Description

The invention relates to a wall or ceiling element according to the preamble of claim 1.

US 4 094 113 A describes a wall element of this type, the wall elements having grooves on the end face and the wall elements being lined up on the end face. A rectangular profile is inserted between adjacent wall elements, which overlap U-shaped elements of the adjacent wall elements.

US 4,821,477 A describes a panel system with a similar structure, the frame elements having a rounded profile on exposed frame sides.
US 6 141 926 A. also describes free-standing wall elements that are lined up at the front, a special corner profile being provided for a corner connection in order to connect the wall elements cut for fermentation.

US 2013/312355 A1 finally describes wall elements which are put together on the front side by means of hanging elements, a separate corner profile with an approximately square cross section being used for a corner connection.

The requirements for the design of office space and office workplaces in terms of ergonomics, occupational safety, comfort and work efficiency have changed significantly over the past decade due to new profiles in the work to be carried out, changes in work organization as well as due to the densification of space. Knowledge work is increasingly carried out in flexible teams due to the complexity of the tasks. This new form of work organization and way of working requires new types of office concepts that have to meet the increased demands on communication and spatial flexibility. Because of their spatial structuring options, open space offices are the spatial concept of choice. They allow the user to design the office landscape almost flexibly. Communication zones and work zones can be planned and designed according to the requirements of the company structure and organization.

In addition to the organization of work, comfort in office space plays an increasingly important role. It has to cooperate with the increased demands on flexibility and communication. An important criterion in addition to the thermal is the room acoustic comfort, which makes it possible to work concentrated in open-space offices.

The object of the invention is, in particular, to make wall elements sound-absorbing, so that in an open-plan office, partition walls and delimited work areas can be set up with a high sound-absorbing effect. In conjunction with appropriately designed ceiling elements, closed work and meeting rooms are also to be formed, which are largely insulated from the effects of sound from the outside.

According to the invention, a wall or ceiling element is formed with the features in the characterizing part of claim 1.

In this way, an easily manageable unit with good sound-absorbing properties is formed, which can be used as a wall and / or ceiling element.

A groove is formed on the outer circumference of the frame at least on one side of the rectangular frame, in which the edges of the fabric covering are clamped by a strip. In this way, a wall element can be provided with different fabric coverings on the opposite sides. The groove for receiving the edges of the fabric covering on the end face of a wall or ceiling element can be used for receiving connecting elements which serve to connect a wall or ceiling element to an adjacent element. In this way, wall or ceiling structures can be assembled from several wall or ceiling elements.

To form a connection between wall elements or wall and ceiling elements, the groove provided on the outer circumference is formed on the side of the frame profile element on at least one side of a wall or ceiling element, the groove on the side opposite a groove on the outer circumference on the adjacent wall element. In this way, a corner connection between wall elements is formed.

To form a T-shaped wall element, an additional frame profile element is advantageously used between opposite frame profile elements of a wall element, which has a symmetrical design on both sides of the outer groove provided on the side of the frame profile element, so that on both sides of this additional frame profile element, a stiffening plate is inserted into the inner groove on the inner circumference can, while a vertically protruding wall element can be attached to the laterally attached outer groove via connecting elements.

The frame profile elements are preferably made of wood, but they can also consist of plastic.

The strips in the groove on the circumference of the wall or ceiling elements are preferably fastened by steel brackets in order to facilitate assembly.

For the sound-absorbing effect, it is advantageous if the stiffening plate is made of plasterboard or gypsum fiber material. This is also an advantage for fire protection.

The sound-absorbing layer on at least one side of the stiffening plate preferably consists of a nonwoven material, which can also be made flame-retardant. A preferably open-pore foam or a combination of foam and nonwoven material can also be provided as the sound-absorbing layer.

A partition can be assembled from individual wall elements by arranging connecting elements in the groove on the outer circumference of the wall elements, by means of which adjacent wall elements can be suspended from one another. In this case, a ceiling structure can be provided on a room, for example, which is delimited by three wall elements and can only rest on opposite sides of the wall structure.

At the connection between the ceiling elements and the wall structure, a rail with projecting legs is preferably provided, which rests on the wall and ceiling elements and can form a shadow gap between them.
A cover rail can also be provided between the wall element and the ceiling element, which, for example, carries a strip with LED elements.

The connection between a wall and a ceiling element can also be formed in the same way as a corner connection between adjacent wall elements, the outer grooves on the circumference of the two elements being opposite one another.

Fig. 1 shows the view of a rectangular wall element 1, which can have different height and width dimensions and in the cross-sectional view in 2 and 3 reproduced structure.
The wall element has a circumferential frame profile 10, which is preferably made of wood, but can also be made of another material, for example plastic. At the corners, the frame profile elements of two adjacent sides are connected to one another, for example by a 45 ° miter at an angle of essentially 90 °, it being possible for the miter surfaces to be glued or screwed together.
According to another embodiment, the frame profiles can also be butted against one another and screwed together, for example, because — as explained below — the entire wall element is covered by a fabric covering 40.

The frame composed of the frame profile elements 10 has an inner groove 11 (U-shaped in cross section) on the inner circumference ( 4 and 7 ) into which a stiffening plate 20 is inserted and preferably glued to the frame profile elements 10.

Fig. 5 shows a toothing 11.2 on the bottom of the groove 11 for receiving excess adhesive.

The inner groove 11 on the inner circumference of the frame preferably extends over the entire circumference of the frame, but it can also be provided only on at least two opposite sides of a rectangular frame for receiving the stiffening plate 20 in order to form a rigid wall element 1 or ceiling element 2 .

The reinforcement plate 20 is preferably made of plasterboard or gypsum fiber material. Another stiff material can also be used.

With 30 are in 2 and 3 Fleece layers on both sides of the stiffening plate 20 are referred to, which consist of a sound-absorbing fleece material and are designed in such a thickness that they are flush with the outside of the side faces of the frame profile 10.
Instead of an acoustic fleece 30, another preferably sound-absorbing material can also be used, for example an open-cell foam sheet.

The entire wall element 1 is preferably coated on the opposite sides with fabric 40.
The frame constructed from the frame profile elements 10 has an outer groove 12 (approximately U-shaped in cross section) on the outer circumference ( 4 and 7 ), into which the edges of the fabric covering 40 extend so that the edges can be clamped to the groove base by a flat strip 41.
In the illustrated embodiment ( 2 and 3 ) the flat strip 41 extends in its width essentially over the width of the groove bottom, the two edges of the fabric covering 40 likewise extending essentially over the width of the groove bottom and lying one above the other.
With 42 steel brackets are designated, by means of which the bar 41 made of wood or plastic is clamped to the frame profile 10 with the interposition of the superimposed edges of the fabric covering 40.

Preferably, a thin nonwoven layer 40a (fabric covering 40 and sound-absorbing material 30 ( Fig. 3 ) provided, which covers any differences in height between the frame profile 10 and the sound-absorbing material 30, so that a smooth surface of the fabric covering 40 is obtained on the visible side of the wall element 1.

The edges on the outer groove 12 and on the opposite outer sides of the frame profile 10 are beveled at 12.1, as Fig. 4 shows, so that damage to the fabric covering 40 by sharp edges is avoided.

In the middle area of the groove bottom of the groove 12 ( Fig. 4 ) A recess 12a is expediently formed so that excess material on fabric covering 40 can be accommodated in the clamping area of the groove base.

A wall element 1 constructed in this way, with layers 30 of sound-absorbing material, has a high sound-absorbing effect, so that partition walls formed from such wall elements 1, which delimit work areas in an open-plan office, strongly dampen the overall sound level.

To form a partition made of wall elements 1, in 1 to 4 described wall elements 1 placed face to face, like this Fig. 17 schematically shows. In the grooves 12 on the opposite long sides, connecting elements 50 and 51 are preferably fastened by means of screws, which are preferably screwed into the frame profile 10 in the region of the central recess or groove 12a.

Fig. 18 shows a perspective view made of a sheet metal strip U-shaped bracket 50, the angled legs are provided with a bore 50.1 for receiving a fastening screw. In the web section of the bracket 50, a slot 50.2 is formed with at least one enlarged end, which is used to receive a connecting pin 51, which is shown in perspective in FIG Fig. 19 is reproduced. The connecting pin 51 protrudes from a plate-shaped base with bores 51.1 for receiving fastening screws and has at the free end a thickening 51.2, which is inserted through an enlarged end of the slot 50.2 and held in the narrower region of the slot.

Like the cross-sectional view in Fig. 17 shows, there is a space in the groove 12 of the frame profile 10 on both sides of the connecting pin 51 for receiving cables K, which can be laid along a side edge of a wall element 1, as the perspective view in Fig. 17a shows.

The connecting elements 50 and 51 can also be designed in a different way so that a wall element 1 can be easily hung on the adjacent wall element.
Unilateral attachment is also possible, such as this Fig. 20 schematically with a U-shaped engagement portion of a bracket 50a and a T-shaped engagement element 51a.

If a partition is composed of several wall elements 1, a cover strip (not shown) can be used in the outer groove 12 exposed at the top, the cross section of which essentially fills the cross section of the groove 12 and the surface of which essentially closes with the ends of the legs of the groove 12, so that there is a smooth surface on the top of a partition. Such a cover strip can also be provided with a fabric covering and it can serve to stiffen a wall structure composed of a plurality of wall elements if the cover strip extends over the connection area between the wall elements.

Fig. 6 shows a cross section through a wall element 1 along the line AA in Fig. 1 , wherein on a long side of the frame, the frame profile in Fig. 6 10a has a cross-sectional shape, in which the outer groove 12, which serves on the one hand for fastening the fabric covering 40 and on the other hand for receiving the connecting elements 50, 51, is formed on a side surface of the frame profile 10a. This configuration serves for a corner connection with an adjacent wall element, the outer grooves 12 of the wall elements 1 adjacent at a corner being opposite one another, as is the case here Fig. 21 schematically shows. In the opposite grooves 12 after the corner connection Fig. 21 are connecting elements 50, 51 used as in an end arrangement of adjacent wall elements 1 in Fig. 17 .
Incidentally, the structure of the wall element 1 is in Fig. 6 identical to that based on the 2 and 3 explained.

Fig. 7 shows the cross section of the frame profile 10a provided for a corner connection, the same reference numerals representing the same design elements in FIG Fig. 4 correspond.

Fig. 8 shows a view of a ceiling element 2, which can be placed on four wall structures arranged at right angles to one another, so that there is a closed space with the floor on which the wall elements 1 stand.

Fig. 9 shows a cross section of the ceiling element 2, which is constructed from the same basic elements as a wall element 1.

Fig. 9 shows a sectional view along the line AA in Fig. 8 , The frame profiles 10b provided on opposite broad sides of the ceiling element 2 have an approximately L-shaped cross section, such as Fig. 11 shows in detail.

Fig. 10 shows the cross section of the ceiling element along the line BB in Fig. 8 , wherein the frame profiles 10 on the opposite long sides have essentially the same cross section as the frame profiles 10 in 2 to 4 how a comparison of the Fig. 4 and Fig. 12 shows. The only difference is that the in Fig. 4 central groove 11 in Fig. 12 is formed at a corner at 11.1 because in the case of the ceiling element 2, the stiffening plate 20 is inserted asymmetrically on the outside of the ceiling element, as the views in FIG 9 and 10 demonstrate.
The reason for this arrangement of the stiffening plate 20 on the outside of the ceiling element 2 is that low-frequency sound components can be better absorbed by the sound-absorbing surface in the form of the double-layer layer 30, so that the sound absorption overall in a closed space due to the embodiment of the ceiling elements 2 in 9 and 10 is more effective.

Even with the arrangement of the recess 11.1 on the frame profile 10.1 in Fig. 12 One side of the recess can be provided with teeth 11.2 so that excess adhesive can be received on the end face of the stiffening plate 20.

With the frame profile 10b in 9 and 11 is a stepped recess 13 provided at a corner for an in Fig. 13 reproduced corner connection provided. Essentially, the recess 13 corresponds to approximately half of the groove 12 with the groove-shaped recess 12a on the groove bottom.

How Fig. 9 shows, the fabric covering 40 is clamped in the area of the frame profiles 10b by strips 41 and 41.1 in the area of the recess 13 by means of steel clips 42, the strip 41 covering the groove-shaped recess 12a as in the embodiment in FIG 2 and 3 or in Fig. 10 .

Fig. 13 shows the corner connection between a wall element 1 and a ceiling element 2, the frame profile 10b accordingly 9 and 11 is trained. In this case, preferably in the transverse direction along the section line AA in Fig. 8 The provided corner connection is a metal rail 60 with a stepped cross-section, which rests with a protruding leg 60.1 on the groove bottom or on the bar 41 of the frame profile 10 and overlaps the leg region of the groove 12 projecting on one side with a curved central section 60.2. On the opposite, in Fig. 13 A support section 60.3 projects on the right side of the metal rail 60, on which the horizontally lying surface of the recess 13 or the bar 41.1 rests.
In this corner connection, a shadow gap is formed between the wall element 1 and the ceiling element 2 through the recess 13.

Fig. 14 shows the corner connection in the direction of section line BB in Fig. 8 between wall element 1 and ceiling element 2, a rail 61 made of metal having a different cross section being used as the covering element. In the illustrated embodiment is in the shadow gap Fig. 13 LED lighting 70 is attached to a widened section 61.3 of the cover element 61 is. An angled edge section 61.4 lies on the top of the ceiling element 2.

After in this embodiment 8 to 14 the ceiling element 2 on opposite sides through the rail 60 ( Fig. 13 ) is held, only the cover rail 61 can be placed on the other two opposite sides, which has no holding function.

How Fig. 14 shows, a ceiling element 2 can also be provided in the same way as a wall element 1 with a groove 12 on the entire circumference, so that it is not necessary to use the in Fig. 11 and 13 to provide reproduced cross-sectional shape of the frame profile 10b.

Fig. 15 shows a band raster element 80 inserted between adjacent ceiling elements 2, preferably made of sheet metal, which has a substantially U-shaped cross section with edges 80.1 angled outwards at the free edges of the legs, with a lighting strip 70 having in a groove in the center of the web portion 80.2 LED elements is used. At 90, a fan is inserted into the band grid element 80, over which a cover 91 is arranged at a distance, in which sound-absorbing material 91.1 is inserted.

The bandraster 80 rests with the projecting edge sections 80.1 on the upper side of the ceiling elements 2, a leg protruding from the edge of the covering hood 91 resting on the edges 80.1 and being fastened thereto.

Fig. 16 shows the support of a wall element 1 on a floor structure B using the groove 12 in the frame profile 10.

On the floor structure B a cross-sectionally U-shaped rail 100 is fastened, in which a support 101 rests with a threaded section which engages in a threaded bore in the web section of a U-shaped bracket 102 which rests on the bar 41 with the leg ends. The bracket 102 can also be in the form of a rail with threaded bores at least on the opposite sides of the rail.

The leg ends of the two U-shaped elements 100 and 102 engage in the groove 12 of the frame profile 10, so that a largely closed structure results.

The described construction of a wall element 1 is suitable for the design of work spaces, for example in the form of different height partition walls and for delimiting an approximately rectangular work area, wherein a door element or a window element can be provided between wall elements 1. In the case of a door element, this is preferably bordered on the outer circumference by an aluminum rail whose cross-sectional shape on the outer circumference essentially corresponds to that of the frame profile 10, so that the door element can be connected on one side with connecting elements 50, 51 to the adjacent wall element 1. In the remaining area of the circumferential groove 12 of the profile, a seal can be used on the door element.
In the same way, a window element with a circumferential aluminum frame, which carries a glass pane, can be inserted between adjacent wall elements 1.

By placing a ceiling on a rectangular work area made of wall elements 1, whereby the ceiling can be composed of ceiling elements 2, largely soundproofed work spaces can be realized in a simple manner, which can be positioned anywhere in an open-plan office.

Various modifications of the designs described are possible, for example reinforcement elements can be attached to the stiffening plate 20 in individual wall elements 1 instead of the sound-absorbing layer 30, so that shelves, monitor brackets and the like can be attached to the wall element 1.
For fastening shelves, for example, a wooden strip can run between opposite frame profiles 10, which is covered by the fabric covering 40 and is used for fastening a shelf element by means of screws.

To adapt to certain wall structures, the frame profile of individual wall elements 1 can also be formed, for example, on the top, closed, that is to say without a groove 12, the fabric covering 40 extending continuously from one side to the opposite side of the wall element over the frame profile.
In such an embodiment, the end of the groove 12 of an adjacent frame profile element 10 can be covered by the connection at a miter angle of the frame profile element which is closed on the upper side.

Various design options are possible with the design described. For example, a wall structure composed of wall elements 1 of a steep wall can be provided on one side with a colored fabric covering 40 and on the opposite side with a different color of the fabric covering 40, because the covering 40 on the opposite sides in the area of the groove 12 are separated from one another are fixed.

In the case of predetermined work areas, at least one outer wall of a work area can cover the in Fig. 10 reproduced structure, in which in contrast to the embodiment in Fig. 3 the stiffening plate 20 is arranged on the outside in order to achieve a maximum sound-absorbing effect in the interior.

The Fig. 22 shows in a perspective view, for example, an office landscape with areas formed from the wall and ceiling elements 1, 2 in the manner of a modular system. The combination of the different elements creates different zones and office areas as closed and open units that cover different uses - from kitchens and printer islands to group and individual offices - with essentially the same elements.
The wall or ceiling elements 1, 2 provided for the various designs all have the same structure, only frame profile elements on a single wall or ceiling element being adapted to the intended use. This results in a largely modular structure for office landscapes, such as in Fig. 22 shown.

In addition to the sound-absorbing design of the module elements, their fabric covering also achieves a high level of comfort.

Fig. 23 shows a perspective view of a closed room composed of wall and ceiling elements with a door T, two spaced technical band grids 100 being provided on the ceiling elements. These band grid 100 can be configured similarly to that in FIG Fig. 15 reproduced band grid 80.
Fan units for supply and exhaust air are indicated at 101 and a control unit is schematically shown at 102, by means of which the lighting, the supply and exhaust air and the like can be controlled.

Fig. 24 shows a cross section at a connection point between wall element 1 and ceiling element 2, a stepped profile 103 being fastened to the wall element, for example by means of screws, which has an angled edge 103a projecting beyond the side surface of wall element 1, on which an L-shaped cross section Suspension profile 104 made of metal rests, which is fastened to the profile element 10b of the ceiling element 2 by means of screws. This type of attachment allows greater tolerances to be accommodated between the wall and ceiling elements. With this arrangement in Fig. 24 the frame profile element 10b has a different cross-sectional shape than in FIG Fig. 9 , the recess 13 in Fig. 24 is positioned at the top.

A metal surface can be provided on the underside of the ceiling element 2, wherein a cooling device, not shown, can be provided between the metal surface and the structure of the ceiling element in order to cool the space underneath. The metal surface of the cooling device can be smooth, perforated or also covered with fabric. Furthermore, the metal surface can be pulled laterally upwards from the underside of the ceiling element 2, the hanging profile 104 being able to be integrated into the metal surface.

Fig. 25 shows a T-shaped element of the wall structure, 1 in in the middle of the preferably large-area wall element Fig. 25a a frame profile element 10a ( Fig. 7 ) is arranged, which is also on the right in Fig. 7 with the inner groove 11 is provided, so that in Fig. 7 reproduced frame profile element 10a is formed symmetrically to the center line through the outer groove 12a. In this way, on the right and left of the frame profile element 10a in Fig. 25a a stiffening plate 20 can be inserted into the inner groove 11 and a connecting element 50 ( Fig. 17 ) like a corner connection in Fig. 21 .

The in the frame of the large wall element 1 in Fig. 25 Integrated frame profile element 10a extends between the two horizontally lying frame profile elements of wall element 1.
