Dowel Range
Dominator Dowel The Dominator 75/10 Dowel is the most advanced in plate dowel design, and has the following features:
The width and thickness of the Dominator Dowel have been selected for:
A tapered dowel plate is not used, since a tapered plate would rapidly reduce the dowel capacity as the joint width increases.
Hi-move dowels - Plate dowels Using Plate Dowel technology the Hi-Move Plate Dowel system is a larger 10mm plate to cope with wider joint openings and has additional lateral (sideways) movement for stressed or SCC slabs. Hi-Move plate dowels consist of a one piece nail on plastic sleeve (nails are built in) and a 10mm thick steel plate. Galvanized or Stainless Steel Plates are also available.
Hi-move dowels - Dowel clip The dowel for shrinkage compensating concrete and pre-stressed floor slabs Internal joints are necessary in large shrinkage compensating concrete (SCC) and pre-stressed concrete floor slabs. These joints present special problems to designers. Load transfer. Load transfer across joints is important in all slab joints. It becomes even more critical in stressed slabs where thicknesses are often reduced. Joint Width. Both SCC and stressed slab construction methods result in wide joint openings. These can reach 35 mm in many stressed slab joints. In these joints, square dowels give better bending characteristics than plate dowels. Longitudinal Movement. Considerable longitudinal movement occurs at joints in both types of slabs. In SCC slabs, up to 30 mm differential movement may occur along the line of the joint. LEROY DEAN HI-MOVE DOWELS:
Hi-move dowel - Sleeve nail-on U.S's only nail on sleeve that are custom made for Post Tension & Shrinkage Compensation Slabs.
Square dowels One of the first products in our range, Leroy Dean introduced the Square Dowel into the United States last century. Leroy Dean Square Dowels are available in sizes 16, 20 and 25mm and Galvanized or Stainless Steels.
LEROY DEAN SPEED SLEEVES The nail on Sleeve System for round dowel bars. Speed Sleeves eliminate the need for penetrating formwork and ensure accurate alignment. Speed Sleeves use ridged plastic to reduce the risk of the material around the dowel bar compressing and allowing deflection. Speed Sleeves are available in 16, 20 and 25mm diameters.
ROUND DOWELS Round dowel is a dowel bar of plain round reinforcing steel to NZS3402:1 989, with burr free ends, and supplied complete with a heat shrunk plastic sleeve on the bar. Round dowels are available loose or in assembled Ladder or Basket configuration. Round dowels are available in sizes from 12 to 40mm.
FIBER DOWELS Fiber Dowels are corrosion proof dowels for exposed critical areas. They are an alternative to galvanized square or round dowels, or stainless steel Plate Dowels. Fiber Dowels are available in sizes from 10 to 25mm and can also be assembled into Ladder or Basket configuration.
SHEAR LOAD CONNECTORS Ancon Shear Load Connectors are a twin stainless steel dowel system for use in movement joints in floor slabs, suspended slabs, and for replacing double columns & beams at structural movement joints. Other applications include joints in bridge parapets, bridge abutments and diaphragms. Shear Load Connectors are available in sizes from 14 to 65mm, DSD and DSDQ’S for lateral movement. Single versions are also available which include a sound absorbing material.
DOWEL LADDERS Dowel Ladders are welded & tied assemblies that ensure accurate dowel
alignment, thus eliminating the risk of cracking due to slab lock up and
misalignment. Dowel Ladders are available in standard 3 metre lengths and can be
supplied with a range of dowel sizes and spacing to suit the thickness of the
slab.
LOAD PLATE BASKETS Unlike round dowel baskets, the Load Plate Basket is forgiving of lateral
misalignment and will not lock joints or cause restraint to the normal shrinkage
of concrete. Load Plate Baskets are available in standard 3 metre lengths, using
10 or 6mm Load Plates at spacing to suit the thickness of the slab.
LOAD PLATE LADDERS Load Plate Ladders are another complete assembly, only that they require
plastic or concrete bar chairs for support (chairs can be supplied separately).
STAINLESS STEEL DOWELS All Leroy Dean Dowels are available in grades T304 and T316 stainless steel. For more information contact: Ron Bird |
