2. The refractory brick according to claim 1, wherein at least one profile (VP, RP, IP, AP) of said refractory brick includes brick is designed as a tongue (F) and the corresponding profile (RP, VP, AP, IP) of said refractory brick includes as a corresponding groove (N).

3. The refractory brick according to claim 2, wherein the tongue (F) and the groove (N) of the brick are arranged off-centre in a Z-direction closer to the lower side (U) of the brick.

4. The refractory brick according to claim 2, wherein the tongue (F) and the groove (N) of the bricks extend across at least 20% of the height of the brick in a Z-direction.

5. The refractory brick according to claim 4, wherein the steps are arranged off-centre in the Z-direction closer to the upper side (O) of the brick.

6. The refractory brick according to claim 1, wherein the tongue (F) and the groove (N) feature their longest extension in a Z-direction.

7. The refractory brick according to claim 6, wherein the steps of the brick extend, in the Z-direction, above the tongues/grooves (F, N) of the brick.

8. The refractory brick according to claim 1, wherein the profiles (IP, AP, VP, RP) on the inner side (I) and the outer side (A) as well as on the front side (V) and the back side (R) of the brick run at least partially at an angle that is not 90 to the corresponding side of the brick (I, A, V, R).

9. The refractory brick according to claim 1, wherein the bricks are designed wedge-shaped and tapered towards the lower side (U).

10. The refractory brick according to claim 1, where the profiles (VP, RP) on the front and back side (V, R) of the brick run offset in the Z-direction to the profiles (IP, AP) on the inner and outer side (I, A) of the brick, seen in a Z-direction of the brick.

11. Assembly according to claim 1, consisting of two segments which are running in opposite directions in the X-direction.

12. Assembly according to claim 1, wherein bricks running abreast in the X-direction (S1.1, S2.1) run offset in the Y-direction.

Description

(1) In the following, the invention is further described with the aid of the attached drawings. It is showneach in a schematic view

(2) FIG. 1: a perspective view of a brick designed according to the invention

(3) FIG. 2a: a frontal view of the back side RP(N) in the Y-direction of the brick according to FIG. 1

(4) FIG. 2b: a side view in the X-direction of the brick according to FIG. 1

(5) FIG. 3: a view in the Y-direction of a vault-like support structure with bricks according to FIG. 1

(6) FIG. 4: a view in the Z-direction from below of the support structure according to FIG. 3

(7) FIG. 5: an enlarged view of the right end of the support arch according to FIG. 3

(8) In the FIGS. 2a and 4-5, an X,Y,Z coordinate plane is schematically displayed.

(9) The brick displayed in FIG. 1 features an inner side I, an outer side A, a front side V, a back side R, an upper side O and a lower side U.

(10) The front side V and the back side R feature corresponding profiles VP, RP, namely with a groove N on the back side R and a corresponding tongue F on the front side, each of which extends across the entire width of the brick (=distance between the inner side I and the outer side A).

(11) A profile IP can be recognized as a step ST1 on the inner side I, and a corresponding step ST2 is provided as a profile AP on the opposite outer side A, wherein the profiles IP, AP extend across the entire length of the brick, thus between the opposite edges K1, K2 of the brick.

(12) Form fitted connections can be created between the bidirectional profiles VP, RP; IP, AP so that identical bricks located/arranged beside each other, or rather behind each other, interlock in a form fitted manner as displayed in FIGS. 3 to 5.

(13) 46 rows of bricks S1 . . . S46, which are arranged abreast in the X-direction and which consist of bricks S1.1, S1.2 . . . S26.1, S26.2 . . . which are arranged in a back-to-back manner in the Y-direction, can be seen schematically. Bricks S1.1, S2.1 of adjacent rows (S1, S2) are arranged offset in the Y direction.

(14) In other words: The bricks of adjacent rows of bricks S1 . . . S46 are connected in a form fitted manner via the steps ST1, ST2, while the bricks of an individual row of bricks, for example S2, feature a form-fit via the groove/tongue connections N,F back-to-back (one after the other) in the Y-direction.

(15) Overall the bricks slightly narrow between the upper side O and the lower side U, so that the vault-like support structure according to FIG. 3 can be constructed in a form-fitted manner.

(16) At the ends, the vault-like support structure rests on end bricks E which are not further described.

(17) The support structure can be accommodated in the X and Y-direction in the assembled set of the described bricks.

(18) In one embodiment with oppositely extending segments of the support arch (FIG. 3), a special end-brick-set SCH can be built into the centre, as it is generally know from the DE 39 33 744 C2.

(19) Overall, a high mechanical stability of the support arch as well as an advantageous force/load distribution in the brick system is achieved by the form fitted connection of the bricks laid abreast and back-to-back.
