<p>The present invention relates to a steel-concrete composite beam with a cover having an internal shear connection unit formed thereon, wherein the internal shear connection unit is formed by assembling a unit section, which is formed by a steel sheet, to form a box and filling concrete in the box. According to an embodiment of the present invention, the steel-concrete composite beam comprises a steel beam, a cover, and concrete. The steel beam has a box-shape cross section whose upper part is opened and which is formed by making a side unit come in close contact with a protrusion coupling unit, wherein the side unit includes a vertical support unit vertically formed to have a W-shaped section whose edges are at right angles to each other; upper and lower support units extended from the upper and lower ends of the vertical support unit to be bent horizontally to cross each other; and the protrusion coupling unit extended from the end of the lower support unit and vertically bent downwards. The steel beam is formed by combining a vertically-formed web to the lower end of a shear connection member, which has a cross section with a reversed-T shape, by placing the web and the end of the shear connection member between the protrusion coupling units. The cover comprises an upper plate formed in the longitudinal direction of the steel beam; a side plate extended downwards from one widthwise side end of the upper plate; a lower plate extended horizontally from the lower end of the side plate to the outside to have a smaller width than that of the upper support unit of the side unit; and a side cap including a shear end connection unit extended downwards from the other widthwise side end of the upper plate. The cover is formed by combining the side cap to the upper plate of the shear connection unit of the side cap, and has the lower plates mounted on the upper support units of the side unit to be combined to each other. The concrete is filled inside the steel beam in a construction site and moves with the steel beam.</p> |
