As an optimal way, the method for adjusting the formwork also includes the formwork removal adjustment method. When the formwork is removed, the pull bolts (or wall bolts) and node connecting members should be removed first, and the large formwork should be adjusted backwards by using diagonal braces (first support). Lean and break away from concrete walls.

The beneficial effects of the present invention are:

1. This construction method has simple process, fast construction speed, good engineering quality, good structural integrity and seismic performance, and the concrete surface is smooth and smooth, which can reduce the amount of wet plastering work for decoration;

2. The format of this kind of process template can be made very large, which can reduce the number of tower cranes and workers' operating time, shorten the construction period, reduce labor intensity, and save production costs;

3. This method has a short construction period. It is a quick-release formwork system. The normal construction of a set of formwork can reach one floor in four days, and the assembly line construction can be better launched, which greatly improves the construction progress and saves management costs.
