Abstract

A mounting support for a construction panel, comprising a mounting surface for receiving the construction panel in a mounting plane. According to the invention, the mounting surface exhibits one or several first portions, which are covered by an adhesive for forming an adhesive joint with the construction panel when the construction panel contacts the adhesive, and one or several projecting portions, which are adapted, on the one hand, to form a support for the construction panel so that the construction panel can be moved freely back and forth in the mounting plane without causing the construction panel to contact said one or several first portions when the construction panel is pressed against the mounting surface with a force smaller than a predetermined pressing force, and, on the other hand, to be deformed or penetrate into the construction panel when the predetermined pressing force is exceeded to allow the construction panel to get in contact with said one or several first portions so that an adhesion joint is formed between the construction panel and the adhesive. The invention also relates to a method for mounting a construction panel by means of such a mounting support.

Description

The present invention relates to a mounting support for a construction panel, comprising a mounting surface for receiving the construction panel in a mounting plane.
The invention also relates to a method for mounting a construction panel by means of such a mounting support.
Today, construction panels of various materials and sizes are used to a very large extent in buildings. As used herein, construction panels refer to panels both for indoor and for outdoor use. The use of construction panels provides a smooth and, in principle, "ready" surface, i.e. a surface which requires comparatively little extra work before painting or wallpaper hanging can take place, and a tight and durable surface on external walls, respectively. Common materials for construction panels are plaster, MDF (Medium Density Fibre), OSB (Orientated Strand Board), chips, wood particles, composite, cement and glass fibres. Construction panels are used in floor, wall and ceiling constructions. The support upon which the construction panels are typically mounted can be studs of steel or wood, or a combination of these, but also a wall of concrete, or a plastered surface, or the like, can be subjected to covering with construction panels.
A common use of construction panels is in so called light building, where a framework of wood or steel studs forms a support for the construction panels. Wall frameworks are formed by horizontal top and bottom joists (rails), between which vertical studs are mounted at a mutual distance of 450-600 mm. Frameworks for ceilings and floors are formed in a similar way. After that, the construction panels are mounted on this framework by screwing the construction panels to the studs.
Commonly occurring construction panels are of plaster and have a width of 900-1200 mm and a length of 2400-2500 mm. It takes about 50 screws to install such a construction panel. Screw attachment of plaster panels is time-consuming and work-intensive. The screw heads must be drawn so far into the construction panel that they do not leave a bump on the panel surface, but the smoothness thereof must be possible to restore by filling screw head depressions and panel joints. Here, there is a risk that the screw thread crushes the plaster material, which will jeopardize a cohesive force acting on the construction panel or construction panels.
It can be mentioned that, as a consequence of the monotonous and repetitive work operations during screwing, just 2-3 % of the installers working daily with wall installation are able to work until retirement. A construction panel installer can install about 7 construction panels an hour. Each panel is screwed with about 50 screws. This means that the installer performs about 350 monotonous work operations each hour, resulting in 2800 work operations per working day. Therefore, repetitive strain injuries to shoulders, neck and back are common among installers. It is also common that installers get white fingers, caused by vibrations from screw driving machines.
There have been attempts to use double-stick tape for installation of construction panels. The tape method, however, has the great disadvantage that the construction panels cannot be fine-adjusted during the mounting. When a construction panel has been attached to the support by means of the double-stick tape, its position cannot, as a rule, be adjusted, which is a problem if the construction panel does not end up in exactly the correct position from the start. It has also been found that a tape joint is not sufficiently durable over time, for which reason taping is not applied for installation of construction panels to any considerable extent.
Recently, one has also started to combine the screw joints with glue joints, wherein the number of screws used for the installation has decreased. This development has primarily taken place in order to facilitate for the installers. Screws are still needed, however, to retain the construction panel in position while the glue used cures.
WO 2008/026982 A1 discloses a magnetic ruler, which can be used instead of screws for retaining the construction panel in position while the glue used hardens. This method functions very well, but has the disadvantage that a relatively large number of magnetic rulers are required if a large number of construction panels are to be installed simultaneously.
The object of the present invention is to solve these problems and to produce a mounting support, and a method in connection with such a support, enabling a simple, quick and safe installation of construction panels.
The mounting support according to the invention is characterized in that the mounting surface exhibits:

one or several first portions, which are covered by an adhesive for forming an adhesive joint with the construction panel when the construction panel contacts the adhesive; and
one or several projecting portions which, on the one hand, are adapted to form a support for the construction panel, so that the construction panel can be moved freely back and forth in the mounting plane without causing the construction panel to contact said one or several first portions when the construction panel is pressed against the mounting surface with a force smaller than a predetermined pressing force, and, on the other hand, to be deformed or penetrate into the construction panel when the predetermined pressing force is exceeded to allow the construction panel to get in contact with said one or several first portions so that an adhesion joint is formed between the construction panel and the adhesive.

In the following, the invention will be described more closely with reference to accompanying drawings.

Figure 1 shows a mounting support in the form of a vertical steel stud 1, which exhibits a U-shaped cross-section and a substantially planar surface 2. This type of steel stud is previously known per se and is frequently used when installing construction panels, wherein the construction panels are screwed to the surface 2. Before a mounting method according to the invention is implemented, however, the stud should be prepared such that it comprises a mounting surface exhibiting, on the one hand, one or several first portions, which are covered by a binding agent or adhesive for forming an adhesive joint with the construction panel when the construction panel contacts the adhesive, and, on the other hand, one or several projecting portions for forming resilient spacing elements for the construction panel. The functions of these portions will be described in the following.
In the embodiment of the invention that is illustrated in Figures 1-10, this mounting surface is achieved by means of an elongated profile 3, shown more closely in Figure 11. The profile 3 has preferably been formed by extrusion of a polymer material, e.g. EPDM, silicone or any other form of synthetic rubber or polymer. The profile 3 exhibits a back side 4 and a front side 5. An adhesive 6, in the form of a double-stick tape, is applied to the back side 4. Thereby, the tape 6 covers substantially the entire back side 4 of the profile 3. An adhesive 7, in the form of a double-stick tape, is also applied to the front side 5. In contrast to the tape 6 of the back side 4, the tape 7 of the front side 5 covers only about 2/3 of the front side 5 of the profile 3. Preferably, protective layers, e.g. protective tapes, are disposed on top of the adhesives 6 and 7.
The profile 3 exhibits a projecting portion 8, which projects a predetermined distance from the front side 5 of the profile 3, from the third of the front side 5 that is not covered by the tape 7. This distance is such that it exceeds the thickness of the tape 7. In other words, the portion 8 projects beyond the tape 7. In the embodiment shown in Figure 11, the portion 8 preferably projects about 1-30 mm, more preferably about 2-10 mm and most preferably about 2-3 mm beyond the tape 7.
In order to form a mounting support according to the invention, any protective layer is first removed from the tape 6, after which the profile 3 is attached to the surface 2 of the stud 1 by means of the tape 6, so that the profile 3 covers a part of the surface 2. Preferably, the profile 3 is attached to the free long side 9 of the surface 2, as is shown in Figure 2, wherein the surface 2 remains uncovered or free at the opposite long side 10 of the stud 1. In the shown embodiment, the profile 3 has a width that is about 1/3 of the width of the surface 2, whereby about 2/3 of the surface 2 remains free. Accordingly, the stud 1 with mounted profile 3 forms a mounting support or mounting frame 11, which exhibits a mounting surface 12 for interaction with the construction panel.
The mounting surface 12 exhibits a first portion 14, formed by the tape-covered portion of the profile 3, i.e. the part that is covered by the tape 7. The mounting surface 12 further exhibits a second portion 13, which is formed by said free portion of the surface 2. Finally, the mounting surface 12 exhibits a third portion 15, which is formed by the projecting portion 8 of the profile 3 and which thus projects above the rest of the mounting surface 12.
In order to mount a construction panel to the mounting support 11, an installer initially applies a glue string 16 onto the second portion 13 of the mounting surface 12, as is shown in Figures 5 and 6. Accordingly, the second portion 13 is adapted to form a glue-receiving portion of the mounting surface 12. The thickness of the applied glue string 16 should have a thickness dimension in the perpendicular direction of the surface 2 that exceeds the total thickness dimension of the tape 7 and the profile 3 at the first portion 14, but which is smaller than the thickness dimension of the projecting portion 15. In other words, the glue 16 should project above the level of the tape 7, but not beyond the level of the projecting portion 15, as seen in the perpendicular direction of the mounting plane, i.e. in the direction that is perpendicular to the plane in which the construction panel is to be installed.
Thereafter, the installer removes any protective layer from the tape 7, after which the installer places the construction panel 17 against the mounting support 11, so that the inward side of the construction panel 17 is caused to abut against the projecting portion 15, as is shown in Figures 7 and 8, and preferably also against the projecting portion of one or several adjacent mounting supports, which are not shown. Each projecting portion 15 is sufficiently form-stable to absorb the load from the construction panel 17 without any appreciable deformation, which load is caused by the installer pressing the construction panel 17 against the mounting support 11 with a relatively moderate force, which however is sufficient to ensure that the contact of the construction panel 17 with the projecting portion 15 is maintained. In this position, the projecting portion 15 ensures that the construction panel 17 contacts neither the glue 16 nor the tape 7, and the installer can easily position the construction panel 17 in the desired position by freely moving the construction panel back and forth in the mounting plane while keeping it supported on the projecting portion 15.
When the installer has positioned the construction panel 17 in the desired position, the installer increases the pressing force on the construction panel 17, whereby the load on the projecting portion 15 increases until the projecting portion 15 fails and allows the back side of the construction panel 17 to contact first the glue 16 and then the tape 7. Accordingly, the projecting portion 15 is adapted to be elastically or plastically deformed when a predetermined load on the portion 15 is exceeded, which predetermined load is greater than the relatively small load resulting from the pressing force required to enable the installer to retain the construction panel 17 in contact with the projecting portions 15, but which is smaller than the relatively large load resulting from the maximum pressing force with which an installer is capable of pressing the construction panel 17 against the mounting support 11. In other words, the projecting portion 15 is adapted to prevent the construction panel 17 from getting in contact with said first and second portions 14, 13 when the construction panel 17 is pressed against the mounting surface 12 with a force smaller than a predetermined pressing force, but is also adapted to be deformed when the predetermined pressing force is exceeded so that the construction panel 17 gets in contact with said first and second portions 14, 13.
When the construction panel 17 contacts the tape 7, an adhesion joint is formed immediately between the construction panel 17 and the tape 7, said adhesion joint retaining the construction panel 17 in contact with the glue 16 also when the installer releases the grip of the construction panel 17. Accordingly, the adhesion joint should be sufficiently strong to resist and overcome, on the one hand, the force of gravity acting on the construction panel 17, and, on the other hand, the return force, if any, with which the portion 15 acts on the construction panel 17, which return force can originate from the elasticity, if any, of the projecting portion 15. Thereafter, the adhesion joint retains the construction panel 17 in contact with the glue 16 while the glue 16 cures and until a glue joint has been formed between the construction panel 17 and the mounting support 11. Accordingly, the adhesion joint should be sufficiently durable over time to keep the construction panel 17 in the desired position until the glue joint has developed completely.
Accordingly, the projecting portion 15 is adapted, on the one hand, to be spacing in the positioning phase, i.e. when the construction panel 17 is positioned, and, on the other hand, to be resilient in the attachment phase, i.e. when the construction panel 17 is pressed against the mounting support 11 to be attached thereto.
It will be appreciated that the first portion 14, as seen in the perpendicular direction of the mounting plane, should be level with or project beyond the second portion 13 to allow the construction panel 17 to be brought in contact with the adhesive 7. It will also be appreciated that the distance between the second portion 13 and the first portion 14, as seen in the perpendicular direction of the mounting plane, will determine the thickness of the glue joint. Preferably, the first portion 14 should not project beyond the second portion 13 by more than 1-2 mm, as seen in the perpendicular direction of the mounting plane, which ensures that the glue joint obtains a thickness that precisely does not exceed about 1-2 mm. Since an applied glue string normally has a thickness of about 2-5 mm, this simultaneously ensures that the construction panel 17 contacts the glue 16 before the construction panel contacts the tape 7.
It will also be appreciated that the construction panel 17 should not contact the tape 7 before the construction panel 17 is in the correct position, since an adhesion joint established between the construction panel 17 and the tape 7 is very difficult to break. Accordingly, the distance between the first portion 14 and the projecting portion 15, as seen in the perpendicular direction of the mounting plane, should be sufficient to avoid premature, unintentional contact between the construction panel 17 and the tape 7. At the same time, the projecting portion 15 should not project too far beyond the tape 7, since it may be difficult in that case to compress the portion 15 during the attachment phase. To prevent the construction panel 17 from getting in contact with the tape 7 during the positioning phase, it is in principle sufficient that the projecting portion 15 projects only a little beyond the tape 7, but trials have shown that the projecting portion 15, as seen in the perpendicular direction of the mounting plane, should project at least about 1-2 mm, more preferably at least about 2-3 mm, beyond the first portion 14 to prevent the construction panel 17 from attaching to the tape unintentionally before the construction panel 17 is in the correct position. Trials have also shown that, in the shown embodiment, the projecting portion 15 should not project beyond the first portion 14 by more than about 30 mm, and more preferably by no more than about 10 mm, to allow the portion 15 to be compressed or pressed together during the attachment phase, i.e. when the construction panel 17 is attached to the tape 7. Accordingly, it is preferred that the projecting portion 15, as seen in the perpendicular direction of the mounting plane, projects about 1-30 mm, more preferably about 2-10 mm, and most preferably about 2-3 mm beyond the first portion 14. It will be appreciated, however, that the principle of the invention is not dependent on these values, but that other values may be suitable, e.g. depending on the material used in the projecting portion and the flexibility and size of the construction panel, as long as the projecting portion 15 ensures that the construction panel 17 does not get in contact with the first portion 14 during the positioning phase, but allows the construction panel to be brought in contact with the first portion 14 during the attachment phase.
In order to prevent the glue 16 from contaminating the first portion 14 during the installation and thereby reducing the adhesiveness of the adhesive 7, it is preferred that some type of obstacle or barrier is disposed between the second portion 13 and the first portion 14. In the shown embodiment, this obstacle is constituted by the projecting portion 15, which effectively prevents glue from unintentionally ending up on the tape 7 and ruining or impairing its adhesiveness.
In spite of the fact that construction panels are relatively stiff, they can bend somewhat under load. This means that a construction panel, resting on the projecting portion 15, runs the risk of contacting the adhesive 7 if the distance in the mounting plane between the projecting portion 15 and the first portion 14 is too large. Therefore, it is preferred that the first portion 14 is disposed near, and more preferably adjacent to the projecting portion 15. For the same reason, it is preferred that the second portion 13 is disposed near to, and more preferably adjacent to the projecting portion 15, to avoid that the construction panel smears the glue during the positioning.
In an alternative embodiment of a mounting support according to the invention, the mounting surface exhibits a first, adhesive-covered portion, but no second portion for receiving glue. In such an embodiment, the adhesive joint between the adhesive of the first portion and the construction panel forms the final joint between the construction panel and the mounting support.
In the following, an alternative method for mounting a construction panel according to the invention by means of such an alternative mounting support will be described more closely with reference to Figures 12-18.
In the alternative method, the profile 3 is mounted on the stud 1 in the same way as has been described above. Accordingly, the stud 1 and the profile 3 form a mounting support 11, which exhibits a mounting surface 12. The mounting surface 12 exhibits a first portion 14, which is formed by the tape-covered portion of the profile 3, i.e. the portion that is covered by the tape 7. The mounting surface 12 further exhibits a projecting portion 15, which is formed by the projecting portion 8 of the profile 3 (see Figure 11) and which thus projects beyond the rest of the mounting surface 12. In contrast to the previously described method, no glue is applied to the mounting support 11.
Thereafter, the installer places the construction panel 17 against the mounting support 11, so that the inward side of the construction panel 17 is caused to abut against the projecting portion 15, as is shown in the Figures 15 and 16, and preferably also against the projecting portion of one or several adjacent mounting supports, which are not shown. Thereby, each projecting portion 15 is sufficiently form-stable to absorb the load from the construction panel 17 without any appreciable deformation, which load is caused by the installer pressing the construction panel 17 against the mounting support 11 with a relatively moderate force, which however is sufficient to ensure that the contact of the construction panel 17 with the projecting portion 15 is maintained. In this position, the projecting portion 15 ensures that the construction panel 17 does not get in contact with the tape 7, and the installer can easily position the construction panel 17 in the desired position by freely moving the construction panel back and forth in the mounting plane while keeping it supported on the projecting portion 15.
When the installer has positioned the construction panel 17 in the desired position, the installer increases the pressing force on the construction panel 17, whereby the load on the projecting portion 15 increases until the projecting portion 15 fails and allows the back side of the construction panel 17 to contact the tape 7. Accordingly, the projecting portion 15 is adapted to be elastically or plastically deformed when a predetermined load on the portion 15 is exceeded, which predetermined load is greater than the relatively small load resulting from the pressing force required to enable the installer to retain the construction panel 17 in contact with the projecting portions 15, but which is smaller than the relatively large load resulting from the maximum pressing force with which an installer is capable of pressing the construction panel 17 against the mounting support 11. In other words, the projecting portion 15 is adapted to prevent the construction panel 17 from getting in contact with said first portion 14 when the construction panel 17 is pressed against the mounting surface 12 with a force smaller than a predetermined pressing force, but is also adapted to be deformed when the predetermined pressing force is exceeded so that the construction panel 17 gets in contact with the first portion 14.
When the construction panel 17 contacts the tape 7, an adhesion joint is formed immediately between the construction panel 17 and the tape 7, said adhesion joint retaining the construction panel 17 in contact with the mounting surface 12 also when the installer releases the grip of the construction panel 17. Accordingly, the adhesion joint should be sufficiently strong to resist and overcome, on the one hand, the force of gravity acting on the construction panel 17, and, on the other hand, the return force, if any, with which the portion 15 acts on the construction panel 17, which return force can originate from the elasticity, if any, of the portion 15. The adhesion joint forms the final joint between the construction panel 17 and the mounting support 11. Accordingly, the adhesion joint should be sufficiently durable over time to retain the construction panel 17 in the desired position during the expected life of the wall.
Figure 19 shows an alternative embodiment of a mounting support 18 according to the invention. The mounting support comprises a steel stud 19, which exhibits a U-shaped cross-section and has a substantially planar surface 20. The surface 20 exhibits a plurality of punched-out portions 21, which are bent so that they project at substantially right angles a predetermined distance from the surface 20. In the shown exemplary embodiment, the punched-out portions 21 are disposed along a substantially straight line. An adhesive 22, in the form of a double-stick tape, is disposed on one side of the punched-out portions 21. Preferably, a protective layer, e.g. a protective tape, is disposed on top of the adhesive 22 in order to protect the adhesive 22 before the mounting support 18 is used. On the other side of the punched-out portions 21, the surface 20 exhibits a free portion 23.
Accordingly, the stud 19 with adhesive 22 forms a mounting support, which exhibits a mounting surface 24 for interaction with the construction panel.
The mounting surface 24 exhibits a first portion 25, which is formed by the adhesive 22. The mounting surface 24 further exhibits a second portion 26, which is formed by said free portion 23 of the surface 20. Finally, the mounting surface 24 exhibits a third portion 27, which is formed by the projecting portions 21 and which thus projects above the rest of the mounting surface 24.
In order to mount a construction panel onto the mounting support 18, an installer initially applies a glue string 28 to the second portion 26 of the mounting surface 24, as is shown in Figure 19. Accordingly, the second portion 26 is adapted to form a glue-receiving portion of the mounting surface 24. The thickness of the applied glue string 28 should have a thickness dimension in the perpendicular direction of the surface 20 that exceeds the thickness dimension of the adhesive 22, but which is smaller than the projection of the projecting portions 21. In other words, the glue 28 should project above the level of the adhesive 22, but not beyond the level of the punched-out projecting portions 21, as seen in the perpendicular direction of the mounting plane, i.e. in the direction that is perpendicular to the plane in which the construction panel is to be installed.
Thereafter, the installer removes any protective layer from the adhesive 22, after which the installer places the construction panel against the mounting support 18, so that the inward side of the construction panel is caused to abut against and bear on the projecting portions 21, and preferably also against corresponding projecting portions of one or several adjacent mounting supports, which are not shown. Thereby, the projecting portions 21 are sufficiently form-stable to absorb the load from the construction panel without any appreciable deformation, which load is caused by the installer pressing the construction panel against the mounting support 18 with a relatively moderate force, which however is sufficient to ensure that the contact of the construction panel with the projecting portions 21 is maintained. In this position, the projecting portions 21 ensure that the construction panel contacts neither the glue 28 nor the adhesive 22, and the installer can easily position the construction panel in the desired position by freely moving the construction panel back and forth in the mounting plane while keeping it supported on the projecting portions 21.
When the installer has positioned the construction panel in the desired position, the installer increases the pressing force on the construction panel, whereby the load on the projecting portions 21 increases until the projecting portions 21 penetrate into the construction panel and allow the back side of the construction panel to contact first the glue 28 and then the adhesive 22. Accordingly, the projecting portions 21 are adapted to penetrate into the construction panel when a predetermined load on the portions 21 is exceeded, which predetermined load is greater than the relatively small load resulting from the pressing force required to enable the installer to retain the construction panel 17 in contact with the projecting portions 21, but which is smaller than the relatively large load resulting from the maximum pressing force with which an installer is capable of pressing the construction panel against the mounting support 18. In other words, the projecting portions 21 are adapted to prevent the construction panel from getting in contact with said first and second portions 25 and 26 during the positioning phase, i.e. when the construction panel is pressed against the mounting surface 24 with a force smaller than a predetermined pressing force, but are also adapted to penetrate into the construction panel when the predetermined pressing force is exceeded so that the construction panel gets in contact with said first and second portions 25, 26.
In order to facilitate the penetration into the construction panel, the projecting portions 21 should preferably exhibit a cutting edge. However, in order to facilitate the positioning of the construction panel, the portions 21 should preferably not exhibit any sharp points which run the risk of getting stuck in the construction panel during the positioning phase.
When the construction panel contacts the adhesive 22, an adhesion joint is formed immediately between the construction panel and the adhesive, said adhesion joint retaining the construction panel in contact with the glue 28 also when the installer releases the grip of the construction panel. Also the engagement of the projecting portions 21 with the construction panel contributes to this retaining force. The adhesion joint and the engagement of the projecting portions 21 with the construction panel then retains the construction panel in contact with the glue 28, while the glue 28 cures and until a glue joint has formed between the construction panel and the mounting support 18. Accordingly, the adhesion joint should be sufficiently durable over time to retain the construction panel in the desired position until the glue joint has developed completely.
As an alternative, the adhesive joint between the adhesive 22 and the construction panel, supported by the engagement of the projecting portions 21, can form the final joint between the construction panel and the mounting support, in which case the glue 28 can be dispensed with.
In the foregoing, the invention has been described based on a number of specific embodiments. It will be appreciated, however, that other embodiments are encompassed within the scope of the invention. For instance, it will be appreciated that the stud 1 can comprise more than one profile 3, in which case the mounting surface 12 exhibits a plurality of first portions 14, second portions 12 and projecting portions 15, respectively.
It will also be appreciated that the mounting support does not necessarily have to comprise a stud. Profiles of the above-described type can e.g. be attached to a planar concrete wall, in which case the concrete wall with mounted profiles forms a mounting support according to the invention.
It will also be appreciated that a mounting support according to the invention can be formed by attaching a double-stick tape, forming said first portion, and a space forming but resilient profile made of e.g. a suitable polymer material, forming said projecting portion, to a support, e.g. a stud or a concrete wall.
It will also be appreciated that the profile can be designed as an integrated part of a stud.
In the case when the mounting support comprises a stud, the second portion can be provided with through holes or openings which allow passage of glue to the back side of the stud when the construction panel is pressed against the mounting support, resulting in a stronger glue joint. Furthermore, the advantage is obtained that excess glue is prevented from spreading across the mounting surface in an unwanted manner.
It will also be appreciated that the projecting portion can be realized in a number of different ways. In a metal stud, projecting portions can be realized e.g. by punching out and bending outward portions of the surface 2, so that these punched-out portions can form supports in the positioning phase, but at the same time be pressed inward when the installer presses the construction panel against the surface in order to attach the construction panel to the adhesive.
It will be appreciated that the composition of the adhesive and its distribution on the mounting surface will be determined by its adhesive force and by the weight of the panel. Depending of these characteristics, the adhesive may be applied in dots or cover a longer, continuous portion of the mounting surface.
