Along with the continuous increase of domestic Foundation Design building project, the proportion sustainable growth in Foundation Design is built of different types of rridges and aqueduct structure.The beam body takes place can change the stress of upper and lower part structure under the situation of differential settlement on its basis, brings hidden danger for the safety of structure.And, because the uneven technical barrier of bridge pad pressure-bearing that construction error, various precast beam and beam structure that girder construction support pinner absolute altitude is difficult to avoid allow the existence of factors such as height error to make different types of rridges, aqueduct structure exist in work progress after the micro-deformation that produces after the stretch-draw, bridge pad completion of processing to be difficult to avoid.One of method that solves differential settlement in the existing bridge engineering is exactly to adopt the filled polyurethane height-adjustable supports to realize.
The end that a part of polyurethane height-adjustable supports injecting pipeline leads to end basin in the existing polyurethane height-adjustable supports does not design the sealing steel plate washer, and this causes the local squeeze and destroy of rubber bearing plate easily; Though part polyurethane height-adjustable supports injecting pipeline leads to the end design of the end basin sealing steel plate washer is arranged, but will not seal the steel plate washer mounting table and carry out necessary fixedly processing with the sealing steel plate washer, the rubber bearing plate can form certain adhesive strength by the sealing steel plate washer under action of long-term load, the rubber bearing plate is by jack-up when previous stage is heightened perfusion, the sealing steel plate washer easily with the rubber bearing plate by jack-up, make the polyurethane elastomer of perfusion enter the back one-level and heighten and solidify in the injecting pipeline and sealing back one-level is heightened the injecting pipeline, and then influence back one-level is heightened the realization of function.
The utility model content
The technical problem that the utility model solves be exactly easy to use, be coated with the lining operation and simply can repeatedly heighten pot rubber bearing.
For solving the problems of the technologies described above, the technical scheme that the utility model can repeatedly be heightened the pot rubber bearing employing is: comprise upper base plate, rubber bearing plate, end basin, on basin of the described end, offer the injecting pipeline, described injecting pipeline is two or more, in each described injecting pipeline, be provided with one way valve, be provided with sealing steel plate washer mounting table at described injecting pipe end mouth place, on described sealing steel plate washer mounting table, be bonded with the sealing steel plate washer by the pressure sensitive bonding adhesive.
Provided by the utility modelly can repeatedly heighten pot rubber bearing and compared with prior art have the following advantages: owing to comprise upper base plate, the rubber bearing plate, end basin, on basin of the described end, offer the injecting pipeline, described injecting pipeline is two or more, in each described injecting pipeline, be provided with one way valve, be provided with sealing steel plate washer mounting table at described injecting pipe end mouth place, on described sealing steel plate washer mounting table, be bonded with the sealing steel plate washer by the pressure sensitive bonding adhesive, when previous stage is injected the polyurethane packing material by first auxiliary agent pipeline bottom the rubber bearing plate, guaranteed that back one-level heightens injecting pipeline effective seal, thereby the polyurethane packing material of avoiding previous stage to heighten perfusion enters the back one-level and heightens in the injecting pipeline and to solidify and sealing back one-level is heightened the injecting pipeline, and then influence back one-level is heightened the realization of function; The injecting pipeline is twice or more than the twice, can realize repeatedly heightening.
Description of drawings
Fig. 1 can repeatedly heighten the structural representation of pot rubber bearing for the utility model;
Fig. 2 is an A place partial enlarged drawing among Fig. 1.
The specific embodiment
Structure and the use principle that can repeatedly heighten pot rubber bearing to the utility model below in conjunction with accompanying drawing are described in further details.
As depicted in figs. 1 and 2, the utility model can repeatedly be heightened the structural representation of pot rubber bearing, this can repeatedly be heightened pot rubber bearing and comprise upper base plate 1, rubber bearing plate 2, end basin 3, on end basin 3, offer the first injecting pipeline 4 and the second injecting pipeline 7, certainly as required, the injecting pipeline can be for more than two, in the first injecting pipeline 4, be provided with one way valve 41, in the second injecting pipeline 7, be provided with one way valve 71, be provided with the first sealing steel plate washer mounting table 42 at the end port place of the first injecting pipeline 4, on the first sealing steel plate washer mounting table 42, be bonded with the first sealing steel plate washer 43 by the pressure sensitive bonding adhesive, be provided with the second sealing steel plate washer mounting table 72 at the end port place of the second injecting pipeline 7, on the second sealing steel plate washer mounting table 72, be bonded with the second sealing steel plate washer 73 by the pressure sensitive bonding adhesive.
Before heightening for the first time, rubber bearing plate 2 can form certain adhesive strength with the first sealing steel plate washer 43 and the second sealing steel plate washer 73 under action of long-term load.When heightening for the first time, polyurethane packing material 5 injects injecting pipeline 4 by one way valve 41.During with the bonding force that seals between the steel plate washer mounting table 42, polyurethane packing material 5 seals steel plate washer 43 with first and backs down the pressure that polyurethane packing material 5 in injecting injecting pipeline 4 forms greater than the first sealing steel plate washer 43.Along with the continuous injection of polyurethane packing material 5, polyurethane packing material 5 will be rubber bearing plate 2 jack-up to the design amount of heightening.Because the adhesive strength that the adhesive strength between the second sealing steel plate washer 73 and the second sealing steel plate washer mounting table 72 forms with the second sealing steel plate washer 73 under action of long-term load much larger than rubber bearing plate 2, rubber bearing plate 2 can separate with the second sealing steel plate washer 73, and the strong bond between the 73 meeting maintenances of the second sealing steel plate washer and the second sealing steel plate washer mounting table 72.
Carrying out secondary when heightening, polyurethane packing material 5 injects injecting pipelines 7 by one way valve 71.During bonding force that the pressure that the polyurethane packing material 5 in injecting injecting pipeline 7 forms seals between the steel plate washer mounting table 72 greater than the second sealing steel plate washer 73 and second, polyurethane packing material 5 will seal steel plate washer 73 to second and back down.Along with the continuous injection of polyurethane packing material 5, polyurethane packing material 5 will be the polyurethane rubber plate jack-up of heightening formation for the first time to the design amount of heightening.
