Abstract
The utility model relates to a high-strength groove reinforcement bar which is formed by in the way that three to seven longitudinal spiral grooves are arranged on the column body of the reinforcement bar. The groove bottom of the groove is a convex surface; the section of the groove is an arc surface raised upward, or is in a W shape or an M shape. The high-strength groove reinforcement bar is novel construction steel newly developed on the basis of cold rolled strip reinforcement bars; by the specific equipment, the reinforcement bars with same continuous spiral W-shaped or M-shaped grooves on the surfaces are processed. The lead is long, the thread pitch is small, and the appearance is provided with a plurality of grooves and is in a spiral shape, so the utility model has moderate strength, good plasticity and strong bondability, and is universally applied to stressed reinforcement bars, floor reinforcement bar pavement, beam column hoping and the like of reinforced concrete members. The utility model has the advantages of energy saving, consumption reduction, construction cost reduction and the like.
Description
Technical field
The utility model relates to a kind of high strength groove reinforcing bar.
Background technology
At present, the reinforcing bar that uses in the construction, a kind of is Ribbed Bar, this reinforcing bar is cold rolling through multiple tracks with circular blank, shuts out on the roll with pass then.Because its deflection is too high, its plasticity index descends, elongation per unit length is low.A kind of is cold-rolled torsion steel bar, and this reinforcing bar is to flatten on the duo mill plain-barreled roll with the hot rolling circular blank, is reversed into screw type then.Because the blank side is easy to cracking during through flattening, its elongation per unit length is also low and unstable properties, makes its range of application limited.
Summary of the invention
The utility model is intended to overcome the deficiencies in the prior art, and the high strength groove reinforcing bar of a kind of tension, bending resistance is provided.
The utility model high strength groove reinforcing bar is to be provided with the longitudinal spiral groove to constitute on the cylinder of reinforcing bar, and the bottom land of described groove is a convex surface.
As further improvement of the utility model, the cross section of described groove is the arcwall face of last projection.
As further improvement of the utility model, the cross section of described groove is a W shape.
As further improvement of the utility model, the cross section of described groove is a M shape.
As further improvement of the utility model, the cylinder of described reinforcing bar is provided with 3～7 grooves of ring Zhou Junbu.
High strength groove reinforcing bar of the present utility model is on the basis of cold rolled reinforcing steel bar with ribs, and steel a kind of for building newly developed utilize special equipment, processes the surface and is continuously that helical form, groove are the reinforcing bar of arcwall face, W shape or M shape.Its helical pitch is big, pitch is little, profile multiple-grooved and shape in the shape of a spiral, thereby intensity is moderate, plasticity is good, bond stress is strong, can be widely used in steel bar stress, the floor shop muscle, beam column stirrup of reinforced concrete member etc., its have energy-saving and cost-reducing, reduce advantage such as building costs.
