Large-span dome jig frame form switching construction method
The invention discloses a form switching construction method for a large-span dome jig frame, which relates to the field of steel structure engineering building construction and comprises the following steps: data confirmation: determining jig frame use requirements; measuring and setting out, and positioning the span radius and elevation of the jig frame; performing form switching construction on the dome assembling jig frame, namely releasing constraint at the upper end of a beam string structure, hoisting the beam string structure, and lowering the beam string structure to a bracket of a central inner cylinder; the height of the center inner cylinder is adjusted to reach the specified elevation; releasing constraint at two ends of the beam string structure, connecting the upper end of the beam string structure with the upper triangle of the central inner cylinder, and putting the lower end on a temporary scaffold; after all beam string structures are adjusted section by section, the whole circle of lower triangles are moved to the located jig frame span radius position; and connecting the lower end of the beam string structure through a traction device, so that the lower end of the beam string structure is connected with the lower triangle until the construction of all residual beam string structures is completed. Therefore, the purposes that the jig frame is suitable for large-span construction engineering, the jig frame mounting procedure is shortened, and the mounting precision is guaranteed are achieved.
本发明公开了一种大跨径穹顶胎架形态切换施工方法，涉及钢结构工程建造施工领域，包括以下步骤：数据确认，确定胎架使用需求；测量放线，定位胎架跨度半径与标高；对穹顶拼装胎架进行形态切换施工：解除张弦梁上端约束，并起吊张弦梁，下放至中心内筒的牛腿上；调整中心内筒高度，并达到指定标高；解除张弦梁两端约束，使张弦梁上端和中心内筒的上三角连接，下端搭放在临时脚手架上；待所有张弦梁逐段调整完毕后，将整圈下三角移动到定位的胎架跨度半径位置处；通过牵引装置连接张弦梁下端，使张弦梁下端和下三角连接，直至完成剩余所有张弦梁的施工。以此达到胎架适用较大跨度施工工程、缩短胎架安装工序、保证安装精度的目的。
