Description
Technical field
The utility model relates to a kind of supporting bridge device.
Background technology
Bridge pad is to be set up on pier, platform, the device of end face supporting bridge superstructure, its effect be by smooth and easy the load of superstructure, be delivered to bridge pier safely, platform gets on, ensure that superstructure realizes the distortion of expected design under the factor effects such as load, variations in temperature, solidifying soil shrink, creep, so that the actual loading situation of structure meets rated figure simultaneously; Be the key link that ensures bridge force-bearing safety and normal usage energy thereof, himself power transmission reliability and durability are most important.For different construction and service condition, bridge pad is except facing material natural aging, and by the impact of hazardous substances, the erosion of marine environment chlorine particle, water impact and object strikes etc. in reply dust, ultraviolet ray, atmosphere, its durability is caused to adverse effect.
Bridge engineering circle is reply bridge pad endurance issues, and prior art generally solves by two kinds of modes.
Improve the material property of bearing own, thereby increase its overall application life, such as coastal area employing weathering steel bearing, bearing adopt the rubber product that anti-aging degree is higher etc., and this kind of mode will cause bearing cost to improve a lot.
By strengthening inspection and the maintenance to bearing, if desired the bearing of durability deficiency is more brought to the normal usage energy that ensures bridge." Urban Bridge maintenance technology specification " (CJJ-99-2003), " highway bridge and culvert Maintenance specification " (H.04.JTGH11-2004) all have inspection, maintenance and the replacing of special chapters and sections to bridge pad to propose specific requirement.Bearing inspection and maintenance need spend a large amount of human and material resources, and the replacing difficulty of bearing is large simultaneously, and cost is high, and larger to the normal Influence to operation of bridge.
Summary of the invention
The purpose of this utility model is to provide a kind of bridge pad capsule formula protector, to solve following technical problem, not only can reduce the raw-material performance requirement of bearing, thereby reduce bearing buying expenses, can reduce the workload of bearing inspection, maintenance simultaneously, avoid the bearing replacement causing because of durable problem, reduced bridge later stage operation cost and maintenance difficulty, and avoided the impact of bearing replacement on present situation traffic.
In order to realize foregoing invention object, the technical scheme that the utility model adopts is as follows:
Bridge pad capsule formula protector, comprises utricule, filler, filling device and upper and lower linkage; Described utricule is connected with superstructure, the substructure of bridge by upper and lower linkage, and bridge pad and pinner are enclosed in wherein; On utricule, be provided with according to the difference of filler and adopt different valve structures, play the filling device that filler adds and discharges.
Described utricule adopts rubber, plastics, resin or metal material to make.
In described utricule, filler is set, filler adopts inert gas or liquid according to type of support and material characteristics thereof.
Described upper and lower linkage is to adopt the multi-form syndetons such as bonding, welding or bolt connection.
The utlity model has following advantage: the employing of this capsule formula protector, bearing can be placed in to closed environment, make it not be subject to the impact of hazardous substances in extraneous dust, ultraviolet ray, atmosphere, the erosion of marine environment chlorine particle, water impact and object strikes, inert gas or liquid can be filled in capsule formula device inside simultaneously, effectively delay the natural aging process of the material of bearing own, thereby effectively increase the durability of bearing, reduce bearing cost.This device durability itself is high, and strong to the applicability of distortion, it is convenient to check, keep in repair, change, can effectively reduce the later stage check, maintenance work amount, avoided the replacing to bearing during road operation simultaneously.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
In figure, number: the 1st, superstructure, the 2nd, upper linkage, the 3rd, utricule, the 4th, lower connecting device, the 5th, substructure, the 6th, filler, the 7th, filling device, the 8th, bridge pad and pinner.
Detailed description of the invention
Bridge pad capsule formula protector described in the utility model, comprises utricule 3, filler 6, filling device 7 and upper and lower linkage 2,4, and its structure is referring to Fig. 1.Described utricule 3 is connected with superstructure 1, the substructure 5 of bridge by upper and lower linkage 2,4, and bridge pad and pinner 8 are enclosed in wherein; On utricule 3, be provided with according to the difference of filler and adopt different valve structures, play the filling device 7 that filler adds and discharges.The interior filler 6 that arranges of described utricule 3, filler 6 adopts inert gas or liquid according to type of support and material characteristics thereof.Described upper and lower linkage the 2, the 4th, adopts the multi-form syndetons such as bonding, welding or bolt connection.
Being described below of concrete all parts:
Utricule is the main-body structure of this device, and it should have:
1, airtight performance is good, can guarantee that bearing environment and the external world isolate completely, increases the bearing effect in application life thereby reach;
2, good toughness, can adapt to the Deformation Demands of bridge superstructure, avoids drawing superstructure and is out of shape the destruction that causes protector;
3, there is certain intensity, according to the difference of environment for use, can prevent water impact and object strikes time, occur destroying;
4, have good durability, envelop materials should be not less than 10 years application life;
Utricule can adopt the materials such as satisfactory rubber, plastics, resin, metal to make.
For increasing the effect of bridge pad capsule formula protector, can be chosen in filler is set in utricule.Filler can, according to type of support and inert gas or liquid for material characteristics timber, increase the bearing effect in application life to reach.
Filling device is to realize the device that filler adds and discharges, and can adopt different valve structures according to the difference of filler.
Upper and lower linkage is to realize the device that utricule and bridge superstructure and basis, bottom are reliably connected, can be bonding according to the material of utricule, superstructure, substructure and construction features employing, welding, bolt connection etc. are multi-form.
An embodiment of the present utility model:
Certain bridge location is in coastal area, in marine environment, for avoiding the impact of chlorion on bearing durability in air, adopt bridge pad capsule formula protector of the present utility model, can ensure bearing durability, reduce construction costs, reduce bearing maintenance, maintenance load.
In engineering construction, after treating bridge main body construction, measure each bearing place concrete condition, and adopt rubber to make protective cover utricule according to measurement result, and on utricule, establish charging valve, utricule adopts bonded adhesives to be adhered in superstructure and substructure, after utricule installs, utilize charging valve in utricule, to fill nitrogen, complete the installation of complete unit.Because bearing is positioned over nitrogen environment, completely cut off with extraneous marine environment, effectively increase the application life of bearing.When bridge inspection, only need periodic measurement utricule internal gas pressure, if air pressure do not occur extremely, can judge that bearing is in normal operating condition.
