Description

TECHNICAL AREA

The present invention relates to a system of prefabricated parts for creating openings of openings in roofs.

STATE OF THE ART

Conventional enclosures of openings are created individually and individually adapted to the local conditions of the roof. This enclosure is usually made of sheet metal, which has the necessary resistance to external weather conditions on the one hand, on the other hand is flexible enough to be adapted to the local roof geometry. The enclosure basically consists of four individual sheets for each side of the opening (top, bottom, left and right), which are initially created in size. Upper and lower sheets are removed by appropriate machining, e.g. adapted by rounding, bending, to the opening and the roof geometry. Subsequently, connections are made on the sheets and the sheets are connected to each other. The previous method requires on the one hand extensive technical skills and knowledge in sheet metal processing and roofing, on the other hand requires the individual creation and adjustment of the sheets a considerable amount of time. The customization also involves the risk that the adjustment is made incorrectly and the enclosure is not rainproof. Since there is no possibility of correction during sheet metal processing, in the worst case the adaptation must be carried out completely again, with the associated additional expenditure in terms of material and time.

There are so-called (chimney) templates known with which the individual sheets can be adjusted by predetermined fitting operations by bending or cutting to the individual local conditions of the roof and assembled. While these systems simplify the operations and reduce the risk of mismatching, they still require a relatively large amount of time and a high level of craftsmanship in the field of sheet metal working.

OBJECT OF THE INVENTION

The object of the invention is to provide a cost-effective and time-saving system, which allows easy and quick installation of an enclosure of a roof opening according to the local conditions and regardless of the type, height and width of the tiles used to protect against the weather.

TECHNICAL SOLUTION

The inventive system of an enclosure comprises at least one upper and / or at least one lower connection element with a width B, wherein the connection element at least one Connecting profile, wherein the connection profile has an L-shaped profile shape having a first horizontal leg and a second vertical leg, wherein the horizontal leg has one or more protrusions to form one or more gutters, the bulges substantially along the profile extend; and wherein the connection element has at least one sheet which is bent along the width B and the connection profile is suitable for connection of the other connection element.

The connection profile of the upper connection element can be connected to the connection profile of the lower connection element.

Surroundings are at all openings in roofs of buildings, such. roof skylights, fireplaces, etc., required to provide the protective, water-repellent effect of the roof surface with regard to water ingress through external weather conditions, e.g. Rain, snowfall and temperature differences, to maintain. The enclosure forms an enclosure and a vertical termination around the respective opening so that water is kept from the opening and can be routed away.

The present invention preferably uses prefabricated individual elements which can be assembled according to the specific opening and the respective local conditions.

Preferably, the connection profile of the upper connection element and the connection profile of the lower connection profile are arranged overlapping. As a result, a water-sealing transition between the connection elements is created. It should be arranged in the roof assembly respectively higher element above the other element, so as not to affect the flow of water and to prevent the accumulation of water in this area. Preferably, the upper connection element should be arranged above the lower connection element. The two-part form of the system, due to the upper and lower connection element is required for adaptation to the different inclination, since the upper connection element is arranged for the purpose of water drainage under the roof surface and the lower connection element on the roof surface. The lower connection element is intended to correspond to the length of a roof tile and compensates for the inclination, which arises that the lower region of the connection element rests on the adjacent roof surface. For this purpose, the lower (and the upper) connecting element can be provided at the factory in each case with an overall length, which in each case has the maximum length of a roof tile both in the region of the underside and in the region of the upper side of the connecting element.

The bending of the sheet metal of the connection element depends on the roof pitch.

The bending of the sheet metal of the connecting element is rounded and / or folded or bent in any other way. The connection elements are manufactured and provided according to the required width.

The plate of the connection element has a length (about 150-500mm), which depends on the roof pitch. This ensures that a seamless transition is provided between the object of the opening (e.g., window, fireplace) and the enclosure.

The edge of the lower connection element should be flush with the edge of the roof tiles and must be adapted to the existing roof tiles on site. The length of the sheet is shortened accordingly on site.

The system according to the invention comprises, in a preferred embodiment, at least one lateral rail of length L, the rail having an L-shaped profile having a first horizontal leg and a second vertical leg, the horizontal leg one or more protrusions to form one or more gutters, the bulges extending substantially along the length L of the rail.

The profile rails are used for profile extension of the connection profiles of the connection elements, if they are not sufficient in their length. In this way, the system according to the invention can be used for any length or depth of a roof opening.

The profile rails are prefabricated in terms of profile and length and also come in other areas, such as. in glass and window construction for use.

Preferably, the L-profile of the rail and the connection profile of the connection element are arranged overlapping. As a result, a waterproofing transition between the rail and connection element is created. It should be arranged in the roof assembly respectively higher-lying element over the other element in order not to affect the flow of water through protruding profiles and to prevent the accumulation of water in this area. Preferably, the upper connection element should be arranged above the profile rail and the profile rail above the lower connection element. The vertical leg of the L-shaped profile of the rail can be adapted in the region of the connection profile according to the shape of the connection element. This is done by cutouts or recesses corresponding to the rounding / edging / shape of the bent sheet metal of the connection element. The rounded and / or folded sheet metal is inserted and fastened in this area of the profile rail.

The attachment of the rail with the connection element is done either by seaming, soldering, welding or gluing or by other joining techniques.

On the horizontal leg of the L-profile of the rail can be along the length of an insulating rail made of flexible material, whereby a seal is achieved to the side roof structure. This forms a connection and termination to the lower transition region of the final tiles and causes a seal to be created to protect against water, snow, dust, etc.

The system according to the invention may preferably comprise a cover element for connection to an element of the system, wherein the cover element has a groove in which a Abziehklebeband is attached. The release tape is centrally kinked in the groove and thereby covers both sides of the groove. The cover element covers the transition to the adjacent roof surface and for this purpose consists of a flexible, adaptable material that can adapt to the roof surface and thereby creates a watertight transition between the enclosure and the roof surface. The cover may further comprise a corrugation for the discharge of water. The masking tape is protected from damage and dirt by a protective film before mounting on the roof. Before the gluing with the system element, the protective film is removed, the cover is moved to the system element and glued to it.

The invention also includes a cover member for connection to an element of a system, wherein the cover member has a groove in which a Abziehklebeband is attached. It is preferably an adhesive tape used, which can be used even at low temperatures.

Preferably, the cover is connectable by introducing the edge of the system element in the groove. The kinked arrangement of the adhesive tape in the groove, both sides of the introduced edge are glued.

In addition, the groove of the cover may be formed as a double fold.

In addition to creating enclosures of roof openings, the rainproof side closure and connection of roof surfaces can also be realized by the present invention. For this purpose, a profile rail of length L is used, wherein the rail has an L-shaped profile having a first horizontal leg and a second vertical leg, wherein the horizontal leg has one or more protrusions to form one or more gutters and the bulges extend substantially along the length L of the rail.

The rail according to the invention can be used in addition to the described enclosure of a roof opening for every possible form of rainproof completion of lateral roof areas (so-called verge) and the subsequent discharge of water. The conclusion of a gable or dormer structure is possible under other special roof shapes. The L-profile of the profile rail forms the connection to the respective roof surface and is suitable for every type of roof covering (for example roof tiles, slate, sheet metal, etc.). In addition, the system according to the invention can be used for roofs with a slope (from 22%) up to pitched roofs for each roof angle of inclination, are applied to the roof tiles in the rule. Through the use of several rails the completion of the ridge can be achieved and in the case of a roof surface with different angles of inclination (for example with a tail roof, towing roof, mansard roof, etc.) or with a possibly odd lateral roof run. The rails are adapted to the different roof pitch, or to the respective roof course.

In addition, any form of lateral closure and possibly connection to other adjacent roof surfaces or structures is possible. Thus, the connection of the roof surfaces of densely juxtaposed buildings can be generated. On the one hand, the rain-proof transition from one roof surface to the other can be created here. On the other hand, the connection can be created from a roof surface to the adjacent wall at different building heights.

Also, the connection of the roof surface to other artificial or natural walls, such as walls or rocks conceivable.

Preferably, the horizontal leg of the aforementioned rail can have at least two lobes to form gutters and the lobes can extend substantially along the length L of the rail and a bulge is substantially lower than the at least other bulge. The different height of the bulges to produce an adaptation to the final roof tiles. It is e.g. the middle area of the final roof tiles on the lower protrusion of the profile rail on and off at the outer bulge. As a result, the roof surface is held in a plane and there are no distortions, or height intervals on the final roof tiles.

In this case, the vertical leg of the rail, for example, a length of about 200 mm. With regard to the horizontal leg of the rail, the first section from the vertical leg to the first bulge on a length of about 50 mm and from the first bulge to the second bulge on another section of about 50 mm. From the second bulge to the end of the horizontal leg has a length of about 30 mm. The first bulge has a height of about 50 mm, the second bulge a height of about 3 to 7 mm at the end of the upstand or the envelope.

In a preferred embodiment, the rail on the horizontal leg of the L-profile of the rail along the length of an insulating rail of flexible material. This forms a connection and termination to the lower transition region of the final tiles and causes a seal to be created to protect against water, snow, dust, etc.

• Bereitstellen eines Profils das ein L-förmiges Profil aufweist, das einen ersten waagrechten Schenkel und einen zweiten senkrechten Schenkel hat, wobei der waagrechte Schenkel mindestens zwei Ausbuchtungen zur Bildung von Wasserrinnen aufweist und die Ausbuchtungen sich im Wesentlichen entlang der Länge L der Profilschiene erstrecken und eine Ausbuchtung wesentlich niedriger als die mindestens andere Ausbuchtung ist.

The invention also provides a method of confining roof areas comprising the following method steps:

• Providing a profile having an L-shaped profile having a first horizontal leg and a second vertical leg, the horizontal leg having at least two lobes for forming gutters and the lobes extending substantially along the length L of the rail and a Bulge is much lower than the at least other bulge.

Attaching the profile to the lateral boundary of the roof surface.

Connecting the roof surface, wherein the final roof tiles rest on the lower protrusion of the rail and the covering area of the tile is cut off at the side or laterally near the higher bulge.

As already mentioned, the side rail consists of a prefabricated standard profile. The width of the metal sheet of the connection element is made according to the individually required width information at the factory. The upper and lower connection elements are moved and fastened on site. If necessary, the connection elements are pushed onto or under the profile rails and fastened. Alternatively, the respective upper and the lower connection plate are already connected in advance to a respective profile rail, which thus form two parts. These two parts are connected on site, wherein the upper connection element is pushed with the already connected rail over the lower connection element and the rail connected thereto. The overlap of the connections between the rail and the connection element causes the desired rain protection. The assembled skirt is flush with the opening to form a rainproof finish.

The system according to the invention has the advantage that the mounting of the enclosure contrary to the conventional procedure does not necessarily have to be done by a person skilled in the art. On site, only the depth and width of the opening and the inclination of the roof for the corresponding creation of the connection plates must be recorded. In addition, a time-consuming adaptation on site is no longer required, so that the preparation can be created in parallel to the construction project.
