Abstract
The utility model discloses a corrugated steel web-concrete filled steel tube edge of a wing combination section box post links together by two webs and two edges of a wing and constitutes the box structure, the web is corrugated steel web, and corrugated steel web is periodic repeated corrugated limit perpendicular to component length direction, and the non-corrugated limit of corrugated steel web welds with the both ends of the width on the edge of a wing, the edge of a wing is the concrete filled steel tube edge of a wing, and the concrete filled steel tube edge of a wing includes steel pipe and inside concrete, and the concrete is self-compaction concrete. The utility model discloses improved the atress performance of current flat web box cross-section steel column and unlikely to show the comprehensive cost that increases its engineering again, made it can the wide application in the engineering.
Description
Technical field
The utility model relates to a kind of new builing structure technical field, is specifically related to a kind of corrugated steel web-compound section, concrete filled steel tube edge of a wing box column.
Background technology
Multi and tall steel building, the status in China's modernization construction becomes increasingly conspicuous, and the parent being more and more subject to people looks at, and is subject to the great attention of Chinese scholars and engineers and technicians in recent years, thus is used widely.
In the Practical Project of multi and tall steel building, particularly at load comparatively large or to the antitorque requirement of component higher require component surface smooth or closed, the flat web box section steel column that usual employing is traditional, and its sectional dimension is usually very large, particularly web size.In order to ensure the local stability of web, meeting the web ratio of height to thickness limit value of " Code for design of steel structures " defined, usually or increase its web thickness, or setting up its longitudinal stiffener.No matter adopt which kind of scheme, all will cause increasing steel consumption, increase construction cost, thus increase the comprehensive cost of engineering.And when moment of flexure effect is larger, the edge of a wing of steel column, may enter failure state too early, causes steel column to lose its drag very soon; Meanwhile, steel column is pure steel structure, and its fire resistance is poor.
Utility model content
The purpose of this utility model is the comprehensive cost of stress performance in order to improve existing flat web box section steel column unlikely remarkable its engineering of increase again, make it in engineering, be able to extensive use, a kind of corrugated steel web-compound section, concrete filled steel tube edge of a wing box column is provided.
The technical solution adopted in the utility model is: a kind of corrugated steel web-compound section, concrete filled steel tube edge of a wing box column, linked together by two blocks of webs and two pieces of edges of a wing and form box structure, described web is corrugated steel web, the corrugated limit of corrugated steel web in periodically repetition is perpendicular to component length direction, corrugated steel web non-corrugated limit is welded with the two ends of the width on the edge of a wing, the described edge of a wing is the concrete filled steel tube edge of a wing, the concrete filled steel tube edge of a wing comprises the concrete of steel pipe and inside thereof, and concrete is self-compacting concrete.
As preferably, described corrugated steel web form is shaped form, fold-line-shaped or trapezoidal.
Cross section of the present utility model is combined by corrugated steel web and the concrete filled steel tube edge of a wing.Concrete generation type is: the steel-pipe welding on corrugated steel web and the concrete filled steel tube edge of a wing, in the most backward steel pipe, fluid concrete combines.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).The edge of a wing is formed by steel pipe and Combined concrete, and due to the limited space in steel pipe, therefore during fluid concrete, inconvenience is vibrated, therefore should select self-compacting concrete.
Essential characteristic of the present utility model: in comparatively economic mode, improve the stress performance of existing box steel column.The utility model put mode corrugated web can play equivalent longitudinal stiffener effect, the local stability of web and the monolithic stability bearing capacity of steel column can be improved; Penetration concrete in the steel pipe of the edge of a wing, improves local stability and the refractory ability of steel pipe.Therefore, the utility model section constitution is reasonable, and mechanical property is good; Fire-resistant, antiseptic property good; Simple structure, make easy to process, quick, labor and material saving, engineering cost is low.
Beneficial effect: New type corrugated web of the present utility model-compound section, concrete filled steel tube edge of a wing box column, simple structure, makes easy to process, quick, with low cost;
Rationally, mechanical property is good for cross section of the present utility model composition;
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;
Web of the present utility model adopt put the corrugated web of mode, improve the monolithic stability bearing capacity of steel column;
The utility model corrugated web can break through the ratio of height to thickness restriction of Code for design of steel structures defined, can reduce web thickness, saving steel, reducing engineering comprehensive cost when not reducing bearing capacity;
The utility model need not set up longitudinal stiffener, labor and material saving, can reduce the integration engineering cost of engineering;
The edge of a wing of the present utility model steel pipe concrete filled, enhances the fire resistance of coupled column;
The concrete filled steel tube that the edge of a wing of the present utility model adopts institute to put mode combines the edge of a wing, improves edge of a wing local stability, thus improves the stability of whole coupled 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-concrete coupled 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 steel web-compound section, concrete filled steel tube edge of a wing box column, linked together by two blocks of webs and two pieces of edges of a wing and form box structure, described web is corrugated steel web 2, the corrugated limit of corrugated steel web 2 in periodically repetition is perpendicular to component length direction, corrugated steel web 2 non-corrugated limit is welded with the two ends of the width on the edge of a wing, the described edge of a wing is the concrete filled steel tube edge of a wing 1, the concrete filled steel tube edge of a wing 1 comprises the concrete of steel pipe and inside thereof, and concrete is self-compacting concrete.Described corrugated steel web 2 form is shaped form, fold-line-shaped or trapezoidal.
The usual steel pipe of the utility model, corrugated steel web and be welded on factory process and complete; In steel pipe, fluid concrete then completes at the construction field (site).
Its basic production process is: make corrugated steel web → making steel pipe → weld → transport to job site → hoisted in position → to fluid concrete in steel pipe.
It should be pointed out that for those skilled in the art, under the prerequisite not departing from the utility model principle, can also make some improvements and modifications, these improvements and modifications also should be considered as protection domain of the present utility model.The all available prior art of each ingredient not clear and definite in the present embodiment is realized.
