1) intercalation interlayer problems referred to here refers to between two natural layer of floor, refers to the local level of building internal space. Selection of steel structure building fire prevention interlining is bound to do the steel structure. Engineering construction quality on site test, the fire resistance of laminated steel column is exactly how to determine, since there is no such standards or unified conclusion.
2) testing standard question many manufacturers of steel structure fire retardant coating type approval certificate is often do not have all of the fire endurance time or refractory limit time for the rest of the time. Fire retardant coating for steel structure engineering construction quality and daily site inspection of fire supervision and brought great difficulties. All kinds of steel members how many thickness of coating to the surface to reach the corresponding fire resistance can't decide fireproof grade rules.
3) testing standards artifacts described the differences with the actual engineering components inspection report of steel beam and steel members in practical engineering is not completely corresponding relation, the actual use of steel members and standards should be how to carry out conversion between steel beam, steel members how to determine the actual use of coating thickness, no provisions of the state. This also brings to the daily supervision and construction quality on site test a lot of problems, in the face of all kinds of steel members, how to determine the fire resistance of its besmear to brush after no standard can depend on.
