Definitions
- the invention relates to a molded block for coke ovens, each of which has two vertical partitions, which are connected to one another in a tensile manner by transverse binders, so that trains are formed between them and which are at an acute angle to one another such that their distance is greater than one another the entire wall length changes by the dimension v, the shaped block being limited by a lower surface and an upper surface parallel to it, which surfaces are flat except for grooves and projections for a positive connection.
- the coke ovens known from German patents 20 56 119 or 23 31 834 are made from relatively small-sized shaped blocks.
- a large number of different stone formats are required if the individual stones are in engagement with one another via a form-fitting connection of tongue and groove.
- This variety of formats causes problems when relining coke oven chambers and leads to a high level of work, but is disadvantageous in particular in the case of repairs, since it cannot be foreseen which individual stones are in need of repair, so that all types of shaped stones that occur are always in stock must be kept. This leads to costly stockpiling. .
- This task is based on the shape of the aforementioned
- the shaped block has the thickness of a partition and has both a coke-side, flat side surface, and a train-side, flat side surface, that from the train-side side surface protrudes a binder area that the binder area on the upper surface and on the lower surface has at least one projection or a groove, which run transversely to the longitudinal direction of the truss area, bring about a positive connection of stacked shaped stones and have a distance from the free end of the truss area which is significantly larger than the dimension v, and that the Groove or the projection extends in the binder direction over a width that is greater than v.
- the basic idea of the invention is to use shaped bricks which have both a wall area which delimits the wall in contact with the coke and a binder area which creates a tension-resistant cross connection and separates the individual trains in the longitudinal direction.
- the shaped block according to the invention has a truss area which is designed in its length for the largest truss length occurring.
- the truss area is shortened by sawing in order to be able to create the shorter trusses. This makes it possible to produce the ver ⁇ tical areas of coke oven chambers of a very small number of molded bricks. Apart from special stones for the head areas, two different formats are sufficient, for example, to create the masonry.
- the binder regions of the shaped blocks are shortened by sawing off, this leads to the grooves or projections provided on the upper side and the lower side of the binder no longer being one have a constant distance from the opposite partition.
- the sawing takes place instead of in an end piece of the binder area, in which there are either no projections and grooves or at a distance from them, so that the grooves or projections are still sufficiently adequate even for the shortest possible binder area Have a distance from the free end of the truss area created by sawing so that they can fulfill their function, that is to say transmit tensile forces in the truss direction.
- the groove and / or the projection is oversized.
- the part of the relatively wide groove that is not required for the intervention is filled with mortar, or the excessively wide projection is shortened before joining and mortaring in such a way that it is suitable for the concrete binder to be produced. fits.
- the shaped block according to the invention can be adapted to the respective geometric requirements by simple cutting work which can also be carried out on site. This considerably reduces storage.
- the replacement stone required for a defective molded stone can be created at the place of use without having to manufacture it again, as in the prior art, which is time-consuming and labor-intensive.
- each lower surface and each upper surface of a binding region has at least one protrusion or groove, so that when the stack is stacked, the protrusion and groove engage. If only one groove, for example on the upper side and only one protrusion, for example on the lower side, is provided, these must be made so wide that an engagement is achieved for all occurring tie lengths. If the projection is narrow transversely to the direction of the tie, this requirement can be met by a sufficient width of the groove in the corresponding direction. If one chooses from the outset a relatively wide projection, this can be shortened by cutting or grinding so that it engages in the groove provided.
- grooves or several projections can also be provided. These are then distributed over the length of the binder area so that at least one projection always engages in a groove.
- the projection that is not required is ground off. In this way, the overall width of the grooves can be reduced.
- the invention also relates to a method for producing coke oven chambers with the aid of the shaped blocks according to the invention.
- the truss areas of the shaped blocks are shortened so that the truss length required can be created. If necessary, the projections are also shortened or partially cut away.
- the method according to the invention makes it possible to build coke oven chambers with very few joints. This on the one hand reduces the time for bricklaying, but on the other hand also reduces the number of weak points, as are typically formed by joints.
- T-shaped shaped stones with two different lengths of the T-beam then with two formats alone the side boundaries, ie the partitions, of coke oven chambers can be created, apart from special formats on the heads. Cross joints are avoided due to the different lengths of the T-beams of the two bricks.
- FIG. 1 is a perspective view of a wall of a coke oven chamber, which is created from shaped blocks in two different starting formats
- FIG. 2 is a plan view of a first shaped block in T-shape with a long T-bar according to the embodiment of FIG. 1,
- Fig. 3 is a plan view of a second shaped block with a short T-beam according to the embodiment.
- Fig. 1 is a plan view of a second shaped block with a short T-beam according to the embodiment.
- FIG. 4 shows a vertical section through the binder area in the exemplary embodiment according to FIG. 1,
- FIG. 5 is a sectional view similar to FIG. 4, but for shaped blocks with two projections on one side and two grooves on the other side,
- Fig. 6 is an illustration corresponding to FIG. 4, but for shaped blocks with two projections on one side and a groove on the other side and
- FIG. 7 shows a representation corresponding to FIG. 4, but for shaped stones with a projection that is much too wide in the starting point on one side and a groove on the other side, the projection is shown in broken lines Area has been removed.
- Fig. 1 to Fig. 4 is made of prefabricated parts with two different formats. Both formats, namely shaped blocks 10, 12 (seen from above) have a T-shape, the shaped block 10 having a longer T-beam than the shaped block 12. Both shaped blocks 10, 12 also each have a binder area 14, 16, wherein shown in FIG In the exemplary embodiment, the binder area 14 of the shaped block 10 is significantly shorter than half a tie length and the binder area 16 of the shaped block 12 is significantly longer than half a tie length. Cross joints are avoided by the different lengths of the T-beams and the different lengths of the binder regions 14, 16, this can be seen from FIG. 1.
- the T-beams form the partitions. Accordingly, the T-beams have a wall thickness that corresponds to the thickness of a partition.
- the T-beams of the shaped blocks 10, 12 each have a flat side surface 18 on the coke side and a flat side surface 20 on the train side. The latter is interrupted by the centrally projecting binder region 14 and 16, respectively.
- the shaped blocks 10, 12 each have a flat, lower surface 22 and a parallel, flat upper surface 24, which are at right angles to the side surfaces 18, 20 mentioned. These surfaces 22, 24 are interrupted by grooves and projections, which will be discussed below.
- protrusions 25 each run in the lower surfaces 22; they have essentially a semicircular cross section. These projections 25 are also located on an end face of the T-beams, namely in the case of the left partition according to FIG. 1 on the side facing the viewer and according to the right partition. 1 on the opposite side.
- the lower surface 22 of the shaped block 12 has a projection 26 in the binder area 16, which extends transversely to the direction of the binder. It will be discussed in more detail below since it is essential for the invention.
- protrusions 28 protrude on the lower surfaces of the shaped blocks 10 in the region of the T-beams, which extend transversely to the abovementioned protrusions 25, cross them and have a distance from the end face that is a quarter of the difference between the Corresponds to bar lengths.
- Corresponding grooves 30 are provided on the upper surface of the shaped block 10 with the longer T-beam in the same place.
- the projections 28 engage in the grooves 30, as can be seen from FIG. 1.
- Grooves 31 are also arranged on the upper surface 24 and the other end face of each shaped block 10, 12, which also have a semicircular profile and interact with the projections 25 already mentioned.
- a groove 32 is formed on the upper surface 24 of the shaped block 10 with the longer T-bar and has a relatively large width in the direction of the binder. It cooperates with the projection 26, both of which are discussed separately.
- the two truss areas 14, 16 are so long overall that they result in the length of the longest truss between the partition walls when they are butted together with a mortar joint.
- the shorter binders are produced in that either the binder area 14 of the molded block 10 and / or the binder area 16 of the molded block 12 is shortened. 3, the binder area 16 is shortened, this is indicated by a dash-dotted line 34.
- the longest occurring binder is approximately the same dimension, but less a few millimeters, longer than the shortest occurring binder.
- the binder area 16 must be shortened by the corresponding dimension, for example 80 mm, in order to produce the shortest possible binder.
- a corresponding calculation applies to the width of the groove 32 (measured in the direction of the binder). Its total width is the sum of the reduced dimension v mentioned, ie in the example about 80 mm, the width of the projection 26 and the width of two mortar joints. This leads to a typical overall width of the grooves of approximately 120 mm.
- the groove 32 begins at a distance from the free end face of the binder region 16 which is significantly larger than the dimension v. This ensures that when the binder area 16 is cut to length, the groove 32 is not touched, but rather sufficient material remains between it and the free end of the binder area 16 for a positive engagement and retention of the projection 26.
- Fig. 4 shows the state between two shaped stones 12 for the shortest possible binder, the assignment of these stones 12 for the longest possible binder is indicated by dash-dotted lines. 4 shows, the projection 26 is at a distance from the left end of the groove 32, which is only the width of a mortar joint. Likewise, for the longest possible binder, the projection 26 is so close to the right end of the groove 32 that there is only room for a mortar joint. For all the tie lengths in between, the projection 26 is in a position which lies between the two extreme positions shown.
- both binder regions 14, 16 can also be shortened in order to produce binders that are shorter than the longest binder.
- Fig. 5 shows an embodiment which aims to avoid relatively wide grooves.
- two protrusions 26 of the same type are provided, and two grooves 32 are assigned to them.
- 5 shows the position of two shaped stones 12 for the case of a binder, the length of which lies exactly in the middle between the longest and the shortest binder.
- the left projection 26 is separated by a mortar joint at the right end of the left groove 32 and accordingly the right projection 26, again separated by a mortar joint, is close to the left end of the right groove 32.
- the right projection 26 is ground off. The left protrusion is removed for trusses with shorter overall lengths.
- two projections 26 are also provided, but only one groove 32 is assigned to them. Again, the case for the medium length truss is shown. If shorter binders than shown are to be created, the left projection 26 is removed. Accordingly, the right projection 26 is removed if longer trusses than shown are to be bricked.
- FIG. 7 finally shows the case of a projection 26 which is excessively wide in the beginning and which is adapted by cutting off the respective desired tie length.
- the exemplary embodiment shown is the shortest possible Binder shown.
- the right, dash-dotted portion of the projection 26 is removed.
- the situation looks like a mirror image for the longest possible binder, only a left part of the projection 26 is removed here. For all lengths in between, the projection 26 must be cut on the left as well as on the right.
- the shaped blocks 10, 12 are made of melted silicate, they are hydraulically bound, they are neutral, so they have practically no thermal expansion.
