Description

Insulation for clamping equipment between beams of roof rafters or other wooden structures

These insulating materials (or insulating material elements) are known and are used to clamp the installation of roof panels, balconies or other limited surfaces, especially sheets or sheets selected from the sheets and selected insulation panels. This is a market with a production index that has grown for decades, and the insulation sheet may be installed on-site by construction professionals, but is often also used by do-it-yourselfers who are unskilled, Lt; / RTI > These insulation sheets, also called clamping felts, have steadily increased their market share since insulation of steep roofs, especially with mineral wool, has become commonplace in the market.

In the production and inventory maintenance of insulation, it is very generally considered that manufacturers can vary considerably the widths between the beams of roof rafters or other wooden structures and their height, i.e., the lattice depth . For these reasons, for example, so-called shoulder mats are prepared for fitting to different widths between rafters or beams, for example with inventories of finely graded widths with a width gradient of 100 mm. Clamping felt thicknesses of about 80 mm to 22Omm and above are also currently provided. This, of course, not only produces, sells and distributes but also enormous inventories on the building floor.

Another special problem with these products is the essential material cost, which is always important because of cost reasons, but it is especially important for the required applications such as steep roof insulation, because the overlying surfaces must be covered with insulating material. In addition, considerable material costs are further exacerbated by this, especially since the mineral surface must be produced incrementally from a biodegradable composition or produced according to specific national regulations.

The present invention relates to a heat insulating material according to the preamble of claim 1.

It is an object of the present invention to provide a roof rafter, beam or other limiting surface that optimizes the product to the use of the material necessary to meet the technical service value, in particular the insulation capacity, And to provide a heat insulating sheet or an insulating panel for clamping equipment between the heat insulating sheet and the heat insulating sheet.

According to yet another object, the insulation for clamping the installation between the beams of the roof rafters or the wooden frame structures, as compared to conventional insulation, saves material and nevertheless has an optimum clamping effect, Transport and packaging through the reduction of the volume of the packaging in terms of the fact that they are distributed in a foil package.

Another object of the present invention is to provide a heat insulating sheet or a heat insulating panel in a thickness range which ensures complete insulation as a heat insulating material having a constant thickness for different and various beam thicknesses (lattice depth), and in particular enables continuous compensation of different thicknesses . The insulation sheet should nevertheless be easy to produce and the installation of the insulation sheet or insulation panel should not be damaged by simple clamping.

This problem is solved according to the invention in the features of claim 1, and particularly preferred embodiments are characterized by the features included in the dependent claims.

The present invention is mainly characterized in that said insulating sheet or panel has a special clamping type support element, also referred to hereinafter as a clamping layer. This allows a considerable material savings in the entire insulation layer, since only the panel or sheet clamping type part needed to clamp the installation needs to be designed in terms of its clamping function characteristics to ensure complete and continuous support of the material do. The remainder or remaining layers of the panel or sheet can be adjusted without the aid of clamping and support functions, e. G., With less elasticity than the clamping layer, especially with lower volume densities, Need to be. For example, by classifying the volume densities within the panel or sheet, considerable material savings can be achieved, especially in view of the fact that considerable surfaces must be insulated in the intended application case of steep roof insulation. In the given case the properties of the clamping layer are obtained by the higher bulk density over the remaining layer. Higher volume densities are used here to achieve the clamping function of the clamping type support element. The volume density in the remainder of the heat-insulating sheet or panel can be selected in accordance with a particular requirement profile, especially in terms of heat conduction. The clamping layer also meets the requirements for insulation.

In a particularly preferred embodiment, the panel or sheet is divided into two layers, one of which forms the clamping layer and which, in particular, has a greater volume density than the remaining layers which perform only a filling or adiabatic function And has a large elastic force. Properties such as the elasticity of the clamping type support element can also be achieved by appropriate adjustment of binder content and / or fiber quality and / or fiber orientation, as well as increased bulk density.

Multi-segmentation, in particular double segmentation, of the insulation to at least two parts with different properties achieves a reduction of the material according to the invention, while maintaining or optimizing the clamping effect on the conventional mineral surface insulation, The dog parts act as a clamping style. For this purpose, any sagging due to the weight of the insulation takes place, for example, in a condition equipped between the roof rafters, so that the clamping layer, which is preferably located at the top in this case, So that it has a clamping inducing effect. Since the volume density of the remaining insulating layer acting as a filler layer can be minimized in accordance with the present invention, the product can be compressed more favorably so that not only material savings but also considerable packaging advantages can be achieved. This is particularly advantageous as an insulation which is supplied in roll form because it significantly reduces the packaging volume and results in a reduced transport and storage volume.

It is also possible to provide two filling layers or two clamps in the case of only one filling layer with a particularly preferred double layer embodiment of an insulating sheet or adiabatic panel. The number and arrangement of filling layers and clamping layers may be selected accordingly by a skilled person.

As mentioned above, the specification of the clamping layer can also be adjusted by the geometry of the fiber, the location of the fiber, the fiber formation, the orientation of the fiber, the binder content or other additives that enhance the clamping layer, rather than by volume density have. The clamping layer is required to have sufficient spreading or elasticity to ensure the required frictional force between the clamping layer and the critical surfaces. This means that the clamping layer is sufficiently rigid that the insulation can be clamped and clamped between the rafters with sufficient pressure, while the filling layer is softened and compressed sufficiently to enable thickness compensation function at different lattice depths It is generally considered possible. When the elastic force is controlled through the volume density, the ratio of the volume of the clamping layer to the volume density of the filling layer is preferably greater than 1, and more preferably greater than 1.5.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, preferred embodiments of the present invention will be described with reference to schematic drawings.

The insulating material in the form of a heat insulating sheet or adiabatic panel 1 shown in partial perspective view in Figure 1 consists of two layers, a filling layer 2 denoted FS and a clamping layer 3 denoted KS . The two layers have different properties and thus also have different properties. In the case of the preferred application, that is to say in order to clamp the installation of the insulating sheet or the insulating panel 1 between the rafters of the roof structure or between the columns of the wooden frame structure, The layers are designed with different volume densities. The clamping layer 3 is designed to clamp the installation of the sheet or panel at its density and has a much larger volume density than the filling layer 2 in particular. The filling layer 2 can be designed independently of the clamping function and thus has a reduced bulk density, the density of which is chosen only for the purposes of the required adiabatic properties.

Fig. 2 shows a heat insulating sheet 1 cut from a sheet wound with a heat insulating material roll according to Fig. 5 in a position provided between two adjacent rafters 4 of a steep roof structure, Which is conventionally used in the work and disposed on the upper surface of the rafters 4. Fig. 2, the clamping layer 3 is arranged on the top, that is, on the roof surface, and thus adjacent to the waterproof sheet 5, whereas the filling layer 2 is directed towards the room That is, the lower portion. The insulating sheet 1 shown in Fig. 2 is adjusted to the thickness d3 of the rafters in terms of thickness, but this is not necessary in this case. The layer thicknesses of the clamping layer 3 and the filling layer 2 are denoted by d1 and d2. For the installation, the insulating sheet 1 is cut from the roll according to FIG. 5 with an overmeasure above the width D between the adjacent rafters 4, So as to be supported by the clamping effect. A useful surplus for conventional squares is about 1 cm.

The two layers 2 and 3 are formed from mineral surfaces as described above, but they differ in mechanical properties. These different properties are achieved in the embodiment of FIG. 2 by the different volume densities of the layers 2 and 3. The filling layer 2 has a volume density lower than the volume density of the clamping layer 3. The clamping layer 3, which has a much higher volume density, has a higher elastic force between the limiting surfaces than the filling layer 2, and the elastic force is such that the insulating panel does not need special fixing means, So that they can be tightly fixed and arranged. A suitable volume density for the clamping layer is at least 10 kg / m < 3 >, and a preferred range of application for clamping equipment between pillars of rafters or wooden frame structures is a density value in the range of 10 kg / m3 to 30 kg / m3. A particularly preferred range for the volume density is 15 kg / m3 to 25 kg / m3 and a particularly preferred volume density for the clamping layer is in the range of, for example, 17 to 19 kg / m3.

In applications for roof insulation such as so-called frames between facing rafters and squares at a roof slope of less than 60 °, particularly for application to insulation of horizontal wooden lattice structures, the volume density of the clamping layer 3 So that it is essential for the clamping layer 3 to be flexible, without being buckling under the load of the heat insulator 1, which is sufficiently strong and rigid and nonetheless composed of the layers 2 and 3. 2, the insulating sheet can be slightly deformed under its load, and some sagging or bulging down may occur especially in the lower region of the filling layer 2, between the rafters 4, Resulting in a spreading force. Clamping fixation of the heat insulating sheet between the rafters 4 is mainly by restitution and frictional forces formed by the clamping layer 3 which is caused by the spreading forces So that the frictional forces of the filling layer 2 across the rafters 4 also contribute to the clamping effect. Therefore, the clamping is carried out by the filling layer 2 through the punching force induced therefrom by the actual clamping layer 3 whose strength is designed for the purpose of the clamping function and the deflection of the insulating sheet by the load, ≪ / RTI >

De-spreading of the insulating sheet 1 between the beam surfaces of the roof rafters or the beams of the vertical wooden frame structures is also possible, whereby the filling layer 2 is positioned adjacent to the waterproof sheet 5 in the roof area, The floor is facing the room. However, with vertical wooden frame constructions, the filling layer 2 with the outer surface of the clamping layer 3 co-planar with the outer surfaces of the beams can, for example, extend to the wall panel 5, such as a derived wood panel Filling the remaining space, and thus acting as a compensation layer. That is, due to the excellent compressibility of the filling layer 2 designed to have a low bulk density, different beam thicknesses d3 can be connected to the same insulating material. For example, connecting the different thicknesses in the range of 140 mm to 220 mm continuously with the insulating panel 1 having a thickness of 220 mm by performing the compensating function when the filling layer 2 is somewhat compressed and thus the insulating panel is integrated I can think. This is an exemplary value, as well as the aforementioned value 220 mm for the overall thickness d1 and d2 of the insulating sheet 1, as well as the thickness of the product can also be adjusted to different lattice depths. It is also possible to use two products of different thicknesses having a uniform gradient if necessary or three products of different thicknesses with a uniform gradient. This ultimately depends on the functioning of the market, especially the expected difference in beam thickness or rafter used for each structure. This may vary from country to country due to the corresponding examination of the building code.

Figures 3 and 4 illustrate the state of the installation for an insulating panel or insulating sheet between vertical wooden frame structures, for example with columns or beams used for building walls, in particular for industrial prefabricated room modules. By way of example only, the outer side is indicated here by a wall panel 5 'of a derived wood product or panel. Figure 3 shows the beginning of the installation process, in which a filling layer formed as a compensation layer 2 'is located in the space between the two beams 4'. The clamping layer 3 is then compressed between the beams 4 'by the application of a force P so that the outer surface of the clamping layer 3 is pressed against the outer surface or outer edge of the beam 4' As shown in Fig. When the clamping layer 3 is compressed, the compensation layer 2 'is correspondingly compressed so that different beam thicknesses can be associated with the same product, i.e. with the same thickness of insulation, The compensation function is also performed. In the case of this application, the clamping layer 3 has a higher strength over the compensation layer 2 ', in particular to have a higher bulk density, and the above-mentioned ranges can also be applied here. In the case of two applications for the filling layer, the volume density is less than or equal to 30kg / m3, in particular less than or equal to 15kg / m3 and preferably less than or equal to 10kg / m3, the two volumetric densities being dependent on the volume density of the clamping layer Ratio is greater than one.

The specific thickness d1 of the clamping layer 3 is minimized to the technically required thickness required to secure the insulating layer between the corresponding limit surfaces of the roof rafters or beams of the wooden lattice structures in all applications. The specific values for these thicknesses depend on the construction of the wooden frame structure and, in particular, the widths which are connected between adjacent rafters or beams. As for the fill layer 2, it is generally advantageous to be able to be more compact than the clamping layer 2, which on the one hand enables the abovementioned compensating function, but on the other hand it also provides advantages, do. Thus, it is possible to realize an adiabatic roll having a reduced diameter but having the same length as the insulating sheet, which reduces the packaging volume and thus provides considerable transport and storage advantages. The insulating sheet in roll form can be extruded in the range of 1: 2.5 to 1: 4.5. With this heat-insulating sheet or panel panel cut from them, the classification of thermally conductive material 045 in accordance with DIN 18165 can also be obtained, which, due to its bulk density, belongs to heat conduction 045 and the clamping layer By volume density thereof, belongs to category 035 of the heat conductive group, whereas in the central part the said insulating panel or insulating sheet meets the criterion of heat conduction group 040 in accordance with DIN 18165. By appropriate selection of the volume densities RD, the equation of (lambda) lambda = f (RD) is well known and the total heat transfer coefficient 035 can also be obtained.

Fig. 5 shows a particularly preferred embodiment, namely a heat insulating sheet wrapped in rolls for clamping equipment between rafters or beams, particularly between the limiting surfaces of steep roof rafters. The insulating sheet 6 is shown in a partially unfolded state. Numeral 2 again denotes a filler layer having a compensation function, and numeral 3 denotes a clamping layer, which is arranged outside at the winding position of the insulating roll. The clamping layer can also be arranged inwardly in the wound position, which depends on the application in accordance with the description according to Fig. 2, i.e. the actual installation conditions. On the surface 7 of the layer located inwardly in the wound position, i.e. the filling layer of the embodiment described herein, there are presenting lines 8 extending perpendicularly to the side edges 9 of the insulating sheet 6 do. In the embodiment, the display lines 8 are applied at the same distance, and the distance d between two adjacent display lines is preferably 100 mm. As shown in Fig. 5, the display lines 8 need not be represented by solid lines and can also be indicated by dashed lines. The indicia lines 8 are preferably not optically formed so as not to be cut or similar and not to affect the treatment and effectiveness of the mineral face sheet 6 material. For example, in order to fill a square having a given width of 700 mm, the indication lines 8 are taken into consideration at the tip 10 of the heat insulating sheet 6, taking into consideration, for example, To measure a longitudinal portion L having a length of 710 mm. For this, the knife is cut in the direction of the arrow 13 parallel to the adjacent marking line 8 with the knife 12 on the cutting line measured by the method shown in Fig. 5, and the material is cut out.

The heat insulating panel 14 thus cut is rotated for the installation so that the outer edges 9 of the heat insulating sheet 6 first go to the top and the bottom so that the longitudinal portion L is the width of the mineral surface panel 14 . In this position, the mineral facade panel 14 is inserted into the square between two adjacent rafters 4. In the embodiment, a surplus value of the longitudinal portion L exceeding the width D of the square at a facility location of 10 mm or more allows for the required compression fixation of the mineral facade panel 14. After insertion into the rafters 4, the mineral face panel 14 is thus clamped between the rafters through a clamping effect. The heat-insulating sheet 6 thus formed can be used with a uniform width so that the panel 14 is placed on a square having a different width D between adjacent rafters when the panel 14 is cut from the heat insulating sheet according to the width D between rafters. 5, having a uniform width dimension of the insulating sheet and a uniform thickness of the insulating sheet for squares or bays having rafters and beam thicknesses d3 different from the width D due to the possibility of simultaneous compensation, Sheets can be used. This is because a heat insulating sheet of uniform width and thickness does not need to be maintained with finely graded thicknesses yet, but the wood frame with different widths between rafters or beams and having different lattice depths The ability to cover structures and various roofs results in significant savings in assortment.

Fig. 6 shows the savings potential of the insulation for conventional insulating sheets available on the market as a percentage. Significant savings, in particular in the range of 10 to 23%, can be achieved with respect to the thickness of the insulating sheet or panel, which is typically used for insulating roofs, which leads to a considerable reduction of material in terms of the amount of insulating sheet used each year for this purpose Bring it.

Table 1 shows variants of layer combinations, showing different thicknesses, volume densities, and weights per unit area of open-walled sublayers.

The table shows that all variations according to the present invention have a lower weight per unit area than the standard and thus result in a significant reduction in material. It is also shown that the layer thickness, volume density and weight per unit area of the sublayers can be varied accordingly.

For example, if the thickness of the rafters is adjusted so that they can be compressed during installation, depending on the height of the rafters or the wood grid depth, it is possible to optimize the classification as well as reduce the material, albeit slightly. For example, when the sheet / panel of Modification 3, having a thickness of 220 mm and a weight per unit area of 2.82 kg / m 2, is compressed to a beam thickness of 180 mm, it has a thickness of 180 mm and a weight per unit area of 2.88 kg / It can be seen that material savings of 0.06 kg / m < 2 > can be achieved compared to sheets / panels in the reference version. The advantages in this embodiment are mainly in the optimized classification. A more pronounced material reduction is given, for example, with a beam thickness d3 of 200 mm, but here a variant in which the weight per unit area of the reference version of 3.00 kg / m 2 is 220 mm thick and has a weight per unit area of 2.82 kg / 3 is significantly higher. The reduction of the material is therefore 0.18 kg / m3 in the above embodiment.
