JUNCTION STRUCTURE FOR STRUCTURAL STEEL
PROBLEM TO BE SOLVED: To provide a junction structure for a structural steel that absorbs expansion/contraction of the structural steel due to a temperature change, and ensures rigidity in a direction orthogonal to a longer-side direction of the structural steel.SOLUTION: The junction structure for a structural steel is applied to a junction connecting an edge of a structural steel to a fixed structure. For example, a member to which the structural steel of the fixed structure is connected is a girder 1, and the structural steel is a beam 2. A connection metal fitting 3 is disposed on the girder 1, for connecting the beam. The connection metal fitting 3 comprises a pair of perpendicular plates 4 disposed in a prescribed direction leaving an interval, the prescribed direction being a longer-side direction of the girder 1, and a deformation-permitting plate 5 disposed between edges at a tip of the two perpendicular plates 4 on the beam 2 side, the deformation-permitting plate being not connected directly with the girder 1. An end of the beam 2 is connected to the deformation-permitting plate 5. The deformation-permitting plate 5 has cut-out holes 10A to 10D formed for reducing rigidity, and is configured as a truss structure.SELECTED DRAWING: Figure 1
【課題】 鉄骨が温度変化により伸縮しても、その伸縮を吸収することができ、かつ鉄骨の長手方向に垂直な方向の剛性も確保することができる鉄骨の接合構造を提供する。【解決手段】 この鉄骨の接合構造は、固定構造体に鉄骨の一端を接合する接合部に適用される。例えば、固定構造体の鉄骨が接合される部材は大梁１であり、鉄骨は小梁２である。大梁１に小梁接合用の接合金物３が設けられる。接合金物３は、大梁１の長手方向である所定方向に間隔を開けて配置された一対の垂直板４と、両垂直板４の小梁２側の先端縁間に設けられ大梁１とは直接には非接合である変形許容板５とでなる。小梁２の一端が、変形許容板５に接合される。変形許容板５は、剛性低下用の切抜孔１０Ａ〜１０Ｄを設けてトラス構造とする。【選択図】 図１
