It depends on the length of the pick, if L is less than 1200, gluten with 3 strips of 18, bottom gluten with 2 strips of 16, greater than 1200 to 1600 with 3 strips of 20, bottom gluten with 2 strips of 18
1. The cantilever reinforcement is the upper reinforcement (the upper part of the steel bar protective layer is thin and the lower part is thick), the floor slab is reinforced at the bottom (contrary to the cantilever layer), and the floor slab is the above. >>>More
Is it a picker? The thickness of the plate is 120mm, the gluten is made of three-level steel bars, the diameter is 10mm, the spacing is 100mm, and the main reinforcement is anchored into the plate at least 1300mm. The concrete strength grade is C25.
In general, the length of the cantilever plate is not more than meters, which is okay. The reinforcement should be determined according to the load. Generally, the thickness of the plate should be 120mm, the concrete should be C25, and the gluten should be made of three-level steel bars with a diameter of 12mm, and the spacing should be 150mm.
To carry out the overturning calculation, there is no ring beam addition, generally extend into the wall 2-3 times the length of the pick-out.
