Then calculating methods on construction camber of cast-in-place beam scaffold and setting methods are introduced.

接着介绍了现浇梁支架的施工预拱度计算方法及设置方法。

If the cushion in the main beam, in addition to the main beam camber, the rest of the project can also be checked, but also can check the installation quality of the operating mechanism of the cart.

如是垫在主梁下，则除主梁上拱度一项外，其余项目也都可以检查，同时还可以检查大车运行机构的安装质量。

As a type of special equipment, the construction of large-scale cranes is very difficult, especially the main beam camber control and the deformation control.

这种大型特种设备建造施工难度大，特别是主梁的上拱度控制、大型箱体结构的变形控制都较一般结构难度大。
