SN024 - Rail Mounting Bolt for Steel Substructure

Fastening to roof substructures made of wood or steel is possible. This fastening is possible for pitched roofs with a tilt angle of max. 20°. The positioning of the hanger bolts must be determined according to the structural requirements of the location and the installation situation. In doing so, it must again be checked whether the measurements taken as a basis in the planning match the actual measurements found on the roof (if necessary, adjustments must be made). At the marked positions, the roofing is to be pierced in the area of the raised corrugation/ridge and subject to the existing roof structure the hanger bolts are to be fixed on the rafter/purlins in accordance with the regulations (Eurocode 5, information in the approvals from the building authority). In doing so, it must be ensured that the seals and/or storm washers are pressed to the roof membrane to create a form-fit connection. It must be ensured that only hanger bolts or solar fasteners are used that are capable of safely transmitting the occurring forces to the roofing construction and of guaranteeing the impermeability of the roofing. The load bearing capacity of the hanger bolts must be proven.
