Abstract
The invention relates to a steel tube concrete composite beam, comprising a steel tube concrete. One side of the steel tube concrete is connected with a flange through a ventral shield.
Description
(1) technical field
The present invention relates to the compound beam in a kind of civil engineering.
(2) background technology
Encased structures is to insert a kind of novel combining structure that forms in the steel pipe by concrete.Since concrete and two kinds of materials of steel pipe on mechanical property complementarity and steel pipe to the effect of contraction of fill concrete, make concrete filled steel tubular member can more effectively bring into play the advantage of steel and two kinds of materials of concrete; Simultaneously effectively overcome the shortcoming that cripling takes place steel tubular structure easily.Since five sixties of last century, concrete filled steel tube progressively begins to be applied in bridge engineering, heavy duty industrial factory building, stake and some structure.Especially over past 20 years, encased structures is applied to building structure especially in the high building structure gradually, and along with the increase of depth of building, the application of high strength concrete filled steel tube and steel pipe super high strength concrete structure also will be more and more widely.Yet encased structures can play good compound action when the steel duct concrete is under pressure owing to have only, and encased structures only is used to serve as compressed member at present.
(3) summary of the invention
The present invention will solve the limitation in the encased structures application successively, and a kind of steel tube concrete combination beam that has resistance to compression and tension advantage concurrently is provided, and enlarges the range of application of concrete filled steel tube.
Steel tube concrete combination beam of the present invention comprises concrete filled steel tube, it is characterized in that described concrete filled steel tube one side connects an edge of a wing by web.
Advantage of the present invention is to make full use of concrete filled steel tube good pressure resistance energy, and the good tensile property in the steel edge of a wing, enlarged the range of application of concrete filled steel tube, comparing it with common girder steel can avoid girder steel generation cripling to destroy, compare it with normal reinforced concrete beam and can reduce deadweight, improve bearing capacity.
(4) description of drawings
Fig. 1 is a cross-sectional view of the present invention
(5) embodiment
The present invention is by steel pipe inner concrete 1 and the steel pipe 2 and the tension edge of a wing 4 and be connected concrete filled steel tube and the web on the edge of a wing 4 is formed.
At the effect underbeam one side tension of moment of flexure, a side pressurized; So when selecting the good steel tube-concrete composite structure of compressive property can improve the anti-cripling damage capability of steel loop greatly, increase substantially concrete compressive property.This shows that this structure can reduce deadweight under identical external force effect, reduce construction costs.
