RoofSafe Anchors for PVC membrane roof systems
Anchors are constructed from mild steel and have a protective corrosion resistant coating. In addition, the base plates are coated with an approved PVC solution to enable the roofing contractor to directly weld the PVC roof membrane to them. An approved PVC Top Hat is also supplied. The top hat can in turn, be welded to the roof membrane to provide a neat and secure waterproofing detail.
The use of this product simplifies the waterproofing process and ensures the anchor has long term resistance to water ingress. This product was designed with support from roofing manufacturers to meet with the requirements of their guarantees.
Only approved waterproofing details should be used and detailing work must be carried out by an authorised roofing contractor. Base plates are completely flat to make sealing easier and have recessed fixing points to protect the roof membrane from becoming damaged.
Very importantly, no elements of the anchor are exposed to the environment after installation, ensuring long term corrosion resistance and anchor performance. Anchors stand 150mm above the roof surface, complying with industry standards for waterproofing.
This anchor can be used on the following roof constructions:
- Concrete
- Hollow concrete
- Metal Deck
- Plywood
Fitting the anchors
The anchor can be fitted to metal decking, plywood or concrete roof constructions from the top of the roof using M8 toggle clamps, mechanical fixings or stud, provided with anti-compression spacers. The length of the toggle bolt can be increased to allow for use in constructions with deep insulation.
The number and size of the toggle clamps/stud have been calculated to counter the overturning moment applied by the anchor in the first stage of activation and resist the shear load in the second stage of activation when the energy absorber deploys.
What roof system can the anchors be fitted to?
Anchors can only be installed on roof systems that have been validated as capable of supporting the distributed loads applied in the event of a fall. Uniline offer alternative solutions for roofs which are not suitable.
This predictable distributed load can be used to validate the roof systems suitability for use as a structural anchor. In the case of built up flat roofing systems, the distributed load can vary depending upon the depth of the insulation and can range from 0.5kN/sq.m to 4.0kN/sq.m where insulation is 300mm deep.
Which cable systems will work with the anchors?
The anchors are used for integrating Uniline’s cable fall protection systems into your building, thereby facilitating safe access.
There are four types available: End Anchors (Type A), Corner Anchors (Type B), Variable Anchors (Type C) and Intermediate Anchors (Type D).
The type D anchor may also be used as a single point anchor. (EN795 Class A2)
For further information, please contact Uniline’s Technical Department.
Use with environmentally friendly roofing
Use of Uniline’s pre-engineered weather proofing detail enables the anchor to be used in conjunction with Green Roofing Systems. The sedum element of the roof construction can be installed around the anchor without any fear of water penetration through the sealing detail.
