Abstract
The utility model relates to a steel box girder rapid butt joint leveling device which comprises a counter-force girder, wherein a first supporting rod and a second supporting rod which are perpendicular to the counter-force girder are respectively welded at one end and the middle of the counter-force girder, the lower end of the second supporting rod is welded with a connecting plate, the connecting plate is connected with a clamp through a bolt, the clamp comprises a clamping plate, the length of the clamping plate is greater than the width of a flange plate of I-shaped steel at the end part of the steel box girder, the bottoms of the two ends of the clamping plate are respectively and fixedly provided with an L-shaped hook, the two hooks are oppositely arranged, and the distance between the opposite ends of the two hooks is smaller than the width of the flange plate of the I-shaped steel at the end part of the steel box girder. The supporting rod is supported on the beam section to be installed, the jack is adopted to upwards push the counter-force beam on the installed beam section, the end parts of the two beam sections can be quickly leveled, and the construction efficiency is improved.
Description
Technical Field
The utility model belongs to the technical field of steel structure bridge construction, and relates to a device for quickly leveling the butt joint end of two beam sections when the two beam sections are butted in the installation process of a steel box beam.
Background
Steel box girders of steel structure bridges are generally processed in sections and butted on the bridges. And I-beams with certain lengths extend from the end parts of the two butt-jointed beam sections respectively, during butt joint, the crane lifts one beam section to be installed, levels and aligns with the end part of the other installed beam section, and then fixes the I-beams at the end parts of the two beam sections through the clamping plates by using bolts. In the process, the height of the beam section to be installed in the air is not easy to control, manual repeated adjustment is needed, the time consumption is long, and the construction efficiency is low.
Disclosure of Invention
Aiming at the problems, the utility model provides the quick butt joint leveling device for the steel box girder, which can quickly level the butt joint ends of two girder sections and improve the butt joint construction efficiency of the girder sections.
The technical scheme of the utility model is as follows:
the utility model provides a steel case roof beam docks levelling device fast which characterized in that: the steel box beam end I-steel flange plate comprises a counter-force beam, wherein a first supporting rod and a second supporting rod which are perpendicular to the counter-force beam are welded at one end and the middle of the counter-force beam respectively, a connecting plate is welded at the lower end of the second supporting rod, the connecting plate is connected with a fixture through bolts, the fixture comprises a clamping plate, the length of the clamping plate is larger than the width of a flange plate of the steel box beam end I-steel, a screw hole which is connected with the connecting plate through bolts is preset in the clamping plate, an L-shaped hook is fixedly arranged at the bottom of each of two ends of the clamping plate respectively, the two hooks are arranged oppositely, and the distance between the opposite ends of the two hooks is smaller than the width of the flange plate of the steel box beam end I-steel.
The utility model adopts the steel materials commonly used in the construction site for processing, has simple structure, small volume and convenient use, is matched with the jack for use, can quickly level the end parts of the two beam sections, and improves the construction efficiency of the butt joint of the two ends.
