Product details
     
    A rigid, usually circular, component placed over a bundle of prestressing strands at the end of a tendon, and that transfers the strand forces directly to the anchor component via tapered wedges located within its internal conical recess.
    The flat anchor is the first of two components that make up the flat slab anchorage, which offers a cost-effective and efficient solution to bonded post-tensioning in the construction industry. Anchors are used to anchor the tendons into the concrete while terminating or joining two tendons. Main function of anchorage is to transfer the stressing force to the concrete once the stressing process is completed.
    The flat anchor is also designed to hold both the ducting and grout tube snuggly.
Our products are extensively applied in many projects such as highways, railways, bridges, building constructions, hydroelectric projects, TV towers, large containers, rock anchors and ground anchors. 

                                                    



Quality Control
     
      Anchors are used to anchor the tendons into the concrete while terminating or joining two tendons. Main function of anchorage is to transfer the stressing force to the concrete once the stressing process is completed.
      So quality control is one of the most important process in production. We insist that 100% inspection before shipment and ensure parts without any flaws when sending out.


Application

1.The installation of post tensioning tendons in the concrete and stressing it requires skilled labour and a personnel who are certified in doing the tensioning works.
2.The tendons are laid down along with the conventional rebars. The position of laying of the tendons is decided by the engineer. These tendons are encased in plastic or steel ducts so that they do not come in contact with the water in concrete.
3.One end of the tendons are anchored with the help of anchor and the other end is left open with plastic pocket former, where the tendons are stressed. Couplers are used in between if  any construction joint is formed.
4.Concrete is poured and the alignment of these tendons are taken care of so as to let their positions unaltered.  Once after the concrete has achieved its 75% of strength , that is around 20 - 23 days, these tendons are stressed with the help of  stressing jacks.
5.The tensioning is done to a force equal to 80% of a strand's tensile strength. For a typical ?-inch grade 270 strand, the strand is tensioned to a force of 33,000 pounds. As the tensioning comes into effect, the steel gets elongated, and the concrete is compressed.
6.When the proper tensioning force is reached, the prestressing steel is anchored in place. The anchors are designed to provide a permanent mechanical connection, keeping the steel in tension, and the concrete in compression.
7.The extra tendons that are left out at one end are trimmed and non shrink grouting is put in the anchor pocket.
