This application claims priority under 35 U.S.C. § 119 to application no. DE 10 2022 212 544.4, filed on Nov. 24, 2022 in Germany, the disclosure of which is incorporated herein by reference in its entirety.
The present disclosure relates to a partition wall, a base for use in the aforementioned partition wall, and a method of assembly of the partition wall.
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, a partition wall is known, comprising a plurality of parallel columns, each being fastened to a subsurface by means of a separate base. Laminar separating elements are arranged between the columns, which can each be designed as a grid or as a flat plate having a constant thickness. The laminar separating elements are each enclosed by a frame over their entire rectangular circumference, wherein the frame, as well as the columns, are designed as aluminum extrusion profiles. A frame is fastened between two associated columns in order to hold the laminar separating element between the aforementioned columns.
For example, the above partition wall is the subject-matter of EP 918 107 B1, EP 918 121 B2, and EP 968 345 B1.
An advantage of the present disclosure is that less material is required in order to build a partition wall of comparable size. Furthermore, the partition wall according to the disclosure can be erected more quickly than the known partition wall. To the extent that the weight of the partition wall modules discussed below is small enough to be carried by one person, the entire partition wall can be erected by a single person.
According to the disclosure, it is proposed that at least one portion of the columns, namely the two-piece columns, is composed of two separate half-columns, wherein the half-columns are each configured so as to be elongated with respect to the associated column axis, wherein they abut one another transversely to the respective column axis, wherein both half-columns of a two-piece column are directly fastened to the base associated with the two-piece column, wherein an associated laminar separating element is directly fastened to at least one half-column of a two-piece column.
The laminar separating element can be a grid or a flat plate with a constant thickness. The aforementioned plate is preferably translucent or milky-cloudy, for example made of acrylic glass. However, it can also be opaque. The outline of the laminar separating element is preferably rectangular, wherein two opposing rectangular sides extend parallel to the column axes. The column axes are preferably aligned parallel to the direction of gravity. The half-columns preferably abut one another directly. In particular, the two-piece columns at the end or on a buckle of the partition wall can be associated with a semi-column, to which no laminar separating element is fastened, wherein a laminar separating element is fastened only to the other half-column of the aforementioned two-piece column. Preferably, all columns are associated with a respective single base. The base is preferably integrally formed. The laminar element is preferably received in a groove of the associated half-column in order to fasten it directly to the half-column. The groove is preferably designed in accordance with EP 918 121 B2.
Advantageous developments and improvements of the disclosure are specified herein.
It can be provided that both half-columns of a two-piece column extend with a constant cross-sectional shape along the respective column axis, wherein the two cross-sectional shapes are configured identically such that both aforementioned half-columns can be produced from the same blank. The aforementioned blank is preferably made of aluminum in the extrusion process. The two half-columns of a two-piece column are preferably assembled at a 180° angle to one another with respect to a turning axis perpendicular to the column axis, so that, in the simplest case, two mirror-image cross-sectional shapes result when both half-columns of a two-piece column are viewed in a common sectional view.
It can be provided that, between two adjacent two-piece columns, a respective top and a respective bottom transverse beam are arranged, wherein these two-piece columns extend spaced apart from one another in parallel between the two associated two-piece columns, wherein they are each fastened at their two opposite ends directly to a respectively associated half-column, wherein a laminar separating element is directly fastened to the two associated half-columns and the associated upper and lower transverse beams over its entire circumference. The upper and/or the lower transverse beams each extend perpendicular to the column axis. The half-columns and the upper and lower transverse beams each have a groove in which the laminar separating element is directly fastened.
It can be provided that the upper and/or the lower transverse beams each have a constant cross-sectional shape along their entire length, which is configured so as to be identical to the cross-sectional shape of the associated half-columns, such that the half-columns and the upper and lower transverse beams can be produced from the same blank. Thus, only a single extrusion tool is required for the aforementioned parts, so that they are particularly cost-effective to manufacture. The preferred grooves for fastening the laminar separating element are arranged in a mating manner such that the aforementioned parts can directly hold the laminar separating element over its entire circumference.
It can be provided that an outer outline of the cross-sectional shape of a half-column comprises a rectangle having a shorter and a longer rectangular side, wherein the aforementioned cross-sectional shape forms a groove for receiving the associated laminar separating element, wherein the groove has two opposing side walls, which are respectively arranged parallel to the shorter rectangular side, wherein the two half-columns of a two-piece column abut one another on their longer rectangular sides. Thus, the base explained further below can be used for both the two-piece column as well as for the known single-piece column. The longer rectangular side is preferably twice as long as the shorter rectangular side, so that a two-piece column has a square outer outline overall. The side walls of the groove are preferably designed in accordance with EP 918 121 B2, i.e., sawtooth-like.
It can be provided that the upper transverse beam is arranged flush with a top end of the two associated half-columns. The upper and lower ends of a column and/or a half-column are arranged at opposite ends of the column and/or the half-column with respect to the column axis. “Above” and “below” preferably relate to the direction of gravity.
It can be provided that the two half-columns associated with a lower transverse beam protrude downwardly over the respective lower transverse beam, such that the lower transverse beam is arranged at a distance from the associated bases. The partition wall module explained below can thus be assembled in a particularly simple manner.
It can be provided that the two half-columns of at least one two-piece column are fixedly connected to one another at their upper end by means of a first connector, wherein the first connector has at least one appendage extending in the direction of the column axis, wherein each appendage engages on the front side with at least one associated half-column, such that, taken together, all appendages engage with both half-columns of the aforementioned two-piece column. The first connector is preferably integrally formed. It preferably has a plate section on which the at least one appendage is arranged. The plate section is preferably formed as a flat plate having a substantially constant thickness. It preferably completely covers the associated front face of the two-piece column, wherein its outer outline is configured so as to be aligned flush with the outer outline of the respective two-piece column. The first connector is preferably configured as a cast part or a die-cast part, wherein it can be made of zinc, aluminum, or plastic. The at least one appendage preferably has a constant cross-sectional shape in the direction of the column axis.
It can be provided that at least one two-piece column is associated with at least one respective second connector, wherein the two half-columns of the aforementioned two-piece column are equipped with at least one respective undercut groove, which extends with a constant groove cross-sectional shape along the relevant column axis, wherein the aforementioned second connector is fixedly connected to two undercut grooves, wherein these two undercut grooves are each associated with another of the two aforementioned half-columns. The aforementioned groove cross-sectional shape is preferably T-shaped. The two undercut grooves to which the second connector is fixedly connected preferably face in the same direction. By means of the second connector, particularly high two-piece columns can be realized.
Protection is also disclosed for a base for use as a component of a partition wall according to the disclosure, wherein the base is U-shaped with a bottom and two U-legs, wherein the U-legs extend parallel to the column axis, such that a column is receivable between the two U-legs, wherein the bottom protrudes with a respective fastening appendage perpendicular to the column axis on two opposite sides via the two U-legs, wherein both fastening appendages have a respective first breakthrough, via which the base can be fastened to the subsurface, wherein both U-legs comprise two respective second breakthroughs, to each of which a half-column can be fastened. The base is preferably symmetrically configured such that, when the base is rotated by 180° around the column axis, the same base again results. The two second breakthroughs of a U-leg are preferably arranged transversely to the column axis at a distance to one another. Preferably, both U-legs each have a third breakthrough, the layers and shape of which are adapted to a single-piece column, which is receivable between the U-legs. The U-legs preferably extend with a constant, substantially rectangular cross-sectional shape parallel to the column axis.
It can be provided that an articulation appendage and an articulation recess are arranged on at least one U-leg, wherein the articulation appendage is formed by a circular cylinder extending parallel to the column axis, wherein the articulation recess is adapted to the articulation appendage such that a pivot joint results when the articulation appendage of a base abuts the articulation recess of another base. The articulation appendage is preferably formed integrally with the associated U-leg. By means of the articulation appendage and the articulation recess, the buckle shown in
Protection is further disclosed for methods of assembling a partition wall according to the disclosure, wherein the method comprises the following steps, which are preferably carried out in the stated sequence:
Step d) is preferably repeated until all partition wall modules provided according to step a) are assembled. As part of steps c) and d), the second base can be pre-fastened to the partition wall module so that it is a component thereof. It is then positioned on the subsurface by aligning the entire partition wall module. It is also possible to pre-position the second base on the subsurface, wherein the partition wall module is fixed to the first and second base as part of steps c) and d). The latter alternative is preferred, because the partition wall modules are easier to pack in a more space-saving manner. In the first mentioned alternative, the (second) base protrudes in an unfavorable manner from the remaining partition wall module. The base that is assembled first of all is referred to as the starting base in the context of the present application.
It can be provided that, immediately after both half-columns of a two-piece column are fastened to the associated base, a first and/or a second connector is fastened to this two-piece column. The first connector is preferably only inserted in this case, wherein, only after a preferably longer section of the partition wall has been provisionally erected, it is screwed onto the two associated half-columns.
It can be provided that, with the exception of the first positioned base, all remaining bases are fixedly connected to the subsurface after assembly of all partition wall modules. The first assembled base, also referred to as the starting base in the context of this application, is preferably fastened to the subsurface prior to assembly of the first partition wall module.
It is understood that the aforementioned features and the features yet to be explained below can be used not only in the respectively specified combination but also in other combinations or alone, without leaving the scope of the present disclosure.
