Perforated tape
A perforated tape is a perforated steel or plastic tape as a stiffening, connecting or fastening element in wood, electrical and sanitary construction. Perforated tapes exist in different thicknesses and widths and with different hole patterns. Sometimes they are called assembly lines .
Windrisp ribbon
The wind panicle tape is about 2 mm thick and 40 to 60 mm wide perforated tape that replaces the wooden wind panicle . It serves to stiffen roof structures diagonally and thus counteracts parallel displacement ( shear ) of the rafters .
The wind riser tape is usually installed on the top of the rafters. Since the windrising tape can only absorb tensile forces, at least two diagonally opposing tapes must be used per roof surface. A ridge purlin (longitudinal timber) , for example, must be installed so that wind loads are evenly directed into the windrising strip ; this directs the forces through the entire construction. The windrisp band must be stretched tight.
execution
- according to DIN 1052 (timber construction)
- Connection via lug between the rafters
- End connection more than 12 special nails 4 × 40 mm
version 1
The wind loads are concentrated at the top and bottom (concentrated nailing in these areas) in the wind panicle band. As a result, constant tensile force in the wind panicle belt.
Variant 2
The roof battens are used to transfer the wind loads into the wind riser strip. The wind riser tape is attached to each rafter with at least two nails to support the load. The load in the windrising band builds up continuously. Concentrated nailing is only necessary at the base to introduce the load.
