The building element

The invention relates to a building element according to the preamble of claim 1. The invention relates to building elements of the type having frame profiles, either fixed frame profiles or frame profiles arranged in connection with a pivotable glazing element, for example.

10 Glazed building elements use metal frame profiles to which the glass elements are attached by means of seals or the like. Such glazed elements in which the glazing element is surrounded by a metal profile frame can be doors, windows and also solid structures, for example facade structures. Thus, in this context, a building element refers to either a separate element to be installed in the building or a fixed part of the building which may be constructed on site. The glazed building element may be hinged to a pivoting solid building element having a frame surrounding the pivoting element consisting of frame profiles.

20

As a metal raw material for frame profiles, aluminum is popular for its easy machinability (extrusion molding), good strength and light weight. Relative to aluminum steel! due to the low heat of melting, much attention has been paid to the fire protection of such elements. As a result, aluminum parts are sought to be protected from heat by various additional materials, v to meet the requirements of the desired fire rating.

Another difficult feature of aluminum is its high thermal conductivity. As a result, the so-called frame profiles are commonly used in frame profiles. heat breaks, that is to say, the frame profile is sorted out of two profile sections,. which are joined together by a poorly conductive structure, for example plastic strips. One of the profile sections is on one side of the • · building element (in the case of an exterior wall, door or window: 35 on either the outdoor or indoor side) and the other on the opposite side of the • • building element, and heat breaks between against the plane of the building element - 113077 2 straight through the building element at the frame. Heat breaks can also be used in the elements inside buildings because it is generally not desirable for heat to be transferred too easily between two spaces.

5

In the case of a glazed building element, the glass element is normally attached to the frame profile such that each profile section has seals or the like which press against the outer surfaces of the glass element on opposite sides.

10

In case of fire, heat loss is the weakest point in the frame structure. The frame should last a certain amount of time in case of fire. As the heat breaks melt or burn, the frame structure is no longer stable and the glass element, for example, is easily detached, causing the building element's ability to act as a temporary fire barrier structure to be severely impaired.

So far, the design of the frame profiles has primarily taken into account the attachment points of the gaskets and the attachment of heat breaks. 20 If different parts or materials are to be attached, the frame profiles must be fitted with the necessary parts either during manufacture or during machining.

As examples of frame profiles with thermal breaks, which can be used specifically in glazed building elements, EP 590 236, EP 1 024 243 and DE 3438861 can be mentioned. Firstly, the positioning of sheet-like pieces of heat-swellable material is known, and of the two rigid ones, special securing bodies are known which connect the profile sections of the frame profile 30 in case heat breaks are destroyed.

The object of the invention is to eliminate the above drawbacks and to provide a building element which can be used in a wide variety of fire-resistant structures for improving fire protection and / or fire resistance. The object of the invention is also to provide a building element which is a combustion chamber; · The jet may remain intact for some time despite the fact that some of its parts: • are destroyed by heat. To accomplish this purpose, the glazed building element according to the invention is essentially characterized in what is set forth in the characterizing part of the appended claim 1.

5 Each profile section of the building element has at least one so-called longitudinal section. a screw groove extending parallel to the main plane of the element and further comprising at least one additional fastener which engages at least both profile sections with their screw grooves. The screw grooves may be on either side of the frame structure. The screw grooves 10 can, in addition to being used for screwing fastening screws, provide fastening points for other elements or materials which improve the fire properties of the structure.

A further 15 fasteners can be attached to the frame profile of the building element by means of screws, which attach to both profile sections connected by heat traps. The same fastener can also be used to hold a plate-like element in the building element, such as a glass element, at its edge. Because the additional fastener has better heat resistance than heat breaks, it holds the profile portions together, i.e., the size of the frame profile 20, despite the loss of heat loss, and can still hold the plate-like element in place in the frame profile. The additional fastener is designed so that it does not, however, significantly increase heat conduction between the profile sections. For example, the additional fasteners may be short pieces relative to the length of the frame profile, spaced at regular intervals along the edge of the plate-like element.

| The additional fastener can be constructed with a simple structure. Auxiliary: The fastener may have fasteners extending in the direction of the profile portions, which can be utilized to attach the additional fastener to the screw grooves in the profile 30 portions. It may also have two projections projecting in the direction of the plate-like element, between which the edge of the element may be compressed, thereby forming an engaging portion.

»· '··· *. A particularly simple construction is obtained by forming an additional clamp: 35 of straight blank material. The fasteners that attach to the profile members and: · *: any gripping projections for the plate-like element • · · • ♦ 113077 4 can be formed by bending them to the opposite sides of the same plate-like blank.

The screwdriver can also be used to place the heat-expandable fire-protective material over substantially the entire length of the frame profile. The edge of the profile will look neat with the material in the grooves. A particular advantage of this solution is that the material reacts faster to heat because it is surrounded by a metal on three sides, the temperature of which increases rapidly in a fire situation. In this way, swelling and condensation occur faster.

Other preferred embodiments of the invention are set forth in the dependent claims and in the description below.

The invention will now be described in more detail with reference to the accompanying drawings, in which Figure 1 shows a structure of a hinged side of a pivoting hinged element against a frame profile in a straight section, Figure 2 shows the opposite edge of the same building element; another view, [Fig. 4 shows the structure of Fig. 3 from a third position: Fig. 5 shows a structure of a fixed building element in a perpendicular to the frame profile 30, Fig. 6 shows a frame profile without additional parts in cross-section, and : ··: As a perspective view.

Fig. 1 shows the structure of a hinged building element, which may be a door or a window, at the hinge-side frame profile 1. The pivoting building element has a frame located on a certain plane which surrounds a plate-like element 5 parallel to this plane, which in the following description is a glass element. The plate-like element may be another element, and the structures described below may also be applied to non-glazed building elements.

The metal frame profile 1 is attached via a hinge 6 to pivot 10 to a fixed structure frame profile 1 which is also metal. The fixed frame profile 1 is part of the frame structure surrounding the pivoting building element. A glass element 2 is fastened to the frame profile 1 of the pivoting element in a known manner such that on both sides of the glass element 2 there are sealing rigid sealing profiles 7 between which the edge of the glass 15 element 2 sits and with elastic seals 8 The sealing profiles 7 are fastened with a so-called locking mechanism. by a snap-on connection to the respective profile portions 3 connected by the heat-break structure 4. The heat-break structure is formed in this perpendicular to the main plane of the glazed structural element (glass plane 2) or the like. The strips extend in the longitudinal direction of the frame profile, and their thicker longitudinal edges are located inside the fastening grooves on the turned sides of the profile sections 3. There are two heat break lists 4a, 4b, one near the glass element 2 and one near the fixed frame-25 profile 1. The heat break structure may have more than one list, but common to all heat break structures is to form an interconnection between the profile portions 3 with a lower the holding would have the same strips of metal material of profile sections 3. The heat-shrink strips 30 4a, 4b may be, for example, plastic which is preferably reinforced, for example '·': fiberglass reinforced polyamide or fiberglass reinforced resin.

As shown in Fig. 1, the fixed frame profile 1 also has profile sections 3 similar to the profile sections 3 of the pivoting frame profile, which: '': 35 are connected by a heat break structure 4.

»· · 113077 6

Fig. 1 also shows a locking piece 9 located between the pivoting element frame profile 1 and the fixed frame profile 1, which are spaced apart in the longitudinal direction of the frame profile 1 and are not further described herein without reference to the invention.

The profile sections 3 are generally rectangular cross-sectional hollow sections. Their material is especially light metal such as aluminum, from which the profile parts can be made by dropping. In the frame profile of the pivoting structure, the first shorter side of the section portion 10 of the profile portion forms part of the inner edge of the frame profile which is on the side of the glass element 2 and the second shorter side on the other side forms part of the outer edge of the frame profile.

The structure of the frame profile 1 of the pivotable glazing building element will now be described in more detail.

Separate profile portions 3 interconnected by heat break structure 4 are located on opposite sides of the main plane of the glazed building element, i.e. when viewed from the space defined by the structural element, one profile part 3 is inside and the other outside. The hinge 6 is secured to one of the profile sections 3 of the frame profile.

: Each profile section 3 has a screw groove 10 of a profile shape (standard cross-sectional shape) which opens in the direction • of the glass element 2 • j. The screw groove 10 is located inwardly (toward the heat sink structure i) of the wide fastening groove 21 of the profile section for fastening the sealing profile 7. The screw groove 10 is thus located in a cross-section approximately at the corner of the rectangle. When the profile portions 3 are joined together by a heat interruption structure 4, the screw grooves 10 in the frame profile are located on either side of the central plane of the glass element 2 and sealing. inside the profiles 7. The screw grooves 10 are continuous grooves extending in the longitudinal direction of the profile part 3, characterized in that the screws threaded thereon hold well, no matter where they are positioned in the T: 35 direction. In order to improve adhesion, their walls have a * · · surface shape formed by successive notches in the groove that holds the screw 113077 7 screwed in any position in the groove, but the walls can also be smooth. The dimensions of the screw groove are typically such that its opposite walls are parallel and have a depth greater than the width (distance between the walls), typically at least 1.5 times the width, preferably at least 2 times the width.

The profile part 3 further has a screw groove 10 on the opposite side, i.e. on the outer edge of the assembled frame profile 1, also parallel to the plane of the glass element but away from the glass element, these screw grooves open towards the opposite fixed frame profile 1. These screw grooves 10 are located perpendicular to the plane of the glass element 2 at approximately the same position as the screw grooves 10 on the side of the glass element 2, opening in the opposite direction to them. The screw grooves 10 open into a space 14 delimited by an inner surface of the fixed frame profile 1 opposite to the projections 13 extending on the outer sides of the longer sides of the cavity profile portions 3, perpendicular to the plane of the glass element. The space 20 is closed by a projection 13 and a gasket 11 of the profile part 3 of the hinged frame profile 1, and on the other side by a projection 13 and a gasket 11 of the profile part 3 on the opposite side of the fixed frame profile 1.

When heat-swellable material 25 is placed in the screw groove 10, it is able to fill the space between the profile sections 1 described above and to seal it in an insulating manner in the event of a fire. Such a fire protection material is characterized by a multiplication in volume when a certain threshold temperature is reached, for example, the product obtained under the trade name INTUMEX LSK. The fire-30 protective material can be placed in the grooves as a continuous strip-like material. If the same profile sections 3 are used in the fixed frame profile 1 as in the swivel frame profile 1, the screw grooves 10 therein also communicate with the aforementioned space 14 and are located ···. end the screw groove of the pivoting frame profile 1 as shown in Figure 1.

»· ///,. Hereby, these screwdrivers 10 may also be used to accommodate the fire protection material described above, and may cooperate with the opposing screws 10, thereby providing improved performance.

• · 113077 8

Figure 1 further illustrates how a screw-filled fire-retardant screw can also be used to fasten screws 12 for securing securing members 9 and their counterparts to the outer edge of the pivotable frame profile 1 and to the inner edge of the fixed frame profile 1. The body protection material may be in the area between the screws 12 in the screw grooves 10.

When the screw grooves 10 are located at both edges of the profile portion 3, two adjacent continuous screw grooves 10 extending substantially along the entire profile length are obtained after joining the profile portions 3, which can be conveniently used to either directly attach special fasteners or screws 15 of screws.

1, the screw groove 10 extends in its depth direction, i.e. in the direction of the long sides of the profile portion 3, from the outer surface forming the shorter side of the profile portion to the inside of the fastening point (fastening groove). In this way, the heat transfer by conduction can be reduced already, since the screw groove 10 increases the distance between the outer surface of the profile part 3 and the attachment point of the heat cut-off strip 4a in the metal material of the profile part.

»· '25 The building element further comprises an additional fastener 5 which has better heat resistance than the heat dissipation structure 4. The additional fastener 5 engages. ·, At least both profile sections 3. The additional fastener 5 thus connects the profile sections 3 .v'; independent of the heat break structure 4, whereby the retention of the profile sections 3 is not completely dependent on the heat break bars. * · · '30 If the additional fastener 5 is formed such that the edge of the frame profile side of the glass element 2 engages therewith, the glass: ·: element 2 will remain in the frame structure despite, for example, the seals :: 8 and supporting parts 7 being damaged or destroyed.

. *. *. * .: 35 The additional fastener 5 has a gripping part 5a to which the edge of the glass element 2 is clamped. The gripping part 5a consists of two projections projecting in the direction of the la-element, between which the glass sheet I · · »· 113077 9 crosses. The projections press against the outer surfaces of the glass element 2 in the region between the outer edge of the glass element and the seals 8. The additional clamp 5 engages both profile sections 3 in opposite directions, i.e. with fastening parts 5b extending in the direction of the frame profile 1. The fastening members 5b are shaped such that they engage in a form-locking manner in the screw grooves 10 in the profile portions 3 which open in the direction of the glass element 2. The end of the projection 5b is bent to lock into the corresponding groove of its surface.

The heat break 4a on the side of the glass element 2 need not be secured in the same way as the heat break 4b near the outer edge of the frame profile 1 (due to the fitting of the securing piece 9 on the outer edge of the frame profile The additional fastener 5, which is located between the heat break 4a on the inner edge 15 of the frame profile 1 and the glass element 2, is of particular benefit in order to ensure that the frame profile is held together.

Figure 1 also shows how the auxiliary fastener has a base portion 5c which is located between the heat break 4 and the outer edge of the glass element 2 towards-20 directly opposite the direction of the main plane of the glazed building element (plane 2 of the glass element). At each end of the base portion 5c there are fastening portions 5b engaging the respective profile portions and extending therefrom in the direction of the glass element 2 to form the engaging portion 5a for the glass element.

There is also a closed space 14 on the door aperture. -5 grooves 10 filled with an expandable fire protection material 15, the properties of which are described above.

The screw groove 10 in the pivoting frame profile 1 and the screw groove 10 in the fixed frame profile can also be used to fasten the lock parts 10 to the outer edge of the pivoting frame profile 1 and the inner edge of the fixed frame profile 1 respectively. Fig. 2 shows the expandable fire protection material 15 visible in the pivoting frame profile 1. The fixed frame profile screw groove 10 shows the screws 12, but may have fire protection material between the screws 12.

Figures 3 and 4 show the structure of Figure 2 at various points along the longitudinal direction of the profiles. Figure 3 shows a fastener 16 located behind the heat shroud strip 4b on the outer edge of the pivoting profile 1, i.e., in the cavity between the heat shroud strips 4a, 4b, in the recesses formed on the outer surfaces of the profile portions 3 remaining inside the frame profile. The clamp 16 holds the profile sections 3 together at this point and is part of the locking system of the lock inserted between the profile section 3, the front plate and the fixing screw of which are also shown in the figure. Figure 4 shows the expanding material 15 in all the screw grooves 10 which open into the space 14.

Figure 5 shows another glazed building element according to the invention, which in this case is a solid structure, for example a solid wall. As with the pivoting building element, the | the structure surrounds a plate-like element, which in the following description is a glass element, but the structures can be applied to non-glazed building elements. 1 and 2. The glass elements 2 are secured to both edges of the frame profile 1, with seals 8 on opposite sides of the glass element on each side, 35 which are disposed on sealing members 7. Both sides of the frame profile have screw grooves 10 and the additional fasteners 5 described above for joining the profile portions 3 at the edge thereof and for securing the respective glass element 2. The structure of the frame profile 1 is mirror-symmetrical with respect to the plane of symmetry perpendicular to the plane of the building element. The pattern 5 may be a glass element 2 only on one side, and the opposite side kehysprofii-5 Ii structure is thus similar to the structure of the fixed profile member 1 to the image.

Figure 6 shows the joined profile sections 3 of Figure 5 without additional parts and materials. To form the frame profile 1, pro-10 profile portions 3 which have the same shape and dimensions, i.e. the same profile, can be used.

Fig. 7 is a perspective view of the structure and attachment of auxiliary fastener 5 to each profile portion 3, for clarity without a glass element 15 2. It is clear from the figure that the auxiliary fastener 5 has a plate-like blank having at each end the non-bent central portion forms the base portion 5c. Due to the location of the screw grooves 10 and the glass element 2, the projections 20 forming the engaging portion 5a are bent at the center, and the base portion 5c extends straight on both sides farther towards the ends and terminates in the other direction to the bent fastening portions 5b. The figure further illustrates how the base portion 5c may have one or more regions that have a lower heat transfer capacity across the frame profile 1 than the material of the additional fastener 5 to reduce heat transfer. In this case, the region is simply formed as an opening 20, which is easy to manufacture on the blank material. In the figure, there are two openings 20 in succession in the longitudinal direction of the frame profile 1.

Figure 7 further shows how the additional fastener 5 has a very small dimension in the longitudinal direction of the frame profile 1, thus not significantly increasing the heat transfer between the profile parts 3. Such additional fasteners may be disposed at intervals along the length of the frame profile as discrete pieces, e.g. ·. every 25-30 cm.

·, ··; 35

As mentioned above, the additional fastener 5 may also be without the glass element gripping part 5a. In this case, it has only fasteners 5b to one side of the non-bent base member 5c. Various fasteners 5 of the aforementioned types can be placed at suitable intervals along the length of the frame profile, some of which only connect the profile parts 3 together and some, in addition to the profile parts 3, also attach the glass element 2 to the frame structure.

5

The better heat resistance of the additional fastener 5 compared to the heat break structure 4 is easily accomplished by forming the additional fastener 5 from a material having a higher melting point, softening temperature or decomposition temperature than the material of the heat breaker structure 4. Thus, the elevated temperature at which the heat break loses its ability to hold the frame structure together due to melting, softening, or decomposition (e.g., burning) does not yet affect the additional fastener 5 by any of the above mechanisms so that its attachment capacity is impaired. If the heat-cut strips 4a, 4b are made of plastic, which is common due to the low thermal conductivity of the plastic, then the additional fastener 5 is preferably metal, preferably steel. A preferred additional fastener 5 material is made of stainless steel with low thermal conductivity, and especially if the glazed building element is an insulating element between the outdoor air and the interior, such as an exterior door, openable window or glazed exterior wall, its corrosion resistance is an advantage. When the additional fastener 5 is formed by bending the blank, the blank material is then a metal plate of suitable thickness, such as a steel plate, in particular a stainless steel plate.

Due to the design and the manner of attachment of the additional fastener 5, it is easy to press it into place from the outside of the profile sections 3 connected by the heat break structure 4.

In the middle chamber of the frame structure 1 inside the profile portions 3 and the heat shutters 4a, 4b, a fire-retardant filler material can be placed which extends the duration of the profile portions 3 in the fire situation, especially to prevent temperature rise. This filler material is: marked with dotted lines 22 in Figure 4. The material may be heat insulating: and, for example, release water of crystalline water, such as gypsum. If the screw grooves 10 are deep enough, the fastening portions 5b protruding from the base 35 of the auxiliary fastener 5 can be extended to surround the filler material 22 on both sides and thereby hold the filler material 22 'in place even though the hotter profile portion 3 has melted. In this case, the filler material still protects the undamaged profile part 3 on the colder side of the fire.

The filling material 22 is shown in Fig. 4 only in the central chamber, but it may also be located inside the cavities of the profile portions 3 in addition to the central chamber.

The invention is not limited to the above embodiments, but may be modified on the basis of the inventive idea set forth in the claims. Although the screws and auxiliary fasteners in connection with the vertical frame profiles of the glazed structural element frame and its surrounding fixed frame are described above, the screw and auxiliary fasteners may also be provided in other horizontal framed profiles, 3. Frame-15 profiles, in which the screws and additional fasteners described above are located, need not be exactly vertical or horizontal, but may also be inclined, depending on the structure of the building element and, in the case of fixed walls, also on architectural solutions. Likewise, the invention can be used in glazed building elements that insulate two spaces inside a building, such as swinging doors or windows between two rooms, or fixed partitions, as well as building elements that insulate the outside and inside the building, i.e., exterior doors and windows. exterior 25 walls. The figures show a glass element consisting of a single sheet of glass, but double or multiple so-called glass elements can also be used. insulating glass. A glass element is also meant to mean any element that is transparent and / or intended to give a visual impression of a glass.

30

The glass element may also be replaced by another element that insulates the two spaces and has a purpose other than to provide a visual or visual impression of the glass. Such a plate-like element may be, for example, gypsum board clad with metal paneling, which is highly resistant to heat and is particularly suitable for use in fire doors.
