JOINT STRUCTURE BETWEEN STEEL GIRDER AND PRECAST FLOOR SLAB
To provide a joint structure between a steel girder and a precast floor slab capable of being constructed in a short period of time and resisting shearing force in a bridge axial direction and bending moment in a direction orthogonal to a bridge axis without causing sectional deficit of the steel girder.SOLUTION: In a joint structure 1 between a steel girder and a precast floor slab for joining the steel girder 2 and the precast floor slab 3 placed on the steel girder 2, the steel girder 2 and the precast floor slab 3 are joined by using a stud bolt 4 welded to an upper flange 20 of the steel girder 2 to attach a pair of steel jigs 5, 5 with an L-shaped cross section having a bottom part 50 and a rising part 51 to both edges of an upper surface 2a of the upper flange 20, projecting an anti-slip steel material 30 having a side view U-shaped part that surrounds at least three parts of left, right, and bottom parts on a lower surface 3a of the precast floor slab 3, inserting a connection bolt 6 between the pair of steel jigs 5, 5 and fastening the same to the rising part 51, and inserting the connection bolt 6 into the anti-slip steel material 30 having the side view U-shaped part.SELECTED DRAWING: Figure 1
【課題】短期間で施工が可能で、鋼桁を断面欠損せずに、橋軸方向せん断力にも橋軸直角方向曲げモーメントにも対抗することができる鋼桁とプレキャスト床版との接合構造を提供する。【解決手段】鋼桁２と、この鋼２桁上に載置されたプレキャスト床版３と、を接合する鋼桁とプレキャスト床版との接合構造１において、鋼桁２の上フランジ２０の上面２ａの両縁に、この上フランジ２０に溶殖されたスタッドボルト４で底面部５０と立上り部５１とを有する断面Ｌ字状の一対の鋼製治具５，５を取り付け、プレキャスト床版３の下面３ａに、少なくとも左右及び下方の三方を囲む側面視Ｕ字状部を有するずれ止め鋼材３０を突設し、一対の鋼製治具５，５の間に、連結ボルト６を挿通して立上り部５１に止め付け、連結ボルト６を側面視Ｕ字状部を有するずれ止め鋼材３０に挿通することで、鋼桁２とプレキャスト床版３とを接合する。【選択図】図１
