Which structural member is crucial for providing lateral support in formwork?

• A. Wall panels
• B. Wales
• C. Shoring
• D. Reinforcement bars

Answer: (B)

Wales are essential structural members used in formwork to provide lateral support. Their primary function is to help distribute the loads transferred from the concrete and the formwork system, thereby maintaining the stability and integrity of the formwork structure during the pouring process and while the concrete sets. Wales run horizontally across the formwork system and are typically secured to vertical components, such as studs, which together resist lateral forces and prevent buckling or movement.

While wall panels are critical components of the formwork itself, they do not provide lateral bracing. Shoring provides vertical support to hold up the formwork but does not engage laterally. Reinforcement bars serve to strengthen the concrete after it has set but are not involved in supporting the formwork structure itself. Understanding the role of wales helps in ensuring safe and effective formwork design, which is fundamental in construction practices.
