the elevation block is arranged on the bottom surface of the plumb;

The concave sliding block is connected to the I-steel upright post in a sliding way, and is provided with a first bolt in threaded connection with the concave sliding block so as to be abutted against the I-steel upright post;

the concave elevation plate is connected to the concave sliding block through a pin shaft, and is connected with a second bolt through threads on the convex part of the concave elevation plate, and the second bolt passes through the convex part to be abutted against the concave sliding block;

the elevation groove is arranged on the concave elevation plate and can enable the elevation block to extend into the elevation groove.

By adopting the structure, the measuring direction is determined by the plumb, then the elevation position can be measured by the measuring tool by the tape measure, and the bottom surface of the elevation block is used as the mark of the elevation position; and moving the concave elevation plate to the position of the elevation block, enabling the elevation block to enter the elevation groove, then rotating the elevation plate, enabling the bottom surface of the elevation plate to be parallel to the bottom surface of the elevation block and located on the same plane, and abutting against the concave sliding block by using a second bolt, so that the elevation surface is determined, and the obtained elevation surface is higher in precision.

As a further improvement of the cast-in-situ pavement concrete elevation control device, the I-steel beam is also inserted with wind shields which are arranged on two sides of the plumb line.

With this structure, the wind deflector can prevent the plumb from being affected by wind.

As a further improvement of the cast-in-situ pavement concrete elevation control device, the elevation block is square, and the elevation groove is rectangular.

By adopting the structure, the elevation block can be conveniently inserted.

The utility model can find a horizontal plane at the elevation position through the plumb as the elevation surface, and then marks the elevation surface through the specific elevation plate so as to control the elevation of the cast-in-situ concrete pavement.
