Abstract

PURPOSE: An improved steel frame beam for reducing bed height is provided to decrease the total construction depth of the steel concrete slab by adjusting the height of an angle bar, to produce conveniently by jointing the angle bar with welding or bolting, and to prevent local stress, bending or distortion by forming the unequal angle bar. CONSTITUTION: An improved steel frame beam(6) is manufactured by jointing an equal angle(8) or an unequal angle or more in the center of a web in an H-steel beam or an I-steel beam(7). Two equal or unequal angles are mounted on the center of the web of the H-steel beam or the I-steel beam, and construction is performed by mounting the precast slab. The construction depth of the total slab is adjusted by adjusting the height of the unequal angle freely according to the depth of the steel frame beam, the slab depth and the depth of the duct. Bending and torsion are prevented against local stress on the lower part of the middle flange by forming the unequal thick angle. Convenience is improved by jointing the unequal angle with welding or bolting.

Description

충고 감축을 위한 개량 철골보{Modified Wide-flange Steel Beam for Reduction of Story Height}Modified Wide-flange Steel Beam for Reduction of Story Height

본 발명의 층고 감축을 위한 개량 철골보는 기존의 H형강보나 I형강보(1) 대신 개량형 철골보를 사용함으로서 층고 감축, 생산성 및 구조성능을 획기적으로 향상시킨 발전된 층고 감축을 위한 개량 철골보에 관한 것이다.Improved steel ball for reducing the height of the present invention by using an improved steel ball instead of the conventional H-beam or I-shaped beam (1) relates to an improved steel beam for improved floor height reduction significantly improved the floor height reduction, productivity and structural performance.

기존의 H형강 또는 I형강보는 PC슬래브의 댑단부가 철골보 상부의 플랜지에 올려지므로 층고 증대의 문제점 등이 발생하였다. 본 발명의 개량 철골보는 등변 또는 부등변 ㄱ형강(Angle) 한 개 또는 두 개를 접합하여 이 위에 PC 슬래브를 올려 시공할 경우 전체 슬래브 시공깊이는 H형강보 깊이로 축소되므로 올려지는 슬래브와 토핑 콘크리트(19) 깊이 일부에 해당하는 층고 절감이 가능하다.Conventional H-beams or I-beams have a problem of increasing the height of the floor because the end of the PC slab is mounted on the flange of the upper steel cheolgolbo. Improved steel ball of the present invention when the construction of the PC slab by joining one or two of isosceles or isosceles a-shape (Angle), the overall slab construction depth is reduced to the depth of the H-beams, so the slab and topping concrete ( 19) It is possible to reduce the height above a part of the depth.

본 발명은 층고 절감이 가능하며, 휨과 비틀림에 효율적 단면을 유도하였고, 제작의 편리성 도모하며, 철골재에서 특히 문제시되는 국부응력(Local Stress)가 발생하지 않도록 고려한 "층고 감축을 위한 개량 철골보"를 제안하려한다. 본 발명의 개량 철골보(6)는 등변 또는 부등변 ㄱ형강(Angle) 한 개 또는 두 개를 접합하여 이 위에 PC 슬래브를 올려 시공이 가능한 개량 철골보이다.The present invention can reduce the height of the floor, induces efficient cross section in bending and torsion, promotes the convenience of production, and considers that local stress, which is particularly problematic in steel aggregates, is considered to be improved steel beam for reducing height. Try to suggest. The improved cheolgolbo 6 of the present invention is an improved cheolgolbo that can be constructed by joining one or two of isosceles or isosceles a-shape (Angle) to raise the PC slab thereon.

기존의 H형강보나 I형강보는 플랜지 위에 PC 슬래브를 올려 시공하도록 되어있다. 이 경우 전체 슬래브 시공깊이(construction depth)는 H형강 보 깊이에 올려지는 슬래브와 토핑 콘크리트 깊이를 포함한다. 기존의 변형된 철골보(2)의 경우 복부에 플레이트판(4)을 용접하고, 복부 플래이트와 하부 플랜지 사이에 스티프너(5)를 보강하는 형태로 이루어져 있다. 이는 복부 플레이트판과 스티프너의 용접작업이 반드시 필요하므로 제작성 및 생산성에 큰 단점이 있다. 아울러, 스티프너로 인한 국부응력이 발생할 수 있다.Conventional H-beams or I-beams are constructed by mounting a PC slab on a flange. In this case, the overall slab construction depth includes the slab and topping concrete depth that is raised to the H-beam depth. In the case of the conventional deformed cheolgolbo (2) it is made of a form for welding the plate plate 4 to the abdomen, the stiffener (5) between the abdomen plate and the lower flange. This requires a welding operation of the abdominal plate plate and the stiffener is a major disadvantage in manufacturability and productivity. In addition, local stress due to stiffeners may occur.

본 발명은 층고 감축으로 인한 공사비 절감에 기초하여 고려하였다. 공사비 절감은 부등변 ㄱ형강(Angle)의 높이를 자유롭게 조절함으로써 가능하다. 철골보깊이, 슬래브 깊이, 덕트 포함깊이의 크기에 따라 전체 슬래브 시공깊이를 조절하기 위하여 가장 최적인 부등변 ㄱ형강(Angle)의 높이에 대한 기술적 고려가 필요하다.The present invention has been considered based on the construction cost savings due to floor height reduction. The construction cost can be reduced by freely adjusting the height of the trapezoid A. In order to control the overall slab construction depth according to the size of steel beam depth, slab depth, and duct inclusion depth, technical considerations on the optimum height of anisotropic angle A should be considered.
