Construction method of bridge deck continuous structure of simply supported girder bridge
The invention relates to a construction method of a bridge deck continuous structure of a simply supported girder bridge. The construction method comprises the steps that S1, chiseling treatment is performed on the top face of a girder; S2, reinforcing steel bars are bound between the ends of the adjacent main beams, concrete is poured, the reinforcing steel bars and the reinforcing steel bars at the ends of the main beams are bound together, the reinforcing steel bars are bound in multiple layers, a layer of concrete is poured after a layer of reinforcing steel bars are bound, the reinforcing steel bars of the upper layer are bound after the concrete is dried, then the concrete of the upper layer is poured, and circulation is performed in sequence; pouring of the wet joint is completed until the poured concrete layer is flush with the top of the main beam; S3, U-shaped horizontal stress plates are installed at the tops of the adjacent main beams correspondingly, notches of the horizontal stress plates face downwards, reinforcing steel bars are bound between the two horizontal stress plates, and then connecting plates are poured; and S4, bridge deck slab steel bars are bound, a concrete bridge deck slab is poured, and the concrete bridge deck slab covers the connecting plate and the horizontal stress plate. The method has the effect of reducing concrete cracking at the bridge deck continuous position of the simply supported girder bridge.
本发明涉及一种简支梁桥桥面连续构造的施工方法，其包括步骤S1、在主梁的顶面做凿毛处理；S2、在相邻的主梁的端头之间绑扎钢筋并浇筑混凝土，钢筋与主梁的端部钢筋绑扎在一起，钢筋分多层绑扎，绑扎一层钢筋后浇筑一层混凝土，待混凝土干燥后再绑扎上一层的钢筋，然后再浇筑上一层的混凝土，依次循环，直至浇筑的混凝土层与主梁的顶部平齐，完成湿接头的浇筑；S3、在相邻的主梁的顶部分别安装U型的水平应力板，水平应力板的槽口向下，并在两块水平应力板之间绑扎钢筋，然后浇筑连接板；S4、绑扎桥面板钢筋，并浇筑混凝土桥面板，混凝土桥面板将连接板和水平应力板覆盖。本申请具有减少简支梁桥桥面连续处混凝土开裂的效果。
