Large-span net rack external expansion assembly integral jacking construction method
The invention discloses a large-span net rack external expansion assembly integral jacking construction method, which belongs to the field of building construction. The technical problem to be solvedby the invention is how to reduce the construction difficulty of large-span net rack structures of a spherical shell, a cylindrical shell, a flat plate and various special-shaped stadiums under complex conditions, reduce high-altitude operations, improve safety, and ensure the construction quality. The adopted technical scheme is that the large-span net rack external expansion assembly integral jacking construction method comprises the following steps of: assembly and jacking, that is, the net rack is assembled on the ground, and when the net rack is assembled to a stand position, a jacking bracket is installed, and the jacking work is stopped when the net rack is jacked by using the jacking bracket to a preset height to meet the next grid assembly; symmetrical external expansion assembly,that is, after the jacking work is stopped, symmetrical external expansion assembly is performed on completed space stiffness units from the center of the net rack to make the net rack continue to extend to the surroundings; adjustment of the number and locations of jacking points, that is, when performing expansion assembly outward, the number and positions of the jacking points of the net rackare adjusted according to calculation results; and unloading and dismantling.
本发明公开了一种大跨度网架外扩拼装整体顶升施工方法，属于建筑施工领域，本发明要解决的技术问题为如何减少球壳、筒壳、平板及各种异形场馆类大跨度网架结构复杂条件下的施工难度，减少高工作业，提高安全性的同时确保施工质量，采用的技术方案为：该施工方法具体如下：拼装及顶升：网架在地面进行拼装，拼装到看台位置时安装顶升支架，利用顶升支架把网架顶升设定高度满足下一网格拼装时，停止顶升工作；对称外扩拼装：顶升工作停止后，由网架中心开始对称外扩拼装已完成的空间刚度单元，使网架不断向四周延伸；调整顶升点数量及位置：向外扩展拼接时，根据计算结果对网架顶升点的数量和位置进行调整；卸载及拆除。
