MonoLock-screw connection

The MonoLock-connection has been developed to ensure a strong and durable screw connection of Omnia panel; with load carrying members in aluminium and steel. The connection consists of a self-drilling screw in a clamp sleeve.

First a blind hole must be drilled into Omnia panel;. The self-drilling screw is screwed into the metal member together with the clamp. The clamping of the lower face sheet and the metal member is carrying the main load. Additionally, the flange of the sleeve clamps the upper face sheet and provides a flat surface.

Assembly instruction:

MonoLock-sleeve and drill screw: EJOT Saphir JT2-STS-6-6.3x60
Forstner-drill diameter: 18 mm
Torque: 6 - 10 Nm.
Frame: Aluminium 3 - 5 mm, Steel 2 - 4 mm

Other connections using screws or bolts

Edge closings and other non-load bearing connections can be achieved by assembling a profile to the edge with woodscrews in sideward direction (figure 2). Through bolting can be done, possibly by the use of load distribution plates to enable a higher loading capacity. The core should not be crushed (figure 3).

Fasteners: blind rivets

Fasteners, especially with a flange counter head, are very well suited for connections to Omnia panel;.

The high elongation-to-break of PP and the high strength of the glass fibres yield a high load capacity. Because of the welding process of the face sheets to the core no delamination caused by rivets will occur.

With load distribution plates an even higher load can be introduced (figure 4). Rivets do not only offer high load capacity, but can also be processed easily. The table below shows various types of rivets. Use this table to chose the best rivet for your application.
