STRUCTURAL STEELWORK STRUCTURE

PROBLEM TO BE SOLVED: To provide a structural steelwork structure.SOLUTION: An improved structure of a steel structure in a reinforced concrete structure is formed by overlapping a box girder unit having reinforcements, a steel column box unit, and a column-beam joint box unit each other. Side plates/end plates of the box unit have through holes for pouring concrete, and the box unit can be used directly as a concrete form. Accordingly, workability of cement injection and compaction is improved and a phenomenon such as nest box, exfoliation, or floating is hard to occur, and furthermore performance of a beam-column connection (for example, better restriction performance) can be improved. By applying the present invention, construction speed, convenience, and accuracy of the beam-column connection are improved, safety thereof can be better ensured, and man-hours as well as construction period therefor can be reduced.
