Equilateral triangle prismatic reinforcing bar section

Abstract

The invention discloses an equilateral triangle prismatic reinforcing bar section consisting of an inner base, transverse bars and longitudinal bars. The equilateral triangle prismatic reinforcing bar section is characterized in that the section of the inner base is in an equilateral triangle prismatic shape; the equilateral triangle prism is a polygonal surface formed by inwards concaving each side of an equilateral triangle; three sides of the equilateral triangle prism are respectively inverted V-shaped; three angles of the equilateral triangle prism are connected with the three sides of the equilateral triangle prism into a whole and are connected with square longitudinal bars; three inverted V-shaped surfaces of the equilateral triangle prism are connected with the equilateral triangle prism into a whole; and a plurality of crescent, inverted V-shaped or angular, herringbone or twisted strip transverse bars are arranged on the three inverted V-shaped surfaces. The invention has the advantages that the perimeter of the section of the reinforcing bar section is longer; the three surfaces of the equilateral triangle prim have large surface friction force, so that the bond stress, the tensile strength and the vibration resistant capability of reinforcing bars in the concrete can be remarkably improved; meanwhile, the compression resistant, bending resistant, bending resistant and twisting resistant forces are stronger than those of the traditional reinforcing bar section. The reinforcing bar section is suitable for large-sized piers, dams, upright posts of expressway bridges, building top columns, tunnels and the like and is an ideal equilateral triangle prismatic reinforcing bar section.

Description

technical field [0001] The invention relates to a steel bar profile, in particular to a steel bar profile with an equilateral triangular prism in section. Background technique [0002] On February 21, 1998, the applicant himself applied for an invention patent entitled "Equilateral Triangular Reinforced Concrete Profile", the application number is "98106507.4", and the authorized announcement number is "CN1094546C". This invention patent document discloses a steel bar profile with an equilateral triangle cross section. Although the steel bar profile with this cross-sectional shape has higher tensile, compressive, flexural, bending and twisting resistance than the commonly used threaded steel bar at present At the same time, it also has a high anti-vibration ability; but because the three faces of the equilateral triangle are planes, the surface friction force is small, and the gripping force of the steel bar in the concrete and the increase in the anti-vibration ability are ...
