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:Is the floor of the steel structure slab cast-in-place or steel?
Steel structure is mainly made of steel material, and it is one of the main types of building structure.
Q:The longitudinal force of a steel column supported by a steel column
Steel structure engineering is mainly made of steel, and it is one of the main types of building structures. The characteristics of the steel is of high strength, light weight, good integral rigidity, deformation ability, it is used in the construction of large span and super high and super heavy buildings especially suitable; homogeneous and isotropic material, an ideal elastic body, the most consistent with the basic assumption of the general engineering mechanics;
Q:Construction technology practice of steel structure in interior decoration
Home improvement, steel structure interlayer construction methods: the main beam using different types of I-beam, general 12cm can. Or to channel steel transverse arrangement of 60--80cm span longitudinal rectangular steel pipe connection, the formation of 400 ~ 600mm Affirmative or rectangular mesh structure to do anti rust treatment.
Q:What are the accessories in the steel structure?
The maintenance system includes: roof and wall inside and outside pressure plate (a single plate project) and thermal insulation layer, and various accessories, standard parts, gutter drainage wall and roof lighting and window part.
Q:Who knows what HW, HN and HM mean in steel structures?
It should be the difference between the elements added to different steels.HW is high tungsten, HN is high nickel, HM is high manganese
Q:What effect does the welding slag not have on the steel structure or the reinforced concrete structure?
Check the pressure leakage test of the pipeline. Water test, if there is a leak point, because the welding slag cover, the exudation of water may not be out of the leak point, is not conducive to check the location of leakage point.
Q:The steel structure and the concrete building which cost is high
The steel structure is of high cost and the steel content per square of the steel structure is higher than that of the concrete structure.
Q:Steel structure workshop column and top beam how to use materials?
The column load is larger, and relatively high age, should choose the lattice column in materials under the same lattice column can increase the section moment of inertia and radius of gyration, improve the stiffness and stability of pillars.
Q:What does "HW350x350" mean in steel structures?
Hot rolled wide flange steel H symbols, web height 350, flange width 350
