Wave Joint – AP International Joints

Theta Joint

Theta joints combines a narrow top plate and a distinctive triple curve design, for impact-free joint protection that’s easy to install. Its three sine wave shapes mean there are no straight edges, so materials handling equipment can flow smoothly across the joint in any direction. The extension plate means installers can easily choose the correct joint height on site and use any excess stock on the next job.

Applications

• Suitable for a wide range of applications. Particularly suitable for directional traffic situations (such as transfer and racking aisles in distribution centres) where materials handling vehicles pass over the joint at 90°.
• Suitable for use internally. If the product is to be used in places subject to water ingress, please request galvanised finish.
• Suitable for use with pallet trucks and front and lateral stacker trucks.

Benefits

• Triple wave shape prevents impact damage at the central arris and the two edges of the plate.
• Can be approached from any angle, even 90°, without causing impact. Suitable for directional traffic situations.
• Helps reduce noise and vibration impact on forklift drivers*.
• Allows flexibility in future building use.
• For slabs depths from 150mm to 200mm, an extension plate enables easy height adjustment on site (fixed height joints available to special order).
• Narrow top plate aids stability and allows an accurate joint level to be set easily.
• Continuous concrete ties, set down from the surface, ensure secure anchoring.
• Narrow top plate enables good concrete placement and compaction.
• Gentle wave shape aids trowel finishing.
• Compatible with TD plate dowels.
• Joint design resists significant ingress of debris into the joint.
• Supplied in mild steel as standard. Galvanised finish and stainless steel top plate options are available to special order.
• Supplied in 2.4m lengths.
• Possibility to use more dowels per one joint (5D, 6D) to increase max loads on floor
• Standard grade steel on top S235, dowel system S355 - Nylon screws M10 providing possibility of separation and work between floor fields
• Plastic cover made of highly resistant ABS plastic

Alphajoint Variants

We have optimised the AlphaJoint Classic 4010 design to give our customers the right combination of strength and versatility for every slab. We now supply three styles of AlphaJoint Classic 4010, depending on the slab depth. All styles provide the benefits listed above and are suitable for all the applications shown.

For slab depths up to 140mm – our standard AlphaJoint Classic 4010 divider plate is supplied, as shown in the picture at the top of this page.
For slab depths from 150mm to 200mm – we supply our AlphaJoint Classic 4010 with a universal divider plate. With pre-set positions, this can easily be set to multiple heights on site, which conveniently allows the same product to be used for different slab depths.
For slab depths from 220mm to 240mm – our standard AlphaJoint Classic 4010 divider plate is supplied, as shown in the picture at the top of this page.
For slab depths over 240mm – we supply a version of AlphaJoint 4010 with additional continuous concrete ties (see picture, right), to give extra reinforcement and rigidity for an easier installation.
