Description
Technical field
The experimental rig and method that the present invention relates to a kind of to transport and lift convenient for bridge floor continuous structure test component.
Background technique
Jump brought by bridge expanssion joint vehicle and due to telescopic device damage the secondary adverse effect of bring (such as structure it is attached
Add internal force, leak to corrosion of structure etc.) it is the thorny problem that current domestic and abroad bridge is frequently encountered in actual operations.By
The jump vehicle caused by telescopic device not only causes very big percussion to bridge, but also can reduce the driving of driver and passenger
Comfort level.In addition, maintenance and replacement to expansion gap device often will cause serious friendship with the increasingly increase of the magnitude of traffic flow
It is logical to interrupt, and then generate huge economic loss.It can be seen that solving bridge expanssion joint bring a series of problems has been that gesture exists
It must go.In order to fundamentally solve the problems, such as that telescopic device, the continuous freely-supported bridge of bridge floor come into being.Bridge floor continuous freely supported beam bridge
It is that a kind of be combined together adjacent girder by using connecting plate becomes the continuous overall structure of bridge floor, while guaranteeing again
The structure of its girder freely-supported.Bridge floor continuous freely supported beam bridge had both had the mechanical characteristic of simply supported girder bridge, and simple structure is easy for construction；
There is no telescopic device again, save telescopic device construction, maintenance and maintenance cost, improve driving stationarity, lowers driving to bridge
Impact load.Due to eliminating the telescopic device between adjacent girder, beam body is due to temperature deformation, concrete shrinkage and creep etc.
The stroke of generation is absorbed by connecting plate.
Connecting plate in bridge floor continuous freely supported beam bridge is the weak link of structure.Itself with regard to structure, since girder is
Simply supported beam, connecting plate are located at the beam-ends of girder, not only to bear girder temperature movement displacement transfer and the vertical bridge that comes is to deformation, also
It bears the end of main beam rotational deformation of the vertical loads such as automobile generation and the concentrated force and percussion of wheel, stress is multiple
Miscellaneous, it is improper to design, construct and conserve, and can cause to crack.Currently, domestic scholars carry out experimental study to bridge floor continuous structure
When, it usually needs bridge floor continuous structure test component, including two blocks of girders and girder are made in special test specimen production place
Between connecting plate.Then bridge floor continuous structure test component is transported to test load place and carries out test.It is continuous in bridge floor
It carries out the operation such as lifting during structural test component conveying.In bridge floor continuous structure, compared with girder, connecting plate category
In weak link, it is easy to since two girders the changing of the relative positions of horizontal position or elevation location occur and go out in transport or hoisting process
The phenomenon that existing connecting plate cracking, cause test that can not carry on.
