Description
본 고안은 건축이나 토목의 기초공사에 있어서 지면에 타설한 강관의 상단부를 보강하기 위한 기초공사용 강관의 상단부 보강구조에 관한 것으로, 더 자세하게는 강관의 상단부에 다수의 끼움공을 마련한 원통캡형 강관보강부재를 설치하여 강관에 작용하는 수직하중 및 측토압에 의해 강관의 상단부가 변형되는 것을 방지할 수 있도록 함은 물론 확대기초콘크리트의 수직 연결철근을 간편하게 설치할 수 있도록 한 것에 관한 것이다.The present invention relates to the reinforcement structure of the upper end of the steel pipe for basic construction for reinforcing the upper end of the steel pipe placed on the ground in construction or civil engineering foundation, more specifically the cylindrical cap-type steel pipe reinforcement provided with a plurality of fitting holes in the upper end of the steel pipe By installing the member to prevent deformation of the upper end of the steel pipe by the vertical load and side soil pressure acting on the steel pipe, as well as to make it easy to install the vertical connecting reinforcement of the expanded foundation concrete.
일반적으로 건물이나 교량을 축조할 때에는 지면에 바이브로 해머 등으로 강관을 타설한 후 각 강관의 상부에 수직 연결철근을 설치하고 확대기초콘크리트를 타설하게 되는 바, 하단부가 지하의 암반에 지지되는 각 강관의 상단부에 작용하는 수직하중 및 강관의 외주면으로 작용하는 측토압에 의해 강관의 상단부가 변형되는 것을 방지하기 위해 강관의 상단부에 보강부재를 설치하는 것이 보통이다.In general, when building buildings or bridges, steel pipes are laid on the ground with vibrators, hammers, etc., and then vertical connecting bars are installed on the upper parts of each steel pipe, and expanded foundation concrete is placed. In order to prevent the upper end of the steel pipe from being deformed by the vertical load acting on the upper end of the steel pipe and the side earth pressure acting on the outer circumferential surface of the steel pipe, a reinforcing member is usually provided at the upper end of the steel pipe.
종래에 있어서 상기 강관의 상단부 보강구조는 강관의 내상단부에 수직 연결철근과 함께 콘크리트를 타설하는 것과 도 6 및 도 7과 같이 강관(10')의 내상단부에 십자형 보강부재(31')를 용접한 후 그 상부에 다시 지지원판(11')을 용접하고, 지지원판(11')의 상단 둘레에 다수의 수직 연결철근(21')을 용접하는 것, 그리고 지지원판을 용접한 십자형 보강부재를 체결볼트를 통해 강관에 고정 설치하고, 지지원판의 상단 둘레에 형성된 볼트체결공에 수직 연결철근을 나사 결합하는 것 등이 주로 사용되었다.Conventionally, the reinforcing structure of the upper end portion of the steel pipe is to cast concrete together with vertical connecting bars on the inner upper end of the steel pipe and to weld the cross-shaped reinforcing member 31 'to the inner upper end of the steel pipe 10' as shown in FIGS. 6 and 7. After that, the support disk 11 'is welded to the upper part again, the plurality of vertical connecting bars 21' are welded around the upper end of the support disk 11 ', and the cross reinforcement member welded to the support disk is It was mainly used to fix the steel pipes through fastening bolts, and to screw vertical connecting bars into bolt fastening holes formed around the top of the support disk.
상기 종래구조 중에서 우선 강관의 내상단부에 수직 연결철근과 함께 콘크리트를 타설하는 구조는 강관의 상단부를 견고하게 보강할 수 있기는 하지만 강관의 내부에 모래를 채워넣고 그 상부에 수직 연결철근과 함께 콘크리트를 부어넣은 후 굳혀야 하므로 시공성이 나쁘게 되는 문제가 있었고, 도 6 및 도 7과 같이 강관(10')의 내상부에 십자형 보강부재(31')를 용접하거나 체결볼트를 통해 고정 설치하고 십자형 보강부재(31')에 지지원판(11')과 수직 연결철근(21')을 용접하는 보강구조는 각 부재(31')(11')(21')을 강관(10')과 용접하는 과정에서 열변형에 의하여 강관(10')의 강도가 저하되고, 십자형 보강부재(31')에 접촉되지 않는 부위는 측토압이나 수직하중에 의해 변형될 우려가 많게 되는 문제가 있었을 뿐 아니라 많은 용접작업에 의해 수직 연결철근(21')을 설치하게 되므로 그 작업이 극히 번거롭게 되고 작업시간과 작업인력이 많이 소요되어 작업비용이 많이 들게 되는 문제가 있었다.Among the conventional structures, a structure in which concrete is poured together with vertical connecting bars at the inner upper end of the steel pipe can be firmly reinforced at the upper end of the steel pipe, but it is filled with sand in the inside of the steel pipe and concrete with vertical connecting bars at the top thereof. There was a problem that the workability is bad because it needs to be hardened after pouring, welded cross reinforcing member 31 'in the upper portion of the steel pipe (10') as shown in Figs. The reinforcing structure for welding the support disc 11 'and the vertical connecting bar 21' to the member 31 'is a process of welding each member 31', 11 ', 21' with the steel pipe 10 '. The strength of the steel pipe 10 'is reduced due to thermal deformation in the region, and the portion that is not in contact with the cross-shaped reinforcing member 31' has a problem that the deformation is caused by side pressure or vertical load. By vertical connecting bars (21 ') Since the installation is extremely cumbersome and the work time and work manpower takes a lot of work cost was a problem.
한편 지면에 타설되는 다수의 강관의 상부에는 바닥면 확대기초콘크리트공사를 위한 수평 바닥철근이 가로방향 및 세로방향으로 설치되는 바, 상기 종래의 강관 상단부 보강구조들에 있어서는 강관(10')의 상부에 수직 연결철근(21')을 먼저 설치하는 경우에 수직으로 세워진 수직 연결철근(21')이 강관(10') 주변에 수평 바닥철근을 설치하는 것을 방해하게 되어 작업이 힘들게 되는 문제가 있었고, 수평 바닥철근을 먼저 설치한 후에 수직 연결철근(21')을 용접하는 경우에도 강관(10') 주위에 설치된 수평 바닥철근이 수직 연결철근(21')의 설치작업을 방해하게 되는 문제가 있었다.On the other hand, in the upper part of the plurality of steel pipes which are poured on the ground, horizontal bottom rebars are installed in the horizontal direction and the vertical direction for the bottom-based foundation concrete construction. In the conventional reinforcing structure of the upper end of the steel pipe, the upper part of the steel pipe 10 ' In the case of installing the vertical connecting reinforcing bar (21 ') first in the vertical vertical connecting bar (21') standing vertically interferes with the installation of horizontal floor reinforcement around the steel pipe (10 ') there was a problem that the work is difficult, Even when the horizontal bottom reinforcing bar was first installed and the vertical connecting bar 21 'was welded, there was a problem that the horizontal bottom reinforcing bar installed around the steel pipe 10' interfered with the installation of the vertical connecting bar 21 '.
본 고안은 상기와 같은 종래의 실정을 감안하여 안출한 것이며, 그 목적이 지면에 타설되는 강관의 상단부를 보다 안정적으로 보강할 수 있도록 함은 물론 강관의 상단부에 보다 간편하게 수직 연결철근을 설치할 수 있도록 하는 기초공사용 강관의 상단부 보강구조를 제공하는 데에 있는 것이다.The present invention has been devised in view of the conventional situation as described above, and its purpose is to make it possible to more stably reinforce the upper end of the steel pipe to be placed on the ground, as well as to easily install a vertical connecting rebar on the upper end of the steel pipe It is to provide a reinforcement structure of the upper end of the foundation pipe.
