Construction method of rigid-flexible parallel large-span structure
The invention belongs to the technical field of building construction, and discloses a rigid-flexible parallel large-span structure construction method, which is characterized in that the deformation difference of a truss structure is compensated to enable the truss structure to be matched with a zero stress form after high-altitude installation and to be matched with a design form theoretically after all additional structures are installed. And the configuration of the connection assembly is finely adjusted in the horizontal and vertical directions, so that the rigid-flexible parallel structure reaches the design form, and the deformation difference of the rigid-flexible parallel structure is controlled. The first tensioning unit and the second tensioning unit are matched to complete tensioning of the cable set, simultaneous in-place of the cable shapes of all the inhaul cables can be achieved, and it is guaranteed that the cable shapes of all the inhaul cables in the cable set are consistent. The anti-toppling device is connected between the connecting assembly and the cable set, the eccentric bending moment on the cable set can be balanced, and deflection and deformation of the cable set are avoided. The first position fine adjustment device can adjust the position of the enclosure system, the overall flush degree of the strip-shaped structure is ensured, the TMD can be adjusted to reach the ideal quality through the mass adjuster, and the vibration reduction performance of the TMD is ensured.
本发明属于建筑施工技术领域，公开一种刚柔并联的大跨度结构施工方法，通过补偿桁架结构的变形差使桁架结构在高空安装后吻合零应力形态，在全部附加结构安装完成后理论上吻合设计形态，为弥补理论和实际的差异，在水平和竖直方向精调联系组件的位形，使刚柔并联结构达到设计形态，控制刚柔并联结构的形变差。通过第一张拉单元和第二张拉单元配合完成索组张拉，可实现全部拉索索形的同时到位，保证索组内各拉索的索形一致。防倾装置连接于联系组件与索组之间，能平衡索组上的偏心弯矩，避免索组偏转变形。第一位置精调装置能够调节围护系统的位置，确保带状结构整体的平齐度，通过质量调节器可调节TMD达到理想质量，保证TMD的降振性能。
