Description
Technical Field
The utility model relates to a precast beam construction technical field, concretely relates to a transfer slope ware for adjusting precast beam base support pre-buried steel sheet longitudinal and transverse slope.
Background
Highway bridges are usually provided with longitudinal and transverse slopes according to geographical conditions, wherein the gradient of the longitudinal slope is generally 1% -5%, and the gradient of the transverse slope is generally 1% -4%. In order to ensure the vertical axis stress of the bridge bearing and prevent bias voltage, the prior art has two modes for slope adjustment: one method is that when the precast beam is precast, sand is poured at a branch point on a pedestal to adjust the height of a pre-buried steel plate at the bottom of the precast beam; and the other method is that the steel plate gap plugging treatment is carried out after the beam is erected without adjusting the position of the bottom steel plate of the precast beam. Both methods can only adjust the longitudinal slope of the precast beam, and the transverse slope is controlled by the beam forming template and the beam erecting time, but the control difficulty is higher. When the bridge erected according to the method is maintained, the phenomenon that the beam bottom support has distortion is sometimes found, because the longitudinal and transverse slopes of the embedded steel plates at the beam bottom are inaccurate, and the support is biased due to the fact that the load of a vehicle exerts pressure after the bridge is operated, so that the bridge is distorted. Such phenomena seriously affect the service life of the bridge, seriously threaten the safety of vehicles and people, and have high repair difficulty and high cost.
Disclosure of Invention
The utility model aims to provide a difficult problem that exists is adjusted to present bridge length and breadth slope, provide one kind and had both adjustable longitudinal gradient, also can control the cross slope on the system roof beam pedestal, need not to adjust system roof beam template, also need not to adjust the cross slope during the frame roof beam, the universal slope regulator that can put in place the regulation in one step.
The technical scheme of the utility model as follows:
the utility model provides a pre-buried steel sheet ball pivot formula universal slope ware of precast beam which characterized in that: the adjustable base plate comprises a rectangular base plate and a top plate, wherein a spherical hinge bearing is fixedly arranged in the middle of the top surface of the base plate, a connecting screw rod is arranged at the top of the spherical hinge bearing, adjusting nuts are respectively welded on the top surface of the base plate close to 4 corners, each adjusting nut is in threaded connection with the lower end of an adjusting bolt, and the top of each adjusting bolt is an upward protruding cambered surface; and a connecting nut is welded in the middle of the bottom surface of the top plate and is in threaded connection with the upper end of a connecting screw rod of the spherical hinge bearing, arc-shaped grooves are respectively formed in the bottom surface of the top plate close to 4 corners, and the top of each adjusting bolt is supported in one arc-shaped groove.
The utility model has simple structure and convenient installation, adopts spherical hinge connection in the middle and can rotate in multiple directions; the cross slope and the longitudinal slope can be directly adjusted on the beam-making pedestal, the adjustment of the cross slope and the longitudinal slope is accurate, the adjustment of the cross slope is not needed when the beam is erected, and the construction difficulty when the beam is erected is reduced; by using the slope regulator, the beam-making template is not divided into high and low sides, the turning around of the template is not needed, the time and the labor are saved in the beam-making process, the working efficiency is improved, and the cost can be saved.
