Steel formwork commonly uses various types of formwork anchors to secure the formwork to the structure and ensure construction process stability and safety. Examples of these formwork anchors include:
1. Wedge Anchor: This anchor has a threaded rod with a wedge-shaped end. By inserting it into a pre-drilled hole in the concrete structure and tightening a nut on the threaded end, a strong grip is formed. It is commonly used to secure formwork to concrete walls or slabs.
2. Screw Anchor: Also known as self-tapping anchors, these anchors are designed for use in softer materials like wood or light-gauge steel. They have a threaded body that can be screwed into the material, providing a secure connection for the formwork. Screw anchors are popular for temporary formwork applications due to their easy installation and removal.
3. Hook Anchor: This hook-shaped anchor is typically embedded into the concrete structure during the pouring process. The formwork is then attached to the hook using bolts or fasteners, creating a strong and reliable connection. Hook anchors are commonly used in applications with high loads or lateral forces.
4. Swift Lift Anchor: Specifically designed for lifting and handling precast concrete elements, including steel formwork, these anchors are embedded into the structure during pouring. They provide a safe and efficient method for lifting and positioning the formwork.
5. Plate Anchor: Plate anchors consist of a flat plate with holes for bolts or fasteners. They are versatile and commonly used in steel formwork systems to secure the formwork to the structure. Plate anchors can be easily adjusted or relocated as needed.
6. Chemical Anchor: Chemical anchors are used when a strong and permanent connection is required. They consist of a resin or adhesive injected into a pre-drilled hole in the concrete structure. The steel formwork is then attached to the chemical anchor, creating a secure bond.
Each type of formwork anchor has unique advantages and is suitable for different applications. Factors such as the type of structure, load requirements, and duration of use should be considered when selecting the appropriate anchor and ensuring proper installation for the safety and stability of the formwork system.
There are several types of formwork anchors that are commonly used in steel formwork. These anchors are essential for securing the formwork to the structure and ensuring the stability and safety of the construction process. Some of the different types of formwork anchors used in steel formwork include:
1. Wedge Anchor: This type of anchor consists of a threaded rod with a wedge-shaped end. It is inserted into a pre-drilled hole in the concrete structure and secured by tightening a nut on the threaded end. The wedge anchor provides a strong grip and is commonly used for securing formwork to concrete walls or slabs.
2. Screw Anchor: Screw anchors, also known as self-tapping anchors, are designed for use in softer materials such as wood or light-gauge steel. They have a threaded body that is screwed into the material, providing a secure connection for the formwork. Screw anchors are easy to install and remove, making them a popular choice for temporary formwork applications.
3. Hook Anchor: This type of anchor is shaped like a hook and is typically embedded into the concrete structure during the pouring process. The formwork is then attached to the hook using bolts or other fasteners. Hook anchors provide a strong and reliable connection and are commonly used in applications where high loads or lateral forces are expected.
4. Swift Lift Anchor: Swift lift anchors are specifically designed for lifting and handling precast concrete elements, including steel formwork. These anchors are embedded into the structure during the pouring process and provide a safe and efficient method for lifting and positioning the formwork.
5. Plate Anchor: Plate anchors consist of a flat plate with holes for bolts or other fasteners. They are commonly used in steel formwork systems to secure the formwork to the structure. Plate anchors are versatile and can be easily adjusted or relocated as needed.

Each type of formwork anchor has its own unique advantages and is suitable for different applications. The choice of anchor will depend on factors such as the type of structure, the load requirements, and the duration of use. It is important to select the appropriate anchor and ensure proper installation to ensure the safety and stability of the formwork system.
There are several types of formwork anchors commonly used in steel formwork, including wedge anchors, sleeve anchors, and through-bolt anchors. Wedge anchors are inserted into pre-drilled holes in the steel formwork and are tightened with a wrench to secure the formwork in place. Sleeve anchors are similar to wedge anchors but have a sleeve that expands against the sides of the hole to provide additional stability. Through-bolt anchors consist of a threaded rod that passes through the formwork and is secured with a nut on the opposite side. These anchors offer a strong and reliable connection for steel formwork.
