FIELD OF THE INVENTION [0001] for fastening the heat-insulating panels to the walls, comprising a fixing stem and preferably a head fitting to the fixing stem.

Increasing demands on thermal engineering are increasing the demands on the thermal insulation of buildings. Existing and newly constructed walls are often covered with tile insulation to ensure proper insulation.

The insulation boards can be fixed to the walls in various ways. so e.g. using adhesives or bitumen and mechanical fasteners. Mechanical fasteners provide the highest fastening strength.

Examples of such mechanical fasteners are those disclosed in Hungarian Patent Nos. T / 43,684 and T / 43,685. Their essence is that the plastic body and head are connected by stems with longitudinal slits. As with other known solutions, the fastener may be stabilized by a fastening screw such that, when the fastening screw is screwed in, the torso moves towards the head and thereby secures the fastener by stretching the stems.

A common disadvantage of both solutions is that their fixing requires the use of a metal fastening screw, which creates a thermal bridge at the place of the fixing, which reduces the efficiency of the thermal insulation.

SUMMARY OF THE INVENTION It is an object of the present invention to provide a fastening assembly capable of overcoming the disadvantages of the prior art to fasten various board materials to larger surfaces in a heat-free and optionally retractable manner.

The idea of the present invention is based on the discovery that a fastening fixture according to the object is obtained by cleaving the body of the fixture with an opening, and a tensioning piece which is capable of penetrating the edge of the opening is temporarily secured.

In accordance with the object of the invention, the fastening assembly according to the invention is used primarily for construction applications, in particular for sheet-like elements, e.g. for securing the heat-insulating panels to the walls, comprising a locking shank and preferably a head fitting to the fixing shank, is formed by a torso with at least a partially inclined rib at one end of the fastening shank and a tongue penetration stretching tension is temporary, eg. attached by means of an injection molding.

A further feature of the invention may be that the torso opening and the tension member are both wedge-shaped and the inner wall of the opening is provided with ribs.

In a preferred embodiment, a protrusion with an oblique rib, thread or thread is connected to the torso body by inserting a central member.

In another embodiment, the inclined ribs of the torso and the projection are oppositely inclined.

In a further embodiment, the middle member and the projection preferably have the same diameter and the torso diameter exceeds the diameter of the middle member and the projection. either with a locking flange and slots or with a neck socket thread and a flange with keyholes.

In any embodiment, the torso forms a joint with the head, and the head is a snap-fit fastener, e.g. consisting of a wire holder.

The greatest advantage of the fastening assembly according to the invention is that it can be used to fasten various large board materials without heat bridging.

It is also advantageous that, due to the variety of embodiments, the fastening assembly can be used in almost all applications, can be retracted if necessary, and its production can be achieved by simple mass production.

The invention will now be described in more detail with reference to the drawings. The attached drawings show

Fig. 1 shows a possible embodiment of the fixing leg of the fastening assembly (1) according to the invention. The locking leg (1) has a projection (11), a central member (12) which extends and a body (13) attached to the middle member (12).

The diameter of the protrusion (11) and the middle member (12) is the same in this example, and the diameter of the strain (13) exceeds the diameter of the middle member (12) and the protrusion (11). In this embodiment, the projection (11) is provided with ribs (11a) of oblique configuration.

The strain (13) has ribs (13a) of oblique configuration, the deflection of which is opposite to that of the ribs (11a) of the projection (11). The strain (13) is split with the opening (13b). A tension piece (2) suitable for penetration into the flange (13c) of the opening (13b) is secured by the temporary connection (2a). The temporary connection (2a) may be, for example, an injection fiber.

Both the opening (13b) of the body (13) and the tensioning piece (2) are wedge-shaped. In this embodiment, the inner wall (13d) of the opening (13b) has ribs (13e).

Fig. 2 shows a head (3) for the anchoring rod (1) according to Fig. 1. The head (3) has a flange (3a) to which the neck (3c) is attached. The neck (3c) is provided with a seat (3d) having a retaining flange (3e) and a slot (3f).

Figure 3 illustrates a further embodiment of the locking leg (1). This embodiment differs from the embodiment described in relation to Fig. 1 in that the projection (11) is provided with a thread (11b) instead of the oblique ribs (IIa) and the inner wall (13d) of the opening 5 (13b) includes ribs (13e).

Fig. 4 shows the arrangement of the head (3) for the anchoring rod (1) according to Fig. 3. In this embodiment, the head (3) also has a flange (3a) and a neck (3c) attached thereto, but the neck (3c) is provided with a thread (3a) instead of a locking flange (3e). ) and the flange is completed with the keyholes (3b).

Fig. 5 illustrates another possible embodiment of the locking leg (1). In this embodiment, the middle member (12) extends into the threaded stem (11c) forming the projection (11) and the strain (13) has the same configuration as described in FIG.

Fig. 6 shows an embodiment of the fastening assembly 20 according to the invention, in which the fastening leg (1) and the head (3) are integrated. The anchor rod (1) is formed by the strain (13) which forms a joint with the head (3). The structure of strain (13) is identical to that described in Figure 3.

Fig. 7 shows a further embodiment of the fastening assembly according to the invention, in which the fastening leg (1) is also formed by the body (13) which is integrated with the head (3) for the snap-on fastening conductor (3h). The structure of the strain (13) is also the one shown in Figure 3.

By using the fastening device according to the invention, a hole of a size corresponding to the body (13) of the fastening rod (1) is made through the heat insulation to be fastened.

The locking rod (1) is then inserted into a hole of sufficient depth. After insertion, striking the shank (1) strikes the bottom of the bore (2) to break the temporary threaded injection molding (2) and penetrates into the opening (13b) as the shank (1) moves inward.

The tensioning piece (2) entering the opening (13b) expands the body (13) and secures it to the base. The oblique ribs (13a) of the body (13) facilitate this attachment.

After placing the locking rod (1), pressing the head (3) creates the heat insulation locking. In the event of possible deformation of the insulation, the position of the insulation can be re-stabilized by further pressing the head (3).

In the embodiments having the head (1) integrated with the head (3), the attachment assembly can be used in a similar manner, however, the stabilization of the attachment assembly can be achieved directly by applying a force to the head (3).

The fastening assembly of the present invention is advantageously used for fastening plate-like elements to walls, especially when heat-free fastening is a primary requirement.
