The invention discloses a truss structure dismantling method, and belongs to the technical field of building construction. The method comprises the following steps: a truss structure is dismantled into a plurality of sub-trusses; a tower crane is connected with one ends of the sub-trusses and is used for providing oblique upward pulling force deviating to one sides of the sub-trusses; an auxiliary hoisting device is arranged in a projection area, and the auxiliary hoisting device is connected with the other ends of the sub-trusses and used for providing oblique upward pulling force deviating to the other sides of the sub-trusses; the projection area is an area where an overhanging outer frame is projected on the ground; the tower crane and the auxiliary hoisting device synchronously hoist the sub-trusses to enable the sub-trusses to leave the projection area; and after the sub-trusses leave the projection area, the auxiliary hoisting device stops hoisting, and the tower crane hoists the sub-trusses to the ground. According to the truss structure dismantling method, the hoisting performance of the tower crane can be fully utilized, the dismantling workload is reduced, and the operation efficiency can be improved.

    本申请公开了一种桁架结构拆除方法,属于建筑施工技术领域,该方法其包括以下步骤:将桁架结构拆除为若干子桁架;塔吊连接子桁架一端并用于提供偏向于子桁架一侧的斜向上拉力;在投影区内设置辅助吊运装置,辅助吊运装置连接子桁架另一端并用于提供偏向于子桁架另一侧的斜向上拉力;其中,投影区为悬挑外框在地面投影的区域;塔吊和辅助吊运装置同步将子桁架吊起使子桁架离开投影区;子桁架离开投影区后,辅助吊运装置停止吊运,塔吊将子桁架吊运至地面。本申请的桁架结构拆除方法,其能够充分利用塔吊的吊装性能,减小拆除工作量,有利于提高作业效率。
