Description

An outer frame element, a set of parts, a wall construction, and a method for assembling a fire-shielding wall construction

Field of the invention

The present invention relates in a first aspect to a fire-shielding Ushaped outer frame element adapted for supporting a side of at least one glazed partition in a wall construction. The invention also relates in a second aspect to a set of parts comprising a fire-shielding U-shaped outer frame element, in a third aspect to a method for mounting a glazed partition, and in a fourth aspect to a wall construction.

Background of the invention

The need for a good and reliable fire protection system in commercial buildings and office complexes has gained significant importance in recent years. Fire and fire-related hazards can cause heavy loss to life, property and critical data.

Modern technology permits the use of glass in walls without compromising fire safety standards, since incorporation of fire-rated glass is possible. Fire-rated glass is suitable for use for example in stairwells, computer rooms, evacuation routes in large office buildings, hospitals, shopping centres and other fire sensitive areas. Such glass walls help to prevent flames, heat, smoke, and hazardous gases from spreading.

When wall elements, such as glass wall elements, are assembled to form a wall construction, including partition walls, folding partitions, panel walls etc., an outer frame is used to support the wall elements, the frame being connected to the adjacent floor, ceiling, and/or walls. The outer frame may consist of a variety of materials, most common are aluminum, stainless steel or wood, depending on the desired properties of the frame.

The applicant’s WO 2016/023562 A1 discloses a fire-shielding Ushaped outer frame element adapted for supporting a side of at least one wall element, such as a glazed partition, in a wall construction, said outer frame element being elongate and comprising and end wall and a first side

DK 2018 70142 A1 wall and a second side wall extending at an angle to the end wall, interior surfaces of the side walls being adapted for extending along exterior surfaces of the wall element. The outer frame element comprises a plurality of perforations and a first elongate strip of a material having thermal shielding properties and being arranged on a surface of the first and/or second side flange of the outer frame element so as to shield the wall element from heat from a fire.

On this background, it is an object of the invention to provide an improved fire-shielding outer frame element, which is able to be built into more kinds of building structures than the frame element of the prior art and may further improve the fire-shielding properties of the wall construction in which the frame element is used to support the wall element.

Summary of the invention

In a first aspect of the invention, this and other objects are achieved by a fire-shielding outer frame element adapted for supporting an edge of a fireshielding glazed partition, the frame element comprising a U-profile which is elongate in a longitudinal direction and comprises a first side wall and a second side wall extending in a height direction perpendicular to the longitudinal direction from an opening of the U-profile to an end wall extending in a width direction perpendicular to the longitudinal and height directions, said end wall connecting the first side wall and the second side wall, whereby the end wall, the first side wall, and the second side wall define an open cavity for accommodating the edge of the fire-shielding glazed partition, an interior surface of the first side wall being adapted for extending along a first major surface of the glazed partition and an interior surface of the second side wall being adapted for extending along a second major surface opposite the first major surface of the glazed partition in a mounted condition, wherein each interior surface is provided with a strip of compressible fire-resistant material extending in the longitudinal direction, said strips of compressible fire-resistant material being adapted for engaging the glazed partition so that the glazed partition is retained between the strips

DK 2018 70142 A1 of compressible fire-resistant material when mounted.

It should be noted, that the above-defined longitudinal, height, and width directions which have been used to describe the frame element, does not necessarily relate to a final orientation of the U-profile when mounted. As an example, the frame element may be used to support the side edge of a glazed partition, in which case the height direction of the frame element will correspond to a direction in the horizontal plane. Furthermore, the directional terms “upwards” and “downwards” when used herein will refer to directions in the height direction, “upwards” being away from the glazed partition and “downwards” being towards the glazed partition, while “outwards” and “inwards” will refer to directions in the width direction “inwards” being towards the cavity of the U-profile and “outwards” being away from it.

The term glazed partition as used herein, refers to a glazed panel, single or multi-layered, with two major surfaces and at least one straight outer edge. Although the frame element of the invention can be used to support a glazed partition an arbitrary shape with a straight edge, it will predominantly be used for rectangular glazed partitions, i.e. a glazed partition with a top, bottom, and two side edges.

When retained between the two strips of fire-resistant material, the glazed partition will, due to the compressibility and elasticity of the fireresistant material, be able move in the height and longitudinal directions in relation to the frame element. The wall construction, i.e. the mounted glazed partition supported by the frame element, will therefore allow for some degree of horizontal and vertical movement of glazed partition and the frame element with respect to each other. This may allow not just the frame element but also the glazed partition to undergo thermal expansion in the case of fire. This may mitigate the stress put on these elements during such extreme conditions, and help prolong the time the wall construction can withstand the heat exposure.

Furthermore, by allowing the frame element and the glazed partition to move in relation to each other, the wall construction may experience less

DK 2018 70142 A1 stress when the structure the wall construction is built into experiences natural movement, e.g. due to changes in the underground or foundation. This may be particularly relevant for buildings where the settlement is greater than normal. Another instance where it is advantageous to allow movement of the glazed partition in relation to other building components is when the frame element is used to support a glazed partition in steel structures such as ships or similar, where the structure surrounding the glazed partition is further expected to show some degree of vibrational movement.

The outer frame element may be made from a material chosen from the group consisting of aluminum, steel, alloys, composites, carbon fiber and/or glass fiber, or made from a combination of such materials, but any non-flammable material having a high strength and a high melting point may in principle be used. The use of materials having a low thermal conductivity may also be advantageous.

In an embodiment of the invention, an interior and/or exterior surface of the end wall is provided with a strip of intumescent fire-resistant material. When used herein, the term intumescent refers to a material which will expand when subjected to the heat levels associated with fire.

By providing a strip having intumescent properties on the interior and/or exterior surface of the end wall, any gap between the outer frame element and an adjacent floor, wall or ceiling and/or between the frame element and the glazed partition will be sealed during a fire. This will shield the frame element and help in preventing heat from the fire from moving from one side of the wall construction to the other side.

In an embodiment of the invention, the strips of compressible fireresistant material are arranged with a spacing between them and the end wall. By arranging the strips of compressible fire-resistant material extending in the longitudinal direction at a distance from the end wall, the edge of the glazed partition can be separated further from the end wall when the glazed partition is engaged by the strips of compressible fire-resistant material and thereby supported by the frame element. This provides the glazed partition additional room for movement in the height direction in relation to the frame

DK 2018 70142 A1 element.

In an embodiment, the width of the strip of compressible fire-resistant material is preferably at least one quarter of the height of the first and second side walls, more preferably at least one third of the height of the first and second side walls. This provides the strip of compressible fire-resistant material with sufficient contact surface with the glazed partition, while at the same time providing space between the edge of the glazed partition and the end wall to allow the glazed partition and the frame element to move more freely.

In a presently preferred embodiment, the U-shaped outer frame element further comprises a first mounting flange connected to the first side wall, said first mounting flange extending away from the second side wall in the width direction, and a second mounting flange connected to the second side wall, said second mounting flange extending away from the first side wall in the width direction.

By providing the frame element with mounting flanges extending outwards in the width direction, it becomes possible to mount the frame element between two parallel wall elements, e.g. of a concrete or gypsum wall, with a gap between them. This is achieved by arranging the frame element between the two wall elements and attaching each of the mounting flanges to a respective one of the wall elements, whereby the frame element is suspended between the two wall elements and the mounting flanges will span the gap between the wall elements.

The gap formed by the two parallel wall elements of common twolayered wall structures are usually wider than the U-profile. When the frame element is arranged in the middle of the gap there will be a spacing between the U-profile and each of the wall elements. A further advantage of mounting the glazed partition with a frame element with mounting flanges extending outwards in the width direction between the U-profile and the proximate wall element, is that the framing of the glazed partition, i.e. the U-profile, will be hidden from view from anyone looking at the glazed partition as the mounting flanges will cover the gap between the wall elements. The mounting flanges

DK 2018 70142 A1 therefore provide a much better aesthetic appearance of the final wall construction. To provide a further improved aesthetic appearance, the first and second mounting flanges should extend outwards from the end of the first and second side walls, respectively, i.e. the end of the first and second side walls not connected to the end wall.

In an embodiment of the invention, the first and second mounting flanges extend beyond the U-profile in the longitudinal direction at one or both longitudinal ends of the U-profile. A frame element of the invention supporting a first edge of a glazed partition may thereby allow another secondary frame element supporting a second edge perpendicular to the first edge to extend between the first and the second mounting flanges so that its end is hidden from view, whereby an improved aesthetic finish is achieved.

In an embodiment of the invention, each of the first and second mounting flanges has an upwards and back bend fold. By providing the first and second mounting flanges with a fold, attachment of the frame element to adjacent wall elements as described above, can be facilitated as the fold can be adapted to receive and retain an attachment element, e.g. an angle bracket, for connecting the frame element to the adjacent wall elements. The fold thereby allows the attachment element to be attached to the mounting flanges without the use of soldering/welding, screws, rivets or similar, thereby making the installation work easier and potentially enhancing the aesthetic experience of the end user.

The bend of the first and second mounting flanges are formed by bending the respective mounting flanges upwards, i.e. towards the end wall of the U-profile, to form a fold on the surface of the mounting flanges facing away from the glazed partition. This ensures that the fold, like the U-profile, is hidden from view when the frame element of the invention is mounted in the final wall construction. When mounting a glazed partition in a fireshielding wall construction in extension of a two-layered wall structure as described above, it is preferable that the width of the frame element, i.e. the distance between the distal ends of the mounting flanges, corresponds to

DK 2018 70142 A1 the thickness of the two-layered wall, such that, when mounted, the ends of the mounting flanges are substantially flush with the exposed major surface of the respective wall element, to present an aesthetic finish for the final wall construction.

In other embodiments, each of the first and second mounting flanges are bend upwards at an angle of approximately 90-degree to form a side flange extending in the height direction. Such side flanges may substitute an attachment element by providing a surface to interconnect the respective wall elements and side flanges, thereby attaching the frame element to the wall element.

In embodiments wherein the mounting flanges are bent to form a fold, the side flanges are formed in extension of the fold, i.e. the first and second mounting flanges are first bend upwards and back towards the U-profile to form the folds and then upwards at a substantially 90-degree angle to form the side flanges. To provide the best possible attachment between the side flange and the wall element, the two should preferably be in contact. Therefore, in a presently preferred embodiment, the width between the side flanges is adapted to correspond to the distance between the two wall elements of the two-layered wall, i.e. the width of the cavity in the twolayered wall. As the mounting flanges preferably are flush with the major surface facing away from the U-profile of the respective wall elements, this means that in embodiments comprising side flange, the width of the fold of each mounting flange, i.e. the distance between the distal end of the mounting flange and the side wall, which that mounting flange is connected to, minus the distance between the side flange of that mounting flange and the side wall, preferably corresponds to the thickness of the wall elements of the two-layered wall.

In an embodiment of the invention, the side flanges extend beyond the end wall in the height direction. By providing the frame element with side flanges extending higher upwards than the end wall, the frame element gains an increased connection surface, whereby a stronger attachment between the respective side flange and the adjacent wall element is

DK 2018 70142 A1 achieved.

In an embodiment of the invention, a plurality of perforations is formed in either one or both of the side flanges. By providing a U-shaped outer frame element, wherein the side flanges comprise a plurality of perforations, the outer frame element has a smaller heat transfer surface than if it was made without perforations, whereby less heat from a fire will be transferred both from one side of the wall to the other and also from the outer frame element to the glazed partition itself.

Further, the plurality of perforations can absorb deformations occurring in the outer frame element during a fire. This is advantageous because the side of the outer frame element facing the fire, also referred to as the hot side, will deform more than the side of the outer frame element facing away from the fire, also referred to as the cold side. When the outer frame element is able to absorb such deformations, the wall construction is less likely to become unstable and collapse and will thereby slow the rate of spreading of a fire.

The plurality of perforations may be of any desirable shape such as for example circular, rectangular, trapezoid or parallelogram. In some embodiments the perforations are elongate in the longitudinal direction of the outer frame element, thereby providing a good balance between the amount of material available for heat transfer and the strength and stiffness of the outer frame element.

In an embodiment of the invention, each of the side flanges comprises a perforated surface comprising the plurality of perforations and an unperforated surface. The perforated surface preferably extends between the fold and the height of the end wall and the un-perforated surface extends from the perforated surface and upwards in the height direction. By providing the side flanges with both a perforated and an un-perforated surface, the side flanges may achieve the advantages of the perforations explained above, while also achieving and good structural strength.

In a preferred embodiment, a plurality of perforations is formed in the end wall, the first side wall, the second side wall, and/or the part of the

DK 2018 70142 A1 mounting flanges which is folded upwards and back to form the folds. This will further improve the frame element with the advantages described above. While a plurality of perforations could also be formed in the first and/or second mounting flanges to further improve the fire-shielding properties of the frame element, it is often more desirable to omit them as the mounting flanges are often visible in the final wall construction to provide the final wall construction with a more aesthetic appearance.

In some embodiments, the plurality of perforations comprises at least two rows extending in a longitudinal direction of the outer frame element, each row comprising at multiple perforations arranged in series in the longitudinal direction. In some embodiments the perforations of a row are staggered with respect to adjacent perforations of another row. By placing the perforations of a row staggered with respect to the adjacent rows, and so on for each row, the heat transfer path from one side of the wall construction to the other is increased, i.e. the frame element's ability to act as a heat bridge is reduced. This may result in a prolonged time period for the temperature at the cold side of the wall construction to reach a critical level, where people will suffer injuries and material damage will occur. Likewise, sound will have a longer route from one side to the other of the outer frame element.

It is contemplated that the embodiments of the frame element of the first aspect of the invention can be provided without the strips of fire-resistant material, i.e. a frame element wherein the glazed partition is fastened directly by the first and second side walls. Such frame elements may still benefit from the advantage of the other features described above.

In a second aspect, the invention relates to set of parts for a fireshielding wall construction, the set of parts comprising a glazed partition and a fire-shielding outer frame element according to the first aspect of the invention. Such a set of part may be used to assemble a wall construction benefiting from the above-described advantages.

In an embodiment of the invention, the set of parts further comprises at least one angle bracket adapted to be retained in one of the folds of the

DK 2018 70142 A1 first and second mounting flanges and to be attached to a wall element parallel with first and second side walls.

As described further above, one of the legs of the angle bracket may be received and retained in the fold of a respective one of the mounting flanges, while the other leg, which extends in the height direction in relation to the frame element, can extend along the major surface of the adjacent wall element, which faces inwards in the two-layered wall structure, to provide a surface to screw together the wall element and the angle bracket, whereby attachment of the frame element to the wall element can be achieved.

In an embodiment of the invention, the set of parts further comprises a connection element adapted to connect the fire-shielding frame element to another fire-shielding frame element, said connection element comprising a plate adapted to be arranged parallel with a mounting flange and be retained in one of the folds of each of the frame element and the other frame element.

By connecting two consecutive frame elements by the use of a connection element it becomes possible for the frame elements to expand in the longitudinal direction when heated, without losing their ability to support the glazed partitions due to excessive deflection. The same advantage can be achieved for two adjoining glazed partitions as the space between the glazed partitions may allow for possible horizontal movement of the glazed partitions. Furthermore, the use of connection elements to arrange several frame elements in extension of each other in the longitudinal direction may allow longer wall constructions to be constructed.

In an embodiment of the invention, a recess is formed in an edge of the plate of the connection element adapted to face the first or second side wall. By providing such a connection element, a wall construction comprising two consecutive glazed partition may be constructed. In such a wall construction two frame elements are arranged in longitudinal extension of each other and connected by means of one or two connection elements, whereby the frame elements support respective first edges of the glazed partitions. To cover the gap formed between the glazed partitions, i.e. the gap between the two

DK 2018 70142 A1 edges of the glazed partitions perpendicular to the first edges, one or two secondary frame elements may be used to support and cover these edge. Because of the recess in the connection element the secondary frame elements may extend beyond the mounting flanges of the frame elements supporting the first edges. This provides a better sealed wall construction with improved fire-shielding properties and reduced noise transmission.

In an embodiment of the invention, the set of parts further comprises two wall elements for forming a two-layered wall structure in extension of the glazed partition. In such embodiments, the thickness of each wall element is preferably substantially the same as the width of the folds in the width direction, i.e. the distance between the distal end of the mounting flange and the side flange, so that the wall elements can be arranged abutting a respective one of the side flanges and the end of the mounting flanges can be flush with the exposed major surface of the respective wall elements. This will result in a more aesthetic finish, as the mounting flanges may fully cover the U-profile and the ends of the wall elements from view.

In an embodiment of the invention, wherein the fire-shielding outer frame element comprises first and second mounting flanges, the set of parts further comprises at least one mounting tool, said mounting tool comprising a first flange adapted to extend into the cavity, a second flange connected to the first flange at an angle of at least 90-degrees and lower than 180 degrees, and a third flange extending parallel with the first flange, wherein the distance (D) between the first flange and the third flange is substantially the same as the distance in the width direction between the exposed surface of one of strips compressible fire-resistant material and the distal end of the proximate mounting flange.

By providing the set of parts with at least one mounting tool, insertion of the edge of the glazed partition into the cavity may be facilitated. This is achieved by inserting the first flange of the mounting tool into the cavity to cover one of the strips of fire-resistant material before inserting the glazed partition. Because the distance between the first flange and the third flange is substantially the same as the distance in the width direction between the

DK 2018 70142 A1 exposed surface of one of strips compressible fire-resistant material and the end of the mounting flange adjacent to that strip of fire-resistant material, the third flange may engage the end of the mounting flange, so that the mounting tool is “clipped” onto the frame element. This will allow the edge of the glazed partition to be inserted without risking damage to the strip of fire-resistant material and/or the edge itself, after which insertion the mounting tool is removed to allow the strip of fire-resistant material to engage the major surface of the glazed partition.

Alternatively, the distance between the first flange and the third flange is substantially the same as the distance in the width direction between the exposed surface of one of strips compressible fire-resistant material and an exposed surface of an adjacent wall element parallel with the first and second side walls. This will allow the third flange of the mounting tool to engage the wall element, whereby the mounting tool can grip onto the strip of fire-resistant material and the surface of the wall element to remain attached during the insertion of the glazed partition.

The distance (D) is preferably slightly smaller, i.e. approximately 0,1 to 2mm, than the distance in the width direction between the exposed surface of the strip of fire-resistant material and the end of the mounting flange and/or the exposed surface of the adjacent wall element. This will allow the mounting tool to compress the strip of fire-resistant material when the mounting tool is clipped on, thereby facilitating insertion of the glazed partition into the cavity.

The mounting tool(s) is preferably formed from a plastic or metal material and the first flange preferably has a thickness of less than 1mm so that it does not occupy too much room in the cavity during insertion of the glazed partition.

In an embodiment, the angle between the first flange and the second flange of at least one of the mounting tools is between 115 and 155 degrees. Thereby, the second mounting flange will, when the first flange is inserted into the cavity, present a guiding surface slanting towards the center of the cavity, which may guide the edge of the glazed partition into the cavity.

DK 2018 70142 A1

In a third aspect, the invention relates to a method for mounting a fireshielding wall construction, the method comprising the steps of: providing a glazed partition, providing a first fire-shielding outer frame element according to the first aspect of the invention; and inserting a first edge of the glazed partition into the cavity so that the interior surface of the first side wall extends along a first major surface of the glazed partition, and the interior surface of the second side wall extends along a second major surface opposite the first major surface of the glazed partition, wherein the glazed partition is retained between the strips compressible fire-resistant material with a gap between the first edge and the end wall.

In an embodiment of the invention, the method further comprises the step of providing a second fire-shielding outer frame element and inserting a second edge of the glazed partition opposite the first edge of the glazed partition into the cavity of the second frame element so that the interior surface of the first side wall extends along a first major surface of the glazed partition, and the interior surface of the second side wall extends along a second major surface opposite the first major surface of the glazed partition, wherein the glazed partition is retained between the strips compressible fireresistant material with a gap between the second edge of the glazed partition and the end wall.

By supporting both of the opposite first and second edges by means of frame elements according to the first aspect of the invention, the glazed partition may be non-fixedly suspended between the two frame elements, whereby it will be capable of moving in the height and longitudinal directions in relation to the frame elements, i.e. horizontal and vertical movement in relation to the structure the wall construction is built into.

In and embodiment, the method further comprises the step of arranging the two fire-shielding outer frame elements facing each other such that the distance between the end wall of the first frame element and the opening of the U-profile of the second frame element is greater than the distance between the first and second edges of the glazed partition, and such that the distance between the opening of the U-profile of the first frame element and

DK 2018 70142 A1 the opening of the U-profile of the second frame element is smaller than the distance between the first and second edges of the glazed partition, said step being completed before inserting the first and second edges of the glazed partition into the first and second frame elements, respectively.

This is done by completing the step of inserting the first edge into the first frame element to a height in the U-profile which allows the second edge to be inserted into the second frame element, and then moving the glazed partition to its mounted position in the height direction in relation to the first and second frame elements. With this method it becomes possible to install the glazed partition extending between two pre-installed building components, e.g. two wall structures or a roof and a floor, without having to use cover panels, as the first and second frame elements may be built into respective one of the two building components.

In an embodiment of the invention, the method further comprises the steps of at least partially covering the strips of fire-resistant material before inserting the first edge, and optionally the second edge, into the respective frame element, and/or compressing the strips of fire-resistant material in the width direction before inserting the first edge, and optionally the second edge, into the respective frame element; and removing the covering compression after inserting the first edge, and optionally the second edge, into the respective frame element.

A fourth aspect of the invention relates to a fire-shielding wall construction comprising a glazed partition and a first fire-shielding outer frame element according to the first aspect of the invention, said first frame element supporting a first edge of the glazed partition, wherein the glazed partition is retained between the strips of compressible fire-resistant material with a gap between the first edge and the end wall.

Such a wall construction may benefit from the advantages of the frame element of the first aspect of the invention, whereby a wall construction wherein the glazed partition is non-fixedly retained by one or more frame elements. This will allow the glazed partition some degree of vertical and/or horizontal movements in relation to other building components, whereby the

DK 2018 70142 A1 wall construction and the structure into which the wall construction is built may avoid stress caused by either natural movement in the structure, e.g. due to seismic movement or settlement of the structure, or thermal expansion of the building components in the case of fire.

In an embodiment of the invention, the wall construction further comprises a second fire-shielding outer frame element supporting a second edge of the glazed partition opposite to the first edge, wherein the glazed partition is retained between the strips of compressible fire-resistant material of the second frame element with a gap between the second edge and the end wall of the second frame element.

By supporting both of the opposite first and second edges by means of two frame elements according to the first aspect of the invention, the glazed partition may be non-fixedly suspended between the two frame elements, whereby it will be capable of moving in the height and longitudinal directions in relation to the frame element, i.e. horizontal and vertical movement in relation to the structure the wall construction is built into.

In an embodiment of the invention, the wall construction further comprises two parallel wall elements arranged side by side, wherein the first frame element is arranged in a gap between the two parallel wall elements and attached to the two parallel wall elements.

By arranging the frame element between two wall elements, the transition between the wall structure and the glazed partition may be more seamless whereby the wall construction will provide the user/viewer with a more aesthetic finish. Furthermore, as the framing of the glazed partition is hidden in the gap of the wall structure, the glazed partition may extend from the floor to ceiling or between two wall structures without any panels protruding out into the room.

In an embodiment of the invention, the wall construction further comprises a fire-retardant material arranged between the first side wall and the adjacent one of the two parallel wall elements and between the second side wall and the adjacent one of the two parallel wall elements. By providing a fire-retardant material between the side walls and the adjacent one of the

DK 2018 70142 A1 two parallel wall elements the fire-shielding properties of the wall construction may be further improved. The fire-retardant material may be an intumescent material so that it can expand in the case of fire to fill the rooms between the side flanges and the side walls. Or it may be provided by gypsum panels or similar materials, which may increase the structural strength of the wall construction and provide a cooling effect in case of fire.

Detailed description of the invention

In the following, embodiments of the invention will be described in further detail. Each specific variation of the features can be applied to other embodiments of the invention unless specifically stated otherwise. Note that for illustrative purposes the dimensions, especially thicknesses, of the different elements shown may be exaggerated.

Turning now to Figs. 1 and 2, a first embodiment of a frame element 1 of the invention is shown in perspective and cross-sectional views, respectively. The outer frame element 1 is adapted to support a straight edge

DK 2018 70142 A1 of a glazed partition 20, e.g. a top, bottom or side edge of a rectangular glazed partition 20 to form a fire-shielding wall construction 300. To this end, the outer frame element 1 comprises a U-profile, i.e. a profile with a substantially U-shaped cross section. The U-profile is formed by a first side wall 13 and a second side wall 14 which extend in a height direction (H) and are connected to each other at one end by an end wall 12 which extends in a width direction (W) perpendicular to the height direction, whereby the Uprofile defines a cavity 11 for accommodating at least a part of the edge of the glazed partition 20.

When mounted, the glazed partition 20 is inserted into the cavity 11 of the U-profile so that an interior surface 131 of the first side wall 13 extends along a first major surface of the glazed partition 20 and an interior surface 141 of the second side wall 14 extends along a second major surface opposite the first major surface of the glazed partition 20. Each of the interior surfaces 131, 141 are provided with a strip of compressible fire-resistant material 132, 142 which, when the glazed partition 20 is inserted into the cavity 11 engages respective ones of the major surfaces of the glazed partition 20, such that the glazed partition 20 is retained between the first side wall 13 and the second side wall 14. The strips of compressible fireresistant material 132, 142 are arranged with a spacing (S) between them and the end wall 12, so that when the glazed partition 20 is inserted, the strips compressible fire-resistant material 132, 142 may retain it with a gap (G) between the supported edge and the end wall 12.

Because the fire-resistant material 132, 142 is compressible/soft, the glazed partition 20 is not fixedly fastened in the cavity 11 but is capable of moving in the height direction (H) and in the longitudinal direction (L) in relation to the frame element 11. Likewise, this also results in a wall construction 300, wherein the building components are less restricted by each other and therefore allowed some degree of movement in relation to each other. Such movement can be advantageous when the final wall construction 300 is built into a structure with greater settlement than normal or in structures with a large degree of natural movement/vibration, e.g. ships

DK 2018 70142 A1 or other steel/composite structures.

In order to allow the glazed partition 20 to move, the width of the end wall 12 has to be greater than the thickness of the glazed partition 20, i.e. the distance between the major surfaces of the glazed partition 20 which the outer frame element 1 is adapted to support, so that there is a gap between the major surfaces of the glazed partition 20 and the interior surfaces 131, 141. Correspondingly, the distance in the width direction between the exposed surfaces of the fire-resistant material 132, 142 in its natural, uncompressed state should be smaller than the thickness of the glazed partition 20, such that when the glazed partition 20 is inserted into the cavity 11, the strips of fire-resistant material 132, 142 are compressed between a respective one of the interior surfaces 131, 141 and the glazed partition 20, whereby the force exerted on the glazed partition 20 by the fire-resistant material 132, 142 should be sufficient to support and retain the glazed partition 20, while allowing the glazed partition 20 to move when subjected to thermal expansion and/or deflections or settlements in the building.

In the shown embodiment, a plurality of perforations 15 has been formed in the end and side walls 12, 13, 14 of the frame element 1. These perforations 11 result in a significantly longer heat transfer path for thermal energy being transferred from one side of the glazed partition to the opposite. The frame element 1 will therefore have a significantly reduced ability to serve as a heat bridge during a fire.

At the mouth of the U-profile, i.e. the end of the first and second side walls 13, 14 opposite the end wall 12, the side walls 13, 14 have been bend to a 90-degree angle to form a first mounting flange 16 and a second mounting flange 17. The first and second mounting flanges 16, 17 extend outwards in opposite directions in the width direction (W), whereby they enable the frame element 1 to extend between two parallel wall elements 98, 99 of a two-layered wall 90. When mounted in such a wall construction 90, the mounting flanges 16, 17 will span the gap between the two wall elements 98, 99, so that the frame element 1 can be suspended in the gap between the wall elements 98, 99.

DK 2018 70142 A1

The first and second mounting flanges 16, 17 thereby allow the glazed partition 20 to be mounted parallel with and in extension of the two-layered wall 90 to form a wall construction 300. At the same time, the first and second mounting flanges 16, 17 also covers the gap between the two wall elements 98, 98 and hides the U-profile from view, whereby the wall construction 300 achieves a more aesthetically pleasing appearance.

At their respective ends, each of the first and second mounting flanges 16, 17 have been bend upwards and back to a 180-degree angle to form a fold 161, 171 in the respective mounting flange 16, 17. The fold 161, 171 may facilitate connection of the frame element 1 to either another adjacent frame element 1 arranged in extension in the longitudinal direction and/or a wall element 98, 99 as will be described below.

The shown embodiment is further provided with a strip of intumescent material 122 arranged along the interior surface of the end wall 12. In case of fire, the intumescent material 122 may expand to help stabilize the frame element 1 while also prevent or slow the diffusion of hazardous gases developed during a fire between the sides of the final wall construction 300. It should be noted, that a strip of intumescent material 122 can also or alternatively be arranged on the supported edge of the glazed partition 20.

Figs. 3 and 4 show perspective views of the frame element 1 supporting a glazed partition 20. For illustrative purposes, only part of the glazed partition 20 is shown in the Figs. In the shown embodiment, the frame element 1 has been used to support a top edge of the glazed partition 20. The edge of the glazed partition 20 has been inserted into the cavity 11 of the U-profile such that the interior surfaces 131, 141 of the first and the second side walls 13, 14 extend along the edge of the glazed partition 20.

As can be seen in the Figs., the strips of fire-resistant material 132, 142 are arranged at a distance from the end wall 12 so that the glazed partition 20 does not have to be fully inserted, i.e. occupying the full height of the cavity 11, into the U-profile. This provides a gap between the supported edge of the glazed partition 20 and the end wall 12, whereby glazed partition 20 is allowed to move in the height direction (H) in relation to the frame element

DK 2018 70142 A1 and the building components to which the frame element 1 is attached.

In Fig. 3, it can be seen that the edge of the glazed partition 20 perpendicular to the edge supported by the frame element 1 is also supported by a secondary outer frame element 80. The secondary frame element 80 is provided by another frame element according to the first aspect of the invention. By supporting all edges of the glazed partition using frame elements 1 of the invention, the glazed partition 20 will be allowed freedom to move/expand in both the horizontal and vertical direction.

Like the frame element 1 supporting the first edge, the secondary frame element 80 is provided with first and second mounting flanges 816, 817. This allows the secondary frame element 1 to be attached between parallel wall elements 98, 99 of a two-layered wall structure perpendicular to two-layered wall structure 90, in which the frame element 1 supporting the first edge is attached to. Likewise, the edges not shown in the Fig. may also be supported by further frame elements of the invention. When the wall constructions 300 comprises multiple glazed partitions, the edges of the glazed partition, which terminate towards other glazed partitions will be supported by cover elements (not shown) which cover the gaps between adjacent glazed partitions.

Fig. 5 shows an example of the frame element 1 described above with dimensions given in mm. These dimensions are exemplary, and the frame element 1 of the invention is not limited to the shown dimensions. The frame element 1 is adapted to support a glazed partition with a thickness of about 20mm. The width of the cavity 11 of the U-profile is 26mm so that the Uprofile is 6mm wider than the glazed partition 20, whereby a gap of 3mm is formed between a respective one of the first and second side walls 13, 14 and the major surfaces of the glazed partition 20. The frame element 1 has been bent, molded, or extruded so that it is formed in one piece.

Fig. 6 show a cross-sectional view of the frame element 1 shown in Fig. 5 in a wall construction 300. The wall construction 300 comprises two parallel wall elements 98, 99 of a two-layered wall structure 90 with a gap between the two parallel wall elements 98, 99. Because of the first and second

DK 2018 70142 A1 mounting flanges 16, 17, the frame element 1 of the shown embodiment is capable of being installed between the two wall elements 98, 99, whereby the glazed partition 20 can be mounted in extension of the wall structure 90 to form the wall construction 300.

In the shown embodiment, the wall elements 98, 99 are made from a rigid concrete material. When mounting the frame element 1, a number of angled brackets 163, 173 are inserted under the folds 161, 171, through which angled brackets 163, 173 the frame element 1 is connected, e.g. by means of screws, to the adjoining wall element 98, 99 on both sides of the glazed partition 22. The gaps formed between the steel plates and the adjacent side wall 12, 13 are both fitted with power board 96, 07, i.e. a fireretardant material/fire-resistant mineral board. In general, such a fireretardant material may be provided in all embodiments of the invention.

Figs. 7 and 8 show a frame element 1 from a top and an end view. The shown embodiment further comprises two connection elements 60 adapted to connect the frame element 1 to another adjoining frame element so that several glazed partitions 20 can be arranged in extension of each other. The connection element 1 comprises a plate made from a rigid material, preferably metal, which can extend between the two adjoining frame elements to bridge the gap between them and connect them to each other.

The connection element 60 is attached to the frame element 1 by arranging it on top, i.e. adjacent the height direction, one of the first or second mounting flanges 16, 17 and inserting it into a respective fold 161, 171 of that mounting flange 16, 17. The connection element 60 may thereby extend beyond the end of the mounting flange 16, 17 and be attached to the adjoining frame element 1 in the in an identical manner.

In the shown embodiment, a recess 61 has been formed in each of the connection elements 60. The recess 61 is formed in the edge of the connection element 60 which is arranged facing the side walls 13, 14 to allow the cover frame element (not shown) mentioned above to extend between the mounting flanges 16, 17 and beyond the mounting flanges 16, 17 of the frame element 1. This not only provides an aesthetic improvement as the

DK 2018 70142 A1 ends of the cover element will be hidden, but also stabilizes the cover element and thereby the second edge of the glazed partition.

To stabilize the connection element 60, a part of the first side wall 13 has been bent outwards to form a stabilizing flange 134 extending down towards the first mounting flange 16 with a directional component in the height and width direction (H, W). When arranged, the connection element will be retained at one edge by the fold 161 of the mounting flange 16 and at the opposite edge between the stabilizing flange 134 and the first mounting flange 16. Likewise, the second side wall 14 also comprises a stabilizing flange 144 to stabilize the connection element 60 arranged at the second mounting flange 14.

The frame element 1 of the shown embodiment further comprises multiple angle brackets 163, 173 adapted to attach the frame element 1 to the wall elements 98, 99 of a wall structure 90. The angle brackets 163, 173 are preferably used when attaching the frame element 1 to wall structures 90 made from concrete or similar, as such wall structures 90 are rigid, compared to e.g. wall structures made from gypsum, and require a limited contact surface to provide a stable attachment between the frame element 1 and the wall elements 98, 99.

Turning now to Figs. 9 and 10, another embodiment of the frame element 1 is shown from a perspective and a cross-sectional view respectively. The frame element 1 is similar to the frame element 1 described above, but it differs in that the angle brackets 163, 173 have been replaced with a set of side flanges 162, 172 extending upwards in the height direction (H). The side flanges 162, 172 have been formed integrally with a respective one of the first or second mounting flange 162, 172 by bending the fold 161, 171 upwards to a 90-degree angle

The side flanges 162, 172 make the shown embodiment more suited for being interconnected to less rigid wall elements, e.g. gypsum plasterboard, as the increased contact surface, compared to angle brackets 163, 173, help achieve increased connection strength and structural stability. The side flanges 162, 172 extend beyond the height of the end wall 12, so

DK 2018 70142 A1 that the contact surface between the side flanges 162, 172 and the wall elements 98, 99 can be further increased to improve the strength of the interconnection between the two.

The folds 161, 171 and the parts of the side flanges up to the height of the end wall 12 have been provided with a plurality of perforations 15 perforated to the same pattern as the U-shaped part. The advantage of these perforations 15 are explained above. Furthermore, by leaving an upper part of the side flanges 162, 172, i.e. the part above the end wall 12, unperforated, the side flanges 162, 172 may gain an increased stiffness and structural strength.

Figs. 11 and 12 show the frame element 1 described above supporting a glazed panel 20. Like Fig. 3 and 4, the frame element 1 extend along a first edge of the glazed partition 20 so that the edge is retained and supported in the cavity 11 of the frame element 1 in a manner allowing some degree of movement and/or thermal expansion.

A second edge perpendicular to the first edge is supported with a secondary frame element 80 like the one shown in Fig. 3. This secondary frame element 80 further comprises a plurality of perforations 15 giving the secondary frame element 80 the above-described advantages.

Fig. 13 shows a particular embodiment of the frame element with dimensions given in mm. These dimension are only exemplary and the embodiments comprising side flanges 162, 172 are not limited to these dimensions. In order to present an improved aesthetic finish, the mounting flanges 16, 17 should not extend wider than the wall elements 98, 99 and preferably extend as far as the exposed major surface of the wall elements 98, 99. At the same time, the wall elements 98, 99, e.g. gypsum plasterboard, should also be in contact with the side flanges 162, 172 to ensure a good interconnection between the two. The width of the wall elements 98, 99 should therefore be substantially the same as the width (Wf) of the folds 162, 172. As mentioned above, the height (Hf) of the side flanges 162, 172 is greater than the height (Hsw) of the side walls 13, 14 to increase the contact surface between the side flanges 162, 172 and the wall elements

DK 2018 70142 A1

98, 99.

Fig. 14 shows the frame element 1 in a wall construction 300, supporting an edge of a glazed partition 20. The wall construction 300 comprises a two-layered wall structure 90 with two parallel wall elements 98, 99 of gypsum plasterboard. On the side of the two side flanges 162, 172 facing the U-profile a fire-retardant material provided by another gypsum panel 96, 97 is fixated. This provides both structural strength and provides a cooling effect on the wall construction 300 in case of fire.

As is shown in Fig. 6, wall constructions 300 comprising frame elements 1 of the invention not having side flanges 162, 172 may also be provided with a fire fire-retardant material 96, 97, e.g. a gypsum panel. In such fire-shielding wall constructions 300, the fire-retardant material will be arranged between the wall elements 98, 99 and the proximate of the first and second side walls 13, 14.

Turning now to Fig. 15, a first mounting tool 30 adapted to direct the glazed panels 20 into place without damaging the glass, the fire-resistant material 132, 142 or the first or second side walls 13, 14 is shown. The mounting tool 30 is a thin plate, preferably made from metal, bent or formed into an angled shape which can be clipped onto a mounting flange 16, 17 of the frame element 1 prior to inserting the glazed partition 20.

The mounting tool 30 shown in Fig. 9 is adapted for directing the top edge of the glazed partition into position in a frame element 1. In the shown Fig. the dimensions of the mounting tool 20 is shown in mm. These lengths are for one embodiment of the mounting tool 20 and can be varied depending on the dimensions of the frame element 1, i.e. the height of the first and second side walls 13, 14 and the width of the mounting flanges 16, 17 and the fire-resistant material 132, 142, and the thickness of the glazed partition 20.

The mounting tool 30 comprises a first flange 31 which during mounting of the glazed partition 20 is inserted into the cavity 11 to extend along and cover at least a part of the width of the fire-resistant material 132, 142 so that the glazed partition 20 does not damage the fire-resistant material 132,

DK 2018 70142 A1

142 when the glazed partition 20 is inserted. The first flange 31 should not be too wide, preferably thinner than 1mm, so that when inserted into the cavity 11 it will not occupy too much space in the width direction (W).

The mounting tool 30 further comprises a second flange 32 connected to the first flange 31. The angle between the first flange 31 and the second flange

In the shown embodiment, the mounting tool 30 comprises a slanting portion 33 which, when the mounting tool 30 is clipped on to mount the glazed partition 20, are slanting, leading towards the center of the U-profile to provide a guiding surface to direct the edge of the glazed partition 20 into the U-profile.

Figs. 17 and 18 show a second and a third mounting tool 40, 50 respectively. The two different mounting tools 40, 50 are adapted to, in collaboration be used to insert a bottom edge of the glazed panel 20 into a frame element 1, by clipping the second mounting tool 40 onto one of the first or the second mounting flange 16, 17 and clipping the third mounting toll 50 onto the other one of the first or the second mounting flange 16, 17.

The second mounting tool 40 differs from the first mounting tool 30 in that the first flange 41 is longer. When the second mounting tool 40 is clipped on to a mounting flange and the first flange 41 is inserted into the cavity 11 of the frame element 1, the first flange 41 will rise above the mounting flange, which the second mounting tool 40 is clipped onto, to present a vertical abutment surface which the glazed partition will abut when pivoted into alignment with the cavity 11.

The third mounting tool 50 differs from the first mounting tool 30 in that the second flange 52 is very short, so that when the first flange 51 is fully inserted into the cavity 11, the second mounting flange 52 will be on level with the mounting flange, which the third mounting tool 50 is clipped onto. This will give the glazed panel 20 better space to be pivoted into alignment with the cavity 11, as the third mounting tool 50 will not rise above the mounting flange.

Using two first, a second, and a third mounting tool 30, 40, 50, the

DK 2018 70142 A1 method of assembling the wall construction 300 is as illustrated in Figs. 16 and 19, showing a bottom and a top edge, respectively, of a glazed partition 20 in a wall construction 300. The initial step of assembling the wall construction 300 will be arranging a frame element 1 in the gap between the wall elements 98, 99 of two opposing two-layered wall structures 90, and attaching the mounting flanges 16, 17 to respective wall elements 98, 99 such that the openings of the U-profiles are facing each other. The dimensions of the glazed partition 20 should be such, that the distance between a first edge and a second edge is greater than the distance between the openings of the U-profile but smaller than the distance from the opening of the U-profile of the bottom frame element 1 to the end wall 12 of the top frame element 1.

The subsequent step will be to clip on the mounting tools 30, 40, 50 to prepare the frame elements 1 for insertion of the glazed partition 20. On the top frame element 1, two first mounting tools 30 are clipped on, one on each of the first and second mounting flange 16, 17. On the bottom frame element 1, a second mounting tool 40 and a third mounting tool 50 is clipped onto the second and first mounting flange 17, 16, respectively. The mounting tools 30, 40, 50 will thus at least partially cover the strips of fire-resistant material 132, 142, and preferably compress the strips of fire-resistant material 132, 142 against the side wall 13, 14.

In order to support the weight of the glazed partition 20 the bottom frame element 1 may be provided with a support element 111 which fills the gap formed between the second edge of the glazed partition 20 and the end wall 12 of the bottom frame element 1. While this may limit the downwards vertical movement of the glazed partition 20 it will prevent the glazed partition 20, which is usually provided by a heavy single- or multi-layer glass panel, from falling down to the end wall 12 of the bottom frame element 1. The support element 111 is provided by a fire-resistant block capable of withstanding the weight of the glazed partition 20 without deforming. Such materials can be Polyvinylchloride or similar polymers. Alternatively, the support element 111 can be made from metal.

DK 2018 70142 A1

Subsequent the step of clipping on the mounting tools 30, 40, 50, the method comprises the step of inserting the glazed partition into the top and bottom frame elements 1. This is done by first inserting the first edge into the cavity 11 of the top frame element 1. To facilitate this, the slanting second flanges 32 of the first mounting tools 30 may be used as a guide surface to direct the edge into the cavity 11. When in the cavity 11, the first edge is inserted higher into the cavity 11, i.e. the first edge is brought closer to the end wall 12, then the final position of the glazed partition 20 in the height direction. This allows the glazed partition to be pivoted into a vertical position where it will abut the first flange 41 of the second mounting tool 40, whereby the worker assembling the wall construction 300 may know when to lower the glazed partition 20. The second edge of the glazed partition 20 is then inserted into the cavity 11 of the bottom frame element 1 by displacing the glazed partition vertically downwards to its mounted position.

The subsequent step is then to remove the mounting tools 30, 40, 50, whereby the strips of fire-resistant material 132, 142 can engage the major surfaces of the glazed partition 20 so that the glazed partition is non-fixedly retained by the frame elements 1. This method may also be used, to insert the glazed partition 20 into frame elements 1 arranged to support the side edges of the glazed partition 20.

When three edges of the glazed partition 20 are to be supported by frame elements of the invention, the method described above will first be used to insert the glazed partition 20 into the top and bottom frame elements

1. The glazed partition 20 may then be displaced horizontally into one of the frame elements 1, preferably provided with mounting tools as described above, arranged to support one of the side edges. Alternatively, the method described above may be used to insert the glazed partition into the side frame elements and then vertically displacing the glazed partition into a top or bottom frame element 1.

When multiple glazed partitions 20 are to be mounted, the steps for inserting two opposing edges are repeated for each glazed partition 20. The two glazed partitions 20 which terminate in a wall structure 90 may further

DK 2018 70142 A1 be inserted into a side frame element. The edges between adjacent glazed partitions will then be covered and/or supported by cover elements as described above. For such wall constructions 300 it is preferred that an individual frame element 1 is used for the top and bottom edge of each 5 glazed partition 20. Adjacent glazed partitions 1 will then be connected by connection elements 60 which will allow the cover frame elements to extend between each individual frame element 1. It should be noted, that while the connection element 60 is shown in Figs. 7 and 8 in connection with the first described embodiment of the frame element 1, the connection element 60 10 may also be used with other embodiments of the frame element 1, e.g. the embodiments shown in Figs. 9 to 14.
