Installation method of double-layer oblique crossing and oblique putting variable-thickness hyperbolic lattice shell structure
The invention relates to an installation method of a double-layer oblique crossing and oblique putting variable-thickness hyperbolic structure and belongs to the technical field of building steel structure construction. The installation method includes the steps that a walking type tower crane is arranged outside the lattice shell structure, and according to load transfer of the walking type towercrane, loads are transferred to a foundation through a rail beam for force application; with the combination of the covering range and the lifting capability of the walking type tower crane, partitioning lifting area and local lifting area ranges of the lattice shell structure are divided; the stress and deformation condition of a lifting point and a lifting process structure is determine; installation and debugging work of the walking type tower crane is conducted according to the determined type and position of the walking type tower crane; partitioning lifting area is spliced according tothe sequence, meanwhile, a combined supporting frame is arranged at the installation position of the partitioning lifting area, overall lifting work begins to be conducted in the local lifting area from the position under the lifting area, and then the local lifting area and the partitioning lifting area are gathered; and finally the lattice shell structure is unloaded. The installation method hasthe beneficial effects that the construction efficiency is high, safety reliability is good, and the construction period is short.
本发明涉及一种双层斜交斜放变厚度双曲网壳结构安装方法，所属建筑钢结构施工技术领域，包括在网壳结构的跨外设置行走式塔吊，行走式塔吊的荷载传递通过轨道梁将荷载传递至基础受力。接着结合行走式塔吊的覆盖范围及起重能力，划分网壳结构的分块吊装区及局部提升区范围。确定提升点及提升过程结构的应力及变形情况。根据已确定的行走式塔吊型号、位置对行走式塔吊进行安装、调试工作。对分块吊装区按顺序进行拼装，同时在分块吊装区的安装位置设置组合式支撑架，以及在提升区正下方开始对局部提升区进行整体提升作业，然后与分块吊装区进行合拢，最后对网壳结构进行卸载。具有施工效率高、安全可靠性好和施工周期短的优点。
