Description

The invention relates to a holding device for receiving a vertical load of a surface element, a method for producing a Haltevor direction for receiving the vertical load of a surface element and the use of such a holding device on a curtain wall with at least one side rail profile and at least one cross member profile.

Such holding devices are known in principle from the art. In particular, in highly insulated curtain walls, which are formed of longitudinal and transverse beam profiles and field-wise surface elements, in particular glazing elements occur by the relatively large mass of such coming to use surface elements on large supporting forces, which via corresponding fixtures, usually retaining strips in the profiles must be initiated. In recent years, triple glazing is increasingly used in such curtain walls in order to further increase the insulating effect. This again results in increased payloads whose supporting forces must be introduced into the profiles.

In order to cope with such high support forces, usually holding devices made of metal, in particular made of aluminum are used. Through the use of such good heat-conducting materials such as aluminum, however, the insulating effect of the multiple glazings used, ie in particular the insulating effect of the triple glazing, repealed on such curtain walls, at least in the sub-areas, resulting in relation to the entire building a worse energy balance.

It is therefore the object of the present invention to develop conventional holding devices for receiving a vertical load of surface elements in such a way that the insulating effect is improved.

According to the invention, this object is achieved by a holding device according to independent claim 1 and a method for producing a holding device according to independent claim 12.

In particular, the object is achieved in that a holding device for receiving a vertical load of a surface element, in particular a glazing in a curtain wall, made of castable plastic with reinforcing fibers having a fiber content of more than 50%, preferably of about 60%.

With regard to the method according to the invention, the object is achieved by providing a method for producing a holding device for receiving the vertical load of a surface element, which method comprises the step of providing a casting material of castable plastic with reinforcing fibers having a fiber content of more than 50%, Preferably, about 60%, more preferably polyamide with a glass fiber content of about 60%, the step of providing a mold for at least one part for installation on at least one cross member profile and the step of casting the at least one part for installation on the at least one cross member profile from the casting material in the casting mold.

Characterized in that the holding device according to the invention is made of a poor thermal conductivity material, namely of a plastic-reinforcing fiber mixture, the insulating effect, for example, a curtain wall, on which such a holding device according to the invention is used, significantly improved. In particular, compared to the prior art in the inventive solution now only a negligibly small heat conduction along the holding device, so that in particular in multiple glazings such as triple glazing, the advantageous Insulating effect is no longer deteriorated in the holding devices.

Due to the fiber content of more than 50%, preferably of about 60%, in the plastic reinforcing fiber mixture, the holding device according to the invention is also sufficiently resilient that relatively large and heavy surface elements can be effectively and safely supported.

Due to the castability of the plastic, such a holding device can be produced particularly easily in the casting process. In particular, with regard to other plastics or plastic reinforcing fiber mixtures, the possible shaping of the holding device according to the invention is not restricted by otherwise necessary extrusion processes to possibly unfavorable forms.

With regard to the method according to the invention, simple production is ensured by the fact that a plastic casting compound having a reinforcement fiber content of more than 50%, preferably about 60%, is made available and then a part of the holding device is cast from the casting compound. Compared to conventional solutions in particular, no elaborate and shaping limiting explosion process must be used. This makes it possible to adapt the shape of the holding device obtained by the method according to the invention the increased Traglastan requirements.

Advantageous developments of the solution according to the invention are specified in the dependent claims.

Relative to the holding device according to the invention, it is provided according to one aspect of the invention that the castable plastic is polyamide. This results in the particular advantage that an easily available, inexpensive material with excellent insulation properties for comparatively simple manufacture of a holding device according to the invention can be used.

According to a further aspect of the invention it is provided that the reinforcing fibers are glass fibers. The fact that glass fibers have no negative impact on the insulating effect of the plastic used, for example the Polyamides have, are available inexpensively and have excellent load-increasing effects, can be obtained in this way easily and inexpensively a highly resilient holding device according to the invention.

According to a further aspect of the invention, it is provided that the holding device has at least one horizontal part in the installed state. The horizontal part, in turn, has a fastening region which cooperates, at least in regions, with a cross member profile in such a way that, in its installed state, the holding device can absorb a vertical load of more than 200 kg, preferably more than 350 kg.

Compared with conventional holding devices, the load according to the invention thus not only has a comparably large load capacity, but also a significantly improved insulation effect.

By the at least partially cooperation of the mounting portion of the horizontal part with the cross member profile results in an optimal initiation of the supporting forces, i. the vertical loads, so that comparatively large and heavy surface elements, such as multiple glazing, are held by the holding device safely and reliably. Nevertheless, only a horizontal part is provided for loads of this magnitude, which makes the holding device compact and relatively cheap.

According to a further aspect of the invention it is provided that the holding device additionally has at least one vertical part in the installed state. The vertical part in turn has a mounting area which cooperates at least partially with a side rail profile such that the holding device in the installed state can accommodate a vertical load of more than 350 kg, preferably more than 650 kg.

The additionally provided vertical part results in a further improved distribution of the supporting forces to be introduced into the entire profile construction, which makes it possible to accommodate a further higher load of the surface elements of the order of, for example, about 700 kg.

According to a further aspect of the invention it is provided that the at least one vertical part in the installed state above the at least one horizontal Part is arranged. This makes it possible, even in the bottom region of the profile arrangements, on which the holding device according to the invention is used to achieve at least partial introduction of the supporting forces in the side rail profile. In this case, an introduction takes place above all via tensile forces, which is why longitudinal and / or transverse fastening means can be used for fastening the at least one vertical part and for transmitting these tensile forces. Such fastening means can be locked, for example, to correspondingly formed counter-elements on a side rail profile.

Alternatively or additionally, however, it can also be provided that the at least one vertical part is arranged below the at least one horizontal part in the installed state. As a result of the essentially occurring compressive forces-in contrast to the tensile forces when arranging the at least one vertical part in the installed state above the at least one horizontal part-this results in a simpler and, as a result, more reliable design. In order to fix and position a vertical part arranged below the at least one horizontal part, longitudinal and / or transverse fastening means can again be provided here as well.

According to a further aspect of the invention, it is provided that the at least one horizontal part and the at least one vertical part are connected to one another by means of a connecting part.

This results in the particular advantage that the holding device is easy to use at the installation site on the profiles. By providing such a connecting part, an integral cohesion between the at least one horizontal part and the at least one vertical part is also ensured, which results in an increased reliability when receiving the loads.

According to a further aspect of the invention, the connecting part has at least one drainage channel for dewatering at least a portion of the horizontal part. Such a drainage channel leads to the surface elements running liquid, such as rainwater, initially horizontally away from the surface element and thereby allows a field-wise drainage of the individual elements.

At the same time this ensures that no or only a negligible amount of moisture can accumulate on the horizontally extending parts, whereby optics and durability of the particular held surface elements are improved.

According to a further aspect of the invention it is provided that the at least one horizontal part, the at least one vertical part and the connecting part are integrally formed. It should be noted here that it is also possible with a connection of two horizontal parts by means of the connecting part, to provide no vertical part and form only the two horizontal parts and the connecting part in one piece.

Such a one-piece construction reduces the number of joints in the individual parts, which increases the possible load again. In addition, a simple production of the holding device in the casting process with integral connection is possible by the one-piece construction.

According to a further aspect of the invention it is provided that the surface element is a multiple glazing, preferably a triple glazing. Due to the special design of the holding device according to the invention, a comparatively large surface element can be held securely and reliably with a large mass resulting from the multiple glazing, in particular triple glazing.

With regard to the method according to the invention, according to a further aspect of the invention, it is provided that the casting mold is a casting mold for an integral part comprising at least one horizontal part, a connecting part and optionally additionally at least one vertical part.

Such a one-piece construction reduces the number of molds needed for the parts as well as the number of casting steps required. In addition, the overall casting process is simplified as a result.

According to a further aspect of the invention, it is provided that, after the provision of the casting mold, a part which is undesirable for the subsequent casting operation in the casting mold is cut out by area-wise sealing of the casting mold against the casting mass. It is provided in particular that at a Mold with two horizontal parts, at least one vertical part and a connecting part, the vertical part or the vertical parts are recessed, so that in a subsequent casting process, a one-piece, integral part of two horizontal parts and the connecting part results.

Just as well, however, other case-specific recesses are possible, for example, a sealing of only one of two vertical parts in order to obtain a largely T-shaped holding device.

As a result, the flexibility in the manufacture of holding devices with the method according to the invention increases considerably, since individual parts of the casting mold can occasionally be omitted depending on the requirements.

According to the invention, the use of such a holding device is provided on a curtain wall with at least one side rail profile and at least one cross member profile, wherein the holding device is designed to receive the vertical load of a surface element of the curtain wall, in particular a glazing, preferably a triple glazing of the forehand wall.

In the following, the holding device according to the invention will be explained in more detail with reference to a drawing.
