The invention discloses a positioning device and a positioning method for a spatial special-shaped curved surface steel structure, the positioning device comprises a plurality of supporting columns mounted on the ground, each supporting column is provided with a hub node, a rectangular pipe is connected between every two adjacent hub nodes to form a jig frame structure, the hub nodes are mounted on the supporting columns through positioning pipes, and the positioning pipes are connected with the hub nodes. The positioning pipes are provided with inclined sections so that the hub joints can be in an inclined state, and all the positioning pipes are provided with positioning notches in the first direction. The direction positioning of the inclined section of the arc-shaped structure on the positioning pipe is changed into positioning of the positioning notch in the positioning pipe, and after the positioning notch of the positioning pipe is machined according to the target direction, a constructor can conveniently install the positioning notch of the positioning pipe towards the target direction in a unified mode when installing the positioning joint. The construction efficiency of the spatial special-shaped curved surface steel structure is greatly improved, and meanwhile the positioning accuracy can be guaranteed.

本发明公开了一种空间异型曲面钢结构的定位装置及定位方法，该定位装置包括多个安装在地面上的支柱，每个支柱上均安装有毂节点，相邻两个毂节点之间连接有矩形管，以形成胎架结构，毂节点通过定位管安装在支柱上，定位管上具有倾斜切面，以供毂节点呈倾斜状态，全部定位管上均沿第一方向开设有定位切口。本发明将需要对定位管上圆弧形结构的倾斜切面进行方向定位转变为对定位管上的定位切口进行定位，按照目标方向加工出定位管的定位切口后，便于施工人员在安装定位节点时将定位管的定位切口朝向目标方向统一安装即可，大幅提高空间异型曲面钢结构的施工效率，同时也能够保证定位的准确性。
