The output end of the first hydraulic push cylinder 11 is fixedly connected to an extended formwork 12. When in use, the device is moved to the bottom of the large-slope concrete structure roof by using the provided moving wheels 2. By driving the first motor 9, the lifting column 6 and the support formwork 10 are lifted and moved under the screw rotation of the screw rod 8 and the lifting column 6, so as to be adjusted and supported according to the position of the roof formwork, thereby improving the compressive capacity of the formwork during the pouring process and preventing the formwork system from deforming or undergoing overall displacement during the concrete pouring process. And by driving the first hydraulic push cylinder 11, the extended formwork 12 is moved outwards to increase the support area, thereby further improving the stability of the formwork system. On one side of the top of the base 1 are symmetrically arranged support mechanisms.

[0027] In the present utility model, preferably, moving wheels 2 are fixedly connected to the four corners at the bottom of the base 1, and a distribution box 19 is fixedly connected to the top of the base 1.

[0028] In the present utility model, preferably, the pedestal 3 is fixedly connected to the base 1 by bolts.

A limit seat 7 is provided at the top of the sleeve 5 to limit the lifting range of the lifting column 6. When the first motor 9 is started, the threaded connection between the screw rod 8 and the lifting column 6 causes the lifting column 6 and the support formwork 10 to move up and down to adapt to roof formworks of different heights.

The guide rods 18 ensure the linear movement of the bracket 15 and prevent deviation. During the whole process, the compressive capacity of the formwork system is improved, effectively preventing the formwork system from deforming or undergoing overall displacement during the concrete pouring process. Through this design, the formwork of the present utility model can adapt to the construction requirements of large-slope concrete structure roofs, improving construction efficiency and safety.
