LD Standard Frame - 2 m

Big Foot Systems Ltd

The Big Foot Systems Light Duty range offers an array of solutions to support a variety of air handling units and air conditioning systems. Frame kits for most major manufacturer’s mini splits, heat pumps and VRV/ VRF units are available from stock.

Big Foot Splits Modular Frame:

For supporting air conditioning plant on flat roofs. As standard There are three basic modular frameworks available in 1, 2 and 3 m versions. The modular frameworks come with 305 mm or 450mm feet which are provided with anti-vibration mats. The frame is constructed from 40 x 40 mm box section. For heavier loads refer to Big Foot's HD range of products.

Big Foot VRV/ VRF Modular Frame:

Developed for the siting of most major manufacturer's VRV/ VRF systems. This lightweight and easily assembled Modular Frame system is quick to install and provides a robust and secure method of support.

Features/ benefits:

  • Non penetrative load management.
  • Cost effective, pre-fabricated support system.
  • Versatile modular frameworks.
  • Quick to install, robust and secure.
  • Optional independent warranty available.

Standards:

Constructed to:

  • BS8000-4: Workmanship on building sites. Code of practice for waterproofing.
  • BS6229: Code of practice for flat roofs with continuously supported coverings.

HD Beam 600 Adjustable

Big Foot Systems Ltd

The Big Foot Systems Heavy Duty range offers a robust cost effective support alternative to on-site concrete constructions. With minimal on-site assembly and easy positioning, the HD Cube and HD Beam products aid load distribution and are non-penetrative – helping to protect the roof finish.

Big Foot HD Cube:

The HD Cube offers a complete, efficient and robust solution for supporting heavier services on flat roofs. Ideal for the support of large plant rooms, chillers and large air handling units. The HD Cube provides a simplistic approach without the necessity of casting traditional concrete plinths early on in the construction project.

Big Foot HD Beam:

The HD Beam was developed as a lighter weight companion to the HD Cube. Typical applications include large chillers, large air handling units and heavy pipes and services. HD Beam is a robust but flexible solution where space may be limited, or there is a requirement to position directly over existing structural roof beams. With M24 stud built into both legs to accommodate roof falls, the requirement for additional adjustment is not usually needed. An optional, ‘quick fitting’ clamp kit ensures a rigid fix back to the services, or secondary steelwork.

Custom framework:

There are many situations at roof level that direct the designer away from a standard framework approach. Limited space, existing upstands, lightweight roofs and other services may all contribute to detailing an appropriate custom support solution. With the aid of technical surveyors and using ANSYS FEA software, Big Foot can offer custom made one-off solutions to meet the demanding environment present on some of today's roofs.

Wind analysis:

Big Foot Systems are currently using Computational Fluid Dynamics (CFD) software to calculate site specific wind load conditions. Using the industry-leading ANSYS wind profiling program, analysis is run based on the unit size, quantity and mass then calculated to determine over turning moment and destabilizing wind speed. Big Foot Systems CFD modelling is based on customer supplied information and available to customers dependent upon scheme size.

Features/ benefits:

  • Optional certified independent warranty.
  • In-house computer aided Design (CAD) service.
  • Non penetrative high load management system.
  • ANSYS Finite element analysis (FEA).
  • Load calculation service available.
  • Cost and time effective on-site installation.
  • Pre-fabricated for consistent and controlled installations.
  • Ensures greater project design flexibility.
  • Roof can be refurbished around installation.
  • Membrane warranty upheld due to no penetrations.

Standards:

Constructed to:

  • BS8000-4: Workmanship on building sites. Code of practice for waterproofing.
  • BS6229: Code of practice for flat roofs with continuously supported coverings.
