KOMBI systems are made of three primary modules, namely the support module, the platform module and the stair module. Each module is available in a variety of sizes which can then be adjusted.

Designing KombiKOMBI DESIGN PURPOSE

  • For use by construction workers, specialist trades and maintenance personnel.
  • Suited to plant and machinery access, inspections, assembly  work and general maintenance.
  • Stair system not suited to general public access covered under BCA and NCC codes and requirements.

KOMBI BILDA CONFIGURATOR

  • A cloud based 3D design tool built specifically to configure KOMBI systems.
  • Includes KOMBI proprietary design parameters.
  • Provides 3D model and front, top and side views.
  • Provides a schedule of components required to build the required system.

Designing Kombi

PROPRIETARY SYSTEM

  • KOMBI is an engineered and configured system.
  • A series of live load testing and calculated parameters have determined design outcomes.

DESIGN STANDARDS & CODES

  • KOMBI stair and platform systems are designed in accordance with AS1657 and AS/NZS 1170 under live load conditions.

System Assembly

POST SUPPORT ASSEMBLY

  • KOMBI post support structure is design to support a live load of 2.5kPa (250kg/m2).
  • KOMBI supports are available in three standard widths 610mm, 915mm and 1220mm. Custom widths can be manufactured.

 

Kombi Post Support Assembly

Installation Requirements

  • See configuration tables for set out of horizontal braces, bracing straps and lateral braces.
  • Lower horizontal brace struct KB520 is set at 150mm above bottom of post.

 

PLATFORM ASSEMBLY

  • KOMBI platforms are designed to support a live load of 2.5kPa (250kg/m2 distributed load).
  • KOMBI platforms are available in three standard external width dimensions 687mm, 992mm and 1297mm. Custom widths can be manufactured.
  • KOMBI platforms can be joined together to create larger decks where required.
  • For dead loads such as an aircon unit, pallets etc please consult with the Sayfa design team to confirm correct configuration.

Kombi Platform Assembly

 

Installation Requirements

  • Platform mesh aperture to be a maximum of 15mm where persons have access to or work beneath the platform. The GW334 narrow width deck to be used in this application.
  • Guardrail posts to be space dat a maximum of 2000mm centres.
  • Maximum dimensions between underside of handrail to top of kneerail is 450mm.
  • Platform toe board is required where an object could fall from the platform onto an area to which access by persons is a possibility. Maximum gap between toe board and deck is 10mm.

 

STAIR ASSEMBLY

  • KOMBI stairs are designed to support a load of 2.5kPa liveload (250kg/m2).
  • KOMBI stairs are designed to best suit a 40 degree angle however are suitable angles from 25 - 45 degrees.
  • KOMBI stairs are available in three standard widths: 610mm, 915mm & 1220mm. Custom widths can be manufactured.

 

Kombi Stair Assembly

Installation Requirements

  • Minimum inside distance between stair stringers to be not less than 600mm.
  • Clear space between handrails/kneerails to be no less than 550mm.
  • The number of treads in a flight must not be less than 2 or greater than 17.
  • Treads are allowed maximum of 5mm variation in spacing as per AS1657:2018.

Post Support Bracing Layout

  • Step 1:  Identify correct post height.
  • Step 2: Determine correct post support kit.
  • Step 3:  Assemble post support bracing as per tables below.

Post Support Span Table

  • KOMBI platforms are designed to support a live load of 2.5kPa (250kg/m2).
  • Calculations assume maximum flooring mass of 12kg/m2 (weight of guardrail and aluminium deck).
  • Allowance for floor vibration has not been taken into account in design.
  • Platform deflection has been based on two variables, frequent access (less deflection) and infrequent access (greater deflection). Table below shows post spacings based on above.
  • Lateral bracing is required as per configuration tables.

Lateral Brace Layout

Lateral Brace Installation

  • Kombi Lateral Bracing LayoutKOMBI platform proprietary design allows freestanding platforms of up to 6000mm.
  • Platforms above 3000mm require a horizontal brace mid span of the post in all bays.
  • For longer platforms exceeding triple span, up to 30m, lateral bracing is require in the first and last bay only.
  • For longer platforms from 30m - 50m, lateral bracing is required in the first, centre and last bay only.

Platform Configuration

Platform Set Out Guidelines

  • Platform cross supports positioned at 600mm centres.
  • Post supports positioned as close to end of platform as possible. (250mm max from outside edge of platform to centre of post.)

Stair Tread Calculator

KOMBI stairs can be adjusted to suit the required stair angle whilst allowing each individual tread to be leveled and spaced accordingly. This minimises on site measurement and fabrication requirements, resulting in significant time savings. OPEN CALCULATOR
