Description

The invention relates to an insulating element made of mineral fibers, in particular Rock wool and / or glass wool, in the form of insulation sheets, insulation panels, Insulation felt or the like, especially for installation between two spaced-apart building components, such as rafters, Profiles in stud walls or assembly walls and / or facing shells as well for sound and / or thermal insulation of ceilings and walls and the like Building parts consisting of a mineral fiber body with two large ones in front preferably spaced and parallel surfaces and these connecting side surfaces. The invention further relates to a building wall with a support structure consisting of at least two spaced apart ordered, preferably vertically aligned stands, especially in Form of C-shaped profiles made of metal, at least one panel, preferred wise in the form of plasterboard and / or gypsum fiber boards, and a heat and / or sound insulation from insulation elements.

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

The so-called stands are placed in lying U-shaped profiles, which are attached to the floor and ceiling or other abutments. The suitable sheet metal profiles are also U-shaped, but the both legs are bent at right angles. With a suitable profile of the back and the two legs, these profiles are relatively low Sheet thicknesses are torsion-resistant and can absorb high lateral forces. The Stand profiles are generally referred to as C profiles. The width of the Support structures reach approx. 50 to approx. 150 mm.  

After setting up the support structure, one wall side with Be provided clothing panels. The clothing panels usually consist of Plasterboard, profiled sheets or similar materials and are made with the help of self-drilling and self-tapping screws at regular intervals from approx. 25 to approx. 35 cm are attached to the support structure. The Vertical joints between the panels must be vertical on one leg ten C-profiles to avoid later cracks. The rows of screws each plate are staggered to ensure optimal exit to achieve. The C profiles, initially loosely inserted in the U profiles aligned in this way to the dimensions of the clothing panels and fixed accordingly.

In the open spaces on one side between the C-pillars are now Mineral wool insulation boards or insulation felt. The minimum thickness of the Insulation material is approx. 4 cm. The insulation materials are from the side in the C-profiles inserted. This process presents some difficulties because the insulation material against the sharp-edged, about 5 to 10 mm wide, against mutually directed bevels of the two legs are passed got to. At the same time, the approx. 10-20 mm form into the cavity of the C-profiles protruding screws essential obstacles on which the insulation material hang remains.

In order to be able to pinch or impale the insulation material at all They like to be extremely compressible, but naturally they have little shape stable insulation materials used. Nevertheless, the hollow does not regularly succeed completely fill the space according to the thickness of the insulation material. The first voids generally affect sound and heat insulation and Fire on the fire resistance duration of the construction.

On the opposite side of the cavity, the insulation material on the relatively smooth back of the C-profile pushed along and between between the two abutments. With the low rigidity of the insulation  fabric slips out of the cavity and hinders it then unscrewing the clothing panels. The insulation can too easily slip because its thickness is regularly less than the depth of the wall cavities. If the insulation slips off in the ceiling area, there are sound and thermal bridges and areas with reduced fire resistance, the wall insulation is therefore poor here.

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

The incomplete filling of the C-profiles in connection with slipped insulation fabrics and air gaps between insulation and clothing also allow this Penetration of cold outside air through open walls, as is often the case in roofs are shot. In these cases, even the cold air from the plug Cans flow into the heated rooms and cause significant energy losses ken.

In order to use your own with the same use of material for the support structures should improve the wall significantly and avoid defects, the predetermined cavities are completely filled with insulation.

Such assembly walls are often retrofitted in buildings to the base large rooms in smaller rooms. Usually exists then a need to run power and / or data lines into the rooms. For this purpose, plastic cable ducts can be screwed onto the assembly walls or be glued in which the data and / or power lines can be inserted. For aesthetic reasons, this procedure is and / or office space less suitable.

The introduction of data and / or power lines is therefore already with the Er position of such assembly walls desired. These lines are often there Fitted together with the flexible insulation materials, but what the temporal  coordination of the work of the different trades required. in this connection there is often damage to the insulation materials when pressing in Cables.

The invention has for its object an insulation element and a Building wall of the generic type to improve that the Installation of energy and / or data lines in assembly walls as well as in Facing shells or with the interior insulation of ceilings and walls easier and is improved in terms of heat and sound insulation, the Insulation materials are filled so as to fill the cavity.

The solution to this problem is seen in an inventive Insulating element before that the insulating body is strip-shaped and in at least one surface and / or side surface at least one continuous, recess open to the surface or side surface as a guide channel for Da has ten and / or power lines.

On the part of the building wall is fiction to solve the task in accordance with that part of the insulation elements are strip-shaped are formed and have a recess which acts as a guide channel for data and / or power lines.

With an insulation element according to the invention there is the possibility of Installation work of such insulation elements between spaced buildings essential parts to be agreed and at the same time arrangements for the after to carry out sluggish laying of energy and / or data lines. Thus, NEN energy and / or data line after completion of the insulation in the Stand or assembly wall can be easily installed without the There is a risk, for example, that the insulation is damaged.

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

By arranging the insulation elements with the recesses in the C- Profiling the building wall is a clean management of the energy and / or data Cables possible in the vertical direction. The insulation elements can can also be arranged horizontally between two C-profiles and then border For example, on insulation panels that in the thermal and / or sound insulation serve the building wall. Thus, a complete heat and / or sound insulation with simultaneous arrangement of a guide channel for energy and / or data lines created. The energy and / or data line can consequently arranged in a horizontal and vertical direction the, so that for example a diagonal laying of energy and / or Da is avoided.

A solution that is favorable in terms of processing technology is to use the cables in the course of Bring in the creation of the building wall. Usually, however, many are energy ge and / or data lines only required after the building wall has been created Lich. In order to carry out subsequent installation work from the state of the art nik known cable pulling aids, for example with glass fiber rods, use To be able to, it has proven to be advantageous, the bulk density of the insulating materials elements at least in the area of the recess in order to be sufficient Achieving stability in particular the walls of the recess, the also serves to guide the cables that are inserted afterwards.

Such insulation elements are relatively rigid and can also in short or long sections are installed or built into the C-profiles.

Plastic conduits can be inserted into the recesses in the insulation elements be inserted as far as the wall construction is sufficiently dimensioned. In In this case, the data and / or energy can be installed later lower bulk densities are provided, because the empty tubes through their smooth walls take over the management tasks.  

The exact routing of the data and / or power lines in the recesses can be well documented and later prevents frequent drilling or otherwise opening the building wall in search of an energy and / or Data line. As a result, openings become negatively influencing the insulation avoided in the insulation.

The invention also has the advantage that the cavities of the C-profiles initially with filling profiles, consisting of the mineral wool insulation strips the insulation elements are completely filled. The individual fa in the insulation strips predominantly perpendicular to the back of the C- Profile or be arranged parallel to the legs. The insulation strip can be easily inserted into the cavity of the C-profile or into the Press in the protruding screws. The insulation strip fills the in The cross section of the C-profile is practically completely cut out and cuts roughly in a bunch dig with the folds of the C-profile. The recess then allows the one Easy and safe laying of the energy and / or data lines.

One of the side surfaces of the insulation strip can be with an adhesive adhesive be layered so that the insulation strip z. B. in the C or U profile in De corner area can be glued. The adhesive surfaces of the filling profiles can also to be directed outwards. Both outer surfaces can also be made in this way be prepared.

The mineral wool insulation boards or insulation felts can now be used easily between the straight side surfaces of the insulation strip and the opposite lying C-profile inserted into the cavity between adjacent C-profiles pushed and thereby clamped. This closes the insulation material plates or the insulation felt the recess, so that a closed on all sides Guide channel is formed. The insulation materials are used to secure the position equipped with a layer of adhesive on one or both sides.  

Suitable adhesive adhesives come u. a. Hot melt adhesives (hot melt Adhesives) in question, for example the best of thermoplastic rubber hen. These so-called pressure sensitive hot melt adhesives are used at elevated temperatures sprayed, cast or extruded onto the side surfaces of the insulation boards and then covered with plastic sheeting to maintain its adhesiveness The outer back of each neighboring C-profile can also be used with an adhesive adhesive for connection to the insulation board or the Insulation felt to be coated.

Another design option is to use composite materials Glass or plastic fibers or metal foils with foils made of thermoplastic welding or sticking plastics onto the corresponding surface ben. The high thermal conductivity of the metal foils is white on the assembly walls against the existing thermal bridges there is no additional disadvantage however, the foils are only partially, in particular parallel to the co tel axis of the side surfaces applied to the insulation.

In the case of stronger insulation boards, coatings, e.g. B. from cement or plastic mortar, water glass paints, silica sol u. a. be applied on which there are tapes.

Another embodiment of the invention consists of an approx. 5 to 50 mm, preferably about 10 mm thick mineral wool layer with the help of the factory Adhesive glue also applied to the back of the C-profile. Due to the high coefficient of friction of the mineral wool surfaces remain also little stiff insulation materials in their position.

In particular, less dimensionally stable insulation felts can be large on one or both o entire surfaces or partially with adhesive adhesives. By pressing on the rear wall covering, the situation naturally becomes stability of the insulation materials in the cavity to be insulated additionally improved.  

It can further be provided that a filler element is made in the recess Insulation material can be used in a positive and / or non-positive manner. This filler can, for example, be used at the factory and on site before the one construction depending on the use of the insulation element from the exception can be taken if a guide channel is to be laid is. If the filling element remains in the recess, the insulation element can with an optimal insulation effect as a fitting between adjacent insulation fabric panels or in C-profiles.

Furthermore, the filling element can be laid in after the power and / or data line has been laid the recess can be used to increase the insulation performance. In this The case is, however, the subsequent moving in or in of further data. and / or power lines difficult.

Further features and advantages of the invention result from the following Description of the accompanying drawing, in the preferred embodiment le are shown. The drawing shows:

Figure 1 shows a portion of a stud wall according to the prior art in a plan view shown in section.

Figure 2 is a section of a stud wall without insulation in a sectional plan view.

fig. 3 cut a section of a stud wall with insulation material shown top view;

Figure 4 shows an insulation strip with a cable duct in cut datge side view.

Fig. 5 is a stud wall with the insulation strip according to FIG. 4 in view and

Fig. 6, the stand wall of FIG. 5 in cut side view.

In Fig. 1, a portion of a stud wall 1 is shown. The stud wall 1 consists essentially of two cross-sectionally C-shaped profiles 2 and on both sides with the profiles 2 by means of screws 3 connecting elements 4 . In Figs. 1 to 3 and 6, only one element 4 is shown Verkleidungsele. Gypsum plasterboard and / or gypsum fiber boards are particularly suitable as cladding elements 4 , which can preferably be processed with such stud walls 1 .

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 and each having a bend 7 at its free end, which starts from the legs 5 at right angles to these legs 5 are aligned and directed towards each other.

The screws 3 for fastening the cladding elements 4 to the profiles 2 pass through the cladding elements 4 and one leg 5 of the profile 2 . It can be seen that the two profiles 2 shown in FIG. 1 with their legs 5 are arranged in the same direction, that is to say that the legs 5 of adjacent profiles 2 point in the same direction.

Between the profiles 2 , an insulation board 8 is arranged, which consists of mineral fibers, for example rock wool. The insulation board 8 extends from the web 6 of the first, left profile 2 to the web 6 of the second, right profile 2 . Accordingly, the insulation board 8 is inserted between the legs 5 of the left profile 2 , the two bends 7 of the two legs 5 engaging in the surfaces of the insulation board 8 .

The insulation board 8 has a material thickness which corresponds essentially 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 harmless and usually desirable in order to fill the cavity between two spaced-apart cladding elements 4 as completely as possible dig with insulating material.

Not shown in FIGS . 1 to 3, but can be seen in FIG. 5, the C-shaped profiles 2 are set in U-shaped profiles 9 fastened on the bottom and ceiling sides, the C-shaped profiles 2 with the U-shaped profiles 9 connected, in particular screwed.

When creating a stud wall 1 according to the prior art, as shown in FIG. 1, the U-shaped profiles 9 are arranged on the top and bottom sides in a first step and dowelled with screws. Then the C-shaped profiles 2 are set at a distance from one another in the U-shaped profiles 9 and screwed to the U-shaped profiles 9 . The distance between two adjacent C-shaped profiles 2 corresponds essentially to the length of an insulation board 8 to be installed subsequently.

In the next step, the frame created from the C-shaped profiles 2 and U-shaped profiles 9 is provided on one side with cladding elements 4 , the cladding elements 4 with screws 3 on the C-shaped profiles 2 and possibly also on the U-shaped ones Profiles 9 are screwed. The screws 3 extend into the space between the legs 5 of each profile 2 .

In the next step, the insulation panels 8 are then inserted on one side into the space between the legs 5 of a C-shaped profile 2 and clamped in the space between adjacent C-shaped profiles 2 .

By in the space between the two legs 5 of a profile 2 inra ing screws 3 , the setting of the insulation board 8 is difficult to the extent that the screws 3 sometimes prevent the insulation board 8 from being fully pressed into the profile 2 . In addition, an accurately spaced arrangement of the adjacent profiles 2 is required to NEN to provide the intended clamping voltage between the insulation board 8 and the web 6 of the right profile 2 . Even with slight inaccuracies in the distance between two C-shaped profiles 2 , such a compressive stress cannot be built up, so that the mounting of the insulation panels 8 between the profiles 2 is made more difficult.

Fig. 2 shows a first embodiment of a stator wall 1 compared to the above-described prior art. Here, the same reference numerals are used for matching components.

Strip-shaped insulating material elements 10 are inserted into the C-shaped profiles 2 , the volume of which corresponds to the volume of the space between the legs 5 of each profile 2 , so that the insulating material elements 10 are essentially flush with the bends 7 of the legs 5 . The insulation elements 10 are held by the bends 7 in the profile 2 .

Each insulation element 10 has two large surfaces 11 aligned parallel to one another and four side surfaces 12 which extend between the surfaces 11 and are arranged at right angles to the surfaces 11 , so that in each case two side surfaces 12 run parallel to one another and two side surfaces 12 run perpendicular to one another.

Each insulation element 10 has a fiber course perpendicular to the large surfaces 11 , so that each insulation element 10 has a relatively high flexibility in a direction of movement parallel to the large surfaces 11 . This flexibility allows the insulation elements 10 to be pressed together to such an extent that they can be inserted in a simple manner past the ends of the screws 3 into the space between the legs 5 of the profile 2 . The compression is released on closing, so that the insulating elements 10 occupy their original width again, in which the screws 3 in the insulating material element 10 engage and additionally ensures this.

The insulation element 10 has on its surface 11 facing the web 6 a layer 13 of an adhesive adhesive.

This adhesive adhesive which can be activated when the insulation element 10 is installed in the profile 2 is arranged over part of the surface 11 and connects the insulation element 10 to the profile 2 . In order to keep the adhesive adhesive tacky for a long time, without the adhesive surface being covered with dust before installation, so that the adhesive properties decrease, a film (not shown in more detail) can be arranged on layer 13 of the adhesive adhesive, for example, immediately before installation is removed from the layer 13 of the adhesive adhesive.

By gluing the insulation element 10 with the profile 2 , a safe arrangement of the insulation element 10 is achieved, which simplifies further processing, for example the subsequent insertion of insulation boards 8, in such a way that at this time the insulation elements 10 are not manually positioned must be fixed.

In addition to the insulation elements 10 , the insulation board 8 can also have layers 13 of adhesive glue in the area of their narrow sides and / or their large surfaces, so that in the subsequent step in which the insulation boards 8 are inserted into the cavity between the profiles 2 occupied by the insulation material elements 10 , the insulation boards 8 are additionally bonded to the insulation elements 10 or the covering elements 4 and / or the web 6 of the profile 2 . Overall, the construction of a stud wall 1 is considerably simplified by the embodiment shown in FIG. 3.

FIGS. 4 to 6 show an embodiment of the insulating element 10, in which the insulating element 10 comprises an insulating body 14, which is also strip-shaped. The insulating body 14 in turn has two large surfaces 11 and four side surfaces 12 ( FIG. 4), which are each arranged at a distance from one another and are oriented parallel to one another.

In a surface 11 is a continuous, open to the surface 11 Ausneh tion 15 of rectangular cross section. The recess 15 serves as a guide channel for data and / or power lines, which are not shown in detail.

The insulating body 14 has a volume which substantially corresponds to the volume between the legs 5 in the profile 2 arranged. Accordingly, the insulating body 14 can be used in such a profile 2 to provide a vertical guide channel for data and / or power lines.

Referring to FIGS. 5 and 6, a corresponding insulating body 14 may be but also formed with a material thickness which corresponds to the material thickness of mung DAEM to provided insulation plate 10. Formed in this way, the insulating body 14 represents a guide channel for data and / or power lines, which is oriented horizontally.

The recess 15 can be covered according to FIG. 6 with a cover element 16 . Alternatively or in addition to this, a filling element can also be provided, which is of flexible design and has a volume that fills the recess 15 . By such a filler, not shown, there is the possibility of using the insulating body 14, for example, according to the exemplary embodiment according to FIGS . 2 and 3, when it is not important, through a recess 15 through a guide channel for energy and / or data lines provide. On the other hand, the filling element can be removed from the recess 15 in order to provide just such a guide channel. Due to the high elasticity of the filling element, it can also be inserted into the recess 15, for example, if only low-volume energy and / or data lines are arranged there. The elasticity allows displacement or compression of the filling element, so that a maximum heat and / or insulation performance is achieved. Cold bridges or sound cavities can hereby be avoided in the stud wall 1 .

The bulk density of the insulating body 14 is increased compared to the bulk density of the insulating boards 8 processing here, so that relatively stable side surfaces are formed in the recess 15 , which also enable subsequent insertion or retraction of energy and / or data lines into the recess 15 , without, for example, inserting such energy and / or data lines into the side surfaces of the recess 15 and thus causing damage there.

As an alternative to a high bulk density of the insulating body 14, it can be provided that a plastic cable duct designed in accordance with the cross section of the recess 15 is inserted into the recess 15 .
