Plate Dowel System Speed Plate is a patented sleeve and steel plate dowel system Speed Plate 174 provides load transfer across construction joints and immediately accommodates lateral and axial movement produced by concrete shrinkage and differential slab movement The large non tapered plate design reduces bearing stresses on the concrete and
All Danley dowels PD3 and Diamond Plate Dowels Round amp Square are made from Grade 300 mild steel Why use a Dowel Cradle The Dowel Cradle wire basket construction ensures the accurate placement and alignment of dowels at the correct centres and height within the slab
2013 6 13 nbsp 0183 32 The solution was to use one dowel and one diamond pin The diamond pin was rotated into the position that its two fitted sides prevented the part from rotation around the dowel With that approach you could use a 1 2 thou or less clearance on the holes and 005 or 010 on the spacing between the holes Tom Top
2008 12 31 nbsp 0183 32 Plate dowel sizes typically vary from about 4 to 6 inch diamonds or rectangles with thicknesses varying from 1 4 to 3 4 inch and are typically spaced along the joint from 18 to 30 inches on center
Criteria such as joint gap widths dowel spacing concrete property reduction and dowel and slab thickness were investigated The three main sections of this work comprising laboratory testing finite element modelling and parametric study evaluating have been combined to provide a betterinformed understanding of the performance of concrete slabs using diamond shaped
The Diamond Dowel 174 System consists of the tapered plate dowel sleeve and installation template The Diamond Dowel 174 tapered plates are available in three sizes depending on the loads wheel type and repetition The Diamond
