Abstract
The invention provides a super-wear-resistant rubber slider for a bridge bearing, belonging to the technical field of building elements. The rubber slider comprises a slider body, wherein the slider body is rectangular, cubic or disc-shaped and is made from modified ultrahigh molecular weight polyethylene (UHMWPE); and the thickness of the slider body is 1-3mm. The rubber slider has the following beneficial effects: the slider body of single structure is made from the modified UHMWPE, so the structure of the rubber slider is simplified and the rubber slider has excellent wear resistance and low coefficient of friction resistance, is convenient to manufacture and use and is economical.
Description
Technical field
The invention belongs to the building member technical field, be specifically related to the ultra-wearable rubber slide block that a kind of bridge pad is used.
Background technology
As is known in the industry, on the building of railway bridge, road bridge, river course bridge, city high bridge bridge, the built on stilts light rail in city and various aerial constructions, all need use bridge pad, play effects such as antidetonation vibration damping by bridge pad.And all supporting antifriction plate or the damping body that the industry habitual definition is arranged of bridge pad, can be to this by the confirmations such as Chinese patent notice of authorization CN2646197Y, CN2646198Y, CN201362818Y, CN201627140U, CN201722967U and CN2403813Y that are not limited to.
With regard to the self structure of aforesaid antifriction plate, done introduction at CN101492906B and CN101892630A, wherein CN101492906B is designed to three layer construction with the antifriction plate, two-layer up and down polytetrafluoroethylene (PTFE) and the intermediate layer of being then is modified Teflon, though this patent scheme can embody the strong point that coefficient of friction alleged in its manual is low, supporting capacity is high, creep is little and compressive strain is little, structure relative complex and manufacture difficulty are big to be its shortcoming.
Summary of the invention
Task of the present invention be to provide a kind of simple in structure, have that excellent abrasive, mill resistance coefficient are little, ultra-wearable rubber slide block that manufacturing and bridge pad easy to use are used.
Task of the present invention is finished like this, and the ultra-wearable rubber slide block that a kind of bridge pad is used comprises the slide block body, and this slide block body is made for the shape of cuboid, square or disc by modified ultra-high molecular weight polyethylene, and thickness is 1-3 ㎜.
Slide block body of the present invention has pit towards the surface distributed of a last side.
Pit of the present invention is distributed in the surface of described slide block body towards a last side with intensive form.
Pit of the present invention is a semicircular recess.
Technical scheme provided by the invention is made the slide block body of single structure by modified ultra-high molecular weight polyethylene, thereby makes structure obtain simplifying, and have that excellent abrasive, the coefficient of friction resistance are little, manufacturing and easy to use and embody economy.
Description of drawings
Fig. 1 is the embodiments of the invention structure chart.
Fig. 2 is an application examples schematic diagram of the present invention.
The specific embodiment
Embodiment 1:
Ask for an interview Fig. 1, provided the slide block body of making by modified ultra-high molecular weight polyethylene (UHMW-PE) 1, this slide block body 1 be shaped as cuboid (being cuboid), thickness is 1 ㎜, with present location status shown in Figure 1 is example, this slide block body 1 towards on the surface of a side be distributed with pit 11 with intensive form, pit 11 is preferably semicircular recess, the effect of pit 11 plays oil storage, so that further reduce friction factor.
Embodiment 2:
Change the shape of slide block body 1 into square, thickness changes 2 ㎜ into, and all the other are all with the description to embodiment 1.
Embodiment 3:
Change the shape of slide block body 1 into disc, thickness changes 3 ㎜ into, and all the other are all with the description to embodiment 1.
Although the applicant is not subjected to the restriction of three shapes that embodiment lifts with three kinds of difformities that three embodiment have explained slide block body 1.
Application examples:
Asking for an interview Fig. 2, provided neoprene bearing 2 in Fig. 2, the slide block body 1 of embodiment 1,2 or 3 is incorporated into a side surface of neoprene bearing 2, specifically is to adopt vulcanization that one side surface of neoprene bearing 2 is combined with slide block body 1 of the present invention.Because slide block body 1 is to be done by ultrahigh molecular weight polyethylene, therefore need not to use bonding adhesive and directly at high temperature slide block body 1 is vulcanized with neoprene bearing 2 and combine, because slide block body 1 has desirable affinity with neoprene bearing 2, so can conveniently reliably become with neoprene bearing 2.In addition, slide block body 1 provided by the invention has the bearing capacity that obviously is better than the lance tetrafluoroethene, thereby under the situation of equal bearing capacity, can reduce the area of slide block body 1, not only has the low and strong shock resistance of friction factor, and have the good strong point of sliding, can change as required for color in addition.
In sum, slide block body 1 provided by the invention is except the characteristics with board-like bearing, can also satisfy the needs of bridge pad counter-force for the bigger bridge of middle or small tonnage horizontal movement, be not only applicable to the freely-supported bridge of large span, and be applicable to continuous bridge, the slide block that can be used as in addition in the bridge incremental launching construction uses, and even can be applicable to the slippage carrier of main equipment.
