Definitions
- the invention relates to a building element according to the preamble of the appended claim 1.
- the invention relates to such building elements that contain frame profiles, either stationary frame profiles or frame profiles arranged in connection with a pivotable, for example glazed glazing element.
- glazed building elements metal frame profiles are utilized in which glass elements are attached by means of seals or the like.
- Such elements equipped with glass in which the glass element is surrounded by a metal profile frame, can include for example doors, windows as well as stationary structures, such as facade structures.
- the term building element refers either to an element that is installed separately to a building, or to a stationary part of a building, which can be constructed in situ.
- the glazed building element can be hinged pivotable in a stationary building element that contains a frame formed of frame profiles and surrounding the pivotable element.
- Aluminium is a preferred metal raw material for frame profiles because of its workability (forming of profiles by means of extrusion), strength and light weight. Because of the relatively low melting temperature of aluminium when compared to steel, great deal of attention has been paid to the fire protection of such elements. Therefore different kinds of additional materials are utilized in order to protect the aluminium parts from heat, so that the aluminium parts would fulfil the requirements set by the desired fire-resistance class.
- thermal breaks are commonly used in frame profiles, i.e. the frame profile is in a way constructed of two profile parts that are connected together by means of a structure with poorer thermal conductivity, for example by means of plastic strips.
- One of the profile parts is located on one side of the building element (in the case of an outer wall, door or a window, either outdoors or in-doors) and the other is located on the opposite side of the building element, the thermal breaks between the profile parts thus preventing the heat transmission through the building element at the location of the frame in a direction perpendicular to the plane of the building element.
- the thermal breaks can also be used in elements located in the interiors of buildings, because it is not desirable in general that heat is transmitted too easily between two spaces.
- the glass element is normally attached to the frame profile in such a manner that both profile parts have seals or the like that are pressed against the outer surfaces of the glass element from opposite sides.
- the thermal breaks constitute the weakest point in the frame structure.
- the frame should endure a predetermined time in the fire.
- the thermal breaks melt or burn off, the frame structure can no longer remain coherent, and for example the glass element is easily detached, which results in that the capability of the building element to function as a temporary fire-insulating structure is significantly impaired.
- the glazed building element according to the invention is primarily characterized in what will be presented in the characterizing part of the appended claim 1.
- Both profile parts of the building element contain at least one longitudinal so-called screw groove that opens up in the direction of the main plane of the element.
- the screw grooves can be located on both edges of the frame structure. Besides to screw down the fastening screws, it is possible to utilize the screw grooves to form fastening points for other elements or materials that improve the fire resistance properties of the structure.
- an additional fastener that is fastened to both profile parts connected by the thermal breaks.
- the same fastener can also be used for keeping the plate-like element in the building element, such as a glass element, in its place at its edge.
- the additional fastener has better heat resistance than the thermal breaks, it keeps the profile parts together, in other words holds the frame profile together, even if the thermal breaks were destroyed, and it can be utilized further to hold the plate-like element in its place in the frame profile.
- the additional fastener is, however, designed in such a manner that it does not significantly increase the heat conduction between the profile parts.
- the additional fasteners can for example be elements that are short in relation to the length of the frame profile, said additional fasteners being placed at set intervals throughout the length of the edge of the sheet-like element.
- the additional fastener can be designed simple in structure.
- the additional fastener may contain fastening parts protruding towards the profile parts, which fastening parts can be utilized for fastening the additional fastener to the screw grooves in the profile parts. It can also contain two projecting parts protruding towards the plate-like element, between which parts it is possible to clamp the edge of the element, said projecting parts thus forming a gripping part.
- the fastening parts attachable to the profile parts and the possible projecting parts of the gripping part that are intended for the plate-like element can be formed by bending them of the same sheet-like blank on the opposite sides.
- Fig. 1 shows the structure of a building element that is hinged pivotable, and can be a door or a window, at the location of the frame profile 1 on the side of the hinge.
- the pivotable building element comprises a frame located in a particular plane, said frame surrounding a plate-like element that is parallel to this plane, which element is a glass element in the description hereinbelow.
- the plate-like element can also be another element, and the structures described hereinbelow can also be applied in other building elements than glazed building elements.
- the metal frame profile 1 is fastened pivotably by means of a hinge 6 to the frame profile 1 of a stationary structure that is also made of metal.
- the stationary frame profile 1 forms a part of the frame structure surrounding the pivotable building element.
- a glass element 2 is fastened in a known manner so that on both sides of the glass element 2 there are rigid sealing profiles 7 carrying seals.
- the edge of the glass element 2 is positioned between the sealing profiles 7, in which elastic seals 8 that are pressed against the outer surfaces of the glass element 2 from opposite sides are attached.
- the sealing profiles 7 are attached with a positively locking so-called snap coupling to the corresponding profile parts 3 that are interconnected with a thermal break structure 4.
- the thermal break structure is composed of strips or the like that extend perpendicularly to the main plane of the glazed building element (plane of the glass element 2).
- the strips extend in the longitudinal direction of the frame profile and their thicker longitudinal edges are positioned within anchoring grooves located on the inwardly facing sides of the profile parts 3.
- the thermal break structure may also contain several strips, but it is common to all thermal break structures to form a connecting structure between the profile parts 3, in which the heat-transfer coefficient is smaller when compared to a situation in which the thermal breaks were replaced with strips of identical cross-section and being of the same metal material as the profile parts 3.
- the thermal break strips 4a, 4b can be made of for example plastic, that is advantageously reinforced, for example of glass fibre reinforced polyamide or glass fibre reinforced resin.
- the stationary frame profile 1 also comprises profile parts 3 similar to the profile parts 3 of the frame profile of the pivotable structure, said profile parts being connected with a thermal break structure 4.
- Fig. 1 also shows a securing element 9 located between the frame profile 1 and the stationary frame profile 1.
- a number of such securing elements are located at fixed intervals in the longitudinal direction of the frame profile.
- the securing elements do not constitute a part of the invention, and therefore they are not discussed in more detail in this context.
- the profile parts 3 are hollow profiles having a rectangular general cross-section.
- the material of these parts is especially light metal, such as aluminium, of which the profile parts can be manufactured by means of extrusion.
- the first shorter side of the cross-section of the profile part constitutes a section of the inner edge of the frame profile that is located on the side of the glass element 2, and the other shorter side forms a section of the outer edge of the frame profile that will be positioned opposite to the stationary frame profile.
- Separate profile parts 3 that are attached together by means of the thermal break structure 4 are located on opposite sides of the main plane of the building element, i.e. when seen from the side of the space limited by the building element, one profile part 3 is located inside and the other one outside.
- the hinge 6 is fastened to one of the profile parts 3 of the frame profile.
- Both profile parts 3 comprise a screw groove 10 that is included in the profile shape (uniform cross-sectional shape) and opens up in the direction of the plane of the glass element 2.
- the screw groove 10 in located inward (towards the thermal break structure) from a wide fastening groove 21 of the profile part that is intended for fastening the sealing profile 7.
- the screw groove 10 is thus located in the cross-section approximately at the corner of the rectangle.
- the screw grooves 10 are continuous grooves extending in the longitudinal direction of the profile part 3, and it is characteristic to them that screws screwed down therein fasten well, irrespective of the location in which they are placed in the longitudinal direction of the groove.
- the walls of the grooves have such a surface topography formed of successive notches in the depth direction that it holds a screw screwed therein at any point of the screw groove in its place by means of positive locking, but the walls can also be smooth-faced.
- the dimensions of the screw groove are typically such that its opposite walls are parallel to each other, and its depth is greater than its width (distance between the walls), typically at least 1.5 times the width, advantageously at least 2 times the width.
- screw groove 10 On the opposite side of the profile part 3, i.e. on the side of the outer edge of the assembled frame profile 1, there is also a screw groove 10 that opens in parallel with the plane of the glass element, but opens away from the glass element. In the assembled frame profile 1 of the pivotable building element these screw grooves open towards the opposite inner edge of the stationary frame profile 1. These screw grooves 10 are located, in a direction perpendicular to the plane of the glass element 2, approximately at the same point with the screw grooves 10 of the glass element side, thus opening in the opposite direction with respect to the latter.
- the screw grooves 10 open towards a space 14 that is limited by the surface of the inner edge of the opposite stationary frame profile 1 and in the direction perpendicular to the plane of the glass element by the projecting parts 13 functioning as extensions to the outer walls of the longer sides of the hollow profile parts 3, said projecting parts 13 comprising grooves which receive seals 11, which seal the space when the door is closed.
- the space is sealed by the projecting part 13 of the profile part 3 in the frame profile 1 and its seal 11, and on the other side by the projecting part 13 of the profile part 3 located on the opposite side of the stationary frame profile 1 and its seal 11.
- the screw grooves 10 accommodate thermally swellable material, it is capable of filling the above-described space between the profile parts 1 and closing the space in a fire-proof manner in case of a fire. It is typical for such a fire protection material that it expands into a multiple volume when a given threshold temperature is attained, and as an example it is possible to mention a product available under the commercial name INTUMEX LSK.
- the fire protection material can be placed in the grooves as a continuous, band-like material. If profile parts 3 similar to the ones used in the pivotable frame profile 1 are used in the stationary frame profile 1 as well, the screw grooves 10 located therein also enter in contact with the aforementioned space 14, and are located opposite to the screw grooves of the pivotable frame profile 1, as shown in Fig. 1 . Thus, it is also possible to use these screw grooves to place the above-described fire protection material, and they can function together with the opposite screw grooves 10, wherein better efficiency is attained.
- Fig. 1 also shows how it is also possible to use the screw grooves filled with fire protection material to fasten screws 12 by means of which it is possible to fasten securing elements 9 and their counter elements to the outer edge of the pivotable frame profile 1 and to the inner edge of the stationary frame profile 1.
- the fire protection material can be located in the area between the screws 12 in the screw grooves 10.
- two parallel continuous screw grooves 10 that extend over the entire length of the profile are each provided on both edges of the frame profile 1 after the profile parts 3 have been connected.
- These screw grooves can be used in an appropriate manner either to fasten special fasteners directly by pressing or to place materials or to screw up other parts belonging to the structure by means of screws.
- the screw groove 10 extends in the profile part 3 in its depth direction, in other words parallelly to the longer sides of the profile part 3, from the outer surface constituting the shorter side of the profile part inside the fastening point (anchoring groove) of the thermal break strip 4a.
- the screw groove 10 increases the distance between the outer surface of the profile part 3 and the fastening point of the thermal break strip 4a in the metal material of the profile part.
- the building element also includes an additional fastener 5 having a better heat resistance than the thermal break structure 4.
- the additional fastener 5 is attached at least to both profile parts 3.
- the additional fastener 5 connects the profile parts 3 to each other in a manner that is independent of the thermal break structure 4.
- the cohesion of the profile parts 3 is not completely dependent on the thermal break strips. If the additional fastener 5 is designed in such a manner that the edge of the glass element 2 facing the frame profile is attached thereto, the glass element 2 also remains in the frame structure, even if for example the seals 8 and the parts 7 carrying the seals were damaged or destroyed.
- the additional fastener 5 contains a gripping part 5a to which the edge of the glass element 2 is attached by means of a clamp connection.
- the gripping part 5a is composed of two projecting parts protruding towards the glass element, between which projecting parts the glass plate is clamped. The projecting parts are pressed against the outer surfaces of the glass element 2 in the area between the outer edge of the glass element and the seals 8.
- the additional fastener 5 is attached to both profile parts 3 by means of fastening parts 5b protruding in the opposite direction, i.e. towards the frame profile 1.
- the fastening parts 5b are shaped in such a manner that they are positively locked to the screw grooves 10 located in the profile parts 3 and opening towards the glass element 2.
- the end of the projecting part 5b is bent in the shape of a hook, so that it would be locked in the wall of the screw groove, in a suitable notch in its surface topography.
- the thermal break 4a on the side of the glass element 2 does not have to be ensured similarly to the thermal break 4b located close to the outer edge of the frame profile 1 (because of the mounting of the securing element 9 located on the outer edge of the frame profile, said mounting fastening the profile parts 3 together at this edge).
- the additional fastener 5 that is located between the thermal break 4a of the inner edge of the frame profile 1 and the glass element 2 is thus especially advantageous for ensuring the cohesion of the frame profile.
- Fig. 1 also shows that the additional fastener also contains a base part 5c located between the thermal break 4 and the outer edge of the glass element 2, perpendicularly to the main plane of the glazed building element (the plane of the glass element 2). Both ends of the base part 5c contain fastening parts 5b attached to the corresponding profile parts, and projecting parts protrude therefrom in the direction of the glass element 2, said projecting parts forming the gripping part 5a for the glass element.
- Fig. 1 also shows an additional fastener 5 placed on the side of the outer edge of the stationary frame profile, said additional fastener taking hold of the screw grooves 10 and connecting the profile parts 3 similarly to the additional fastener located by the glass element, but this additional fastener only contains fastening parts 5b.
- Fig. 2 show the structure of a pivotable, glazed building element at the location of a vertical frame profile 1 located on the opposite edge.
- the assembly of the frame profile, the location of the screw groove 10, the attachment of the glass element 2 to the frame profile 1, the structure of the additional fastener 5 and the way it is attached to the glass element 2 and to the profile parts 3 located on both sides of the plane of said glass element, as well as the structure of the frame profile 1 and its screw grooves 10 are similar to those shown in Fig. 1 .
- seals 11 that seal the door gap, said seals being attached to projecting parts 13 similar to the ones shown in Fig. 1 .
- a closed space 14 is also formed, to which screw grooves that are filled with the intumescent fire protection material 15 whose properties have been discussed above, open up both from the stationary frame profile 1 and from the pivotable frame profile 1.
- the screw grooves 10 located in the pivotable frame profile 1 and the screw grooves 10 located in the stationary frame profile can also be used for attaching the parts of a lock with screws to the outer edge of the pivotable frame profile 1 and to the inner edge of the stationary frame profile 1, respectively.
- the intumescent fire protection material 15 can be seen in the pivotable frame profile 1. Screws 12 are visible in the screw grooves 10 of the stationary frame profile, but the fire protection material can be located in the screw grooves in the section between the screws.
- Figs. 3 and 4 show the structure of Fig. 2 at a different point in the longitudinal direction of the profiles.
- a fastener is 16 placed behind the thermal break strip 4b located at the outer edge of the pivotable profile 1, i.e. in the cavity between the thermal break strips 4a, 4b.
- the fastener is seated in the recesses formed on the outer surfaces of the profile parts 3 remaining inside the frame profile.
- the fastener 16 keeps the profile parts 3 together, and it constitutes a part of the fastening system of a lock introduced between the profile part 3, the front panel and the fastening screw of said fastening system being also shown in the figure.
- Fig. 4 shows the intumescent material 15 in all screw grooves 10 that open up to the space 14.
- Fig. 5 shows another glazed building element according to the invention, which in this case is a stationary structure, for example a stationary wall.
- the frame structure also surrounds a plate-like element, which in the description hereinbelow is a glass element, but the structures can also be applied to other elements besides glazed building elements.
- the profile parts 3 are connected with a thermal break structure 4 similar to the one shown in Figs 1 and 2 .
- the glass elements 2 are fastened to both edges of the frame profile 1, at each edge by means of seals 8 positioned against the glass from opposite sides of the glass element, said seals being placed in the seal parts 7.
- each edge of the frame profile there are screw grooves 10 on both sides of the thermal break structure 4 and the above-described additional fasteners 5 to fasten the profile parts 3 together by this edge, and to ensure the attachment of the corresponding glass element 2.
- the structure of the frame profile 1 is mirror-symmetrical in relation to the symmetry plane perpendicular to the plane of the building element.
- Fig. 6 shows the profile parts 3 of Fig. 5 that are connected together, without additional parts or materials.
- the profile parts 3 that have identical shapes and sizes, i.e. that are of the same profile.
- Fig. 7 shows in perspective the structure of the additional fastener 5 and its attachment to both profile parts 3 for the sake of clarity without the glass element 2.
- the material of the additional fastener 5 is a plate-like blank, and projecting parts forming the gripping part 5a of the glass element 5a, and fastening parts 5b of the profile parts are bent from both ends of said blank, wherein the unbent part in the middle forms the base part 5c. Because of the location of the screw grooves 10 and the glass element 2, the projecting parts forming the gripping part 5a are bent at a point closer to the middle, and the base part 5c extends straight on both sides thereof further towards the ends, and ends up in the fastening parts 5b bent to the other direction.
- the base part 5c may be provided with one or more areas having a weaker heat transmission capacity across the frame profile 1 than the material of the additional fastener 5.
- the area is simply formed into an opening 20, which can be implemented in the blank material by means of simple manufacturing techniques.
- Fig. 7 also shows that the range of the additional fastener 5 in the longitudinal direction of the frame profile 1 is quite small, wherein it does not significantly increase heat transmission between the profile parts 3.
- Such additional fasteners can be placed in separate pieces over the length of the frame profile spaced at fixed intervals, for example at intervals of approximately 25 to 30 cm.
- the additional fastener 5 can also lack the gripping part 5a for the glass element. In this case it only contains fastening parts 5b bent on one side of the unbent base part 5c. Over the length of the frame profile it is also possible to place the aforementioned fasteners 5 of different types at suitable intervals, some of said fasteners only attaching the profile parts 3 together and some of them also attaching the glass element 2 to the frame structure, in addition to connecting the profile parts 3.
- the better heat resistance of the additional fastener 5 compared to the thermal break structure 4 can be easily implemented by manufacturing the additional fastener 5 of a material that has a higher melting temperature, softening temperature or decomposition temperature than the material of the thermal break structure 4.
- the elevated temperature at which the thermal break loses its capability to retain the frame structure together either due to melting, softening or decomposition (e.g. burning) does not affect the additional fastener 5 in any of the aforementioned mechanisms in such a manner that the fastening capability of said additional fastener would be impaired.
- the thermal break strips 4a, 4b are made of plastic, which is common because of the poor heat conductivity of plastic, the additional fastener 5 is thus advantageously made of metal, advantageously steel.
- An advantageous manufacturing material of the additional fastener 5 is stainless steel, which has poor heat conductivity, and especially if the glazed building element is an element isolating the outdoor air and the interior from each other, such as an entrance door, an openable outer window or a glazed outer wall, its resistance to corrosion is an advantageous feature.
- the additional fastener 5 is manufactured of a blank by means of bending, the blank is thus made of a suitably thick metal plate, such as a steel plate, especially of a stainless steel plate.
- filling material that promotes the fire protection and prolongs the resistance of the profile parts 3 in case of a fire, especially by preventing the rising of temperature.
- This filling material is marked with broken lines 22 in Fig. 4 .
- the material can be a thermally insulating material, and for example material that releases crystal water under heat, such as gypsum.
- the screw grooves 10 are sufficiently deep, it is possible to extend the fastening parts 5b protruding from the base part of the additional fastener 5 to surround the filling material 22 on both sides and to keep the filling material 22 in its place by means of said fastening parts, even if the profile part 3 on the hotter side had melted. Thus, the filling material still will be present to protect the undamaged profile part 3 that has remained in the fire on the cooler side.
- the filling material 22 is placed only in the central chamber, but there may also be filling material inside the cavities of the profile parts 3 in addition to the central chamber.
- the frame profiles in which the above-described screw grooves and additional fasteners are located do not have to be completely vertical or horizontal, but they can also be positioned in an inclined position, depending on the structure of the building element and, in the case of stationary walls, also on architectural solutions.
- the figures show a glass element composed of one glass plate, but it is also possible to use a double or multiple so-called insulating glass.
- the term glass element refers to all elements that are transparent and/or the purpose of which is to give a visual impression of a glass.
- the glass element can be replaced with another element that isolates two spaces from each other and that has another purpose than to create a visual connection or a visual impression of a glass.
- a plate-like element can be for example a gypsum board clad with metal plates, which resists heat well and is especially suitable for fire-proof doors.

Abstract
Description
- The invention relates to a building element according to the preamble of the appended
claim 1. The invention relates to such building elements that contain frame profiles, either stationary frame profiles or frame profiles arranged in connection with a pivotable, for example glazed glazing element. - In glazed building elements metal frame profiles are utilized in which glass elements are attached by means of seals or the like. Such elements equipped with glass, in which the glass element is surrounded by a metal profile frame, can include for example doors, windows as well as stationary structures, such as facade structures. Hence, in this context the term building element refers either to an element that is installed separately to a building, or to a stationary part of a building, which can be constructed in situ. The glazed building element can be hinged pivotable in a stationary building element that contains a frame formed of frame profiles and surrounding the pivotable element.
- Aluminium is a preferred metal raw material for frame profiles because of its workability (forming of profiles by means of extrusion), strength and light weight. Because of the relatively low melting temperature of aluminium when compared to steel, great deal of attention has been paid to the fire protection of such elements. Therefore different kinds of additional materials are utilized in order to protect the aluminium parts from heat, so that the aluminium parts would fulfil the requirements set by the desired fire-resistance class.
- Another problematic property of aluminium is its good thermal conductivity. Because of this, so-called thermal breaks are commonly used in frame profiles, i.e. the frame profile is in a way constructed of two profile parts that are connected together by means of a structure with poorer thermal conductivity, for example by means of plastic strips. One of the profile parts is located on one side of the building element (in the case of an outer wall, door or a window, either outdoors or in-doors) and the other is located on the opposite side of the building element, the thermal breaks between the profile parts thus preventing the heat transmission through the building element at the location of the frame in a direction perpendicular to the plane of the building element. The thermal breaks can also be used in elements located in the interiors of buildings, because it is not desirable in general that heat is transmitted too easily between two spaces.
- In the case of a glazed building element, the glass element is normally attached to the frame profile in such a manner that both profile parts have seals or the like that are pressed against the outer surfaces of the glass element from opposite sides.
- In the case of a fire, the thermal breaks constitute the weakest point in the frame structure. The frame should endure a predetermined time in the fire. When the thermal breaks melt or burn off, the frame structure can no longer remain coherent, and for example the glass element is easily detached, which results in that the capability of the building element to function as a temporary fire-insulating structure is significantly impaired.
- In the design of frame profiles, attention has up until present been paid primarily to the fastening points of the seals and the attachment of the thermal breaks. When the aim is to attach different parts or materials, the frame profiles must be equipped with the necessary parts either in connection with the manufacture, or they must be worked during installation.
- As an example of frame profiles equipped with thermal breaks that can be used in glazed building elements in particular, it is possible to mention publications
EP 590 236 EP 1 024 243DE 3438861 . The first-mentioned publication discloses the placement of plate-like materials made of thermally swellable material on the surface of the profile and the latter two disclose special securing elements that connect the profile parts of the frame profile in case the thermal breaks are destroyed. - It is an aim of the invention to eliminate the aforementioned drawbacks and to present a building element that can be used in a versatile manner in fireproof structures for improved fire protection and/or fire resistance. Another aim of the invention to present a building element that can remain intact for a longer period of time in case of fire, even though some parts of the same are destroyed under the effect of heat. To attain this purpose, the glazed building element according to the invention is primarily characterized in what will be presented in the characterizing part of the appended
claim 1. - Both profile parts of the building element contain at least one longitudinal so-called screw groove that opens up in the direction of the main plane of the element. The screw grooves can be located on both edges of the frame structure. Besides to screw down the fastening screws, it is possible to utilize the screw grooves to form fastening points for other elements or materials that improve the fire resistance properties of the structure.
- To the frame profile of the building element it is possible to attach an additional fastener that is fastened to both profile parts connected by the thermal breaks. The same fastener can also be used for keeping the plate-like element in the building element, such as a glass element, in its place at its edge. Because the additional fastener has better heat resistance than the thermal breaks, it keeps the profile parts together, in other words holds the frame profile together, even if the thermal breaks were destroyed, and it can be utilized further to hold the plate-like element in its place in the frame profile.The additional fastener is, however, designed in such a manner that it does not significantly increase the heat conduction between the profile parts. The additional fasteners can for example be elements that are short in relation to the length of the frame profile, said additional fasteners being placed at set intervals throughout the length of the edge of the sheet-like element.
- The additional fastener can be designed simple in structure. The additional fastener may contain fastening parts protruding towards the profile parts, which fastening parts can be utilized for fastening the additional fastener to the screw grooves in the profile parts. It can also contain two projecting parts protruding towards the plate-like element, between which parts it is possible to clamp the edge of the element, said projecting parts thus forming a gripping part.
- An especially advantageous structure is attained by manufacturing the additional fastener of a straight blank material. The fastening parts attachable to the profile parts and the possible projecting parts of the gripping part that are intended for the plate-like element can be formed by bending them of the same sheet-like blank on the opposite sides.
- It is also possible to utilize the screw grooves to place the thermally swellable fire protection material substantially over the entire length of the frame profile. The edge of the profile looks tidy when the material is located in the grooves. A special advantage is attained by means of this solution because the material reacts faster to heat since it is surrounded by metal on three sides, the temperature of said metal rising rapidly in case of a fire. Thus, the expansion and sealing occurs faster.

Fig. 1 shows the structure of a building element that is hinged pivotable, and can be a door or a window, at the location of theframe profile 1 on the side of the hinge. The pivotable building element comprises a frame located in a particular plane, said frame surrounding a plate-like element that is parallel to this plane, which element is a glass element in the description hereinbelow. The plate-like element can also be another element, and the structures described hereinbelow can also be applied in other building elements than glazed building elements. - The
metal frame profile 1 is fastened pivotably by means of ahinge 6 to theframe profile 1 of a stationary structure that is also made of metal. Thestationary frame profile 1 forms a part of the frame structure surrounding the pivotable building element. To theframe profile 1 of the pivotable element, aglass element 2 is fastened in a known manner so that on both sides of theglass element 2 there arerigid sealing profiles 7 carrying seals. The edge of theglass element 2 is positioned between thesealing profiles 7, in whichelastic seals 8 that are pressed against the outer surfaces of theglass element 2 from opposite sides are attached. Thesealing profiles 7 are attached with a positively locking so-called snap coupling to thecorresponding profile parts 3 that are interconnected with athermal break structure 4. Here, the thermal break structure is composed of strips or the like that extend perpendicularly to the main plane of the glazed building element (plane of the glass element 2). The strips extend in the longitudinal direction of the frame profile and their thicker longitudinal edges are positioned within anchoring grooves located on the inwardly facing sides of theprofile parts 3. There are two thermal break strips 4a, 4b, one close to theglass element 2 and the other close to thestationary frame profile 1. The thermal break structure may also contain several strips, but it is common to all thermal break structures to form a connecting structure between theprofile parts 3, in which the heat-transfer coefficient is smaller when compared to a situation in which the thermal breaks were replaced with strips of identical cross-section and being of the same metal material as theprofile parts 3. The thermal break strips 4a, 4b can be made of for example plastic, that is advantageously reinforced, for example of glass fibre reinforced polyamide or glass fibre reinforced resin. - As can be seen in
Fig. 1 , thestationary frame profile 1 also comprisesprofile parts 3 similar to theprofile parts 3 of the frame profile of the pivotable structure, said profile parts being connected with athermal break structure 4. -
Fig. 1 also shows a securing element 9 located between theframe profile 1 and thestationary frame profile 1. A number of such securing elements are located at fixed intervals in the longitudinal direction of the frame profile. The securing elements do not constitute a part of the invention, and therefore they are not discussed in more detail in this context. - The
profile parts 3 are hollow profiles having a rectangular general cross-section. The material of these parts is especially light metal, such as aluminium, of which the profile parts can be manufactured by means of extrusion. In the frame profile of the pivotable structure, the first shorter side of the cross-section of the profile part constitutes a section of the inner edge of the frame profile that is located on the side of theglass element 2, and the other shorter side forms a section of the outer edge of the frame profile that will be positioned opposite to the stationary frame profile. - In the following, the structure of the
frame profile 1 of the pivotable glazed building element is described in more detail. -
Separate profile parts 3 that are attached together by means of thethermal break structure 4 are located on opposite sides of the main plane of the building element, i.e. when seen from the side of the space limited by the building element, oneprofile part 3 is located inside and the other one outside. Thehinge 6 is fastened to one of theprofile parts 3 of the frame profile. - Both
profile parts 3 comprise ascrew groove 10 that is included in the profile shape (uniform cross-sectional shape) and opens up in the direction of the plane of theglass element 2. Thescrew groove 10 in located inward (towards the thermal break structure) from awide fastening groove 21 of the profile part that is intended for fastening thesealing profile 7. Thescrew groove 10 is thus located in the cross-section approximately at the corner of the rectangle. When the profile parts are connected together with thethermal break structure 4, thescrew grooves 10 are located in the frame profile on both sides of the middle plane of theglass element 2 and inside the seal profiles 7. Thescrew grooves 10 are continuous grooves extending in the longitudinal direction of theprofile part 3, and it is characteristic to them that screws screwed down therein fasten well, irrespective of the location in which they are placed in the longitudinal direction of the groove. To improve the fastening, the walls of the grooves have such a surface topography formed of successive notches in the depth direction that it holds a screw screwed therein at any point of the screw groove in its place by means of positive locking, but the walls can also be smooth-faced. The dimensions of the screw groove are typically such that its opposite walls are parallel to each other, and its depth is greater than its width (distance between the walls), typically at least 1.5 times the width, advantageously at least 2 times the width. - On the opposite side of the
profile part 3, i.e. on the side of the outer edge of the assembledframe profile 1, there is also ascrew groove 10 that opens in parallel with the plane of the glass element, but opens away from the glass element. In the assembledframe profile 1 of the pivotable building element these screw grooves open towards the opposite inner edge of thestationary frame profile 1. These screwgrooves 10 are located, in a direction perpendicular to the plane of theglass element 2, approximately at the same point with thescrew grooves 10 of the glass element side, thus opening in the opposite direction with respect to the latter. Thescrew grooves 10 open towards aspace 14 that is limited by the surface of the inner edge of the oppositestationary frame profile 1 and in the direction perpendicular to the plane of the glass element by the projectingparts 13 functioning as extensions to the outer walls of the longer sides of thehollow profile parts 3, said projectingparts 13 comprising grooves which receive seals 11, which seal the space when the door is closed. On the side of thehinge 6, the space is sealed by the projectingpart 13 of theprofile part 3 in theframe profile 1 and itsseal 11, and on the other side by the projectingpart 13 of theprofile part 3 located on the opposite side of thestationary frame profile 1 and itsseal 11. - When the
screw grooves 10 accommodate thermally swellable material, it is capable of filling the above-described space between theprofile parts 1 and closing the space in a fire-proof manner in case of a fire. It is typical for such a fire protection material that it expands into a multiple volume when a given threshold temperature is attained, and as an example it is possible to mention a product available under the commercial name INTUMEX LSK. The fire protection material can be placed in the grooves as a continuous, band-like material. Ifprofile parts 3 similar to the ones used in thepivotable frame profile 1 are used in thestationary frame profile 1 as well, thescrew grooves 10 located therein also enter in contact with theaforementioned space 14, and are located opposite to the screw grooves of thepivotable frame profile 1, as shown inFig. 1 . Thus, it is also possible to use these screw grooves to place the above-described fire protection material, and they can function together with theopposite screw grooves 10, wherein better efficiency is attained. -
Fig. 1 also shows how it is also possible to use the screw grooves filled with fire protection material to fastenscrews 12 by means of which it is possible to fasten securing elements 9 and their counter elements to the outer edge of thepivotable frame profile 1 and to the inner edge of thestationary frame profile 1. The fire protection material can be located in the area between thescrews 12 in thescrew grooves 10. - When the
screw grooves 10 are located on both edges of theprofile part 3, two parallelcontinuous screw grooves 10 that extend over the entire length of the profile are each provided on both edges of theframe profile 1 after theprofile parts 3 have been connected. These screw grooves can be used in an appropriate manner either to fasten special fasteners directly by pressing or to place materials or to screw up other parts belonging to the structure by means of screws. - As to
Fig. 1 , it can also be mentioned that thescrew groove 10 extends in theprofile part 3 in its depth direction, in other words parallelly to the longer sides of theprofile part 3, from the outer surface constituting the shorter side of the profile part inside the fastening point (anchoring groove) of thethermal break strip 4a. Thus, it is possible to reduce the heat transmission even further, because thescrew groove 10 increases the distance between the outer surface of theprofile part 3 and the fastening point of thethermal break strip 4a in the metal material of the profile part. - The building element also includes an
additional fastener 5 having a better heat resistance than thethermal break structure 4. Theadditional fastener 5 is attached at least to bothprofile parts 3. Thus, theadditional fastener 5 connects theprofile parts 3 to each other in a manner that is independent of thethermal break structure 4. Hence, the cohesion of theprofile parts 3 is not completely dependent on the thermal break strips. If theadditional fastener 5 is designed in such a manner that the edge of theglass element 2 facing the frame profile is attached thereto, theglass element 2 also remains in the frame structure, even if for example theseals 8 and theparts 7 carrying the seals were damaged or destroyed. - The
additional fastener 5 contains agripping part 5a to which the edge of theglass element 2 is attached by means of a clamp connection. Thegripping part 5a is composed of two projecting parts protruding towards the glass element, between which projecting parts the glass plate is clamped. The projecting parts are pressed against the outer surfaces of theglass element 2 in the area between the outer edge of the glass element and theseals 8. Theadditional fastener 5 is attached to bothprofile parts 3 by means offastening parts 5b protruding in the opposite direction, i.e. towards theframe profile 1. Thefastening parts 5b are shaped in such a manner that they are positively locked to thescrew grooves 10 located in theprofile parts 3 and opening towards theglass element 2. The end of the projectingpart 5b is bent in the shape of a hook, so that it would be locked in the wall of the screw groove, in a suitable notch in its surface topography. - The
thermal break 4a on the side of theglass element 2 does not have to be ensured similarly to thethermal break 4b located close to the outer edge of the frame profile 1 (because of the mounting of the securing element 9 located on the outer edge of the frame profile, said mounting fastening theprofile parts 3 together at this edge). Theadditional fastener 5 that is located between thethermal break 4a of the inner edge of theframe profile 1 and theglass element 2 is thus especially advantageous for ensuring the cohesion of the frame profile. -
Fig. 1 also shows that the additional fastener also contains abase part 5c located between thethermal break 4 and the outer edge of theglass element 2, perpendicularly to the main plane of the glazed building element (the plane of the glass element 2). Both ends of thebase part 5c containfastening parts 5b attached to the corresponding profile parts, and projecting parts protrude therefrom in the direction of theglass element 2, said projecting parts forming thegripping part 5a for the glass element. -
Fig. 1 also shows anadditional fastener 5 placed on the side of the outer edge of the stationary frame profile, said additional fastener taking hold of thescrew grooves 10 and connecting theprofile parts 3 similarly to the additional fastener located by the glass element, but this additional fastener only containsfastening parts 5b. -
Fig. 2 show the structure of a pivotable, glazed building element at the location of avertical frame profile 1 located on the opposite edge. Here, the assembly of the frame profile, the location of thescrew groove 10, the attachment of theglass element 2 to theframe profile 1, the structure of theadditional fastener 5 and the way it is attached to theglass element 2 and to theprofile parts 3 located on both sides of the plane of said glass element, as well as the structure of theframe profile 1 and itsscrew grooves 10 are similar to those shown inFig. 1 . - Between the
frame profile 1 of the pivotable element and theframe profile 1 of the stationary structure there areseals 11 that seal the door gap, said seals being attached to projectingparts 13 similar to the ones shown inFig. 1 . At the door gap, aclosed space 14 is also formed, to which screw grooves that are filled with the intumescentfire protection material 15 whose properties have been discussed above, open up both from thestationary frame profile 1 and from thepivotable frame profile 1. - The
screw grooves 10 located in thepivotable frame profile 1 and thescrew grooves 10 located in the stationary frame profile can also be used for attaching the parts of a lock with screws to the outer edge of thepivotable frame profile 1 and to the inner edge of thestationary frame profile 1, respectively. InFig. 2 , the intumescentfire protection material 15 can be seen in thepivotable frame profile 1.Screws 12 are visible in thescrew grooves 10 of the stationary frame profile, but the fire protection material can be located in the screw grooves in the section between the screws. -
Figs. 3 and4 show the structure ofFig. 2 at a different point in the longitudinal direction of the profiles. InFig. 3 , a fastener is 16 placed behind thethermal break strip 4b located at the outer edge of thepivotable profile 1, i.e. in the cavity between the thermal break strips 4a, 4b. The fastener is seated in the recesses formed on the outer surfaces of theprofile parts 3 remaining inside the frame profile. At this point thefastener 16 keeps theprofile parts 3 together, and it constitutes a part of the fastening system of a lock introduced between theprofile part 3, the front panel and the fastening screw of said fastening system being also shown in the figure.Fig. 4 shows theintumescent material 15 in all screwgrooves 10 that open up to thespace 14. -
Fig. 5 shows another glazed building element according to the invention, which in this case is a stationary structure, for example a stationary wall. Similarly to the pivotable building element, here the frame structure also surrounds a plate-like element, which in the description hereinbelow is a glass element, but the structures can also be applied to other elements besides glazed building elements. Theprofile parts 3 are connected with athermal break structure 4 similar to the one shown inFigs 1 and2 . Theglass elements 2 are fastened to both edges of theframe profile 1, at each edge by means ofseals 8 positioned against the glass from opposite sides of the glass element, said seals being placed in theseal parts 7. At each edge of the frame profile there arescrew grooves 10 on both sides of thethermal break structure 4 and the above-describedadditional fasteners 5 to fasten theprofile parts 3 together by this edge, and to ensure the attachment of the correspondingglass element 2. The structure of theframe profile 1 is mirror-symmetrical in relation to the symmetry plane perpendicular to the plane of the building element. In the structure ofFig. 5 , there may be aglass element 2 only on one side, and the structure of the opposite side of the frame profile is thus similar to the structure of the stationary profile part shown inFig. 1 . -
Fig. 6 shows theprofile parts 3 ofFig. 5 that are connected together, without additional parts or materials. To form theframe profile 1, it is possible to utilize theprofile parts 3 that have identical shapes and sizes, i.e. that are of the same profile. -
Fig. 7 shows in perspective the structure of theadditional fastener 5 and its attachment to bothprofile parts 3 for the sake of clarity without theglass element 2. As can be seen in the drawing, the material of theadditional fastener 5 is a plate-like blank, and projecting parts forming thegripping part 5a of theglass element 5a, andfastening parts 5b of the profile parts are bent from both ends of said blank, wherein the unbent part in the middle forms thebase part 5c. Because of the location of thescrew grooves 10 and theglass element 2, the projecting parts forming thegripping part 5a are bent at a point closer to the middle, and thebase part 5c extends straight on both sides thereof further towards the ends, and ends up in thefastening parts 5b bent to the other direction. The figure also shows that to reduce the heat transmission, thebase part 5c may be provided with one or more areas having a weaker heat transmission capacity across theframe profile 1 than the material of theadditional fastener 5. In this case the area is simply formed into anopening 20, which can be implemented in the blank material by means of simple manufacturing techniques. In the figure there are twoopenings 20 successively in the longitudinal direction of theframe profile 1. -
Fig. 7 also shows that the range of theadditional fastener 5 in the longitudinal direction of theframe profile 1 is quite small, wherein it does not significantly increase heat transmission between theprofile parts 3. Such additional fasteners can be placed in separate pieces over the length of the frame profile spaced at fixed intervals, for example at intervals of approximately 25 to 30 cm. - As was mentioned above, the
additional fastener 5 can also lack thegripping part 5a for the glass element. In this case it only containsfastening parts 5b bent on one side of the unbentbase part 5c. Over the length of the frame profile it is also possible to place theaforementioned fasteners 5 of different types at suitable intervals, some of said fasteners only attaching theprofile parts 3 together and some of them also attaching theglass element 2 to the frame structure, in addition to connecting theprofile parts 3. - The better heat resistance of the
additional fastener 5 compared to thethermal break structure 4 can be easily implemented by manufacturing theadditional fastener 5 of a material that has a higher melting temperature, softening temperature or decomposition temperature than the material of thethermal break structure 4. Thus, the elevated temperature at which the thermal break loses its capability to retain the frame structure together either due to melting, softening or decomposition (e.g. burning), does not affect theadditional fastener 5 in any of the aforementioned mechanisms in such a manner that the fastening capability of said additional fastener would be impaired. If the thermal break strips 4a, 4b are made of plastic, which is common because of the poor heat conductivity of plastic, theadditional fastener 5 is thus advantageously made of metal, advantageously steel. An advantageous manufacturing material of theadditional fastener 5 is stainless steel, which has poor heat conductivity, and especially if the glazed building element is an element isolating the outdoor air and the interior from each other, such as an entrance door, an openable outer window or a glazed outer wall, its resistance to corrosion is an advantageous feature. When theadditional fastener 5 is manufactured of a blank by means of bending, the blank is thus made of a suitably thick metal plate, such as a steel plate, especially of a stainless steel plate. - Because of the design and fastening method of the
additional fastener 5, it can be easily pressed down from outside said profile parts in its place in theprofile parts 3 connected through thethermal break structure 4. - In the central chamber in the middle of the
frame structure 1, remaining inside theprofile parts 3 and the thermal break strips 4a, 4b, it is possible to place filling material that promotes the fire protection and prolongs the resistance of theprofile parts 3 in case of a fire, especially by preventing the rising of temperature. This filling material is marked withbroken lines 22 inFig. 4 . The material can be a thermally insulating material, and for example material that releases crystal water under heat, such as gypsum. If thescrew grooves 10 are sufficiently deep, it is possible to extend thefastening parts 5b protruding from the base part of theadditional fastener 5 to surround the fillingmaterial 22 on both sides and to keep the fillingmaterial 22 in its place by means of said fastening parts, even if theprofile part 3 on the hotter side had melted. Thus, the filling material still will be present to protect theundamaged profile part 3 that has remained in the fire on the cooler side. - In
Fig. 4 , the fillingmaterial 22 is placed only in the central chamber, but there may also be filling material inside the cavities of theprofile parts 3 in addition to the central chamber. - The invention is not restricted to the embodiments described above, but it can be modified on the basis of the inventive idea presented in the claims. Although the description hereinabove primarily describes the screw grooves and additional fasteners provided in connection with the vertical frame profiles of the frame of a glazed building element and the stationary frame surrounding the same, there may be screw grooves and additional fasteners also in the other, horizontal frame profiles of the frame surrounding the glass element and the stationary frame surrounding this frame, if they are made of the
profile parts 3 shown inFigs 1 to 3 . The frame profiles in which the above-described screw grooves and additional fasteners are located, do not have to be completely vertical or horizontal, but they can also be positioned in an inclined position, depending on the structure of the building element and, in the case of stationary walls, also on architectural solutions. Similarly, it is possible to utilize the invention in such glazed building elements that isolate two spaces located in the interior of a building from each other, for example in pivotable doors or windows or in stationary partition walls that exist between two rooms, as well as in building elements isolating the outdoor air and the interior of a building from each other, i.e. in entrance doors, in openable windows and outer walls. The figures show a glass element composed of one glass plate, but it is also possible to use a double or multiple so-called insulating glass. The term glass element refers to all elements that are transparent and/or the purpose of which is to give a visual impression of a glass. - The glass element can be replaced with another element that isolates two spaces from each other and that has another purpose than to create a visual connection or a visual impression of a glass. Such a plate-like element can be for example a gypsum board clad with metal plates, which resists heat well and is especially suitable for fire-proof doors.
