Steel formwork utilizes various types of ties to meet the specific needs of each construction project. The commonly employed tie options include:
1. Snap Ties: This fundamental and widely adopted tie type consists of a rod and a flat plate connected by a snap tie wedge. Snap ties securely fasten formwork panels for straight walls.
2. Coil Ties: These ties resemble snap ties but possess a more flexible design. Comprising a rod with a coil at one end and a flat plate at the other, coil ties are ideal for curved or irregularly shaped walls due to their easy installation and removal capabilities.
3. She-Bolts: She-bolts are threaded rods equipped with a flat plate and a nut. They serve to connect steel formwork panels and are commonly utilized for large panels or when supporting high loads is necessary.
4. Tie Rods: Tie rods are employed to secure formwork panels. They consist of lengthy threaded rods passing through the panels and are fastened with nuts and washers on both ends. Tie rods are often used in conjunction with other tie types to enhance formwork stability and support.
5. Wing Nuts: Wing nuts work in tandem with tie rods to firmly secure formwork panels. Their wing-shaped design allows for effortless manual tightening and loosening without the need for additional tools. Wing nuts are frequently utilized for vertical formwork applications.
6. Cone Anchors: Cone anchors are instrumental in anchoring the formwork system to the concrete structure. They consist of a cone-shaped anchor attached to a threaded rod, which is inserted into a pre-drilled hole in the concrete. Cone anchors establish a robust and dependable connection between the formwork and the concrete.
These examples represent only a fraction of the diverse ties employed in steel formwork. Selecting the appropriate tie system depends on variables such as formwork shape and size, load requirements, and the specific construction project. It is crucial to consult with a structural engineer or formwork expert to determine the most suitable tie system for a given application.
There are several different types of ties used with steel formwork, depending on the specific requirements of the construction project. Some of the commonly used types of ties include:
1. Snap Ties: These are the most basic and widely used type of ties. They consist of two parts, a rod and a flat plate, which are connected together using a snap tie wedge. Snap ties are typically used for straight walls and provide a secure connection between the formwork panels.
2. Coil Ties: Coil ties are similar to snap ties, but they have a more flexible design. They consist of a rod with a coil at one end and a flat plate at the other. The coil allows for easy installation and removal of the tie, making it suitable for curved or irregularly shaped walls.
3. She-Bolts: She-bolts are used for connecting steel formwork panels together. They are threaded rods with a flat plate at one end and a nut at the other. She-bolts provide a strong connection and are commonly used for large formwork panels or when high loads need to be supported.
4. Tie Rods: Tie rods are used for securing formwork panels together. They consist of long threaded rods that pass through the formwork panels and are secured with nuts and washers on both ends. Tie rods are commonly used in conjunction with other types of ties to provide additional support and stability to the formwork system.
5. Wing Nuts: Wing nuts are used in combination with tie rods to secure the formwork panels in place. They have a wing-like design that allows for easy tightening and loosening by hand, without the need for additional tools. Wing nuts are commonly used in vertical formwork applications.
6. Cone Anchors: Cone anchors are used to secure the formwork system to the concrete structure. They consist of a cone-shaped anchor with a threaded rod, which is inserted into a pre-drilled hole in the concrete. Cone anchors provide a strong and reliable connection between the formwork and the concrete.
These are just a few examples of the different types of ties used with steel formwork. The selection of the appropriate tie depends on factors such as the shape and size of the formwork, the load requirements, and the specific construction project. It is important to consult with a structural engineer or formwork expert to determine the most suitable tie system for a particular application.
There are several types of ties commonly used with steel formwork, including snap ties, taper ties, she-bolts, wedge bolts, and pins. These ties help secure the formwork panels together and ensure the stability and strength of the structure being formed.
