Description

145633145633

Opfindelsen angår et anlæg til tørlægning og tør-holdelse af bygværker, der er gennemfugtede af opstigende fugt fra den omgivende jord eller grundvandet.The invention relates to a plant for drying and drying of structures that are soaked in rising moisture from the surrounding soil or groundwater.

Anlægget er af den art, som har metalliske ledere 5 i form af folier, blik, trådnet, gitre eller stænger indført i et eller flere hovedsagelig vandrette, ledende forbundne lag i f.eks. et murværk.The plant is of the kind which has metallic conductors 5 in the form of foils, tin, wire mesh, grids or rods inserted into one or more mainly horizontal, conductively connected layers in e.g. a masonry.

Oven over terrænet fordamper fugtigheden, men på grund af osmotisk tryk, kapillaropsugning og elektri-10 ske feltkræfter stiger der til stadighed ny fugtighed op, fremfor alt fra grundvandet. Imellem disse kræfter og tyngdekraften indstiller der sig en dynamisk ligevægt. Derfor stiger fugten heller ikke op til vilkårlig højde, men kun til 2-3 meter over terrænet.Above the terrain, the moisture evaporates, but due to osmotic pressure, capillary suction and electric field forces, new moisture is constantly rising, especially from the groundwater. Between these forces and gravity, a dynamic equilibrium is established. Therefore, the moisture does not rise to arbitrary height, but only to 2-3 meters above the terrain.

15 Der kendes fremgangsmåder til svækkelse af de elektriske kræfter eller til helt at fjerne dem, hvilke fremgangsmåder er kendt under betegnelsen "elektroosmotiske fremgangsmåder".Methods are known for attenuating the electrical forces or for removing them altogether, which methods are known as "electroosmotic methods".

Ved de passive elektroosmotiske fremgangsmåder 20 indskydes der i bygværkerne elektriske ledere, som forbindes elektrisk ledende med grundvandet med henblik på en udligning af de bestående elektriske potentialforskelle.In the passive electro-osmotic methods 20, electrical conductors are inserted in the construction works which are connected electrically conductive to the groundwater in order to offset the existing electrical potential differences.

Ved de aktive elektroosmotiske fremgangsmåder 25 indskydes der imellem de i bygværket indskudte elektriske ledere og grundvandet en elektrisk strømkilde med henblik på at fremskynde nedbrydningen af de elektriske potentialforskelle.In the active electroosmotic methods 25, between the electrical conductors inserted in the construction and the groundwater, an electric power source is inserted to accelerate the breakdown of the electrical potential differences.

Ifølge en anden kendt fremgangsmåde installeres 30 der i bygværket elektriske ledere, som består af to forskellige metaller i den elektrokemiske spændingsrække. De forbindes indbyrdes på en sådan måde, at de i fugtige bygværker danner et galvanisk element.According to another known method, electrical conduits consisting of two different metals in the electrochemical voltage series are installed in the structure. They are interconnected in such a way that in damp structures they form a galvanic element.

De efter disse elektroosmotiske fremgangsmåder 35 i bygværker anbragte elektriske ledere virker som elektroder i en elektrolyt. Da de gennemstrømmes af en elektrisk strøm, udsættes de for stærke elektroerode- 145633 2 rende nedbrydningsprocesser og må derfor fornyes fra tid til anden, for at de kan opfylde deres funktion.The electrical conductors arranged in these structures according to these electroosmotic methods 35 act as electrodes in an electrolyte. As they are flowed by an electric current, they are subjected to strong electrodegradable degradation processes and must therefore be renewed from time to time in order to fulfill their function.

En anden ulempe ved de kendte elektroosmotiske fremgangsmåder består i, at elektroderne anbringes i 5 bygværket efter et bestemt skema. Det er derfor kun sjældent, at det med sikkerhed og vedvarende lykkes at modvirke den påvirkning, som de elektriske felter, der findes i alle områder af det fugtige bygværk, og som til stadighed skifter med hensyn til retning og styrke, 10 har på fugtvandringen.Another disadvantage of the known electroosmotic methods is that the electrodes are placed in the structure according to a certain scheme. It is therefore only rare that it is possible, with certainty and sustained success, to counteract the influence of the electric fields found in all areas of the damp building, which are constantly changing in direction and strength, 10 on the moisture migration.

Det tilsigtes med opfindelsen at tilvejebringe et ubegrænset virksomt anlæg til tørlægning og tørholdelse af bygværker.It is an object of the invention to provide an unlimited effective plant for drying and drying of construction works.

Den opgave der ligger til grund for opfindelsen, be-15 står i at forhindre den nedbrydning af de indsatte elektriske ledere, som skyldes elektroerosion.The object of the invention is to prevent the degradation of the inserted electrical conductors caused by electrical erosion.

Denne opgave løses ifølge opfindelsen ved, at de metalliske elektriske ledere har indbyrdes samme materialesammensætning og er elektrisk isoleret fra murvær-20 ket, og at anlægget udelukkende består af de i murværket indførte, indbyrdes ledende forbundne elektriske ledere, der således er uden strømtilførsel og jordforbindelse.This task is solved according to the invention in that the metallic electrical conductors have mutually the same material composition and are electrically insulated from the masonry, and that the plant consists exclusively of the electrical conductors introduced into the masonry, which are thus without power supply and grounding. .

Herved afskærmes et bestemt område af bygværket fra elektriske felter. I det indre af metallerne optræ-25 der der ikke noget elektrisk felt. Under indflydelse af ydre elektriske feltkræfter vandrer de frie ladningsbærere i feltlinjernes retning hen til overfladen af metallet og forbliver her, så længe der eksisterer et ydre elektrisk felt. I det af metal omsluttede eller opfyldte 30 rum kan det ydre elektriske felt heller ikke trænge ind, selv om dette rum ikke omsluttes af en fuldstamdigt lukket metallisk overflade. Det ydre elektriske felts feltlinjer ender hele tiden vinkelret på den metalliske overflade.This shields a certain area of the building from electric fields. There is no electric field in the interior of the metals. Under the influence of external electric field forces, the free charge carriers migrate in the direction of the field lines to the surface of the metal and remain here as long as an outer electric field exists. In the metal enclosed or filled compartment, the outer electric field cannot penetrate either, although this compartment is not enclosed by a fully-sealed metallic surface. The field lines of the outer electric field always end perpendicular to the metallic surface.

35 I det af metal omsluttede eller med metal gennem- trængte bygværk virker der derfor ingen elektriske feltkræfter, hvorfor den heri værende fugtighed kan 145633 3 strømme væk i tyngdekraftens retning, således at det pågældende bygværk tørrer ud lidt efter lidt. Den fugtighed, der stadigvask findes oven over det afskærmede bygværksparti, stiger under indflydelse af det elektri-5 ske felt, som stadig eksisterer her, opad og fordamper.35 In the metal enclosed or metal-penetrated building work, therefore, no electric field forces work, so the moisture contained therein can flow away in the direction of gravity, so that the building in question dries out little by little. The moisture still present above the screened building portion increases under the influence of the electric field, which still exists here, upward and evaporating.

Da der ikke kan strømme ny fugtighed til, tørrer også dette område ud. Neden under det afskærmede bygværksparti samler fugtigheden sig. Metalafskærmningen skal derfor hele tiden nå ned til det område af bygværket, 10 som til stadighed holdes fugtigt af det omgivende grundvand.Since no new moisture can flow, this area also dries out. Below the sheltered structure, the moisture accumulates. The metal shielding must therefore always reach down to the area of the building, 10 which is constantly kept moist by the surrounding groundwater.

Da de elektriske felter altid forløber imellem de områder, hvor fugtigheden trænger ind, og de områder, hvor den fordamper, behøves der kun en metalafskærmning 15 i disse to retninger.Since the electric fields always run between the areas where the moisture penetrates and the areas where it evaporates, only a metal shield 15 is needed in these two directions.

Forbindelsen imellem de metalliske ledere i ét plan og de metalliske ledere i andre planer kan være tilvejebragt på den ene eller på begge sider af bygværket eller pi3 en sådan måde, at de går vertikalt eller 20 diagonalt igennem det pågældende bygværkpsparti.The connection between the metallic conductors in one plane and the metallic conductors in other planes may be provided on one or both sides of the building or pi3 in such a way that they pass vertically or diagonally through the relevant building work portion.

De elektriske ledere, som er anbragt i horisontale planer, og de elektriske ledende forbindelser mellem disse består som nævnt af det samme metal. Herved undgår man, at der opstår elektriske spændinger imellem lederne, 25 som kan forårsage elektroerosion.The electrical conductors arranged in horizontal planes and the electrical conductive connections between them consist, as mentioned, of the same metal. This prevents electrical voltages between the conductors, which can cause electrical erosion.

De metalliske ledere installeres'i mørtelfuger, i borehuller eller i slidser. Ved nybygninger bliver de elektriske ledere, der skal anbringes i et plan, indlagt i form af folier, plader, trådnet eller metalgitre, hvis 30 dimensioner svarer til bygværkets tværsnit, i de horisontale mørtelfuger og forbundet elektrisk ledende fra plan til plan. Ved eksisterende bygværker installeres der fortrinsvis stavformede metalliske ledere i borehuller.The metallic conductors are installed in mortar joints, in boreholes or in slots. In new buildings, the electrical conductors to be placed in a plane are laid in the form of foils, sheets, wire mesh or metal grids, the dimensions of which correspond to the cross-section of the building, in the horizontal mortar joints and connected electrical conductor from plane to plane. For existing structures, rod-shaped metallic conductors are preferably installed in boreholes.

De fordeles jævnt over bygværkets tværsnit, anbringes i 35 et gitter og forbindes elektrisk ledende fra plan til plan, eller de bliver anbragt på en sådan måde, at de går vertikalt eller diagonalt igennem begge planerne,They are evenly distributed over the cross-section of the building, placed in a grid and connected electrically conductive from plane to plane, or they are arranged in such a way that they pass vertically or diagonally through both planes.
