PROBLEM TO BE SOLVED: To provide a composite beam in which the integration property of a floor slab and a main girder is enhanced.SOLUTION: A composite beam includes a main girder 20 which supports a floor slabs 30A, 30B and a cross beam 27 which is attached to the main girder 20 and fixes the floor slabs 30A, 30B. The cross beam 27 and the floor slabs 30A, 30B are fixed to each other by a stud 27d. The stud 27d is fixed to the cross beam 27 and extends into the floor slabs 30A, 30B. The main girder 20 has vertical girders 21A, 21B to which the cross beam 27 is attached, and the vertical girders 21A, 21B and the floor slabs 30A, 30B are fixed by a slip preventive member. |
