Abstract
The utility model discloses a novel concrete combination beam belongs to the building, for bridge structural element, and at present, traditional concrete beam owing to crackle etc. Self shortcoming appears from great, the roof beam body, can indirect influence the pleasing to the eye of structure and normal operating in the use, the utility model discloses in introducing concrete beam with the steel sheet, make both fellowship atresss, concrete slab is as the compression -flange ingeniously, and the steel sheet is as being drawn the edge of a wing, and bigger effect will be exert in both combinations, and intensity still is that rigidity has all improved greatly.
Description
Technical field
The present invention relates to a kind of building, bridge structural element, specifically a kind of new concrete compound beam.
Background technology
In use, due to concrete self, beam deadweight is comparatively large, easily occurs crack at beam soffit, have impact on the attractive in appearance of structure and normal use for traditional concrete beam, and this patent spy proposes a kind of new concrete compound beam, namely concrete combination beam lays concrete slab on girder steel, can be used for roof system, superstructure, also in the operating platform that may be used for industrial construction and bridge engineering, concrete slab and steel plate participate in stressed jointly, concrete slab is as compression flange, steel plate is as tension flange, structure height can be reduced, alleviate deadweight, and then reduce sectional dimension and the foundation load of vertical supporting member, reduce construction formwork and support, easy construction, both combine and will play larger effect, intensity or rigidity all substantially increases.
Summary of the invention
For solving the problem, a kind of new concrete compound beam of special proposition.
Technical solutions of the utility model are as follows.
A kind of new concrete compound beam, is characterized in that: comprise concrete slab, top flange steel plate, web steel plate, bottom flange steel plate, tack, stud and zigzag connector, realizes connecting between top flange steel plate, web steel plate, bottom flange steel plate by welding; Tack, stud and zigzag connector are welded on top flange surface of steel plate, make concrete slab realize being connected by tack, stud, zigzag connector with top flange steel plate.
The thickness of described top flange steel plate and bottom flange steel plate is 8 millimeters.
Described tack, stud, zigzag connector play shear connections effect, and zigzag connector shape is right-angled triangle.
Beneficial effect: the present utility model provides a kind of new concrete compound beam, the main pressurized of concrete, steel plate tension in compound beam cross section, given full play to material behavior, bearing capacity is high; Concrete slab participates in the work of beam, and the rigidity of beam increases, and when rigidity requirement is identical, adopts the comparable non-combined beam of compound beam to reduce depth of section 26%-30%; The frange plate of compound beam is more roomy, improves the lateral rigidity of girder steel, improves stability, improves the stress of pressure zone, enhances anti-fatigue performance simultaneously, and anti-seismic performance is good.

In figure, 1-concrete slab, 2-top flange steel plate, 3-web steel plate, 4-bottom flange steel plate, 5-tack, stud, 6-zigzag connector.
Detailed description of the invention
As shown in Figure 1, Figure 2 and Figure 3, according to the utility model patent, provide a kind of new concrete compound beam, comprise concrete slab 1, top flange steel plate 2, web steel plate 3, bottom flange steel plate 4, tack, stud 5 and zigzag connector 6; Realize connecting by welding between top flange steel plate 2, web steel plate 3, bottom flange steel plate 4, form an entirety; Tack, stud 5 and zigzag connector 6 are welded on top flange steel plate 2 surface, as shear connector, concrete slab 1 and top flange steel plate 2 are combined closely by tack, stud 5, zigzag connector 6.
The thickness of described top flange steel plate 2 and bottom flange steel plate 4 is 8 millimeters, ensures that steel plate has enough cross sections when tension; Described tack, stud 5, zigzag connector 6 play shear connections effect, the form of tack, stud is only adopted compared to conventional concrete compound beam, the utility model is in order to strengthen the connection function between steel plate and concrete slab, spy arranges zigzag connector 6 at top flange steel plate 2 external surface longitudinal centre line, and zigzag connector 6 profile is right-angled triangle.
Certainly; the present invention also can have other various embodiments; when not deviating from the present invention's spirit and essence thereof; those of ordinary skill in the art are when making various corresponding change and distortion according to the present invention, but these change accordingly and are out of shape the protection domain that all should belong to the claim appended by the present invention.
