Definitions

  • the invention relates to a method according to the preamble of claim 1.
  • the cause of damage to structures is mostly due to the fact that, due to the cement content in the facade plaster, the breathability (ventilation) necessary for the removal of the moisture contained in the masonry or the moisture entering it from the soil is severely impaired. There is therefore damage to the saltpetre, which can be seen from the outside by destroying the paint and peeling off the plaster. Since the mere renewal of the plaster (cf. the magazine “Bauwelt", 1972 H. 19, pp.761, 762 and 764) does not remedy the actual cause of the damage, a permanent renovation cannot be achieved with such a measure; this is all the less because the nitrate infestation of the masonry that has already occurred is not taken into account. Since the saltpetre already present in the masonry soon migrates back into the plaster layer, damage to the facade occurs again after a relatively short time.
  • the invention is based on the object
  • the method according to the invention is used with particular advantage in the renovation of the facades of historically important buildings.
  • plate-shaped components made of hollow-brick material can be used. They can be obtained by cutting approximately 3-4 cm thick slices from such bricks.
  • this treatment not needing to extend over the entire thickness of the bricks, but limited to an area adjacent to the ventilation cavity can be.
  • the elements are anchored in the masonry, spacers being arranged between the elements and the masonry. Their thickness is expediently chosen so that the cavity has at least a depth of about 1 cm.
  • the veneer elements can be anchored by means of dowels.
  • the facade plaster which according to the invention consists of lime mortar, i.e. a cement-free binder, that the plaster layer is also ventilated on the masonry side
  • the invention provides that the recesses in the plate-shaped components within the plaster-side openings provided plaster base is permeable to air. This requirement is met, for example, by a porous, coarse-grained lime mortar. This can be worked into the openings in a still workable state, ie before setting, without filling them over their entire length in the direction of the ventilation cavity.
  • the mortar can be removed with a crossbar.
  • the facade plaster made of lime mortar is then applied to the veneer, which is expediently only smoothed, but not treated with felt.
  • the thickness of the plaster layer can be about 1 - 1 1/2 cm.
  • One third of the mortar for the fine plaster layer of the facade can consist of lime soaked in for a longer period and two thirds of pure fine-grained river sand. It can be colored with oxide pigments or a (commercially available) mineral structural plaster can be applied.
  • the grout between the masonry bricks should advantageously be scraped out to a depth of about 1 cm.
  • the efflorescence on the masonry is expediently treated with an anti-salting agent before the veneer is built up. It is important to ensure that the treatment agent is then completely removed by washing the masonry thoroughly.
  • the open connection provided on the underside of the veneer between the outside air and the cavity between the veneer and the brick wall can be created in such a way that the bottom layer of the veneer elements is supported on a suitable commercially available rail, preferably made of aluminum, and this by individual support elements is kept at a distance from a superior base or the like.
  • the support elements suitably consist of ceramic plates. Their thickness can be approximately 1 1/2 - 2 cm, which increases the height of the between the rail and the base created slot through which the outside air can penetrate into the cavity between the veneer and the brick wall and can provide the ventilation necessary for the removal of moisture.
  • the air entering the cavity between the facing and the masonry from below is discharged upwards, an open connection between the outside air and the cavity also being provided on the top of the facing to maintain the air circulation.
  • the upper opening can be closed at a later time if it can be seen that no more moisture rises from the foundation into the masonry and causes the formation of wall saltpetre.
  • the veneer erected in the course of the renovation measures according to the invention need not extend over the entire height of an outer wall of the building. For cost reasons, it can be useful to limit the veneer to the area that is visibly damaged by moisture rising from the foundation
  • the (old) wall to be renovated by the method according to the invention consists of the bricks 1, which are laid by means of the grout 2.
  • the cement-containing plaster layer is first removed from the side of the (old) wall facing the facade. On this side, as can be seen from the drawing, the grout 2 is removed over a certain depth (cf. a).
  • the foundation for the brick wall is formed by an old part 14 'and a new part 14 ".
  • the latter preferably consists of hard-fired perforated bricks, which are introduced under the brick wall as part of the renovation measure.
  • the aluminum foundation 14' is first laid from the facade via a certain depth, expediently cut out according to the height of the commercially available hard fired brick, in order to make room for their subsequent installation.
  • the horizontal, continuously formed recesses 14 '"present in the new part 14" of the foundation can be used in conjunction with a later described one Base 10 and the cavity created between this and the foundation, the foundation 14 'are effectively ventilated and the moisture present therein is already discharged to the outside before it reaches the brick wall.
  • the facing built at a distance from the brick wall consists of plate-shaped components 4, which also have horizontal, continuous recesses 4 'and suitably consist of hollow-brick material. You can use the commercially available hollow brick (formats: 24 x 12 cm; 24 x 17 cm; 24 x 30 cm).
  • the veneer creates a ventilation cavity 5 between this and the existing brick wall.
  • the width of the cavity is determined by the thickness of the spacers 6, which are expediently disc-shaped and are provided between the facing and the brick wall, through which (plastic) dowels 7 pass, by means of which the components 4 are fastened to the brick wall.
  • the facing rests on a rail 8 with a U-profile.
  • the front bend 8 'of this rail is embedded in the lime mortar plaster layer 12 applied to the components 4, before the application of which an air-permeable plaster base material 3 was introduced into the opening of the recesses 4' on the plaster side.
  • the rear bend 8 "engages behind the lowest position of the components 4.
  • the fixation of the lower components 4 which can be achieved thereby is further promoted by the fact that 8" mortar is introduced between them and the bend. In this way, existing inaccuracies can be compensated for. In this context, it proves to be useful if the bend 8 "is provided with recesses in which the mortar can settle.
  • the rail 8 is supported on individual support elements 9, suitably made of ceramic plates, which can have a length of approximately 5 cm and a width of approximately 3-4 cm and a thickness of approximately 2 cm. They are at a distance of for example 30 cm on the preset during the remedial measures socket 10 is arranged, so that between the support elements 9 through openings 1 1 (see. Fig. 2) are formed for the inflowing of the facade forth in the cavity 5 air.
  • the base 1 0 can be formed from sandstone slabs with a thickness of, for example, 3 cm, which are naturally permeable to air, but to promote particularly intensive ventilation, as shown in FIG. 1, can also be provided with horizontal, continuous recesses 10 ' can.
  • the front of the sandstone base simultaneously protects the masonry against moisture and the foundation against the ingress of litter.
  • the dowels 7 are mounted in the joints between plate-shaped components, it being possible for a plurality of components 4 to be fixed at one time by means of retaining disks 13 clamped between the dowel head and the elements.
  • the measures according to the invention provide such effective ventilation of the brick wall that moisture no longer rise from the foundation into the wall and can cause the formation of damaging wall saltpetre there.
  • the ventilation is illustrated in the figures by the arrows.
