H-Beam Characteristics
The inner and outer flanges of H-beam are parallel or close to parallel, and the end of flange is at right angle, so it is named parallel flange I-beam.
The thickness of the web of H-beam is smaller than that of the ordinary I-beam with the same height of the web, and the width of the flange is larger than that of the ordinary I-beam with the same height of the web, so it is also named as wide-edge I-beam. Determined by the shape, the
The section modulus, moment of inertia and corresponding strength of H-beam are significantly better than that of ordinary I-beam with the same single weight. H-beams are used in metal structures with different requirements, whether they Whether it is to bear bending moment, pressure load, eccentric load shows its superior performance, can be compared with the ordinary I-beam greatly improve the carrying capacity, saving metal 10% ~ 40%.
H-beam has wide flange, thin web, many specifications, flexible use, and can save 15%～20% of metal when used in various truss structures. Because of its wing
Because the inner and outer edges are parallel and the edge end is at right angle, it is easy to assemble and combine them into various components, which can save welding and riveting workload of about 25%, and can greatly speed up the construction speed and shorten the construction period.
It can greatly speed up the construction of the program and shorten the construction period.
