Description

DETAILED DESCRIPTION OF THE INVENTION This invention relates to webs of insulating material, particularly webs of inorganic fiber felt. The invention also relates to its manufacturing method and its installation method.

Constructions of this type of web of insulating material are known. Webs of insulating material with a layer of insulating material made of bonded glass wool and backed with an aluminum film are very widely used. This aluminum film bar acts on the one hand as a II wall against steam and on the other hand serves to fix the web of insulating material between e.g. roof girders; for this purpose the layer of insulating material is The inner edge surface shall be provided with laterally projecting edge pieces which can be nailed or fastened with fittings, such as aluminum film or other materials unless it is ensured that such insulating material is non-combustible. Instead of even a reinforced metal film, other materials such as backing materials such as kraft paper or even plastic-based materials can be used.However, inorganic fiber felt and aluminum film The combination of layers of insulating materials consisting of be.

One problem in this regard is that webs of insulating material are generally not used for example! ;00mm1b00mrn, riθorru, g
Although they are manufactured and sold out only in certain ratings such as oθ mm and 1000 mm, the spacing between edge boundaries, such as roof girders, varies and there are intermediate widths between these widths. It is therefore often necessary to cut such webs of insulating material in the field to dimensions adapted to the requirements of the individual case, which may result in manual removal of layers of insulating material from webs that are too wide. It is relatively labor intensive as it has to be cut out. This additional work has been avoided in actual calculations, if possible. This means not only that the web of insulating material is ideally dimensioned to be about 20 mm larger, but also generally about 50 mm larger is still acceptable, but for example about gon mm or more. This means installing a web of insulating material of larger dimensions. However, such clumsily installed insulation webs cannot fully perform their function. The reason for this is that the edge pieces of the insulating web backing become wrinkled, creased, or puckered, so that they no longer function to meet the requirements as a steam barrier.

Despite the relatively large size of the insulating material, and in order to facilitate the lateral pressing of the layer of insulating material to avoid as much as possible the hassle of cutting the insulating material to size, the layer of insulating material Allowing relative movement in this area of the layer of insulating material and the backing without applying adhesive to one lateral edge area of [14J] is disclosed in U.S. Pat. L dako, No. 20 and German utility model registration No. gO
/! ;g! It is known from No. 14.

However, although this procedure is intended to optimize dimensions significantly larger than the required dimensions, it still produces unacceptable results even for edge areas that are not adhesively applied, and that It is difficult to seal at the edge pieces of the backing because it cannot be avoided that strains are introduced into the backing while pressing the sides of the insulation layer. This installation difficulty is accompanied by the difficulty of pressing the edges of the insulation layer into place during the removal of the insulation material.Furthermore, the lateral edges of the insulation layer may be pressed under pressure. When pressed, the edge piece pressed into the gap between the inner lining of the insulation and the outer closure material, such as the roof ink, is irregularly positioned, resulting in a thermal insulation effect in this area. If the gap between the roof ink and the turned-up edge piece is filled, condensate will accumulate in this area due to insufficient ventilation behind the insulation.

Known means of fixing the edge area of the insulation layer to the backing material without adhesives, thereby facilitating deformation during installation, do not solve the problem of installing significantly thicker insulation strips. , on the contrary, the overly large insulation layer is simply forced between the edge boundary sections, so that the attachment compresses the edge areas within.

German utility model No. 7830g! No. f discloses a similar type of insulation web, in the edge area of which there are relatively wide notches in the insulation layer at a distance of approximately / Omm, these notches Separate the lip of the insulation material between the gaps. the notch extends through a portion of the thickness of the insulation layer;
The lining material, which forms a moisture vapor blocker in these notch areas, is not attached by adhesive and loosely covers the insulation without bonding to each other, so that the lining material lifts the edge areas and closes these notches. The backing material can be cut away from the insulation layer at appropriate areas to give the insulation layer the desired width.

The disadvantage in this case is that the relatively wide groove-like cutouts naturally reduce the insulation capacity of the insulation layer in these edge areas, and the lateral insulation lip must be less in order to satisfy the insulation. First, if the width of the insulating material layer is adequate, the groove-like recess is retained in its entirety, and the thermal insulation capacity of the insulating material is correspondingly significantly reduced in its edge region. Furthermore, since they are only connected to each other by a thin web of thermal insulation material at the bottom of the cutout, the insulating ribs have the disadvantage of being accidentally damaged or cut. Finally, groove-like notches must be cut into the corresponding shape with a saw or a cutter in the insulation layer. This means, in other words, that a large amount of waste is generated, on the one hand, a relatively large amount of material is lost, and on the other hand, the removal of the waste requires considerable expense. This is true the wider the width of the material is, and if the material is a material that is not easily compressible, e.g. a rigid foam, it still achieves sufficient elastic retention for the necessary edge compression. It's true.

In order to avoid these drawbacks, according to the German Special Publication No. 3//g!;97, the current state of the art is that the backing material is already completely separated from the central area and continuous with the edge areas during the manufacturing process. It is known to create edge areas with y4 edge pieces obtained by gluing.notches obtained in the manufacturing process of the insulation to avoid gaps in the lateral cut-out edge pieces. are fully bonded again before lining,
In this case, a retaining action along the ends of the sections is effected by the gazing stop, and this is also possible due to the consistency of the binder in the insulation material 11'3 when the sections are joined together. However, gaps can always be created selectively by hand by removing the backing material on the desired section, and the removed edge pieces thus created can overcome the holding power of the adhesive and be removed. I can do it.

Due to the opposite properties of the notches, insulating webs of this type do not differ in appearance and thermal insulation properties from insulating webs without notches. The reason for this is that most of it is invisible and its effects are easy to see. However, in the event of improper handling, a cut gap may form where separation is not desired. Cuts that create such gaps make normal installation difficult. A number of notches are provided in each edge area of the insulation layer in order to limit excessively large dimensions and to limit the edge compression to a certain level as much as possible (the edges between the individual notches are The width of the pieces will be relatively small so that during normal installation, the compression of the relative dowel edges is sufficient to force the adjacent notches into the gap, and the side edges of the side edges will not collide. Finally, lifting the end piece to be removed from the bonded backing material due to improper handling or carelessness may result in damage to the backing material and, therefore, damage to the water vapor achieved by the backing material. Risk of damage due to occlusive effects.

Thus, German Publication No. J//g! German utility model registration by issue 9'/7g-, 30t! f-Last industry developments have resolved many of the deficiencies in the current state of the industry, but proper installation requires some care and knowledge. However, this is not necessarily a prerequisite, since the installation of insulation webs of this type is increasingly carried out by inquisitive craftsmen and not by unskilled purchasers.

Unlike such prior art, the present invention has special features d'1
- Insulating webs of the type indicated in the preamble of the claims, as well as their method of manufacture and their installation, provide a method in which the module edge pieces do not have to be removed for installation; If the installation of the material web is easy (if there is no functional difference in comparison, if it can be manufactured with virtually no extra cost, and if it can be installed neatly even by unskilled people) The web and its manufacture and installation provide a method.

Regarding the device, this problem is solved by the features of patent claim 1, while from a method point of view it is solved by the features of patent claims H, S and 6.

According to this invention, German utility model registration No. 7g30g3.
No. 2 and German Patent Publication No. J//g! ; the notches in the insulation layer according to No. 9'1 do not weaken or in any case significantly mechanically weaken the insulation, and are replaced by marking lines that can only be visually identified by coloring. In this way, the known cutout remains as a visually discernable separation line, and pretreatment of the insulation layer by mechanical action is eliminated. In this way, the above-mentioned disadvantages of the above-mentioned notches are eliminated and the conventional developments directed to the mechanical preparation of the insulation layer to facilitate the removal of the edge piece module are discarded. However, the edge area of each insulation layer with a separating line is kept without adhesive between the insulation layer and the line, a requirement known from the relevant German utility model No. 9g30g52, so that the German The development direction disclosed in Patent Publication No. 3//9A;97 has been discarded. Within the framework of the invention, this non-adhesive edge area is cut below the marking line selected for cutting when removing the edge piece between the insulation layer and the backing material. It serves to insert a cutting tool in the form of a plate or strip, so that the desired cut can be made quickly and cleanly, for example with a knife, without risk of damaging the backing material.

Therefore, as described in claim 6, the user selects all the marking lines (to cut along this line) for attaching the insulation web, and then inserts the cutting tool into the insulation web. , and then immediately make the cut along the predetermined marking line in one go, without the need for a cutting board or similar aids, so that the entire knife follows the direction of the marking line.

The marking lines have no mechanical effect on the insulation layer, so
Even if the spacing between the marking lines needs to be relatively small, they can be applied at the desired spacing, and the width of the insulation layer can be adjusted as accurately as possible depending on the individual case, and the installation can be made to suit the conditions. I can do it. At the same time, the marking lines according to claim 2 can be provided on both sides of the insulation layer, in fact the edge pieces delimited by the marking lines can have different widths in the edge areas of the insulation web. can also be modular.

Since the cutting can be carried out quickly and easily as described above, there is no need to cut only one side of the insulation web as far as possible, but at point a along the selected marking line. The combination allows one to approach the ideal width or width of the insulation web for the particular job at hand. Although the number of marking lines has no technical effect and can therefore be increased, it is advantageous to limit the number of marking lines. The advantage is that in that case the marking lines can be easily drawn into lines of different appearance, so that the user of the insulation web can draw between a limited number of marking lines without any aids. This is because the intervals can be easily identified. Such different landmarks i are, for example, continuous lines (
as a solid line) or as a line consisting of short dashed lines, or as a line consisting of a short dashed line.
d long dashed or dotted lines can be applied and at the same time give information about the spacing between the individual marking lines and between the opposite insulation layer edges. Having ascertained the actual spacing between the edge boundaries, the operator then reads, for example from a table, the marking lines he would cut to obtain the optimum installation conditions. In this way, even inexperienced operators can reliably avoid defects due to improper installation.

Marking lines on an inorganic fiber felt layer with a relatively irregular surface can be applied by means of a hot air stream, e.g. a hot air jet (which is operated intermittently to create broken lines) Marking lines can be particularly easily marked by narrowly localizing the binder inside and applying marking lines by the discoloration caused by heating only on the surface to the decomposition temperature of the binder. can.

Such a hot air jet can be arranged, for example, at a post on the production course at a predetermined location in a lateral area of the inorganic fiber felt production course, and by continuous or intermittent generation of the jet, the insulation according to the invention can be The production of the material web does not require any changes in production equipment or operations other than this simple additional equipment.

Further details, features and advantages of the invention will become apparent from the following description of embodiments illustrated in the figures.

The figure shows a perspective view of a lined insulation web according to the invention.

The insulation web shown in the figure consists of an insulation layer 1 and a web of backing material attached by adhesive to one side of the insulation layer. The well-beaten webco can be, for example, a kraft paper, but is preferably a metal film, such as an aluminum film, which metal film may optionally be provided with a reinforcing layer, such as the reinforcing layer known from German Patent Publication Aoi 3t Ko 3. You may be prepared. In principle, the insulating material layer may be any suitable insulating material, but insulating materials with relatively high compressibility,
Inorganic fiber felt is particularly preferred.

In terms of installation, the web 2 of the insulation layer is supported from below on the inner edge of the roof girder by a lining web 2 with a protruding edge piece 3 between the adjacent roof girders, etc. The lining web can be attached to this roof girder abuttingly, such as by glazing, while the insulation layer is located between the girders. Install it beforehand, and if you replace it, the insulating material layer l should have a width B of 1110 mm - 1 at the position shown in the figure.
jJ is approximately 30 mm larger than the spacing between adjacent roof girders or other outer edges tQ, but it is always larger by θ than the distance between adjacent roof girders or other outer edges tQ, so it is necessary to compress the insulation layer a little in the direction of B. A lateral installation pressure of

As can be easily understood, such webs of insulation are only manufactured in certain nominal (rated) widths, i.e. perhaps in steps of 100 mm between soQ and 1ooo. From, creating a rated medium with a slight difference in width that can be made to fit any possible application is &! The production cost is very high and storage requires multiple chicks. Furthermore, since the spacing of adjacent roof girders is often slightly different, if the user can obtain a wide variety of precisely matched insulation strips, the user can check the spacing of each roof girder before making a purchase. If you virtually predict all the differences in width between the individual spaces and gaps between the roof girders in advance and install the insulation strips according to that prediction, you will be able to create an equal number of each type with different widths smaller than about 70.0 mm. There is no great advantage in making products.

For installations in between ratings, in order to match the insulation layer to the width,
It is necessary to match the rated medium B of the insulation material layer l to the installation location, and compared to the rated medium B of 100 On, the insulating paulownia layer, which is available in a larger size, has an intermediate dimension, for example, q5θ.
must be reduced to a struggle.

For this purpose, the insulation layer l is provided with transverse marking lines 4 (, 5 and 6) on the opposite side of the backing web, between the backing web and the adjacent side of the insulation material l. In this case, an adhesive layer g for fixing the raised web 2 to the insulating material layer l is provided in the intermediate area between the marking lines without bonding with an adhesive.

In the example illustrated in the figure, the farthest marking line on the left is provided at a distance of about 25 degrees from the near end of the insulation layer l, and is adjacent to the inside of the marking line q. The landmark line S on the left side is provided at a distance of approximately Sθ Kaoru from the landmark line q. On the opposite side there is only a marking line 6, which is provided at a distance of approximately SO length from the near end of the insulation layer l. Marking lines Q, j and 6 connect the edge pieces +a, , ta and 6a, which are provided to reduce the rating medium B if necessary, between the adjacent lateral edges of the insulation layer l. compartmentalize.

By selecting and installing marker wires 5 and 6, approximately 2 JRAM is reached until the next smaller rating r9B (which is approximately / 00 am smaller than the medium B rating of the insulation web in question) is reached. Rated B with gradual reduction
can be selectively reduced. Approximately B in the rating
In order to reduce the size by 23 steps, cut along the marking lines to remove the edge piece a. In order to reduce the size by B Q k Oam during the rating, cut only at the mark line 6 and remove the edge piece Aaf. Finally, B f 7 is rated! ;trv
If it is necessary to reduce by r, cut along mark line S to remove both edge pieces 9a and &a.

If it is necessary to reduce 13 of the insulating material layer by more than 73rrnn, it is sufficient to use the following smaller ratings.

However, the necessary In this case, d: Naturally, a mark line is added.

If necessary, mark line 9.3 and The insulation web may be provided with a chart indicating which marking lines should be cut.

For this purpose, mark line q as shown in the figure.

For example, A is a solid line, S is a broken line, and q is a dashed line. For ease of understanding, each insulation layer/layer χj

It is only necessary to cut each insulation material layer once according to If necessary, especially if the dimensional difference between adjacent short bath dimensions 11]B of the insulating material webs is large, a number of marking lines can of course be inserted between one side of the insulating material layer. These marking lines may be at a certain distance from each other, such as θ, and the cutting lines of the yuku can be appropriately cut with the desired marking lines. For example, at least 25 mm from the edge of 149 so that any intermediate dimension within a relatively wide range can be covered by combining the
A mark or line may be placed at the distance hi[.

The central section 70 of the insulation web has side edge sections 1a on both sides without adhesive IQJ g.

Removal of the 5a or 6a gold trim is extremely simple and requires no intervention to remove it from the backing. However, an even greater practical advantage is that in the edge toe region, the inner web 2 can be easily lifted off in the instant contact area of the insulation material C with the cutting tool shown in the figure. (It has the shape of a plate like a cutting blade or a thin J-shaped piece) can be used as an intermediary between UEPCO and the insulating material t= /. After inserting such a cutting tool 9 as shown at 111 on the right side of the figure, the user can cut it along the landmark line 6, which is the desired landmark in this example, without taking special care. Simply cut the insulation 4j layer from above and remove the insulation completely without risking damage to the backing material.

Instead of applying an agent, it is preferable to intentionally change the color of the binder. For this purpose, K is 41. If a jet of hot air at a temperature of, for example, about 1.00°C is blown onto the surface of the web passing through during the production of a self-edging web, the jet of hot air will be directed to the center of C5.

In this way, the marking lines can be applied virtually without hindrance, and this is due to the interlocking of the insulation layer from the inorganic fiber felt.

This is especially important for manufacturing processes.
