MultiJoint and Individual Plate Dowels Ancon MultiJoint FLOOR CONTRACTION JOINTS The function of a free contraction joint is to allow concrete shrinkage to take place. Although the majority of movement as the concrete contracts is perpendicular to the joint, some relative movement between adjacent bays will also occur along the line of the joint. It is therefore vital that dowels allow for movement in both directions to avoid unnecessary stresses to develop in the slab and ultimately cracking. Today’s concrete floor designs have fewer joints than those in the past. With greater distance...

ANCON MULTIJOINT The MultiJoint system is an all-in-one solution to load transfer, concrete contraction, armoured edge protection and formwork in ground bearing floor slabs. It is a prefabricated steel system supplied in a standard three metre unit length and is available in four heights to suit slab depths from 150mm. Units are simply lapped end-to-end on site. A unique patented top rail transfers load into the concrete at an angle, to avoid localised cracking. Joint edge protected by two 12mm square-edged profiled steel strips Reinforcing bar welded to anchors for added rigidity Plate...

MultiJoint and Individual Plate Dowels ANCON INDIVIDUAL PLATE DOWELS Ancon individual plate dowels are a costeffective means of transferring shear loads and accommodating movement in load bearing ground floors. They are typically installed at 600mm horizontal centres and are ideal when arris protection is not required. The innovative tapered sleeves allow greater longitudinal dowel movement as the concrete contracts and joint width increases. The Ancon ADD 75/10 is suitable for the majority of applications, however where a greater capacity is required or wider than average joint widths are...

Use Ancon AHM 100/10 at 600mm horizontal centres. BUILDING PRODUCTS

MultiJoint and Individual Plate Dowels Pour Block MultiJoint X-Junction Adjustable Foot INSTALLATION GUIDANCE MultiJoint Joint layout and height is specified on slab drawings. These details should be accurately marked-out in string initially, to provide a clear visual guide. Installation of the MultiJoint system should begin either at an intersection or at a column/wall. Irrespective of type or size, all MultiJoint units are connected end-to-end in the same way. The top steel strips are overlapped and a mechanical fixing, supplied with the system, is located through the slots. Adjustable...

Individual Plate Dowels Built-in ring shanked nails on Ancon sleeves make installation a quick and easy process. 1. Fix the sleeve to the formwork using the nails provided, at the required depth and spacing (normally on the centre line of the slab, typically at 450-600mm horizontal centres). Do not remove the protective strip on the nailplate as this protects the sleeve from concrete ingress. 1 2. Fix fabric reinforcement if required. Pour concrete, ensuring good coverage around the sleeve component. 2 3. When concrete reaches sufficient strength, strike the formwork. New sub-base can be...
