Description
본 발명은 전주 금형의 말구판 구조에 관한 것으로서, 보다 상세하게는 송전을 위한 전선을 지지하는 전주의 제조현장에서 원심 주조에 이용되는 금형장치의 말구판을 개선하여 공정을 단순화하면서도 고품질을 유지하는 전주 금형의 말구판 구조에 관한 것이다.The present invention relates to a structure of a horse plate of an electric pole, and more particularly, to improve the horse plate of a mold apparatus used for centrifugal casting at a manufacturing site supporting electric wire for power transmission, thereby simplifying a process and maintaining high quality. It relates to the structure of the horse plate of the electroforming die.
일반적으로 전주는 완만한 구배를 지니는 원기둥 형태로서 7 ∼17m까지 다양한 길이로 제작되는데 지면에 매설되는 단부를 원구라 하고 그 반대측 단부를 말구라 한다. 이러한 전주는 콘크리트를 기본 소재로 하지만 복수의 철재 와이어로 형성한 프레임을 몰딩하여 강도를 증가시킨다.Generally, a pole is a cylindrical shape with a gentle gradient and is manufactured in various lengths from 7 to 17m. The end buried in the ground is called a circle and the opposite end is called. This pole is made of concrete as a base material, but increases the strength by molding a frame formed of a plurality of steel wire.
도 1은 종래의 전주 금형장치를 부분 절개하여 나타내는 구성도가 도시된다.1 is a block diagram showing a partial cutaway of a conventional electroforming mold apparatus.
전주를 제작하기 위한 금형장치는 상형(11)과 하형(12)으로 구분되고 양단에 원구 및 말구를 형성하기 위해 각각 원구판(19) 및 말구판(13)이 장착되는 구성을 지닌다. 상형(11)과 하형(12)의 외주면에는 복수의 림(18)이 형성되어 회전롤러(도시 생략)에 접촉된 상태로 회전력을 전달받을 수 있다. 와이어(10)의 일단을 지지하는 인장판(14)은 스크류(15)를 개재하여 외부의 인장기(17)에 연결된다.The mold apparatus for manufacturing a pole is divided into an upper mold 11 and a lower mold 12 and has a configuration in which a sphere plate 19 and a horse plate 13 are mounted to form a sphere and a horse sphere at both ends, respectively. A plurality of rims 18 are formed on the outer circumferential surfaces of the upper mold 11 and the lower mold 12 to receive the rotational force in contact with a rotating roller (not shown). The tension plate 14 supporting one end of the wire 10 is connected to an external tensioner 17 via a screw 15.
작업공정을 살펴보면, 복수의 와이어(10)를 길이 방향으로 배치한 후 그 둘레에 가는 와이어를 나선형으로 감아 용접하여 프레임을 형성하고, 형성된 프레임에서 길이 방향으로 배치되는 와이어의 단부를 가열 가압하여 헤드(10a)를 형성하고, 상형(11)과 하형(12)에 이형제를 도포하고, 와이어(10)의 양단에 말구판(13)과 원구판(19)을 장착한 상태로 하형(12)에 안착하고, 와이어(10)의 일단을 인장판(14)에 고정하고, 인장기(17)로 와이어(10)를 적절히 인장시킨 후 너트(16)로 조여 인장 상태를 유지하고, 하형(12)에 콘크리트를 채운 후 상형(11)을 조립하고, 림(18)을 통하여 상형(11)과 하형(12)을 회전시키면서 원심력으로 콘크리트를 양생하고, 돌출된 와이어(10)를 절단하여 전주를 완성한다.Looking at the work process, after placing the plurality of wires 10 in the longitudinal direction, and wound around the spiral wound around the wire to form a frame, by heating and pressing the ends of the wires arranged in the longitudinal direction in the formed frame head (10a) is formed, the mold release agent is applied to the upper mold 11 and the lower mold 12, and the lower mold 12 is attached to the lower mold 12 in a state in which a horse plate 13 and a sphere plate 19 are attached to both ends of the wire 10. It is seated, and one end of the wire 10 is fixed to the tension plate 14, the wire 10 is properly tensioned with the tensioner 17, and then tightened with a nut 16 to maintain the tension state, and the lower mold 12 After filling the concrete into the upper mold (11), while rotating the upper mold (11) and the lower mold (12) through the rim 18, curing the concrete by centrifugal force, cutting the protruding wire (10) to complete the pole do.
이때 말구판(13)과 인장판(14)은 와이어(10)의 헤드(10a)가 통과할 정도의 구멍을 지니고, 인장판(14) 외측에 장착되는 부호 14′의 고정판은 직경이 다른 피넛(peanut) 형상의 구멍을 지닌다. 와이어(10)의 헤드(10a)가 고정판(14′)의 큰 직경부를 통과한 후 고정판(14′)을 약간 회전시키면 헤드(10a)가 작은 직경부에 도달하여 와이어(10)를 구속한다.At this time, the horse plate 13 and the tension plate 14 has a hole enough to pass through the head 10a of the wire 10, and the fixed plate 14 'mounted on the outside of the tension plate 14 has a different diameter nut (peanut) has a hole in the shape. If the head 10a of the wire 10 passes through the large diameter portion of the fixing plate 14 'and then rotates the fixing plate 14' slightly, the head 10a reaches the small diameter portion and restrains the wire 10.
이와 같이 말구판(13)의 구멍이 와이어(10)의 직경보다 커지는 구성에 의해 그 틈새로 콘크리트나 수분이 누출되기 때문에 제품의 말구 형상이 불량해지고 이에 따라 마무리 작업에 많은 시간을 요한다.In this way, since the hole of the horseboard 13 is larger than the diameter of the wire 10, concrete or water leaks into the gap, so that the horseshoe shape of the product is poor, thus requiring a lot of time for finishing work.
이를 방지하기 위해 말구판(13) 내측면에서 구멍의 틈새에 종이 등의 마개를 끼우기도 하는데 콘크리트나 수분의 누출이 상당히 감소되기는 하지만 별도의 작업자를 둠으로써 공수가 증가하는 것은 물론 양생 후 다시 종이를 제거하고 마무리하는 공정의 작업성이 개선되지 않는다.To prevent this, a stopper such as paper is inserted into a gap in the hole on the inner side of the horseboard (13), but the leakage of concrete or water is considerably reduced, but by adding a separate worker, the airborne increases as well as paper after curing. The workability of the process of removing and finishing does not improve.
따라서, 본 발명은 상술한 종래 기술의 단점을 해결하기 위한 것으로서, 송전을 위한 전선을 지지하는 전주의 제조현장에서 원심 주조에 이용되는 금형장치의 말구판을 개선하여 제조공정을 단순화하면서도 제품의 고품질을 유지하는 전주 금형의 말구판 구조를 제공하는데 있다.Accordingly, the present invention is to solve the above-mentioned disadvantages of the prior art, by improving the final plate of the mold apparatus used for centrifugal casting in the manufacturing site of the electric pole for supporting the electric wire for power transmission while simplifying the manufacturing process and high quality of the product It is to provide a structure of the horse plate of the pole mold to maintain the.

이와 같은 목적을 달성하기 위해 본 발명에 따른 전주 금형의 말구판 구조는 상형(11), 하형(12), 말구판(30), 원구판(19)으로 이루어지는 공간 상에서 와이어(10)로 형성한 프레임을 인장한 상태로 콘크리트에 몰딩시켜 전주를 성형하는 장치에 있어서: 상기 말구판(30)은 와이어(10)의 헤드(10a)가 통과하는 순간 탄성 변형되고 헤드(10a)가 통과한 후 와이어(10)에 밀착되도록 탄성 복귀하는 소재를 사용하여 성형되는 것을 특징으로 한다.In order to achieve the above object, the horse plate structure of the electroforming die according to the present invention is formed of a wire 10 on a space consisting of an upper die 11, a lower die 12, a horse plate 30, and a sphere plate 19. In the apparatus for molding a pole by molding the concrete in the tensioned state of the frame: the horseboard 30 is elastically deformed at the moment when the head (10a) of the wire 10 passes and the wire after the head (10a) passes It is characterized in that it is molded using a material that elastically returns to be in close contact with (10).
이하, 본 발명의 바람직한 실시예를 첨부된 도면에 의거하여 상세하게 설명한다.Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.
도 2는 본 발명에 따른 전주 금형장치의 요부를 나타내는 구성도가 도시된다.Figure 2 is a block diagram showing the main portion of the electroforming mold apparatus according to the present invention.
본 발명은 상형(11), 하형(12), 말구판(30), 원구판(19)으로 이루어지는 공간 상에서 와이어(10)로 형성한 프레임을 인장한 상태로 콘크리트에 몰딩시켜 전주를 성형하는 장치에 적용한다. 상형(11), 하형(12) 및 원구판(19)의 구성은 종래와 동일하게 하고 말구판(30)을 개선한다. 인장판(14), 스크류(15), 너트(16), 인장기(17) 등을 이용하여 와이어(10)를 인장하는 구성도 종래와 동일성을 유지하는 것이 가능하다.The present invention is a device for molding a pole by molding the concrete formed in the tension state of the frame formed by the wire 10 in the space consisting of the upper mold (11), lower mold (12), horse plate 30, spherical plate 19 Applies to The structure of the upper mold | type 11, the lower mold | type 12, and the spherical plate 19 is made the same as before, and the horse plate 30 is improved. The structure in which the wire 10 is tensioned using the tension plate 14, the screw 15, the nut 16, the tensioner 17, and the like can also maintain the same identity as the conventional art.
이때, 본 발명에 따르면 말구판(30)은 와이어(10)의 헤드(10a)가 통과하는 순간 탄성 변형되고 헤드(10a)가 통과한 후 와이어(10)에 밀착되도록 탄성 복귀하는 소재를 사용하여 성형된다. 즉, 말구판(30)에서 와이어(10)가 통과되는 구멍이신축적으로 변형되도록 하면 틈새가 줄어들고 기밀성을 유지할 수 있어 성형중 콘크리트나 수분의 누출이 방지된다.At this time, according to the present invention, the horseshoe plate 30 is elastically deformed at the moment when the head 10a of the wire 10 passes and uses a material that elastically returns to closely contact the wire 10 after the head 10a passes. Molded. That is, when the hole through which the wire 10 passes through the horseboard 30 is deformed elastically, the gap can be reduced and airtightness can be maintained to prevent leakage of concrete or moisture during molding.
도 3은 본 발명에 따른 말구판의 구성을 나타내는 단면도가 도시된다.Figure 3 is a cross-sectional view showing the configuration of a horse plate according to the invention.
본 발명의 말구판(30)은 외부판(31)과 내부판(32)으로 구성되는데, 상호 접합시키지 않은 상태로 사용하는 것이 가능하다. 외부판(31)은 콘크리트의 성형압력을 지탱하기 위한 강도를 지니는 철판재로 성형하고, 내부판(32)은 와이어(10)의 기밀성을 보장하기 위한 탄성을 지니는 고무재로 성형한다.The horseshoe plate 30 of the present invention is composed of an outer plate 31 and an inner plate 32, but can be used without being bonded to each other. The outer plate 31 is formed of an iron plate having strength to support the molding pressure of concrete, and the inner plate 32 is formed of a rubber material having elasticity to ensure the airtightness of the wire 10.
내부판(32)에서 외측에는 플랜지(32c)를 형성하여 외부판(31)과 직경이 같아지도록 하는데, 이 부분은 상형(11) 및 하형(12)에 삽입되어 성형시 콘크리트의 압력을 지탱하는 동시에 기밀도 유지한다. 플랜지(32c)의 두께는 성형되는 전주의 크기에 따라 달라질 수 있으나 통상 8㎜ 이상으로 하면 적절하다.In the inner plate 32 to form a flange (32c) on the outside to have the same diameter as the outer plate 31, this portion is inserted into the upper mold 11 and lower mold 12 to support the pressure of the concrete during molding At the same time, it also maintains confidentiality. The thickness of the flange 32c may vary depending on the size of the pole being formed, but is usually appropriate if it is 8mm or more.
이때, 상기 말구판(30)의 내부판(32)은 대경부(32a)의 내측단에 소정의 길이에 걸쳐 소경부(32b)를 지닌다. 내측면을 곡면으로 하고 소경부(32b)의 두께를 일정하게 하는 형상으로 금형을 제작하여 말구판(30)을 성형한다. 성형 소재는 고무 대신 연질 합성수지를 사용하는 것도 가능한데 어느 경우에나 내화학성, 내마모성도 지니는 것을 요한다.At this time, the inner plate 32 of the horse plate 30 has a small diameter portion 32b on the inner end of the large diameter portion 32a over a predetermined length. The inner surface is made curved and a mold is produced in a shape in which the thickness of the small diameter portion 32b is made constant, thereby forming the horse plate 30. It is also possible to use flexible synthetic resins instead of rubber, which requires chemical and abrasion resistance in either case.
도 3에서 와이어(10)가 말구판(30)의 소경부(32b)와 대경부(32a)를 통과하는 상태를 알 수 있다. 대경부(32a)와 소경부(32b)의 치수는 와이어(10)의 직경에 비례하는데, 일예로 와이어(10)가 7.4ø인 경우 각각 10㎜, 24㎜ 이내로 한다. 헤드(10a)의 크기를 작게 할수록 이러한 치수 차이는 더욱 축소된다.In FIG. 3, it can be seen that the wire 10 passes through the small diameter portion 32b and the large diameter portion 32a of the horse plate 30. The dimensions of the large diameter portion 32a and the small diameter portion 32b are proportional to the diameter of the wire 10. For example, when the wire 10 is 7.4 °, the diameter is set within 10 mm and 24 mm, respectively. The smaller the size of the head 10a is, the smaller the dimensional difference becomes.
본 발명의 말구판(30)을 이용하여 전주를 제작하는 경우에도 전반적인 공정은 전술한 바와 동일하지만 말구판(30)의 소경부(32b)에 종이를 끼우는 작업이 불필요할 뿐아니라 이형제를 적게 도포하여도 제품의 분리가 쉬우면서 표면이 비교적 매끄러워 마무리 공정을 신속하게 완료할 수 있다.Even when manufacturing a pole using the horse plate 30 of the present invention, the overall process is the same as described above, but it is not necessary to insert the paper in the small diameter portion (32b) of the horse plate 30, as well as to apply less release agent Even though the product is easy to separate and the surface is relatively smooth, the finishing process can be completed quickly.
상술한 바와 같은 구성 및 작용에 따른 본 발명의 전주 금형의 말구판 구조는 송전을 위한 전선을 지지하는 전주의 제조현장에서 원심 주조에 이용되는 금형장치의 말구판을 개선하여 제조공정을 단순화하면서도 제품의 고품질을 유지하는 효과가 있다.The horse plate structure of the electric pole mold of the present invention according to the configuration and action as described above improves the horse plate of the mold apparatus used for centrifugal casting in the manufacturing site of the electric pole supporting the wire for power transmission, while simplifying the manufacturing process It is effective to maintain high quality.
