Light steel structure is a new structure developed on the basis of common steel structure, including all steel structures used under light roof.
Compared with ordinary steel structure, it has better economic index. Jiangsu steel structure light steel structure not only has light weight, low steel consumption, fast construction speed, but also has strong seismic capacity, which can improve the comprehensive seismic performance of the whole building. At present, it is a structure widely used in industrial buildings.
It is not difficult to master the principle of good-looking drawings. In fact, it is very simple, much simpler than the construction of buildings, because he has detailed drawings in each part, and where he does not know, Jiangsu steel structure depends on whether there are any drawings. The detailed drawing symbols in the map, if any, I can see that the place is not a detailed drawing. When I come up with a pair of original drawings, I can understand what a pillar is and what a crossbeam is.
1. Steel structure design drawing can be divided into two stages: steel structure design drawing and steel structure construction drawing.
2. The steel structure design drawing shall be completed by the design unit with design qualification, and the content and depth of Jiangsu steel structure design drawing shall meet the requirements of preparing steel structure construction drawing; steel structure construction drawing (i.e. processing drawing) shall be completed by processing and manufacturing unit with special steel structure design qualification or other units with such qualification.
If the design contract does not specify the design requirements of steel structure construction details, the steel structure design content is only the steel structure design drawing.
3 steel structure design drawing
1) Design Description: design basis, load data, project category, project overview, steel grade and quality grade (physical, mechanical and chemical composition requirements shall be proposed if necessary) and type, specification, weld quality grade, fire protection measures for anti-corrosion connector;
Steel structure: by steel plate, section steel, cold-formed thin-walled steel, etc. through welding or bolt connection.
Features of steel structure: light weight, high strength; good plasticity and toughness; isotropic steel structure in Jiangsu Province, stable performance; weldability is not easy to leak; heat resistance but not fireproof; poor corrosion resistance; easy to manufacture and short construction period.
Plasticity: the ability of a material to absorb deformation energy under static loading. Good plasticity generally does not cause sudden structural fracture due to accidental overload, thus providing safety for people.
3. Connecting plate: the shear strength of the mesh part at the weakened bolt hole must be checked. Jiangsu steel structure http://lasfinanzascambian.com/ The thickness of the connecting plate can be simply regarded as the thickness of the web of the beam plus the thickness of the beam 4mm Except for short beams or beams with large concentrated loads, it is not usually necessary to check the shear strength. In fact, this east is where the steel plate is added to the top of the two butt weldments (usually)
4. Beam web: the net section shear strength of the web at the bolt hole shall be checked. The local pressure of the hole wall of the closed type high strength bolt connection should also be checked.
Changzhou company is engaged in the activities of steel core material, steel plate, steel plate, steel plate, steel plate, steel plate, steel plate, steel plate, steel plate, steel plate, steel plate, steel plate, steel plate, steel plate, steel plate, steel plate, steel plate, steel plate, steel plate, steel plate, steel plate, steel plate, steel plate, steel plate, steel plate, steel plate, steel plate, steel plate, steel plate, steel plate, steel plate, steel plate, steel plate, steel plate, steel plate, steel plate, steel plate, steel plate, steel plate, steel plate, steel plate, steel plate.
In addition, all kinds of construction activities, such as the construction of light-duty buildings and refrigerated buildings, which are approved by the company, can be carried out after the approval of the relevant departments, Jiangsu steel structure Production and installation. Adhering to the principle of customer first, our product design is reasonable and firm; set load-bearing, thermal insulation, waterproof, fire-proof structure, to give its long-term protection.
The company has been strict with quality management for a long time, adhere to the down-to-earth, dare to open up, continuous innovation as the purpose, in strict accordance with the quality management system standards, the pursuit of excellence, adhering to continuous innovation, for environmental protection and energy-saving color steel products and continuous efforts. After years of efforts, the company in Changzhou and neighboring cities have achieved good reputation. This makes a good foundation for building the brand of Longrui steel structural steel activity room. Warmly welcome the new and old customers to come to discuss guidance, sincere cooperation, create brilliant.
