Description

PROFILE ELEMENT OF ARTIFICIAL AND WINDOWS AND WINDOWS CONSISTING OF SUCH FRQ FILE ELEMENT

The invention relates to a profile element made of plastic, icing as frame profile and window wing or other window carriers, as well as to window frames or the like.

From the state of the art, it is known in AT 410 350 B to place inserts of polyurethane foam cores in some chambers of a profile element for the manufacture of window or door frames. For the attainable heat transfer values, the solution described in AT 410 350 B is not satisfactory. Against this background, it is proposed in DE 20 2011 003 572 U1 to foam the chambers of a profile element for window joints or window frames with a foam material. In order to meet passport requirements, according to the known from DE 20 2011 003 572 U1, all chambers of the profile element are at least substantially completely filled with a polyufethane foam.

By GB 2 488 670 A, it is well known to design a profile element in plastic, especially ten! window wing (1) or other window carriers or window frames (5), comprising a front chamber (7b 11b 11c) and a spring chamber (7a, 13), wherein the front chamber (7b, 11b, 11c) is provided with a chamber wall at least sectionally forming an outer face wall of the profile element (P) and wherein the inner chamber (7a, 13) is formed by internally located chamber walls and at least one anterior chamber (7b; 11b, 11c) is filled with a gaseous medium.

However, this profile element suffers from a weak or lack of heat transport out of the profile body, especially in the case of strong sunlight where a significant heating of the profile section of the window or window frame forming the relevant exterior facade may occur. This is especially true in that case; where the profile elements that form the respective window frame or the respective viridue wing are ten a dark color and thus can only reflect a small proportion of the solar radiation.

As a result of the solar incident heating of the outer surface sections of the profile elements, heat which is introduced into the profile element by heat pendant is passed on to the insulating material. Especially in the case of prolonged solar incidence, in spite of the insertion of foam insulation in the chambers of the profile element, heating of the inner facade section of the window or window frame can occur, so that an effect on the thermal insulation of the respective window frame or window wing can occur. In view of the foregoing, it is the first object of the present invention to provide a plastic profile element in which the isofering properties are enhanced by strong and especially prolonged solar incidence. Furthermore, a corresponding window wing must be specified - subsequently also referred to as wing frame - and a window frame as well as a combination of these as a complete window system; In accordance with the invention, this purpose with respect to the profile element is fulfilled with the features of claim 1. With respect to ten! a window wing, a window frame, and a combination of window wing and window frame, the said purpose is met with the features of claims 11, 13 and 14. Preferred embodiments of the invention are set forth in the respective subclaims and are explained below.

A profile element according to the invention has at least one anterior chamber and at least one inner chamber, the anterior chamber having a chamber wall forming at least sectionally an outer facade wall of the profile element and the inner chamber being formed by internally located chamber walls.

In this connection, an external facade wall is a wall section which, in the built-in condition of the profile, is facing the external environment and may consequently be exposed to sunlight. Opposite to this, the interior walls of the chamber are those which are arranged between the outer facade wall of the profile element as well as the divided inner facade wall, the inner facade wall included. In this connection, an internal facade wall is understood to mean a wall section of the prole element, which is in built-in condition facing the respective space of the device and the building, respectively, to be separated from the external environment by means of the window in question. the built-in condition of the profile element delimited from the external environment by at least one anterior chamber.

According to the invention, it is proposed that at least one chamber is filled with a gaseous medium, preferably ambient air. Should a strong heating of the outer façade section of the profile element occur, due to the solar incident, the thermal energy introduced in the profile is first transferred to the gaseous medium in the anterior chamber. As a result of the heating of the gaseous medium, movement or flow are favored again, so that a transport of your introduced heat energy is mulled. At the same time, the flow of the gaseous medium ensures one convection cooling of the inner chamber wall adjacent to the pear facade wall. Overall, the influence of the heat conduction can be reduced in case of strong sunlight *

According to an advantageous embodiment of the invention, there are provided a number of anterior chambers or a plurality of inner chambers. Due to a larger number of chambers within the profile, both its stability and shared insulation properties can be improved. A particularly good heat insulation in case of strong sunlight can in this connection be ensured by the fact that all the chambers are filled with a liquid medium.

Preferably, at least one of the chambers may be filled with ambient air, which can be accomplished with only a few resources. At the same time, it may be advantageous that the at least one anterior chamber is substantially free of insulating materials, whereby a flow of the liquid medium can be favored in a particular way. Preferably, everyone is wrong !! made free of insulating materials.

According to a further embodiment, the profile element exhibits at least two adjacent chambers which are in mutual fluid communication by means of at least one ventilation opening. Accordingly, this ventilation opening may in particular be formed on an internally located chamber wall of the profile element. In this way, the number of ventilation openings which ensure immediate fluid communication with the external environment can be limited to a minimum, in particular there is thus the possibility to oxygenate and vent at least one of the chambers by means of ventilation openings between the respective chambers. Furthermore, a flow of the liquid medium between the respective chambers ensures a still improved heat dissipation.

Furthermore, it may be advantageous for the at least one chamber to have at least two ventilation openings located in different, mutually adjacent or inclined chamber walls of the chamber. In this way, a sufficient circulation of the liquid medium between the profile chambers and finally also between the chambers and the external environment can be reliably favored. This is especially true when the respective profile element extends vertically in the built-in state, as heated air rises to the weather and flows out of the chamber at a facade height direction further up the ventrifuge phase, and cooler air from the external environment flows into the chamber through the ventilation slot at a in the lower elevation of the ventilation opening: in the same way it is possible that the at least one front chamber exhibits at least two ventilation openings which are> l | ten distances apart from the profile element's longitudinal orientation or at an angle to the profile element's length orientation. In this connection, the ventilation channels may be arranged in a single chamber wall, for example the chamber wall forming the outer facade. Depending on the horizontal or vertical installation orientation of the profile element, in this connection it can be ensured that the two ventilation openings are arranged at different facade height positions, thereby favoring a circulation of air through the front chamber, as stated above.

Also, the venipilation opening may advantageously be slit-shaped. Such a ventilation opening can be provided with only a few resources, in particular it can be inserted into a chamber wall of the anterior chamber when performing an extrusion process. At the same time, a slit mold permits good circulation of air between the respective anterior chamber as well as the external environment or two adjacent chambers. In this connection, a side-shaped ventilation opening can extend substantially along the longitudinal orientation of the profiled element or at an angle to the captive de-orientation of the profiled element. In particular, in the case where the slit-shaped valve aperture opening is disposed on an outer face portion of the profile element, the first-mentioned orientation therein may be advantageous when the respective profile element extends vertically in a built-in condition. Against this, the latter orientation of the slit-shaped ventilation opening would be preferable when the respective profile element extends horizontally in the built-in Ilétand, which, as already described above, is conditioned on the fact that heated air rises and flows out of the chamber through the ventilation system. by a ventilation sieve located further up in the facade height direction, and cooler air from the external environment flows into the chamber through the ventilation slot at a ventilation point located further down the facade height direction.

However, even without ventilation openings in the chambers, by filling the chambers with a gaseous medium such as air, benefits can be obtained with regard to heat insulation in case of strong and prolonged solar incidence. Already, only the circulation of the medium within the individual chambers allows the heated medium to flow past the profile sections of the respective wing frame or window frame which have a lower temperature than the heated outer facade sections. With the help of these cool profile sections, the heat supplied can also be released to the surroundings again.

According to a further advantageous embodiment of the proil element, at least one of the inner chambers is foamed with a foam material. Preferably, the inner chamber is substantially completely foamed with foam material. In this context, a "substantially complete" foaming of a chamber is understood to mean that at least 75% of the cross-sectional area of the chamber is foamed. By means of such foaming good insulation properties of the profile element are assured both for heat and with Preferably, all of the inner chambers are substantially completely foamed with a foam material.

Furthermore, at least one of the profile elements' inner chambers may be formed as an inner facade chamber, which is formed at least in section by an inner wall of the profile element, where also the inner facade chamber can be foamed with foam material. Preferably, the inner facade chamber is substantially completely foamed with foam material. Preferably, for a number of inner façade chambers, all of the interior façade chambers may be foamed with a foam material, thereby further improving the insulation properties. Also, it is possible to perform one or more interior facade chambers free of insulating materials, such as, for example, sium material.

As foam material ten! For example, in foaming of the inner chambers and / or the inner chambers, polyurethane foam having good insulating properties and good workability can be used.

For securing high mechanical stiffnesses, a reinforcing element may be provided in at least one inner chamber. In this connection, the reinforcing element in the inner chamber may be embedded in the foam material so as to ensure both good insulation properties and a high mechanical stiffness. At the same time, the reinforcing element can serve as an isothermal control element in the profile element, which can also improve the insulation properties; The armor recorder element may be a profile, in particular a substantially C-shaped profile or box profile, which can both be manufactured in a favorable manner and can also be inserted into the respective inner chamber with only a few resources. Such a profile may 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 located may be greater than the chamber volume of other chambers. Similarly, a chamber volume of the at least one anterior chamber may be greater than the chamber volume of a reinforcement-free inner chamber and / or greater than the chamber volume of an inner facade chamber. A correspondingly spacious design of the pre-chamber, on the one hand, ensures a safe away transport of the introduced heat energy and also prevents a strong heating of a volumetric volume present in the respective pre-chamber.

For providing a window wing, it is particularly advantageous when the inlet chamber with the reinforcing element is arranged substantially in a vertical extension of the smallest glass pane. In such an arrangement, the reinforcing element can act particularly effectively as an isthermic control element.

A window according to the invention is equipped with a profile described above. in the case where the front chamber is provided with two ventilation openings, these are preferably arranged in vertical orientation at a distance from one another, ie in a built-in position for the window wing at a distance from one another along the facade height direction, regardless of whether the ventilation openings are formed on a exterior facade wall or an internally located chamber wall. In the case where the front chamber of the profile element is provided with a coil-shaped ventilation opening, it may advantageously extend substantially in vertical orientation or substantially in horizontal orientation. The former orientation is advantageous when the side-shaped ventilation opening is formed on an outer façade wall and, consequently, in a built-in position for the window wing extends in facade height. The latter orientation, on the other hand, applies to slit-shaped ventilation openings on internally located chamber walls.

Preferably, a window wing according to the invention is provided with a plastic mattress glass holder foamed with foam material, especially polyurethane foam, which contributes to a further improvement of the window wing insulation properties. In the same way, the window frame according to the invention is equipped with a profit element mentioned above. As in the case of the above-described Window Eye, it is also advantageous, in the case of a window frame by placing two ventilation openings, to place them in a built-in position for the window frame in vertical orientation t apart from each other to favor the circulation of air irrespective of whether the ventilation openings are formed on an outer facade wall or an interior chamber wall. Likewise, in a side-shaped design of ventilation openings, both their substantially vertical orientation and their substantially horizontal orientation may be advantageous in ensuring a favorable circulation of air in the anterior chamber or between two adjacent anterior chambers.

A window window described above as well as a window frame described above can be combined with one another on a mite according to the invention, thereby providing a window system which has favorable insulating properties with regard to strong and especially prolonged solar incidence.

The invention will now be explained in more detail by way of examples and accompanying drawings. In these ways FIG. 1 is a sectional view of a window wing according to a cross-sectional embodiment of the invention; FIG. 2 shows a combination of a window wing with a window frame according to a first embodiment example of the invention in cross section; FIG. 3 a combination of a window wing with a window frame according to a second embodiment example of the invention in cross section; FIG. 4 a combination of a window wing with a window frame according to the invention. a third embodiment of the invention in cross section; in a combination of a window wing with a window frame according to a fourth embodiment example p in the invention in cross section; 6 is a combination of a window wing with one window frame according to a fifth embodiment of the invention in cross section.

FIG. 1 shows a profile frame P of one of FIG. 2 window display 1. The profile frame P - a glass pane 2 and glass retaining strip 4 are not shown in fig. 1 - consists of a plurality of chambers 7, some of the chambers 7 being formed as inner chamber 7a and some as chambers 7b. Furthermore, some of the inner chambers 7a are configured as inner facade chambers 7e. One reinforcing element, in particular a steel profile element 9, is preferably inserted into the largest of the inner chambers 7a.

For further description, also of the profile frame P according to FIG. I, reference is made to the following description of FIG. 2. PI fig. 2 is a cross-sectional view of a window wing 1 with a laminated glass pane 2, shown diagrammatically shown in this insert, only held on the window wing 1 via sealing profiles 3 and a glass retaining strip 4. In FIG. 2, the window wing 1 is fan in conjunction with a window frame 5, with which the window wing 1 via sealing profiles 6 are engaged respectively in press systems. The peculiarity of the one shown in FIG. in shown profile frame P and window wing 1, respectively, subsequently also referred to as wing frame 1, which exhibits a number of chambers 7, consists in that at least one of the chambers 7b is filled with a gaseous medium 16. The gaseous medium 16 may preferably be about ambient. P | advantageously, the chambers 7b are filled exclusively with ambient air 16 and consequently free of insulating materials.

The anterior chambers 7b exhibit at least one chamber wall forming at least sectionally an outer wall 18 of the profile element. Such an outer façade wall 18 is heated at high solar incidence, whereby the liquid medium 16 present in the respective pre-chamber 7b is heated and as a result circulates within or out of the pre-chamber 7b, respectively. Preferably, the front chambers 7b are provided with ventilation openings 17, through which heated ambient air 16 can flow out of the front chambers 7b and into the external environment, and cooler ambient air can flow from the external surroundings into the front chambers 7b. Preferably, each of the front chambers 7b is provided with at least two ventilation openings 17, so that the circulation is favored by the rise in weather of the air 16 heated in the respective front chamber 7b. This is especially true when the ventilation openings 17 are arranged at different height facade positions of the outer facade funnel 18

As further vM is shown in FIG. i, all of the inner chambers 1a and 7c are filled respectively with a polyurethane foam 8, respectively. As foam material, the polyurethane foam 8 directly and directly foams the inner chambers 7a and 7c of the wing frame 1, however, preferably at least about 75 in the inner chambers 7 % filled with polyurethane foam. Furthermore, each of the foamed inner chambers 7a and 7c is foamed at least over 75%, preferably over up to 100% of their cross-sectional surface and thus complete.

A further peculiarity of the wing frame 1 consists in the fact that in most of the inner chambers 7a there is an open steel profile 9 as a profile reinforcing element for the wing frame 1, which is completely foamed in the polyurethane foam fabric 8. The steel reinforcement profile 9 serves ten! static stiffening of the fixture frame 1, as well as intrusion protection, and also acts as isothermal control element within the wingframe 1 in connection with the laminated pane which measurements and simulation results have shown. With regard to the effect of steel reinforcement profile 9 as an isothermal control element, reference is made to ten! the description in DE 20 2011 003 572 OT and the associated figures. In FIG. 2, the window frame 5 is also shown in cross-section, correspondingly showing a number of chambers 11, some of which are designed as inner chamber 11a and some as chamber 11b. In addition, some of the inner chambers 11a are designed as inner facade chambers 11c. Also at the window frame 5, the front chambers 11b are filled with a gaseous medium 16, in particular ambient air, which can flow out through ventilation ducts 19 inserted into the outer facade wall 20. At the same time, ambient end from the external surroundings U can flow into the front chambers 11h through the ventilation openings 19 .

The inner chambers 11a and 11c are preferably completely but at least 75% foamed with foam material, especially polyurethane foam 8. Here, too, each of the foamed inner chambers 11a and 11 © is at least foamed above 75%, preferably over up to 100% of their cross-sectional surface and thus completely. Likewise, also here, in the largest of the inner chambers 11a, there is substantially in the vertical extension of the laminated pane 2 and the reinforced inner chamber 7a of the frame 1, a reinforcing element 12; preferably a hollow profile part of steel which is also completely embedded in foam material 8, especially polyurethane foam. Also with respect to the window frame 5, the combination of the foam material 8 with the steel reinforcing profile 12 provides a particularly advantageous heat insulation characteristic for the window frame 1, on the other hand excellent mechanical stability and protection against break-in or the like. Similarly, the reinforcing profile 12 can serve as an isothermal control element. Furthermore, if necessary, Ide le n 12 may be supported on projections 14.

The inner chambers 7a and 7c of the wing frame 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 / rt3. One such foam having an A ^ value of about 0.021 to 0.031 allows for overall compliance with the passive house regulations and low-energy houses, respectively, with a heat transfer coefficient Uw <0.8, where Uw represents the heat-through coefficient of the total window; including wing frame 1, window glass 2 and window frame 5. Furthermore, as a result of the use of polyurethane foam 8 and the reinforcing profiles 9 and 12, a window and / or frame window profile, on the other hand, a window and / or frame profile with mechanical high strength for window or door frames or the like, so that a less dense padding glove with particularly high heat transfer resistance can be used. At the same time, the design of the front chambers 7b and 11b allows a gaseous medium IB to move, especially currents, therein, so that in the case of strong sunlight and consequent heating of the front room walls 1b and 11b 1 | and 20, a heat-transfer transport resulting from flow is ensured, and consequently a reduced influence from the heat conduction In this way, a windowing system consisting of window frame 5 and window wing 1 is created, whereby gases 7b and 11b of the profile elements P can be provided with a gaseous medium 16 a reduction of the influence of sunlight, especially in the dark colors of the respective profile elements P. Further, by using a reinforcing element 9, 12 on one side and foaming of the inner chambers 7a, 7c and 11a, 11c with polyurethane foam 8 with low density, on the other hand, ensures passive house-suitable heat insulation properties. In this connection, it is a further advantage to use polyurethane foam foamed plastic hole profiles for the glass retaining strips 4. Furthermore, profile rails of fiber-reinforced plastics or fiber-reinforced molding materials are also considered as reinforcing profile elements 9, 12.

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

Also in the case shown in FIG. 3, some of the inner chambers 7a and 11a are foamed with a polyurethane foam 8, whereas two inner-face chambers 7c and 11c in window loop 1 and window frame 5 are each made free of puddle gloves or other insulating materials. Similarly, the reinforcing profiles 9 and 12 used are made of steel. By using a polyurethane foam 8 having a λ value of 0.028 in the inner chambers 7a and 11a respectively, a Uf value of 0.949 W / m2K is obtained.

In the embodiment of FIG. 4, again, all of the inner chambers 7a, 1e, and 11a, the Heucl foam with polyurethane foam 8 having one λ value of δ, i | 8. By contrast, the reinforcement profiles 1 and 1 are made of fiberglass-reinforced plastic, and the window frame 5 reinforcement profile! 12 is made as a closed hole profile. This gives a Uf value of 0.758 W / m2K. In FIG. 5 is finally shown in an embodiment in which a reinforcing profile 9 of fiberglass reinforced plastic is inserted into the window wing 1 and in the window frame 5 a reinforcing profile 12 of steel. Here, too, the reinforcement profile 12 of the window frame 5 is made as a closed hole roll. All of the inner chambers 1a and 11a, respectively, of the internal facade chambers 1 and 1, are foamed with a polyurethane foam 8 having an λ value of 0.028. This gives a Uf value of 0.815 VWm2K. FIG. 6 is shown a fifth embodiment. Different from the embodiments of Figures 1 to 5, the ventilation openings 11 and 19 of the pi of Figs. The embodiment shown on the interior of the chamber walls, while the outer facade walls of the profile elements show no ventilation openings. Thus, by means of the ventilation openings 17 and 19 according to # fig. A gaseous communication between in each case adjacent chambers 7b and 11b. In this connection, at least one of the ventilation openings 17 # g 19 finally ensures a gaseous communication with the external environment.
