조립식 건축용 트러스빔{ASSEMBLY CONSTRUCTION TRUSS BEAM}Prefabricated building truss beams {ASSEMBLY CONSTRUCTION TRUSS BEAM}

본 발명은 조립식 건축용 트러스빔의 개량에 관한 것으로서, 특히 상현재와 하현재를 T바나 H형강 또는 두개의 앵글이 아닌 웨브, 즉 지지편이 2개인 "ㅛ"형상을 가진 일명 "ㅛ"바를 사용하여 상현재와 하현재를 구성하고, 상기 상,하현재 사이에 위치하는 수직재와 사재를 각파이프로 구성되게 하되, 상기 각파이프를 "ㅛ"형의 상,하현재가 이를 견고히 지탱할 수 있게 하여, 건축구조물의 조립시 강성을보강케 함과 동시에 진동과 비틀림에 대한 응력이 우수하도록 한 것이다.The present invention relates to an improvement of a prefabricated truss beam, in particular, using the upper chord and the lower chord by using a T bar or H-beam or a two-angle web, that is, a "ㅛ" bar having a "ㅛ" shape having two support pieces. The upper and lower chords are constructed, and the vertical and yarns positioned between the upper and lower chords are composed of square pipes, and the upper and lower chords of the "ㅛ" type can be firmly supported, thereby constructing It is to strengthen the stiffness when assembling the structure and to make excellent stress against vibration and torsion.

일반적으로 트러스빔은 상현재와 하현재 사이에 수직재와 사재가 조립되는 구조로서, 트러스빔에 작용하는 모든 하중을 압축과 인장력으로만 작용토록 구성되어 있어 휨이 발생하지 않을 뿐 아니라, 상현재와 하현재 사이의 간격이 동일하다면 적은 량의 소재로 보다 견고한 건축자재를 얻을 수 있다.In general, the truss beam is a structure in which the vertical material and the yarn are assembled between the upper chord and the lower chord, and all the loads acting on the truss beam are configured to act only by compression and tensile force, so that bending does not occur. If the spacings between the two chords are the same, more solid building materials can be obtained with less material.

또한 상하플랜지 사이에 웨브가 용접구성되는 주름보나 용접빔의 경우 상하플랜지 사이의 높이에 제약을 받지만, 트러스빔의 경우 수직재와 사재로 사용되는 부재의 길이만 길게 하면 상현재와 하현재 사이의 높이, 즉 간격을 원하는 높이로 제작할 수 있어 설계의 다양성을 기대할 수 있으며, 교량이나 터널, 건축용 자재등 다용도로 널리 사용되고 있다.In addition, the height between the upper and lower chords is limited by the height between the upper and lower flanges in the case of corrugated beams or weld beams where the web is welded between the upper and lower flanges. In other words, the gap can be manufactured to the desired height, so the diversity of the design can be expected, and it is widely used for various purposes such as bridges, tunnels, and building materials.

그러나 종래 일반적으로 사용되고 있는 트러스빔의 경우 여러 형태의 제품들이 제공되고 있으나, 상현재와 하현재 사이에 구성되는 수직재와 사재의 결속수단이 취약하여 진동이나 비틀림에 대한 내구성이 떨어지게 되는 단점이 있다.However, in the case of the truss beam generally used in general, various types of products are provided. However, since the binding means of the vertical member and the member constituted between the upper and lower chords is weak, the durability against vibration or torsion is reduced.

또한 이러한 단점을 시정하기 위한 수단으로서, 상,하현재를 구성하는 받침편 중앙에 단일지지편이 용접구성되게 한 "ㅗ"형으로 구성하고, 상기 지지편 상에 편철바로 구성된 수직재와 사재를 용접구성한 트러스빔이 제공된 바 있으나, 단일로 된 지지편의 강성 및 플랜지 1/2만큼의 플랜지 자굴이 발생하여 구조적으로도 취약할 뿐 아니라 용접부위 및 편철로 된 수직재와 사재의 강성이 취약하여 견고한 건축구조물의 조립에 난점이 따르게 되는 등의 문제가 있는 것이었다.In addition, as a means for correcting the above disadvantages, a single support piece is welded in the center of the support piece constituting the upper and lower chords, and is formed in a "ㅗ" type, and welded vertical material and yarn material composed of a braided bar on the support piece Although truss beam has been provided, it is not only structurally weak due to the rigidity of the single support piece and the flange magnetization of the flange 1/2, but also the weakness of the welded part and braided vertical material and sand material. There were problems such as difficulty in assembly.
