Description

In a first aspect, the invention relates to a ventilation duct module according to the preamble of claim 1. In a second aspect, the invention relates to a ventilation system according to claim 18. In a third aspect, the invention relates to a building wall according to claim 19.

Ventilation systems for ventilating buildings are known. Such ventilation systems can remove and / or supply air. In the case of air routing, a connection between a living room on the inside of a building wall and an outside area on the outside of a building wall must be guaranteed. For this purpose, a wall duct is implemented through the building wall with a hole or a similar cutout. A duct, in particular a duct, and / or a ventilation device is integrated within the wall duct. For various reasons, closures (e.g. weather protection hoods or designer interior closures) are installed on the inside and outside of the wall. The closures for the outside area are often visible on the facade of the building. This visibility is often not desired.

For this reason, air ducts are used that guide the air in such a way that a closure is not arranged on the facade, but in the side reveal of a wall cutout. Such reveal channels protect the visual perception of the facade. The reveal channels are integrated in the wall structure. Often they are integrated into the thermal insulation of the wall there.

In the case of wall structures with an outer wall layer, in particular clinker brick, with or without an air layer, the window frames are often built in abutment with the clinker brick. If a soffit channel is to be installed here, it must be integrated within the outer wall layer, in particular within the clinker brick.

The outer wall layer, in particular the clinker bricks, have to be tapered in the area of the soffit canal. Often an installation is not even possible due to the geometry of the reveal channel.

Such a taper weakens the wall outer layer, in particular the clinker wall, especially structurally. Weather conditions, such as wind loads and showers, can cause damage to the outer wall layer, in particular to the clinker brick wall. A tapering of the outer wall layer, especially the clinker bricks, should therefore be avoided.

It is therefore desirable to provide a ventilation duct module and a ventilation system which meet both visual / aesthetic requirements and also reduce structural weakening of an outer wall layer, in particular a clinker brick wall, of a building.

This is where the invention comes in, the object of which is to provide an improved ventilation duct module and ventilation system which at least partially eliminates the problems prevailing in the prior art. In particular, the aim is to enable air to be conducted through the building wall, which meets both optical / aesthetic requirements and also reduces structural weakening of an outer wall layer, in particular a clinker brick wall, of a building.

The object is achieved by the invention with a ventilation duct module of claim 1. The invention is based on a ventilation duct module for a soffit duct, for installation in a building wall with a soffit, having a flow duct which connects a soffit connection and a duct connection to one another in an air-conducting direction,

• - der Laibungsanschluss auf einer Laibungsseite, die der Laibung zugewandt ist, innerhalb eines Modulaußenbereichs angeordnet ist, der an eine Modulaußenseite angrenzt, die einer Außenseite der Gebäudewand zugewandt ist, wobei
• - das Lüftungskanalmodul zwischen dem Laibungsanschluss und dem Kanalanschluss wenigstens einen Bereich aufweist, in der die Luftführungsrichtung normal zur Gebäudewand versetzt wird.

According to the invention it is provided in the ventilation duct module that

• the soffit connection is arranged on a soffit side which faces the soffit within an outer module area which adjoins a module outer side which faces an outer side of the building wall, wherein
• - The ventilation duct module between the soffit connection and the duct connection has at least one area in which the air flow direction is offset normal to the building wall.

Since the reveal connection is arranged on the reveal side within the module outer area, and the air flow direction in the ventilation duct module is offset normal to the building wall, a small module depth of the ventilation duct module is achieved. A small module depth advantageously enables the reveal channel to be integrated into the building wall, which causes only a relatively slight weakening of the outer wall layer, in particular the clinker brick wall. In particular, the outer wall layer is a clinker brick wall.

An offset of the air flow direction normal to the building wall means that the design and arrangement of the flow channel, the air flow guided through the ventilation channel module is offset between two, in particular parallel to the building wall, planes, namely by one Level in which the sewer connection is located to a level in which the reveal connection is located. The air flow direction does not have to be perpendicular to the building wall. In order to offset the air flow direction normal to the building wall, the flow channel is arranged parallel to the reveal side or at a channel angle to the reveal side, which is preferably less than or equal to 45 °, particularly preferably less than or equal to 40 °. The module depth extends perpendicular to the reveal side between the reveal side and an opposite module back.

The smaller the module depth, the greater the advantageous effect of the lower structural weakening of the wall outer layer, in particular the clinker wall. In particular, the outer wall layer is a clinker brick wall.

The ventilation guidance direction describes the flow of the air flowing through the ventilation duct module and lies in the middle of the duct cross-section.

The clinker format, namely the clinker length, the clinker width, and the clinker height is based in particular on the normal format (NF), in which the clinker length is 240 mm, the clinker width 115 mm and the clinker height 71 mm. The thickness of the mortar layer and thus the distance between two clinker bricks is in particular 10 mm. Nevertheless, other clinker formats and / or mortar layers are within the scope of the invention DIN 1053 and or DIN 105 and / or EN 771 possible. A clinker height includes, in particular, a mortar layer.

Advantageous further developments of the invention can be found in the subclaims and indicate in detail advantageous possibilities for realizing the concept explained above within the scope of the task and with regard to further advantages.

• - der Kanalanschluss innerhalb eines Modulinnenbereichs angeordnet ist, der an eine Modulinnenseite angrenzt, die der Modulaußenseite gegenüberliegt, wobei
• - der Kanalanschluss auf einer der Laibungsseite gegenüberliegenden Modulrückseite oder auf der Modulinnenseite angeordnet ist.

In particular, it is provided that

• - The channel connection is arranged within a module inner region which is adjacent to a module inner side which is opposite the module outer side, wherein
• - The duct connection is arranged on a module rear side opposite the reveal side or on the inside of the module.

It is advantageously provided that the ventilation duct module has a module depth that is less than or equal to 120 mm, particularly preferably less than or equal to 110 mm, the module depth extending perpendicular to the reveal side between the reveal side and an opposite module rear side.

Such a further development takes into account the fact that the closure of a clinker wall in front of the reveal is usually formed from solid clinker bricks and clinker bricks halved in their clinker length, alternating in layers. A width of 120 mm is usually half a clinker length, that is, half the length of a clinker brick. In a further development, in which the module depth is half a clinker length or less, only the full clinker bricks have to be tapered and / or notched, and the half clinker bricks can be completely halved along their longitudinal axis to half a clinker width, which advantageously reduces the workload.

The ventilation duct module in particular has a module depth which is designed to be relatively small, in particular half a clinker width, for example less than or equal to 110 mm. The ventilation duct module has in particular a module width which is composed of a duct connection width, which describes the width of the duct connection, and a module core width. The duct connection width is in particular less than or equal to 70 mm and can advantageously be adapted to the width of the soffit duct. The module core width can in particular be adapted to the offset to be bridged in the ventilation guidance direction and can in particular be 106 mm.

It is advantageously provided that an outer area width of the module outer area is half, preferably one third, of a module width, the module width extending parallel to the reveal side between the module outer side and the module inner side. The smaller the outer area width, the closer the reveal connection is arranged to the outside of the module, whereby a further weakening of the outer wall layer is advantageously avoided.

In particular, it is provided that an inner area width of the module inner area is half, preferably one third, of a module width.

It is advantageously provided that the flow channel runs at a channel angle to the reveal side that is less than or equal to 40 °. The channel angle is preferably less than or equal to 20 °, and the channel angle is particularly preferably less than or equal to 10 °. The smaller the duct angle, the smaller the module depth can advantageously be - with a comparable offset of the air flow direction.

It is advantageously provided that the flow channel has a vertically elongated channel cross-section ( AKQ ), in particular a height-to-width ratio of at least 8 to 1. Due to a slight lateral expression of such a vertically elongated channel cross-section, this is particularly suitable for integration in a reveal surface, which is likewise vertically elongated. Due to the correspondingly greater height, despite the small width of the cross-section, a flow cross-section is achieved which is necessary for a required exchange of air.

It is advantageously provided that the reveal connection has a connection extension extending normal to the reveal side and / or normal to the reveal surface. In particular, the connection extension has a connection length that is less than or equal to 120 mm. In particular, the soffit connection and / or the connection extension is designed to accommodate a panel or similar closing element. In particular, the soffit connection and / or the connection extension has a panel or a similar closing element. A connection extension in particular solves the problem that in the state of the art the closures of soffit channels are often not suitable for clinker walls because, for example, a window frame and a closure of a soffit duct often do not have a common installation space in the clinker brick.

It is advantageously provided that the connection extension has an outer side wall facing the outside of the building wall with an outer wall thickness and an opposite inner side wall with an inner wall thickness, the inner wall thickness being greater than the outer wall thickness. Because the inner wall thickness is greater, for example 8 to 25 mm, a connection to a window frame and / or a roller shutter rail can be improved, in particular because an otherwise existing gap is filled by the wall thickness. It is advantageously provided that the inner side wall of the connection extension and / or the soffit connection is arranged to rest against a window arranged in the soffit or against a roller shutter rail arranged in the soffit, the contact being made directly or via a sealant joint.

In particular, it is provided that the ventilation duct module and / or the connection extension is formed from at least one of the following materials: plastic, sheet metal, wood fibers. In particular, the ventilation duct module or the module body or the connection extension is formed from a material that corresponds to the fire class of the insulation, i. H. of the material used in the insulation layer. In particular, the ventilation duct module or the module body or the connection extension is made from an expanded or extruded plastic.

At least one strut is advantageously provided, which is arranged within the flow channel and / or the connection extension. The mechanical stability of the ventilation duct module and / or connection extension can be improved by means of a strut that is designed and / or arranged to be as aerodynamically favorable as possible.

In particular, it is provided that the ventilation duct module is symmetrical to a mirror plane lying horizontally in the center of the ventilation duct module ( SPE ) is trained. Such a symmetrical design can advantageously enable assembly on both sides, ie left and right or above and below in a reveal, without having to vary the design of the ventilation duct module.

In particular, it is provided that the ventilation duct module, in particular a module body of the ventilation duct module, has a cuboid shape. Due to a cuboid shape and the associated right-angled design of the ventilation duct module, it can advantageously be accommodated in a likewise right-angled recess in the outer wall layer. In particular, clinker bricks only have to be processed with straight cuts at right angles to the clinker bricks.

In an advantageous development it is provided that the module body has a bevel, which is arranged between the module outer side and a module rear side opposite the reveal side. In particular, the bevel runs parallel to the air flow direction and / or to the flow channel.

The volume of the module body can advantageously be reduced by a bevel, as a result of which a recess in the outer wall layer can be smaller, whereby the outer wall layer, in particular the clinker wall, is advantageously less structurally weakened.

In particular, it is provided that the ventilation duct module has a screen, in particular a deflection screen with at least one deflection lamella.

In particular, it is provided that the ventilation duct module has a duct connection section with at least one insulation holder receptacle, the at least one insulation holder receptacle being designed to receive an insulation plug. The insulation holder receptacle has, in particular, a cylindrical shape.

In particular, it is provided that the ventilation duct module has a module height which is a multiple of a clinker height and / or a sum of a clinker height and a mortar layer. In particular, the module height is a multiple of 71 mm or 81 mm. In particular, the module height is between 426 mm or 486 mm. With a module height that is a multiple of the clinker height and / or the sum of the clinker height and mortar layer, installation in a clinker wall can advantageously be made possible without having to adjust the height of individual clinker bricks.

In particular, it is provided that the ventilation duct module or the module body is designed and arranged in such a way that an outer wall zone arranged within the outer wall layer parallel to the outside is not exceeded in the direction of the outside of the building, the outer wall zone being spaced at least half a clinker width from the outside inwards .

The building wall 210 has an outer wall layer 220 on, which in the present case is a clinker brick wall 222 is trained. The outer wall layer 220 can in further developments also within the framework of a standard thermal insulation composite system or similar building wall in another, from a clinker brick wall 222 be formed different shape. The outer wall layer 220 closes with an outside 310 of the building 300 away. On the - the outside 310 opposite - side of the wall outer layer 220 an insulation layer closes 230 in the particular insulation material 144 is arranged. In optional further developments, between the wall outer layer 220 and the insulation layer 230 a layer of air 226 be arranged. The layer of air 226 can be an air layer width 228 of up to 40 mm. To the insulation layer 230 closes again in the direction of an inside 320 of the building 300 an inner wall layer 240 at.

A ventilation device 200 and a duct connected to it 142 are in a wall duct 312 arranged, which extends through the inner wall layer 240 and partly through the insulation layer 230 extends. To the duct 142 a soffit duct closes with air 140 which is in the insulation layer 230 parallel to this on the outer wall layer 220 along in the direction of a reveal 212 up to a ventilation duct module 100 extends. The ventilation duct module 100 is within a soffit edge zone LRZ arranged. The ventilation duct module 100 has one in the area of the insulation layer 230 lying sewer connection 120 , and one in the area of the outer wall layer 220 lying reveal connection 110 on. Through the ventilation duct module 100 can thus a ventilation guidance direction LFR from the insulation layer 230 in the outer wall layer 120 be moved. Via the sewer connection 120 is the reveal channel 140 with a module body 130 of the ventilation duct module 100 air-connected. The reveal connection 110 of the ventilation duct module 100 is on one reveal side 137 of the ventilation duct module 100 arranged in the direction of a reveal surface 214 the reveal 212 is directed. Due to the arrangement of the reveal connection 110 in the wall outer layer 220 can be an air flow according to the ventilation direction LFR in one of the reveal 212 enclosed soffit interior 216 or be led out of this. The module body 130 extends in a direction perpendicular to the building wall 210 from the inside to the outside to an outer wall zone WAG, whereby between the boundary of the outer wall zone WAG and the outside 310 the outer wall layer 220 is not impaired, in particular does not have to be left out.

The connection extension 112 closes on the reveal side 137 to the reveal connection 110 at. Via the connection extension 112 can the reveal connection 110 be extended so that it continues towards the reveal surface 214 and / or in the reveal edge zone LRZ and / or in the reveal interior 216 extends into it. The connection extension 112 has a connection length 118 on. The connection extension 112 has an outer side wall 114 with an outer wall thickness WSA and an inner side wall 116 with an inner wall thickness WSI on. The present is the inner wall thickness WSI bigger than the outer one Wall thickness WSA . The ventilation duct module 100 has a flow channel 128 in the module body 130 Is arranged obliquely, namely in a channel angle WK to the reveal side 137 to move the ventilation direction LFR to move from an insulation layer to an outer wall layer. The flow channel 128 has a channel cross-section AKQ on. Optionally, the module body can have a bevel - shown here in dashed lines 132 exhibit. The bevel 132 can be parallel to the flow channel 128 and / or to the air flow direction LFR get lost. In the case of a non-straight course of the flow channel, the channel angle is formed in particular from the mean value of the channel angles of all sections of the flow channel.

In 3 is the ventilation duct module 100 ' when installed in a building wall 210 shown in a sectional view. Via the sewer connection 120 is the ventilation duct module 100 ' to a soffit canal 140 connected. Just before reaching the reveal 212 , in a soffit edge zone LRZ , becomes the ventilation direction LFR from the insulation layer 230 in the outer wall layer 220 offset, and is via the reveal connection 110 and the connection extension 112 to the reveal surface 214 guided. In the present case, the ventilation duct module 100 ' a module depth 104 of approximately half a clinker brick length, and the connection extension 112 a connection length 118 also of approximately half a clinker length. The connection extension 112 is in the present case directly abutting with a window 332 arranged.

4th shows a perspective view of a ventilation duct module 100 " . The module body 130 of the ventilation duct module 100 " has a cuboid shape 138 and in particular has an approximately right-angled outer shape. To the ventilation duct module 100 " , especially on the module body 130 , is at the reveal connection 110 a connection extension 112 connected, the present three over the channel cross-section AKQ vertically spaced struts 160 having. In further developments it is possible, as an alternative or in addition, that the module body 130 Has struts. The ventilation duct module 100 " has a module height 102 on. The ventilation duct module can be made of plastic 180 , Sheet 182 or wood fibers 184 be formed, a combination of these or other materials is also possible. The ventilation duct module 100 " is symmetrical with respect to a mirror plane SPE formed, the mirror plane SPE horizontally at half the module height 102 is arranged.

The ventilation duct module 100 " has a module depth 104 which is advantageously made relatively small, in particular half a clinker width, for example 110 mm. The ventilation duct module 100 " has a module width 106 on. In particular, the module width is set 106 from an interior width 156 one on the inside of the module 135 adjacent module interior 152 which in particular is equal to the width of the duct connection 120 and a module core width 107 together. The interior width 156 is in particular less than or equal to 70 mm and can advantageously match the width of the soffit channel and / or the channel connection 120 be adjusted. The module core width 107 can in particular be adapted to the offset to be bridged in the ventilation guidance direction and can in particular be 126 mm. Within the module core width 107 is one on the outside of the module 134 adjoining external module area 150 with an outside area width 154 arranged. The reveal connection 110 is within the module outer area 150 on the reveal side 137 of the ventilation duct module 100 " arranged.

In 5 is a further development of a ventilation duct module 100 ''' shown with a stabilizing plate 170 . The present is the stabilizing plate 170 designed as an angle plate and above the ventilation duct module 100 '''' arranged adjacent to this in such a way that the horizontal part of the stabilizing plate 170 in a mortar layer 224 as a brick wall 222 trained outer wall layer 220 extends. Through the stabilizing plate 170 Forces from the outer wall layer can advantageously be absorbed and / or distributed and / or a mechanical strengthening of the ventilation duct module 100 ''' can be achieved. The stabilizing plate is advantageous 170 from the reveal surface 214 inwards into the outer wall layer 220 offset and / or by a diaphragm 338 covered so that it is not visible from the outside.

In 6th is a further development of a ventilation duct module 100 '''' shown in the installed state, with a module body 130 ' that has a bevel 132 having. It becomes clear that in such a development the outer wall layer 220 , especially clinker bricks of a clinker wall 222 also only need to be beveled, whereby - in particular in contrast to a right-angled notching of the clinker brick wall - less material has to be removed from the wall's outer layer. In this way, the wall outer layer is advantageously even less structurally weakened.

In 7A is a further development of an aperture 338 in the form of a deflector 340 shown. The deflector 340 has a number of deflection blades 342 on, which are formed from a soffit connection 110 and / or a connection extension 112 to deflect escaping airflow, in particular to direct it away from the building. In particular, the exiting air flow can be deflected away from a window built into the reveal. Such a deflection advantageously prevents a region of the building wall and / or the reveal and / or a component built into the reveal, such as a window, which is adjacent to the panel 332 or door, is heated and / or humidified by the exiting air stream. Thus, long-term visual impairments and / or damage, in particular due to moisture, are advantageously avoided by means of a deflecting screen. The deflector 340 is designed to be connected to a soffit 110 and / or to a connection extension 112 to be connected. 7B shows a cross-sectional view of the deflector 340 in a cutting plane SE . The present is a number of five deflecting lamellas 342 visible, which are arranged side by side and are formed by their curved cross-section, the air flow direction LFR one from a ventilation duct module 100 to change exiting air flow, in particular to direct the air flow away from the building.

The sewer connection section 122 especially after the ventilation duct module has been installed 100 '''' within an insulating layer, not shown 230 is arranged, in the present case has four insulation holder mountings 127 on, two of which are visible. An insulation holder mount 127 is to accommodate an insulation holder 124 educated. The essentially shaft-shaped insulation holder 124 has a round, disk-shaped insulation holder head 124.1 on. The insulation holder mount 127 is designed in such a way that it is in the assembled state of the insulation holder 124 both the insulation holder head 124.1 , as well as an insulating plug 126 like this in 8A in the insulation holder mount below 127 , as in 8C is shown. An insulating plug can be made of styrofoam or similar insulating material, in particular from the same material as an insulating material 144 in the insulation layer 230 or from a material that is also used in the duct connection section 122 is used. In 8B is the ventilation duct module 100 '''' shown in a sectional view in the pre-assembly state.
