Zusammenfassung: | To provide a junction structure of a highest floor and a junction method of a joint part of the highest floor capable of improving workability.SOLUTION: A junction structure 10 of a highest floor is provided with a steel concrete column 20 configured to embed steel bars in concrete 25 and a steel beam 30. The steel beam 30 is configured by intersecting two H-shaped steels 31, 35 perpendicular to each other. The H-shaped steels 31, 35 are provided with webs 32, 37, upper flanges 33, 38, and lower flanges 34, 39. A cover plates 17 is welded on the H-shaped steels 31, 35 to surround the column 20 at a joint part. Each of steel bars of the column 20 is composed of a main girder 21, fixation metal members 22 attached on an upper end surface of the main girder 21, and hoop reinforcements 23 positioned below the steel beam 30. The steel bars are arranged in a way that the upper surfaces of the fixation members 22 making upper end surface of the steel bars are placed between the upper flanges 33, 38 and the lower flanges 34, 39.SELECTED DRAWING: Figure 1
【課題】施工性を向上させることができる最上階の接合構造及び最上階の仕口部の接合方法を提供する。【解決手段】最上階の接合構造10は、鉄筋をコンクリート25に内蔵した鉄筋コンクリート造の柱20と、鉄骨梁30とを備える。鉄骨梁30は、2つのH形鋼31,35を直角に交差して構成される。H形鋼31,35は、ウェブ32,37と、上側フランジ33,38と、下側フランジ34,39とを有する。H形鋼31,35には、仕口部における柱20を囲むふさぎ板17が溶接されている。柱20の鉄筋は、主筋21と、主筋21の上端部に取り付けられた定着金物22と、鉄骨梁30より下方に配置されたフープ筋23から構成される。鉄筋の上端面である定着金物22の上面部を、上側フランジ33,38と、下側フランジ34,39との間に位置するように、鉄筋を配置する。【選択図】図1 |
