Construction method of large-span pipe truss lower chord joints
The invention discloses a construction method of large-span pipe truss lower chord joints. The construction method comprises the following steps: a hanging basket body and two U-shaped hoops are prepared; before one section of a pipe truss is hoisted, the U-shaped hoops are arranged on the pipe truss in a sleeving mode on the ground and are close to a to-be-connected joint of primary and secondary pipe trusses, and the two U-shaped hoops are fixed to the hanging basket body; the section of pipe truss is hoisted, a safety hanging basket is hoisted to the high altitude along with the pipe truss, and the primary and auxiliary pipe trusses corresponding to the joint are connected; after the connection operation of the primary and secondary pipe trusses at the joint is completed, limiting rods are detached, the U-shaped hoops and the hanging basket body are separated, then the U-shaped hoops and the hanging basket body are hoisted to a to-be-connected joint of the next primary and secondary pipe trusses, and then the safety hanging basket is assembled; and the steps are repeated to complete the connection operation of all the primary and secondary pipe truss connection joints. The construction method is easy to operate, and the safety hanging basket can be stably hung on the pipe trusses without shake, so that the working efficiency and the safety are improved.
本发明公开了一种大跨度管桁架下弦节点的施工方法，包括以下步骤：准备挂篮本体和两个U形卡箍；在其中一段管桁架吊装前，在地面上将U形卡箍套设在管桁架上且靠近主次管桁架待连接节点处，两个U形卡箍与挂篮本体固定；吊装该段管桁架，安全挂篮随管桁架吊运至高空中，对该节点处对应的主次管桁架进行连接；完成该节点主次管桁架的连接作业后，拆下限位杆以及将U形卡箍和挂篮本体分离，然后将U形卡箍和挂篮本体吊装至下一主次管桁架待连接节点处，再组装安全挂篮；重复上述步骤以完成所有主次管桁架连接节点的连接作业。该施工方法操作简单，且安全挂篮能稳固地挂在管桁架上，不会发生晃动，从而有利于提高工作效率和安全性。
