1. Formwork Ties

Formwork ties are essential accessories used to hold different form panels in place during concrete pouring and curing. Utilizing a variety of materials such as steel or plastic, these ties help maintain the proper dimensions and positioning of forms to ensure the safety and structural integrity of the concrete structure. On average, using high-quality formwork ties can prevent up to 90% of potential structural failures.

Benefits of Using Formwork Ties

By maintaining accurate formwork spacing, these ties significantly reduce the risk of deformation, ensuring that the finished concrete meets all specifications.

2. Brackets

Brackets provide support and stabilization to formwork structures, especially in larger projects where extra support is necessary. Typically made from strong materials, they are designed to bear heavy loads while maintaining form alignment.

Types of Brackets

  • Adjustable Brackets
  • Fixed Brackets

3. Formwork Screws

Screws used in formwork applications play a crucial role in connecting different form elements securely. They are engineered to withstand high tension and are available in various sizes to accommodate different formwork designs.

How to Choose the Right Screws

Consider the load-bearing requirements and environmental conditions when selecting the appropriate screws for your formwork project.

4. Shoring Accessories

Shoring accessories are critical for supporting formwork and concrete during the curing phase. These accessories ensure that the weight of wet concrete does not collapse the formwork.

Key Shoring Components

  • Props
  • Stacks
  • Adjustment screws

5. Spacers

Spacers are used to maintain the correct cover for rebar inside the concrete. This functionality is vital for structural durability and preventing corrosion of the reinforcing steel.

Spacer Types

Plastic and metal spacers are the most common types used, each serving specific environments based on the project’s requirements.

6. Formwork Frames

Frames form the backbone of any concrete casting operation. These pre-fabricated structures allow for quick assembly and disassembly, making them ideal for projects requiring repetitive casting patterns.

Advantages of Using Formwork Frames

Type Advantages
Steel Frames Durable and reusable
Aluminum Frames Lightweight and easy to handle

7. Stripping Tools

Stripping tools are essential for the safe removal of formwork after the concrete has cured. These tools ensure that the process is smooth, reducing the risk of damage to the newly formed concrete.

Choosing Stripping Tools

Select stripping tools based on the formwork type and the complexity of the design to ensure efficient and safe removal.

In conclusion, understanding the common types of Formwork accessories used in concrete construction can lead to significant improvements in overall project outcomes. Proper selection and usage of these accessories not only enhance safety but also contribute to the structural integrity and longevity of concrete structures.
