EP0433597A1 - Device to fix façade plates with rear ventilation on a building - Google Patents

Abstract

The device serves to fix facade plates (P) with rear ventilation on a building (B). For this purpose, vertical rails (S) are fixed on the building (B), on which rails are fixed supporting brackets (1) fixed vertically adjustably at selectable distances. Each supporting bracket (1) has at least one, preferably two, upwardly directed supporting extensions (11) and a, preferably interposed, retaining spring (14) acting away from the building. Attached to the building-side rear (PR) of each facade plate (P) is a support (T). The support (T) is preferably T-shaped in cross-section, its downwardly projecting support web (2) engaging between the supporting extensions (11). The retaining spring (14) acts on the support (T), in this case preferably on the support web (T2), in such a way that the support flange (T1) is pressed by its two flange noses (T3, T4) in each case into one building-side horizontal retaining groove (12; 13) of each supporting extension (11). Each facade plate (P) is thereby individually mountable and demountable. Where a higher stability of the plate is desired, it can be provided below the said support (T) additionally with a further support (T) which cooperates with a bearing bracket (2). <IMAGE>

Description

The invention relates to a device according to the preamble of claim 1.

It should be noted that in the invention, for reasons of fire protection alone, the construction elements usually consist at least largely of metal and the facade panels, for example, of ceramic material.

Such a device is known from EP-B1 0 215 993. It has the great advantage over earlier devices, as are known from the AU-B 413 954, AU-B 52 0 993, FR-A 2 094 397 and FR-A 2 528 484, that the plates are individual can be used and removed, i.e. can be replaced individually. This individual interchangeability means great effort and cost savings when building and repairing a facade.

In the construction of this abovementioned EP-B1 0 215 993, each support bracket has a downward-pointing rigid extension on its underside, which is at the top of the Bearing structure on the outside of the facade panel. A spring clamped on the vertical rail presses the assembled facade panel against the rigid extension in such a way that the facade panel can be pressed in against the spring in the direction of the wall. The lower edge of the assembled facade panel is held by a similar support bracket located below with a detachable extension pointing upwards. Here, too, a spring clamped to the rail presses the mounted facade panel against the movable extension so that it can be pushed into the wall. The facade panel holds the movable extension under spring action. The movable extension can therefore only be removed or inserted when the facade panel is pressed in. Once removed, the facade panel can be swung out at the bottom and removed downwards. The insertion can be reversed.

• Die Montage des starren Teils der Trägerkonsolen kann in einem (einheitlichen) Arbeitsgang vor dem Einschieben der Fassadenplatten ausgeführt werden. Das wirkt sich auch hinsichtlich der Einzelauswechselbarkeit der Fassadenplatten positiv aus; in einem (wiederum einheitlichen) Arbeitsgang kann man die Fassadenplatten montieren, wobei sie einzeln eingesetzt werden können. Jede Fassadenplatte sichert dabei durch ihr Gewicht den bei ihrer Montage eingesetzten beweglichen Teil der Trägerkonsole. Wegen dieser Einzelmontage der Fassadenplatten kann man an verschiedenen Orten gleichzeitig mit der Montage der Fassadenplatten beginnen. Man kann Aussparungen für die Baugerüst-Befestigung am Gebäude belassen, die man erst während des Gerüstabbruchs verschliessen kann. Diese Einzelmontierbarkeit wirkt sich auch hinsichtlich der Einzel-Auswechselbarkeit der Fassadenplatten positiv aus. Man braucht zum Montieren der Fassadenplatten kein Werkzeug, sondern kann die Montage von Hand vornehmen.
• Die Fassadenplatten bleiben einzeln auswechselbar, ohne dass man die zu ihrer Befestigung dienenden Teile der Trägerkonsolen deformieren bzw. zerstören müsste.
• Die so befestigten Fassadenplatten können sich allseits spannungsfrei, unabhängig von der Unterkonstruktion, deformieren. Verformungen, sei es durch Eigenspannungen oder Drittkräfte wie Temperaturschwankungen, Windlast, Gebäudeverformungen, können daher nicht mehr zu Beschädigungen führen. Durch die entsprechende Dimensionierung der Federn, welche zwischen den Schienen und den Platten wirken, kann für die Platten zusätzlich jene Festigkeit erreicht werden, die in Anbetracht der zu erwartenden Beanspruchung (Eigenspannungen, Drittbelastungen durch Windlast usw.) gefordert ist.

The construction of the above-mentioned EP-B1 0 215 993 thus has the main advantage of the interchangeability of individual facade panels; in addition, it is much more time-saving than the previous systems:

• The rigid part of the support brackets can be assembled in one (uniform) operation before inserting the facade panels. This also has a positive effect on the interchangeability of the facade panels; The facade panels can be assembled in one (again uniform) work step, whereby they can be used individually. Each façade panel uses its weight to secure the movable part of the support bracket used in its assembly. Because of this individual assembly of the facade panels, you can start assembling the facade panels at different locations at the same time. You can leave recesses for the scaffolding attachment on the building, which can only be closed during the scaffolding demolition. This individual mountability also has a positive effect with regard to the individual interchangeability of the facade panels. You need to mount the Facade panels are not a tool, but can be assembled by hand.
• The facade panels can be replaced individually without having to deform or destroy the parts of the support brackets used to secure them.
• The facade panels fastened in this way can deform without tension, regardless of the substructure. Deformations, whether due to internal stresses or third-party forces such as temperature fluctuations, wind loads, building deformations, can therefore no longer lead to damage. Through the appropriate dimensioning of the springs, which act between the rails and the plates, the strength can additionally be achieved for the plates, which is required in view of the expected stress (internal stresses, third-party loads due to wind load, etc.).

• beim Montieren muss man nämlich die Fassadenplatte solange etwas angehoben und gegen die Federkraft eingedrückt halten, bis die beiden beweglichen Fortsätze in die zugehörigen Trägerkonsolen eingesetzt sind;
• beim Herausnehmen einer Fassadenplatte muss man diese gegen die Federkraft eindrücken und etwas anheben, bevor man an die beiden genannten beweglichen Teile der Trägerkonsole herankommt, und man muss die Fassadenplatte so gehoben und eingedrückt halten während man die genannten beweglichen Teile der Trägerkonsolen entfernt.

One disadvantage of parts of the handling when assembling and disassembling individual facade panels could be regarded as disadvantageous:

• when assembling you have to keep the facade panel slightly raised and pressed in against the spring force until the two movable extensions are inserted into the associated support brackets;
• when removing a facade panel you have to press it in against the spring force and lift it slightly before you can get to the two mentioned moving parts of the carrier console, and you have to keep the facade panel raised and pressed in while removing the above-mentioned moving parts of the carrier console.

The invention has for its object to simplify the assembly and interchangeability of ventilated facade panels and to obtain all of the advantages described above at least equivalent.

To achieve this object, the device characterized in claim 1 is proposed.

To mount a facade panel, you only need to hold it up to the rails at a suitable height so that the end areas of the girder are just above the two associated support brackets. Now you can let go of the facade panel, with the support being held by the support brackets. So the facade panel can no longer crash. In a preferred embodiment, the carrier web passes between the two support extensions of the support brackets on the side of the retaining spring (located between the support extensions) facing away from the building. The carrier flange lies with its flange lugs on the carrying extensions. If you now press the facade panel in the support area against the retaining spring towards the building, the flange lugs mentioned get onto the side of the supporting extensions facing the building, so that the facade panel can sink through its own weight until the support flange rests on the structural extension. Now the flange lugs are in front of the holding grooves. If you let go of the facade panel again, the retaining spring presses the flange lugs into the retaining grooves. The assembly is finished.

The disassembly can be done the other way round: one presses the facade panel in the support area a little to remove the flange lugs from the holding grooves, whereupon the facade panel is lifted a little and can be pushed outwards in the raised state by the retaining spring. Now you can simply remove the facade panel upwards and outwards.

There is no need to laboriously hold when inserting or removing the moving parts.

The on-site flange nose of the carrier flange is preferably hook-shaped at the bottom of the carrier flange and grips the associated extension from above.

The retaining grooves of the support extensions of one of the two support brackets interacting with the same support should preferably have a lower coefficient of friction compared to the flange lugs of the support flange engaging therein than is the case with the support grooves of the support extensions of the second support bracket interacting with the same support flange.

This ensures that no stresses occur and, for example, the same point, which has the lower coefficient of friction, always takes up movement during dilation movements, so that the facade panels do not migrate. If both friction coefficients were the same, the location of the movement would not be determined and facade panels could move.

This can be realized very easily by the fact that the holding grooves with a lower coefficient of friction are made of plastic and the holding grooves with a higher coefficient of friction are made of metal.

Because the rails, the support brackets and the supports, as well as their fastening elements are preferably made of metal, there is no need to fear that the plastic will be damaged in the event of a fire; because the metal support web sits between the metal support extensions of the support bracket so that the facade panel cannot fall off.

Basically, you could, especially in the preferred embodiment, attach each facade panel with only a single support, which can be done advantageously with relatively small vertical dimensions of the facade panels.

• an der Rückseite jeder Fassadenplatte sind zwei Träger angebracht, von denen der obere in geschilderter Weise mit den beiden Tragkonsolen zusammenwirkt, während der untere der beiden Träger mit seinem Trägersteg in zwei an verschiedenen Schienen unterhalb der Tragkonsolen höhenverstellbar befestigte Stützkonsolen eingreift, und
• jede Stützkonsole hat, zwei nach oben gerichtete Stützfortsätze und eine dazwischen sitzende Stützfeder,
• welche Stützfeder derart an der dem Bauwerk zugewandte Innenseite des Trägerstegs anliegt, dass der Trägersteg an die dem Bauwerk zugewandte Innenseite jenes Stützfortsatzes gedrückt wird, welcher vom Bauwerk entfernter gelegen ist; Die Fassadenplatte kann zusammen mit dem Träger entgegen der genannten Stützfeder zum Bauwerk hin eingedrückt werden.

The following preferred embodiment is recommended for a particularly solid construction:

• on the back of each facade panel, two supports are attached, of which the upper one cooperates with the two support brackets in the manner described, while the lower of the two supports engages with its support web in two support brackets which are fastened to different rails below the support brackets, and
• each support bracket has two support extensions pointing upwards and a support spring in between,
• which support spring bears against the inside of the carrier web facing the building in such a way that the carrier web is pressed against the inside of the supporting extension facing the building, which is located further away from the building; The facade panel can be pressed together with the carrier against the mentioned support spring towards the building.

In this construction, an embodiment of the invention is particularly preferred in which the coefficient of friction of the support grooves, which have the higher coefficient of friction, is higher than the coefficient of friction between the carrier web and the point of cooperation of the support extensions which are further away from the structure.

Then the location of the greatest friction is located at the carrier grooves with the higher coefficient of friction, so that e.g. when the facade panels are dilated, all other three fastening points slide more easily than the first. This prevents any walking of the facade panels.

The difference in the coefficient of friction is preferably achieved by the fact that the support extension cooperating with the support web has a plastic insert at the point in contact with the support web.

Here, too, there is no risk of falling in the case of an otherwise metal construction because the metal support web sits between the metal support extensions.

In all cases, it is preferred if each retaining spring and each support spring abuts the carrier web with a cambered side. This can prevent undesired tilting during assembly work and during dilatation movements. This is without prejudice to the influencing of the dilatation movements by different friction coefficients discussed above.

A smooth outer surface of the facade, free of fastening elements, may not only be desirable from an aesthetic point of view; also technical advantages (for example, ease of cleaning can make the absence of externally visible fastening parts desirable. To this end, it is preferred if each support is connected to the facade plate at two fastening points which are concealed on the rear side of the associated facade panel.

It may also be necessary to exclude tensions between the support and the facade panel connected to it, which can be caused, for example, by dilation. For this purpose, a construction is preferred which is characterized in that each support is fixedly attached to one of the two fastening points and horizontally displaceable on the other relative to the facade panel. The fixed attachment is preferably effected by a suitable form fit or by a clamping screw. You can promote the sliding at the displaceable point by a so-called lubricating intermediate layer between the otherwise metallic parts.

According to the invention, an easy to assemble and disassemble construction has thus been created which retains the aforementioned advantages and in some cases brings new advantages as described above.

Such a facade can be installed as follows:

After the substructure (here, the vertical rails S) has been attached to the structure B (by means of spacers, not shown), the support brackets 1 and the support brackets 2 are mounted on the rails S at the predetermined intervals.

The support brackets 1 are combined with the mounting bracket 16; through the mounting bracket 16, the screw S3 is inserted, which is inserted and clamped with the hammer nut S2 into the associated support groove S1 of the rail S.

The support brackets are attached similarly, only that the Screw S3 (without mounting bracket) is passed directly through the mounting opening 26 of the support bracket before it is provided with the hammer head nut S2 and the latter is placed in the support groove S1 of the rail S.

All of the above parts are made of metal.

Each support bracket 1 has two upwardly directed support extensions 11, which are essentially parallel to the structure B, and a retaining spring 14 arranged between them. Each upper support T of a facade panel P is assigned two support brackets 1. One of these support brackets 1 is completely metal, so that the horizontal support grooves 12 of the support extensions 11, which are open towards the building B, are also metal. The other support bracket 1 has 11 plastic support grooves 13 with a lower coefficient of friction on their metal support extensions. The effect of these design features has already been described. 10 shows the two different support brackets, while otherwise only the metal version is shown for the sake of simplicity. The retaining spring 14 faces the support web T2 with a cambered side 15, which is favorable in terms of assembly and friction.

Analogously, the support brackets 2, which are completely metallic with the exception of the plastic insert 23, are shown with support extensions 21 and support spring 24 and only in FIG. 11 is the plastic insert 23 in the insert groove 22 designated, whereby a coefficient of friction as low as that of the plastic retaining grooves 13 is achieved. The effect in itself is the same as that already described for the holding grooves 12 and 13. The holding groove 12 with the higher coefficient of friction thus serves as a kind of fixed point, while easier sliding is possible on the plastic parts 13 and 23. The support spring 24 also turns the support web T2 a cambered side 25 to create more favorable conditions for cooperation.

Each facade panel P has a rear side PR facing the building B, at which fastening points PF are provided, in each of which a screw and nut holds a holder P1. Each of two cooperating brackets P1 has a clamping screw P2 for fixing the carrier flange T1 of the carrier T inserted in the bracket P1, while it can slide in the other bracket P1 to compensate for stresses, as has already been described.

Each carrier T is T-shaped. It has the support flange T1 just mentioned, from which the support web T2, which has also already been mentioned, projects downward. The carrier flange T1 has two lugs T3 and T4, of which the inner flange lug T4 runs downward and outward in the manner of a hook in order to encompass the associated holding extension 11.

The assembled state is shown in FIGS. 1 to 4, 10 and 11.

The assembly can be seen well in FIGS. 5 to 9. The facade panels P are approached to the rails 1 in such a way that the supports T are located above the brackets 1 and 2, respectively. If there is already a facade panel at the top, the newly added facade panel P will be moved slightly obliquely, as shown in FIG. 5.

The facade panel P is now lowered into the state shown in FIG. 6, for which purpose it could simply be released, which is just not done to avoid knocks. Now the carrier webs T2 are already between the outer support extension 11 and the retaining spring 14 or between the outer support extension 21 and the support spring 24. The facade panel P is thus already secured against falling. The carrier flange T1 lies with its flange lugs (not shown in FIG. 6) on the carrying extensions 11.

The facade panel P is now pressed against the retaining spring 14 and reaches the intermediate position shown in FIG. 7.

From this position according to FIG. 7, the facade panel P already sinks under the effect of its weight (you have to help a little at most) down to the position shown in FIG. 8, in which the support flange T1 rests on the structural extension 11.

If you now let go of the facade panel P, it is pushed forward by the retaining spring 14, the flange lugs T3 and T4 engaging in the retaining grooves 12 (or possibly 13).

Disassembly can be done in reverse.

All parts are made of metal, preferably light metal, with the exception of the springs and with the exception of the parts made of plastic, which can be seen in particular from FIGS. 10 and 11.

Here too, the simple, safe and single-plate installation can be seen.
