CONCRETE FILLED STEEL PIPE MEMBER, JOINT STRUCTURE AND JOINT METHOD
To provide a technology which eliminates the necessity of welding regarding the joint of a CFT member and a reinforced concrete member.SOLUTION: A concrete filled steel pipe (CFT) member is used for a beam and a girder of an RC viaduct 4 for a railway. A CFT beam 10H is a concrete filled steel pipe member which is joined to a slab 50 (reinforced concrete member) placed at the site and it includes: insertion hole parts 12 provided on a joint surface with the slab 50 of a steel pipe 11; displacement prevention reinforcing bars 20 in which insertion parts 21 on both ends are inserted into the insertion hole parts 12, a connection part 23 for connecting the insertion parts 21 on both ends are in a state of being outside of the insertion hole parts 12, and the connection part 23 is embedded in the slab 50; and a filled part 32 inside the steel pipe filled with concrete.SELECTED DRAWING: Figure 2
【課題】ＣＦＴ部材と鉄筋コンクリート部材との接合に係り溶接を不要とする技術を提供すること。【解決手段】鉄道用ＲＣ高架橋４の梁や桁に、コンクリート充填鋼管（ＣＦＴ）部材を用いる。ＣＦＴ梁１０Ｈは、現場で打設されるスラブ５０（鉄筋コンクリート部材）に接合するコンクリート充填鋼管部材であって、鋼管１１のスラブ５０との接合面に設けられた挿入孔部１２と、両端の差込部２１が挿入孔部２１に挿入され、両端の差込部２１を連結する連結部２３が挿入孔部１２の外に出た状態とされて、当該連結部２３がスラブ５０内に埋設されるズレ止め鉄筋２０と、コンクリートが充填された鋼管内部の充填部３２と、を備える。【選択図】図２
