JOINING STRUCTURE OF PRECAST WALL HANDRAIL
PROBLEM TO BE SOLVED: To shorten a construction period of its construction, in a joining structure for joining a precast wall handrail to a floor slab.SOLUTION: A side end part 20B and a side end part vicinal area 20C of a floor slab 20 are formed in a step-down shape to its general part 20A. While arranging a first reinforcement 22 projecting from its outside surface 20Aa in the general part 20A of the floor slab 20, a second reinforcement 32 projecting from a lower end part 30Ab1 of an inside surface 30Ab of its handrail body part 30A is arranged in a precast wall handrail 30 placed on an upper surface of the side end part 20B of the floor slab 20. Infilling concrete 40 is placed in a recessed space C formed of the lower end part 30Ab1 of the inside surface 30Ab of the handrail body part 30A, the outside surface 20Aa of the general part 20A of the floor slab 20 and an upper surface 20Ca of its side part vicinal area 20C, so that the precast wall handrail 30 is joined to the floor slab 20. Installation of an outer form is obviated thereby, and bar arrangement work of a reinforcement bar 42 is executed as work on a horizontal plane.
【課題】プレキャスト壁高欄を床版に接合するための接合構造において、その施工の工期短縮を図る。【解決手段】床版２０の側端部２０Ｂおよび側端部近傍領域２０Ｃを、その一般部２０Ａに対して段下がりで形成する。また、床版２０の一般部２０Ａに、その外側面２０Ａａから突出する第１の鉄筋２２を配筋する一方、床版２０の側端部２０Ｂの上面に載置されるプレキャスト壁高欄３０に、その高欄本体部３０Ａの内側面３０Ａｂの下端部３０Ａｂ１から突出する第２の鉄筋３２を配筋しておく。そして、高欄本体部３０Ａの内側面３０Ａｂの下端部３０Ａｂ１と、床版２０の一般部２０Ａの外側面２０Ａａと、その側端部近傍領域２０Ｃの上面２０Ｃａとで形成される凹部空間Ｃに間詰めコンクリート４０を打設することにより、プレキャスト壁高欄３０を床版２０に接合する。これにより外型枠の設置を不要とし、また補強鉄筋４２の配筋作業を水平面上での作業とする。【選択図】図９
