EP3033458B1 - System for thermal activation and fastening of ceiling panels - Google Patents

Description

The invention relates to a system for thermal activation and fastening of a ceiling panel.

Such a system is for example in DE 20 2007 010 215 U1 explained. Ceiling panels and their thermal activation, ie so-called radiant ceiling panels, are known per se. Ceiling panels are suspended from suspension structures or assembly structures, for example on concrete or wooden ceilings, or are fixedly mounted. The so-called activation of ceiling panels, ie the attachment of a module for heating or cooling the ceiling panel, can take place, for example, by means of a pipe register in which a heat transfer fluid is transported that is in thermal contact with the ceiling panel. Alternatively, the thermal activation can take place electrically resistively. Radiant ceiling panels can be used for both heating and cooling a room, depending on the temperature of the heat transfer fluid based on the spatial average equilibrium temperature of the room below the radiant ceiling panels.

In practice, many of these systems prove to be too expensive for some potential buyers in terms of material costs and installation costs. This applies in particular to the installation of small areas of thermally activated radiant ceiling panels for private customers.

The invention is based on the object of simplifying the thermal activation and fastening of ceiling panels and thus reducing installation costs.

To solve the problem, a system according to the technical teaching of claim 1 is provided.

A hook-like means is either formed by folding the plate with a hole in the edge in which a hook is inserted or is formed by at least one flap that is folded out on the plate and has a hole in which a hook is inserted.

This enables, for example, the following installation procedure.

Step 1:

The two support rails assigned to the ceiling plate are above the Mounting position of the ceiling plate fastened directly or indirectly to the ceiling by means of the mounting rail fastening means.

Step 2:

Suspending the activation module by providing the two hook-like means spaced apart from one another on a first edge region of the activation module, whereby the activation module is suspended pivotably on one of the two support rails and its sheet metal hangs down essentially vertically.

Step 3:

Pushing up the ceiling panel and thereby pivoting the activation module up, after which the ceiling panel is fastened to the support rails by means of the ceiling panel fastening means. The activation module or its sheet metal, which is only suspended on one side, then rests in a horizontal position on the ceiling plate attached to the support rails, which creates good thermal contact.

To ensure that the entire lower large area of the activation module rests on the entire upper large area of the ceiling panel, the vertical length of the hook-like means, if they are provided on the activation module, is greater than the vertical distance between the hooking point on the support rail and the lower end the mounting rail. If the hooking point of the hook-like means is at the upper end of the support rail, the vertical length of the hook-like means, if they are provided on the activation module, is greater than the height of the support rail.

According to an improved embodiment of the invention, the system also has a third hook-like means which can be provided on a second edge area of the activation module opposite the first edge area of the activation module.

This enables, for example, the following more convenient installation procedure.

Step 1 remains unchanged.

Step 2:

Suspending the activation module by providing them at a distance from one another the two hook-like means on a first edge area of the activation module and the third hook-like means on a second edge area of the activation module opposite from the first edge area of the activation module, whereby the activation module is suspended on both mounting rails and the sheet metal of the activation module is slightly lower than in an essentially horizontal position the lower ends of the mounting rails is suspended.

Step 3:

Pushing up the ceiling panel and slightly lifting the activation module, after which the ceiling panel is fastened to the support rails by means of the ceiling panel fastening means. The activation module or its sheet metal, which is only suspended on both sides, then rests in a horizontal position on the ceiling plate attached to the support rails, which creates good thermal contact.

According to an even further improved and particularly preferred embodiment of the invention, the system has two further hook-like means, which can be provided at a second edge area of the activation module opposite from the first edge area of the activation module and by means of which the activation module can be suspended pivotably on the other of the two mounting rails .

This enables, for example, the following, even more pleasant installation procedure.

Step 1 remains unchanged.

Step 2:

Suspending the activation module by providing the two hook-like means spaced apart from one another on a first edge area of the activation module and the two further hook-like means on a second edge area of the activation module opposite from the first edge area of the activation module, whereby the activation module is suspended on both support rails and the sheet metal of the activation module in a substantially horizontal position is suspended slightly lower than the lower ends of the support rails.

Step 3:

Pushing up the ceiling panel and slightly lifting the activation module, after which the ceiling panel is fastened to the support rails by means of the ceiling panel fastening means. The activation module or its sheet metal, which is only suspended on both sides, then rests in a horizontal position on the ceiling plate attached to the support rails, which creates good thermal contact.

It can be seen that the system according to the invention enables a combination of activation and fastening of a ceiling panel in a simple, easily carried out method.

According to the invention, a hook-like means is either by means of at least one folded out on the sheet metal

Formed tab which has a hole in which a hook is inserted.

According to the invention, a hook-like means can also be formed by folding the sheet metal with a hole in the edge into which a hook is inserted.

The hook used is preferably a spring hook. A particularly preferred spring hook is an approximately U-shaped structure. The length of the U-legs depends on the hook length requirement described above. The end sections of each U-leg are angled, an angle of approximately 90 ° being preferred. The end section of the U-shaped structure having the connecting section between the two U-legs is bent over to form a hook. This spring hook can by elastically compressing the two U-legs, for example through the above-mentioned hole in the edge of the fold of the sheet metal to be introduced. When the elastic compression is ended, the two U-legs move back to the position which corresponds to their tension-free or tension-free state. The spring hook is thus attached to the sheet metal of the activation module or “provided” thereon in accordance with what has been said above.

A hook-like means can also be formed by a hook that can be folded out of the sheet metal. In this variant, the hook contour is punched out in the sheet metal. A perforation line is preferably punched out where the hook is to be folded out in order to make it easier to fold it out by bending at this perforation line.

The system preferably has at least one pressing means assigned to the ceiling panel for pressing the activation module against the ceiling panel. As a result, the areal contact between the lower large area of the activation module (sheet metal of the activation module) and the upper large area of the ceiling plate can be improved if necessary in order to optimize the thermal contact.

This pressing means can be formed by a leaf spring with a first hook end and a second hook end, between which five leaf spring sections extend in succession, of which a first essentially straight section extends from the first hook end to a first strongly curved one in the tension-free state of the leaf spring Section extends, a slightly curved section extends from the first strongly curved section to a second strongly curved section, and a second substantially rectilinear section extends from the second strongly curved section to the second hook end. The leaf spring can be latched with the first hook end on the first of the two support rails and the second hook end on the second of the two support rails in such a way that the bulge of the curved section of the leaf spring points towards the floor.

The pressing means must be attached to the mounting rails between steps 1 and 2 described above.

The support rails can be C-profile rails or U-profile rails with bevels at the ends of the C or U, in which the hook-like means and / or the hook ends of the leaf spring can engage.

According to a further preferred embodiment of the system, the heat-conducting sheet metal of the thermal activation module is thermally coupled to pipes for a heat transfer fluid.

The sheet metal of the activation module preferably has a centering means at two opposite ends, in particular a bevel with a bore, a V-groove or a side groove, in each of which a collecting tube of the tubes thermally coupled to the sheet metal can be inserted. This ensures that the two end manifolds of an activation module are always in a correctly defined position relative to the sheet metal. This facilitates the assembly and hydraulic interconnection of several activation modules in series.

The tubes thermally coupled to the sheet metal are preferably brought into fluid connection with a manifold tube by means of a distributor piece. The distributor piece can have openings into which the tubes can be inserted into the distributor piece in a sealing manner. The seal between a pipe and the distributor piece can be effected by means of an O-ring, preferably by means of two O-rings spaced along the pipe.

The distributor piece can preferably be fastened to a fold, preferably to two folds, of the sheet metal, in particular by means of snap-in knobs, a screw or a fixing clip. This ensures that the two end manifolds of an activation module are always in a correctly defined position relative to the sheet metal. This facilitates the assembly and hydraulic interconnection of several activation modules in series.

The distributor piece is preferably made of a polymer material. This prevents any corrosion from local electrical voltages and local chemical elements.

In a particularly preferred embodiment, the ceiling panel is a plasterboard ceiling panel, the sheet metal of the activation module preferably being perforated. The perforation reduces the reflection of sound on the sheet metal and thus contributes to the soundproofing of the room.

The sheet metal can be a steel sheet or an aluminum sheet.

The support rails are preferably made of steel and the sheet metal of aluminum.

In Fig. 1 a perspective view of a first embodiment of the system 10 according to the invention in the assembled state and in its assembly environment is shown. The system 10 for thermally activating and suspending a ceiling plate 11 contains a flat thermal activation module 12 which is assigned to the ceiling plate 11 and which has an essentially flat sheet metal 13. The sheet 13 is in thermal contact with two tubes 41, 42. The two tubes 41, 42 branch off from a collecting tube 49. The system also contains two support rails 14, 15 assigned to the ceiling panel 11, which can be fastened directly or indirectly to the ceiling above the mounting position of the ceiling panel 11 and to which the ceiling panel 11 can be fastened. The system also contains mounting rail fastening means 16, 17, 18, 19, 20, 21 for fastening the mounting rails 14, 15 to the ceiling as well as ceiling panel fastening means 22, 23 (see Fig _. 14th ) for fastening the ceiling plate 11 to the support rails 14, 15.

According to the invention, the system 10 contains two hook-like means 24, 25, which can be provided at a first edge region 12L of the activation module 12 at a distance from one another and by means of which the activation module 12 can be suspended pivotably on one of the two support rails 14, 15.

The plate 13 has a perforation 13P to save weight.

The sheet metal 13 also has an upwardly directed first fold 34 in a first edge region 12L and an upwardly directed second fold 35 in a second edge region 12R. The folds 34, 35 serve, on the one hand, to stiffen the sheet metal 13 and, on the other hand, to provide openings in which the two hook-like means 24, 25 can be hung on the sheet metal 13.

In Fig. 2 a perspective view of a first variant of the hook-like means is shown in the state provided on the activation module 12. In this variant 1, a hook-like means 24, 25, 26, 27 is formed in each case by a first flap 29 unfolded from the plate 13, a second flap 30 unfolded from the plate 13 and a spring hook 33 which is attached to a hole 31 in the first bracket 29 and is suspended in a hole 32 in the second bracket 30 on the sheet metal 13. The spring hook 33 is suspended from one of the support rails 14, 15 formed by C-profiles that are open at the top. Preferably, several pairs of flaps 29, 30 that can be folded out and are spaced apart from one another in the longitudinal direction are provided on both longitudinal sides of the sheet metal 13.

• ein erstes Ende 33a des Federhakens;
• ein zweites Ende 33b des Federhakens;
• einen ersten Schenkel 33c des Federhakens;
• einen zweiten Schenkel 33d des Federhakens; und
• einen Aufhängungsbereich 33e des Federhakens.

The spring hook 33 is formed from a wire-shaped elastic material, for example from metal, in particular from steel, or from a polymer such as PET, and has the following sections:

• a first end 33a of the spring hook;
• a second end 33b of the spring hook;
• a first leg 33c of the spring hook;
• a second leg 33d of the spring hook; and
• a suspension portion 33e of the spring hook.

The first end 33a and the second end 33b of the spring hook 33 are bent end portions of a predetermined length of the wire-shaped elastic material.

The first leg 33c and the second leg 33d of the spring hook 33 extend vertically upwards when installed in the system 10 as intended and together form the transition area of the spring hook 33 between its ends 33a, 33b and the suspension area 33e.

The suspension area 33e of the spring hook 33 is located along the length of the wire-like material bent to the spring hook 33 in its central area of the length and is the 180 ° bending area of a U-shaped wire section between the two legs 33c, 33d, which emerges from the plane of the U-shaped wire section is bent out.

To hang the first end 33a of the spring hook 33 in the hole 31 in the first bracket 29 and the second end 33b of the spring hook 33 in the hole 32 in the second bracket 30, the spring hook 33 is pressed against its two legs 33c, 33d with your fingers the spring force of the wire-shaped elastic material is compressed, inserted with the two ends 33a, 33b into the respective holes 31, 32 and finally released by moving the fingers away. As a result, the spring force of the elastically deformed wire-shaped elastic material presses the two ends 33a, 33b into the holes 31, 32 so that the spring hook 33 no longer falls out of the holes 31, 32 and, when installed in the system 10 as intended, by a horizontal one Axis relative to the plate 13 of the activation module 12 is pivotable.

In Fig. 3 a perspective view of a second variant of the hook-like means is shown in the state provided on the activation module 12. The spring hooks 33 used here have the same structure and the same function as the spring hooks 33 used in the first variant.

The sheet 13 of the activation module 12 and a fold 35 of the sheet 13 can be seen, the edge 37 of the fold 35 extending in the longitudinal direction of the

Activation module 12 extends. In the edge 37 there is a hole 36, the dimension of which in the longitudinal direction corresponds to the distance between the two adjacent holes 31, 32 of the pair of tabs 29, 30 of the first variants (see FIG Fig. 2 ) is equivalent to. A plurality of holes 36 spaced apart from one another in the longitudinal direction are preferably provided in the respective edge on both longitudinal sides of the sheet metal 13.

To hang the first end 33a of the spring hook 33 and the second end 33b of the spring hook 33 in the hole 36 in the edge 37, the spring hook 33 is also here pressed together on its two legs 33c, 33d with the fingers against the spring force of the wire-shaped elastic material, with the two ends 33a, 33b inserted into the hole 36 and finally released by moving the fingers away. As a result, the spring force of the elastically deformed wire-shaped elastic material presses the two ends 33a, 33b against the opposite edge areas of the hole 36, which are spaced apart in the longitudinal direction, so that the spring hook 33 no longer falls out of the hole 36 and in it when installed as intended is pivotable in the system 10 about a horizontal axis relative to the plate 13 of the activation module 12.

All spring hooks 33 of the system 10 are dimensioned such that the underside of the activation module 12 suspended by the spring hook 33 is arranged lower than the underside of the upwardly open C-profiles which form the support rails 14, 15 on both sides of the suspended activation module 12. The overhang HH formed in this way between the mounting rails 14, 15 and the activation module 12 is important because it is essential for the mounting of the ceiling panels (not shown) on the undersides of the mounting rails 14, 15 (only mounting rail 15 shown) and the simultaneous thermal activation of the ceiling panels relieved.

When a ceiling panel is brought up to the support rails 14, 15 from below, the top of the ceiling panel comes into contact with the underside of the suspended activation module. When the ceiling plate is raised further, the activation module 12 lies with its underside on the upper side of the raised ceiling plate due to its gravitational force. While the ceiling plate is raised over a further height, which corresponds to the overhang HH, until it finally contacts the underside of the support rails 14, 15 with its upper side, the activation module 12 is always flat with its underside on the upper side the ceiling plate. Even after the ceiling panel has been mounted on the support rails 14, 15, the activation module 12 rests on the ceiling panel over a permanent large area, which means that there is good thermal contact between the activation module 12 and the respective ceiling panel.

In Fig. 4 a perspective view of a third variant of the hook-like means is shown in the state provided on the activation module 12. The sheet metal 13 of the activation module 12 and a hook 13H formed from a part of the sheet metal material and folded out of the sheet metal 13 can be seen. A plurality of hooks 13H which can be folded out and which are spaced apart in the longitudinal direction are preferably provided on both longitudinal sides of the sheet metal 13 by partially punching out.

In Figures 5A, 5B, 5C a perspective view of a first, second and third variant of the centering means 12C is shown.

In Figure 5A the centering means 12C is formed by a central, end-face bevel 44 of the activation module 12, which has a round hole or a bore 45 in which the collecting tube 49 is mounted and centered. In addition, three tubes 41, 42, 43 can be seen, which branch off from the collecting tube 49 and are in thermal contact with the activation module 12.

In Figure 5B the centering means 12C is formed by a central, end-face bevel 44 of the activation module 12, which has a side groove 47 in which the collecting tube 49 is supported and centered.

In Figure 5C the centering means 12C is formed by a central, end-face bevel 44 of the activation module 12, which has a V-groove 46 in which the collecting tube 49 is supported and centered.

In Fig. 6 a perspective view of a further variant of the sheet metal 13 is shown. Here, too, the centering means 12C is formed by a central, end-face bevel 44 of the activation module 12. The sheet 13 shown here differs from the sheets of Figures 5A, 5B, 5C in that it has, on the one hand, two rows of perforations 13P with round holes and, on the other hand, has a semicircular groove 48 in which the collecting tube 49 is supported and centered.

In Fig. 7 a perspective view of manifold 50 is shown. The distributor piece 50 serves to distribute the heat transfer fluid from the collecting tube 49 to three tubes 41, 42, 43. The distributor piece 50 is fastened to the sheet metal 13 and has a first opening 51 for the sealed reception of one end of the tube 41, a second opening 52 for sealed reception of one end of the tube 42, a third opening 53 for the sealed reception of one end of the tube 43 and a fourth opening 59 for the sealed reception of one end of the manifold 49 of the manifold 50 in fluid communication.

In Fig. 8 FIG. 3 is a sectional view of manifold 50 of FIG Fig. 7 shown. The end of the tube 41 inserted into the opening / bore 51 as well as the in the end of the tube 42 inserted into the end of the opening / bore 52. The tubes 41 and 42 are shown in phantom in longitudinal section. The collector tube 49 inserted into the opening / bore 59 can also be seen. The collector tube 49 is shown in cross-section with dashed lines. All pipe ends of the pipes 41, 42, 43, 49 are sealed or inserted fluid-tight in the corresponding openings / bores 51, 52, 53, 59 of the distributor piece 50 by two O-rings OR1 and OR2 arranged in series. In Fig. 8 one can see the two O-rings OR1 and OR2 between the tube 41 and the opening / bore 51 and between the tube 42 and the opening / bore 52 of the distributor piece 50.

In Fig. 9 FIG. 8 is a perspective view of the manifold of FIG Fig. 7 shown in the assembled state on a sheet metal 13. The distributor piece 50 can be seen, which is attached to two folds 54, 55 of the sheet metal 13.

In Figures 10A, 10B, 10C A side view of a first, second and third variant of the fixing of a distributor piece 50 to the sheet metal 13 is shown. The viewing direction is in each case transverse to the longitudinal direction of the sheet metal 13. A fold 55 of the sheet metal 13 can be seen.

In Fig _. 10A the distributor piece 50 is fastened to the fold 55 by means of a snap-in nub 56.

In Figure 10B the distributor piece 50 is fastened to the fold 55 by means of a screw 57.

In Figure 10C the distributor piece 50 is fastened to the fold 55 by means of a fixing clip 58.

In Fig. 11 a perspective view of a manifold 50 with a fixing clip 58 for a manifold 49 is shown.

In Fig. 12 A perspective view of a manifold 50 having a manifold 49 with a quick coupling 60 is shown.

In Fig _. 13th a perspective view of a pressing means 38 is shown. The pressing means 38 is formed by a leaf spring 38 with a first hook end 38a and a second hook end 38g, between which five leaf spring sections 38b, 38c, 38d, 38e, 38f extend in succession, of which the tension-free State of the leaf spring 38, a first substantially straight section 38b extends from the first hook end 38a to a first strongly curved section 38c, a slightly curved section 38d extends from the first strongly curved section 38c to a second strongly curved section 38e, and a second substantially straight section 38f extends from the second strongly curved section to the second hook end 38g. The pressing means 38 can be made of metal, in particular steel, or of a polymer material such as PET.

In Fig. 14 Fig. 3 is a sectional view of one of the Fig. 1 corresponding system 10 in the assembled state with the pressing means 38 from Fig. 13 shown. The pressing means 38 shaped in this way is latched with the first hook end 38a on the first of the two support rails 14 and with the second hook end 38g on the second of the two support rails 15 in such a way that the bulge 38D of the bent section 38d of the leaf spring 38 points towards the floor and the activation module 12 presses against the ceiling plate 11. This ensures good thermal contact between the activation module 12 and the ceiling plate 11. Ceiling panel fastening means 22, 23 are used to fasten the ceiling panel 11 to the support rails 14, 15.
