Definitions

  • the invention relates to a roof made of self-supporting, large-area roof elements, in which the adjacent main beams of adjacent roof elements are non-positively connected to one another.
  • the modules each have three rafters, of which the middle one is twice as strong as the rafters. These three rafters are then plywood, fiberboard or the like. firmly connected. These module elements have hinges in the gable area and also in the pliers area, which enable the module elements to be folded together, in order to enable transport on normal roads when larger spans are formed.
  • the known design it is possible to assemble roofs from module elements, but the known design has the disadvantage that, due to the collapsibility of the modules, the interior of the modules is not possible, since the space for the folded pliers or the like. is needed.
  • the formwork panels i.e. the plywood or fiberboard, must be able to absorb the entire transverse load of the module elements, since the individual rafters are connected to each other only by this outer cladding panel.
  • the invention is based on the object of forming a roof from self-supporting, large-area elements, in which the roof elements have a high internal strength, so that when the roof elements are manipulated during construction, the roof elements cannot be weakened or damaged in any way.
  • this is achieved in that the main girders are connected to one another by secondary girders running transversely or obliquely to them and, if appropriate, parallel girders lying parallel to the latter, the entire roof structure with outer skin, interior cladding and optionally thermal insulation and vapor barrier being attached to the main girders.
  • Roof elements are thus achieved, through which a finished roof is already present after the same has been placed on the supports, and large spans can also be roofed over, since the roof elements have such a high internal strength due to the secondary beams or the optionally provided transverse ties that the manipulation of the Roof elements can not be damaged.
  • the entire roof structure can be placed on the building site as a unitary piece, which enables extensive prefabrication of the roof elements within the manufacturing company, so that only a small amount of time is required in relation to the actual work to be carried out on the building site.
  • the roof can also be set up in unstable weather conditions, with the result that a completely tight roof is present immediately after the roof elements have been laid on.
  • the main girders and optionally also the secondary girders can advantageously be made of wood, in particular glulam, or lightweight steel profiles. This creates a construction that is easy to handle by weight and with which even larger spans can be overcome without difficulty. It can at the Support facing ends of the main carrier support beams are provided, which protrude from the main beams in the direction of the support. This enables training in which the actual roof element can be mounted lifted off the support, which results in a corresponding increase in the internal clearance height of the building. For a particularly easy installation, the support beams can be pivoted relative to the main beams and can be fixed in the desired position.
  • the adjoining main girders of adjacent roof elements can be non-positively connected to one another, which means that the individual main girders can be dimensioned weaker, since the two main girders joined together largely add up in terms of their load-bearing capacity.
  • an inventive roof higher loads such as snow loads and.
  • an angle enclosing, with their insides facing each other, in particular opposite roof elements can be connected to each other by a drawstring. This applies on the one hand to so-called throat beam roofs or normal gable roofs, as well as with regard to half-timbered structures and possibly roof window lanterns.
  • Fig. 1 shows a diagram of a prefabricated roof element during assembly.
  • FIG. 2 is a bottom view of the roof element according to FIG. 1.
  • Fig. 3 is a cross section through the same.
  • FIG. 4 shows another embodiment variant of a roof element according to the invention, partially cut open.
  • Fig. 5 is a cross section through the roof element with connected neighboring roof elements.
  • the roof element according to the invention consists of main beams 1, 2 which run along the edges 3, 4 leading away from the supports. These main girders 1, 2 are connected to one another by secondary girders running transversely or obliquely to them and, if appropriate, transverse ties 6 running parallel to these secondary girders. On the main beams 1, 2, the outer skin 7 as well as the inner cladding 8 and optionally thermal insulation 9 are also provided. A vapor barrier 10 is arranged between the thermal insulation and the outer skin of the roof.
  • the main girders 1, 2 are made of wood in the present exemplary embodiment, with glulam being particularly suitable. This is because glued laminated timber can be assigned the appropriate properties, which are necessary for the main girders, through appropriate choice of wood, layer and adhesive. Instead of wood, steel lightweight profiles or the like could of course also be used.
  • the roof elements are laid man to man, the main beams 1, 2 coming into full contact with the main beams 1 ', 2' of adjacent elements.
  • These main beams 1, 2 'and 2, 1' are then connected to one another in a force-locking manner, as a result of which the main beams lying against one another function as uniform beams.
  • the underside of the main carrier can then be covered with cladding 11 or the like.
  • the outer skin 7 of the corresponding prefabricated roof elements located on the upper side is then designed such that it can either overlap partially overlapping the neighboring element or that the abutting edges of the outer skin 7 are sealed off from one another. This can be accomplished using conventional sealants.
  • a vapor diffusion layer 10 is provided below the outer skin and serves as a vapor barrier.
  • a roof is created with such prefabricated elements in that the on a wall ring Precast elements by means of a suitable lifting device, such as a crane or the like, are placed. Since the prefabricated elements already carry all the necessary parts of the roof, these prefabricated elements only need to be connected to one another so that the roof is ready. Because of the short working time at the construction site, it is possible to build roof structures that are quickly sealed even in late autumn or even in the winter months. The great weather dependency when creating roof structures is thus eliminated.
  • the elements can form the sole load-bearing structure, but can also represent secondary structures, supported by additional load-bearing elements.
  • FIGS. 6 to 15 relate to single-span girders (FIG. 6), a throat beam roof (FIG. 7), with a drawstring underneath being shown in broken lines as an alternative variant.
  • Fig. 8 shows a joint rod pull radial again.
  • a three-joint frame (Fig. 9) can be created.
  • FIG. 11 shows a two-articulated arch
  • FIG. 12 shows a three-articulated arch
  • Fig. 13 shows a radial truss
  • Fig. 14 shows a conoid.
  • 15 shows a two-part radial frame. 7 and 13 are held together by drawstrings 12, to the extent that certain pent roof designs or truss designs are achieved.
  • the roofs can have additional support beams 13 (FIG. 6, FIG. 9, FIG. 15), with which multi-joint designs are achieved. These support beams also serve to achieve higher attics.
  • This type of support bracket also makes it easier to set up the individual roof elements due to the multi-joint system.
  • the supports on which the roof is placed are designated 14 in FIG. 6.
  • a roof element designed according to the invention can be used for a large number of roof systems, all of which have the advantage that the entire roof is already transported to the construction site in finished components, which means that the time required and the resulting costs on the construction site how crane hours, scaffolding, higher risk to workers, etc. can be saved.
  • the shape of the individual roof elements can also be chosen as desired or can be easily adapted to the respective requirements.
  • the essential thing is that the entire roof structure envisaged is integrated in one element, which as such is already brought close to the construction site and then adjoining roof elements are connected to one another to form a tight roof.
