Q:What are the protective coatings for steel structures? Do they need to be tested and sampled?
The main protective coatings for steel structure are protective primer, intermediate paint, finish coat and fireproof coating for steel structure. Mainly primer, fire retardant paintIn testing, primer, intermediate paint, finish coat and fireproof coating are required before entering. After construction, fire retardant coatings for steel structures need to be tested on-site (compulsory). Some protective paint also need on-site inspection (see supervision or design, etc.).Sampling should be representative and stir well. Take the amount of each test unit requires different paint class probably take 500-1000ml can. Fire retardant paint, if it is a thick powder, take at least 1500g. In general, we should take more, because the inspection unit to retain part of the original.Sampling and testing are witnessed and non - witnesses, it is best to notify the supervisor to the scene.
Q:The steel structure housing about how much money.
If it is a high-rise, it will need to increase the steel beam, then the cost will increase accordingly. Refer to
Q:What does steel structure cross section L75*5 mean?
Steel structure is mainly made of steel material, and it is one of the main types of building 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.
Q:What is the brittle fracture of steel or steel structure?
Brittle fracture of steel or steel structure means a sudden fracture under the nominal stress (tensile strength or yield strength of steel under tensile test). The fracture surface is usually a single and relatively flat, split surface with little or no shear lip.
Q:What plate is the slab below the concrete floor of the steel structure?
In order to meet the requirement of rapid construction of the main steel structure, a firm platform can be provided in a short period of time, and a plurality of floors can be used for laying profiled steel plates, and the concrete flow of the concrete slab is divided into layers.
Q:What does a product frame refer to in a steel structure workshop?
Steel structure workshop refers to the steel column and steel beam on each axis. The steel structure workshop is made up of N pieces, a steel frame including steel columns, steel beams and high-strength bolts for connection.
Q:What is a steel beam?
Homogeneous and isotropic material, an ideal elastic body, the most consistent with the basic assumption of the general engineering mechanics; material has good plasticity and toughness, and can have large deformation, can well withstand dynamic loads; short construction period; the high degree of industrialization, can carry out specialized production of high degree of mechanization; processing high precision, high efficiency, good sealing performance, so it can be used in the construction of tank, tank and transformer etc.. Its disadvantage is poor fire resistance and corrosion resistance. Mainly used in heavy duty workshop bearing frame, dynamic power plant structure, plate and shell structure, high tower and mast structure, bridges and warehouses and other large-span structure, high-rise and super high-rise buildings.
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.
Q:The role of stiffeners in steel structures?
Under the condition of not increasing the wall thickness of the product, the strength and rigidity of the product are enhanced, thereby saving material consumption, reducing weight and reducing cost
Q:What is called steel structure?
The composite structural members of SRC (SRC or SRC) are made up of concrete, shaped steel, longitudinal reinforcement and stirrups. The basic component is Liang Hezhu.The structure of the stiff concrete is divided into all structural members, the structure of the reinforced concrete and the part of the structure, and the structure of the stiff concrete.The stiff concrete has many advantages, such as high strength, small section size of the component, strong binding force with the concrete, saving concrete, increasing the use of space, reducing the cost of the project and improving the quality of the project.
