Single-storey steel structure installation construction technology

　　Single-storey structural steel

　　installation is represented by single-storey industrial plant structure installation. Single-storey plants are generally composed of columns, suspension beams, roof racks, skylight racks, purlins, wall racks and various supports. Due to the different forms, sizes, weights and installation elevations of the components, different lifting equipment and lifting methods should be used, and adequate preparations should be made to lay the foundation for the installation works.

　　① Technical preparation

　　Preparation of construction organisation design.

　　Contents include: project overview and characteristics; construction organisation deployment; construction preparation plan; construction procedure and process design; lifting programme; construction schedule; construction site layout plan; supply plan for labour, mechanical equipment, materials and components; quality and safety measures; mode of transport of components, stacking and site management; environmental protection, etc.

　　Steel structure installation should be carefully read and reviewed the relevant drawings and technical documents before installation, and problems found should be contacted with the owner and design unit in time to solve hidden problems.

　　Preparation of steel column foundation and supporting surface: before installation, the strength of the foundation concrete must meet the design requirements.
