Reinforcing steel bar suitable for concrete

Abstract

The invention discloses a reinforcing steel bar suitable for concrete. The reinforcing steel bar suitable for the concrete comprises a reinforcing steel bar body and a plurality of transverse ribs; the transverse ribs protrude out of the reinforcing steel bar body; the maximal size of the cross section of the reinforcing steel bar body is d; the maximal size of the transverse ribs protruding out of the reinforcing steel bar body is h; the width of the top of the transverse ribs protruding out of the reinforcing steel bar body is defined as rib top width b; the distance between the two adjacent transverse ribs in the length direction of the reinforcing steel bar body is defined as rib spacing L; the transverse ribs are divided into two groups and arranged on the two sides of the reinforcing steel bar body correspondingly; the part of the cross section, between the two groups of transverse ribs, of the reinforcing steel bar body is a smooth curve or / and a straight line; the value range of the maximal size h of the transverse ribs protruding out of the reinforcing steel bar body is 0.08 d to 0.2 d; the value range of the rib spacing L is 0.3 d to 3 d. The reinforcing steel bar suitable for the concrete has the beneficial effects that the reinforcing steel bar body has smooth outline through improvement of the shape and the size parameters of the reinforcing steel bar, and a structure which has cracking risk when being combined with the concrete is eliminated, so that the firm degree of the reinforced concrete consisting of the reinforcing steel bar is increased.

Description

technical field [0001] The invention relates to a steel bar, in particular to a steel bar suitable for concrete. Background technique [0002] Reinforced concrete is often referred to as reinforced concrete in engineering. It refers to a composite material that works together to improve the mechanical properties of concrete by adding steel mesh, steel plates or fibers to the concrete. [0003] The reason why reinforced concrete can work together is determined by its own material properties. First of all, steel bars and concrete have approximately the same linear expansion coefficient, and excessive stress will not be generated due to different environments. Secondly, there is a good bond between the steel bar and the concrete. Sometimes the surface of the steel bar is also processed into ribs with intervals (called deformed steel bar) to improve the mechanical engagement between the concrete and the steel bar. However, this is still not enough to transmit the steel bar and...

Problems solved by technology

The steel bars currently used in the market cannot achieve higher strength due to unreasonable structures. When encountering disasters such as earthquakes and typhoons, they are prone to dangers such as fracture and collapse.
