Steel structure design drawing stage?

Steel structure design drawing is divided into two stages: steel structure design drawing and steel structure construction detail drawing.

The design drawings of steel structure shall be completed by a design unit with design qualification, and the content and depth of the design drawings shall meet the requirements of drawing up the detailed construction drawings of steel structure; Detailed construction drawings of steel structures (i.e. production drawings) should generally be completed by production units with special design qualification for steel structures, or by other units with such qualification.

Note: If the design contract does not explicitly require the design of the construction details of the steel structure, the content of the steel structure design is only the steel structure design drawings.

Steel structure design drawings

1) design description: design basis, load data, project category, general situation of the project, type and quality grade of steel used (physical, mechanical properties and chemical composition requirements shall be provided when necessary), as well as model, specification, weld quality grade, anti-corrosion and fire prevention measures of connectors; 2) The foundation plan and detailed drawing shall show the detailed drawing of the connection structure between the steel column and the lower concrete member; 3) The structural layout (including floors and roofs) shall indicate the positioning relationship, elevation, position and quantity of components (which can be drawn by single line), node detail index number, etc. When necessary, purlin, wall beam layout and key section drawings shall be drawn; The space grid should draw the upper and lower chords and key sections; 4) Detailed drawings of components and nodes a) Simple steel beams and columns can be represented by unified detailed drawings and tabulation methods, indicating the construction year, type, size, specification, stiffening rib method, detailed drawings of connection nodes and construction and installation requirements of steel. B) For lattice beams, columns and supports, plan and sectional views (plus elevation views if necessary), positioning dimensions, overall dimensions, sub-dimensions and sub-dimensions shall be drawn, indicating the model and specifications of individual components, as well as the connection details of assembly nodes and other components.

Detail drawing of steel structure construction

According to the design drawings of steel structures, enlarged drawings of various parts of structural members, standard detail dimensions, material requirements, machining accuracy, technological process requirements, weld quality grades, etc. , should be numbered; Considering the transportation and installation capacity, determine the segmentation and assembly nodes of components.
