Description

강관말뚝 두부보강 장치{The head reinforce equipment of a steel pipe pile}Head reinforce equipment of a steel pipe pile}

본 고안은 토목 또는 건축 구조물의 기초로 사용되는 강관말뚝에 관한 것으로서, 보다 상세하게는 강관말뚝의 두부와 콘크리트 기초를 결합하는 강관말뚝 결합부분에 관한 것이다.The present invention relates to a steel pipe pile used as a foundation of civil engineering or building structures, and more particularly, to a steel pipe pile coupling portion for coupling the head and concrete foundation of the steel pipe pile.

국내의 도로교 표준시방서(1999)에는 강관말뚝의 머리부와 콘크리트 기초를 결합하는 방법에 대하여 다음과 같은 2가지 방법을 규정하고 있다.In Korea, the standard specification for road bridges (1999) stipulates the following two methods for joining the steel pipe pile head and concrete foundation.

즉, 콘크리트 기초내에 강관말뚝의 두부를 강관말뚝의 직경 이상의 길이로 묻고 그 묻힌 부분으로 강관말뚝의 두부에 작용하는 외력을 지지하는 방법(A방법)과, 콘크리트 기초내에 강관말뚝의 두부를 10cm정도의 길이만 묻고 부족한 내력은 보강철근으로 보강하여 강관말뚝의 두부에 작용하는 외력을 지지하는 방법(B방법)이 있다.In other words, buried the head of the steel pipe pile in the concrete foundation with a length greater than the diameter of the steel pipe pile and supporting the external force acting on the head of the steel pipe pile with the buried portion (A method), and the head of the steel pipe pile in the concrete foundation is about 10cm There is a method of supporting the external force acting on the head of the steel pipe pile by reinforcing the lacking strength by reinforcing steel bars.

상기 A방법은 콘크리트 기초내에 묻힌 강관말뚝의 간섭으로 콘크리트 기초의 저면에 배근되는 주철근이 절단되어 B방법보다 철근 배근이 복잡하고 철근량이 더 소요된다는 단점이 있다. 따라서, 일반적으로 B방법이 주로 이용되고 있다.The method A has a disadvantage in that the reinforcing reinforcement is more complicated and the reinforcing reinforcement is required than the method B because the main reinforcing bars are cut at the bottom of the concrete foundation due to the interference of the steel pipe pile embedded in the concrete foundation. Therefore, in general, the B method is mainly used.

국내의 도로교 표준시방서에 제시된 상기 2가지 방법 모두 일본 도로교 표준시방서의 규정에 따른 것인데 1980년도의 일본의 도로교 시방서에 제시된 B방법은 강관말뚝 내에 +자 보강판을 삽입하여 용접한후, 원형 덥개판을 강관말뚝의 머리부에 씌워 용접한 다음, 강관말뚝 측면에 보강철근을 용접하는 방법이며, 아래와 같은 문제점들이 있다.Both of the above methods presented in the standard road bridge specifications of Korea are in accordance with the standards of the standard road bridge standards in Japan.The method B proposed in the road bridge specifications in Japan in 1980 is a round cover plate after welding by inserting a + -shaped reinforcement plate into the steel pipe pile. To cover the head of the steel pipe pile, and then weld the reinforcing steel to the steel pipe pile side, there are the following problems.

① 강관말뚝 두부에 덮개판을 씌우는 본래 목적이 지압면적을 크게 해서 압입력에 대한 분산효과를 높이고, 압입력에 의해 강관말뚝에 발생하는 응력의 집중을 줄이고자 한 것이나, 실험결과 그 효과가 없었으며, 오히려 덮개판을 씌우지 않고 강관말뚝 두부 내부를 콘크리트로 속채움하는 구조가 더 효과적이었다.① The original purpose of the cover plate on the steel pipe pile was to increase the pressure area to increase the dispersion effect on the pressure input, and to reduce the concentration of stress generated on the steel pipe pile by the pressure input. Rather, it was more effective to fill the inside of the steel pipe pile head with concrete without covering the cover plate.

② 콘크리트 기초와 강관말뚝의 결합부는 단면적이 급변하여 구조적으로 취약하므로 강관말뚝 내부를 +자 보강판으로 보강하였으나, +자 보강판의 무게가 무거워 시공성 및 경제성이 불량하다.② The joint part of the concrete foundation and the steel pipe pile is structurally weak due to the sudden change in the cross-sectional area, so the steel pipe pile is reinforced with a + -shaped reinforcement plate. However, the weight of the + -shaped reinforcement plate is heavy, resulting in poor construction and economic efficiency.

③ 강판말뚝 측면에 보강철근을 용접하는 작업이 힘들다.③ It is hard to weld reinforcing bar on the side of steel plate.

한편 상기 문제점들 중에서 용접 작업의 어려움을 해결한 것으로 특허 제10-02239166호가 개발되었으나, 강관말뚝에 작용하는 압입력을 강관말뚝의 상부에 씌워지는 +자형 보강판을 부착한 덮개판을 이용하여 지지하기 때문에 여전히 ①및 ②의 문제점을 안고 있다.On the other hand, Patent No. 10-02239166 was developed to solve the difficulty of welding work, but the pressing force acting on the steel pipe pile is supported by using a cover plate with a + -shaped reinforcement plate which is covered on the top of the steel pipe pile. It still has the problems of ① and ②.

강관말뚝 내부를 콘크리트로 속채움하는 B방법을 도1에 도시하였다. 상기 방법은 강관말뚝 내에 2열의 미끄럼 방지턱과 합판 걸림턱을 용접한후, 보강철근을 삽입하고 콘크리트를 타설함으로써 콘크리트 기초에 작용하는 외력을 지탱하는 구조이다.A method of filling a steel pipe pile with concrete is shown in FIG. 1. The method is a structure that supports the external force acting on the concrete foundation by welding two rows of anti-skid jaws and plywood engaging jaws in the steel pipe pile, inserting reinforcing bars and pouring concrete.

그러나 상기 방법은 좁은 공간의 강관말뚝 내부에 미끄럼 방지턱과 합판 걸림턱을 용접해야 하므로 용접작업 자체가 힘드록, 용접불량이 발생하기 쉬우며, 보강철근을 강관말뚝 내부에 삽입하고 속채움 콘크리트로 고정시킨 상태에서 콘크리트 기초 철근을 배치하고 조립해야 하므로 보강철근이 콘크리트 기초의 철근 배치 및 조립에 간섭하게 되어 시공성이 불량하다는 점과 그 단가 역시 고가가 되는 문제점을 안고 있다.However, the above method requires welding the non-slip jaw and the plywood hooking jaw inside the narrow pipe pile in a narrow space, so that the welding work itself is difficult, and it is easy to cause welding defects. The reinforcing bars are inserted into the steel pipe pile and fixed with stuffed concrete. Since it is necessary to arrange and assemble the concrete foundation reinforcing bars in the state, the reinforcing bars interfere with the arrangement and assembly of the reinforcing bars of the concrete foundation, resulting in poor workability and cost.

도1과 같은 종래의 방법을 개선하기 위하여 고안된 종래기술인 도2는 지중에 향타된 강관말뚝(2), 상기 강관말뚝(2)의 두부 직경보다약간 작은 직경의 원판으로써 상기 강관말뚝의 두부속으로 삽입되어 고정되며, 상부면 바깥쪽에는 방사상으로 다수개의 암나사구멍이 형성된 결합구(8), 상기 결합구(8)를 상기 강관말뚝(2)의 두부 내부에 고정시키는 볼트, 단부에 수나사가 형성되어 상기 결합구(8)의 상부면에 형성된 암나사구멍에 체결되는 다수개의 보강철근(3)및 상기 강관말뚝(2)의 두부를 포함하며 상기 강관말뚝(2)위로 형성되는 콘크리트 기초(1)로 구성된다.2, which is a conventional technology designed to improve the conventional method as shown in FIG. 1, is a disc of slightly smaller diameter than the head diameter of the steel pipe pile 2 and the steel pipe pile 2, which is directed to the inside of the steel pipe pile. Inserted and fixed, the coupling hole 8 is formed with a plurality of female threaded holes radially outside the upper surface, bolts for fixing the coupling hole 8 in the head of the steel pipe pile 2, the male thread is formed at the end A concrete foundation (1) formed over the steel pipe pile (2) and including a plurality of reinforcing bars (3) and heads of the steel pipe piles (2) fastened to female threaded holes formed on the upper surface of the coupling hole (8). It consists of.

도2의 종래발명은 강관말뚝 두부에 작용하는 축방향력을 강관말뚝 표면과 콘크리트 사이에서 발휘되는 부착력 성분과 강관말뚝과 결합구를 고정시키는 볼트의 내력성분으로 견뎌야 한다.The conventional invention of Figure 2 has to endure the axial force acting on the steel pipe pile head with the component of the adhesion force exerted between the steel pipe pile surface and the concrete and the strength component of the bolt fixing the steel pipe pile and the coupling.

그러므로 볼트의 내력으로 압입력을 견디기 위해 필요한 볼트가 일정 수량이 필요하게 되며, 부착력을 어느 정도 확보하려면 결합구의 위치가 강관의 직경보다 아래에 있어야 하므로 결합구와 강관을 체결하는데 필요한 볼트공의 위치가 지표면보다 밑에 있게 되어 강관에 볼트구멍을 천공하기가 힘든 문제점이 있다.Therefore, a certain number of bolts are required to withstand the pressure input with the bolt's internal force.To secure the attachment force, the position of the bolt hole required to join the coupler with the steel pipe is necessary because the position of the coupler must be below the diameter of the steel pipe. There is a problem that it is difficult to drill the bolt holes in the steel pipe because it is below the ground.

또 현장에서 볼트와 너트를 이용한 조립을 하기에 앞서 상기 강관말뚝 머리부와 콘크리트 기초의 결합을 위한 결합구 및 이를 이용한 결합구조의 생산이 주물형성을 통해 이루어져야 한다는 점에서 비용이 고가가 되고, 현장에서 강관 말뚝두부와 콘크리트에 연결되어진 철근과 맞대어 시공되는 바닥철근을 시공하는데 있어 바닥철근의 곧은 설치를 위해 상기 강관 말뚝용 덮개판에 체결되어진 철근을 움직이는 경우에 상기 철근의 하단부가 덮개판에 볼트와 너트로 완전고정이 되어있기 때문에 철근의 부러짐이 일어나는 경우가 많다.In addition, before assembling with bolts and nuts in the field, cost is expensive because the production of the coupling tool for coupling the steel pipe pile head and the concrete foundation and the coupling structure using the same must be achieved through casting. In the construction of the bottom reinforcing bar to be constructed against the steel pipe pile head and the reinforcing bar connected to the concrete in the case of moving the reinforcing bar fastened to the cover plate for the steel pipe pile for the straight installation of the bottom reinforcement bolts on the cover The steel bars are broken completely because they are completely fixed with nuts and nuts.

이에 본 고안은 이상과 같은 문제점을 해결하기 위하여 창안된 것으로, 본 고안의 목적은 강관의 두부보강을 철근 구조물과 콘크리트의 조화로 지지 강도의 우수성은 물론 재료비를 절감하고 현장에서 간단히 시공할 수 있으며 현장에서 바닥철근을 시공하는데 있어서도 강관말뚝에 결합되는 철근을 강관말뚝 두부보강 장치에 달리 결합을 할 수 있어 바닥철근의 곧은 설치가 유용하도록 그 목적을 가지는 것이다.Therefore, the present invention was devised to solve the above problems, and the purpose of the present invention is to combine the reinforcing head of steel pipe with the reinforcing steel structure and concrete, which can reduce the cost of materials as well as the excellent support strength and can be easily installed on site. In the construction of floor reinforcement in the field can be combined with the steel pipe pile head reinforcing device can be combined with the steel pipe pile is to have the purpose of the straight installation of floor reinforcement useful.

As shown in FIG. 2, the steel pipe pile 100 and the reinforcing steel 20 in the prior art (Registration No. 10-0229166) are joined to the steel pipe pile as compared with the bolts and nuts formed on the cover plate 10. The part 20 does not constitute a cover plate so that the whole is already manufactured and provided to the site. The combination of the reinforcing bar 23 and the steel pipe 21 having a shape is made.

상기 강관내부 고정장치(1)는 강관내부에 삽입되어 강관내부를 막는 종래의 거푸집의 역할을 하는 강관막음원판(11)과 강관걸림철근(12)으로 구성되어 있다.The steel pipe inner fixing device (1) is composed of a steel pipe blocking source plate 11 and a steel pipe locking reinforcement (12) which serves as a conventional formwork to be inserted into the steel pipe to block the inside of the steel pipe.
