Design method of tree-shaped column and modular roof connecting system

The invention discloses a design method of a tree-shaped column and modular roof connecting system. The design method comprises the following steps that 1, internal force and construction deviation of the connecting position of a modular roof and a tree-shaped column are extracted; 2, determining related size and quantity data of the end plate; 3, the size of an angle adjusting device is determined; 4, the boundary dimension and the number of height adjusting devices are determined; 5, determining the number of bolts of the telescopic device in the column and the length of an elliptical hole; 6, checking the bearing capacity of the end plate bolt; 7, checking the bearing capacity of the angle adjusting device; 8, checking the bearing capacity of the height adjusting device; step 9, checking whether the allowable error of the telescopic device in the column is within the allowable range or not; and step 10, checking whether the allowable error of the column end connecting device is within the allowable range o
