The characteristic of the bearing leveling structure of the utility model is: each is provided with the vertical two ends of said precast beam body by leveling projection protruding under the beam; Leveling projection and precast beam body one are pre-formed; Its bottom surface that contacts with bridge pad is provided with and the opposite gradient of precast beam body design grade, i.e. vertically ratio of slope-il% and/or laterally ratio of slope-it%.
Another technical problem that the utility model need solve provides a kind of body formed mould of precast beam of producing above-mentioned bearing leveling structure.It is following that the utility model solves this technical problem the technical scheme that is adopted:
The body formed mould of the precast beam of the utility model; Comprise loose tool; It is characterized in that: the vertical two ends of said loose tool are provided with two leveling projection shaping grooves by its surface sinking; These two leveling projection shaping grooves are inherent corresponding with the bridge pad position respectively to be provided with leveling projection soffit formwork, and is provided for regulating the adjusting device of leveling projection soffit formwork gradient.
In technique scheme; In two leveling projection shaping grooves; The longitudinal length of one of them leveling projection shaping groove is greater than the longitudinal length of leveling projection soffit formwork, is provided with dismountable position between one of which or two longitudinal terminal surfaces and the leveling projection soffit formwork longitudinal terminal surface and adjusts piece.
The beneficial effect of the utility model is that bearing leveling structure is easy to construction, can guarantee bearing leveling construction precision, can eliminate diseases such as bearing destroys in advance effectively; Precast beam body and leveling projection are one-body molded, and can adapt to the pre-formed of different length beam body and diverse location leveling projection well, and production compliance is strong.
