Large-span arched roof structure and enclosure system integrated sliding construction method
The invention discloses a large-span arched roof structure and enclosure system integrated sliding construction method, which comprises the following steps: by using an arch foot of a large-span arched structure as a sliding point, firstly, determining the range of the sliding structure and the size of each sliding unit according to the structural characteristics of a project roof; secondly, the sliding construction process is simulated through computer finite element analysis, the change condition of the horizontal thrust of the arched roof under the construction condition that only arch feet on the two sides are used for sliding is obtained, and then the horizontal thrust of an arch is counteracted in the mode that a rigid constraint type sliding rail is arranged or an active controllable inhaul cable is arranged in a pulling mode. The horizontal thrust of the arch is counteracted by pulling the active controllable inhaul cables or arranging the rigid constraint type sliding rails, a large amount of measure investment for arranging common rails in the midspan is avoided, and the economical efficiency of construction is improved; and meanwhile, the arch is always kept in a design posture through a temporary constraint measure, and integrated construction of the structure and an enclosure system is achieved under the condition that follow-up deformation is very small.
本发明公开了一种大跨拱形屋盖的结构和围护系统一体化滑移施工方法，利用大跨拱形结构的拱脚作为滑移点，首先根据项目屋盖结构特征，确定滑移结构范围和每次滑移单元的大小，其次通过计算机有限元分析模拟滑移施工过程获得拱形屋盖在仅利用两侧拱脚进行滑移的施工条件下水平推力的变化情况，然后采取设置刚性约束型滑轨或者拉设主动可控拉索的方式抵消拱的水平推力。本发明通过拉设主动可控拉索或者设置刚性约束型滑轨的方式抵消拱的水平推力，避免在跨中设置通常轨道的大量措施投入，提高了施工的经济性；同时通过临时约束措施使得拱始终保持设计姿态，在后续变形很小的条件下实现结构和围护系统的一体化施工。
