Hanger bolts and solar fasteners in sandwich panels

Krüger, Helmut; Ummenhofer, Thomas; Ruff, Daniel


For the energetic use of sunlit roofs, photovoltaic and solar thermal elements are mounted using different fastening systems on existing roof surfaces. For the installation on trapezoidal profiles or sandwich panels, hanger bolts and solar fasteners belong to the most prevalent fastening systems. For the structural analysis of these systems, however, only insufficient design approaches are available until up to date. Especially for the application on roofs covered with sandwich panels no design criteria is available at the present. The introduction of roof parallel loads from roof shear, wind and snow into the substructure can be specified as pressing problem. Within the scope of a research project sponsored by the DIBt (German Institute for Building Technology) design criteria for hanger bolts and solar fasteners in sandwich panels with a plastic foam core were developed. When roof parallel forces are applied to the fastener the fastener is supported by the sandwich panelsŽ surface sheet. For that reason the load bearing capacity of thin steel sheets with a thickness from 0.38 mm to 0.56 mm for different diameters of hanger bolts or solar fasteners is determined. ... mehr
