Simply supported girder bridge deck continuous structure and construction method
The invention relates to the technical field of bridge construction, in particular to a simply supported beam bridge deck continuous structure and a construction method.The simply supported beam bridge deck continuous structure comprises main beams and a bridge deck pavement layer, an expansion joint is reserved between every two adjacent main beams, prefabricated grooves are formed in the end faces of the ends, close to each other, of the two main beams, and a filling area is defined by the prefabricated grooves; the width of the filling area is gradually increased from bottom to top; the filling area is filled with concrete to form a connecting block; the bridge deck pavement layer comprises bridge deck slabs and a bridge deck connecting plate, the bridge deck slabs are symmetrically arranged relative to the sub-span line and connected with the top face of the main beam, the bridge deck connecting plate is located between the two bridge deck slabs and connected with the bridge deck slabs into a whole, and a gap exists between the bridge deck connecting plate and the connecting block. According to the bridge floor continuous structure of the simply supported girder bridge, the bridge floor connecting plates are separated from the main beams, and the filling areas filled with the concrete are arranged on the main beams, so that the rigidity of bridge floor connecting parts can be reduced, and structural cracking is delayed.
本发明涉及桥梁施工技术领域,尤其涉及一种简支梁桥桥面连续结构及施工方法,该简支梁桥桥面连续结构包括主梁和桥面铺装层,相邻两段主梁之间留有伸缩缝,且两段主梁相互靠近的一端端面设置有预制槽,预制槽围合形成填充区,填充区自下而上宽度逐渐变大,填充区内填充混凝土形成连接块;桥面铺装层包括桥面板和桥面连接板,桥面板相对于分跨线对称布置且与主梁顶面连接,桥面连接板位于两段桥面板之间并与桥面板连接为一体,桥面连接板与连接块之间存在间隙。上述简支梁桥桥面连续结构将桥面连接板与主梁分开,并在主梁这几件设置填充有混凝土的填充区,能够减小桥面连接部位的刚度,延缓结构开裂。
