Description
Vynález se týká způsobu vytváření vodonepropustných elektrovodivých clon v pevných stavebních hmotách s porézní strukturou za použití technických prostředků k potlačení kapilární vody v pórech stavebního matterálu a za současného vytvoření cesty pro difúzi vodních pair, pohybujících se hlavně vertikálním směrem meei atmosférou a prostory v podzákladí.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a process for producing water-impermeable electro-conducting screens in solid building materials with a porous structure using technical means for suppressing capillary water in the pores of a building material while providing a path for diffusion of water pairs.
Vysoušení zavlhlého zdivá budov s poškozenou, nebo chybějící horizontální izolací je dosud ve stavebnictví nedořešený problém. Složitost jeho problemmaiky souvisí s nehomogenitou zdivá. Staré zavlhlé zdivo je komminace, skláddjící se například z kamene šasto s malou ^Γον^αε^ nebo s póry o velmi maaýcУ průměrech, přččemi vrstvy mmlty jsou již odvápněné a převážně prostoupené dutinami s póry o poměrně velkých průměrech.Drying of damp masonry buildings with damaged or missing horizontal insulation is still an unresolved problem in the construction industry. The complexity of his problems is related to masonry inhomogeneity. The old, wet masonry is a com- mination consisting, for example, of a stone often of small size or with pores of very small diameters, which are already decalcified and largely permeated by cavities with pores of relatively large diameters.
Dalěí kommiikací při vysoušení zavlhlého zdivá je to, že se vlhkost pohybuje zdivém nejen ve skupenntví kapalném jako voda vzlínající, ale často ve formě vodní páry, která se sráží vvvitř nebo na povrchu zdivá a omítek a má velký poddl na celkovém zavlhčení zdivá. Kondenzační voda se v mnoha případech stává dνminuVícím faktorem, zejména tam, kde se používá vodotěsných podlahových krytin nebo pro vodu nepropustných - maateiálů na krytí chodníků a cest.Another commodity in drying damp masonry is that the moisture moves masonry not only in liquid form as rising water, but often in the form of water vapor that precipitates inward or on the surface of masonry and plaster and has a large deterioration in the overall masonry wetting. Condensation water in many cases becomes a determining factor, especially where waterproof floor coverings or waterproof materials are used to cover sidewalks and roads.
MLasické metody podřezávání zdivá a vkládání nové horizontální izolace jsou technicky .... i ekonomicky náročné a v některých případech i neprweddtelné pro nebezpečí statického narušení stavební konstrukce.The masonry methods of masonry undercutting and the insertion of new horizontal insulation are both technically and economically demanding and, in some cases, unpredictable due to the risk of structural damage to the building structure.
Ze stavební praxe jsou známé utěsňovací metody, při nichž se různými způsoby vpravuuí do zavlhlého zdivá látky, které maj za úkol ucpat transportní cesty v^3.ín^J:ící vody.Sealing methods are known from the construction practice in which, in various ways, they are incorporated into the wet masonry, which are intended to clog the transport routes in the water.
Nevýhodou těchto metod je, že porézní struktura pevných stavebních hmot zdivá se vyplní jen částečně. Velké póry se zmenší na mikropóry a póry s malými průměry zůstávají nadále otevřeny pro difúzi vodní páry a pro vodu v kapalném skupeansví.The disadvantage of these methods is that the porous structure of solid masonry building materials is only partially filled. Large pores are reduced to micropores, and pores with small diameters remain open for water vapor diffusion and for liquid water.
Pro potlačení vzlínajicí vody v mikropórech zdivá jsou velmi účinné elektroosmotické r metody. Se vzrůstajícím průměrem pórů se však účinnost elektroosmózy snižuje. Elektroosmoza také nezabrání průchodu vodních par zdivém.In order to suppress rising of water in micropores of the brickwork are very effective electroosmotic r methods. However, as the pore diameter increases, the electroosmosis efficiency decreases. Electro-osmosis also does not prevent the passage of water vapor through the masonry.
Uvedené nedostatky odstraňuje způsob vytváření vodonepropustných clon v pevných stavebních hmotách s porézní strukturou podle vynálezu, jehož podstatou je, že se do vrtů ve zdivu nejprve vpraví beztlakově nebo pod tlakem elektrrovodivá látka, například na bázi aluminia nebo ' jeho sloučenin, která utěsní póry zdivá o velkém průměru a zároveň vytvoří elektrodu pro připojení elektroosmotické instalace, potlačující kapilární vodu v mikropórech zdivá. Vrty ve zdivu se zevně propojí mezi sebou jednak vodičem elektroosmotické instalace, jednak podélným kanálkem v povrchové vrstvě zdivá, spojeiýfa s okoXnť. atmosférou, čímž se vytvoří cesta pro difúzi vodních par, polh^y^bujíctch se vertikálním směrem mezi prostory v podzákladí a atmosférou.[0007] The above-mentioned drawbacks are eliminated by a method of forming waterproof apertures in solid building materials having a porous structure according to the invention, which consists in first introducing into the boreholes in the masonry an electrically conductive substance, e.g. large diameter and at the same time create an electrode for connecting an electroosmotic installation, suppressing capillary water in masonry micropores. The boreholes in the masonry are externally connected to each other by the conductor of the electroosmotic installation and by the longitudinal channel in the masonry surface layer connected to the eye. atmosphere, thereby creating a path for the diffusion of water vapor, located vertically between the spaces in the subsoil and the atmosphere.
Vhodnou elektrovodivou injektážní látku představuje například vodný roztok s obsahem 30 až 45 % složek tvořících ve zdivu vodonepropustné gély, 7 až 15 % tydrofobntch látek, 1 až 5 t povrchově aktivních látek, 0,5 až 1,5 % fungicidních látek a 3 až 20 % přídavku koloidního uhlíku a am<^t^i^:rního hydroxidu.A suitable electroconductive grouting agent is, for example, an aqueous solution containing 30 to 45% water-impermeable gel-forming components, 7 to 15% tydrophobic substances, 1 to 5 t of surfactants, 0.5 to 1.5% of fungicides and 3 to 20% % addition of colloidal carbon and ammonium hydroxide.
Významným vedlejěím účinkem takto vytvářené vodonepropustné elektrovodivé clony je výměna vodíkových iontů za ionty . použitě elektrovodivá látky (například aluminia), která zvyšuj utěsňovací účinek injektážní látky a zvyšuj pevnost stavebního maaeriálu v tlaku.An important side effect of the waterproof impermeable screen is the exchange of hydrogen ions for ions. using an electrically conductive substance (e.g. aluminum) which increases the sealing effect of the injection substance and increases the compressive strength of the building material.
Také z ekonomického hlediska je způsob podle vynálezu výhodný, nebol vrt do zdivá je prostorem pro vpravení injektážní látky, slouží současně pro připojení elektroosmotické elektrody ve zdivu vzniklé a jako vennil pro difúzi vodních par.Also economically, the method according to the invention is advantageous, since the borehole into the masonry is a space for injecting substance injection, it serves simultaneously for the connection of an electroosmotic electrode formed in the masonry and as venom for water vapor diffusion.
Vrty, propojené mezi sebou elektricýfa vodičem, se připojí na jeden pól zdroje elektrického napětí. Druhý pól zdroje se připojí na zemní elektrodu nebo na druhou elektrodu ve zdivu, zhotovenou některým ze známých způsobů. Propojovací kanálek mezi vrty lze vynechat u objektů, .. které jsou podsklepené, a difúze vodních par mezi prostory v podzákladí a atmosférou může probíhat ve větraných suterénních místnostech.The bores connected to each other by a conductor are connected to one pole of the power supply. The other pole of the source is connected to a ground electrode or to a second electrode in the masonry, made by any of the known methods. The connection duct between the boreholes can be omitted for objects that are basemented, and water vapor diffusion between the basement and atmosphere can take place in ventilated basement rooms.
Příklad provádění podle vynálezuiDETAILED DESCRIPTION OF THE INVENTION
V nepodsklepené budově o tlouStce zavlhlého zdivá 75 cm provedla se po otlučení omítky těsně nad podlahou přízemí řada vrtů o průměru 15 mm, ve vzdálenostech od sebe 15 cm, do hloubky 9/W tlouStty zdivá. Úklon vrtů od horizontál roviny tyl 18°. Vrty se zaplnily elektrovodivou injektážní látkou. Po úplném vsáknutí předepsaného možžtví injektážní látky byl v úrovni vrtů uložen na zdivo meealický vodič a přichycen na zdivo cementovou mátou· Metalický vodič se zavedl ke kladnému pólu zdroje elektr^kého napětí 2 Volty. Záporný pól zdroje elektrického nap^í byl propojen na zemní elektrodu běžného provedení známého ze slabliroudé a silnoproudé elektrotechniky. V úrovni vrtů nad podlahou se up^^^i^n^^a lišta z PVG-mataeiálu malé výšky tvaru U, která měla propojení na chodbě přes větrací mřížky s okolní atmosférou a při dokončovacích pracích se zamítala novou omítkou. Tři týdny po provedené instalaci byl zapojen. zdroj elektr^kého na kladnou a zápornou elektrodu.In a cellarless building with a thickness of 75 cm wet masonry, after plastering just above the ground floor floor, a series of boreholes with a diameter of 15 mm, at a distance of 15 cm apart, to a depth of 9 / W masonry was made. Tilt of boreholes by d horizontal plane of tulle 18 °. The boreholes were filled with an electroconductive grout. After fully absorbing the prescribed grout, a meealic conductor was placed on the masonry at the borehole level and attached to the masonry with cement mint. The metallic conductor was led to the positive pole of the 2 Volt power supply. The negative pole of the power supply was connected to a ground electrode of conventional design known from low-current and high-current electrical engineering. At the level of the boreholes above the floor, a small U-shaped PVG material with a connection in the corridor through the ventilation grilles with the surrounding atmosphere was clamped up and the new plaster was rejected during the finishing work. Three weeks after the installation was involved. a source of electrical for the positive and negative electrodes.
V příkladu popsaná elektrovodivá clona vykazuje oproti jiným znivým metodám k vytváření htriztotáloíih izolací nejen vySTší izolační účinek, ale je též jednodušší a levnější, protože eleCtrovldivá ^e^ážní látka plní současně dvě funkce, tj. utěsňuje velkou Část pórů zdivá a tvoří zároveň souvislou δiгoklpltěnou eleCtroo8mtticktu elektrodu pro potlačení vzlínajicí vody v mikropórech zdivá.The electro-conducting screen described in the example exhibits not only a higher insulating effect, but is also simpler and cheaper compared to other apparent methods for making vertical insulation, but it is also simpler and cheaper, since the electro-conductive substance fulfills two functions simultaneously, ie sealing a large portion of pores electrode for suppressing rising water in micropores masonry.
