Description
Technical Field
The utility model relates to a test device convenient to transportation of bridge floor continuous structure test component and hoist and mount.
Background
The jumping caused by the expansion joints of the bridge and the secondary adverse effects (such as additional internal force of the structure, corrosion of the structure caused by water leakage and the like) caused by the damage of the expansion devices are the troublesome problems which are often encountered in the actual operation of the bridge at home and abroad at present. The jumping caused by the telescopic device not only causes great impact on the bridge, but also reduces the driving comfort of drivers and passengers. In addition, with the increasing of the traffic flow, the maintenance and replacement of the expansion joint device often cause serious traffic interruption, and further generate huge economic loss. Therefore, a series of problems brought by the bridge expansion joint are inevitable. In order to fundamentally solve the problem of the telescopic device, the bridge deck simply supports the bridge in succession and comes into force. The bridge deck continuous simply-supported girder bridge is a structure which is formed by combining adjacent girders together by adopting connecting plates to form a continuous integral structure of the bridge deck and simultaneously ensures the simple support of the girders. The bridge deck continuous simply-supported beam bridge has the mechanical characteristics of the simply-supported beam bridge, and is simple in structure and convenient to construct; and the expansion device is not arranged, so that the construction, maintenance and repair cost of the expansion device is saved, the driving stability is improved, and the impact load of a driving on a bridge is reduced. Because the expansion device between the adjacent main beams is cancelled, the expansion amount of the beam body generated by temperature deformation, concrete shrinkage and creep and the like is absorbed by the connecting plate.
The connecting plate in the bridge deck continuous simply-supported girder bridge is a weak link of the structure. As for the structure, because the girder is the simple beam, the connecting plate is located the beam-ends of girder, not only will bear the longitudinal axle that girder temperature breathing deformation transmitted and warp to warp, still need bear the main girder tip rotational deformation and the concentrated power and the impact of wheel that vertical load such as car produced, the atress is complicated, and design, construction and maintenance are improper, all can cause the fracture. At present, when a domestic scholars perform test research on a bridge deck continuous structure, a bridge deck continuous structure test component is usually required to be manufactured in a special test piece manufacturing field, and the bridge deck continuous structure test component comprises two main beams and a connecting plate between the main beams. And then transporting the bridge deck continuous structure test component to a test loading field for testing. And operations such as hoisting are required in the transportation process of the bridge deck continuous structure test member. In the bridge floor continuous structure, compare with the girder, the connecting plate belongs to the weak link, appears the phenomenon of connecting plate fracture very easily because the dislocation of horizontal position or elevation position appears in two girders in transportation or hoist and mount process, leads to the experiment to continue to develop.
