Description

The invention relates to a profiled element made of plastic, in particular as a frame profile and as a window flap or a window flap. The invention relates to a plastic profile element, in particular as a frame profile and as a window flap or to a window flap. other glazing supports, as well as for window frames or the like. According to the state of the art it is known from document AT 410 350 B to arrange in a few chambers of a profiled element intended for the manufacture of window frames or doors, inserts made of foam cores. polyurethane. The solution described in document AT 410 350 B is unsatisfactory as to the heat transfer coefficients that can be obtained. In view of this background, it has been proposed to fill the chambers with a profile element for window wings or window frames with a foam material. To meet the requirements imposed by passive houses, DE 20 2011 003 572 U1 teaches filling all the chambers of the shaped element, at least essentially completely, with a polyurethane foam. In case of severe sunshine, however, there may be considerable heating of the profile sections forming the respective outer facade of the window sash or window frame. This applies in particular in the case where the profiled elements constituting the window frame or the window casement respectively considered have a dark color and can therefore reflect only a small fraction of the solar radiation. In the case of a high temperature rise of the outer facade sections of the profiled elements due to the insolation, heat conveyed in the profiled element by thermal radiation is transferred to the insulating material by thermal conduction. In particular, in the case of insolation of greater duration, it is possible, despite the arrangement of insulating foam in the chambers of the profiled element, to produce a heating of the inner facade sections of the window sash or window frame which may be detrimental to the thermal insulation of the window frame or frame of the respective leaf. From this background, the object of the present invention is to provide a profiled element of plastic material for which the insulating properties are improved in the case of strong insolation and in particular in the case of insolation of significant duration. In addition, there will also be provided a corresponding window flap, also referred to as a flapper frame in the following, and a window frame, and a combination thereof as a complete window system. According to the invention, this object is achieved by means of a profiled plastic element, in particular for window wings or other glazing supports or window frames, comprising at least one prechamber and having at least one minus one inner chamber, the antechamber having a chamber wall which forms, at least in sections, an outer front wall of the profiled element, and the inner chamber being formed by inner chamber walls, characterized in that said at least one prechamber is filled with a flowing fluid. As regards the purpose of a window leaf, a window frame, and a combination formed by a window leaf and a window frame, these each comprise at least one shaped member according to the invention. . A profiled element according to the invention has at least one prechamber and at least one inner chamber, the antechamber having a chamber wall which forms, at least in sections, an outer front wall of the profiled element, and the inner chamber being formed by chamber walls located therein.

In the case of an outer facade wall, this is a wall section which, in the implanted position of the profiled element, is directed towards the external environment and can therefore be exposed to solar radiation. . On the other hand, with regard to internal chamber walls, these are walls which are arranged between the outer facade wall of the profiled element and its inner facade wall, including this facade wall. interior. The designation inner wall face relates to a wall section of the profiled element which, in the implanted state, is directed to the premises of the installation or building which is to be separated from the external environment by the respective window. . Consequently, an inner chamber is delimited with respect to the external environment, in the implanted state of the profiled element, by at least one prechamber. According to the invention, it is therefore provided that said at least one prechamber is filled with a fluid capable of flowing. If, due to strong sunshine, the outer wall sections of the profiled element are subjected to a particularly high temperature rise, the heat energy thus introduced into the profile is first transmitted to the fluid that may flow. lying in the antechamber. The heating of the flowing fluid promotes, for its part, the setting in motion namely the flow thereof, which makes possible an evacuation of the heat energy that has been captured. At the same time, the flow of the flowable fluid provides convective cooling of the inner chamber wall opposite to the outer face wall. Overall, it is thus possible to reduce the influence of thermal conduction in the case of strong insolation.

According to an advantageous configuration of the invention, it is possible to provide several prechambers and / or several inner chambers. Thanks to a larger number of chambers inside the profile, it is possible to improve both its rigidity and its insulation properties. It is possible to provide a particularly effective thermal insulation in the case of strong insolation, when all of the prechambers are filled with a flowing fluid. At least one of the prechambers may preferably be filled with surrounding air, which can be achieved with very little implementation. At the same time, it may be advantageous for said at least one antechamber to be substantially free of insulating materials, thereby promoting the flow of the flowing fluid. Preferably, all prechambers are made so as to be free of insulating materials. According to a particularly preferred embodiment, at least one of the prechambers has at least one ventilation opening. Such a ventilation opening can here allow communication between the interior volume of the pre-chamber respectively considered and the external environment, so that in the pre-chamber respectively considered of the profile, highly heated air flows out of it in the outside environment, while cooler outside air flows inward from the pre-chamber respectively considered of the profiled element. This can ensure a particularly efficient evacuation of the heat towards the outside of the profiled element. According to another configuration, the profiled element has at least two mutually neighboring prechambers which are in mutual fluid communication via at least one ventilation opening. Consequently, this ventilation opening can be formed in particular on a chamber wall located inside the profiled element. In this way, the number of ventilation openings, which provide direct fluid communication with the external environment, can be limited to a minimum. In particular, it is possible to ventilate and purge at least one of the prechambers, indirectly via ventilation openings between the prechambers respectively considered. Moreover, a flow of fluid that may flow between the prechambers respectively considered, further guarantees a better heat dissipation.

Furthermore, it may be advantageous for said at least one prechamber to have at least two ventilation openings which are arranged in chamber walls of the antechamber, which extend in a manner that is close to or inclined relative to one another. This makes it possible reliably to ensure a sufficient circulation of the flowing fluid between the pre-chambers of the profile and, finally, also between the prechambers and the external environment. This is particularly the case when the profiled element respectively considered extends vertically in the implanted state because heated air tends to rise and escapes from the prechamber outwards through a ventilation opening. located in a higher position in the height direction of the facade, and colder air from the outside environment flows into the prechamber through the ventilation slot at a ventilation opening located lower in the direction of height of the facade.

Similarly, it is possible that said at least one prechamber has at least two ventilation openings which are arranged spaced apart along the longitudinal orientation of the profiled element or at an angle to the orientation. longitudinal section of the profiled element. The ventilation openings can here be arranged in a single chamber wall, for example the chamber wall forming the outer facade. According to the horizontal or vertical implantation orientation of the profiled element, it is possible here to guarantee that the two ventilation openings are arranged at different positions of façade height, thereby promoting air circulation through the wall. prechamber, as mentioned above.

The ventilation opening can also be advantageously made in the form of a slot. Such a ventilation opening can be obtained by a reduced implementation, in particular be carried out in a chamber wall of the antechamber, during an extrusion process. A slot shape also allows good air circulation between the prechamber respectively considered and the external environment, or between two prechamber mutually neighboring. A slot-shaped ventilation opening here can extend essentially along the longitudinal orientation of the profiled element or at an angle to the longitudinal orientation of the profiled element. Particularly in the case where the slot-shaped ventilation opening is arranged on an outer face section of the profiled element, the orientation mentioned first may be advantageous when the profiled element respectively considered extends vertically. in the implanted state. On the other hand, the last-mentioned orientation of the slot-shaped ventilation opening will be preferred when the profiled member respectively extends horizontally in the implanted state. This results from the fact that, as already described before, heated air rises and escapes from the prechamber through the ventilation opening, in a zone situated higher with reference to the direction of height of the facade, and the colder air from the outside environment flows into the prechamber through the ventilation slot located at a lower point with reference to the height direction of the facade. But even without ventilation openings in the prechambers, it is possible to obtain, thanks to a filling prechambers with a flowing fluid, advantages concerning the thermal insulation in the case of a high-intensity insolation and persistent for a longer period. Indeed, already only a circulation of the fluid inside the individual prechambers allows the heated fluid to flow along profiled sections of respectively considered frame or window frame respectively which have a lower temperature than the exterior facade sections that have undergone significant heating. Thanks to these sections of colder sections, the heat supplied can be evacuated to the environment again. According to another advantageous configuration of the profiled element, said at least one inner chamber is filled with a foam material. The inner chamber is preferably filled substantially entirely with a foam material. The "essentially total filling" of a chamber foam refers to the fact that at least 75% of the cross-sectional area of a chamber is filled with foam. Thanks to such a foam filling, good insulation properties of the profiled element are guaranteed, both as regards the heat and the cold. Preferably, all the inner chambers are filled essentially entirely with a foam material.

Furthermore, at least one of the inner chambers of the profiled element can be formed as an inner facade chamber which is at least formed in sections by an inner front wall of the profiled element, the inner facade chamber can also be filled with a foam material. The inner facade chamber is preferably substantially completely filled with a foam material. In the case of several interior facing chambers, it is possible to preferably fill all the interior facing chambers with a foam material, which further improves the insulation properties. It is also possible to make one or more interior facing chambers free of insulating materials such as foam material. As a foam material for the foam filling of the interior chambers and / or inner facade chambers, it is for example possible to use a polyurethane foam which has good insulating properties and a good ability to artwork.

In order to guarantee high mechanical rigidities, it is possible to provide a reinforcing reinforcement element in said at least one inner chamber. This reinforcing reinforcement element can here be embedded in the foam material inside the inner chamber, so that good insulating properties as well as high mechanical rigidity are thus guaranteed. At the same time, the reinforcing reinforcement element can serve as an isothermal conduction element within the profiled element, which can also lead to an improvement of the insulating properties. The reinforcing reinforcement element may be a profile, in particular a C-shaped profile or a box profile which is of a favorable fabrication and may be introduced into the inner chamber respectively considered, requiring only one weak implementation. Such a profile can be made of steel, plastic reinforced with glass fibers or a similar material, to ensure the necessary mechanical rigidity. In order to be able to use reinforcing reinforcement elements of sufficient dimensions, the chamber volume of the inner chamber, in which the reinforcing reinforcement element is arranged, may be larger than the chamber volume of other chambers. . Likewise, a chamber volume of said at least one prechamber may be larger than the chamber volume of an interior chamber free of reinforcing reinforcement and / or the chamber volume of an interior facade chamber. A suitable wide configuration of the prechamber guarantees on the one hand a reliable discharge of the heat energy introduced, and furthermore prevents a high temperature rise of a volume of air present in the pre-chamber respectively considered. The profiled element may preferably be connected to at least one, preferably several, glass panes. For the production of a window leaf, it is particularly advantageous for the inner chamber comprising the reinforcing armature element to be arranged essentially in a vertical extension of the at least one glass pane. In the case of such an arrangement, the reinforcing armature element can function particularly effectively as an isothermal conduction element. A window leaf according to the invention is equipped with a profiled element previously described. In the case where the prechamber has at least two ventilation apertures, these are preferably arranged spaced apart in the direction of the vertical orientation, and are accordingly mutually spaced along the height direction of the facade. , in the implantation position, regardless of whether the ventilation openings are made on an outer wall face or a chamber wall located inside. In the case where the prechamber is provided with a slot-shaped ventilation opening, it can advantageously extend substantially in a vertical orientation or in a substantially horizontal orientation. The first mentioned orientation is advantageous when the slot-shaped ventilation opening is made on an outer facade wall, and that, in an implanted position of the window sill, it extends accordingly in the direction of height of the facade. On the other hand, the last-mentioned orientation is taken into consideration for slot-shaped ventilation openings on interior chamber walls.

A window leaf according to the invention is preferably equipped with a glass glazing bead, made of a plastic material which is filled with a foam material, in particular a polyurethane foam, which contributes to further improving the Insulating properties of the window flap.

Similarly, a window frame according to the invention is equipped with a profiled element previously mentioned. As has been described with regard to the window leaf, it is also advantageous for a window frame, in the case of the arrangement of two ventilation openings, to arrange them, for an implanted position of the window. window frame, mutually spaced in the direction of the vertical orientation, with a view to promoting the circulation of air, regardless of whether the ventilation apertures are made on an outer facade wall or on a chamber wall situated inside. Similarly, in the case of ventilation openings of a slot-like configuration, both a substantially vertical orientation and a substantially horizontal orientation may be advantageous for promoting air circulation in the prechamber or between two prechambers. A previously described window flap and window frame may, in accordance with the invention, be combined with one another to thereby form a window system which has favorable insulation properties also in the case of a window frame. strong sunstroke, especially persistent insolation for a longer period of time. The invention will be explained in more detail hereinafter with reference to exemplary embodiments and the accompanying drawings which show: FIG. 1 a profiled element of a window leaf according to an exemplary embodiment of the invention, in cross section. Fig. 2 a combination of a window leaf with a window frame, according to a first embodiment of the invention, in cross section. Fig. 3 a combination of a window leaf with a window frame, according to a second embodiment of the invention, in cross-section. Fig. 4 a combination of a window leaf with a window frame, according to a third embodiment of the invention, in cross section. Fig. A combination of a window sash with a window frame, according to a fourth embodiment of the invention, in cross-section. Fig. 6 a combination of a window leaf with a window frame, according to a fifth embodiment of the invention, in cross section. FIG. 1 shows a profiled element P of a window leaf 1 shown in FIG. 2. The profiled element P - a glass pane 2 and a glass pane 4 are not shown in FIG. consists of a plurality of chambers 7, some of the chambers 7 being made as an inner chamber 7a and some as prechamber 7b. On the other hand, some of the inner chambers 7a are made as inner facade chambers 7c. Preferably in the larger of the inner chambers 7a there is inserted a reinforcing reinforcement member, in particular a steel profile member 9. For the rest of the description, also of the profiled element P according to FIG. 1, reference will be made to the description of FIG. 2 which will follow. FIG. 2 shows a cross-sectional representation of a window flap 1 in which a laminated glass pane 2 has been placed, which is only shown diagrammatically and is held on the window flap 1 by the window flap 1. 3. In FIG. 2, the window leaf 1 is shown in combination with a window frame 5, with which the window leaf 1 is in contact, that is pressurized by means of sealing profiles 6. The particularity of the profiled element P shown in FIG. 1, namely of the window flap 1, also designated by the flapper frame 1 in the following, which has several chambers 7, resides in the fact that at least one of prechambers 7b is filled with a fluid 16 flowing. As regards the flowable fluid 16, it may be preferably ambient air. Advantageously, the prechambers 7b are exclusively filled with surrounding air 16, and therefore free of insulating materials.

Prechambers 7b have at least one chamber wall which forms, at least in sections, an outer front wall 18 of the profiled element. Such an outer face wall 18 undergoes a strong heating in the case of a strong insolation, which leads to the heating of the flowing fluid 16 present in the prechamber 7b respectively considered, which consequently flows to the inside the prechamber 7b or flows inside it or out of it. Prechambers 7b are preferably provided with ventilation openings 17 by means of which the heated ambient air 16 can flow out of prechambers 7b into the outside environment U, and from the colder surrounding air of the Outside environment U can flow inward of prechambers 7b. Each prechambers 7b is provided with at least two ventilation openings 17, so that the circulation is favored by the rise of the air 16 heated in the prechamber 7b respectively considered. This is particularly true when the ventilation openings 17 are arranged at different facade height positions of the outer facade wall 18.

As is also shown in FIG. 2, all the inner chambers 7a and 7c are filled, namely filled with polyurethane foam 8 as a foam material, the polyurethane foam 8 filling the inner chambers 7a and 7c. of the casement frame 1, directly without other auxiliary means. The inner chambers 7a and 7c, however, are preferably filled to a number of about 75% with polyurethane foam. Furthermore, each of the inner chambers 7a and 7c filled with foam, is filled at least 75%, preferably up to 100%, of its cross-sectional area, and therefore in full. Another particularity of the casement frame 1 lies in the fact that in the largest of the inner chambers 7a, there is an open steel section 9, as a profile reinforcing element for the casement frame 1, and which is completely embedded in the polyurethane foam 8 and is supported, where appropriate, on edge protuberances 14 of the chamber wall of the inner chamber 7a respectively considered. The reinforcement reinforcement profile 9, made of steel, serves for the static stiffening of the flapper frame 1, and at the same time also for intruder protection, and also acts as an isothermal conduction element for the inside of the flapper frame 1 in combination with the laminated glazing 2, as shown by measurements and simulation tests. With regard to the action of the reinforcement reinforcing section 9 made of steel, as an isothermal conduction element, reference may be made to the description of the document DE 201003 572 Ul, as well as to the corresponding figures.

Figure 2 is simultaneously shown, in cross section, the window frame 5 which correspondingly has a plurality of chambers 11, some of which are formed as inner chamber 11a and some as prechamber 11b. Some of the inner chambers 11a are additionally provided as inner facade chamber 11c. In the case of the window frame 5, the prechambers 11b are also filled with a flowing fluid 16, in particular surrounding air which can flow outwards through the ventilation apertures 19. 20. Simultaneously, surrounding air from the outside environment U can flow inside the prechambers 11b, through the ventilation openings 19.

The inner chambers 11a and 11c are preferably all, but at least 75% of the total, filled with a foam material, in particular polyurethane foam 8. Here again, each of the inner chambers 11a and 11c filled with foam, is filled over at least 75%, preferably up to 100% of its cross-sectional area, and therefore in full. Here also, in the largest of the inner chambers 11a, essentially in vertical extension of the laminated glazing 2 as well as the inner chamber 7a reinforced with the window flap 1, there is a reinforcing reinforcing element 12, preferably a piece of hollow steel profile which is also completely embedded in foam material 8, in particular polyurethane foam. With regard to the window frame 5, the combination of the foam material 8 with the reinforcement reinforcing section 12 made of steel also makes it possible to obtain an advantageous thermal insulation characteristic of the window frame 5, and of on the other hand, exceptional mechanical stability and protection against intrusion or the like. The reinforcing reinforcement section 12 can likewise act as an isothermal conduction element. Furthermore, the steel profile piece 12 can here also be supported on any protuberances 14.

The inner chambers 7a and 7c of the flapper frame 1 and the inner chambers 11a and 11c of the window frame 5 are preferably filled in situ with polyurethane foam, and preferably a polyurethane foam is used. a density of 30 to 40 kg / m3.

Such a foam with a coefficient X of approximately 0.021 to 0.031 generally makes it possible to meet passive house standards or low-energy home requirements, with a thermal transmission coefficient Uvv <0.8, where Uw denotes the heat transfer coefficient of the whole of the window, including the casement frame 1, the window glazing 2 and the window frame 5. Moreover, thanks to the use of polyurethane foam 8, as well as reinforcement reinforcement profiles 9 and 12, there is provided a window and / or frame profile for window or door frames or the like, on the one hand light and on the other hand of great mechanical strength, so that it is possible to use a lower density polyurethane foam with a particularly high thermal resistance.

At the same time, the configuration of prechambers 7b and 11b makes it possible to ensure that in these movements, in particular flows a fluid 16 that can flow, so that in the case of a strong insolation, as well as a significant heating of the outer facade wall 18 and 20 prechambers 7b and 11b that results, it is possible to ensure a flow of heat evacuation, thereby reducing the influence of thermal conduction . In this way, a window system consisting of a window frame 5 and a window leaf 1 is produced, in which, thanks to the presence of a fluid 16 that can flow, in the precombings 7b and In the case of profile elements P, it is possible to reduce the influence of insolation, in particular in the case of a dark coloring of the profile elements P respectively considered. In addition, thanks to the use of a reinforcing reinforcement element 9, 12 on the one hand, and the foam filling of the inner chambers 7a, 7c and 11a, 11c of the profile elements P with foam of polyurethane 8 of relatively low density on the other hand, it is possible to ensure thermal insulation properties suitable for passive houses.

Another advantage in this respect also consists in using, for the glazing fixing beads 4, hollow profile strips of plastic material filled with polyurethane foam. On the other hand, profile rails made of fiber-reinforced plastics or fiber-reinforced compressed substances are also used as reinforcing reinforcement profile elements 9, 2. In the case of the embodiment shown in FIG. 2, all of the inner chambers 7a, 7c and 11a, 11c are, as already mentioned above, filled with a polyurethane foam 8 and the reinforcing elements of reinforcement 9 and 12 are made of steel. In the case of using a polyurethane foam with a coefficient I of about 0.028, a Uf coefficient of 0.927 Wirin2K is obtained here, Uf denoting the thermal conductivity coefficient of the frame system consisting of the flapper frame 1 and window frame 5.

In the embodiment shown in Figure 3, some of the inner chambers 7a and 11a are also filled with a polyurethane foam 8, while respectively in the window sash 1 and in the window frame 5, two chambers 7c and 11c interior facade are made free of polyurethane foam or other insulating materials. The reinforcement reinforcement profiles 9 and 12 used are also made of steel. In the case of using a polyurethane foam 8 with an X coefficient of 0.028 in the respective inner chambers 7a and 11a, a Uf coefficient of 0.949 W / m2K is obtained.

In the embodiment shown in Figure 4, all inner chambers 7a, 7c and 11a, 11c are again filled with a polyurethane foam 8 with a coefficient X of 0.028. On the other hand, the reinforcement reinforcement sections 9 and 12 are made of a glass fiber reinforced plastic material, and the reinforcement reinforcement profile 12 of the window frame 5 is made in the form of a closed hollow section. In this case, a Uf coefficient of 0.758 W / m2K is obtained. Figure 5 is finally shown an embodiment according to which in the window leaf 1 is inserted a reinforcement reinforcement section 9 made of plastic material reinforced with glass fibers, and in the window frame 5, a profile of reinforcement frame 12 made of steel. The reinforcing reinforcement profile 12 of the window frame 5 is here also produced in the form of a closed hollow section. All the inner chambers 7a and 11a and the inner front chambers 7c and 11c respectively are filled with a polyurethane foam 8 with an X coefficient of 0.028. In this case, a Uf coefficient of 0.815 W / m2K is obtained. In Figure 6 is shown a fifth embodiment. In contrast to the embodiments of FIGS. 1 to 5, the ventilation apertures 17 and 19 are formed, in the case of the embodiment shown in FIG. 6, in chamber walls situated inside, while the external wall faces of the profile elements do not have ventilation openings. Accordingly, the ventilation openings 17 and 19 according to Figure 6 provide fluid communication between prbmbers 7b and 11b respectively adjacent. At least one of the ventilation openings 17 and 19 here ultimately provides a fluid communication with the external environment.

The invention can of course also be implemented for door elements or other profile elements to be placed or placed in building walls, for example in the field of prefabricated houses.
