Abstract
The utility model relates to a longitudinal groove steel bar, which includes grooves longitudinally arranged on a reinforced bar. More than one limit clamp is arranged on the circumference of the reinforced bar, and specifically, limit clamping grooves are arranged at intervals on the reinforced bar, or limit clamping bulges are arranged at intervals on the reinforced bar. The longitudinal groove steel bar has simple structure and reasonable design, and enlarges the contact area of the steel bar and reinforcement stirrups, and mutual limiting function is adopted between the steel bar and reinforcement stirrups. The arrangement of the clamping grooves or the clamping bulges improves the precision of the spacing distances of the reinforcement stirrups, so that the quality of the whole framework of steel reinforcement is improved obviously, and the tolerance of a reinforced concrete structure is enhanced. Therefore, the utility model has a positive effect on the improvement of the resist compression, the bending resistance, shearing resistance and the earthquake resistance of buildings. The groove steel bar of the utility model has high tensile strength, can save raw materials compared with like products, and integrates the advantages of the existing steel bars.
Description
Technical field
The utility model relates to a kind of longitudinal groove reinforcing bar.
Background technology
At present, construction timber notched bars performance is single, though there is longitudinal groove on its surface, stirrup is lacked necessary force firm condition, i.e. stirrup displacement.When constituting whole cage of reinforcement, notched bars and little, the poor stability of stirrup contact area, when construction operation, easy generation binding is become flexible, tilts, is out of shape; Stirrup density generation error, in whole reinforced concrete structure, stirrup is subjected to force direction simple, brings into play stressed function and has shortcoming, and these problems all are disadvantageous to resistance to compression, tension, bending resistance, shearing resistance and the anti-seismic performance of whole reinforced concrete structure.Therefore, existing groove reinforcing bar only is suitable for and does lacing wire, uses and should not manufacture the concrete reinforcement skeleton.
Summary of the invention
The utility model is intended to overcome the deficiencies in the prior art, and the longitudinal groove reinforcing bar of a kind of tension, bending resistance, antidetonation is provided.
Longitudinal groove reinforcing bar of the present utility model is to have along vertical arrangement groove of muscle bar to constitute on the muscle bar, and the spacing card of one or more is arranged on week at the ring of muscle bar.
As further improvement of the utility model, on the muscle bar, be intervally distributed with spacing draw-in groove.
As further improvement of the utility model, it is protruding to be intervally distributed with spacing card on the muscle bar.
The utility model longitudinal groove reinforcing bar is reasonable in design, simple in structure, strengthened the contact area of reinforcing bar and stirrup, and has limit function each other; In whole reinforced concrete structure, the force firm effect of stirrup is obviously increased; Draw-in groove or block protruding setting and improved stirrup spacing distance accuracy; Make whole cage of reinforcement quality obviously improve, strengthened the reinforced concrete structure tolerance, resistance to compression, bending resistance, shearing resistance and the anti-seismic performance that improves building had positive role.Groove reinforcing bar of the present utility model is the tensile strength height not only, can save material compared with similar products, and integrate existing reinforcing bar advantage.

Fig. 2 is the structural representation that the surface of the utility model longitudinal groove reinforcing bar is provided with the cross spacing draw-in groove.
Fig. 3 is that the utility model longitudinal groove reinforcing bar muscle bar surface is provided with the protruding structural representation of card.
The specific embodiment
Longitudinal groove reinforcing bar of the present utility model is to have along vertical arrangement groove 2 of muscle bar 1 to constitute on muscle bar 1, at the ring of muscle bar 1 one or more spacing card 3 is arranged on week, as shown in Figure 1.
Longitudinal groove reinforcing bar of the present utility model is to have along vertical arrangement groove 2 of muscle bar 1 to constitute on muscle bar 1, is intervally distributed with one or more spacing draw-in groove 4 on week at the ring of muscle bar 1, as shown in Figure 2.
Longitudinal groove reinforcing bar of the present utility model is to have along vertical arrangement groove 2 of muscle bar 1 to constitute on muscle bar 1, and being has spacing card protruding 5 being intervally distributed with spacing card protruding 5 on the muscle bar 1 or dividing at interval on groove 2, as shown in Figure 3.
Claims (3)
