    • A stress ribbon bridge using a vertical fiberboard and a precast composite fiber reinforced plastic deck is provided to construct a bridge economically and to extend the span length of a bridge by reducing the dead weight of a bridge deck and the horizontal tensile force required for bridge construction. A stress ribbon bridge(1) using a vertical fiberboard and a precast composite fiber reinforced plastic deck includes abutments(10) installed on two ends of the bridge, plural precast composite fiber reinforced plastic decks(20) placed and assembled between the abutments, two or more strap type vertical suspension fiberboards(30) installed between the abutments in the longitudinal direction of the bridge to support the bottom of the precast composite fiber reinforced plastic decks, and a prestress fiberboard(40) placed through the precast composite fiber reinforced plastic deck in the longitudinal direction of the bridge and tensed/anchored to apply tensile force on the precast composite fiber reinforced plastic deck. In addition, a curved projection is formed on a part where the precast composite fiber reinforced plastic deck and the suspension fiberboard are in contact to prevent the sudden change in curvature, thereby to prevent local stress concentration, and a low friction material such as Teflon is placed on a part where the precast composite fiber reinforced plastic deck and the suspension fiberboard are in contact or coated on the projection to minimize frictional stress between the precast composite fiber reinforced plastic deck and the suspension fiberboard.
    • 提供了一种使用垂直纤维板和预制复合纤维增强塑料甲板的应力带桥,经济地构造桥梁,并通过减小桥面板的自重和桥梁施工所需的水平张力来延长桥梁的跨距 。 使用垂直纤维板和预制复合纤维增强塑料甲板的应力带桥(1)包括安装在桥的两端的基台(10),多个预制复合纤维增强塑料甲板(20)放置并组装在基台之间,两个 或更多的带状垂直悬挂纤维板(30),其安装在桥的纵向方向的邻接处之间,以支撑预制复合纤维增强塑料甲板的底部,以及通过预制复合纤维增强塑料甲板放置的预应力纤维板(40) 在桥梁的纵向方向上并张紧/锚固,以对预制复合纤维增强塑料甲板施加拉力。 另外,在预制复合纤维增强塑料板和悬挂纤维板接触的部分上形成弯曲突起,以防止曲率突然变化,从而防止局部应力集中,并且诸如特氟隆的低摩擦材料 放置在预制复合纤维增强塑料甲板和悬挂纤维板与突起接触或涂覆在部分上,以最小化预制复合纤维增强塑料甲板和悬挂纤维板之间的摩擦应力。
