Hoisting method for bidirectional bending and twisting dome support

Номер: CN116122579A
Принадлежит:

The invention discloses a hoisting method for a bidirectional bending-twisting dome support, and relates to the technical field of building construction method.The hoisting method for the bidirectional bending-twisting dome support comprises the following steps that firstly, a basement foundation pit is constructed; 2, constructing a steel knot truss; and thirdly, a roof structure is installed, and the second step further comprises the steps that after main body steel structures on the two sides of the truss are installed, a stable frame system is formed, meanwhile, the truss temporary support is installed in place and is inspected to be qualified, and truss rod pieces are hoisted through an on-site tower crane. The truss is segmented by considering factors such as the weight, the distribution position, the tower crane performance and the transportation condition of the truss, in-situ high-altitude splicing is adopted in the truss installation scheme, the component segmentation principle ...
