Description

Profile element made of plastic and window sash and sash made of such

Profile element PP invention relates to a profile element made of plastic, in particular as a frame profile and window sash or other glazing support and for window frames or the like.

It is known from the prior art in AT 410 350 B to arrange inserts of polyurethane foam cores in some chambers of a profile element for the production of window or door frames. In view of the attainable heat transfer values, the solution described in AT 410 350 B is unsatisfactory.

Against this background, it has been proposed in DE 20 2011 003 572 U1 that the chambers of a profile element for window sashes or window frames be shuttered out with a foam material. In order to comply with passive house requirements, all chambers of the profile element are at least substantially completely foamed with a polyurethane foam according to the teaching known from DE 20 2011 003 572 U1.

In strong sunlight, however, there may be a significant heating of the respective Auftenfassade forming profile sections of the sash or window frame. This applies in particular to the case that the profile elements forming the respective window frame or the respective window sash have a dark color and thus can only reflect a small proportion of the solar radiation.

In a heat caused by solar heating the Auftenfassadenabschnitte the profile elements, the heat introduced by heat radiation in the profile element heat is forwarded by heat conduction to the insulation material. In particular, with a long-lasting solar radiation, despite the arrangement of insulating foam in the chambers of the pro-filelementes a warming of the inner facade sections of the sash or window frame done, so it may cause a Beeinrachtigung the thermal insulation of the respective window frame or sash.

Against this background, the present invention has the object to provide a profile element made of plastic, in which the insulating properties is improved with strong and especially long-lasting solar radiation. Furthermore, a corresponding window sash - hereinafter also referred to as casement - and a window frame and a combination of these are given as a complete window system.

Erfindungsgerr ^ this object is achieved with respect to the profile element with the features of claim 1. With regard to a window sash, a window frame and a combination of window sash and window frame, the stated object is achieved with the features of claims 17, 21 and 24, respectively. Preferred embodiments of the invention are set forth in the respective subclaims and are explained below.

A profiled element according to the invention has at least one prechamber and at least one inner chamber, wherein the prechamber has a chamber wall which at least partially forms an external facade wall of the profiled element and wherein the inner chamber is formed by internal chamber walls.

In the case of an external facade wall, this is a wall section which, in the installed state of the profile element, faces the outside environment and accordingly can be exposed to solar radiation. By contrast, internal chamber walls are those which are arranged between the outer facade wall of the profile element and its inner facade wall and which enclose the inner facade wall. In this context, a wall section of the profile element is to be understood as being an interior facade wall which, in the built-in state, faces the respective room of the device or of the building which is to be separated from the outside environment by the respective window. Consequently, an inner chamber in the installed state of the profile element is delimited by at least one antechamber from the outside environment.

Erfindungsgerr ^ is now provided that the at least one antechamber is filled with a ίΙίββίάΜ gene medium. If there is a strong heating of the external facade sections of the profile element due to solar radiation, the heat energy which is thereby introduced into the profile is first transferred to the ίΙίββίάΙβ β medium present in the prechamber. By heating the ίΙίββίάΙ ^ βη medium in turn its movement or flow is favored, so that a removal of the introduced heat energy is made possible. At the same time, the flow of the ίΙίββίβΙ ^ βη medium ensures convection cooling of the inner chamber wall opposite the outer facade wall. Overall, this can reduce the influence of heat conduction in the event of strong solar radiation.

Gerr ^ an advantageous embodiment of the invention, a plurality of pre-chambers and / or a plurality of inner chambers is provided. By increasing the number of chambers within the profile, both its stability and its insulating properties can be improved. A particularly good heat insulation in the case of strong sunlight can hereby be ensured by the fact that all the antechambers are filled with a flowable medium.

Preferably, at least one of the prechambers can be filled with ambient air, which can be accomplished with little effort. At the same time, it may be advantageous for the at least one pre-chamber to be substantially free of insulating materials, whereby a flow of the flowable medium can be particularly favored. Preferably, all atria are free of insulating materials.

According to a particularly preferred embodiment, at least one of the pre-chambers has at least one ventilation opening. In this case, such a ventilation opening can allow communication between the inner volume of the respective prechamber and the ambient environment, so that the air heated in the respective prechamber of the profile flows out through the ventilation opening into the ambient environment and, on the other hand, cooler intake air flows into the respective prechamber of the profile element , This can ensure a particularly effective heat dissipation from the profile element.

According to a further embodiment, the profile element has at least two pre-chambers adjacent to one another which are in fluid communication with one another through at least one ventilation opening. Demgemaft this vent can be formed in particular on an inner chamber wall of the profile element. In this way, the number of vent openings that provide immediate fluid communication with the ambient environment can be minimized. In particular, there is thus the possibility of at least one of the antechambers indirectly via ventilation openings between the respective antechambers to vent and vent. Furthermore, a flow of vaporizable medium between the respective antechambers ensures a further improved heat dissipation.

Furthermore, it may be advantageous for the at least one antechamber to have at least two ventilation openings which are arranged in different, mutually adjacent or inclined, chamber walls of the prechamber. As a result, sufficient circulation of the fluidizable medium between the antechambers of the profile and ultimately also between the antechambers and the ambient environment can reliably be achieved. This applies in particular when the respective profile element extends vertically in the installed state, since heated air rises and out of the antechamber at a higher elevation in the direction of facade height direction and cooler air from the ambient environment at a ventilation opening further down in the façade height direction through the ventilation slot in the antechamber flows in.

Equally, there is the possibility that the at least one antechamber has at least two ventilation openings which are arranged spaced apart from one another along the longitudinal orientation of the profile element or at an angle to the longitudinal orientation of the profile element. In this case, the ventilation openings in a single chamber wall, for example, the Auftenfassade forming chamber wall may be arranged. Depending on the horizontal or vertical installation orientation of the profile element, it can be ensured in this case that the two ventilation openings are arranged at different façade elevation positions and, as a result, a circulation of air through the prechamber is favored, as was explained above.

Likewise, the ventilation opening may be advantageously slit-shaped. A der-like ventilation opening can be provided with little effort, in particular be introduced in the course of an extrusion process in a chamber wall of the prechamber. At the same time, a slot shape enables good circulation of air between the respective prechamber and the outside environment or two mutually adjacent prechambers. In this case, a slot-shaped ventilation opening can extend substantially along the longitudinal orientation of the profile element or at an angle to the longitudinal orientation of the profile element. In particular, for the case that the slot-shaped ventilation opening is arranged on a Auftenfassa-denabschnitt of the profile element, the first-mentioned orientation can be advantageous if the respective profile element extends vertically in the installed state. In contrast, the last-mentioned alignment of the slot-shaped ventilation opening would be preferable if the respective profile element extends horizontally in the installed state. This is, as already described above, due to the fact that heated air rises and exits from the antechamber through the ventilation opening at an area higher in the façade height direction, and cooler air from the outside environment passes through the ventilation slit in the area lower in the façade height direction Pre-chamber flows in.

But even without vents in the antechambers can be achieved by filling the antechambers with a ίΙίββίάΙ ^ βη medium advantages in terms of thermal insulation for strong and prolonged exposure to sunlight. For even a mere circulation of the medium within the individual prechambers allows the heated medium to flow past profile sections of the respective sash frame or of the respective window frame, which have a lower temperature than the heated exterior façade sections. Through these cooler profile sections, the heat supplied can also be given back to the environment.

According to a further advantageous embodiment of the profile element at least one of the in-nenkammern is foamed with a foam material. Preferably, the inner chamber is substantially completely foamed with foam material. An "essentially complete" view of a chamber is to be understood as meaning that at least 75% of the chamber's cross-sectional area is foamed. By such foaming good insulation properties of the profile element are ensured both in terms of heat and in terms of cold. Preferably, all of the inner chambers are substantially completely foamed with a foam material.

Further, at least one of the inner chambers of the profile element may be formed as an inner facade chamber, which is at least partially formed by an inner facade wall of the profile element, wherein the inner facade chamber may be foamed with a foam material. Preferably, the interior facade chamber is substantially completely foamed with foam material. In the case of a plurality of interior facade chambers, all the interior facade chambers can preferably be foamed with a foam material, whereby the insulation properties are further improved. It is also possible to perform one or more interior facade chambers free of insulation materials, such as foam material.

As foam material for foaming the inner chambers and / or the Innenfassadenkammern example polyurethane foam can be used, which has good insulation properties and good processability. To ensure high mechanical stiffness, a reinforcing element can be provided in the at least one inner chamber. In this case, the reinforcing element can be embedded in the foam material in the inner chamber, so that both good insulation properties and high mechanical rigidity are ensured. At the same time, the reinforcing element can serve as an isothermal guide element within the profile element, which can also lead to an improvement of the insulation properties. The reinforcing element may be a profile, in particular a substantially C-shaped or box-shaped profile, which can be both produced inexpensively and introduced with little effort into the respective inner chamber. Such a profile can be made of steel, fiberglass or the like to ensure the necessary mechanical rigidity.

In order to use reinforcing elements of sufficient dimensions, the chamber volume of the inner chamber in which the reinforcing element is arranged can be greater than the chamber volume of other chambers. Equally, a chamber volume of the at least one antechamber can be greater than the chamber volume of an arming-free inner chamber and / or as the chamber volume of an inner facade chamber. A correspondingly spacious design of the prechamber ensures, on the one hand, safe removal of the introduced heat energy and, moreover, prevents excessive heating of an air volume present in the respective prechamber. For the provision of a window sash, it is particularly advantageous if the inner chamber with the reinforcing element is arranged substantially in a vertical extension of the at least one glass pane. In such an arrangement, the reinforcing element can act particularly effectively as an isothermal guide element.

A erfindungsgerr ^ er window sash is equipped with a profile element described above. In the event that the pre-chamber is provided with two ventilation openings, these are preferably spaced from each other in a vertical orientation, ie spaced apart in a mounting position of the sash along the façade height direction, regardless of whether the ventilation openings formed on a Auftenfassadenwand or an inner chamber wall are. In the event that the pre-chamber of the profile element is provided with a slot-shaped ventilation opening, this may advantageously extend substantially in a vertical orientation or substantially in a horizontal orientation. The first-mentioned alignment is advantageous if the slit-shaped ventilation opening is formed on an outer facade wall and, in an installed position of the window sash, it therefore extends in the direction of the façade height. The latter orientation, however, comes into question for slot-shaped ventilation openings on inner chamber walls.

Preferably, a window sash according to the invention is provided with a glazing bead made of plastic material, which is foam-filled with foam material, in particular polyurethane foam, which contributes to a further improvement in the insulating properties of the window sash.

Equally, a window frame according to the invention is equipped with a preceding profile element. As with the window sash described above, it is also advantageous in the case of a sash with the arrangement of two vents to arrange them in a mounted position of the sash in a vertical orientation spaced from each other to promote the circulation of air, regardless of whether the vents are formed on a Auftenfassadenwand or an internal chamber wall. Likewise, in the case of slit-shaped ventilation openings, both their essentially vertical orientation and their essentially horizontal orientation can be advantageous in order to ensure a favorable circulation of air in the pre-chamber or between two adjacent pre-chambers.

A window sash described above and a window frame described above can be combined with each other according to the invention, thereby providing a window system which has favorable insulation properties with regard to strong and in particular long-lasting solar radiation.

The invention will be explained in more detail below with reference to exemplary embodiments and associated drawings. In these show:

Fig. 2 shows a combination of a window sash with a window frame according to a first embodiment of the invention in cross section.

Fig. 3 shows a combination of a sash with a window frame according to a second embodiment of the invention in cross section.

Fig. 4 shows a combination of a sash with a window frame according to a third embodiment of the invention in cross section.

Fig. 5 shows a combination of a window sash with a window frame according to a fourth embodiment of the invention in cross section.

Fig. 6 shows a combination of a window sash with a window frame according to a fifth embodiment of the invention in cross section.

Fig. 1 shows a profile frame P of a window sash 1 shown in Fig. 2. The profile frame P - a glass plate 2 and Glashalteleiste 4 are not shown in Fig. 1 - consists of a plurality of chambers 7, wherein some of the chambers 7 as an inner chamber 7a , and some are formed as antechamber 7b. Further, some of the inner chambers 7a are formed as the inner-wall chamber 7c. Preferably in the largest of the inner chambers 7a, a reinforcing element, in particular a steel profile element 9 is used. For the further description, also of the profile frame P according to FIG. 1, reference is made to the following description of FIG. 2. In Fig. 2 is a cross-sectional view of a Fensterflü-gel 1 is shown with a used therein, only schematically illustrated laminated glass pane 2, which is held on the window sash 1 via sealing profiles 3 and a glass retaining strip 4. In Fig. 2 the sash 1 is shown in connection with a window frame 5, with which the sash 1 via sealing profiles 6 in engagement or in pressure system.

The peculiarity of the profile frame P shown in Fig. 1 and the window sash 1, hereinafter also referred to as sash 1, which has a plurality of chambers 7, is that at least one of the prechambers 7b is filled with a flowable medium 16. The ίΝθβίάΙ ^ βη medium 16 may preferably be ambient air. Advantageously, the pre-chambers 7b are filled with ambient air 16 and accordingly free of insulating materials.

The pre-chambers 7b have at least one chamber wall, which forms at least in sections an outer facade wall 18 of the profile element. Such an outer facade wall 18 is heated in strong sunlight, whereby the present in the respective antechamber 7b ίΙίββίθΙ ^ β medium 16 is heated and consequently circulates within the prechamber 7b or flows through it or flows out of this. The prechambers 7b are preferably provided with ventilation openings 17, via which heated ambient air 16 can flow out of the prechambers 7b into the outside environment U and cooler ambient air from the outside environment U can flow into the prechambers 7b. Preferably, each of the prechambers 7b is equipped with at least two ventilation openings 17, so that the circulation is promoted by the rising of the air 16 heated in the respective prechamber 7b. This applies in particular when the ventilation openings 17 are arranged at different height facade positions of the outer facade wall 18.

As further shown in Fig. 2, all the inner chambers 7a and 7c are filled or foamed with a polyurethane foam 8 as a foam material, where in the polyurethane foam 8, the inner chambers 7a and 7c of the casement 1 foams directly and directly. Preferably, however, the inner chambers 7a and 7c filled at least in a number of about 75% with polyurethane foam. Furthermore, each of the foam-filled inner chambers 7a and 7c is at least over 75%, preferably over up to 100% of its cross-sectional area and thus completely foamed.

Another peculiarity of the casement 1 is that in the largest of the inner chambers 7a an open steel profile 9 is as Profilverstarkungselement for the sash 1, which is completely foamed into the polyurethane foam 8 and, where appropriate, on edge projections 14 of the chamber wall of the respective inner chamber 7a supported.

The Stahlarmierungsprofil 9 serves the static stiffening of the sash 1, at the same time as a burglary protection and also acts as an isothermal guide element within the sash 1 in conjunction with the composite disk 2, as measurements and simulation results have shown. With regard to the effect of the Stahlarmierungsprofils 9 as Isothermenführungselement reference is made to the description in DE 20 2011 003 572 1) 1 and the accompanying figures.

In FIG. 2, the window frame 5 is also shown in cross-section, which has in a corresponding manner a plurality of chambers 11, some of which are formed as an inner chamber 11a and some as antechamber 11b. Some of the inner chambers 11a are also formed as an inner facade chamber 11c. Also in the case of the window frame 5, the pre-chambers 11b are filled with a ίϋββίείΙ '^ βη medium 16, in particular ambient air, which can flow out through vents 19 introduced into the external facade wall 20. At the same time, ambient air from the outside environment U can flow into the prechambers 11b through the ventilation openings 19.

The inner chambers 11a and 11c are preferably all, but at least in a number of 75% foamed with foam material, in particular polyurethane foam 8. Again, each of the foam inner chambers 11a and 11c at least over 75%, preferably over up to 100% of its cross-sectional area and thus completely foamed. Likewise, here too in the largest of the inner chambers 11a, substantially in vertical Ver-elongation of the composite disc 2 and the reinforced inner chamber 7a of the sash 1, a reinforcing element 12, preferably a hollow profile part made of steel, which is also completely embedded in foam material 8, in particular polyurethane foam is. Also with respect to the window frame 5 is achieved by the combination of the foam material 8 with the reinforcing profile 12 made of steel, a particularly advantageous Warmedammcharakteristik the window frame 5, on the other hand excellent mechanical stability and protection against burglary or the like. Likewise, the reinforcing profile 12 can serve as an isothermal guide element. Furthermore, the steel profile part 12 may optionally also be supported on projections 14 here.

The inner chambers 7a and 7c of the sash 1 and the inner chambers 11a and 11c of the window frame 5 are preferably foamed in situ with polyurethane, preferably using a polyurethane foam having a density of 30 to 40 kg / m3.

Such a foam with a λ-value of about 0.021 to 0.031 allows the fulfillment of the passive house normative or the requirements for low-energy house with a total

Heat transfer coefficients Uw <0.8, wherein Uw the heat transfer coefficient of the entire window, βίηεοΙηΝββοοι casement 1, window glass 2 and window frame 5, be-draws. Furthermore, the use of polyurethane foam 8 and the reinforcing profiles 9 and 12 on the one hand lightweight, on the other hand mechanically high-strength window and / or frame profile for window or door frame or the like created, so that a less dense polyurethane foam with a particularly high heat transfer resistance can be used can.

At the same time, the execution of the prechambers 7b and 11b allows a medium 16 to move in it, in particular to flow, so that during high solar irradiation and heating of the external facade wall 18 and 20 of the prechambers 7b and 11b, a heat dissipation due to flow is ensured and thus the influence of heat conduction can be reduced.

In this way, a window system consisting of window frame 5 and window sash 1 is created, in which by providing a liquid medium 16 in the prechambers 7b and 11b of the profile elements P a reduction in the influence of solar radiation, in particular in the case of darker coloring of the respective profile elements P , can be accomplished. In addition, by the use of a reinforcing element 9, 12 on the one hand and the foaming of the inner chambers 7a, 7c and 11a, 11c of the profile elements P with polyurethane foam 8 verhaltnisrr ^ig low density on the other hand passivhaustaugliche war meisolationseigenschaften be ensured.

Another advantage in this context is to use for the glazing beads 4 foamed with polyurethane foam plastic hollow profile strips. Furthermore come as reinforcing profile elements 9, 12 and profile rails made of fiber-reinforced plastics or fiber reinforced molding compounds into consideration.

In the embodiment shown in FIG. 2, as already explained above, all the inner chambers 7a, 7c and 11a, 11c are foamed with a polyurethane foam 8 and the reinforcing elements 9 and 12 are made of steel. When using a polyurethane foam having a λ value of about 0.028, a Uf value of 0.927 W / m2K is achieved, where Uf denotes the heat transfer coefficient of the frame system consisting of wing frame 1 and window frame 5.

Also in the embodiment shown in Fig. 3, some of the inner chambers 7a and 11a are foamed with a polyurethane foam 8, whereas in the window sash 1 and window frame 5 two inner facade chambers 7c and 11c are made free of polyurethane foam or other insulating materials. Likewise, the reinforcing profiles used 9 and 12 are made of steel. When using a polyurethane foam 8 with a λ value of 0.028 in the inner chambers 7a and 11a, respectively, a Uf value of 0.949 W / m2K is achieved.

In the embodiment illustrated in FIG. 4, all the interior chambers 7a, 7c and 11a, 11c are again foamed with polyurethane foam 8 having a λ value of 0.028. By contrast, the reinforcing profiles 9 and 12 are made of glasfaserverstarktem plastic and the reinforcing profile 12 of the window frame 5 is designed as a closed hollow profile. Here, an Uf value of 0.758 W / m2K is achieved.

In Fig. 5, an embodiment is schläftlich shown, in the window sash 1 a reinforcing profile 9 made of glasfaserverstarktem plastic and in the window frame 5 a reinforcing profile 12 made of steel is used. Again, the reinforcing profile 12 of the window frame 5 is designed as a closed hollow profile. Velvet interior chambers 7a and 11a and interior facade chambers 7c and 11c are foamed with a polyurethane foam 8 having a λ value of 0.028. Here, an Uf value of 0.815 W / m2K is achieved.

In Fig. 6, a fifth embodiment is shown. Unlike the embodiments in Figs. 1 to 5, gerr ^ the embodiment shown in Fig. 6, the ventilation openings 17 and 19 are formed on inner chamber walls, whereas the Außenβaden the profile elements have no ventilation openings. Accordingly, fluid communication between respectively adjacent pre-chambers 7b and 11b is ensured by the ventilation openings 17 and 19. At least one of the ventilation openings 17 and 19 ensures at least a fluid communication with the outside environment.

Of course, the invention can also be applied to door elements or other profile elements to be used or inserted in exterior walls of buildings, for example in the prefabricated house sector.
