FORMWORK AND INSTALLATION METHOD OF PRECAST FLOOR SLAB
To provide a formwork capable of improving the workability of laying precast floor slabs on steel girders in the replacement of deck slabs while improving the quality after installation.SOLUTION: The formwork is used for forming a filling space for filler by blocking a gap between an upper flange of a steel girder and a precast floor slab. The formwork includes a weir board having a surface that abuts the edge of the upper flange and abuts against the underside of the precast floor slab; and a support bracket for supporting the weir board. The support bracket includes: a floor slab attachment to be attached to the underside of the precast floor slab; a weir board abutment abutting the rear surface of the weir board; and a steel girder abutment that abuts the underside of the weir board and the underside of the upper flange of the steel girder. The weir board is made of a material that has resilience.SELECTED DRAWING: Figure 3
【課題】床版取替工事において、鋼桁にプレキャスト床版を敷設する際の作業性向上と、敷設後の品質向上を図ることである。【解決手段】鋼桁の上フランジとプレキャスト床版との間の隙間を塞ぎ、充填材の充填空間を形成する型枠であって、前記上フランジの縁部に当接する表面を備えるとともに、前記プレキャスト床版の下面に当接するせき板と、該せき板を支持する支持金物と、を備え、該支持金物は、前記プレキャスト床版の下面に取り付けられる床版取付部と、前記せき板の背面に当接するせき板当接部と、前記せき板の下面及び前記鋼桁の上フランジ下面に当接する鋼桁当接部と、を含み、前記せき板が、復元性を有する材料よりなることを特徴とする。【選択図】図３
