In general, as shown in Figure 1, the corner corner connecting angle, the two flat plate parts 30 are connected to each other at right angles to form an angle shape L-shaped cross-section and the wedge 20 in the flat plate 30 Is formed with a plurality of wedge holes (30a) is inserted, as shown in Figure 2, coupled to the outside of the corner portion of the formwork 10 connected to each other at right angles, and serves to support the formwork (10).

이때, 상기 거푸집 코너연결용 앵글(A)은 길이가 긴 강철재 스트립의 측면을 상호 용접하여 제작되며, 상기 쐐기공(30a)은 별도의 가공을 통해 형성된다. 또한, 상기 거푸집(10)은 둘레면에 상기 쐐기공(11a)과 대응되는 쐐기공(30a)이 형성된 유로폼(11)을 조립하여 제작된다.At this time, the formwork corner connection angle (A) is produced by welding the side of the long strip of steel material mutually, the wedge hole (30a) is formed through a separate process. In addition, the formwork 10 is manufactured by assembling the flow path 11 is formed with a wedge hole (30a) corresponding to the wedge hole (11a) on the circumferential surface.

따라서, 상기 거푸집 코너연결용 앵글(A)의 평판부(30) 외측면이 상기 거푸집(10)의 코너부분에 밀착되도록 배치하고, 거푸집(10)을 이루는 유로폼(11)에 형성된 쐐기공(30a)과, 거푸집 코너연결용 앵글(A)에 형성된 쐐기공(11a)을 관통하도록 쐐기(20)를 끼운 후, 별도의 보조쐐기(23)를 상기 쐐기(20)의 관통공(21)에 끼워 고정하므로써, 거푸집(10)과, 거푸집 코너연결용 앵글(A)이 상호 움직이지 않도록 고정할 수 있다.Therefore, the outer surface of the plate portion 30 of the formwork corner connection angle (A) is disposed so as to be in close contact with the corner portion of the formwork 10, the wedge 30a formed in the flow path 11 forming the formwork (10) ) And the wedge 20 to pass through the wedge hole 11a formed in the die corner connection angle A, and then a separate auxiliary wedge 23 is inserted into the through hole 21 of the wedge 20. By fixing, the formwork 10 and the formwork corner connecting angle A can be fixed so as not to mutually move.

그런데, 이러한 거푸집 코너연결용 앵글(A)은 강철로 제작되므로, 무게가 많이 나가서 운반이나 취급이 매우 어려운 문제점이 있었다. By the way, since the formwork corner connection angle (A) is made of steel, there was a problem that a lot of weight is very difficult to carry or handle.

또한, 이러한 거푸집 코너연결용 앵글(A)은 판형상으로 이루어진 측면에 쐐기공(30a)이 형성되며, 상기 쐐기공(30a)에 끼워진 쐐기(20)를 이용하여 거푸집(10)을 고정하므로, 쐐기공(30a)에 하중이 집중되므로, 장시간 사용할 경우, 쐐기공(30a)을 중심으로 파열이 발생되어 수명이 짧아지게 되는 문제점이 있었다.In addition, the formwork corner connection angle (A) is formed with a wedge hole (30a) on the side made of a plate shape, and fixed the formwork (10) by using the wedge 20 fitted in the wedge hole (30a), Since the load is concentrated in the wedge hole (30a), when used for a long time, there was a problem that the burst occurs around the wedge hole (30a), the life is shortened.

특히, 상기 쐐기(20)는 거푸집 코너연결용 앵글(A)의 평판부(30) 내측에서 상기 쐐기공(30a)을 관통하도록 끼워져, 헤드부(22)가 평판부(30)의 내측면에 밀착되게 설치된다. 따라서, 거푸집 코너연결용 앵글(A)을 분리해 내기 위해 상기 쐐기(20)를 빼낼 때 작업자가 쐐기(20)의 헤드부(22)를 잡기 어려운 문제점이 있었다.In particular, the wedge 20 is inserted so as to penetrate the wedge hole 30a inside the flat plate portion 30 of the die corner connecting angle (A), the head portion 22 to the inner surface of the flat plate portion 30 It is installed closely. Therefore, when the wedge 20 is pulled out to remove the formwork corner connection angle A, it is difficult for an operator to grasp the head portion 22 of the wedge 20.

본 발명은 상기의 문제점을 해결하기 위한 것으로서, 무게가 가벼워 운반이나 취급이 용이하며, 강도를 보강하여 수명을 연장시킬 수 있도록 된 새로운 구조의 거푸집 코너연결용 앵글을 제공함에 그 목적이 있다.The present invention has been made in view of the above-mentioned problems, and its object is to provide an angle for formwork corner connection with a new structure that is light in weight and easy to transport or handle, and can extend its life by reinforcing strength.

도 3 및 도 4에 의하면, 본 발명에 따른 거푸집 코너연결용 앵글은, 2개의 평판부(30)가 상호 직각되도록 연결되어 단면이 L자인 앵글형상으로 구성되며 상기 평판부(30)에는 쐐기(20)가 삽입되는 쐐기공(30a)이 다수개 형성되어, 평판부(30)의 외측면이 거푸집(10)의 코너부분에 밀착되도록 고정설치되는 것은 종래와 동일하다. According to FIG. 3 and FIG. 4, the formwork corner connection angle according to the present invention is connected to each other so that the two flat plate portions 30 are formed at right angles and have an L-shaped cross section. A plurality of wedge holes 30a into which 20 is inserted are formed, and the outer surface of the flat plate portion 30 is fixedly installed to be in close contact with the corner portion of the formwork 10 as in the prior art.

그리고, 본 발명에 따르면, 상기 거푸집 코너연결용 앵글(A)은 알루미늄을 압출성형한 후, 평판부(30)에 상기 쐐기공(30a)을 형성하여 제작된다.In addition, according to the present invention, the die corner connecting angle (A) is produced by forming the wedge hole (30a) in the flat plate 30, after extrusion molding aluminum.

이때, 상기 평판부(30)는 상기 거푸집(10)에 밀착되는 외측면이 평면으로 이루어지며, 외측면의 반대쪽 면, 즉, 내측면의 중간부에는 평판부(30)의 내측방향으로 돌출되어 다른 부위에 비해 두께가 두꺼운 돌출부(31)가 평판부(30)의 길이방향을 따라 길게 형성되며, 상기 쐐기공(30a)은 상기 돌출부(31)에 형성된다. At this time, the flat plate 30 is made of a flat outer surface that is in close contact with the formwork 10, the opposite side of the outer surface, that is, the middle portion of the inner surface protrudes in the inner direction of the flat plate 30 The protruding portion 31 having a thicker thickness than that of other portions is formed along the longitudinal direction of the flat plate portion 30, and the wedge hole 30a is formed in the protruding portion 31.

상기 돌출부(31)는 거푸집 코너연결용 앵글(A)을 압출형성할 때, 금형에 의해 평판부(30)에 일체로 형성되며, 상기 쐐기공(30a)은 상기 돌출부(31)의 중앙부에 형성된다.The protrusion 31 is integrally formed in the flat plate portion 30 by a mold when forming the die corner connecting angle (A), the wedge hole (30a) is formed in the central portion of the protrusion 31 do.

따라서, 상기 거푸집 코너연결용 앵글(A)을 평판부(30)의 외측면이 상기 거푸집(10)의 코너부분에 밀착되도록 배치하고, 거푸집(10)을 이루는 유로폼(11)에 형성된 쐐기공(11a)과 거푸집 코너연결용 앵글(A)에 형성된 쐐기공(30a)을 관통하도록, 평판부(30)의 내측에서 쐐기(20)를 끼운 후, 별도의 보조쐐기(23) 상기 쐐기(20)의 관통공(21)에 끼워 고정하므로써, 거푸집(10)과, 거푸집 코너연결용 앵글(A)이 상호 움직이지 않도록 고정할 수 있다.Therefore, the formwork corner connecting angle (A) is disposed so that the outer surface of the plate portion 30 is in close contact with the corner portion of the formwork 10, the wedge hole formed in the flow path 11 forming the formwork (10) 11a) and after inserting the wedge 20 in the inner side of the flat plate 30 so as to penetrate the wedge hole 30a formed in the die corner connecting angle (A), a separate auxiliary wedge 23, the wedge 20 By inserting and fixing in the through hole 21, the formwork 10 and the formwork corner connecting angle A can be fixed so as not to move with each other.

이와같이 구성된 거푸집 코너연결용 앵글(A)은 알루미늄을 압출성형하여 제작되므로, 무게가 가벼워, 운반 및 취급이 용이한 장점이 있다.The die corner connecting angle (A) configured as described above is manufactured by extrusion molding aluminum, so that the weight is light, and there is an advantage of easy transportation and handling.

또한, 상기 평판부(30)의 내측면에는 돌출부(31)가 구비되고, 상기 쐐기공(30a)이 돌출부(31)에 형성되므로, 돌출부(31)에 의해 쐐기공(30a)의 강도가 보강되어 쐐기공(30a)을 중심으로 파열이 발생되는 것을 방지하고, 거푸집 코너연결용 앵글(A)의 수명을 연장시킬 수 있는 장점이 있다.In addition, since the protrusion 31 is provided on the inner surface of the flat plate 30, and the wedge hole 30a is formed in the protrusion 31, the strength of the wedge hole 30a is reinforced by the protrusion 31. There is an advantage to prevent the occurrence of the tear around the wedge hole (30a), and to extend the life of the die corner connection angle (A).

특히, 상기 돌출부(31)가 평판부(30)의 내측면에 형성되고 쐐기공(30a)이 상기 돌출부(31)에 형성됨에 따라, 평판부(30)의 내측에서 쐐기공(30a)에 쐐기(20)를 끼우면, 쐐기(20)의 헤드부(22)가 상기 돌출부(31)에 닿아, 헤드부(22)의 둘레면이 평판부(30)의 내측면으로부터 이격된다. 따라서, 작업자가 쐐기공(30a)에 쐐기(20)를 끼우거나 빼낼 때, 사용자가 쐐기(20)의 헤드부(22)를 잡을 수 있는 공간이 확보되므로, 쐐기(20)를 쐐기공(30a)에 끼우거나 빼내는 작업이 매우 용이해지는 장점이 있다.In particular, as the protrusions 31 are formed on the inner surface of the flat plate 30 and the wedge holes 30a are formed on the protrusions 31, wedged the wedge holes 30a on the inside of the flat plate 30. When the 20 is fitted, the head portion 22 of the wedge 20 touches the protruding portion 31 so that the circumferential surface of the head portion 22 is spaced apart from the inner side surface of the flat plate portion 30. Therefore, when the operator inserts or pulls the wedge 20 into or out of the wedge hole 30a, a space for the user to hold the head portion 22 of the wedge 20 is secured, so that the wedge 20 is wedge hole 30a. ) Is very easy to insert or take out.

도 5 및 도 6은 본 발명에 따른 다른 실시예를 도시한 것으로, 상기 평판 부(30)의 내측면에는 상기 쐐기공(30a)의 양측에 위치되는 돌기(32)가 평판부(30)의 길이방향을 따라 길게 형성된다. 5 and 6 illustrate another embodiment according to the present invention, wherein the projections 32 positioned at both sides of the wedge hole 30a are formed on the inner surface of the plate portion 30 of the plate portion 30. It is formed long along the longitudinal direction.

상기 돌기(32)는 거푸집 코너연결용 앵글(A)을 압출제작할 때, 평판부(30)와 일체로 형성되는 것으로, 하중이 작용되는 쐐기공(30a)의 측면을 보강함과 동시에, 상기 평판부(30)의 내측에서 쐐기공(30a)에 쐐기(20)를 끼울 때, 쐐기(20)의 헤드부(22)가 상기 돌기(32)에 닿아 헤드부(22)가 평판부(30)의 내측면으로부터 이격되도록 한다.The protrusion 32 is formed integrally with the flat plate portion 30 when the die corner connecting angle A is extruded, and reinforces the side surface of the wedge hole 30a to which the load is applied. When the wedge 20 is fitted into the wedge hole 30a from the inside of the part 30, the head part 22 of the wedge 20 touches the protrusion 32 so that the head part 22 is the flat plate part 30. Spaced apart from the inner surface of the substrate.

따라서, 쐐기공(30a)에 파열이 발생되는 것을 방지하여 거푸집 코너연결용 앵글(A)의 수명을 연장함과 동시에, 평판부(30)의 내측면과 헤드부(22)의 사이에 공간을 형성하여, 작업자가 쐐기(20)를 쐐기공(30a)에 끼우거나 빼내는 작업이 용이해지는 장점이 있다.Therefore, the tear is prevented from occurring in the wedge hole 30a, thereby prolonging the life of the formwork corner connecting angle A, and providing a space between the inner surface of the plate portion 30 and the head portion 22. By forming, there is an advantage that the operator is easy to insert or pull the wedge 20 into the wedge hole (30a).

특히, 이러한 거푸집 코너연결용 앵글(A)은 돌출부(31)가 형성되어 평탄부(30)의 배면 중앙부 전체의 두께가 두꺼워지는 제1 실시예와 달리, 상기 쐐기공(30a)의 양측에만 돌기가 형성되므로, 재료를 절감할 수 있을 뿐 아니라, 무게를 최소화하여, 운반 및 취급이 더욱 용이해지는 장점이 있다.In particular, the die corner connecting angle (A), unlike the first embodiment in which the protrusion 31 is formed so that the thickness of the entire rear center portion of the flat portion 30 is thick, protruding only on both sides of the wedge (30a) Since it is formed, not only can the material be saved, but also minimizes the weight, there is an advantage that the handling and handling is more easy.
