Problems solved by technology

However, since the square ribs are set independently, when one square rib is subjected to force, the other square ribs cannot play a good role in dispersing the force, and then these square ribs will be destroyed one by one until the entire building material fails

Embodiment Construction

[0010] The present invention will be described in detail below in conjunction with the drawings.

[0011] Such as figure 1 Shown: a light-weight convex-reinforced steel bar, a light-weight convex-reinforced steel bar, includes a rebar body 1 which is a hollow structure and has spiral ribs 2 provided on its outer surface.

[0012] The diameter of the spiral blade of the spiral rib 2 is 2 to 4 times the diameter of the steel body 1.

[0013] Because the spiral rib 2 is a continuous structure, the entire steel bar will be stressed when it is subjected to tensile stress, so that it will take more force in the concrete, and the friction and bite force will be large. When the concrete is subjected to strong bending, etc. At this time, the concrete is not easy to slip, thus increasing the strength of the square rib building materials, so as to achieve the purpose of more effort in the concrete and high friction.

Abstract

The invention provides a light convex-rib steel bar. The light convex-rib steel bar comprises a steel bar body, wherein the steel bar body is a hollow structure, and is provided with a spiral convex rib on the outer surface; and the spiral blade diameter of the spiral convex rib is 2-4 times of the diameter of the steel bar. As the spiral convex rib is a continuous structure, the steel bar is wholly stressed when being suffered from the tensile stress, the stress in concrete is high, and the frictional force and the bite force are great; and when the concrete is suffered from such great force as bending, the steel bar is difficult to slip in the concrete, so that the strength of a square convex rib building material is improved, and the purposes of higher stress in the concrete and great frictional force are achieved.

Description

Technical field [0001] The invention relates to the field of construction, in particular to a light-weight convex reinforcement steel bar. Background technique [0002] The invention patent No. 200510126674.7 discloses a square rib building material. This kind of building material is provided with a plurality of square ribs on the main body of the steel bar. The square ribs can be more closely occluded with the concrete when subjected to external force to improve the friction. . However, because the square ribs are set independently, when one square rib receives a force, the other square ribs cannot play a good role in dispersing the force, and these square ribs will be destroyed one by one until the entire building material fails. Summary of the invention [0003] In order to solve the above-mentioned problems, the present invention provides a lightweight convex reinforcement steel bar. [0004] The specific solution is as follows: a light-weight convex-reinforced steel bar, and ...
