Abstract
The invention discloses a special-shaped steel column with a corrugated web plate L-shaped section, which comprises a first flat steel plate flange, a second flat steel plate flange, a third flat steel plate flange, a first steel web plate and a second steel web plate, wherein one side edge of the second steel web plate is vertically connected with the edge of the first steel web plate to form the special-shaped steel column with the L-shaped section, the first steel web plate and the second steel web plate are corrugated steel web plates, the web plates of the corrugated steel columns are in a curve shape, a fold line shape or a trapezoid shape, periodically repeated corrugated edges of the corrugated steel web plates are perpendicular to the length direction of a member, and non-corrugated edges of the corrugated steel web plates are respectively welded with the width midpoints of the first steel plate flange, the second flat steel. The invention improves the stress performance of the existing L-shaped section special-shaped steel column without obviously increasing the comprehensive construction cost of the engineering, and the invention can be widely applied to the engineering.
Description
Technical field
The present invention relates to a kind of new builing structure technical field, be specifically related to a kind of corrugated web L tee section abnormity steel column.
Background technology
In the modernization construction of multi and tall steel building house, the advantage of special-shaped column structure is more and more remarkable, and status becomes increasingly conspicuous, and is subject to domestic and international academia and the common great attention of engineering personage in recent years, development rapidly, makes its application in engineering also more and more extensive.
In the Practical Project of multi and tall steel building house, its corner post adopts traditional flat web steel flanged beam L tee section abnormity steel column or truss-like L tee section abnormity steel column usually.In order to meet the requirement of bending stress performance, usually need larger sectional dimension, particularly web size.If select traditional flat web steel flanged beam L tee section abnormity steel column, its web shear strength can be had more than needed a lot, but in order to ensure the local stability of web, meet the web ratio of height to thickness limit value of " Code for design of steel structures " defined, usually need again to increase its web thickness, this will cause increasing steel consumption, increase engineering cost, thus add engineering comprehensive cost; If select truss-like L tee section abnormity steel column, except its shear-carrying capacity, anti-seismic performance and overall stability are limited, its truss-like web member needs batten plate or lacing to be welded, construct relatively loaded down with trivial details, connect workload comparatively large, increase construction cost, thus also increase the comprehensive cost of engineering.
Summary of the invention
The object of the invention is to the comprehensive cost of stress performance unlikely remarkable its engineering of increase again in order to improve existing L tee section abnormity steel column, making it in engineering, be able to extensive use, a kind of corrugated web L tee section abnormity steel column is provided.
The technical solution used in the present invention is: a kind of corrugated web L tee section abnormity steel column, comprise the plain plate edge of a wing one, the plain plate edge of a wing two, the plain plate edge of a wing three, steel web one and steel web two, a side of described steel web two is connected with the edge of steel web one is vertical, form L tee section abnormity steel column, described steel web one and steel web two are corrugated steel web, corrugated steel column web form is shaped form, fold-line-shaped or trapezoidal, the corrugated limit of corrugated steel web in periodically repetition is perpendicular to component length direction, corrugated steel web non-corrugated limit respectively with the steel plate edge of a wing one, the plain plate edge of a wing two, spot welding in the width on the plain plate edge of a wing three.
Cross section of the present invention is combined by corrugated steel web and the plain plate edge of a wing.The essential structure of described steel column: can be welded with a slice corrugated web T-steel by a slice Ripple Sternum or two panels corrugated steel web welds with three plain plate edges of a wing and combines.When described corrugated steel web and the plain plate edge of a wing are assembled into corrugated web L tee section steel column, the tie point on its corrugated steel web and the plain plate edge of a wing should be positioned at the width mid point on the plain plate edge of a wing.In section constitution, welding process and welding quality can directly affect steel column performance, and for this reason, the present invention needs to ensure good welding process (can adopt welding technique).
Corrugated web arrangement of the present invention: web is in the corrugated limit of periodically repeating perpendicular to component length direction, and web non-corrugated limit is welded with the dull and stereotyped edge of a wing.This constituted mode can make corrugated web play outside conventional web effect, also can play equivalent longitudinal stiffener effect, can improve local stability and the monolithic stability bearing capacity of web.Essential characteristic of the present invention: in comparatively economic mode, improves the stress performance of existing L tee section abnormity steel column, improves rigidity and the stability bearing capacity of steel column; Section constitution is reasonable, and mechanical property is good; Simple structure, make easy to process, quick, labor and material saving, engineering cost is low.
Beneficial effect: section constitution of the present invention is reasonable, and mechanical property is good, economy attractive in appearance, remarkable benefit, and development prospect is wide;
Steel column of the present invention adopts all steel form, and therefore bearing capacity is high, ductility good, anti-seismic performance is excellent;
Web of the present invention adopt put the corrugated web of mode, form equivalent longitudinal stiffener effect, the local stability of web can be improved, and improve the monolithic stability bearing capacity of steel column;
The present invention longitudinally need not set up longitudinal stiffener at component, labor and material saving, can reduce the integration engineering cost of engineering;
The present invention is compared with truss-like L tee section abnormity steel column, and simple structure, makes easy to process, quick, with low cost;
Compared with the present invention and truss-like L tee section abnormity steel column, its shear-carrying capacity is high, ductility and anti-seismic performance good, monolithic stability bearing capacity is superior;
Compared with the present invention and steel flanged beam L tee section abnormity steel column, when depth of section is equal, its steel using amount is few, from heavy and light, can saving steel, and reduce engineering cost;
The present invention, compared with steel flanged beam L tee section abnormity steel column, when cross-section steel materials are equal, increases section modulus, second moment of area and the radius of gyration, improves bending rigidity and stability bearing capacity that steel utilize usefulness and steel column;
The present invention, from heavy and light, can alleviate dead load, thus reduces the pressure to ground, can reduce the cost of foundation;
The present invention is a kind of Novel special-shaped post being specially adapted to housing building of steel-structure, has expanded the research and apply field of steel column, has greatly enriched the content of steel structure column.
The present invention can provide novel critical component for the exploitation of new steel structure dwelling house system, has good conversion prospect.
