Description

Insulation element and building wall

The invention relates to an insulating element made of mineral fibers, in particular stone wool and / or glass wool, in the form of insulating material sheets, insulating boards, insulating felts or the like, for installation between two building components arranged at a distance from one another, namely profiles in stud walls or mounting walls and / or facing shells and for soundproofing. and / or thermal insulation of ceilings and walls and similar parts of buildings, consisting of a mineral fiber body with two large, preferably spaced and parallel to each other surfaces and side surfaces connecting them. Furthermore, the invention relates to a building wall with a supporting frame, consisting of at least two, preferably vertically aligned stands arranged at a distance from one another, in particular in the form of U, W, Ω or C-shaped profiles made of metal, preferably at least one-sided cladding in the form of plasterboard and / or gypsum fiber boards, and thermal and / or acoustic insulation made of insulation elements.

Assembly walls usually have a support structure made of sheet metal profiles, which is usually clad on both sides with plasterboard or gypsum fiber boards. In so-called facing shells, only the visible side, e.g. the side facing the room is clothed.

The so-called stands are placed in horizontal U-shaped profiles that are attached to the floor and ceiling or other abutments. The suitable sheet metal profiles are also U-shaped, but the two legs are bent at right angles. Through a suitable profiling of the back and the two legs, these profiles are torsion-resistant despite relatively small sheet thicknesses and can absorb high lateral forces. The stand profiles are generally referred to as C profiles. The width of the support structures reaches approx. 50 to approx. 150 mm.

After setting up the support structure, one wall side is first provided with cladding panels. The clothing panels usually consist of Plasterboard, profiled sheets or similar materials and are attached to the support structure with the help of self-drilling and self-tapping screws, which are arranged at regular intervals of approx. 25 to approx. 35 cm. The vertical joints between the panels must be on one leg of the vertical C-profiles in order to avoid later crack formation. The rows of screws on each plate are staggered to achieve optimal stiffening. In this way, the C-profiles, which are initially loosely set in the U-profiles, are aligned with the dimensions of the cladding panels and fixed accordingly.

Mineral wool insulation panels or felts are now clamped into the open spaces on one side between the C-pillars. The minimum thickness of the insulation is approx. 4 cm. For this purpose, the insulation materials are pushed into the C-profiles from the side. This process presents some difficulties, since the insulation material has to be guided past the sharp-edged, approximately 5 to 10 mm wide, mutually directed bevels of the two legs. At the same time, the approx. 10 - 20 mm screws protruding into the cavity of the C-profiles form essential obstacles on which the insulation material gets caught.

In order to be able to pinch or impale the insulation material at all, extremely compressible insulation materials that are naturally not very dimensionally stable are often used. Nevertheless, it is usually not possible to completely fill the cavity according to the thickness of the insulation material. The resulting cavities generally have an impact on sound and heat insulation and, in the event of fire, on the fire resistance of the structure.

On the opposite side of the cavity, the insulation material is pushed along the relatively smooth back of the C-profile and clamped between the two abutments. Given the low stiffness of the insulating material, it slips out of the cavity and then prevents the cladding panels from being unscrewed. The insulation material can also slip easily because its thickness is regularly less than the depth of the wall cavities. If the insulation material slips off in the ceiling area, there are sound and heat bridges as well as areas with reduced fire resistance, so the wall insulation is poor here.

The same applies to facing shells if they are not arranged close to a counter surface.

The incomplete filling of the C-profiles in connection with slipped insulation materials and air gaps between the insulation material and clothing also allows cold outside air to penetrate through open walls, as can often be found in attics. In these cases, the cold air can even flow from the sockets into the heated rooms and cause significant energy losses.

In order to significantly improve the usage properties of the wall and avoid defects with the same material used for the support structures, the specified cavities should be completely filled with insulation materials.

The invention is based on the task of improving an insulating material and a building wall of the generic type in such a way that the installation of insulating materials in assembly walls as well as in facing shells or in the internal insulation of ceilings and walls is facilitated and in terms of heat and Soundproofing is improved, the insulation materials being applied so as to fill the cavity in such a way that they can be adhered to in a simple manner, in particular on the inner walls of the surface parts surrounding the cavity.

The solution to this problem provides for an insulation element according to the invention that in the area of at least one narrow side there is a section designed as a profiling of the profile and serving as a filling profile and which can be inserted into the profile in a form-fitting manner. On the part of the building wall, according to the invention, in order to solve the task, it is provided that the insulation element in the area of at least one narrow side NEN according to a profiling of the profile, serving as a filler section, which can be inserted in a positive manner in the profile.

With an insulation element according to the invention, there is the possibility of substantially agreeing the installation work of such insulation element between spaced-apart building components, so that such installation work can be carried out in a simple manner by one person. For example, insulation elements according to the invention can be installed in a building wall designed according to the invention. For this purpose, it is provided that, in a first step, a section which is designed in accordance with the profile of the profile and serves as a filling profile is arranged in the profile before the further insulation is subsequently installed. The section serving as a filling profile can be installed at the factory or on site. Depending on the bulk density of the section and thus in particular on its compressibility, the section can be inserted in the longitudinal direction before the profiles are set up or pressed in transversely to the longitudinal direction of the profiles after the profiles have been set up.

Further features and preferred developments of the invention result from the subclaims and the following description.

The invention has the advantage that the cavities of the profiles are initially completely filled with sections designed as filling profiles, preferably made of bound mineral fibers. The section can be easily inserted into the cavity of the profile and is designed in accordance with the internal cross section of the profile, so that the section is in full contact with both the inner surfaces of the profile legs and the inner surface of the profile web and completely and approximately fills the internal cross section of the profile cuts flush with the edges of the profile.

At least one of the side surfaces of the section can be coated with an adhesive slide, so that the section is fixed in the profile. The adhesive surfaces of the sections can also be directed outwards. Several outer surfaces of the section can also be equipped in this way. The mineral wool insulation boards or insulation felts can now be easily inserted between the free side surface of the section and the web of the opposite profile into the cavity between the adjacent profiles and thereby clamped. To secure the position, the insulation panels of the insulation felts can be equipped with a layer of adhesive slide on one or both side surfaces.

Suitable adhesive tabs include Melt adhesives (hot melt adhesives) in question, which consist for example of thermoplastic rubber. These so-called pressure-sensitive hotmelt adhesives are sprayed, poured or extruded onto the side surfaces of the insulation boards or insulation felts at an elevated temperature and then covered with plastic films in order to maintain their adhesiveness. Likewise, the outer back of each adjacent profile can also be coated with an adhesive slide for connection to the insulation board or the insulation felt.

Another design option is to weld or glue composite materials made of glass or plastic fibers or metal foils with foils made of thermoplastic plastics onto the corresponding surface. The high thermal conductivity of the metal foils is no additional disadvantage in the assembly walls because of the thermal bridges already present there, but the foils are preferably only applied partially, in particular parallel to the central axis of the side surfaces, to the insulating materials.

With stronger insulation boards, coatings, e.g. made of cement or plastic mortar, water glass paints, silica sol etc. be applied on which adhesive tapes adhere.

The invention can generally be implemented with sections of mineral wool or hard foam. According to a further feature of the invention, it is provided that the section is formed separately from an insulation board or insulation sheet. In principle, however, there is also the possibility that the section is part of an insulation board or insulation sheet, the former possibility of course being easier to handle.

It is further provided that the section can be connected to the insulation board or the insulation sheet, in particular can be glued and / or positively, preferably by means of a tongue and groove configuration. As a result, a secure connection of the section with the insulation board or

Insulation sheeting ensures that thermal bridges or discontinuities in the thermal insulation are prevented.

The section preferably has a bulk density of up to 200 kg / m ³ , so that the section stiffens the profile. In principle, the sections can also have bulk densities of less than 55 kg / m ³ , so that their compressibility makes it easy to insert them into the profiles between the legs. With bulk densities between 100 and 200 kg / m ³ , the section is suitable for stiffening flexible stand profiles from thin metal sheets.

In addition, it can be provided that the section has, at least on one side, a bending-resistant reinforcement, for example a strip of plasterboard, gypsum fibreboard, wood, plastics or metal, in particular at lower bulk densities of, for example, <55 kg / m ³ . This configuration combines the advantages of a section with a high bulk density with the advantages of a low bulk density, namely the flexibility and compressibility, so that a section designed in this way can not only be inserted into a profile in a simple manner, but also stiffen a flexible stand profile due to the bending-resistant reinforcement can.

It is provided according to a further feature of the invention that in this embodiment the strip is arranged at right angles to the legs of the profile or parallel to a web connecting the legs of the profile. The strip is preferably arranged behind a flange of the profile. net to fix it in place. On the other hand, when using the insulation elements according to the invention, flanges as a stiffening means of the profile can be dispensed with. When sections are used, box profiles are created which are acoustically effective on the one hand and on the other hand increase the stiffness of the profile, in particular of a stand profile.

In order to improve the installability of the section, it is provided that the section, in particular with a bulk density of 100 to 200 kg / m ³ , has at least one, preferably two or more incisions and / or recesses in at least one, preferably in both side faces, which are preferably parallel to the surface normal of the side surfaces. These incisions and / or recesses allow a certain compressibility of the section in order to simplify installation in the profile, in particular if the profile has beads or the like in the region of the legs.

Alternatively, it can be provided that the section, in particular with a bulk density of 100 to 200 kg / m ³ , is made elastic in the area of at least one, preferably both, side surfaces, in particular by mechanical flexing with the associated dissolution of the fiber composite. This embodiment also serves to increase the compressibility of the section, at least in the area of a side face, in order to simplify the installation of the section in a profile.

The above-mentioned features and advantages of the insulating element or its further developments also apply to the design of the building wall according to the invention. In this regard, reference is made to the above advantages with regard to the subordinate claims to the building wall according to the invention.

Cross section and

Fig. 9 shows a connection insulation element for the sections of Figures 7 and 8 in cross section.

A stand wall 1 is shown in FIG. The stud wall 1 extends between a ceiling D and a floor B and essentially consists of two profiles 2 and clothing elements 4 arranged on both sides of the profiles 2. The clothing elements 4 are in particular gypsum plasterboard and / or gypsum fiber boards, which are preferred have such stud walls 1 processed. The profiles 2, which are made of sheet steel or light metal, have two legs 5 and a web 6 connecting the legs 5, the legs 5 being aligned parallel to one another. The profiles 5 are attached to the ceiling D or floor B with screws 3.

The clothing elements 4 are also fastened to the profiles 2 with screws 3, for example, shown in FIGS. 4 and 5, which pass through the clothing elements 4 and a leg 5 of the profile 2.

A sound insulation S, which consists of profiled mineral fiber strips, is arranged between the ceiling D and the floor B and the profiles 2.

The profiles 2 have a web 6 which is profiled for reasons of stability. According to the profiling, the profile 2 arranged on the ceiling D can be referred to as a W profile. In its central region, the web 6 also has a U-shaped bead 7 which, for example, can also be designed to accommodate the screws 3 with a large number of holes. The profile 2 arranged in the area of the bottom B has a web 6 which is oriented at right angles to the legs 5 and has two beads 7 on both sides of a central area 8 in which a row of holes for receiving the screws 3 is arranged. The beads 7 are aligned in the direction of the legs 5.

The mineral fiber strips of the sound insulation S are designed in accordance with the profile of the web 6 of the profiles 2, so that, for example, the mineral fiber strip of the sound insulation S has two projections in the region of the base B corresponding to the configuration of the beads 7.

Between the profiles 2, an insulating element 9 is arranged, which consists of several insulating boards made of mineral fibers, for example rock wool. The insulation element 9 extends from the web 6 of the profile 2 arranged on the floor B to the web 6 of the profile 2 arranged on the ceiling D. Accordingly, the insulation element 9 is inserted between the legs 5 of the profiles 2. The insulation element 9 has a material thickness which essentially corresponds to the length of the web 6 and thus to the distance between the two legs 5 of a profile 2. A slight excess of the material thickness of the insulation board 8 compared to this distance between the legs 5 of the profile 2 is in this case harmless and generally desirable in order to fill the cavity between two spaced-apart clothing elements 4 as completely as possible with insulation material.

Profiles 2 are set as stands in the profiles 2 fastened at the bottom and decks, these profiles 2 being connected to the profiles 2 fastened to the floor B or the ceiling D in a force-locking or positive manner, for example also screwed or riveted.

When creating a stud wall 1, the profiles 2 are arranged on the top and bottom sides in a first step and dowelled with screws 3. Subsequently, the profiles 2 designed as stands are set at a distance from one another in the profiles 2 arranged on the floor and deek side and screwed to them. The distance between two adjacent profiles 2 corresponds essentially to the length or width of insulation boards to be installed subsequently.

In the next step, the frame created from the profiles 2 arranged as stands and the floor and ceiling profiles 2 is provided on one side with clothing elements 4, the clothing elements 4 being mounted with screws 3 on the profiles 2 and optionally also on the floor and ceiling side Profiles 2 are screwed.

In Figures 2 to 5 different profiles 2 are shown, which can be used as stand profiles. FIG. 2 shows the section of a stud wall 1 with two spaced-apart profiles 2, which in turn have two legs 5 and a web 6 connecting the legs 5, the two profiles 2 being arranged in the same direction between the clothing elements 4. It can be seen that the profiles 2 two on the free ends of the legs 5 bends 10 aligned to one another. The profile space existing between the bends 10 and the web 6 on the one hand and the two legs 5 on the other hand is filled with a section 11 as a filling profile. This section 11 is described in more detail below.

An insulation element 12 is arranged between the profile 2 facing a wall W and the wall W, which in turn is designed in accordance with the profile of the web 6. The web 6 of the profile 2 is designed in accordance with the web 6 of the profile 2 fastened to the ceiling D according to FIG. 1, with the difference that the bead 7 in the profile 2 shown in FIG. 2 is not U-shaped but V-shaped in cross section is.

Another embodiment of profiles 2 is shown in Figure 3. The profile 2 shown on the left in FIG. 3 is C-shaped and has a wide bead 7 in the region of its web 6. Such a profile 2 is also referred to as a CW profile.

The profile 2 shown on the right in FIG. 3 consists of expanded metal and has a web 6 with a semicircular bead 7.

Figures 4 and 5 show profiles 2, as are known for example from DE 199 50 890 C1. These profiles 2 are referred to as Ω-shaped stand profiles and have a web 6 in the form of an arcuate section and profiled legs 5. In addition, these profiles 2 have L-shaped bends 10 at the free ends of the webs 5.

The exemplary embodiment according to FIG. 4 is characterized in that the web 6 additionally has a U-shaped bead 7 and the legs 5 are profiled in a zigzag shape. In contrast, the legs 5 are profiled in a wavy shape in the exemplary embodiment according to FIG.

FIGS. 6 to 9 show the sections 11 which can be used in the profile space of the profiles 2. The sections 11 consist of mineral fibers and ben a bulk density of about 100 kg / m ³ , so that the sections 11 are able to stiffen flexible profiles 2.

The sections 11 are designed in accordance with the profiling of the profile 2 and serve as a filling profile which can be inserted in the profile 2 in a form-fitting manner. For example, the section 11 shown in FIG. 6 has a semicircular recess 13 which is designed in accordance with a bead 7 according to the right profile 2 in FIG. 3. The surface 14 opposite the recess 13 can be curved in accordance with the upper section of FIG. 6 or straight in accordance with the lower section in FIG. 6, this area coming into contact with the insulating element 9 in the stud wall 1.

A layer 16 of an adhesive adhesive that can be activated during installation is arranged on each of the two narrow sides 15 of section 11. The adhesive slide is activated by removing a cover 17 arranged on the layer 16, for example a film. The adhesive slide serves to glue the section 11 in the profile 2, namely on the legs 5.

FIG. 7 shows a section 11 for use in an Ω profile 2, a side surface 15 having two mutually spaced, parallel to the surface normal of the side surface 15, cross-sectionally rectangular grooves 18 and a cut 19 arranged in between. The grooves 18 and the notch 19 serve to increase the compressibility and flexibility of the section 11 in order to facilitate the installation of the section 11 in the profile 2. Otherwise, section 11 corresponds in its cross-sectional shape to section 11 according to FIG. 6. In addition, section 11 according to FIG. 7 has bevels 20 in the transition region between surface 14 and narrow sides 15. As shown in FIG. 8, these bevels serve to adapt the section 11 to the bends 10 of the profile 2.

For the connection of the profile 2 according to FIG. 8 to a wall W, the insulating element 12 shown in FIG. 9 is provided, which has a straight surface 21 lying against the wall W and a profile 22 in the area of the surface 21 has opposite surface, which profiling 22 corresponds to the bead 7 of the profile 2.

It can be seen that the insulation element 12 has a width b that is greater than the width of the profile 2. Overall, the width b of the insulation element 12 is the sum of the width of the profile 2 plus the material thickness of the clothing elements arranged on both sides of the profile 2 4. The insulation element 12 also consists of a slightly compressible mineral fiber insulation material.
