The specification requirements for the length of the steel bar binding overlap shall not be less than 300mm. The minimum overlap length shall meet the specification requirements. According to the calculation of the overlap ratio, the vertical steel bar binding overlap position of the shear wall shall be turned up after the floor concrete of this floor is poured. Set steel joints about 1m apart. According to national standards, the overlap length of steel bars should be calculated according to the formula L=1.2d (1+λ)/α, where L is the overlap length, d is the diameter of the steel bar, λ is the length ratio of the stressed members, and α is the steel bar The ratio of tensile strength to the axial compressive strength of concrete.

Main components of steel plate
Chromium, copper, nickel and other alloying elements may also be added to the steel plate. These elements can improve the corrosion resistance and high-temperature strength of the steel plate. They are often used to manufacture steel plates in impact resistance, wear resistance, marine engineering, nuclear engineering and other fields.
