Description:
Mounting element for mounting a unit on a wall Field of the Invention

The present invention relates to a mounting element for mounting a unit on a wall facing ambient air without creating a moisture bridge between ambient air and insula- tion.

Background of the Invention

The installation of a unit on a wall facing the ambient atmosphere is at present problematic. A present day wall with isolated facade systems comprises a load-bearing wall part with insulation which faces the ambient atmosphere (i.e. outside atmosphere). The insulation is damaged by moisture and thus the insulation must be isolated from the ambient atmosphere. This is done by applying one or more layers of plaster to the insulation. However, if a unit is to be installed in the wall facing the ambient atmos- phere, the installation may create a moisture bridge.

At present there are two possible options; an expensive option for a high weight load and an inexpensive option for a low weight load. The unit may be connected through a long metal screw to the inner wall, thus enabling moisture to travel along the metal rod, thereby causing damage to the insulation.

Although this solution has a high carrying capacity, there is a problem if the load becomes too great. The metal screw is fixated at the inner wall, while holding a unit at the wall facade thereby creating a large torque. The large torque may damage the inner wall, which is expensive to repair.

The unit may be installed using a product called "stofix spiral" from the company Sto. The product is essentially a screw for outdoor installation of units such as door bells. The product only grips the insulation of the wall resulting in a smaller carrying capacity of only 5 kg and there are still problems with moisture bridges. Thus, there is a need for a new inexpensive product enabling an easy installation of a unit without creating a moisture bridge between the ambient atmosphere and the insulation, while maintaining a large carrying capacity of 25-30 kg.

Object of the Invention

It is an object of the invention to overcome the limitations of the prior art with regards to the cost, moisture damage and easiness of installation.

Description of the Invention

An object of the invention is achieved by a mounting element for mounting a unit on a wall face. The mounting element may comprise a mounting end and an insertion end. The ends may define an insertion direction. The mounting element may comprise a flange extending in a flange plane perpendicular to the insertion direction to an outer periphery. The mounting element may further comprise a thread between the flange and the insertion end. The mounting element is to be installed on a wall before plaster is applied or more specifically installed into the insulation of a wall facade system. The insulation of the wall is exposed before the plaster is applied, thereby the insulation constitutes the wall face. The mounting element may then be screwed directly into the insulation, where the thread will grip the insulation material. Afterwards plaster may be applied to the insulation and to the flange. The plater may comprise one or more layers of plaster.

The mounting element does not engage with the load-bearing part of the wall and thus, the mounting element can be installed in the insulation of any wall with a layer of insulation.

Thus, the mounting element can be installed without the need of any metal screws or rods extending through the insulation for gripping in a wall or wood. This limits thermal bridges and moisture bridges. Furthermore, this makes the installation of the mounting element and the subsequent unit faster as the installation process is simpli- fied compared to the prior art.

A unit may afterwards be installed by screwing a screw into the mounting unit. The unit may be a drainpipe or a board or any other unit which may be installed on a wall facade system.

Thus, the mounting element enables easy installation of drain pipes or a board or any other unit.

Recent tests have surprisingly shown that the connection between the thread and the insulation and the connection between the flange and the plaster is strong enough to have a carrying capacity of up to 100 kg.

The tests proved that the connection between the thread and the insulation and the connection between the flange and the plaster was strong enough to resist a pull in the opposite direction relative to the insertion direction, which pull was equivalent to 200 kg.

The test proved that the mounting element was able withstand a twisting force equivalent to 110 kg.

The gripping-strength of the thread increases with the extent of the thread from the axis defined by the insertion direction.

The load-carrying part of the mounting element according to the invention is the thread and the interaction between the flange and the plaster applied to the flange and the insulation, when in intended use. This differs from the prior art mounting ele- ments, where the load is mitigated by metal screws or rods extending through the insulation to a wall i.e. the wall is the load-carrying part of the prior art mounting elements.

The application will present various embodiments for increasing the interaction be- tween the flange and the plaster and thereby increasing the carrying capacity of the mounting element without by metal screws or rods.

In an aspect of the invention, the flange may be positioned at the mounting end. Thereby, the user may easily precut a hole in the insulation complementary to the flange, making it possible for the mounting element to be inserted into the insulation such that the flange lies in plane with the insulation. This allows for easier and faster application of plaster as there is no protrusion on the exposed wall facade. In an aspect of the invention, the flange may comprise a plurality of holes adapted for engaging with a thread of a screw.

The plurality of holes makes it easier to mount a unit because the plurality of holes will guide a screw and each hole will have a radius which enables a screw with a thread to interlock with the flange, i.e. sides of the hole. The screwing is also made easier as less flange material has to be displaced as the screw can easily displace plaster.

Each hole may be circular for better gripping a screw.

Each hole may be a hollow, circular cylinder for better gripping a screw.

Another positive effect of the plurality of holes is that when plaster is applied, the plurality of holes will be filled or partially filled with plaster which increases the gripping strength of the mounting element i.e. increases the carrying capacity.

The mounting element may thus easily gain a carrying capacity of at least 25 kg.

Recent test have surprisingly shown that the mounting element can resist a pull equiv- alent of 100 kg.

Another positive effect of the plurality of holes is that the plurality of holes enables moisture to evaporate through the plurality of holes and the plaster. The build-up of moisture around the mounting element would otherwise make the mounting element visible through the one or more layers of plaster.

The combination a flange comprising a plurality of holes and one or more layers of mineral plaster has shown to especially advantageous moisture evaporation characteristics. In an embodiment, the plurality of holes of the mounting element flange may be positioned at the mounting end. This enables the mounting element to be installed as described earlier, where a hole being complementary to the flange is precut and the mounting element is inserted and plaster is applied to the face of the wall facade and flange. Tests have shown that the positioning of the flange at the mounting end while having a plurality of holes is especially strong and the moisture blocking power is high. In an aspect of the invention, the plurality of holes may be evenly distributed. When plaster is applied, the mounting element and, therefore, the flange will not be visible, and by distributing the plurality of holes evenly, the chance of finding a hole with a a screw increases. In an aspect of the invention, the plurality of holes constitutes a substantial part of the flange. Thereby, the gripping strength of the mounting element is increased as the plaster will be inserted into more holes. Furthermore, the chance of a user finding a hole with a screw when installing a unit likewise increases.

Furthermore, the evaporation of moisture is increased even further.

In an aspect of the invention, the flange has a thickness of at least 3 mm. The gripping-strength, between the flange and the screw to be screwed into the flange when installing a unit, increases with the thickness of the flange. In an aspect of the invention, the flange has a thickness of at least 4 mm. The gripping-strength, between the flange and the screw to be screwed into the flange when installing a unit, increases with the thickness of the flange.

In an aspect of the invention, the flange has a thickness of 4-6 mm. The gripping- strength, between the flange and the screw to be screwed into the flange when installing a unit, increases with the thickness of the flange.

The flange may have a thickness above 6 mm, however studies have shown that the extra gripping-strength is not utilized because the entire mounting element will be pulled out of wall facade before the flange and screw are pulled apart. So the extra material is of no real use and thus will only increase the cost of the flange.

In an embodiment of the mounting element, the flange is positioned at the mounting end and the flange has a plurality of holes and a thickness of 4-6 mm or above. Tests have shown that this particular embodiment has the most optimal gripping-strength and the highest load-bearing ability while showing good moisture blocking power and keeping material costs low. An object of the invention is achieved by a mounting element for mounting a unit on a wall face. The mounting element comprises a mounting end and an insertion end, which ends define an insertion direction. The mounting element further comprises a flange positioned between the ends, which flange comprises a plurality of legs extending in a flange plane perpendicular to the insertion direction to an outer periphery. The mounting element further comprises a thread between the flange and the insertion end.

The mounting element is to be installed on a wall before plaster is applied. The insulation of the wall is exposed before the plaster is applied. The mounting element may then be screwed directly into the insulation, where the thread will grip the insulation material. Afterwards plaster may be applied to the insulation and to the flange.

The plurality of legs creates structure gaps in the flange and when plaster is applied the structure gaps are filled with plaster and the plaster interacts with the plurality of legs. The effect of the interaction between the plaster and the plurality of legs is that the carrying capacity of the mounting element is increased.

The carrying capacity of the mounting element described above is between 25-30 kg.

After applying plaster to the wall face and the flange of the mounting element a unit may be installed on the wall face. This may be done by screwing a screw into the mounting element at the mounting end along the insertion direction. In this simple way a unit may be installed on a wall. The mounting element only interacts with the insulation and the plaster and this solves a problem present in the prior art as the prior art grips an inner wall of the wall instead of the insulation. This enables moisture in the ambient atmosphere to travel from the wall to the inner wall structure causing damage.

The unit may be a drainpipe or a board or any other unit, which may be installed on a wall.

In an embodiment the mounting element may have a body between the flange and the insertion end.

In an embodiment the mounting element may have a body having a substantially cylindrical shape between the flange and the insertion end. The substantially cylindrical shape is simple, and the user may in an easy fashion pre- drill a hole in the insulation having a similar diameter to the mounting element. This may be followed by an easier insertion of the mounting element as less insulation has to be displaced during screwing. In an embodiment the mounting element may have a substantially cylindrical shape between the flange and the mounting end.

In an aspect of the invention the flange may have an inner part from which the plurality of legs extends.

The effect of the inner part is that the stability of the mounting element increases.

Furthermore, the inner part increases the plaster gripping surface, thus the carrying capacity of the mounting element is increased even further.

The inner part may have a circular shape.

In an aspect the legs of the plurality of legs may be diamond-shaped. The effect is that the gripping surface is increased and thus the carrying capacity of the mounting element increases.

In another embodiment the plurality of legs may comprise a leg being diamond- shaped.

In a further embodiment the plurality of legs may comprise legs having different shapes. In an embodiment the mounting end has a recess at the mounting end extending along the insertion direction towards the insertion end adapted for a screw. This will ease the installation as less material has to be displaced by the screw.

In an embodiment the mounting end is adapted to interact with a screwdriver or an alien key or any other tool for screwing in the mounting element.

In an aspect of the invention the mounting end may be a protrusion extending from the flange. The protrusion enables the user to apply plaster without having to worry about not to apply plaster onto the mounting end, which may be adapted to a screw and/or a screw driver and/or alien key.

Furthermore, the plaster will typically have a thickness comparable to the extent of protrusion. As the thickness of the plaster increases the moisture blocking power increases.

In an aspect the insertion end may be pointed. The effect of the pointed end is that the force needed to insert the mounting element into the insulation is decreased as the pointed end assist in the displacement of insulation.

In an aspect the mounting element may be a monolith. The effect of the mounting element being a monolith is that cost of production is lowered and handling is increased. In an embodiment the mounting element may be two-part, where first part is the flange and the second part is the insertion end, thread and mounting end. The first and second part may then be locked together by locking means.

The locking means could be complementary male and female parts or complementary threads.

In an aspect the mounting element may be made of ABS (Acrylonitrile butadiene sty- rene) or a biodegradable plastic. ABS is water-resistant while having the necessary strength for holding a unit on a wall.

Furthermore, ABS enables the mounting element to be extruded as a monolith. Furthermore, ABS and plaster create a stable interface, which does not crack over time, thereby preventing moisture from reaching the insulation.

In an embodiment the ABS may be recycled ABS. In an aspect the mounting element may be made of a biodegradable plastic. The skilled person would know which biodegradable plastic to use.

In an aspect the flange has a thickness which gradually diminishes towards the outer periphery.

The flange is thickest at a center as it needs to have a strong connection to the body of the mounting element. At the outer periphery the aim is to get a strong connection with the plaster and this is ensured by making the flange gradually thinner towards the outer periphery. An object of the invention is achieved by a wall facade system comprising one or more mounting elements installed in insulation. The wall face system may be an external wall facade system, because mounting elements allowing for structurally strong and stable installation, and that at the same time are moisture tight, are mostly needed for external wall face systems.

The wall facade system may comprise a wall with a layer of insulation. The one or more mounting elements may be installed in the layer of insulation as described in the application. One or more flanges of the one or more mounting elements may be immersed in the layer of insulation. One or more layers of plaster may be arranged on the one or more flanges and the layer of insulation. In an embodiment an inner layer of plaster may be arranged on the one or more flanges and the layer of insulation. A reinforcement mesh may be arranged on the inner layer of plaster. A second layer of plaster may be arranged on the reinforcement mesh.

The combination of a flange and the first and second layers of plaster separated by a reinforcement mesh the have shown in tests to increase the carrying capacity greatly.

Thus, the mounting element may be installed without metal screws or rods, which would otherwise form moisture and thermal bridges and complicate the installation of the mounting element and the subsequent unit on the wall facade system.

The wall face system comprising one or more mounting elements may be a prefabricated, such that the wall face system is shipped with one or more mounting elements, thereby allowing a fast and easy installation. An object of the invention is achieved by a method for installing a mounting element in a wall face, the method may comprise one or more acts of;

- an act of providing a mounting element,

- an act of pre-drilling a hole for the mounting element in insulation,

- an act of screwing the mounting element into the hole, - an act of applying plaster on the flange and the insulation.

Thereby, the mounting element may be installed in without the use of metal screws or rods extending through the insulation of the wall.

The method may comprise further one or more acts of:

- an act of applying a reinforcement mesh on the plaster,

- an act of applying plaster on the reinforcement mesh. As an example the method of installing a mounting element in a wall may be done by an act providing a mounting element. This may be followed by an act of pre-drilling a hole for the mounting element in the insulation, where the pre-drilled hole is adapted for the shape of the mounting element. This may be followed by an act screwing the mounting element into the hole. The thread interacts with the insulation. Lastly, an act of applying plaster on the flange and the insulation may be performed, which will complete the installation of the mounting element in the wall face.

This may be followed by mounting a unit such as a drainpipe on the wall by an act of attaching the drainpipe to the mounting element by screwing a screw attached to the drainpipe into the mounting end along the insertion direction. In this way the unit may be secured onto the drainpipe.

As another example, the method of installing a mounting element in a wall may be done by an act of providing a mounting element with the flange positioned at the mounting end and the flange comprising a plurality of holes. This may be followed by an act of pre-drilling a hole in the insulation for the mounting element, and the pre- drilled hole is adapted for the shape of the mounting element, such that the flange and insulation will form a common plane. This may be followed by an act screwing the mounting element into the hole. The thread interacts with the insulation. This is followed by an act of applying a first layer of plaster on the flange and the insulation. An act of applying a reinforcement mesh on the first layer of plaster is performed. Lastly, a second act of applying a second layer of plaster on the reinforcement mesh is performed. An object of the invention is achieved by the use of one or more mounting elements for mounting a unit on a wall face.

The unit may be a drain pipe or a billboard.

An object of the invention is achieved by a wall comprising an inner wall with an insulation layer in which one or more mounting elements are inserted, thereby forming a common plane with the insulation layer, which common plane has at least one layer of plaster. The wall further comprises one or more units secured to the one or more mounting elements by securing means, such as screws or the like.

The at least one layer of plaster may comprise an inner layer and an outer layer. There may be a reinforcement mesh between the inner and outer layer. The reinforcement mesh increases the overall structural stability of the mounting element in the wall.

An object of the invention is achieved by use of a wall facade system for mounting a unit.

The mounting element 10 further comprises a thread 20 between the flange 30 and the insertion end 14.

The plurality of legs 32 defines a plurality of structure gaps 40 extending in a substan- tially radial direction from the mounting end 12.

Fig. 3 illustrates a side view of a mounting element 10 before A and after B installation in a wall 78. The mounting element 10 has the same features as the disclosed mounting element 10 in the embodiment of Fig. 1.

In Fig. 3B the mounting element 10 is installed in a wall 78 comprising an inner wall 82, insulation 80 and plaster 84. The mounting element 10 is screwed into the insulation 80 before plaster 84 is applied. In this embodiment the protrusion 16 has a thickness comparable to the applied plaster 84.

Fig. 4 illustrates a side view (A) and a front view (B) of a second embodiment of the mounting element 10. The mounting element 10 comprises an insertion end 14 and a mounting end 12, the ends 12, 14 define an insertion direction 60.

The mounting element 10 further comprises a flange 30 positioned at the mounting end 12 and extending in a flange plane 62.

The wall 78 in fig. 5B comprises an inner wall 82 followed by a layer of insulation 80. An act of pre-drilling has been performed in the insulation 80 such that the flange 30 can be lowered into the insulation 80. The flange 30 and the insulation 80 thereby form a common plane face. The mounting element 10 has been screwed into the insulation 80.

Plaster 80 is applied to the common plane face. The layer of plaster 80 comprises a thin first layer onto which a reinforcement mesh is positioned this is followed by thick second layer. The first layer is thin relative to the second layer.

The skilled person would realise that the mounting element is installed in the insulation without screws or rods extending through the insulation.

Fig. 6 illustrates another method 100 for installing a mounting element 10.

The method 100 for installing a mounting element 10 in a wall 78, the method 100 may comprise one or more acts of;

- an act of providing 1 10 a mounting element 10,

- an act of pre-drilling 140 a hole in insulation 80 for the mounting element 10,

- an act of screwing 120 the mounting element 10 into the hole, and

- an act of applying 130 plaster 84 on the flange 30 and the insulation 80.

The above-mentioned acts may be followed by one or more acts of;

- an act of applying 130 a reinforcement mesh on the plaster 84,

- an act of applying 130 plaster 84 on the reinforcement mesh.

As an example an act providing 110 a mounting element 10 is performed. This is followed by an act of pre-drilling 140 a hole for the mounting element 10, which enables insertion of the mounting element 10 with a minimal deforming of the insulation 80. The hole is complementary to the mounting element.

This is followed by an act screwing 120 the mounting element 10 into the hole. Lastly, an act of applying 130 plaster 84 on the flange 30 and the insulation may be performed, which will complete the installation of the mounting element 10 in the wall 78.

There may be a further act of applying 130 a reinforcement mesh on the plaster 84 followed by applying plaster 84 on the reinforcement mesh. The two layers of plaster having a reinforcement mesh in-between has shown in test to increase overall struc- tural strength of the mounting element 10 inserted/screwed into the insulation 80.

This may be followed by mounting a unit such as a drainpipe on the wall 78 by an act of attaching the drainpipe to the mounting element 10 by screwing a screw attached to the drainpipe into the mounting end 12 along the insertion direction 60.
