Abstract

The invention discloses a steel-concrete combination beam ,including a concrete beam (1), characterized in that a waveform steel plate (2) is arranged in concrete beam (1), because the waveform steel plate has advantage of light quality, high shear resistant yield strength, and the waveform steel web plate can not resist acting axial force and so that can efficiently exert prestressing force for concrete beam, and the waveform steel plate can not restrain the deformation caused by slow changing and drying shrinkage of the enwrapped concrete, avoiding the prestress damage of beam cross section caused by constraining action of steel plate, additionally, the shear resistant connecting key formed naturally between the concrete and the waveform steel plate joins them into a whole, the beam has good integrity and high fatigue resistance, so the invention can improve stability of whole structure for the concrete beam.

Description

technical field

[0001] The invention relates to a composite beam, in particular to a steel-concrete composite beam. Background technique

[0002] Existing steel-concrete composite beams generally have the following types: steel-concrete structure, steel pipe concrete structure, outsourcing concrete structure, and pre-bent composite beam structure. A common feature of the above methods is to combine steel and concrete. They have the problem of internal stress of the beam caused by factors such as the difference in thermal expansion coefficient between steel and concrete, and the creep of concrete. Contents of the invention

[0003] The invention provides a steel-concrete composite beam with strong overall structural stability.

[0004] The present invention adopts following technical scheme:

[0005] A steel-concrete composite beam includes a concrete beam in which a corrugated steel plate is arranged.

[0006] Compared with the prior art, the present invention has the f...
