Working method and arrangement of dipoles or the like Renovation of structures at risk of moisture

The invention relates to a working method and an arrangement of dipoles Qd * like electrical conductors for the renovation of structures endangered by moisture, preferably with thick walls to prevent the water flow rising from the bottom to the top in the structures so that the Dry out affected structures naturally

The effect of in a masonry endangered by moisture » The electric fields formed on the flow of liquid are so strong that they can be safely switched off Fields, if it succeeds, brings about an effective weakening of the water rise in the masonry «The Dyna- ' This has a decisive influence on the water transport, in that more water evaporates from above than what is demanded from below. as the abolition of the mas sen balance of the transported liquid quantities from " presses

Masonry treated in this way can - based on the Time unit - at the top, a larger amount of water is released into the outside air through evaporation than is absorbed from the groundwater in the same time unit, so that the soaked masonry dries out naturally "

All until now applied the so-called electro-osmotic ^{n Ä} process for Bauwerkstrockenlegung therefore generally based on the principle of eliminating the in the. Electric fields developed in masonry or on the build-up of opposing electric fields

However, in principle all these known methods and arrangements have the same weakness that the electrodes are always inserted in the masonry according to a certain arrangement scheme, for example by a multitude of -electric conductors made of different metals with different potentials of the electrochemical Voltage series in two levels (so-called blocking levels) arranged roughly parallel above and below one another and are connected in an electrically conductive manner · On the actual spatial, ie · different distribution of the electrical fields formed in the wall in three dimensions of the tree, as is well known, there will be no Consideration

Due to this scheme of the arrangement, the area of aaximal field strength gradients in the wet-endangered buildings is not recorded in the Hegel, and the influence of the vertical liquid transport is made purely by chance · a reliable statement about the achievable The blocking effect of such measures is therefore - especially in the case of thick-walled structures - according to known methods and arrangements not yet possible

In contrast, the invention aims to eliminate the above-described main deficiency of all so-called electroosmotic locking methods used so far

The invention is based on the object of providing dipoles or electrical conductors in such a way in structures that are at risk of moisture install that with certainty the range of maximum field strength gradients are recorded by the dipoles introduced into the structures, so that a targeted, maximally weakening influence on the vertical liquid transport in structures at risk of moisture is achieved.

According to the invention this object is achieved in that in the ones to be drained, for example dioc-walled, Structures with spatially variable electrical potentials in their water-bearing area first include the area different charge carrier concentrations and then the plateau of the electrical potential can be measured without it, e.g. by measuring the height and spatial distribution of these electrical potentials as well as the respective wallioke

The actual spatial position and structure of the electrical fields formed in the buildings are then determined, for example by entering them in appropriate scale drawings or sketches or by providing the buildings themselves with appropriate markings and the like. Then the dipoles are distributed over the cross-sections of the structures or walls to be renovated According to the invention, the amount and the location are determined and the distribution of the preferably rod-shaped dipoles provided with anti-corrosion coatings according to these measurement results described above.

That happens by now the electrically not with each other related dipoles, different in mass and spatial arrangement or concentration, for example with different lengths and different distances between the dipoles, according to the actual spatial structure and concentration of the electrical formed in the buildings Fields to be arranged in the water-bearing areas of the structures at risk of moisture The arrangement and mass distribution of the dipoles is based on calculations based on exact Measurement results are based, so that with certainty the Areas of maximum field strength gradients from the introduced Dipoles are penetrated in such a way that the free electrical charges contained in the dipoles get to the points of maximum load carrier concentration in the structures »

Such measurement results are included in these calculations, such as statements about the tertiary components of the electric fields formed in the buildings and about the Water volume in the wet areas · The physical parameters determined in this way become Calculation of the optimal material usage quotient with exact information on mass and chemical composition and spatial distribution of the dipole material, based on the unit volume of the structures penetrated by the water and on the unit of area in the horizontal plane of the building or through which the vertical water ascent passes Masonry cross-sections used · Optimizing the mass and spatial concentration the dipoles in the structures is calculated based on a product that is derived from the required minimum use formed at dipoles for the determined plateau potential and the quotient of the peak and plateau potential will·

It should be noted that the dipoles represent the terrain plane enforce and in the thick-walled structures, starting from their opposing boundary surfaces, in each case at least bia towards the center of the wall, sohrag from directed upwards downwards, are installed · The vertical projection of the length of the dipoles must be done be at least 1.2 meters, and there must be at least four dipoles of this length per square meter of cross-section of the building - measured at the height of the terrain. With the method according to the invention and the arrangement of the dipoles according to the invention, the concentration areas of the electrical charge carriers are in those at risk of moisture Buildings, as sources of electric fields and contributors to vertical water transport, turned off, so made ineffective, so that now auoh thick-walled wet-endangered buildings with a lot of space variable electrical potentials of their water-bearing areas can be successfully drained,

The invention is to be explained in more detail below using an exemplary embodiment.

To determine the dipoles to be introduced into the masonry endangered by moisture, the height and spatial distribution of the electrical potential in the damp areas is first measured.Then the plateau / O of the electrical potential / in this area of the masonry is determined.Then the upper evaporation limit is determined and finding out the position of the maximum potential · At the points of increased electrical potentialay ⁷ .

In the masonry, the material insert M is then

preferably by reducing the mutual dipole spacing according to the operating instructions,

proportionally increased

The more the potential / ^, the closer the sequence η to be the dipole »

for this arrangement of the dipoles in moisture-prone areas The following pre-installation tool applies to the masonry

1 Every dipole must enforce the terrain plane

2 · The vertical projection of the length of the dipoles must be at least 1.2 meters the dipoles are no more than 0.5 meters apart

3 · The amount of dipole material used should be at least 1H _Q »4.2 kg, based on the square meter of the transverse wall surface, measured at the height of the terrain.

4 · In the case of longer dipoles, the distance between neighboring dipoles must not exceed 0.4 times the be the perpendicular projected length of the dipoles

Basically, the following is to be observed:

- Ss must not be a horizontal contiguous area from A Z 0.5 m that is not penetrated by at least one dipole

- Where the measured electrical potential differences have their maxima, each must horizontal surface A »·· m be penetrated by at least one dipole ·

- With thick masonry, the dipoles must be longer and you must keep the material constant Distance can be larger

- If the electrical potential is higher, the use of material (number of dipoles per unit area) can be increased proportionally
