Description

Title: Covering band

Technical Field

The invention relates to a covering band for use on construction materials, said covering band comprises a covering strip.

Background Art

Often in e.g. office buildings gypsum boards are used as walls because they easily facilitate resizing of the rooms. For instance a large room, which needs to be sized down in small rooms or offices. Typically, this is done due change of requirements according to change of tenants or changing needs of the same tenant. During constructional work the work site is often being shielded with walls made of gypsum boards in order to keep dust inside and unauthorised people out. In both situations the gypsum boards are placed in temporary locations and thus they often need to be taken down shortly after mounting. Although they might be a temporary construction, the walls made of gypsum boards are build with a proper finish by using filler material, paint etc. These finishing materials constitute a problem when removing the gypsum boards due to the difficulty in finding the fastening means fastening the gypsum boards to the framework. Furthermore, if the fastening means are found the filler material or the paint is filling up the notch of the fastening means, e.g. screws, and thus obstructing the possibility for screwing the fastening means out.

Thus, the walls are demolished using saws, hammers etc. by which process the gypsum boards are broken into pieces along with the framework they are fastened to. This method of demolishing the walls results in several problems. The gypsum boards are broken and therefore not reusable. Due to the increasing environmental consciousness and legislation protecting the environment as well as the demolition workers, the gyp- sum boards must be separated carefully from the framework material in order to be able to recycle the gypsum. Thus, costly time is spent separating the gypsum boards from the framework. Furthermore, in e.g. office buildings the walls are insulated and if the insulation material is contaminated with gypsum particles, the insulation material is not reusable and contamination of the insulation material by gypsum particles should therefore be avoided. Finally, both transportation of demolished gypsum boards and the new boards to be installed are costly. Especially in high-rise buildings the transportation inside the building is time demanding and should be avoided.

Description of the Invention

Its an aspect of the invention, at least partially, to overcome the disadvantages of prior art mentioned above and to provide a covering band which facilitates easy access to hidden connecting means, whereby e.g. gypsum boards can be dismounted without destroying them and thus facilitating that they can be re-used.

This aspect and the advantages becoming evident from the description below are obtained by a covering band provided with one or more threads, which extend in the longitudinal direction of the covering band.

During the installation of the wall, e.g. a wall made of gypsum boards, the covering band is held or adhered to the gypsum boards in such way that the covering band covers the fastening means, e.g. screws used for fastening the gypsum boards to the framework. This way, the filler, paint, wall paper and similar added on the gypsum boards in order to cover the fastening means and get at smooth finish, will not be able to get in contact with the fastening means. When the one or more threads are pulled, the thread cuts through all the materials, i.e. both the other materials of the covering band and the materials used for a proper finish of the wall, e.g. filler, paint, wall paper etc. This way, an opening is achieved and it is possible to break off the finishing material and thus expose the fastening means. As the fastening means has been covered by the covering band, the fastening means is easy to unscrew and it is possible to dismantle the wall - board by board.

In one embodiment of the invention, the covering band may be provided with one thread and said thread is placed in the middle of the covering band. In this way it is possible to pull the thread and flip the two halves of the covering band to the side, thus exposing the fastening means.

In another embodiment, the covering band may be provided with two threads, which are placed at the edges of the covering band. When pulling the two threads, the section of the covering band between the two threads will be cut loose from the material cover- ing it, e.g. filler and wall paper. This results in the material between the two threads being easily loosened and peeled away.

In yet another embodiment, the thread may be made of a suitable plastic or metal, such as steel or copper. The thread needs to have sufficient strength to cut through the material covering it. Various thread thicknesses could be used for this purpose, e.g. a metal thread with a thickness of 0.1-1 mm.

In addition, the adhesive layer may be an adhesive tape.

The adhesive layer may be water-activated glue or a water-activated gum. Since the gypsum boards are covered with paper, water-activated glue could result in a strong connection between the gypsum board and the covering band.

In another embodiment, the covering strip may be paper. The covering strip prevents e.g. filler from getting in contact with the fastening means. The covering strip may be any material, e.g. thin polyolefin or linen, which has the capability of preventing e.g. filler or similar successive constructional layer from getting in contact with the fastening means.

In yet another embodiment, the thread may be fastened to the covering band by gluing, moulding, stapling or sewing. If the thread is added to the covering band during manufacturing of the covering band, the thread or the treads could be moulded in the actual covering strip. Depending on the type of material chosen for the covering strip and thus the covering band, the method of fastening the thread to or incorporating the thread in the covering strip could vary.

An additional embodiment, a covering band may have two threads, where the threads may be incorporated in the covering strip by folding a side section of the covering strip around the threads and thus encase the threads in both sides of the covering strip.

In another embodiment, a section of the covering strip may be a mesh. If a section of the covering strip is a mesh or similar penetrateble means, e.g. filler could be allowed to penetrate the covering strip in that particular section. Some suppliers of gypsum boards specify that filler needs to penetrate the small crack between two juxtaposed gypsum boards for specific use of the gypsum boards. When only a section of the cov- ering strip is a mesh, the specifications of the suppliers can be fulfilled without risking filler material getting in contact with the fastening means. Furthermore, more than one longitudinal section could be of mesh in order to achieve penetration of filler in more than one predetermined areas.

In a preferred embodiment of the covering band for use on construction materials, said covering band may comprises a covering strip, wherein the covering band is provided with one or more threads, which extend in the longitudinal direction of the covering band.

Furthermore, the invention relates to the use of a covering band according to the claims 1 to 8 wherein the covering band is mounted on gypsum boards so as to cover the fastening means by which e.g. gypsum boards are fastened to a wall or a framework.

Use of a covering band according to the present invention, when installing a wall made of gypsum boards and a framework, renders it possible to dismantle said wall in such gentle manner that the gypsum boards reusable. Furthermore, the risk of contaminating insulation material is minimised.

Detailed description of the Invention

Fig. 1A shows a covering band 1 having an adhesive layer 2, two threads 3 and a covering strip 4. By way of example, the covering band 1 is in the following shown with an adhesive layer 2.

Fig. 1 B-1 E show cross sectional views of a covering band 1. Various ways of connecting the thread 3 to the covering strip 4 are shown.

Fig. 1 B shows that the covering strip 4 is positioned relatively tight around the threads 3 and that the adhesive layer 2 is connected to the covering strip 4. The adhesive layer could e.g. be a glue added to the non-sticking covering strip 4 or a self-adhesive tape adhering on both sides.

Similarly to Fig. 1 B, Fig. 1 C shows an embodiment of the covering band 1 in which the adhesive layer 2 is applied on the covering strip 4 before the threads 3 are mounted. In this embodiment the adhesive layer 2 is sufficiently adhering to keep the threads 3 in the desired position.

Fig. 1 D shows that the threads 3 are moulded into the covering strip 4 and that an adhesive layer 2 is applied. For illustrative purposes, air is shown around the threads 3, however, this might not be the case in practice.

Fig. 1 E shows that the covering strip 4 is folded around the threads 3 and that the side sections of the covering strip 4 is encasing the threads 3. The covering strip 4 could It is seen that the threads 3 are placed at a distance from each other. This distance could vary according to the specific needs. However, a typical distance between the threads could be 5-100 mm, preferably 10-80 mm and most preferred 15-60 mm.

Fig. 2 shows an embodiment where an adhesive tape 2 has two threads 3 at the respective edges of an adhesive tape 2. The threads 3 could then be integrated in either the covering strip 4 or in the adhesive tape 2.

In another embodiment, the covering strip 4 may be made of a suitable material such as paper, plastic or fabric. Said materials may be provided so that the covering band 1 prevents a further layer such as filler, painting or wall paper from penetrating the covering band 1 and thereby preventing that the e.g. filler gets in contact with the notch of the fastening means 6.

Fig. 3 shows a covering band 1 having just one thread 3.

In another embodiment, the covering band may have one or more threads 3, and as shown in Fig. 4 the covering band could have three threads 3.

Fig. 5A and 5B show two gypsum boards 5, mounted with fastening means 6 such as screws. To prevent filling material from getting in contact with the fastening means 6, a covering band 1 (not visible) having an adhesive layer 2 (not shown) with the threads 3 has been applied before a further layer 7 of filler is applied.

Fig. 5A shows that the threads 3 have been partly pulled back and thereby the threads 3 have been cutting through the covering strip 4, and the further layer 7 of filler and thus two slits 8 are cut. This way, a strip 9 consisting of the further layer 7, in this case only filler, and a part of the covering strip 4 are created. The further layer 7 could be filler, wall paper and similar as well as paint. Having created the strip 9 it is only a matter of removing this strip 9 in order to access the fastening means 6.

Figure 5B shows that the strip 9 (not shown) is peeled away and it is possible to access the fastening means 6. Obviously, both pulling back the threads 3 and peeling the strip 9 is in practice typically carried out in the full length of the covering band 1. However, for illustrative purposes, Fig. 5A and 5B only show a small section of a strip 9 to be removed.

The fastening means 6 are free of filler because they have been protected against penetration of filler by the covering strip 4. Thereby, it is possible to unscrew the fastening means 6 and it is possible to gently to dismount the entire undamaged gypsum boards in order to re-use them.

In a preferred embodiment, the adhesive tape 2 may be a masking tape. It could also be gaffer tape, electrical tape or the like. These tapes are suitable and strong enough to be attached to the gypsum boards 5.

After attaching the covering band 1 to the gypsum boards 5, a further layer 7 such as filler, glass tissue or wall paper and painting is usually provided. Furthermore, as shown in Fig. 1A, 2, 3 and 4 an end part of the threads 3 is protruding from the covering strip 4. This end is kept protruding in order for the worker to find the covering band 1 easily and to get a firm grip of the threads 3. These ends could be hidden behind mouldings, foot panels etc. or if no such finish is present, be pushed around the edge of the gypsum boards. Gripping the threads 3 could be carried out by means of a pair of pliers or other instruments or just by hand (not shown).

The threads 3 according to the invention may be made of plastic or metal, such as steel, copper and the like. These materials will typically be strong enough to tear up the covering strip 4 and the further layer 7.

Fig. 7 shows an embodiment of the invention where the covering band 1 could have a mesh section 10 that allows, e.g. filler, to penetrate this specific section. It is seen that the fastening means 6 are covered by the covering strip 4 which in this embodiment is two smaller covering strips connected by the mesh, and thus the fastening means 6 and in particular the notch of the fastening means 6 will still not be filled with filler.
