High capacity tie downs

Supplier:
Pryda

In the high wind zones of Australia there has always been an issue with installing trusses with the appropriate tie down products. Traditionally truss plants have designed their own tie downs and employed the services of their local engineering workshop. Often there is no design data to support these “tie downs”.

Pryda has developed a range of High Capacity Tie Down products that overcome this issue. The product range has roof tie down capacities of up to 100 kN and is supported with design data and installation instructions. The products accommodate the tie down of timber trusses to timber, steel and concrete block walls.

Products within the range include High Capacity Tie Down Kits, Cyclonic Grips, Cyclone Straps and Hold Down Brackets.

In the majority of cases the high capacity tie down products are designed and supplied as part of the total truss system by a licensed Pryda truss manufacturer.

High Capacity Tie Down Kits

The first products in the range are the High Capacity Tie-Down Kits which come complete with an 8mm galvanized plate, under washer, threaded rod, Nylock® nuts, and domed washers to accommodate the varying angles of the truss. The plate has been cleverly designed with the hole locations positioned, so that the plate can be orientated for use with single, double or triple laminated trusses. There are two kits available, one for truss tie down to timber wall frames (HCTD) the other for truss tie down to steel wall frames (HCTD/WA).

Cyclonic Grip

The next significant product in the range is the Cyclonic Grip (PCG & PCG90). The 2 models ensure it can be used in cyclonic areas for tying down roof trusses or other roof members to a steel wall frame with a “stiffened” top plate or standard 90mm top plate. It is also suitable with 90mm timber top plates. A single Cyclonic Grip can achieve uplift capacities of 15 kN.

Cyclone Strap

The Pryda Cyclone Strap range has been expanded to include a 900 mm strap manufactured from 1.2 mm thick G300-Z275 galvanized steel (QHS9/2). When doubled up a Cyclone Strap wrapped around the truss can achieve uplift capacities of 30 kN.

Hold Down Bracket

The Hold-Down Bracket (MPCPAH). It is typically used to tie down the truss to the top plate using an M12 threaded rod which has been anchored into the concrete slab. When doubled up capacities of up to 20 kN can be realized.
