Deepening design refers to deepening the design, making the surface of the drawings appear, meeting the design and installation requirements of the connection nodes, and finally making the project smoothly implemented. It includes not only the content of the design, but also the material supply, transportation, installation methods, and sequence that the construction contractor cares about, and partly assumes the role of engineering consulting.
The main content of deepening the design
(1) Simulation analysis of the entire construction process
For a long time, the simulation analysis of the entire construction process has been applied to the construction of steel structures. With the increase of large-scale civil engineering, construction simulation has gradually become an indispensable part of large-scale complex engineering.
(2) Structural design optimization
In the simulation modeling analysis, the original structural design calculation model is the same as the calculation model considering the entire construction process. Although the final state is the same, the stress and deformation caused by the construction support or construction temperature during the construction process. The stress generated by components and nodes during construction will not disappear as the structural geometry returns to the design stage, and is usually local. The structure is kept separately, which affects the safety of the structure during its service life.
(3) Node deepening
The connection joints of ordinary steel structure mainly include column foot joints, support joints, beam-column joints, beam-beam joints, truss chord web joints, bolt ball joints, welded spherical joints, steel pipe intersection joints, multi-member intersection cast steel joints, and pre Stressed steel structures include diagonal joints, tension joints, diagonal pull-through joints, etc. The design of the above-mentioned various joints belongs to the scope of construction drawings. The main content of the node deepening is to check the unspecified nodes in the drawing by welding strength, bolt group, on-site node connection calculation, node design feasibility check, complex node space lofting, etc. according to the construction drawing design principles.
(4) Component installation drawings
The installation drawings are used to guide the on-site installation positioning and connection. After the components are processed, the main task of the installation diagram is to install each component in the correct location and connect it in the correct way.
(5) Parts processing drawings
Part processing drawings are factory drawings, the basis for factory processing, and the basis for parts acceptance. Parts processing drawings can be divided into parts drawings and parts drawings.
With the development of CNC machine tools and related control software, parts drawings are gradually replaced by computer automatic lofting. At present, cross-line cutting has basically realized paperless production and ordinary steel structure production. The domestic advanced processing enterprises have gradually developed towards computer automatic cutting, cutting and processing.
(6) Quantity analysis
It is easy to ignore the material table in the parts drawing. But it is an important part of the depth detailed drawing, it contains the number of parts, parts, bolts, and the corresponding specifications, quantity, size, weight and material information, which is very helpful for the correct understanding of the drawings, and can be easily Get the accurate information you need for purchasing. By summarizing and classifying these material tables, you can quickly formulate material procurement plans and installation plans, providing great convenience for project management.
The above is the summary of the required materials for the quality inspection of the steel structure workshop. If you have any questions, you can contact the customer service of Modi Steel Structure Engineering Co., Ltd. for consultation, and will continue to update more steel structure knowledge and common sense.
