Reinforced square steel tube

Abstract

A reinforced square steel pipe, comprising a square steel pipe body and reinforcement ribs on the four walls of the square steel pipe body, wherein the reinforcement ribs are longitudinally arranged on the square steel pipe, and the reinforcement ribs on the four walls of the square steel pipe are directed toward The inner cavity wall of the square steel pipe is recessed, and the reinforced ribs recessed in the inner cavity walls of the four walls of the square steel pipe form a trapezoidal inner cavity wall, and the trapezoidal sides of the trapezoidal inner cavity wall form the supporting surfaces of the four corners of the square steel pipe. The four corners of the square steel pipe are parallel, and the four corners of the parallel square steel pipe and the reinforcing ribs recessed toward the inner wall of the square steel pipe form a convex-concave square steel pipe wall; The convex-concave square tube wall increases the pressure-bearing surface of the square tube, thereby enhancing the technical effect of the load-bearing capacity, shear resistance and bending resistance of the square tube; the convex-concave square tube wall constitutes a beautiful appearance of the square tube , which increases its structural strength and obtains the beneficial technical effect of a beautiful structural appearance.

Description

technical field [0001] The invention relates to the technical field of shaped steel, in particular to a reinforced square steel pipe. Background technique [0002] At present, civil square steel pipes used for motor vehicle compartments, courtyard doors, fences, decorations, etc. are divided into thin-walled square steel pipes and thick-walled square steel pipes according to their uses. Thin-walled square steel pipes are used for impact strength requirements. For smaller structures, thick-walled square steel pipes are used for structures that require greater impact strength. However, there are still defects in the square steel pipes that are insufficient in shear and bending strength and easy to deform. The outer surfaces are smooth planes, so that the structure does not have an aesthetic appearance. Contents of the invention [0003] In order to solve the deficiencies of the prior art, the present invention provides a reinforced square steel pipe, which can not only repl...
