Product Information

Beams I tec 20 are formwork beams made of wood. They are intended for use in load-bearing towers and formwork.


Basic design concept

▪ Solid-web beam made of wood and wood-based materials pursuant to national technical approval n° Z-9.1-773.

▪ Spruce and birch plywood web; plies sorted by visual inspection and 100 % tested by the tensile loading test method (proof-loading). Plastic sheet on the broad faces of the flanges.

▪ Poplar-plywood web with grey web coating.

▪ Polyurethane end reinforcement

▪ 2 system holes at each beam end 


Features

High load capacity, achieved by innovative composite technology

▪ permitted bending moment M = 9.0 kNm

▪ permitted shear force Q = 20.0 kN

▪ rigidity E x I = 640 kNm²

▪ weight = 5.6 kg/lin.m

 

Save on equipment, thanks to optimized load capacity

▪ up to one-third fewer floor props on timber-beam slab formwork

▪ up to 30 percent fewer form-tie points on Wall formwork FF100 tec and Large-area formwork Top 100 tec

▪ 50 percent fewer primary beams in the superstructures of fully loaded load-bearing towers

 

More repeat uses, thanks to all-round protection

▪ extra-long lifespan, thanks to the proven 'top' beam-end reinforcement

▪ reduced close-out costs due to the I tec sheet that protects the whole length of the flanges


Surfaces

▪ Yellow varnish without wood preservatives.

▪ Grey plastic sheet on the broad faces of the flanges.

▪ Grey web coating.

Instructions for Use

For use in wall-formwork and slab-formwork systems, tunnel formwork, automatic climbing formwork, etc.

▪ These beams have the same dimensions as beams H20 but are approximately 80 % stronger, so the reduction in material quantities in slab and wall formwork is considerable.

▪ Together with the plastic sheet on the broad faces of the flanges, the polyurethane end reinforcement contributes to prolonging service life.

▪ Beam-flange markings in a 50 cm grid
