Construction method for prefabricating and installing large-area thin-wall steel truss girder deck slab
The invention discloses a construction method for prefabricating and installing a large-area thin-wall steel truss girder deck slab. The construction method comprises the following steps of firstly, prefabricating the bridge deck slab; 2, processing a bridge deck slab transport vehicle; 3, installing rubber strips and epoxy mortar at the steel-concrete combination position; 4, positioning and installing the bridge deck; 5, ensuring that a flat slab transport vehicle is hoisted in place; 6, installing remaining bridge deck slabs; 7, after all joints of the bridge deck slab are installed, rechecking the axis and the elevation again, and starting wet joints to be constructed after the axes and the elevation are checked and accepted to be qualified; and 8, conducting inspection and acceptance of overall construction, the invention that the bridge deck slab is transported in place through an on-beam flat slab transport vehicle is adopted, the danger that the large-area thin-wall bridge deck slab is broken in the moving process on the beam is effectively prevented, and meanwhile the situation that the bridge deck slab and a steel truss beam rod piece are damaged due to the fact that the large-area thin-wall bridge deck slab collides with the steel truss beam is avoided.
本发明公开了一种大面积薄壁钢桁梁桥面板预制安装施工工法，包括以下步骤：第一步：首先进行桥面板预制；第二步：进行桥面板运输车的加工；第三步：进行钢砼结合处橡胶条及环氧砂浆安装；第四步：对桥面板进行定位安装；第五步：保证平板运输车吊装就位；第六步：对剩余的桥面板进行安装；第七步：桥面板各节点安装完成后，对轴线及高程进行再次复核，复核验收合格后开始施工湿接缝；第八步：进行整体施工的检查验收，采用梁上平板运输车运输桥面板就位的方法，有效的防止了大面积薄壁桥面板在梁上移动过程中发生折断的危险，同时也避免了与钢桁梁发生碰撞使桥面板和钢桁梁杆件产生碰伤。
