Method for hoisting and unloading large-span vestibule truss
The invention relates to a hoisting and unloading method for a large-span vestibule truss. The hoisting and unloading method comprises the following specific operation steps that firstly, a temporary support is manufactured and installed; step 2, hoisting the truss; 3, welding and assembling the trusses; and 4, unloading and dismantling the temporary support. According to the technical scheme, segmented hoisting is adopted, and the temporary support is additionally arranged, so that the machine-team, namely, entering and exiting expenses of a large crane are saved, the construction difficulty is reduced, the construction safety coefficient is improved, and large-span vestibule installation can be guaranteed in a limited space; the jacks are additionally arranged on the temporary supports, stable unloading can be achieved after steel structure truss air butt joint is completed, and the construction safety coefficient is increased.
本发明涉及一种大跨度通廊桁架的吊装及卸载方法，具体操作步骤如下：步骤一、临时支架制作安装；步骤二、桁架吊装；步骤三、桁架焊接组对；步骤四、卸载及临时支架拆除。本发明采用分段吊装并加设临时支架的技术方案，节省了大吊车台班即进出场费用，降低施工难度，提高了施工安全系数，在受限空间下可以保证大跨度通廊安装；通过在临时支架处加设千斤顶，可以在钢结构桁架空中对接完成后卸载稳定的卸载，增加施工安全系数。
