Lightweight formwork for residential projects
By Chris Sleight24 January 2011
Among the displays on Peri's stand will be its Uno formwork system, which is particularly suited to housing products where the same layout has to be repeated time after time. It is a light-weight, manually handled system, with all components made out of aluminium, and the only tools required are a hammer and wrench.
Wall lengths can be adjusted to suit the project, while wall thicknesses can be changed in 10 mm increments. Re-useable ties take care of the anchoring work, and these are installed on one side only. In addition to mechanical couplings designed to make striking the formwork as easy as possible, the slab elements feature a drophead to allow early striking, reducing the number of forms required on site for any given project.
Other formwork systems on display will include the Liwa lightweight panels, which are designed for use without a crane. They come in heights of 0.75 m, 1.50 m, 2.50 m and 3.00m, and widths of 0.25 m, 0.40 m, 0.50 m, 0.60 m and 0.75 m, and are designed for the construction of walls and foundations from 150 mm to 400 mm thick.
The Lico lightweight column formwork meanwhile is for rectangular columns from 200 mm to 600 mm thick. Again, the formwork can be moved by hand and units measuring 0.50 m, 1.00 m and 3.00m in height are available.
Also on display will be the company's Ergo props and Multiflex girder slab formwork.
