TRANSCRIPT

TipsWith the patented, self-cleaning hexagonal threads, any radius from 1.00 m upwards can be set.

for ensuring smooth construction progress

Spray formwork on all sides with PERI Bio Clean before every use. Spray back of formwork with water immediately after concreting. This reduces the amount of cleaning work. When forming, always begin at an interuption in the course of the wall. Take account of the wall thickness as it is one of the factors deciding whether the compensation timber is to be inserted into the outside or inside panel. (see Table)

Anchoring with distribution waler for large and half-sized panelsFormwork panel thickness approx. 50 cm (Number of ties approx. 1.5 to 1.9 m wall/tie) Note: For anchoring purposes, the DW 15 wingnut pivot plate must always be used. Straight section of wall with TRIO The TRIO edge prole on the RUNDFLEX panel makes this possible.

Formwork panel thickness approx. 37 cm Used when conned working conditions do not allow a larger panel thickness with the distribution waler. (Tie proportion approx. 0.75 to 0.95 m wall/tie)

Setting the radiiAlways work in pairs in order to achieve an even and uniform curvature quickly. Radii adjustment basically begins with the spindles in the middle of the panel and then work outwards in a uniform sequence. Install the adjustable spindles with the yellow chromated parts always facing the same direction. Advantage: faster adjusting procedure due to the same turning direction. The Adjustable Spindle 210, used for adjusting the edge proles, is also operated with the 24 mm combi ratchet spanner.

Panel connectionsEnsure that the vertical centre lines of the inside and outside panels are positioned oposite each other before connecting them. Insert compensation walers up to a maximum 10 cm wide between the external and internal panels according to the tables. It may be necessary to cut compensation walers to a taper for smaller radii. Attach BFD alignment coupler and hammer in tightly.

Height extensionsRUNDFLEX panels can be extended in 60 cm increments. The panels can be extended horizontally or vertically. One extension splice 24-2 is always tted to each girder joint. Assembly is carried out on the ground: position the panels. insert splices into the lattice of the girders.

T-junctionsRUNDFLEX and TRIO can be combined to shutter T-junctions. With standard wall thicknesses, the 90 cm wide TRIO panel and two articulated or internal corners are used.

Stopend formworkWith conventional stop ends. Important: Without distribution waler on the last 2 pairs of girders due to uneven load distribution. With TRIO stopend panel and centre piece with water bar.

Stopend panel from the TRIO product range for continuous reinforcement and installation of water bars. Centre piece for wall thicknesses from 20 to 40 cm and concrete coverings of 25 or 50 mm.

Adjustable Spindle 500 is only required on the joint between panels when moving panel units. When using the I 72 panel, the adjustable spindle 210 must be used on panel joints if the radius is smallet than 2.00 m, and a wall thickness of 25 cm (see Table: Compensation Timber Widths). Note: Always insert the adjustable spindles with the yellow chromated parts facing the same direction. The same turning direction guarantees a more efcient working procedure.

tighten three-winged nuts by tapping with a hammer.

Note: When setting, always turn the spindle the same number of times. This ensures that the panels are adjusted accurately and evenly. If necessary, mark the position of the spindle with a dot of paint.

Note: Extended RUNDFLEX panels may only be erected in one piece up to a height of 7 m. For larger wall heights, extensions must be carried out .80 vertically. If transported vertically, higher units can also be moved. Pay attention to the bearing capacity of the crane splice.
