FAÇADE CLADDING AND A METHOD FOR APPLYING IT TO A FAÇADE

TECHNICAL DOMAIN

The present invention relates to a mosaic facade cladding and a method of applying it to a facade.

STATE OF THE ART

Facade coverings consisting of ceramic tiles such as mosaics are known in the art. A mosaic is often glued to floors and to walls inside buildings, typically in swimming pools. A cement-based adhesive is often used for bonding the mosaic. Problems with porous, cement-based adhesives are known: they absorb water and are therefore easily stained. In addition, cement-based adhesives have limited resistance to freeze-thaw cycles. However, a mosaic covering on the exterior facade of a building, consisting of a large number of floors, is subject to strong variations in temperature. For example, for the moderate maritime climate in Belgium, variations in temperature from -20 ° C to + 60 ° C on façade surfaces at tens of meters high are no exception. Moreover, these often large facade surfaces are usually composed of materials with negligible (differences in) thermal expansion coefficients. A known consequence of this is rapid degradation, in the form of loosening of the facade cladding and / or the development of cracks at the seams in the underlying facade. A further difficulty is that many (cement-based) tile adhesives contain a coarse, sandy component, which scratches the mosaic. Mosaic tiles made of transparent glass are extra sensitive to this.

The present invention aims to find a solution to at least some of the aforementioned Problems.

BE2016 / 5925

SUMMARY OF THE INVENTION

The present invention relates to a method for applying a facade cladding to a facade, according to claim 1, and a facade provided with a facade cladding, according to claim 15.

In a first aspect, the invention relates to a method for applying to a facade of a facade cladding comprising ceramic tiles, comprising in order of enumeration:

the provision of a metal supporting structure on the facade, the fixing of cement fiber plates to the supporting structure, the application of a primer on the cement fiber plates and the gluing of the ceramic tiles on this primer.

In particular, prior to applying the base coat, the cement fiber boards are wetted to a moisture content of at least 60% wme. WME stands for 'Wood Moisture Eguivalent'. This value can be measured with any Protimeter, for example using the General Electrics BLD5085 Protimeter. The wetting of the cement fiber boards has consequences for the bonding value of the mosaic, as measured by bonding tests: the average bonding value of the mosaic on the cement fiber boards, immediately after curing, exceeded 0.50 N / mm ² . Only after a load comprising at least 80 consecutive heat-rain cycles, at least 5 consecutive heat-cold cycles and at least 30 consecutive freeze-thaw cycles, the average adhesion value had dropped significantly. It was then between 0.40 N / mm ² and 0.50 N / mm ² . The specifications of said cycles are described in the detailed description. For non-wetted cement fiber boards, on the other hand, the average adhesion value immediately after curing was below 0.30 N / mm ² . However, after the same load as above, the average adhesion value rose to a value between 0.40 N / mm ² and 0.50 N / mm ² , similar to that for wetted cement fiber boards. It is nevertheless advantageous to wet the cement fiber plates: the corresponding adhesion value will then always be at least 0.40 N / mm ² . As a result, much higher demands can be made on such facade cladding, which is typically necessary for curved or twisted exterior walls of buildings consisting of a large number of floors.

In a second aspect, the invention relates to a facade with facade cladding, applied according to the above method and comprising a metal

BE2016 / 5925 supporting structure, cement fiber boards, a reinforced or reinforced base layer and ceramic tiles, glued to the latter base layer. In particular, the average adhesion value of the mosaic to the cement fiber sheet immediately after curing is at least 0.50 N / mm ² . After a further load on the mosaic, comprising at least 80 consecutive heat-rain cycles, at least 5 consecutive heat-cold cycles and at least 30 consecutive freeze-thaw cycles, this value does not drop below 0.40 N / mm ² . As a result, much higher demands can be made on such facade cladding, which is typically necessary for curved or twisted exterior walls of buildings consisting of a large number of floors.

DETAILED DESCRIPTION OF THE INVENTION

The present invention relates to a mosaic facade cladding and a method of applying it to a facade.

Unless otherwise defined, all terms used in the description of the invention, including technical, scientific and mathematical terms, have the meaning as they are commonly understood by those skilled in the art of the invention. For a better assessment of the description of the invention, some terms are explained explicitly.

When around or around this document is used with a measurable quantity, a parameter, a duration or moment, and the like, variations of +/- 20% or less, preferably +/- 10% or less, more at preferably +/- 5% or less, even more preferably +/- 1% or less, and even more preferably +/- 0.1% or less than and of the quoted value, insofar as such variations apply in the described invention. However, it is necessary here

The terms include, comprising, consisting of, comprising, containing, containing, containing, controlling, controlling, contents, containing are synonyms and are inclusive or open terms which indicate the presence of what follows, and which do not exclude the presence or inhibiting other components, features, elements, members, steps, known from or described in the prior art.

In a first aspect, the invention relates to a method for applying to a facade of an (exterior) facade covering comprising ceramic tiles, comprising in order of enumeration:

the provision of a metal supporting structure on the facade, the fixing of cement fiber plates to the supporting structure, the application of a primer on the cement fiber plates and the gluing of the ceramic tiles on this primer.

In particular, prior to applying the base coat, the cement fiber boards are wetted to a moisture content of at least 60% wme. WME stands for 'Wood Moisture Equivalent'. This value can be measured with any Protimeter, for example using the General Electrics BLD5086 Protimeter. The wetting of the cement fiber boards has consequences for the adhesion value of the mosaic, as measured by adhesion tests: these showed that, by this wetting, an increased mutual adhesion of the different layers of which the facade cladding is built up is obtained. In a preferred form of the invention, the metal support structure comprises metal brackets and metal support profiles. A suitable bracket is, for example, a stainless steel pleated flat iron with a plurality of round holes and / or slotted holes. The pleat should be such that the bracket consists of two flat legs that enclose a right angle. More generally, a metal bracket includes two flat legs enclosing a right angle, each with a plurality of round holes and / or slotted holes. In a preferred form of the method, a series of brackets are attached to the facade to be clad, using fasteners. The first leg comes to lie flat against the facade to be clad locally and the second leg to be perpendicular to the facade to be clad locally. Non-limiting examples of fasteners in case of a concrete or masonry facade are screws with appropriate nylon or brass

BE2016 / 5925 plug or wedge bolts. In a preferred form of the present invention, holes are drilled in the facade to be clad, suitable for clamping the screws therein with plug or wedge bolts. Given the multitude of round holes and / or slotted holes in the first leg of the bracket, there is a tolerance of at least 5 mm at the position of these drilled holes. In a preferred embodiment of the method, the brackets are mounted in rows on the facade, the second flat leg of each bracket being parallel to the direction of the respective row.

In particular, the facade cladding will be applied to a facade that is either flat, curved or twisted, or consists of a shading of flat, curved and / or twisted parts. More generally, the facade as a whole, or at least the parts cited above, can then be described in good approximation by a control surface. In the context of the present invention, the term "control surface" is to be understood as a surface through which at least one line passes through each of its points, which is completely contained within the surface. Such a line is called a descriptive of the control surface. Each row of brackets on the surface of the facade to be clad is now preferably located along a descriptive of the control surface. The mutual distance between the rows, as well as the mutual distance between the stirrups within the same row, is between 100 mm and 1000 mm.

Then a trunking is fastened to the second leg of each row of brackets, using fasteners. The term "support profile" preferably denotes a straight metal profile with a U-shaped, T-shaped or other cross-section and with a plurality of round holes and / or slotted holes. In the case of a long row of brackets, one support profile comprises several such metal profiles, placed in line, possibly with an overlap of 100 mm to 1000 mm. A suitable fastener is, for example, a screw or bolt with nut. In general, the support profiles are straight metal profiles that comprise at least two mutually perpendicular, flat sides; at least the first flat side has a plurality of round holes and / or slotted holes. The first flat side is then suitable for mounting against the second flat leg of the brackets. Due to the multitude of round holes and / or slotted holes in both the second leg of each bracket and in the first flat side of the support profile, there is a tolerance of at least 5 mm for the positioning of the brackets on the facade. The second flat side of the support profiles, after attachment to the brackets, is locally parallel to the facade surface. This second flat side is then

BE2016 / 5925 suitable for fastening cement fiber boards to the metal support structure, using fasteners. A possible fastener for this is a stainless, self-tapping metal screw with countersunk head. This is then screwed through the cement fiber board into the second flat side of the respective support profile. In a preferred form of the embodiment, the parts of the metal supporting structure made of stainless steel, aluminum and / or steel are provided with a surface treatment. The latter surface treatment can consist of a galvanized layer or a paint layer.

The cement fiber plates preferably have a thickness between 8 mm and 40 mm. In addition, they are sufficiently flexible to follow the local curvature of a curved / twisted facade surface, provided that this curvature does not exceed 0.002 mm ' ¹ in any direction in the surface. The distance between the cement fiber boards and the facade surface can be varied according to the chosen length for the second leg of the brackets. This distance is preferably between 50 mm and 450 mm, more preferably between 100 mm and 400 mm, even more preferably between 150 mm and 350 mm and even more preferably between 200 mm and 300 mm. In the most preferred situation, the distance between the cement fiber boards and the facade surface is approximately 217 mm. In a preferred form of the method, the space between the facade and the cement fiber plates is at least partly filled with an insulating filling. This preferably takes place after the brackets have been attached to the facade and prior to the mounting of the supporting profiles against the brackets. Optionally, a waterproof layer is applied on top of the insulation layer. This is particularly recommended when parts of the facade are angled upwards.

In a preferred form of the method, a joint of 3 mm to 5 mm wide is left between the cement fiber plates. This space is then filled with a filling material. These holes are also filled in as a result of any screw heads countersunk in the cement fiber board. For example, a silicone is used as a filling material.

In a preferred form of the method, the base layer is reinforced with fibers, with a reinforcement net or with a reinforcement plaster. Preferably, a reinforcement mesh or a reinforcement plaster is used in the middle of the base coat, so that the base coat consists of a bottom base coat, a reinforcement layer and a top

BE2016 / 5925 primer. In an even more preferred embodiment, the reinforcement is a meshed structure, so that the bottom base layer is continuously connected to the top base layer, through the meshes of the reinforcement or reinforcement layer. For this purpose, the base coat is applied to the cement fiber boards in three stages. In a first phase, a first primer of 1 mm to 5 mm thickness is applied, then the reinforcement mesh or the reinforcement plaster is pressed lightly into this first primer, without touching the cement fiber plates. In a third phase, a second primer is applied, on top of the applied reinforcement and with a thickness of 1 mm to 5 mm. Preferably, an overlap of 50 mm to 200 mm is provided between adjacent reinforcement nets or reinforcement plasters. The reinforcement is applied with the aim of preventing the development of cracks, in particular at the level of seams in the underlying facade or in the layer of cement fiber plates.

Once the base coat has cured or dried, the mosaic can be glued to the base coat. For gluing and / or joining the mosaic, a multi-component epoxy adhesive is used, comprising a resin component and a hardener component. The resin component includes an epoxy resin. The curing component includes an epoxy hardener. Epoxy adhesive has the advantage over standard cement-based adhesives that it is water-resistant and therefore less stained. It is also more resistant to frost thaw cycles. The epoxy adhesive can also include a color component, which allows the adhesive to be colored according to any color of, for example, the RAL color standard. Preferably, none of the components of the multi-component epoxy adhesive include sand. After all, mosaic tiles made of transparent glass are sensitive to scratches due to sand particles. Preferably, the epoxy adhesive is applied in abundance and then combed with a 4 mm notched trowel at an angle of 45 °.

The individual mosaic tiles are preferably circular or rectangular. They are glued to the base coat according to an ordered grid. The mosaic tiles are preferably glued along their visible side on a flexible plastic surface, in sets of 5 to 250 pieces. This, in a detachable manner and already according to the intended pattern. This allows an entire set of tiles to be positioned correctly in one movement. After gluing the set of mosaic tiles, the plastic surface is removed. The mosaic tiles are also made of transparent glass. The result is that the underlying layer of glue is visible. The facade can therefore be colored according to the type

BE2016 / 5925 the color component that is optionally added to the epoxy adhesive. After gluing, the mosaic tiles are grouted. Preferably, the same type of multi-component epoxy glue is used for grouting as that used for gluing. If the top of the mosaic tiles is soiled with grout, it should be cleaned within 24 hours using a detergent. Further preferably, a solution of vinegar in water is used for this purpose, with a ratio of about 118 ml of vinegar per 8 liters of water. It is preferable to clean the first time, 20 minutes after grouting.

The resulting mosaic comprises a regular grid of mosaic tiles, the area of an individual mosaic tile being preferably between 25 mm ² and 2500 mm ² and more preferably between 100 mm ² and 1000 mm ² . The use of tiles with an area of less than 25 mm ² imposes conditions on the finishing of underlying layers, in particular on the finishing of the adhesive layer. This should then be combed finer. Tiles with an area larger than 2500 mm ^{2, on} the other hand, do not allow sufficient to follow the curves of a curved or twisted facade surface, unless these tiles are elongated in shape. This is especially the case when there is a direction in the surface along which the curvature of the surface is greater than 0.002 mm ^-1 . Preferably, the mosaic tiles have a thickness between 2 mm and 20 mm, and more preferably between 4 mm and 8 mm.

In a second aspect, the invention relates to a mosaic facade cladding applied according to the above method. The facade cladding comprises a metal supporting structure, cement fiber plates, a reinforced or reinforced base layer and ceramic tiles, glued to the latter base layer. The metal support structure includes brackets and support profiles.

Immediately after curing, the average adhesion of the mosaic to the cement fiber board is between 0.50 N / mm ² and 5 N / mm ² . A period of 14 days is provided for complete curing at a temperature of 21 ° C. The average adhesion value of the mosaic to the cement fiber boards is preferably determined by conducting the adhesion test as described below.

In a first step, the bottom side of a metal tensile block is glued to the test surface. Said bottom is square, with a side of about 50 mm. An even incision is made along the edge of this underside

BE2016 / 5925 depth in the wall cladding. Preferably, this cut cuts through the mosaic tiles and / or the joints and the adhesive layer, up to the separation between the adhesive layer and the reinforced / reinforced base layer. The top of the drawing block is the point of engagement of a device capable of exerting a controlled and measurable pulling force on the drawing block. The tensile force is now systematically increased and the minimum force leading to adhesion failure is determined. The adhesion value of the mosaic to the cement fiber board, at this position of the test surface, is now the ratio of the measured force value to the size of the area of the bottom of the drawing block, being approximately 2500 mm ² .

The cladding is now such that it does not suffer any visible damage when subjected to at least 80 consecutive heat-rain cycles, at least 5 consecutive heat-cold cycles and at least 30 consecutive freeze-thaw cycles, in the order specified. The heat-rain cycles, the heat-cold cycles and the freeze-thaw cycles are preferably performed as described below. Room temperature means a temperature of about 20 ° C. Preferably, prior to the series of freeze-thaw cycles, the test samples are sprayed with water at a temperature of about 15 ° C, at a flow rate of about 1.5 liters per minute per square meter and for at least 8 hours, followed by immediate and subsequent starts with the first of the series of freeze-thaw cycles.

A heat-rain cycle consists of the following 4, subsequent steps:

heating the test sample from room temperature to about 70 ° C, in about 1 hour, maintaining the temperature of the test sample and its environment at about 70 ° C, for about 2 hours, spraying the test sample with room temperature water, at a flow rate of about 1.5 liters per minute per Square meter and for about 1 hour and draining the test sample at room temperature and for about 2 hours.

A heat-cold cycle consists of the following 5, subsequent steps:

place the test sample in an environment of at least 50% relative humidity and at room temperature for 48 hours,

BE2016 / 5925 heat the test sample environment to about 50 ° C, with a relative humidity of up to 30%, in about 1 hour, keep the test sample in the environment just described for 7 hours, at constant temperature and constant relative humidity, the environment cool from the test sample to about -20 ° C, in about 2 hours, and keep the test sample in the environment just described for about 14 hours, at constant temperature and constant relative humidity.

A freeze-thaw cycle includes the following 4 consecutive steps:

cool the environment of the test sample to about -20 ° C, in about 2 hours, keep the test sample in the environment just described for about 4 hours, at constant temperature, warm up the environment of the test sample to about 20 ° C, in about 1 hour, and spraying the test sample with water at 15 ° C, at a flow rate of about 1.5 liters per minute per Square meter and for about 1 hour.

In addition, the facade cladding is such that, after subjection to at least 80 consecutive heat-rain cycles, at least 5 consecutive heat-cold cycles and at least 30 consecutive freeze-thaw cycles, the average adhesion of the mosaic to the cement fiber board is between 0.40 N / mm ² and 4 N / mm ² . The adhesion value of the mosaic to the cement fiber board was measured as described above.

Example and figure:

Below, the adhesion tests are presented as performed, including the results. The various aspects are further elucidated by means of Figure 1, without the invention being limited to this figure. Figure 1 shows a cross-section of an embodiment of a mosaic facade cladding, illustrating the adhesion test.

BE2016 / 5925

First two sets of samples of the facade with facade cladding were produced, called samples I and samples II. The following steps were followed, in accordance with the detailed description above:

drilling drill holes 2 in a vertical concrete surface 1, attaching stainless steel brackets 4 to the concrete surface 1 by means of wedge bolts 3, tightened in drill holes 2, attaching aluminum support profiles 5 to the brackets 4 by means of a bolt with nut, attaching the cement fiber plates 6 against aluminum support profiles 5 by means of self-tapping metal screws 7 with countersunk head, tightened in the aluminum profiles 5, filling the joints between adjacent cement fiber plates 6, as well as any holes 8 resulting from the attachment by means of self-tapping metal screws 7 with countersunk head, moistening the cement fiber plates 6 contained in samples I, at a humidity of at least 60% wme; the cement fiber plates 6 of samples II, on the other hand, are not wetted, the application of a primer 9 to cement fiber plates 6, consisting of a bottom primer 10, a reinforcement or reinforcement layer 11 and an upper primer 12, of gluing circular mosaic tiles 14, manufactured of transparent glass, on the base coat 9, about 7 days after applying the base coat 9 and by means of a layer 13 of multi-component epoxy glue, filling the joints 15 between the mosaic tiles 14, using the same multi-component epoxy glue and 1 day after bonding the mosaic 14 and cleaning the joined mosaic.

Thus, in samples I, the cement fiber boards were wetted prior to applying the primer. This was not the case with samples II.

To determine the adhesion of the mosaic to the cement fiber board 6, the square bottom (50x50 mm) of a drawing block 17 was glued to the mosaic, both on samples I and samples II. This, after complete curing of the mosaic facade cladding. Preferably, a cure period of 14 days at 21 ° C was provided for this. An incision 16 was then made along the edge of the drawing block 17 in the mosaic. The incision 16 had a uniform

BE2016 / 5925 depth and cut the mosaic tiles 14 and / or the joints 15 and the adhesive layer 13, up to the interface between the adhesive layer and the reinforced / reinforced base layer

9.

On the one hand, the adhesion values of the mosaic to the cement fiber board were determined immediately after curing of the mosaic facade cladding, that is after a curing period of 14 days at 21 ° C. On the other hand, adhesion values were determined for samples which, after complete curing and bonding of the drawing block to the mosaic, were first subjected to at least 80 consecutive heat-rain cycles, at least 5 consecutive heat-cold cycles and at least 30 consecutive freeze-thaw cycles.

The top of the pull block 17 was the point of engagement of a device, capable of exerting a controlled and measurable tensile force on the pull block 17. The tensile force was now increased systematically and the minimum force, which led to failure of the adhesion, was measured . Adhesion failure consists in one or more layers of the coating coming off the underlying layers. The local adhesion value of the mosaic to the cement fiber board 6 is then the ratio of the measured force value to the size of the area of the underside of the drawing block 17, being approximately 2500 mm ² . The mean adhesion value was then determined by averaging over five such local adhesion values. The results are shown in Table 1. In sample I, the cement fiber boards were wetted prior to priming. This was not the case with sample II.

Table 1: Average Adhesion Values Immediately after curing [N / mm ² ] After running through cycles [N / mm ² ] sample I 0.55 0.47 sample II 0.25 0.47

The average adhesion value of the mosaic to the cement fiber board in samples I, where the cement fiber plates were wetted, was more than twice as high as in samples II, where the cement fiber plates were not wetted. The present invention thus distinguishes from the prior art with an adhesion value, immediately after curing, in excess of 0.50 N / mm ² . Only after a very extreme load, including at least 80 consecutive heat-rain cycles,

BE2016 / 5925 at least 5 consecutive heat-cold cycles and at least 30 consecutive freeze-thaw cycles, the adhesion value drops significantly. In that case, the facade cladding applied according to the present method may no longer be distinguishable from a facade cladding applied according to the prior art. However, it still amounts to at least 0.40 N / mm ² . On the other hand, the adhesion value of a facade cladding applied according to the state of the art, that is, without wetting the cement fiber boards, is less than 0.30 N / mm ² immediately after curing.

It is advantageous that the adhesive value of a facade cladding applied according to the present invention is always at least 0.40 N / mm ² . For example, much higher demands can be made on such facade cladding, which is typically the case on curved or twisted exterior walls of buildings consisting of a large number of floors.
