Abstract
The utility model relates to a bridge expansion joint device which belongs to the field of the bridge expansion joint device. An end plate is respectively fixed to end parts of two main beam of the bridge, and each main beam has the elasticity. Supporting brackets are fixed on the end plates, wedge-shaped expansion joint plates are installed on the supporting brackets, and the two corresponding expansion joint plates are consistent with each other to form a wedge-shaped joint in straight and sloping assembly. By the structure of the utility model, the bumping phenomena of vehicles can not be generated while the vehicles run on the utility model; thus, 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 and to cause traffic accident easily, and influence the life-span of bridge.
Technology contents
The purpose of this utility model is to disclose the bridge expansion joint installation that a kind of do not run car, vertical masonry joint and R-joining combine.
The utility model such as following technical scheme realize:
A kind of bridge expansion joint installation, two girder ends that have retractility at bridge are fixed an end plate respectively, fixing support rack on the end plate, wedge shape shrinkage joint plate is housed on the bracing frame, the shrinkage joint plate of two correspondences matches, and forms key joint straight, that tiltedly make up, and its height is contour with the height of bridge.
Above-mentioned a kind of bridge expansion joint installation, described wedge shape shrinkage joint plate is malleable iron foundry goods or steel plate or steel concrete.
Adopt the bridge expansion joint installation of this structure, 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 wedge shape of the present utility model shrinkage joint plate.
Fig. 2 is the utility model A-A partial sectional view.
The specific embodiment
With reference to Fig. 1, Fig. 2, the wedge shape shrinkage joint plate 2,3 of bridge 1 is corresponding, forms key joint straight, that tiltedly make up, and its height is contour with the height of bridge.At the end fixed charge method end plate 5 of the bridge 4 with retractility, by screw rod 81,82 fixing support racks 6, by screw rod 83 stationary wedge shrinkage joint plates 2, wedge shape shrinkage joint plate is malleable iron foundry goods or steel plate or steel concrete on the bracing frame 6 on the end plate.
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, fixing support rack on the end plate, wedge shape shrinkage joint plate is housed on the bracing frame, the shrinkage joint plate of two correspondences matches, form key joint straight, that tiltedly make up, its height is contour with the height of bridge.
