In addition to qualified materials and high manufacturing accuracy, the quality of steel structure engineering also depends on reasonable installation technology. At present, the installation methods of steel structure mainly include: mechanical installation, soil method installation, soil machine combination installation, jacking installation, lifting installation and sliding installation. Steel structures have different requirements for different structures from material procurement, production, installation to finished products,As far as the installation method is concerned, the best installation technology and hoisting method are formulated according to the factors of good engineering quality, safe production, guaranteed construction period, low cost and civilized construction, combined with the different characteristics of various projects.

(1) During loading and unloading and transportation, the components shall be protected as far as possible to avoid damage during transportation.

(2) For some minor components such as purlins, braces, corner braces, etc., due to their small stiffness and large quantity, they should be packed in the transportation process, and it is strictly forbidden to bulk them, resulting in confusion in shipment.

(3) The transported components must be delivered according to the hoisting requirements and procedures, and the supporting supply should be considered as far as possible to ensure the smooth hoisting on site.

 (4) the components shall be placed symmetrically on the transport vehicle, and the loading and unloading of the vehicle shall be operated symmetrically to ensure the fixation of the body and the components on the vehicle.

(5) Secondary components and main components shall be loaded and transported together, and heavy components shall not be stacked on the secondary components to cause compression deformation of components.(6) In the process of component transportation, cushion wood should be placed. When fixing with steel wire rope, the four corners of the component should be protected to prevent the component from deformation and cutting off the steel wire rope. For unstable components, support should be used to stabilize.
