In the actual construction process, although its layout is flexible and construction is convenient, there are some disadvantages as follows:

1. The amount of materials used is large, which is relatively time-consuming and labor-intensive;

2. The beam-slab support member (generally supporting φ48 steel pipe) is weak in strength, resulting in a relatively high density of vertical rods (generally arranged as 1.2m×0.9m/1.2m/1.5m). During construction inspection, the vertical rod density The impact on the traffic of operators and inspectors is large;

3. The strength stress of the vertical rod of the entire formwork frame is relatively small, and the strength of the material cannot be fully utilized. Generally, the utilization rate of the vertical rod strength is less than 50%, especially in general residential buildings;
