PROBLEM TO BE SOLVED: To improve workability when installing a beam on a foundation girder.SOLUTION: Workability is improved since construction of bar arrangement and a form is obviated by comparing with a case where a beam installed on a foundation girder 50 is made of reinforced concrete by being formed as a structure for installing a steel frame beam 70 of a continuous beam structure on the foundation girder 50. The beam formation of a second beam 90 of the steel frame beam 70 can be lowered since a deformation quantity is reduced and stress is reduced since many fulcrums are included by comparing with a case where the steel frame beam 70 is a simple beam structure by forming the steel frame beam 70 as a gel bar beam. Thus, cost of the steel frame beam 70 is reduced.SELECTED DRAWING: Figure 1 【課題】基礎大梁に小梁を架設する場合の施工性を向上させる。【解決手段】基礎大梁５０の上に連続梁構造の鉄骨小梁７０を架設した構造とすることで、基礎大梁５０に架設する小梁が鉄筋コンクリート造の場合と比較し、配筋や型枠の施工が不要となるので、施工性が向上する。また、鉄骨小梁７０をゲルバー梁とすることで、鉄骨小梁７０が単純梁構造の場合と比較し、支点が多いので変形量が少なく応力が小さくなるので、鉄骨小梁７０の第二小梁９０の梁成を低くすることができる。よって、鉄骨小梁７０のコストが削減する。【選択図】図１
