Splicing method for large-span hyperbolic variable-diameter inverted triangular pipe truss
The invention belongs to the technical field of building steel structures and provides a large-span hyperbolic curve variable-diameter inverted triangular pipe truss splicing method which combines the characteristics of a large-span hyperbolic curve arc variable-diameter inverted triangular pipe truss and is high in splicing precision, easy and convenient to operate, low in cost and high in safety and can rotate by 90 degrees on the ground and lie on the side. According to the method, the hyperbolic curve arc-shaped reducing inverted triangular pipe truss is laterally laid on a jig frame in a segmented mode, vertical projection positioning, ground lofting, segmented splicing and ground assembling of the whole truss are completed, assembling is not affected by the span and the installation height, and the assembling efficiency is improved. The problems that in a conventional splicing method, a full framing needs to be erected, the input manpower and mechanical equipment cost is high, the safety risk coefficient in the splicing process is large, and the splicing precision is difficult to control are solved.
提供一种大跨度双曲线变径倒三角管桁架拼装方法，属于建筑钢结构技术领域，该方法结合大跨度双曲线弧形变径倒三角管桁架特点，研发出拼接精度高、操作简便、成本低、安全性高的地面旋转90°侧躺拼装法，该方法将双曲线弧形变径倒三角管桁架分段侧躺于胎架之上，通过垂直投影定位、在地面放样、分段拼接、整榀桁架地面组对完成，拼装不受跨度、安装高度影响，解决了常规拼装法需要支设满堂架、投入人力及机械设备成本高、拼接过程安全风险系数大，拼接精度难控制的问题。
