What are the requirements of combination fire floor boards ?
Update time：2014-07-07 15:57:00 times：3196times
General Provisions
1, fire resistance combination floor boards should be consistent with the current national standard "architectural design code for fire protection} GB50016 requirements and other standards on the floor;
2, floor boards as a non-permanent template uses a combination of floor, the fire-resistant design of reinforced concrete slabs should be fire-resistant design method.
3, floor boards rely on a combination of positive reinforcement or rebar bending zone of the lower chord truss composite slabs from resisting the effects of its reinforced protective layer thickness [excluding the bottom die thickness) should meet the appropriate requirements for fire resistance according to the member function.
4, fire resistance without fire protection can be a combination of floor boards of fire test methods or calculations OK.
Floor plate paint when painting fire protection association standards should be consistent with the current "fireproof coatings application requirements CECS24 of technical specifications}.
When the fire resistance of composite slabs 5 calculation, use the following assumptions:
⑴ not considered when heated floor slab bearing effect on the binding effect within the plane (axial force).
⑵ does not consider the impact of the pressure plate when the bearing capacity of the floor heating;
⑶ assume that the floor temperature with depth from considering only backfire on the surface;
⑷ not consider shear bond ultimate limit state;
In addition to the floor by the force.
⑸ reinforcement, the floor of the structural steel, steel may be used as a temperature cracking force barium tendons.
