PRE-STRESSED CONCRETE FLOOR SLAB AND CONSTRUCTION METHOD FOR FLOOR SLAB USING PRE-STRESSED CONCRETE FLOOR SLAB
To provide a pre-stressed concrete floor slab capable of facilitating the improvement of earthquake resistance of the entire bridge by reducing the weight of the floor slab.SOLUTION: A pre-stressed concrete floor slab 1 using fiber reinforcement concrete, comprising a plate portion 2, and a lattice-like rib 3 composed of a vertical rib 31 and a lateral rib 32 formed on the underside of the plate portion 2, in which pre-stress is introduced to the vertical rib 31 by post-tensioning system, and pre-stress is introduced to the lateral rib 32 by pretension system.SELECTED DRAWING: Figure 1
【課題】床版の軽量化による橋梁全体の耐震性の向上を図ることが可能なプレストレストコンクリート床版を提案する。【解決手段】繊維補強コンクリートを用いたプレストレストコンクリート床版１であって、板部２と、板部２の下面に形成された縦リブ３１および横リブ３２とからなる格子状リブ３とを備え、縦リブ３１はポストテンション方式によってプレストレスが導入されていて、横リブ３２にはプレテンション方式によってプレストレスが導入されている。【選択図】図１
