Anonymous users2024-01-22If there is no modeling, it is to cut the tendons, the rice minus the protective layer, 130-5 = 125cm = meters, plus the hook 5 2 = 10cm, 125 + 10 = 135 = meter cutting length; This is the basic formula.
Summary. Hello! I'm glad to answer this question, and I've given you the following answer: >>>More
The beam size is unknown, the load is unknown. In general, if the beam of the residential building is 400 high, the gluten of the beam is matched with 2 16, the gluten of the balcony slab extends from the floor surface, and the rest of the steel bars are matched according to the structure.
1. There is no need for double-layer two-way configuration of steel bars, and the thickness of 120mm plate only needs to be matched with the upper stressed steel bar. >>>More
Strictly speaking, this is to be calculated, not only the overhang meter, but also the length and size of the balcony, which directly affects the force of the beam. If you build a house by yourself in the countryside, put four 20 steel bars, stirrups with 8, and the spacing is 150.
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.
