Description

The present invention relates to a profile for a dry structure, comprising a first circumferential edge and a second circumferential edge connected to each other via a belly plate.

Such a profile is known, for example, from DE 10216675 (B4). The profile forms a support structure and serves to accept flat structural panels, such as gypsum plasterboard. A flat structural panel is fixedly fastened to the periphery of the profile.

Therefore, the profile is usually formed from metallic material. In this case, it is a problem that metal materials often have good heat conduction properties. When performing thermal isolation by walls constructed using profiles, the problem is that the metal profile extending from one side of the wall to the other forms a thermal bridge through which considerable heat transfer There is a problem that this may occur.

In the case of the previously known profile, the separation of the two peripheries is brought about by a separation gap in which an elastic material is introduced and connected to the peripheries by an adhesive connection.

A further problem is that sound is transmitted through the profile and the propagation of sound within the profile is unimpeded.

The aim of the invention is to provide a profile for dry structures, which allows thermal separation of the two peripheries and is easy and cheap to manufacture.

This object is achieved by the features of claim 1. The dependent claims point to advantageous embodiments.

To achieve this objective, the ventral plate is formed from ventral plate elements that are connected to the first circumferential edge and the second circumferential edge in a form-fitting manner. Due to the fact that the vent plate is formed from a plurality of vent plate elements, a thermal separation of the two peripheries is already achieved, independent of the choice of material of the vent plate elements. Due to the fact that the belly plate element is connected to the first circumferential edge and the second circumferential edge in a form-fitting manner, the profile can be manufactured particularly easily and inexpensively. It is only necessary to fasten the belly plate elements to both peripheries. In particular, there is no need to provide additional connection means or to create adhesive connections between the elements.

Furthermore, because the profile includes multiple parts, it is advantageous that sound propagation within the profile is reduced, so that improved sound separation is achieved.

The first circumferential edge and the second circumferential edge can each include a fastening portion, into which an opening is introduced, and the belly plate element is fastened into the opening. The fastening parts are therefore preferably formed as strips and arranged relative to each other in a plane. Multiple openings are therefore introduced within each fastening portion. This can preferably be implemented in the form of a pattern of holes with circular openings at regular intervals. This allows flexible placement of the ventral plate elements within the two peripheries. For example, depending on the expected loading situation, the number of belly plate elements can be increased or decreased to form the profile. The aperture further improves the sound isolation properties of the profile.

The abdominal plate element preferably has the form of a plate. With this design, the belly plate element is formed as a flat element and can therefore be manufactured simply and inexpensively.

The belly plate element is preferably provided with a form-fitting element, and the belly plate element is connected to the fastening portions of the first circumferential edge and the second circumferential edge via the form-fitting element. The form-fitting element thus engages within the opening of the fastening part such that the belly plate element is fixedly connected to the fastening part of the first circumference and the second circumference.

The form-fitting element can comprise a bore or a fastening element, the fastening element being introduced into the bore. Accordingly, the belly plate element is arranged on one side of the peripheral fastening part, and the fastening element is arranged on the other side of the fastening part and passes through the peripheral opening into the bore of the belly plate element. stand out.

The fastening element is therefore preferably fastened into the bore of the belly plate element by a snap-fit connection. For this purpose, the bore of the belly plate element on the side facing away from the fastening element is provided with a cross-sectional extension. The fastening element then comprises a projection, at the free end of which an elastically tiltable conical cross-section extension is arranged. The cross-sectional extension deforms when pushed into the bore and becomes fixedly secured within the cross-sectional extension. In this way, the belly plate element is fixedly fastened on the first circumferential edge or on the second circumferential edge by means of the fastening element.

According to an alternative embodiment, each belly plate element can be provided with a form-fitting element in the form of a bore and a projection, in each case two belly plate elements being assigned to each other. In this embodiment, a separate fastening element is omitted. For fastening purposes, the two ventral plate elements are preferably arranged back to back and receive fastening portions of the first and second peripheries. This results in a particularly mechanically stable connection and a particularly mechanically stable profile.

The bore and projection of the form-fitting element are therefore preferably designed in a matching manner. For joining purposes, the protrusion of the belly plate element engages within the bore of the other adjacent belly plate element. The protrusion thus passes through the opening in the peripheral fastening portion.

The ventral plate element may comprise a first edge assigned to the first circumference and a second edge assigned to the second circumference, and the bore and the protrusion each have a first edge assigned to the first circumference and a second edge assigned to the second circumference. 1 edge and a second edge. Furthermore, the bores and projections are preferably arranged such that the bores and projections on the first edge have point symmetry with respect to the arrangement of the bores and projections on the second edge. In this embodiment it is advantageous that a single embodiment of the abdominal plate element is sufficient to form the profile. For fastening purposes, the first ventral plate element is disposed within the two peripheral openings and the second ventral plate element is fastened onto the first ventral plate element in a mirror-symmetrical and back-to-back manner. The protrusions of the two ventral plate elements thus each pass through the two peripheral openings. Furthermore, the protrusion of one belly plate element engages within the bore of the other belly plate element. Profiles can therefore be manufactured quickly and inexpensively. Furthermore, only one single forming tool is required to manufacture the belly plate element.

The ventral plate element is preferably constructed from a non-metallic material, especially a synthetic material. It is therefore preferable to use synthetic materials that can be injection molded. In this case, it is advantageous that synthetic materials are inexpensive. Furthermore, synthetic materials have advantageous thermal properties. Synthetic materials have a relatively low thermal conductivity, which affects the thermal separation of the two peripheries. Synthetic materials also have sound isolating properties, especially compared to metallic materials.

In addition to the use of synthetic materials, the use in the form of composite materials, for example fiber-reinforced synthetic materials, is also particularly contemplated.

The first peripheral edge and the second peripheral edge are preferably formed from a metallic material. This allows, in particular, the processing of the profile or the attachment of wall elements to it using conventional means known from dry construction technology.

A fastening flange for receiving a dry construction panel is formed from a first perimeter and a second perimeter. The periphery is therefore preferably formed such that the flat element is arranged on the periphery, and two adjacent wall elements can also be arranged edge to edge on the periphery. The wall elements are preferably fastened by threaded connections. Drywall screws can be used for this purpose.

Preferably, the profile is formed as a C-shaped profile. Such profiles are commonly used in dry construction.

The wall according to the invention comprises a plurality of profiles according to the invention and at least one flat structural panel fixed on fastening flanges of the profiles. Preferably, flat structural panels are fixed on both sides of the profile. Since both peripheral edges of the profile are thermally separated by separately formed belly plate elements, a wall with good thermal insulation properties is produced.
