Description

The invention relates to a clinker brick slips for cladding walls, in particular facades, with a front side and a rear side opposite the front side, the clinker brick slips having two opposing contact side surfaces, an upper end side and a lower end side, the upper end side and the lower end side opposite each other and each have a mounting groove that extends between the contact side surfaces. The invention further relates to a facade system for cladding walls, in particular facades, with at least one substructure for attachment to a wall, the substructure having at least two horizontal profiles that extend along the width of the wall and at least of the substructure or between the horizontal profiles a clinker brick slips can be added.

Clinker brick slips and facade systems of the type described above are known in principle in different embodiments from practice. Clinker brick slips are also known as brick slips or simply brick slips. Such clinker brick slips are used to clad the exterior facades of buildings. In a sense, they are attached to the building facades as a replacement for full bricks. In this case, substructures made of horizontal and / or vertical profiles are used to which the clinker brick slips are mounted. For this purpose, the aprons usually have assembly grooves into which a receiving section of the substructure or the horizontal profiles can engage. In this way, the clinker brick slips are attached or mounted to the substructure.

In the facade systems known from practice, several long horizontal profiles are usually attached to a building wall on top of one another. The clinker brick slips provided with the assembly grooves are then pushed in from the side between two horizontal profiles, so that an upper assembly groove of the clinker brick slips interacts with a lower receiving section of a horizontal profile and a lower assembly groove of the clinker brick slips interacts with an upper receiving section of a horizontal profile arranged below the first horizontal profile. The clinker brick slips of a row of brick slips to be attached are then pushed in one after the other at the lateral end of these two horizontal profiles until the row is complete.

The clinker brick slips and facade systems known from practice have basically proven their worth. It has been shown, however, that the assembly of the known brick slips is very complex, especially in the case of large or wide building walls, since each clinker brick slips have to be pushed into the substructure or between two horizontal profiles from the side. In the case of wide walls or facades, this is very complex and, in particular, time-consuming. In addition, with these facade systems or clinker brick slips known from practice, the problem is that in the event of damage to a brick slips within a row of clinker brick slips, all intact brick slips have to be pushed out laterally from the substructure in order to replace the damaged brick slips. Then the row of straps must be completed again. This is also time-consuming and disadvantageous, especially in the case of wide facades. - In this respect there is a need for improvement.

In contrast, the invention is based on the technical problem of specifying a clinker brick slips with which the disadvantages described above can be effectively and functionally avoided and which in particular can be easily mounted on a substructure and can be replaced with as little effort as possible in the event of damage. Furthermore, the invention is based on the technical problem of specifying a facade system made up of a substructure and at least one clinker brick slips of this type.

To solve the technical problem, the invention teaches a clinker brick slips for cladding walls, in particular facades, with a front side and a rear side opposite the front side, the clinker brick slips having two opposing contact side surfaces, an upper end side and a lower end side, the upper one The end side and the lower end side are opposite and each have at least one assembly groove which extends between the contact side surfaces, characterized in that the rear groove surface of at least one of the assembly grooves, preferably the assembly groove arranged on the upper end side, has an angle of inclination β of 1 ° to 30 ° , preferably from 5 ° to 25 °, preferably from 10 ° to 20 ° with a vertical apron surface, preferably with the back and / or the front side.

Instead of the term clinker brick slips, the term brick slips is also simply used here and below. In the context of the invention, the front side of the clinker brick slips or brick slips means in particular the side facing the viewer in the mounted state of the brick slips - in which the brick slips are mounted or attached to a substructure. The rear side is opposite this front side and is thus preferably oriented towards the wall or facade in the assembled state of the apron. In the assembled state of the apron, the front side and / or the rear side preferably form vertical apron surfaces.

The term contact side surface of the apron means in particular the lateral sections of the apron arranged between the front and the rear, which extend transversely, preferably perpendicularly, to the front and / or to the back of the apron and, when the apron is installed, to the laterally adjoining one or the next straps in the row of straps are aligned. These contact side surfaces are expediently provided within a row of clinker brick slips for contact with the adjacent clinker brick slips, so that a closed row of brick slips is created. The contact side surfaces are recommended to be planar or planar or essentially planar or essentially planar, so that they can rest directly on the contact side surface, which is likewise planar or planar, of the next apron in the row of aprons. According to an alternative embodiment, the contact side surfaces can also be designed as an interacting tongue and groove system, so that, for example, the contact side surface of a strap is designed with a groove element and the contact side surface of the adjacent strap is designed with a spring element. It is also possible for the aprons of a row of aprons to be arranged at a distance from one another in the assembled state, so that a vertical joint is formed between the aprons, as it were.

In the context of the invention, the upper or lower end side of the clinker brick slips means in particular the sections or surfaces of the brick slips arranged between the front side and the rear side and extending transversely, preferably perpendicular to the front side and / or the rear side, which are closed in the assembled state of the brick slips which are aligned above or below the row of clinker brick slips towards the next following row. The upper and the lower end side extend so in the assembled Condition of the straps horizontally.

In the context of the invention, the expression rear groove surface means in particular the surface of an assembly groove facing the rear side of the clinker brick slips. The angle of inclination β of this rear groove surface results from the angle formed between the rear groove surface and a vertical apron surface, in particular between the rear groove surface and the rear side and / or the front side. Vertical apron surface here means in particular an apron surface that extends vertically or essentially vertically in the assembled state of the apron. Due to the special angle of inclination β that the rear groove surface forms with at least one vertical apron surface and in particular with the rear and / or the front side of the apron, it is possible to mount the apron on a substructure in a particularly simple and reliable manner. The apron can preferably be guided at an angle or angled to the wall from the front to a substructure, a receiving section of a horizontal profile being inserted into the at least one assembly groove, the rear groove surface of which forms the special angle of inclination β with a vertical apron surface. The apron can then be moved from the angled position into a parallel or essentially parallel position to the wall or facade. The apron is then lowered over a certain distance so that the lower mounting groove interacts with another horizontal profile, the apron then being in its mounted position. The inventive design of at least one assembly groove such that its rear groove surface forms an angle of inclination β in the range from 1 ° to 30 °, preferably from 5 ° to 25 °, preferably from 10 ° to 20 °, with a vertical apron surface, enables the individual straps are clicked into the substructure, as it were, without being pushed sideways into the construction would have to. If the brick slips are damaged, it can also be clicked out of the substructure without any problems. The upper and / or the lower mounting groove expediently extends along the entire upper or lower end side, so that the mounting grooves are designed, as it were, as continuous grooves.

According to a preferred embodiment of the invention, at least one of the assembly grooves, preferably the upper assembly groove arranged on the upper end side, has a trapezoidal or substantially trapezoidal cross-section. It is within the scope of the invention that at least one installation groove, preferably the lower installation groove arranged on the lower end side, has a rectangular or substantially rectangular cross-section. Cross-section here means in particular the cross-section transverse or perpendicular to the greatest longitudinal extent of the mounting groove. The cross section of at least one of the assembly grooves, preferably the lower assembly groove arranged on the lower end side of the apron, can also be V-shaped or essentially V-shaped or U-shaped or essentially U-shaped. A particularly preferred embodiment of the invention is characterized in that the apron has an upper assembly groove arranged on the upper end side, the rear groove surface of which has an angle of inclination β of 1 ° to 30 °, preferably 5 ° to 25 °, preferably 10 ° to 20 ° °, with a vertical apron surface, in particular with the back and / or the front side, and that the apron has a lower mounting groove which is arranged on the lower end side and which expediently has a rectangular or substantially rectangular cross-section.

According to a particularly preferred embodiment of the clinker brick slips according to the invention, the groove width bo is at least one Mounting groove, preferably the upper mounting groove, between 15% and 50%, preferably between 20% and 45%, particularly preferably between 25% and 40% of the thickness d of the clinker brick slips. Thickness d of the clinker brick slips means here in particular the thickness of the clinker brick slips, that is to say the greatest extent between the front side and the rear side of the brick slips. It is recommended that the clinker brick slips have a thickness d of 5 mm to 30 mm, preferably 7 mm to 25 mm, preferably 10 mm to 20 mm. In the context of the invention, groove width means in particular the greatest width or extent of the groove between the front side and the rear side of the apron, that is to say transversely or perpendicularly to its longitudinal extent.

A highly recommended embodiment of the invention is characterized in that the groove width bu of at least one installation groove, preferably the lower installation groove, is between 10% and 30%, preferably between 13% and 27%, preferably between 15% and 25% of the thickness d of the clinker brick slips amounts to. The upper assembly groove very particularly preferably has a larger groove width b _O compared to the groove width b _{U of} the lower assembly groove.

A highly recommended embodiment of the invention is characterized in that a transition edge or inclined surface is arranged between the rear side and the lower end side of the apron. The inclined surface preferably extends between the contact side surfaces and particularly preferably over the entire width b of the clinker brick slips. Width b of the clinker brick slips means here in particular the greatest longitudinal extent of the clinker brick slips, that is to say preferably the distance between the contact side surfaces. It is within the scope of the invention that the inclined surface has an angle of inclination γ of 30 ° to 60 °, preferably from 35 ° to 55 °, preferably from 40 ° to 50 °, particularly preferably from 45 ° or about 45 °, forms with a vertical apron surface, in particular with the rear and / or the front. This embodiment of the apron with an inclined surface between the back and the lower end side is based on the knowledge that in the above-described assembly of the apron, in which the apron is initially inclined or angled when being brought up to the substructure, the inclined surface makes it easier Passing the lower end side of the apron on a lower horizontal profile is possible. The lower horizontal profile is intended to interact with the lower assembly groove after the strap has been clicked into place. In comparison to a transition between the rear and the lower end side without an inclined surface, contact with the horizontal profile assigned to the underside of the apron can be avoided in a simple and functionally reliable manner during the assembly of the apron.

It is recommended that the back of the apron has at least one, preferably at least two, particularly preferably at least three, longitudinal grooves. The longitudinal grooves expediently extend between the contact side surfaces and in particular over the entire width b of the clinker brick slips. According to a particularly preferred embodiment variant, the longitudinal grooves run parallel or essentially parallel to one another. The longitudinal grooves are expediently designed as part of a circle in cross section. Cross section here means in particular the cross section transverse or perpendicular to the greatest longitudinal extent of the longitudinal grooves. In principle, the longitudinal grooves can also have a rectangular or essentially rectangular, dovetail or similar cross section. The longitudinal grooves arranged in the back of the brick slips can in particular reduce the weight of the clinker brick slips. According to an alternative embodiment of the invention, the rear side has a groove. The fillet expediently extends between the contact side surfaces and in particular over the entire width b of the apron. The fillet is recommended to have a partially circular cross-section. It is recommended that the fillet extends over at least 50%, preferably over at least 60%, preferably over at least 70% of the height h _{R of} the rear side of the apron. In the context of the invention, height h _{R of} the rear side of the apron means in particular the greatest extent of the rear side of the apron transversely or perpendicular to its longitudinal extent. The fillet expediently represents an alternative to the above-described longitudinal grooves arranged in the rear side and also serves to reduce the weight of the apron.

Height h _{F of} the front side of the apron means here in particular the greatest extent of the front side transversely or perpendicular to its longitudinal extent. It is within the scope of the invention that the rear side protrudes beyond the front side in its height on the upper end side and / or on the lower end side. If, according to a preferred embodiment of the invention, the height of the rear side h _{R of} the strap is greater than the height of the front side h _F , the height of the rear side projects beyond the front side on the upper end side and / or on the lower end side. This expediently results in an upper nose and / or a lower nose on the rear side. If, for example, the back protrudes beyond the front in its height on the upper end side, there is an upper nose on the back. The upper end side is, as it were, divided into two sections by the upper assembly groove, which expediently runs through the entire width b of the apron, and the sub-section facing the rear side then forms the upper nose. This can be done additionally or alternatively on the lower end side with the formation of a lower nose the back will be the case. In principle, it is also possible that the height h _{F of} the front side is greater than the height h _{R of} the rear side, so that an upper nose and / or a lower nose of the front side results or that on a terminating side, the front side is the rear side at its height protrudes and on one end side the rear side of the front side, so that there is a nose on the front side and a nose on the rear side.

It is within the scope of the invention that the clinker brick slips have a rectangular or essentially rectangular basic shape. Then the width b is preferably greater than the height h _R and / or the height h _F. In principle, however, the apron can also have a square or essentially square basic shape. Basic shape here means in particular the shape of the front side and / or the rear side of the strap.

A particularly preferred embodiment of the clinker brick slips according to the invention is characterized in that the brick slips are made from a ceramic mass. The clinker brick slips are preferably produced by extrusion molding of a plasticized ceramic mass. To produce the clinker brick slips, a strand of plasticized ceramic material is expediently extruded or extruded and then brick slips are separated from the strand and then preferably dried and / or burned.

The invention also relates to a facade system for cladding walls, in particular facades, with at least one substructure for attachment to a wall, the substructure having at least two horizontal profiles that extend along the width of the wall and from the substructure or between the horizontal profiles at least one clinker brick slips according to the invention by interaction the at least two assembly grooves can be accommodated with the horizontal profiles.

It is within the scope of the invention that the horizontal profiles are attached directly to the wall or the facade, for example screwed. Alternatively, a plurality of vertical profiles are initially mounted at a distance from one another on the wall or facade and the at least two horizontal profiles of the facade system or the substructure are then attached to the vertical profiles. When the clinker brick slips are mounted on the substructure, there is expediently a gap between the brick slips and the wall or facade. It is recommended that this space be used to ventilate the facade system and / or be filled with an insulating material.

It is within the scope of the facade system according to the invention that the horizontal profiles have at least one spacing section extending transversely, in particular perpendicularly to the wall, at the end of which is preferably at least one assembly section, which is particularly preferably parallel or substantially parallel to the wall and transversely or . extends perpendicular to the spacer section. The spacer section also ensures the spacing between the mounted brick slips and the wall. The assembly section, which is arranged transversely or perpendicularly to the spacer section, is provided for interaction with the assembly grooves of the clinker brick slips.

A preferred embodiment of the facade system according to the invention is characterized in that the assembly section has an upper receiving section and a lower receiving section, the upper receiving section for receiving the lower assembly groove of a clinker brick slips a first row of clinker brick slips and the lower receiving section is provided for receiving the upper assembly groove of a clinker brick slips of a second, in particular a row of clinker brick slips arranged below the first row of clinker brick slips. The spacer section of the horizontal profiles preferably divides the assembly section into at least two parts, and specifically recommended into an upper receiving section and a lower receiving section. If, according to a preferred embodiment of the facade system according to the invention, a large number of horizontal profiles are mounted on the wall or facade, the clinker brick slips according to the invention can each be received or clicked between two horizontal profiles, namely through the interaction of the assembly grooves of the clinker brick slips with the horizontal profiles. Incidentally, a horizontal joint is preferably formed between the rows of clinker brick slips due to the distance between the rows. Within the respective row of clinker brick slips, the slips can preferably rest against one another with their contact side surfaces or be arranged at a distance from one another and then, as it were, form a vertical joint.

A particularly preferred embodiment of the facade system according to the invention is characterized in that the upper receiving section of the mounting section has a lower receiving height xo than the lower receiving section. This expediently results in an asymmetrical T-shape in the cross section of the horizontal profile or of the assembly section and of the spacer section. The upper receiving section of the mounting section, which is assigned to the lower mounting groove of a clinker brick slips, is, as it were, _{shorter in terms of its receiving height x O} than the lower receiving section in terms of its receiving height x _U , which is assigned to the upper mounting groove of a clinker brick slip. Here, the receiving height means the extension of the receiving section transversely or perpendicularly to its longitudinal extension. This configuration of the assembly section with an upper, shorter receiving section compared to the lower receiving section enables a particularly simple and functionally reliable installation of the clinker brick slips according to the invention on the horizontal profiles and, in particular, a functionally reliable click-in of the slips.

The invention is based on the knowledge that the clinker brick slips according to the invention can be installed on a substructure in a functionally reliable manner and with little effort. Due to the design according to the invention, at least one assembly groove, preferably the upper assembly groove arranged on the upper end side, with a rear groove surface that has an angle of inclination β of 1 ° to 30 °, preferably 5 ° to 25 °, preferably 10 ° to 20 °, Formed with a vertical apron surface, preferably with the back and / or the front, the aprons can be individually mounted on a substructure or clicked into the substructure so that the aprons do not have to be pushed into the substructure one after the other from the side. This enables, in particular, a simple replacement of damaged brick slips and a less complex assembly of the slips, particularly in the case of large wall or facade surfaces. The apron is led diagonally or at an angle from the front with the upper mounting groove to the lower receiving section of a horizontal profile. In this case, the apron expediently assumes an angle to the wall or to the lower receiving section which essentially corresponds to the angle of inclination β. The rear groove surface of the mounting groove is then expediently aligned vertically for a short time. The lower receiving section is then introduced into the upper assembly groove and the apron is then brought or clicked into a position parallel or essentially parallel to the wall or facade. In the next step, the apron is lowered so that the lower mounting groove with an upper one Receiving section of a further horizontal profile can be brought into interaction. The transition edge or inclined surface provided between the rear side and the lower end side according to the preferred embodiment variant additionally facilitates this assembly process or click process. Overall, the clinker brick slips according to the invention are characterized by a surprisingly great simplification of the assembly process while at the same time the design and manufacture are not very complex. The clinker brick slips according to the invention can be designed variably on the front side and in this respect is characterized by great flexibility in the design options. The advantages of the brick slips according to the invention come into play in particular when used or installed in a facade system according to the invention comprising a substructure and the clinker brick slips.
