Description
Technical field
The utility model belongs to science of bridge building field, is related to composite beam bridge, especially contains the combination beam of perforated plate connector
Bridge.
Background technology
Composite beam bridge refers to, using connector, girder steel element and armored concrete are combined into compound section cooperation
A kind of composite structure.This structure obtains increasingly because can effectively play steel and the respective advantage of concrete bi-material
It is widely applied.
The shear connector of conventional combination beam is generally shaped steel, WELDING STUDS or Conventional open-pore plate connector.Structural steel connecting member
Use at present less, at present using more be WELDING STUDS and Conventional open-pore plate connector, the construction method of WELDING STUDS at present than
More ripe, there is special construction machinery, but it is relatively complicated to construct when WELDING STUDS is more and intensive；Conventional open-pore plate connector
Easy construction is it is only necessary to perforated plate connector be welded on girder steel, weld seam is less, and bearing capacity is higher.But it is conventional
Perforated plate connector needs to wear reinforcing bar in hole, and when in hole, reinforcing bar is longer, construction is very loaded down with trivial details, at this moment has two kinds of solutions to do
Method, one kind is to be formed directly into reinforcing bar although construction is loaded down with trivial details, but in hole, reinforcing bar can be as lower floor's reinforcing bar of concrete slab；Another
Planting is to block reinforcing bar, and segmentation penetrates in hole, and construction is more convenient, but lower floor's reinforcing bar of concrete slab needs in addition to configure,
Reinforcing bar is more mixed and disorderly.
It can be seen that objectively need research and development propose a kind of combination beam with perforated plate connector, this kind of combination beam construction when not
In addition reinforcing bar in must boring a hole as Conventional open-pore plate connector it is not required that configure lower floor's reinforcing bar of concrete slab, reinforcing bar cloth
Put short and sweet.Reinforcement location, thickness of concrete cover and bar spacing etc. can easily be passed through to carry boot-shaped slotted eye simultaneously
The size of perforated panel be adjusted, eliminate setting concrete protective layer pad and bar spacing positioning in assembling reinforcement
Process, and can effectively ensure that the protective layer thickness of concrete and the uniform of bar spacing.
Utility model content
