Arthur Vierendeel, born in Leuven, Belgium, is a university professor and civil engineer. The vierendeel structure he developed is named after him. Therefore, the scientific name of the hollow truss is also called Vierendeel truss.
The axis size of the space frame shed for coal storage yard is 120m (1-16 axis) * 300m (A-Q1 axis), and the height is 45.2m.
Taking (Indonesia) Boya 2 × 660 MW pithead power station supporting coal storage yard dry coal shed space frame project installation as an example, this paper focuses on the hoisting new technology and new method of the more dangerous space frame project, and the hoisting wire rope is carried out. The safety force check calculation is carried out, and effective analysis and verification are carried out for the structural hoisting under different working conditions at each stage. The hoisting process mainly includes the beginning of the space frame installation, the use of 50 t crawler cranes and 25 t truck cranes to cooperate with the space frame to continue to extend across the bucket turbine, the support is in place, the support position space frame expansion installation and subsequent space frame installation and other key processes .
Protection of finished products after space frame processing
The welding deformation directly affects the installation and function of steel members and steel structures, and because of the additional bending moment, secondary stress and so on, which indirectly affect the service performance of steel structure engineering, so the control of welding deformation is very important.
