Is the shear wall concealed column stirrup steel or round steel?
Specify the construction drawing is HPB300 is hot rolled round bar, that is HRB335, HRB400 is the hot rolled ribbed bar. Don't call thread steel, this name has long been abandoned. Simple, light marked wall column reinforcement detail construction drawing on the diameter and spacing is not encrypted, what non encrypted area, like the dense spacing.
Round bar is the finished steel hot rolling and cooling, by ordinary low carbon steel and alloy steel under the condition of high temperature pressing, mainly used for reinforcement of reinforced concrete and prestressed concrete structure, is one of the varieties of steel used in civil engineering in the largest amount.
Now the shear walls, columns and stirrups are basically round steel bars, and their requirements are as follows: 6.5~12 mm in diameter steel bars, most of the reel into a disk; 12~40 mm in diameter, usually 6~12 meters long straight bar. I grade steel (Q235 steel) are rolling for smooth circular section, supply form of material, diameter of not more than 12mm, the length is 6m~12m.
