JOINT STRUCTURE AND JOINT METHOD OF FLOOR SLAB AND STEEL GIRDER
To eliminate a through-hole penetrating through a floor slab and improve workability in a joint structure of the floor slab and a steel girder.SOLUTION: A joint structure 1 of a floor slab and a steel girder has a steel girder 3, first and second precast floor slabs 2A and 2B installed adjacent to each other on the steel girder 3, a projecting body 6 provided on the upper surface of the steel girder 3, and mortar for joining the second floor slab 2B to the steel girder 3. The second floor slab 2B has a recess part 24 opened to the lower surface, the projecting body 6 is stored in the recess part 24, and the recess part 24 is filled with mortar. The first floor slab 2A has a first connection part 27A, the second floor slab 2B has a second connection part 27B, and the first connection part 27A and the second connection part 27B overlap each other in a ridge direction X to form a connection structure 28 between the first floor slab 2A and the second floor slab 2B. A distance d2 between the projecting body 6 and the side wall of the recess part 24 is larger than an overlap length d1 of the first and second connection parts 27A and 27B on the first floor slab 2A side in the ridge direction X.SELECTED DRAWING: Figure 6
【課題】床版と鋼桁の接合構造において、床版を貫通する貫通孔をなくし、かつ施工性を高める。【解決手段】床版と鋼桁の接合構造１は、鋼桁３と、鋼桁３の上に互いに隣接して設置されるプレキャスト製の第１及び第２の床版２Ａ，２Ｂと、鋼桁３の上面に設けられた突状体６と、第２の床版２Ｂを鋼桁３に接合するモルタルと、を有している。第２の床版２Ｂは下面に開口した凹部２４を有し、突状体６は凹部２４に収容され、凹部２４にモルタルが充填されている。第１の床版２Ａは第１の接続部２７Ａを有し、第２の床版２Ｂは第２の接続部２７Ｂを有し、第１の接続部２７Ａと第２の接続部２７Ｂが桁行方向に重なることで、第１の床版２Ａと第２の床版２Ｂとの間に接続構造体２８が形成される。突状体６と凹部２４の側壁との間隔ｄ２は、桁行方向Ｘにおける第１の床版側２Ａで、第１及び第２の接続部２７Ａ，２７Ｂの重なり長さｄ１より大きい。【選択図】図６
