Abstract
The utility model discloses bridge beam supports technical field specifically says to disclose a girder steel special use is increaseed and is turned down support. The structure that constitutes this support include its structure including the bottom suspension bedplate that is provided with the pelvis, by upper bracket board, spherical crown board, middle steel lining board form subtract isolation structure set up in in the pelvis of bottom suspension bedplate, be provided with on the bottom suspension bedplate with at least one access of pelvis intercommunication, be provided with the rubber bed course in the bottom surface of middle steel lining board, bottom suspension bedplate pelvis with be provided with low -melting solid matter in the space of the laminiform one -tenth of rubber pad. This girder steel special use is increaseed and is turned down support can realize the bridge because geological conditions or other atress effect and the corner that causes changes and the function of height control.
Description
Technical field
This utility model belongs to technical field of bridge, i.e. relates to a kind of special heightening of girder steel that can adjust its height and turns down bearing.
Background technology
Highway steel bridge is evolving, but its supporting bearing does not has proprietary design, still uses normal concrete bearing.Either its performance or size design all calculate according to concrete-bridge and check, and are not appropriate for present highway steel bridge the most in some aspects.
Owing to girder steel design cannot carry out stretch-draw to top concrete, existing consideration utilizes girder steel itself to realize, it is necessary to special carrier coordinates.By the adjustment of height of support is made girder steel stress, it is ensured that while the pressure effect of top concrete, additionally it is possible to realize the corner change that bridge causes due to geological conditions or other stress effect.The structure of the making used at present is then difficult to both and takes into account, and therefore cannot meet the stress needs of girder steel.
Summary of the invention
The purpose of this utility model be just to provide a kind of by adjust its highly realize adjust bearing bearing capacity and meet its corner change special the heightening of girder steel turn down bearing.
Realizing this utility model above-mentioned purpose, the technical scheme used is:
A kind of special heightening of girder steel turns down bearing, and its structure includes the lower support plate being provided with pelvic cavity, is made up of in the pelvic cavity that seismic isolation and reduction structure is arranged at described lower support plate upper bracket plate, spherical crown plate, middle steel liner plate；Described lower support plate is provided with at least one adjusting hole connected with described pelvic cavity, the bottom surface of described middle steel liner plate is provided with rubber spacer, the space that described lower support plate pelvic cavity and described rubber spacer are formed is provided with the solid matter of low melting point.
Constitute special the heightening of above-mentioned girder steel to turn down the additional technical feature of bearing and also include:
The bottom surface of pelvic cavity corresponding to the adjusting hole of described middle steel liner plate is provided with annular groove；
It is provided with heater block in described annular groove；
The described middle steel liner plate sidewall with described pelvic cavity is provided with sealing ring.
A kind of special heightening of girder steel provided by the utility model turns down bearing compared with prior art, have the following advantages, owing to the bottom surface of steel liner plate middle in constituting this bearing pelvic cavity is provided with rubber spacer, and in the space that rubber spacer is formed, it is provided with the solid matter of low melting point, therefore, it is possible to realize corner change and the function of height adjustment that bridge causes due to geological conditions or other stress effect, in order to the bearing being respectively provided with on balanced adjustment pier forms uniform load distribution to beam body.
Accompanying drawing explanation
Special the heightening of girder steel that Fig. 1 provides for this utility model turns down seat structure schematic diagram.
Detailed description of the invention
Below in conjunction with the accompanying drawings special the heightening of girder steel provided by the utility model is turned down the structure of bearing and use principle is described in further detail:
The special of this utility model offer is provided and heightens the cross section structure schematic diagram turning down bearing.The structure constituting this bearing includes being provided with the lower support plate 2 of pelvic cavity 1, formed seismic isolation and reduction structure be arranged in the pelvic cavity of lower support plate by upper bracket plate 3, spherical crown plate 4, middle steel liner plate 5, above-mentioned lower support plate is provided with connect with pelvic cavity be provided with this plug wire of plug wire 6(and can set as required) adjusting hole 7；The middle steel liner plate sidewall with pelvic cavity is provided with sealing ring 8, makes pelvic cavity be internally formed confined space；In constituting said structure, the bottom surface of middle steel liner plate is provided with rubber spacer 11, arranges the solid matter 10 just like paraffin or other low melting points in the space that lower support plate pelvic cavity and rubber spacer are formed.
Heating during use, to lower support plate so that the solid matter 10 of low melting point in pelvic cavity, and released by adjusting hole, or the solid matter 10 of low melting point it is added thereto to by this adjusting hole, regulate the height of bearing, in order to adjust bridge and the stress of bridge pier；Ensure that vibration absorption and isolation support can effectively play a role.Can avoid construction error or the pier height of support that causes of sedimentation not, bias, the problem such as come to nothing.Can be used for monitoring Bearing Seat Force situation, the most convenient to use, save a large amount of manpower, financial resources, it is ensured that the use safety of bridge.Simultaneously because be provided with rubber spacer 11 in the bottom surface of middle steel liner plate, it is possible not only to directly carry the vertical loads of bridge, and due to the elastic characteristic being had of this rubber spacer, it is also possible to correct the corner deformation that bridge or bridge pier occur because of stress.
Constituting, above-mentioned girder steel is special to be heightened in the structure turning down bearing,
The bottom surface of pelvic cavity corresponding to the adjusting hole of middle steel liner plate 5 is provided with annular groove 9, can be prevented effectively from when inside pelvic cavity, the solid matter 10 of injecting low melting point is heightened in filling, cause heightening auxiliary agent centre steel liner plate 5 is pushed up partially because of adjusting hole 7 heart position the most wherein, cause the generation of its displacement problem；
It is provided with heater block 12, in order to the heating and melting to the solid matter 10 of low melting point in above-mentioned annular groove 9.
