Definitions
- the present invention relates to a method for preparing and renovateding ancient walls, in particular made of stones, bricks, mortar and the like, and an apparatus for carrying out the method.
- a pressing method is known from the prior art, an ancient wall, which may be several centuries old, being cleaned first.
- the cleaning includes cleaning the surface, for example by means of steam jets, water steam jets or sandblasting.
- the repairing of joints as well as bricking up and subsequent plastering then follow.
- Such cleaning and repair of an ancient wall only affects the surface and not the wall itself.
- a plurality of bores are drilled into the wall to be renovated, at least 4 first surface.
- the holes have a diameter of approx. 2-5 cm and are approximately 15 cm deep in the wall.
- be pressure hoses connected to such bores, and the wall to be renovated is mortared in by means of high pressure.
- a mixture of cement, mortar or the like suspension enters cavities, fills them, and hardens there.
- the pressure hoses are then removed again and the holes are plastered.
- a disadvantage of such a method for preparing and renovating walls is that the original composition of the wall is changed.
- only porous components of the conventional mortar and the other components of the wall, such as stones, bricks or the like, are enclosed and held together in the suspension.
- the original mortar structure and in particular the original structure of the wall is therefore destroyed.
- suspensions which also contain cement-like components, there are different materials in the wall with different hardness.
- the original ancient mortar is not soaked by the suspension, although such a wall is pressurized, for example, with 15 bar pressure, since the original mortar withstands a pressure of approx. 0.9 to 1.2 N / mm ⁇ . This means that the original mortar cannot be soaked and fixed with this method.
- the object of the present invention is therefore to create a method and a device, with which the above-mentioned disadvantages can be eliminated in a simple and inexpensive manner. Furthermore, the original structure of an ancient wall should not be damaged and preserved. This should also be possible when erecting a lowered or sloping wall.
- the solution to this problem is that the wall is laterally sealed and water is applied from above until the mortar is at least partially softened, a binder then being applied to the wall, in particular to a wall crown.
- the wall can be moved back to its original vertical position by applying pressure to the corresponding formwork elements.
- a foundation is then, if necessary. created to fix the wall.
- the wall and in particular its components such as stones, mortar are not changed or even damaged.
- water is briefly flowed through the wall again in the manner described above.
- a binder from above in particular poured from the top of a wall, with sealed rare walls, through the wall.
- the binding force which in particular consists of conventional lime materials such as white lime hydrate, trass lime or the like, is introduced into the wall by the force of gravity and in particular the capillary action.
- the capillary action also soaks through the now softened and possibly elastic mortar or penetrates it with the binder.
- the wall may remain in the formwork to harden and then be removed.
- the mortar By adding lime or lime derivatives, the mortar regains its original shape. Giants that were originally present in the porous mortar bind on the one hand through watering and on the other hand through the binding agent to a solid structure and unity. Thus all parts of the wall are firmly integrated again. This wall can last for many more centuries without further damage. In addition, the original and ancient condition has been restored without adding new or different materials to the wall.
- the wall is subjected to pressure from the side by means of the appropriate casing, and in particular by the buffer element, without causing damage or other impairments to wall components.
- the buffer element yields in the event of unevenness and at the same time prints the film, which is designed as a sealing element, against the lateral masonry. A seal is created so that the liquid, water or binding agent must flow through the wall directly from above and cannot escape laterally. If the wall is smooth and plastered, the buffer element may be omitted. This is also intended to be encompassed by the present inventive concept.
- Figure 1 shows a cross section through an inventive device for preparing and renovating an ancient wall in the use position
- Figure 2 shows a further cross section through a device for the preparation and renovation of walls in a further position of use.
- a device R according to the invention has a formwork 1.1, 1.2, which rests laterally on a wall 2.
- the formwork 1.1, 1.2 is held against the wall 2 by means of support elements 3.1, 3.2.
- the support elements 3.1, 3.2 are, as indicated in Doppelpfeil ⁇ chtung, designed to be adjustable in length. This can be done mechanically, for example by means of threads, or pneumatically.
- the support elements 3.1, 3.2 are supported on a bottom surface 4.
- the special feature of the present invention is that between the cladding 1.1, 1.2, a sealing element 5.1, 5.2 bears on both sides of the wall and a buffer element 6.1, 6.2 is then arranged therebetween.
- the sealing element 5.1, 5.2 consists essentially of a water-impermeable film, which is preferably elastic.
- the adjoining buffer element 6.1, 6.2 for example, as a dam mat, is very soft and also elastic. This serves to compensate for unevenness in the wall 2 when pressure is applied to the formwork 1.1, 1.2 against the wall 2. In this way, the sealing element 5.1 or 5.2 rests directly on the side of the wall 2 and forms a lateral support and seal. In addition, it is ensured that protruding components of the wall 2 are not damaged.
- a lateral seal is produced by such an application of a device R according to the invention.
- the sealing element 5.1, 5.2 can be dispensed with and only the buffer element 6.1, 6.2 is used for sealing and trimming. This is then optionally provided with a water-impermeable surface facing the wall. If such a seal is made, the wall 2 is loaded with water, drenched and watered from above onto a wall crown 7.
- This irrigation process should preferably last for a longer period of time, so that the water can flow from top to bottom through the individual components of the wall 2, such as stones 8 and in particular the mortar 9. This is indicated in FIG. 1 with the direction of the arrow shown.
- the stones 8 and in particular the mortar 9 are wetted by water. Due to the capillary action and in particular the gradient, the brittle and dried mortar 9 is soaked with water when water is applied. After a certain exposure time, it becomes soft and elastic.
- a binder in particular of white lime hydrate, hydrate lime, trass lime or the like, is applied to the wall crown 7. This has the effect that the binder binds to the mortar in the wall 2 through the capillary action and in this way restores the strength and durability of the wall 2.
- These binders were also used earlier in the manufacture of such a wall 2. In this way, an ancient historical wall 2 is prepared and restored without the original components of the wall 2 being changed, for example by additives such as cement.
- the cladding 1.1, 1.2 and in particular the sealing elements 5.1, 5.2 and the buffer elements 6.1, 6.2 can be removed from the wall. This wall 2 is then stable again for many decades, the individual stones 8 and other components being firmly integrated in the conventional mortar 8.
- the device R is shown in a different position of use.
- the device R and in particular its casing 1.1, 1.2 is placed against an inclined wall 2.1.
- the sealing element 5.1, 5.2 and the buffer element 6.1, 6.2 are arranged in between, as described above. So that such an inclined wall 2.1 can be erected back into its vertical position, the formwork 1.1, 1.2 is laterally applied laterally with the sealing elements 5.1, 5.2 and buffer elements 6.1, 6.2 which have been arranged in the meantime before erection.
- pressure to the wall 2.1 there is a lateral seal, as has already been described above.
- the wall 2.1 can be moved out or by applying pressure to the formwork 1.2 simultaneous retraction of the support element 3.1 or the formwork 1.1 m the vertical.
- the structure of the wall 2.1 is not damaged due to the elastic and softened mortar 9.
- a foundation (not shown here) is poured in order to fix the wall 2.1 vertically thereon.
- the wall 2.1 is briefly exposed to water from the wall crown 7. All capillaries of wall 2.1 or mortar 9 are filled with water again.
- the binder is added in order to firmly bind all components of the wall, in particular the stones 8, into the mortar 9 and to consolidate it.
- the wall can then be removed. It should also be considered here to provide the end faces of the wall with appropriate cladding and with sealing elements and / or buffer elements.
- the present invention provides a method and a device with which an ancient historical wall 2, 2.1 can be aligned and renovated in the simplest and very cost-effective manner.
- conventional materials are used only in the present invention, which were used in the construction of such an ancient wall from earlier.
- the structural substance of the ancient wall 2, 2.1 is not changed.
