Description
Technical Field
The utility model relates to a novel steel pipe concrete edge of a wing-ripple web combination beam belongs to building structure technical field.
Background
Steel-concrete composite beams have been gaining increasing attention in recent decades because of their many advantages. Compared with the traditional reinforced concrete beam, the steel-concrete composite beam has the advantages of higher rigidity, greatly improved ductility, light dead weight, better prefabrication and assembly performance, strong seismic resistance and energy consumption capacity and the like. However, there are typical problems, such as that the medium-sized steel section of the combined section is weaker than the concrete section, the overall instability and the local instability are caused, and the buckling before yielding occurs because the web is mostly free from the concrete constraint, so that the shear-resistant bearing capacity of the beam is reduced.
SUMMERY OF THE UTILITY MODEL
The purpose is as follows: in order to overcome the defects in the prior art, the utility model provides a novel concrete filled steel tube flange-corrugated web composite beam.
The technical scheme is as follows: in order to solve the technical problem, the utility model discloses a technical scheme does:
a novel steel pipe concrete flange-corrugated web composite beam comprises a rectangular steel pipe, U-shaped channel steel and a corrugated web for connecting the rectangular steel pipe and the U-shaped channel steel; concrete is filled in the rectangular steel pipe and the U-shaped channel steel, a concrete slab is arranged above the rectangular steel pipe, and the concrete slab and the rectangular steel pipe are connected through studs.
Furthermore, the corrugated web plate is connected with the rectangular steel pipe and the U-shaped channel steel through welding seams.
Further, the width of the U-shaped channel steel is larger than that of the rectangular steel pipe, and the width of the U-shaped channel steel is smaller than that of the concrete slab.
Further, the lower end of the corrugated web plate is located at the axial center of the U-shaped channel steel.
Further, a steel reinforcement framework is arranged in the concrete slab.
Further, the rectangular steel pipe, the U-shaped channel steel and the corrugated web plate are made of Q345 steel or Q420 steel.
Has the advantages that: the utility model provides a pair of novel steel pipe concrete edge of a wing-corrugated web composite beam uses the steel pipe intussuseption concrete to replace the straight board edge of a wing of I-steel, uses the channel-section steel intussuseption concrete as the bottom flange, adopts the corrugated web can effectively improve the bearing capacity that shears of roof beam simultaneously, improves the edge of a wing to the constraint effect of web, has alleviateed the buckling phenomenon of web.

Detailed Description
The present invention will be further described with reference to the accompanying drawings.
As shown in fig. 1 and 2, the novel steel pipe concrete flange-corrugated web composite beam comprises a rectangular steel pipe 1, a U-shaped channel steel 2 and a corrugated web 3 for connecting the rectangular steel pipe 1 and the U-shaped channel steel 2, wherein concrete is filled in the rectangular steel pipe 1 and the U-shaped channel steel 2, a concrete slab 4 is arranged above the rectangular steel pipe 1, and the concrete slab 4 is connected with the rectangular steel pipe 1 through a stud 6. And a steel reinforcement framework 7 is arranged in the concrete slab 4.
The steel pipe concrete is used for replacing the flange of the I-shaped steel straight plate, and under the condition of the same steel consumption, the section is narrower, and the out-of-plane rigidity is reduced to some extent. The concrete slab is arranged above the rectangular steel pipe, the upper flange can be guaranteed not to be unstable under the constraint action of the concrete slab on the steel pipe, the stability of the compression flange is enhanced on the one hand, the problem that the steel plate is lifted in the compression area is avoided, the rigidity of the flange of the pipe on the other hand is larger, the local pressure borne by the corrugated web plate is effectively relieved, the constraint action of the flange on the web plate is improved, and the buckling linearity of the web plate is reduced.
The bottom flange adopts the channel-section steel intussuseption concrete as the optimization of pipe edge of a wing, compares the straight board edge of a wing and has the advantage on the pipe edge of a wing equally, can also further reduce with the steel volume on the basis of pipe edge of a wing to enlarge the bottom flange cross-section, guarantee edge of a wing stability and the bending resistance bearing capacity in hogging moment district.
The web plate is a corrugated plate, so that buckling after yielding can be realized, and the material strength is fully exerted.
The width of U type channel-section steel 2 is greater than the width of rectangle steel pipe 1, and the width of U type channel-section steel 2 is less than concrete slab 4's width.
The rectangular steel pipe 1, the U-shaped channel steel 2 and the corrugated web plate 3 are made of Q345 steel or Q420 steel.
The above description is only a preferred embodiment of the present invention, and it should be noted that: for those skilled in the art, without departing from the principle of the present invention, several improvements and modifications can be made, and these improvements and modifications should also be considered as the protection scope of the present invention.
