In the construction process, formwork installation is a key procedure in concrete structure engineering. During formwork installation, professional formwork support devices are required. Existing support devices use formwork plus steel pipe frame support. This support method involves a large amount of work, requires high worker skill, is time-consuming and labor-intensive, and has low efficiency. In addition, traditional formwork is not easy to adjust in height or width between formwork sections during installation, resulting in a large workload and low practicality. Therefore, we propose an adjustable concrete formwork support device. Summary of the Invention
