Integral hoisting construction method for steel structure grid
The invention discloses an integral hoisting construction method for a steel structure grid. The integral hoisting construction method comprises the steps of construction preparation, laying-out positioning, lower chord ball placement, elevation adjustment of a lower chord ball, lower chord assembly, upper chord and web member assembly, inspection, correction, acceptance inspection, lifting, aerial rod supplementing, acceptance inspection and the like. When the steel grid is assembled, the position coordinates of all the nodes are determined in the form of establishing an accurate square grid, so that the assembly and installation accuracy of the grid structure is increased, and the mode of expanding assembly from the middle to the periphery, assembling on the ground and then integrally lifting is adopted, so that the construction efficiency is improved.
本发明公开了一种钢结构网架整体吊装施工方法，包括施工准备→放线定位→搁置下弦球→调整下弦球标高→组装下弦→组装上弦、腹杆→检查→校正→验收→提升→空中补杆→验收等步骤。本发明的的钢网架拼装时通过建立准确的方格网的形式确定各个节点的位置坐标，提高了网架结构拼装、安装的精准度，采用由中间向四周扩展拼装、地面拼装再整体提升的方式，提高了施工的效率。
