Abstract
The utility model discloses a bridge expansion joint device which belongs to the field of the bridge expansion joint device. The end parts of two main beam with elasticity of the bridge are fixed with an end plate respectively; one side of the end plate, which is used for fixing the bridge surface is abnormity expansion joint plates in rectangular shape. The two corresponding abnormity expansion joint plates are arranged on the bridge surface at intervals. By adopting the structure of the bridge expansion joint device, the expansion and contraction of the wall plate can be satisfied by the slippage of the plate; thus, vehicles can not bump while the vehicles run on the utility model, so the life time of the bridge is prolonged.
Description
Technical field
The utility model discloses a kind of bridge expansion joint installation, belong to the bridge expansion joint installation field.
Background technology
The bridge extension joint that uses all is being profile iron supporting shrinkage joint now, because this seam is the horizontal of direction of traffic, produce the top car vehicle ' to this moment, especially the beam slab in winter stretches, transverse joint strengthens, and the top car is more serious, causes damaged vehicle, bring to a halt the initiation traffic accident, and influence the life-span of bridge.
Technology contents
The purpose of this utility model is the bridge expansion joint installation that discloses a kind of car of not running, prolongs the application life of bridge.
The utility model such as following technical scheme realize:
A kind of bridge expansion joint installation, two girder ends at the bridge with retractility are fixed an end plate respectively, on the end plate fixedly bridge floor one side be rectangular special-shaped shrinkage joint plate, the special-shaped shrinkage joint plate of two correspondences is spaced on bridge floor, its height contour with the height of bridge.
Above-mentioned a kind of bridge expansion joint installation, described special-shaped shrinkage joint plate is steel plateelement or cast steel.
Adopt the bridge expansion joint installation of this structure, satisfy the flexible of beam slab by the changing of the relative positions of plate, the vehicle ' car of can not running has in the above prolonged life-span of bridge.
Description of drawings
Fig. 1 is the vertical view of special-shaped shrinkage joint of the present utility model plate.
Fig. 2 is the utility model A-A partial sectional view.
The specific embodiment
With reference to Fig. 1, Fig. 2, the end fixed charge method end plate 5 of the girder 4 of bridge 1, by screw rod 6,7 fixing special-shaped shrinkage joint plates 2, the special-shaped shrinkage joint plate 3 corresponding with it is spaced on bridge floor on the end plate 5, and its height is contour with the height of bridge.Adopt the bridge expansion joint installation of this structure, satisfy the flexible of beam slab by the changing of the relative positions of plate, the vehicle ' car of can not running has in the above prolonged life-span of bridge.
Claims (2)
1, a kind of bridge expansion joint installation, it is characterized in that: two girder ends at the bridge with retractility are fixed an end plate respectively, on the end plate fixedly bridge floor one side be rectangular special-shaped shrinkage joint plate, the special-shaped shrinkage joint plate of two correspondences is spaced on bridge floor, and its height is contour with the height of bridge.
