Definitions

  • the invention relates to a reinforcing or supporting element for building materials, in particular electrodes designed as a plaster base for electroosmotic dehumidifying devices with a reticulated supporting body, and a method for the electroosmotic movement of polar liquids in porous solids (masonry or the like) by applying an electrical voltage between Electrodes, using such reinforcement or support elements.
  • Reinforcing or supporting elements for building materials consist of rod-shaped or net-shaped or lattice-shaped materials.
  • reinforcement of concrete structures mainly mats or grids made of structural steel or as a plaster base, mainly fine metal grids are used. If the metal grids are used as a plaster base, they are often coated with fired ceramic materials to ensure better adhesion of the plaster mortar.
  • the disadvantage of these metallic Plaster carriers that, due to different pH values, they are exposed to corrosion in the building and the different moisture conditions. In many cases, the arrangement of the grids in zones with different pH values leads to the formation of a galvanic element and thus to a field structure which causes the structures to be destroyed or the moisture to be drawn up from the ground into the structures.
  • the electro-osmotic processes use the phenomenon of electro-osmosis to slow down the moisture rising in the capillaries of the masonry and to push it down.
  • Polarization occurs at the interface between water and a solid, with a negative charge on the surface of the solid and a positive charge on the liquid particles.
  • This charge normally occurs Not appearing, migration occurs only in an electrical field, whereby the solids (insofar as they are mobile) migrate to the positive anode (also known as electrophoresis), the liquid particles, especially if the solid particles are prevented from moving, strive to migrate to the negative cathode.
  • DE-OS 27 06 172 proposes electrodes with additional foils to prevent corrosion.
  • the voltage that can be used in the active process is limited by the decomposition voltage, depending on the composition of the masonry and the salinity of the water, since electrolysis is caused by decomposition of the water Gases were generated that must destroy the components in which the electrodes are installed, such as plaster.
  • DE-OS 27 05 814 could be caused by oxyhydrogen formation even pose an explosion risk, so that a limit of 2.8 V is required.
  • the invention is based on the object of creating a reinforcing or supporting element for building materials of the type mentioned at the outset which can also be used in areas with different or changing pH values and which enables an intimate connection with the building materials which give them.
  • this reinforcement or support element at the same time as an electrode for a dehumidification system working on an electroosmotic basis.
  • the prerequisite is created that when using the reinforcing or supporting elements as electrodes, even in the case of large-scale systems and at higher operating voltages, no disturbances due to electrolytic decomposition or hydrogen deposits on an anode can occur.
  • the decisive factor here is the continuous coating of the mesh with conductive plastic. Thanks to the flexibility of the network, it can be easily adapted to different environmental conditions, such as different floor levels or building levels. This advantage comes to the fore especially when used for the renovation of dampened building structures. Since the coating of the mesh with the conductive plastic causes the voltage to be distributed uniformly over the entire surface of the electrode, a large-area electrokinetic effect, for example large-area electroosmosis, is achieved.
  • the plastic forming or surrounding the mesh for example an acrylate, has at least partially cross-linked polymers a high surface roughness and a low plasticizer content, and preferably with an oxygen-reducing metal, eg titanium, boron, is doped.
  • the high waiter Surface roughness has the advantage that there is an intimate connection of the surrounding building materials, in particular the plastering mortar with the network.
  • the low plasticizer content it is achieved that this intimate connection is also maintained and there is no shrinkage on the circumference of the network, so that even for a long time a perfect contact with the surrounding construction materials, especially when using the reinforcing elements as electrodes for dehumidification systems, is guaranteed is.
  • the permanent contacting is additionally increased by the use of oxygen-doped metals-doped plastics, since the passivation of the anode network is switched off.
  • the plastic surrounding the thread-like carrier material has semiconductor properties and a relatively low carbon content, the carbon components being freely suspended in the plastic.
  • the use of a plastic having semiconductor properties is distinguished by the fact that the charge transport takes place through electrons and holes, in contrast to the so-called ion semiconductors, in which mass transport is associated with the charge transport.
  • the conductivity in the temperature conditions occurring in building structures is advantageous for the use of such reinforcing or supporting elements for building materials. Since the carbon components in these semiconductors do not have to form a skeleton in order to increase the conductivity, it is possible to find sufficiency with a low carbon component, as a result of which the fragility of such plastic coatings is reduced.
  • the network is assigned power supply lines which are formed by lanyards composed of a plurality of flexible individual strands. This enables an evenly continuous con Tacting the network when using the reinforcing element as an electrode or it is advantageously possible, when using the reinforcing or supporting elements according to the invention, to contact them retrospectively at any time to build up electrical fields in building structures, for example to install horizontal barriers for moisture insulation or the like .
  • the power supply line is made of carbon threads or metal threads, e.g. made of titanium or the like, since this improves the power supply lines, the strength of the networks against mechanical stresses and at the same time the conductivity.
  • the use of titanium is distinguished by the small electrochemical potential difference compared to hydrogen, so that the risk that a galvanic element can build up is additionally reduced.
  • the power supply line it is also possible for the power supply line to be arranged in the longitudinal direction of a band-shaped network and approximately centrally between the longitudinal edges of the network. This ensures an even power supply to the various power supplies and, above all, easily damages bridged power supplies.
  • the mesh size is adapted to the building material surrounding the network and preferably has a mesh size of 5 mm in the form of a plaster base. This makes it possible to adapt the reinforcement or support elements to their area of application, so that the network cannot be damaged when the building materials are introduced.
  • the network is elastic and back is designed to be spring-free, in particular made of flexible plastic, since this greatly simplifies the plastering or incorporation of the reinforcing elements into the building materials and allows them to be well adapted to the surfaces of the building bodies.
  • the counter-pole switching element it is also possible for the counter-pole switching element to have a pulse switch arranged in parallel with smoothing diodes of a rectifier circuit, from which an input at the negative pole of a DC voltage source and the output of which is connected to a supply line to the anode, a closing contact of the pulse switch being applied via a timing element .
  • a pulse switch arranged in parallel with smoothing diodes of a rectifier circuit, from which an input at the negative pole of a DC voltage source and the output of which is connected to a supply line to the anode, a closing contact of the pulse switch being applied via a timing element .
  • Such a circuit can be produced very easily in the different technologies, such as relay control, transistor control or with integrated switching components set so that a simple adaptation to the different applications and environmental conditions is easily possible.
  • the invention also encompasses a method for the electroosmotic movement of polar liquids in porous solids (masonry or the like) by applying an electrical voltage between electrodes, using net-shaped supporting bodies of a reinforcing or supporting element for building materials.
  • This method is characterized in that the voltage applied is a voltage alternating between positive and negative potential, in which the time integral of the positive voltage is greater than that of the negative voltage, the positive voltage preferably being greater than the negative voltage.
  • the feature of the larger positive time integral enables the desired electroosmotic effect, while the negative voltage eliminates any substances formed by electrolytic decomposition, in particular the unfavorable gases, in a reverse reaction.
  • the high concentration of the substances produced at the eel electrodes leads to a rapid and preferred reversal of the chemical processes, while the build-up of the reversed electric field and thus the reversal of the electroosmotic effect is reduced or completely prevented.
  • the method according to the invention for different time integrals can be demanded by different time components and / or different voltages of the positive and negative voltage components.
  • the AC voltages represent a sinusoidal voltage with a mains frequency with a reduced negative voltage.
  • the voltage peak of the negative period can be cut off or only the part of the sine voltage exceeding a certain voltage can be used. It is particularly advantageous here that this is very easily realized by semiconductors.
  • a support body 1 which serves as a reinforcing or supporting element for building materials.
  • This support body 1 is designed as a network 2.
  • a power supply line 3 is integrated, which is formed by a conveyor belt 4.
  • the power supply line 3 is arranged in the longitudinal direction - arrow 5 - of the band-shaped network 2 approximately centrally between the two longitudinal edges 6.
  • the Lahnband 4 consists, as indicated over part of its length, from a plurality of individual strands 7, which are formed by metal thread 8.
  • the surface of the metal threads 8 can be silver-coated, or e.g. Titanium wire is used to obtain a good conductivity and a small potential difference between the surface of these metal threads 8 and the plastic 9 surrounding them. If the potential difference is small, then an electromotive force can hardly be formed between the different materials, such as silver or titanium and the plastic 9 according to the invention, and therefore no current flows. However, this does not lead to metal degradation, especially of those metals that have a more negative intrinsic potential, so that no ions go into solution.
  • a support body 10 is shown, which is formed by a network 11.
  • the individual threads 12 to 14 of the network 11 consist of a plastic 15.
  • This plastic 15 is essentially ion-free and is designed in the manner of a thermoset with a macromolecular structure.
  • This plastic 15 is preferably, for example, an acrylate with at least partially crosslinked polymers, which has a high surface roughness and a low proportion of plasticizer.
  • the plastic 15 can preferably be designed in accordance with the Austrian patent specification 313 588 from the same inventor. It is advantageous if the plastic is doped with oxygen-reducing metals. When using a network 11 with a plastic doped in this way 15 as an anode, the oxidation of the anode and its passivation is switched off.
  • a power supply line 18 is formed by a thread 14 of the network.
  • metal threads 14E or carbon threads 17 are arranged in these mesh threads 14 to increase the conductivity, but also in addition to increase the mechanical strength, which can optionally be provided with a silver coating 19.
  • This silver coating achieves the advantages already described in connection with FIG. 1.
  • any plastic 15 which is highly elastic, flexible or limp and conductive, in the manufacture of the network 11.
  • the entire network is covered with the plastic 15 to produce the desired surface quality of the network 11, as is indicated in the region of the crossing threads 12 and 14 of the network 11.
  • FIG. 3 shows a section through a thread 13 of the net 11 on an enlarged scale.
  • 13 metal threads 16 or carbon threads 17 are embedded in the plastic 15 of the thread, some of which are provided with a silver coating 19.
  • 15 plastic constituents 21 are freely suspended in the plastic. This free-floating arrangement of carbon constituents 21 is possible because the plastic 15 has semiconductor properties and the carbon is therefore not required to build up a line system, but only to increase the conductivity.
  • FIGS. 4 and 5 show two different design variants as to how the support bodies 1 or nets 2 or 11 according to the invention can be arranged on structures 22 and 23, respectively.
  • the building structure 22 or 23 consists, for example, of brick masonry or reinforced concrete in the exemplary embodiments shown.

  • the two networks 24 and 25 are arranged one above the other in the vertical direction on the outside of the building body.
  • the grid 25 forming the cathode 36 is arranged in the bottom 39, a change of soil advantageously taking place in the area of the net 25, so that porous, highly water-draining layers are arranged in the area of the net.
  • the net 24 forming the anode 35 on the base 24 is due to a thickness 40 of the structure 23 the inside of the building facing side of the structure 23 and the grid 25 forming the cathode 36 attached to the outside thereof.
  • the network 25 is again arranged in the region of the bottom 39 and when the two networks 24, 25 are applied to the DC voltage source 30, an intense electrical field 41 is created, which is indicated schematically by field lines 42.
  • the moisture travels within the structure 23 in the direction of the cathode or is prevented from rising in the structure 23 by the moisture 38 rising in the foundation.

  • the advantage of using the grids of the invention as reinforcing or - a supporting element for building materials lies mainly in the fact that by the specific used plastic material, due to the high surface roughness and low shrinkage, over a long period an intimate bond between the structural material and the reinforcing element exists, whereby moisture accumulations in the area of the reinforcing elements and thus subsequent corrosion are switched off and a high electrical conductivity of the system is achieved when using the network as electrodes.
