Description

Corrugated web T section abnormity steel column
Technical field
The utility model relates to a kind of new builing structure technical field, is specifically related to a kind of corrugated web T section abnormity steel column.
Background technology
In housing construction, special-shaped column structure has the incomparable advantage of other structural systems, and the parent being more and more subject to people looks at, and receives the great attention of Chinese scholars and engineering staff in recent years, thus obtains wider application.
But, in many high residential buildings, steel concrete deformed pile structure, due to be subject to column section limb long length depth ratio restriction and be difficult to meet requirement for bearing capacity, node region reinforcing bar is crowded, anti-seismic performance is undesirable and be difficult to process etc. problems, the advantage of hetermorphiscal column cannot be embodied comprehensively, thus limit its range of application, be difficult to promote.In order to overcome these deficiencies of shaped rc columns, there has been proposed all steel hetermorphiscal column.
In the Practical Project of multi and tall steel building house, its side column adopts traditional flat web steel flanged beam T section abnormity steel column or truss-like T 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 T 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 T 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.
Utility model content
The purpose of this utility model is to improve the existing T section abnormity stress performance of steel column and the comprehensive cost of unlikely remarkable its engineering of increase, special-shaped column structure is more widely used in many high residential buildings, a kind of corrugated web T section abnormity steel column is provided.
The technical solution adopted in the utility model is: a kind of corrugated web T section abnormity steel column, be welded to form by web H shaped steel and web T-steel, or be welded to form by two blocks of webs and three pieces of edges of a wing, described web is corrugated steel web, corrugated steel column web form is shaped form, fold-line-shaped or trapezoidal, corrugated steel web is in the corrugated limit of periodically repeating perpendicular to component length direction, and spot welding in the width on corrugated steel web non-corrugated limit and the edge of a wing, the described edge of a wing is plain plate or channel-section steel.
As preferably, the section form of described corrugated web T section abnormity steel column such as to comprise at limb and limb T section two class such as not.
Cross section of the present utility model is combined by corrugated web and frange plate.The essential structure of described steel column: can be welded by Ripple Sternum and corrugated web T-steel, or be welded by three pieces of plain plate edges of a wing and two pieces of corrugated webs.When described corrugated steel web and the steel plate edge of a wing are assembled into corrugated web T section steel column, the tie point on its corrugated steel web and the steel 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 utility model needs to ensure good welding process (can adopt welding technique).
Corrugated web arrangement of the present utility model: 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 utility model: 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 utility model is reasonable, and mechanical property is good, economy attractive in appearance, remarkable benefit, and development prospect is wide;
Steel column of the present utility model adopts all steel form, and therefore bearing capacity is high, ductility good, anti-seismic performance is excellent;
Web of the present utility model 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 utility model longitudinally need not set up longitudinal stiffener at component, labor and material saving, can reduce the integration engineering cost of engineering;
The utility model is compared with truss-like T section abnormity steel column, and simple structure, makes easy to process, quick, with low cost;
Compared with the utility model and truss-like T 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 utility model and steel flanged beam T 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 utility model is compared with steel flanged beam T section abnormity steel column, when cross-section steel materials are equal, increase depth of section, section modulus, second moment of area and the radius of gyration, improve bending rigidity and stability bearing capacity that steel utilize usefulness and steel column;
The utility model, from heavy and light, can alleviate dead load, thus reduces the pressure to ground, can reduce the cost of foundation;
The utility model has expanded the research and apply field of steel column, has greatly enriched steel work content.
The utility model can provide novel critical component for the exploitation of new steel structure dwelling house system, has good conversion prospect.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is generalized section of the present utility model.
Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the utility model is described further.
As illustrated in fig. 1 and 2: a kind of corrugated web T section abnormity steel column, be welded to form by web H shaped steel and web T-steel, or be welded to form by two blocks of webs and three pieces of edges of a wing 1, described web is corrugated steel web 2, corrugated steel column web 2 form is shaped form, fold-line-shaped or trapezoidal, corrugated steel web 2 is in the corrugated limit of periodically repeating perpendicular to component length direction, and spot welding in the width on corrugated steel web 2 non-corrugated limit and the edge of a wing 1, the described edge of a wing 1 is plain plate or channel-section steel.The section form of described corrugated web T section abnormity steel column such as to comprise at limb and limb T section two class such as not.
The usual plain plate edge of a wing of the utility model, corrugated steel web and be welded on factory process and complete.
Its basic production process is: making corrugated steel web → making steel edge of a wing → weld → transport to job site → hoisted in position.
