Hainan Steel News: Steel housing pressure plate concrete composite floor system


Floor 1.5 hours due to meet fire request, which shall be poured on 80 thick concrete, using disc-pressing plate slab thickness will reach 130 ~ 150mm, and when used in residential construction, interior subject to the ceiling, such as the use of fresh buckle type of pressure plate slab thickness can be reduced to 110mm, steel housing can be used for the BD-40 type baraeck fresh button pressure plate, which rib height of only 40mm, and the mouth closed, do not need to do the ceiling, only bandages need to be affixed in the crevice. Since the composite slab bears a horizontal force transfer effect, and therefore the pressure plate girder connections should set the necessary pegs, consider the design of steel beams and floor combined effect, can significantly improve the bearing capacity and stability of the beam, effective reduce the high beam. Usually a combination of the lower part of the floor without additional reinforcement, but there are dynamic loads and relatively humid area, the lower floor still needs to cultivate the necessary structural reinforcement. But the combination of floor should meet weighted standardized impact sound pressure level of less than 75dB of request. Abroad, floor insulation request has become increasingly important in residential design. Hainan Steel
