Definitions
- the invention relates to a method for renovating damp masonry by creating a moisture barrier in the masonry, which consists of a hydrophobic mass, in particular paraffin, which is introduced into the blind holes formed in the masonry and heated there.
- the invention relates to a device for performing this method.
- a generic renovation method is known for example from the patent specification DD 280 346 AI.
- a wax granulate is filled into the boreholes and melted over a rod-shaped heater, the borehole being sealed off from the outside.
- the sealing is intended to increase the pressure in the melted wax and thus to achieve an improved penetration process for the masonry.
- the invention has for its object to provide a method for renovating damp masonry, in which the blind hole in the masonry can be filled with paraffin without liquid paraffin can escape on the outside of the wall.
- hydrophobic mass is liquidly removed from a storage container working according to the vacuum principle by means of a feed line which can be inserted into the blind hole.
- the melted paraffin is therefore in a storage container which is pressure-tight and from which the melted paraffin can flow out of the storage container by means of a supply line according to the vacuum principle.
- the term "vacuum principle" will be explained in the following.
- the storage container which contains liquid paraffin, is in the position of use above a borehole that is to be filled with liquid paraffin. Now the paraffin is introduced into the blind hole through the feed line inserted into the blind hole to a level at which the open end of the feed line is reached by the paraffin mirror in the obliquely downwardly inclined blind hole and thus prevents air from being drawn against the outflowing paraffin can flow into the reservoir.
- the moisture evaporates at the phase boundary of liquid paraffin water, so that the moisture is present in the pores of the wall in a gaseous and thus compressible state. Due to the capillary forces of the masonry, the liquid paraffin penetrates into the vicinity of the blind hole, displacing the moisture, and finally fills the entire masonry at a blind hole height with a paraffin barrier.
- the evaporation of moisture removes a relatively large amount of heat from the liquid paraffin in the blind hole area due to the phase change, so that the paraffin would solidify relatively quickly in the blind hole without additional heating or a complete penetration of the masonry would not be possible.
- the heating introduced into the borehole prevents premature solidification of the paraffin.
- the storage container is preferably heated so that the paraffin running out into the borehole already has a comparatively thin consistency and cannot solidify even during a long treatment period. Due to the heating introduced into the borehole, there is also no risk that the heating element will overheat, since the liquid paraffin provides good heat transfer between the heating and the masonry.
- the heating element used for heating the paraffin in the borehole is preferably rod-shaped and is used at the same time for heating the storage container.
- the heating element can, for example, be guided pressure-tight directly through the interior of the storage container, on the other hand, a heating channel in the storage container is also possible, which is penetrated by the rod-shaped heating element.
- the feed line which is inserted into the blind hole, from a good heat-conducting material such as. B. copper.
- the supply line itself serves as a heating element, which enables a sufficiently large heat transfer from the heated paraffin in the storage container to the paraffin in the blind hole.
- the lower end of the feed line can be perforated, so that large heat transfer surfaces are available.
- a paraffin level occurs in the blind hole, which extends to the upper end of the perforated area.
- a device according to the invention for carrying out the method results directly from the description of the method according to the invention.
- the one based on the vacuum principle Working storage container which is arranged in the position of use above the blind hole, preferably has an airtightly closable upper filling opening through which liquid or solid paraffin can be filled, for example. After the filling process has ended, the filling opening is closed in an airtight manner so that outside air can no longer get into the interior of the container through the filling opening.
- the lower feed line preferably also has a shut-off element, so that liquid paraffin can no longer escape from the storage container when the injection process has ended and the supply container with its lower feed line is removed from the blind hole.
- a rod-shaped heating element For heating the storage container or the paraffin in the blind hole, a rod-shaped heating element is preferably used, which passes through the storage container and dips with its lower end into the blind hole, which is partially filled with paraffin.
- the storage container preferably has a filling level measuring device which indicates the respective filling level in the interior of the container. If the fill level is too low, this fill level measuring device can automatically switch off the heating element or be coupled to a refill container which automatically refills the reservoir when the fill level is too low.
- a circuit can be provided by means of which the shut-off element in the supply line is closed when the storage container is refilled and only opens again when a sufficient fill level is measured by the fill level measuring device.
- FIG. 1 shows a schematic section through a storage container and masonry with a blind hole, a heating rod being used to heat the storage container and the paraffin in the blind hole, and
- FIG. 2 shows a section through a storage container and masonry with a blind hole, the storage container and the paraffin in the blind hole being heated by separate heating elements.
- the reservoir 1 shown in FIG. 1 is filled with liquid paraffin 2 and is heated via a heating element 3, which passes through a bore 4 of the reservoir 1 with its upper part 5, so that the paraffin 2 does not penetrate inside the reservoir 1 can freeze.
- Granular or liquid paraffin 2 can be refilled through an upper filler opening 6, which can be closed airtight with the aid of a locking member 7.
- a feed line 8 is arranged, which has an outlet opening 10 at its lower end 9 and can be inserted into a blind hole 11 which is introduced obliquely downwards into a masonry 12 in need of renovation.
- a further blocking member 13 is provided, which is open during operation so that liquid paraffin 2 can escape into the blind hole 11.
- liquid paraffin 2 Due to the storage container 1 working according to the vacuum principle, however, liquid paraffin 2 only runs as long into the blind hole 11 until a paraffin mirror 14 is reached, through which the outlet opening 10 is closed. Because of the negative pressure building up in the upper region 15 of the storage container 1, no liquid paraffin 2 can flow into the blind hole 11 until the paraffin mirror 14 sinks below the outlet opening 10 and air can thus penetrate into the storage container 1.
- the lower end 16 of the heating rod 3 is inserted into the blind hole 11 and heats the paraffin therein, so that it can compensate for the heat losses due to moisture evaporation taking place in the blind hole environment and intensive penetration of the masonry 12 is possible with paraffin.
- a separate heating element 17 is used to heat the paraffin in the blind hole 11, while a separate floor heating 18 is provided for heating the storage container 1.
