Shear dowel HEDGeneralSingle shear dowel HED – Expansion joint dowelling for concrete structural elementsThe productDue to the use of these HED Typeshear dowels, dowelling applicationson expansion joints can be solvedsimply and reliably even where thereare varying shear forces.It guarantees a displacement of thestructural element in the longitudinalaxis of the rod up to a joint width of50 mm.All types are available with a specialfire protection sleeve for classificationaccording to F90.FeaturesPrevents component displacementin the area of the jointSimple, precise-fit assembly usingshear dowel sleeves on the shuttering.A rip-proof film protects thesleeve from ingress of concreteThere is no requirement to drillthrough the shuttering or supplementarydrilling of the concrete.Application areaSingle Type HED shear dowels areused wherever shear forces are to betransferred through structural joints,e.g. expansion joints between concreteslabs, in floors and walls, forjoints between supports and walls orbetween balconies and floors.50www.h-bau.com

Shear dowel HEDFire protectionFire protection sleevesIf there are technical fire protectionrequirements on the construction elementsaccording to DIN 4102 Part 2,the shear dowels must be installedwith fire protection sleeves.In order to meet the classification F90the unprotected dowel must be fittedwith a fire protection sleeve in thejoint.In the event of a fire, the fire protectionsleeve foams and completely fillsthe joint.The sleeves are supplied in the followingstrengths:20 for joint width 20-30 mm40 for joint width 40 - 50 mmThe fire protection sleeves can becombined for larger joint widths.Dimensions of the fire protection sleevesFire protection sleeve for HED-S + GS/GK & HED-P110 x 110 mm (b x h)hole diameter Ø 20 mm - Ø 30 mmstrength 20 mm und 40 mmFire protection sleeve for HED-S + GSQ160 x 110 mm (b x h)hole diameter Ø 20 mm - Ø 30 mmstrength 20 mm und 40 mm54www.h-bau.com
