Definitions

  • the invention relates to a method for producing wall elements made of concrete or similar building material with variable dimensions and / or shaping on a production line and one of these methods implementing manufacturing plant.
  • the wall elements mentioned can be more, for example or less large-sized bricks to make industrially prefabricated Act wall segments or entire wall panels, which are preferably made in Forms filled and compacted concrete, but also from corresponding Building materials - e.g. based on calcium silicate hydrate become.
  • Known manufacturing plants have a mold box open at the top a floor and vertical sidewalls that match the format of the item to be manufactured Wall element pretends.
  • a filling device which in the Usually consists of a filling box open at the bottom, the molding box with customarily arranged concrete material (or a corresponding building material) filled, which can be lowered into the mold box from above Ram is compressed.
  • This known manufacturing system has disadvantages in that one and the same molding box and the one that matches the format Press stamps only ever made wall elements of a single format can be.
  • the production system must be converted weden by using different-sized mold boxes and press stamps become. This undesirably limits the capacity of one Manufacturing facility. They also have to be of different sizes for the production Wall elements according to different formats Molded boxes and press dies are manufactured and kept in stock, which means a considerable investment and storage effort.
  • a certain remedy for the problem discussed above creates already a manufacturing system, as known from DE 44 08 845 A1 is.
  • this manufacturing system there is at least one side wall of the molding box with a variable distance to the opposite side wall positionable. This ensures that one dimension of the molding box, for example, its length can be set variably.
  • one side wall of the molding box is height-adjustable, so that they are under the action of the press ram can give way down when it is lowered into the molding box.
  • the known manufacturing system already has a certain variability achieved in terms of a dimension of the wall element.
  • complete industrial prefabrication of building exterior walls requires greater flexibility in the shape of the individual wall elements.
  • an outer wall of the building is used disassembled into different wall elements "like a puzzle", optimally should be achievable that all wall openings e.g. For Windows, doors, wall openings for ventilation and sloping ones Wall closures, such as in the gable area of an outer wall into which Shape of the individual wall elements included in their manufacture can be. So it is not enough to just produce different formats to be able to, but it must be in the individual wall elements Cutouts, slants, etc. can be trained. This is in itself in the production of masonry elements with the well-known manufacturing plant not possible.
  • DE 1 036 740 B describes a mold with a mold recess body known for the production of wall elements made of concrete, the two sheet metal profiles includes which define a cavity.
  • the lower sheet profile lies with its bottom plate on the bottom plate of a molding box, while the cover plate of the upper sheet metal profile one when compacting the concrete material retracting ram touches. Between the two plates extend compression springs that when lifting the ram Push the upper sheet profile back into its starting position before loading. Due to the relatively complicated structure, such a shape-cutting body is not for the economical production of any wall element elevation forms or of recesses with special dimensions in Suitable for wall elements.
  • the cavity body consist of a relative stiff material such as B. metal and can from individual standard elements be put together.
  • the invention is therefore based on the object of a method for Manufacture of wall elements on a production line with an essential cuboid, open-topped mold box indicate that a high degree of flexibility with regard to dimensioning and shaping of the wall elements thus made possible.
  • the crux of the invention is Use of recess bodies made of an elastically compressible Material in the molding box, this molding recess body Have the shape of a straight prism with a height in the unloaded state, which corresponds to the height of the molding box.
  • this mold cavity can usually be a cuboid within the Basic shape-containing mold box a practically any tear-open shape of the wall element can be reached. So through in their Base area triangular shape recess body bevels on the wall element are generated, such as in the gable area of an outer wall of a building wall element to be placed are necessary.
  • the shaped surfaces of the recess bodies remain despite them Flexibility and compressibility.
  • the use of the compressible form recess body has an effect also in connection with the demolding of the compressed wall element cheap. Expand when relieving the mold recess body these again, so that their adjoining the concrete material Carry out a form shift to the concrete material. This prevents the concrete material from adhering to the mold surfaces of the mold recess body effectively prevented. The latter can do a lot can be easily removed without affecting the surface quality of the wall element affect.
  • shape-cutting bodies with a limited base area be the mold recess body on the inside of the mold box - e.g. on the floor or in the lower area of the side wall - preferably to be fixed by a detachable adhesive. This prevents that the cavity body during the filling process of Mold box with concrete material is crazy or falls over.
  • a set of basic cavity bodies which e.g. dimensioned according to regularly recurring components in house construction and shaped.
  • recess bodies for standardized door or window openings or for wall openings name in which ventilation fans are used are required.
  • wall openings are required with a clear cross section of 20 cm x 20 cm.
  • a shape recess body has Formation of such a wall passage this base area and one of the Mold box height corresponding height of 40 cm if a wall element should be manufactured with a standard thickness of 36 cm.
  • the manufacturing plant shown in FIGS. 1A to E has an open top Molding box 1, which consists of a base plate 2 and four vertical Side walls 3, 4, 5, 6 (see also Fig. 5) is composed.
  • the four Side walls 3 to 6 are rigidly connected to one another in a frame-like manner via a lifting device, not shown, from the underlay sheet 2 can be lifted off.
  • a filling device 7 For filling the molding box 1 with concrete material with the side walls lowered 3 to 6, a filling device 7 is provided, which with respect 1A to C the starting position of the molding box 1 shown laterally is arranged above the same. It has a fixed base plate 8 on, aligned in the vertical direction with the upper edge 9 of the Shaped box 1 is arranged. Furthermore, the filling device 7 has a open at the bottom, funnel-shaped filling box 10, of above by a conveyor with concrete material, not shown can be filled. The concrete material is on a conventional concrete mixing plant done.
  • the filling box is for introducing the concrete material into the molding box 1 10 can be moved back and forth in the horizontal direction over the molding box 1, whereby the concrete material through the lower filling opening 11 of the filling box 10 can fall into the mold box 1.
  • the width of the fill opening 11 corresponds to the width b (see FIG. 5) of the molding box 1, the extent the back and forth movement depends on its length 1.
  • the is Length 1 of the molding box 1 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 to remaining the thickness direction of the wall element produced therein, so that with a molded box a height of 40 cm due to the still to be explained Compacting the concrete material with a wall element Standard thickness of 36.5 cm can be produced.
  • the recess body 12 made of an elastically compressible material, e.g. polystyrene foam inserted into the empty molding box 1.
  • This shape recess body 12 basically have the shape of a straight prism with a height H on, which corresponds to the height h of the molding box 1. In the shown in Fig.
  • the shape recess body 12 has the basic shape a right-angled triangle, and is - as in the circled detail view 1A - at one end of the molding box 1 used so that its practically from the hypotenuse of the base Formed surface 13, the formation of a wall element with a sloping side surface allows.
  • This side surface can e.g. form part of the end of a gable wall on the aisle side.
  • a press ram 14 is provided above the molding box 1 is, via a hydraulic drive device, not shown can be lowered down into the molding box 1. Accordingly, the Press ram 14 on a base that the clear base of Molding box 1 corresponds, that is, in the present case, just under 2 m x 1 m is.
  • the ram 14 is then lowered (arrows 18 in 1C) and thus moves into the molding box 1. This will make the concrete material 15 compresses and at the same time the shape recess body 12 compressed in the vertical direction.
  • the compression of the concrete material 15 can additionally be supported by a vibration excitation of the molding box 1 become.
  • the washer 2 is on a not shown Vibrating device stored.
  • the shape-saving body 12 only compressed in the vertical direction, but not in bulges in the horizontal direction, since that prevailing in the concrete material 15 Compaction pressure counteracts such a bulging tendency. Despite the The elasticity of the mold recess body 12 thus remains the mold surface 13 just.
  • the press ram 14 is also subsequently together with the frame part of the side walls 3 to 6 further up lifted off (arrows 19, 21).
  • the shape recess body 12 relieves and expands vertically to its original Shape. So he stands above the wall element 20 upwards, as in 1E is shown.
  • the shape cutout body 12 can now removed (arrow 22) and the wall element 20 on the washer 2 to completely hardened away (Fig. 1F).
  • shape cutout bodies 12 be designed as a full body (Fig. 2).
  • FIG. 3 An embodiment of the invention is that designated as a whole by 12 ' Molding recess body in a vertical plane in two part bodies 23, 24 shared. 4, the shape recess body 12 " divided into two partial bodies 25, 26 in a horizontal plane. This embodiment is beneficial if a complete removal of the cavity body 12 "is difficult.
  • Fig. 5 makes the high variability for the shape of the with the invention Method of producing wall elements 20 ', 20 "on one obvious example clearly.
  • the shape cutout body 12 can also have partially round basic shapes have, as shown in Fig. 5 below.
  • the one in the wall element 20 "round arch formed by the corresponding shape recess body 12 28 can for example in the installed state of the wall element 20 " form the lintel of an arched window.
  • FIG. 6 shows a further alternative embodiment for a shape recess body 12 shown.
  • the latter is in with a rigid substructure Form of a box 29 open at the top, in which an elastically compressible Partial body 30 is inserted.
  • Box 29 is for example through four vertical sheet metal walls arranged in a plan view in a rectangular shape 6, three walls 31, 32, 33 of which are visible in FIG.
