Construction method of large-span truss structure connected with flexible structure in parallel
The invention belongs to the technical field of building construction, and discloses a construction method of a large-span truss structure connected with a flexible structure in parallel, a vertical deformation difference delta Z, a horizontal deformation difference delta Y and an axial deformation difference delta X exist between a zero stress form and a design form of the truss structure, and the axial deformation difference delta X is usually neglected due to the fact that the axial deformation difference delta X is small. The vertical deformation difference delta Z of the truss structure is compensated in the factory stage, and the horizontal deformation difference delta Y of the truss structure is compensated in the on-site assembling stage, so that the assembled truss structure is basically matched with the zero stress form. In order to further make up the configuration deviation, the truss structure and the flexible structure are connected through a connection assembly, and the connection assembly comprises a length-adjustable section so as to make up the horizontal coordinate difference of the rigid-flexible parallel structure; a vertical adjustable structure is arranged at the connecting joint of the connecting assembly and the truss structure so as to make up for the vertical coordinate difference. According to the construction method, the deformation difference between the rigid truss structure and the flexible structure can be controlled, and the stress collaboration between rigid and flexible parallel structures is improved.
本发明属于建筑施工技术领域，公开一种与柔性结构并联的大跨度桁架结构施工方法，桁架结构的零应力形态与设计形态存在竖向变形差ΔZ、水平变形差ΔY和轴向变形差ΔX，轴向变形差ΔX由于较小通常予以忽略。在工厂阶段补偿桁架结构的竖向变形差ΔZ，在现场拼装阶段补偿桁架结构的水平变形差ΔY，使得拼装完成的桁架结构基本吻合零应力形态。为进一步弥补位形偏差，通过联系组件连接桁架结构和柔性结构，联系组件包括长度可调段，以弥补刚柔并联结构的水平坐标差异；联系组件与桁架结构的连接节点处设置有竖向可调结构，以弥补竖向坐标差异。该施工方法能够控制刚性的桁架结构与柔性结构之间的形变差，改善刚柔并联结构之间的受力协同性。
