EXPOSED PILE SECTION Scribe a setting out line for the RSB hard points 140mm below the bottom level of the cap. DAWSON'S REDEB SUPPORT BRACKET POSITIONED Lower brackets into position. Torque jacking bolts to 180Nm and level. DAWSON SOFIT PANELS POSITIONED Ensure at least 2 brackets support each panel. Lower the sofit panels into postion with the front edge tight against the pile.Use timber wedges, to drive the panel forward against the sheet pile face then lift and lock guard rail. (not shown)

SOFIT BARS Lightly tap ends of steel bars till they have push up hard against the contours of the sheet piles. SHUTTERING The side shutters can be positioned straight onto the sofit bars. FINISH Typically after 36 hours the soffit panels and redebs are ready to be removed.

The only purpose-made sheet pile capping system available is faster and more cost effective than any on-site ‘lash ups’. The Redeb Bracket and Soffit Panels can be assembled and re-used by unskilled labour. Welding or cutting of piles is not necessary. It renders obsolete the use of individual plywood soffit panels cut out to match pile pans. Traditional ‘old fashioned’ methods use brackets welded against piles to carry longitudinal beams and shuttering timber. Such brackets have ultimately to be burned off, their stubs ground down and the piles paintwork made good. All this trouble is avoided...

Sheet piles are generally capped for Aesthetic purposes. The concrete cap serves to mask the inevitable irregularities in sheet pile length, penetration depth and line. They may also be used as a support for a railing or safety barrier. There are three models of Redeb bracket - the RSB500, RSB600 and RSB700. The RSB500 & RSB600 models are designed to work on both ‘Z’ type and ‘U’ type sheet pile sections. The RSB500 covering narrower pile sections than the RSB600. The RSB700 is exclusively designed to work with the Hoesch Larssen 700mm wide ‘U’ piles and Arcelor 750mm wide ‘U’ piles. With these...

The soffit shutter panel consists of rectangular rods which are retained within a framework. The rods are free to slide within set limits. With the panel secured on the Redeb Bracket the rectangular bars are pushed towards the sheet piles, starting from the deepest part of each pile. The bars will deck out the soffit area and assume the shape of the sheet piles including the distortion which occurs during driving. The panels’ structural members, which retain the decking bars, are capable of carrying normal loads when supported on Redeb Brackets at ‘one-pair’ of pile centres. No additional structural...

limitations of the redeb bracket Although the Redeb Support Bracket is suitable in the majority of pile cap situations there are certain limitations which must be taken into account before specifying the equipment for any given job. (If in doubt consult the manufacturer). SAFE WORKING LOAD The S.W.L. of the Redeb is specified in terms of a point load on the bracket at a certain location i.e. a load applied on the arms of the bracket at a distance of 310mm from the centre of the Hard Points. (see page 21 for technical specification) a. Bracket fixed on interlocks of ‘U’ type sheet piles - S.W.L....

The ‘Fixing Width’ is the distance between Hard Point tips when installed on any given sheet pile(s). Each Redeb model has a minimum achievable and maximum allowable ‘fixing width’ and this is different in both cases depending on whether 70° or 90° Hard Points are used. The maximum allowable fixing width must not be exceeded as this will lead to bracket damage and possible system collapse. THE JACKING BOLT SHOULD NEVER BE EXTENDED BY MORE THAN 77MM - MEASURE THE EXPOSED THREAD LENGTH IF IN DOUBT: Note: 1. There is a manufacturing tolerance on the above measurements of ±3mm. 2. For particularly...

installations of the redeb support bracket 1. Scribe a setting out line at the correct height on the pan of every pile. Using a centre punch, mark the Hard Point positions on this line. Allow a distance of 40mm from the Hard Point centres to the top surface of the bracket. Allow a distance of 100mm for the thickness of the soffit panel i.e. a total of 140mm. Note: a. To save time this marking out procedure need only be done on every alternative pile pan. Intermediate brackets can then be positioned later using the installed brackets for reference. b. On sheet pile sections with particularly steep...
