Description
Title: Fastening assembly for fastening a plurality of facade panels to the face of a building
The present disclosure, in general, relates to a fastening assembly for fastening a plurality of facade panels to the face of a building, and more in particular, to a fastening assembly for fastening a plurality of fagade panels to the face of a building, wherein the facade panels are spaced apart from each other by a minimal spacing d, and the facade panels comprise one or more solar panels.
Facade panels or prefabricated facade panels form part of facade cladding systems. Facade claddings form the outer skin of a building. It not only adds protection of the building against environmental conditions, but maybe even more importantly, it largely determines the appearance of, and thereby adds to the character of the building. Facade panels may be considered one of the most important distinguishing aspects of a building.
In addition to various other reasons, this is what makes facade panels particularly popular with architects because they can easily give the building a high- quality aesthetic character.
Tile based facade panels are becoming increasingly popular since they can provide the high-quality aesthetic character and are easy to install and can be fabricated prior to being attached. To this end, the cladding system consist of a fastening assembly elongated profiles or other structural elements to which the panels can be attached.
Within architecture, sustainability is also becoming increasingly popular as a demand for more eco-friendly approach to modern day building encompasses most aspects of the construction process. This not only includes the choice and footprint of building materials but also the implementation of modern, eco-friendly utilities such as heating, cooling, ventilation and electricity. Partly because of this,
solar panels have already taken an important position in the transition from traditional construction and architecture towards a more future-oriented sustainable construction.
Traditionally, solar panels are used on roofs because they are generally seen as elements that detract from the aesthetic character of the building. However, the increase in energy demand often exceeds the capacity that the solar panels on the roof of the building can provide. Especially in high-rise buildings and populated areas, the roof space is insufficient to support sufficient solar panels, and sometimes not very suitable for installing (large numbers of) solar panels, which even further increase the need for alternative solar panel placements.
As such, facade panels having integrated solar panels are becoming increasingly popular. When compared to conventional fagade panels, solar panel comprising fagade panels are more expensive and technically complex. It is therefore desirable to be able to replace single facade panels without having to detach plural panels, in order to ease maintenance and replacement.
To this end, the fastening assembly for mounting the facade panels should be configured to allow such detaching of a single panel. Despite the fact that the panels must be detachable, they must be properly attached, which means that they are sufficiently robustly attached to the building that they remain attached even under extreme weather conditions. Robust mounting often results in a non-appealing and non-aesthetic outcome that cannot bear the approval of the architect.
Accordingly, there is a need for a fastening assembly for robust fastening of a plurality of facade panels to the face of a building, which are mutually spaced apart from each other by a minimal, aesthetic appealing spacing, wherein said facade panels comprise one or more solar panels, and wherein the fastening assembly is arranged for individually detaching each of said facade panels from said face of said building for ease of maintenance and replacement thereof.
The object is achieved, in a first aspect, by a fastening assembly for fastening a plurality of facade panels to the face of a building, mutually spaced apart from each other by a spacing d, wherein said facade panels comprise one or more solar panels, said assembly comprising: - a plurality of first and second fastening rails, arranged to be attached in a horizontal orientation, to said face of said building, for forming alternating parallel rows of first and second fastening rails, respectively; and said assembly, for each of said facade panels, further comprising: - a plurality of elongated supporting elements, arranged to be attached to the backside of said facade panel in a vertical orientation, each of said supporting elements, comprising a pair of: - a first attaching bracket attached to the top of said supporting element, and - a second attaching bracket attached to the bottom of said supporting element, wherein said pair of first and second attaching brackets is arranged for detachably attaching said facade panel to said face of said building; wherein said first and second attaching brackets have hook-shaped profiles comprising a rim for hooking said attaching bracket to one of said first and second fastening rail, and wherein a height h of said rim, in use, substantially corresponds to, and is at most said spacing d, and wherein said first attaching brackets further comprise clamping elements for fixing said first attaching brackets to a respective first fastening rail, and said clamping elements comprise a slot for receiving fastening means such as a screw or bolt, and wherein said first attaching brackets are arranged such that, in use, said slot is vertically aligned with said spacing d between a facade panel supported by said respective first attaching bracket and a neighbouring facade panel.
The proposed fastening assembly is arranged to support and mount several facade panels having integrated solar panels as available from the applicant of the present disclosure. The fastening assembly exhibits fastening rails, supporting elements and attaching brackets. The fastening rails are arranged to be attached in a horizontal orientation and are mounted to the face of the building to which the facade cladding is to be mounted. These fastening rails are provided or attached in parallel rows wherein the top row is formed by one or multiple first fastening rails, followed by a second row, parallel to the first, being formed by one or multiple second fastening rails, and below that row again a parallel row of first fastening rails, and so on. As such the first and second fastening rails are attached, for example by screws, bolts or nails or other type of fastening means, to the face of the building and distributed over the to-be-cladded-surface of the building.
The facade panels are attached to these rails in a pair-wise-manner, meaning that each facade panel has two, three or more supporting elements attached to the backside of said facade panel in a vertical orientation. The supporting elements are elongated members, bars, or rails which preferably extend substantially from the top to the bottom of the backside of the facade panel. The supporting elements may be attached to the panel by fastening means such as screws, bolts, nails or other type of fastening means, but are preferably attached by glue as the backside of facade panels with solar panels is typically formed by a glass panel, e.g. a three layered glass sandwich panel and wherein the glue may also in any example comprise a tape which is provided with glue on both sides to withstand prescribed wind-endurance requirements such as wind-class 2.
Each supporting element comprises a first and a second attaching bracket, wherein the first attaching bracket is attached to the top of said supporting element, and the second attaching bracket attached to the bottom of said supporting element, respectively.
With the these attaching brackets the facade panel can be detachably attached to the face of the building as they have hook-shaped profiles to mate in shape with a top section of the horizontally orientated fastening rails. The brackets can thus be hooked onto the fastening rail, for which the brackets are provided with a rim or a formed such that they exhibit a rim shaped element, which in use is directed downwardly to hook onto said fastening rail.
The rim of the brackets extends to such a degree or has a height A that is sufficient to withstand horizontal displacement of the facade panel with respect to the fastening rails or face of the building. 5 The inventors had the insight that a large height of the rim would increase robustness as the force required to de-hook the facade panel from the fastening rails would significantly increase, but that an increase in rim height would also require an increase the spacing between two adjacent facade panels, for the panels to be detached individually.
Decreasing the rim height would allow smaller spacings between the panels, but would undesirably increase the chance of the panels to come loose in extreme weather conditions and thus impair robustness. According to the present disclosure the rim height A thus substantially corresponds to the spacing d between the panels, to allow individual detaching but at a maximum clamping force and thus maximum robustness.
To further aid robustness, at least the first attaching brackets, but preferably both the first and second attaching brackets, on the top of the facade panel and thus preferably also on the bottom thereof, are provided with clamping elements for fixing the first attaching brackets to a respective first fastening rail. These clamping elements may be defined as segments of the first fastening rail, which are formed as one or several strips which in use are in a plane parallel to the face of the building.
These clamping elements or strip(s) are provided with a slot or several slots for receiving fastening means such as a bolt, nail or preferably a screw.
The facade panels are thus supported mostly by the attaching brackets, which carry all or at least most of the weight of the relatively heavy (due to the integrated solar panels) facade panels. As the attaching brackets hook to the fastening rail, their horizontal movement of the panels is fixed. With the clamping elements the horizontal movement is even further fixed and thus the clamping force in horizontal direction if further increased, which adds to the total robustness. The clamping elements however also block or fix the vertical movement of the panels which thus block or prevent the brackets from coming loose from the rail, e.g. under extreme winds or other heavy weather conditions.
To be able to the allow individual detaching of a single fagade panel the fastening means by which the brackets are fixed, should be accessible for a tool such as a screw driver, Allen wrench or the like. To this end, the first attaching brackets, e.g. by placement of the horizontal elongated fastening rails, are arranged such that, in use, the slot is vertically aligned with the spacing d between the facade panel supported by the respective first attaching bracket and a neighbouring fagade panel such as the facade panel there above. This way the spacing between the facade panels can be kept to a minimum, but the individual detaching of panels is maintained, whereas the proposed fastening assembly provides good overall robustness due to high camping force of the rail and attaching brackets aided by the clamping elements.
In an example, the spacing d between two adjacent fagade panels is between 7 mm and 20 mm, preferably between 9 mm and 15 mm, more preferably between 10 and 12 mm, and most preferably 10 mm.
In an example, the height A of said rim is between 7 mm and 20 mm, preferably between 9 mm and 15 mm, more preferably between 10 and 12 mm, and most preferably 10 mm.
In an example, said elongated supporting elements are glued to the back side of said facade panel.
In an example, said assembly is arranged for fastening facade panels having a height up to 1800 mm and a width up to 1200 mm, and a weight in the range of 18 to 30 kg/m?, preferably 22 to 26 kg/m?. The skilled person will appreciate that said assembly can also be arranged for fastening fagade panel having a height up to 1200 mm and a width up to 800 mm and also dimensions that are larger than 1800 mm height and 1200 mm width.
In an example, one or more of said first and second fastening rails, elongated supporting elements and said first and second attaching brackets are made of a metal, preferably aluminium, i.e. classified as EN-AW 6060-T66.
In an example, said neighbouring facade panel is a facade panel attached above said facade panel.
In an example, said rim extends in a plane formed parallel to said face of said building.
In an example, said rim extends in at an inclined angle a to a plane formed parallel to said face of said building for directing said fagade panel towards said face of said building.

In an example, said first fastening rails and said second fastening rails have correspondingly shaped profiles.
In an example, said first attaching bracket and said second attaching bracket have correspondingly shaped profiles.
In a second aspect, there is provided a facade panel for fastening to the face of a building for creating a wall of facade panels, mutually spaced apart from each other by a spacing d, wherein said facade panel comprises one or more solar panels and further comprising: - a plurality of elongated supporting elements attached to the backside of said facade panel in a vertical orientation, each of said supporting elements, comprising a pair of: - a first attaching bracket attached to the top of said supporting element, and
