五、悬掛屋盖屋面的构造及稳定措施屋盖的悬索如何安装才能保证构成计算所要求的曲面,这还是一个需耍进一步研究的问题。通常可以采取三种办法:①用悬索的计算长度控制:即根据计算所得的长度切取一段钢索,两端做成锚固头,安装就位后浇灌于支承构件内。这种做法很难准确,因为支承构件会有施工误差,就使悬索长度有了改变,因而悬索受力情况就会发生变化。但如果采用预应力,则以此法为优。因其误差可在预加应力时碍到调整。
Fifth, the structure of the roof of the roof and stability measures How to install the suspension of the roof to ensure the composition of the required surface of the calculation, this is still a problem that needs further study. Generally, three methods can be used: (1) Controlling the length of cable with a cable: Cut a length of steel cable according to the calculated length, and fix the cable at both ends. After installation, place it in the supporting member. This method is difficult to be accurate, because there will be construction errors in the support members, so that the length of the suspension cable has changed, so the stress of the suspension cable will change. However, if prestress is used, this method is preferred. Because of its error can be adjusted in the pre-stressed.
