Description
Technical field
This utility model belongs to technical field of bridge construction, is specifically related to a kind of bridge pad.
Background technology
In the modern times of fast pace life, the trip of people was also gradually developed into by former walking and is ridden instead of walk by the vehicles, such as automobile, train, aircraft, steamer etc..Corresponding highway, railways etc. one are that the road of class starts to occur, and in evolution gradually developed into build in the air by pavement construction.In such a situa-tion, bridge beam action the most all the more important, because in the highway of long distance is built, the place such as river to be crossed over, mountain valley, so this is will to be connected by bridge.In bridge construction, bridge pad is the important component connecting, retraining bridge upper and lower part structure, is an indispensable part for the load-bearing of bridge.At present, railway, the bearing of highway beam bridge are usually fixed pattern, because the bearing of fixed pattern can either bear horizontal load, can bear again vertical load.But owing to it is fixed structure, for displacement, displacement is the least, and the supported end of beam can not be freely rotatable, and being not allow for any flexible in the horizontal direction, bearing is easy to abrasion or the situation of cracking, after employing the most several years of more than ten years, bearing will loss of function.
Utility model content
The purpose of this utility model is to overcome the deficiencies in the prior art and provide a kind of bridge pad, and this is simple and practical, easy construction, adaptation displacement, durable in use and weight capacity is strong.
In order to achieve the above object, this utility model adopts the following technical scheme that
This utility model provides a kind of bridge pad, including upper bracket plate and lower support plate, the upper wall of upper bracket plate is connected with bridge beam body, the lower wall of lower support plate is connected with bridge pier, the both sides, lower end of described upper bracket plate are provided with convex platform, the upper end of lower support plate is provided with the lower convex platform corresponding with convex platform, space is left between surface and the surface of lower convex platform of convex platform, groove is all offered on the surface of convex platform and the surface of lower convex platform, being provided with post between the groove of the groove of convex platform lower convex platform corresponding thereto, post periphery is arranged with spring；Being provided with end basin between two lower convex platforms on lower support plate surface, the inside of end basin is embedded with rubber slab, and the surface of rubber slab is provided with the location-plate of convex spherical, and the lower end of upper bracket plate is provided with the concave spherical surface liner plate matched with location-plate.
Anchoring part is passed through in the both sides of described end basin, is correspondingly provided with Bower Anchor seat respectively at the two ends, surface of seat board of going to the bottom, is provided with drag-line between the anchoring part that Bower Anchor seat is corresponding with this Bower Anchor seat homonymy.
The upper surface of described rubber slab is less than the upper surface on basin basin edge, the end.
Compared with prior art, the beneficial effect that this utility model obtains:
1. in this utility model, the both sides, lower end of upper bracket plate are provided with convex platform, the upper end of lower support plate is provided with the lower convex platform corresponding with convex platform, space is left between surface and the surface of lower convex platform of convex platform, groove is all offered on the surface of convex platform and the surface of lower convex platform, being provided with post between the groove of the groove of convex platform lower convex platform corresponding thereto, post periphery is arranged with spring；This structure makes bearing in the case of by vertical, can carry out suitable displacement, uses elastomeric material as pressed material, improves durability and ductility so that bridge pad has more preferable bearing capacity, and service life is longer.
2. the surface of this utility model rubber slab is provided with the location-plate of convex spherical, the lower end of upper bracket plate is provided with the concave spherical surface liner plate matched with location-plate, owing to having certain roughness between location-plate and liner plate, after bridge construction completes, under the effect of external force so that location-plate and liner plate no longer occur relative movement.
3. this utility model Stability Analysis of Structures, safe and reliable, adjust easily, the suitability is strong, installs and dismantle simplicity, and compressive resistance ability is strong.
Accompanying drawing explanation
Fig. 1 is this utility model structural representation.
Detailed description of the invention
Below in conjunction with the accompanying drawings this utility model is further illustrated.
With reference to shown in Fig. 1, a kind of bridge pad, including upper bracket plate 1 and lower support plate 2, the upper wall of upper bracket plate 1 is connected with bridge beam body, the lower wall of lower support plate 2 is connected with bridge pier, the both sides, lower end of described upper bracket plate 1 are provided with convex platform 3, the upper end of lower support plate 2 is provided with the lower convex platform 4 corresponding with convex platform, space is left between surface and the surface of lower convex platform 4 of convex platform 3, groove 5 is all offered on the surface of convex platform 3 and the surface of lower convex platform 4, it is provided with post 6 between the groove of the groove of convex platform lower convex platform corresponding thereto, post 6 periphery is arranged with spring 7；Being provided with end basin 8 between two lower convex platforms on lower support plate 2 surface, anchoring part 12 is passed through in the both sides of end basin 8, is correspondingly provided with Bower Anchor seat 13 respectively at the two ends, surface of seat board of going to the bottom, is provided with drag-line 14 between the anchoring part that Bower Anchor seat is corresponding with this Bower Anchor seat homonymy；The inside of end basin 8 is embedded with rubber slab 9, and the surface of rubber slab 9 is provided with the location-plate 10 of convex spherical, and the lower end of upper bracket plate 1 is provided with the concave spherical surface liner plate 11 matched with location-plate；The upper surface of described rubber slab 9 is less than the upper surface on end basin 8 basin edge.
