Abstract
Podstata vynálezu je v tom, že sa na dekoračnú vrstvu kameniva alebo inej drvy, rozprestretú na dno formy, pritavuje folia z termoplastu tak, aby pri dobrej súdržnosti s dekoračnou vrstvou a betonovým prefabrikátom ostala jej súvislosé neporušená.The essence of the invention is that a thermoplastic foil is fused onto a decorative layer of aggregate or other crushed stone spread on the bottom of the mold so that, with good adhesion to the decorative layer and the concrete precast, its continuity remains intact.

Vynález rieši spósob finálnej povrchové] úpravy prefabrikátov pri leh výrobě ve formě.The present invention provides a method for the final surface treatment of prefabricated components in a mold production process.
Doterajšie sposohy finálnej úpravy povrchov prefabrikátov sypanou drvou z prírodnéhokameniva, skla, keramiky a podobné sa obmedzovali na nanášenie tejto drvy na hornú plochučerstvo zabetonovaného prefabrikátu, alebo až po jeho odformovaní dodatočne na ktorúkolvek je-ho stranu. Na dno formy sa dali ukládat len keramické alebo sklená mozaika alebo hrubsie frak-cie oblázkov, ktoré sa po odformovaní čistili vymýváním fixačnej hmoty alebo ešte nie celkomzatvrdnutého cementového pojivá. Nevýhodou spósobu finálnej úpravy z o sypanej drvy nanášanejpri výrobě len na hornú plochu je to, že u značnéj časti plášťových prefabrikátov vytvárasa ich líc na dne formy, čo vyžaduje ich úpravu sypanou drvou dodatočne až po odformovaní, U vymývanej povrchovej úpravy z oblázkov alebo drvy je vysoká pracnost a nerovnorodost. 1'ieto nedostatky odstraňuje sposob finálnej povrchové] úpravy'prefabrikátov napříkladkamenivom alebo lnou drvou, sypanou na dno formy podlá vynálezu, ktorého podstata je v tom,že na rozprestretú dekoračnú vrstvu například z kameniva alebo inej drvy pritavuje sa eštepřed betonážou folia z termoplastu tak, že pri jej dobrej súdržnosti s rozprestretou deko-račnou vrstvou i betonom ostala jej súvislost neporušená.Previously, the finishes of the finishing of the prefabricated surfaces with crumbs of natural stone, glass, ceramics and the like have been limited to the application of this crumb to the upper flattening of the concreted prefabricated element, or only after it has been demoulded on either side. Only the ceramic or glass mosaic or the coarser fraction of the pebbles that had been purged after demoulding by washing the fixative mass or not yet fully cured cement binder could be deposited on the mold bottom. The disadvantage of the method of final treatment from bulk powder applied only to the production of the upper surface is that in the case of a large part of the prefabricated elements, they form their face at the bottom of the mold, which requires them to be sprinkled with crushed material after the molding. labor and inequality. These drawbacks are eliminated by the final surface treatment of the pre-fabrics, for example by means of a stone or flax pulp, poured onto the bottom of the mold according to the invention, whereby the thermoplastic foil is applied to the spreading layer, e.g. that with its good coherence with the spreading layer and the concrete, its continuity remained intact.
Pritavením folie z termoplastu na dekoračnú vsrtvu například z kameniva alebo inej drvy,docieli sa nielen jej stabilizácia, ale aj vodotěsnost potřebná na zabránenie zatiekaniabetonu pod dekoračnú vrstvu. Tým vznikne celkom čistý umývatelný líc prefabrikátu. Okrem uvede-ných výhod je možnost zvyšenia dekoračného účinku kombináciou kame'niva s farebnou fóliou,čo je doteraz možné len s použitím farebných cementov. Vodotěsnost a umývateΪnost finálnejpovrchovej úpravy prefabrikátov umožňuje ich použitie ako stěnové panely a priečky pre vnú-torné priestory s mokrou prevádzkou. Pri stále sa zlepšujúcej kvalitě folií z termoplastov aich odolnosti proti atmosférickým vplyvom, dá sa očakávat podstatné predlženie životnostia tým aj ich ekonomické] výhodnosti.By fusing the thermoplastic film to a decorative layer, for example, of aggregate or other crumbs, not only its stabilization is achieved, but also the waterproofness required to prevent the concrete from arresting under the decorative layer. This results in a completely clean washable prefabricated face. In addition to the aforementioned advantages, it is possible to increase the decorative effect by combining the stone with the colored film, which is only possible with the use of colored cements. The watertightness and washability of the prefabricated surface finish allows them to be used as wall panels and partition walls for wet areas. With continuously improving the quality of thermoplastic films and their resistance to atmospheric influences, a substantial extension of their service life and their economic advantage can be expected.
Ako možnost konkrétného příkladného využitia spósobu finálnej povrchovej úpravy prefab-rikátov podlá vynálezu třeba uviest výrobu kompleti zováného parapetného panelu z keramickýchtvárnic s podpovrchovými venti 1ačnýrni- prieduchmi, ktoré eliminujú vysoký difúzny odpor vodo-tesnejfolieztermoplastuAs an example of a particular application of the method of final surface treatment of prefabricates according to the invention, it is necessary to provide the production of a complete window sill panel made of ceramic blocks with subsurface ventilators which eliminate the high diffusion resistance of the water-tight foil.
Na dno formy sa na rozprestretú dekoračnú vrstvu plameňom, infražiaričmi alebo horúcimvzduchom pritaví folia z termoplastu tak, aby pri dobrej súdržnosti s dekoračnou vrstvou ostalajej súvislost neporušená a nanesená spojovacia malta a beton nezatiekli na dno formy. Zlepše-nie súdržnosti medzi pritavenou fóliou a dekoračnou vrstvou možno dosíahnut napuštěním kameni-va alebo drvy vhodným penetračným roztokom alebo postrekom folie.Thermoplastic foils are attracted to the bottom of the mold by the flame, infrared or hot air on the spreading decorative layer so that, with good adhesion to the decorative layer, the continuity remains intact and the bonding mortar and concrete do not flow into the bottom of the mold. Improving the consistency between the fused film and the decorative layer can be achieved by impregnating the stone or crumb with a suitable penetration solution or spray film.
Aplikácia tejto finálnej povrchovej úpravy na vnútornej straně parapetného keramickéhopanelu je velmi výhodná, alebo vytvára parotesnú zábranu na vnútornej straně stěnového pane-lu. •Pre zlepšenie súdržnosti fólie s betonovým prefabrikátom možno na pritavovanú foliurozptýlit a zatavit zrnitý alebo ihličkovitý, popřípadě vláknitý posyp. Pre zvyšenie účinkumožno dekoračnú vrstvu z farebného kameniva alebo drvy ukládat pomocou šablon podlá fariebdo obrazov, ornamente? alebo textu.The application of this final surface treatment on the inner side of the window sill panel is very advantageous or creates a vapor barrier on the inner side of the wall panel. In order to improve the cohesion of the foil with the prefabricated concrete, a granular or needle-like or fibrous grit can be dispersed and sealed to the foliar flux. To increase the effectivity of the decorative layer of colored aggregates or crushes can be stored using templates according to color, ornament? or text.
