본 고안은 소정의 크기로된 금속관체를 두겹의 납작한 금속판체를 압착한 다음 압착된 금속판체를 압형하여 두겹의 금속관체를 형성하고 금속관체의 접합부를 용접하여 속이 빈 관상의 철근을 형성하여서된 관상의 철근에 관한 것이다.The present invention is to form a two-layered metal tube by pressing a flat metal plate of a predetermined size and then press the pressed metal plate to form a double-layered metal tube and weld the joints of the metal tube to form a hollow tubular reinforcing bar It is about tubular rebar.
종래 각종 토목건축공사에 사용되는 철근은 속이 차여있는 철통으로 형성되어 있기 때문에 철근의 무개에 비하여 외력에 대응하는 힘이 부족하고 중량이 무거워 구조물의 하중을 크게하는 동시 철근값이 무개에 상응하게 높아 구조물의 시공미용이 높게 되는 등의 문제점이 있었다.Conventionally, the rebars used in various civil construction work are made of hollow cylinders. Therefore, compared to the rebar reinforcement, the rebar is weak and the weight is heavy. There were problems such as high construction beauty of the structure.
본 고안은 금속관체가 같은 크기의 금속봉에 비하여 외력에 대응하는 힘이 훨씬 강한 물리적인 작용을 이용하여 목적하는 철근의 굵기를 감안하여 미리 소정의 크기로 만든 금속관체를 압착하여 납작한 두겹의 금속판체로 형성하고 금속판체를 다시 압형하여 두겹의 외경이 보다 작은 금속관체를 형성한 다음 금속관체의 접합부를 용접하여 속이빈 관상의 철근을 형성함으로써 같은 굵기의 금속봉으로된 철근에 비하여 외력에 대응하는 힘이 훨씬 향상되는 동시 질량이 보다 가볍고 따라서 관상철근값이 보다 경제적으로 저렵하게 될 뿐만 아니라 철근을 상요한 구조물의 하중을 보다 가볍게 줄일 수 있어 그로인한 여러 가지 물리적인 이점을 얻을 수 있는등 보다 편리하게 사용할 수 있게 안출한 것으로 이를 도면에 의하여 상세히 설명하면 다음과 같다.The present invention forms a flat two-layered metal plate by pressing a metal tube made of a predetermined size in consideration of the desired thickness of the reinforcing bar by using a physical effect in which the metal tube has a stronger force corresponding to external force than a metal rod of the same size. The metal plate body is again pressed to form a metal tube with a smaller outer diameter and then welded to the joint of the metal tube to form hollow tubular reinforcing bars, so that the force corresponding to external force is much higher than that of steel bars of the same thickness. The improved simultaneous mass is lighter, and thus the coronal reinforcement value is more economically cheaper, and the load of the reinforcing steel-reinforced structure can be lighter, resulting in various physical benefits. If it is described in detail by the drawings as follows. The.
목적하는 철근의 외경의 대략 2배의 외경으로 형성된 금속관체(1)를 압착하여 감속관체의 주면끼리 압착된 두겹의 금속판체(2)를 형성하고 이 금속판체(2)를 압형하여 속이 빈 두겹의 금속관체(3)를 형성한 다음 금속관체(3)의 접합부(4)를 용접하여 두겹으로된 속이빈 관상의 철근(5)을 형성하여서 된 것이다.Pressing the metal tube 1 formed with an outer diameter approximately twice as large as the outer diameter of the desired reinforcing bar to form a double-layered metal plate body 2 pressed between the main surfaces of the reduction pipe body, and pressing the metal plate body 2 to the hollow double layer After forming the metal tube (3) of the metal tube (3) by joining the joint (4) of the hollow tubular reinforcing bar (5) of two layers is formed.
도면중 미설명 부호 6은 압형시에 형성된 보강돌조이다.In the figure, reference numeral 6 is a reinforcing protrusion formed at the time of pressing.
이와 같이된 본 고안은 각종 토목건축공사나 기타 철근공사 또는 철 구조물등에 사용하는 것으로 임의 크기로된 금속간체(1)를 압형하여 두겹의 납작한 금속판체(2)를 형성하고 이 금속판체(2)를 다시 압형하여 두겹의 외경이 보다 작은 금속관체(3)를 형성하여 접합부(4)를 용접하여서 관상의 철근을 형성하였기 때문에 금속관체(1)의 반복적인 압형과정에서 조직이 보다 조밀하게 형성된 철근(5)의 내외 두겹의 금속관체(3)에 의하여 외력에 대응하는 힘이 훨씬 향상되는 동시 종래 일반금속봉으로 된 철근에 비하여 질량이 보다 가볍고 가벼운만큼 철근값이 경제적으로 저렴하게되어 각종 토목건축공사에 보다 경제적으로 유용하게 사용할 수 있는 동시 구조물의 무게를 보다 가볍게 줄일 수 있는 등 각종 용도에 보다 편리하게 사용할 수 있는 효과가 있다.The present invention as described above is used for various civil construction works or other reinforcement works or steel structures, etc., to form a flat metal plate body 2 of two layers by pressing an intermetallic body 1 having an arbitrary size, and the metal plate body 2 By pressing again to form a metal tube (3) having a smaller outer diameter of two layers to weld the joint (4) to form a tubular reinforcement, because the repetitive pressing process of the metal tube (1) the tissue is formed more densely At the same time, the force corresponding to external force is much improved by the inner and outer double-layered metal pipes (3). As the mass is lighter and lighter than the conventional steel bars, the rebar value is economically inexpensive. It can be used more conveniently for various purposes, such as to reduce the weight of simultaneous structures that can be used more economically and lighter. .
