Easy removal The drop-head for fast removal integrated in the technical support (Alphi patented system) keeps the slab supported during formwork removal. Easier identification The beams are colour-coded, in compliance with the layout drawings drafted by the Alphi design office. Hand-portable The simple components in the Dalphi system make it possible to work independently, with no need for a crane. This leaves the crane available for other tasks. LIGHTWEIGHT AND HAND-PORTABLE EQUIPMENT The integrated drop-head for fast removal enables a quicker turnaround of the aluminium structure The drop-head integrated in the prop allows for fast formwork removal without releasing pressure on the slab 4

11 FORMWORK ALPHISAFE COLLECTIVE PROTECTION AlphiSafe is a collective protection system for formwork and slab edges. The technical innovations in the system allow safe installation and automatic locking. A robust system, AlphiSafe is certified by Ginger CEBTP, as per the EN standard of July 2013, with certain components classed A and B. AlphiSafe is distinguished by its height of 1.30 m which is above the minimum height of 1.00 m set by the standard, and protects traditional slab formwork up to 30 cm thick. The grid is locked at the top by the anti-lifting pin and locked in rotation at the base.

There might have been some changes since then. - The use of our systems in conjunction with those other manufacturers is not without risk and requires specific monitoring. - Before starting to set up, remember to secure the area. Click here or scan the QR code to access the instruction video. PREPARATORY STAGE distributes Do not place the props against the wall Caution: it is essential to lock the head 12 NB: even if they are not always visible in the image, Dalphi is mounted by 2 form fitters. Reception of equipment on the worksite: check quantities and validate delivery note. Precise distribution of the equipment according to the first phases of formwork defined by the layout drawing. Prop height adjustment and cased positioning of formwork heads: lock with hammer.

13 FORMWORK PROCEDURE: FORMWORK 1 prop + tripod 2 - Starting from a corner of the room, set up a primary beam on 2 technical supports (ST) stabilised by tripods. - Start mounting a secondary beam on a third ST. - Store the plywood panels on the deck or in wheeled racks. - Use a lightweight rolling safety ladder in compliance with regulations. Caution: engage the primary beams on the large bushings of the technical support. - Set up a second primary beam on another ST. ÎÎ Refer to calculation chart. 3 4 Gap = 39 cm - Finish setting up the secondary beams. - Do not leave gaps greater than 39 cm. - Use a template to observe 39 cm spacing. ÎÎ Observe the layout drawing. - Set up another primary beam on ST. 13

14 Dalphi PROCEDURE: FORMWORK Fit the secondary beams as you move along. - Finish setting up the secondary beams Set up another secondary beam on ST. - Set up another primary beam on ST. 14

15 FORMWORK Fit the secondary beams as you move along. - Set up another primary beam on ST Fit the secondary beams as you move along, observing a 39 cm gap. - Finish setting up the secondary beams. 15

16 Dalphi PROCEDURE: FORMWORK, FINISHING & CASTING Adjust the level using a laser level, ST by ST. - A gauge stick hanging from the formwork allows laser adjustment to be performed by one person. Perform a final head locking check at this stage. - When the structure is finished and the height has been adjusted: lay the plywood. - Use of plywood cutting support (see Accessories p. 10). ÎÎ Peripheral safety (skin, girder, etc.) ensured beforehand distributes - Nailing using 40 mm (max.) nails. - Ensure that a load-bearing member is present under the plywood sheet join. - Check the sealing of the formwork between plywood sheets and at the edges. Walking on plywood panels is restricted to personnel trained and authorised to lay plywood panels. - Lay the concrete slag. Î Î Spread the concrete on the formwork without overloading the beams and the technical supports. 16

17 FORMWORK PROCEDURE: FORMWORK REMOVAL distributes - Slab formwork removal: strike down the formwork heads from the STs as you progress. - The primary beams and the secondary beams drop by 17 cm. - The STs remain in position. - Slab formwork removal: remove, as you progress, the secondary beams and finally the primary beams. - Store them in the wheeled racks distributes - Slab formwork removal: remove the ST positioned at the cell edges. - Leave the other STs in place for at least 3 days (according to the concrete type and external temperature). - Lower the panel elevator to mid-height. - Remove the plywood sheet. 17

Dalphi PROCEDURE: FORMWORK REMOVAL 21 22 - Position

- Remove the plywood panel using a panel elevator.

18 Dalphi PROCEDURE: FORMWORK REMOVAL Position the panel elevator and remove the corresponding ST. - Remove the plywood panel using a panel elevator. - Install the first drying prop, allowing one prop per 5 m 2 (general case) Repeat steps 21 and Repeat the operations from step 1 on a higher level. 18

19 FORMWORK SPECIAL CASES USE WITH NON-TILT FORK 20 cm Restricted space - Use of fork (assembly without using fast formwork removal). Fork Bracket Front face overhang management - Use in cantilever configuration with fork and bracket. - The fork can be used to position the STs under the primaries and not at the ends, offering additional adjustment. ⅓ of beam max Fork Girder formwork - Drop less than 35 cm.
