Description

i DK 93 00146 U3in DK 93 00146 U3

Den foreliggende frembringelse angår en beskyttelsesindretning ved ildsteder i bygninger, især for støbe jernsovne og murede indbygningskaminer.The present invention relates to a protective device for fireplaces in buildings, especially for cast iron ovens and masonry fireplaces.

Hidtil er som oftest som beskyttelsesindretning ved 5 ildsteder anvendt stenplader. Ulempen ved disse stenplader består i, at man, inden man foretager en indbygning, først må fjerne den hidtidige gulvbelægning. På grund af en efterfølgende indbygning i gulvbelægningen forstyrres harmonien i den tidligere gulvbelægning. Også ved en efterfølgende ind-10 bygning af en kamin eller en ovn har det hidtil været et problem, at man ligeledes herved har måttet fjerne den oprindelige gulvbelægning, da kaminen eller ovnen af brandbeskyttelsesårsager ikke bør stå på den normale gulvbelægning.So far, stone slabs have usually been used as protective devices at 5 fireplaces. The disadvantage of these stone slabs is that, before making an installation, one must first remove the previous floor covering. Due to a subsequent incorporation in the flooring, the harmony of the previous flooring is disturbed. Also, in the subsequent installation of a stove or oven, it has hitherto been a problem that the original floor covering has also had to be removed, since the stove or stove should not stand on the normal floor covering for reasons of fire protection.

Kendt er også simple stål- eller blikplader, som ved 15 en efterfølgende indbygning af en åben kamin eller kakkelovn eller ved opstilling af en støbejernsovn simpelthen udlægges på den eksisterende gulvbelægning, idet ovnen eller kaminen placeres derpå, idet pladen rager fremefter foran eller eventuelt til siden i forhold til ovnen eller kaminen af 20 brandbeskyttelsesgrunde.Also known are simple steel or sheet metal plates which, upon subsequent installation of an open fireplace or stove or when erecting a cast iron oven, are simply laid on the existing flooring, the oven or stove being placed thereon, the plate projecting forward or possibly to the side. in relation to the stove or stove for 20 fire protection reasons.

Uanset at sådanne stål- eller blikplader optisk set ikke er særlig tiltalende, drejer dette sig mere eller mindre om en nødhjælpsforanstaltning.Although such steel or sheet metal is optically not particularly appealing, this is more or less a relief measure.

Det er formålet med den foreliggende frembringelse at 25 tilvejebringe en beskyttelsindretning for ildsteder og af den indledningsvis nævnte art, ved hvilken en efterfølgende indbygning af en kamin eller en ovn gøres mulig. Samtidig skal gulvfladens harmoni foran kaminen eller ovnen ikke forstyrres .It is the object of the present invention to provide a protective device for fireplaces and of the type mentioned in the preamble, by which a subsequent incorporation of a stove or oven is made possible. At the same time, the harmony of the floor surface in front of the stove or oven must not be disturbed.

30 I henhold til frembringelsen løses denne opgave ved hjælp af en foran og/eller under ildstedet anbringelig sikkerhedsglasplade med forøget temperaturbestandighed, bøjningsbrudstyrke, slag- og stødmodstandskraft.30 According to the present invention, this task is solved by means of a safety glass plate placed in front of and / or under the fireplace with increased temperature resistance, bending breaking strength, impact and impact resistance.

Ved denne sikkerhedsglasplade løses problemerne med 35 de hidtidige beskyttelsesindretninger. Sikkerhedsglaspladen kan anbringes uden bortrydning af et trægulv eller en anden gulvbelægning, f.eks. et tæppe. Sikkerhedsglaspladen er gennemsigtig som en normal glasplade, dvs. den tilpasser sig 2 DK 93 00146 U3 til rummet og antager gulvbelægningens farve. Den er dermed optisk mere tiltalende end en stenplade eller selv en stålplade, idet den ikke forstyrrer gulvets harmoni. Desuden er det en fordel med den lette rengøringsmulighed for sikker-5 hedsglaspladen. På grund af dens bøjningsbrudstyrke og dens modstandevne over for slag og stød kan den let modstå normale belastninger uden at gå i stykker.This safety glass plate solves the problems of the previous protective devices. The safety glass plate can be placed without removing a wooden floor or other floor covering, e.g. a blanket. The safety glass plate is transparent like a normal glass plate, ie. it adapts 2 DK 93 00146 U3 to the room and assumes the color of the flooring. It is thus optically more appealing than a stone plate or even a steel plate in that it does not disturb the harmony of the floor. Furthermore, it is an advantage of the easy cleaning option for the safety glass plate. Due to its bending breaking strength and its resistance to impact, it can easily withstand normal loads without breaking.

I henhold til frembringelsen sørges der tillige for, at sikkerhedspladen underkastes en varmebeskyttelsesbehand-10 ling.According to the production, the safety plate is also subjected to a heat protection treatment.

På grund af denne varmesbeskyttelsesbehandling opnår sikkerhedspladen en forøget temperaturbestandighed og be-lastbarhed med hensyn til temperaturpåvirkninger.Because of this heat protection treatment, the safety plate achieves an increased temperature resistance and loadability with respect to temperature effects.

En anden, meget væsentlig fordel i henhold til frem-15 bringeisen består i, at sikkerhedspladen efter fremstillingen opvarmes til dens bøjningstemperatur og derefter afkøles hurtigt.Another, very significant advantage of the production ice consists in the fact that, after manufacture, the safety plate is heated to its bending temperature and then cooled rapidly.

Denne behandling sikrer en høj bestandighed over for vekslende temperaturer, hvilket fremfor alt er væsentligt 20 ved gnistbeskyttelse. Den nævnte temperaturbehandling af pladen ligger ved ca. 900*C.This treatment ensures a high resistance to varying temperatures, which is above all essential for spark protection. Said temperature treatment of the plate is at approx. 900 * C.

En fordelagtig udformning af sikkerhedspladen kan be- stå i, at dens fladevægt ligger mellem 2,0 og 3,0 kg/m , og 2 fortrinsvis udgør 2,5 kg/m .An advantageous design of the safety plate may be that its surface weight is between 2.0 and 3.0 kg / m, and 2 is preferably 2.5 kg / m.

25 Denne værdi har i praksis vist sig særlig egnet.25 In practice, this value has proved particularly suitable.

I henhold til frembringelsen er sikkerhedspladen således udformet, at den tåler varige temperaturer på i det mindste 250*C.According to the production, the safety plate is designed to withstand lasting temperatures of at least 250 ° C.

Også dette er værdier, der i praksis har vist sig 30 særlig egnede.These, too, are values that in practice have proved particularly useful.

I henhold til en fordelagtig udførelsesform er resistensen mod temperaturgradienter i glasfladen mellem fladens midte og og fladens rand større end 100 K, fortrinsvis større end 150 K.According to an advantageous embodiment, the resistance to temperature gradients in the glass surface between the center of the surface and the edge of the surface is greater than 100 K, preferably greater than 150 K.

Også dette er værdier, der i praksis har vist sig at være særlig egnede.These, too, are values that have proven to be particularly useful in practice.

En anden fordelagtig videreudvikling af frembringelsen kan bestå i, at slagmodstandskraften af sikkerhedspladen 35 3 DK 93 00146 U3 over for stød fra bløde legemer er større end 80 Nm, fortrinsvis 100 Nm, og over for stød fra hårde legemer 25 Nm, fortrinsvis 30 Nm, uden at der opstår brud.Another advantageous development of the generation may be that the impact resistance of the safety plate 35 is greater than 80 Nm, preferably 100 Nm, and hard body shock 25 Nm, preferably 30 Nm, against impact from soft bodies. without any breakage.

Også dette er værdier, der i praksis har vist sig eg- 5 nede.These, too, are values that have proved suitable in practice.

I henhold til frembringelsen bør trykstyrken af sik- 2 kerhedspladen i det mindste være 700 n/mm .According to the generation, the compressive strength of the safety plate should be at least 700 n / mm.

Denne værdi for trykstyrken har i praksis vist sig at være fordelagtig.In practice, this value for compressive strength has proven to be advantageous.

10 En særlig fordelagtig udformning i henhold til frem bringelsen består i, at tykkelsen af sikkerhedspladen er 5 mm eller mere, fortrinsvis 6 mm.A particularly advantageous design according to the invention consists in that the thickness of the safety plate is 5 mm or more, preferably 6 mm.

Det er i denne forbindelse fordelagtigt, at sikkerhedsglaspladen på grund af den lille tykkelse ikke rager for 15 højt op over over det almindelige gulv, men alligevel yder en optimal sikkerhed med hensyn til gnistbeskyttelse, bestandighed over for temperaturændringer og bøjningsbrudstyrke .In this connection, it is advantageous that, due to its small thickness, the safety glass plate does not protrude too high above the ordinary floor, but still provides optimum safety with respect to spark protection, resistance to temperature changes and bending breaking strength.

I henhold til en konstruktiv udformning kan sikker-20 hedsglaspladen have slebne kanter og runde hjørner.According to a constructive design, the safety glass plate may have abrasive edges and rounded corners.

I henhold til frembringelsen kan der på sikkerhedsglaspladen være pålagt et mellemlæg af beskyttelsesfolie. Dette mellemlæg kan være fremstillet på keramikbasis og være asbestfrit.According to the production, a protective film can be placed on the safety glass plate. This shim can be made of ceramic and may be asbestos free.

25 Dette mellemlæg tjener som beskyttelse for pladens sikkerhed, når den opstillede ovn består af støbejern. En direkte berøring mellem stål og glas er nemlig i almindelighed problematisk.25 This shim serves as protection for the safety of the plate when the stove is made of cast iron. Direct contact between steel and glass is generally problematic.

En meget fordelagtig udformning af frembringelsen be-30 står i, at mellemlægget er forbundet med sikkerhedsglaspladen ved hjælp af et selvklæbende lag.A very advantageous design of the production consists in the fact that the spacer is connected to the safety glass plate by means of a self-adhesive layer.

På denne måde opstår der en sikker og skridsikker forbindelse mellem mellemlægget og sikerhedsglaspladen.In this way, a safe and non-slip connection is established between the insert and the safety glass plate.

Sikkerhedsglaspladen kan være udformet med mange for-35 skellige fordelagtige udformninger. Den kan f.eks. have form som et kvadrat, en firkant eller en mangekant.The safety glass plate may be formed with many different advantageous designs. It can e.g. have the shape of a square, a square or a polygon.

I en anden konstruktiv videreudvikling i henhold til frembringelsen kan sikkerhedspladen i det mindste tilnærmel- 4 DK 93 00146 U3 sesvis have form som en kvartcirkel eller en rundbue.In another constructive further development according to the invention, the safety plate may at least approximate in the form of a quarter circle or a circular arc.

I henhold til frembringelsen kan sikkerhedsglaspladen bestå af glat eller struktureret, forædlet glas.According to the production, the safety glass plate may consist of smooth or textured refined glass.

En meget fordelagtig udformning i henhold til frem-5 bringeisen består i, at sikkerhedsglasset består af et med serigrafi forsynet glas.A very advantageous design according to the production ice consists in the fact that the safety glass consists of a screened glass.

I henhold til en konstruktiv udformning af frembringelsen kan sikkerhedsglasset tillige bestå af et farvet emaljeret glas.According to a constructive design of the production, the safety glass can also consist of a colored enamelled glass.

10 Ved hjælp af en speciel forarbejdning af sikkerheds glasset sikres det, at den samlede plade i tilfælde af overbelastning opløses i et net af brudstykker med overvejende stumpe kanter, langs hvilke de kun er løst sammenhængende.10 By means of a special processing of the safety glass, it is ensured that in the event of overload, the entire plate is dissolved in a network of fragments with predominantly blunt edges, along which they are only loosely connected.
