Abstract

A description is given of a method and a fastening system for the subsequent fitting in particular of covering panels on the basic elements of buildings, such as ceilings or walls, in which T-load-bearing profile rails or H-load-bearing profile rails (24, 70) are introduced, via their load-bearing head, into a receiving opening provided on the lower part of a profile suspending means (66). Thereafter, the covering panels (1) are placed in rows on the lower load-bearing or supporting legs (13) in each case of two sequential load-bearing rails (70) such that said panels bear, with their lower visible side, on the load-bearing legs (13) of the load-bearing profiles (70) and, at the same time, are located against the reinforced-concrete ceiling with their upper side. In this arrangement, it is particularly advantageous that the load-bearing rails are pre-mounted or pre-suspended and that, even during the laying process of the panels, they can be easily displaced in the anchor rails by means of the profile suspending means. <IMAGE>

Description

The invention relates to a method and a fastening system for retrofitting, in particular, cover plates to basic building elements, such as ceilings or walls, according to the preambles of claims 1 and 3.

Building elements, such as walls and ceilings, in particular reinforced concrete ceilings, are no longer created in conventional, but in prefabricated construction. This factory production is based on the more cost-effective production and a reduction in construction times.

Multi-layer lightweight building boards as insulation boards are either concreted onto the reinforced concrete ceilings or subsequently attached to them. Precast concrete is only accepted with great restrictions by precast manufacturers. The reason for this is that elementary ceilings are semi-finished parts in which small damage to the ceiling panels - which cannot be excluded during loading, transport and laying - cannot be claimed as a complaint.

That is why construction companies, architects or general contractors, especially in the case of reinforced concrete ceilings that require thermal insulation, decide to retrofit insulation boards. This prevents damage to the panels, which also serve as the underside of the ceiling.

For example, the ROCKWOOL system (brochure C 7.2) is known, in which the insulation boards are attached directly to the concrete ceiling using retaining claws and hammer-in dowels. It is therefore necessary to drill holes for the fastening dowels in the concrete ceilings, which is very time-consuming and costly. Subsequent partial disassembly, for example to replace a damaged plate, is not readily possible.

Furthermore it is known, see also the brochure "G + H ISOVER, No. 50.8.84 K, thermal insulation and sound absorption with ISOVER industrial ceiling tiles IDP / V" from Grünzweig + Hartmann, Glasfaser AG, the panels are suspended over relatively long hangers (slotted band irons) to insert. To insert the insulation boards must be lifted in a significant inclination through the grid openings over the support profile grid and then lowered, so that a relatively large suspension height is necessary. As a result, a lot of space is required, so that this system cannot be used, for example, in underground garages or rooms with a low height because of a great loss of height.

The insulation boards can also be subsequently attached directly to the reinforced concrete ceilings using at least six dowels. Depending on the panel thickness, dowel lengths of 110 to 170 mm must be selected so that the required minimum tie-in depth of 50 mm is achieved. This means that 6 x 60 mm = 360 mm drilling depth is required to install 1 m of insulation board. An additional complication is drilling overhead. Further expenses can be seen in connection with a large drill wear. After a service life of approx. 2000 mm drilling distance (attach approx. 5.5 m slabs) in concrete, for example, an O 8 mm drill is worn out.

Furthermore, a fastening system from Profil-Vertrieb GmbH (brochure "Substructure K 1100, Issue 21.04.90) is known, in which T-profiles bent from sheet metal are put together to form a mounting grid for ceiling panels. The panels lie on the lower legs of the T-profile while the upward-pointing middle leg of the profile has a head shape similar to an I.-profile. The supporting profile grid is attached to the ceiling via profile hangers. These hangers have an L-shaped development for dowelling to the ceiling, while the other end has a breakthrough for slidably gripping the head of the support profiles, but these profile hangers have a considerable height, since there must be a corresponding clear width for the intermediate insertion and lowering of the plates and they must be pre-anchored.

Finally, from the catalog B 90 "Halfen rails for concreting and accessories" from Halfeneisen GmbH & Co. a fastening system for domestic installations, facing ceilings, facade elements etc. is known, in which anchor rails are provided in the corresponding wall or ceiling, which are preferably in the concrete surface are flush and open to the outside. Hammer or T-head screws engage in these anchor channels, which are fixed to the anchor channel with a lock nut and to which various suspension and fastening devices can be attached. For hanging, for example, from acoustic or facing ceilings, over which installation etc. on the anchor channels, possibly also suspended, are guided under the ceiling, anchor screws with a relatively large length are used, at the lower end of which are essentially omega-shaped, downward-opening beams Cross profiles are fastened, for example, by nuts and lock nuts. On the lower, diverging legs of the support rails are the cover elements clipped on from below. The grid is precisely fixed here with countered anchor bolts before the panels are applied (rigid grid system).

The object of the invention is a method and a fastening system o. G. Specify genus through which cover plates, in particular insulation boards, can be attached directly to the wall or the ceiling in an economical manner and can also be installed, replaced and replaced quickly, inexpensively and safely by one person.

This object is achieved by a method having the features of patent claim 1.

Accordingly, the support profile rails are inserted via their support head into, for example, inserted into the lower part of each profile hanger or into an intended receiving opening / support opening until they hang or stand parallel to the ceiling or wall to be covered and at the same time are displaceable perpendicular to the longitudinal direction of the anchor channels are arranged. Then the cover plates, for example thermal insulation boards, are placed in rows on the lower support or support legs of two successive support rails in such a way that they rest with the lower visible side on the support legs of the support rails and, at the same time, rest or rest with their upper side on, for example, the reinforced concrete ceiling. This has the great advantage that z. B. First, all support rails in the anchor rails are preassembled or suspended via relatively short profile hangers, after which the insulation boards are placed on the support arm legs of successive support rails step by step or in a zipper-laying and push-on manner and the support rails are pushed in step accordingly.

This has an advantageous effect if step by step, d. H. Always install a mounting aid after inserting and inserting a panel and pushing the subsequent rail in place to secure the inserted insulation panel against falling out when inserting the next panel.

The object is further achieved by a fastening system with the features of claim 3. Further refinements are contained in subclaims 4 ff.

Accordingly, the support profile rails each have at least one support leg for the cover plates, forming a support profile (support profile). The profile hangers having a hammer head are slidably suspended in the anchor rails via this hammer head, while they are at least partially longitudinally attached to the support rails via their other end. The profile hangers are dimensioned so that the clear height between the contact surfaces of the legs of the support profile rails and the surface of the wall or ceiling to be covered is substantially equal to the thickness of the cover plates. This opens up the possibility of directly attaching the panels to a reinforced concrete ceiling using a flexible rail system, without having to drill or dowel. The only requirement is that anchor rails are already inserted in the wall or ceiling element before assembly. Due to the movability of the profile hangers in the anchor channels, all support profile rails can already be assembled using the hangers. Thus, after positioning a first rail correctly, the plates can be successively z. B. lifted up into contact with the ceiling and pushed or placed on the support surface on the first rail and a second rail can be pushed, etc., so that a successive zipper-like attachment of the plates in direct contact with or on the ceiling is possible .

The fastening system according to the invention has a particularly advantageous effect if relatively thick thermal insulation panels are used as cover panels. These can easily be placed with their underside / visible side on the prepared mounting profile rails, so that they are at the same time with their upper side against the surface to be covered without any loss of space. The thermal insulation boards can therefore be installed with minimum space requirements for prefabricated reinforced concrete ceilings in rooms of low height, such as underground garages.

In a further development of the idea of the invention, any profile rail can be used as the support profile rail, which has an upper head part, on which it can preferably be held in a displaceable manner and has two symmetrically arranged support legs on which the cover plates can be placed or placed securely. T and H profile rails have proven to be particularly advantageous, the T profile rails having a thickening or compression on the middle leg opposite the support legs, similar to the case with T profiles on both sides or ends, a rail or. Forming support head. If H-profile rails are used, the second pair of parallel legs serves as the support head. Thus, the H-rail is held on the pair of support head legs, while the further pair of legs form the support legs for two adjacent cover plates.

It is particularly advantageous, in particular when attaching the plates, if the support rails are dimensioned so that they have a transverse elasticity. In the case of plates inserted between two supporting profile rails, with the spacing of the supporting profile rails at the same height as the inserted plate, the part of the rail not yet equipped with plates can be used to insert further plates larger insertion distance to the previous rail can be kept.

In a further development of the inventive idea, the profile hanger, which has a hammer head or T-head design at one end for slidably engaging in the anchor channels, can be arranged at its other end offset by 90 ° to the axial direction or longitudinal extension of the anchor channels have the support head of a support rail. As a result, the support rail is held on the profile hanger so that it extends substantially perpendicular to the longitudinal extension of the anchor rails. As a result, the support profile rails can be easily moved over the profile hangers along the entire longitudinal extent of the anchor channels. This is of great importance when inserting or removing the cover plates, as will be described in detail below.

The profile hanger can be made of flat material, i.e. H. for example made of sheet steel, formed in one piece, the T-head lying in its longitudinal extent.

The lower part, ie the part of the profile hanger located opposite the T-head, can be bent by 90 ° from the head plane, pivoted about the central axis and a breakthrough for the slidable mounting of the mounting rail head and of course a slot-shaped passage for a small one Have part of the middle leg. This makes it possible to insert the entire number of required profile hangers into the corresponding anchor channels at the start of installation, after which the support profile rails via their support head into the Receiving openings of the lower hanger part of the profile hanger are pushed in, ie "threaded".

The profile hanger made of flat material / sheet metal can also be shaped such that the T-head is bent out of the sheet metal plane in the form of a roller or a tube, the latter being either round or box-shaped.

It is advantageous if in the lower part, d. H. in the hanger part, at least one slot-shaped incision made from below is made, whereby at least two sheet-metal tabs are formed, which are shaped in the transverse direction of both the lower part of the hanger and the supporting profile so that they alternately grip around the rail head and hold it movably.

The profile hangers formed in one piece from flat material can be designed and manufactured in a simple and very cost-effective manner such that a slot is made in the course of the hanger center axis from the outside, in the direction of the T-head, which divides the lower hanger part into two arms . These are each baked in the opposite direction from the hanger plane or U-shaped, in adaptation to the respective support head of the respective support profile rail. As a result, they enclose the support head in opposite directions when viewed in the longitudinal direction of the mounting rail. In order to ensure good carrying and guiding behavior, it is advisable to design the lower hanger part relatively wide.

A particularly good mounting is achieved if two mutually parallel slots running in the longitudinal direction of the hanger are made in the lower hanger part. The three relatively narrow, resilient arms thus formed encompass the Carrier head alternately and therefore relatively safe, even with a relatively small hanger or arm width.

In order to prevent the support head from jumping out of the arms of the profile hangers, possibly with transverse movements, especially when using T-profile rails, the arms, specifically at the inner incision end or at the arm roots, can be essentially L-shaped in opposite directions to the load-bearing bulges , smaller bulges may be provided. The at least three arms in the direction of extension of the support rail form a push-through / fixing opening into which a locking / fixing pin can be inserted in the profile hanger after the support rail has been attached. As a result, the larger length of the arms makes it easy to insert or snap the support rails into the profile hangers. Then by inserting the locking pins, the elasticity can be reduced by shortening the arms and thus preventing the support head from slipping or snapping out of the arms.

There is thus in the embodiment for T-support rails, for the inclusion of which the arms have to have only relatively small bulges, the possibility of inserting the T-rail with its support head between the arms of the profile hanger, which are somewhat open for the passage of the central section of the profile. This has an advantageous effect if the arms are bent apart at their outer, lower end to form an at least slight entry slope. The hanger can already assume the essentially final position in the anchor rail. There is therefore no need for additional space for the longitudinal insertion of the support profile rails into the profile hangers already suspended in the anchor channels.

For the use of the profile hangers according to the invention in connection with H-support profile rails, their arms are bulged in a correspondingly strongly U-shaped manner, the respective lower, supporting leg being brought substantially horizontally up to the profile center leg. The large transverse width of the arms means that the support head cannot be snapped vertically into them. According to a further embodiment of the hanger, a passage slot which is angular and essentially diagonal to the longitudinal extension can be provided on the lower, horizontal support legs of the arms. In other words, the lower legs are cut off or set back at an angle at the corners adjacent to the incision, as a result of which they can be inserted or retracted. Form a passage slot that allows easy insertion of the support head. By relatively pivoting and mutually parallel alignment of the rail and hanger, the legs of the support head are placed on the lower legs of the arms, which now have an approximate triangular shape. Despite slotted bevels, they still have sufficient stiffness to act safely. Installation is simple by inserting the required number of profile hangers into the anchor channels with the T-head ahead and in the spatial end position and pivoting them through 90 °. A rail is then held under the hangers, which are lifted individually, one after the other and pivoted horizontally so that the passage slot is aligned parallel to the rail. By lifting the rail, the support head is pushed through the hanger slot, 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 rail.

In order to prevent the profile hangers from inadvertently pivoting and thereby causing the rails to fall out of them, two parallel cuts which form three arms can be provided in the lower part of the hanger. Two adjacent arms can be made relatively wide and load-bearing and the third arm relatively narrow and the support head cannot be designed to encompass the underside thereof. The spring tongue formed in this way thus has no carrying function but only a travel limiting function. It closes on its horizontally guided arm section with a hook, which essentially consists of a 90 ° bend leading downwards. When the support head is inserted into the passage slot between the two wide, supporting arms, the hook end of the spring tongue is pushed up in the direction of insertion. After swiveling the hanger and parallel alignment of the support head and arms, the hook of the spring tongue snaps over the longitudinal edge of the support head, abutting against it, which prevents swiveling back. When dismantling, the spring tongue with its hook end must be lifted off the support head, after which pivoting is possible.

In the embodiment with only one incision or only two arms and the insertion slot provided therein, the load-bearing lower legs of the arms can be designed to prevent swiveling and inadvertently pivoting and falling out of the rails.

For example, the lower legs of the U-shape with substantially parallel legs can be deformed further inwards, the support opening tapering in the central zone. When the support head is swiveled in, it must then be acted against the spring force of the lower leg in order to be able to insert it into the support opening. The support head is thus held firmly between the arms of the arms. To make it easier to swivel the hanger in, one is cheap Insertion bevel, for example, by slightly bending the lower leg end to provide.

The supporting legs of the arms can also be profiled, for example have a corrugation, which also partially reduces the cross section of the support opening, so that the support head is prevented from slipping out of the arms by friction. In addition, a particularly secure mounting can be achieved if profiles or corrugations are also provided on the legs of the support head, which correspond to those of the arm legs. Then e.g. engage a recess in the support leg that extends into the support opening in a corresponding groove in the support head in a form-fitting manner. Of course, a wide variety of interlocking arrangements can be provided both in the upper and in the lower arm leg, or in the upper or lower side of the support head leg.

In a further embodiment, the profile hanger formed from flat material can have on its lower part an elongated hole which extends in the longitudinal direction of the support profile rail, while at the same time transverse through holes are provided in the middle leg. The mounting profile rail is attached to the profile hanger by means of a fastening screw with nut, which passes through a through hole in the mounting profile rail and the elongated hole of the profile hanger. It is important for a safe suspension if the elongated hole of the profile hanger has a longitudinal extent (center distance) that is greater than the distance between two successive through holes of the support profile rails.

The flat material profile hanger can also be made in two parts, in such a way that the hanger has a relatively short height has and in the assembled state with the center leg of the support rail is essentially the same plane without the support head coming into contact with the lower edge of the hanger plate. The connection between the two parts is made via an anchor bolt, which on the one hand is essentially S-shaped for hanging in the elongated hole of the hanger and on the other hand is bent in an L-shaped manner in the same plane and in essentially the same direction and extends through one of the through holes of the mounting rail and is secured by a nut or similar. A relatively quick and safe installation is possible in that the hanger plate is inserted into the anchor rail, the anchor bolt is suspended in its elongated hole, the other end is inserted into a through hole in the support profile rail and is screwed onto a nut. The elongated hole provides longitudinal displaceability, which means that mounting inaccuracies can be reliably compensated for.

In a further embodiment, the height of the hanger plate can be designed such that, in the assembled state, it overlaps in height with that of the support rail over a longer distance, so that the elongated hole of the lower section of the hanger extends essentially axially in line with the through holes of the support rail. The parts are held together by a screw leading through a through hole and the elongated hole. At the same time, the profile hanger is bulged in its lower part at the level of the support head so that the head part and elongated hole part of the hanger plate lie essentially in the same plane.

In another embodiment, the profile hanger can be formed from a double sheet with an essentially center-symmetrical design, a one-part or two-part design being possible, depending on whether two identically punched sheet metal parts are connected to each other, or whether a sheet metal piece is folded into a double sheet metal part. At the upper part, from which the T-head is formed, for example by punching, the two sheet metal parts are connected to each other flat, for example by gluing or spot welding, while the lower hanger parts are bent apart to form two legs that slidably encompass the support head of the support profile rail . It goes without saying that, depending on whether they enclose the head of a T-profile or an H-profile, the legs are correspondingly essentially curved (box-shaped) or respectively U-shaped apart or bent symmetrically in opposite directions. It can be seen that this embodiment is very simple and therefore very inexpensive and also very easy to assemble.

It goes without saying that, in particular in the case of using H support rails, corresponding slot-shaped recesses are provided in two opposite side faces of the cover plates, in particular in the case of thick insulation boards, for receiving the support head with attached profile hanger holding legs. As a result, the insulation boards can be placed and pushed on until they lie snugly on the lower profile legs, without a particularly high, material-displacing pushing force being necessary.

In a further embodiment, the profile hanger can have a screw on its upper part, which is installed upside down for ceiling insulation, while it is slidably suspended in the anchor rail via a T-nut or a rectangular nut. The lower hanger part is made of profiled flat material and is suspended from the screw head via a through hole. The hanging part can be L-shaped be folded, one leg for suspension on the hammer head screw or on the screw with hammer or T nut, while the other leg has an opening for slidably receiving the support head.

The lower suspension part can be a flat profile part symmetrically shaped to the suspension direction, with two diverging legs, which depending on the shape of the support head are either essentially box-shaped or U-shaped, the support profile rail is slidably encompassing. Of course, the arms of the suspension part are bent so that there is sufficient space for receiving the screw head between the upper cross part connecting the two legs with the through hole and the upper surface of the support rail.

Of course, instead of the screw with a T or rectangular nut, a hammer head screw with a normal, for example, hexagon nut can also be used, the hexagon nut then being accommodated between the legs of the hanging part.

In addition, there is the possibility of simply assembling these profile hangers, which are assembled from several parts, from these three loose parts and thus to use them or, after their joining, to glue the parts together, so that the desired position of the three parts relative to one another, in particular the position of the hammer head to the holding opening is retained for the support head. The latter, fixed position ensures that the hammer head does not twist in relation to the support head receptacle during assembly and can then slide out of the anchor profile.

Furthermore, a lock nut can also be placed on the screw
be provided, by means of which the hammer head or the nut can be fixed to the previously inserted plate after assembly, ie after pushing on the support profile rail. This prevents the carrier profile rail or the carrier profile rail section which is already holding a plate from being moved unintentionally when further plates are inserted along the same rail. This lock nut consequently represents a simple and effective assembly aid, so that the assembly of the entire insulating wall or insulating ceiling can be carried out by a single person without the need for a further assistant, for example for stopping the end of a mounting rail.

A screw bolt can also be used as an assembly aid, which is pushed through the through holes of two successive support profile rails and firmly connects them to one another. The bolt can be bent L-like at one end, while the thread is provided for the nut at the other end. When assembling this aid, the L-shaped head end is hooked into one of the through holes and brought into a vertical orientation, after which the second mounting rail is pushed over a through hole and held together flush on the outside using a nut (the two profiles, with insulation boards in between). However, this is a lost assembly aid, i. H. it cannot be removed after inserting the panels between the mounting rails.

A more effective and, in particular, more economical assembly aid, since it can be removed and continuously recycled, has two flat-profile shaped pieces which are essentially symmetrical to one another in the assembled state, each of which forms the outer support leg of two successive ones Grip the support rails in a U shape. These have a further leg which is angled in an essentially L-shape to the first gripping leg and extends essentially in the plane of the central leg of the support profile rail (fastening leg) and has a through-hole through which a connecting screw / fastening bolt, for example with a wing nut, is used to fix it accomplished. During assembly, the first fitting is pushed onto the support leg of the first mounting rail and the second fitting is pushed onto the outer mounting leg of the second mounting rail, the screw bolt is pushed through the through holes of the two mounting legs and screwed tight via the wing nut of the assembly aid assembly, which effectively prevents the second mounting rail from moving away is held. This assembly aid is also particularly advantageous since it can be attached and fastened from the outside in any desired or required longitudinal position without taking into account the length of the insulation panels and through holes in the support rails. Depending on requirements and the number available, they can either be left on the rails until the entire ceiling or wall covering has been completed and only then removed, or can be gradually installed and removed again. It goes without saying that, if necessary, they can not only hold two successive support profile rails together, but can, for example, connect the second to the fourth rail, in which case the screw or the fastening bolt must have a correspondingly greater length.

It is also of great advantage if the first or the end support profile rail of a ceiling or wall cover is designed only as a half profile, ie that it is in relation to its middle leg only has protruding leg and profile head configurations on one side, while on the other side the middle leg has a smooth surface. In the case of the production of the support profile rails from a correspondingly curved flat material, it is advantageous if one of the support legs is double-bent, ie is bent back in a U-shape substantially down to the middle leg, forming a narrow insertion slot between the two support leg parts formed in this way. Furthermore, a plug-in profile clip is used, which consists of a substantially U-shaped sheet metal, the legs of which have twice the length of only one support leg and are so closely spaced that they can be pushed onto the bent-back support leg part in a clip-like manner. By pushing on the slide-on support strip / clip thus formed on the underside of the double support leg, a support profile is obtained that has two support legs, like a normal profile. As a result, the last mounting rail with correspondingly narrow panels already inserted, which are not wider than the profile leg, can be pushed onto the adjacent wall, after which the last row of insulation panels is inserted into the space between the last and penultimate mounting profile rails, which is pushed on gradually of the plug-in profile clip are secured against falling out. At the same time, the double leg length of the clip gives the impression that the last mounting rail is identical to the other mounting rails. Dismantling is also greatly simplified since only the clip strip has to be pushed off in order to completely or partially remove the corresponding row from and the first row or the last row of the insulation boards, depending on whether the plug-in strip is pulled off in whole or in part. For this purpose it also makes sense if the clip strip is not in one piece, ie has the total longitudinal extent of the rail, but two or several, shorter clip strips can be pushed next to each other on a rail.

When used as the last support profile rail of a U-profile, which has normal legs and no double legs as support legs, two plug-in profile clips can be used, i.e. a first clip and a second clip, the first clip having half leg lengths in comparison to the second clip and being pushed onto the support leg of the rail, after which the second clip, encompassing this lower leg, is pushed onto the lower leg of the first clip. As a result, the same assembly and visual effect is achieved as in the design of the mounting rail with a double-curved mounting arm.

It goes without saying that in connection with the last half-profiled support profile rail with plug-in profile clip, the profile hanger must also have a correspondingly one-sided design. The respective leg of the suspension plate or the profile hanger, the inner side, d. H. the side on which the insulation boards must be pushed vertically upwards is designed to be flat or non-profiled. These end profile hangers consequently have two legs of differently shaped legs, i. H. one lies unprofiled on the smooth side of the middle leg of the mounting rail, while the other leg is shaped according to the shape of the support head and slidably encompasses it.

The invention has been described essentially using a cover for reinforced concrete ceilings. It goes without saying that the same method and system according to the invention can be used equally advantageously when fastening covers for vertical or inclined walls with insulation or face plates. Known anchor channels can be used here, the inner support leg surfaces of which have serrations. When using profile hangers with lock nuts, the height of the profile hangers is then fixed to the anchor rail, so that a strong compression of the lower rows of plates under the weight of the upper structure is at least partially avoided. Furthermore, it goes without saying that ceiling and wall elements made of a different material, for example, brick, cellular concrete or wood can be covered with the aid of the method and fastening system according to the invention. The anchor channels can be embedded in the corresponding material or attached to it. When attaching the anchor channels, make sure that the insulation boards have corresponding edge recesses for the anchor channels on their upper sides.

The invention is explained in more detail below on the basis of exemplary embodiments with reference to the drawing.

In the fastening system shown in FIG. Insulation boards according to the state of the art, insulation boards 1 are anchored directly to a locally made or cast reinforced concrete ceiling 2 or fastened by means of dowels, screws and possibly corresponding washers. A screed 4 and a conventional covering 5 are then applied to the reinforced concrete ceiling in a known manner.

In the illustration according to FIG. 2, the basic features of the fastening system according to the invention are clearly recognizable, specifically on the basis of a construction with prefabricated reinforced concrete parts. Reinforced concrete ceiling elements 7 are placed on reinforced concrete joists 6, over which a concrete 8 or other covering is poured. The finished ceiling elements 7 have, on the underside, flush with the visible surface, known anchor rails 10, in which profile hangers 11 are suspended in a longitudinally displaceable manner. Support profile rails 12 are attached to the profile hangers 11 and have support legs 13 which project substantially horizontally on their underside. On the upper wing of the support legs 13 insulation panels 1 are placed. The clear height between the support surface of the support legs 13 and the reinforced concrete ceiling 7 is essentially the same as the thickness of the insulation panels 1.

In the fastening system example shown in FIG. 2, the first row of insulation boards is supported on the wall side by a corner support strip 14. This, for example made of L-profile support bar, can be previously dowelled on the wall element or on the support 6 with the fastening leg down. However, it could also be attached with the fastening leg pointing upwards. In order to ensure a uniform appearance of the two opposite corners, however, fastening with the fastening legs downwards makes sense, since the last row of insulation boards can only be fastened with an L-support strip from below, ie with the legs downwards. Further corner fastening options, in which there is no need to anchor elements, are described below in connection with further embodiments.

The profile hanger of the first embodiment shown in FIGS. 3 and 4 consists of flat material, for example sheet steel, which has a T or hammer head 16 at its upper head end. This is offset from the rest of the profile hanger part via symmetrical projections 17, the height of which is designed in accordance with the thickness of the supporting legs of the anchor profile, in such a way that easy hanging and sliding of the profile hangers in the anchor channels is possible.

The lower hanger part 19 is bent in comparison to the upper hanger part 18 and the head 16 by 90 ° from their plane rotated about the axis of symmetry and has a rectangular opening 20 which is opened downwards by a slot 21. In this opening 20, the support head 22, for example a T-support rail 24, is slidably received. The box-shaped opening 20 encompasses the support head 22, while the slot 21 closes with a corresponding clearance around the middle leg 23 of the support rail 24 along a partial height.

5 and 6, the profile hanger 25 is also made of flat material, the hammer head 16 being box-shaped or rectangular in shape from the suspension plane. Of course, this head can also be rolled up in the form of a tube, but this does not result in such favorable carrying properties.

5 that the hammer head 16 is spaced from the rest of the part by projections 17, this distance taking into account the thickness of the support leg 9 of the anchor rail. In the lower hanger part, which here has a relatively large width in relation to the first embodiment, there are two Longitudinal slots 26 are provided which divide the lower hanger part into three spring arms 27, 28, 29. These spring arms are alternately profiled in such a way that they are each bent out at an angle of 90 ° from the center plane of the suspension to each other, then bent back again after 90 ° and then encompassing the support head 22 of the T-profile 24 parallel to the side faces of the support head 22 are guided to finally reach around to reach the middle leg 23. As a result, a support opening 30 for receiving the support head 22 is formed by the spring arms 27, 28, 29 and a fixing opening 31 is formed in the root part of the spring arms 27, 28, 29. In this fixing opening 31, a fixing bolt 32 can be inserted, whereby the movable length of the spring arms is shortened and therefore their elasticity is significantly reduced, so that the support head 22 is secured against slipping out of the support opening 30.

The profile hanger 35 (third embodiment) shown in FIGS. 7 and 8 is constructed in several parts. So its upper hanger part consists of a screw 36 which is suspended via a T or rectangular nut in the anchor rail 10. A lock nut 36 serves to temporarily fix the suspension screw to the anchor rail and at the same time plays the role of an assembly aid. The lower hanger part 19 is formed here from an L-shaped bent flat material, which is supported by a corresponding opening in its short leg 37 on the head of the screw 33, while in its leg 38 hanging vertically here, a support opening 20 with slot 21 for the mounting rail 24 , in the same embodiment as shown in Fig. 4, is provided. After corresponding assembly of the individual parts, the screw 33, the nut 34 and the lower hanger part 19 can be glued to one another in the orientation shown in FIG prevent mutual twisting and thus slipping out of the hammer head from the rail 10. Of course, in this embodiment, the function or design of the screw and nut can be reversed, ie the screw can be a hammer head screw and its head can be hung in the anchor rail, while the nut serves to fix the hanger part 19 on the underside. 9 and 10, a profile hanger 40 is shown in a fourth embodiment, the upper hanger part is substantially identical to that of the profile hanger 35 according to FIGS. 7 and 8. Here, however, the lower hanger part is designed as an essentially symmetrical box hanger part 41, which one Carrier opening 30 for the support head 22 of the T-profile 24 and for receiving the head of the screw 33, and a slot 22 for the central part 23 of the support profile 24 is free. Is in this embodiment as a screw 33 z. B. uses a screw with a hexagon head, then this, as shown in FIG. 10, can be positively supported on the side legs of the box hanger profile 41 so that the screw and box hanger 41 cannot twist with respect to one another. In this case, only an anti-rotation insurance between screw 33 and T-nut 34 must be provided, for example by gluing or the like. In this embodiment, too, a lock nut 36 can be used as a fixing or assembly aid.

In Fig. 11 it is shown how the profile hanger 40 can be hooked into an anchor rail 10 in a simple and quick manner and in turn a T-profile 24 can be suspended from it by inserting it. The assembly steps I.-IV. For suspending the rails are shown in succession essentially from left to right. At I. arrow 42 shows the first insertion movement, via which a profile hanger 40 with T-nut or hammer head 34 and support opening 30 in the longitudinal direction of the Anchor rail 10 is inserted between the support legs 9 of the anchor rail until the head 34 comes to rest overall over the support leg, as shown in II. Then we bring the profile hangers with T-head 34 and support opening 30 into an orientation transverse to the longitudinal orientation of the anchor rail 10 with a 90 ° rotary movement shown by arrow 43 and lower them until the support 34 rests on the support leg 9. Then according to arrows 44 and 45 in III. a T-support rail 24 with its support head 22 inserted into the support opening 30 of the profile hanger 40. In position IV. The finished suspension of the support profile rail 24 is shown in anchor rail 10. Now the insulation boards can be placed on the support legs 13 of successive support profile rails 24 and their corresponding pushing in the longitudinal direction of the anchor rail 10.

12 shows the fully assembled state of the fastening system. It can be seen that 2 anchor profiles 10 are embedded parallel to each other in the reinforced concrete ceiling. Profile hangers 40 are suspended in these anchor profiles 10, and T-profiles 24 are inserted into them. On the support legs 13 of the support rails 24 lie the insulation panels 1, which are simultaneously on their other side against the reinforced concrete ceiling 2.

13 shows a further assembly step, namely the assembly of the last row of plates. For this purpose, the last support rail 46 is provided on one side only with a support leg 13. The half-sided support rail 46 is formed from flat material, the support leg 13 of which has a U-shaped double configuration. The upper support leg part 47 is turned back by 180 ° to a lower support leg part 48 between the support leg parts 47, 48, a slot-shaped space / insertion slot 49 releasing. Furthermore, a strip-shaped plug-in profile clip 50 is provided, which consists of a U-shaped flat material part with two closely spaced legs 51, 52. The clip 50 is inserted with its upper leg 51 into the slot 49 up to the stop on the bending edge between the leg parts 47, 48. Since the length of the legs 51, 52 of the clip 50 is essentially twice as long as the length of the support leg parts 47, 48 and thus the leg 48, which is completely covered by the long leg 52, the clip 50 stands out by half the leg length amount Middle leg level of the support profile rail 46, so that the impression of a normal T-support profile is created. In order to ensure complete lateral coverage of the leg part 48 by the clip 50, it is useful if the upper leg 51 is at least shorter than the leg 52 by the material thickness.

From the fully assembled situation of an insulation board 1 with clip 50 inserted underneath it, which is further shown in FIG Plate rests on the ceiling, after which the clip 50 is pushed onto the rail 46, supporting the insulation board 1.

From Fig. 13 it can also be seen that before inserting the last insulation board and correspondingly pushing the last support rail, between the wall and the corresponding side of the support rail 46, a narrow insulation board part 53 with the same width dimension as the support profile leg is placed, after which the support rail profile 46 to for a full support with the insulation board part 53 on the wall or on the support 6 pending. Only then is the actual last row of insulation boards inserted and fixed in place by clip 50.

14 and 15, a profile hanger 55 (fifth embodiment) is shown, which essentially consists of a plate-shaped upper hanger part 18, in which a T or. Hammer head 16 is incorporated. At the lower end of part 18 there is an elongated hole 56 extending in the direction of the longitudinal direction of the hammer head. An anchor bolt 57 is suspended in this via its upper, S-shaped bent part. With its lower, essentially L-shaped bent part, which has a threaded part 58 at its end, the anchor bolt 57 is inserted in a through hole 60 of a T-shaped profile strip 24 and held in place by a nut 59. Washers 61 on both sides of the middle leg 23 also allow a straight suspension of the support rail 24. In particular from Fig. 14 it can be seen that the distance between the through holes 60 is at most as long as the length of the elongated hole 56, so that the suspension over the profile hanger 55 can always be done with an essentially vertically hanging anchor bolt 57.

Fig. 16 shows a perspective and partial exploded view of the assignment of the individual fastening system parts using a profile hanger 55. Instead of a wing nut, a hexagon nut is used here, which means that less space is required, so the rail has to be pressed with less force on the preceding plate.

17 and 18 a further profile hanger (sixth embodiment) is shown. This is formed in one piece from flat material and also has a hammer head formation 16 on its upper part and on its lower part Slot 56 on. In the middle part, a trough-like bulge 64 is formed, which leads around the support head 22 of the support profile rail 24 or bulges it over. A screw 62 is pushed through a bore 20 in the middle leg of the rail 24 and the elongated hole 56, to which a nut 63 is screwed, connecting the profile hanger 65 to the rail 24.

In Fig. 19, a fastening system using a profile hanger 65 is shown in perspective and at the same time in an exploded view, wherein it can be seen that the profile hanger is displaceable on the one hand in the anchor rail 10 and, on the other hand, is screwed to the support rail 24 with a compensatory displacement via the elongated hole 56.

20 and 21, a profile hanger 39 is shown, which has an essentially one-piece, but two-part design, two symmetrical parts being permanently connected to one another. These parts also have an upper hanger part 18, with a molded or stamped T or. Hammer head 16, while the lower hanger parts 19 are cheek-shaped, encompassing the support head 22 of the T-support rail 24. The two symmetrical parts can be held together on the hammer head part 16, for example by gluing or pressure welding. The lower leg part ends are spaced apart from each other by a slightly larger amount than the thickness of the central leg of the rail profile, leaving a slot 21 between them. Overall, the leg openings are dimensioned so that the support head 22 of the T-support rail 24 can be easily pushed in and on.

The profile hanger 54, gem. 22 and 23 is made in one piece, ie formed from a single sheet metal stamping.

In this case, a downwardly open slot 26 is made in the lower hanger part 19, along the hanger center axis, which extends into an upper, flat transverse part 99 or (not shown here) into the neck part 100. The arms 27, 28 formed by the slot 26 are bent out in a cheek shape in the opposite direction from the hanger plane, are essentially non-resilient and encompass the support head 22 of the T-rail 24. To ensure reliable holding or carrying, the profile hanger 54 or its lower part 19, overall much wider than, for example for profile hanger 39. The use of a thicker sheet is also indicated.

24 to 34 show a fastening system according to the invention using H-support profile rails in connection with correspondingly designed profile hangers 66, 98, 101 and 102.

24 and 25 is composed of two identical sheet metal parts, similar to the profile hanger 39 according to FIGS. 20 and 21 (for T-profile), only that the two parts 67, 68 are bent more U-shaped, in Adaptation to the support leg 69 of the H profile 70.

The profile hanger 98 shown in FIGS. 26 and 27 has a structure similar to that of the profile hanger 54 according to FIG. 22 and 23, only that here the slot 26 extends into the neck 100 of the hammer head 16 and the arms 27 and 28 of the parts 67, 68 are substantially extended, U-shaped, for the load-bearing accommodation of the support head legs 69 .

The profile hanger 101 shown in FIG. 28 merely represents a constructive variant of the profile hanger 98 and has a higher transverse part 99. Here's the one-piece Embodiment of the profile hanger and its support leg design, particularly well recognizable.

FIG. 29 shows a hanging process in steps I. to IV. For a profile hanger 66 and an H-support profile rail 70 (similar to that shown in FIG. 11 for profile hanger 40 and T-support profile rail 24). Here too, the profile hanger 66 is pushed vertically upward into the anchor rail parallel to the extension of the anchor rail 10 in the longitudinal direction of the head, rotated through 90 ° in accordance with arrow 43 and placed on the support legs 9 of the anchor rail 10. Then the H-support profile rail 70 is inserted into the support opening 30 of the profile hanger 66 in accordance with the arrows 44 and 45, in order to serve, as shown under IV., In an optimal shift-receiving state for support or for pushing onto the insulation panels placed on the previous profile part.

In Fig. 30 a similar assembly and training situation of the last row of insulation panels is shown as in Fig. 13. The last support profile rail is designed as a U-support rail 71, which is formed from flat material, the lower support leg, as with the T 13, is bent back in a U-shape and thus has two leg parts 47 and 48, leaving a slot 49 uncovered. Here too, a clip 50 with the upper leg 51 is also inserted into the insertion slot 49, the lower leg 52 covering the leg part 48 of the rail 71 as a visible strip.

The support profile rail 71 is used in connection with a profile hanger 72 which is formed at least on one side (profile hanger part 68 is identical to the profile hanger 66). Instead of part 67, however, there is an unprofiled, flat hanger part 73 with the profiled one Part 68 connected. The part 73 lies flat on the outside of the middle leg of the profile rail 71, which also ensures good carrying and sliding properties. In this embodiment of the support rail 71 and the profile hanger 72, an insulation board part 74 is inserted on the wall side or towards the support element 6, the width of which is approximately equal to the length of the support leg 47. It fills in the height between the underside of the head leg 69 and the support leg 47 of the profile rail 71, while another insulation board part 75 fills the gap between the top of the support head leg 69 and the ceiling surface.

FIG. 32 shows how an insulation panel 1 is slid onto a first support profile rail 70 shown on the left in the figure, which is suspended in an anchor rail 10 via a profile hanger 66. The insulation board, which is provided on both sides with receiving slots 76 for the support head legs 69, is lifted vertically up to the abutment on the ceiling surface in the 1st step, according to the arrows 77, after which in the 2nd step the board 1 according to the arrows 78 on the first Support rail 70 is pushed. Then the already prepared second rail 70 (shown on the right) is pushed onto the panel until its support leg (13) fully engages under the lower edge of the insulating panel 1.

31 and 33 show, in perspective and in partial section, a fastening system according to the invention using H-mounting profile rails 70 and profile hangers 66, the pushing-on process of the mounting rails 70 in particular being more clearly recognizable.

FIG. 34 shows a profile hanger 102 (11th embodiment), which in principle corresponds in structure to the hanger 101 from FIG. 28. Graduate 102 has two vertical ones Incisions 26, but which are not evenly spaced. Thus, part 67 consists of a wide arm 27 and a narrow spring tongue 103, while part 68 consists of only one arm 28, which is of the same width as the arm 27. The arms 27, 28 are on the with respect to the intermediate incision 26th opposite corners are chamfered or cut off at an angle to the longitudinal alignment of the hanger so that parallel cutting edges 104 are provided which expose a passage slot 105 between them. The slot 105 has a slightly larger width than the support head 69 of the H-profile rail 70 to be inserted. In order to obtain a sufficient slot width, the support leg can be cut out at an angle beyond the bending edge, as a result of which a step 107 is formed in the curved part of the arms. The spring tongue 103 has at its outer end a hook 106 which consists of an essentially 90 ° curved part which supports the support head leg 69 in the transverse direction. The spring tongue is designed to be relatively narrow, so that it is vertically elastic.

35 and 36 a further profile hanger 80 is recorded. This is formed in two parts, the upper hanger part 18 having essentially the same design as the profile hanger 35 (FIGS. 7, 8) and 40 (FIGS. 9, 10), that is to say with a screw 33, T-nut 34 and lock nut 36 The lower hanger part 81 is suspended in essentially the same way as the hanger part 41 of the profile hanger 40 (FIGS. 9 and 10), but the leg design is adapted to the head legs 69 of an H-shaped profile rail 70. The lower hanger part 81 is here an axially symmetrical molded part, which on the one hand has an insertion opening 30 for the head legs and on the other hand a further bulge 82 for receiving the head of the screw 33.

37 shows an assembly aid 85 which consists of two essentially identical shaped pieces 86. These have two L-shaped legs 87 and 88. The legs 87 encompass the respective outer support legs 13 of two successive support profile rails 24 in a U-shape, while the legs 88, which are essentially parallel in the suspension plane and at the same time mutually parallel, are penetrated by a screw 83 which is screwed via a nut, for example a wing nut 84. This assembly aid 85 can be attached and removed again very quickly, since only the two shaped pieces 86 are pushed onto the outward-pointing legs of two successive profile rails and the two lower legs 88 have to be screwed together until the two mounting rails are essentially immovable hold the insulation board in between. If the ceiling is fully laid out or the laying or covering process has progressed far, some of the previous assembly aids can be removed simply and easily by loosening the nuts 84 and removing the corresponding first shaped piece 86 and then the second shaped piece 86 with screw 83 . They can be reused in subsequent assembly rows until all assembly aids 85 must be removed after the entire insulation ceiling has been completed.

The further assembly aid 90 shown in FIG. 38 consists of a bolt 89 which, through its two ends, passes through through bores 60, which are aligned with one another, of two successive support profile rails 24. One end has an L-shaped bend 91, while the other end is fixed by a nut 92. This installation aid can no longer be removed after installation and is arranged between the end faces of two plates.

39 and 40 show how, for example, an installation pipe 93 can easily be taken into account in the subsequent fastening of the insulation panels in such a way that a visually good result is achieved without special material and insulation losses. This is realized in that the plate, through which the pipe 93 has to be passed, is cut transversely to its longitudinal extent in such a way that two plate parts 94 and 95 are formed, into which corresponding semicircular cutouts with the pipe dimensions are made. In particular, by using assembly aids 85, the two plate halves 94 and 95 can be correspondingly applied to the pipe, the subsequent rail pushed in and held in place by the assembly aid 85.

41 shows how, for example, the fourth row of insulation boards is inserted or fastened from above in the illustration. The procedure is as follows:

96.1

First the next support rail is installed, ie suspended from the corresponding profile hangers in the anchor rails of the reinforced concrete ceiling.

96.2

Then a first insulation board is held to the concrete ceiling and inserted between the support rails up to the wall / support and at the same time firmly pushed onto the previous support profile rail.

96.3

The pre-assembled, subsequent support profile rail is pushed onto this first plate until its support leg carries the plate.

96.4

An assembly aid 85 is now attached between the preceding and the subsequent support profile rail by being placed on and screwed on. These Auxiliary device prevents the already assembled plate from falling out when the next connecting plate is installed.

96.5

The next insulation board is inserted between the two mounting rails 24, 70 and pressed tightly against the end face of the board that has already been installed. If there is no step rebate on the underside of the panel, it is recommended that a front cover joint profile be used to achieve a pleasing look.

96.6

The following rail profile is pushed close against the plate.

96.7

A second assembly aid is attached.

96.9

Analogous to 96.6.

96.10

Assembly aid one (96.4) is removed at position 4 and attached approx. 40 cm in front of the front edge of the penultimate plate. This enables the mounting rail center distance on the last plate to be increased to such an extent that the last plate can be fitted without problems.

96.11

Fit the plate.

96.12

Push the rail profile onto the plate.

Then the next mounting rail is mounted and proceeded in the same way as under 96.1 to 96.12, with the last mounting rail used being a rail and profile hanger design, as shown in FIGS. 13 and 30, i.e. with plug-in profile clip 50, which is attached as the final assembly steps will.
