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
The invention provides a kind of variable cross-section wave webs, be mainly used in the metal steel structure engineering.
Background technology
Web after the wave moulding has unique loading characteristic, and it has minimum compressional stiffness along wavelength direction, along the wave height direction, has the cylinder rigidity more much higher than the flat web of same thickness.Therefore, it is bent that wave webs can not produce drum under the effect along the member longitudinal load, and the ability of bearing shearing resistance load has obtained increasing substantially.So wave webs can substitute equally highly much thick flat web component fully in engineering, thereby significantly reduces the structural steel amount.
Wave webs " work " shape member is comprised of by the high frequency continuous welding the Wave web of cold rolling moulding and wing plate, is to improve a kind of new and effective section bar formed on the basis of common " work " shape member.
But prior art is for the wave webs of same specification, its wave height and the pitch of waves are all constant, that is to say that the ability of each position institute bearing load of wave webs is identical.And, in engineering structures, the load that bear at each position of member is generally different, the wave height and wait the wave webs of the pitch of waves such as therefore, for bearing load, for less position, material just is not fully utilized.
Take a broad view of the metal steel structure Industry, be badly in need of a kind of can be according to the difference of institute's bearing load, the variable cross-section wave webs that wave height and the pitch of waves also change thereupon, to further improving the utilization rate of metal material.
Summary of the invention
The purpose of this invention is to provide and a kind ofly can overcome the existing existing defect of uniform section wave webs, the wave height of wave webs and the pitch of waves change along with the variation of steel work institute bearing load, make each position of whole wave webs reach approx " equal strength ", to improve to greatest extent the utilization rate of metal material.
Its technical scheme is: wave webs is the waveform for periodically repeating alongst, it is characterized in that: when the waveform of wave webs alongst periodically repeats, the wave height of wave webs and the pitch of waves change gradually thereupon.
Described variable cross-section wave webs, when the waveform of wave webs alongst periodically repeats, wave height and the pitch of waves of wave webs all reduce gradually.
Described variable cross-section wave webs, when the waveform of wave webs alongst periodically repeats, the wave height of wave webs reduces gradually, and the pitch of waves is constant.
" work " shape member that described variable cross-section wave webs forms, wave webs along the width both sides respectively fixedly a slice wing plate form " work " shape member, the plate face of two wing plates is parallel to each other, all perpendicular to the width of wave webs, and the long limit of wing plate all is parallel to the length direction of wave webs.
The present invention is on the prior art basis, adopt this technical scheme of variable cross-section wave webs, be the alongst waveform for periodically repeating of wave webs, when the waveform of wave webs alongst periodically repeats, the wave height of wave webs and the pitch of waves all reduce gradually thereupon; When perhaps the waveform of wave webs alongst periodically repeats, the wave height of wave webs reduces gradually thereupon, but the pitch of waves is constant.
Wave webs along the width both sides respectively fixedly a slice wing plate form " work " shape member, the plate face of two wing plates is parallel to each other, all perpendicular to the width of wave webs, and the long limit of wing plate all is parallel to the length direction of wave webs.
The present invention compared with prior art, adopts variable cross-section wave webs technology.Wave webs is alongst the waveform periodically repeated, when the waveform of wave webs alongst periodically repeats, the wave height of wave webs and the pitch of waves all can gradually change along with the size of wave webs institute bearing load, and the variation of the wave height of wave webs and the pitch of waves can make under the prerequisite that wave webs is equal at length, width and thickness, the consumption of material also changes thereupon in the same way.Be that wave height and the pitch of waves increase, the consumption of metal material and supporting capacity all increase thereupon; Otherwise wave height and the pitch of waves reduce, consumption and the supporting capacity of metal material all reduce thereupon.Therefore, adopt variable cross-section wave webs technology, can determine wave height and the pitch of waves of wave webs according to " equal strength " principle according to the size of institute's bearing load, to improve to greatest extent the utilization rate of metal material.
