EP2674545B1 - Insulation comprising insulating panels with groove and tongue joints along the edges - Google Patents

Description

The invention relates to an insulating board for insulation, preferably rectangular insulation board, in particular Untersparzendämmplatte, wherein the insulation board in one of its large areas has at least one groove for receiving strips and at their edges grooves and springs for positive connection with other insulation boards.

The increasing demands on the effectiveness of insulation, especially thermal insulation in the pitched roof area, have led to the fact that two-ply Vollsparrendämmungen be performed, otherwise the required insulation thicknesses as Zwischenparspendentämmung can not be realized.

The known Vollsparrendämmungen be designed so that between the rafters of the pitched roof directly under the roof formwork insulation (mineral wool, rock wool or plastic foam insulation boards) is attached. Thereafter, a construction battens (mostly made of wooden slats) is applied to the roof inside of the rafters. Between the slats of the construction battens a second layer of insulating material is introduced. Finally, a vapor barrier (foil) is attached to the construction battens, and the battens (mostly made of wood) are fastened under a covering to assemble fire protection boards.

Because of the wooden structure, unwanted thermal bridges, which lead from the outside of the roof into the roof interior, are created at the crossing points of rafters / construction slats.

Another disadvantage of the known insulation is the risk of moisture formation in the insulating material by condensation of water vapor, because moist, warm room air cools when flowing below the dew point and condenses water vapor. As a result of possible leaks in the vapor barrier or vapor barrier, moisture accumulates in the insulation material.

Vollsparrendämmungen are known in which a Untersparrendämmplatte is used, which is provided on the inside of the room with recesses for receiving mounting battens. These recesses are aligned parallel to the ridge line. Fastening the Untersparrendämmplatten takes place in the known insulation with screws or nails, which penetrate the mounting battens and the insulation boards and engage in the rafters ( AT 004 083 U1 ).

A disadvantage of these Untersparrendämmplatten is that the depth of the mounting slats receiving grooves usually corresponds to the height of the mounting battens, so that the mounting battens with the room-side surface of the insulation elements in alignment. Since wooden slats are usually used as mounting slats and they are not straight in the normal case, there is the disadvantage that uneven mounting slats protrude beyond the space inside surface of the insulation elements in the interior of the room. If the installation of the fire protection panels is carried out on uneven roof battens, the desired, even and flat surface of a room interior panel can not be produced. Furthermore, the width of the grooves receiving the mounting slats corresponds to the standard dimension of the mounting slats (wooden roof slats). This has two serious disadvantages. On the one hand mounting slats (wooden roof slats), which have only a slight excess in their width, can not be inserted into the grooves provided for receiving the same. If the mounting battens (wooden roof battens) on the other hand have an undersize, a central alignment in the grooves for the correct attachment of two fire protection plates, with the same bearing surface on the mounting battens at the abutting edges, is very difficult.

The, preferably made of foamed polystyrene, known Untersparzendämmplatten are provided at their abutting edges with clamping, single or double tongue and groove formations. A disadvantage of this clamped running tongue and groove formations is that the insulation panels can be very difficult to assemble due to the high frictional resistance of the insulating material and the large clamping surface of the tongue and groove formation. Another disadvantage of this clamping, one or two-fold groove and Federausformung is that in the assembled state an air permeability in the area of T or Kreuzstoßkanten the tongue and groove shape is given.

The invention has for its object to provide an insulation board and an insulation of the type mentioned, which allows easy installation and provides a reliable insulation.

This object is achieved according to the invention with an insulating board, which has the features of claim 1.

Preferred and advantageous embodiments of the invention are Subject of the dependent claims.

According to the invention, longitudinal recesses are provided on the edges of the insulating board, which form a vertical abutting edge groove in the region of the vertical abutting edges of adjacent insulating boards and a horizontal abutting edge groove for receiving strips in the region of the horizontal abutting edges of adjacent insulating boards.

With the invention, an insulation is provided in which Untersparrendämmplatten be used, which have the advantage that the slats do not protrude beyond the space inside surface of the Untersparzendämmplatte even when not straight or flat mounting slats.

Furthermore, the position and spacing of mounting battens or rails can be adapted to the different lengths of fire protection boards.

In an exemplary embodiment, the invention provides a thermal insulation, which uses a heat bridge-free Untersparzendämmplatte for the pitched roof and ceiling area, in which by a preferred training in tongue and groove area by clamping or gluing in the region of the abutting edges between adjacent insulation boards a wind and steam convection-dense layer is given. When using wooden slats as mounting slats, forms the space inside surface of Untersparrendämmplatte or form the mounting slats the support surface for fire protection panels or other cladding (interior space side), the mounting of fire protection boards is easy.

According to the invention, it is provided in a preferred embodiment that the depth of the mounting slats receiving groove exceeds the height of the mounting slats, so that even when using curved mounting slats only the flat, interior space surface of the Untersparrendämmplatte forms the support surface for fire protection panels or other panel, since the depth the groove exceeds the dimension of the mounting slats plus the extent of their deflection.

When using flat and straight mounting slats, the groove can also be designed so that the depth of the groove is less than the height of the mounting slats, so that only the mounting slats form the support surface for fire protection panels or other cladding. The space between the (sub-rafter) insulation boards and fire protection boards is advantageous in case of fire because heat from the fire boards can not be transferred directly to the insulation boards.

The space inside surface of Untersparrendämmplatten can be provided with a plurality of recesses in the central grid spacing of 50 and / or 100 and / or 200 and / or 400 mm for receiving mounting battens, four-sided rails or other rail. Thus, the mounting slats, square profile rails or rails can be positioned at the horizontal end of fire protection boards with a length of 2000 mm for their installation. Alternatively, the distance between the recesses for receiving the mounting slats, square rails or rails by their central grid spacing correspond to the dimensions of fire protection boards, so that they can be screwed at their horizontal ends without shortening and editing the mounting slats, four-sided rails or rails. This pitch (eg 200mm) allows to easily maintain the location of the attachment points (at least 100mm within the edge of the fire protection panel) for fixing fire protection panels.

It is advantageous if the recesses for receiving mounting slats are designed so that even mounting slats which under the standard width of mounting slats (wooden slats) or exceed centered in the groove for receiving mounting slats are positioned and remain adherent to the final mounting screw in its installed position , so that a "one-man assembly" is possible.

References to "horizontal", "vertical", etc. in this specification refer to the position of use of insulation boards, respectively.

According to the invention, in another embodiment of the invention, for example, provided that the width of the groove for receiving mounting battens is greater than the standard dimension of the width of mounting battens (wooden roof battens). On both side surfaces of the groove are in one preferred embodiment wedge-shaped, elastic projections be formed. The distance between the at the plane of the insulation boards perpendicular side surfaces of the groove opposite, wedge-shaped projections from each other is preferably smaller than the standard size of the width of mounting battens (wooden roof slats), whereby when inserting the mounting slats in the grooves a central positioning and clamping fixing the mounting slats takes place in the groove by the elastic, wedge-shaped projections on the side surfaces of the groove. These wedge-shaped projections serving for the central positioning and clamping of the mounting slats can be formed integrally, horizontally or vertically, continuously or only over partial areas, opposite or offset, on the (mutually facing) side surfaces of the groove for receiving mounting slats. The wedge-shaped, elastic projections which serve for the central positioning and / or clamping fixing of the mounting slats can also be designed semicircular or in any other desired form. The elastic projections described above may optionally also be formed only on a side surface of grooves.

When using flat and straight mounting slats or square profile rails, the depth of the groove on the space inside surface of Untersparrendämmplatten may be arbitrary, so that the mounting slats or square profile rails beyond the space inside surface of the Untersparrendämmplatten out into the room interior to between the space inside surface of Untersparzendämmplatten and To provide the fire protection panels or cladding an installation space for piping.

Elastic projections for clamping fixing the mounting slats or four-sided rails on the side surfaces of the groove can also, as described above, be formed only over portions of the height of the mounting slats or four-sided rails receiving groove.

Markings in the central grid spacing of 50 and / or 100 and / or 200 and / or 400 mm can also be applied or integrally formed on the space inside surface of the sub-rafter insulation panels in order to avoid time-consuming measuring of the distances between mounting slats to be mounted horizontally, quadrangular profile rails or mounting boards , provided on grooves for receiving or partially receiving mounting slats or four-edged rails can be dispensed with.

If the horizontally extending markings on the space inside surface of the Untersparrendämmplatten are spaced from the vertical abutting edges and thus a continuous smooth surface for masking by means of adhesive or sealing tape is formed, can be dispensed with depressions on the abutting edges of Untersparrendämmplatten. Furthermore, an installation level for piping is formed.

For fixing the fire protection boards also fixed in the Untersparzendämmplatten, rails (made of metal) can be used.

When using (metal) rails for attaching fire protection boards according to the invention, the space inside surface of Untersparrendämmplatte in an exemplary embodiment configured such that the grooves are formed as horizontally extending, slot-like grooves (recesses) in the space inside surface of the Untersparzendämmplatten, in which Legs of rails are inserted.

It is advantageous to make the slot-shaped grooves for receiving the legs of rails narrower than the thickness of the legs of rails, so that the legs of rails are clamped inserted into the slot-shaped grooves and the rails in the roof pitch and the ceiling adherent to the final Fitting are held in the Untersparrendämmplatten. As a result, a "one-man assembly" of the rails is made possible.

The legs of the rails and gegengleiche recesses on the space inside surface of Untersparrendämmplatte can also be designed such that the rails remain self-adhesive to the final assembly in the Untersparrendämmplatten.

By formed in one embodiment of the invention as horizontal slots grooves which are arranged in a central grid spacing of 50 and / or 100 and / or 200 and / or 400 mm, and to Receiving rails on the space inside surface of Untersparrendämmplatten serve, an exact fitting and positioning of the rails for securing the horizontal abutting edges of fire protection panels or panels is guaranteed without shortening the same on the inside of the Untersparrendämmplatten.

On the space inside surface of the Untersparrendämmplatten gegengleiche recesses for the rails can be optionally arranged such that the rails flush with the space inside surface of the Untersparrendämmplatten so that the rails and the space inside surface of the Untersparzendämmplatten form the support surface for fire protection panels or panels. Alternatively, the opposite recesses for receiving the rails are recessed, so that the bearing surface of the fire protection panels or disguising is the space inside surface of the Untersparzendämmplatten. It is also contemplated that no opposite recess for the space inside surface of the rails is formed on the space inside surface of Untersparrendämmplatten so that the rails (alone) form the support surface for fire protection panels or panels.

The rails for attaching the Untersparrendämmplatten to rafters or ceiling pliers on the one hand and fire protection boards or clothing on the other hand can be designed as U-profile strips, L-profile strips, T-profile strips, smooth with any stiffening profiles or smooth without profile in their webs ,

The profile rails for attaching fire protection panels or a cladding on the interior side of the Untersparrendämmplatten may be made of metal, plastic or any other suitable material for this application.

It is advantageous to prefabricate into the profiled rails a continuous, or only in the area of holes for fastening means an opposite profiling according to the size and shape of a head (eg., Screw head) and provide prefabricated holes for the screw, whereby a flat support of the Fire protection panels or cladding is guaranteed on the rails and the rails must not be pre-drilled when screwing to rafters or ceiling pliers.

This continuous or partially prefabricated in the area of the holes Schraubkopfprofilierung and stiffening profiling in the rails are optionally formed gegengleich equal to the space inside surface of Untersparzendämmplatten.

To avoid thermal bridges by mounting screws to the rails, if they are made of metal, insulating plastic shims may be attached to the prefabricated holes for mounting screw. This function can also be taken over by a continuous, profiled and perforated plastic rail.

If the rail is designed such that it forms the bearing surface for the fire protection boards or clothing, a coating on the interior surface or plate-side surface of the rails can be applied to sound optimization.

Furthermore, the profile rail can be provided with a fire-retardant (for example, foaming-up) coating on its interior surface.

The space inside surface of Untersparrendämmplatten can also be designed such that horizontally extending grooves for receiving mounting slats and horizontally extending slots (slot-like grooves) for receiving the legs of rails in the central grid spacing of 50 and / or 100 and / or 200 and / or 400mm are formed.

The sealing of the insulating surface can be made by masking the abutting edges of adjacent Untersparzendämmplatten by means of adhesive or sealing tape.

It is very advantageous if the masking and / or sealing of the horizontal and vertical abutting edges adjoin one another Untersparrendämmplatten is carried out on a continuous, plane adhesive plane or sealing level.

Since in the Untersparrendämmplatte - in the use position - horizontally extending grooves for receiving mounting slats, four-sided rails and / or horizontally extending slots in the position of use are provided for receiving rails, the masking and / or sealing the vertical abutting edges of adjacent Untersparzendämmplatten sometimes designed difficult. In the embodiment with grooves for receiving mounting slats or (square) rails there is a risk that the vertically extending in the use position adhesive or sealing tape on the panel joints in the corners at the bottom of the groove is not completely flush bonded in the edges. Leakage of the insulating surface, water vapor convection and the associated formation of moisture by outflowing, humid room air and condensation of water vapor in the dew point range would be the result. In the version with horizontally extending slots for receiving rails a sealing of the vertical abutting edges of adjacent Untersparzendämmplatten means of adhesive or sealing tape can not be produced without effort.

In this context, according to the invention can be provided in one embodiment that recesses are provided on both vertical and two horizontal abutting edges of Untersparrendämmplatten, at least the height of the groove for receiving mounting slats, four-sided rails or the height of slots for receiving the legs of rails and half the width of the adhesive or sealing tapes to be provided corresponds, whereby horizontally and vertically a continuous, planar plane for masking the abutting edges of adjacent Untersparzendämmplatten is formed by means of adhesive or sealing tape.

In the horizontal abutting edge region, this groove-shaped recess for masking the abutting edges of adjoining Untersparzendämmplatten be dimensioned such that this Stoßkantennut corresponds in its entire width and height of a groove for receiving mounting slats as described above or square rails and serves to accommodate them. To the Side surfaces of this horizontal Stoßkantennut, elastic moldings for central positioning and clamping fixing of mounting slats or four-sided rails can be formed as previously described. The elastic projections can optionally also be formed only on one side surface of the abutting edge groove.

The sealing in the region of the tongue and groove formation in the horizontal and vertical abutting edge region of Untersparrendämmplatten is inventively achieved in an exemplary embodiment in that the spring is made narrower than the inner dimension of the side surfaces of the groove. It is preferred if on the spring on the rising surfaces on both sides parallel and transverse to the spring extending sealing lips are formed. The spring with the sealing lips formed on both sides on the surfaces is dimensioned larger than the internal dimension of the side surfaces of the groove, so that the spring with the sealing lips formed thereon can be inserted into the groove by clamping. Due to the lower surface of the sealing lips and the resulting reduced friction compared to a conventional, full-surface clamping, one or two-fold tongue and groove formation, the Untersparzendämmplatten in this embodiment, the invention in the abutting edge region during assembly with substantially low resistance inserted into one another.

The parallel and transverse to the side surfaces of the spring extending sealing lips have the advantage of forming a plurality of sealing chambers. If sealing lips are partially damaged prior to collapsing adjacent Untersparrendämmplatten and thus the sealing function on a sealing chamber no longer be given, the sealing function of adjacent sealing chambers is maintained and thus the overall tightness in the abutting edge region of Untersparrendämmplatten ensured.

The sealing in the region of the tongue and groove formation in the horizontal and vertical abutting edge region of Untersparrendämmplatten can according to the invention, for example, be achieved in that the width of the spring is smaller than the width of the inner dimension of the groove. At the side surfaces of the groove to the bottom of the groove, a taper of the groove is formed, which is narrower than the width of the spring. In this taper of the groove, the spring is inserted by clamping when inserted into the groove. This rejuvenation can be on one or both Side surfaces of the groove may be provided.

According to the invention, this form of sealing can also be embodied, for example, such that the widening of the tongue towards its root has a widening that exceeds the inner dimension of the groove, so that the groove can be slid onto the spring in a clamping manner. This broadening in the region of the root of the spring can be formed on one or both sides of the spring.

This sealing variant can also be made in combination, so that a taper of the groove to its base and a broadening of the spring are formed to its root.

A sealing of the Untersparrendämmplatten in the abutting edge region can also be prepared according to the invention by the fact that in the spring one or more substantially parallel to their upstanding side surfaces extending / e / s slot / e is / are formed, which / r over any range of the height of the spring or extends into the region of the Untersparrendämmkörpers inside. The spring is wider than the groove. Upon insertion of the spring into the groove, the parts separated by the slit (s) of the spring are resiliently pressed against the lateral surfaces of the groove, whereby an elastic, reliable sealing of the tongue and groove joint can be produced. This elastic compression of the slotted spring can also be brought about and / or reinforced by tapering on the upstanding side surfaces at the bottom of the groove.

It is advantageous if the tongue and groove connection with slotted spring is substantially V-shaped. By this V-shaped configuration, the spring can be inserted over a large area without frictional resistance in the groove. Only in the last portion of the insertion of the spring into the groove, the clamping of the elastic, separated by the / slit / e parts of the spring is effective, whereby the side surfaces of the spring are pressed against the side surfaces of the groove, which towards its bottom to the Width or portions of the width of the slot in the spring is narrower.

This form of sealing can also be designed as a combined, parallel and V-shaped, opposite groove and slotted spring connection be.

The sealing in the abutting edge region of adjoining Untersparrendämmplatten can be made according to the invention also using elastic sealing strips. The elastic sealing bands may be attached to the horizontal and vertical abutting edges of the Untersparrendämmplatten in the position of use. But the elastic sealing bands can also be applied to the horizontal and vertical base of the groove or on the horizontal and vertical faces of the spring.

The sealing in the abutting edge region of adjoining Untersparrendämmplatten can also be carried out according to the invention by means of gluing. The bonding can be performed on the horizontal and vertical abutting edges of the sub-rafter insulation panels. But the bonding can also be done on the horizontal and vertical base of the groove and on the adjacent horizontal and vertical faces of the spring. The bonding can be carried out by adhesive application or by means of a double-sided adhesive tape.

According to the invention, the sealing in T- or Kreuzstoßkantenbereich the tongue and groove molding is achieved, for example, that at the bottom of the horizontal groove and on the horizontal end face of the vertical spring in parallel over portions extending from the bottom of the horizontal groove in the horizontal surface of the vertical spring and across the entire width of the horizontal groove and across the entire horizontal width of the vertical spring and at the bottom of the vertical groove and on the vertical face of the horizontal spring parallel over portions extending from the bottom of the vertical groove into the vertical surface of the horizontal spring and transverse to the entire width of the vertical groove and across the entire vertical width of the horizontal spring extending, one or more sealing lips or sealing wedges are formed. When inserting the adjacent Untersparrendämmplatten the end faces of the horizontal and vertical spring are pressed against the sealing lips or sealing wedges. The compression of the sealing lips or sealing wedges causes the sealing in T- or Kreuzstoßkantenbereich the tongue and groove shaping, even with slotted spring.

According to the invention, a surface heating / cooling on the interior side of Untersparrendämmplatten effected by the fact that on the space inside surface of the Untersparzendämmplatte recesses for receiving heating pipes / cooling tubes are formed. The recesses for receiving heating pipes / cooling pipes can also be subsequently formed in the space inside surface of Untersparrendämmplatten. The recesses for receiving heating pipes / cooling pipes on the space inside surface of the Untersparrendämmplatte can be arranged horizontally and / or vertically extending. To optimize the heating / cooling may parallel and / or transverse to the heating pipes / cooling tubes extending Wärmeleitbleche / Kühlleitbleche or Wärmeleitfolien / Kühlleitfolien be arranged to transfer heat to or from the interior space lining of Untersparrendämmplatten (eg fire protection boards, plasters o. Ä.) To increase. Wärmeleitbleche- or - foils / Kühlleitbleche or foils may optionally extend only over parts of the space inside surface of Untersparzendämmplatten so that on the not covered by Wärmeleitblechen or -folien / Kühlleitblechen or foils space inside surface of Untersparzendämmplatten sufficient diffusion is ensured.

The recesses for receiving heating pipes / cooling pipes on the space inside surface of Untersparrendämmplatte can be designed such that the heating pipes / cooling pipes flush with the space inside surface of the Untersparzendämmplatte or project the heating pipes / cooling pipes in partial areas on the space inside surface of the Untersparrendämmplatte to when applying a good heat-conducting / temperature-conductive plaster direct heat transfer from the heating tube / cooling tube to or from the plaster to increase by the enlarged surface of the heating tube / cooling tube directly in the plaster. Also in over the space inside surface of Untersparzendämmplatten protruding heating pipes / cooling tubes can be arranged to optimize the heating / cooling power parallel and / or transverse to the heating pipes / cooling tubes extending Wärmeleitbleche / Kühlleitbleche or Wärmeleitfolien / Kühlleitfolien to the transfer of heat to or from to increase the plaster. The projecting beyond the space inside surface of Untersparzendämmplatten heating pipes / cooling tubes can be attached by gluing or staples. The distances of the recesses for receiving heating pipes / cooling tubes can be adapted to the required heating / cooling capacity. The deflection of the heating tubes / cooling tubes can be formed in the space inside surface of Untersparrendämmplatte and / or done in remote areas at the abutting edges.

It is advantageous to provide horizontally and vertically running, numbered cutting marks on the space inside surface and / or the space outside surface of Untersparrendämmplatten, z. B. mold.
