<P>PROBLEM TO BE SOLVED: To prevent torsional deformation of an H-shaped steel girder from being caused by self-weight of a beam and weight of a floor slab, even when the beam has a long span. <P>SOLUTION: A steel beam joint structure 10 makes an H-shaped steel beam 12 and an H-shaped steel girder 14 joined together. The beam 12 is laid between the girders 14, and both ends are joined to the girders 14. Joining insertion portions 28 are attached to both the ends of the beam 12, respectively. The insertion portion 28 is formed of H-shaped steel, and the length L1 of the insertion portion 28 is set equal in dimension to the width of a flange 14F of the girder 14. An end of the insertion portion 28 is joined to an end member 30 which is fixed to an end surface of the beam 12. An extension material 32 is provided in a position to extend the flange of the insertion portion 28. The girder 14 is laid between columns, and a web 14W of the girder 14 is provided with an opening 18 into which the insertion portion 28 of the beam 12 is to be inserted. A reinforcing member 20 for reinforcing the opening 18 is joined to the periphery of the opening 18. <P>COPYRIGHT: (C)2012,JPO&INPIT |
