Stavebně konstrukční prvek
CZ 17495 Ul
Stavebně konstrukční prvek
Oblast techniky
Technické řešení se týká stavebně konstrukčního prvku obsahujícího lisovaný drcený materiál na bázi buničiny, zejména papíru.
Dosavadní stav techniky
Vrstvené potravinářské obaly, tj. obaly zhotovené z papírové nebo jí podobné hmoty, jejichž stěny jsou alespoň z jedné, obvykle základní strany pokryty vodu nepropouštějící fólií, převážně z plastu nebo hliníku či jeho sloučenin, jsou používány pro balení kapalin. Jsou využívány zejména v potravinářství, např. kartónové obaly ve tvaru čtyřstěnu, známé jako tetra-obaly či obaly tetrapak, sloužící pro prodej mléka, ovocných šťáv, apod. Obaly uvedeného druhu jsou rovněž používány pro maloobchodní balení průmyslových kapalin. Vrstvené materiály představují na jedné straně výborný balicí prostředek, na druhé straně problém z hlediska odpadů, neboť se jedná o obaly nevratného charakteru a použitá fólie velmi omezuje, ne-li, vylučuje, jejich recyklaci pro výrobu nových obalů.
Účelem tohoto technického řešení je nejen likvidace odpadu výše uvedeného druhu, ale jeho zpracování na výrobky, které najdou široké uplatnění.
Podstata technického řešení
Výše uvedeného účelu je dosaženo stavebně konstrukčním prvkem podle tohoto technického řešení, jehož podstata spočívá v tom, že je opatřený alespoň jednou základní vrstvou z lisované drtě vrstvených potravinářských obalů, pokrytou plastovou fólií a vnějšími krycími vrstvami. S výhodou je použita drť obsahující částice o velikosti nejvýše 3 cm. Krycí vrstvou může být papír nebo podobný materiál. Pro použití jako obkladový materiál je předmětný prvek opatřen alespoň jednou mezivrstvou z tepelně izolujícího materiálu, s výhodou z polystyrenu, vloženou mezi základní vrstvy. Dále podle tohoto technického řešení je krycí vrstva opatřena povrchovou vrst25 vou, s výhodou hliníkovou fólií.
Výhodou tohoto technického řešení je využití jinak nepotřebného odpadového materiálu k výrobě stavebně konstrukčních prvků, které jsou jak hygienicky, tak zdravotně nezávadné, bez emisí těkavých látek, a vykazují nízkou nasákavost. Prvky mají velmi široký rozsah použití, jak je dále uvedeno.
Přehled obrázků na výkrese
Technické řešení je dále podrobněji objasněno na příkladech jeho praktického provedení. Na přiloženém výkrese je na obr. 1 schematicky nakreslena skladba jedné desky a na obr. 2 je schematicky znázorněno složení panelu zhotoveného podle předmětného vzoru.
Příklad provedení
Vhodným materiálem jsou použité obaly typu tetrapak. Základní surovina, obaly tetrapak z komunálního sběru, je po vytřídění nečistot podrcena na frakce do velikosti pod 30 χ 30 mm a nadrcené částice projdou postupně pračkou a sušičkou. Základní vrstva 1, z vyčištěné drtě je rovnoměrně nanesena na podložku, např. papírovou, která tvoří první krycí vrstvu 2, a upěchována. Pak je volná plocha vrstvy drtě překryta plastovou fólií 3 a je přiložena druhá krycí vrstva 2.
Plastová fólie 3, např. z polyethylenu, vytváří pojivo mezi základní vrstvou 1 a krycí vrstvou 2. Po slisování při teplotě 160 až 190 °C následuje lisování za studená. Hotová deska o tloušťce asi 10 mm se naformátuje na požadovanou velikost, např. na rozměr 2800 χ 1200 mm.
-1 CZ 17495 Ul
Takto zhotovená deska, pokrytá z obou stran papírovou krycí vrstvou 2, má měrnou hmotnost kolem 800 kg/m3, součinitel tepelné vodivosti 0,08 W/m.K, pevnost v ohybu kolem 5,5 MPa, stupeň hořlavosti Cl, je tedy obtížně hořlavá. Prvek je hygienicky a zdravotně nezávadný, bez emisí těkavých látek. Vykazuje sníženou nasákavost a vysokou odolnost proti průsakům vody přes průřez mimo hrany.
Konstrukčně stavební prvek ve tvaru desky, je určený k obkladům v interiéru. S následnou povrchovou úpravou, např. keramickým, či jiným obkladem nebo tenkovrstvou omítkou, jej lze použít i pro exteriéry. Deska je vhodná jako podklad pro podlahové systémy nebo jako ochranný krycí materiál.
ío Výše popsaný, základní konstrukčně stavební prvek podle tohoto technického řešení, který má tvar desky, může být rovněž použitý jako polotovar pro stavebně konstrukční prvek ve formě panelu sendvičového typu. Takový panel se skládá z několika výše popsaných desek, proložených mezivrstvou 4, nejlépe z tepelně izolačního materiálu. Styčné plochy desek jsou natřeny vhodným lepidlem, a po vložení mezivrstev je celek slisován. Pro daný účel vhodným tepelně izolačním materiálem je např. polystyren.
Příkladem takového prvku podle tohoto technické řešení je panel složený ze dvou výše popsaných desek, má tedy dvě základní vrstvy 1, mezi něž je vložena jedna mezivrstva 4 z polystyrenu, např. o tloušťce 40 mm, případně 100 mm. Jiným příkladem je panel složený z pěti dílů, z nichž tři tvoří výše popsané desky, tedy tři a mezi nimiž jsou vloženy dvě mezivrstvy 4 z polystyrenu.
Lícová strana takového panelu může být opatřena další povrchovou úpravou, např. může být pokiyta povrchovou vrstvou 5 ve formě hliníkové nebo plastové fólie, která dále může, ale nemusí být pokryta ozdobným vzorem.
Obdobně jak je výše popsáno využití obalů typu tetrapak, lze pochopitelně použít též jiné materiály podobných vlastností.
Průmyslová využitelnost
Předmětné technické řešení je určeno pro likvidaci komunálního odpadu a výrobu stavebně konstrukčních prvků.
