Description

Die Erfindung betrifft eine Einrichtung zur Entfeuchtung von Mauerwerk und dessen Fundament mit in das Mauerwerk sowie gegebenenfalls dessen Fundament einsetzbaren Elektroden sowie im Bereich von dessen Fundament in den Boden einsetzbaren Elektroden, die jeweils zum Anlegen einer elektrischen Spannung dienen, sowie mit einer Gleichspannungsquelle zum Anspeisen der Elektroden.The invention relates to a device for dehumidifying masonry and its Foundation can be used in the masonry and, if necessary, its foundation Electrodes and in the area of its foundation can be inserted into the ground Electrodes, which are used to apply an electrical voltage, as well as with a DC voltage source for feeding the electrodes.

Diese Einrichtung ist vor allem dadurch gekennzeichnet, daß die Gleichspannungsquelle mit einem Regler zum gepulsten Anspeisen der in das Mauerwerk sowie gegebenenfalls dessen Fundament einsetzbaren oder an das Fundament ansetzbaren Elektroden mit einer bezüglich des Erdpotentials negativen Gleichspannung sowie zum gepulsten Anspeisen der im Bereich des Fundaments des Mauerwerks in den Boden einsetzbaren Elektroden mit einer bezüglich des Erdpotentials positiven Gleichspannung ausgerüstet ist.This device is mainly characterized in that the DC voltage source with a controller for pulsed feeding into the Masonry and possibly its foundation can be used or attached to the Foundable electrodes with a negative earth potential DC voltage and for pulsed feeding the in the area of the foundation of the Masonry electrodes that can be inserted into the floor with respect to the Earth potential positive DC voltage is equipped.

Zur beispielhaften Erläuterung von erfindungsgemäßen Einrichtungen wird auf die Zeichnung Bezug genommen, in der Fig.3 eine Gesamtansicht, Fig. 2 eine Detailansicht einer Variante und Fig.1 ein Blockschema eines Steuergeräts einer erfindungsgemäßen Einrichtung zeigt.For an exemplary explanation of devices according to the invention, reference is made to the Drawing referred to, in Figure 3 an overall view, Fig. 2 is a detailed view a variant and Figure 1 is a block diagram of a control unit of an inventive Facility shows.

Zur Erläuterung der Gesamtanordnung wird vor allem auf Fig.3 Bezug genommen, die eine Mauer 19 mit Bodenfundament 20 zeigt, an deren einer Seite eine herkömmliche befahrbare Betonplatte mit Estrichabdeckung angeordnet ist, die nicht zum Fundament gehört. Der Übergang zwischen Mauer 19 und Fundament 20 ist etwa am oberen Niveau der Betonplatte, unterhalb der sich der Boden 21 erstreckt.To explain the overall arrangement, reference is made primarily to FIG shows a wall 19 with floor foundation 20, on one side of a conventional drivable concrete slab with screed cover is arranged that is not to the foundation heard. The transition between wall 19 and foundation 20 is approximately at the top Level of the concrete slab below which the floor 21 extends.

Nicht dargestellt sind übliche - und wie üblich defekte - Feuchtigkeitsvertikalsperren zwischen Mauer und Fundament sowie der Umstand, daß der Boden um das Fundament herum nicht natürlich vorhandenes Erdreich sein muß, sondern z.B. verdichtet und verfüllt sein kann - das ist Stand der Technik. Wichtig ist lediglich, daß der Boden im Bereich des Fundaments wie üblich am Erdpotential liegt und Flüssigkeitsaustausch mit der Umgebung gestattet.Common - and as usual defective - moisture vertical barriers are not shown between wall and foundation as well as the fact that the floor around the The foundation around it does not have to be naturally existing soil, but e.g. compressed and backfilled - that is state of the art. It is only important that the ground in the area of the foundation is, as usual, at the earth potential and Liquid exchange with the environment allowed.

An der Mauer 19 ist ein elektrisches Steuergerät 1 mit drei Ausgängen angeordnet.An electrical control device 1 with three outputs is arranged on the wall 19.

Der mauernahe Ausgang ist mit vier Mauerelektroden verbunden, von denen die Elektroden 14,15,16 in der Mauer angeordnet sind.The exit near the wall is connected to four wall electrodes, of which the Electrodes 14, 15, 16 are arranged in the wall.

In der Betonplatte ist eine Ausnehmung 18 vorgesehen, in die eine waagrechte Elektrodenhalteplatte eingesetzt ist, durch die hindurch drei Elektroden 11,12,13 nach unten in den Boden 21 ragen. Die mauernächste Bodenelektrode 11 ist gewinkelt und ihr anschlußfernes Ende steht in Kontakt mit dem Mauerfundament 20 - sie wird zusammen mit den Mauerelektroden 14,15,16 vom in Fig.3 mauerseitigen Ausgang des Steuergeräts 1 angespeist.A recess 18 is provided in the concrete slab, into which a horizontal Electrode holding plate is inserted, through which three electrodes 11, 12, 13 follow protrude into the bottom 21. The floor electrode 11 next to the wall is angled and its distal end is in contact with the wall foundation 20 - it will together with the wall electrodes 14, 15, 16 from the wall-side exit in FIG Control unit 1 fed.

Die beiden anderen Bodenelektroden 12,13 enden im Boden 21, wobei die mittlere Bodenelektrode 12 kürzer ist als die mauerferne Bodenelektrode 13. Die mittlere Bodenelektrode wird vom mittleren Ausgang des Steuergeräts 1, die mauerferne Bodenelektrode 13 vom mauerfernen Ausgang des Steuergeräts 1 angespeist.The other two bottom electrodes 12, 13 end in the bottom 21, the middle one Bottom electrode 12 is shorter than the bottom electrode 13 remote from the wall. The middle one Bottom electrode is from the middle output of control unit 1, which is remote from the wall Bottom electrode 13 fed from the wall-remote output of the control unit 1.

Die Bodenelektroden 11,12,13 sind im Bereich der Elektrodenplatte isoliert, die Enden sind blank. Der isolierte Bereich ist jeweils mit 10 bezeichnet.The bottom electrodes 11, 12, 13 are insulated in the area of the electrode plate, the ends are bare. The isolated area is designated 10 in each case.

Ebenso sind die Mauerelektroden 14,15,16 teilisoliert, ihre Länge nimmt mit abnehmender Höhe über dem Boden ab, um von oben beginnend den gesamten Mauerquerschnitt erfassen zu können.The wall electrodes 14, 15, 16 are also partially insulated, their length increases decreasing height from the ground to the whole starting from the top To be able to record the wall cross-section.

Die Elektroden 14,15,16 und 11 sind Kathoden (negativer als Erdpotential), die Elektroden 12,13 sind Anoden (positiver als Erdpotential). The electrodes 14, 15, 16 and 11 are cathodes (more negative than earth potential) Electrodes 12, 13 are anodes (more positive than earth potential).

Die Feuchte in der Mauer wandert beim Anlegen einer Gleichspannung von der Kathode zur Anode, also in der Mauer 19 vom Niveau der obersten Kathode 14 nach unten ins Fundament 20 und verläßt das Mauerfundament 20 unterhalb des untersten Niveaus der tiefsten Kathode 11 in Richtung der Anoden 12 und 13. Die Kathode 11 wird deswegen auch Niveaubegrenzungselektrode genannt, da die unterhalb dieses Niveaus vorhandene Feuchte im Fundament im Betrieb nicht mehr direkt erfaßt und daher nicht mehr abgeführt wird. Dies verhindert einen zu starken Wasserentzug aus dem Bauwerk, das sogenannte Übertrocknen, das Bauschäden verursachen kann.The moisture in the wall migrates from the when a DC voltage is applied Cathode to the anode, ie in the wall 19 from the level of the uppermost cathode 14 below into the foundation 20 and leaves the wall foundation 20 below the bottom Levels of the deepest cathode 11 towards the anodes 12 and 13. The cathode 11 is therefore also called level limiting electrode, because the one below it Levels of existing moisture in the foundation in operation are no longer recorded and is therefore no longer discharged. This prevents excessive water withdrawal the building, the so-called over-drying, which can cause structural damage.

In Fig.2 erkennt man, daß die Niveaubegrenzungselektrode 11 gemäß einer Variante in das Mauerfundament 20 hineinragt und bis dahin isoliert ist, also keine Bodenelektrode mit Fundamentkontakt, sondern eine zu den Mauerkathoden 14,15,16 zu zählende Fundamentkathode ist.In Figure 2 it can be seen that the level limiting electrode 11 according to a variant in the wall foundation 20 protrudes and is insulated until then, that is to say no bottom electrode with foundation contact, but one to be counted among the wall cathodes 14, 15, 16 Foundation cathode is.

Fig.1 gibt ein Blockschema des Steuergeräts 1 von Fig.1 wieder. Dabei ist 2 der Geräteanschluß 230 V Wechselstrom, 3 das Netzgerät mit Gleichstromausgang 24 V Gleichstrom, 4 der Regler mit einem Gleichstromausgang 1,5 - 24 V, 5 eine Zeitsteuerung zur gepulsten Kathodenansteuerung, 6 eine Zeitsteuerung zur gepulsten Anodenansteuerung und 7 der dreipolige Ausgang des Steuergeräts 1.1 shows a block diagram of the control unit 1 from FIG. 1. 2 is the Device connection 230 V AC, 3 the power supply with 24 V DC output DC, 4 the controller with a DC output 1.5 - 24 V, 5 a Time control for pulsed cathode control, 6 a time control for pulsed Anode control and 7 the three-pole output of control unit 1.

Man erkennt aus Fig.3, daß der Ausgang 7 keine Erdleitung aufweist.It can be seen from FIG. 3 that the output 7 has no earth line.

Nach dem Stand der Technik wird üblicherweise Mauerentfeuchtung durch Erzeugung eines Magnetfeldes durch Anlegen von Antennen oder Kupferspulen und ähnlichen Vorrichtungen, oder durch Anlegen von Spannung (thermisch aufbereitet) herbeigeführt. Derartige Entfeuchtungen bauen Magnetfelder auf oder verdampfen Feuchte im Mauerwerk. Die Salze, welche sich durch die aufsteigende Feuchte im Mauerwerk befinden, kristallisieren und verstopfen die Strömungswege, was wiederum zu einer baulich nachhaltigen Schädigung des Mauerwerks führt. Die Erfindung hat sich hingegen zum Ziel gesetzt, eine Einrichtung zum Trockenlegen von Mauerwerk und Fundamenten zu entwickeln, die effizient, mauerwerksschonend und energiesparend, ohne einen Magnetfeldaufbau, also nicht gesundheitsschädigend, arbeitet.According to the prior art, wall dehumidification is usually achieved by generation a magnetic field by applying antennas or copper coils and the like Devices, or brought about by applying voltage (thermally processed). Such dehumidifications build up magnetic fields or evaporate moisture in the Masonry. The salts, which are caused by the rising moisture in the masonry located, crystallize and clog the flow paths, which in turn leads to a structurally sustainable damage to the masonry. The invention has on the other hand, the goal is a facility for draining masonry and To develop foundations that are efficient, gentle on masonry and energy-saving, works without a magnetic field build-up, i.e. not harmful to health.

Dies wird erfindungsgemäß mit einer Einrichtung gemäß Anspruch 1 erreicht, für die nicht einschränkende Beispiele aus den Figuren zu erkennen sind.This is achieved according to the invention with a device according to claim 1, for which non-limiting examples can be seen from the figures.

Wie bereits erwähnt, werden vom Geräteanschluß (2) 230 V Wechselstrom an den Netzteil (3) geliefert. Vom Netzteil (3) wird die ausgehende Gleichspannung von 24 Volt an das Reglerelement (4) geliefert. Vom Reglerelement (4) wird die Gleichspannung je nach Durchfeuchtung und Größe des trockenzulegenden Objekts auf 1,5 - 24 Volt eingestellt, (ca. 0,8 Volt pro m zu erfassenden Radius, z.B. bei 6 m Radius 4,8 Volt, wobei für die Einstellung der Durchfeuchtungsgrad mit maßgebend ist und dementsprechend erhöht werden kann). Die Gleichspannung wird dann durch die Zeitsteuerung (5) negativ gepulst und durch dieZeitsteuerung (6) positiv gepulst, über den dreipoligen Ausgang (7) an die Elektroden wie in Fig.3 veranschaulicht weitergeleitet.As already mentioned, 230 V alternating current from the device connection (2) to the Power supply (3) supplied. The outgoing DC voltage of 24 Volt supplied to the control element (4). From the controller element (4) DC voltage depending on moisture penetration and size of the object to be dried 1.5 - 24 volts set, (approx. 0.8 volts per m radius to be recorded, e.g. at 6 m Radius 4.8 volts, whereby the degree of moisture penetration is also decisive for the setting and can be increased accordingly). The DC voltage is then through the Time control (5) pulsed negatively and pulsed positively by the time control (6), via the three-pole output (7) to the electrodes as illustrated in Fig.3 forwarded.

Gemäß der Erfindung wird u.a. auf üblicherweise weitreichende Verkabelungen und aufwendige flächendeckende (in Wand- oder Bodenbereich) installierte Elektroden verzichtet.According to the invention, i.a. on usually extensive cabling and elaborate surface-covering electrodes (in the wall or floor area) installed waived.

Beim Betrieb der erfindungsgemäßen Einrichtung wird Mauer- und Fundamentfeuchte in den Boden abgeführt, gleichzeitig aber auch Bodenfeuchte, die Erdpotential hat, zu den Bodenanoden hintransportiert, sodaß beim Betrieb die Wasserkonzentration dort gegenüber dem umgebenden Boden ansteigt. Es ist daher erfindungswesentlich, einen gepulsten Betrieb vorzusehen, um in den Betriebspausen einen Konzentrationsausgleich eintreten zu lassen - mit anderen Worten, auch eine Relaxationszeit für das behandelte System vorzusehen. Die Kriterien für die Wahl der Pulsung sind vielschichtig, werden aber hauptsächlich durch Bodenparameter (Beschaffenheit, Schichtaufbau, Durchlässigkeit etc.) gebildet.When operating the device according to the invention, wall and foundation moisture is in drained the soil, but also soil moisture, which has earth potential, to the Bottom anodes transported so that the water concentration there during operation increases compared to the surrounding soil. It is therefore essential to the invention, one pulsed operation to provide a concentration compensation during the breaks to let in - in other words, also a relaxation time for the treated System. The criteria for choosing the pulsation are multi-layered but mainly through soil parameters (nature, layer structure, Permeability etc.).

Eine derzeit bevorzugte Pulsfolge stellt sich - ausgehend von einer gleichzeitigen Anspeisung der Kathoden und Anoden zu einem gewählten Zeitpunkt (z.B. 0 h) wie folgt dar: Stunden EIN AUS Kathoden 5 3 mauernahe Bodenanode 6 2 mauerferne Bodenanode 2 6 A currently preferred pulse sequence - starting from simultaneous feeding of the cathodes and anodes at a selected point in time (for example 0 h) - is as follows: hours ON OUT cathode 5 3 Floor anode near the wall 6 2 Floor anode remote from the wall 2 6

Zusätzlich zur Anspeisungspulsung im Betrieb kann vorteilhaft auch eine Betriebspause in verschiedenen Intervallen vorgesehen sein, in der keine Elektrode angespeist wird. Vor Ende der Betriebspausen werden verläßliche Meßwerte über das Langzeitverhalten des Systems erhalten.In addition to the supply pulsing during operation, an operating break can also be advantageous be provided at different intervals in which no electrode is fed. Before the end of the breaks in operation, reliable measurements of the long-term behavior are made of the system.

Es ist bevorzugt, bei Erreichen eines tolerierbaren Feuchtewertes im Gebäude Betriebspausen von 2 Tagen pro Woche vorzusehen.It is preferred when a tolerable moisture value is reached in the building Operating breaks of 2 days per week should be provided.

Beim Anfahren der erfindungsgemäßen Einrichtung bei durchfeuchtetem Mauerwerk und Fundament ist nicht sinnvoll, die Niveaubegrenzungselektrode 11 gleich anzuspeisen, man kann bei den Kathoden von oben beginnen und fortschreitend Kathoden zuschalten.When starting up the device according to the invention with moist masonry and foundation is not useful, the level limiting electrode 11 is the same feed, you can start at the cathodes and progress Switch on cathodes.

Als Grundmaterial für die Elektroden wird Metall bevorzugt - insbesondere Nichteisenmetalle gegenüber Eisenmetallen. Derzeit wird erfolgreich mit Aluminiumelektroden gearbeitet. Die Isolierung besteht in üblicher Weise aus einer Kunststoffummantelung. Metal is preferred as the base material for the electrodes - in particular Nonferrous metals versus ferrous metals. Is currently successful with Aluminum electrodes worked. The insulation consists of a in the usual way Plastic coating.

Auf den Betrieb der erfindungsgemäßen Einrichtung haben weder Mauerwerksart, Mauerstärke noch Fundamentart und -stärke einen grundsätzlichen Einfluß - eine erforderliche Anpassung liegt im Können des Fachmanns, ebenso wie die Auswahl der Elektrodenanzahl und -anordnung. Die Länge der Bodenelektroden wird so gewählt, daß undurchlässige Bodenschichten überbrückt werden.Neither type of masonry, Wall thickness and foundation type and thickness have a fundamental influence - one The necessary adjustment lies in the skill of the expert, as well as the selection of the Number and arrangement of electrodes. The length of the bottom electrodes is chosen so that impermeable layers of soil are bridged.

Weiterhin kann natürlich auch lediglich eine begrenzte Entfeuchtung durchgeführt werden - in Weinkellern z.B. nur bis zu einer gewissen Tiefe unter Bodenniveau, und in Kenntnis der erfindungsgemäßen Einrichtung und ihrer Funktion ist dem Fachmann klar, daß bei einfacher Polungsumkehr der Einrichtung Durchfeuchtung vom Boden her durchgeführt werden kann - sollte ein Übertrocknungsschaden befürchtet werden oder zu beheben sein oder andre Gründe vorliegen.Furthermore, of course, only a limited dehumidification can be carried out - in wine cellars e.g. only to a certain depth below ground level, and in Knowledge of the device according to the invention and its function is clear to the person skilled in the art, that with simple reversal of polarity of the device moisture from the floor can be carried out - should over-drying damage be feared or to be fixed or there are other reasons.

Die Definition "Mauerwerk und dessen Fundament" ist nicht einschränkend - so wird z.B. auch die mauer- bzw. fundamentnahe Bodenplatte gemäß Fig.2 und Fig.3 darunter verstanden, die durch die erfindungsgemäße Einrichtung ebenfalls entfeuchtet wird.The definition "masonry and its foundation" is not restrictive - so it will e.g. also the floor slab near the wall or foundation according to Fig. 2 and Fig. 3 below understood, which is also dehumidified by the device according to the invention.
