Definitions
- the present invention relates to a roof structure with at least one an eaves or foot purlin and / or on a middle purlin and / or on one Ridge purlin supported basic construction according to the roof covering Preamble of claim 1 and a support and insulation element according to the preamble of claim 7.
- roofs for buildings such as Residential houses by laying so-called roof trusses made of load-bearing beams and rafters in their Basic construction is made between the rafters and / or on the rafters then insert or apply insulation.
- the Insulation mounted as so-called rafter insulation, the lower heat and Has air passage joints.
- the rafters with the installed or applied roof insulation form the basic construction of these roofs, which then form the roof covering wearing.
- the sub-trades completed first e.g. the sub-roof in shape a film covering are to be carried out by the sub-trades to be carried out below constantly exposed to the risk of damage.
- the lower layers generally require additional local work Cladding with plasterboard or embellishment with wooden straps, which then from subsequent craftsmen, e.g. the plasterer or carpenter are to be executed. This naturally leads to a costly and time-consuming roof construction.
- the laying of plate-shaped bodies is also particularly useful large format plates sometimes difficult because they can warp and therefore Bumps and arches occur.
- This problem is particularly with wood or Fibreboard known.
- a plywood structure is often used as a countermeasure chosen, but which is also not suitable to a curvature in any case prevent. Due to the delay of such panels, however, it is on when they are laid a base or a coupling to an already existing plate element required that the curvature be laborious with a certain application of force is overcome.
- This is particularly the case with supporting elements for a roof structure disadvantageous, since the roof slope is worked in an unfavorable area got to. If there are also bad weather conditions, this may be the case. even particularly dangerous and therefore partly hardly feasible.
- the document DE-OS 21 45 628 discloses a support and insulation element for one Roof structure in which the outer peripheral edge of a box-like Frame of a first support and insulation element has a hook section, which in an adapted hook section in the adjacent support and insulation element intervenes.
- the hook section of one support and insulation element is in the correct position to be placed over the hook section of the other support and insulation element.
- the hook sections so flexible and with Undercuts should be formed that the indentation of thickening of one Sidebar in the recesses of the other sidebar is possible, which makes results in a firm connection between two plates.
- the neighboring Support and insulation elements are first positioned exactly on the roof and be fixed and it is an additional assembly step to press into each other the hook sections required. This construction is therefore disadvantageous because large assembly effort and precise work is required.
- FR-A-2 586 729 discloses plate-like prefabricated components made of wood of walls of a prefabricated house. These prefabricated components or Tragund Insulating elements or wall panels are made up of flat, box-like frames. Its vertical edge, when installed, is made of upright wooden support posts formed, which have groove or tongue-like recesses. neighboring Support and insulation elements are screwed together with screws.
- FR-A-2 102 784 is a generic roof construction become known, with a supported on an eaves or foot purlin and a ridge purlin, the basic construction supporting the roof covering.
- This basic construction is from a series of side by side, butt-connected Support and insulation elements made, which are built from box-like frames are.
- the butt-jointed flanks of neighboring support and insulation elements have in the end faces of the wooden beams running transversely to the ridge in the middle area opposing, trough-shaped grooves on, together in cross section a hexagonal space between them form adjacent flanks, in which in turn a corresponding hexagonal planed plank spring is inflated.
- a dense design of the joints between two neighboring building boards is not possible.
- a wooden building board is known from DE-OS 1 303 625.
- This building board is made up of a box-like frame, which with upper and lower plates is covered.
- These upper and lower cover plates have at their frontal edges tongue-like or tongue-like with the tip pointing inward V-shaped Recesses on one side and corresponding with the tip pointing outwards V-shaped protuberances on the opposite end so that Adjacent cover plates lying on the frame in a horizontal direction with each other can be encountered.
- the flanks of neighboring building boards widen butted against each other, so that a tight design of the joints between two neighboring building boards is not possible.
- the present invention is therefore based on the object, while avoiding it the defects discussed above to further develop a roof structure such that a weather-resistant basic construction is made available for example, can be quickly installed in almost any weather using a construction crane can.
- the roof construction according to the invention enables for the first time an economical, efficient roof construction.
- the conventional roof structures in the Production of the basic construction until shortly before the roof covering and until shortly before the final completion of the varied inner surface Operations that are carried out on site with a high risk of errors, can thus be moved to the workshop for the first time and thus brought forward.
- a weather-resistant basic construction can be created. This happens Advantageous due to the quick, labor-saving laying of the prefabricated trundle Insulating elements using a construction crane, this step then almost is weather independent.
- the support and insulation elements can be easily opened and closed Interlocking can be applied to the purlins, leaving only one man to retract and possibly another man is needed to fasten it. These are significantly fewer Workers, such as those laying traditional, made of rafters and purlins formed roof structures are needed.
- the invention is preferably from the eaves or foot purlin to Continuous ridge purlin supporting and insulating element made of a hollow box-like Frame with insulation material provided.
- a support and insulation element is connected to the neighboring supporting and insulating element using a triangular or hook-shaped outer edge connected positively, the first Suspend the support and insulation element in the next support and insulation element.
- a positive or non-positive, tight connection is created because over the bevel of the triangular groove the edge-side tongue of the subsequently mounted support and Insulation elements in the groove on the edge of the pre-assembled support and insulation element slides in.
- This sliding slope of the invention, on the groove or on the tongue existing, diagonal fold enables a reliable, exact and fast Assembly.
- the mounted on the lower side of the hollow box-shaped frame for The interior panel facing the roof is preferably relatively dense and strong vapor barrier.
- the following between the legs of the frame in the generated hollow box arranged thermal insulation can be of the most varied Insulation materials are made. Insulation materials made of mineral fibers or are preferred Insulation boards made of cellulose packages Application.
- An air layer possibly overlying the insulation layer, forms another insulation element.
- a narrow wooden plate or Wooden strip can be applied to the legs of the frame. About that is one preferably somewhat softer, upper cover plate arranged, the lower Has vapor diffusion resistance like the bottom plate.
- This is water-repellent treated, e.g. siliconized, impregnated or with a water-repellent layer Mistake.
- the wooden strip can be chosen from particularly load-bearing wood, so to speak like the top half of a carrier, while the bottom half of one imagined Portrayed by the hard lower shell. This can be indicated if the softer or more breathable top layer or top plate is not so has a high static load-bearing capacity and nevertheless larger spans can be achieved should.
- the installation of a vapor barrier or barrier e.g. on the inside is also just as possible as the reinforcement of the lower layer by wallpapering etc.
- the water-repellent surface or the water-repellent one Coating should at least temporarily withstand wet loads. However, it needs do not represent a permanent roof membrane. Above this level it is now possible to The simplest form, any quick roofing with a suitable roof covering and also to apply the conventional tiled roof. Even the production of Flat roofs are therefore possible.
- the side bond can so that over the joints of the abutting and interlocking support and insulation elements do not draw in water, with a are preferably provided in the groove base seal.
- a fine, sealing, self-expanding cord is preferably used for this. In order to the air density is also significantly improved.
- the roof construction according to the invention differs in an advantageous manner for example by the following features compared to a conventional one Rafter Design:
- the frame can be made Beams or rafters.
- the side parts or Leg of the frame formed from two or three glued layers. This creates a frame that is particularly resistant to warping. This stands in contrast to traditional solid wood rafters, which can twist.
- the support and insulation element according to the invention no longer has any knobs (notches), with which the rafters are combed onto the purlins, but it preferably points attached, horizontally running strip-like cams or wart strips on the statically calculated and fixed accordingly and that on a correspond to the nipple attached to the purlin or in engage appropriate notches.
- the attached to the support and insulation element Wart bars can also be integrally formed on the frame.
- the outer dimension for the support and insulation element has a size of about 1.25 mx 6 m with a height of about 140 to 220 mm is particularly advantageous proved. This size is also easy in medium-sized companies Craft companies such as a joinery and / or carpentry.
- the width dimension and the length dimension are not fixed limited.
- the latter is preferably based on the depth of the house. It can therefore also very deep roofs are made. Roofs with a depth of 6 to 8 m or roofs with a depth of 8 to 14 m as well as roofs with a depth of 12 to 18 m can be easily realized with the roof construction according to the invention.
- the support and insulation element according to the invention should be at least a depth of approximately Bridge 6 m, which would then correspond to a house depth of about 11 to 12 m, which in the usual housing are usually required.
- the hollow box-like frame can protrude above the middle purlin, so that no ridge purlin is needed and instead the rims-side edges of two abutting support and insulation elements running against each other get connected.
- a triangular element or a triangular dam element screwed on from above with rod and hat profile can be provided.
- the support and insulation elements can be used for reinforcement in both Longitudinal direction as well as in its transverse direction between the hollow box-shaped Frame with stiffening middle rungs.
- the fastening is no longer as before by the insulation layer and Rafters generated with a long screw or an long nail, but over the wart-shaped pads on the underside of the support and insulation element and on the Pfettenobererseite.
- the quality of the roof structure can thus be after laying the support and insulation elements are checked from below, which is a clear one Reduction of the risk of injury. It must be in the laying itself no more man climbing around on the roof, making it the first time even when wet Weather-proof installation enables it to be done much faster can be than before.
- the roof structure according to the invention also includes due to the in a kind of series production of the support and insulation element considerable cost-saving rationalization advantages. Because at 1.25 m wide Parts of roof windows as well as standing dormer windows in the structure without any problems let there be no obstacles, even for more complex configurations.
- the support and insulation elements according to the invention in simplified form can also be used for large roof overhangs.
