Steel-concrete composite beam bridge construction method
The invention provides a steel-concrete composite beam bridge construction method which comprises the following steps that (1) permanent supports are arranged on the tops of piers on the two end sides of a steel-concrete composite beam bridge, and a permanent support and a temporary support are arranged on the top of a pier in the middle of the steel-concrete composite beam bridge; (2) steel beams are correspondingly erected on the permanent supports and the temporary supports; (3) correspondingly paving the concrete bridge deck on the top of the steel beam, and reserving an operation area at the corresponding position of the top of the middle pier; (4) cutting off the steel beam in the operation area; (5) the cut steel beams are sequentially connected, and the adjacent concrete bridge deck slabs are sequentially connected; (6) dismantling the temporary support; and (7) pavement construction is conducted on the concrete bridge deck, and guardrails are installed. According to the steel-concrete composite beam bridge construction method provided by the invention, the concrete bridge deck slab can be prevented from cracking, and the steel consumption and the welding difficulty of the steel beams are reduced.
本申请提供了一种钢混组合梁桥施工方法，包括以下步骤：（1）在钢混组合梁桥两端侧的桥墩顶部设置永久支座，在钢混组合梁桥中部的桥墩顶部设置永久支座和临时支座；（2）将钢梁对应架设在永久支座和临时支座上；（3）将混凝土桥面板对应铺装于钢梁顶部，且于中部的桥墩顶部对应位置处预留作业区域；（4）切断作业区域内的钢梁；（5）将切断后的钢梁依次连接，并将相邻的混凝土桥面板依次连接；（6）拆除临时支座；（7）在混凝土桥面板上进行铺装施工，并安装护栏。本申请提供的钢混组合梁桥施工方法，不仅能够防止混凝土桥面板开裂，而且降低了钢梁的用钢量与焊接难度。
