Abstract

A wall element is proposed which makes it possible to manufacture inner wall elements of any desired wall thickness, having different intermediate layers between their sheet metal facing panels depending on the requirements, and provided with means for joining the wall elements along their front edges. The facing panel (11)on either side of the wall element is made of sheet metal, preferably sheet steel, and has an inwardly directed return (11.1) on each front end. Each return (11.1) has an interlocking edge directed inward at an acute angle. Two panels (11) are joined together along their front edges by a locking rail (14.1, 14.2). The locking rails (14) consist of profile strips whose folded back edge strips (15) co-operate with the edges of the returns (11.2) and thus hold the panels together. The locking rails (14) have interlocking elements, for example slots (18) and corresponding projections (16), arranged at appropriate heights.

The invention relates to wall elements that are planked on both sides and can be connected to one another for interior construction, in particular for rooms used for manufacturing or other purposes, e.g. clean rooms in medicine, pharmacy and technology, laboratories, rooms for special productions or the like, whereby between the planking there are

- ~ stiffeners, filling materials or the like are provided.

For interior work, especially for temporary interior work in rooms used for production purposes, wall elements are joined together to form the surrounding walls of the rooms. Be there

~ - these wall elements according to the requirements of the

Rooms are selected so that different planking materials and different reinforcements and different fillings result from case to case. Do the spaces to be formed belong to different

- ventilation zones, is airtight when joining To achieve completion. This applies particularly to clean room technical areas in which the clean room zone is flooded with a low-turbulence displacement flow in order to be at least approximately free of particles in the production area

- to reach. However, this also applies to laboratories or special productions that take place separately from other rooms in terms of ventilation. The surface design for clean room systems must be such that the expected particle emission is negligible. For laboratories G and custom-made products, corrosion attacks or the like can be significant for the choice of the surface material. In general, at least the side of the wall element facing the interior of the room is planked with steel, possibly with stainless steel. The structure is carried out in such a way that the

* ~ manufactured wandemeπte is set up by means of stems running between the floor and ceiling of the intended space, the stems forming the connecting elements between the wall elements that hold the wall. This means that the wall mountings are very expensive, especially

- ^■ - because the distances between the stems given by the

Wall elements with cover plates or the like must be closed. In order to obtain smooth wall surfaces ₉ , a special design of the edge areas of the wall elements so that the cover plates are also required

25 can be embedded "seamlessly". Such a design is particularly important if the room is designed as a clean room with a horizontally guided, low-turbulence displacement flow. In addition, due to acoustic or thermal requirements, below

30 different insulating walls are required, so that the wall thickness itself should be selectable according to the requirements. This means that the wall elements forming these walls have to be prefabricated, tailored to the need, which is also a considerable factor

~ - means additional manufacturing costs. This is where the invention begins, which is based on the object of proposing a construction of the wall element that enables the production of any wall thicknesses, that the insertion of a wide variety of intermediate layers permits, that has means with which the wall elements can be connected to one another at the end and thus production of the wall elements and assembly simplified and designed economically and that can also be used flexibly. In addition, fire-retardant wall elements should be proposed

And finally, walls formed from the wall elements should be proposed, which lead to rooms and room divisions and which, in addition, allow ventilated special rooms, such as "clean rooms", to be set up in a simple, uneconomical manner.

15th

This object is achieved according to the invention by the characterizing part of claim 1; Further developments and preferred embodiments describe the subclaims.

20th

The edge design of the cladding sheets of the wall element makes it possible to combine the cladding sheets with the locking rails to form a wall element. As is customary, reinforcements, fillers or the like are arranged between the panels. Since the

25 The choice of material for the cladding sheets is free, all possible metals from aluminum to stainless steel can be used depending on the purpose. All material requirements (insofar as they can be met by metallic materials) can thus be taken into account.

In particular, fire-retardant inlays can also be used, so that the wall elements can also be joined together to form fire-retardant walls. The special training of the wall elements also allows lines for energy supply or for media supply in a simple manner

35 supply between the shells of the planking. In this way it is possible to form installation walls which can even be built on the construction site "around the installations" by erecting one planking shell and erecting the installations on the outside connected, the stiffeners, fillings or the like are introduced, the other cladding shell is joined together in order to then close the wall element with the aid of the locking rails

Recesses and lead to a catch there. When joining the wandemeπte one can be lifted by the height necessary for hooking and joined to the other, the hooking being achieved after lowering. Another possibility is that one

10 of the locking slide is brought out of position by the height necessary for hooking and, after joining two wall elements, is brought into its end position by pressure or impact, the hooking taking place. The two locking rails of a wall element can only

15 recesses and those of the next wall element only have lugs; the two locking rails of a wall element can also be designed in such a way that one slide has the lugs and the other has the recesses.

20th

The arrangement of the noses leading to the interlocking and the corresponding slot-shaped recesses is expediently carried out in two or more rows running along the end face of the wall element, the number of rows

25 depend on the wall thickness and the number of nose / recess pairs on the height. Here again the decisive advantage of this structure becomes apparent: the cladding can be prefabricated regardless of the wall thickness; to set the desired wall thickness only

30 the appropriately deflected locking rails selected and used accordingly. The noses and the corresponding slot-shaped recesses can be at the same height, but a height offset is also conceivable. Due to the distribution of the noses and the slit

35-shaped recesses over the height of the locking rails, there is a uniform tightening over the entire height when caught, so that the front sides are pulled evenly against each other. The chen with Keilfl provided lugs are ^'in a position in which displacement relative to the recess er¬ considerable forces to be generated, which contract the so ge each coupled a wall elements. This allows spaces

5 me are created in which despite different

Air exchange is prevented due to pressure levels in different ventilation zones. If the joints between the wall elements are sealed, for example by means of interposed elastic sealing cords or sealing strips, they require a certain pressure, which is achieved in a simple manner by this design, in order to achieve the tightness that also meets the high requirements fulfilled, which are provided by clean room technology to such interior construction elements.

^'5 If the closure rail out picture as an integral element of the construction of the wall element in a particularly simple manner is possible; The specified planking and the necessary filling layers can be brought to the construction site separately, the necessary locking rails are cut to length and the wall elements - put together on the spot. With the einstücki

During manufacture, the recesses are punched out in a known manner. The protruding noses and possibly flags are punched out in the flat material and, after the edges have been rolled, pressed out at right angles to the surface, at right angles in the same direction as the edges. Here it is also possible to provide pressures in the folded edge strips at certain intervals, which frictionally lie against the edges of the cladding engaging behind and thus create a friction fit so that the locking rail is not yet in its position even when being transported assembled wall elements is held. Here it can also be realized in a simple manner that two locking rails of two adjacent wall elements have a height difference such that the lugs slide into the recesses when the wall elements are moved and then the locking rail is brought into its tightened position by pushing or hitting will. It goes without saying that, as a rule, each wall element has a locking rail with lugs and possibly flags and a locking rail with recesses. Exceptions. For example, when inserting stems into the wall, this is easily possible, since each wall element can be provided with nose locking rails or with recess locking rails on both sides.

To the dreaded in the case of one-sided thermal stress

To prevent bulging to one side, a type of closure rail, preferably the one provided with noses, is provided with transverse flags. These flags stabilize the locking rail in the desired manner. This stabilization is particularly effective when the

15 outer edges of the flags just touch the inner edge of the folds with their overlapping edges. It is therefore advisable to keep the width only slightly smaller than this width. Improved "beaking" when introducing the flags is achieved when the transition from the

20 front edge is rounded or beveled to the side edge. It goes without saying that - if the flags are to rest on the two edges between the fold and the rear engagement edge - they must not be led so far that there is an undesired setback in the area of these edges.

25 In special cases, it can be important if a locking rail with tabs and flags interacts with one that has corresponding recesses for the tabs and recesses for the flags. It goes without saying that the height of these runs transversely.

The recesses must be held in such a way that the locking rails have the necessary space to grip behind and tighten the wall elements. These stabilizations secure the connections of such wall elements against "bulging" if the wall elements, for example, designed as fire-retardant walls, are exposed to fire on one side. In order to be able to produce the convertible elements in a simple manner, spacer bridges are used near the edges, the open part of which faces outwards. Because of the locking rails, these spacer bridges do not need to be firmly connected to the paneling along the element sides closed with locking rails; gluing is sufficient. The other two spacer bridges at right angles to it are, however, made of nubs, projection welding or the like. connected to the planking, this connection preferably being in the non-visible area of a fold.

If an intermediate wall is provided in the interior of the wall element at a distance parallel to one of the paneling, can

15 a wall element can be formed which has an air gap. Such air gaps are good insulation, so that a fire-retardant wall element can be produced on this basis. The fire retardancy is improved if the partition wall facing the air gap

20 facing side has a coating which is inflatable under the action of heat. In addition, it is advantageous if the inserts are provided on the side of the wall element filled with inserts, which undergo a conversion when heat is supplied and this conversion consumes thermal energy.

25 needs. Such conversions are known in hydraulically bonded panels, such as cement fiber panels or plasterboard panels: When they are heated, the temperature rises to a stop point, further heat supply causes the expulsion of water from the crystal structure, whereby a dislocation

30 lengthening of the standing side of the fire-retardant component is achieved. Furthermore, it is advantageous if all the thermal bridges between the skins are designed in such a way that the greatest possible resistance is opposed to the flow of heat. This can expediently be done in that

35 the spacer bridges have a perforation, the perforated area being around 25% of the total area. In the case of the closure rails, the punched openings present there serve as such openings which hinder the flow of heat. However, additional openings can also be provided there. In order to achieve a tight seal of the component part in the case of fire-retardant components To achieve connections to one another, for example, the locking rails or the spacer bridges are provided with a coating that expands under the action of heat, so that the cavities in the joint area of two wall elements fill with inflated material in the event of fire and prevent the passage of fire gases.

Walls can now be assembled from these wall elements in a simple manner in which the hook-provided Ver¬

10 closing rail of one wall element is hooked into the closing rail of the other wall element, which is provided with the corresponding openings, and pulled together when the closing rail is moved. This shifting can also be done with devices, e.g. with hydraulic

• J5 directions are effected. The joining of the wall elements allows straight walls to be formed. For wall corners, T-shaped wall connections or wall crossings, posts with a rectangular cross-section are used in which two, three or four sides have slot-shaped recesses,

2o which correspond to the hooks of the locking rails and into which the locking rail hooks can be inserted. Exactly as with the connection of the wall elements to one another, the connection between the wall element and the stem is established, whereby - as already mentioned - wall elements can also be equipped with two locking rails provided with hooks. This is necessary at least in the case of a wall element abutting the stem. If handles are used in which two opposing walls have slit-shaped recesses for receiving locking rail

20 hooks, stems can also be placed inside straight walls. This is advantageous when wall elements of different heights are joined together, e.g. to insert windows or doors. If windows are used, the lower wall element is withdrawn to the extent that

35 that the lower edge of the window is at the desired height. Above the window, a further wall element is placed, the height of which is reduced to such an extent that its upper edge is flush with the upper edge of the adjacent wall elements. The same applies to the door, only the one under wall element is omitted here. The frames for the window to be used or for the door are customary, the window or door system ang 5 fitted frames, which are screwed to the stem or the locking rail of the adjacent wall element and in the usual means of the window frame with glazing or the door can be used.

10 Exposed walls can be created with the help of stems that are open on one side as a connecting comb. These connecting chambers have their own locking rails with hook attachments that can be guided through the recesses in the two opposing walls of the locking chambers. It goes without saying

15 of itself that the hooks of a locking rail of a wall element can also be inserted into these recesses and so the wall element can also be locked to the connecting chamber. A removable wall element can now be installed with the help of two connecting chambers so that the in

20 the connecting chambers have locking rails assigned to this wall element and hooks and the wall element is provided on both sides with locking rails which are provided with the slot-shaped recesses for receiving these hooks. When inserting the wall

25 element brought into position and the locking rails inserted into the connecting chamber, pushed with their hooks through the slot-shaped openings, the hooks also engaging behind the connecting rails of the wall element and finally the locking rail is locked by pressing

30 locks. To remove the wall element, the locking is released, the wall element is free and can be removed. It goes without saying that here the usual measures for sealing, such as between the wall elements and between the wall element and the connecting chamber.

35 follows. Another possibility for creating a removable wall element is offered by a locking mechanism with locking rails overlapping the wall joint on both sides, which can be moved by a locking rail drive in the plane of the planking and thus release the joint between two wall elements. The two fixed wall elements adjacent to a removable wall element are advantageously provided with these locking rails, which are brought into its closed position after the removable wall element has been inserted. The seals provided in the locking rails ensure the necessary tightness. To open the wall, the locking rails are withdrawn via the locking rail drive and the wall element that has become free can be removed. The locking rail drive is advantageously used distributed over the height, whereby a parallel movement of the locking rail is ensured. In this case, scissor gears are useful means for bringing about the movement of the locking rail from a common drive spindle. It goes without saying that, in addition to the manual drive of the spindle, hydraulic, pneumatic or other motorized drives are also possible and that the locking bar movement can also be carried out directly hydraulically, pneumatically or by motor.

In order to achieve a secure floor connection, a lower rail is attached to the floor, on which an upper rail is provided, with a seal, preferably provided with a lip, being arranged between the lower rail and the upper rail in the area of the side walls. To compensate for unevenness in the floor, the top rail is adjustable; it has spaced-apart adjusting screws which, in cooperation with a nut piece provided in the top rail, allow adjustment by supporting it on the bottom rail. A channel provided in the top rail is deeper than the head height of the adjusting screw; the depth of this channel defines the adjustment range. To set different bottom rail heights, different screw lengths are required, through which the bottom rail height is can be adapted if necessary without the adjustability of the floor rails being impaired. The underside of the wall elements are placed on the top rail of the floor rails and fastened there.

The ceiling termination is achieved by a ceiling termination rail which engages over the top of the wall elements, with lateral seals cooperating in a sealing manner with the outer sides of the paneling of the wall elements. The upper edge of the wall elements end below the inside of the ceiling end rails, so that it is possible to compensate for length tolerances of the wall elements or for thermal movements, which are already significant in the case of very long wall elements. To create "clean rooms" with vertical air flow, the ceiling rails are attached to the edge of the filter mounting profiles. For this purpose, the filter receiving profiles are provided with T-grooves on the underside into which sliding blocks are inserted; the ceiling rails are screwed to these sliding blocks, with interposed seals ensuring the tightness. The filter receiving profiles themselves are suspended from the existing building ceiling, they are provided with sealing channels in which viscous or liquefiable and solidifying sealing compounds are provided, into which the sealing collars of the filter cells are sealingly immersed. These filter mounting profiles form a grid stretched across the ceiling, the free openings of this grid corresponding to the size of the filter cells. Each filter cell (or group of filter cells) is supplied with air via a hood and a connection to a ventilation line. If the filter cells are to be jointly supplied with air, a pressure chamber is created above the filter ceiling. For this purpose, a profile corresponding to the bottom rail is screwed tightly onto the edge filter mounting profiles and wall elements are placed at the required height to form a pressure chamber above the filter ceiling and are tightly connected to the building ceiling. The supply air is then supplied via this pressure chamber. The essence of the invention is explained in more detail with reference to the attached FIGS. 1 to 15 with reference to exemplary embodiments. Show it

1 shows a frontal section from a wall element lo with the two-sided paneling 11 between which the reinforcement, insulation or the like 12 indicated in layers is arranged. In the area of the end face, the planking 11 is folded inwards so that a fold is formed

11.1 results, which in turn is provided in a rear engagement strip 11.2 pointing inward at an acute angle. The two panels are held together by the locking rail 14.2, which is behind the rear engagement strip 11.2 with their corresponding to the position of the rear engagement strips

11.2 bent edge strip 15 engages. The Verschluß¬ rail 14.2 is provided with slot-shaped recesses 18 ₃ which cooperate with the locking hook 16 (Fig. 2) so allow the joining of the Wandelemnte. In addition, transverse slot-shaped recesses 18.1 can be provided which receive the transverse lugs 17 (FIG. 2) and serve for transverse stiffening, the width of the slot-shaped recesses 18.1 essentially corresponding exactly to the width of the exposed sheet metal lugs 17. As a result, a form fit that acts on the sides and prevents bulging is provided. The intermediate layers 12 which stiffen the wall element can be molded foam inserts, they can be panels based on mineral fibers, but they can also be stuffed mineral fibers, this depends on the requirements that are placed on the wall element itself.

FIG. 2, which corresponds to FIG. 1, shows the corresponding end face of a wall element in which the planking 11 is closed with the locking rail 14.1 provided with lugs 16. These lugs 16 hook into the slot shaped recesses 18 of the other locking rail 14.2 (both Fig. 1), this allows the interlocking of wall elements joined together without intermediate stems. In addition, exposed flags 17 are seen, for example, as sheet metal flags, which reinforce the locking rail in the transverse direction and thus counteract any bulging, for example in the event of a fire. These tags 17 can cooperate between the bent-over 11.1 and Hin¬ tergreifungsleiste 11.2 or (in special cases correspond ^ö the length of the lugs 17) with recesses 17, wherein a directed to both sides "positive locking" is advantageous with the inner edges of each.

3 shows a detail of the interaction of the

15 on the lugs 16 provided on a closure rail 14.1 with the slot-shaped recesses 18 in the corresponding rail 14.2. After hanging the wall element or after moving one of the two locking rails 14.1 or 14.2, the projection 16.3 engages behind the boundary - the slot-shaped recess 18, the inclined surface 16.2 provided on it exerting a closing force as a wedge such that the two locking rails 14.1 and 14.2 are drawn against each other. It goes without saying that the height of the slot-shaped recess 18 is at least the

25 must have the same size as the height of the nose 16 including its projection 16.3. It goes without saying that this is the case for the height of a slot-shaped recess 18.1 into which an exposed flag 18 can engage and which is designed as a transverse slot

30 applies in the same way: Its height is to be dimensioned so that it gives the sheet metal flag 18 sufficient space for its movement, which is necessary for "hooking" both locking rails.

Finally, FIG. 4 shows ab¬ along the center line

35 broken and staggered cross-section in the position as indicated by yy in FIGS. 7a and 7b, cross-section through two wall elements 10 connected to one another in itself stiffened closed. To do this, the locking rails hook

14.1 or 14.2 with their bent edge strips 15 behind the inwardly directed rear engagement edges 11.2, which are formed by the edging of the cladding sheets 11 and adjoin the respective fold 11.1. The noses 16 provided on the closure rail 14.1 and arranged in two vertical rows at different heights - shown in section in the lower half of the figure - engage in the slot-shaped recesses 18 in which

10 they get caught. When caught, the inclined surface slide

16.2 (FIG. 3) onto the lower edge of the slot-shaped recesses 18 (FIG. 3) and pull the two locking rails 14.1 and 14.2 against one another. As a result, both Wandele¬ elements 10 are drawn against each other, the respective

15 folds 11.1 of the one against the corresponding fold 11.1 of the other wall element 10, wherein the gap is sealed with an interposed sealing tape 11.3. In the right-hand part of FIG. 4, the opening 16.1 created by the punching free of the bent nose 16 can also be seen.

The locking rail is also provided with the outwardly pointing stiffening flag 17, which also. is exposed from the locking rail by punching and bending. As can be seen in the upper part of FIG. 4, the noses are advantageously offset in height,

25 the next nose 16 'of the second vertical row is located at a distance below the cut and exposed flag 17.

To secure the connection between the two panels

30 11 of a wall element 10 through the closure rail 14.1 or 14.2, the bent edge strips 15 are provided with pressures 15.1 which force a frictional engagement with the inwardly directed engagement edges 11.2. In the lower part of FIG. 4, the locking rails 14.1 or

35 14.2 cut outside of the impressions 15.1, in the upper part of the figure in the area of the impression, which is preferred wise located at the level of the outward-facing flag 17. These lugs 17 themselves have rounded (or beveled) transitions from the front edge to the side edge to facilitate insertion. The width of the flag 17 is so sweet that it fills the clear space between the inwardly directed edges 11.1 of the cladding 11.

5 show another embodiment of the edge areas

1.0 of the wall elements 10: In the area of the wall element edges, spacer bridges 19 are provided which fill the clear space between the panels 11. The inserts 12 are withdrawn by the corresponding depth of the spacer bridge 19. In the area of the wall provided with locking rails 14.2

15 element edges (FIG. 5a), the spacer bridges formed as C-shaped profiles are only connected to the planking 11 with adhesive inserts 19.3. The P- ~ H inwardly directed folds 19.1 are free. The locking rail 14.2 engages in the manner described above with its bent-over edge strip

20 15 behind the rear engagement strips 11.2, which were created by the above-described shaping of the planking edges. The spacer bridges in the area of the edges running at right angles to the wall element edges closed with the locking rails 14 are designed so that the ab¬

25 stand bridges with their inwardly directed bends rest against the inwardly directed bend 11.1 of the cladding II and mechanically with the cladding by means of nubs

19.2 or the like. are connected. Adhesive securing can also be used here

19.3 should be provided because of the mechanical connection

30 19.2 essentially serve to facilitate assembly.

6 shows an edge design of the wall elements 10 as fire-retardant wall elements 10.3: Here the panels 11 are spaced apart in the manner described above

35 bridges 19 kept at a distance from one another. To reduce the heat transfer, humps ^' 19.4 are provided in the spacer bridges, which can be glued to the insides of the Sheeting 11 are fixed. Furthermore, at a distance from the cladding 11 from which a fire effect is to be expected, an intermediate wall 13 is introduced, which runs parallel to the cladding 11 and at a distance from it. This partition is secured in position with angles 13.2, which in turn are provided on the spacer bridges 19, and these partition walls 13 are further provided with a coating 13.1 made of a material that inflates under the action of heat and the insulating air gap

TO between the intermediate wall 13 and the cladding side 11 corresponding thereto. To reduce the cross section available for heat conduction, AusstaVizungen 19.5 are provided in the spacer bridges, the free area of which reduces the remaining area to about 75%.

15 of the total area reduced. The cross section available for heat conduction is reduced to the same extent. In addition, the locking slide 14 - here the locking slide 14.1 is drawn with lugs 1.6 - are provided with a coating 13.1 made of a layer under the action of heat

20 provided inflating material that fills the space between the locking slides and thus the joint between the two wall elements 10.3. As a result, the joint is hermetically sealed; in addition, the inflating masses generate a force that supports the closing effect,

Z5 so that there is no risk of the joint opening under the action of fire.

FIGS. 7 show locking rails in one-piece design as a section, with FIG. 7a showing the one with lugs

30 16 provided closure rail 14.1 and FIG. 7b, which relates to the closure rail 14.2 provided with these lugs 16 receiving recesses 18. Sideways to the. The edge strips 15 are molded onto the green area of the profile forming the closure rail 14, with the edges engaging behind

35 11.2 (Fig. 1,2) interact. The lugs 16 are formed by punching and flaring out, so that corresponding openings 16.1 remain in the base material. The punched-free noses 16 are set up at right angles to the surface of the base material and point in the same direction as

ERSAT2ΘLA7T the bent-over edge strips 15. In the case of a two-row design, the noses are arranged alternately on the left and right edge of the closure rail. It should be understood that multi-row arrays are possible, especially ⁵ when the thickness of the wall elements so requires. Then the noses are arranged in a corresponding pitch over the height, for example in the case of a locking rail with 4 noses the noses of the two outer rows of noses and the two noses of the inner rows of noses each at the same height. Between two on

'"^" Noses (or pairs of noses) arranged at different heights are set up transversely running flags 17, which are also formed by punching and leave an opening 17.1 and which are brought into position by being set up at right angles. In the area of the raised flags 17 are the 5 pressures 15.1, which interact with the rear engagement edges 11.2 (FIG. 4) and which secure the position of the locking rail through increased frictional engagement. The protrusion of expression 15.1 can be seen in section xx (lower illustration). The lugs 16 themselves have projections 16.3 0, the rear side of which facing the locking rail 14 is designed as an inclined surface 16.2 which, running onto the edge of the recess 8 of the recessing locking rail 14.2, generate the force to pull the wall elements together. The drawn section yy clarifies the cutting line of FIG. 4, the nose 16 in the area of the undisturbed, bent edge strip (top) and the pressure 15.1 at the level of the flag 17 punched out of the one-piece locking rail and exposed in section. The ver¬ with the recesses 18

30 see locking rail 14.2 (Fig. 7b) corresponds to the locking rail 14.1 provided with the lugs 16, so that lugs 16 and recesses 18 over the _. match the entire length of the locking bar. The section in FIG. 4 is also illustrated here by yy and so ge

35 selects that the recess 18 is cut in the area of the undisturbed and bent edge strip 15, while the pressure 15.1 is at a height as shown in FIG. 7a. represents is cut. A recess 18.1 is shown in dashed lines, which would be necessary if the punched and exposed flag were to protrude through the other locking rail into the interior of the adjacent wall element.

The wall elements formed in this way are in themselves held together by the locking rails 14, but they are also connected to one another by the locking rails 14. the

The design is such that the cladding 11, the filler layers 12 to be inserted between the cladding 11 and the locking rails 14 do not have to be preassembled. This considerably simplifies storage and facilitates planning changes that can be carried out on the spot. ^'5 It can also be the planking material that can be stored as a sheet material and cut to size, be¬ chosen arbitrarily and are thus not yet changed, the edge construction is done by simple edges. The wall elements can then be joined together

20 den. These wall elements are simply joined together at the installation site. Since they fit one another (almost) seamlessly, walls are produced with almost no joints when assembly is simplified.

"7 ~ Figures 8 show the possibility of joining the wall elements 10 together by means of interposed posts. The wall elements 10 are provided on the side facing the post 41 with locking rails 14.1 provided with lugs 16, which fit into the outlines corresponding to the lugs 16.

~ * ~ recesses 42.1 of the stems 41 fit and are hooked with them in the manner described above. Stems 41.1 provided with recesses 42.1 on both sides can be used to form straight walls. The corner connection with posts 41.2 is more important than this wall connection

35 which two sides standing at right angles to one another are provided with the recesses for the noses. By inserting the wall elements 10 as described above a corner of the room in which the wall elements 10 meet at an angle of 90 ° (Fig. 8b). Room subdivisions require a style element 41.3 provided with recesses on three sides, so that a continuous wall, formed from wall elements 10 with a wall standing up at right angles, is formed from

Wall elements 10 can be assembled (Fig. 8c). Finally, FIG. 8d shows a crossing of two walls formed from wall elements 10, the stem element 41.4 here being provided on all four sides with recesses that receive the noses of the locking rails. These connections are possible because the wall elements 10 can also be provided with locking rails 14.1 with lugs 16 on both sides, so that in all cases there is the possibility of having "lug locking rails" on the side facing the stem. In connection with the partition wall according to FIG. 8c, the usefulness of the double-sided wall post 41.1 according to FIG Handle 41.1 according to FIG. 8a provides the necessary compensation so that wall elements of the same width can be used. A detail of a stem 41.3 with three connection sides 42 is shown in FIG. 8e. Here the three connection sides 42 are provided with (indicated) recesses 42.1 for inserting the seam. In order to be able to connect wall elements of unequal thickness to one another, the stems are used in accordance with the requirements for the greater wall thickness; the abutting walls of lesser thickness are set in place with compensating pieces 45, or on one side with a correspondingly larger compensating piece 44. So it all succeeds

To be able to create configurations of walls with prefabricated and easy-to-assemble elements.

In interior construction, in particular partition walls "clean rooms", the problem often arises that wall parts must be designed to be removable. This is due to the fact that access to the rooms is via people or material locks the replacement of built-in machines for overhaul or repair is not permitted due to the dimensions and that dismantling of these machines cannot be tolerated in the "clean room". Removable wall elements now allow machines of even large dimensions to be exchanged in a simple manner, without excessive loading of the "clean room" through dismantling work. For this purpose, open connecting elements 46 according to FIG. 9a can be used, which are provided with recesses 46.1 for pushing through one provided with lugs 47.1

TO special locking rail 47 according to Fig. 9b provided. In this case, the sides of the wall elements facing the connecting chamber 16 are provided with locking rails which have recesses for the lugs to pass through. The locking chamber 46 shown in Fig. 9a is in four vertical

T5 rows of recesses provided for a locking rail with lugs also in four vertical rows. The locking rail according to FIG. 9b has only vertical rows of lugs; it goes without saying that a corresponding connecting chamber (not shown) can be used for this purpose and that a corresponding locking rail (not shown) has four vertical rows of lugs is also possible. To move the locking rail 47 in the longitudinal direction, an attachment angle 47.2 is used, on which the force necessary for moving and thus for pulling the wall elements together can be exerted by hitting or pressing. This is shown in FIG. 10 using the example of a connection between a stationary wall element 10 and a removable wall element 10.1. The mutually facing sides of the wall element have planking 110 which, in the case of the fixed wall element, also includes the connecting chamber 46. The spacer bridge 19 and on one side the planking 11 are withdrawn so far that the spacing chamber 46 can be interposed and the planking 11 '"engages behind" the connecting chamber 46. The used. 5 locking rail 47 holds the removable wall element 10.1, whose edge formation with the spacer bridge 19 in the previous written manner is carried out. The closure chamber 46 is closed with a cover strip 47.3. In the sectional illustration drawn out above the figure, it can be seen how the nose 47.1 engages behind the locking rail 14.2 provided with recesses for receiving the noses and thereby penetrates the recesses 46.1 in the wall of the connecting chamber 46. By longitudinal movement in the direction of the hook of the nose 47.1, the connecting chamber 46 and the removable wall element 10.1 are locked to one another in the manner described above. In this illustration, a connecting chamber 46 is shown, which is provided with four vertical rows of recesses 46.1 for the passage of noses. The locking rail 47 cooperating with it, on the other hand, has two vertical rows of noses 47.1. It goes without saying that the wall element joint and the fold lying on the connecting chamber 46 are sealed with appropriate sealing means, the fold lying on the connecting chamber 46 being pressed against a sealing cord inserted in a receiving channel.

Another solution for a removable wall element shown in FIGS 11. Here is a sealing strip 51 is provided, the management on both sides over the entire height of an impact between a fixed wall element 10 and a removable Wandele- ^"is performed 10.1. This sealing performance can the fixed wall element can be withdrawn, for which purpose a locking rail drive 52 is provided, which can be driven from the outside via a drive shaft 52.2 In the example shown, several individual drives 52 distributed over the height of the wall element 10 are shown, which drive via a common spindle

52.1 must be actuated. This is shown in cross section in FIG. 11b closed in the upper part and open in the lower part. The fixed wall element 10, which is provided with the locking device, strikes the removable wall element 10.1 at a distance; seals on the planking of both wall elements. To remove the removable wall element 10.1, the drive spindle 52.1 is actuated via the drive shaft 52.2, which in turn drives the jack-like scissors 52 so that - as shown in the example below - the locking rail 51 is pulled back until the removable wall element 51 is free and can be removed. It goes without saying that such a closure device is provided on each side of the removable wall element 10.1 (or the removable wall elements).

Fig. 12 shows schematically the structure of a wall of a "clean room" with downdraft air flow. The wall elements 10 (shown interrupted) form the wall surface, the wall elements 10 being arranged on a floor rail 20. This floor rail 20 consists of a lower rail 21 which is fastened in the building floor with dowel screws 22, for example. The lower rail 21 is overlapped by an upper rail 23, with seals 25 arranged on both sides between the lower rail 21 and the upper rail 23 ensuring a seal between the upper rail and the lower rail. An adjusting screw 24 supported on the lower rail cooperates with a threaded insert 24.1 and allows the upper rail to be aligned so that unevenness in the floor can be leveled out. If, in addition, height differences that are greater than the adjustment range of the adjusting screw 24 are to be compensated for, adjusting screws of different lengths are used. The wall element 10 is set up on the upper rail 23, with appropriate seals 23.1 in between is. Spacer bridges keep the cladding at the desired distance from each other on all four sides. The upper edge of the wall element is overlapped by the ceiling rail 31, which in turn is provided with seals 32 resting against the skins 11 and forms a tight seal. The wall element 10 sits with sufficient play in the ceiling closure rail 31 so that the ceiling closure rail does not rest on the wall element. The wall elements 10 are furthermore decoupled from the ceiling structure by the laterally attached seals 32. The ceiling structure is formed by suspended filter receiving profiles 35 which are fastened to corresponding suspension irons 37. This Filterauf¬

1.0 acquisition profiles form a grid corresponding to the dimensions of the filter cell 36, the seal between the filter cell 36 and the filter receiving profile 35 being effected by a sealing collar 36.1 provided on the filter cell 36 dipping into sealing grooves 35.1. These sealing gutters are well known

15 way filled with viscous liquids or solidifying and remeltable masses, so that a good seal can be made. The height of the sealing collar 36.1 is less than the depth of the sealing groove 35.1, so that the filter cell 36 is on the edge of the sealing groove and thus on

20 is supported on the filter receiving profile 35. In the embodiment shown, each filter cell 36 has its supply air hood 36.2, which is provided with a connector 36.3, which in turn is connected to the corresponding central supply air line (not shown in detail). To the outside is

25 the ceiling profile including the gap up to the hall ceiling is closed with a cover 38 which engages with a hook leg in the sealing groove 35.1 without having to seal there and which is supported against the wall element 10 with an inserted seal 38.1 , making yourself

30 the Hal erung for the aperture 38 results.

In FIG. 13, a variation is shown which relates to the formation of the ceiling termination. Here the filter receiving profile 35 is screwed onto a

35 put wall panel 10 connected, which extends to the building ceiling and which forms a circumferential pressure chamber. As a result, there are no additional ones for the individual filter cells 36 Supply air hoods 36.2 (Fig. 12) are required, since the supply air enters the pressure area enclosed by the upper wall elements 10.

. chamber, which is sealed up by the floor ceiling, is blown. 5

The design of the wall elements 10 also allows wall elements of different heights to be joined together accordingly. This allows in a simple manner - as shown in Fig. 14a - the insertion of windows and doors in interior ° walls. To insert a window, for example, a low-height wall element is inserted between two posts 41, if necessary, so that the upper edge is at the desired height of the frame for the window. Inserted rail pieces 23 corresponding to the upper rail closes the wall element at the top, another wall element attached from above extends to the intended upper edge of the frame and is closed off by a further piece of upper rail 23. The frame for receiving the frame of the window 54 is inserted into the space and fastened accordingly. It goes without saying that the interposition of stems is not absolutely necessary; As FIG. 14b shows, the frames for receiving the windows or the window frames 56 can be connected directly with screws 56.1 to the wall elements 10 which have closure rails 14.2 without lugs on this joint side. The door 55 is inserted in a similar manner, although the bottom rail 20 is interrupted in the area of the door leaf and the door leaf is provided with a seal 55.1 that rests on the bottom in the closed state. It is particularly advantageous to design the walls with spacer bridges for insertable installation walls; here the spacer bridges are used as installation supports 59, which receive and support the lines or the bushings of the installation lines. In the example shown, a water supply 57 is connected via a screw connection 57.1 to the inner wall element installation, which also has an emergency shower 57.2, which can be seen via a quick-acting valve 57.3. The other supply is a gas or compressed air supply supply 58, which is connected to the inner wall installation with screw connection 58.1. In this type, it is possible to prefabricate the Installationsele ducks so that after installing the wall element, only the fittings must be attached to the outlet side and the connection with the supply must be made. In order to keep the installation accessible, an opening is provided on the outside of the installation wall element, which can be closed with a closure plate - not shown . Can be locked with quick-release fasteners. The wall elements themselves are held in the bottom rail 20 with bottom rail 21 and top rail 22 and the ceiling rail 31; it goes without saying that the ventilation equipment, not shown in detail, can also be provided in accordance with FIGS. 12 and 13.
