Description

Extension profile to increase the height of a support

The invention relates to an extension profile to increase, if necessary, the height of the supports of a supporting structure, in particular of the winches of a roof framework or of the beams of a flat roof, depending on the thickness of the respective thermal insulating material used, with an essentially L-shaped cross section

or essentially U-shaped, in which a mounting core (2) provided for fixing on a support and a covering flange (4) are provided, which at least partially grasps this support at a corresponding distance at least approximately to the application of the extension profile (1) with respect to the supporting structure, this mounting core (2) and the covering flange (4) being arranged at an angle at least approximately straight.

A similar profile is previously known from DE 296 08 384 U1. In this case it is a so-called roof finishing element in an embodiment of light construction, with which the substructure, for example, of a suspended ceiling in the framework of a ceiling finish must be developed.

Not for this purpose, but in general, profiles with an L-shaped cross-section that are provided with a plurality of longitudinal holes arranged transversely or longitudinally for fixing purposes, as known for example from US 3,250,051 for decades , belong to the state of the art.

Within the framework of the current modern construction activity it is essential to provide the construction of a roof of single-family houses and neighborhood houses of a corresponding thermal insulation. For this, in the planning phase, the corresponding need for thermal insulation of the corresponding work is determined, a thermal insulating material is selected and the necessary thickness of the thermal insulating material is calculated with usual calculation programs. In this case the thickness of the thermal insulating material depends both on the roof construction, as on the planned use of the building and a complete series of other circumstances. Finally, the desire of the manufacturer of the thermal insulating material to be used must not be taken into account.

But as a result in any case the type of thermal insulating material to be used establishes in particular the thickness of the respective thermal insulating material to be used. Usually the thermal insulating material is then carried in the constitution of the roof construction to the area between the cabrio or the beam and is terminated with a vapor barrier sheet nailed on the underside of the beams or fixed in another way or another membrane.

In the framework of the projection and planning of work, in this case it should be taken into account that, consequently, the cross-section of the beams or beams used are not only selected according to the corresponding cover load, but also depending on the thickness of the thermal insulating material necessary. But this is an absurd prescription in itself since the beams or rafters are the most valuable and therefore more expensive component in the construction of a roof framework, so that due to the costs the dimensioning of the roof does not necessarily seem reasonable. bearing structure depending on the thickness of the thermal insulating material.

Another problem is that again, depending on the weight of the roof construction, the remaining bearing construction of the building must be selected, for example the dimensioning of the bearing walls. The expansion of the roof support structure is then linked to considerable derivative costs throughout the building.

The invention therefore has the objective of creating a versatile device that allows us to select the dimensioning of the supporting structure, in particular of a roof framework, almost independently of the dimensioning, in particular the thickness, of the thermal insulating material.

This objective is achieved by an extension profile according to the main claim. Advantageous configurations of the solution according to the invention are deduced from the characteristics of dependent claims 2 to 9.

The extension profile according to the invention essentially has an L-shaped cross-section, complementing a mounting core and a cladding flange, which enclose with each other at least approximately a right angle, to the L-shaped cross-section in question. In this case, the extension profile in question joins the supports of a supporting structure through the mounting core, so that the cladding flange secures these supports at least in sections, spaced apart, preferably below the supports. The cladding flanges arranged at distances corresponding to distances from the supports therefore result in a fixing plane arranged below the lower edge of the supports. The assembly souls themselves represent in this case a widening of the supports. As a result, the reception space is then extended for eventual thermal insulation between a lower ceiling surface and a fixing plane, for an intermediate space that originates in this way, for example, in the ceiling of a room, by fixing the extension profiles in the supporting structure at least in the distance between the cladding flange and the lower edge of the supporting structure. Thus it is possible to introduce a thermal insulation of greater thickness in the reception space defined above and increased according to the invention by using the

extension profile Additionally, the cladding flange is provided with a fixing device to establish at least provisionally after the assembly of the thermal insulation a steam blocking sheet that ends on the side of the room the thermal insulation or another membrane.

The cladding flange is provided with a trough profile open downward on the side away from the mounting core. In an alternative configuration on the corresponding edge of the cladding flange, a corrugated profile is formed instead of the trough profile, which enters into active connection with a corresponding clamping profile for fixing the vapor barrier sheet or other membrane, or instead of the corrugated or trough profile, a corresponding longitudinal edge of the open lining flange is provided in the direction of the mounting core, into which an embedded profile that can be closed again with a plastic intercalating plug is fitted. a vapor barrier sheet or other membrane.

As a result, this extension profile then satisfies, together with the function of a simplified adaptation of the mounting space to thermal insulation, also the function of a mounting aid for fixing the vapor barrier sheet or other membrane.

A first mounting aid for the thermal insulation to be introduced in this intermediate space is produced by the first configuration with the shaped trough profile, since the transition zone between the mounting core and the cladding flange is not approximately at right angles, rather, it is provided with a bulge that protrudes during the intended assembly approximately above the fixing plane. This results in a first fixation of the thermal insulation to be introduced in the intermediate space.

Another advantage of bulging and consequently of giving up the right angle between the mounting core and cladding flange is that at this point a cutting edge is avoided and therefore machining of the cladding profiles is possible with a risk of injury clearly reduced. The use of transitions and sharp edges should also be avoided by looking at the sensitive thermal insulating material used.

However, in an advantageous configuration, the trough profile in question can also be used to introduce the vapor barrier sheet used for closing on the side of the thermal insulation room or other membrane. To this end, a profile of the known fence can be introduced into the trough profile by inserting the vapor barrier sheet. This results in a first tightening of the vapor barrier sheet. The cladding flange thus serves firstly for the simple and reasonable fixing of the vapor barrier sheet or other membrane below the thermal insulation introduced in the intermediate space between winches and the extension profile according to the invention.

The mounting core can be screwed easily with the supporting structure, in particular beams or rafters. For this, a plurality of mounting holes are already integrated in the mounting core, the mounting holes being preferably arranged at a different height, in order to be able to fix the mounting core without problems at different height in the corresponding support.

In this respect it has proved advantageous that in addition to the mounting holes themselves, oblong holes are provided that are distributed at least almost vertically with respect to the longitudinal extension of the mounting core, distributed over the length of the mounting core. These oblong holes serve for a first fixation of the extension profile on the supports of the supporting structure. After the extension profile is connected to the supports with the first fixation, the exact height can then be adjusted and the final fixation can be made with respect to the roof wrap or the supporting structure through the mounting holes described above. .

In the newly advantageous configuration of the solution according to the invention, adjustment tabs are integrated additionally or alternatively in the mounting core, so that these are completely clipped except for a fixing edge.

These adjustment tabs can be chamfered around the folding edge, so that as a consequence they cause a widening of the mounting core and therefore can be used to widen if necessary the distance between the covering flange and the lower edge of the bearing structure or roof framework. In this case, the extension profile is connected to the corresponding roof or supporting structure by means of additional mounting holes in the adjustment tabs.

The mounting of the thermal insulation in the intermediate zone between the roof wrap or the supporting structure and the extension profile according to the invention can be further simplified because in a clamping section of the mounting core directed towards the cladding flange, the mounting souls that can be folded out of the plane of the mounting core, producing the projections thus generated an interlocking with the adjacent thermal insulating material. Together with the first clamping by the bulges already described in the transition zone between the mounting core and the cladding flange, this interlocking with the clamping souls represents a real and effective support for the thermal insulating material introduced. This is in particular then an effective mounting aid if, after the complete introduction of the thermal insulating material, the vapor barrier sheet must already be mounted.

mentioned. Then it is no longer necessary to fasten the introduced thermal insulating material in a complicated way, while in another place the vapor barrier sheet or another membrane is fixed. The “third hand” that is frequently missing in this context is not needed. Instead, the support is placed by means of the aforementioned holding soul.

The clamping souls in question are elongated in this respect on the folding edge of elastic shape in the mounting core. It has been shown that due to the consequently elastic support of the thermal insulating material, instead of a directly adjacent support of the thermal insulating material in the extension profile, it reduces at least the transfer of a noise propagated by solid structures, when it does not even exclude it . The clamping souls therefore also represent a measure for the improvement of the soundproofing or spatial acoustics of the thermally insulated space correspondingly.

The fixing of the thermal insulating material by means of the clamping souls can be further improved because several clamping souls arranged in a declined manner in relation to each other are provided over the length of the mounting core.

The extension profile can be made of both plastic, for example PVC, and metal, for example sheet steel.

In this case, the extension profile is manufactured, respectively, as a genre with the tronzable meter with a preferred dimension of 2,500 - 4,000 mm.

The extension profile according to the invention is explained in more detail by an embodiment shown only schematically in the drawing.

Figure 1 shows a configuration of an extension profile 1 in a perspective view.

The extension profile 1 is provided with a mounting core 2 in which a covering flange 4 is articulated through a bulge 3. The mounting core 2 is provided with a multiplicity of mounting holes 5 arranged spaced apart from each other. and displaced in height from each other. As can be seen from the unit hole pattern, the mounting holes 5 can be practiced by a simple punching process at an elevation in the mounting core 2. The oblong holes 6, which run vertically with respect to the longitudinal extension of the core of assembly 2, also provided in a distributed and spaced manner on the

length of the mounting core 2. These oblong holes 6 serve for a first height-yet-adjustable assembly of the extension profile 1 in a bearing structure not shown in Figure 1.

As will be explained in detail below, the mounting core 2 is attached to a supporting structure, thus preferably to the winches or the beams of a roof wrap, so that the lining flange 4 grabs at least by sections below the bearing structure at a defined distance. The supporting structure complemented by the fixing of the mounting core 2 in the beams or the rafters 30 is therefore increased at least approximately in the width of the extension profile 1.

In addition, the lining flange 4 protruding on the mounting side of the mounting core 2 is complemented on the longitudinal side away from the mounting core 2 with a trough profile 7 open downwards. The trough profile 7 narrows in this case towards the open side, the outer edge 10 of the trough profile 7 provided on the outer side being provided with an additional fold 11 to avoid already a live edge termination of the lining flange 4.

According to the cross-sectional representation in FIG. 2, the open trough profile 7 can be advantageously used to fix, in the sense of a simple tightening fixation, a vapor barrier sheet 34 or another membrane at the height of the fixing plane 33 formed by the covering flanges 4 by simple tightening. For this, a frame profile 12 is introduced into the opening of the trough profile 7 by inserting the vapor barrier sheet or membrane not shown here and consequently a separable tightening fixation is created for the corresponding sheet or membrane.

An alternative fixing possibility is shown in figure 3. According to the representation in figure 3, a U-shaped elbow 13 can also be provided on the longitudinal side of the lining flange 4 away from the mounting core 2. In this case the open side of the U-shaped elbow 13 is directed towards the mounting core 2, while the edge side 13 away from the mounting core 2 is covered by a plastic profile that is provided with a semicircular profile 15 open downwards on the far side of the mounting core 2. The semicircular profile 15 can then also be closed with an appropriate plastic plug 16 interposing the vapor barrier sheet or membrane.

Figure 4 shows a possibility of fixing a new alternative for a similar membrane or a vapor barrier sheet 34.

According to the perspective representation in Figure 4, the longitudinal side of the cladding flange 4 away from the mounting core 2 is provided with a corrugated profile 17, which can be engaged in the intended manner according to Figure 6 with a clamping profile 20 , so that a vapor barrier sheet 34 or another membrane is again fixed by the clamping profile 20 at the lower edge of the cladding flange 4.

According to Figure 4, the embedded profile 14 differs in this representation from the previously described embodiments of a similar extension profile 1 not only by the fixing device for a vapor barrier sheet 34. According to Figure 4 the mounting core 2 it also presents in the area of the section 21 directed towards the cladding flange 4 additionally also holding souls 22 spaced apart from each other, which on the other hand are arranged displaced in height. The clamping souls 22 are punched in this case essentially according to the shape of an oblong hole 6, the abutment edge 23 of the clamping core 22 directed towards the covering flange 4 not being cut, but rather the clamping souls 22 they are slightly chamfered above this folding edge 23, so that they protrude in the direction of the thermal insulation 32 adjacent to the mounting core 2. This projection can be seen, for example, in the cross-sectional representation in Figure 5.

Another difference of the extension profile 1 shown in Figure 4 is that at the height of the fixing section 24 of the mounting core 2 disposed above the holding section 21, adjustment tabs 25 are additionally integrated. The adjustment tabs 25 are also provided in this case with mounting holes 5. The adjustment tabs 25 are essentially rectangular in shape, the adjustment tabs 25 being completely cut out except for a fixing edge 26 away from the covering flange 4. In case If necessary, the adjustment tabs 25 can be folded at least almost completely in the direction of the mounting side of the mounting core 2, so that according to the representation in figure 5, the recessed adjustment tabs 25 cause an increase in the height of the mounting core 2 at least in the area of the adjustment tabs 25. The embodiment with the adjustment tabs 25 can be covered by Next, a greater bandwidth of possible applications.

Naturally similar adjustment tabs 25 can also be used with the other possible embodiments of the extension profile shown in the drawing. Thus the representation shows in figure 6 an extension profile 1 according to the representation in figure 1, which is also provided with corresponding adjustment tabs 25. In this case the adjustment tabs 25 are already completely folded in the representation according to figure 6. The recessing of the adjustment tabs 25 can be carried out in place and with the simplest tools, thus by

example with a conventional combined plier.

With the detailed representation according to figure 7, it is shown as an extension profile 1 according to figure 1 or according to figure 6, it can be attached to the support of a supporting structure, thus in particular a roof beam. According to the perspective representation in Figure 7, the adjustment tab 25 is connected to the cabrio 30 by means of fixing screws 27.

According to the representation in Figure 7, therefore, an elevation of the winch 30 is achieved through the extension profile 1, the covering flanges 4 arranged below the winch 30 defining a fixing plane located below the winch 30.

The use of a similar fixing plane 33 is documented in Figure 9. According to this representation, firstly, the reception space 31 located between the winches 30 is enlarged according to the claim for thermal insulation 32. As a result, it can therefore be mounted accordingly. a thermal insulation 32 of greater thickness between the goats 30 not otherwise modified. In this case, the extension profile 1 according to the invention can also be used to compensate for possible level differences, conditioned by the assembly or conditioned due to the different thickness of the winches 30, between the winches 30.

As a result, the lining flanges 4 therefore form a fixing plane 33 drawn in strokes in Figure 8. In this fixing plane 33 a vapor barrier sheet 34 can then be fixed easily by inserting the frame profile 12 already mentioned above.

After the corresponding application of the vapor barrier sheet 34, in order to complete on the side of the room the thermal insulation 32, additionally the cladding flanges 4 can then be used to mount on them a metal or wood substructure 35, in which the respective interior space coating of plasterboard 36 or a panel covering can then be applied.

The extension profile 1 according to the invention can also be used advantageously for the constitution of a wall covering in the dry construction.

In fig. 10 shows a possible concrete conversion of this additional application. According to the cross-sectional representation, an extension profile 1 is chamfered according to Figures 4 and 6 above the clamping section 21 so that the extension profile 1 is together a U-profile whose parallel sides are formed by the fixing section 24 and cladding flange 4.

In this configuration the extension profile 1 can be used as a profile for an additional wrap according to fig. 11 in order to constitute an additional envelope. In this case, the lining flange 4 also serves here to fix a metal or wood substructure 35 in which the plasterboard plates 36 or other interior space covering can be mounted. Figures 10 and 11 therefore show a further application of the extension profile 1 according to the invention.

Previously, an extension profile 1 has therefore been described, with which the corresponding construction of the supporting structure can be extended without problems, on the one hand, so that the reception space 31 for thermal insulation 32 is increased, so that that the respective desired thermal insulation 32 can be introduced without problems in the respective desired thickness. After the introduction of the thermal insulation 32, it is then held first by the holding souls 22 in the intended position. Since the lining flanges 4 are provided in an advantageous configuration of corresponding fastening devices, a completion can be easily mounted and adjusted on the room side of the thermal insulation, for example, by a vapor barrier sheet 34. In particular, the use of simple tightening solutions makes it possible to achieve, after a first assembly, a rigid laying of the vapor barrier sheet 34 in the fixing plane 33 formed by the covering flanges 4. The fixing plane 33 formed by the flanges The coating 4 can then be used advantageously in a conventional manner in order to apply the respective desired roof covering below the now insulated thermal construction.

The extension profile 1 according to the invention therefore provides a measure to avoid unnecessary construction costs, as well as a considerable mounting aid in relation to the constitution of thermal insulating roof frames.
