How to avoid the hidden danger of steel structure?
Grid steel structure is mainly made of steel, mainly composed of steel beams, steel columns, steel trusses and other components made
of section steel and steel plate, which are usually connected by welds, bolts or rivets. It is one of the main types of building structures.
A. Fire is a problem for all buildings. The fire resistance of steel grid is still a problem. However, when the temperature is too high,
the steel will melt. The rigidity, elasticity and other properties of the steel will drop sharply here, and the bearing capacity will be lost.
To avoid such a problem, the first is to eliminate the fire hazards in the building, and then to carry out anti-corrosion and fire
prevention treatment on the grid structure, which can effectively extend the fire resistance time and allow time for fire rescue.
B. Compared with the concrete structure, the stability of the grid steel structure is slightly worse, but its construction time is relatively
fast, which is easier to achieve for long-span buildings than concrete.
C. Corrosion, because the grid structure is of metal texture, but also under ultraviolet light for a long time, if the geographical
environment of the grid construction is worse, then the rust, corrosion and other conditions will be more serious. In such a case,
the anti-corrosion work should be done well at the beginning of grid construction, and after the anti-corrosion work is done well
in the early stage, the grid structure should be inspected every six months, and then the anti-corrosion maintenance work should be
done, which is the important way to completely avoid the grid corrosion accident.
