AI Technical Summary

Technical Problem

Existing fence posts consume a lot of materials and are costly, making it difficult to meet bending strength requirements while saving materials.

Method used

The fence post is designed with a "几"-shaped cross-section and is thinned. It has grooves symmetrically arranged along the length of the second and third side walls to increase the moment of inertia, disperse stress concentration, and improve bending strength. Screw fixing holes are provided on the fourth and fifth side walls to facilitate installation.

Benefits of technology

While reducing the thickness, it maintains or improves the bending strength, saves materials, reduces costs, and facilitates installation through screw fixing holes.

Abstract

The utility model discloses a material-saving thinned fence column, which comprises a strip-shaped section bar main body, the section bar main body comprises a first side wall, a second side wall and a third side wall which are respectively bent towards the same direction by 90 degrees along the left side and the right side of the length direction of the first side wall, and a fourth side wall and a fifth side wall which are respectively bent by 90 degrees along the outer sides of the second side wall and the third side wall, the second side wall and the third side wall are the same in width, at least one groove is formed in each of the second side wall and the third side wall in the length direction in a rolling mode, and the groove of the second side wall and the groove of the third side wall are symmetrical in position. The cross section of the fence column is designed to be in an n shape, the second side wall and the third side wall are symmetrically provided with the grooves arranged in the overall length direction of the fence column, and the grooves are optimized in geometrical shapes, so that the inertia moment is increased, local buckling is restrained, and stress concentration is dispersed, and therefore the bending resistance strength of the fence column is improved; while the thickness is reduced, certain anti-bending strength is ensured, materials are saved, and the cost is reduced.
