Rebar refers to steel used for reinforced concrete and prestressed reinforced concrete, and its cross section is round, sometimes square with rounded corners. Including round steel bar, ribbed steel bar, torsion steel bar.
The steel bar for reinforced concrete refers to the straight bar or disc bar steel used for reinforced concrete reinforcement, and its shape is divided into two kinds of round steel bar and deformed steel bar, and the delivery status is straight bar and disc round two kinds.
The light round steel bar is actually a small round steel and disk circle of ordinary mild steel. Deformed bars are bars with ribbed surfaces, usually with two longitudinal ribs and transverse ribs evenly distributed along the length. The shape of the transverse rib is spiral shape, herringbone shape and crescent shape. Expressed in millimeters of nominal diameter. The nominal diameter of a deformed bar is equivalent to that of a circular bar of equal cross-section. The nominal diameter of the steel bar is 8-50 mm, and the recommended diameters are 8, 12, 16, 20, 25, 32, 40 mm. Steel grade: 20MnSi, 20MnV, 25MnSi, BS20MnSi. Steel bars are mainly subjected to tensile stress in concrete. Due to the action of the rib, the deformed steel bar has greater bonding capacity with the concrete, so it can better withstand the action of external forces. Steel reinforcement is widely used in various building structures. Especially large, heavy, light thin-walled and high-rise building structures.

Steel bars are widely used in construction engineering, is mainly used to reinforce and strengthen concrete structures, such as columns, beams, slabs, walls, etc. by embedding steel bars in concrete, can improve the tensile strength and seismic resistance of the structure. reinforced concrete structure is the foundation in construction engineering, steel in which the main tensile stress, its nominal diameter range of 8-50 mm, the diameter of the recommends including 16 8, 12, , , 20, 32, , , 25 40 mm. steel bars include 20MnSi, 20MnV, 25MnSi, BS20MnSi and so on.
In addition to concrete structures, steel bars are also used in prestressed structures, by applying prestressed force to concrete, makes concrete produce compressive stress under load, thereby improving the bearing capacity and overall stability of the structure. In the field of civil engineering, steel bars are used to reinforce and support Bridges, tunnels, piers and other structures, increase the stiffness and strength of structures, improve the bearing capacity and seismic performance of structures. In foundation engineering, steel bars are also used in foundation and foundation engineering of buildings, such as basements and underground pipelines, by installing steel bars, can enhance the stability and bearing capacity of foundation, prevent foundation settlement and damage.
In addition, the specific application of reinforcement in construction engineering also includes distribution reinforcement, through reinforcement, bearing reinforcement and stirrup and other forms. Distribution bars are used to fix the position of the loaded steel bars and distribute the load on the plate to the loaded steel bars; through bars run through the whole length of the member, without bending or breaking; The bearing bars are arranged at the lower part of the beam or plate to bear the tension; stirrup is used to meet the shear strength of the oblique section and to connect the main steel bar in tension with the concrete in the compression zone to make it work together.
