Tri-Chem Concrete Anchor

All Safetor Tri-Chem Roof Anchors for concrete meet the requirements of the AS/NZS 1891.2:2001 Standard: Horizontal Lifeline and Rail Systems, and AS/NZS1891.4:2009 Standard: Industrial Fall Arrest Systems and Devices

Tri-Chem Concrete Anchor

This anchor is recommended for: fall-arrest, abseiling, and lifeline systems. 8 x M10 standard threaded anchor rods are used with HVU-Adhesive capsule anchor system.

Each Tri-Chem bolt must be load tested to 3kN before bolting mounting plate to concrete structure this would rate the attached anchor at 12kN to 21kN. (See 2nd picture)

Safetor height safety concrete anchor points have been designed to either be bolted through concrete walls, reinforced into concrete or be bolted to concrete surfaces using no less than eight chemset bolts. It has been proven that single bolted eyes are unreliable as a number of them have had a tendency to pull out when used.

Many things can cause them to fail like building movement due to earthquakes, cracking concrete, poor installation, load cell testing on a single bolt, and the concrete itself. Having the load shared by more than one attachment point you increase the safety factor. Our method of using eight attachment points on our Tri-Chem anchors increases our safety factor by 8 times the normal standard.

Ultimate Yield:

21kN parallel to mounting plate 2lkN away from mounting plate

Application as per AS/NZS1891.4:2009

  • 1 persons Free-Fall Arrest = 15kN
  • 2 persons Free-Fall Arrest = 21kN
  • 1 persons Abseil Anchor = 12kN

Coatings

Plascoat PPA 571 ES is resistant to stress cracking, adverse weather conditions, detergents, salt spray and typical airborne pollutants. The coating maintains excellent adhesion to the metal substrate without the need for a separate primer. The material also provides good abrasion and impact resistance.

Safety Factor

Physics is the scientific study of forces. In simple terms, the wheel on the standard car today has around five wheel studs and nuts this is so the load is shared evenly around the rim. Trucks have much larger tyres cars so they need bigger wheel studs, and a lot more of them to share the load around the rim. This is a similar principle to why we use eight mounting points on our anchor instead of one.

Warning

All these types of anchors must be cell load tested before use. Before installing any chemical anchors it is important to read and understand all the manufacturers recommendations on the correct use and procedures to install bolts.

Collins Corporation Ltd. recommend the use of HILTI products for the installation of concrete fixed anchors.
