WIDENING STRUCTURAL BODY, WIDENING STRUCTURE, FLOOR SLAB WIDENING CONSTRUCTION METHOD, AND FLOOR SLAB RENEWAL METHOD
To provide a widening structural body being light-weight and capable of effectively utilizing rigidity, a widening structure using the same, a floor slab widening construction method, and a floor slab renewal method.SOLUTION: A widening structural body includes additional girders and wall balustrades. The additional girders include floor slabs installed with wall balustrades, inner girder parts that project below the floor slabs at one end of the floor slabs, and outer girder parts that project in the vertical direction of the floor slabs at the other end of the floor slabs. The wall balustrades are installed on the floor slabs. A widening structure is a structure of a floor slab widened using the widening structural body of the present invention. A floor slab widening construction method is a floor slab widening construction method for widening an existing floor slab using the widening structural body of the present invention. A floor slab renewal method is a method of renewing an existing floor slab to a new floor slab using the widening structural body of the present invention.SELECTED DRAWING: Figure 1
【課題】 軽量でかつ剛性を有効にかせぐことのできる拡幅用構造体と、それを用いた拡幅構造、床版拡幅工法及び床版更新工法を提供する。【解決手段】 本発明の拡幅用構造体は追加桁と壁高欄を備えている。追加桁は、壁高欄が設置された床版部と床版部の一端側に床版部よりも下側に突出する内桁部と床版部の他端側に床版部の上下方向に突出する外桁部を備えている。壁高欄は床版部上に設置されている。本発明の拡幅構造は、本発明の拡幅用構造体を用いて拡幅された床版の構造である。本発明の床版拡幅工法は、本発明の拡幅用構造体を用いて既設床版を拡幅する床版拡幅工法である。本発明の床版更新工法は、本発明の拡幅用構造体を用いて既設床版を新設床版に更新する工法である。【選択図】図１
