Abstract
The utility model discloses a variable-stiffness plate rubber support, which comprises a rubber protecting layer, surface adhesive, intermediate rubber, an intermediate steel plate I and an intermediate steel plate II. The rubber protecting layer is arranged on the periphery of the surface adhesive; the intermediate rubber, the intermediate steel plate I and the intermediate steel plate II are arranged in the surface adhesive; and the intermediate steel plate I and the intermediate steel plate II are arranged at intervals. The variable-stiffness plate rubber support is simple in structure, convenient in operation, economical and practical, has higher economic and social benefits, and is capable of changing the stiffness of a whole bridge pier, jointly participating in vibration absorption and isolation and greatly reducing bridge construction cost.
Description
Technical field
The utility model belongs to bridge support technology field, is specifically related to a kind of New-type plate neoprene bearing.
Background technology
Common laminated rubber bearing adopts thickness even, and the middle steel plate of planar dimension unanimity carries out processing and manufacturing, and its shear modulus is 1.The common laminated rubber bearing of highway in China bridge employing at present mainly contains following shortcoming: 1, the laminated rubber bearing of selecting for use according to industry standard, owing to its horizontal rigidity is not done designing requirement, therefore can't calculate and detect the needs whether its horizontal rigidity satisfies bridge construction.And in the bearing of specifications and models of the same race, its horizontal rigidity is constant, can't allow the user select flexibly when design like this.2, original laminated rubber bearing all is to adopt single bearing when installing and using, and can't carry out being used in combination of rigidity, can't rationally select for use when design like this.3, because the most of bridge of China when adopting laminated rubber bearing, is all selected for use according to industry standard, do not consider that the horizontal rigidity of bridge pier influences bridge construction application life, or adapt to the needs of bridge construction by the rigidity that changes bridge pier.Therefore when the bridge pier height size of bridge was inconsistent, the rigidity of each bridge pier will be different, and the bridge pier height is high more, and its rigidity is more little.If adopt common laminated rubber bearing, the horizontal rigidity of each stress point in the then whole bridge system is inconsistent.In service at bridge will produce part bridge pier participation work, and another part bridge pier does not participate in the situation of work, and is totally unfavorable to the use and the life-span of bridge construction like this.
The utility model content
The purpose of this utility model is to overcome above-mentioned deficiency, and a kind of change rigidity neoprene bearing is provided, and this bearing can effectively improve the safe operation and the requirement in application life of bridge, make simultaneously bridge operation or during earthquake each bridge pier stressed evenly.
For achieving the above object; the technical scheme that the utility model adopted is: a kind of change rigidity laminated rubber bearing; form by rubber cover, face glue, intermediate rubber, middle steel plate I and middle steel plate II; it is characterized in that: described rubber cover is arranged on around the face glue; be provided with intermediate rubber, middle steel plate I and middle steel plate II in the face glue, described middle steel plate I and middle steel plate II are arranged at interval.Fill intermediate rubber between described middle steel plate I and the middle steel plate II.
Intermediate rubber described in the utility model, middle steel plate I and middle steel plate II are embedded in face glue inside, and the length of middle steel plate II is longer than middle steel plate I.
The utility model is by the appearance and size of adjusting laminated rubber bearing bosom steel plate and optimization of C (changing the mechanical property of rubber), reaches the purpose of adjusting the bearing horizontal rigidity.Because the horizontal rigidity of bearing is relevant with the constraint of the mechanical property of rubber and steel plate, therefore can be by the steel plate of combination different size and different prescriptions, on the bearing of same size, obtain multiple horizontal rigidity, and in order to design the convenience of selecting for use and constructing, can design the laminated rubber bearing of different-stiffness, and these bearings are made up mutually, satisfying the demand of bridge different-stiffness, and improve the seismic fortification intensity of bridge.Because the rigidity of this neoprene bearing can be adjusted, therefore can reach the purpose that makes all bridge piers all stressed by adopting the bearing of different-stiffness, when earthquake, can make the total fellowship subtract shock insulation work.Simultaneously, adopt change rigidity laminated rubber bearing to change the horizontal rigidity of bridge system than practical more economically by the rigidity that changes bridge pier.
Therefore the utlity model has rigidity simple in structure, easy to operate, as to change whole bridge pier, fellowship subtracts shock insulation, greatly reduces the bridge construction construction cost, and is economical and practical, and high economic benefit and social benefit are arranged.
Description of drawings
Fig. 1 is the utility model structural representation
Among the figure: the 1-rubber cover; 2-face glue; The 3-intermediate rubber; 4-middle steel plate I; 5-middle steel plate II.
The specific embodiment
Below in conjunction with accompanying drawing the technical solution of the utility model is done detailed description:
As shown in Figure 1: become the rigidity laminated rubber bearing, form by rubber cover 1, face glue 2, intermediate rubber 3, middle steel plate I 4 and middle steel plate II 5.Described rubber cover 1 is arranged on around the face glue 2, is provided with intermediate rubber 3, middle steel plate I 4 and middle steel plate II 5 in the face glue 2.Described middle steel plate I 4 and middle steel plate II 5 are arranged at interval, and filling intermediate rubber 3 between middle steel plate I 4 and the middle steel plate II 5, and the length of middle steel plate II 5 is longer than middle steel plate I 4.
Described intermediate rubber 3, middle steel plate I 4 and middle steel plate II 5 are embedded in face glue 2 inside.
The utility model middle steel plate I 4 also can be longer than middle steel plate II 5, can adjust the rigidity of this neoprene bearing by the dimension scale of adjusting middle steel plate I and middle steel plate II simultaneously, thereby reach the demand of bridge rigidity and make all stressed effect of each bridge pier of bridge.Therefore protection domain of the present utility model is not limited in above embodiment, these innovation and creation is made be equal to replacement or do not make substantial improvements also within the protection domain of the invention.
