[0001] The present application relates to the technical field of road construction, and in particular to an airport concrete pavement template elevation adjustment device. Background Art

[0002] During the process of supporting steel formwork, since the steel formwork is relatively heavy, it is generally adjusted by manpower or some manual adjustment devices are made to adjust it. Usually some simple tools or mechanical devices, such as crowbars, adjustment brackets, etc., are used to adjust the position and elevation of the formwork by manpower.

[0003] When a manual adjustment device is used, the manufacture of the manual adjustment device is relatively complicated, and the mechanical device is relatively laborious or troublesome to manufacture.

[0004] When using crowbars, adjustment brackets, etc. to adjust the position and elevation of the template by manpower, the adjustment accuracy is low and the traditional manual adjustment method is difficult to achieve the required accuracy, which can easily cause unevenness on the road surface and affect the road quality. At the same time, the adjustment efficiency is low: the adjustment speed is slow, the labor intensity is high, and it cannot meet the requirements of modern construction. Utility Model Content

A crowbar 5 is provided at the upper end of the rotating shaft 4. In this embodiment, the outer wall of the crowbar 5 is welded to the arc-shaped side wall of the rotating shaft 4. In this embodiment, the crowbar 5 is set as a hexagonal steel. The length direction of the crowbar 5 is perpendicular to the axis direction of the rotating shaft 4, and the tip of the crowbar 5 abuts against the concrete pavement template body 9. A limit assembly 6 for limiting the position of the rotating shaft 4 is provided on the upper base 2.

[0036] The limiting assembly 6 includes two coaxially arranged limiting tubes 61, which are coaxially arranged with the rotating shaft 4.
