Description

Technical Field

[0001] The invention relates to the technical field of box beam hangers, in particular to a positioning and hanging device for installing a box beam. Background Art

[0002] The box girder is hollow inside with flanges on both sides of the upper part. The box girder is a common structural form for large-span bridges and is generally used on bridges with larger spans. During construction, the box girder is usually placed on the pier by hoisting after the pier construction is completed. In the actual construction process, small box girders are widely used. Usually, more than two box girders are placed side by side on the jacks on the piers, and then the rubber bearings supporting the box girder on the piers are installed for support installation. During hoisting, two cranes are usually used to hang the two ends of the box girder respectively, and lift and lower at the same time. After each box girder is docked to the pier, the steel bars set on the side of the box girder are tied together and concrete is poured to make each box girder integrally formed. The current positioning and hanging device for box girder installation is not convenient for self-leveling installation guided by the piers, and usually relies on the adjustment of two cranes. The box girder is very susceptible to collision due to wind force during installation. At the same time, it is also not convenient to realize the steel bar hanging calibration. The steel bars between adjacent box girders are very easy to be misplaced, which requires a long time to adjust, which is time-consuming and labor-intensive, and it is also easy to affect the subsequent pouring and molding effect.

By utilizing the characteristics of the vertical support of the bridge piers, the bridge pier positioning device 6 can only lift and slide vertically, so as to realize the automatic leveling work of the box beam body 103 on the top of the traction support channel steel 101. The center of gravity leveling structure adopted in this structure is less affected by factors such as wind force, and no manual pulling and leveling work is required, which is more stable and safe, avoiding the traditional center of gravity maintenance method of using counterweight or adding mechanical structure, which uses a crane for hoisting, and still cannot avoid the skew effect caused by wind force and normal shaking on the box beam body 103, and it is still easy to collide, while this structure can To achieve bidirectional traction, the lifting and hoisting of the crane is coordinated with the pulling down of the pier positioning device 6, which is stable, reliable and easy to install. By placing the pier positioning device 6 between the piers, the workers manually rotate the opposing screw rods 605 with reverse threads to drive the two expansion installation columns 603 to move in opposite directions, and drive the expansion positioning rollers 6041 to stick to the cylindrical pier for limiting.

At the same time, the box girder casting steel bars 104 on the box girder body 103 are 4 is more convenient for workers to tie the steel bars and then cast, and it also further improves the accuracy and stability of the box beam body 103 when it is lowered. Finally, the support channel steel 101 can be disassembled. When the lifting control shaft 301 does not interfere with the extrusion pier, under the extrusion of the reset spring 303, the rack 302 is engaged to drive the control gear 402 to control the rotating mounting frame 501 to maintain the vertical initial position, which does not affect the connection between the support channel steel 101 and the hanging mounting frame 201 to install the box beam body 103. When installing the hanging mounting frame 201, the steel bar positioning groove 503 is aligned with the box beam casting steel bar 104 on the box beam body 103 to be installed.
