Description

기초파일용 강관의 상단 배근구조 {STEEL REINFORCING CONNECT STRUCTURE FOR PILE}Upper reinforcement structure of steel pipe for foundation pile {STEEL REINFORCING CONNECT STRUCTURE FOR PILE}

본 발명은 교량 등 토목건축의 기초공사시 매설되는 강관의 상부로 기초콘크리트를 위한 배근구조에 관한 것으로서, 특히 강관 상단에 씌워지는 덮개판 및 강관 내부로 위치되어 상기 덮개판을 지지시키는 보강판의 고정을 용이하고도 안정되게 하고, 상기 덮개판상에 용이한 배근이 이루어지도록 한 기초파일용 강관의 상단 배근구조에 관한 것이다.The present invention relates to the reinforcement structure for the foundation concrete to the upper part of the steel pipe buried during the foundation construction of civil construction, such as bridges, in particular of the cover plate which is covered on the top of the steel pipe and the reinforcement plate for supporting the cover plate The present invention relates to a top reinforcement structure of a steel pipe for a basic pile, which is easy and stable to fix and facilitates easy reinforcement on the cover plate.

일반적으로 교량 등의 공사시에는 그 기초공사로서 대직경을 지니는 강관을 매설하게 되고, 매설된 강관의 상부로는 상기 강관과 연결되도록 기둥용 콘크리트타설이 이루어진다.In general, during the construction of bridges, etc., as a foundation work, steel pipes having a large diameter are buried, and the upper part of the embedded steel pipes is made of concrete for pillars to be connected to the steel pipes.

이를 위해 종래에는 도 1에서와 같이 강관(1)의 상단 개구부에 덮개판(2)이 구비되고, 상기 덮개판(2)이 지지되도록 덮개판(2)의 하단에는 강관(1) 내부로 위치되는 십자형태의 보강판(3)이 설치되며, 상기 덮개판(2)의 상단면에는 다수의 철근(4)이 용접 등의 방법으로 연결되는 구성이었다.To this end, a cover plate 2 is provided in the upper opening of the steel pipe 1, as shown in FIG. 1, and is positioned inside the steel pipe 1 at the lower end of the cover plate 2 so that the cover plate 2 is supported. The reinforcing plate (3) of the cross shape is to be installed, the upper surface of the cover plate (2) was a configuration in which a plurality of reinforcing bar (4) is connected by a method such as welding.

즉, 덮개판(2)의 하단으로 보강판(3)을 용접으로 연결하거나 강관(1)의 내면에 보강판(3)을 용접으로 고정하여 상기 보강판(3)이 강관(1) 내부로 인입되고 덮개판(2)이 강관(1)의 상단 테두리면에 걸쳐지는 상태로 설치한 후, 상기 덮개판(2) 및 강관(1)의 외주면에 다수의 철근(4)이 소정간격으로 용접되도록 하고, 상기 철근(4)을 통해 배근하여 콘크리트타설이 이루어지도록 하였다.That is, the reinforcing plate 3 is welded to the lower end of the cover plate 2, or the reinforcing plate 3 is fixed to the inner surface of the steel pipe 1 by welding so that the reinforcing plate 3 is moved into the steel pipe 1. After retracting and installing with the cover plate 2 covering the upper rim surface of the steel pipe 1, a plurality of reinforcing bars 4 are welded to the outer circumferential surface of the cover plate 2 and the steel pipe 1 at predetermined intervals. And to reinforce through the reinforcing bar (4) was to be concrete pouring.

그런데 이러한 구조는 덮개판(2), 보강판(3), 철근(4)이 각각 용접에 의해 연결 고정되는 것에 의해 소정의 하중에 견디어내지 못하고, 용접점탈락의 염려를안게 되며, 용접부위의 심한 부식 등에 의해 부실공사가 될 수 있는 폐단이 있었다.However, the structure of the cover plate 2, the reinforcement plate 3, the reinforcing bar 4 is fixed by welding, respectively, so that it cannot endure a predetermined load and there is a fear of welding spot dropping. There was a possibility of poor construction due to severe corrosion.

특히 철근(4)은 덮개판(2) 및 강관(1)의 외주면을 통해 용접됨으로써 수직하중에 매우 취약하게 되는 문제점을 안고 있었다.In particular, the reinforcing bar 4 had a problem that is very vulnerable to vertical load by welding through the outer peripheral surface of the cover plate 2 and the steel pipe (1).

이러한 종래의 문제점을 해결하기 위해 대한민국 공개실용신안 공개번호 97-18138호 및 97-39408호에는 강관 말뚝용 덮개판에 관한 보다 개선된 기술이 제안된 바 있다.In order to solve this conventional problem, the Republic of Korea Utility Model Publication No. 97-18138 and 97-39408 has been proposed a more improved technology for the cover plate for steel pipe piles.

즉, 상기 공개실용신안 공개번호 97-18138호는 덮개판의 상부면 둘레에 철근을 일체로 스터드용접하여 부착하거나 상기 덮개판상에 나사결합수단을 용접하여 상기 나사결합수단을 통해 철근이 나사결합되는 기술이고, 공개실용신안 공개번호 97-39408호는 덮개판의 저면에 부설되는 보강판이 볼트결합되도록 덮개판 및 보강판에 체결공을 형성하고 보강판의 외측에도 체결홈을 형성하여 강관 대응위치의 체결공을 통해 볼트로 결합고정시키거나, 덮개판상에 베이스관을 용접하여 철근이 상기 베이스관 일측으로 설치된 체결볼트에 의해 고정되는 기술이다.That is, the Utility Model Publication No. 97-18138 is attached to the reinforcement around the upper surface of the cover plate integrally stud welding or welding the screwing means on the cover plate is screwed through the screwing means Published Utility Model Publication No. 97-39408 forms a fastening hole in the cover plate and the reinforcement plate so that the reinforcement plate attached to the bottom of the cover plate is bolted, and a fastening groove is formed in the outer side of the reinforcement plate so that It is a technology that is fixed by a fastening bolt installed to one side of the base tube by fixing the bolt through the fastening hole or by welding the base tube on the cover plate.

그런데 상기 공개실용신안 공개번호 97-18138호의 구성은 철근이 덮개판의 외주면에 용접되는 것이 아니라 덮개판의 상부면에 용접되는 것에 의해 어느정도 하중문제를 해결할 수 있겠으나 용접점 탈락 등의 종래의 제반문제를 그대로 안게 되고, 보다 진보한 방법으로 덮개판상에 별도의 나사결합수단을 용접한 후 상기 나사결합수단을 통해 철근이 나사결합으로 연결되게 하였으나 이 또한 별도의 나사결합수단을 구비하여 각각 용접하여야 하고 이에 또 다시 철근을 나사조립시키게 되는 까닭에 부품수의 증가 및 조립작업의 공수가 늘게 되는 등으로 효율적인 작업이 이루어지지 못하는 폐단이 있었다.However, the configuration of the Korean Utility Model Publication No. 97-18138 can solve the load problem to some extent by welding the reinforcing bar to the upper surface of the cover plate rather than to the outer circumferential surface of the cover plate. The problem remains, and in a more advanced way, a separate screwing means is welded onto the cover plate, and then the reinforcing bars are connected by screwing through the screwing means. In addition, because the rebar is screwed again, there was a discontinuity that the efficient work cannot be performed due to the increase in the number of parts and the increase in the number of assembly work.

또한, 공개실용신안 공개번호 97-39408호의 구성 역시 덮개판 및 강관에 각각 체결홈을 형성하여 덮개판 및 보강판이 강관을 통해 나사체결되는 복잡한 조립구조를 이루게 되고, 철근을 연결시키기 위해서는 덮개판상에 각각의 베이스관을 용접하고 상기 베이스관에 삽입된 철근을 고정시키기 위해 베이스관 외측에서 또 다시 볼트체결 작업이 요구되는 등 부품수의 증가와 함께 그 조립공수가 대폭늘게 되는 등의 여러 폐단이 도출되었다.In addition, the configuration of Korean Utility Model Publication No. 97-39408 also forms a fastening groove in the cover plate and the steel pipe, respectively, to form a complicated assembly structure in which the cover plate and the reinforcement plate are screwed through the steel pipe, and in order to connect the reinforcing bar on the cover plate. Several closures have been drawn, such as the increase in the number of parts and the increase in the number of parts, such as the need for bolting work again outside the base pipe to weld each base pipe and to fix the reinforcing bars inserted into the base pipe. .

본 발명은 상술한 종래의 문제점을 해결하기 위하여 안출된 것으로서, 본 발명의 목적은 강관 상단에 씌워지는 덮개판 및 강관 내부로 위치되어 상기 덮개판을 지지시키는 보강판의 고정을 보다 용이하고도 안정되게 이루어지게 함과 동시에, 상기 덮개판상을 통해 용이한 배근이 이루어지도록 함으로써 효율적이며 하자발생의 염려를 최소화한 기초파일용 강관의 상단 배근구조를 제공하는 데 있다.The present invention has been made to solve the above-mentioned conventional problems, an object of the present invention is easier and more stable to fix the cover plate which is covered on the top of the steel pipe and the reinforcing plate which is located inside the steel pipe to support the cover plate. At the same time, it is to provide an upper reinforcement structure of the steel pipe for the foundation pile, which is efficient and minimizes the risk of defects by making the easy reinforcement through the cover plate.

상기 목적을 달성하기 위한 본 발명의 기초파일용 강관의 상단 배근구조는, 강관에의 보강판고정 및 보강판에의 덮개판고정이 각각 테이퍼핀의 사용에 의해 고정되고, 상기 덮개판에의 철근고정이 너트 또는 쐐기핀에 의해 고정되도록 한 것을 특징으로 한다.The upper reinforcement structure of the steel pipe for basic piles of the present invention for achieving the above object, the reinforcement plate fixed to the steel pipe and the cover plate fixing to the reinforcement plate is fixed by the use of tapered pin, respectively, the reinforcement to the cover plate It is characterized in that the fixing is fixed by a nut or wedge pin.
