Reinforcing steel bar applicable to concrete

Abstract

The invention discloses a steel bar suitable for concrete, which comprises a steel bar body and several transverse ribs, the transverse ribs protrude from the steel bar body, the maximum dimension of the cross section of the steel bar body is d, and the maximum dimension of the transverse rib protruding from the steel bar body is h, the width of the top of the transverse rib protruding from the steel bar body is defined as the rib top width b, and the distance between two adjacent transverse ribs in the length direction of the steel bar body is defined as the rib spacing L; the transverse ribs are divided into two groups , respectively set on both sides of the steel bar body; the cross section of the steel bar body is a smooth curve or \ and straight line between the two sets of transverse ribs; the value range of the maximum dimension of the transverse rib protruding from the steel bar body is 0.08 d to 0.2d; the range of rib top width b is 0.05d to 0.15d. The benefit of the present invention is that by improving the shape and size parameters of the steel bar, the steel bar body has a relatively smooth outer contour, eliminating the structure with the risk of cracking when combined with concrete, thereby improving the firmness of the reinforced concrete made of steel bars.

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.
