DETAILED DESCRIPTION

[0040] FIG. 1 shows a perspective view of a partition wall 10 according to the disclosure. With the illustrated partition wall 10, the greatest number of design possibilities are to be demonstrated which are possible in the context of the present disclosure. The partition wall 10 comprises two-piece columns 14 composed of two half-columns (no. 22 in FIG. 2). In addition, single-piece columns 15; 17 are provided, which are formed from an integral square aluminum extrusion profile and which are known from the website retrievable on 10/07/2022 at the link https://www.boschrexroth.com/de/de/produkte/produktgruppen/montagetechnik/mechanik-grundelemente/schutzeinrichtungen-und-trennwande-ecosafe. For example, a 90? corner of the partition wall 10 is formed with the columns 15, wherein the half-columns according to the disclosure are fastened to the known square column 17. All columns 14; 15; 17 are equipped with the base 30 shown in greater detail in FIG. 3 at their lower end 83, wherein they are fixedly connected to the subsurface 11.

[0041] Two adjacent two-piece columns 14 or the two corresponding adjacent half-columns (no. 22 in FIG. 2) are fixedly connected to one another via an upper and a lower transverse beam 23; 24, wherein, for example, the central screw channel (no. 58 in FIG. 4) and the first undercut groove (no. 56a in FIG. 4) of a half-column are used for this purpose.

[0042] In the present case, a laminar separating element 12 is received in each rectangle, which is circumscribed by two half-columns (no. 22 in FIG. 2) and an upper 23 and a lower transverse beam 24, which separating element completely filled the respective rectangle (contrary to the illustration in FIG. 1). In the present case, the laminar separating element 12 is designed as a grid, wherein it can also be designed as a flat plate having a constant thickness.

[0043] In the region of a buckle 16 of the partition wall 10, two two-piece columns 14 are arranged directly adjacent one another, wherein the corresponding bases 30 touch one another with an articulation appendage (no. 45 in FIG. 3) and with an articulation recess (no. 46 in FIG. 3). This results in a defined gap between the two columns 14 of a buckle 16.

[0044] Reference is further made to the sliding door 80 and the swinging door 81, which are arranged according to the aforementioned website.

[0045] FIG. 2 shows a perspective partial view of the partition wall 10 of FIG. 1, wherein the direction of view is drawn into FIG. 1. It can be seen that the column 14 is composed of two half-columns 22, which directly abut one another transversely to the column axis 21. The two half-columns 22 are each made of aluminum in an extrusion process, wherein both have the constant cross-sectional shape shown in FIG. 4. However, they are installed with a 180? pivot to one another, such that the two grooves 53 face in opposite directions for receiving the laminar separating element 12.

[0046] In FIG. 2, the partition wall 10 is shown such that the underside of the base 30, which rests on the subsurface (no. 11 in FIG. 1), is visible. The base 30 is formed overall in a U-shape with a bottom 33 and two U-legs 34. The two-piece column 14 is received between the two U-legs 34, wherein it is screwed together with one of the two U-legs 34 as explained below. For this screwing, the second undercut groove (no. 56b in FIG. 4) of a half-column 22 is used, in which a groove stone is received. The associated fastening screw penetrates the respectively mated second breakthrough 42 in a U-leg 34. On the other U-leg 34, the assembly is carried out with one self-tapping screw per half-column 22. For this purpose, the two circular auxiliary breakthroughs (no. 47 in FIG. 3) are provided.

[0047] The bottom 33 comprises two fastening appendages 35 which protrude over the U-legs 34 transversely to the column axis 21. These are each equipped with a flat support surface 36, which rests directly on the subsurface (no. 11 in FIG. 1). In the region of the column 14, the base 30 is equipped with a recess 37, so that it is arranged there at a distance from the typically flat subsurface. It is thus achieved that the base rests fully on the subsurface in the region of the fastening screws, which penetrate a respectively associated first breakthrough 41 in the fastening appendage 35.

[0048] In FIG. 2, the lower transverse beams 24 can further be seen, which are fixedly connected to an associated half-column 22. These are also made of aluminum in the extrusion process, wherein they have the same cross-sectional shape as the half-columns 22. Accordingly, the laminar separating element 12 can be held directly over its entire circumference by the grooves 53 in the half-columns 22 and the upper (no. 23 in FIG. 1) and the lower transverse beam 24.

[0049] FIG. 3 shows a perspective view of the base 30 according to the disclosure. The base 30 is integrally formed, wherein, for example, it is produced from zinc in the casting process. It is symmetrically configured such that, when the base 30 is rotated by 180? around the column axis 21, the same base 30 again results. This avoids errors in the assembly of the base 30.

[0050] The base 30 is overall configured as a U-shape, wherein reference is made to the details already explained with reference to FIG. 2. The two U-legs 34 each extend with a substantially rectangular cross-sectional shape parallel to the column axis 21. They are each equipped with an articulation appendage 45 and an articulation recess 46. The articulation appendage 45 is configured as a circular cylinder that is aligned parallel to the column axis 21. The articulation recess 46 is adapted to the articulation appendage 45 such that a low-play pivot joint results when the articulation appendage 45 abuts the articulation recess 46 of an adjacent base 30. This allows for the buckle in the partition wall, which is labeled no. 16 in FIG. 1, in which two columns are arranged directly adjacent to one another at a defined, small distance.

[0051] The second and the third breakthroughs 42; 43 in the U-legs 34 are each configured as an oblong hole, which is elongated in the direction of the column axis 21. Each of the second breakthroughs 42 is associated with a circular cylindrical auxiliary breakthrough 47, which is arranged flush with the respective second breakthrough 42 in the direction of the column axis 21. A self-tapping screw can be screwed into the auxiliary breakthrough 47, which screw digs into the alignment flute (no. 59 in FIG. 4) of a half-column. Furthermore, the fact that the half-column is only equipped on one side with the second undercut groove (no. 56b in FIG. 4), which cooperates with a second breakthrough 42, is taken into account. With the auxiliary breakthrough 47, the stiffness of the fastening of a half-column on the base 30 can be increased. In particular, the bending torque that arises when a transverse force acts on the half-columns that are aligned perpendicular to the plane of the separating elements is to be pointed out here. In one direction, this bending torque is received via the screwing on the second breakthroughs 42, wherein it is received in the opposite direction by the self-tapping screws in the auxiliary breakthroughs 47.

[0052] Furthermore, reference should be made to the alignment appendages 44 extending from the bottom 33 in the direction of the column axis 21. The two alignment appendages 44a each engage with the central screw channel (no. 58 in FIG. 4) of a half-column in order to align it in relation to the base 30. Analogously, the alignment appendage 44b engages with the central screw channel of a single-piece column. In the case of a two-piece column, it is inoperable, because the third undercut groove (no. 56c in FIG. 4) is located at the relevant point. Conversely, the single-piece column also has a clearance in the region of the alignment appendages 44a.

[0053] FIG. 4 shows a cross-section of a half-column 22, wherein this cross-sectional shape 50 is preferably also used in the upper and lower transverse beams 23; 34. The outer outline of the cross-sectional shape 50 is configured so as to be rectangular with rounded corners. In the present case, the longer rectangular side 52 is exactly twice as long as the shorter rectangular side 51 so that a square column results when two half-columns 22 abut one another on the side labeled no. 84, in order to form a two-piece column. The two half-columns 22 are aligned such that the two grooves 53 for receiving the laminar separating element (no. 12 in FIG. 1) are arranged flush with one another, wherein they face in opposite directions.

[0054] The groove 53 is preferably designed in accordance with EP 918 121 B2. Accordingly, their parallel side walls 54 are equipped with a sawtooth profile, which makes it more difficult to pull out the laminar separating element from the groove 53. The aforementioned side walls 54 are oriented parallel to the shorter rectangular side 51, wherein the groove 53 is arranged at the outer edge of the cross-sectional shape.

[0055] The remaining three outer sides of the cross-sectional shape are each equipped with an undercut groove 56. The corresponding groove cross-sectional shapes 57 are T-shaped in the known manner, so that they can receive groove stones and/or hammer screws. By means of the first undercut groove 56a, which faces the open side of the groove 53, the upper and the lower transverse beam (no. 23; 24 in FIG. 1) can be fastened to the half-column 22, among other things. The central screw channel is preferably used on the upper or lower transverse beam for this fastening. By means of the second undercut groove 56b facing the short rectangular side 51 opposite the groove 53, the base (no. 30 in FIG. 2) can be fastened to the half-column 22, among other things. By means of the third undercut groove 56c, which faces the long rectangular side 52 opposite the first undercut groove 56a, the first connector shown in FIG. 5 can engage with its third appendage (no. 63 in FIG. 5), among other things.

[0056] It would be obvious to also use the third undercut groove 56c elsewhere in order to join the two half-columns 22 of a two-piece column. However, the second connector according to FIG. 6 is easier to assemble.

[0057] The present cross-sectional shape 50 is optimized for low-warpage and material-saving manufacture in the aluminum extrusion process. It therefore has a largely constant wall thickness everywhere, wherein cavities are provided in the interior.

[0058] FIG. 5 shows a perspective view of the first connector 60 from the associated two-piece column. The first connector 60 is assembled at the top end of a two-piece column, wherein it is inserted into the cavities thereof with its appendages 61; 62; 63 on the front side. The first connector 60 is integrally formed, wherein it is preferably made of zinc in the die-casting process. It can also be made of plastic, for example polyamide, in a plastic injection-molding process. The first connector 60 has a plate section 64, which is substantially designed as a flat plate with a constant thickness. The square outline of the plate section 64 is configured so as to be flush with the cross-sectional outline of the two-piece column, so that its front face is completely closed without the first connector 60 projecting laterally over the two-piece column.

[0059] A first, a second, and a third appendage 61; 62; 63 protrude from the plate section 64 in the direction of the column axis (no. 21 in FIG. 2). The first and second appendages 61; 62 are formed identically to one another, wherein they are adapted to the second undercut groove (no. 56b in FIG. 4) of the two half-columns of a two-piece column. Accordingly, they each have a T-shaped cross-sectional shape. Furthermore, they are each equipped with a screw breakthrough 65. A screw with a circular conical tip can be screwed into these, wherein the tip digs into the associated half-column in order to hold the first connector therein.

[0060] The third appendage 63 is double-T-shaped, so that it simultaneously engages with the third undercut grooves (no. 56c in FIG. 4) of the two half-columns of a two-piece column.

[0061] FIG. 6 shows a perspective partial view of the partition wall 10 in the region of a second connector 70. The second connector 70 is preferably used when very high two-piece columns 14 are used. It is preferably arranged in the middle between the base and the first connector.

[0062] The second connector 70 is preferably made of sheet metal, i.e., a laminar plate having a constant thickness, which is most preferably made of aluminum, in particular pre-anodized aluminum. The plate section 73 has a rectangular outline, wherein a total of four rectangular alignment tabs 71 protrude therefrom, which are bent 90? opposite the plate section 73. The alignment tabs 71 each plunge into an associated second undercut groove 56b on one of the two half-columns 22.

[0063] The plate section 73 is further penetrated by two screws 72, which are preferably configured as countersunk screws, wherein the screws 72 are each screwed into a groove block, which is received in an associated second undercut groove 56b and which engages rearwardly therewith, so that the second connector 70 is fixedly screwed to both half-columns 22 of a two-piece column 14 by means of the screws 72.

[0064] FIG. 7 shows a rough schematic illustration of a first assembly step of a partition wall according to the disclosure. The two bases 30, which are required for the assembly of a first partition wall module (no. 13 in FIG. 8), are positioned on the subsurface, wherein the starting base 89 of the partition wall, shown on the left in FIG. 7, is fastened to the subsurface 11 with screws 85. The screws 85 penetrate the first breakthrough (no. 41 in FIG. 3) of the base 30, wherein they are fastened by means of anchors in the subsurface 11. The subsurface 11 is, for example, the concrete floor of a production hall.

[0065] The further base 30, which is shown on the right side of FIG. 7, is only laid loosely on the subsurface 11, so that it can still be displaced during the assembly of the associated partition wall module.

[0066] FIG. 8 shows a rough schematic illustration of a second assembly step of a partition wall according to the disclosure. The partition wall module 13 according to a first embodiment shown in FIG. 8 comprises a laminar separating element 12 in the form of a grid, which is simplified. The laminar separating element 12 is associated with two half-supports 22 and one upper and one lower transverse beam 23; 24, wherein the four latter parts directly hold the laminar separating element 12 over its entire circumference. The partition wall module 13 is preferably delivered pre-assembled to the location where the partition wall is to be installed.

[0067] Starting from the state shown in FIG. 7, the partition wall module 13 is inserted into the two existing bases 30, wherein the alignment occurs in particular with the alignment appendages (no. 44a in FIG. 3) on the base 30. The base 30, which is shown on the right in FIG. 8, can still move somewhat, so that the entire construction is stress-free.

[0068] Subsequently, a half-column 87 is assembled at the beginning of the partition wall, which is not associated with any laminar separating element. The two half-columns 22, 87 of the two-piece column 14 shown on the left in FIG. 8 are connected at their upper end by means of a first connector 60. The first connector 60, with its appendages (nos. 61; 62; 63 in FIG. 5), is inserted only into the half-columns 22; 87 and preferably not yet screwed thereto. There is preferably a slight interference fit between these parts, so that a hammer can be used when assembling the first connector 60.

[0069] FIG. 9 shows a rough schematic illustration of a third assembly step of a partition wall according to the disclosure. Here, the middle partition wall module 13 is first assembled analogously to FIG. 8, wherein the right partition wall module 13 is subsequently assembled. The partition wall is thus gradually constructed so that no stresses result.

[0070] At the end, the half-column 87 shown on the right in FIG. 8 is assembled, which is not associated with any laminar separating element. This is also assembled with a first connector 60 with the associated other half-column 22 of the two-piece column 14, analogous to the half-column 87 shown on the left in FIG. 8. The first connectors 60 are also assembled onto or inserted into the remaining two-piece columns 14.

[0071] The screws 86 are gradually screwed from the starting base 89 onto the associated base 30 so that no stresses result.

[0072] FIG. 10 shows a rough schematic illustration of a fourth and final assembly step of a partition wall 10 according to the disclosure. First, the first connectors 60 are screwed from the starting base 89 to the associated half-columns 22. The corresponding screws 88 penetrate the screw breakthroughs (no. 65 in FIG. 5) on the first connector 60, as explained with reference to FIG. 5.

[0073] Then, all further bases 30, i.e., all bases 30 except the starting base 87, are screwed to the subsurface 11. The corresponding screws 86 are fastened in the subsurface 11 by means of concrete screws, for example. The screwing is carried out sequentially from the starting base 89 so that no stresses arise in the partition wall.

[0074] FIG. 11 shows a rough schematic illustration of a partition wall module 13 according to a second embodiment. By contrast to the partition wall module according to FIGS. 7 to 10, a base 30, namely the second base in the construction direction, is already fixedly screwed to the remaining partition wall module 13. This therefore does not have to be placed and positioned separately on the subsurface.

[0075] The second embodiment is more rational than the first embodiment in terms of assembly effort. However, the base 30 impedes the packaging and transport of the partition wall modules 13, so that the first embodiment is preferred.
