The flexible formwork system
What is Syflex®
What is Syflex®?
With our flexible formwork system Syflex®, you can easily make straight lines, curves and corners. Syflex® is the optimum solution for base slab, edge and strip foundation formwork.
Increasing demands are made in terms of the shape of concrete. Formwork for curves always presents a problem in this respect.
Conventional formwork systems for this task are very labourintensive, costly and not very flexible. Bulky and heavy wooden planks demand time and have a detrimental effect on the work process, and special formwork is costly. The Syflex® formwork system means there is a solution available which is easy to handle, as it is only one third of the weight of comparable wooden formwork, and can be assembled without hoisting devices within a very short time. The system enables formation of straight lines, curves and corners with a minimum of effort and in addition can be reused many times over.
Syflex® gives you concrete in almost any shape you want. However, Syflex® is not just the best possible way of making formwork for foundations, the system also has a proven track record in road building and in garden and landscape architecture. The multiple application options make Syflex® a genuine allrounder on the formwork market.
Why to use Syflex®?
The formwork boards can be extended using connections, both in straight lines and in flexible shapes. System eccentrics then ensure quick fixation to pegs, planks or mounting brackets which have been driven in. This configuration is also used for the vertical connection of the formwork boards which stand one on top of the other.
- low weight – only about 1/3 weight of comparable timber shuttering
- can be used many times again
- easy mounting and disassembly
- short working time
- individual shaping: shuttering of straight lines, curves and corners
- curves can be shaped up to 1 metre radius, memory effect
- light and very robust material at the same time
- eccentrics allow various types of fastening
- great saving of costs
- levelling is accurate to a millimetre, for concrete stripping
Syflex®. Light. Simple. Quick.
You can fix the Syflex formwork elements with pegs, planks or mounting brackets.
The spacing of the fixation is dictated by the condition of the substrate and the maximum deflection tolerated by the formwork elements. In order to achieve greater profile rigidity, there is the possibility of bracing the formwork element with a galvanised Ushaped profile in a hollow chamber.
After fitting the bracing (peg, plank, formwork angle or similar), the Syflex® formwork profile is leaned against the bracing and fastened to it using the system eccentric. The Syflex® system eccentric is placed on theback of the formwork element for this purpose and screwed into the groove. The formwork element is fixed to the bracing by moving the eccentric lever.
To adjust the formwork to the exact height, the eccentrics are loosened again slightly and the formwork element is levelled to the appropriate height. Now tighten the eccentric up again. Finished!
For external corners, a saw cut of approx. 3 cm is made into the formwork profiles at the appropriate place on the rear and then they are simply bent.
For internal corners, a mitre cut of approx. 3 cm is made into the rear of the formwork profiles and then they are appropriately bent.
2 formwork elements are connected using 2 plastic tubes which are screwed into the profile.
The tubes are inserted half way into the first profile and tightened with a cordless screwdriver. The 1st formwork element is now inserted into the 2nd formwork element, pushed together and screwed tight. Finally, seal the joint with adhesive tape.
The Syflex® formwork system comprises the individual formwork profiles in heights of 10, 15, 20, 25 or 30 cm, along with the system eccentrics for fastening the formwork profiles onto the customer’s bracing. 2 formwork elements can be connected using plastic tubes which are screwed into the profile.
Syflex® generally pays for itself at the latest when it is used for the third time. When it is first used, there is an expenditure which is similar to that for conventional wooden shuttering. When it is used for the second time, the expenditure is equivalent to lost formwork and Syflex® already pays for itself when it is used for the third time. When used properly, it is possible to use it at least 20 times.
Calculation principles for the maximum deflection of the formwork elements: Most unfavourable assumption with regard to modulus of elasticity and configuration of the various profile heights, temperature 25°C, concrete B25. Pegs, planks or similar do not shift and are firmly anchored into the substrate.
