Purlins or rafters are attached transversely to the trusses on their upper chords. At least in wooden structures, these support elements are also referred to as rafter purlins. The following statements refer to purlins roofs, but are also applicable to rafter roof constructions.
  • Ceilings made of in-situ concrete, prefabricated concrete elements, formwork made of solid wood or wood-based materials, and trapezoidal sheets are used as the underlay for the roof structure.
  • Formworks made of wood-based materials are limited to panel sizes of 2.5 mx 2.5 m.
  • Trapezoidal sheets are limited in terms of their dimensions by the transport.
  • Metal coverings are profiled on construction sites by a coil in any length, which in principle is also possible for trapezoidal sheets of the substructure. By appropriate shaping of its blank, the resistance moments of the trapezoidal sheets can be varied within wide limits or the sheet thicknesses can be adapted to the cross-sectional shapes. Usual spans of trapezoidal sheets as multi-field beams are approx. 6 m.
  • Windwater should be removed by a short route.
  • internal drainage is often carried out via roof drains, which should each be located at low points of the areas to be drained and should have at least a distance of 50 cm from roof structures or other penetrations of the roof waterproofing. Feed channels to the roof drains should have a sufficient slope.
  • the roof drains themselves should not form thermal bridges. They must be maintained regularly and therefore be freely accessible.
  • Unused roof areas are not intended for the permanent stay of persons, the use by traffic or for the greening. They are entered only for the purpose of maintenance and general maintenance. With regard to greening, however, a distinction must be made between intensive and extensive greening, the latter corresponding, from a building physics point of view, to the formerly common gravel loads.
  • the roof structures must generally have a thermal barrier coating to meet the requirements for limiting the use of heating energy.

According to a previously used design formula, however, based on insulation boards with flat lying with respect to the two major surfaces fibers, the minimum thickness half the width between the upper goodness of the steel trapezoidal profiles were calculated.
  • Rock wool roof insulation panels including non-fibrous constituents and recycled fibers, have gross densities in the range of about 130 to about 170 kg / m 3 , which after deduction of the non-fibrous particles net bulk densities of less than 90 kg / m 3 or more than 70 kg / m 3 primary fibers including binder corresponds.
  • Large-format roof insulation panels are used with the dimensions of, for example, 2 m length x 1.2 m width.
  • the surfaces of the rock wool roof insulation panels are sensitive to the stresses of walking on and driving on handcarts, sack trucks, pallet trucks. Both the profiles of the soles of the shoes and the tires of the means of transport, such as the sharp-edged wheels of the pallet truck, lead, in addition to the pressure loads, to severe shearing stresses on the surfaces concerned. Walking or driving over the longitudinal areas above the lower chords of the trapezoidal sheeting significantly increases the harmful effects of these stresses.

These general pressures are negatively enhanced by the shearing effects of contoured soles or tires. While, for example, two-ply laid bituminous membranes still have a certain pressure-compensating effect and significantly reduce the shear stresses of the surfaces mentioned, this is not the case with the use of thin plastic and rubber sheets.
