Method for connecting ballastless track steel beam top plate and concrete bridge floor
The invention relates to a method for connecting a ballastless track steel beam top plate and a concrete bridge deck, which comprises the following steps of: breaking and parting a concrete bridge deck in a certain range along the bridge direction to form an independent bridge deck, and dividing the independent bridge deck into a fixed area, a transition area and a movable area; wherein strong connection is formed between the concrete bridge deck and the steel beam top plate in the fixed area, weak connection is formed between the concrete bridge deck and the steel beam top plate in the transition area, and the weak connection refers to connection allowing small deformation between the concrete bridge deck and the steel beam top plate; and filling connection is formed between the concrete bridge deck and the steel beam top plate in the moving area, and the filling connection means that large horizontal deformation is allowed to occur between the concrete bridge deck and the steel beam top plate. The method has the advantages that the whole bridge deck slab can be prefabricated, the construction period is guaranteed, the stress of the concrete bridge deck slab in the bridge direction is released, concrete cracking is reduced, follow-up maintenance work is relieved, the bridge deck slab is constructed in a blocking mode, construction is convenient and fast, and dependence on large machines is small.
本发明涉及一种无砟轨道钢梁顶板与混凝土桥面连接方法，混凝土桥面板沿其顺桥向以一定范围断开分缝形成独立桥面板，将独立桥面板分区为固定区、过渡区和移动区；其中在固定区内的混凝土桥面板与钢梁顶板之间形成强连接，过渡区内的混凝土桥面板与钢梁顶板之间形成弱连接，弱连接指的是，允许混凝土桥面板与钢梁顶板之间发生微小变形的连接；移动区内的混凝土桥面板与钢梁顶板之间形成填充连接，填充连接指的是，允许混凝土桥面板与钢梁顶板之间发生较大水平变形。本发明的优点是：1）可以实现桥面板整片预制，保证工期；2）释放混凝土桥面板顺桥向应力，减少混凝土开裂，减轻后续养护工作；3）桥面板分块施工，施工便捷，对大型机械依赖少。
