Abstract
The utility model provides a plate type rubber support seat which is characterized by comprising a plurality of middle steel plates. Middle rubber layers are arranged between the middle steel plates, face adhesives are arranged on upper end faces and lower end faces of the middle steel plate, lateral protection layers are arranged on the lateral edge of the middle steel plates, and the thickness of each lateral protection layer is 5 millimeters. The plate type rubber support seat for a highway bridge is of a novel structure, the lateral protection layers with the thickness of 5 millimeters improve flexibility and aging resistance of rubber materials, and the problems that middle rubber layers of the plate type rubber support seat are prone to protrude and crack are solved.
Description
Technical field
The utility model relates to the bridge technology field, specifically is a kind of economical and practical laminated rubber bearing.
Background technology
The highway in China bridge plate-type rubber support adopts national standard and transportation industry standard to design and produce at present; in use the reason owing to design and installation tends to make laminated rubber bearing the phenomenon of intermediate rubber layer evagination to occur; this phenomenon so that laminated rubber bearing in use the lateral protection layer stress occurs and concentrate, be full of cracks easily appears in the aging lateral protection layer that makes that has accelerated the lateral protection layer.Affect the application life of laminated rubber bearing and the aesthetic feeling of outward appearance, increased the difficulty of installing.
The highway in China bridge plate-type rubber support following shortcoming in use easily occurs in the situation that properties meets relevant criterion at present: the intermediate rubber layer evagination of (1) hoop; (2) local intermediate rubber layer evagination; This phenomenon has affected laminated rubber bearing outward appearance and application life in use, therefore need to be improved.
The utility model content
The purpose of this utility model is to provide a kind of laminated rubber bearing at this, from satisfying the functional performance of laminated rubber bearing, simplifies installation difficulty and sets out, and guarantees the properties of laminated rubber bearing and simplifies installation difficulty; Reduce the intermediate rubber layer evagination appears in laminated rubber bearing in installation process phenomenon under the front topic of relevant criterion satisfying, simplified installation process.
The utility model is achieved in that a kind of laminated rubber bearing of structure, it is characterized in that: be provided with a plurality of middle steel plates; it is intermediate rubber layer between the described middle steel plate; middle steel plate up and down both ends of the surface is face glue, and the middle steel plate side is the lateral protection layer, and described lateral protection layer thickness is 5 millimeters.
The intermediate rubber layer evagination that in installing and using process, occurs for slab rubber bearing in Highway Bridge; we improve this phenomenon by improvement too fast appearance aging cracking problem, 5 millimeters lateral protection layer thicknesses that increase slab rubber bearing in Highway Bridge with the side tensile stress that reduces laminated rubber bearing middle steel plate when the pressurized and produce on the impact in shape of side topping.
Take the product of GYZ300 * 63 as example, laminated rubber bearing is tested at 500 tons of pressure testing machines, and the force value when the intermediate rubber evagination occurs has improved 2 MPa.Laminated rubber bearing is subjected to vertical pressure the phenomenon of intermediate rubber layer evagination can occur when 6MPa and just this phenomenon can occurs now will be at 8MPa the time before that is to say.Increase material cost less than in 5% the situation, supporting capacity has improved more than 30%, the difficulty when having improved greatly laminated rubber bearing performance in use and having simplified installation by improving
The beneficial effects of the utility model are: the utility model provides a kind of slab rubber bearing in Highway Bridge of new construction by improvement; by increasing by 5 millimeters lateral protection layer thickness, and improve the anti-ageing properties of subduing of sizing material to improve laminated rubber bearing intermediate rubber layer evagination and the phenomenon of be full of cracks to occur.

Among the figure: 1, face glue, 2, middle steel plate, 3, intermediate rubber layer, 4, the lateral protection layer.
The specific embodiment
Be described in detail below in conjunction with 1 pair of the utility model of accompanying drawing:
The utility model provides a kind of laminated rubber bearing by improving at this; as shown in the figure: be provided with a plurality of middle steel plates 2; be intermediate rubber layer 3 between the described middle steel plate 2; middle steel plate about in the of 2 both ends of the surface be face glue 1; middle steel plate 2 sides are lateral protection layer 4; described lateral protection layer 4 thickness are 5 millimeters, the lateral protection layer thickness (5 millimeters) that increases slab rubber bearing in Highway Bridge with the side tensile stress that reduces laminated rubber bearing middle steel plate when the pressurized and produce on the impact in shape of side topping.Intermediate rubber layer 3, both ends of the surface are that face glue 1, lateral protection layer 4 forms integrative-structures up and down.Take the product of GYZ300 * 63 as example, laminated rubber bearing is tested at 500 tons of pressure testing machines, and the force value when the intermediate rubber evagination occurs has improved 2 MPa.Laminated rubber bearing is subjected to vertical pressure the phenomenon of intermediate rubber layer evagination can occur when 6MPa and just this phenomenon can occurs now will be at 8MPa the time before that is to say.Increase material cost less than in 5% the situation, supporting capacity has improved more than 30%, the difficulty when having improved greatly laminated rubber bearing performance in use and having simplified installation by improving.
