Engineered connection specialist, Leviat, has extended its market-leading Isedio range of industrial leave-in-place formwork joint systems with the launch of ProWaveJoint, an armoured edged protection and load transfer jointing system, specially designed to provide impact-free and smooth transition across concrete floor joints in high traffic industrial factories and warehouses.
Conforming fully with The Concrete Society’s TR34 4th edition, guide to design and construction of warehouse floors, the new Isedio ProWaveJoint reflects the growing customer preference for impact-free transition, featuring two wave-shaped top strips, precision machined to create sharp edges and a flat top surface, to ensure smooth, impact free transition of hard nylon wheeled abrasive materials handling equipment.
Supporting the steel top strips, which are anchored by shear studs to the concrete arrises on each side of the joint, are upper and lower divider plates, connected by a special fastener that allows simple adjustment to suit different slab depths. Special asymmetric plate dowels and sleeves transfer the load across the two adjacent slab sections, whilst allowing for up to 20mm lateral movement in each direction to accommodate contraction of the slabs. An adjustable intersection post is available for different slab depths, to create corners and 3-way and 4-way connections.
The joint is designed such that, once cast in situ, the two slab panels on either side begin to cure and shrink, at which point the joint separates, with one slab panel housing the sleeve and top strip and the other, the top strip divider plate and dowel. The dowel, embedded in both slab panels, bridges across the joint, providing load transfer, whilst the special wave pattern allows for 25mm joint opening, maintaining impact-free wheel transition across the joint.
Virtually maintenance-free, the new Isedio ProWaveJoint provides a high level of support to the concrete arrises, reducing impact areas and cracking which can lead to health and safety issues, damage to materials handling equipment, as well as disruption to normal operation, and even closure of key warehouse areas.
Further information on design capacities, material specifications and tolerances are included in the Isedio ProWaveJoint Product Data Sheet and Load Transfer Information Sheet, both of which are available to download from Isedio.com/resources.
