Definitions

  • the invention relates to a method for producing wall elements made of concrete or the like building material with variable dimensions and / or shape on a manufacturing system and a manufacturing system implementing this method.
  • the mentioned wall elements can be, for example, more or less large-sized bricks, industrially prefabricated wall segments or entire wall panels, which are preferably made of concrete filled and compacted, but also of appropriate building materials - e.g. based on calcium silicate hydrate.
  • Known manufacturing plants have a top-open molding box with a bottom and vertical side walls, which specifies the format of the wall element to be manufactured.
  • a filling device which usually consists of a filling box open at the bottom, the molding box is filled with customarily arranged concrete material (or a corresponding building material), which is compressed by a press die which can be lowered into the molding box from above.
  • This known production system has disadvantages in that only one wall element of a single format is ever produced with one and the same molding box and the press ram coordinated with it in terms of format can be.
  • the production system In the event of a format change, the production system must be converted using mold boxes and press rams of different formats. This undesirably limits the capacity of such a manufacturing facility.
  • different formats of mold boxes and press dies must be produced and kept in stock for the production of different-sized wall elements, which means a considerable investment and storage effort.
  • at least one side wall of the molding box can be positioned at a variable distance from its opposite side wall. The result of this is that a dimension of the molding box, for example its length, can be set variably.
  • one side wall of the mold box can be displaced in height so that it can yield downwards under the action of the press ram when it is lowered into the mold box.
  • a certain variability with regard to one dimension of the wall element is already achieved by the known manufacturing plant.
  • a complete industrial prefabrication of building exterior walls requires greater flexibility in the shaping of the individual wall elements.
  • an outer wall of a building is broken down into various wall elements "like a puzzle", whereby it should ideally be achievable that all wall openings, for example for windows, doors, wall openings for vents, and inclined wall closures, such as in the gable area of an outer wall, into the shape of the individual wall elements can be included in their manufacture. It is therefore not sufficient to only be able to produce different formats, but cutouts, bevels etc. must be able to be formed in the individual wall elements. In itself, this is not possible in the case of wall element production with the known manufacturing system.
  • the invention is therefore based on the object of specifying a method for producing wall elements on a production plant with a substantially cuboid shaped, open-topped mold box that enables a high degree of flexibility with regard to dimensioning and shaping of the wall elements produced therewith.
  • the essence of the invention is the use of mold recess bodies made of an elastically compressible material in the mold box, these mold recess bodies having the shape of a straight prism with a height in the unloaded state, which corresponds to the height of the mold box.
  • a practically arbitrary tear-open shape of the wall element can therefore be achieved within the molding box, which generally has a cuboid basic shape.
  • bevels on the wall element can be produced by triangular shape recess bodies in their base area, such as are necessary for a wall element to be placed in the gable area of an outer wall of a building.
  • the molded surfaces of the recess bodies remain flat despite their flexibility and compressibility.
  • the use of the compressible form recess body also has a favorable effect in connection with the demolding of the compressed wall element.
  • the mold recess bodies When the mold recess bodies are relieved, they expand again, so that their mold surfaces adjacent to the concrete material carry out a relative displacement to the concrete material. This effectively prevents the concrete material from adhering to the mold surfaces of the mold recess bodies. The latter can therefore be removed very easily without impairing the surface quality of the wall element.
  • mold recess bodies with a limited base area it may be advantageous to place the mold recess body on the inside of the mold box - e.g. to fix on the floor or in the lower area of the side wall - preferably by a releasable glue. This prevents the mold recess body from being moved or falling over during the filling process of the molding box with concrete material.
  • a set of basic mold recess bodies within the scope of the method according to the invention, which are dimensioned and shaped, for example, according to components that regularly recur in house construction.
  • shape cut-out bodies for standardized door or window openings or for wall openings in which ventilation fans are used. Wall outlets with a clear cross-section of 20 cm x 20 cm are required for the latter.
  • a shape recess body has Forming such a wall passage this base area and a height of 40 cm corresponding to the height of the molding box if a wall element with a standard thickness of 36 cm is to be produced.
  • 1A to E has a molding box 1 which is open at the top and which is composed of a base plate 2 and four vertical side walls 3, 4, 5, 6 (see also FIG. 5).
  • the four side walls 3 to 6 are rigidly connected to one another in a frame-like manner and can be lifted up from the underlay sheet 2 by means of a lifting device (not shown).
  • a filling device 7 For filling the molding box 1 with concrete material with the side walls 3 to 6 lowered, a filling device 7 is provided, which is arranged laterally above the same with respect to the starting position of the molding box 1 shown in FIGS. 1A to C. It has a fixed base plate 8, which is aligned in the vertical direction with the upper edge 9 of the molding box 1. Furthermore, the filling device 7 has a funnel-shaped filling box 10 which is open at the bottom and which can be filled with concrete material from above by a conveying device (not shown). The concrete material is arranged on a conventional concrete mixing plant.
  • the filling box 10 can be moved back and forth in the horizontal direction above the molding box 1, as a result of which the concrete material can fall into the molding box 1 through the lower filling opening 11 of the filling box 10.
  • the width of the filling opening 11 corresponds to the width b (see FIG. 5) of the molding box 1, the extent of the back and forth movement depends on its length 1.
  • the length 1 of the molding box 1 is, for example, 2 m, its width b e.g. 1 m and the height h 40 cm.
  • the height direction of the molding box 1 corresponds otherwise to the thickness direction of the wall element produced therein, so that a wall element with a standard thickness of 36.5 cm can be produced with a molding box of a height of 40 cm due to the compression of the concrete material to be explained.
  • mold recess bodies 12 made of an elastically compressible material, such as polystyrene foam, are inserted into the empty molding box 1.
  • shape recess bodies 12 basically have the shape of a straight prism with a height H, which corresponds to the height h of the molding box 1.
  • the shape cutout body 12 has the basic shape of a right-angled triangle and is - as in the circled detailed view 1A can be seen - inserted at one end of the molding box 1 so that its shaped surface 13 practically formed from the hypotenuse of the base enables the formation of a wall element with an oblique side surface.
  • This side surface can form part of the end of a gable wall on the side facing the aisle, for example.
  • a press ram 14 is provided above the molding box 1 and can be lowered into the molding box 1 by means of a hydraulic drive device (not shown).
  • the press ram 14 has a base area which corresponds to the clear base area of the molding box 1, that is to say in the present case just under 2 m ⁇ 1 m.
  • the filling box 10 filled with concrete material is moved over the molding box 1, so that the concrete material 15 is filled into the molding space 16 remaining in the molding box 1 (FIG. 1A).
  • the trailing edge 17 of the filling opening 11 of the filling box 10 smoothes the surface of the concrete material 15 so that the molding space 16 is completely and cleanly filled with concrete material 15 (FIG. 1B).
  • the press ram 14 is lowered (arrows 18 in FIG. 1C) and thus moves into the molding box 1.
  • the concrete material 15 is compressed and, at the same time, the shape-saving body 12 is compressed in the vertical direction.
  • the compacting of the concrete material 15 can additionally be supported by a vibration excitation of the molding box 1.
  • the washer 2 is mounted on a vibration device, not shown.
  • the shape-cutting body 12 compresses only in the vertical direction, but not in bulges in the horizontal direction, since the compression pressure prevailing in the concrete material 15 counteracts such a bulging tendency. In spite of the elasticity of the mold recess body 12, the mold surface 13 thus remains flat.
  • the ram 14 is then lifted upwards together with the frame part of the side walls 3 to 6 (arrows 19, 21). This relieves the mold recess body 12 and expands into its original shape in the vertical direction. It therefore projects upwards beyond the wall element 20, as shown in FIG. 1E. It is now possible to remove the mold recess body 12 (arrow 22) and to remove the wall element 20 on the base plate 2 for complete hardening (FIG. 1F).
  • shape recess bodies 12 can be designed as full bodies (FIG. 2).
  • the shape-cutting body designated as a whole by 12 ' is divided into two partial bodies 23, 24 in a vertically extending plane.
  • the shape cutout body 12 ′′ is divided into two partial bodies 25, 26 in a horizontal plane. This embodiment is advantageous if a complete removal of the mold recess body 12 ′′ is difficult.
  • FIG. 5 shows the high variability for the shape of the wall elements 20 ′, 20 ′′ to be produced using the method according to the invention using an obvious example.
  • the mold recess bodies 12 can also have partially round basic shapes, as shown in FIG. 5 below.
  • the arch 28 formed in the wall element 20 ′′ by the corresponding shape-cutting body 12 can, for example, form the lintel of an arch window in the installed state of the wall element 20 ′′.
  • the two shape cut-out bodies 12 are fastened to the base plate 2 at the wall opening 27 or the round arch 28 by means of a releasable adhesive connection. This prevents the mold recess body 12, which is provided with a relatively small footprint, from falling over when the mold box 1 is filled with concrete material.
  • FIG. 6 shows a further alternative embodiment for a shape recess body 12.
  • the latter is in with a rigid substructure Form of a box 29 open at the top, into which an elastically compressible partial body 30 is inserted.
  • the box 29 is formed, for example, by four vertical sheet metal walls arranged in a plan view in a rectangular shape, of which three walls 31, 32, 33 are visible in FIG. 6.
  • the height H 'of the box 29 corresponds to the thickness d of the wall element 20 to be produced.
  • an intermediate floor 34 is welded between the sheet metal walls 31, 32, 33, on which the cuboidal, elastically compressible partial body 30 sits. Its upper side 35 is aligned with the upper edge 9 of the molding box 1 in the unloaded state.
  • the press die 14 now moves into the molding box 1 until it ends with the upper edges 36 of the box 29.
  • mold recess body is that although the height difference is compensated for during compression, a clean trailing edge is obtained towards the wall element 20 during the compression process, since practically the entire molded surface 13 of the mold recess body 12 consists of sheet metal.
