1 Slab formwork that combines safety with ecology French design

2 Slab formwork that combines safety with ecology The versatile TopDalle Eco system suits every type of building: offices, homes, retirement residences, hospitals, prisons, etc. Simple and quick to install, the,topdalle Eco system offers productivity of 30 m 2 / person/day at a height of 2.50 m. TopDalle Eco formwork, designed by the Alphi R&D Department, complies with the decree of September 2004 concerning falls from height, and meets the NF E and NF X standards concerning the risks of tripping, slipping, and falling objects, and the manual handling of loads.

3 TopDalle: safer, easier, more environment-friendly, more used. Safety Safety of personnel The work area is secured by full-surface Eco+ panels, preventing falls from height and the risk of tripping, slipping, or falling objects. Eco+ panels are installed and removed from floor level. With the Top Perche pole, formwork is installed and removed from ground level (less use of the mobile safety ladder). Increased stability The multi-support areas of the Eco+ panel, the continuous support extendable beam combined with the corner beam, provide optimum stability. Theft protection The chemical process patented by Alphi is a protective measure against the fraudulent recycling of aluminium beams. Ecology 100% "Green" Designed to limit CO 2 emissions, the Eco+ panel is made of 100% recycled and 100% recyclable aluminium. Short distribution channels The production method implemented by Alphi favours short distribution channels and operators in French industry, Transportation is limited to within France (distance between suppliers under 460 km). Fewer trucks Optimum packing has been achieved by limiting the thickness of the Eco+ panel and designing its shape for more compact stacking. Trucks can now carry 15% more equipment. Extendable primary beam Î ÎAdapts the formwork to any cell size Secondary corner beam Î ÎModular orientation as close as possible to the concrete skin Eco+ panel Î ÎFull surface and optimum stability with four supports per end TopDalle Eco Formwork - April

4 Slab formwork that combines safety with ecology Productivity 30 m 2 / person / day at a height of 2.50 m (formwork, adjustment, cladding, and formwork removal). Easy removal The drop-head for fast removal integrated in the technical support (Alphi patented system) keeps the slab supported during formwork removal. The rotation of the aluminium structure takes less time. Surface continuity Working on a solid surface facilitates mobility above the formwork. The continual adjustment of the extendable primary beam and the secondary corner beam allows working close to the edges of the cell Compliant with the Decree dated September 2004 concerning falls from height and standards NF E and NF X Practical use Simplified assembly due to adjacent Eco+ panels. The range needs fewer products due to the extendable primary beam. At the end of the span, the spacing of the Eco+ panel can be adjusted to the cell, leaving a 10 cm gap. Easier identification Coloured tips allow easy recognition of different Eco+ panel lengths. 4

5 Ergonomics 20% less weight The portable elements of TopDalle Eco are 20% lighter than traditional solutions. Making work less arduous The system limits manual load handling Less noise pollution Eco+ panels have shock-absorbent plastic tips, which reduce noise. Concrete formwork thickness Above 80 cm, according to configuration. Economy Strength and durability Exclusive extrusion process to create wide, monobloc sections. The plastic tips are shock-absorbent, limiting breakage. Compatibility Topdalle Eco is compatible with earlier Alphi product lines. Maintenance Servicing is simplified because aluminium is easy to repair. Quality Higher quality of concrete soffits Deflection limited to L/400 (quality exceeding the DTU 21 recommendation for concrete floors). Nailing on timber insert Plywood (15 mm authorised) secured using nails. The asymmetric insert can be adapted to various configurations. Regulations Beams are designed in accordance with standard NF concerning formwork. Cleanliness The shape of the Eco+ panel limits laitance on the vertical wall. All TopDalle Eco elements have been tested by the LOCIE laboratory at the University of Savoie. Safety and ergonomic performance TopDalle Eco is the best-performing framework of its generation in terms of the requirements of standards NF E and NF X Fall from ground level NF E Fall from height NF E Physical positions causing strain Falling objects NF E Mediocre Manual load handling NF X Excellent TopDalle Eco Formwork - April

9 Operating procedure WARNING: Insert the primary beams in the large bushings of the technical support 1 - Starting from a corner of the room, set up a primary beam on two technical supports (TS) stabilised by tripods. - Mount a second primary beam on two TSs stabilised by tripods. - Use of lightweight mobile safety ladder in accordance with regulations. ÎÎRefer to the layout drawing. 2 - Setting up Eco+ panels using the Top Perche. ÎÎObserve the layout plan. TopDalle Eco Formwork - April

10 Operating procedure 3 Starting to set up an Eco+ panel: - The installer lifts the panel between the two primary beams and then lowers the Top Perche, ensuring that the ends of the panel are properly engaged in the primaries. 4 - Setting up Eco+ panels from one to the next using the Top Perche. - Position the adjacent panels. 10

11 5 - Mounting a primary beam on a TS stabilised by a tripod. 6 - The installer uses the prop to position the primary beam. TopDalle Eco Formwork - April

12 Operating procedure 7 - Continue setting up the Eco+ panels as described in Step Finish installing the Eco+ panels. 12

13 Installing the extendable beam - Unlock the beam by loosening the wing nut. - Adjust the beam to the desired length. - Lock the beam by tightening the wing nut. TopDalle Eco Formwork - April

14 Operating procedure 5 Note: The extendable primary beam must be adjusted and locked before assembly. - After the length has been adjusted and locked, the extendable primary beam is positioned on stabilised props. 6 - The installer uses the prop to position the second extendable primary beam. 14

15 Installing the secondary corner beam - Unlock the beam by loosening the wing nut. - Adjust the beam to the desired length. - Lock the beam by tightening the wing nut. TopDalle Eco Formwork - April

16 Operating procedure 7 Note: The secondary corner beam must be adjusted and locked before assembly. - Position the secondary corner beam. 8 - The articulated heads of the secondary corner beam allow it to be adjusted to any configuration. 16

17 9 - Continue installing the Eco+ panels Continuer fitting the Eco+ panels using the Top Perche, from one to the next. TopDalle Eco Formwork - April

18 Operating procedure 11 - Repeat Steps 9 and 10, and finish installing the TopDalle Eco using secondary corner beams where necessary. 12 Make a final check to ensure the heads are locked at this stage. - Fine-tune the level using a laser level, TS by TS. - A gauge stick hanging from the formwork allows laser adjustment to be performed by one person. 18

19 13 - When the structure is finished and the height has been adjusted: laying the plywood. - Use of plywood cutting support to cut plywood. ÎÎPeripheral safety (web, beam) completed previously. ÎÎUse of plywood cutting support to cut plywood. No walking on the plywood panels, except for personnel trained and qualified to install plywood panels Nailing. - Ensure that a load-bearing member is present under the plywood sheet joins. - Check the sealing of the formwork between plywood sheets and at the edges.
