The implementation of the template engineering is an important procedure for ensuring the quality and construction safety of concrete engineering, accelerating the construction progress and reducing the engineering cost. For the light steel truss system, steel columns and steel beam members are generally adopted, and the formwork engineering is the same procedures of manufacturing or selecting, positioning, supporting, dismantling and the like of the formwork, namely, the concrete poured inside is enclosed by the formwork, and the formwork is dismantled after the concrete in the interior is molded and solidified to reach the specified form dismantling strength. In general, the construction process is complicated, the occupied labor force is more, the cost is higher, and the construction period is longer.
