Q:What is the difference between steel structure HN and HW?
HN is called narrow flange H, which is only H steel with a flange width greater than or equal to 2, mainly used for beams.The use of I-beam is equivalent to that of HN steelWH270*250*18*23 is welded to type H steel. W is the first letter of welding.
Q:What is the performance and function of steel structure engineering?
Resistant to 70 meters per second hurricane, steel structure wind resistance: steel structure construction light weight, high strength, overall rigidity, deformation ability. The weight of the building is only 1/5 of that of the brick concrete structure. Maintain the life and property effectively.
Q:The difference between steel structures
According to the steel: steel columns, steel beams, purlins, tie bar, knee brace, brace, door beam, post, window window column, beam, high strength bolt, bolt, net (rod, ball) and so on.
Q:What is the cushion block in the steel structure?
In the steel structure of wedge type block is used to adjust the steel structure column or large equipment and the top surface of the base pad installed with the steel quantity.
Q:The steel structure housing about how much money.
300 yuan, excluding decorationThe temporary office uses sandwich coloured steel plates.Can find elegant steel structure, such a temporary color board room specializing in the professional company to ask.
Q:What does the construction of steel sub sections mean? What is the difference between a sub branch and a branch? How to divide the sub items?
Divisional Engineering: according to the type or main part of the project, the unit project is divided into sub project. Such as: basic engineering, main project, electrical engineering, ventilation engineering, etc.
Q:Where is the steel structure? High strength bolts?
Steel structure is generally beam column connection, beam and beam connection with high-strength bolts, if the high-rise steel structure building support system should also use high strength bolts
Q:What does steel column support between columns mean?
But at the same time can support for the need to set the compression purlins in local position, is bracing + casing knee bracing frame beam in the end, is often the anti bending moment, is girder tension, flange compression, in order to ensure the stability of frame beam bottom flange, set the knee brace. Horizontal support, in order to ensure that a plane member forms a whole, a support system capable of resisting horizontal forces, is supported by columns, which is equivalent to a horizontal support between columns.
Q:How can the welds in the steel structure be considered qualified?
The weld quality is divided into 3 grades, such as one or two, three, of which the quality grade of the first grade welds is the highest, and so on:Quality requirements for primary welds shall not include defects such as weld, root contraction, undercut and poor joint.There are no defects such as surface porosity, slag inclusion, cracks and arcing defects in the first and two grade welds.The three grade welds can only meet the quality standards of the above two grades with relatively low appearance.
Q:What is the material in the steel structure?
The structure is mainly composed of steel beams and steel plates, such as steel beams, steel columns, steel trusses and so on. Each component or component is usually connected with welds, bolts or rivets. Because of its light weight and simple construction, it is widely used in large factories, stadiums, super high-rise and other fields.
