EP3266950B1 - Profile construction glass sheet with heat insulating properties, profile construction class assembly containing them and use of heat-insulating material - Google Patents

Description

The invention relates to a profiled glass web with heat-insulating properties, comprising a profiled glass web which has at least one web and at least one flange, and a heat-insulating material, a profiled glass arrangement comprising at least one row of profiled glass webs arranged next to one another, which comprise such profiled glass webs with heat-insulating properties, and the use of a heat-insulating Material for the production of a profiled glass web with heat-insulating properties.

Profiled glass webs fitted therein with dimensionally stable, translucent components, such as additional glass plates for mechanical stabilization or translucent capillary devices for thermal insulation, and such Profiled glass webs comprehensive Profiled glass assemblies are, for example, from EP 1 058 760 B1 or EP 0 742 34 B1 known. U-profile glasses with dimensionally stable, translucent capillary inserts are commercially available from OKALUX GmbH (www.okalux.com). Wacotech GmbH & Co. KG describes double-shell profile glass with translucent and light-diffusing thermal insulation made from a dimensionally stable glass web made of glass fiber/synthetic resin filament (brochure "TWD for profile glass - transparent thermal insulation" - www.wacotech.de).

Profilbauglasbahnen are formed in particular by glass profiles. In particular, U-glass profiles with a web and two flanges, which together form a U-profile, or L-profiles with a web and a flange on the side come into consideration for this purpose. They are assembled into U-shaped glass assemblies for glazing and buildings.

The U-shaped glass webs can be assembled as a single layer in a single row of U-shaped glass webs arranged next to one another and connected to one another. The lengths of profiled glass and the profiled glass arrangements then preferably have depressions which are open on one side and are formed by the web and a flange (when L-shaped glass profiles are combined) or two flanges (when U-shaped glass profiles are combined).

The profiled construction glass webs can still be joined together in double shells. In a double-shell construction, a first row of profiled glass webs and, parallel to this, a second row of profiled glass webs are joined together to form a two-row profiled construction glass arrangement, with the flanges of the first row and the flanges of the second row preferably facing each other. In the case of U-shaped channel glass sheets, the flanges may be butted or nested. In both configurations, cavities are created between the two rows of profiled glass webs, which are open at the end faces of the profiled glass webs.

For a three-shell or multi-shell formation of Profilbauglasanordnung further rows of Profilbauglasbahnen can be placed on a double-shell Profilbauglasanordnung, which depending on the alignment of the flanges of these Profilbauglasbahnen this bottle more cavities or open depressions.

From the EP 0 742 324 B1 it is known to provide transparent thermal insulation devices on the inside of the webs. For example, capillary packings, capillary plates, capillary tube packings or glass bead cluster packings are arranged for this purpose.

From the DE 203 19 907 U1 is known to arrange a bonded with a phenol-formaldehyde resin fiberglass wool insert with a compressible structure in the interior between U-shaped glass profiles. An assembly aid serves to fix the fiberglass wool insert to the glass profile before it is used in the facade.

The invention has set itself the task Profilbauglasbahnen and Profilbauglasanordnungen from the EP 0 742 324 B1 to improve known type in terms of thermal insulation and easier manufacture and assembly. A profiled glass web is to be formed with a thermal insulation device integrated into a profiled glass arrangement even before the profiled glass webs are installed, with which heat-insulated profiled glass arrangements and wall areas of buildings can be formed in a simple manner, while still being able to achieve a higher thermal insulation capacity than previously with such profiled glass arrangements. Furthermore, a kit of parts is to be formed which comprises a profiled glass web and a heat-insulating material in the form of a web or of cuts adapted to the surface of the profiled glass webs, in particular the inner surface of the web, which enables simplified thermal insulation of a profiled glass arrangement on a construction site.

To solve this problem, the invention proposes a profiled glass sheet according to claim 1.

Advantageous configurations of the invention are the subject matter of the dependent claims.

According to a first aspect, the invention provides a profiled glass web with heat-insulating properties comprising a profiled glass web which comprises at least one web with web inner surface and web outer surface and at least one flange with flange inner surface and flange outer surface, and a heat-insulating mat made of a flexible, fibrous polymer composite material having a thickness in the range from 5 mm to 20 mm and is attached to one or more of the inner surfaces and/or outer surfaces of the channel glass sheet.

It is further contemplated that the heat insulating mat made from a flexible, fibrous polymer composite material comprises glass fiber reinforced polyethylene terephthalate, methylsilylated silica and calcium silicate. Instead of PET, other duroplastic or thermoplastic polymers, such as polyethylene and polybutylene terephthalate, can alternatively be used.

It is preferred that the thermal barrier blanket of a flexible, fibrous polymer composite material be a thermal barrier blanket designated "HPI-1000 Building Insulation Blanket Grey" from Dow ^Corning® .

It is preferred that the heat-insulating mat is bonded to one or more of the inner surfaces and/or outer surfaces of the profiled glass web.

It is preferred that the heat-insulating mat covers one or more of the inner surfaces and/or outer surfaces of the profiled construction glass web over the entire surface or over part of the surface.

It is preferred that the heat-insulating mat comprises one or more cut-outs, which are adapted to the size of one or more of the inner surfaces and/or outer surfaces of the U-shaped glass sheet.

It is preferred that the profiled construction glass sheet is a U-shaped glass profile or an L-shaped glass profile, in which the heat-insulating mat is partially or completely connected to the inner surface of the web.

• eine oder mehrere Profilbauglasbahnen jeweils umfassend wenigstens einen Steg mit Steginnenoberfläche und Stegaußenoberfläche und wenigstens einen Flansch mit Flanschinnenoberfläche und Flanschaußenoberfläche und
• eine wärmedämmende Matte, die wie weiter oben definiert ist,

zur Verwendung für die dauerhafte Verbindung der wärmedämmenden Matte mit einer oder mehreren der Innenoberflächen und/oder Außenoberflächen der Profilbauglasbahnen auf einer Baustelle vor oder nach der Montage der Profilbauglasbahnen zu einer Profilbauglasanordnung.According to a further aspect, the invention provides a kit-of-parts comprising

• one or more profiled glass webs each comprising at least one web with web inner surface and web outer surface and at least one flange with flange inner surface and flange outer surface and
• a thermal insulation mat as defined above,

to be used for the permanent connection of the heat-insulating mat to one or more of the inner surfaces and/or outer surfaces of the profiled glass webs on a building site before or after the assembly of the profiled glass webs to form a profiled glass arrangement.

According to a further aspect, the invention provides a profiled glass assembly comprising at least one row arranged next to one another and with one another connected U-shaped glass webs, which consist entirely or partially of U-shaped glass webs with heat-insulating properties, as described above.

It is preferred that the profiled glass arrangement is constructed as a single shell from a single row of profiled glass webs arranged next to one another.

It is preferred that the profiled glass arrangement is double-skinned from a first row of profiled glass webs arranged next to one another and a second row of profiled glass webs arranged next to one another, with the flanges of the profiled glass webs of the first row and the second row facing each other and butting or interlocking and thus forming cavities, wherein the lengths of profiled glass in the first row and/or the lengths of profiled glass in the second row consist entirely or partially of lengths of profiled glass with heat-insulating properties as defined above. The cavities are formed between web inner surfaces and flange inner surfaces and are open at the end faces of the interacting profiled building glass webs and can be closed with closure devices.

Multi-layer profiled glass arrangements with cavities are used in EP 0 742 324 B1 which is incorporated herein by reference and is incorporated in the application documents. In EP 0 742 324 B1 the corresponding cavities are completely or partially filled with heat-insulating capillary devices. For preferred embodiments according to the present invention, instead of the thermally insulating capillary devices, blanks of a thermally insulating mat made of a flexible, fibrous polymer composite material, in particular made of "HPI-1000 Building Insulation Blanket Grey" from Dow Corning ^® , are inserted into the cavities formed from the web inner surfaces and flange inner surfaces, for example by gluing inserted. The heat-insulating mat usually fills the cavities only partially because of its small thickness. In the case of narrower cavities, the blanks from the heat-insulating mat can also be inserted into the shells when assembling them without gluing cavities resulting from the profile construction glass arrangement are inserted. They are then held in place by contact with the web inner faces and flange inner faces.

According to a further aspect, the invention specifies the use of a heat-insulating mat, which is as described above, for the heat insulation of profiled glass webs and profiled glass arrangements obtainable with them.

The profiled glass web can have a maximum glass length of preferably up to 700 cm. The face width of the U-profile glass web, which corresponds to the web width b, is as large as technically and statically possible. For example, it can be about 200 to 600 mm, preferably about 300 to 500 mm. A special bridge width is around 400 mm. With large web widths, the goal is pursued of maximizing the face width and minimizing the sealant joints, so that a maximum of daylight is obtained on the inside. The flange height h can preferably be in the range from 30 to 100 mm and is, for example, 60 mm. The glass thickness d is preferably 5 to 10 mm and is 7 mm, for example.

The permissible lower limit for the glass thickness d depends on the stability of the glass used. External thermal toughening leads to a significant increase in glass strength and allows the use of thinner glasses in more demanding situations, such as when exposed to strong wind loads. The thermal tempering enables a 5-fold increase in the profile glass, which is already strong due to its U-profile, and makes it possible, for example, to successfully use a 400 mm wide and 7 m long profile glass web.

The heat-insulating mat has a thickness in the range from 5 mm to 20 mm and is 10 mm, for example. It is dimensionally stable, but flexible and pliable and can, if necessary, be cut to the desired shape using simple means such as a knife.

The heat-insulating mat is cut according to the size of the surface of one or more of the inner surfaces and/or outer surfaces of the profiled glass web and preferably glued to the profiled glass.

With a thickness of preferably 10 mm, this heat-insulating mat HPI-1000 has a thin profile, is very flexible and at the same time stable under compression. Due to its composition, it has a high thermal resistance. It can be easily cut and conformed to complex shapes and tight curves. It sticks to buildings with no problem.

The HPI-1000 Building Insulation Blanket Gray product commercially available from Dow Corning ^® has the following properties: Characteristic HPI-1000 Building Insulation Blanket colour Gray thickness 10mm Thermal conductivity (ASTM C518) 0.0146W/mK R value (inch) 9.8 (h*ft ^2* F)/(Btu*in) U-value 0.58 W/m ² K per 25 mm thickness weight 0.31lb/ ^ft2 Maximum operating temperature 200ºC Compression Strength (ASTM C165) 10psi Fire resistance (ASTM E84) Class A: FSI 5, SDI 10 hydrophobic Yes moisture wicking small amount Permeability (ASTM E96) 2300 ng/Pa*m2 ^* s /41 US perms

The heat-insulating mat "HPI-1000 Building Insulation Blanket" is an object made of glass fiber reinforced PET with methylsilylated silica and calcium silicate. Base polymers other than PET, such as other thermoset or thermoplastic polymers such as polyethylene and polybutylene terephthalate, can also be used.

The silicic acid contained in the thermal insulation mat is a hydrophobic silicic acid obtained by methyl silylation of an untreated silicic acid becomes. The methylsilylation takes place, for example, with methylsilazanes. The silicic acids can be colloidal amorphous silicic acid including pyrogenic silicic acid and silicic acid produced in the wet process (precipitated silicic acid, silica gel).

The Dow Corning HPI-1000 Building Insulation Blanket thermal blanket is also featured in the Dow Corning ^® HPI-1000 Building Insulation Blanket - Thin-profile, flexible, high thermal resistance blanket ( ^© 2014 Dow Corning ^® ) and " Thin Insulation Blanket Solutions - Pack more energy efficiency into tight spaces with thin high-performance insulation" . It is also presented in a Safety Data Sheet according to Regulation (EC) No. 1907/2006 by Dow Corning ^® with SDS number 881455-0005 revised on 03/19/2016 and in an English language Safety Data Sheet with SDS number 905729-0005 , which was also revised on 03/19/2016.

The invention also relates to profiled glass arrangements comprising such profiled glass webs with heat-insulating properties, a kit of parts made from profiled glass web(s) without heat-insulating properties and a heat-insulating material, and the use of a heat-insulating material to produce such profiled glass webs and profiled glass arrangements.

The U-profile building glass web comprises a web 12 with web inner surface 14 and web outer surface 16 and two flanges 18 with flange inner surface 20 and flange outer surface 22. On the web inner surface 14 is a thermal insulating mat 24, such as the "HPI-1000 Building Insulation Blanket " mat from Dow Corning ^® glued on. A design with the same effect on the basis of a sheet of profiled glass with an L-profile, which also includes a web and an inner surface of the web for fastening the heat-insulating mat 24, is also possible.

The Profilbauglasbahn 10, 11 has a web width b of, for example, about 200 to 600 mm, preferably about 300 to 500 mm, here about 400 mm. The Profilbauglasbahn 10, 11 has a flange height h of about 30 to 100 mm, for example, about 60 mm here. The glass thickness d is preferably about 5 to 10 mm and is about 7 mm here. The glass thickness d depends on the desired stability of the profiled glass sheet and can be reduced with thermally toughened glass. The length of profiled glass 10, 11 can (not be seen in cross section) have a maximum glass length of preferably up to 700 cm.

The Profilbauglasbahnen 10, 11 are manufactured and designed, as from the company publication "Lamberts LINIT - Technical Introduction U-Glas", 6th edition, printer's note Lamberts / Linit TE 6 de / 012009 from September 2012 and / or in the general building authority Approval No. Z-70.4-44 of 12/21/2012 is described and shown. Both of these documents are incorporated herein by reference and form part of the disclosure herein.

The Profilbauglasbahn 10, 11 are formed for example from natural glass profiles, ornamental glass profiles, profile glasses with heat protection coating, sandblasted profile glasses, color enamel profile glasses, UV protection profile glasses, toughened profile glasses and / or prism profile glasses. The profiled glass 10, 11 can be provided with a prism structure on its web outer surface 16.

The Profilbauglasbahn 10, 11 according to 1 can be assembled into a single-shell 110 or double-shell 120, 130 to form a profiled glass arrangement 100. When assembled into a clamshell assembly 100, cavities 140 are formed within the assembly 100 for receiving the insulating mat 24 of a flexible, fibrous polymer composite material.

2 shows a single-layer U-profile glass arrangement 100 from a single row 110 of U-profile glass webs with heat-insulating properties 10. The side below the U-profile glass arrangement 100 corresponds to the outside 150, the side above the U-profile glass arrangement 100 corresponds to the building side 160. The flanges 18 point towards the building. However, the flanges 18 can also point outwards in the reverse arrangement. In addition, the profiled glass webs with heat-insulating properties 10 can be lined up in a sheet piling or hooked together. The profiled glass webs with heat-insulating properties 10 are fastened to a building, for example, via aluminum frame profiles (not shown) on the end faces of the profiled glass webs.

In the 3 The embodiment shown relates to a two-shell arrangement of profiled glass webs 10, 11, with only the profiled glass webs arranged on the outside 150 being profiled glass webs with heat-insulating properties 10. As an alternative or in addition, the webs of profiled construction glass can be equipped with heat-insulating mats 24 on the building side 160 . In this double-shell construction, the profiled glass webs 10, 11 are arranged in a butt-jointed manner via their flanges (flange-against-flange arrangement), whereby cavities 140 are formed. All Profilbauglasbahnen 10, 11 are connected via profile strips 180, such as cushion profiles, which have a total of four grooves into which the flanges of adjacent Profilbauglasbahnen 10, 11 of both shells 120, 130 can be inserted. For further details on the connection of the Profilbauglasbahnen 10, 11 with such profile strips 180 is on the document EP 0 742 324 B1 and the company publication "Lamberts LINIT -Technical Introduction to U-Glass" mentioned above.

In the 4 The embodiment shown relates to a two-shell arrangement of profiled glass webs 10, 11, with only the profiled glass webs arranged on the building side 160 being profiled glass webs with heat-insulating properties 10. It is also possible that the profiled glass webs are on the outside 150 profiled glass webs with heat-insulating properties 10 . The flanges of the profiled glass webs 10, 11 interlock (flange joints in pairs) and thus form cavities 140 for receiving the heat-insulating mat 24. The profiled glass webs are connected via profile strips 180. The shells formed from the two rows 120, 130 of profiled glass webs are additionally Silicone 190 sealed. For more details on this type of connection of the Profilbauglasbahnen 10, 11 is on the document EP 0 742 324 B1 and the company publication "Lamberts LINIT -Technical Introduction to U-Glass" mentioned above.
