Abstract
The utility model discloses an I-shaped steel concrete beam, which comprises concrete and I-shaped steel serving as a framework in the beam, wherein the I-shaped steel is buried in the concrete. The I-shaped steel concrete beam is characterized in that the I-shaped steel comprises an upper flange and a lower flange; a vertical type web plate is arranged between the upper flange and the lower flange; and the surface of the vertical web plate is wavy. According to the I-shaped steel concrete beam, the surface of the vertical web plate is wavy and the vertical web plate can be made of a wavy thin steel plate, so that the adhesion between the I-shaped steel and the concrete can be improved, and the bearing capacity of the structural member can be greatly improved. Furthermore, besides that the vertical type web plate is the wavy thin steel plate, the upper flange and the lower flange are common steel plates; the vertical type web plate and the upper flange, as well as the lower flange are automatically welded and can be completely welded, so that the quality of a welded joint can be guaranteed, and a solid web framework with high performance is formed; and moreover, the requirement of building engineering is met, and steel materials can be greatly saved.
Description
Technical field
The utility model relates to the steel member that a kind of construction work is used, a kind of i shaped steel concrete beam especially wherein.
Background technology
Development along with building structure; The research and the application of steel-concrete combined structure are launched rapidly; So far become a kind of generally acknowledged new structural system, itself and steel work, wooden construction, masonry structure and reinforced concrete structure are arranged side by side, to be expanded into the fifth-largest structure.Steel-concrete combined structure has given full play to that concrete bears pressure and steel bear the mechanical properties of materials of pulling force; Secondly; The application of steel also helps the heavy in section of crossing of reducing concrete structure, and concrete material can reduce in the steel work the fireproof requirement the strong effect of steel.In addition, the combinations thereof structure also helps the improvement of anti-seismic performance.At present, steel-concrete combined structure is that steel-concrete combined structure is extensive in a lot of countries use, and domestic development also relatively rapidly.
What application was more in the steel-concrete combined structure is reinforced concrete composite structure, and so-called reinforced concrete composite structure is exactly the member of being processed by concrete coated steel.It comprises concrete and as the shaped steel of beam inner frame, shaped steel is imbedded in the concrete.Shaped steel in the steel reinforced concrete is except that adopting rolled section steel, and welding shaped steel also is widely used.The construction period of this steel-concrete combined structure is short; Shaped steel in the steel reinforced concrete is just molded before concreting; Have sizable supporting capacity, the changing load in the time of can bearing member dead weight with construction, and can template be suspended on the shaped steel; And needn't support be set, thereby can save the labour and the material of formwork for template; And the ductility of this structure and refractoriness are also higher.But; These steel-concrete combined structures are still in constantly improving and developing at present; Shaped steel as the beam inner frame all is to adopt common cross section structure; Such as I type, H type, I shape or grooved etc., yet deepen continuously, take some weakness and the limitation of the steel-concrete combined structure of above-mentioned cross section structure shaped steel to come out gradually along with what use and study.Because steel and concrete material hot expansibility differ greatly, the binding ability of two kinds of materials is not fine, As time goes on, at shaped steel and concrete frequent cracking at the interface, causes the decline of steel reinforced concrete performance.
This shows, demand developing a kind of reasonable stress, simple structure urgently and have the novel girder with rolled steel section en cased in concrete of load-carrying properties preferably.
The utility model content
The task of the utility model is to solve girder with rolled steel section en cased in concrete in the prior art, and especially the technological deficiency of i shaped steel concrete beam existence provides a kind of novel i shaped steel concrete beam.
Its technical solution is:
A kind of i shaped steel concrete beam comprises concrete and as the i iron of beam inner frame, i iron is embedded in the concrete; I iron comprises top flange and bottom flange, between top flange and bottom flange, is provided with vertical web; The plate face of above-mentioned vertical web is setback shape.
Above-mentioned vertical web adopts setback shape steel sheet to process.
Above-mentioned vertical web welds together with the upper and lower edge of a wing respectively.
Be formed with fillet weld between the above-mentioned vertical web and the upper and lower edge of a wing.
The thickness of above-mentioned vertical web is 2～4mm.
The thickness of above-mentioned vertical web is 3mm.
The utlity model has following useful technique effect:
In the utility model, the plate face of vertical web is setback shape, can adopt setback shape steel sheet to process, and i iron and concrete adhesive property is increased, thereby bearing of component is greatly enhanced.In addition, except that above-mentioned vertical web adopted setback shape steel sheet, general steel plate was all adopted on the upper and lower edge of a wing; And the thickness of setback shape steel plate can be decreased to about 3mm; Adopt the automatic welding promptly can complete penetration between the vertical web and the upper and lower edge of a wing, the weldquality of formation be enough to be guaranteed, and becomes the real abdomen skeleton of excellent performance; And when satisfying the construction work requirement, can also practice thrift steel greatly.Above-mentioned real abdomen skeleton part can be prefabricated in the factory, and helps practicing thrift on-site construction time.
Description of drawings
Below in conjunction with the accompanying drawing and the specific embodiment the utility model is described further:
Figure is the structural principle sketch map of a kind of embodiment of the utility model.
The specific embodiment
Referring to accompanying drawing, a kind of i shaped steel concrete beam comprises concrete 1 and as the i iron 2 of beam inner frame, i iron is embedded in the concrete.Above-mentioned i iron comprises top flange 201 and bottom flange 202, between top flange and bottom flange, is provided with vertical web 203, and the plate face of vertical web 203 is setback shape.Above-mentioned vertical web can adopt setback shape steel sheet to process, and vertical web is welded together to form real abdomen skeleton with the upper and lower edge of a wing respectively, is formed with fillet weld 204 between the vertical web and the upper and lower edge of a wing; Above-mentioned real abdomen skeleton part can be prefabricated in the factory.The thickness of above-mentioned vertical web can be 2～4mm, and preferred thickness is 3mm.
Above-mentioned setback shape steel sheet also can refer to waveform steel sheet or the crooked steel sheet of other plate face.
The relevant technologies content of not addressing in the aforesaid way is taked or is used for reference prior art and can realize.
Need to prove that those skilled in the art can also make such or such easy variation pattern under the instruction of this manual, such as equivalent way, or obvious mode of texturing.Above-mentioned variation pattern all should be within the protection domain of the utility model.
