Construction method for assisting steel beam erection by using support legs of beam erection crane
The invention provides a construction method for assisting in erecting a steel beam through a supporting leg of a beam erecting crane. The construction method comprises the following steps that S10, the crane front supporting leg is arranged at the front end of a cantilever of the beam erecting crane; s20, a previous section of steel beam is erected through a beam erecting crane; s30, the beam erecting crane is moved to the previous section of steel beam, the bottom end of a front supporting leg of the crane extends out to be supported on the top of the pier, and a temporary supporting point is formed; and S40, an upper pier section steel beam is erected through a beam erecting crane, the upper pier section steel beam is piled through a pad, the upper pier section steel beam is fixedly connected with the previous section steel beam in the step S20, and steel beam piling is achieved. 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, the dismantling time does not need to be considered, and the rapid construction requirement is met.
本发明提供了一种利用架梁吊机支腿辅助钢梁架设的施工方法，包括以下步骤：S10：在架梁吊机的悬臂的前端设置吊机前支腿；S20：使用架梁吊机架设前一节段钢梁；S30：架梁吊机移至所述前一节段钢梁上，吊机前支腿底端伸出支撑于所述墩顶部，形成临时支点；S40：架梁吊机架设上墩节段钢梁，抄垫使上墩节段钢梁上墩，将其和步骤S20中的前一节段钢梁连接固定，实现钢梁上墩。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，亦不需考虑拆除时间，符合快速施工要求。
