Definitions

  • the invention relates to a roof, in particular industrial roof, with a covering made of corrugated sheets, preferably trapezoidal sheets, which are covered on the outside with a thermal insulation layer and a skin made of bituminous sheets.
  • Such roofs are suitable for covering larger halls, e.g. Machine halls, warehouses or office buildings.
  • the trapezoidal sheets ensure the necessary strength due to the strength achieved by the beads, even with thinner material.
  • the thermal insulation layer is protected by its covering through the roof skin, which advantageously consists of bituminous roofing membranes.
  • the trapezoidal sheets can e.g. connected with rivets and thus secured.
  • a thermal insulation layer in the form of is usually first placed on the trapezoidal sheets individual sheets or prefabricated parts, for example made of polystyrene, applied. Then the skin is put on, which is composed of individual, eg bituminous, plastic sealing sheets; Finally, the whole thing is weighed down with a pile of gravel, so that the skin cannot stand out.
  • a prerequisite for such a structure is, however, that the roof has only a very slight or no slope. In the case of larger areas, additional iron or reinforced concrete beams must be used for stabilization.
  • the thermal insulation material and the sealing membrane do not lie on the entire surface, which is why such roofs are not considered to be storm-proof. The movement of the corrugated sheets can cause defects in the roof skin.
  • the poor fastening options for the thermal insulation elements and the roofing membranes also mean that the trapezoidal sheets can easily damage the insulation layer and the skin.
  • the invention seeks to remedy this.
  • the invention as characterized in the claims, solves the problem of designing a roof of the type described in such a way that it can be designed for prescribed wind suction loads with a simple construction made of flame-retardant or non-flammable materials.
  • the advantage that can be achieved by the invention is that, through the filling of the beads of the trapezoidal sheets and the arrangement of the thermal insulation layer and the skin on the filling, the point connection with the filling and / or the trapezoidal sheets, a full-surface support for the thermal insulation layer and the roof skin is obtained and the mere absorption of considerably larger wind suction loads is thereby achieved; in addition, a composite effect of the load-bearing filling material with the metal sheets is achieved, the webs of trapezoidal sheets against damage, for example from bulges backs up. Since such mechanical types can be used as point connections, they in turn prevent damage to the roof.
  • the fillings can be parts of a continuous support and advantageously consist of lightweight cellar concrete with a bulk density of approx. 1,000 kp / m 3.
  • the non-combustible lightweight cellar concrete also has a heat-insulating effect, so that, if necessary, the cell lightweight - The layer of heat insulation material to be applied can be reduced accordingly.
  • the costs caused by the lightweight cellular concrete can be at least partially offset by this.
  • Cell lightweight concrete is self-sufficient to the extent that, despite the additional stress caused by the trapezoidal sheets, further substructures are generally not required.
  • the load-bearing capacity can be increased by reinforcement made of cellular lightweight concrete, which also considerably reduces the vibrations that otherwise occur in such roofs.
  • Trapezoidal sheet metal ribs which are perforated in the webs and mounted diagonally - as reinforcement on the trapezoidal sheets, are often less complex, but statistically sufficient.
  • other hollow profiles arranged crosswise or diagonally which can also be arranged in reverse, are also possible. When laid crosswise, a grid is created in the concrete so that the sheets can be subjected to considerably higher loads.
  • the ribs are light, so that the advantage achieved with the composite effect is not canceled out by an additional weight load.
  • Trapezoidal sheet metal ribs can be 40 mm high, for example.
  • the ribs can be installed at 45 °.
  • the connection of the Wär medämmimplantation and the roof skin can be easily achieved by gas concrete nails and washers.
  • the beads can be filled more easily with lightweight cellular concrete if they point upwards in the diagonally arranged sheet metal ribs. Ribs laid diagonally over trapezoidal sheets with inward-facing beads can also be easily filled.
  • the layer can be 40 mm thick when using lightweight cellular concrete; it then also forms a sufficient abutment for receiving the gas concrete nails or dowels with which the thermal insulation layer and the roof skin are mechanically connected.
  • the sheets show little deflection because they have better stability due to the composite effect of the diagonally laid sheets. Bumps or other damage to the sheet metal are practically impossible with supports made of lightweight cellular concrete. You can also create sloping roofs according to this principle, whereby the support, especially if it consists of lightweight cellular concrete, can also be used for thermal insulation and for fastening additional sealing agents. A particular advantage of such a roof is that it is considered storm-proof.
  • the beads 3 projecting inward are provided with a filling 2 consisting of lightweight cellular concrete.
  • the top of the concrete also serves as a full-surface support for the thermal insulation elements 5 to be laid on the sheets.
  • a roof skin made of plastic sealing sheets 6 is applied to the thermal insulation elements 5 laid; first, the thermal insulation elements 5 and the plastic sealing membrane 6 are loosely laid. Only then are both mechanically connected to the trapezoidal sheets 1 using commercially available holders 16 and screws 9. Leaks at the connection point are avoided by the following sealing film 15, which is welded to the plastic sealing membrane 6.
  • the gravel also acts as a reflective layer.
  • Fig. 1 in this embodiment, only the inwardly facing beads 3 to their upper edge, ie filled up to the height of the beads 4 pointing outwards.
  • the outward-facing bead 4 and the surface of the lightweight cellular concrete 2 then form a continuous surface onto which the thermal insulation elements 5 are applied simply and lying flat and fastened with holders 16 and screws 9 and washers 8. This avoids cavities.
  • FIG. 2 shows a roof reinforced by reinforcement with a continuous support connecting the fillings 2.
  • a trapezoidal sheet 10 laid with the bead 11 upwards serves as reinforcement.
  • This trapezoidal sheet 10 has bores 14 in the webs 12, so that the foam concrete can flow well into the free spaces.
  • FIG. 3 makes it clear how the trapezoidal sheets 10 are laid diagonally over the trapezoidal sheets 1, so that a net which substantially strengthens the overall construction is created.
  • the e.g. 40 mm high trapezoidal sheet metal ribs 10 which have 12 holes 14 in the webs, mounted at 45 ° on the trapezoidal sheet metal 1, after which the entire construction is then filled with lightweight cellular concrete 2, with a bulk density of approx. 1,000 kp / m ' .
  • thermal insulation elements 5 or only the plastic sealing sheets 6 are loosely placed and mechanically fastened in the concrete with dowels or gas concrete nails 7, barbs 17 and washers 8. *
  • FIG. 4 shows a so-called inverted roof, the plastic sealing membrane 6 being placed directly on the lightweight cellular concrete 2 and the beads 4.
