Nose bridge for assisting steel beam erection and construction method
The nose bridge comprises a vertical rib, a main longitudinal beam and an inclined strut, one end of the main longitudinal beam is a connecting end, the other end of the main longitudinal beam is a temporary supporting end, the connecting end is fixedly connected to the bottom end of one side of the vertical rib, the high end of the inclined strut is installed on the top of the vertical rib, and the low end of the inclined strut is installed on the main longitudinal beam; and a connecting structure connected with the side surface of the steel beam is arranged on the side surface of the vertical rib adjacent to the mounting side of the main longitudinal beam. According to the method, when the steel beams are erected, the steel beams are erected in a full-cantilever mode through the beam erecting crane, an incremental launching method is not adopted for construction, temporary piers are not needed, materials and equipment are saved, waiting for completion of temporary pier construction is not needed, the construction period is relatively short, and the rapid construction requirement is met.
本发明提供了一种辅助钢梁架设的鼻梁，包括竖肋、主纵梁和斜撑，所述主纵梁一端为连接端，另一端为临时支撑端，所述连接端连接固定于竖肋一侧底端，所述斜撑高端安装于竖肋顶部，斜撑的低端安装于主纵梁上；所述竖肋在其紧邻主纵梁安装侧的侧面设有和钢梁侧面连接用连接结构。本发明中，钢梁架设时采用架梁吊机全悬臂架设钢梁，不采用顶推法施工，不需要临时墩，节省材料、设备，不需等待临时墩施工完成，施工周期相对较短，符合快速施工要求。
