본 발명은 하중을 지지하는 구조물의 골조에 사용되는 트러스에 관한 것이며, 특히, 상하현재 및 웨브재가 일체로 성형된 단위부재를 사용하여 구성한 트러스에 관한 것이다.TECHNICAL FIELD The present invention relates to a truss used for a frame of a structure supporting a load, and more particularly, to a truss configured by using a unit member in which the upper and lower chords and the web material are integrally formed.

도 1은 종래기술에 따른 구조물의 골조로 사용되는 트러스를 나타낸 도면이다.1 is a view showing the truss used as the framework of the structure according to the prior art.

도 1에 도시된 바와 같이, 트러스(10)는 구조물의 지붕골조 또는 바닥골조에 사용되는 구조부재로서, 이런 구조부재는 다양한 삼각형, 원형 등의 모양으로 제작될 수 있다.As shown in Figure 1, the truss 10 is a structural member used in the roof frame or floor frame of the structure, such a structural member can be produced in a variety of triangles, circles and the like.

일반적으로 제작되는 트러스(10)는 상현재(11), 하현재(12) 및, 그 사이에 연결되는 웨브재(13)로 구성되며, 나사, 클린칭, 용접 등의 방법에 의해 각각의 부재가 상호 고정된다. 이러한 트러스(10)는 설치되는 구조물의 위치에 따라 다양한 모양으로 제작될 수 있는데, 바닥골조에는 평트러스가 주로 설치되고, 지붕골조에는 지붕의 형상에 따라 다양한 트러스가 제작 설치된다. 그리고, 트러스를 형성하는 단위부재에는 트러스가 설치되는 위치 및 트러스에 가해지는 하중에 따라 다른 단면을 갖는 형강이 사용된다.The truss 10 manufactured generally consists of the upper chord 11, the lower chord 12, and the web material 13 connected therebetween, and each member is made by the method of screwing, clinching, welding, etc. Is fixed to each other. The truss 10 may be manufactured in various shapes according to the location of the structure to be installed, the flat truss is mainly installed on the bottom frame, the various trusses are manufactured and installed in the roof frame according to the shape of the roof. As the unit member forming the truss, a section steel having a different cross section is used depending on the position at which the truss is installed and the load applied to the truss.

도 2a 및 도 2b는 도 1에 도시된 트러스의 상하현재 및 웨브재로 이용되는 경량형강을 각각 나타낸 사시도들이다.2A and 2B are perspective views each showing a light steel used as a web material and a top and bottom chord of the truss shown in FIG.

도 1 내지 도 2b에 도시된 바와 같이, 종래기술에 따른 트러스(10)를 형성하는 상하현재 및 웨브재로는 롤포밍기 또는 절곡기에서 강판을 냉간성형하여 제작한 ㄷ경량형강, 립 ㄷ경량형강 등이 이용된다.As shown in Figures 1 to 2b, as the up-and-down chord and web material forming the truss 10 according to the prior art, the light weight steel, lip light weight produced by cold forming a steel sheet in a roll forming or bending machine Section steel and the like.

트러스의 구조성능은 상기와 같은 단위부재인 형강에 의해 좌우되는데, 구조부재인 경량형강은 용도 및 그것이 지지해야 하는 하중, 마감방법 등에 따라 웨브, 플랜지 및 립의 크기가 조정될 수 있고, 다양한 두께로도 형성된다.Structural performance of the truss is dependent on the section steel, the unit member as described above, and the lightweight member steel, which is a structural member, can be adjusted in size of the web, flange and lip according to the use and the load, finishing method, etc. Is also formed.

하지만, 상기와 같은 트러스(10)는 일정간격으로 이격된 상하현재(11, 12)의 사이에 웨브재(13)를 각각 접합하는데, 이런 종래기술은 단위부재를 하나하나씩 나사, 클린칭, 용접 등의 접합방법을 이용해 상호 결합해야 하는 불편함이 있다.However, the truss 10 as described above joins the web material 13 between the upper and lower chords 11 and 12 spaced apart at regular intervals, and the prior art screws, clinching and welding unit members one by one. There is an inconvenience in that they must be combined with each other using a bonding method.

그래서, 종래기술의 트러스(10)에는 시공성이 비교적 용이한 용접을 주로 이용하는데, 용접을 이용한 트러스의 접합방법은 단위부재가 상호 교차되는 복잡한 부위에 사용하기 어렵고, 용접을 시행한 후에 부식방지를 위한 도금처리를 부가적으로 해야 하는 문제점이 있다. Therefore, the truss 10 of the prior art mainly uses welding, which is relatively easy to construct, but the method of joining the truss using welding is difficult to use in complicated areas where the unit members cross each other, and corrosion protection is performed after the welding is performed. There is a problem that the plating process for additionally.

본 발명은 앞서 설명한 바와 같은 종래 기술의 문제점을 해결하기 위하여 제공된 것으로서, 롤포밍 가공하여 상하현재 및 웨브재가 일체화된 단위부재를 성형하고, 이러한 단위부재를 상호 접합함으로써, 시공성을 향상시키는 트러스를 제공하는 데 그 목적이 있다.The present invention is provided to solve the problems of the prior art as described above, by forming a unit member in which the upper and lower chords and the web material is integrated by roll forming process, by providing a truss to improve the workability by bonding the unit members mutually Its purpose is to.

앞서 설명한 바와 같은 목적을 달성하기 위한 본 발명의 트러스는 일정한 길이로 절단된 강판의 폭방향 양 끝단부가 일측방향으로 두 번 이상 각각 절곡되어 상현부와 하현부를 구성하고, 절곡되지 않은 강판의 중간 부위가 웨브를 구성하는 일체형 단위부재를 1쌍 포함한다. 그리고, 본 발명은 상기 단위부재 한 쌍을 상기 웨브가 상호 대향하게 접하도록 위치시키고, 돌출된 상기 상하현부가 상호 겹치게 접합하여 폐단면을 각각 구성한다.In the truss of the present invention for achieving the object as described above, both ends of the width direction of the steel sheet cut to a certain length is bent two or more times in one direction each to form an upper and lower portions, the middle portion of the steel sheet not bent It includes a pair of unitary unit members constituting the web. And, in the present invention, the pair of unit members are positioned so that the webs face each other, and the protruding upper and lower portions overlap each other to form a closed cross section.

또한, 상기 단위부재 한 쌍은 상호 핀접합되는 것이 바람직하다.In addition, it is preferable that the pair of unit members are pin-bonded to each other.

아래에서는 본 발명에 따른 롤 포밍 가공된 단위부재로 구성된 트러스의 양호한 실시예를 첨부한 도면을 참조로 하여 상세히 설명하겠다.Hereinafter, with reference to the accompanying drawings, a preferred embodiment of a truss consisting of a roll-formed unit member according to the present invention will be described in detail.

도 3은 본 발명의 한 실시예에 따른 트러스를 구성하는 단위부재의 사시도이고, 도 4는 도 3에 도시된 상호 마주보는 한 쌍의 단위부재들을 나타낸 측면도이고, 도 5는 도 4에 도시된 한 쌍의 단위부재들이 접합된 본 발명에 따른 트러스의 사시도이고, 도 6은 도 5에 도시된 트러스의 측면도이다.3 is a perspective view of a unit member constituting a truss according to an embodiment of the present invention, Figure 4 is a side view showing a pair of mutually opposite unit members shown in Figure 3, Figure 5 is shown in Figure 4 6 is a perspective view of a truss according to the present invention in which a pair of unit members are joined, and FIG. 6 is a side view of the truss illustrated in FIG. 5.

도 3 내지 도 6에 도시된 바와 같이, 본 발명의 트러스(20)는 롤포밍기에서 박판 자재가 냉간성형 및 천공을 통해 상하현부(21, 22) 및 웨브(23)를 갖는 단위부재로 제조되고, 상기와 같은 한 쌍의 단위부재가 상호 핀접합됨으로써 완성된다.As shown in Figures 3 to 6, the truss 20 of the present invention is made of a unit member having the upper and lower port portions 21, 22 and the web 23 through the cold forming and punching the sheet material in the roll forming machine The pair of unit members as described above is completed by pin bonding with each other.

본 발명의 트러스(20)는 한 쌍의 단위부재로 구성되는데, 이런 단위부재는 상하현부(21, 22) 및 웨브(23)로 이루어진 단면형상을 갖는다. 단위부재의 상하현부(21, 22) 및 웨브(23)는 종래기술에 따른 트러스에서 상하현재와 웨브재의 역할을 각각 수행한다. Truss 20 of the present invention is composed of a pair of unit members, the unit member has a cross-sectional shape consisting of the upper and lower strings (21, 22) and the web (23). The upper and lower chord portions 21 and 22 and the web 23 of the unit member each play a role of an up-down chord and web material in the truss according to the prior art.                     

단위부재는 일정한 길이로 절단된 강판을 성형 제작하며, 특히 본 발명의 트러스(20)에는 박판자재를 사용한다. 이런 단위부재의 상하현부(21, 22)는 박판자재의 폭방향 양 끝단부가 일측방향으로 두 번 이상 각각 절곡된 형상으로, 상하현부(21, 22)의 절곡된 양 끝단부는 다른 단위부재와의 접합을 위해 타측방향으로 웨브(23)보다 더 돌출되게 형성된다.The unit member is manufactured by molding a steel sheet cut to a certain length, and in particular, the truss 20 of the present invention uses a thin plate material. The upper and lower stringers 21 and 22 of the unit member have a shape in which both ends of the width direction of the thin plate material are bent at least twice in one direction, and both bent ends of the upper and lower stringers 21 and 22 are different from each other. It is formed to protrude more than the web 23 in the other direction for bonding.

그리고, 단위부재에서 절곡되지 않은 웨브(23)에는 단위부재의 길이방향을 따라 펀칭에 의해 다수개의 천공부(24)들이 형성된다. In addition, a plurality of perforations 24 are formed in the web 23 which is not bent in the unit member by punching along the longitudinal direction of the unit member.

상기와 같이 구성된 단위부재는 도 5에 도시된 바와 같이 다른 단위부재와 접합된다. 즉, 한 쌍의 단위부재들은 웨브(23)들이 상호 대향되게 접하고, 단위부재들의 돌출된 상하현부(21, 22)는 상호 겹치게 접하여 상하부에 폐단면을 구성하게 된다. 그리고, 단위부재들은 한쌍의 상하현부(21, 22)들과 웨브(23)들이 각각 핀접합된다. 이렇게 접합된 단위부재들은 트러스(20)로 사용된다.The unit member configured as described above is joined to another unit member as shown in FIG. 5. That is, the pair of unit members are in contact with the webs 23 are opposed to each other, the protruding upper and lower portions 21, 22 of the unit members are in contact with each other overlapping the upper and lower parts to form a closed cross-section. In addition, the unit member is a pair of upper and lower port portions 21 and 22 and the web 23 is pin-bonded, respectively. The unit members thus joined are used as trusses 20.

또한, 일반적으로 구조물에 사용되는 트러스에는 상하현재에 하중이 더 많이 작용하고, 웨브재에는 비교적 적게 작용하기 때문에, 본 발명의 트러스(20)에는 단위부재의 상하현부(21, 22)를 다양한 형상으로 절곡하여 강성을 보강할 수도 있다. 즉, 단위부재가 접합된 트러스(20)는 트러스(20)에 작용하는 처짐과 휨모멘트에 따라, 상하현부(21, 22)의 형상을 삼각형 또는 직사각형으로 제작할 수 있다.In addition, since the load is applied to the truss used for the structure in the upper and lower chords, and relatively less to the web material, the truss 20 of the present invention has various shapes of the upper and lower chords 21 and 22 of the unit member. It can also be bent to reinforce rigidity. That is, the truss 20 to which the unit member is bonded may form the shape of the upper and lower string portions 21 and 22 in a triangle or a rectangle according to the deflection and the bending moment acting on the truss 20.

또한, 본 발명의 트러스(20)는 평트러스, 경사트러스 등과 같이 설치용도에 따라 다양한 형상으로 제작할 수도 있는데, 이런 경우에는 단위부재의 상하현부(21, 22)를 박판자재의 양 끝단부를 경사지게 절곡하고, 단위부재의 천공 부(24)를 그 크기에 따라 펀칭한다.In addition, the truss 20 of the present invention may be manufactured in various shapes according to the installation purpose, such as flat truss, inclined truss, etc. In this case, the upper and lower strings 21, 22 of the unit member is bent inclined at both ends of the sheet material. And the punching part 24 of a unit member is punched according to the magnitude | size.

앞서 상세히 설명한 바와 같이, 본 발명의 롤 포밍 가공된 단위부재로 구성된 트러스는 종래기술과 달리 각 상하현재 및 웨브재를 접합철물이나 용접에 의해 하나씩 결합할 필요없이 롤포밍기에서 단위부재로 성형하고, 이런 단위부재 한 쌍을 상호 핀접합하기 때문에, 트러스의 제작이 용이해지며, 이로 인한 트러스의 설치 시공성이 향상되는 장점이 있다. As described in detail above, the truss composed of the roll-formed unit member of the present invention, unlike the prior art, each of the upper and lower chords and web material is molded into the unit member in the roll forming machine without the need to combine one by one by welding or welding Since the pairs of such unit members are pin-bonded to each other, fabrication of the truss is facilitated, thereby improving the installation construction of the truss.

이상에서 본 발명의 롤 포밍 가공된 단위부재로 구성된 트러스에 대한 기술사상을 첨부도면과 함께 서술하였지만, 이는 본 발명의 가장 양호한 실시예를 예시적으로 설명한 것이지 본 발명을 한정하는 것은 아니다. 또한, 이 기술분야의 통상의 지식을 가진 자이면 누구나 본 발명의 기술사상의 범주를 이탈하지 않는 범위 내에서 다양한 변형 및 모방이 가능함은 명백한 사실이다.








The technical idea of the truss composed of the roll-formed unit member of the present invention has been described above with reference to the accompanying drawings, but this is by way of example only and not intended to limit the present invention. In addition, it is obvious that any person skilled in the art can make various modifications and imitations without departing from the scope of the technical idea of the present invention.
