Eflex Square - A Furukawa Electric Product

Installing into Concrete Chambers

  1. Cut an opening in the chamber according to figure 1 (Advice PDF File: Furukawa Bell Block Installation Procedure)
  2. Cover the single opening on the inside of the chamber with a plate (or similar) and hold it in place with a wooden block/ spacer (or similar), while working.
  3. Ensure the area is free from dirt/ debris and apply epoxy putty (or similar) to the base of the opening and insert Bell Block ensuring that the side that has the diameter markings is on the outside.
  4. Fill the gap above the Bell Block with epoxy putty (or similar). It may be necessary to use a space to fill the gap if too large. Ensure that the Bell Block Connectors are free from putty to ensure a secure connection to EFLEX Square. If a watertight seal is necessary, apply epoxy putty around the edge of the block on both the inside and the outside of the chamber. Masking tape can be used to prevent concrete from entering the block connectors.

Installing Multiple Bell Blocks into Concrete Chambers

When installing a block directly above another, use epoxy putty (or similar) in between. Ensure that there are no gaps to maintain water tightness, if required. Ensure that the Connectors are free from putty to ensure a secure connection to EFLEX Square. Insert the Blocks ensuring that the side has the diameter markings is on the outside.

Installing into Concrete Chambers using Spacers

When using spacers to hold the Bell Block in place while work is close to completion, ensure that you insert the spacers next to the thickest section of the block to avoid unwanted damage.

For Installation in concrete (Tunnel example), please advice PDF File with Installation Procedure below.
