Abstract
Przedmiotem zgłoszenia jest płyta z betonu licowego oraz sposób jej wytwarzania. Płyta zawiera masę betonową z czołową powierzchnią dekoracyjną. Płyta charakteryzuje się tym, że na powierzchni wewnętrznej warstwy licowej (1), przeciwległej do jej zewnętrznej powierzchni czołowej (2) ma naniesioną warstwę izolacyjną (3), zespoloną z warstwą licową (1) i stanowiącą integralną strukturę płyty o jednej tylko betonowej masie nośnej. W sposobie, w pierwszym etapie przygotowuje się warstwę licową (1) zespolonej płyty betonowej, wykorzystując prasę hermetyczną i stosując mieszaninę betonową, zawierającą następujące składniki w ilościach od do: piasek o O 0 - 2 mm, w ilości 1500 - 1550 kg/m3, mąkę kamienną lub pył O 0 - 0,5 mm, w ilości 350 - 400 kg/m3, cement RH 42,5, w ilości 450 - 500 kg/m3, plastyfikator w ilości 0,5 - 0,8% masy cementu, przygotowany surowiec wyjściowy prasuje się w prasie hermetycznej pod ciśnieniem 1400 t/m2 w temperaturze 30 - 40°C i w czasie 15 sec do 18 sec, w drugim etapie na płytę betonową nanosi się bezpośrednio warstwę izolacyjną (3) z poliuretanu zamknięto - komórkowego, wykorzystując prasę ciśnieniową z możliwością regulacji ciśnienia i temperatury, przy ciśnieniu od 134 kg/m2 do 154 kg/m2, temperaturze dozowania składnika A i B od 30 do 40°C, w czasie od 2,5 do 31/2 min, przy czym płytę betonową w formie utrzymuje się w temperaturze powierzchni aktywnej betonu od 20 do 30°C.The subject of the application is a facing concrete slab and the method of its production. The slab contains a concrete mass with a decorative front surface. The panel is characterized by the fact that on the inner surface of the facing layer (1), opposite to its outer face (2), there is an insulating layer (3), combined with the facing layer (1) and constituting an integral structure of the board with only one concrete support mass . In the process, in the first stage, the facing layer (1) of the composite concrete slab is prepared, using a hermetic press and using a concrete mixture containing the following components in amounts from to: sand of 0 - 2 mm, in the amount of 1500 - 1550 kg / m3, stone flour or dust O 0 - 0.5 mm, in the amount of 350 - 400 kg / m3, cement RH 42.5, in the amount of 450 - 500 kg / m3, plasticizer in the amount of 0.5 - 0.8% of the cement mass, the prepared initial raw material is pressed in a hermetic press at a pressure of 1400 t / m2 at a temperature of 30 - 40 ° C and during 15 sec to 18 sec, in the second stage an insulating layer (3) of closed-cell polyurethane is applied directly onto the concrete slab, using pressure press with adjustable pressure and temperature, at a pressure from 134 kg / m2 to 154 kg / m2, dosing temperature of component A and B from 30 to 40 ° C, during 2.5 to 31/2 min, the plate concrete in the mold is kept at p active concrete surface from 20 to 30 ° C.
