본 발명은 건축이나 토목의 기초공사에 있어서 지면으로부터 타입한 강관(100)말뚝의 머리를 보강하여 모든 외력에 대해 저항할 수 있도록 하기 위한 기초 공사용 강관의 상단부 보강구조에 관한 것으로 특히 지면으로부터 타입 된 강관(100)의 상단부에 원형링(55)과 원판(30)을 달대(10)로 연결한 부재를 설치하되 원판(30)의 직경은 강관(100)말뚝의 내경보다 적게 하여 강관(100)의 내 상단에 삽입되도록 하고 원형링(55)의 외경은 강관(100)말뚝의 외경보다 크게하여 강관(100)말뚝위에 걸쳐지도록 한 후 전단키(20)를 설치하고 확대기초의 하부철근(3)조립 후 확대기초의 하부철근(3)의 윗면 강관(100)말뚝 수직위치에 띠철근(450) 1개를 먼저 고정하고 띠철근(450)의 안쪽으로 보강철근(400)을 설치하되 확대기초 하부철근(3)의 간섭을 피해 설치하여 확대기초 콘크리트(500)타설시 본 발명의 부재설치로 인해 마련된 공간에 콘크리트가 유입되도록 한 기초공사용 강관의상단부 보강구조에 관한 것으로 원형링(55)은 확대기초콘크리트(500)의 수직지압응력집중을 완화시키는 기능을 담당하고 또 원형링(55)에 홀이나 홈을 형성하지 않음으로 보강철근이 원형링(55)에 구속되어 확대기초 하부철근(3)의 간섭받는 일이 없도록 했다. 전단키(20)는 인발하중에 저항하는 기능을 하며 확대기초 하부철근(3)의 윗부분 강관(100)과 수직된 위치에 고정된 1개의 띠철근(450)은 보강철근(400)을 결속하여 안정시키는 기능을 한다. 보강철근(400) 이 말굽형태와 양단에 갈고리모양을 갖추어 보강철근 2개를 한번에 정착하는 효과와 함께 부착력을 증대시켜 자재의 절감효과를 제공하고 확대기초콘크리트(500) 타설시 강관(100)내부로 유입되는 속채움 콘크리트(5)에 의하여 강관(100)과 확대기초콘크리트(500)가 강결합(일체화) 되도록 한 기초공사용 강관의 상단부 보강구조에 관한 것이다.The present invention relates to the reinforcing structure of the upper end portion of the steel pipe for the foundation construction for reinforcing the head of the steel pipe (100) pile type from the ground in the construction or civil engineering foundation so that it can resist against all external forces. Install a member connecting the circular ring 55 and the disc 30 to the moon 10 at the upper end of the steel pipe 100, but the diameter of the disc 30 is less than the inner diameter of the steel pipe 100, the steel pipe 100 The outer diameter of the circular ring 55 is to be inserted into the upper end of the larger than the outer diameter of the steel pipe (100) pile so as to span over the steel pipe (100) pile, then install the shear key 20 and the lower reinforcement of the expansion base (3) After assembly, fix one strip reinforcing rod 450 first at the vertical position of the upper steel pipe 100 of the lower reinforcing bar 3 of the expanding base, and install the reinforcing bar 400 inside the reinforcing bar 450, but Expanded foundation concrete by installing to avoid interference of rebar (3) (500) relates to the reinforcement structure of the upper end of the steel pipe for the basic construction to allow concrete to flow into the space provided by the installation of the member at the time of placing the circular ring 55 to reduce the vertical pressure stress concentration of the expanded basic concrete (500) In addition, the reinforcing bars were constrained to the circular ring 55 by not functioning and forming holes or grooves in the circular ring 55 so as not to be interfered with by the expansion base lower reinforcing bar 3. Shear key 20 functions to resist the draw load, and one strip of steel 450 fixed at a position perpendicular to the upper steel pipe 100 of the expanded base lower rebar 3 is stabilized by binding the reinforcing bar 400. To function. The reinforcing bar (400) has a horseshoe shape and a hook shape at both ends to provide the effect of fixing two reinforcing bars at once and increase the adhesive force to provide material saving effect and to expand the basic concrete (500). It relates to the reinforcing structure of the upper end of the steel pipe 100 and the basic public steel pipe to be a steel coupling (100) and the expanded basic concrete (500) by the inner filling concrete (5).

종래에는 지면으로부터 타입 된 강관(100)말뚝머리가 모든 외력에 안전하게 저항하도록 용접이나 볼트조립 방법 또는 여러 부재를 사용하여 콘크리트를 강관(100) 내 상단에 유입되도록 한 방법을 통하여 강관(100)상단부를 보강하는 것이 일반적 이었다. 그러나 종래의 방법들은 품질관리가 어렵고 시공이 불편할뿐더러 보강철근(400)의 설치 위치가 고정됨으로 확대기초 하부철근(3)과 보강철근(400)의 간섭을 완전히 피하지 못해 규격시공이 어려운 문제가 있었다.Conventionally, the upper end of the steel pipe (100) through the method to allow the concrete to flow into the upper end of the steel pipe (100) using a welding or bolt assembly method or several members to safely resist the type of steel pipe 100 from the ground It was common to reinforce it. However, the conventional methods are difficult to control quality and inconvenient in construction, and because the installation location of the reinforcing bar 400 is fixed, it is difficult to completely avoid the interference between the base reinforcing bar 3 and the reinforcing bar 400. there was.

따라서, 본 발명의 목적은 종래와 같은 용접이나 볼트 조임을 하지 않고 안정적으로 강관(100)의 상단부를 보강하여 모든 외력에 저항케 함은 물론 보강철근(400)의 설치 위치를 고정시키지 않고 유동성을 확보하므로 확대기초 하부철근(3)의 간섭을 피해 보강철근(400)의 시공을 용의하게 하는 기초공사용 강관의 상단부 보강구조를 제공하려는데 있는 것이다.Accordingly, an object of the present invention is to stably reinforce the upper end of the steel pipe 100 without welding or bolting as in the prior art to resist any external force, as well as to maintain the fluidity without fixing the installation position of the reinforcing bar 400 It is to provide a reinforcement structure of the upper end portion of the steel pipe for the basic construction to facilitate the construction of the reinforcement reinforcement (400) to avoid the interference of the expansion base lower reinforcement (3).

이하 첨부된 도면에 의거하여 본 발명의 바람직한 일실시예를 설명하면 다음과 같다. 참고로 이하에 참조되는 도면에 대하여는 설명의 편의상 종래와 동일한 부분에 대해서는 동일한 참조 번호를 부여하여 설명한다.Hereinafter, a preferred embodiment of the present invention will be described with reference to the accompanying drawings. For reference, the drawings referred to below will be described with the same reference numerals for the same parts as in the prior art for convenience of description.

본 발명은 원형링(55)과 원판(30)을 달대(10)로 연결한 부재를 강관(100)말 뚝의 상단에 설치하되 원판(30)의 직경은 강관(100)말뚝의 내경보다 적게 하여 강관(100)의 내 상단에 삽입되도록 하고 원형링(55)의 외경은 강관(100)말뚝의 외경보다 크게 하고 강관(100)말뚝위에 걸쳐지도록 하여 강관(100)상단에 일정공간을 확보한 다음 콘크리트가 유입되도록 하고 원형링(55)은 축력작용 시 확대기초콘크리트(500)의 수직 지압응력집중을 완화하는 기능을 담당케 되며 강관(100)에 타공된 전단키설치구멍(22)을 통해 외주면 으로부터 강관(100)내부로 설치되는 전단키(20)는 축력의 일부와 인발에 대한 저항을 하도록 했으며, 본 발명은 확대기초 하부철근(3)조립 후 띠철근(450)1개를 확대기초 하부철근(3)윗면 강관(100)과 수직위치에 고정결속하고 띠철근(450) 안쪽에 수직으로 보강철근(400)을 세워 이미 고정된 띠철근(450)에 결속한다.The present invention is installed on the upper end of the steel pipe 100 pile the member connecting the circular ring 55 and the disk 30 to the moon 10, the diameter of the disk 30 is less than the inner diameter of the steel pipe 100 pile The outer diameter of the circular ring 55 is made larger than the outer diameter of the steel pipe 100 pile and is spread over the steel pipe 100 pile so as to secure a predetermined space at the top of the steel pipe 100. Next, the concrete is introduced and the circular ring 55 is responsible for alleviating the vertical pressure stress concentration of the expanded basic concrete 500 during the axial force, and the outer peripheral surface through the shear key installation hole 22 perforated in the steel pipe 100. Shear key 20 installed from the inside of the steel pipe 100 to the resistance to the part of the axial force and the draw, the present invention after the expansion base bottom reinforcement (3) assembled one band reinforcement (450) to expand the base bottom reinforcement (3) fixedly fixed in the vertical position with the upper steel pipe (100) and vertically inside the band reinforcement (450) Stand up reinforcement (400) is bound to the already fixed band reinforcement (450).

강관(100)말뚝머리에 외력이 작용할 때 보강철근(400)이 이탈하지 못하도록 하는 기능은 강관(100)이 속채움 콘크리트(5)를 구속하는 원리를 이용하여 강관(100)내부에 위치하는 보강철근(400)에는 띠철근(450)을 설치하지 않도록 하여 시공성과 경제성을 높였다.Reinforcing reinforcement 400 is a function to prevent the reinforcing reinforcement 400 when the external force is applied to the steel pipe 100 pile head reinforcement located inside the steel pipe 100 by using the principle of restraining the filling concrete (5) The reinforcing bar 400 was not provided with a band reinforcing bar 450 to improve construction and economics.

이상에서 설명한바 와같이 본 발명은 강관(100)의 내상단부에 원형링(55)과 원판(30)을 달대(10)로 연결한 부재를 용접이나 볼트 조임 없이 강관(100) 상단에 설치하여 효과적으로 강관(100)말뚝머리 보강을 하고 원형링(55)이 보강철근(400)을 구속하지 않음으로 보강철근(400)과 확대기초 하부철근(3)의 간섭 없이 규격시공이 기능한 효과를 제공한다.As described above, the present invention is installed on the upper end of the steel pipe 100 without welding or bolting the member connecting the circular ring 55 and the disc 30 to the moon 10 at the inner upper end of the steel pipe 100 Effectively reinforcing the steel pipe 100 pile head and circular ring 55 does not restrain the reinforcing bar 400, thereby providing the effect that the standard construction function without interference between the reinforcing bar 400 and the lower base reinforcement (3) do.

본 발명은 상술한 특정의 바람직한 실시예의 한정되지 아니하며 청구범위에서 청구하는 본 발명의 요지를 벗어남이 없이 당해 발명이 속하는 기술분야에서 통상의 지식을 가진 자라면 누구든지 변형실시가 가능한 것을 물론이고 그와 같은 변경은 청구범위 기재의 범위 내에 있게 된다.The present invention is not limited to the specific preferred embodiments described above, and any person having ordinary skill in the art to which the present invention pertains may make modifications without departing from the gist of the present invention as claimed in the claims.
