Description

Die Erfindung betrifft ein Dach, insbesondere Industriedach mit einer Eindeckung aus mit Sicken versehenen, vorzugsweise Trapezblechen, die außen mit einer Wärmedämmschicht sowie einer Haut aus bituminösen Bahnen abgedeckt sind.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.

Solche Dächer eignen sich zur Abdeckung größerer Hallen, wie z.B. Maschinenhallen, Lagerhallen oder auch Bürobauten. Die Trapezbleche sorgen hierbei wegen ihrer durch die Sicken erzielten Festigkeit auch bei dünnerem Material für die notwendige Festigkeit. Die Wärmedämmschicht wird durch ihre Abdeckung durch die Dachhaut geschützt, die vorteilhaft aus bituminösen Dachbahnen besteht. Die Trapezbleche können z.B. mit Nieten verbunden und damit abgesichert werden.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.

Beim Aufbau eines solchen Daches wird üblicherweise auf die Trapezbleche zunächst eine Wärmedämmschicht in Form von einzelnen Bahnen oder vorgefertigten Teilen, z.B. aus Styropor, aufgebracht. Dann wird die Haut aufgelegt, die aus einzelnen, z.B. bituminösen Kunststoff-Dichtungsbahnen zusammengesetzt wird; schließlich beschwert man das Ganze mit einer Kiesschüttung, so daß sich die Haut nicht abheben kann. Voraussetzung für einen solchen Aufbau ist allerdings, daß das Dach nur eine sehr geringe bzw. gar keine Neigung hat. Bei größeren Flächen müssen zur Stabilisierung weitere Eisen- oder Eisenbetonträger eingesetzt werden. Ferner liegen das Wärmedämm-Material und die Dichtungsbahn nicht vollflächig auf, weshalb solche Dächer nicht als sturmgesichert gelten. Die Bewegung der gesickten Bleche kann Mängel in der Dachhaut verursachen. Trotz einer relativ aufwendigen Konstruktion führen ferner die schlechten Befestigungsmöglichkeiten für die Wärmedämmelemente und die Dachbahnen dazu, daß die Trapezbleche die Dämmschicht und die Haut leicht beschädigen können.When building such a roof, 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. Furthermore, 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. Despite a relatively complex construction, 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.

Hier will die Erfindung Abhilfe schaffen. Die Erfindung, wie sie in den Ansprüchen gekennzeichnet ist, löst die Aufgabe, ein Dach der bezeichneten Art so auszubilden, daß es bei einfachem Aufbau aus schwer entflammbaren bzw. unbrennbaren Werkstoffen auf vorgeschriebene Windsoglasten ausgelegt werden kann.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.

Der durch die Erfindung erzielbare Vorteil besteht darin, daß durch die Füllung der Sicken der Trapezbleche und die Anordnung der Wärmedämmschicht sowie der Haut auf der Füllung, die punktweise Verbindung mit der Füllung und/ oder den Trapezblechen eine vollflächige Auflage für die Wärmedämmschicht und die Dachhaut gewonnen und allein dadurch schon die Aufnahme erheblich größerer Windsoglasten erreicht wird; außerdem erzielt man eine Verbundwirkung des tragfähigen Füllmaterials mit den Blechen, die bei Trapezblechen deren Stege gegen Beschädigungen, z.B. Ausbeulen sichert. Da man als punktweise Verbindungen solche mechanischer Art verwenden kann, verhindern sie ihrerseits Beschädigungen des Daches.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.

Die Füllungen können Teile einer durchgehenden Auflage sein und bestehen vorteilhaft aus Zellen-Leicht-Beton mit einer Rohdichte von ca. 1.000 kp/m3. Der nicht brennbare Zellen-Leicht-Beton wirkt zusätzlich wärmedämmend, so daß gegebenenfalls die auf den Zellen-Leicht-Beton aufzubringende Schicht aus Wärmedämmstoff entsprechend verringert werden kann. Die durch den Zellen-Leicht-Beton verursachten Kosten lassen sich hierdurch wenigstens teilweise wieder ausgleichen. Zellen-Leicht-Beton ist soweit in sich selbst tragfähig, daß trotz der zusätzlichen Belastung durch die Trapezbleche weitere Unterkonstruktionen in der Regel nicht erforderlich sind.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.

Erforderlichenfalls läßt sich die Tragfähigkeit durch eine Bewehrung aus Zellen-Leicht-Beton erhöhen, wodurch auch die sonst in derartigen Dächern auftretenden Schwingungen erheblich verringert werden.If necessary, 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.

Wenig aufwendig, aber statistisch ausreichend sind häufig Trapezblechrippen, die in den Stegen gelocht und diago- - nal als Bewehrung auf die Trapezbleche montiert sind. Außer diagonalen Trapezblechen kommen auch andere, kreuzweise oder diagonal angeordnete Hohlprofile infrage, die auch umgekehrt angeordnet werden können. Bei kreuzweiser Verlegung entsteht ein Gitter im Beton, so daß die Bleche erheblich höher belastet werden können. Die Rippen sind leicht, so daß der mit der Verbundwirkung erreichte Vorteil nicht durch eine zusätzliche Gewichtsbelastung wieder aufgehoben wird.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. In addition to diagonal trapezoidal sheets, 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.

Trapezblechrippen können z.B. 40 mm hoch sein. Die Rippen können unter 45° montiert werden. Die Verbindung der Wärmedämmelemente und der Dachhaut kann einfach durch Gasbetonnägel und Unterlegscheiben erreicht werden. Die Sicken können leichter mit Zellen-Leicht-Beton verfüllt werden, wenn sie bei den diagonal angeordneten Blechrippen nach oben weisen. Diagonal über Trapezblechen verlegte Rippen mit nach innen weisenden Sicken lassen sich ebenfalls leicht verfüllen. Die Auflage kann bei Verwendung von Zellen-Leicht-Beton 40 mm stark sein; sie bildet dann auch ein ausreichendes Widerlager für die Aufnahme der Gasbetonnägel oder von Dübeln, mit denen die Wärmedämmschicht und die Dachhaut mechanisch verbunden werden.Trapezoidal sheet metal ribs can be 40 mm high, for example. The ribs can be installed at 45 °. The connection of the Wär medämmelemente 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.

In heißeren Regionen verlegt man u.U. die Wärmedämmschicht zum Schutz der Dichtungsbahnen auf diesen. Dann folgen auf den Beton zunächst die Dachhaut, dann die Wärmedämmschicht und schließlich eine weitere Beton- bzw. eine Kiesschicht. Eine Beschädigung der z.B. aus Styropor bestehenden Wärmedämmelemente ist dadurch ausgeschlossen. Ein derartiges Dach kann auch ohne Schwierigkeiten für andere Zwecke verwendet werden, weil die gegen extreme Temperaturen empfindliche Dachhaut zusätzlich geschützt ist. Eine mechanische Befestigung der Dachhaut und der Wärmedämmelemente erübrigt sich hierbei in der Regel.In hotter regions, you may be laying the thermal insulation layer to protect the geomembranes on them. The roof skin then follows the concrete, then the thermal insulation layer and finally another layer of concrete or gravel. Damage to e.g. Thermal insulation elements made of polystyrene are excluded. Such a roof can also be used for other purposes without difficulty because the roof skin, which is sensitive to extreme temperatures, is additionally protected. Mechanical fastening of the roof skin and the thermal insulation elements is usually not necessary.

Weitere Vorteile bestehen darin, daß die Bleche eine geringe Durchbiegung zeigen, weil sie durch die Verbundwirkung der diagonal verlegten Bleche eine bessere Stabilität aufweisen. Ausbeulungen oder sonstige Beschädigungen der Bleche sind bei Auflagen aus Zellen-Leicht-Beton praktisch unmöglich. Mann kann auch geneigte Dächer nach diesem Prinzip erstellen, wobei die Auflage, insbesondere wenn sie aus Zellen-Leicht-Beton besteht, auch zur Wärmedämmung und zur Befestigung zusätzlicher Abdichtungsmittel dienen kann. Ein besonderer Vorteil eines solchen Daches ist, daß es als sturmgesichert gilt.Further advantages are that 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.

Im folgenden wird die Erfindung anhand von lediglich ein Ausführungsbeispiel darstellenden Zeichnungen näher erläutert. Es zeigt

  • Fig. 2 einen Schnitt durch ein Dach mit einer diagonal angebrachten Trapezblechrippe,
  • Fig. 3 eine Draufsicht auf ein Dach mit diagonal aufgebrachten Trapezblechrippen und
  • Fig. 4 einen Schnitt durch ein Dach mit einer unmittelbar auf den Sicken aufgebrachten Dachhaut.
In the following, the invention will be explained in more detail with reference to drawings showing only one embodiment. It shows
  • 1 shows a section through an inventive roof with filled beads,
  • 2 shows a section through a roof with a diagonally attached trapezoidal sheet metal rib,
  • Fig. 3 is a plan view of a roof with diagonally applied trapezoidal sheet metal ribs and
  • Fig. 4 shows a section through a roof with a roof skin applied directly to the beads.

Nach der Verlegung der z.B. korrosionsgeschützten Trapezbleche 1 werden die nach innen vorstehenden Sicken 3 mit einer aus Zellen-Leicht-Beton bestehenden Füllung 2 versehen. Nach dem Abbinden dient auch die Oberseite des Betons als vollflächige Auflage für die auf den Blechen zu verlegenden Wärmedämmelemente 5. Auf die verlegten Wärmedämmelemente 5 wird eine Dachhaut aus Kunststoff-Dichtungsbahnen 6 aufgebracht; zunächst sind die Wärmedämmelemente 5 und die Kunststoff-Dichtungsbahn 6 lose verlegt. Erst anschließend werden beide mit handelsüblichen Haltern 16 und Schrauben 9 mechanisch mit den Trapezblechen 1 verbunden. Undichtigkeiten vermeidet an der Verbindungsstelle die folgende Abdichtungsfolie 15, die mit der Kunststoff-Dichtungsbahn 6 verschweißt wird. Zusätzlich oder statt der mechanischen Befestigung ist es insbesondere bei Flachdächern auch möglich, zur Beschwerung anschließend eine Kiesschüttung aufzubringen. Der Kies wirkt dabei gleichzeitig als Reflexionsschicht. Wie in Fig. 1 dargestellt, werden bei dieser Ausführungsform nur die nach innen weisenden Sicken 3 bis zu ihrer Oberkante, d.h. bis zur Höhe der nach außen weisenden Sicken 4 aufgefüllt. Hierdurch bilden dann die nach außen weisende Sicke 4 und die Oberfläche des Zellen-Leicht-Betons 2 eine durchgehende Fläche, auf die die Wärmedämmelemente 5 einfach und sattaufliegend aufgebracht und mit Haltern 16 und Schrauben 9 sowie Unterlegscheiben 8 befestigt werden. Hierdurch werden Hohlräume vermieden.After laying the, for example, corrosion-protected trapezoidal sheets 1, the beads 3 projecting inward are provided with a filling 2 consisting of lightweight cellular concrete. After setting, 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. In addition to or instead of mechanical fastening, it is also possible, in particular in the case of flat roofs, to subsequently pour a gravel fill. The gravel also acts as a reflective layer. As shown in 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. As a result, 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.

Figur 2 zeigt ein durch eine Bewehrung verstärktes Dach mit einer die Füllungen 2 verbindenden durchgehenden Auflage. Als Bewehrung dient ein mit der Sicke 11 nach oben verlegtes Trapezblech 10. Dieses Trapezblech 10 weist in den Stegen 12 Bohrungen 14 auf, so daß der Schaumbeton gut in die Freiräume einfließen kann.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.

Figur 3 macht dabei deutlich, wie die Trapezbleche 10 diagonal über die Trapezbleche 1 verlegt sind, so daß ein die Gesamtkonstruktion wesentlich verstärkendes Netz entsteht. Nach dem Verlegen der Trapezbleche 1, bei denen ein Korrosionsschutz bedarfsweise vorgesehen sein kann, werden die z.B. 40 mm hohen Trapezblechrippen 10, die in den Stegen 12 Bohrungen 14 aufweisen, unter 45° auf die Trapezbleche 1 montiert, wonach dann die gesamte Konstruktion mit Zellen-Leicht-Beton 2, von einer Rohdichte von ca. 1.000 kp/m' ausgefüllt wird. Hierdurch entsteht eine Verbundwirkung von Stahl und Beton, die eine höhere Stabilität des Gesamtdaches gewährleistet. Nach der Abbindezeit des Zellen-Leicht-Betons 2, werden wie üblich Wärmedämmelemente 5 oder nur die Kunststoff-Dichtungsbahnen 6 lose aufgelegt und mit Dübeln oder Gasbetonnägeln 7, Widerhaken 17 und Unterlegscheiben 8 mechanisch in dem Beton befestigt. *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. After laying the trapezoidal sheets 1, where corrosion protection can be provided if necessary, 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 ' . This creates a composite effect of steel and concrete, which ensures greater stability of the overall roof. After the setting time of the lightweight cellular concrete 2, as usual, 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. *

Figur 4 zeigt schließlich ein sogenanntes Umkehrdach, wobei die Kunststoff-Dichtungsbahn 6 unmittelbar auf den Zellen-Leicht-Beton 2 und die Sicken 4 aufgelegt ist.Finally, 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.

Darüber liegt dann eine Schicht aus Wärmedämm-Material 5 und schließlich aus Zellen-Leicht-Beton 13, so daß eine zusätzliche Sicherung durch Gasbetonnägel oder sonstige Halter entfällt. Derartige Dächer sind für heiße Regionen mit geringen Niederschlägen gedacht.Then there is a layer of thermal insulation material 5 and finally of lightweight cellular concrete 13, so that additional securing by gas concrete nails or other holders is not necessary. Such roofs are intended for hot regions with low rainfall.
