Abstract
The utility model relates to a support sliding plate for a bridge construction, which comprises a rubber layer and a polytetrafluoroethylene layer arranged on the rubber layer. A metal net rack is arranged inside the rubber layer. The support sliding plate is composed of the rubber layer with the internal metal net rack and the polytetrafluoroethylene layer arranged on the rubber layer by the aid of certain technical method in an organically integrated manner. When the support sliding plate is used, since the metal net rack consists of small irregular multidirectional units, all small units jointly bear an external load by the aid of mutual action such as elastic deformation, extrusion, friction and the like, and absorb energy when external force acts on an elastic piece of the metal net rack. The rubber layer permeates to the metal net rack, accordingly, improves elastic performance of the sliding plate and simultaneously prevents the metal net rack from being corroded. The polytetrafluoroethylene layer in the sliding plate functions in friction reduction.
Description
Technical field
The utility model relates to a kind of bridge construction support sliding plate.
Background technology
Highway, railway, urban track traffic bridge pad slide plate are made by polytetrafluoroethylene (PTFE) or modified ultra-high molecular weight polyethylene at present, utilize performances such as the two friction factor is little, abrasion performance, mainly play the anti-attrition effect in bearing.The advantage of polytetrafluoroethylmaterial material is that friction factor is little, and is wear-resisting, and shortcoming is that permissible stress is low, and the unit area bearing capacity is little; Modified ultra-high molecular weight polyethylene unit area bearing capacity ratio polytetrafluoroethylmaterial material is big, but its self-lubricating property is poor, and the phenomenon of adsorpting lubrication fat is arranged, and needs to add silicone grease after use a period of time, brings difficulty for the later maintenance of bearing.
Because the development of high-speed railway, the ratio that bridge accounts for the railway length overall increases greatly, quickening along with the train speed on the railroad bridge, continuing to increase of railroad bridge load, these all propose more and more high request to the bearing of supporting bridge, and support sliding plate then is the critical piece that influences the bearing functional performance.
The utility model content
Technical problem to be solved in the utility model provides a kind of bridge pad slide plate that integrates multiple performances such as self-lubricating, vibration damping, compressive strength height, creep be little.
The utility model adopts following technical scheme:
The utility model is made of rubber layer and the polytetrafluoroethylene floor that is arranged on the rubber layer, is provided with metal truss in the described rubber layer.
The utility model is provided with oil storage grooves at the polytetrafluoroethylene (PTFE) laminar surface.
Be provided with two-layer or two-layer above metal truss in the utility model rubber layer.
Good effect of the present utility model is as follows:
The utility model is made up of by certain process combination the rubber layer of built-in metal rack and polytetrafluoroethylene floor three parts that are arranged on the rubber layer.When the utility model uses as support sliding plate, because metal truss is a kind of irregular multidirectional junior unit, when external force acts on the metal truss elastic body, bear external loads jointly and absorb energy by interactions such as elastic deformation, extruding, frictions between each junior unit.The rubber layer infiltration has increased the elastic performance of slide plate on metal truss, protect metal truss to avoid corrosion simultaneously.Polytetrafluoroethylene floor plays antifriction function in the utility model slide plate.
The utility model is by bonding and inlay acting in conjunction and polytetrafluoroethylene floor is fixed on is built-in with on the elastomeric rubber layer of metal truss, solved the combine difficult problem of polytetrafluoroethylene (PTFE) with metal material, reduced the thickness of pure polytetrafluoroethylene floor in the slide plate, thereby reduced the creep properties of slide plate, improved the compressive strength of slide plate.
Metal-rubber slide plate of the present utility model is compared with existing support sliding plate, has advantages such as compressive strength height, the deformation of creep is little, damping property is good.The utility model has improved the compressive strength of support sliding plate, can reduce the size of bridge pad, reaches to save the bearing rolled steel dosage, reduces the purpose of bearing cost.
The utility model is filled rubber in the space of metal mesh shaped structural metal rack, forms the rubber layer of built-in metal rack, makes the utility model become a kind of supporting capacity and the new type slide plate of elastic performance between metal and rubber.
The utility model is that metal truss and three kinds of materials of rubber organically combine with polytetrafluoroethylene (PTFE), metal mesh shaped structure, make a kind of novel bridge pad slide plate, under the situation that does not reduce the slide plate self-lubricating property, improved compressive strength, elastic performance and the creep-resistant property of slide plate.The utility model friction factor is 0.0028 (standard≤0.012), the average line rate of wear is 5.5 μ m/km (standards≤15 μ m/km), and compressive strength 60MPa (standard 45MPa) all is better than the relevant requirements of " the provisional technical condition of special line for passenger trains bridge basin-type rubber support " and " the provisional technical condition supplementary provisions of Passenger dedicated railway Bridge pot rubber bearing ".

In the accompanying drawings, 1 rubber layer, 2 polytetrafluoroethylene floors, 3 metal trusses, 4 oil storage grooves
The specific embodiment
Shown in accompanying drawing 1,2,3, be a specific embodiment of the present utility model, it is made of rubber layer 1 and the polytetrafluoroethylene floor 2 that is arranged on the rubber layer 1, is provided with metal truss 3 in the described rubber layer 1.The utility model is provided with oil storage grooves 4 on polytetrafluoroethylene floor 2 surfaces.Be provided with two-layer or two-layer above metal truss 3 in the utility model rubber layer 1, the wire lath that it is good that described metal truss 3 can adopt braiding is formed by stacking or folding making.
The utility model is made up of by certain process combination the rubber layer 1 of built-in metal rack 3 and polytetrafluoroethylene floor 2 three parts that are arranged on the rubber layer 1.Metal truss 3 is a kind of irregular multidirectional junior units, when external force acts on metal truss 3 elastic bodys, bears external loads jointly and absorbs energy by interactions such as elastic deformation, extruding, frictions between each junior unit.Rubber layer 1 infiltration has increased the elastic shock attenuation performance of slide plate on metal truss 3, protect metal truss 3 to avoid corrosion simultaneously.2 antifriction functions of polytetrafluoroethylene floor.
The utility model is by bonding and inlay acting in conjunction and polytetrafluoroethylene floor 2 is fixed on is built-in with on the metal truss 3 elastomeric rubber layers 1, solved the combine difficult problem of polytetrafluoroethylene (PTFE) with metal material, reduced the thickness of the pure polytetrafluoroethylene floor 2 of slide plate, thereby reduced the creep properties of slide plate, improved the compressive strength of slide plate.
The utility model bridge may further comprise the steps with the making of support sliding plate:
1, the preparation of metal net shaped elastic body bottom: earlier metal wire knitted is become even, isotropic stereoscopic grid, applying certain pressure then, just to form metal truss 3 be metal net shaped elastic body bottom.
