Abstract

A fastener for a concrete form plate is provided to maintain alignment of a formwork by putting over reinforcement to adhere to the outer surface of a concrete formwork. A pair of coupling projections are parallelly formed at the tip-end part of a fastener main body(1) to have a cross section of a U-shape by folding a metal plate and is maintained at a right angle direction to a coupling gap. A fastening hole(2,2a) having the same standard with a fastening pin insertion hole is formed on a horizontal line. One side of the fastening hole is formed on the central line of the top and bottom of inner circumference. A pair of guide projections are formed to be protruded to the central part and are coupled to a guide groove(3a) formed at the outer circumference of the fastening pin(3) inserted into the fastening hole. The fastening pin is slid without being separated from one side of the fastening hole. A through hole(1e) is formed on the floor of a support wall(1d) vertically formed at the opposite side of the coupling projection part. A tensioning device(4) which has a tapered shape and in which a hanging groove(4a) is formed at the inside of the lower end part is inserted.

Description

콘크리트 형틀 보강체 체결구{A FASTENER FOR CONCRETE FORM PLATE}Concrete form reinforcement fasteners {A FASTENER FOR CONCRETE FORM PLATE}

본 발명은 콘크리트 형틀을 설치할 때 수직으로 배치된 형틀이 평탄하게 유지될 수 있도록 형틀 외측면에 밀착하도록 보강체를 덧대어서 형틀이 가즈런하게 유지되도록 하는 체결구에 관한 것으로 보다 구체적인 것은 체결구 본체의 선단부에 형틀 틀체에 결합하는 결합부가 형성되어 체결핀이 장치되고 결합부 반대측에 보강체를 긴장시키는 긴장구가 삽입되어 구성되는 것을 특징으로 한다.The present invention relates to a fastener for adding a reinforcing body to be in close contact with the outer surface of the mold so that the mold vertically maintained when installing the concrete mold to maintain a flat shape, and more specifically, The front end portion is formed with a coupling portion that is coupled to the mold frame, the fastening pin is provided, characterized in that it is configured by inserting the tension sphere for tensioning the reinforcement on the opposite side of the coupling portion.

종래의 형틀 보강체 체결구는 체결구본체와 형틀 틀체가 결합되는 곳에 별도의 웨지핀이 삽입되는 구성이고 웨지핀에 연결되는 볼트 머리에 긴장용 와셔를 개재하는 것으로 사용이 매우 불편이 결점이 있었다.Conventional mold reinforcement fastener is a configuration that the separate wedge pin is inserted where the fastener main body and the frame frame is coupled and there is a drawback to use the tension washer in the bolt head connected to the wedge pin was very inconvenient.

본 발명은 상기와 같은 종래의 결점을 해소시키기 위한 것이다.The present invention is to solve the above conventional drawbacks.

본 발명은 체결구 본체의 선단 결합부에 결합공을 형성하여 체결핀을 장치하고 선단 결합부 반대측에 상하로 관통공을 형성하여 쇄기형상의 긴장구를 장치하여서 되는 것이다.The present invention is to form a coupling hole in the front end coupling portion of the fastener main body to provide a fastening pin and to form a through hole up and down on the opposite side of the front coupling portion is equipped with a wedge-shaped tension ball.

이와 같이 된 본 발명은 형틀(5)을 설치하고 인접하는 두 형틀(5)의 형틀 틀체(5a)외면으로 체결구본체(1)의 결합돌부(1a)를 삽입하여 체결공(2)(2a)을 형틀 틀체(5a)에 형성된 체결핀삽입공(5b)과 일직선상에 오도록 한 다음 일측 체결공(2)에 장치한 체결핀(3)을 밀어서 체결공과 형틀의 체결핀삽입공(5b)을 체결핀(3)으로 결속하고 받침벽(1d) 내면에 삽입된 긴장구(4)의 하단부 걸림홈(4a)을 체결구본체의 바닥에 결합시키면 긴장구(4)가 경사지게 장치되므로 이때 체결구본체(1) 상면과 긴장구(4)사이에 형성된 간격에 4각형관체로 된 보강체(6)를 가설하고 긴장구(4) 하단의 걸림홈(4a)을 바닥에서 분리하여 통공부(1e)로 삽입하면 받침벽(1d) 내면을 따라 긴장구(4)가 하향하면서 경사면(4b)이 보강체(6)를 가압하여 형틀 틀체에 밀착유지하게 된다.According to the present invention as described above, the mold 5 is installed, and the coupling protrusion 1a of the fastener main body 1 is inserted into the outer surface of the mold frame 5a of two adjacent molds 5 to fasten the holes 2 and 2a. ) Is in line with the fastening pin insertion hole (5b) formed in the mold frame (5a) and then push the fastening pin (3) installed in one fastening hole (2) by the fastening hole and the fastening pin insertion hole (5b) of the mold To the bottom of the fastener main body by engaging the bottom locking groove 4a of the fastener 4 inserted in the inner surface of the support wall 1d and fastening the fastener 4 at an angle, In the gap formed between the upper surface of the sphere body (1) and the tension sphere (4), a reinforcement (6) made of a rectangular tube body is hypothesized, and the engaging groove (4a) of the lower end of the tension sphere (4) is separated from the bottom through hole ( 1e), the inclined surface 4b presses the reinforcement 6 while keeping the tension ball 4 downward along the inner surface of the support wall 1d, thereby maintaining close contact with the mold frame.

그러므로 형틀에 보강체가 밀착하여 형틀을 지지하는 효과를 내게 되고 해체시에는 결합시와 반대로 긴장구(4)를 밑에서 위로 강제 이동시켜 분리하고 보강체(6)를 들어낸 후 체결구본체(1)의 결합돌부(1a)에 장치된 체결핀(3)을 뽑아서 분리하면 된다.Therefore, the reinforcement is in close contact with the mold to support the mold, and when dismantling, the tension sphere 4 is forcedly moved from the bottom to the upper side as opposed to the time of assembly, and the reinforcing body 6 is lifted up, and then the fastener main body 1 It is enough to pull out the fastening pin (3) provided in the engaging projection (1a) of the.

따라서 본 발명은 간편하고 편리한 방법으로 형틀과 보강체를 결합하고 분리할 수 있는 효과를 얻게 되며 작업이 능률적으로 되는 이점을 얻도록 되는 장점이 있다.Therefore, the present invention has the advantage of obtaining the effect of combining and separating the mold and the reinforcement in a simple and convenient way, and the work is efficient.
