STEEL CONCRETE COMPOSITE BEAM USING PROFILED PLATE

摘要

The present invention relates to a steel concrete composite beam using a molding plate which has internal protrusions integrated by building an open box shape through assembling unit steel plate sections and pouring concrete onto the box. A preferred embodiment of the present invention includes: a steel beam; and the concrete which is poured into the internal space of the steel beam. The steel beam includes: a vertical support formed in the vertical direction; an upper support unit and a lower support unit which are formed by being extended to a horizontal direction perpendicular to the upper and lower ends of the vertical support; a pair of side surface units which has Z-shaped sections comprising the coupling units formed by being extended from the end unit of the lower support in the upward direction and has protrusion units which comprises two vertical pieces which are curved to the upper part from the center of the lower support unit and horizontal pieces connecting the upper ends of the vertical units. The steel beam also has a box-shaped section with an opening on the upper part by coupling the coupling units of the side surface units to come in contact with each other.
