The HeliFix PatchPin is based on the HeliFix DryFix technology which has been used for well over 20 years. It is further based on a spiral Stainless Steel twisted element being driven into a smaller hole in a substrate to obtain anchorage. For the purpose of a Wall Tie Pullout values are extremely important. Why the PatchPin works so well for concrete patching pins is that it is Stainless Steel and the twist provides maximum grip to the new patching material, the pin can be bent so Stainless Steel wire can be attached but Pullout not so much. If you look at the diagram you will see that when the PatchPin is installed at “alternate” angles they form an impediment which holds the patch in place as the pins are fixed by the substrate and the patch and cannot move. The only need for Pullout is to hold the PatchPin in for installation and attachment of the wire, after that no pullout is needed, only the geometry to hold it, and the concrete patch, in place. This is the misconception that most engineers have, that the performance of the PatchPin is based on Pullout, which of course, being in concrete always exceeds 400 pounds anyway.
As we get ready to work in yet another Elevator Shaft project I just wanted to show you how easy a Cement Based Structural Stucco us to apply, even in the most difficult conditions. For further information link to – https://www.conspec-rep.com/contact-us/ –
Cintec Cement Based Socked Anchors can be any length, any steel size, including tubular, round or square, installed at any angle, including overhead and provide a FIREPROOF anchor, especially important in the case of fire in Cavity Walls. Penetration of Steel beams or columns for attachment of any material, including stone and terracotta of any size or weight, only dependent on the substrates ability to support it.
CINTEC PROVIDES CALCULATIONS TO THE EOR, STRUCTURAL ENGINEER.
Socked based cement anchors, whether HeliFix or Cintec, are easier to install than resin anchors with almost no waste compared to resin anchors and are fireproof. Installation shown is using plastics inserts for a battery operated bulk cement gun but can be used with just a regular battery or even air operated gun using no sleeves and just filling the tube itself. For high volume projects or long anchors, a pressure pot can be used to facilitate the larger volumes and for the greatest efficiency a peristaltic, continuous feed pump is ideal.
PORTABLE CEMENT BULK GUN
Considering all the concerns regarding cavity walls and the need for Controlled Inspection bases solely on Resin Based Anchors consider the ease of installation and Fireproof property of a cement based anchor. Cintec anchors can be any size and custom made for things like Window Installation in Rubble Walls or Attachment of face wall to steel beams or columns.
THE PROBLEM – Hotel need to provide 200 pipe penetrations through the Speedtile arch which was a major concern as it would cause distress to the stability of the individual tiles and the arch.
RUREGOLD SOLUTION – Place a 2 foot by 2 foot Ruregold “Patch” at each penetration to strengthen the face of the Speedtile prior to diamond drilling the penetrations from the bottom, which would allow for ease of penetration by drilling without damage to the tile.
When fixing a window in a rubble wall which has inconsistent infill many time mechanical and even resin anchors will nor perform well or consistently. It is in these conditions where a cement based socked anchor provides the ideal solution to cover any voids or cavities. Even in Speedtile or CMU walls this system provides maximum anchorage in a fire rated anchor and is easily installed.
