Abstract
The utility model belongs to the technical field of bridge supports and particularly relates to a steel support with double curved cylindrical surfaces. The steel support is mainly and technically characterized in that the steel support comprises an upper seat plate, a middle steel lining plate and a lower seat plate, the upper surface and the lower surface of the middle steel lining plate are an upper convex cylindrical surface and a lower convex cylindrical surface onto which stainless steel plates are attached, the bottom surface of the upper seat plate is an upper concave cylindrical surface onto which a wear-resistant sliding plate is attached and which is matched with the upper convex cylindrical surface. The top surface of the lower seat plate is a lower concave cylindrical surface onto which a wear-resistant sliding plate is attached and which is matched with the lower convex cylindrical surface. The axis of the upper convex cylindrical surface is perpendicular to the axis of the lower convex cylindrical surface. The steel support with double curved cylindrical surfaces has the advantages that the structure is simple, since a longitudinal turning angle and a transverse turning angle are separated from each other, the need of bridge displacement can be completed in the axial directions of the cylindrical surfaces and turning angles produced by a bridge body can be effectively met. The steel support with double curved cylindrical surfaces can be widely used for all kinds of bridge works.
Description
Technical field
The utility model belongs to the bridge pad technical field, relates in particular to a kind of hyperbolic cylinder steel support.
Background technology
In bridge design, bearing is as critical piece, and its Load Transfer of bearing bridge top is given substructure, and satisfies the needs of the rotation and the displacement of superstructure.At present, because most Column face bearings are single-column face bearing, can only satisfy vertical corner function, can't satisfy horizontal corner, this bearing only is fit to the single line bridge to be used, and some Column face bearing is provided with two cylinder bodies, satisfied the vertical, horizontal corner, but its complex structure, cost increases considerably, and its economic worth is little.
The utility model content
The technical problems to be solved in the utility model just provides a kind of simple in structure, can satisfy the hyperbolic cylinder steel support of vertical, horizontal corner simultaneously.
For solving the problems of the technologies described above, the technical solution adopted in the utility model is: comprise upper base plate, middle steel liner plate, following seat board, the upper and lower surfaces of steel liner plate are epirelief cylinder and the following projection face that is pasted with corrosion resistant plate in the middle of described, the bottom surface of upper base plate is the fovea superior cylinder that is pasted with wear-resisting slide plate and is complementary with the epirelief cylinder, the end face of following seat board is the recessed cylinder that is pasted with wear-resisting slide plate and is complementary with following projection face, and the axis of epirelief cylinder and following projection face is perpendicular.
Its additional technical feature is: the axis of described epirelief cylinder and following projection face is perpendicular.
Hyperbolic cylinder steel support provided by the utility model, compared with prior art, the top and bottom of middle steel liner plate are the epirelief cylinder and the following projection face structure of two axis normal, epirelief cylinder, following projection face cooperate with the fovea superior cylinder of upper base plate, the recessed cylinder of following seat board respectively, can satisfy the needs of vertical, horizontal corner simultaneously, and one of them cylinder be engaged in also can satisfy when satisfying corner displacement requirement.Hyperbolic cylinder steel support provided by the utility model, vertically corner and horizontal corner are separated, structure with the hyperbolic cylinder panel has solved corner and displacement problem, finish the corner that effectively satisfies the generation of beam body when the bridge displacement is wanted with the cylinder axial direction, can be widely used in all bridge engineering.It is simple in structure, and cost is controlled, effectively raises its economic worth.
Description of drawings
Fig. 1 is the utility model hyperbolic cylinder steel support structural representation along the bridge;
Fig. 2 is the structural representation of hyperbolic cylinder steel support cross-bridges direction.
The specific embodiment
Be described further below in conjunction with the structure and the principle of the drawings and specific embodiments hyperbolic cylinder steel support provided by the utility model.
As shown in Figure 1, the utility model hyperbolic cylinder steel support comprises upper base plate 1, middle steel liner plate 2, following seat board 3, the top of middle steel liner plate 2 is the epirelief cylinder 4 that is pasted with corrosion resistant plate, and the bottom surface of upper base plate 1 is the fovea superior cylinder 5 that is pasted with wear-resisting slide plate and is complementary with epirelief cylinder 4.As shown in Figure 2, the hyperbolic cylinder steel support comprises upper base plate 1, middle steel liner plate 2, following seat board 3, the following of middle steel liner plate 2 is the following projection face 6 that is pasted with corrosion resistant plate, and the end face of following seat board 3 is the recessed cylinder 7 that is pasted with wear-resisting slide plate and is complementary with following projection face 6.The axis of epirelief cylinder 4 and following projection face 6 is vertical mutually.
During the utility model hyperbolic cylinder steel support uses, the epirelief cylinder 4 that is pasted with corrosion resistant plate forms a pair of arc friction pair with the fovea superior cylinder 5 that is pasted with wear-resisting slide plate, this can satisfy the corner that direction across bridge occurs to friction pair, and cylinder slippage project organization can satisfy along bridge to the displacement that produces bearing.The following projection face 6 that is pasted with corrosion resistant plate forms another to the arc friction pair with the recessed cylinder 7 that is pasted with wear-resisting slide plate, this can satisfy along bridge to the corner that occurs friction pair, and cylinder slippage project organization makes bearing can satisfy the displacement that direction across bridge produces.
Claims (2)
1. hyperbolic cylinder steel support, comprise upper base plate, middle steel liner plate, following seat board, it is characterized in that: the upper and lower surfaces of steel liner plate are epirelief cylinder and the following projection face that is pasted with corrosion resistant plate in the middle of described, the bottom surface of upper base plate is the fovea superior cylinder that is pasted with wear-resisting slide plate and is complementary with the epirelief cylinder, and the end face of following seat board is the recessed cylinder that is pasted with wear-resisting slide plate and is complementary with following projection face.
2. hyperbolic cylinder steel support according to claim 1 is characterized in that: the axis of described epirelief cylinder and following projection face is perpendicular.
