Method and device for producing roof cladding and thermal insulation

The invention relates to a method and an apparatus for the production of a roof cladding and thermal insulation for a roof rack parts for storing a roof covering having building. The invention relates in particular to such measures that a roof lining or a roof lining and thermal insulation mainly in an industrial building, whereby

provided for the storage of a roof covering, in particular a metallic covering or a supporting metal, roof rack parts are.

It is usually common practice to apply thermal insulation, if required, to the tops of roof rack members and then to apply the roof covering or the support metal on this insulation. Is a high U-value (i.e. a low heat transfer) is required, then the thickness of the insulation can be increased. It results here however, difficulties in attaching thick insulation, as there is a tendency for holes or leaks around the fastening bolts for the roof covering results, since the distance between the roof covering and the roof rack parts is a slight Movement of the bolts allowed. Furthermore, there is a tendency for the insulation where it over the roof rack parts is to be pressed together, so that there is a reduced U-value and thus an increased heat transfer results.

It is possible to have a lining underneath the roof rack elements to attach, then working from below, but this requires a section or step-by-step Proceeding and relocating the systems, in addition, it is difficult to apply insulation material over the cladding .

The invention is therefore based on the object to remedy this and, mainly in an industrial building that Attaching a roof cladding and insulation to enable

that are not impaired in their cohesion, has good insulation properties and wherein the construction of such a roof can be done in a simple manner.

To solve this problem, the invention is based on the one-r The aforementioned method and according to the invention consists in that at a point below the height of the roof rack upper parts the lining is fitted, working from above and then the roof covering above the Roof rack parts is attached, the cladding either itself sufficiently thermally insulated or above the roof cladding thermal insulation is housed.

According to a first aspect, the present invention provides therefore a method for creating roof cladding and thermal insulation in a building is available, which has roof rack parts for storage and for attaching a roof covering. This is the roof lining fitted in their position below the level of the tops of the roof rack elements. It is particularly advantageous that in this case, work can be carried out from above, above the roof cladding is then, also working from above, the roof covering attached to the roof rack parts. Usually the headlining itself is sufficiently thermally insulating; If this is not the case, then a thermal insulation can be attached over the roof cladding can for example consist of fiberglass fabric.

The building itself usually has main girders and roof girder parts supported by these main girders - in a conventional roof structure, these elements are hereinafter referred to as rafters or roof rungs (with regard to the main girder) and referred to as the purlin or the roof girder parts. The headliner preferably extends immediately below the roof rack parts. This makes it possible for the roof lining not to be too far removed from the roof level itself, so that it can be fitted and attached is easy. For example, as is preferred, the roof rack parts are at a slight distance from the Main beams held, with the attachment between the two for example with the help of support blocks or needles or cleats can be made, then the cladding preferably extends above the main beam; this avoids that the cladding must be cut because of the main beams; However, some editing is because of the further above mentioned cleats required.

The cladding is preferably in the form of panels and can be designed in such a way that it carries suitable thermal insulation, for example glass fiber mats. The one below the more commonly used term "cladding" is generally only used for a covering surface, although this covering surface or top surface may be thick enough to be essentially thermal in itself Isolation to be considered. In places below skylights or translucent areas, translucent or transparent panels can also be used as cladding,

6098 13/0297

so that the shape of a double glazing results.

The invention effectively avoids the disadvantages which arise when the insulation is applied to the upper area the roof rack parts must be placed, one of these disadvantages is that where fasteners have to run through the porous material on the roof rack parts, leaks and leaks are formed. the The invention also improves the fire resistance of the roof rack elements, the acoustics of the building and provides good ventilation for the area below the roof covering.

The method according to the invention preferably comprises the assembly of the carrier elements for the roof cladding on the roof carrier parts without screwing, riveting or bolting, i.e. without the need to significantly dig into the material of the Roof rack parts are penetrated; this also avoids drilling or punching holes in the roof rack parts, which is time consuming. This avoids difficult screwing and riveting processes at roof height. The storage elements for the headliners are locked together so no shifting due to normal, upward or downward facing Force effects, for example by winds, can take place. A preferred embodiment results when Roof rack members are used that have floor flanges and upturned lips, as is the case with Z-shaped roof purlins with such lips (roof rack parts) is; the bearing elements for the cladding then have areas that are bent at the top and that extend over the areas that are directed upwards Lips or web-shaped approaches on the roof rack

parts are pushed. This results in a loose but stable engagement, which makes it possible for the Support elements for the roof cladding can only be dropped down into their end position. Alternatively but it is also possible to use the U-shaped bent parts, for example with the help of pliers Squeeze them together so that they are over the lips of the roof rack parts are pressed or clamped. Spring clips or other retaining elements can also be used to secure a to establish an even clearer and form-fitting connection.

If the roof rack part only has a floor flange, however, if it does not have an upwardly directed lip, then the support element for the cladding can have laterally projecting parts have with which it rests on the flange; if desired, spring clips can also be provided, especially during assembly, prevent the support elements for the cladding from sliding off.

However, if drilling or punching the roof rack elements is permitted, especially when it comes to inexpensive stocks of pre-cut roof rack parts, then the Safety clearamers can also be introduced into an opening, for example in the bottom flange of the bearing element. Alternatively you can the openings or bores are also located in a substantially vertical surface of the roof rack parts, wherein the support elements for the cladding then have an essentially vertical flange or some other part, which is attached to the roof rack part, for example

by pushing in or snapping in plastic Thorns or wedges.

The carrier element for the cladding is preferably a T-bar that extends parallel to the roof carrier parts extends; the T-bar can be kept narrow and light in cross-section, since it derives its strength from the roof rack part derives itself.

Is the cladding designed to be self-supporting, for example if it is in the form of a self-supporting panel, then the cladding can move from the support element to Carrier element, i.e. in the exemplary embodiment extend approximately from T-bar to T-bar, without the need for further bearing elements The panels, if panels are used, have abutting edges that are at right angles extend to the support elements. However, such an arrangement is not necessarily preferred, because it is more advantageous So-called auxiliary bearing elements are provided for the cladding, which are also T-bars can; these auxiliary bearing elements extend at right angles to the bearing elements that support the cladding. The auxiliary bearing elements for the cladding can have corresponding edge edges of the panels when panels are in use. The auxiliary bearing elements are also preferred without screwing, Bolting or riveting fitted and arranged.

In a preferred embodiment, one end of the auxiliary bearing element is inserted into an opening in the bearing element, which runs at right angles to this, inserted (in the case of the storage

element is preferably the one further ahead mentioned bearing element for the cladding). The other end of the auxiliary bearing element lies on a substantially horizontal one Surface of a further bearing element (this is preferably the next adjacent, further Bearing element for the cladding, also already mentioned above) The arrangement is preferably such that the inserted The end of the auxiliary bearing element extends between the next two bearing elements, preferably through one laterally directional movement of the end part; for this purpose, one end of the auxiliary bearing element can have a recess (for example a groove or a cutout), this recess preferably extends starting from its lower edge up. The other end of the auxiliary bearing element then has a lateral projection that connects to the recess the next auxiliary bearing element comes into engagement. The lateral projection can only be one act bent tongue or an extension, which is located at the end of the auxiliary bearing element.

In an alternative embodiment of the auxiliary bearing element, a generally vertically extending middle rib or a web and lower, generally horizontally projecting flanges on either side of the web are provided. At either end this auxiliary bearing element is a part of the flange cut away shortly before the end area, so that a recess or cutouts are formed which have a narrow flange region immediately adjacent to the end of this auxiliary bearing element leave. The arrangement is designed so that the narrow flange area of one of these auxiliary bearing elements in

609613/0297

the recess or in a section of the next auxiliary bearing element engages, the narrow flange area of this next auxiliary bearing element, which is also in operative connection stands with the recess or the cutout of the first auxiliary bearing element. As the narrow or small Flange areas at one end of the auxiliary bearing element are pushed through the opening in the other bearing element must and there a locking in the longitudinal direction of the auxiliary bearing elements is required, the narrow flange areas at one end of the auxiliary bearing elements preferably have a greater lateral extension than that at the other end of the auxiliary bearing element. With such an arrangement these first narrow flange areas are not pushed through the opening in the bearing elements, while this is the case with the second narrow flange is the case.

Other configurations and alternatives are also possible. For example, the auxiliary bearing element can be quite generally via a recess in the form of a connecting element at one end (female joint member) and via a mandrel or Have a pin for a male joint member on the other end. In particular if it is the auxiliary bearing element if the fairing is the hollow section of an open T-link, the spike-like connector becomes (male joint member) inserted into the opening in the bearing element and then connects to the recess of the aligned, preceding auxiliary bearing element.
