Description
Technical Field
The utility model relates to the technical field of steel box girder bridge construction, in particular to a matching piece for alignment between girder sections.
Background
With the concept of rapid economic development and sustainable development in recent years, the construction of the steel box girder bridge is more emphasized by the nation. The steel box girder is divided into a plurality of sections along the longitudinal direction of the bridge, the sections are manufactured in a factory, the length of each section is determined by the factory according to road transportation conditions, hoisting capacity, construction site arrangement and other conditions, and the sections are divided into transverse beam blocks, main beam blocks and beam supporting blocks, wherein the maximum size is 3500 multiplied by 13500 multiplied by 1500mm, and the maximum tonnage is 35 t. The steel box girder assembly generally takes a pier top girder base plate cross line pre-defined in a manufacturing factory as a reference, matches corresponding reference blocks on a pier, adjusts and fixes the reference blocks after placement and takes the reference blocks as a positioning reference for hoisting, and is assisted with a stacking plate for fixed connection after hoisting and assembling. The inevitable position deviation or deformation of the beam sections can be generated in the construction process due to hoisting deformation, welding deformation or size deviation, and the assembly of the beam ends of the steel box beam is difficult.
Disclosure of Invention
Aiming at the problem that the assembly of the beam sections is difficult, the utility model provides a beam section alignment matching piece.
The matching pieces for aligning between the beam sections are respectively arranged above the connecting seams of the two steel box beams and comprise
The angle steel block, the locating pin, the bolt and the code plate, wherein the horizontal part of the angle steel block is welded on the steel box girder, the center of the vertical part of the angle steel block is provided with a pin hole, the two horizontal sides beside the pin hole are provided with screw holes, and the two angle steel blocks are fixed through the locating pin and the bolt; and a plurality of stacking plates are welded above the joint seam of the steel box girder.
The matching piece is manufactured and welded before the integral beam section is cut off in a split mode. During operation, a crane is commanded by a crane to move to hoist the steel box girder, the two connecting pieces are fixed by the positioning pins when the steel box girder is in place, the steel box girder is taken as a primary positioning reference, the bolts are screwed down to prevent the girder section from being misplaced, and finally, the stacking plates are welded to prevent the girder section from being displaced when the lower girder section is hoisted.
In order to avoid deformation of the matching piece, the angle steel block is arranged above a web plate of the steel box girder.
And a ceramic liner is arranged below the steel box girder connecting seam and is used for welding the outer surface of the steel box girder after the steel box girder is in place, so that the welding quality is ensured.
Optimally, for convenient adjustment and guarantee of installation accuracy of the steel box girder, the pin holes are horizontally arranged waist holes, and the number of the screw holes is at least four. And after the two connecting pieces are pinned by the positioning pin, measuring and positioning by using a total station, wherein the horizontal adjusting beam section is positioned on a correct axis. The steel box girder uses hydraulic jack and chain block cooperation adjustment removal, because there is girder segment weight about 120 tons, it is very difficult to move the adjustment of frictional force greatly, can set up the antifriction plate temporarily in the sand box top in order to reduce the convenient adjustment of frictional force.
The alignment matching piece between the beam sections is simple and practical in structure, the steel box beams are firmly assembled, the positioning between the beam sections is accurate, and the alignment matching piece is worthy of popularization.
