随着空间网架结构的发展,螺栓球节点网架以其加工精度高,安装快捷方便,外形美观等特点被广泛采用。同时,在网架制作及安装过程中也常遇到一些质量问题。我们通过有关单位所做的试验,对以下几个问题做了一些分析并提出 With the development of space grid structure, the bolted ball grid frame is widely used due to its high processing precision, quick and convenient installation, beautiful appearance and so on. At the same time, some quality problems are often encountered in the process of making and installing the grid. We have done some experiments by the relevant units, made some analysis on the following issues and put forward
