Kaierstein with butt joint teeth

Description

The innovation relates to a brick to |

lay in connection with butt joint teeth of the ■;

¹ ^ in the preamble of claim 1 explained type * i \

Such a brick is known from DE-GM 7230413, for example. The known brick shows in Fig. 2 |

a special embodiment, which is usually used for · f

the butt joint teeth of ΐ to be laid in a composite

Building blocks used tongue and groove connection. At |

such a connection are located on a 1

Face of the brick both elevations and depressions, with both side flanks of each depression and each elevation being designed as mating surfaces, that is, at least four mating surfaces are required for a fitting profile with two fitting strips. In the known brick are two fitting surfaces on the side flanks of the second fitting strip and

^ O two further mating surfaces are arranged on the flanks of a recess, a mating surface of the recess being extended by a side flank of the first fitting strip. This tongue-and-groove connection has the disadvantage that the fitting profiles must be manufactured with extreme accuracy, _{which is not the} case with the mass production of such stones

always succeeds. Then oversized springs are placed in normal-sized grooves or normal-sized springs in If grooves are laid with undersized dimensions, it cannot be avoided that material is scraped off the fitting profile will. This material collects in the bottom of the grooves and prevents the neighboring bricks. In the known brick, this problem is to be solved in that the Mating surfaces form a different angle to the end face, the mating surfaces of the recess are more flatly inclined than the mating surfaces of the elevations, so that the mating surfaces are only Touch linearly so that between the top surface of the elevation and the base of the opposite groove • A small gap remains in which the scraped-off material can collect. Has such a design however, the disadvantage that the power transmission in the network from one brick to the other only over the line contact can take place. There is another decisive disadvantage of the known configuration in that the side surfaces of the adjacent bricks in the composite are no longer in perfect alignment as soon as deviations from the nominal size occur within the profile. Furthermore, the pass profile is all the more more susceptible to destruction, the more mating surfaces have to be accommodated on the end face, i.e., depending the material remaining between the mating surfaces is narrower.

The innovation is based on the task of building a brick of the type mentioned to create the one

Robust design of the fitting profile also enables the bricks to be precisely aligned in the composite in the case of manufacturing-related dimensional deviations within the fitting profile.

The task is characterized by the distinguishing features of the main claim solved *

Due to the innovation according to the design of the fitting profile with. only two mating surfaces facing in the same direction point, the brick to be laid can be moved in the transverse direction with respect to the neighboring brick. Nevertheless, the bricks can be easily adjusted when laying, thanks to the equal spacing of the mating surfaces. aside from that Grooves are no longer required, in the bottom of which material scraped off the brick collect and a Can prevent joint to joint laying of the bricks. Should material be scraped off, it is enough briefly moving the brick to be laid in the transverse direction to remove the material from the contact surfaces to remove. By dispensing with a complicated design with many mating surfaces, this is according to the innovation The fitting profile is extremely robust and has good power transmission.

Due to the configuration according to claim 2, the handling (transport and stacking) both during manufacture as well as at the construction site and the risk of breakage or destruction of the fitting strips is eliminated, because this means that there are two contact surfaces on each end face.

The embodiment according to claim 3 leads to relative

narrow butt joints on the visible side of the wall built from the bricks.

The design of the brick according to claims U and 5 improves the power transmission within the Composite in addition, as this ensures that the entire head of a fitting strip of the im Composite adjacent bricks can rest on the face of the brick.

The embodiment according to claim 6 improves the handling when laying the brick and its stability while transporting.

By arranging the recessed grip according to claims 7 and 8, better relocability is achieved.

An exemplary embodiment of the innovation is explained in more detail below with reference to the drawings. Show it:

surfaces 4 can be seen. Both end faces 4 have butt joint teeth in the form of one and the same Passport profile on, since each of the end faces 4 in the longitudinal direction between the top 2 and the Underside of the brick 1 extends.

The fitting profile is shown in more detail in FIGS. It has a first fitting strip 5 and a second fitting bar |

Fitting strips 6 each have the same height h over f

the end face 4. The first fitting strip 5 is on one side of the vertical longitudinal center plane 7 of the brick ■ 1 and the second fitting strip 6 are arranged on the other side of the vertical longitudinal center plane 7. The second f Fitting strip 6 closes with the adjacent side face ^

The side flank of the first fitting strip 5 adjacent to the opposite side face 3 is designed as a first fitting face 8. The side flank of the second fitting strip 6 facing the longitudinal center plane 7 is designed as a second fitting surface 9. The first fitting strip 5 and the second fitting strip 6 each have a trapezoidal cross-section, the head width k _{1 of} the first fitting strip 5 being smaller than its foot width f ₁ and the head width kp of the second fitting strip 6 being smaller than its foot width fρ, and the two mating surfaces 8 and 9 with the end face 4 enclose the same angle. The mean distance a .. between the mating surface 8 and the longitudinal center plane 7 and the mean distance a _? between the mating surface 9 and the longitudinal center plane 7 are the same.

A first area 1o adjoins the first fitting surface 8 between the P-strip 5 and the adjacent side surface 3, which is at the level of the end face 4, is flat and whose width b ₁ corresponds to the head width k "of the second fitting strip 6 . To the second mating face 9, a second region 11 includes from the second Faßleiste 6 in the direction of the longitudinal mid-plane 7 at which is ¹ J at the level of the end face is formed flat and has a width bp, the k of the head width. the first fitting strip 5 corresponds.

Between the first fitting strip 5 and the second area 11 there is a recessed grip 12. The recessed grip 12 has such a depth g from the end face

The .Griffmulde 12 connects on one side of the longitudinal center plane 7 directly to the first fitting strip 5 and on the other side of the longitudinal center plane 7 directly to the second flat area 11, the vertical boundary surfaces of the recessed grip 12 also obliquely at an angle to the face 4 bump. In this way, the space available on the face is fully utilized for extremely robust, large-area butt joint teeth.

The innovation is not limited to the exemplary embodiment described and drawn. The refinement according to the innovation with two fitting strips and with only two fitting surfaces pointing in the same direction can, for example, also be designed without or with a much narrower recessed grip. It is also not absolutely necessary for the second fitting strip to be flush with the adjacent side surface, for example when the butt joint is to be mortared. ^ ⁰ . A good power transmission can still be given, for example, if only the head of a fitting strip hits an opposing flat area.
