MAXIMO panel formwork:
One-sided operability shortens construction time
The new PERI MAXIMO wall formwork system created a tremendous amount of interest with visitors to this year´s bauma trade fair in Munich. With the MAXIMO, a new generation of panel formwork was presented which combines the insights and findings gained over many years from previous panel formwork systems as well as offering additional advantages.
For almost two decades now, the TRIO panel formwork with the optimized BFD alignment coupler has demonstrated its speed and versatile functionality – and with the introduction of the TRIO Housing, the handling was improved even more through the ties being fitted from one side only, resulting in substantially reduced shuttering times. The new MAXIMO has been designed to include both these outstanding product features. In addition, the centrically-positioned tie points in all element sizes mean that concrete surfaces with attractive architecturally-designed tie and joint arrangements can also be created.
These advantages match the requirements of numerous building contractors such as those of Mayer Construction, a company which is based in the town of Ruhpolding in the state of Bavaria. For their wide range of building projects in the areas of housing development, industrial construction as well as civil and underground engineering, the speed and the flexibility of the MAXIMO is particularly in demand. On the one hand, a wall formwork system should be quick and easy to use and, on the other, it must exhibit multi-purpose usability for reinforced concrete walls, foundations, columns and beams.
Mayer´s fourth use of the MAXIMO formwork involved forming the reinforced concrete walls of a rectangular-shaped cellar for a semi-detached house with an 11 x 14 metre ground plan. Instead of having to set aside the usual four days to complete the job, foreman Enrico Schirmer required only three days using MAXIMO - with a formwork crew of only three men. Schirmer attributes the time-savings achieved quite clearly to the fact that the MAXIMO formwork must only be anchored from one side. As it happens, due to the newly developed, conical tie system, spacer tubes are no longer required. This keeps site movements to an absolute minimum and saves on resources as well as time. Very few different system components, suited for construction sites and the rigid corner design also contribute to faster forming.
A positive side-effect is also the fact that using the MAXIMO with its centrically-arranged tie points throughout always results in a neat tie and joint arrangement. Because all tie positions are filled, no unsightly impressions of PVC plugs appear on the concrete finish itself. Furthermore, the systematized and clear tie point specifications lead to error-free forming – this additionally accelerates the shuttering times. "The MAXIMO is unbeatable", said Enrico Schirmer, and added: "I am very impressed and totally convinced about the system".

“As formwork operations can take place from the inside, we only need three men on site and, in addition, construction time for the basement walls is reduced from four to three days. Concreting results with the neat tie and joint arrangement has architectural concrete quality and corresponds to the increased requirements. The MAXIMO is unbeatable – I am very impressed and totally convinced about the system."
