Description

Facade construction for thermal insulation and cladding of external building walls and method for producing such

facade construction

The invention relates to a facade construction for thermal insulation and cladding of building exterior walls with a disposed on the building exterior wall thermal barrier coating, a waterproof layer and at least one cladding panel. The invention further relates to a method for producing a facade construction.

In order to reduce energy losses through heat given off via building exterior walls, it is known to apply thermal barrier coatings on the inside or outside of the walls. The thermal barrier coatings are glued to the exterior wall of the building or attached to it with dowels and provided, for example, with a reinforcement and a mineral outer layer. It is also known to protect thermal barrier coatings by gluing or spacing the outer panels apart from mechanical damage and the effects of weathering.

DE 40 07 268 A1 relates to a method for producing a provided with a waterproof coating thermal barrier coating for a building comprising a clam shell outer wall consisting of an inner shell and a spaced therefrom

Outer shell has. The thermal barrier coating is arranged on the outside of the inner shell. However, the outer shell is not glued to the thermal barrier coating, but attached to the inner shell with anchors, which penetrate the thermal barrier coating. The waterproof coating is applied to the insulating layer in the form of an adherent liquid, for example by spraying, painting or trowelling with a layer thickness of 1 to 1.5 mm. The waterproof coating consists of liquid plastic, for example an organic polymer, or of a water-dispersing, semi-liquid latex mixture. The insulating layer is for example a mineral fiber board. As outer shell facade panels made of plastic or natural stone are mentioned.

WO 98/05604 AI relates to inorganic or organic insulating materials, recordable phenolic resin, polystyrene, or Polyurethane rigid foams for insulation against temperature, Schallbzw. Humidity influences. On at least one side of the insulating layer, a waterproof, water vapor permeable functional layer is arranged. For this purpose, a dispersion or solution with polymers based on polyester, preferably Copolyetherestergrundlage, polyurethane base, or polyetheramide base, preferably on the insulating layer

Copolyetheramide base, applied. The application can be done inter alia by spraying, brushing, rolling, dipping, brushing or painting. This document thus relates to a waterproof coating of thermal insulation materials, but does not describe a detailed structure of a building facade.

EP 1 455 027 A1 discloses a thermal insulation element for buildings, wherein the thermal insulation element has an insulation board with lamination arranged on the surface thereof. The thermal insulation element is glued, for example, with a basement wall or attached to this with dowels. The lamination is preferably a glued to the thermal insulation element fiber cement board or plastic plate to protect the thermal insulation element from mechanical damage and save subsequent plaster work.

In the introduction to the description of DE 100 07 775 AI is generally noted on the sticking of aluminum sheets, plastic sheets or wood panels on EPS / XPS thermal insulation panels for special purposes. DE 100 07 775 A1 itself relates to an EPS / XPS plate which is provided on the plate surface to be coated with depressions or an adhesive. On the EPS / XPS plate is a mineral

Outer layer, if necessary with a reinforcement, applied.

The AT 409 986 B relates to a multilayer facing shell for sound and thermal insulation of a building. The front shell has a foam layer formed from interconnected foam rubber, which is glued to the building wall. On the side facing away from the building wall surface of the foam layer is a cover layer, such as a plasterboard or a fiberboard, fixed by means of an adhesive.

The abstract of CN 201128969 Y relates to a polyurethane insulation board having a watertight surface on one side Adhesive layer, another adhesive layer and a waterproof layer may have.

The abovementioned publications thus describe, on the one hand, the coating of a thermal barrier coating with a watertight coating and, on the other hand, the adhering of panels, for example plastic or fiber cement panels, to a thermal barrier coating.

Although the arrangement of a superior facade on a thermally insulated building exterior wall meets the requirements for the protection of thermal insulation, but is also labor-intensive and thus costly. In addition, the thickness of the building facade is often increased to an undesirable extent. The described in the prior art direct bonding of outer panels on the thermal barrier coating, however, takes place without extensive measures to protect the thermal barrier coating from moisture, which in particular at

Outdoor arrangements can also cause frost damage. The disclosed constructions also limit the often desired flexibility in designing the exterior appearance of the facade.

It is thus an object of the present invention to avoid or at least reduce the disadvantages resulting from the prior art and to construct a facade which can be produced in the simplest possible time, in a simple manner and thus cost-effectively. In addition, the facade construction should be durable and long-term damage to the building fabric, for example, by penetrating into the thermal barrier coating moisture due to driving rain or other environmental influences, can be avoided. In particular, the facade design should have the necessary for the achievement of road safety mechanical stability and at the same time allow a visually pleasing as possible external appearance and increased creative freedom.

This object is achieved in that the covering plate via at least one bonding portion is bonded to the waterproof layer and the waterproof layer having disposed on the thermal barrier coating waterproof reinforcement and / or a waterproof coating of the / a arranged on the thermal insulation layer ^■ reinforcement. The thermal barrier coating is glued in a conventional manner with the side of the building exterior wall to be insulated and / or secured with dowels. When Adhesive can be used, for example, a cement-based mineral powder adhesive. Both the thermal barrier coating and the adhesive layer may be designed or arranged to be moisture-wicking, vapor-permeable or vapor-retarding. The reinforcement arranged on the side of the thermal barrier coating facing away from the exterior wall of the building comprises a layer of reinforcing mortar into which a reinforcing mesh is inserted. The reinforcing fabric can either be pressed onto a first part-layer of the reinforcing mortar in order subsequently to be covered with a second sub-layer of reinforcing mortar, or the reinforcing fabric is pressed into a largely finished layer of reinforcing mortar. The purpose of the reinforcing fabric is to prevent the formation of stress cracks, which are due for example to changing temperature influences, within the layer of reinforcing mortar largely. As reinforcement fabric, as known from the prior art, mesh or lattice-like

Structures or fabrics and, for example, knitted fabrics, scrims or fleece can be used. To prepare a reinforcement, for example, an alkali-resistant glass fiber fabric can be embedded in a filler made of a cement-based mineral powder adhesive.

The waterproof layer prevents penetration of

Moisture in the thermal barrier coating and thus damage to this. In the cold season, the humidity could also

Cause frost damage, the elimination of which is associated with corresponding financial expense. If the watertight layer is formed by means of a watertight reinforcement, which is applied to the thermal barrier coating in a manner known per se, then, for example, a further coating for protection against penetrating moisture can be dispensed with. A waterproof reinforcement is achieved for example by means of a sand, light mineral aggregates, white cement and white lime mortar. Likewise, a waterproof, possibly diffusion-open, reinforcing fabric could be embedded in a non-waterproof reinforcing mortar.

However, the reinforcement can not be waterproof. In this case, a waterproof, adhesive coating, preferably a dispersion or solution with polymers, is applied to the reinforcement to form a waterproof layer to obtain. Preferably, although not necessarily, the waterproof layer is formed to be open to diffusion or at least steam-retarding. This allows the delivery of existing in the armor or in the thermal barrier coating moisture.

In order to achieve an even more reliable seal against moisture with the watertight layer, a waterproof reinforcement can additionally be provided with a watertight coating.

It is also essential that the watertight layer is arranged substantially uninterrupted at least in the area of the facade to be protected from moisture and forms a permanently stable connection with the thermal barrier coating. In order to protect the thermal barrier coating and the waterproofing layer from harmful environmental influences or general mechanical damage, as well as for aesthetic facade design purposes, at least one, but generally a plurality of trim panels are secured to the waterproofing layer. The attachment takes place according to the invention by means of an adhesive connection. Such a frictional connection offers over positive connections the advantage that no labor-intensive assembly steps to provide anchors to the building exterior wall are required. In addition, caused by any anchoring or screw connections caused cold spots and the required material costs. The cladding panels can thus be attached to the waterproof layer with little time. It should be noted, however, that even if a positive attachment of the cladding panels on the building exterior wall or the waterproof layer is not required, such additional attachment is not excluded under the invention. The cladding panel may in principle be any panel suitable for outdoor use, such as wood, plastic, metal, ceramic, stone or combinations thereof

has, be. The adhesive used for the attachment of the cladding panels is waterproof and has over the expected life of a building facade the required adhesive force. In particular, polymer-bound adhesive is suitable as an adhesive material. The cladding panels are glued over at least one adhesive portion with the waterproof layer. This adhesive section can be applied over the entire surface Be arranged inside the cladding panel, or even in a sub-area thereof. By gluing over only a portion of the cladding panel of the time required for the required coating of the cladding panel shortened with the adhesive material and also the cost of materials can be reduced.

According to a preferred embodiment of the present invention, the adhesive section has at least one double-sided adhesive strip and / or at least one adhesive layer of polyurethane adhesive or polyurethane foam. The bonding of the cladding panels by means of a double-sided adhesive, in particular adhesive eifens, offers the advantage of immediate adhesion of the cladding panel on the waterproof layer. The number of adhesive strips is not limited in the invention and preferably depends on the weight and the size of the cladding panel used. By providing a suitable number of adhesive strips thus additional fastening means are not required. The double-sided

Adhesive, which are preferably strip form, but are not limited thereto, can already be glued to the production of the cladding plate on one side, so that at the construction site for bonding the cladding panel with the waterproof layer, for example, only a protective strip must be removed from the tape , As an alternative to a double-sided adhesive strip, the adhesive layer can be formed from polyurethane adhesive or polyurethane foam applied to the inside of the lining panel. It is particularly advantageous if the cladding panel is glued to the waterproof layer both with a double-sided adhesive strip and with an adhesive layer of polyurethane adhesive or polyurethane foam. In this case, the adhesive layer is arranged in the area not covered by the adhesive strip, the quantity of applied adhesive material being selected depending on the weight and the area of the cladding panel used. The advantage of this combination of double-sided adhesive strips and at least one adhesive layer is, in particular, that the double-sided adhesive strip results in an immediate bonding to the waterproof layer, which holds the lining plate in the desired position, while the additional adhesive layer gradually achieves its final effect. assumes the adhesive strength. The use of polyurethane foam offers the particular advantage that it expands between the cladding panel and the waterproof layer and thus is achieved with a low material up and a correspondingly large adhesive surface. In addition, polyurethane foam over polyurethane adhesive has the advantage of lower material costs. The distance between the cladding panel and the watertight layer caused by the height of the possibly arranged double-sided adhesive strip is not restricted within the scope of the invention but is preferably a few millimeters.

If the double-sided adhesive strip arranged substantially vertically, the cladding panel is particularly well compared to a horizontal arrangement of the double-sided adhesive strip against a mainly due to gravity slipping in the vertical direction and a detachment of the

Covering panel secured by the waterproof layer due to the now missing connection to the horizontally arranged adhesive strip. The arrangement of the double-sided adhesive strip on the waterproof layer, however, must by no means take place exactly vertically. It is essential, as described above, that the double-sided adhesive strip ensures stable attachment of the trim panel. A substantially vertical arrangement of the adhesive strip also has the advantage that penetrating moisture, for example by

Driving rain, can not accumulate on the long upper edge of a horizontally extending adhesive strip, which in particular during the cold season frost damage and thus damage to the facade construction can be prevented by freezing the accumulated water masses.

It is furthermore particularly advantageous if the circumference of at least one adhesive layer is substantially circular or annular and optionally existing double-sided adhesive strips are spaced from the adhesive layer. Although in principle the adhesive layer can have any shape, these vertically directed depressions, in which moisture or water can collect, should be avoided. The arrangement of the adhesive layer in circular or ring shape allows the flow of moisture penetrating at the edges of this adhesive layer, when the edges of any arranged double-sided adhesive strips do not contact. The application of the adhesive layer in Kreisbzw. Ring shape can also be particularly time-saving, as this is possible without multiple discontinuation of the adhesive container. In addition, the adhesive region advantageously has correspondingly large strains in the horizontal and vertical directions. Deviating from a circular or ring shape, the adhesive layer can of course be circular or ring-like, such as elliptical, applied.

In a further advantageous embodiment of the invention, at least one adhesive layer is arranged pointwise or stripwise, preferably substantially vertically. Both by means of a pointwise as well as stripwise arrangement of the adhesive layer, a preferably substantially uniform distribution of the adhesive layer between the cladding panel and the watertight layer can be achieved in a material-saving manner. Due to a generally caused by the pressing of the cladding plate broadening of the dot-wise or strip applied adhesive layer, the distance between the individual points or strips is selected such that no contiguous, over the width of the cladding plate extending adhesive layers arise at the top of penetrating moisture rainwater could collect. For this reason, it is also preferable to arrange strip-wise adhesive layers substantially vertically so that water that has penetrated between the lining plate and the watertight layer can flow off as unhindered as possible. Of course, the adhesive layer for bonding a cladding panel may have both pointwise and stripwise sections.

In a further embodiment of the present invention, a plurality of cladding panels are spaced apart. The cladding panels may in this case be spaced both vertically and horizontally from each other. Since the cladding panels do not necessarily have to adjoin one another and in particular do not have to have a watertight connection with each other, the façade can in principle be adequately designed for aesthetic requirements. For example, it would be possible to arrange the cladding panels stripwise horizontally or vertically at a distance from the respective adjacent strips. In order to further improve the visual impression of the facade construction, the color of the waterproof layer can with be matched to those of the cladding panels. The penetrating due to environmental influences between adjacent and spaced cladding panels moisture is either in the case of a full-surface bonding of the cladding panel can not penetrate between these and the waterproof layer and thus flow unhindered over the front or the edge of the cladding panel or in the case of non-full-surface bonding over gaps between the cladding panel, the waterproof coating and the adhesive layer can drain.

If at least one cladding panel has at least one photovoltaic element, the facade structure can also be used for energy generation. The type of photovoltaic element is basically not restricted in this case and includes, for example, photovoltaic plates, photovoltaic films and photovoltaic coatings. The photovoltaic elements may have the size of the cladding panel or be formed smaller. The shape of the photovoltaic elements is not limited. In addition, several identical or different photovoltaic elements can be arranged on the cladding panel. The attachment of separate photovoltaic elements on the cladding panel is carried out in a known manner and can be carried out at the construction site or already at the production site of the cladding panel. The photovoltaic element may also be part of the cladding panel itself.

The invention further relates to a method for producing a facade construction, wherein a thermal barrier coating is mounted on a building exterior wall and provided with a reinforcement, wherein the reinforcement is waterproof and / or a waterproof coating is applied to the reinforcement and at least one trim panel over at least one

Adhesive portion is bonded to the waterproof coating or the waterproof coating. The application of the thermal barrier coating on the building exterior wall takes place here in a conventional manner by gluing, optionally using additional fasteners such as dowels. The thermal barrier coating is provided with a reinforcement, which is used for

Protection of the thermal barrier coating from moisture penetration is waterproof or waterproof coated or both waterproof and waterproof coated. To protect the thermal barrier coating from moisture penetration, any waterproof coating is applied to the reinforcement without interruption, at least in the region of the exterior wall of the building to be protected from moisture. The application may be carried out by means known to those skilled in the art, for example by brushing, spraying, rolling or other methods. The watertight formation of a reinforcement or the watertight coating of a reinforcement, which itself may also be waterproof, has the particular advantage that, because of the reinforcement fabric, temperature-related or other environmental cracks in the waterproof layer are avoided. The waterproof reinforcement or the waterproof coating can also, as known from the prior art, be designed to be open to diffusion or vapor-damping. The at least one trim panel is bonded to the waterproof layer at least via an adhesive section. This includes both a full-surface bonding and an arrangement of the adhesive on portions of the inside of the cladding panel. A full-surface bonding in this case has the particular advantage that moisture can not penetrate between the cladding panel and the waterproof layer.

A preferred embodiment of the method is characterized in that at least one adhesive layer of polyurethane adhesive or polyurethane foam and optionally, preferably in the vertical direction in the bonded state, at least one additional double-sided adhesive strip is applied to the cladding panel. The at least one double-sided adhesive strip can be applied to the trim panel both at the factory prior to delivery to the construction site and at the construction site itself by delivering the trim panel and the at least one double-sided adhesive strip separately. By peeling off a protective film from one side of the double-sided adhesive strip, it can be glued to the trim panel, for example. The arrangement of the double-sided adhesive strip in a preferably vertical direction on the watertight layer offers the advantage of improved securing of the lining panel against slipping as compared to a horizontal arrangement. In addition, this arrangement allows in the vertical direction easier drainage of between the cladding panel and waterproof layer einrin- gender moisture. On the provided with the double-sided adhesive strip panel plate also an adhesive layer of polyurethane adhesive or polyurethane foam can be applied to even better bonding. to reach the cladding panel with the waterproof coating. For gluing, the cladding panel is pressed onto the waterproof layer in the desired position, the double-sided adhesive strip providing an instant adhesive bond. The

However, cladding panel could also be bonded to the waterproofing layer without a double-sided adhesive tape and only using the aforementioned adhesive layer.

It is particularly advantageous if at least one adhesive layer is applied to the trim panel in pointwise or strip-like fashion in the substantially vertical direction in the bonded state. The adhesive layer is applied here at the site of the construction site, wherein an optionally applied strip-like adhesive layer, when the cladding plate is glued to the waterproof layer, is oriented substantially in the vertical direction. The adhesive layers are also applied in such a way that they form as possible no marginal areas in which water could collect, allowing unhindered outflow of water. In particular, by the adhesive layer applied dot-wise or in strips, horizontally extending adhesive layers having vaulted edge regions in the vertical direction, in which water could accumulate, are avoided. It when the adhesive layers are arranged substantially uniformly between the cladding panel and the waterproof layer is particularly advantageous.

Particularly advantageously, at least one adhesive layer is applied in a substantially circular or annular manner and at a distance from optionally present double-sided adhesive strips to the trim panel. The circle or ring shape allows a particularly time-saving application, wherein the bonding also takes place over a large area. However, the invention is by no means limited to the precise formation of the adhesive layer in circular or ring shape, but it is essential that the formation of the edge region of the adhesive layer prevents accumulation of water and allows unhindered outflow of the same. Here it is also essential that between the circular or annular adhesive layer and the possibly arranged double-sided adhesive strip a sufficiently large distance is provided so that a through

Pressing the cladding panel on the waterproof layer caused broadening of the adhesive layer does not lead to the contact of the edge region with the double-sided adhesive strip, since water could accumulate in the area between the double-sided adhesive strip and the edge region of the adhesive layer.

The invention will be further elucidated below on the basis of preferred non-limiting exemplary embodiments with reference to the drawing. Show it:

Fig. 1 shows a facade structure according to the invention in a view from above with a building exterior wall 1, a thermal barrier coating 2, a reinforcement 3, a coating applied to the reinforcement 3 waterproof coating 4, two double-sided adhesive strips 5 and a cladding panel 6. The building exterior wall 1 can made of bricks, such as perforated bricks, concrete, in particular reinforced concrete or aerated concrete, sand-lime brick or other materials suitable for coating with thermal insulation elements. The thermal barrier coating 2 may be preferably, but not limited to, be formed from polystyrene foam boards, in particular EPS or XPS boards or mineral fiber boards and attached to the building exterior wall 1 in known manner from the prior art. The thickness of the thermal barrier coating 2 is preferably selected in the range of 12 to 20 cm, but in any case to an extent that the dew point is in the thermal barrier coating 2 and not in the building exterior wall 1. This is due to temperature fluctuations Moisture in the building exterior wall 1 avoided. Any moisture arising in the heat-insulating layer 2 as a result of temperature can be dissipated into the environment via the reinforcement 3, the possible waterproof coating 4, the adhesive section and the cladding panels 6, if these components are advantageously designed to be vapor-permeable or vapor-damping but not vapor-barrier-inhibiting. The thermal barrier coating 2 is on its side facing away from the building exterior wall 1 side with a reinforcement 3, for example, a mineral Armierungsspachtel with a water vapor diffusion resistance number μ = 20, provided, this reinforcement 3, to protect the thermal barrier coating 2 from penetrating moisture, with a waterproof Be - Layer 4 is provided. An embedded in the reinforcing layer 3 reinforcing fabric is not shown for reasons of clarity of the illustrations. The reinforcement 3 is preferably formed with a layer thickness of 5 to 6 cm. The reinforcing fabric is preferably arranged in the outer third or at least in the outer half of the reinforcing layer 3. However, the reinforcement 3 could also be made waterproof, in which case the waterproof coating 4 omitted or, in order to increase the security against penetrating moisture, may be additionally arranged. The thickness of a possibly applied coating 4 is preferably in the range of at most 1 mm. This allows for larger layer thicknesses a material-saving coating and favors the passage of water vapor through the waterproof

Coating. According to the example in FIG. 1, the cladding panel 6 is adhesively bonded to the watertight coating 4 only by means of two double-sided adhesive strips 5, forming an air gap 7, which allows unimpeded outflow of rainwater. Fig.l also shows a arranged on the outside of the cladding panel 6 photovoltaic element 14th

Fig. 2 shows in the direction of the arrows A in Fig. 1 viewed the inside of a cladding panel 6 with two arranged along the vertical sides of double-sided adhesive strips 5, three circular adhesive layers 8 and an annular adhesive layer 9. The adhesive layers 8 and 9 are advantageously substantially uniform arranged distributed on the inside of the cladding panel 6. The shape of the adhesive layers 8 and 9 allows unhindered drainage of penetrating moisture. or rainwater.

Fig. 3 shows the inside of a cladding panel 6 with two vertically arranged double-sided adhesive strips 5 and an annular adhesive layer 9, which was placed at a short distance from the double-sided adhesive strips 5, so that caused by the pressing of the cladding panel 6 to the waterproof coating 4 Broadening leads to a contact with the double-sided adhesive strip 5. Between the cladding panel 6 and the waterproof layer 4 penetrating moisture or rainwater 10 is prevented in this case from flowing out and could in particular in the case of

Freezing damage to the facade construction.

Fig. 5 shows a four cladding panels 6 comprehensive facade section 13, wherein the cladding panels 6 are arranged in the horizontal direction with a distance d _x and in the vertical direction with a distance d ₂ to each other. However, the cladding panels may be arranged without spacing to each other, so that in particular a mutual investment of the cladding panels 6 is possible. Although in principle arbitrarily large values of the distances di and d ₂ in the invention are possible, the distance values are preferably chosen so that the cladding panels 6 as needed the necessary protection against environmental influences or general mechanical damage or to the aesthetic design of the Facade fulfill. If the cladding panels 6 are to be arranged at a distance from one another, the distances d _x and d ₂ preferably have a value of approximately 3 to 4 mm. As can also be seen from FIG. 5, different cladding panels 6 can be provided with differently arranged adhesive layers 8, 9, 11, 12. Although in Figs. 2-5, the cladding panels 6 are shown with two vertically arranged double-sided adhesive strips 5, it would also be possible to arrange only a single or more than two double-sided adhesive strips 5 on the inside of the cladding panels 6.

Further modifications and modifications are possible without to deviate from the scope of the invention. Thus, the adhesive layers 8, 9, 11, 12 may have different shapes to the exemplary embodiments, as long as it is ensured that penetrating moisture 10 can flow away unhindered along its edge. Likewise, it is not absolutely necessary to make the double-sided adhesive strips 5 rectangular according to the representations, for example, these could also have an elongated elliptical shape or be replaced by a plurality of substantially individual adhesive spots or adhesive surfaces arranged in a strip. Although, according to an advantageous embodiment of the invention, the adhesive layers 5, 8, 9, 11, 12 are applied to the inside of the trim panel 6, it is of course also possible to apply these adhesive layers 5, 8, 9, 11, 12 to the respective trim panel 6 to arrange opposite points on the waterproof layer 4.
