STEEL GIRDER AND FLOOR SLAB COUPLING STRUCTURE, COUPLING METHOD OF STEEL GIRDER AND FLOOR SLAB, AND REMOVAL METHOD OF FLOOR SLAB
PROBLEM TO BE SOLVED: To provide a composite girder in which a concrete floor slab can be easily removed from a steel girder.SOLUTION: A U-shaped screw-knotted reinforcing-bar 4 is inserted into a through hole 21a drilled on an upper flange 21 of a steel girder 2, and an upper nut member 5 and a lower nut member 6 are screwed with the screw-knotted reinforcing-bar 4 on the upper and lower sides of the upper flange 21, so that the steel girder 2 and a concrete floor slab 3 are made to be coupled by the screw-knotted reinforcing-bar 4 and the nut members 5, 6. the concrete floor slab 3 and the steel girder 2 are disengaged each other only by removing a bending part 4b on the lower part of the screw-knotted reinforcing-bar 4 by cutting, and removing the lower nut member 6 from the screw-knotted reinforcing-bar 4, so that the concrete floor slab 3 can be easily removed from the steel girder 2.SELECTED DRAWING: Figure 1
【課題】合成桁においてコンクリート床版を鋼桁から簡単に取り外すことができるようにする。【解決手段】鋼桁２の上フランジ２１に穿設した貫通孔２１ａにはＵ字状のねじ節鉄筋４を挿通すると共に、該上フランジ２１の上側と下側においては該ねじ節鉄筋４に上側ナット部材５と下側ナット部材６とを螺合しておき、これらのねじ節鉄筋４及びナット部材５，６によって該鋼桁２とコンクリート床版３とを結合するようにしておく。該ねじ節鉄筋４の下部の折れ曲がり部４ｂを切断により除去すると共に、該下側ナット部材６を該ねじ節鉄筋４から取り外すだけで、該コンクリート床版３と該鋼桁２との結合が解除されるので、該コンクリート床版３を該鋼桁２から簡単に取り外すことができる。【選択図】図１
