Definition of Steel Structure
Steel structure is a structure composed of steel materials and is one of the main building structure types. The structure is mainly composed of steel beams, steel columns, steel trusses and other components made of section steel and steel plates, and adopts silanization, pure manganese phosphating, washing and drying, galvanizing and other rust prevention processes. The components or components are usually connected by welds, bolts or rivets. Because of its light weight and simple construction, it is widely used in large factories, venues, super high-rise buildings, Bridges and other fields.
What are advantages of Steel Structure?
The material has high strength and light weight
Compared with concrete and wood, the ratio of density and yield strength is relatively low, so under the same stress conditions, the steel structure has small section, light weight, easy transportation and installation, and is suitable for the structure with large span, high height and heavy load.
High degree of mechanization
Steel structure components are easy to be manufactured in the factory and assembled on the site. The factory mechanized manufacturing of steel structure components has high precision, high production efficiency, fast site assembly speed and short construction period.
High structural reliability
It is suitable for bearing impact and dynamic loads and has good seismic performance. The internal structure of steel is uniform, which is close to isotropic uniform body.
Environmental protection
During construction, the amount of sand, stone and ash can be greatly reduced, and the damage to non-renewable resources can be reduced. When the service of the building expires and needs to be dismantled, the steel can be fully recycled, greatly reducing the gray construction waste
Rapid construction
The construction time of steel structure is much less than that of traditional concrete structure
Good sealing performance
Because the welded structure can be completely sealed, it can be made into high pressure vessels with good air tightness and water tightness, large oil pools, pressure pipelines, etc
Types of steel structure
Laminated steel structure
As the main load-bearing beam, the section steel connects the main wall or the support points at both ends of the beam. The main structure should be laid on the pressed steel plate, and then laid steel bars, and the original structure surrounding the planting bar connection, and finally poured concrete.
Villa extension steel structure
The main structural beam, column and shelf support of the steel structure villa are composed of cold-formed thin-wall steel structure or composite beams. The steel structure components are light in weight, easy to transport, install, and easy to install and disassemble and expand.
Tower steel structure
The tower belongs to the high-rise steel structure, and the main structural material is steel pipe. The tower is widely used, and can be used for factory chimney support, large building support, water tower tower, monitoring engineering, communication engineering and other special purposes.
Stair steel structure
The supporting system of the steel structure staircase is the steel inclined beam as the main structural component, and the ladder section is mainly composed of steel plate pedals. The form of the balustrade is mostly in the form of diagonal lines of the diagonal beams of parallel stairs. It is characterized by small area, convenient construction, random shape and strong practicability.
Roofing system
It is composed of roof truss, structural OSB panel, waterproof layer, light roof tile and related connecting parts. The appearance of the roof of the light steel structure of Matt Building can be combined in a variety of ways. Under the premise of ensuring the waterproof technology, there are many options for the appearance.
Wall structure
The wall of light steel structure house is mainly composed of wall frame column, wall top beam, wall bottom beam, wall support, wall panel and connecting parts. Building a light steel structure of the house generally use the inner transverse wall as the load-bearing wall of the structure, the wall column is a C-type light steel member, the wall thickness is determined according to the load size. The wall structure layout of light steel structure residential buildings can effectively bear and reliably transfer vertical loads, and the layout is convenient.
Prefabricate and assemble steel components on the steel platform according to the installation sequence and process requirements, ensuring the quality of welding production.The spacing between the joint of the flange plate and the joint of the web plate of the section steel should be greater than 200mm. The splicing length of the flange plate should not be less than twice the plate width; The width of the belly plate splicing should not be less than 300mm, and the length should not be less than 600mm.
For the convenience of welding and to ensure welding quality, the reinforcement plates, connecting plates, cushion plates, and cantilever beams on the columns and beams should be assembled and welded on the ground steel platform according to the construction drawing dimensions as much as possible.
The prefabricated steel components on the steel platform should not only be manufactured and assembled according to the construction drawings and specifications, but also consider the process of on-site installation and changes in installation dimensions.
Reinforcement of steel structure
Section reinforcement method
Steel reinforcement is used locally or along the entire length of the component, connecting it into a whole to jointly bear the force
Change the calculation diagram
Adding additional supports, adjusting load distribution, reducing internal force levels, forcing displacement of supports for statically indeterminate structures, and reducing stress peaks
Prestressed cable method
Using high-strength cables to reinforce weak links in the structure or improve the overall bearing capacity, stiffness, and stability of the structure.
