Abstract

PURPOSE: A structure of an iron pipe is provided to make a material for a frame have stronger resistant stress than an iron pipe having the same circumference by enlarging the section area and the secondary moment of the section of a pipe by fixing an iron reinforcement rib of proper size and shape. CONSTITUTION: A structure is formed by gaining the thickness and shape of a reinforcement rib via structure analysis when an iron pipe for a frame embedding the reinforcement rib is needed, preparing a reinforcement rib(2) to be applied for the design and inserting the reinforcement rib to a pipe(1) by using consolidation. The reinforcement rib is fixed by using welding, a bolt and a fixing metal tool. Herein, the secondary moment of the section of the iron pipe is increased so that the stress resisting to its weight and the exterior force becomes stronger. Therefore, the pipe receives stronger stress than usual pipes of the same circumference and thickness as the iron pipe embedding a reinforcement rib.

Description

보강리브가 내설된 구조용 철재관의 구조{.}Structural Steel Pipe Structure with Reinforcement Ribs {.}

본 발명은 시설물의 구조용재로 널리 사용되고 있는 재질이 강(STEEL) 및 스텐레스 등으로 된 철재관의 구조에 관한 것으로, 관이 보다 큰 자중과 외력에 견딜 수 있도록 한 것이다.The present invention relates to the structure of steel pipes made of steel (STEEL), stainless steel, and the like, which are widely used as structural materials of facilities, to allow the tubes to withstand greater weight and external forces.

일반적으로 구조재로 쓰이는 부재의 경우 단면형상에 따라 자중 및 외력에 저항하는 힘의 크기가 결정된다. 즉 축력과 전단력은 부재의 단면적이, 모멘트는 단면2차 모멘트가 그 주요 인자 이다.In general, in the case of a member used as a structural member, the cross section shape determines the magnitude of the force that resists its own weight and external force. In other words, the axial and shear forces are the cross-sectional area of the member, and the moment is the cross-sectional secondary moment.

구조재로 사용되는 철재관의 경우 외경과 두께가 표준화되어 생산되기 때문에 종래에는 부재가 받을 수 있는 응력이 부족할 경우 같은 외경에서 두께가 두꺼운 관을, 그래도 부족할 경우 외경이 큰 관을 선택해왔다.In the case of steel pipes used as structural materials, since the outer diameter and thickness are standardized and produced, conventionally, when the stress that a member lacks is insufficient, a thick tube at the same outer diameter is still selected, and a tube having a large outer diameter is still selected.

그러나 외경이 큰 관을 선택하는 데는 투박하여 외관상의 문제점, 연결되는 다른 부재도 치수가 달라져야 하는 문제점, 연결 구조물과의 문제점이 있을 뿐만 아니라 경제적인 측면에서도 문제점이 있는 실정이다.However, there is a problem in selecting a tube having a large outer diameter due to its problem in appearance, problems in that the other members to be connected must have different dimensions, problems with the connecting structure, as well as economical aspects.

이와 같은 종래의 구조용 철재관의 문제점을 보완하고자 본 발명은 정해진 치수로 생산되고 있는 철재관에 단면적과 단면2차 모멘트를 크게하여 구조용재의 저항응력을 높여 보겠다는 것이다. 즉, 구조용 철재관 내부 공간에 구조계산을 통하여 구해진 적절한 치수와 모양의 철재 보강리브를 내설 고정시킴으로 관의 단면적과 단면2차 모멘트를 크게하여 구조용재가 동일 외경의 철재관보다 더 큰 저항응력을 가질 수 있도록 하는데 그 목적이 있다.In order to supplement the problems of the conventional structural steel pipes, the present invention intends to increase the resistance stress of structural materials by increasing the cross-sectional area and the cross-sectional secondary moment in the steel pipes produced with the predetermined dimensions. In other words, by internally fixing steel reinforcement ribs of appropriate dimensions and shapes obtained through structural calculations in the internal space of structural steel pipes, the cross-sectional area and cross-sectional secondary moment of the pipes are increased so that the structural material has greater resistance stress than steel pipes of the same outer diameter Its purpose is to have it.

1: 구조용 철재관 2: 철재 보강리브1: structural steel pipe 2: steel reinforcement rib

이러한 목적을 달성하기 위한 본 발명의 기술적 구성을 살펴보기로 한다.To look at the technical configuration of the present invention for achieving this object.

원형 및 각형상의 구조용 철재관 내부 공간에 "｜" 자형, "＋" 자형 등 다양한 모양의 철재 보강리브를 내설 고정 시키는 것을 특징으로 하고 있다.Steel reinforcing ribs of various shapes such as "|" shape and "+" shape are internally fixed to the inner space of the structural steel pipe of round and square shape.

본 발명의 실시 예를 첨부한 도면을 참고하여 설명하면 다음과 같다.An embodiment of the present invention will be described with reference to the accompanying drawings.

본 발명의 보강리브가 내설된 구조용 철재관을 필요 할 때 먼저 구조해석을 통하여 보강리브의 두께, 형상 등을 구한다음, 설계에 맞게 보강리브를 제작하여 압밀 등의 방법을 통하여 관(도1의 1) 내경에 집어넣는다.(도1의 2)When reinforcing ribs of the present invention require a structural steel pipe with a built-in reinforcing rib, first obtain the thickness, shape, and the like of the reinforcing ribs through structural analysis. ) Into the inner diameter (2 in Fig. 1).

관과 내설 된 보강리브는 용접, 볼트, 고정금구 등을 이용하여 고정하도록 한다.Pipes and internal reinforcement ribs should be fixed by welding, bolts, and fixing brackets.

또한 본 발명의 보강리브가 내설된 구조용 철재관은 표준화된 치수와 형상으로 공장에서 생산하여 필요한 규격을 이용할 수도 있다.In addition, the structural steel pipe in which the reinforcing rib of the present invention is built may be used at a factory to produce a standardized dimension and shape.

도2에서 도7까지는 원형 및 각 형상의 구조용 철재관에서 "｜"형, "＋"형, ""형 등 여러 모양의 보강리브를 내설한 관의 단면도들이다.2 to 7, "|" type, "+" type, " Cross-sectional views of pipes with reinforcement ribs of various shapes, such as "type."

상기와 같은 본 발명에 의하면 시설물의 구조용재로 쓰이는 원형 및 각형상의 철재관에 있어서 관 내부에 철재 보강리브를 내설시킴으로써 단면2차 모멘트가 크게 되어 구조용재가 자중과 외력에 저항할 수 있는 응력을 증대시킨다. 따라서 동일 외경과 두께의 일반관보다 더 많은 응력을 받을 수 있게 되며, 종래의 더 큰 외경을 선택해야하는 불합리한 점을 해소할 수 있을 뿐만 아니라 경제성과 구조적 안정성 관점에서도 유용한 발명인 것이다.According to the present invention as described above in the round and square steel pipes used as structural materials of the facility by the steel reinforcing ribs in the inside of the pipe by increasing the second moment of the cross-section to increase the stress that the structural material can resist its own weight and external force Increase Therefore, it is possible to receive more stress than a general tube of the same outer diameter and thickness, and to solve the unreasonable point of selecting a larger outer diameter of the prior art as well as a useful invention in terms of economics and structural stability.
