Abstract
The utility model relates to a steel box girder butt-joint leveling device which comprises a supporting beam, a counter-force beam and a jack, wherein the rear end of the supporting beam is connected with one end of the counter-force beam through a bolt; a U-shaped clamp is welded at the front end of the supporting beam, the U-shaped clamp comprises a connecting plate, the connecting plate is welded with the front end of the supporting beam, two parallel clamping plates are welded at two sides of the connecting plate, and two fastening bolts penetrate through one clamping plate; a supporting plate vertical to the longitudinal axis of the supporting beam is welded on the supporting beam, an arc-shaped clamping groove is formed in the top edge of the supporting plate, the cylinder body of the jack is supported in the arc-shaped clamping groove in the supporting plate, and the base is supported on the counter-force beam. The utility model clamps the stiffening rib on the inner side of the installed steel box girder through the clamp, and the jack pushes the stiffening rib on the inner side of the steel box girder to be installed to level, so that the panel of the steel box girder is not damaged, and the installation and disassembly speed is high.
Description
Technical Field
The utility model belongs to the technical field of bridge construction, and relates to an aligning and leveling device between sections when steel box girders or steel structure cable towers of a steel structure bridge are installed in sections.
Background
When the steel box girder is installed in sections, the end surfaces of two sections need to be aligned and then welded, and generally, when one section is installed, the crane lifts the other section to be in butt joint with the installed section. Because the crane can not accurately control the height of the beam section to be installed, an L-shaped reaction frame is generally welded on a panel of the installed steel beam section in construction, one end of the L-shaped reaction frame extends to the upper part of the beam section to be installed, a jack is arranged between the panel of the section to be installed and the L-shaped reaction frame, when the crane lifts the beam section to be installed to be slightly higher than the installed beam section, the beam section to be installed is pushed downwards by the jack, and the two beam sections are leveled through the matching of the crane and the jack. The method is easy to cause the deformation of the steel box girder panel, and secondary damage can be caused to the steel girder panel when the reaction frame is cut off after the butt joint is finished.
Disclosure of Invention
The utility model aims to solve the problems and provides a steel box girder butt joint leveling device which avoids damage to a steel box girder base metal.
The technical scheme of the utility model is as follows:
the utility model provides a steel case roof beam butt joint levelling device which characterized in that: the device comprises a supporting beam, a counter-force beam perpendicular to the supporting beam and a jack, wherein the rear end of the supporting beam is fixedly connected with one end of the counter-force beam through a bolt; a U-shaped clamp is welded at the front end of the supporting beam, the U-shaped clamp comprises a connecting plate, the connecting plate is perpendicular to the longitudinal axis of the supporting beam and is welded with the front end of the supporting beam, two clamping plates which are parallel to each other are welded on two sides of the connecting plate, and two fastening bolts penetrate through one clamping plate; the supporting beam is welded with a supporting plate vertical to the longitudinal axis of the supporting beam, the top edge of the supporting plate is provided with an arc-shaped clamping groove, the cylinder body of the jack is supported in the arc-shaped clamping groove in the supporting plate, and the base of the jack is supported on the counter-force beam.
The utility model clamps the stiffening rib on the inner side of the installed steel box girder through the clamp, and simultaneously the jack pushes the stiffening rib on the inner side of the steel box girder to be installed to level, so that the panel of the steel box girder is not damaged; the leveling device is not welded with the steel box girder, the mounting and dismounting speed is high, and the device can be used in a turnover way. The utility model can also be used for butt joint leveling when the steel structure cable tower is installed in sections.
