Abstract
The utility model relates to a perforated steel plate connector structure for connecting a steel truss with concrete. The steel truss and concrete cooperate with each other through a shear connector. In the conventional connecting way, a toggle pin shear connecting piece is applied frequently, but limited bearing force and ductility are limited. The two longitudinal sides of the joint of a steel truss rod piece and a concrete beam are provided with steel truss gusset plates respectively; the steel truss gusset plates are provided with openings; in the openings in both sides, penetration steel bars are arranged and concrete is poured. The connector structure related to the utility model is a PBL key, and has the advantages of greater limited bearing force, high ductility, great deformation before damage, non-brittle damage and excellent fatigue resistance in comparison to an ordinary shear connecting piece.
Description
Technical field
the utility model belongs to railroad bridge construction technique field, is specifically related to a kind of connection steel purlin and concrete open pore steel plate connecting key structure.
Background technology
The structure that concrete beam and steel purlin combine has improved the span ability of concrete bridge, also fully retained that concrete beam rigidity is large, power performance good, economic dispatch advantage, be particularly suitable for high-speed railway bridge requirement, in railway construction in China, be widely applied.In the node of concrete beam and the combination of steel purlin, comprise concrete and steel bi-material, there is interaction in the two, belongs to steel-concrete combined joint.Steel purlin and concrete connected mode are that implementation structure member is connected the hinge with power transmission, are the keys that guarantees integrality performance of the structure.
Steel purlin is connected to realize collaborative work with concrete by shear connector, and in traditional connected mode, applying more is peg shear connector, and peg shear connector is a kind of flexible connecting member, and its bearing capacity is lower, and it is poor that antiskid moves ability.Along with research with application go deep into, steel purlin and concrete connected mode that some are novel continue to bring out.
Summary of the invention
The purpose of this utility model is to provide a kind of connection steel purlin and concrete open pore steel plate connecting key structure of effective raising bearing capacity.
The technical scheme that the utility model adopts is:
Connection steel purlin and a concrete open pore steel plate connecting key structure, include steel boom part and concrete beam, it is characterized in that:
Longitudinal both sides in the junction of steel boom part and concrete beam arrange respectively steel purlin gusset plate, on the gusset plate of steel purlin, perforate are set, and in bilateral perforate, arrange and run through reinforcing bar concrete perfusion.
Described perforate is provided with two rows.
The utlity model has following advantage:
The related connecting key structure of the utility model is a kind of PBL key, compares common shear connector, and it is high a lot of that its ultimate bearing capacity is wanted, and ductility is good, has larger distortion before destruction, is non-brittle destruction, and anti-fatigue performance is excellent.
Accompanying drawing explanation
Fig. 1 is the utility model elevational schematic view.
Fig. 2 is the vertical cross sectional representation of the utility model.
In figure, 1-steel boom part, 2-concrete beam, 3-steel purlin gusset plate, 4-perforate, 5-runs through reinforcing bar.
The specific embodiment
Below in conjunction with the specific embodiment, the utility model is described in detail.
A kind of connection steel purlin that the utility model relates to and concrete open pore steel plate connecting key structure, that a kind of PBL shear connector connects, than other traditional steel purlin and concrete connected mode, PBL key has the advantages such as bearing capacity is large, ductility good, anti-fatigue performance is excellent, for steel purlin and concrete connection provide a kind of new selection.The utility model arranges respectively steel purlin gusset plate 3 in steel boom part 1 and longitudinal both sides of the junction of concrete beam 2, on steel purlin gusset plate 3, perforate 4 is set, and perforate 4 is provided with two rows, arranges and run through reinforcing bar 5 concrete perfusion in bilateral perforate 4.Perforate size, on the one hand according to calculative determination, also needs to consider concrete grain composition size on the other hand, guarantees the concrete compactness of pre-buried position of joints, finally reaches the effect by reinforcing bar is resisted shear flow jointly in concrete and hole.
It is cited that content of the present utility model is not limited to embodiment, and the conversion of any equivalence that those of ordinary skills take technical solutions of the utility model by reading the utility model manual, is claim of the present utility model and contains.
