Bolt ball welding ball mixed node large span cantilever grid structure construction method
The invention provides a bolt ball welding ball mixed node large span cantilever grid structure construction method. The method comprises the steps that 1 a bolt ball welding ball mixed node space grid cell, namely the size and structure of a middle-size cell grid are determined according to the design; 2 a ground assembly moulding bed is arranged; 3 ground assembling is conducted on the middle-size cell grid; 4 coating and numbering are conducted on the middle-size cell grid; 5 a lifting point of the middle-size cell grid is determined and support profile steel is added; 6 a steel wire rope used for lifting and a chain block are arranged, and trying of lifting is conducted; 7 the middle-size cell grid is lifted and installed. The construction period can be greatly shortened, the using amount of construction revolving materials is reduced, the construction efficiency is improved, the safe hidden trouble brought by high altitude construction of constructors can be reduced at the same time, and meanwhile the special requirements on loading, span, forms and the like of a large-scale building grid structure can be met conveniently.
