The invention relates to the field of building construction, and aims to solve the problems that in the prior art, steel grid assembly operation is complex, and the quality and the effect of finished products cannot be guaranteed. The invention provides a construction method for a complex curved surface modeling roof grid structure. The construction method comprises the following steps that steel grids are assembled in pieces according to the assembly sequence from far to near, and the steel grids are symmetrically installed; in the hoisting process of the steel girds, the girds are hoisted to a to-be-installed position through a crane, a temporary supporting frame is arranged at the projection position of a gird ball joint in advance, and the temporary supporting frame guarantees that the elevation and the position of a lower welding ball arranged on a supporting frame steel pipe are accurate and free of errors through positioning and paying off of the temporary supporting frame; and rod pieces between any two gird units are connected through welding, and when the ball joints between the grids need to be welded in the step, the adjustable supporting frame is arranged below the ball joints and used for supporting the ball joints. The method has the beneficial effects that the construction is safe, the efficiency is high, and the quality can be guaranteed.
本发明涉及建筑施工领域，旨在解决现有技术中的钢网架拼装操作复杂、成品质量和效果得不到保证的问题，提供复杂曲面造型屋面网架结构施设方法，所述施设方法包括以下步骤：将钢网架进行分榀拼装，拼装顺序为由远及近，对称安装；钢网架吊装过程中，利用吊车吊运网架至拟安装位置，在网架球节点的投影位置提前设置临时支撑架，临时支撑架通过定位放线，保证置于支撑架钢管上的下焊接球的标高和位置准确无误；任意两块网架单元之间的杆件连结通过焊接连结，该步骤中对于需要焊接网架之间的球节点时，在球节点下设置一可调的支撑架，用以支撑球节点。本发明的有益效果是施工安全、效率高且质量能够得到保证。
