Among high-formwork accidents, formwork collapse is one of the most common and hazardous incidents, accounting for approximately 30% to 50% of major construction accidents. To prevent such accidents, the following key points must be addressed:
1.Formwork System Must Withstand Heavy Horizontal Loads：Horizontal forces such as those from concrete pump pipelines and wind loads must be considered. If these exceed the formwork’s bearing capacity, horizontal layer collapse may occur.
2.Proper Installation of Vertical, Horizontal, and Diagonal Bracing：Improper bracing arrangement can lead to uneven load distribution or localized overloading, increasing the risk of collapse.
3.Avoid Excessive Spacing Between Vertical Supports：Overly large step distances between supports drastically reduce the formwork’s overall load-bearing capacity. If concrete is poured under such conditions, collapse is highly likely.
4.Impact of Surrounding Structures and Site Complexity：Special attention must be paid to nearby buildings and environmental factors, particularly in excavation zones, as they can affect overall site stability.
By implementing these preventive measures, the occurrence of high-formwork accidents can be significantly reduced, ensuring safer construction operations.
