Abstract

The present invention relates to a head reinforcement structure for a tubular steel pile. More specifically, the present invention comprises a tubular steel pile whereof the top and bottom are open and a plurality of coupling holes are formed in the lower circumference. A circular reinforcement plate is inserted in the tubular steel pile and contains a plurality of holes on the edge thereof. One end of a fastening member is inserted in the hole formed in the circular reinforcement plate and is coupled therein with a nut and the other end is held in the upper circumference of the tubular steel pile to fasten the circular reinforcement plate to the lower inside of the tubular steel pile. A plurality of reinforcing members are formed and one side of each reinforcing member is beforehand welded with a bolt which is coupled with the coupling hole of the tubular steel pile. A cylindrical ring is coupled with the bolt before the bolt is coupled with the coupling hole of the tubular steel pile. A plurality of trapezoidal plates comprise insertion holes which are formed near the shortest sides thereof and a nut is welded near the insertion hole and the bottom thereof. According to the present invention, the bolt of the reinforcing member is first inserted into the cylindrical ring that has a certain length then is inserted facing outwardly into the coupling hole from the inside of the tubular steel pile. The end of the reinforcing member contacts the upper surface of the circular reinforcement plate. Thus, the reinforcing members are constantly distanced from the inner circumference of the tubular steel pile and the plate is placed on top of the reinforcing member then moves down until it is held on the upper circumference of the tubular steel pile. Furthermore, the shortest side of the plate faces the inside of the tubular steel pile, wherein the nut is coupled with the bolt then the tip of the bold contacts one side of the reinforcing member for anchoring the reinforcing member. In this way, the arrangement of lower base reinforcing rods is facilitated because a reinforcing member with a high-tension bolt is installed first then a linear reinforcing rod is installed after arranging the lower base reinforcing rods.

본 발명은 강관파일 두부보강 구조에 관한 것으로, 고장력볼트가 부착된 보강부재를 먼저 시공하고, 일자형 보강철근을 기초하부철근 배근 후에 시공되게 함으로써 기초하부철근 배근을 용이하게 하는 장점을 갖는 강관파일 두부보강 구조에 관한 것이다. The present invention relates to a steel pipe pile head reinforcement structure, the first construction of the reinforcing member is attached to the high-strength bolt, the steel pipe pile head having the advantage of facilitating reinforcement of the lower base reinforcement by the construction of a straight reinforcement reinforcement after foundation It relates to a reinforcement structure.
본 기술은 토목, 건축구조물의 하중을 비교적 깊고, 배토량이 작고, 견고한 지반에 확실히 전달하기 위해서 많이 사용되는 강관말뚝의 두부보강에 관한 것으로 현재 십자보강판볼트식(덮개판+볼트식) 머리보강공법, 합성식(볼트+속채움콘크리트) 두부보강공법, U자형보강철근이용 공법(U자형보강철근+속채움콘크리트)등의 신기술이 있으며 이들이 주로 많이 사용되고 있다. 그러나 이들 공법은 공통적으로 보강철근이 기초하부철근 보다 먼저 시공되어지는 관계로 기초하부철근 배근 시 방해가 된다. 또한 규격배근의 품질관리가 어렵고, 볼팅 체결을 100% 전부 검측 할 수 없는 상황이며, 한다고 해도 많은 시간이 소요될 수 밖에 없다. 확실한 검측이 이루어 질 수 없는 실정이다. 일부 공법은 볼팅 체결을 위한 캡의 두께가 두꺼울 수밖에 없어 무겁고, 자재비가 고가이다. This technology relates to the head reinforcement of steel pipe piles, which is widely used to ensure the load of civil engineering and building structures relatively deep, the amount of soil is applied to the ground firmly, and the cross reinforcement plate bolt type (cover plate + bolt type) There are new technologies such as construction method, synthetic formula (bolt + stuffed concrete), tofu reinforcement method and U-shaped reinforcement method (U-shaped reinforcing bar + stuffed concrete). However, these methods commonly interfere with the reinforcement of the base reinforcement because the rebar is constructed before the base reinforcement. In addition, it is difficult to control the quality of the standard bar, and 100% of the bolting tightening can not be detected, even if it takes a lot of time. Reliable detection is not possible. Some processes are heavy and expensive, because the cap for bolting is thick.
이들 공법은 일반적으로 508mm 강관말뚝두부보강 1본에 보강철근이 19mm 8가닥 들어가는데 최소 4-5가닥이 기초하부철근 배근에 방해를 준다. 강관말뚝이 여러 본 일 경우 그 방해는 더욱 심하다. 그러나 신기술이 아닌 말뚝두부보강 특허 중에 간섭제로인 공법들이 있지만 역학적인 측면과 자재, 시공, 품질관리 측면에서 꾸준히 연구되어져야할 과제이기도 하다. These methods generally include 1 reinforcement of 19mm reinforcement in one 508mm steel pipe pile head reinforcement, with at least 4-5 strands obstructing the lower base reinforcement. In case of multiple saws in steel pipe pile, the interference is more severe. However, although there are some methods of zero interference among pile tofu reinforcement patents that are not new technologies, it is also a problem that should be steadily studied in terms of mechanics, materials, construction, and quality control.
본 발명은 현행 도로교시방서에 준하여 속채움방식으로 하되 기초하부철근 배근 시 방해를 최소화하여 후속공정에 유리하고, 품질관리에 유리하며, 시공성이 있고, 경제성이 있으며, 구조 역학적으로 안정성이 있는 강관파일 두부보강 구조를 제공하는 데 있다. The present invention is in the filling method according to the current road bridge specifications, but minimizes the interference when reinforcement of the lower base reinforcement, which is advantageous for the subsequent process, quality control, construction, economical, structural dynamic stability steel pipe pile To provide a tofu reinforcement structure.
