Definitions

  • the present invention relates to a kit for producing a dry wall, consisting of at least two bricks to be arranged one above the other, each brick having at least one bearing surface which is assigned to the bearing surface of the other brick.
  • Such bricks or dry stone are known from DE-OS 27 39 017.
  • grooves are formed in the bearing surfaces in the longitudinal direction of the wall, into each of which two strips connecting the superimposed bricks are inserted. So that thrust forces can also be absorbed by the drywall, the strips inserted into the grooves must have practically no play, which makes it difficult to place the bricks on top of one another.
  • the invention is therefore based on the object of simplifying a kit of the type mentioned in such a way that it is easier to handle while saving costs.
  • the bearing surfaces have a planar, but nevertheless porous and / or partially soft surface in order to achieve an essentially flat surface such that hard stone material of a bearing surface in the pores and / or soft spots is in each case when the bricks are placed one on top of the other the other bearing surface claws.
  • the comparatively harder stone material can be formed by aggregate grains as well as by binders as well as by the stone material itself (e.g. in gas concrete blocks, porous bricks, etc.).
  • the bearing surfaces of the bricks are designed in such a way that a positive connection is established even between light, stacked stones.
  • the surface of the bearing surfaces is deliberately partially soft and porous. In this way, firmer components of the other storage area can press into the surface.
  • a flat support in the sense of the invention is understood to mean that the bearing surfaces assigned to one another have a large number of point contacts with one another, which are arranged statistically uniformly distributed over the entire bearing surface.
  • the firmer, but smaller in cross-section, binder constituents of the masonry located between the aggregate grains are positively pressed into the pores or soft spots of the other bearing surface when the masonry stones are placed on top of one another, so that the connection is free of play. It is therefore important here that the flat bearing surfaces of the bricks have a porous surface and / or are of different hardness in the stone material.
  • the surfaces of the bearing surfaces can be partially soft and porous in such a way that when the bricks are placed one on top of the other, rubbed aggregate material is pressed into the pores and / or soft spots of the bearing surfaces in the stacked state of the bricks and seals the bed joint.
  • the detached aggregate thus has a dual function.
  • the positive connection is strengthened, which further increases the resistance of a drywall according to the invention with regard to any lateral forces that may occur, and on the other hand, the abraded aggregate material also increases the sealing effect of the interlocking bearing surfaces.
  • a particular advantage of the bearing surfaces according to the invention is that any abrasion on the bearing surfaces surprisingly does not impair the masonry properties of the bricks. To achieve these advantages according to the invention it is sufficient e.g. that only the bearing surfaces consist of the binder-bound, soft, granular aggregate material.
  • the bricks can each consist of binder-bound, soft, granular aggregate material, which is significantly softer in comparison to the binder framework and e.g. consists of natural pumice, metallurgical pumice, gas concrete granulate or similar additives.
  • At least one bearing surface of a brick is machined.
  • the proportions of the soft spots are increased in the bearing surface processed in this way, while the frequency of the pores decreases.
  • the increase in the number of soft spots is essentially due to the fact that the aggregate grains are now partially cut open on the surface of the bearing surface.
  • a drywall is particularly advantageous he in which, as just described, a plan-machined bearing surface is assigned to a more porous bearing surface. This further improves the positive claw, since one bearing surface has more solid components and the other has more soft components.
  • the effective supporting surface between the two bearing surfaces is increased by pressing the solid components into the soft components, so that the pressure on the bearing surfaces decreases.
  • the grain size of the aggregate material is advantageously less than about 16 mm.
  • slots can be inserted into the bearing surfaces in the longitudinal direction of the bricks in such a way that a strip designed as a spring, which extends over the length of several bricks, into aligned slots of an upper and a lower one Storage area of bricks can be used.
  • binder from calcium silicate hydrates, e.g. B. cement stone.
  • the kit 1 comprises at least two bricks 2 arranged one above the other. For better understanding, more than two bricks 2 are shown in FIG.
  • the bricks 2 each consist of binder-bonded, soft, granular pumice material 11 (see FIG. 2).
  • Cement stone is used as a binder.
  • the bricks 2 have bearing surfaces 3 and 4 arranged at a distance from one another and plane-parallel to one another.
  • the stone also includes side surfaces 5 and 6 and abutting surfaces 7 and 8 that are plane-parallel to one another.
  • a bearing surface 3 of a brick 2 is assigned to a bearing surface 4 of the other brick 2.
  • the kit 1 is designed as a dry stone wall. To achieve this, the storage areas are. 3 and 4, as can be seen from FIG. 2 and in particular FIGS. 3 and 4, are planar, but the surface 9 or 10 of the bearing surfaces 3 and 4 is nevertheless porous and partially soft.
  • the bricks 2 placed one on top of the other are positively interlocked with one another in that the respective pumice material 11 of a bearing surface 3 or 4 is pressed into pores 12 or soft spots 13 of the other bearing surface.
  • FIG. 3 shows the surface 9 of a bearing surface 3 according to the first embodiment in a 5-fold enlargement.
  • This surface 9 is achieved in that the binder-bonded, soft, granular pumice material cures in a mold, without the resulting flat surface 9 being further processed.
  • the grainy pumice material 11 in the bearing surface 3 reaches up to the surface 9. This leaves 11 pores 12 and soft spots 13 between the grainy pumice material, which are also made of pumice, but less covered with binder, so that they are easier to press in.
  • FIG. 5 two superimposed bricks 2 are shown, the facing bearing surfaces 3 and 4 of which are designed with a surface 9, as shown in FIG. It can be clearly seen that the granular pumice material 14 is pressed into the pores 12 and the soft spots 13 of the other bearing surface 3 and 4, respectively. Rubbed pumice material, which is not shown in FIG. 5, is also pressed into the pores 12 and soft spots 13 of the adjacent bearing surfaces 3 and 4. As exaggeratedly shown in FIG. 5, the bearing surfaces 3 and 4 penetrate one another.
  • FIG. 4 also shows the surface 10 of a second embodiment of the bearing surface 3 in a 5-fold enlargement.
  • the surface 10 was achieved in that the bearing surface 3 after finishing the casting process and hardening of the stone was still flat machined, e.g. B. was face milled. This increases the proportion of soft spots 13 in the surface 10, while the proportion of the still granular pumice material 11 and the pores 12 decreases.
  • the soft spots 13 result from the fact that pumice grains now lie with a cut surface in the surface 10, so that these grains are no longer provided with a binder coating towards the surface 10.
  • FIG. 6 shows in an enlarged detail how two bricks 2 are dry-walled together when the lower brick 2 of a planed surface 10 according to FIG. 4 and the lower bearing surface 4 of the upper brick 2 have a surface 9 according to the first embodiment in FIG 3 has.
  • FIG. 6 also shows exaggeratedly how the two bearing surfaces 3 and 4 interlock to press. But it can be clearly seen that even more grainy pumice material 11 of the lower bearing surface 4 of the upper brick 2 are pressed into the soft spots 12 of the upper bearing surface 3 of the lower brick 2. As with the dry wall shown in FIG. 5, this results in a positive connection between the upper and lower brick 2. This positive locking acts in the surface direction, so that the stones are prevented from moving against each other. It is still possible to remove the stones.
  • the grain size of the pumice material 11 used is smaller than approximately 16 mm in the masonry blocks shown.
  • slots 14 and 15 running parallel to the side surfaces 5 and 6 can be machined both in the support surface 3 and in the support surface 4.
  • the slots 14 and 15 lie in a plane parallel to the side surfaces 5 and 6. If a layer of the bricks 2 is laid, a plastic strip 16 extending over the entire length of the wall can be inserted into the slot 15 of the upper bearing surface 3, which then protrudes over the surface 9 or 10 of the upper bearing surface 3. If a new layer of bricks is placed, the plastic strip 16 engages in the slots 14 of the lower bearing surface 4 of the upper brick 2.
  • the inserted plastic strip 16 essentially contributes to improving the sealing effect between the two bearing surfaces 3 and 4 of masonry stones 2 placed one on top of the other.
  • a lower layer of bricks 2 is first created.
  • the upper bearing surfaces 3 are aligned so that they are aligned.
  • a second layer of bricks 2 is then placed on the first layer of bricks 2, the grainy pumice material of the lower bearing surface 4 of the upper bricks being pressed into the surface, depending on the design 9 or 10.
  • the grainy pumice material of the upper bearing surface 3 of the lower bricks is also pressed into the surface 9 of the lower bearing surface 4 of the upper bricks 2. This creates a positive connection between the upper and lower brick, which counteracts a shift into the storage level.
  • Rubbed pumice material settles between the pores 12 or is pressed into the soft spots 13 and thus supports on the one hand the seal between the upper and the lower bricks 2 as well as their positive connection.
  • a plastic strip 16 in the lower layer of the bricks By inserting a plastic strip 16 in the lower layer of the bricks, the seal between the two layers of bricks can be additionally supported.
  • the butt joint can be designed without mortar in a conventional manner, preferably with tongue and groove teeth.
  • a stone material which is artificial e.g. is porosified by gas generators, foam or burnout substances.
  • the stone material itself forms a scaffold made of webs, which corresponds to the binder scaffold described in the exemplary embodiment.
  • the webs, which are aligned perpendicular to the bearing surface, can press into one another and cling to one another when two bricks are placed in pores and / or horizontal webs on the bearing surface of the other brick.
  • clay fired as stone material or calcium silicate hydrates hardened from lime and quartz under autoclave conditions can be considered.
