Construction method for multiple corridors between large-height-difference buildings
The invention relates to the technical field of building construction, and discloses a construction method for multiple corridors between large-height-difference buildings, which comprises the following steps: determining a main stress layer in each corridor according to the design position of each corridor; the main stress layer and the corridors of all the layers above the main stress layer are assembled in advance, and a corridor assembly body is formed; the corridor assembly bodies are integrally lifted and installed at the design positions corresponding to the corridors; a lower hanging post bracket with the set length is reserved on a truss lower chord of the main stress layer corridor; and components of all layers of corridors below the main stress layer are hoisted in a segmented mode in the mode of retreating from the two sides to the middle, and all the components hoisted in the segmented mode are assembled at the design positions corresponding to all the layers of corridors below the main stress layer. Segmented construction is conducted on the multi-layer corridor through different construction methods, and the situation that the bearing capacity of a basement top plate is insufficient, and consequently the position of a crane is affected is avoided; by reserving the bracket of the lower hanging post, the situation that the lower hanging post cannot be vertically hoisted is avoided, the construction difficulty is reduced, the construction efficiency is improved, and the construction period is shortened.
本发明涉及建筑施工技术领域，公开了一种大高差建筑间多连廊施工方法，包括：根据各连廊的设计位置，确定各连廊中的主受力层；预先拼装主受力层及主受力层上方各层的连廊，形成连廊拼装体；将连廊拼装体整体提升安装在各连廊对应的设计位置；在主受力层连廊的桁架下弦杆预留设定长度的下挂吊柱牛腿；采用从两侧向中间退装的方式分段吊装主受力层下方各层连廊的构件，并在主受力层下方各层连廊对应的设计位置处拼装分段吊装的各构件。本发明采用不同施工方法对多层连廊进行分段施工，避免因地下室顶板承载力不足而影响吊车站位；通过预留下挂吊柱牛腿，避免下挂吊柱无法垂直吊装，降低施工难度，提高建造效率，缩短施工工期。
