Description

Technical Field

[0001] The utility model belongs to the technical field of bridge construction, and more specifically, particularly relates to a beam bottom slope adjusting device. Background Art

[0002] In bridge construction, steel plates are usually embedded at the bottom of the beam before the supporting beam is extended into the bottom of the beam. When the bottom of the supporting beam is connected to the steel plate, a slope adjusting device is required to adjust the slope of the supporting beam. When the slope adjusting device is used, the slope of the top plate is first adjusted before the bottom of the supporting beam is placed on the top plate.

[0003] According to CN202222735141.0, an embodiment of the utility model provides a prefabricated beam slope adjuster, which relates to the technical field of slope adjusters. The prefabricated beam slope adjuster includes a first plate body, a second plate body and two adjusting parts, the first plate body is convexly provided with a first hinge part, the second plate body is convexly provided with a second hinge part, the first hinge part and the second hinge part are hinged, and the first plate body and the second plate body are arranged at intervals, and the two adjusting parts are respectively located on both sides of the hinge position, each adjusting part includes a base and a threaded lifting column, the base and the threaded lifting column are threadedly matched, the base is fixedly connected to the second plate body, one end of one threaded lifting column away from the base is used to abut against the middle of one end of the first plate body, and the other end of the threaded lifting column away from the base is used to abut against the middle of the other end of the first plate body. The prefabricated beam slope adjuster can reduce the lateral leveling process when performing longitudinal slope adjustment operations, improve the longitudinal slope adjustment efficiency of the prefabricated beam slope adjuster, and reduce the work intensity of the operator.

[0004] Based on the above, the existing slope adjustment device generally adjusts the slope of the top plate through four sets of threaded rod structures. When the staff adjusts the slope of the top plate, the staff needs to adjust the four sets of threaded rods one by one, and it is necessary to ensure that the adjustment ratios of the four sets of threaded rods are the same. At the same time, particles such as debris are easily attached to the top plate, and the surface of the top plate needs to be wiped, which is more cumbersome. Utility Model Content
