    [Ventilation item for installation between building elements]
    Field of the Invention
    The present invention relates to natural ventilation and drainage provided from one side of a wall to the other side of the wall.
    Background of the Invention
    The building construction is often based on a prefabrication system, where all pieces are made from precast concrete building elements, such as walls, windows and doors etc. The walls are often made as cavity walls, comprising an inner wall and an outer wall, and between the inner wall and the outer wall isolation is provided.
    The joint between the outer wall building elements are often sealed with for example a sealant compound, which provides an airtight joint between the building elements. The sealed and airtight joint prevents all kind of natural ventilation and drainage of condensed liquid through the joints between the building elements of the building construction.
    When there is no natural ventilation and no drainage of condensed liquid from the inside of a cavity between walls to the outside of an outer wall in a building construction, the building construction is not appropriate be used for residential purposes or other purposes, due to huge moisture damage of the building construction. The building construction or part of the building construction may have to be renovated and/or rebuilt, which results in unintentionally and undesirable high costs and time delay.
    Object of the Invention
    The object of the invention is to provide natural ventilation and drainage from the inside of a cavity between walls to the outside of an outer wall in a building construction.
    Description of the Invention
    The present invention addresses this by providing a ventilation insert for natural ventilation and drainage in building construction, wherein said ventilation insert has a front edge and a rear edge, between said front edge and said rear edge, a first contact edge
    DK 2018 70278 A1 and a second contact edge are provided, and between said first contact edge and said second contact edge a contact plane is defined, between said front edge, said rear edge and said first contact edge and second contact said ventilation insert has a conduit cover provided, said conduit cover having a sealant surface and a conduit surface, where a ventilation conduit is defined by said first contact edge, said second contact edge, said conduit surface, and said contact plane, said ventilation conduit having a rear opening arranged between said first contact edge and said second contact edge on the rear edge, and an front opening arranged on the front edge and where an air flow channel between the rear opening and the front opening through the ventilation conduit.
    A ventilation insert for natural ventilation and drainage of condensed liquid in building construction, wherein said ventilation insert has a front edge extending along a front side of the building construction when the ventilation insert is inserted into the building construction, and a rear edge extending along a rear side of the building construction when the ventilation insert is inserted into the building construction.
    Between said front edge and said rear edge, a first contact edge and a second contact edge are provided, said first contact edge and said second contact edge extending between the front side and the rear side of the building construction, when the ventilation insert is inserted into the building construction, and between said first contact edge and said second contact edge a contact plane is defined.
    Between said front edge, said rear edge and said first contact edge and second contact said ventilation insert has a conduit cover provided, said conduit cover having a sealant surface facing upwards when the ventilation insert is inserted into the building construction, and a conduit surface facing downwards when the ventilation insert is inserted into the building construction.
    The ventilation conduit is defined by said first contact edge, said second contact edge, said conduit surface, and said contact plane. Said ventilation conduit having a rear opening arranged between said first contact edge and said second contact edge on the rear edge and directed towards a rear side of the building construction when the ventilation insert is inserted into the building construction. A front opening is arranged on
    DK 2018 70278 A1 the front edge and directed towards a front side of the building construction. The ventilation insert is inserted into the building construction, and an air flow channel is provided between the rear opening and the front opening through the ventilation conduit.
    In concrete frame building constructions, where the construction comprises concrete building elements, a joint may be provided. A joint is a junction between the building elements, where the building elements are arranged adjacent without applying a static load from one element to another. The joint may be vertical, horizontal or oblique. The ventilation insert is easily applied into the joint without causing any delay or change in the sealant process, when the joints are being sealed.
    The ventilation insert is preferably for use in a cavity wall arranged in the outer wall, providing natural ventilation and drainage between the wall's cavity and the outside of the outer wall. The ventilation insert may also be arranged between a wall and a frame of a window or door.
    To prevent moisture damage to the building construction, a plurality of ventilation inserts for natural ventilation and drainage may be arranged in the joints. The ventilation insert provides an effective drainage and ventilation and thereby reduces the amount of moisture and condensed liquid inside a cavity wall or a building room. Ventilation insert may therefore eliminate or reduce major renovation and repair costs, due to long term moisture and condensed liquid damage.
    In an advantageous embodiment of the invention, the ratio between a cross-sectional area of said rear opening and a cross-sectional area of said front opening is at least 2 : 1.
    The cross-sectional area of rear opening is preferable as large and wide as possible, to provide an easy access so the condensation of the moisture, which is changed into a liquid form, may run out through the ventilation conduit provided between the ventilation insert and the building element. At the same time the cross-sectional area of said front opening must be as small as possible to prevent pests to enter into the cavity wall and to prevent the pests to damage the building construction from the inside of the outer wall.
    DK 2018 70278 A1
    In a further advantageous embodiment of the invention, the sealant surface has an oblique tapering shape extending from the front opening towards the rear opening of the ventilation insert.
    The sealant surface has a tapering shape extending from the front opening towards the rear opening of the ventilation insert, said tapering shape of the sealant surface resulting in a sealant surface of the ventilation conduit being directed, in an oblique manner, towards a front side of the building construction when the ventilation insert is inserted into the building construction. The cross-sectional height of the rear opening may then be higher than the cross-sectional height of the front opening. Preferably, the crosssectional width of the rear opening may be larger than the cross-sectional width of the front opening.
    In a still further advantageous embodiment of the invention, where a cross section of the ventilation conduit, seen parallel to a cross-section of the rear opening, is shaped as at least one part of a concave polygon.
    The shape of the ventilation conduit from the front opening to the rear opening may be a strong and agile, and still relatively resilient construction. Due to the assembling process and build-in properties, the ventilation insert must be strong as a bridge when the joint is sealed with sealant. When sealed, the shape may provide flexible properties working together with the building construction, so the sealed joint may be kept in same condition when the ambient temperature is changing back and forth.
    The cross-section of the ventilation conduit, seen parallel to a cross-section of the rear opening, may be shaped as at least one part of a concave polygon, which may have a triangular shape or another polygonal or semi polygonal shape. The shape may also be a curved concave shape.
    The invention also provides further advantageous embodiment, where the ventilation insert has a limiting edge along the rear edge of said ventilation insert, where the limiting edge extends from the rear edge in an opposite direction of the contact plane, away from the ventilation conduit.
    DK 2018 70278 A1
    When the line of sealant is pulled over the sealant surface of the ventilation insert, the sealant is prevented by the limiting edge to be led behind the ventilation insert and thereby blocking the rear opening or reducing the efficiency of the natural ventilation and draining of the ventilation conduit. The height of the limiting edge may depend on the building construction for which the ventilation insert is to be a part of.
    In a further advantageous embodiment of the invention, where the ventilation insert is made of at least one of the following material: polymers, metal, silicone, paper, cardboard.
    The choice of material of the ventilation insert may also provide features, such as the shape of the ventilation insert, regarding a production of a strong, robust and resilient construction. Due to the assembling process and build-in properties, the ventilation insert may provide a strong and stable ventilation conduit when the joint is sealed with sealant. When sealed, the materials may for example have compatible temperature properties that work together, so the sealed joint is kept in same condition when the ambient temperature is changing back and forth.
    In a still further advantageous embodiment of the invention, where at least one first support foot extends from said first contact edge along said contact plane and away from the ventilation conduit, and at least one second support foot extends from said second contact edge along said contact plane away from the ventilation conduit.
    To support the ventilation insert during the building sealing process, the ventilation insert may be provided with support feet. The support feet may be located on each side of the ventilation conduit providing supporting features, and keeping the ventilation steady and in same predetermined position during the sealing process. The supporting feet may also be provided with a grip or a fitting, which may fit into the building element. The shape of the supporting feet may depend on the building construction for which the ventilation insert is to be a part of.
    DK 2018 70278 A1
    The invention also provides a further advantageous embodiment, where at least one of the first support foot and the second support foot are provided with an adhesive material.
    The adhesive material provided on the bottom side of the first support foot and the second support foot, where the adhesive material facing downwards when the ventilation insert is inserted into the building construction. The adhesive material may be tape or glue or another adhesive compound. The adhesive material provides a firm and steady grip onto the building element when being arranged in a predetermined position in the joint, and keeping the same position when the joint is being sealed.
    The invention further relates to a method of providing natural ventilation and drainage in a joint between at least a first and a second adjacent building element in a building construction, the method comprising:
    - arranging a ventilation insert according to any of claims 1-8 in a joint between a first and a second building element with a first contact edge and a second contact edge of said ventilation insert resting on an upper edge or a lower edge of the first and second building elements,
    - providing a ventilation conduit between a rear side of the first and second building element and a front side of the second building element, the ventilation conduit is defined by a space between the ventilation insert and one of said first and second building elements, providing an air flow channel,
    - arranging the ventilation insert with a rear opening of ventilation insert towards a rear side of the building construction and a front opening of ventilation insert towards a front side of the building construction,
    - joining the first and the second building elements by drawing a line of sealants along the joint, the line of sealant passing a sealant surface of the ventilation insert by continuously drawing the line of sealant along the joint and past the ventilation insert, thereby providing air communication through the ventilation conduit, providing a natural ventilation and drainage through the ventilation conduit after the joint has been sealed with the line of sealants.
    The method provides natural ventilation and drainage using pluralities of ventilation inserts in joints between a pluralities of adjacent building elements in a building con
    DK 2018 70278 A1 struction. The joint may be vertical, horizontal or oblique. By providing pluralities of ventilation inserts in a building construction, unwanted moisture and condensed liquid inside a cavity wall or a building room may be constantly ventilated or drained away from the cavity wall. Ventilation inserts in a building construction may therefore eliminate or reduce major renovation and repair costs, due to long term moisture and condensation liquid damage in a low-cost, easy and efficient way without changes in the sealing process.
    When arranging the ventilation inserts in a joint between a first and a second building element with a first contact edge and a second contact edge of said ventilation insert resting on an upper edge or a lower edge of the first and second building elements, the ventilation insert is easily arranged and stays in the position during the sealing process. The first support foot and the second support foot may be provided with an adhesive material, such as tape or glue.
    When providing a ventilation conduit between a rear side of the first and second building element and a front side of the first and second building element, the ventilation conduit is defined by a space between the ventilation insert and one of said first and second building elements, providing an air flow channel for natural ventilation and drainage. After sealing the joint the air flow channel for natural ventilation and drainage will still be intact.
    When arranging the ventilation insert with a rear opening of ventilation insert towards a rear side of the building construction and a front opening of ventilation insert towards a front side of the building construction, it is preferable that the rear opening is as wide as possible, leaving a wide passage for the condensed liquid running through the ventilation conduit and out into the ambient area outside and away from the building construction.
    When joining the first and the second building elements, a line of sealants is drawn along the joint. The line of sealant passes a sealant surface on the ventilation insert. By continuously drawing the line of sealant along the joint, the line of sealant is passing the ventilation insert, thereby providing air communication through the ventilation
    DK 2018 70278 A1 conduit, and providing natural ventilation and drainage through the ventilation conduit after the joint has been sealed with the line of sealants.
    This method of providing natural ventilation and drainage is low costs, fast implementing, not complicated and very effective.
    A building construction having laterally adjacent first and a second building elements, and where a joint is provided between the first and second building elements, and where at least one ventilation insert is inserted into the joint, where a sealant is provided in the joint, and where a conduit of the ventilation insert extends between a front side of the first and second building elements and a rear side of the first and second building elements.
    The accumulated condensed liquid on the inner side of the building elements flows down the wall. The first building element may be arranged underneath the second building and the first building element may be provided with a sloping top surface, which provides a first building element where the inner side is higher that the outer side. Furthermore the width of the top surface of the first building element, measured from the inner side to the outer side, may be wider than the width at the bottom part of the second building element, measured from the inner side to the outer side. The condensed liquid may then drip down from the inner side of the second building element onto the sloping top surface on the inner side of the first building element. The condensed liquid may be lead out of the ventilation conduit, by natural flow due to the slope, to the outer side of the first building element and away from the building construction. This provides a cavity of the building construction substantially dry during temperature fluctuation.

    Detailed Description of the Invention
    Figure 1 shows a ventilation insert which is used for natural ventilation and drainage in building constructions. The ventilation insert 1 has a front edge 4 and a rear edge 3. The ventilation insert 1 also has a sealant surface 2 and a conduit surface which is not shown in figure 1. A first contact edge 5 and a second contact edge 6 are provided between the front edge 4 and the rear edge 3. The first contact edge 5 is illustrated by the X-line. The second contact edge 6 is illustrated by the Y-line. The X-line and the Y-line are together defining a contact plan XY.
    On the rear edge 3 of the ventilation insert 1, a limiting edge 7 is provided on the sealant surface 2. The limiting edge 7 extends from the rear edge 3 on the side of the sealant surface 2 in an opposite direction of the contact plan. The rear edge 3 is forming the ventilation insert partly as a concave polygon. This causes a cross-sectional area of the rear opening of the ventilation insert 1 to form a shape between the contact plan XY and the rear edge 3 as a triangle.
    Figure 2 shows a ventilation insert 1 from a second angle of view. The first contact edge is illustrated by the X-line and the second contact edge is illustrated by the Yline. Between the Y-line and the X-line, the front edge 4 forms a front opening 10. On the opposite side of the ventilation insert 1, a rear edge 3 is forming a rear opening 9. The front opening 10 and the rear opening 9 are in air communication which is provided by the ventilation conduit. The top rim of the ventilation conduit 11 shows the air passage from the front opening 10 into the rear opening 9.
    The ventilation insert 1 is also provided with supporting feet 8' and 8”. The first supporting foot 8' is provided adjacent to the first contact edge illustrated by the X-line and the supporting foot 8' extending along the contact plane away from the ventilation conduit. The second supporting foot 8'' is provided adjacent to the second contact edge which is illustrated by the Y-line and the second supporting foot 8'' extends along the contact plane away from the ventilation conduit in the opposite direction of the first supporting foot 8'. The ventilation conduit of the ventilation insert 1 is defined by the rear edge 3 crossed with the Y-line to the rear edge 3 crossed with the Xline which forms the rear opening 9. The ventilation conduit is furthermore defined by
    DK 2018 70278 A1 the front edge 4 crossed with the Y-line and the front edge 4 crossed with the X-line which is forming the front opening 10.
    Figure 3 shows a ventilation insert 1 from a third angle of view. The conduit surface 12 of the ventilation insert 1 is the opposite side of the sealant surface 2. The conduit surface 12 is forming the ventilation conduit from the rear opening 9 to the front opening 10 which is shown in figure 2. The first supporting foot 8' and the second supporting foot 8” are provided with an adhesive tape which is arranged on the same side as the conduit surface 12. The material of the ventilation insert 1 may be provided in a material which is mixed with polymers. The ventilation insert 1 is then easily formed in a mould or produced otherwise.
    Figure 4 illustrates the use of a ventilation insert 1 in a building construction 14 with a cavity wall. The building construction 14 comprises an outer wall 20 and an inner wall 19. Between the outer wall 20 and the inner wall 19, isolating material 21 is provided. The outer wall 20 comprises concrete building elements. Between a first building element 15 and a second building element 16, a joint gap is provided. The ventilation insert 1 is arranged in the joint between the first and the second building elements so that the first contact edge and the second contact edge of the ventilation insert 1 is resting on the top edge of the first building elements 15. The ventilation insert 1 is arranged so that the rear opening of the ventilation conduit is turned towards the inner side of the building element 18 and the front opening of the ventilation conduit is turned in the opposite direction towards the outside of the building element 17. The space formed by the ventilation insert 1 and the first building element 15 provides an air communication flow through the ventilation conduit between the inner side of the building element 18 and the outer side of the building elements 17. When joining the first building element 15 and the second building element 16, a coherence line of sealants 22 is drawn in the joint. The line of sealant 22 is passing the ventilation insert 1 by continuously drawing the line of sealant over the sealant surface of the ventilation insert 1. The limiting edge on the ventilation insert 1 contributes the sealants and the ventilation insert 1 to be placed exactly at the intended location and passing the sealant surface of the ventilation insert 1 with the line of sealants 22 thereby providing of stationary air communication through the ventilation conduit. After the joint has been sealed with the line of sealant 22, the ventilation conduit in the ventilation insert 1
    DK 2018 70278 A1 provides a natural ventilation and drainage of condensed liquid in the building construction.
    The condensed liquid accumulating on the inner side 18 of the second building ele5 ment 16, flows down the wall, illustrated by the arrow F. The first building element 15 has a sloping top surface 23, where the width from the inner side 18 to the outer side 17 of the first building element 15, is wider than the width of the bottom part from the inner side 18 to the outer side 17 of the second building element 16. The condensed liquid is then dripping down from the inner side 18 of the second building element 16 10 onto the inner side 18 of the sloping top surface 23, where after the condensed liquid runs out of the ventilation conduit, illustrated by the arrow F', to the outer wall 20 and away from the building construction. This leaves the cavity of the building construction substantially dry during temperature fluctuation.
