Installation construction method for quickly erecting steel frame bridge
The invention provides a mounting construction method for quickly erecting a steel frame bridge, and relates to the technical field of bridge engineering. According to the installation construction method for quickly erecting the steel frame bridge, a truss frame is included, a plurality of inclined struts are fixedly connected into the truss frame, a plurality of beret pieces are connected into the top end and the bottom end of the truss frame through truss pins, and reinforcing chord members are connected to the top end and the bottom end of the truss frame through bolts. A plurality of cross beams are arranged on the lower portion of the inner side of the truss frame, a wind-resistant pull rod is arranged at the bottom end of the truss frame, a plurality of bridge deck slabs are arranged at the top ends of the cross beams at equal intervals, and a male head end column is fixedly connected to the rear end of the truss frame. The cantilever push-out method is used for splicing construction, the situation that the push-out method cannot be directly adopted for construction of the bridge due to the fact that topographic conditions of high mountains and canyons are restrained and limited is avoided, the construction period is made to be in the normal level, and the actual delivery time of the steel frame bridge is guaranteed.
本发明提供一种快速架设钢架桥安装施工方法，涉及桥梁工程技术领域。该快速架设钢架桥安装施工方法，包括桁梁架，所述桁梁架的内部均固定连接有若干个斜撑，所述桁梁架的顶底端内部均通过桁架销连接有若干个贝雷片，所述桁梁架的顶底端均通过螺栓连接有加强弦杆，所述桁梁架的内侧下部设置有若干个横梁，所述桁梁架的底端设置有抗风拉杆，所述横梁的顶端等距设置有若干个桥面板，所述桁梁架的后端固定连接有阳头端柱。通过使用“悬臂推出法”拼装施工，避免了高山峡谷的地形条件制约和限制，导致桥梁的建设无法直接采用推出法进行施工的局面，使施工工期处于正常水平，保障钢架桥桥梁的实际交付时间。
