FIXED STRUCTURE OF MAIN GIRDER AND PRECAST SLAB AND METHOD OF FIXING MAIN GIRDER AND PRECAST SLAB
To provide a fixed structure of a main girder and a precast slab capable of improving the durability.SOLUTION: A fixed structure 1A of a main girder 2 and a precast floor slab 3A, includes: the main girder 2 having projections 5 protruding upwards; the precast floor slab 3A that has a housing 8 that accommodates the projections 5 on a bottom surface 6; and a filler 9 that fills the housing 8 accommodating the protrusions 5. The length of the path from an upper surface 7 of the precast floor slab 3A to a lower surface 6 of the precast floor slab 3A along a boundary surface 10 between the housing 8 and the filler 9 is longer than a distance d between the upper surface 7 and the lower surface 6 of the precast floor slab 3A. Thus, the intrusion route of water and salt due to rainwater from the upper surface 7 of the precast floor slab 3A to the lower surface 6 becomes longer than the thickness of the precast floor slab 3A. With this, the durability of the fixed structure 1A between the main girder 2 and the precast floor slab 3A is improved.SELECTED DRAWING: Figure 3
【課題】主桁とプレキャスト床版との固定構造の耐久性を向上させる。【解決手段】上方に突出した突出部５を有する主桁２と、下面６に突出部５を収容する収容部８を有するプレキャスト床版３Ａと、突出部５を収容した収容部８を充填する充填材９とを備えた主桁２とプレキャスト床版３Ａとの固定構造１Ａにおいて、プレキャスト床版３Ａの上面７から収容部８と充填材９との境界面１０に沿ってプレキャスト床版３Ａの下面６へと至る経路の長さが、プレキャスト床版３Ａの上面７と下面６との距離ｄよりも長いため、プレキャスト床版３Ａの上面７から下面６への雨水等による水分や塩分の侵入経路がプレキャスト床版３Ａの厚さよりも長くなり、主桁２とプレキャスト床版３Ａとの固定構造１Ａの耐久性を向上させることができる。【選択図】図３
