Description

The invention relates to a fastening system for retrofitting cover plates on ceilings or Walls.

Building elements, such as walls and ceilings, in particular Reinforced concrete ceilings are no longer in conventional, but created in prefabricated construction.

The decision is made in particular Reinforced concrete ceilings that require thermal insulation, often for the subsequent attachment of insulation boards. So that becomes a Damage to the panels, which also serves as a ceiling soffit serve, excluded.

A fastening system for suspended ceilings is known from US-A-3417535. At In this system, the profile hangers on anchor rails attached below the ceiling attached. This means that insulation boards do not lie directly on the ceiling possible.

The object of the invention is to provide a fastening system through the cover plates, especially insulation boards, in economical way directly on the wall or on the ceiling Attached and fast, inexpensive and safe too can be assembled and replaced by one person.

This task is carried out by a fastening system with the Features of claim 1 solved.

Accordingly, the rails over their support head in one provided on the lower part of each profile hanger Receiving opening inserted, for example inserted until hang them parallel to the ceiling or wall to be covered or stand and at the same time perpendicular to the longitudinal direction of the Anchor channels are slidably arranged. After that, the Cover plates, for example thermal insulation boards, so on lower support head leg (support or support leg) each two successive profile rails in rows hung up that the lower visible side on the The support head legs of the profile rails rest and at the same time with its top, for example on the reinforced concrete ceiling queue up. This has the advantage that e.g. First all profile rails in the anchor channels relatively short profile hangers are preassembled or suspended, after which step the insulation boards on the DIN rail legs of successive profile rails put on and the profile rails pushed gradually will.

In the fastening system, the profile rails each have two support legs (support head legs) for the cover plates on, forming a support profile (support profile). The one Profile hangers with hammer head are above this Hammer head slidably suspended in the anchor channels, while at least partially over their other end longitudinally displaceable on the support rails (profile rails) are attached. The profile hangers are dimensioned so that the clear height between the contact surfaces of the legs the profile rails and the surface of the wall to be covered or Blanket is substantially equal to the thickness of the cover plates. This opens up the possibility of the plates for example on a reinforced concrete ceiling using a flexible Attach the rail system directly without drilling or dowelling have to. The only requirement is that before assembly anchor rails are inserted in the wall or ceiling element.

Profile rails with an H-profile are used in cross-section.

The profile hanger consists of flat material, for example made of sheet steel, and is in one piece. The lower part, i.e. of the the part of the profile hanger opposite the hammer head bent out like a cheek from the slope level and has one Breakthrough for the movable mounting of the support head Profile rail and of course a slit-shaped one Passage for a small part of the middle leg. This gives you the option of starting the assembly process the total number of required profile hangers in the insert appropriate anchor channels, after which the Profile rails over their support head into the receiving openings of the lower hanger part of the profile hanger, i.e. to be "threaded".

In the lower part there is at least one from the bottom up guided, slot-shaped incision made, whereby at least two sheet metal tabs are formed in the transverse direction both the lower part of the profile hanger and the supporting profile are so shaped that they alternate the rail head reach around and hold it movably.

The profile hangers can be designed and manufactured that essentially in the course of the hanger central axis of outside, in the direction of the hammer head, a slot was made that divides the lower hanger part into two arms. These are each in the opposite direction from the Hanger level baking or U-shaped to match the respective support head of the respective profile rail, bent out. This encloses them in the longitudinal direction of the profile rail seen the support head in opposite directions.

A particularly good bracket is achieved when in the lower Hanger part two parallel to each other, in the longitudinal direction of the Suspended slots are introduced. The result formed three relatively narrow, resilient arms embrace the Support head alternately and therefore relatively safe, too with a relatively small hanger or arm width.

For the use of the profile hangers according to the invention in Connection with H-support rails are their arms bulges correspondingly strongly U-shaped, the respective lower, supporting legs essentially horizontally to the Profile middle leg is introduced. Here can by large transverse width of the arms a vertical snap of the Support head can not be realized in this. According to one another embodiment of the hanger can be attached to the lower, horizontal support legs of the arms for longitudinal extension angular, essentially diagonal Passage slot may be provided. The lower legs are at the corners adjacent to the incision cut off or reset, which makes it an insertion or. Form passage slot, which is an easy insertion of the Support head allowed. By relative pivoting and mutual parallel alignment of rail and hanger the legs of the support head are on the lower, now an approximately triangular shape of the arms put on. Despite slotted bevels, these still have one sufficient rigidity to act safely. The Assembly takes place simply by the profile hangers in envisaged number, in the spatial end position, with the T-head inserted into the anchor channels and 90 ° can be hung pivoted. After that, a rail is under the hangers held up one by one and lifted be pivoted horizontally so that the passage slot is aligned parallel to the rail. By lifting the The support head becomes the rail through the hanger slot pushed, after which the hanger is pivoted back until the Support head is parallel to the curved base of the U-arms. Then the rail is lowered with a hanger and hangs over it in the anchor channel.

To prevent the profile hangers from moving further unintentionally swivel and thereby the rails out of them two parallel ones can fall out in the lower part of the hanger Incisions are provided which form three arms. You can two neighboring arms relatively broad and supportive and the third Arm relatively narrow and the support head not up to it Be underside encompassing. The so educated The spring tongue therefore has no support but only one Path limitation function. It closes at her horizontally guided arm part with a hook that essentially consists of there is a 90 ° bend leading downwards. When inserting of the support head in the passage slot between the two wide, supporting arms, the hook end of the spring tongue is in Pushed in the direction of insertion. After swiveling the hanger and parallel alignment of the support head and arms, the snaps Hook the spring tongue over the longitudinal edge of the support head applying this, which prevents pivoting back becomes. When dismantling the spring tongue with its hook end from Lift the support head, after which pivoting is possible.

In the version with only one incision or only two arms and insertion slot provided therein can against unintentional swiveling and falling out of the rails supporting, lower leg of the arms anti-pivoting be trained.

So the lower legs from the U-shape with in essentially parallel legs, further deformed inward be tapering the support opening in the central zone. At the Swiveling the support head must then against the spring force of the lower leg are knitted to this in the support opening to be able to introduce. The support head is thus between the Thighs of the arms held firmly. For easier Swinging in the hanger is cheap here, one Insertion bevel, for example by slightly bending the lower leg to be provided.

The invention is described below using exemplary embodiments explained in more detail with reference to the drawing.

The profile hanger 101 shown in FIG. 1 has one Cross part 99 and one arranged above, via a Neck part 100 connected hammer head 16. Here is the one-piece embodiment of the profile hanger and its Support leg formation particularly well recognizable, the two opposing arms 27, 28 for forming a support opening 30 includes.

Fig. 2 shows a hanging process in steps I. to IV. for a profile hanger 101 and an H support rail 70. The profile hanger 101 becomes parallel in the longitudinal direction of the head to extend an anchor rail 10 vertically upwards into the Anchor rail inserted, according to arrow 43 by 90 ° rotates and on the support legs 9 of the anchor rail 10 discontinued. Thereafter, according to the arrows 44 and 45 H-support rail 70 in the support opening 30 of Profile hanger 101 inserted to, as shown under IV. In optimal shift recording condition for support or Push on the ones placed on the previous profile part Serve insulation boards.

In Fig. 3, a profile hanger 102 is shown, which is under construction basically corresponds to the hanger 101 from Fig.1. Of the Profile hanger 102 has two vertical cuts 26 which but are not evenly spaced. So there is part 67 from a wide arm 27 and a narrow spring tongue 103, while another part 68 consists of only one arm 28, the is the same width with the arm 27. The arms 27, 28 are on the with respect to the intermediate incision 26 opposite corners beveled or angled to Longitudinal alignment of the hanger cut so that parallel Cut edges 104 are provided, one between them Release passage slot 105. The slot 105 has one slightly larger width than the support head 69 of the to be introduced H-profile rail 70. To a sufficient slot width the support leg can get further than up to the bending edge be cut out at an angle, creating a step in the arch part the arms are formed. The spring tongue 103 has on her outer end a hook 106 which consists of a substantially 90 ° arc part, which the support head leg 69 in Supports transverse direction. The spring tongue is relatively narrow designed so that it is vertically elastic.

A cover plate 1 is then between a support leg 69 and a supporting head arch leg 13 of the H profile rail 70 inserted.
