Steel structure welded I-steel

Abstract

The invention belongs to the technical field of steel structure construction, and particularly relates to steel structure welded I-steel. The steel structure welded I-steel is characterized by comprising a horizontal upper flange plate and a lower flange plate connected with the upper flange plate through a vertical web; the upper flange plate is composed of a flange inclination steel plate and rounded corners arranged at the ends of the flange inclination steel plate, and the lower flange plate is composed of a flange inclination steel plate and rounded corners arranged at the ends of the flange inclination steel plate; and the upper flange plate and the lower flange plate are symmetrical about a horizontal central axis. The steel structure welded I-steel is formed by welding the flange plates with inclined planes, the excellent cross-section characteristics of traditional I-steel are retained, and the defect that large-cross-section structural profiles cannot be processed with the traditional I-steel is overcome.

Description

technical field [0001] The invention belongs to the technical field of steel structure buildings, and in particular relates to a steel structure welded I-beam. Background technique [0002] I-beam and H-beam, which are commonly used in traditional steel structure buildings, have been widely used in steel structure buildings due to their excellent cross-section properties, but there are certain deficiencies in the actual application process: 1. I-beam: The waist width of hot-rolled ordinary I-beams in my country is 100-630mm, and larger-sized materials are often required in construction to meet construction needs; 2. H-shaped steel: The advantage of H-shaped steel compared with I-beams is that it can be welded larger. The cross-sectional size of H-shaped steel meets the needs of construction, but because the H-shaped steel is welded by steel plates, there is no optimal design with a slope of 1:6 for the inner wall of the I-shaped steel leg, resulting in serious waste of materia...
