Conalu aluminium panel formwork


The Conalu panel formwork is conceived and produced by Construx. It is a multipurpose modular shuttering system for on-site concrete jobs 

This shuttering system belongs to the category of manually erectable aluminium panel systems and is suitable to be used on every site where concrete walls, columns or beams need to be poured in a cost-effective way. 

Despite their limited weight, the Conalu panels are rigid and have a high resistance, between 60kN/m² and 80kN/m², depending on the type of panel. Through total quality management, in design, production and logistics, Construx guarantees a permanent high quality.

Composition of the Conalu panels:

  • Aluminium frame 
  • 18mm plywood with a 220g/m² phenol coating
  • Plywood screwed from behind
  • Profiled sides

Requirements of the Conalu system:

  • Rigid and solid
  • Easy and ergonomic
  • Designed and calculated according to applicable standards
  • In-house production, controlled and certified

Specifications of the Conalu system:

  • Modular panel formwork system
  • Panel thickness 120mm
  • Wide range of panel sizes
  • Limited number of parts
  • High pressure resistance 60kN/m² to 80kN/m²
  • Long life expectancy
  • Corner and column setup with 10mm increments
  • Can be combined with the Tricon panel formwork

Conalu panel types:

  • Wall panels: standard panel with 4 tie holes
  • Wall panels with extra holes at 250mm from the side profiles: when fitted sideways, these panels can be tied above the waterproofing
  • Column panels: provided with an extra hole pattern every 50mm, adjustable with 10mm increments by using an adjuster nut, to use in corners, wall connections, as end panels and to make column boxes
  • Adjacent panels: identical structure as the column panels but without the hole pattern, to be used in corners and as an infill
  • Big size panels: widths of 2000mm, 2500mm and 3000mm, always fitted with extra holes for easy use in both ways
  • Fixed inside and outside corner panels: to make 90° angles 
  • Articulating inside and outside corner panels: to make sharp and blunt angles 
  • Corner columns: combination of inside corner panel and column panel, to be used where columns are integrated in a wall

Utilization of the Conalu formwork:

  • Connecting the panels takes place with the Conalu clamps, only 2 per joint when using panels of 2650mm
  • Compensation walers with different lengths serve to reinforce and align joints between panels
  • Variable Conalu clamps to be used with infills of up to 150mm
  • Every panel is fitted left and right with 2 tie holes
  • Infills of 50, 60, 100mm wide are made in aluminium, fitted with variable Conalu clamps and aligned with compensation walers
  • Infills larger than 150mm are made with timber Conalu profiles, coupled with standard Conalu clamps and aligned with compensation walers, the tie bars go through these compensation walers
  • 90° angles are made by using an inside corner panel on the inside and an outside corner panel or a combination of a column panel and an adjacent panel on the outside
  • Sharp and blunt corners are made by using articulating corner panels that can be aligned with articulating compensation walers
  • Conventional columns are made by positioning 2 panels opposite to each other and by making the 2 other sides in timber
  • With 4 column panels in a  hit-and-miss setup, columns can be made with 10mm increments, the maximum section made with the 1000mm wide panels is 850mm x 850mm
  • Single-sided walls are made by using brace frames
