여 외부 이물질이 물에 들어가는 것을 방지하는데, 뚜껑에는 작업자가 청소나 수리를 위해서 물탱크 내부에 들어갈 수 있도록 하는 출입구용 맨홀이 형성될 수 있다. 또한 물탱크의 측면 상부에는 물탱크 내부에 물을 공급하는 인입배관이, 측면 하부에는 물탱크 내부의 물이 배출되는 배출관이 형성된다.The upper surface is provided with a lid to prevent foreign substances from entering the water, the lid may be formed with a manhole for the entrance that allows the operator to enter the water tank for cleaning or repair. In addition, an inlet pipe for supplying water into the water tank is formed at the upper side of the water tank, and a discharge pipe for discharging water in the water tank is formed at the lower side of the water tank.

합성수지로 제작된 패널은 물탱크의 측벽과 바닥면을 형성하면서 물과 직접 접촉하는데, 합성수지에 함유된 원료에 의하여 물이 오염될 염려가 있다.Panels made of synthetic resin form direct side-by-side and bottom surfaces of the water tank, and are in direct contact with water. Water may be contaminated by raw materials contained in the synthetic resin.

이러한 오염을 방지하기 위하여 패널로 형성된 저수공간의 내벽에는 폴리에틸렌(PE) 시트가 융착된다.In order to prevent such contamination, polyethylene (PE) sheet is fused to the inner wall of the storage space formed of the panel.

폴리에틸렌 시트는 물과 접촉하여도 오염을 발생시키지 않으며, 저장된 물이 패널 틈새로 유출되는 것을 막을 수 있기 때문에 대부분의 합성수지패널 물탱크에 널리 사용되고 있다.Polyethylene sheets are widely used in most synthetic resin panel water tanks because they do not cause contamination even when they come into contact with water and can prevent the stored water from leaking into the panel gaps.

그런데 폴리에틸렌 시트를 부착하기 위해서는 두께 약 2~10㎜ 정도의 폴리에틸렌 시트를 제작하고, 물탱크 내부에서 접착제 또는 체결수단을 사용하여 내벽면 에 고정시켜야 한다.However, in order to attach the polyethylene sheet, a polyethylene sheet having a thickness of about 2 to 10 mm should be manufactured and fixed to the inner wall surface by using an adhesive or a fastening means in the water tank.

그리고 폴리에틸렌 시트가 맞닿아 있는 경계부분을 통해 물이 새어나오는 것을 방지하기 위하여 시트의 끝부분을 일정거리만큼 서로 겹쳐서 접착한다.Then, the ends of the sheets are bonded to each other by a predetermined distance in order to prevent the water from leaking through the boundary where the polyethylene sheets are in contact with each other.

이러한 작업을 하는데에는 많은 시간과 노력이 필요하기 때문에 물탱크의 제작기간이 길어지고 제조원가가 상승하는 문제점이 있었다.This work requires a lot of time and effort, so the production period of the water tank is long and there is a problem that the manufacturing cost increases.

또한 각각의 패널을 서로 견고하게 결합하여 물탱크를 제작하는 것이 아니고, 패널을 외부에서 지탱하는 철골프레임을 설치하여 외부에서 수압을 지탱하여야 하므로, 철골프레임의 크기가 커질 수밖에 없었다.In addition, each panel is not firmly combined with each other to produce a water tank, and because the steel frame to support the panel from the outside to support the water pressure from the outside, the size of the steel frame was bound to increase.

즉, 각각의 패널은 외부의 철골프레임에만 고정된 상태에서 힘을 받게 되며, 패널 사이의 틈으로 물이 새는 것은 폴리에틸렌 시트에 의하여 막는다.That is, each panel is subjected to force in a state fixed only to the outer steel frame, and water leaks into the gap between the panels is prevented by the polyethylene sheet.

따라서 철골프레임에 과도한 압력이 부가되어 안전성이 떨어지는 문제점이 있었다.Therefore, the excessive pressure is added to the steel frame had a problem of falling safety.

전술한 문제점을 해결하기 위한 본 발명은 폴리에틸렌 수지로 제작되는 복합패널을 폴리에틸렌 용접봉으로 직접 용접하여 물탱크를 형성함으로써 별도의 쉬트를 물탱크 내부에 설치하는 공정을 없앨 수 있도록 하는 복합패널 물탱크의 용접방법을 제공하는 것을 목적으로 한다.The present invention for solving the above problems is to form a water tank by directly welding a composite panel made of polyethylene resin with a polyethylene welding rod of the composite panel water tank to eliminate the process of installing a separate sheet in the water tank It is an object to provide a welding method.

또한 본 발명은 복합패널의 경계선 위에 보강재를 설치함으로써 수압에 의해 복합패널 사이의 틈이 벌어지는 경우에도 물이 외부로 새어나가지 않도록 하는 복합패널 물탱크의 용접방법을 제공하는 것을 목적으로 한다.In addition, an object of the present invention is to provide a welding method of a composite panel water tank so that water does not leak out even when a gap between the composite panels is opened by hydraulic pressure by installing a reinforcing material on the boundary line of the composite panel.

전술한 문제점을 해결하기 위한 본 발명은 내부에 중공이 길이방향으로 형성되고, 폭방향으로 좌우측에는 고정돌기와 고정홈이 각각 형성되는 복합패널을 접합하여 물탱크를 제작하는 방법으로서, 상기 복합패널의 고정돌기의 일부를 인접한 복합패널의 고정홈에 삽입 고정시켜 물탱크의 바닥면 또는 벽체를 형성하는 제1단계와; 서로 이격된 상태에서 결합된 두 개의 복합패널의 경계선을 따라 폴리에틸렌 용접봉으로 용접하는 제2단계와; 상기 복합패널의 경계선을 덮는 용접용 부자재를 설치하는 제3단계와; 상기 용접용 부자재와 상기 복합패널이 접촉하는 경계선을 따라 폴리에틸렌 용접봉으로 용접하는 제4단계와; 용접된 부위를 냉각시키는 제5단계;를 포함한다.The present invention for solving the above problems is a method of manufacturing a water tank by joining a composite panel in which the hollow is formed in the longitudinal direction inside, the left and right sides in the width direction, respectively, the fixing projection and the fixing groove, Inserting and fixing a portion of the fixing protrusion into the fixing groove of the adjacent composite panel to form a bottom surface or a wall of the water tank; A second step of welding with a polyethylene welding rod along a boundary line of two composite panels joined in a spaced apart state; A third step of installing a welding subsidiary material covering a boundary line of the composite panel; A fourth step of welding with a polyethylene welding rod along a boundary line between the welding subsidiary material and the composite panel; And a fifth step of cooling the welded portion.

상기 제2단계는 상기 복합패널과 인접한 복합패널 사이에 형성된 이격홈 내 부에 상기 폴리에틸렌 용접봉을 용융 삽입시켜 접합하는 것을 특징으로 한다.In the second step, the polyethylene welding rod is melt-bonded into the spaced groove formed between the composite panel and the adjacent composite panel.

상기 제2단계와 제4단계는 170℃ 내지 180℃의 열풍으로 용접할 부위를 1차로 예열하는 단계와; 220℃ 내지 230℃의 열풍으로 용접할 부위를 2차로 예열하는 단계와; 상기 예열된 부위에 용융된 폴리에틸렌을 주입하여 접합하는 단계;를 포함한다.The second step and the fourth step is the step of preheating the first portion to be welded by hot air of 170 ℃ to 180 ℃; Preheating a second portion to be welded with hot air at 220 ° C. to 230 ° C .; And injecting molten polyethylene into the preheated portion to bond.

본 발명에 따르면 복합패널을 직접 용접에 의해 물탱크를 제작함으로써 제작 기간을 단축하고 원가를 절감할 수 있으며, 수압의 작용에 의해 물탱크가 갈라져서 물이 새어나오는 것을 방지할 수 있는 효과가 있다.According to the present invention, by manufacturing the water tank by direct welding the composite panel can shorten the production period and reduce the cost, there is an effect that can prevent the water tank from leaking by splitting the water tank by the action of hydraulic pressure.

이하에서 도면을 참조하여 본 발명의 실시예에 따른 복합패널 물탱크의 용접방법(이하, '용접방법'이라 함)을 설명한다.Hereinafter, a welding method (hereinafter, referred to as a 'welding method') of a composite panel water tank according to an exemplary embodiment of the present invention will be described with reference to the drawings.

도 1은 물탱크의 외벽을 구성하는 복합패널의 구조를 나타낸 사시도이며, 도 2는 두 장의 복합패널을 결합한 상태를 나타낸 사시도이다.1 is a perspective view showing the structure of the composite panel constituting the outer wall of the water tank, Figure 2 is a perspective view showing a state in which the two composite panels combined.

물탱크를 형성하는 복합패널(100)은 평판형의 합성수지 패널로서 폴리에틸렌(PE) 수지로 제작된다. 폴리에틸렌 수지는 인체에 무해한 수지로서 물탱크 내부의 물과 접촉해도 괜찮은 재질이어서 물탱크의 제작에 많이 사용된다.The composite panel 100 forming the water tank is made of polyethylene (PE) resin as a flat synthetic resin panel. Polyethylene resin is a resin that is harmless to the human body and is a material that may be in contact with water in the water tank, and thus is widely used in the manufacture of the water tank.

여기서 복합패널(100)이란 내부와 외표면의 재질이 다른 상태인 패널을 말한다. 즉, 내부는 재생상태의 폴리에틸렌 원료를 사용하여 제작되며, 외표면에는 순원료 상태의 폴리에틸렌 원료가 사용된다. 재생원료는 순원료에 비하여 경도가 높고 가격이 저렴하므로, 복합패널(100)의 내부에 투입된 재생원료에 의해 복합패널(100)의 가격은 낮아지면서 강도는 더 세지는 효과가 있다.Here, the composite panel 100 refers to a panel in which the materials of the inner and outer surfaces are different. That is, the inside is produced using a polyethylene raw material in a regenerated state, and the polyethylene raw material in a pure raw state is used for the outer surface. Since the recycled raw material has a higher hardness and lower price than the net raw material, the recycled raw material injected into the composite panel 100 lowers the price of the composite panel 100 while increasing the strength.

순원료와 재생원료를 압출 금형에 함께 투입하면서 압출 방식으로 성형하면 내부와 외부가 일체로 형성된 복합패널(100)을 제작할 수 있다.When the raw material and the regenerated raw material are put together in an extrusion mold and molded in an extrusion method, the composite panel 100 may be manufactured in which the inside and the outside are integrally formed.

그리고 복합패널(100)의 폭방향으로 좌우측에는 고정돌기(102)와 고정홈(104)이 각각 형성된다. 고정돌기(102)의 외측 넓이와 고정홈(104)의 내측 넓이는 동일하므로 고정돌기(102)가 고정홈(104) 내부에 억지끼움식으로 끼워지면서 두 개의 복합패널(100)이 서로 연결된다.In addition, fixing protrusions 102 and fixing grooves 104 are formed at left and right sides in the width direction of the composite panel 100, respectively. Since the outer width of the fixing protrusion 102 and the inner width of the fixing groove 104 are the same, the two complex panels 100 are connected to each other while the fixing protrusion 102 is inserted into the fixing groove 104 by interference fit. .

또한 복합패널(100)의 내부에는 길이방향으로 다수 개의 중공(106)이 형성된다. 중공(106)은 복합패널(100)의 중량을 감소시키며 원료의 감소를 통한 제작비용 절감효과를 내기 위한 구성이다. 또한 복합패널(100) 내부에 공기층을 형성함으로써 단열효과를 향상시킨다.In addition, a plurality of hollows 106 are formed in the longitudinal direction of the composite panel 100. The hollow 106 is configured to reduce the weight of the composite panel 100 and to reduce the manufacturing cost by reducing the raw material. In addition, by forming an air layer inside the composite panel 100 to improve the heat insulating effect.

이러한 복합패널(100)을 다수 개 연결하여 물탱크의 바닥면이나 벽체를 형성한다.A plurality of such composite panels 100 are connected to form a bottom surface or a wall of the water tank.

도 2에서와 같이 두 개의 복합패널(100)을 연결할 때에는 결합돌기(102)가 결합홈(104) 내부에 완전히 들어가지 않도록 함으로서 복합패널(100) 사이에 약간의 이격된 틈이 생기도록 한다.When connecting the two composite panels 100 as shown in Figure 2 so that the coupling projection 102 is not completely entered into the coupling groove 104 so that a slight spaced gap between the composite panel 100 occurs.

도 3은 복합패널 사이를 용접한 상태를 나타낸 사시도로서, 복합패널(100) 사이에 형성된 이격된 틈새에 용접봉을 녹여넣어서 접합부(112)를 형성한 상태를 나타내고 있다.3 is a perspective view showing a state in which the composite panels are welded, and shows a state in which a joint 112 is formed by melting a welding rod in spaced gaps formed between the composite panels 100.

만약 복합패널(100) 사이에 틈이 생기지 않은 경우에는 폴리에틸렌 용접봉이 용융된 상태에서 복합패널(100)의 표면에만 존재하기 때문에 접합력이 떨어져서 수압에 의해 복합패널(100) 사이가 벌어지게 된다. 이를 방지하기 위해서 이격된 틈새에 용접봉을 삽입한다.If there is no gap between the composite panel 100, since the polyethylene welding rod is present only on the surface of the composite panel 100 in a molten state, the bonding force is dropped, so that the composite panel 100 is opened by hydraulic pressure. To prevent this, insert the electrode in the spaced gap.

다음으로 도 4는 복합패널의 경계선 위에 부자재를 설치한 상태를 나타낸 사시도로서, 복합패널(100) 사이의 접합부(112) 위에 용접용 부자재(200)가 부착된 상태를 나타내고 있다. 용접용 부자재(200)는 물탱크에 가해지는 수압을 지탱하기 위한 보강재로서, 폴리에틸렌 수지재로 제작되어 약간의 탄성을 가진다.Next, FIG. 4 is a perspective view showing a state in which a subsidiary material is installed on a boundary line of the composite panel, and shows a state in which a welding subsidiary material 200 is attached to a joint 112 between the composite panel 100. The welding subsidiary material 200 is a reinforcing material for supporting the hydraulic pressure applied to the water tank, and is made of polyethylene resin to have some elasticity.

용접용 부자재(200)는 단면이 I자 또는 L자 형로서, 두 개의 복합패널(100)이 하나의 평면상에서 만나서 평면을 구성하는 경우에는 I자형을 사용하며, 수직인 평면상에서 만나서 ㄱ자 또는 꼭지점을 구성하는 경우에는 L자형을 사용한다.The welding subsidiary material 200 has an I-shaped or L-shaped cross section, and when the two composite panels 100 meet on one plane to form a plane, an I-shape is used. L-shape is used when constructing.

그리고 부자재(200)는 길이방향으로 비교적 긴 띠 형태로 제작되는데, 복합패널(100)의 경계선과 맞닿는 면에는 길이방향으로 다수의 홈(202)이 형성된다. 부자재(200)에 형성된 홈(202)은 복합패널(100) 사이에 형성된 접합부(112)를 수용하게 되며, 수압에 의해 복합패널(100) 사이가 벌어졌을 때, 탄성이 있는 부자재(200)가 상하 또는 좌우로 벌어지게 된다. 따라서 복합패널(100)과의 접촉이 그대로 유지되면서 물탱크에 저장된 물이 외부로 새어나가지 않도록 해준다.The subsidiary material 200 is formed in a relatively long strip shape in the longitudinal direction, and a plurality of grooves 202 are formed in the longitudinal direction on a surface contacting the boundary line of the composite panel 100. The groove 202 formed in the subsidiary material 200 accommodates the joint portion 112 formed between the composite panel 100, and when the gap between the composite panel 100 is opened by hydraulic pressure, the subsidiary material 200 having elasticity is vertically up and down. Or left and right. Therefore, the contact with the composite panel 100 is maintained as it is so that the water stored in the water tank does not leak to the outside.

다음으로 도 5는 부자재의 측면을 용접한 상태를 나타낸 사시도로서, 부자재(200)와 복합패널(100)이 만나고 있는 경계선을 따라 폴리에틸렌 용접봉을 녹여 용접한다. 부자재(200)와 복합패널(100) 사이의 접합부(114)가 형성됨으로써 부자재(200)가 방수기능을 할 수 있게 된다.Next, FIG. 5 is a perspective view showing a state in which the side surfaces of the subsidiary materials are welded, and the polyethylene welding rods are melted and welded along a boundary line where the subsidiary materials 200 and the composite panel 100 meet. Since the junction part 114 between the subsidiary material 200 and the composite panel 100 is formed, the subsidiary material 200 may perform a waterproof function.

한편, 도 6은 용접장치의 사용상태를 나타낸 사시도이며, 도 7은 용접장치의 구조를 나타낸 측면도이다.On the other hand, Figure 6 is a perspective view showing a state of use of the welding device, Figure 7 is a side view showing the structure of the welding device.

도 6과 7에 도시된 용접장치(300)는 본 발명의 용접방법을 적용하기 위해서 사용되는 장치로서, 폴리에틸렌 원료를 용융하여 공급하는 장치(도면 미도시)의 말단에 구비된다.6 and 7 is a device used to apply the welding method of the present invention, it is provided at the end of the device (not shown) for melting and supplying polyethylene raw material.

용접장치(300)의 상단에는 용융상태의 폴리에틸렌 원료를 공급하는 공급관(302)이 구비된다. 공급관(302)의 말단에는 접촉플레이트(304)가 구비되는데, 접촉플레이트(304)는 복합패널(100)의 측면과 접촉하면서 용접 부위를 정해주는 역할을 한다.The upper end of the welding device 300 is provided with a supply pipe 302 for supplying the polyethylene raw material in the molten state. The end of the supply pipe 302 is provided with a contact plate 304, the contact plate 304 serves to determine the welding site while in contact with the side of the composite panel (100).

접촉플레이트(304)의 가운데에는 용융된 폴리에틸렌이 배출되는 토출관(306)이 형성된다. A discharge tube 306 through which molten polyethylene is discharged is formed in the center of the contact plate 304.

접촉플레이트(304)의 옆에는 1차예열관(308)이 돌출 형성된다. 1차예열관(308)은 토출관(306)으로부터 용접장치(300)의 진행방향에 위치한다. 1차예열관(308)을 통해 고온의 열풍이 배출되면서 용접될 복합패널(100)을 가열하여 폴리에틸렌 용접이 원활하게 이루어지도록 한다.Next to the contact plate 304, a primary preheating tube 308 is formed to protrude. The primary preheating tube 308 is located in the advancing direction of the welding apparatus 300 from the discharge tube 306.
