Definitions

  • the invention relates to a method according to the preamble of claim 1. Furthermore, the invention relates to a device according to the introductory part of claim 6 and to a ceramic component according to the introductory part of claim 9.
  • DE-C-639024 discloses a cutting device for hollow blocks, in which a cutting wire is deflected with the aid of knife-shaped holding rods, in order to obtain hollow block faces cut out in a wedge shape.
  • the invention aims to avoid the disadvantages and difficulties explained above and has as its object to enable simple and inexpensive production of ceramic components from which a support element, such as a lintel or e.g. a ceiling girder can be formed. With such a support element, no concrete should be visible from the outside on the sides of the brick shell and nevertheless there should be a continuous concrete connection in the joint area.
  • a support element such as a lintel or e.g. a ceiling girder
  • the device according to the invention for performing this method has the features defined in claim 6.
  • the invention also provides a ceramic component which is produced by the method according to the invention and which is characterized by the features specified in claim 9.
  • the plane in which the projecting edge lies is expediently oriented at right angles to the longitudinal direction of the component.
  • the adjustment of the wire support is preferably carried out by means of a template control.
  • the wire clamps are adjusted depending on the cutting process during the cutting, etc. in the opposite direction to the adjustment of the wire support, preferably by means of a template control; this enables a straight edge to be produced on all side walls of the component.
  • a preferred method is characterized in that two components are produced in a mirror image one above the other to form a common cavity and the components are trimmed together at one end, the cutting wire entering the upper component in the straight state at the start of cutting, then by adjusting the wire support and if necessary, the wire clamps are bent and, at the end of the cutting process, is again stretched in a straight line by adjusting the wire support or the wire clamps.
  • the sealing surface extends in particular at right angles to the longitudinal direction of the component, whereby it e.g. has a width of 2 to 4 mm.
  • the component then has an end face which is formed from essentially flat partial surfaces and a surface which is inclined with respect to the longitudinal direction of the component.
  • the wire support is advantageously guided on a template arranged parallel to the guide of the wire clamps, the guides of the wire clamps being expediently designed as the cutting wire opposite the cutting guide moving the wire support to achieve a straight edge.
  • a supporting element that is formed from the ceramic components according to the invention, wherein two or more components are aligned one behind the other in the longitudinal direction and the cavities and the space or spaces between the end faces of adjacent components are filled with concrete or mortar, characterized in that the Shell bodies of adjacent components lie close together and each the edge in the longitudinal direction of the components and extending around the end face on the outside of a component contacts either the string surface or the protruding edge of the adjacent component; Concrete or mortar is introduced into the gap, which is formed between the end faces of adjacent components and is sealed off from the outside.
  • a particularly good connection is provided in the joint area if the gap formed between the end faces of adjacent components and filled with concrete or mortar has a width of at least 3 mm.
  • the ceramic component 1 shown in FIG. 1 is a grooved brick shell with a shell body 2 which has a base 3 and side walls 4, 5 projecting on both sides of the base. Within the cavity 6 enclosed by the shell body 2 a web 9 is provided between the side walls to form two grooves 7, 8. The ends of the shell body open into end faces 10, which according to the invention have a special design.
  • the end face 10 is composed of partial surfaces 12, 13, 14 which are inclined relative to the longitudinal direction 11 of the component 1, each partial surface 12, 13, 14 each having one of the outer surfaces 15, 16 17 of the shell body 2 forms a section line 18, 19, 20, which represents an edge projecting in the longitudinal direction 11 of the component 1.
  • the partial surface 12, 13, 14 extend from this edge 18, 19, 20 in the direction of the center of the shell body, so are set back relative to the edge 18, 19, 20 in the longitudinal direction 11 to the junction in the cavity 6, so that the End face has a concave shape.
  • the edge 18, 19, 20 of the shell body 2 extends in a plane oriented at right angles to the longitudinal direction 11 of the component 1.
  • FIG. 2 and 3 show part of a support element 21, such as a lintel or a ceiling beam, in which Clarity was partly omitted the concrete or mortar, which is composed of components 1 shown in FIG. 1, which are identical at both ends.
  • the components 1 are aligned by contacting the two edges 18, 19, 20 of the mutually opposite end faces 10. Between the end faces 10 there is a free space 22, the maximum width of which is preferably about 3 mm, which also fills when the cavity 6 is poured with concrete 23 or mortar and thus creates a good connection in the joint area between the individual components 1.
  • a component 1 is preferably produced as described below:
  • a strand is pressed from a ceramic mass, the cross section of which corresponds to the desired cross section of a component 1.
  • Two of these parts 25 are mirror images one above the other so that they form a common cavity.
  • parts 25 are separated from the strand, the length of which is somewhat greater than the length of the finished component.
  • the ends 26 of the parts 25 are cut together with a wire cutting device 27.
  • This wire cutting device 27 has a cutting wire 29 stretched between wire clamps 28, the wire clamps 28 being guided in the cutting direction 30 along schematically illustrated guides 31.
  • wire supports 32 supporting the cutting wire 29, which can be moved transversely to the cutting direction 30 against the cutting wire 29 while bending the same on the wire supports 32 and back during the cutting process.
  • the wire supports 32 are guided on stationary templates 34 by means of rollers 33.
  • the wire clamps 28 can also be moved transversely to the cutting direction 30, in such a way that in each case the location of the cutting wire 29, which moves along an outer surface 16, 17 of the side walls 4, 5, is guided in a plane 35 directed at right angles to the longitudinal direction 11 of the component 1.
  • the transverse movement of the wire clamps 28 thus allows the offset resulting from the transverse movement of the wire supports 32 when the cutting wire 29 is bent - the size of the distance 36 of the wire clamps 28 and the distance 37 of the wire supports 32 from the outer surfaces 16, 17 of the side walls 4, 5 and also depends on the depth 38 of the transverse movement of the cutting wire 29 - compensate.
  • the cutting wire 29 is stretched in a straight line. Then it is bent according to the profiles of the templates 34 and 31 - which are designed according to the shape of the desired end faces 10 - as shown in FIG. 6.
  • the cutting wire 29 is in turn stretched in a straight line, as a result of which the outer surface 15 of the base 3 of the component 1 is given a straight edge 18.
  • the projecting edge 18, 19, 20 is formed by a flat and at right angles to the longitudinal direction 11 of the component sealing surface 39, the z. B. can be formed by a cut following the cut described above with a straight-line cutting wire 29.
  • the width 40 of the sealing surface 39 is preferably between 2 and 4 mm.
