Definitions

  • the invention relates to a wall arrangement of the type specified in the preamble of claim 1.
  • the so-called perforated facade formed in this way can be used, for example, as a privacy screen, for example in front of windows, or as a fence.
  • Such perforated facades have a purely architectural, optical function.
  • the bricks of the wall usually overlap in the vertical direction so that vertical forces are absorbed by the bricks themselves. So that the wall is sufficiently stable, a stiffening arrangement is usually provided on the wall, which absorbs forces acting perpendicularly on the wall. Reinforcing bars, for example, are known as such a stiffening arrangement, which protrude perpendicularly through the bricks. It is also known to provide a stiffening arrangement at the back of the wall to support the bricks.
  • the object of the invention is to create a wall arrangement of the generic type that is easy to produce and has an attractive appearance.
  • reinforcing rods running vertically in the bricks are disadvantageous in the manufacture of high walls in particular, since the bricks have to be threaded onto the reinforcing rods from above.
  • a stiffening arrangement arranged on a rear side of the wall is visible on the rear side of the wall and is therefore associated with optical disadvantages.
  • the stiffening arrangement extends at least in the perforated area of the wall completely between the opposite flat sides of the wall formed by the bricks. Because the stiffening arrangement does not protrude beyond the flat sides of the wall in the perforated area of the wall, the visual impression of the wall is not disturbed. In order to nevertheless achieve sufficient stability of the wall in the direction perpendicular to the plane of the wall, it is provided that the stiffening arrangement comprises at least one sheet metal strip which is arranged in the perforated area of the wall between two layers of bricks lying one on top of the other. The metal strip has a high moment of inertia in the direction perpendicular to the wall and can thus stabilize the wall well even if the metal strip is relatively thin.
  • the metal strip Due to the fact that the metal strip is arranged between two layers of bricks lying one on top of the other, the metal strip is only visible in the area of the openings. This achieves an almost invisible stiffening of the wall and creates an attractive visual impression.
  • Such a metal strip is easy to produce and can be easily inserted into the mortar layer between the superimposed layers of bricks during the manufacture of the wall. This also makes it easy to manufacture the wall.
  • the sheet metal strip runs between the superimposed layers of bricks, ie usually horizontally.
  • the metal strip preferably extends over the entire width of the perforated area.
  • the bricks In order to be able to absorb forces perpendicular to the plane of the wall, it must be ensured that the bricks are firmly connected to the sheet metal strips. This can be done in a simple way by positively connecting the sheet metal strips to the bricks.
  • a particularly simple design results when at least one peg-shaped positioning element is fixed to the sheet metal strip for at least one, in particular for each brick, and extends into a depression in the brick extends and thereby secures the brick in a form-fitting manner in the direction perpendicular to the wall.
  • the peg-shaped positioning element simultaneously provides a grid for the arrangement of the bricks in a layer. As a result, the bricks can be positioned in a simple manner during the manufacture of the wall. This significantly simplifies the manufacture of the wall.
  • At least one positioning element is a rivet. This results in a simple, inexpensive and easy-to-manufacture construction of the metal strip.
  • at least one positioning element is a bolt.
  • the bolt is fixed to the metal strip by forming.
  • at least one retaining ring can be provided for fixing the bolt to the metal strip.
  • the retaining ring can be a metal ring.
  • the retaining ring is made of plastic.
  • the retaining ring can be formed by a seal, for example.
  • At least one positioning element is formed by a bent section of the metal strip.
  • the section of the sheet metal strip can be pre-punched during production of the sheet metal strip and then bent out of the plane of the sheet metal strip. As a result, no additional components are required for the at least one positioning element.
  • the opening in the metal strip that occurs when the bent section is bent improves the anchoring of the metal strip in the respective layer of mortar at the same time.
  • the stiffening arrangement advantageously has means for fixing the metal strips to a supporting structure.
  • the stiffening structure advantageously has at least one support which is arranged outside the wall and on which at least one metal strip is fixed.
  • the support is arranged on the side of the perforated area of the wall, so that the support does not disturb the visual impression of the wall and in particular the visual impression of the perforated area.
  • the support can be made of metal, for example.
  • the support is a metal support.
  • the supporting structure can also be a supporting wall or the like running outside of the perforated area.
  • the sheet metal strip is fixed outside the perforated area in the mortar between layers of bricks lying one on top of the other.
  • the wall advantageously has sufficient stability to absorb the loads acting perpendicularly on the wall. This area can therefore be used to fix the metal strips and to absorb the loads from the perforated area that are absorbed via the metal strips.
  • a simple design results when the sheet metal strip has at least one opening outside of the perforated area, in which mortar is arranged.
  • the breakthrough can be formed, for example, as a punched through opening in the sheet metal strip.
  • Another way of fixing the sheet metal strip between the layers of bricks lying one on top of the other for example a form-fit fixing, can also be advantageous.
  • the metal strip is designed as a continuous, flat flat material in at least one section delimiting an opening, advantageously in all sections delimiting an opening. Accordingly, the metal strip has no openings, depressions, bent areas or similar structures in the at least one section delimiting the opening. Advantageously, no positioning element is provided in this section either. This achieves a visually appealing delimitation of the at least one opening.
  • the distance between adjacent bricks is at least 20%, in particular at least 30%, of the length of a brick.
  • a large distance between adjacent bricks inevitably leads to a small overlap of the bricks. This reduces the stability of the breached area of the wall. Due to the stiffening arrangement provided, very large distances can be realized between adjacent bricks and still sufficient stability of the perforated area of the wall can be achieved.
  • FIG. 1 shows a wall arrangement 1 schematically and in perspective, which comprises a wall 2 and a stiffening arrangement 8 for supporting the wall 2.
  • FIG. The stiffening arrangement 8 is in 1 barely visible and in perspective as a stiffener assembly 8 in 2 shown.
  • the wall 2 is made up of bricks 3 between which layers of mortar 13 run to connect the bricks 3 . In 1 only a portion of a horizontal layer of mortar 13 is shown schematically. Corresponding mortar layers 13 (not shown) are arranged in the usual way between the other bricks 3 .
  • the bricks 3 are arranged in layers 4 of bricks 3 one on top of the other.
  • the bricks 3 are offset in the layers 4 lying on top of one another and arranged in an overlapping manner.
  • the wall 2 has a perforated area 5 in which openings 10 are formed.
  • the openings 10 are formed by a distance a between adjacent bricks 3 .
  • the wall 3 is open in the area of the openings 10 so that one can look through the wall 3 .
  • Such perforated areas 5 are also referred to as perforated facades.
  • the openings 10 are arranged in a regular pattern in the perforated area 5 .
  • a different arrangement of the openings 10 can also be provided. Provision can also be made for openings 10 to extend over more than one layer 4 of bricks 3 .
  • the perforated area 5 has a width c.
  • the width c is measured parallel to the plane of the wall and between the outermost edges of the openings 10 on the outside.
  • the bricks 3 have a length b measured parallel to the distance a.
  • the distance a is advantageously at least 20%, in particular at least 30%, of the length b of the bricks 3.
  • the bricks 3 overlap only slightly in the perforated area 5. This results in a reduced stability of the wall 2 in the perforated area 5.
  • Forces acting vertically downwards are intercepted in the perforated area 5 in the usual manner by the bricks 3 arranged one above the other.
  • the in 2 illustrated stiffening structure 8 is provided.
  • the stiffening structure 8 includes how 2 shows several metal strips 9 arranged one above the other.
  • the metal strips 9 have a middle section 23 which can be arranged in a perforated area 5 .
  • a first fastening section 20 adjoins the middle section 23 at one end.
  • a second attachment section 21 connects to the other end of the central section 23 .
  • the metal strip 9 is fixed to a supporting structure.
  • the stiffening arrangement 8 in the perforated area 5 extends exclusively into the area between the flat sides 6 and 7 of the wall 2.
  • a first flat side 6 is the outside of the wall 2 and an opposite, second flat side 7 of the wall 2 the inner side.
  • the openings 10 each extend continuously between the flat sides 6 and 7.
  • the bricks 3 have a thickness e measured perpendicularly to the plane of the wall 2, which in 1 is drawn.
  • the metal strips 9 have a width f measured in the same direction, such as 2 shows.
  • the width f is at most as large as the thickness e.
  • the width f is advantageously smaller than the thickness e.
  • the width f is advantageously 60% to 90% of the thickness e. This achieves sufficient rigidity of the metal strip 9 in the direction perpendicular to the wall 2, and it is possible to cover the metal strip 9 with mortar on the longitudinal sides of the metal strip 9, so that the metal strip 9 is not visible between bricks 3 lying on top of one another.
  • the thickness e of the metal strip 9 ( 2 ) is advantageously not greater, in particular less than the distance h between superimposed layers 4 of bricks 3 ( 1 ).
  • the distance h is advantageously measured outside of the perforated area 5 . As a result, a uniform joint height of the wall 2 can be achieved.
  • the flat sides 6 and 7 are each formed by the outer areas of the bricks. The flat sides 6 and 7 therefore delimit a space in which all bricks 3 of the perforated area 5 are completely arranged.
  • the stiffening arrangement 8 extends completely between the flat sides 6 and 7 and does not protrude beyond them. As a result, the stiffening arrangement 8 in the perforated area 5 is only slightly visible from both flat sides 6, 7 of the wall 2.
  • the metal strips 9 run between superimposed layers 4 of bricks 3. Only in the area of openings 10 are the metal strips 9 on the top or bottom of an opening 10 visible. Depending on the design, the end faces of the metal strips 9 can also be visible between superimposed layers 4 of bricks 3 .
  • a metal strip 9 is not arranged between each superimposed layer 4, but only every two layers. The number of metal strips 9 can be selected in a suitable manner depending on the forces to be absorbed and acting perpendicularly on the wall 2 .
  • the bricks 3 have a multiplicity of indentations 12 .
  • the bricks 3 are designed as perforated bricks and the indentations 12 are holes that extend over the entire height of the bricks 3 . Provision can also be made for indentations 12 to be made in the bricks 3 or for other types of indentations 12 to be present in the bricks 3 .
  • the metal strip 9 has a longitudinal direction 24 which extends from the first fastening section 20 through the middle section 23 to the second fastening section 21 .
  • the metal strips 9 have a large number of positioning elements 11 .
  • the positioning elements 11 protrude from the plane of the metal strips 9 up and down.
  • the positioning elements 11 are arranged in the central section 23 of the metal strip 9 in the longitudinal direction 24 at a regular distance from one another.
  • the positioning elements 11 are arranged in pairs.
  • the bricks 3 are placed on the sheet metal strips in such a way that the positioning elements 11 protrude into the depressions 12 . As a result, the bricks 3 are secured in a form-fitting manner on the metal strips 9 in the direction perpendicular to the wall 2 .
  • the positioning elements 11 can be designed in such a way that they are arranged in the recesses 12 with only a small amount of play. Alternatively, an intermediate space formed between the positioning elements 11 and the depressions 12 can be filled with mortar. A different number and/or arrangement of positioning elements 11 can also be advantageous.
  • a section 16 is arranged between adjacent positioning elements 11, in which the metal strip 9 is designed as a continuous, flat flat material and in which no positioning element 11 is arranged.
  • This section 16 is intended to limit an opening 10 .
  • the section 16 has no openings, beads or bends or irregularities designed in any other way and no positioning elements. As a result, a flat, smooth delimitation of the openings 10 through the section 16 is achieved. An attractive appearance of the perforated area 5 is also achieved in this way.
  • Each metal strip 9 has a length d measured in the longitudinal direction 24 .
  • the length d is advantageously greater than the width c of the perforated area 5.
  • the metal strip 9 advantageously protrudes at one end section, in particular at both end sections, beyond the perforated area 5 into an area of the wall 2 that has no openings 10 having.
  • Different lengths of the metal strips 9 of a stiffening arrangement 8 and/or different connections of the metal strips 9 of a stiffening arrangement 8 can also be advantageous.
  • the attachment sections 20 and 21 are intended to be fixed outside of the perforated area 5 between layers of bricks 3 lying one on top of the other.
  • the fastening sections 20 and 21 are placed in the mortar layer 13 between the superimposed layers 4 of bricks 3 .
