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.
According to the rolling shape:
1.Smooth steel bars: Grade I steel bars (Q300 steel bars) are rolled for smooth circular cross-section, the supply form is disk circle, the diameter is not more than 10mm, the length is 6m~12m.
2. Ribbed steel: there are spiral, herringbone and crescent shape three, generally II , III grade steel rolled into adult shape, IV grade steel rolled into spiral and crescent shape.
3. Steel wire (divided into low carbon steel wire and carbon steel wire two kinds) and steel strand.
4. Cold rolled and twisted steel bars: cold rolled and cold twisted forming.
Diameter size:
Steel wire (diameter 3~5mm), fine steel bar (diameter 6~10mm), thick steel bar (diameter greater than 22mm).
Structure function:
Compression reinforcement, tension reinforcement, vertical reinforcement, distribution reinforcement, stirrup, etc
Product DetailsThere are many types of steel bars, usually classified by chemical composition, production process, rolled shape, supply form, diameter size, and use in the structure:
First, according to the size of the diameter
Steel wire (diameter 3~5mm), fine steel bar (diameter 6~10mm), thick steel bar (diameter greater than 22m
m).
Second, according to mechanical properties
Grade I steel (300/420); Grade II steel (335/455); Grade III (400/540) and Grade IV (500/630)
Three, according to the production process
Hot rolled, cold rolled, cold drawn steel bars, as well as IV grade steel by heat treatment of heat treatment of steel bars, the strength is higher than the former.
Four, according to the role in the structure
Compression reinforcement, tension reinforcement, vertical reinforcement, distribution reinforcement, stirrup, etc
The steel bar configured in the reinforced concrete structure can be divided into the following types according to its role:
1. Bearing bars - steel bars that withstand tensile and compressive stresses.
2. Stirrup - bear a part of the diagonal tension stress, and fix the position of the stress reinforcement, which is used in beams and columns.
3. Scaffolding - used to fix the position of the steel hoop in the beam, to form the steel skeleton in the beam.
4. Distribution reinforcement - Used in the roof panel and floor, vertical arrangement with the stress reinforcement of the plate, the weight of the load is evenly transmitted to the stress reinforcement, and the position of the stress reinforcement is fixed, and the temperature deformation caused by thermal expansion and contraction is resisted.
5. Other - structural reinforcement configured due to structural requirements of components or construction and installation needs. Such as waist reinforcement, embedded anchorage reinforcement, prestressed reinforcement, ring and so on.Product Parameters
1. Reinforced concrete with waste heat treatment of rebar waste heat treatment of rebar: immediately after hot rolling through water, surface control cooling, and then use the core waste heat itself to complete the finished steel bars obtained by tempering treatment.
2. Ribbed steel: The surface is usually with two longitudinal ribs and horizontal ribs evenly distributed along the length direction of the steel bar.
3. Crescent rib rebar: the longitudinal section of the transverse rib is crescent shaped, and the longitudinal rib does not intersect the rebar.
4. Longitudinal ribs: uniform continuous ribs parallel to the axis of the steel bar.
5. Transverse ribs: other ribs not parallel with longitudinal ribs.
6. Nominal diameter of ribbed steel bar: the diameter of a circle equal to the nominal cross-sectional area of the steel bar.
7. Relative rib area of ribbed steel bar: the ratio of the projected area of the transverse rib on the vertical plane of the axis of the steel bar to the product of the nominal circumference of the steel bar and the distance between the transverse ribs.
Rebar is now widely used in any building, for human progress has made better evidence, but also today's inspection of the quality of rebar members according to the minimum reinforcement rate of reinforcement, according to the principle of (equal area) replacement of rebar.
