DESCRIPTION " SYSTEM. INCLINED COVER AND INSULATING PANEL FOR INCLINED COVERAGE SYSTEMS " The invention relates to an insulation panel for an inclined cover system with a body of insulation material, having a flat base surface and a top surface, as well as side surfaces, which connect the base surface to the top surface , the base surface being aligned anti-parallel to the top surface, the top surface having at least one slope relative to the base surface, the body of insulation material being sandwich-shaped and having at least a first layer with the heat-insulating and / or sound-absorbing property, in particular of mineral wool, preferably of rock wool. The invention further relates to an inclined cover system for a flat or low slope cover composed of an insulation layer, preferably with the interlayer placement of a leaf seal, in particular an air retention, on a laying layer , in particular on a roof frame of trapezoidal sheets, the insulation layer being composed of insulation elements in the form of panels and being covered with an outer roof liner, and wherein at least a part of the insulation elements in the form of a panel has a body of insulation material with the sandwich design and having at least a first layer with heat-insulating and / or sound-absorbing properties, in particular mineral wool, preferably rock wool.

Insulating elements and roof constructions are known in various prior art productions. A flat or low slope cover in question in the present context usually consists of an insulating layer 2, preferably disposed with an interlayer of a sheet seal over a laying layer. The insulation layer is further covered by an outer roof liner. The laying layer may have a structural roofing system.

A structural system of a flat or sloped roof consists of assemblies, mounted at regular distances from each other or supported on the outer walls. In order to achieve wide surfaces without supports, it is sought to achieve large gaps. The assemblies consist, for example, of steel profiles, steel lattice constructions, concrete beams, laminated beams or hollow wooden beams. Mothers or rafters are fixed transversely to the legs on their respective struts. At least in the case of structural wooden systems, these support elements are also referred to as mother-rails. The following executions relate to roofs of mothers, but should also be applied to rafter roofs.

As a support for the roof structure, it is used on-site molded concrete roofs, finished concrete parts, solid wood or wood products, as well as trapezoidal sheets. Formulations of wood-derived products are limited to panels with sizes of 2.5 m x 2.5 m. The trapezoidal plates have limitations in terms of the respective measures due to the transport. The metal roofs are profiled in yards with optional lengths of a coil, which is also in principle possible for trapezoidal sheets of the support construction. By a corresponding molding of its cut, the strength moments of the trapezoidal sheets may vary within wide values, or the thicknesses of the sheets may be adapted to the shapes of the sections. The common spans of the trapezoidal plates as supports with multiple spans are about 6 m. 3 The distinction is made between flat and inclined roof surfaces, as well as between those used and those not used. Stagnant water is considered detrimental due to the loads associated therewith in the supports and the structural system of the cover, but in particular in terms of the cover seals. Since in the precipitations gaseous compounds may be originally dissolved in the atmosphere, they lead, due to their higher boiling temperatures than water, to enormous reductions in the pH value upon drying. The moisture adhere to dust, dirt, seeds and favors the formation of algae, as well as the growth of plants with the associated production of humus or organic acids. Organic and inorganic acids can attack roof seals. The formation of crust is enough so that the seams of connection between different roof seals, considered in most cases fragility points, are attacked and damaged.

In order to prevent precipitation accumulation, roof supports or structural systems should already be planned for roof structures with a slope of 2% (1,15 °). Sloping roofs are special constructions and require special measures in order to avoid or mitigate the risks caused by stagnant water. However, it is expressly stated in the guidelines for flat roofs that stagnation of water on slopes up to 3 ° (~ 5%) can not be avoided. The precipitation water should be drained on a short path. In the case of roofs with a low slope up to 5o, an internal drainage is often carried out through roof drains, which are at low points on the surfaces to be drained and must be at least 50 cm away from roof structures or 4 other infiltrators of the roof seal. Conductive gutters for drainage of water should have a sufficient slope. Water drainage from the roof should not itself form thermal bridges. They need regular maintenance and are therefore free access.

Covered areas not used are not intended to be used for long periods of time, use for traffic or for breeding. They are intended for general maintenance and conservation purposes only. In terms of weeding, however, a distinction must be made between intensive and extensive weeding, the latter corresponding physically from construction to previously common gravel loads.

The roof structures should normally have a heat insulating layer to meet the requirements in terms of limiting the introduction of thermal energy.

A generic roof structure usually consists of a support, for example of trapezoidal sheets, in an air retention with a water vapor diffusion braking effect, in an insulating layer of mineral wool insulation material, preferably of roof insulation panels of rock wool and a rubber or plastic (rubber elastomeric) roof seal that is anchored with screws through the insulation layer on the trapezoidal sheets.

In the production of air retentions, thin polyethylene sheets having a thickness of only about 100 Âμm are often used which are loosely placed on the upper struts of the trapezoidal plates and are not bearable as a whole. A certain support capacity is in turn presented by strips of elastomers lined with foils and glued on the upper struts of the trapezoidal plates. 5

The various roof sealing materials will no longer continue to be differentiated, and are generally termed roof stopper strips, even if prefabricated screens of, for example, elastomers are used.

Mineral wool insulation materials consist of synthetic, vitally-solidified fibers which are partially bonded with reduced amounts of most often organic binders, such as formaldehyde-urea resins or phenolic resins of hard-plastic hardening . In order to permanently hydrophobize the insulation materials, they are further impregnated with additives, such as oils or resins.

The market distinguishes between insulating materials of glass wool and rock wool. The two types have different chemical compositions of the fibers and are therefore produced in different processes or with different devices. Rock wool insulation materials contain up to about 35% by mass of non-fibrous particles, whereas glass wool insulation materials are largely free of them. In any case, special rock wool insulation materials are also available, containing no non-fibrous particles or containing only a few non-fibrous particles. Moreover, recycled fibers having contents up to about 2 to 25% by mass are mixed in most rock wool roof insulation panels, which are normally only loosely incorporated in the flakes of the primary fibers and contribute practically nothing to increase the mechanical properties of the insulation material.

The rock wool insulating materials are therefore differentiated according to the respective thermal resistance of the insulating materials of glass wool and other mineral wool insulating materials. The rock wool insulation materials comprise mineral wool insulation materials having a melting point of 1000 ° C according to DIN 4102 part 17.

For the production of a heat-insulating layer, according to DIN EN 13162, factory-produced mineral wool insulation materials are used. The compressive stress of these mineral wool insulation materials is 40 kPa with a 10% compression set. In order to achieve this compressive stress with the least possible use of material, that is to say, also with weight savings, the strips of continuous fibers impregnated with additives and mixed with unbound binders are compressed during the manufacturing process in the direction vertical and in the horizontal direction. The individual fibers or agglomerations of primary fibers are folded in the direction of conduction and on themselves. Transversally to this, layers are formed to a large extent arranged horizontally, which means that in this direction the flexural strength is much greater than in the conduction direction. An increase in binder contents is excluded because of the risk of loss of the flame retardant power of the insulation material, as for example, for cost reasons.

In order to take advantage of the anisotropy of the mechanical properties in the case of the roofs in question in the present context, the roof insulation panels are designed in the form of supports with multiple spans, that is, with the maximum measures, as far as possible, transversely to the profile of the roofs. trapezoidal plates. This type of trapezoidal plate has free spans between the upper struts larger than 150 mm. To bridge these gaps, minimum thicknesses of 120 mm mineral wool roof insulation panels are required in the flat roof guidelines. According to a previously used measuring formula, based on flat fiber insulation panels in relation to the two large top surfaces, the free half-gap was calculated as the minimum thickness between the upper struts of the trapezoidal profiles of steel.

The rock wool roof insulation panels also include non-fibrous components and recycled fibers with total bulk densities of about 130 to about 170 kg / m 3, which may correspond, after removal of the non-fibrous particles, to liquid apparent densities less than 90 kg / m3 or greater than 70 kg / m3 of primary fibers, including binders. The use of large-format roof insulation panels measuring, for example, 2 m long x 1.2 m wide.

The top surfaces of the rock wool roof insulation panels responsibly react to loads when paving or passing with hand pallet trucks, sack trucks, platform trolleys. Both the profiles of the shoe soles and the wheels of the transport vehicles, as well as the wheeled wheels of the platform cars, lead, in addition to pressure loads, also to great efforts of cutting of the surfaces in question. In the case of a paving or the passage of vehicles in the areas on the lower struts of the trapezoidal plates in the longitudinal direction, there will be a worsening of the detrimental effects of these loads. Rainwater flowing to the unprotected top surfaces of the roof insulation panels weakens, with their hydrolyzing interactions, the often-employed thermosetting resins and the structure of the insulation material. In addition, almost natural resistance losses occur due to relaxation effects within the rock wool insulation material.

With an apparent bulk density increase to about 180 kg / m 3 to about 220 kg / m 3 within a layer having a thickness of about 10 to about 25 mm, beneath the large top surface above , the resistive capacity of the roof insulation panels is increased and the specific loads of the insulating material structure are reduced due to more favorable force application.

By properly arranging the laying and use of appropriate means of transport, it is possible to avoid the transport of heavy piles of parts produced from roof insulation panels and their damage. In the case of work to be carried out later, as in the case of finishing joints to parapets, fireworks, intersections and / or other adjacent elements, in the case of incorporating illumination balloons and roof water drainage, etc. , it is necessary to further design pressure compensation panels. However, the planning of these protection measures is usually not carried out since, in general, the associated organizational and financial costs are avoided.

In addition, unused roof surfaces must be regularly accessed for cleaning and maintenance work. Maintenance work includes, among others, the control of water drainage or the disposal of tanks. In addition, access to unused roof surfaces is necessary for the maintenance of, for example, ventilation and air conditioning equipment, antennas, lightning rods, advertising boards, smoke extraction equipment and / or lighting bulbs, as well as cleaning them. In this case, rails are formed which are identified by damaged roof insulation panels. In order to avoid such damages, for example, mats or panels of rubber grains, on which concrete plates or photoelectric warning grids may be placed, or the latter are additionally placed on poles on the concrete slabs. 9

Another problem with flat or sloping roofs is the flow of precipitation, including water resulting from thawing. In most cases, stagnation of water on the roof seal can only be prevented with a slope of the roof frame supports by about 30 °. The disadvantage has been that even in the case of new constructions structural roof systems are planned and constructed without sufficient slope, or that their permissible deflection is adversely affected. The permitted flexion of the trapezoidal plates is 1/500, which in the case of usual spans of about 6,000 mm makes even 12 mm. For the mothers and the asses one must consider push ups of this order of magnitude.

The lows of the partial surfaces provided by the mothers and the asses show only after the entire covering structure has been finished, including planned loads. The positions of these low points can vary even through atmospheric conditions, such as snow accumulation. Only after determining the low points, therefore a series of normally additional roof drains are determined. These additional jobs and devices are costly. In order to avoid costs, drainage of water from the cover preferably is placed near the mothers or near the asses, and thus almost next to the highest upper lines of the entire roof construction.

In order to effectively achieve a water flow towards a few drains of water from the cover, there are provided insulated roofing insulation systems which are further placed on the insulation layer and which, for example, in paired arrangement, form a gutter In order to prevent the stagnation of water in this gutter and in order to conduct the precipitation to the drainages of the cover, there are additionally arranged ribbed inclined cover systems, which have a structure always paired, so as to give rise to a raised central rib, while two obliquely descending side surfaces form flutes with the top surfaces of the inclined cover systems. Between two adjacent roof drains, two corrugated sloped roof systems are preferably arranged relative to each other so that the precipitation is conducted in opposite directions, i.e., to the respective roof drains.

The insulation elements of inclined roof insulation systems are taken into account in calculating the heat penetration resistance of the roof structure. However, in order to avoid thermal bridges, in particular for sufficient dimensional stability of the roofing system inclined on the trapezoidal plates, in order to achieve the required carrying capacity, a thermal insulation layer is generally required as a composite support preferably by insulation panels of large-format rock wool roof. Sloped roof systems can also be placed on existing roof structures, therefore old roof structures.

In order to limit the height of the inclined roof insulation systems, they are placed against each other on grille roof surfaces and form raised elevations with respectively a first row and respective interconnecting gates. Inclined roof insulation systems can be placed close to the delimiting elements such as parapets, fire breaks, superstructures and other intersections. In most cases, however, there are placed inclined roof panels which form a sloped plane from the delimitation. This plane is also commonly designated as counter-tilting if there is in turn a flat roof structure, that is, a counter-tilt.

Current tilting systems consist of a series of rock wool shaped bodies, the large outer top surfaces of which are inclined with respect to the generally horizontal laying surfaces. The angles of inclination do not exceed most of the time due to the interlayer of insulating material which increases greatly with a larger angle of inclination, and especially for cost reasons, 1.15 ° (~ 2% inclination). The molded bodies of rock wool are adjusted to each other in terms of their heights and widths. After reaching a certain height, other molded bodies of rock wool are placed on a planar insulation panel in order to be able to reach greater heights with a smaller number of molded bodies.

The insulation panels of sloped roofs of reduced thickness may be formed briefly by insulation panels with inclined roof covering of parallelepiped rock wool and therefore have, in principle, the same structure as the insulating roof panels of rock wool. Thicker cover insulation panels of greater thickness are comprised of individual panel sections aligned perpendicular to the top surface of the cover, the side surface thereof being oblique cut according to the intended angle of inclination. With the above-perpendicular orientation of the mineral fibers in the panel sections, a higher compression tension is achieved or the possibility exists, with the same level of compression stress, of reducing the apparent density of the panel sections.

For use on the roofs described above, it is necessary that the insulation layers (heat insulating and / or soundproofing) be sufficiently resistant in dimensional and thermal terms, and that are resistant to paving and dimensionally stable as a support for the roof seal. The rock wool roof insulation panels provided for this purpose are used to largely prevent thermal bridges and for cost reasons such as insulation panels of prismatic, ie, parallelepiped, planes. Insulating panels of this type can be inexpensively produced, stacked, transported and placed without the expertise. For both cost reasons and also because of its greater carrying capacity, large format panels with measures, for example 2 m long x 1.2 m wide, are preferably used. Small size insulation panels measuring 1.25 m or 1.0 m long x 0.6 or 0.625 wide are only used for secondary surfaces or on solid substrates.

The top surfaces of the rock wool roof insulation panels are relatively sensitive to repeated mechanical loads, such as those occurring with paving or passing with handcarts, hand pallet trucks, loaded platform cars, etc. These general pressure loads are aggravated in terms of their effects due to the shearing effects of profiled shoe soles or tires. While, for example, bitumen strips with two application layers still have a certain pressure compensation effect and clearly lessen said shear stresses of the top surfaces, the same is not true of the use of thinner plastic strips and rubber.

The improved properties of the top surfaces of the rock wool roofing insulation panels, in particular with a higher resistance to paving, are achieved through a highly compact cover layer up to about 220 kg / m 3, up to about of 2 mm. The respective prolonged effectiveness depends however on the rigidity of the remaining body of insulation material. If this is reloaded, this cover layer will also be fractured into pieces.

Roof insulation panels should be distinguished from inclined roof insulation panels having a sloped surface in at least one direction. In the case of inclined roof insulation panels, which are incorporated, for example, into the flutes of inclined roof surfaces, the inclined surface can be bevelled to one side or the other side, in order to produce a double slope.

On the other hand, inclined roof systems consisting of individual inclined roof insulation panels having a width of 600 mm and a length of 900 mm in the inclination direction next to the base, it being possible to produce on the surface of the roof a slope of 2%. The thicknesses of the inclined cover insulating panels within this inclined cover system are between 40 mm and 184 mm. Due to possible damage in production, blanket insulation panels or other unprotected molded bodies are generally prevented from reaching a thickness of zero.

If the base length of this inclined roof system is to be increased, a layer composed of insulating panels of flat roofs is inserted, thus it is usually possible to proceed with a first insulating panel with a corresponding inclined roof.

In order to limit the thickness and volume of the inclined roof insulation panels for the production of a sloping roof surface, arc-shaped elevations are formed, whereby gutters are formed, where the water drains of the roof are formed. 14, pp. 1052338, 2, and 4 0285509 AI disclose insulating panels of cellular materials such as PU foams and polystyrene. DE 9213220 U discloses a sloped roofing system in which the same materials are used for roof insulation elements with different conceptions in terms of section geometry. From the prior art, the aim of the invention is to provide an insulation panel for an inclined roofing system which has improved mechanical properties and which can thus withstand high compression and shear stresses and, on the other hand, other, be suitable for the production of a sloped roofing system and a construction assembly associated therewith. Further, the object of the invention is to provide an inclined cover system for a flat or low slope cover which could be simply constructed with as few components as possible and which also has the necessary mechanical properties, in particular levels of resistance.

These objects are achieved with a generic insulation panel, the first layer being of mineral wool and the second layer being of a different material from that of the first layer with at least a greater flexural strength.

In terms of the inclined cover system according to the invention, these objects are achieved when the second layer has mechanical properties, in particular levels of compressive and / or flexural strength, different from those of the first mineral wool layer, and consist of a material different from that of the first layer, with at least a greater flexural strength.

Further features of the insulation panel according to the invention or the inclined roofing system according to the invention are derived from the respective dependent claims as well as from the following description of improvements and designs of the insulation panel and the inclined roofing system.

Thus, it has been found advantageous in the case of an insulation panel of the design according to the invention that the base surface is at right angles so that the side surfaces are perpendicular to each other. Insulating panels of this type are simple to lay on usual roof surfaces and can even be easily cut to size with the usual tools.

According to a further feature of the invention, it is envisaged that the second layer of the insulation panel is composed of a molded body of compressive and / or flexural resistant material, in particular a magnesia binder, for example Sorel cement , or mixtures of binders with magnesia binder. In this design, it has been found advantageous that a respective second layer is sufficiently resistant to compression, so that the insulation panel may be susceptible to paving and / or vehicle passage thereon, wherein the design of the second layer is composed of a magnesia binder also has the advantage that, in this way, the flame retardant properties of an insulating panel designed accordingly are not adversely affected.

Another improvement of this design provides that the at least first layer is rectangular and is arranged on a shaped body forming the at least second layer. Alternatively, it may be provided that the at least second layer is rectangular and is attached to a shaped body forming the at least one first layer. Thus, the invention provides that the first layer with heat-insulating and / or sound-absorbing properties, in particular mineral wool, preferably rock wool, is designed as a rectangular element, namely 16 as a panel of usual insulation material, and that the second layer layer, with mechanical properties different from those of the first, has a large flat top surface which is disposed with its entire surface on the large top surface of the first layer, the second top surface of the second layer being antiparallel oriented in relation to the large top surface of the first layer. In addition, it is possible that the insulation panel is composed of a first layer which has two large top surfaces, being oriented antiparallelly with respect to one another, so that on a large top surface of the first layer is applied to second layer with the mechanical properties different from the first, said second layer having a rectangular design. In the case of the last embodiment, use is made of the advantage that the first layer, for heat-insulating and / or sound-absorbing properties, is easily adaptable in particular in terms of its molding, by cutting off a corresponding layer like a molded body , for example, of a block of mineral wool, for example of rock wool.

In the case of an improvement of the insulation panel according to the invention, it is provided that the body of insulation material has at least one side surface oriented parallel to the slope, which is aligned with an angle deviating from the right angle to the surface of base. Another improvement provides that the side surfaces have a height of at least 5 mm, so that the insulation panel is composed, over its whole large top surface, of an area, namely a layer, with heat insulating and / or soundproofing properties and an area, namely a second layer, with high levels of compressive and / or flexural strength. In this way, the heat-insulating and / or sound-insulating properties of such an insulation panel are maintained over its entire seating surface, for example, on a sloped cover.

Preferably, the first layer comprised of mineral wool has a fiber orientation towards its large top surface. This design has the advantage of being increased the compressive strength of this first layer.

According to a further feature of the invention, it is envisaged that the second layer composed of compressive-resistant material may have at least one sheet reinforcement of woven, non-woven, glass fiber, plastic and / or natural fibers. This measure also serves to improve the mechanical properties, in particular the levels of compressive strength and / or flexural strength of the second layer, whereby this second layer also has at least a high flexural strength even having a relatively small thickness . The second layer, made of compressive strength material, according to another feature of the invention, has additional soluble glass, organosodium silicates (ormosils), siliceous glass and / or plastic dispersions or emulsions.

According to a further feature of the invention, it is envisaged that the second layer, consisting of a compression-resistant material, has at least one inner reinforcement of textile fibers, glass wool and / or mineral wool, in order to improve their respective mechanical properties, and it has been found advantageous that the second layer, consisting of a compression-resistant material, is made up to 40% by mass, preferably up to 25% by weight of textile fibers, glass wool and / or mineral wool.

The layers to be interconnected of mineral fibers and, for example, of Sorel cement are preferably bonded thereto or laminated in overlapping with one another in a working step.

According to a further feature of the invention, it is envisaged that the second layer composed of compression-resistant material, in particular of magnesia binder, exhibits fine particulate additives of brucite, aluminum hydroxide and / or titanium oxide, in particular with up to 25% by mass.

Preferably, the two layers are flush with each other to form a plane body in the area of the side surfaces, so that an insulation thus formed presents insulating panels, arranged with the full extent of the respective surfaces sides together.

According to another feature of the invention, it may be envisaged that the second layer having the top surface protrudes at least with respect to a side surface of the first layer showing the base surface. In this case, the second protruding layer may lie on an adjacent insulation panel and thus cover the joint area of two adjacent insulation panels. The second protruding layer thus serves as a seal for the transition area between two adjacent insulation panels of a roof system.

According to another feature of the invention, it is envisaged that the second top top layer layer is of a material having a thickness of about 2 mm to 25 mm, preferably about 3 mm to 10 mm. A second layer having this design thus has a material thickness sufficient to, in particular in connection with the feature set forth above, form a layer sufficiently resistant to compression and / or bending. In addition, the thickness of the material is chosen so that the total weight of the insulation panel is within values that allow handling by a person. In addition, with these material thicknesses, insulation panels of large dimensions are possible, without having to resort to the machinery in their placement in a roof system.

In an advantageous embodiment of the invention, it is further provided that, on the top surface of the body of insulation material, in particular on the second layer, a cover, in particular in the form of a non-woven plastic randomly oriented fiber . This design has the advantage of improving the bond between the two layers through the cover, for example a nonwoven of random plastic fibers having the effect of a reinforcement.

An improvement of the insulation panel according to the invention provides that the second layer resistant to compression and / or bending has different thicknesses depending on the mechanical loads to which it is subjected during use. For example, the second layer may have a greater thickness in the passage and / or access areas, these areas may also be implicitly recognizable in visual terms by, for example, a special color, a special granulation or the like.

In terms of the above-mentioned covering, it may additionally be provided that it protrudes over at least one side surface, preferably two adjacent side surfaces of the body of insulation material, preferably over the second layer showing the top surface. In this case, the cover may at least partially cover an adjacent insulation panel, this cover having in this case a sealing function. Moreover, the cover may also be designed as a self-adhesive at least in the protruding area, thus being easily collatable to the cover of an adjacent insulation panel or to an adjacent insulation panel.

Furthermore, according to another feature of the invention, it is envisaged that at least one side surface of the first layer, having the base surface, is at least partially designed with a coating resistant to compression and / or flexion, coating preferably of material identical to the second compressive and / or flexure resistant layer. An insulation panel of this type is particularly suitable for the areas of the edges of a roof covering, the layer being to protect both the top surface of the insulation material and a side surface against damage.

In order to improve an insulation panel according to the invention, it is provided according to another embodiment that the first layer having the base surface is designed in several parts by segments. Preferably, the segments of the first layer are glued together and / or interconnected through the second, bending and / or compression-resistant layer. Further, it may be provided that the segments lie on a support layer and are preferably attached thereto, in particular bonded thereto. This embodiment can be improved by, for example, the carrier layer being of suitable material for thermal insulation and / or soundproofing purposes, in particular mineral fibers.

According to another feature of the invention, it is provided that the body of insulation material has a first layer with heat insulating and / or sound-absorbing properties, in particular mineral fibers, a second layer disposed on the first of a compressive-resistant material and in particular of mineral fibers, and finally a fourth layer of a material resistant to compression and / or bending, in particular a binder of magnesia, a third layer placed thereon with heat insulating and / or sound-absorbing properties, in particular of mineral fibers and, finally, to the bending, in particular of a magnesia binder. This insulation panel is thus designed as a sandwich element and has very good mechanical strength levels and at the same time extraordinary properties in terms of thermal insulation and / or soundproofing.

A previously presented insulation panel is improved if the first layer is conceptually compressible. Through the compressibility of the first layer, it is possible to easily adapt this insulation panel to irregularities of the laying layer which receives the insulation panel.

It has been found that in the case of such an insulating panel, the production of the second and fourth layers with an identical material is favorable, thus simplifying the manufacturing process.

Particularly advantageous embodiments of the tilting roof system according to the invention are set forth below.

Preferably, the inclined roofing system according to the invention is improved by placing, on the laying layer, an insulating element in the form of a panel, having at least one side surface, aligned with an angle deviating from the right angle in relative to a top large top surface in the insulation layer and a lower large top surface in the insulation layer of the insulation element, and in that the lower large top surface is conceptually larger than the top large top surface of the insulation element.

Water flow systems are known for controlled runoff of rainwater. In accordance with the invention, use is made of insulating elements on an oblique surface. With such insulating elements having an oblique surface, inclined cover systems are conceived, which serve, for example, to drain the pluvial water into a water flow system of the inclined cover system.

According to an improvement of the inclined cover system according to the invention, it is provided that the angles of the molded parts or the insulating elements arranged in overlap are smaller with respect to the laying layer. As a result, in the case of a plurality of shaped parts or of several overlapping insulating elements, the orientation of the surfaces is at an angle obliquely to the horizontal in the form of a circle arc or a circle arc section.

The molded parts are preferably bonded, in particular glued, to the side surface of the insulation element disposed adjacent to them and / or to the insulation element disposed in the layer placed below, so as to ensure a composite of the different components of the inclined cover system.

It is further envisaged that the insulating element is bulged in the area of its top large top surface in the insulating layer and / or preferably arcuate in segments. With this design, the function of the insulation element in terms of the precipitation flow, in particular of the rain water, is essentially improved for a roof water flow system, and in particular the accumulation of water on top of the top surface of the cover.

Additionally, it may be envisaged that the side surface of the insulation element in the form of a panel is also concave, in particular concave, with an angle deviating from the right angle to a large top top surface in the insulation layer and a large surface of in order to also achieve the aforementioned advantages in the case of such an insulating element for an inclined cover system. 23

According to an improvement of the inclined cover system according to the invention, it is provided that at least one top surface disposed adjacent the side surface of the molded part and / or the adjacently placed insulating element has at least one less in partial areas, a compression-resistant and / or flexural-resistant layer. This layer protects the molded part or the insulation element from damage caused by sheeting or also from atmospheric conditions, for example precipitation and / or solar radiation. An improvement of this design provides that the compressive and / or bending resistant layer extends over a portion of the side surface so as to also protect against damage and atmospheric conditions.

It has further shown that it is favorable for the compressive and / or flexural resistant layer to extend over the lateral surface to the laying layer and which is preferably placed over a partial area of the laying layer. This design is also intended to protect the building elements of the inclined roofing system against mechanical stress such as compression, bending and shearing, as well as against atmospheric conditions, in particular precipitation and / or high solar radiation.

According to another feature, it is provided that the insulating element has two large top surfaces, in turn presenting a layer of a material different from that of the first layer, with heat insulating and / or soundproofing properties, with at least one greater resistance to flexion. Insulating elements with this type of design may in particular also be used in areas which serve for the passage and / or access of persons and vehicles to the inclined cover system.

According to a further feature of the invention, it is provided that a large top surface of the body of insulation material is designed as a flat base surface, arranged anti-parallel with at least one slope relative to a second large surface of top of the insulation body, the body of insulating material having side surfaces, which connect the base surface to the second major top surface. In principle, it is thus possible to use insulating material elements in a tilted roofing system according to the invention, as described above, in the form of, for example, an insulation panel. Accordingly, it is also possible to realize the features and designs previously set forth by the insulation panel according to the invention in the case of bodies of insulating material which are used in such an inclined cover system, so that in terms of the advantages of the bodies insulating material or insulation material elements of this type reference is made to the advantages of the insulation panels described above.

37 is an insulation panel for a sloped roof system in side view; Figure 1 shows a section of a tilted roofing system for a flat roof cover 1, comprising a roof cover and a roof terminal 2, having a top surface 3, on which is a cover sheet 4, in particular a retention of air. On the sheet seal 4 there is an insulating layer 5 of a series of insulating elements 6 in the form of panels, the insulating elements 6 being aligned in several juxtaposed series. In Figure 1 it is still possible to recognize a central area 7 of the insulation layer 5, in which central area 7 is further provided with water flow openings 8. The central area 7 of the insulation layer 5 is formed by inclined insulating panels 9, additionally placed on the insulation elements 6 and the design of which will be described below. From Figure 1, it can be recognized that the insulating elements 6, which are designed in the form of panels, have a top surface 10, which is anti-parallel oriented with respect to a second top surface 10 arranged opposite, this second top surface 10 being over the seal 4. In this case, the top surfaces 10 of the insulation elements 6 have a series of coincident alignment, the top surfaces 10 of the insulation elements 6 passing a series leveled on the surfaces of top 10 of the insulation elements 6 of an adjacent series. In all, the insulating elements 6 form, with their surfaces 10 on one side of the central area 7, a top surface inclined towards the central area 7, thus the precipitation water, appearing on the top surfaces 10, is drained in the direction of the central area 7.

In Figure 1 it can be seen that there are two water outlet openings 8 spaced apart from each other in the central area 7. On both sides of the water flow openings 8 are inclined insulating panels 9. The inclined insulating panels 9 between the two openings of water flow 8 form a corrugated inclined cover system which is designed so that the precipitations are conducted in opposite directions, i.e., directed towards the water outlet openings 8.

The inclined insulating panels 9 are in this case on insulating elements 6, which are a component of the insulating layer 5.

In Figures 2 and 3 there is an insulating element 6 shown both in perspective and in side view. The insulating element 6 consists of a body of mineral fiber insulation material connected with a binder. The body of insulation material forms a first layer 11 of the insulation element 6 and has a large top surface 12. A second layer 13 is seated on the body of insulation material. The second layer 13 is essentially rectangular in shape and shows the large layer 11. top surface 10 of the insulation element 6. The large top surfaces 10 and 12 are antiparallel to each other. In this way, the large top surface 10 has an inclination to the large top surface 12.

The two layers 11 and 13 have different mechanical properties, namely levels of resistance to compression and bending, the first layer 11, namely the body of insulating material, having a lower compressive strength compared to the second layer 13. In addition to the surfaces 10 and 12, the insulating element 6 has side surfaces 14, which are in turn aligned perpendicularly, two lateral surfaces 14 being parallel therebetween and giving rise to a base surface perpendicular to the insulating element 6, whose The second layer 13 and the first layer 11, in particular the body of insulating material, are glued, the insulating element 6 being composed of the body of insulating material and the second layer 13 as a single piece. Figures 2 and 3 show that the body of insulation material 29 has, in the area of its side surfaces 14, at least a height of 5 mm, the entire second layer 13 being covered below by the body of insulation material. In order to improve the compressive strength of the insulation material body or the second layer 13, it is envisaged that the first layer 11 will have a fiber orientation towards the surface 12. In addition, the second layer 13 has a flat fiber reinforcement which are incorporated in the second layer 13.

Finally, it can be seen in Figures 2 and 3 that the side surfaces 14 of the body of insulation material and the side surfaces 14 of the second layer 13 merge levelly, whereby the respective side surfaces 14 of the body of insulation material 11 and the second layer 13 are planarly shaped.

An improvement of the insulating element 6 shown in Figures 2 and 3 can be seen in Figure 4. In addition to the elements of construction of the insulating element 6 according to Figures 2 and 3, the insulating element 6 has, according to Figure 4, on the surface 10 of the second layer 13, a cover 15 in the form of a nonwoven of plastic randomly oriented fibers. The cover 15 may be glued to the face on the surface 10 or, alternatively, protruding over the side surfaces 14, and may thus be placed on an adjacent insulating element 6 in the case of juxtaposed insulating elements 6.

Figures 2 to 4 show embodiments of the insulating element 6 with a slope of the surface 10 in a direction relative to the surface 12. In contrast, Figure 5 shows one embodiment of the insulating element 6, having a construction in accordance with in accordance with Figures 2 and 3, yet has two inclinations of perpendicular orientation relative to one another in accordance with the arrows 16 of the top surface 10 with respect to the top surface 12. Figure 6 shows another way of an insulating element 6, being designed with a triangular section, the top surface 10 being arranged opposite a right angle in a design with the second layer 13. It is possible to use such an insulating element, for example on the edge of a cover, in particular in the area of a parapet 32. Figure 7 shows another design of an insulating element 6 in combination with an insulation panel 17 , having a rectangular design and consisting, for example, of mineral fibers bound with binders. The insulating element 6 has a trapezoidal section and has a second layer of a bending-resistant material, which extends on a top surface, oriented parallel to the large top surface 12, of the body of insulation material, and a side surface 14, which is oriented at an angle deviating from the right angle to the top surface 12. The insulating element 6 has a height which coincides with the height of the insulating panel 17. With this design, it is possible to design the insulating element 6 with a second layer 13, which extends over the large top surface, opposite the large top surface 12, the body of insulation material or the first layer 11, and thus lying on a large top surface 18 of the insulation material panel 17 adjacent. Through a adhesive, the second layer 13 may further be attached to the large top surface 18 of the insulation material panel 17.

In the Figures 8 to 11 described below, different inclined insulating panels 9 are shown.

In Figure 8 there is shown a first embodiment of an inclined insulation panel 9, which is designed as magnesia molded body, and has two side surfaces 19 joined at an angle, as well as base surfaces 20, of which only a base surface 20 is shown in Figure 8. The inclined insulation panel 9 is wedge shaped, the side surfaces 19 being joined along a line 21 and being oriented from this line 21 downwardly towards the base surfaces 20 , the side surfaces 19b from the line 21 being inclined downwardly relative to a flat laying surface.

In Figure 9 there is an alternative design of an inclined insulation panel 9, in which is located a base 22 between the base surfaces 20, which has a flat laying surface 23, which serves to place on a surface 3 of according to Figure 1 or on flat insulating elements 6. Between the base 22 and the base surfaces 20 there are contemplated return points which are normally designed to correspond to an inclination of the insulating elements 6 in the area of the respective top surfaces , such insulating elements 6 thus being able to be evenly disposed in the space between the base 23 and the base surface 20. An alternative design of the inclined insulating panel 9 according to Figure 8 is shown in Figures 10 and 11. In this there is provided a body of insulating material, on the side surfaces 19 of which there is a camad to 13 of compression-resistant and bending-resistant magnesia, which are bonded to the body of insulating material 11. The body of insulating material 11 consists of mineral fibers bound with binder and thus has very good properties of thermal insulation and soundproofing. Preferably, the body of insulating material 11 is produced as a compressed molded part, the second layers 13 being compressed with the body of insulating material 11.

Between the two second layers 13 there is a groove 24 which, in correspondence with the side surfaces 19, is inclined towards a tip 15 of the inclined insulation panel 9. Figure 12 shows another embodiment of a cover 1, in a roof frame construction, having a plurality of trapezoidal plates 26 and a sheet cover thereon. On the cover sheet 4 are insulated panels 27 with a rectangular design. The insulation panels 27 are disposed together with respective side surfaces, between two series of insulating panels 27, insulating elements 6 representing another embodiment of the invention.

The insulation elements 6 are sandwich-shaped and have a first layer 11 in the form of a body of insulation material, a second layer 13 and a third layer 28. These insulation elements 6 have a material thickness of about 30 mm . The first layer 11, designed as a body of insulation material, and the third layer 28 are composed of mineral fibers bonded with binders, and it has been found advantageous to place the mineral fibers in at least the first layer 11 designed as a body of insulation material, with an orientation perpendicular to the large top surface. The second layer 13, which is intermediate in the sandwich element, consists of a panel of magnesia resistant to bending and solid and hence pressure distributor. The thickness of this second layer 13 is calculated so that the third layer 28 is slightly protruding with its top surface 10 on the top surface formed by the insulation panels 27. Following a load in the direction normal to the top surface 10 , this insulating element 6 is pressed in such a way that the surface 10 descends maximum up to the level of the top surfaces formed by the insulating panels 27. Thus, a much greater compressibility is not provided. In this case, it has been found advantageous to design the third layer 28 having a material thickness of about 10 to about 15 mm, so as to ensure its function as a flexible spacer or separator layer. Unlike the foregoing description, the third layer 28 may also obviously be composed of hard foam or non-woven panels of randomly oriented plastic fibers. This third layer 28 further serves as a protective layer for the magnesia panel, which is protected from damage by sharp edges and atmospheric conditions. Figure 13 shows the arrangement of an insulating element 6 according to Figures 2 and 3 in an inclined cover system, which is composed of a lower layer of insulation panels 27 and inclined insulating panels 8 laid over. Between two inclined insulating panels 8 is an insulating element 6, so that the inclined surfaces of the insulating element 6 and the inclined insulating panels 8 form a plane. The area of the insulating element 6 is in this design as an access area and can be visually identified by a clear deviation of the second layer 13 which

In Figure 14 another example of an insulating element 6 is shown, said insulating element 6 having a body of insulating material with two large top surfaces 12 of parallel orientation therebetween. On top of the two large top surfaces 12 there is in turn a second cover layer 13 composed of a magnesia panel, which magnesia panel is adhered to the body of insulation material. In the layers 13 are reinforcing elements, for example of glass, plastic and / or natural fibers, found laminated with magnesia binders. The laminated layers have a thickness of about 0.5 mm to about 30 mm, and material thicknesses between about 1 mm and 10 mm have been found to be particularly suitable. Obviously, the two layers 13 may have different thicknesses of material or be reinforced differently. The layers 13 may, in a working step of producing the body of insulation material, be structurally laminated or additionally placed after a hardening of the binders in the body of insulation material.

Subsequently, different tilting roof systems are described, which are shown in Figures 15 to 31 and in which it is possible to use insulating elements 6 according to Figures 1 to 14. Figure 15 shows a cover 1 with a roof terminal 2, which has a top surface 3. On the top surface 3 there is a sheet seal, not shown in more detail, as shown, for example, in Figure 1 and which is identified by the numeral 4.

On the top surface 3 there are two overlapping layers of panels of insulating material 17, in the right half of Figure 15, of rectangular shape. The panels of insulating material 17 of the two overlapping layers that are offset from one another in terms of their side surfaces 19, resulting in a level design. At the levels 29 formed in this case are insulating elements 6, which have a triangular section and which have a surface opposite a right angle, the surfaces of the insulating elements 6 being arranged in adjacent levels with the same alignment in a plane.

In the top layer of the panels of insulation material 17 there is a system of inclined insulating panels 9, consequently designed with oblique surfaces that deviate from the horizontal. As inclined insulating panels 935 are in question, for example, also inclined insulating panels 9 shown in Figures 8 to 11.

Unlike the right half of Figure 15, the left half of Figure 15 shows an alternative design, which differs from the right half design of Figure 15 in that the panels of insulating material 17 are designed as a single piece with the insulating elements 6 Consequently, these panels of insulating material 17 are distinguished from a rectangular design in that a side surface 19 is aligned at an angle which deviates from the right angle in relation to the large top surfaces 18. Obviously, this may also occur to be applied to more than one side surface 19. Two other embodiments are shown in Figure 16, so that in the right half of Figure 16, adjacent to two overlapping insulation panels 17, there is an insulating element 6, which essentially has a triangular section and has, on its side surface facing the panels of insulating material 17, a level 30 serving to receive the topmost panel of the two panels of insulation material 17, whereby the top panel of the two panels of insulation material 17 protrudes from the bottom panel of the two panels of insulation material 17 towards the insulation element 6.

In the left half of Figure 16 there is shown another alternative design providing an insulating element 6, which extends with the respective height over two layers of the panels of insulating material 17 and further presenting a sloped surface 31, which is in opposition with the side surface 14, which is joined to the face of the side surfaces 19 of the insulation material panels 17. In addition to the above-described embodiments, there is also the possibility that the insulation layer 5 is composed of more than two layers of panels of insulating material 36. Obviously it is also possible and is provided in the embodiment according to Figure 16 the provision of inclined insulating panels 8 on the top layer of panels of insulating material 17.

In Figure 17 it is still possible to recognize that the insulating element 6, which is attached, for example, to a parapet 32, has a greater inclination than the insulating element 6 disposed on the opposite side of the water flow opening 8. The two inclinations serve to rapidly and directly flow the eventual precipitation water from the water outlet opening 8, which extends with a pipe section 33 through the roof terminal 2.

Furthermore, it is possible to recognize that the layer 13 terminates in the face with the large top surface of the panels of insulating material 17, arranged next to the insulating element 6, resulting in a flat top surface of the insulation layer 5, free of rebounds, which could lead to stumble. Figure 17 further shows that the layer 13 of the insulating element 6, disposed in the area of the parapet 32, is guided over the large surface of the insulation element 6 up close to the tube section 33, the layer 13 having a partial area directly over the top surface 3 or over a sheet seal placed thereon. With this design, the sensitive area of the corners of an insulating element 6 of mineral fibers is further protected against damage.

In Figure 18 there is shown another embodiment of a cover 1 with a roof terminal 2, composed of several trapezoidal plates 26 and a sheet cover 4 above. Figure 18 shows an insulating element 6, composed of a first layer 11 designed as a body of insulation material, and a second layer 13 of cement of insulating material 17, which is composed of mineral fibers connected with binders. Sorel layer placed on the first layer, the second layer 13 having a higher compressive strength and a higher flexural strength compared to the first layer 11 and thus to the body of insulation material. The insulation element 6 has an inclination, the insulating element 6 being close to the face with its side surface 14 to the adjacent insulation panel 17, thus a seamless transition between the large top surface of the insulation material panel 17 of the second layer 13 of the insulating element 6.

Furthermore, Figure 18 shows the combination of a panel of insulation material 17, composed as usual by mineral fibers bonded with binders and an insulating element 6 arranged to the side, which has the sandwich design and has a body of intermediate insulation material 11, which has on its two large top surfaces respectively a second layer 13 of Sorel cement. From these insulating elements 6 with the second two Sorel cement layers 13, a simple and effective path and / or access is achieved in a cover 1. Obviously, this is also possible with inclined insulating elements 6, provided that the The inclination of the insulation elements 6 is such that it is possible to access or walk safely on such a surface.

Another embodiment is shown in Figure 19. Figure 19 shows around the combination of insulation elements 6 with panels of insulation material 17, the panels of insulation material 17 being designed in accordance with the previous embodiments, in particular with the Figure 17. Furthermore, the roof 1, shown in Figure 19, is designed in accordance with the roof 1 according to Figure 18.

In Figure 19 there is shown in the left half 38 a first embodiment of an insulating element 6, composed of a rectangular layer 11 of mineral fibers connected with binders in the form of a body of insulating material. The body of insulation material has, on its large top surface facing the sheet seal 4, a second layer 13 of Sorel cement. This second layer 13 is also rectangular and has a reduced thickness. Finally, another layer 13 of Sorel cement is located on the opposing top surface of the body of insulation material, which has, in a partial area, an essentially triangular section, with the consequent formation of a slope in the area of its large surface and, in a partial area, a rectangular section. The insulating element 6 thus formed forms an inclined insulating panel 9.

In the right half of Figure 19, there is shown an alternative design of an insulating element 6 of this type, there being further below the second lower layer 13 another layer 28 of mineral fibers bonded with binders. Another difference with respect to the embodiment according to the left half of Figure 19 consists, in the case of the embodiment of the insulating element 6 according to the right half of Figure 19, in that the body of insulating material 11 is designed with a first layer 11 as a molded body and is designed with a slope in a partial area of its large top surface, facing the roof terminal 2. The second layer 13 laid over is designed as the thin layer 13 of Sorel cement. The embodiments according to Figure 19 may be arranged in combination with each other on a roof terminal 2, so that the central area of the juxtaposed insulating elements 6 forms a flat and / or flat access surface, while the edges of the juxtaposed insulating elements 6 are designed with an inclination such that the two inclinations converge and thus cause the precipitation water to flow into the central area of the two juxtaposed insulating elements 6.

Another embodiment of a cover 1 with inclined insulating panels 9 is shown in Figure 20.

On a roof terminal 2, designed in accordance with the roof terminal 2 in Figures 18 and 19, there is a first layer of panels of insulating material 17. Between two panels of insulating material 17 is an insulating element 6, which has a first layer 11 designed as a body of insulation material, and a layer 13 placed on the first of Sorel cement, the second layer 13 of Sorel cement being aligned away from the cover terminal.

In the first layer of panels of insulating material 17 there is, in partial areas, a second layer of panels of insulating material 17, of which there is shown in Figure 20 only one panel of insulating material 17 in the right half of Figure 20. A this insulation material panel 17, there is attached an inclined insulation panel 9 which has, in the area of its large top surface having an inclination, a second layer 13 of Sorel cement, which extends to the area of the large top surface of the adjacent insulation panel 17, the large top surface of the insulation panel 17 being partly covered by the second layer 13. The second layer 13 of this inclined insulation panel 9 covers the entire large top surface and extends to the area of the second layer 13 of the insulation element 6 below.

Further, Figure 20 shows a system of inclined insulating panels 9, which are in turn designed with two layers, these inclined insulation panels 40 respectively having a top surface with an inclination, said top surface being covered by a second layer 13 of Sorel cement. The inclined insulating panels 9 are designed so as to form in juxtaposition with each other a uniform and flat inclination. In this case, the inclined insulating panel 8, directly next to the second layer 13 of the insulating element 6 disposed in the first layer of the panels of insulating material 17, is spaced from an inclined insulating panel 9 arranged in opposition, thus forming a trough 34 between these two inclined insulating panels 9 disposed with the second layers 13 on the second layer 13 of the insulation element 6 in the first layer of the insulation material panel 17, which channel serves to flow the precipitation water into a flow opening water not shown in detail. In Figure 21 there is shown a section of a cover 1 in perspective. On a continuous insulating layer 5, composed of panels of insulating material 17 and insulating elements 6, there are arranged inclined insulating panels 9; in turn 2 superimposed inclined insulating panels 9, respectively designed in the form of a section of a pyramid, forming an inclined element 35.

The inclined elements 35 are spaced apart between them through the insulating layer 5, the inclined elements 35 with the lower inclined insulating panels 9 being in turn joined together to an insulating element 6, these insulating elements 6 being arranged in a line with their narrow sides together to each other so that the insulating elements 6 form, with their second Sorel cement layers 13, a passageway and / or an access.

An embodiment comparable to Figure 22 of a cover 1 is shown in Figure 22, it being possible to recognize that the second layers 13 lie flat on a lower layer of panels of insulating material 17, and it may of course also occur here a connection between the second layers 13 and the panels of insulating material 17, this connection being concretized during construction, i.e. during the production of the cover 1. Furthermore, Figure 22 shows another insulating element 6 with a large top surface which has a slope relative to the large top surface of the panels of insulating material 17, this large top surface being covered with a second layer 13 of Sorel cement. The inclination is oriented towards the inclined elements 35, both the inclined elements 35 with the inclined insulating panels 9, as well as the insulating element 6 having the large inclined top surface being aligned in a central area 7, however the two inclinations one different degree of inclination.

In Figure 23 there is shown a cover 1 with an insulating layer 5 of panels of insulating material 17. In the conceptually rectangular insulating panel 17 is a system of inclined insulating panels 9 in a partial area. The inclined insulating panels 9 form a flat inclined surface. In the central area of the system of Sorel cement inclined panels 9 or arranged with a layer 13 of Sorel cement. This area forms a passage and / or an access (for people and / or vehicles). In this case, it can be recognized that the system of inclined insulating panels 9 has several series of inclined insulating panels 9 juxtaposed, the series alternately displaying one or two inclined insulating panels 9 with a second layer of Sorel 13 cement. The insulating panels sloping joints 9 of the adjacent series are still disposed with the undercut joints. 42

Another design of a cover 1 can be seen in Figure 24. An insulation layer 5 consists of lathe panels of insulating material 17 having a rectangular shape. On the panels of insulation material 17 are, in turn, inclined insulating panels 9, which form two systems which flow the water in an area of a gutter 34, its inclination being directed towards the gutter 34.

In the gutter 34 there is a third system of inclined insulating panels 9, which are designed as sandwich elements, and thus presenting a body of insulating material designed as the first layer 11 with a sloped surface. A second layer 13 of Sorel cement is located on the inclined surface, the two layers 11, 13 being interconnected.

In Figure 25 is an improvement of the design according to Figure 24, showing Figure 25 only two inclined systems 36, 37, which are arranged on panels of large format insulating material 17. The inclination of the inclined systems 36, 37 is with the two aligned perpendicularly to one another, wherein a first inclined system 36 sits with its base point adjacent the side surfaces 14 of the second inclined system 37. Inclined systems 36 and 37 may be designed in accordance with the embodiment according to Figure 24.

Additionally, in the transition between the first inclined system 36 and the second inclined system 37, there are corrugated elements 38 of mineral fibers bound with binders, which prevent the accumulation of precipitation water in this transition area, this precipitation water being drained through of the corrugated elements 38 in accordance with the inclination of the inclined insulating panels 9 of the inclined system 37. It is to be mentioned that all the insulating elements 6, 43 inclined insulating panels 9, panels of insulating material 17 and insulating panels 27, as well as inclined elements 35 and / or corrugated elements 38 described above conceptually have one or more layers, there being at least one second layer 13 of Sorel cement or a similar compressive and / or resistant to flexural strength, the above mentioned elements being in principle passable flooring and / or access (by persons and / or vehicles), without damaging or destroy the other bodies of insulation material provided for these elements.

An embodiment comparable to the embodiment according to Figure 25 of a tilting system 37 is shown in Figure 27. In contrast to the embodiment according to Figure 25, the embodiment according to Figure 27 provides that the corrugated elements 38 are an integral part of the inclined insulating panels 9. The inclined insulating panels 9 and the corrugated elements 38 are thus designed in the form of shaped bodies.

Likewise, Figures 30 and 31 also show corresponding inclined systems 36 and 37, Figure 30 showing an inclined system 37, which is designed with an inclination in two opposing directions. Figure 31 shows an inclined system 36 of this type, which is designed in a partial area with a two-way inclination, while another partial area has an inclination in only one direction, the inclined system 36 for which different inclined insulating panels 8 with corrugated elements 38 arranged together thereto in single piece form.

Another advantageous design of the cover 1 is shown in Figure 26. It is possible to recognize an insulating layer 5 of panels of insulating material 17, on which there is a second insulating layer 5 of panels of insulation material 17, this second layer insulating material 5 composed of thinner insulating material panels 17. The two insulation layers 5 are not designed with the same surfaces. Instead, the upper insulation layer 5 is shorter than the lower insulation layer 5. On the front sides of the last panel of insulation material 17 and the upper insulation layer 5 there is an inclined insulation panel 9 having an essentially triangular section, which has a large surface, on which is a second layer 13 of Sorel cement . Moreover, the inclined insulating panel 9 consists of a body of insulating material forming a first layer 11.

On the above-described insulation panel 17 of the upper insulation layer 5 is another inclined insulation panel 9, which corresponds essentially to the previously described inclined insulation panel 9, and thus has around a body of insulation material as the first layer 11, and a second Sorel cement layer 13, which is disposed on an inclined top surface of the body of insulation material. To this inclined insulating panel 9 are joined other inclined insulating panels 9, these adjacent inclined insulating panels 9 being composed of individual lamellae of insulating material 39, having a fiber orientation perpendicular to the large top surfaces and interconnected through the second layer 13 of Sorel cement. The direction of the longitudinal axis of these lamellae of insulation material 39 is thus essentially perpendicular to the large top surfaces of the body of insulation material 11 formed therefrom. Depending on the anti-fog requirements, the different lamellae of insulation material 39 may also be bonded together. Overall, it is possible with this design to achieve an inclination with a large length of a cover 1 without a series of different inclined insulating panels 9 being necessary, since a large part of the inclined insulating panels 9 are composed of lamellae of insulating material 39, having, for example, an identical design in terms of the respective thickness of the material. A custom cut of these lamellae of insulation material 39 may be carried out in the yard. The design of such type of inclined insulating panels 9 serves to reduce the costs of constructing a sloped cover system.

In figures 28 and 29, there are shown again inclined systems 36 or 37, with Figure 28 showing two inclined systems 36 on the two sides of an insulating element 6 on a body of insulating material as the first layer 11, and a second layer 13 of Sorel cement. The inclined systems 36 are on panels of insulating material 17, which form an insulating layer 5.

In FIG. 29 angles of the inclined systems 36 and 37 are further shown. The angle α in this case denotes the inclination of the inclined system 37, while the angle β designates the inclination of the inclined system 36. In this case, the angle α is greater than than the angle β.

In Figures 32-37, different designs of a second layer 13 or of insulation elements 6 with a second layer 13 are finally shown. Figures 32 to 37 serve to explain the layer previously described in particular as second layer 13 of cement of Sorel. The second layer 13 may for example consist, according to Figure 32, of a magnesia laminate panel, having at least one flat reinforcing layer composed of glass, plastic and / or natural textile fibers. The fibers may be interwoven, interlaced or interconnected using binders. They have a loose structure, in which the binder can enter or be forced into easily. The flat reinforcing means may be used variably from one location to another.
