Q:Does the steel structure belong to high-risk industries?
Involving high-risk chemicals (Public Security Bureau), fire control, occupational health, major hazard sources, environmental protection procedures should be handled accordingly, there are three simultaneous reports.
Q:How to calculate the purlin of steel structure.
Single purlin weight =7.5* (0.16+ (0.06+0.02) *2-4*0.0025) *19.625=45.63 kg.You don't have 7.5 meters in the design bill, so you can ask about the design.
Q:What are the types of steel structures
Containers closed, such as large storage tanks, gas reservoir, the furnace shell needs to accept a Chongqing steel structure with a large internal force and rapid temperature change of blast furnace structure, large diameter high pressure pipeline are shell steel structure, there are some large hydraulic lock gate structure and shell structure.
Q:What is a light portal steel frame?
Light steel structure is made of steel (steel plate and shaped steel), and compared with other materials, the steel structure has the following characteristics:High strength steel strength and elastic modulus of concrete, masonry and wood to be many times higher, due to the small weight, high stiffness, steel structure for the construction of large span and super high and super heavy buildings especially suitable for.Small weight - the weight of ordinary steel roof truss only reinforced concrete roof truss 1/4~1/3, if the use of thin-walled steel roof, it is lighter. Because of its light weight, the steel structure is also convenient for transportation and lifting, and can lighten the burden of the substructure and the foundation.Uniform material - the internal structure of the steel is uniform, very close to the isotropic body, and in a certain range of stress, it belongs to the ideal elastic work, and accords with the basic assumption adopted in engineering mechanics. Therefore, the calculation method of steel structure can be accurate and reliable according to the principle of mechanics.
Q:What does steel structure HW stand for?
H is divided into hot-rolled H steel and welded H steel (H) two, hot-rolled H steel is divided into wide flange, H steel (HW), flange H (HM) and narrow flange H (HN) three.
Q:In the steel structure safety margin refers to what?
When the calculations of structural steel to the strength and size of your theory, you have to leave, to increase the size or structure of steel used high performance steel, this is the safety margin, or accident probability, general safety margin will add a lot of, or even several times.
Q:How to consider the influence of base displacement on steel structure
When performing the structural search and acceptance, the steel structure is completed after installation. Often issued axis displacement, the vertical deviation is too large and the height of the column column below the design elevation. In the high-rise steel structure engineering, it is also found that the spacing of each column is too large or too small, and it is often found that the top elevation at both ends of the beam is inconsistent when searching the top of each layer.
Q:What does nonstandard steel structure mean?
Non standard equipment is non standard equipment, non-standard equipment is compared with standard equipment (GB, HG, JB and so on national or industry standards) in terms of not in accordance with the unified national industry standards and specifications for manufacturing equipment, but according to their own need to use their own design and manufacture of the equipment. Equipment whose appearance or performance is not in the catalogue of national equipment products.
Q:What is meant by a steel structure? What's the explanation for the trouble?
The term "limb" in a steel structure is most commonly used in latticed columns, in which the section, section, or plate is commonly referred to as the "limb". Like the limbs of a man, at the periphery.
Q:What effect does the welding slag not have on the steel structure or the reinforced concrete structure?
1, beauty problems. Do not knock off the slag, and the big lump is hard to see on the weld.2. Check welding quality. Don't knock down the welding slag, there was no way of knowing if there is a problem with slag, weld porosity, etc.. And you know, welding can not be formed at once, and it is easy to leak welding.
