Definitions

  • the invention relates to a dormer consisting of a front wall, two side walls and a roof, the front wall and optionally also the side walls and the roof comprising windows.
  • Such dormers can be prefabricated on the one hand and then placed on the roof in the assembled one-piece condition.
  • the dormer windows can be assembled and assembled on site.
  • both the roof part and the two wall parts are prefabricated from a sandwich panel, which consists of a dimensionally stable insulating layer, one flat side of which is connected to a relatively rigid support layer and the other flat side of which is connected to a cover layer.
  • DE 87 13 597 U1 also discloses a prefabricated dormer which can also be fitted in one piece and which consists of an outer shell made of fiber-reinforced plastic and a heat insulation layer. The inside of the outer shell is provided with laminated supports that have a sandwich structure.
  • the object of the present invention is to provide a dormer that can be assembled easily and quickly, is stable and that can be aligned in particular during assembly, so that unevenness in the attic or differences from non-parallel roof beams can be compensated and an exact alignment of the dormer Local conditions such as roof tiles are possible.
  • the support frame which - apart from the cross strut (s) - consists of at least two frame parts, each of which has a length-adjustable support frame.
  • the individual frame parts can be pre-assembled at the factory.
  • unevenness in the attic can be compensated for using the two length-adjustable support frames.
  • the entire dormer height can be set. If necessary, differences of roof beams that do not run exactly parallel to one another can be compensated for by means of crossmembers of different lengths or also adjustable in length.
  • the dormer can be moved at least slightly - for example, areas of 150 mm - by means of the length-adjustable support frames both in the forward direction and in both lateral directions, so that an exact or desired horizontal and vertical alignment of the dormer is possible.
  • the dormer window is easy and quick to assemble, whereby a front, preferably prefabricated and possibly including windows and roller shutters, is first attached to load-bearing building roof elements, after which various individual elements such as cross members, side elements or side windows are arranged or used.
  • the length adjustability of the support frame is achieved in that it is designed as a hollow profile, preferably as an aluminum hollow profile, with an inner profile, in particular a rectangular or C-shaped profile, being held on the bottom so as to be telescopically displaceable.
  • This construction provides an extremely simple and inexpensive construction option for a length-adjustable support frame.
  • the inner profiles of the support frames are preferably attached to the attic of the building via fastening flanges or a base plate, so that a firm hold of the support frame and thus also of the dormer window is ensured.
  • the cross members are also each designed as a hollow profile, preferably an aluminum hollow profile, wherein A reinforcement profile can be inserted and anchored over the entire length of the same. Since the aforementioned outer hollow profile often has sufficient buckling stiffness, but does not have sufficient bending stiffness, such stiffening is necessary in order to prevent deflection of the cross member. This is particularly important if the roof rests on and is supported by the cross members.
  • the reinforcing profile preferably projects above the free end of the crossbeam and is used for fastening to load-bearing structural elements of the building roof. It is possible to have the reinforcement profile protrude by the manufacturer with a certain length over the free end of the crossmember, a displacement range of 150 mm being sufficient in most cases. When building the support frame, the length of the cross member is then reduced to the desired size. Alternatively, it is possible to arrange the reinforcing profile so that it can be moved telescopically in the cross member. In both cases, the non-positive connections between the crossbeam and the reinforcement profile are made by screwing screws into the holes provided in the crossbeam at the factory.
  • the two supporting frames are connected to one another - in particular at the factory - by an upper and a lower cross strut via corner connectors.
  • the lower cross strut replaces a wood change usually arranged in the building roof between the rafters.
  • the dormer construction thus replaces at least part of the previous building roof construction while avoiding the need for a separate timber change construction, and a particularly stable dormer window is also achieved.
  • the upper and lower cross struts also ensure easy attachment and installation of the front window.
  • a roller shutter box in particular a mini roller shutter box, is arranged, this is arranged between the upper part of the window frame and the upper cross strut. If the dormer roof is to be supported by the upper cross strut, this can, like the cross beams, comprise a hollow profile into which a reinforcing profile can be inserted and anchored.
  • the assembly is particularly easy if the individual support frame elements and the window or roller shutter are connected to one another by screws, in particular thread-cutting screws. This makes it possible to remove the dormer window on the one hand and to subsequently replace individual elements.
  • a multiple coupling namely a side-by-side arrangement of individual dormer windows, is also possible, with adjacent front sides of the individual dormer windows adjoining each other. Side walls are then only necessary on the two outermost dormer windows.
  • Triangular windows or side parts without windows which preferably consist of insulated sandwich panels, can be used as side walls.
  • a particularly advantageous embodiment is defined in that the dormer roof can be fastened to the support frame, in particular to the cross members thereof, and the support frame itself can be fastened to supporting structural elements of the building roof by means of oblong holes. Due to the possible slight displacement of the fastening screws in the elongated holes, the roof can be tilted forward, for example, in small areas so that the rainwater can run off better. Furthermore, it is also possible to temporarily fix or attach the support frame to the roof beam in order to then, if necessary, be able to make slight displacements and an adjustment of the support frame both in the horizontal and in the vertical direction.
  • the outer profiles for the support frame and / or the cross strut and / or the cross member are designed as approximately L-shaped hollow profiles.
  • an insulating and compensating element that can be pushed back and forth parallel to the longer leg is arranged on the inside of the shorter leg.
  • this element ensures that there are no cold bridges between the outside environment and the interior of the dormer in the area of the support frames and cross members.
  • Other measures can also ensure the thermal insulation properties of the support frame and thus the dormer as a whole.
  • the displaceability of the insulating and compensating element allows optimal adjustment of the support frame and adjacent window elements, even if the two elements are misaligned, there is no direct path from the outside environment to the interior of the dormer window, through which wind and water could get into the interior of the dormer window .
  • the L-shaped hollow profile and the insulating and compensating element preferably form a rectangular cross-section, the aforementioned unit having an unchanged width over its entire length. It is therefore unproblematic to add elements adjoining the support frame to the inside of the L-shaped hollow profile.
  • a further insulating element on the narrow side of the long leg of the L-shaped hollow profile, which is on the inside in the assembled state. This further promotes the avoidance of cold bridges between the hollow profile and the adjacent dormer element.
  • the insulating and compensating element and the additional insulating element form corner insulation on the inside of the L-shaped hollow profile. This significantly increases the degree of thermal insulation.
  • the insulating and compensating element or additional insulating element which consists in particular of PVC, has hollow chambers.
  • the L-shaped hollow profile is preferably divided into two hollow profiles separated from one another by a partition. In addition to the better thermal insulation, this also results in good stability properties for the L-shaped hollow profile and thus the support frame.
  • expansion joint covers which extend in the axial direction on the outside on two diagonally opposite edges are provided on the L-shaped hollow profile or integrally therewith in continuation of the lateral boundary. These cover the butt line or the space between the L-shaped hollow profile and an adjacent construction element, for example a window. Arranging such expansion joint covers can also prevent water and air from penetrating into the spaces between the support frame and the dormer windows.
  • the expansion joint cover also makes it possible to align elements adjoining the support frame, for example a window.
  • the supporting frames can be disassembled into at least two components approximately halfway up and below the lower cross member. This makes it easy to handle the sometimes long support frames or, if applicable, the prefabricated front wall of the dormer during transport and in tight local conditions.
