What is the Cintec Anchor
The Cintec Anchor System is a versatile method of structural reinforcement that is tailored to meet the specific strengthening and repair requirements of individual projects. Cintec anchors are used in historical buildings, masonry bridges, monument repair, high rise building, retaining walls, and harbor walls. These are just some of the areas a Cintec anchor can be used. Cintec anchors can stabilize and strengthen an un-reinforced masonry structure with out the need of external and internal steel bracing.
Research in the 1960s revealed that the construction industry needed an improved fixing system. Thus, the CINTEC Designed Anchor System was developed which meets the following objectives:
- Easily fixed, even in weak substrates.
- Easily used in poor quality materials and in bridging cavities.
- Sympathetic with existing structures - cementitious based.
- Versatile.
- Easily designed for differing applications by designers.
- Permanent.
- Capable of rapid manufacture.
The technical embodiment is simple in that the main steel body of the anchor is completely surrounded by a fabric sock.
The anchor is then located in an oversized drill hole joining the materials to be anchored together. Fluid grout is then injected under pressure through the middle of the anchor, until it reaches the remote end. There, it passes through a series of grout flood holes into the fabric sock. The entire assembly inflates like a balloon under the pressure.
The excess milk of the grout and bonding agent passes through the fabric sock, both fixing and providing a mechanical bond to the parent material. Variation in the size and shape of the individual components enable the basic method to be extended to meet the designer's requirements.
