EP0735209A1 - Cross or longitudinal supporting section for a ceiling covering - Google Patents

Abstract

The main body (21) is in one piece, having a double-walled web (21a), onto which a double-walled upright (21b) joins at right angles. A sheet-metal strip (210) is bent to form horizontal outer and inner strips bearing against each other and two upright strips also bearing against each other. The web is enclosed by the stiffening part (22) formed from a second strip (220) bent round it. The parallel edges of the first strip form the free edge of the upright, while those of the second strip are at opposite sides, between the web and the upright. The edges of the first strip can be bent outwards to form grooves for holders securing the cladding panels. The groove can be of semicircular cross-section.

Description

The invention relates to longitudinal or transverse beams for a support structure, which are formed essentially from T-shaped, angled sheets, for a ceiling cladding from adjacent, forming a surface grid and each insertable between two parallel beams and detachably held on these ceiling plates.

Such inlay constructions are known, for example, from the company publication "Konstruktion 200" from Suckow + Fischer GmbH, where they are designed for holding ceiling panels made of plaster, metal, pressed wood shavings and the like, which on the cross straps of longitudinal and cross members clear dimensions between their webs are just filling, laid on.

It goes without saying that the folded profiles should not overlap the webs as much as possible, so that the width of the ceiling plates that can be used is used Cross belts are not unnecessarily restricted. The folds from the level of the webs are therefore equally wide on each side, so that the web edge at the zenith of the folded profile is exactly in the center; this is necessary at least for the beams if the insert construction is hung there on the folding profiles, the suspensions being introduced into the interior of the respective folding profile through the gap. The central arrangement of the zenith on the support profile ensures that no torques can attack the supports.

Because the connecting straps for integrating the cross-members into the beams at least partially overlap the folding profiles and thereby narrow the clear widths for the ceiling panels in the area of these folding profiles, so that the cross-belts have to be made considerably wider in order to ensure that the ceiling panels are securely supported, In DE utility model 94 13 816 a reverse T-shaped, beveled profile has been proposed for the wearer, which has only an eyelet-like, narrow widening of the upper part serving as a holder, a suspension being insertable into suitable slots of this part. This results in a relatively light design of the insert construction, the dimensioning of which can be carried out solely from a static point of view, while the structural design of the insert construction plays no or at least a minor role. However, the required folding profiles are relatively complicated and require a large number of folding, sometimes in the immediate vicinity of one another. Above all, however, determine the ones below Straps Shape and size of the surface grid visible from the room.

In contrast, the invention has set itself the task of executing a carrier of the type described in more detail above for a holding structure with components that are easy to manufacture, in which the grid joints of the surface grid can be kept very narrow and instead are formed by the ceiling plates themselves instead of the carrier are to be individually assembled and disassembled and which can form a variable grid, at least between very dimensionally stable beams. The entire carrier should largely do without machining and integral connections in order to maintain an, for example, galvanic coating of its components intact.

According to the invention, the object is first achieved in that the supports each consist of a T-shaped base sheet metal body and a stiffening sheet metal body, the base sheet metal body in one piece from a T-shape forming double-walled belt and a double-walled adjoining it The web and the web are angled from a single first sheet metal strip to form a (horizontal) adjacent outer and two inner web strips and two (vertical) adjacent web strips, the belt is encased by the stiffening sheet metal body and the stiffening sheet metal body is composed of a single, sheet metal angled to form the belt, the parallel edges of the first sheet metal strip together the free edge of the web form and the parallel edges of the second sheet metal strip are in the double-sided longitudinal gussets between the web and the belt.

Such a carrier can be produced without difficulty from a galvanically coated sheet of metal, without the coating having to be locally damaged by punched-out perforations or spot welds or other defects. The strap of the carrier can be produced by the applied stiffening sheet metal body with a particularly high proportion of the total moment of resistance of the carrier and at the same time is already extremely dimensionally stable on its own.

The invention is further characterized in that the edges of the first sheet metal strip are angled toward horizontal first guide grooves pointing away from the web, in which guide pieces for the ceiling panels which are displaceable along the support are guided. In this way, the prerequisite has been created for the ceiling panels and all other components of the holding structure connected to the supports to be able to be connected without having to be screwed or welded to the supports, so that they are actually no longer galvanized after they have been completely produced must, but can be made according to the task from already appropriately coated metal sheets.

It is advantageous if the guide grooves have a semicircular cross section, because this can be easily shaped and enables the holding pieces to be guided reliably without them being able to clamp on the supports. Another management of the holding pieces is created by the fact that the edges of the second sheet metal strip each end at a distance from the web and the holding pieces are guided in the second guide grooves formed in this way on both sides of the web and adjoining the belt and each delimited by one of the edges and the web. In this way, they can be moved along their carrier as desired and brought into a position in which a component is to be connected to the carrier. This makes the straps extremely versatile, without the straps having to be adjusted in each case. Rather, carriers of the same length can be made together and kept in stock; they can be adapted to the local conditions during assembly to the complete support structure without the need for further special processing.

The holding pieces suitably each consist of a flat piece of sheet metal and at least one holding element fastened to the sheet piece for the associated ceiling plate; the holding element can also be releasably attached to the sheet metal piece. The generally flat piece of sheet metal remains in place when the component connected to it is installed, without it having to be connected to the carrier other than via the two guide grooves.

The entire arrangement of the holding structure is extremely dimensionally stable if the ceiling plate can be positively connected to the holding element; for this purpose, the holding element can be designed in the form of a bolt and protrude into the spatial area of the associated ceiling plate. It goes without saying that this ceiling plate must have corresponding recesses or other shaped elements which correspond to the holding element in a form-fitting manner. Such connections are possible in a variety of designs; It is particularly advantageous if they can be easily detached by changing the position of the components involved, so that the ceiling plate can be removed comfortably from the holding structure. The details of such connections are common in the art.

In addition to the ceiling panels, cross members, for example, can still be easily connected to the side members; for this purpose, tab pieces can be guided in the same guide grooves as for the holding pieces, to which cross members of this type can be connected, which are then clamped between the beams. Cross members may be required if the clear width of the ceiling panels turns out to be too large, in particular also if, as will be explained below, the carriers are provided in a reverse T-shape with overlying ceiling panels, as is known from DE utility model 94 13 816 is.

The ceiling panels can each be angled from a sheet metal blank, in particular in such a way that they each consist of a flat, horizontal, preferably rectangular surface piece facing the room, coordinated with the surface grid, and edge pieces angled at all angles in the area of the supports; the ceiling panels are particularly dimensionally stable if the edge pieces are joined together at their abutting edges.

The area grid is therefore formed by the surface pieces of the ceiling panels, especially if they end below the beams, while the edge pieces can also be used for locking. The ceiling panels are box-shaped and can, if necessary still be filled with insulating material; As a rule, however, a later coating of the surface pieces is sufficient, for example to design an acoustic ceiling.

The supports according to the invention are particularly advantageous if flanges are formed on the ceiling panels at their edge pieces running transversely to the supports, preferably in one piece with them, and are designed such that they can be placed on top of one another and one of the abutting ceiling panels is supported on the one hand on another, adjacent one and on the other hand supports a third neighboring one. Such an arrangement makes it possible to dispense with crossbeams: the ceiling panels are nevertheless securely supported because they rest on three sides. The stability on its fourth side, which supports the adjacent ceiling panel, can be improved in that the ceiling panel on this side is supported on the adjacent supports by at least one holding piece on both sides.

A uniform joint width between the ceiling tiles results in a simple manner if the flanged edge pieces of adjacent ceiling tiles strike on both sides of a spacer attached to at least one of the associated beams, for which it is also sufficient if it is only temporarily and provisionally provided and even with the beam has not been firmly connected.

The mutual support of the ceiling panels is possible in that the flanges are formed as continuous, flat sheet metal tabs on the edge pieces, which in the same in the case of abutting edge pieces Show direction. A ceiling tile lies on an adjacent one, but can be lifted upwards. Therefore, the arrangement of a ceiling plate on the holding piece can be made such that the ceiling plate is pivotable about the holding elements located on the sheet metal pieces of these holding pieces.

The described design of the carrier is primarily intended for a holding structure in which the straps of the carrier are oriented overhead. It is, however, deviating from this, as with the previously known holding structure, that the carriers are arranged so that their belts serve as a support for the ceiling panels. With such an arrangement, a suspension of the carriers can be carried out very easily by providing openings, such as slots or the like, in the webs of the carriers, in which suspensions can be locked for the carriers. It is particularly favorable if the suspensions run into flat retaining tabs that can be inserted into the double-walled web of the respective carrier and are provided with integrally molded spring pieces that engage in the openings so that they fix the carrier in the process.

With such a suspension, it is sufficient to slightly splic the two web strips of the upwardly pointing web of a carrier and to insert the respective retaining tab into the web so far that its spring piece engages in one of the openings provided there and the suspension latches with the carrier. A slight bulging of the web at this point can easily be taken into account when designing the guidance of the holding pieces and / or tab pieces in such a way that they have enough play in the guide grooves to prevent jamming on the bulges; It is also useful to selectively place the holding pieces and / or tab pieces on the webs instead of flat. In addition, the sheet metal pieces of the holding pieces are usually spaced sufficiently far from the web because of the special design of the guide grooves.

A support structure with beams according to the invention leads to a very light construction, which also reduces the overall load on the ceiling.

In any case, the design and the rational production of the carriers are of great importance.

A carrier of this type, which consists of a T-shape, a single, double-walled, angled first sheet metal strip, each with a horizontal belt and a perpendicular web that adjoins this at right angles, and a basic sheet metal body that covers the belt on both sides, on the other Belt strips each flat stiffening sheet metal body consists of a single, the belt angled to form a second sheet metal strip, wherein the parallel edges of the first sheet metal strip together form the free edge of the web and the parallel edges of the second sheet metal strip in the double-sided longitudinal gussets between the web and the belt, can be produced according to the invention in that the base sheet metal body is first produced from the first sheet metal strip in such a way that the two inner belt strips adjoining the web, of the double-walled belt only so far from the outer belt strip and de n web strips are angled, that the web strips form an acute angle with each other in contact with the edges and the inner belt strips with the outer belt strip, and that the second sheet metal strip is then formed over the belt in such a way that the stiffening sheet metal body formed thereby with its inner ones abutting the inner belt strips Edge pieces are angled through 180 ° from the sheet metal strip lying against the outer belt strip so that the inner ones lie flat against one another on the outer belt strip and the web strips.

As a result, the base plate body is not initially brought into its final shape; this takes place only through the stiffening sheet metal body deformed above it, so that the superimposed surfaces of both sheet metal bodies are braced against one another under considerable pretension and in this way ensure a stiffening sheet metal body which is extremely firmly attached to the base sheet metal body, even when the remaining The elasticity of the sheet used is not high. The base sheet metal body of the carrier thus also receives its final shape only after it has been connected to the stiffening sheet metal body. Since, overall, only a few folding processes are required and the folds on the carrier are relatively far apart, such a carrier can now be produced very efficiently and precisely from two simple sheet metal blanks; especially in the case of the holding structures according to the invention, there is no longer any aftertreatment and a galvanic coating can, if necessary, already be provided on the two metal strips.

all in a schematically simplified representation.

A carrier according to the invention is used to hold ceiling panels 1 (1 ', 1''), which are inserted according to FIG. 1 into an area grid R and are held according to FIGS. 2 and 3 on carriers 2, which are parallel to each other from a room wall to others are sufficient and are either attached to the ceiling above or attached to the walls of the room. Very narrow grid joints F are formed between the ceiling panels 1, the joint width b of which depends along the support 2 on the construction of the support 2 to be described and transversely for this purpose from spacers D (FIG. 3), which are provided on the supports 2, at least temporarily.

In Fig. 4 it can be clearly seen that the ceiling panels 1 (1 ') are box-shaped by angled on a flat, the surface pattern R defining surface piece 11 on all sides edge pieces 12 and the height h (Fig. 4) determine the respective ceiling tile 1. In this case, two end edge pieces 12a are provided for holding the ceiling plate 1 on the two supports 2, between which the ceiling plate 1 is clamped, while the longitudinal edge pieces 12b and 12c 'provide mutual support for two adjacent, abutting ceiling plates 1, 1' (Fig 4) serve. The reference numerals of the rear ceiling plate in FIG. 4 are noted for a better differentiation.

The details of the carrier 2 can be seen particularly well in FIGS. 2 and 4 to 6. It consists of formed sheet metal strips 210 and 220 in a composite construction of a base sheet metal body 21 and a stiffening sheet metal body 22.

A first sheet metal strip 210 is angled several times to form a double-walled belt 21a and a web 21b which is also integral and also double-walled on the belt 21a, the belt 21a and the web 21b being initially preformed in accordance with FIG. 5 such that those directed towards the web 21b inner belt strips 21a, i with the outer belt strips 21a, ä forming the upper end of the sheet metal base body 21 each include an acute angle w1 and the web strips 21b, s enclose an acute angle w2.

The base sheet metal body 21 is angled such that the free edges 210a of the first sheet metal strip 210 end at the end of the web 21b facing away from the belt 21a and run parallel to one another. They are each formed into a semicircular cross-section HK which is open at the top, so that a first guide groove N1 is formed on each side of the web 21b. 5 that the guide grooves N1 are used for parallel, parallel guidance on the support 2 of a holding piece 3 to which a ceiling plate 1 can be attached. Such a holding piece 3 consists of a flat piece of sheet metal 31, to which a holding element 32, which projects into the spatial area of the ceiling plate 1 to be held, is fastened. The sheet metal piece 31, which is rectangular here, the lower edge 31a of which slides in the guide groove N1, is likewise mounted with its upper edge 31b movably along the support 2 in a second guide groove N2. The second guide groove N2 arises from the fact that the edges 220a of the second sheet metal strip 220 do not extend to the web strips 21b, s of the web 21b, so that the guide grooves N2 each have an edge 220a, a web strip 21b, s and an inner belt strip 21a , i are limited. It goes without saying that it is expedient to arrange the holding piece 3 with clearance in the guide of the guide grooves N1, N2, so that they can be introduced into the guide without difficulty.

The second sheet metal strip 220 is angled toward the stiffening sheet metal body 22, as is particularly illustrated in FIG. 5. The initially provisional bending of the base sheet metal body 21 with the angles w1 and w2 is brought into the final shape by the application of the stiffening sheet metal body 22, in which the Angles w1 and w2 disappear. The edges 220a press the longitudinal gusset to its permanent 90 ° shape.

In Fig. 2 and 4, the holding elements 32 are shown as bolts which each reach into a hole punched in the side wall of the plate and rotatably support the plate so that it can be swung down from the ceiling level and inspection openings for Uncover ceiling void. Other connecting parts or connecting elements instead of the holding element 32 are also possible, a positive engagement always being to take place. However, it is expedient if the positive connection can be released in the event that the relevant ceiling plate 1 is to be removed from the holding structure.

Cross beams between the longitudinal beams 2 for supporting the ceiling panels are usually superfluous in a support structure according to the invention. Instead, a flange 12d, 12e 'is angled at each of the adjacent edge pieces 12b, 12c' (FIG. 4), in such a way that they point in the same direction and lie flat on one another when the ceiling panels 1,1 'are mounted, the support flange 12e 'rests on the support flange 12d, in the vicinity of which the ceiling plate 1 rests on the holding elements 32 on both sides. The support elements on the ceiling plate 1 which are complementary to the holding elements 32 and omitted in the drawing should, as mentioned, make it possible to release the positive connection with the holding elements 32 if the ceiling plates 1, 1 'and in particular the ceiling plate 1' mutually and around the holding elements 32 are pivoted and the flanges 12d, 12e 'come out of engagement. It is then ensured that each individual ceiling tile 1 can be removed from the support structure without changing anything else. The pivotability of the ceiling panels 1 is improved if the flanges 12d, 12e 'are bounded by notches 12f (FIG. 2) and the height of the edge pieces 12a is as low as possible, as shown in FIGS. 2 to 4.

Fig. 7 shows that the carrier 2 can also be reversed T-shaped, so that their straps 21a serve as a base for the ceiling panels omitted in the drawing and the webs 21b for fastening the carrier 2 on appropriately designed suspensions 4. The suspensions 4 to be fastened to the ceiling of the room end in flat retaining tabs 41 which are pushed between the web strips 21b, s and each with spring pieces 41a located at their end fall into suitable openings 21c provided in the base sheet metal body 21 and on in this way lock the carrier 2 with the suspensions 4. 7, such an opening 21c is arranged as a slot in the web 21b, the spring pieces 41a not projecting beyond the slot and therefore not hindering the movement of the holding pieces 3 along the carrier 2. Fig. 7 also shows that the web strips 21b, s in the area of the suspension 4 are slightly widened by this; this can be limited to such an extent that there is again no fear of obstruction of the holding pieces 3.

8, 8a show an alternative suspension for the carrier, in which, as a modification to FIG. 7, slots 21c in the web 21b can be dispensed with.

The hanger 5 consists of a bent sheet metal strip 51, from which a tongue 52 is bent, which runs parallel to a section 53 of the carrier 2. This tongue 52 engages in the guide groove N1 of the carrier. The second section 54 of the hanger 5 engages in the groove N2 of the carrier 2, the distance between the end 54 and the tongue 52 essentially corresponding to the height of the carrier 2. The hanger 5 is then usually attached to the substructure.

9, 9a show a perspective view of a ceiling which is fastened by means of the support 2 and hanger 5 according to the invention. The upper ends 55 of the length-adjustable hangers are attached to a substructure or a ceiling plate. The right-angled connection of the carrier 2 is advantageously carried out with corner elements 6, which are also inserted into the opposite guide grooves N1 and N2. As an alternative, the ceiling plate 1 can also be placed on the lower flange of the support 2 (FIG. 9).
