Product information

Permanent formwork:

  • The perfect solution for saving time and money when casting suspended concrete floors.

Proprietary Q-Lock® interlocking system. 

  • Fastest permanent formwork construction in the industry.
  • The Most secure connection between panels.
  • No additional clips are required.
  • Suitable for installation by semi-skilled labour.

Features:

  • Q-Lock® saves time on erection.
  • Q-Lock® supports the weight of wet concrete and construction load.
  • Q-Lock® Completely removes the need for temporary formwork.
  • No need for additional reinforcing steel when used according to the supplied loading tables. Ref 193 Mesh is required only to prevent cracking.
  • Suitable for use on steel, brick, and concrete structures.
  • Q-Lock® greatly reduces the number of temporary propping supports required.
  • Q-Lock® is easy to transport, handle, and install. 

Product material specification:

  • ISQ 230 grade Z200 Galvanized steel.

Design Information:

  • Q-Lock® panels can be used in conjunction with additional reinforcement to increase the moment of resistance.
  • Design Methods for slabs where Q-Lock® is used is the same as for conventional slab design with the Q-Lock® panels providing the tensile reinforcement.
  • The propping distances for Q-Lock® vary from 1.5M to 4.0M depending on the profile and material thickness. Unpropped distances are indicated in our loading tables.
  • The calculations are based on the Limited State Method (SANS 10100-1: 2000)
  • SA Designs No A2016 / 00936 and F2016 / 00937

Product range:

The product range consists of a standard 260mm x 50mm profile complimented by an additional range of available profiles in four different material thicknesses to suit client needs.

Q-Lock profiles can be manufactured to any requirement within a 404mm girth of material.

For quick reference and convenience, this brochure contains loading tables for the most commonly used profiles across all material thicknesses.

Notes

  1. Loads in green are determined by bond.
  2. Loads in pink are determined by moment of resistance.
  3. Loads in blue are determined by deflection under total load (span/ 250) or deflection under live load (span/ 350) but equal to or less than 20mm.
  4. Bold red line indicates maximum span/depth ratio @ 30.

Installation

Q-Lock® panels are designed to interlock and require no further fastening between panels.

 Steel:

  • When installed onto a steel structure the panels are secured to the structure on every beam in every Q-Lock® pan by means of a suitable self-drilling or hammer drive screw or nail.
  • A minimum 50mm end bearing is required for installation onto a steel structure.

Concrete:

  • When installed onto a concrete or brick structure the lower lip of any flashing is secured by means of nail-in or similar concrete fasteners at 500mm centers.
  • The Q-Lock® panels do not require any fastening to a concrete or brick structure.
  • A minimum 75mm end bearing is required for installation onto concrete.

Please note: Final design is to be created and verified by a suitably qualified structural or civil engineer.
