Abstract
The utility model provides a strengthened corrugated steel web plate shear connector for combined box girder and mainly solves the technical problems that the junction part of the web plate and the concrete top plate and concrete bottom plate in box girder is easy to have transverse flexural deformation, so as to be unable to satisfy design requirements. The utility model comprises a corrugated steel web plate; a steel plate belt or a strengthening block is welded on the surface of the steel web plate on the junction part; the width of the steel plate belt or the strengthening block is 100-150mm and the thickness of the steel plate belt or the strengthening block is 8-12mm. the shear connecter structure increases the anti-shearing area of concrete pin in unit length on the junction part, so as to improve vertical anti-shearing ability and transverse bending resistance of the junction part; furthermore, the optimization design of steel web plate is realized.
Description
Technical field
The utility model relates to the Wavelike steel webplate case beam technology in the bridge, the joint construction between concrete is a kind of Wavelike steel webplate and concrete top, the base plate.
Background technology
Generally use the main body bearing structure of the case beam of Wavelike steel webplate and concrete top, base plate formula in the existing bridge construction as whole bridge.Its form of structure is as follows: its top, base plate adopt concrete structure, and Wavelike steel webplate is used in its both sides, is combined into the box structure body.Because bridge should carry bigger dead load and dynamic load, has big shearing action at Wavelike steel webplate and concrete top, base plate binding site place.In order to guarantee under the design load effect, to make Wavelike steel webplate not produce shear strain basically, several joint construction forms below main at present employing the: (1), flush type joint construction.Referring to Fig. 1 a, the two ends up and down of the Wavelike steel webplate 1` of both sides are directly stretched in the concrete structure of top, base plate (top, base plate are not shown among the figure), link to each other with top, base plate by concrete pin shear connector at two ends up and down at Wavelike steel webplate; Shear connector shown in the figure passes running through reinforcing bar 3` and retraining reinforcing bar 4` formation of through hole 2` mainly by through hole 2`.(2), edge of a wing type joint construction.Referring to Fig. 1 b, Fig. 1 c.Two ends up and down at Wavelike steel webplate 1 are welded with frange plate 5`, and welding has the perforated panel 6` of through hole 2` on frange plate again, and this perforated panel is connected with top, base plate as running through reinforcing bar 3` etc. by concrete pin shear connector; Shown in Fig. 1 b, welded peg 7` on its frange plate; Shown in Fig. 1 c, its perforated panel 6` is two that be arranged in parallel.These two kinds of structures or its combining structure have satisfied Wavelike steel webplate preferably and concrete pushes up, the force request of base plate binding site place longitudinal shear.Yet steel web plate composite box girder is under the eccentric load effect, except that causing that the cross section rigidity is reversed, also produce cross section distortion, must produce certain bending moment in fact at Wavelike steel webplate and concrete top, place, base plate junction (promptly constituting concrete pin shear connector position), therefore the shear connector of this binding site not only will bear longitudinal shear, and will bear the pulling capacity that transverse bending moment produces.If above-mentioned two kinds of form of structure or its combining structure form do not have enough thickness at the binding site place, make its binding site place produce the transverse bending distortion easily.
Summary of the invention
Technical problems such as the utility model mainly solves case beam median ventral plate and concrete pushes up, base plate binding site place can't meet design requirement owing to be easy to generate the transverse bending distortion under the load action, and a kind of reinforcement Wavelike steel webplate shear connector is provided.
Reinforcement Wavelike steel webplate shear connector of the present utility model is realized in the following manner: it includes two ends and places Wavelike steel webplate between combined box beam concrete roof and base plate, this Wavelike steel webplate and concrete top, base plate binding site place are rigidly connected steel web surface weldable steel strip or boss at the binding site place by concrete pin shear connector formation; The width of this steel plate band or boss is 100～150mm, and thickness is 8～12mm.
Above-mentioned steel plate band or boss are welded on Wavelike steel webplate and concrete pushes up, the inboard or inside and outside both sides at base plate binding site place.
The utility model concrete pin shear connector structure is because the technological means of employing steel web and top, base plate binding site place thickening steel web, increased the shearing resistance area of the unit length inner concrete pin at this binding site place, can improve the vertical shear resistance and the horizontal bending resistance at this binding site place widely, make the shear resistance of the shear resistance of this connecting portion and steel web synchronous, and then reach the optimal design of steel web.
Description of drawings
Fig. 1 a, 1b, 1c are existing concrete pin shear connector structural representation;
Fig. 2 is a kind of embodiment schematic diagram of the present utility model.
The specific embodiment
Referring to Fig. 2, strengthening the Wavelike steel webplate shear connector in the utility model combined box beam includes two ends and places Wavelike steel webplate 1 between combined box beam concrete roof and base plate, this Wavelike steel webplate 1 and concrete top, base plate binding site place is rigidly connected by concrete pin shear connector formation, its shear connector form of structure includes the flush type shear connector, edge of a wing formula shear connector and both are in conjunction with the combined type shear connector that constitutes, its shear connector structure shown in the figure mainly is by running through Wavelike steel webplate and top, running through reinforcing bar 3 and retraining reinforcing bar 4 of base plate binding site place through hole 2 constitutes, this shear connector structure is identical with existing shear connector structure, no longer elaborates at this.Steel web surface weldable steel strip or boss 5 at the binding site place; The steel web at this binding site place general reference is connected as a single entity with the steel web and constitutes shear connector structure structure with top, base plate, can with Wavelike steel webplate integrative-structure, also perforated panel that can link to each other by frange plate or the like.The width of this steel plate band or boss 5 is 100～150mm, and thickness is 8～12mm.Figure 2 shows that the steel plate band consistent with Wavelike steel webplate; When being boss, each boss can separated by a distancely distribute.
Above-mentioned steel plate band or boss 5 are welded on Wavelike steel webplate and concrete pushes up, the inboard or inside and outside both sides at base plate binding site place, to improve the flexural strength at corrugated steel web and binding site place, shown in Figure 2, be that a side (the interior or outside) is welded with the steel plate band.
