Problems solved by technology

[0004] However, in the prior art, for the wave web of the same specification, the wave height and wave pitch are constant, that is to say, the load bearing capacity of each part of the wave web is the same
In engineering structures, the loads borne by various parts of the components are generally different, so the wave webs with equal wave height and equal wave distance will not be fully utilized for the parts with smaller loads.

Abstract

The invention provides a wave web with a variable cross section. The wave web is characterized by being of periodically repeated waves along the length direction, wherein the heights and the pitches of waves of the wave web change gradually while the waves of the wave web are periodically repeated along the length direction, a wing plate is fixed on each of two sides of the wave web along the width direction to form an I-shaped member, the surfaces of the two wing plates are mutually parallel and are both vertical to the width direction of the wave web, and long sides of the wing plates are both parallel to the length direction of the wave web. According to the wave web, the heights and the pitches of the waves change along with the change of a load borne by a steel structure, so that all parts of the whole wave web approximately reach equal strengths, and thus the utilization rate of a metal material is maximally increased.

Description

technical field [0001] The invention provides a wave web with variable cross-section, which is mainly used in metal steel structure engineering. Background technique [0002] The web after wave forming has unique force characteristics, it has a very small compressive stiffness along the wavelength direction, and has a much higher cylindrical stiffness than a flat web of the same thickness along the wave height direction. Therefore, the corrugated web will not produce buckling under the longitudinal load of the member, but the ability to bear the shear load has been greatly improved. Therefore, the corrugated web can completely replace the same height but much thicker flat web member in engineering, thereby greatly reducing the amount of steel used in the structure. [0003] The wave web "I"-shaped member is composed of cold-rolled wave-shaped web and wing plate through high-frequency continuous welding. It is a new type of high-efficiency profile improved on the basis of or...
