Description

FIELD OF THE INVENTION

The invention relates to a profile for a glazing, such as a fixed glazing, an all-glass facade or a window, sliding door or insulating glazing, comprising an inside profile element, an outside profile element and a profile element extending between the inside profile element and the outside profile element in the width direction of the profile Plastic filler.

The invention further relates to glazing comprising a glass or composite glass pane and at least one profile according to the invention.

Finally, the invention also relates to a method for producing glazing whose profile system does not require condensate drainage.

STATE OF THE ART

Profiles for glazing, for example window or sliding door glazing, are often designed as multi-chamber systems in the prior art in order to ensure the best possible thermal resistance. For example, five-chamber profiles are used in connection with triple-glazed panes.

Since such profiles are not watertight, for example due to dry glazing, known profiles basically require a combination of rebate ventilation and drainage openings in order to be able to discharge condensation water that forms in the operating state from the profile. In order to comply with the provisions of ÖNORM B5300 in conjunction with those of ÖNORM EN 14351-1 (in each case in the one applicable on January 30, 2020 Version), a controlled drainage must be ensured. This is achieved in particular by a prescribed pull-up of 150 mm between the lower edge of the drainage openings and the upper edge of a water-bearing layer, such as a drainage channel, into which the condensation water is to be introduced.

These drainage specifications either prevent the profiles from being installed flush with the floor or require complex measures such as special convection heating.

OBJECT OF THE INVENTION

The object of the present invention is to provide a profile for a glazing, such as a fixed glazing, an all-glass facade or a window or sliding door glazing, which meets the requirements of ÖNORM B5300, ÖNORM EN 14351-1, ÖNORM EN 13049, ÖNORM B 3716-3, Section 6.2.1, as well as the draft of the guideline "Building waterproofing - connection to floor-to-ceiling windows and doors - Part 2: Execution", each in the version valid on January 30, 2020, is sufficient, with an interior and allows the profile to be installed flush with the ceiling and floor on the outside and requires neither condensate drainage nor convection heating.

Furthermore, it is an object of the invention to provide glazing which has the advantages mentioned above and to propose a method for its production.

DISCLOSURE OF THE INVENTION

An object of the invention is achieved with a profile of the type mentioned by the features of claim 1, with glazing of the type mentioned by the features of Claim 12 and achieved by the features of claim 15 in a method of the type mentioned at the beginning.

Advantageous embodiments are the subject of the dependent claims.

The profile according to the invention enables a standard-compliant sealing of a glazing, such as a fixed glazing or a thermal all-glass facade, due to the plastic filling part completely filling the accommodating volume over the entire length of the profile. In contrast to the prior art, the profile according to the invention does not have any chambers in which air could collect and condense at suitable temperatures; instead, the entire receiving volume of the profile is completely filled, so that, on the one hand, satisfactory thermal insulation is achieved and, on the other hand, the formation of condensation in the interior of the profile, in particular in the interior of the receiving volume, is reliably prevented. This leads to the fact that the profile according to the invention in the operating state in which it is inserted between an inner and an outer floor and also the other cavities of the profile - due to the use of a glass or composite glass pane, or a similar filling element, such as a sheet metal panel , a window element, or a double plug-in panel - are filled in accordance with the standards, completely leak-proof and protected from the formation of condensation. This means that there is no need for rebate ventilation and drainage openings, so that floor and ceiling-flush installation on the inside and outside is possible without having to provide convection heating or drainage channels.

In particular when the plastic filling part is glued and pressed to the two profile elements, namely the inside profile element and the outside profile element, the profile according to the invention exhibits particularly good thermal-insulating properties in the operating state. In addition, the formation of condensation inside the profile is particularly reliable, over particularly long periods of time and even when it is strong Stress on the profile or the corresponding glazing, for example due to heavy rain, is prevented. This effect can be further enhanced by providing toothed sections on the inside of the projections facing the receiving volume in order to give the plastic filling part a particularly strong hold by utilizing a barb function and to prevent the plastic filling part from becoming detached from one of the two profile elements.

Surprisingly, it has been shown that a profile is also suitable for standard-compliant use for glazing when its two profile elements are connected to one another by means of a plastic element made from an expanded polystyrene (EPS). A noticeable weight saving can thereby be achieved. In addition, the assembly of the profile is considerably simplified compared to known profiles, which leads to a reduction in costs.

The use of a sintered, highly compressed EPS has proven to be particularly advantageous in this context.

Particularly good strength properties or a particularly high dimensional stability of the profile can be achieved if the density of the expanded polystyrene is in the range from 100 to 400 kg / m3.

The expanded polystyrene preferably has a thermal conductivity in the range from 0.035 to 0.046 W / mK, particularly preferably 0.0459 W / mK, the thermal conductivity being determined in accordance with ÖNORM EN 12667 (in the version applicable on January 30, 2020).

The plastic filling part is particularly preferably made from COMPACFOAM® CF200.

This special EPS plastic has proven to be particularly advantageous in connection with those described above positive effects. In addition to reliably avoiding the formation of condensation inside the profile, a plastic filler made of this material also ensures a particularly dimensionally stable connection between the two profile elements. More detailed specifications of this material can be found in Table 1 in column CF200.

In a preferred embodiment, the inside profile element and the outside profile element are made of aluminum or an aluminum alloy, which aluminum alloy preferably consists mainly of aluminum.

By producing an anodized layer at least on the outside of the two profile elements, the profile can be reliably protected from weathering, especially when it comes into contact with a layer of lime in the masonry.

In a further preferred embodiment of the profile according to the invention, the inside Profile element and / or the profile element on the outside, a base profile part having the projections and a plug-in profile part detachably connected to the base profile part.

This greatly facilitates the installation or assembly of the corresponding glazing, since first the profile or a frame formed by several, for example circumferentially arranged, profiles is installed, then the glass or composite glass pane or another filling element conveniently into the profile or the frame can be used before the profile is completed by inserting the plug-in profile parts into the respective base profile parts and thereby the glazing is completed.

Preferably, a height section of the profile arranged in the vertical direction of the profile above the receiving volume, preferably adjoining the receiving volume, forms a glass support area for receiving at least one glass support, which glass support area is laterally closed by the inside profile element and the outside profile element.

In variants of the profile according to the invention, in which further height sections of the profile lie between the receiving volume and the glass support area, these height sections are also completely filled with a further plastic filling part of the type described above.

A preferred embodiment of the profile according to the invention has a connection area for connecting the profile to other structural elements and / or for mounting the profile on a substrate, which connection area is formed by a height section of the profile in front of the receiving volume in the height direction of the profile and laterally by the inside profile element and the outside profile element is complete.

In this way, the profile can be coupled or connected to other components in a simple and stable manner. aside from that The connection area also enables the standard-compliant support of blocks, for example support blocks, in order to store the profile construction in a stable manner on a sub-surface.

In the connection area, preferably at least one groove running in the longitudinal direction of the profile, preferably two parallel grooves, can be provided for receiving connecting elements, the inside profile element forming an inside groove wall and / or the outside profile element forming an outside groove wall each with a groove.

This allows the profile to be connected to other components in a particularly simple manner.

An object of the invention is also achieved by a glazing comprising a glass or laminated glass pane and / or other filling elements, such as sheet metal panels, as well as at least one profile of the type described above, with glass supports and at least one swelling band, which preferably surrounds the glass supports is to completely fill the glass support area of the profile over the entire length of the profile.

The glazing is thus reliably protected against the formation of condensation and does not require any drainage measures.

Thus, as is the case in a preferred embodiment, the glazing can be made completely tight. For this purpose, it is provided that the glass or laminated glass pane or the other filling element used in each case is mounted on two glass supports, with an inside joint between the inside profile element and the glass or laminated glass pane and an outside joint between the outside profile element and the glass or Laminated glass is sealed by means of wet glazing.

The glass supports are preferably made from an expanded polystyrene, preferably from COMPACFOAM® CF300, the strength of the glass supports being generally higher than the strength of the plastic filling part. More detailed specifications of this material can be found in Table 1 in column CF300.

This enables a more than sufficiently stable mounting of the glass or composite glass pane in the profile. At the same time, the glass supports thermally insulate the profile.

WAYS OF CARRYING OUT THE INVENTION

Fig. 1 shows a cross-section of glazing, which is orthogonal to a longitudinal direction of a profile 1, comprising the profile 1 according to the invention and a laminated glass pane 11 inserted into the profile 1.

The profile 1 comprises an inside profile element 2 and an outside profile element 3, which in turn is a base profile part (at reference number 3 in Fig. 1 ) and has a plug-in profile part 6 that can be inserted into this.

In a receiving volume, which is formed by a protrusion 5 (see Fig. 1 and 2 ) a limited height section of the profile 1 is formed, a plastic filling part 4 is arranged. The plastic filling part 4 is pressed with barbs 15, which are provided on the outer surfaces of the projections 5 facing the receiving volume, and glued by means of an adhesive layer 14 to the inside profile element 2 and the outside profile element 3, namely to its base profile part, namely in such a way that the Plastic filling part 4 completely fills the receiving volume, as far as technically possible. The term "completely filled" means in connection with the present invention that in the respective "completely filled" volume at most such cavities may remain which are not larger than 5 mm ³ , preferably not larger than 3 mm ³ , particularly preferably not larger than 1 mm ³ .

In a glass support area 7 adjoining the receiving volume in the vertical direction, at least two glass supports 9 are arranged, in the operating state of the profile, on which glass supports 9 the laminated glass pane 11 is supported in the profile 1; Exactly two glass supports 9 are used for each laminated glass pane 11. The inner volume of the glass support area 7 not occupied by the glass supports 9 is filled by swelling tape 10, which is arranged around the glass support 9 and can consist of several individual swelling bands. In this way, in the operating state of the profile 1, the glass support area 7 is also completely filled, as far as this is technically possible.

An inside joint between the inside profile element 2 and the laminated glass pane 11 and an outside joint between the outside profile element 3 or its plug-in profile part 6 and the laminated glass pane 11 is by means a wet glazing 12 is sealed in order to prevent water from entering the glass support area 7. The wet glazing 12 does not represent a maintenance joint because a joint width of at least 4 mm in each case ensures adequate flank adhesion; In addition, the wet glazing is drawn off at an angle of approximately 15 °, which also reduces the loads acting on the wet glazing 12.

Because the glazing is completely watertight in the operating state and condensation is prevented in the interior of the profile 1 due to the completely filled receiving volume or glass support area 7, no drainage agents are required in the profile 1. A flush installation of the profile 1 according to the invention with a floor 16 is thus possible without having to provide drainage channels or convection heating.

In order to be able to connect the profile 1 to other components and / or to be able to store it on a substrate, possibly with the interposition of appropriate storage blocks, the profile 1 comprises a connection area 8. The connection area 8 is in this case by a height section of the upstream of the receiving volume in the height direction of the profile 1 Profile 1 formed and laterally closed by the inside profile element 2 and the outside profile element 3 or its base profile part.

In the connection area 8, two parallel grooves 13 running in the longitudinal direction of the profile 1 are provided for receiving connecting elements, the inside profile element 2 forming an inside groove wall and the outside profile element 3 or its base profile part an outside groove wall in each case one of the grooves 13.

Overall, glazing that is framed with the profile according to the invention meets all the requirements of ÖNORM EN 14351-1, ÖNORM B 5300 (Resistance to wind load, tightness to driving rain, air permeability), ÖNORM EN 13049 and ÖNORM B 3716-3, Section 6.2.1 (load-bearing capacity under impact) as well as the draft of the guideline "Building waterproofing - connection to floor-to-ceiling windows and doors - Part 2: Execution" , in each case in the version valid on January 30, 2020. In particular, the backwater test was passed up to the top edge of the profile.
