Load Transfer Doweling Systems - Speed Plate

Plate Dowel System

Speed Plate is a patented sleeve and steel plate dowel system. Speed Plate® 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 ensures consistent bearing stresses on the concrete at the joint face and fully embedded depth of the dowel. Speed Plate system is comprised of a high density plastic sleeve pocket former and insert to properly position the load plate dowel for axial and lateral shrinkage capability. Steel load plate dowel is manufactured from hot rolled steel plate meeting ASTM A36.

Sika Greenstreak’s Speed Plate® reduces the number of dowels required when compared with conventional doweling systems. Speed Plate® will allow the installer to increase the spacing between dowels, further reducing labor and material costs. The spacing chart above is conservative and is based on spacing recommendations in accordance with ACI 360R-10. Advantages:

• Larger steel plates provide greater overall surface area to reduce bearing stresses on concrete
• Non-tapered plate profile ensures consistent bearing stresses at joint face and full depth of dowel
• Engineered to provide optimal use of steel
• Integral, patented sleeve insert eliminates lateral restraint between concrete sections
• A doweling method in accordance with:

ACI 302 Guide for Concrete Floor and Slab Construction ACI 330 Guide for the Design and Construction of Concrete Parking Lots ACI 360 Design of Slabs-on-Ground

• One-piece design with alignment marks and preinstalled nails makes installation quick and easy
• Ensures proper dowel alignment at a construction joint
• Reduces labor
• No form drilling required
• No greasing, spinning, removing, or replacing of dowels

Usage

Concrete slabs-on-ground requiring effective load transfer across joints. Typical structures include:

• Warehouse / Distribution Centers
• Big Box Stores
• Manufacturing Facilities
• Commercial / Industrial Complexes
• Entertainment Centers
• Recreational Complexes
• Parking Lots and Site Paving
• Airports

Application

Application Steps

APPLICATION INSTRUCTIONS

1. Snap a chalk line or use the Speed Plate® alignment tool along the form to the desired dowel depth. Ideally, the centerline of the Speed Plate® sleeve is positioned at the centerline of the slab, but is not less than 2 ¼” from the top of the slab.

2. Set forms and nail the Speed Plate® sleeve to the form with the preset nails provided. Speed Plate® thickness and spacing shall be per contract documents. Pour and finish the first slab according to ACI specifications. IMPORTANT: Use internal vibration to consolidate the concrete around the Speed Plate® system.

3. Strip forms and bend nails flush with the face of the construction joint.

4. Insert the steel Speed Plate® dowel through the label and into the sleeve cavity. If possible, this should be done while the concrete is still green for easier placement. Do not use excessive force while inserting Speed Plate® dowel as this could potentially damage the concrete.

5. Pour and finish the adjacent slab(s), again use an internal vibrator to consolidate the concrete around the Speed Plate® dowels according to ACI specifications.
