The Role of the Wedge Bolt

The wedge bolt is a critical component that enhances the performance of the X Flat Tie system. It features a tapered, wedge-shaped design that ensures a secure lock between the tie and the formwork panels. Key benefits include:

  • Secure Locking Mechanism: The wedge bolt, when driven into position, applies uniform pressure across the connection. This helps prevent any movement between the form panels during concrete placement.
  • Even Stress Distribution: Its unique design helps spread the load evenly, reducing the risk of localized stress that could lead to premature failure.
  • Quick and Efficient Assembly: The wedge bolt is engineered for ease of installation. Once the X Flat Tie is positioned, the wedge bolt is inserted to quickly lock the system into place.

Cunha reta

  • Aplicativo: Use the Straight Wedge when the formwork interface is flat. Its linear design provides an ideal, flush contact between the form panels.
  • Installation: Once the X Flat Tie and wedge bolt are installed, the Straight Wedge is inserted into the gap between the panels. Its design ensures that the panels are pressed together uniformly, eliminating any gaps that could compromise the integrity of the formwork.
  • Benefícios: This combination enhances the stability of the connection by ensuring that the force is applied evenly across the interface, resulting in a more reliable and secure setup.

Cunha curva

  • Aplicativo: The Curved Wedge is intended for formwork that features irregular or curved surfaces. Its contoured design accommodates non-linear edges and provides a more tailored fit.
  • Installation: After securing the X Flat Tie with the wedge bolt, the Curved Wedge is used in areas where the formwork does not lie flat. Its flexible contour adapts to the shape of the panel, ensuring a snug and secure connection.
  • Benefícios: The Curved Wedge prevents gaps in situations where a Straight Wedge might not achieve a complete seal. This improves overall system integrity and helps maintain the formwork’s alignment even under heavy loads.
