A process for using the device of the invention is also described.

Description

The invention relates to a device for introducing a curable liquid, especially a capillary water lock, in an absorbent solid, preferably in a Masonry, in concrete or in wood, with a liquid containing reservoir and one with the reservoir flow-connected outlet device for the delivery of the Liquid in at least one formed in the solid Drilling. Furthermore, the invention relates to a method for Introducing a curable liquid, especially one Capillary water barrier in an absorbent solid preferably in masonry, in concrete or in wood, under Ver application of a device according to the invention.

The invention relates generally to the renovation of Solids caused by rising moisture in their sub are threatened. Most of these are rising moisture in masonry or concrete walls. These a building-threatening rising dampness is the Horror of every homeowner. Often introduces gradual "creeping up" of moisture in the masonry a reduction in the quality of living and even a complete breakdown malfunction of the building. Inside the living rooms modern Walls the wallpaper, wooden parts rot and it forms Sponge and mold colonies. Finally, even fall Plaster and parts of the masonry. Salt and lime are formed efflorescence that is difficult or impossible to cover up let it

Most contained in masonry or in a concrete wall Building materials have pores and capillaries that ver are bound. Consequently, this is an open poro sity. Does it come as a result of the age-related degradation of the New construction from the outside or after the protective layer  Damage to groundwater entering the Kel walls, it can be used for horizontal and vertical transfer moisture, especially on higher-lying buildings parts, come, provided there is a horizontal barrier above the earth rich is not available or does not work. The water is then caused by capillary forces - within the pores, cracks or capillary - forwarded. The climbing height of the Water up to a few meters.

From the registered documents of the German utility model G 84 35 438.0 is already a procedure for introducing a curable liquid in an absorbent solid knows, here also drill holes in a masonry will. As a storage container for the capillary Water barrier liquid will be used with a bottle uses a vent closure. Through this A closure tube is passed through, which extends from the Extends inside the bottle to the outside, with the area of the spout located outside the bottle chens is insertable into the hole. In the area of the closure ses a cross hole is formed that the inside of the off connecting tube with the interior of the bottle.

In practice, there is also an insertion method known a curable liquid in a solid, which ver a device known as a "cartridge system" turns. Closed bottles with a little län provided outlet tubes and in the filled state in the Hole inserted. The bottles just give the liquid in the amount that is absorbed by the masonry. To The outlet tube is the entry of the liquid into the bore Chen completely filled with liquid so that no more air can get into the bottle. Accordingly, no liquid can run after. After the liquid seeps away or is absorbed  air returns through the masonry - through the outlet tube through - into the bottle, so that again liquid from the bottle into the hole. Hence an all gradual saturation of the masonry possible. Here can be a sufficient and effective at the same time Realize the same dosage of the liquid.

Now point those with a capillary water barrier Solids, especially masonry or concrete walls, often very significant voids, gaps, cracks and open joints, so that according to the known methods by means of the known Fixtures placed in the well all if in a very small amount soaked up by the masonry can and mostly into the cavities - uncontrolled - runs in. A distribution of the fluid within the Boh and a capillary flow from there into the the area of the masonry lying around the hole is therefore not more guaranteed. Rather, the relatively expensive curable Liquid wasted.

The previously mentioned problem has thus been attempted solve that - after finding this within the Masonry "leak" - the hole with a like which has poured out absorbent filler, at least partly also spreads in the cavities. After curing can then in turn drill a hole so that the pourable or pourable hardenable liquid into a kind of inlet is felt. In practice, however, this is problematic table, as the procedural steps - drilling a hole, off pour the bore through a curable and cured one Condition absorbent material, new drilling and on closing the liquid into the second hole - is extremely complex and therefore expensive. This is ins especially clear when you keep in mind that the  Depending on the type of damage, holes are only a few centimeters apart which is spaced in a horizontal line in the often meter long masonry must be installed. Furthermore, through that Do not fill a curable solid into the hole ensures that a cavity within the masonry too is actually completed. Hence, the more possible wise not completely filled cavity within the wall works always an interruption of the horizontal capillary-what lock, which increases the effectiveness of the horizontal capillary Overall water barrier is questioned.

The present invention is therefore based on the object an apparatus and a method for introducing one from curable liquid, especially a capillary water lock, in an absorbent solid, preferably in a Masonry, in concrete or in wood, to indicate with or after which can be hardened into cavities, cracks, Solids with gaps and large pores to form egg a horizontal capillary water barrier with simple means let bring in.

The inventive device for introducing a hardens liquid, especially a capillary water barrier, in an absorbent solid, preferably in masonry, in Concrete or in wood, solves the above task through the Features of claim 1. Then the ste in question Device formed such that the Auslaufeinrich a suction at least partially filling the hole capable source body.

According to the invention it has been recognized that the inside of a Masonry cavities, cracks or the like, a sub Refraction of the liquid caused by capillary forces cause line. In another according to the invention  Step has been recognized that it is not necessary these cavities to the capillary line with an absorbent Fill in material. Rather, according to the invention the cavities or cracks inside the masonry bridged by an absorbent swelling body, which at Soak up the curable liquid on the inner wall the hole presses and at least slightly into cavities, cracks or the like. Hence they are the capillary line effectively bridging interrupting cavities or cracks, so that the curable liquid is in the direction of flow seen spreading just as well after a cavity or crack can be like before. This is due to the fact that the as Part of the outlet device serving swell the rivers overall transported through the bore and due to the all-round contact with the masonry Liquid into the masonry thanks to capillary forces is sucked in.

Regarding a particularly simple insertion of the swelling body in the hole or in the masonry or in another absorbent solids, it is of particular advantage if the source body is designed as an approximately round rod. Here the bore should be matched to the rod diameter, so that an unimpeded insertion of the rod or swelling body into the hole is possible. In other words, the source body inserted into the hole similar to a bracket. Provided it is necessary to remove the swelling body after the capillary To remove the water barrier again, this could be drilled out and the hole filled with mortar, for example, or closed will be. However, it would also be conceivable to include the swelling body to surround a preferably elastic network, which the Overall encloses the swelling body and out of the hole protrudes. By means of this network, the source body could move to one bring the liquid out of the hole again - by force -  be pulled out. The net itself could be silicone coated be so that a sliding between the source body and In nenwandung the bore is ensured, which the out pulling the source body is favored.

As previously mentioned, the swelling body should be on the Boh tion or vice versa. To do this, the swelling body per be dimensioned such that it is dry in the Bore form-fitting or at most with little play, d. H. almost form-fitting, filled and at least for the most part stretched into the hole. This is necessary to the extent as usually cannot be recognized from outside the borehole, where there are cracks or voids. With other wor the swelling body should cover almost the entire Boh Extend through or just as far in the hole ver dwindle, that later explained storage container or off running devices on the bore or the source body are feasible.

The source body itself must be made of an absorbent material stand, which swells when a liquid is sucked up. Pressed cellulose material is particularly suitable for this, which is here in a particularly advantageous manner Recycled cellulose material can act.

To the swelling body effective even with little play in the Boh Being able to spend it can prevent it from kinking a stiffening inner soul of the source body can be provided. This inner core is advantageously plastically bendable, stiff in the axial direction. With the inner soul can it is a metal or plastic wire.

The previously mentioned storage container is ready for use position of the curable liquid. This liquid, e.g.  CRISIN 76 (registered trademark of Köster Bauche mie GmbH), works due to its composition or inventory parts resinifying and not silicifying and thus creates one permanent and elastic capillary water barrier, that is rotten. The front that absorbs this liquid storage containers could be as part of a particularly simple Design of the device according to the invention as a bottle be executed. One bottle could be inserted per hole be set. The free or open end of the bottle neck could restrict or meter the flow of liquid an outlet nozzle, a flow limiter or a dosing unit have direction.

With regard to a particularly simple attachment of the bottle in the area of the bore the neck of the bottle could be so dimensio be kidney that he with his open end in the bore at least partially fits or is insertable to the Contact source body for capillary fluid line. As part of a particularly safe attachment of the bottle the bottle neck could be screwed into the hole and have a kind of self-tapping external thread, so that in the masonry - apart from the hole - no special ones Precautions are to be taken.

In a further embodiment, the source rod could with its end facing the bottle at least partially in protrude the bottle and through the bottle neck or a passageway closure. As a result, the bottle would be excluded by the source body itself held in place half of the hole. A stiffening inside soul of the source rod according to the previous statements would be of particular advantage here.  

As part of a further advantageous embodiment or Aus In the embodiment, the outlet device could be an open one End plugged or screwed on at the end of the bottle neck have running tubes. The outlet tube could be like this be dimensioned so that it with the source body at the Storage tank facing end towards the capillary Liquid line is contactable.

For safe contacting of the outlet tube, the Swelling body at its end facing the reservoir Bore, recess or the like. For inserting the outlet tube chens have, so that the outlet tube in the working position tion protrudes at least slightly into the swelling body. A Such a configuration of the swelling body has the great advantage that even with axial displacement of the swelling body or the Storage container a safe contact and thus a si Chere liquid line is always guaranteed.

As part of an alternative embodiment of the The device could be the preferred device central tank. The outlet facility would then one leading out of the tank to the swelling body, ka include pillar fluid line. This would have been the whole thing special advantage that from a single reservoir from, namely from the tank, numerous holes or swell bodies via an appropriate outlet device with liquid can be supplied. In this respect, none would be special for each hole Required containers such as bottles or the like. On central refilling of the tank would also be guaranteed.

As part of a central supply of liquid from one The source body could be an integral part of the liquid management. It would be an advantage if the swelling body per and / or the liquid line at least largely pla  would be bendable. The capillary fluid line tion could be in the context of a particularly advantageous embodiment tion carried out in the sense of an absorbent wick or the like be so that the line of liquid from the tank into the bore due to capillary forces.

After all, it would be a very simple one Design of the device according to the invention possible Storage container as a bulk container, preferably as a watering can, Measuring cup or the like. The source body would then be that only element of the outlet device, the source body would have to be sunk in the hole, so that from the bulk container liquid can be poured out into the bore. As well it would be conceivable to rely on the usually obliquely downward hole - after inserting the swelling body - a trich ter put in the liquid from the bulk container is poured out. The equipment costs would also be relevant in this respect relatively low.

The inventive method for introducing a curable ren liquid, in particular a capillary water barrier, in an absorbent solid, preferably in masonry, in Concrete or in wood - using one previously discussed Device - solves the above task through the features of claim 21. Thereafter includes the invention The following process steps:

First, a hole is drilled in the solid, whereby this usually slants downward to next to the capillary forces also act on a liquid To use gravity. Then the source body is in the hole spent. Between the source body and a die Liquid-containing storage container becomes a Flow connection or capillary line established. Rivers  liquid is removed from the storage container via an outlet device device and the swelling body in the solid or in the wall brought in. When the liquid flows into the spring body swells up due to the sucked-in liquid and presses against the inner wall of the bore. Cavities or Cracks or the like are caused by the swelling body in the sense of a Ka bridged pillar line. There is a capillary inside the hole Clear liquid line through or in capillary gaps and pores of the solid.

The method according to the invention could avoid sub Refractions of the capillary flow or to avoid ver darings are supplemented by the fact that after the introduction of the Drilling into the solid and before introducing the liquid the hole is cleaned with compressed air and / or water. A perfect capillary flow into the masonry would be there favored by quite considerably.

It would also be conceivable to place the swelling body in front of the liquid swelling, d. H. before introducing the liquid, by means of a preferably elongated tool, in particular mechanically by driving in a mandrel or the like "sources". This would be before the liquid is introduced ensures that the swelling body on all sides on the inner wall the bore and a capillary line in the Solid body is guaranteed right from the start.

Finally, the method according to the invention can thereby favor that the establishment of a flow connection between inserting the swelling body and the reservoir a bottle serving as a storage container or one on the Bottle neck attached or screwed on outlet tube chens in the bore and the contacting of the free end of the Bottle neck or the discharge tube with the swelling body  includes, the outlet tube also in the source body can protrude.

There are now several ways to teach the present the present invention in an advantageous manner and white to train. On the one hand, reference is made to the claims 1 and 21 subordinate claims, on the other hand to the successor lowing explanation of two embodiments of the fiction to refer to the device based on the drawing.
