Cast-in-place with 10 mm reinforcement, a good layer or 8 mm double layer? Why?
If the reinforcement ratio of the situation, the use of 8 mm double reinforced than a layer of 10 mm steel is better, while using the double reinforced cast-in-place floor to prevent from the temperature shrinkage stress is good Oh, can actually try to use reinforced reinforcement ratio is moderate Oh, the only way to ensure the floor the panel does not appear the phenomenon of cracking, especially the roof panel, reinforcement ratio is very important.
The plate near the gable should be equipped with double - layer reinforced wire mesh. Adding radial reinforcement at the corner of the wall. In the region where the temperature and shrinkage stress are greater, a double layer steel mesh should be installed.
Double reinforcement should be adopted for roof bar reinforcement.(5) double deck two-way steel bars shall be installed in cast-in-place slabs with a thickness of more than 120mm.
In general, 8 of the bilayer is better than 10 of the single layer.(1) the reinforcement of cast-in-place slab shall be designed according to the principle of fine reinforcement.(2) the cast-in-place slab shall be controlled with a minimum reinforcement ratio greater than 0.25%.
