Description

Technical Field

[0001] The utility model belongs to the technical field of prefabricated beams, and particularly relates to an adjusting device for adjusting the outer dimensions of a wedge-shaped block with high precision. Background Art

[0002] Wedges play a vital role in bridge engineering, mainly including leveling, protecting bearings, buffering and transferring loads, improving bridge performance and protecting bridge safety. Therefore, the accuracy of the wedge's dimensions directly affects the performance and safety of the bridge.

[0003] At present, wedge blocks are prefabricated at both ends of the bottom of the beam. The wedge blocks are generally adjusted by sand padding or fine-rolled threaded steel screws. Sand padding will cause compaction settlement, while fine-rolled threaded steel screws will cause ordinary screw nuts to loosen during the pouring of the wedge blocks due to vibrating concrete, which will affect the external dimensions of the wedge blocks and make it impossible to guarantee the performance of the bridge. In addition, the position adjustment of the wedge blocks requires the overall adjustment of the bottom mold, which has many difficulties and affects the prefabrication efficiency.
