Description

The invention relates to a facade construction unit for fastening a facade panel to the other elements of a facade substructure, in particular for use in ventilated curtain walls.

From the prior art it is known to provide curtain walls with a facade substructure, which is preferably supported on a wall or building wall and at the same time carries the facade panels and these spaced from the building wall.

Usually has a facade substructure wall brackets that are anchored in the building wall, vertical support profiles, horizontal support profiles and holding elements. At the retaining elements, the facade panels are finally attached, which form the outer end of the facade. The facade panels are bolted to the retaining elements or non-positively connected in any other suitable manner. Alternatively, the facade panels can also be fixed directly to the horizontal support profiles, so that no intermediate holding elements are needed.

A generic ventilated facade system is from the document DE 20 2010 004 194 U1 known. To arrange facade elements spaced from a building wall or an insulating layer, in this case a horizontally extending support rail is provided on which holding means are arranged for holding the facade elements. In particular, the holding means are composed of a pressure element and a wraparound element, so that the front side of a facade element can be pressed against the inside of the wraparound element.

Furthermore, in the document DE 296 15 166 U1 describes a facade substructure, which has to be fastened to a wall wall bracket and connectable with a support profile support profile holder. The peculiarity here is that the wall holder and the support profile holder is each pivotally connected to a pivot arm, which is fixed to change the distance of the support profile of the wall in different pivoting positions. On the support profile also facade panels are fastened.

The publication DE 198 52 298 A1 proposes a facade construction whose facade elements are fastened by means of fastening elements arranged on the building wall rails. The fasteners are divided into a support member, a holding part and a fixing part and also have plate holder. Furthermore, the Fasadenkonstruktion is characterized by a provided between rail and fastener gearing.

A fastening device for plate-shaped facade elements in the context of a ventilated curtain wall is off DE 200 03 056 U1 known. The solution disclosed in this case provides a rail fastened to a building wall with a front-side groove, in which a fastening element is infinitely displaceable. Both the connection of the fastener to the rail and the connection of the outer and inner part of the fastener is realized here by means of screw. For attachment of a facade element, the fastening element has corresponding contact surface and contact surfaces.

It is the object of the invention, while avoiding the disadvantages of the prior art to provide a facade construction unit, which allows improved fixation of an agraffe on a horizontal profile carrier and which is at the same time easy to assemble and inexpensive to produce.

The object is solved by the features listed in claim 1. Preferred developments emerge from the subclaims.

A facade construction unit according to the invention has a horizontal profile carrier and a clasp unit.

The horizontal profile carrier can be attached to a substructure. The substructure is preferably made of wall brackets, which are anchored in a building wall, and attached to the wall brackets vertical profile beams. The horizontal profile beams are positively or positively connected to the vertical profile carriers in such a structure of the substructure.

In addition, the horizontal profile carrier on a receiving contour, so that the Agraffeneinheit can be suspended in the horizontal profile carrier. The exterior finish of a façade is ultimately formed by a façade panel, which can be fastened to the agraffen unit.

The clasp unit comprises a base element and a spring element, wherein the base element has a suspension contour whose geometry corresponds to that of the receiving contour. Thus, the receiving contour and the suspension contour in their interaction in the final assembly position provide a positive connection in such a way that in the vertical direction downwards and in both transverse to the longitudinal axis of the horizontal Profilträgers stationary directions is a position fixing the Agraffeneinheit. In the vertical upward direction, the clasp unit is determined by the weight force.

The Montageendlage describes the present state of assembly after the clasp unit has been hooked into the horizontal profile carrier. The hanging is done by moving the Agraffeneinheit in the vertical direction down until the receiving contour and the suspension contour are in the horizontal sections in touching contact and there are burdened by the weight. At the Agraffeneinheit a facade panel is attached, which is in the Montageendlage the clasp unit at the same time in its intended spacing to a wall and vertical position.

The spring element is arranged on the horizontal profile carrier side facing the base element. It has a base portion, a first and a second bending portion and a first and a second end portion. The spring element is mounted on the base portion on the base member at an attachment point. The bending portions are respectively between the base portion and one of the end portions. The spring element also has the feature that the base portion, the bending portions and the end portions are arranged horizontally. The longitudinal axis of the spring element thus extends in parallel to the longitudinal axis of the horizontal profile carrier.

In the final assembly position, the two end portions are at a first and second pressure contact point in a resilient contact with the horizontal profile carrier. Consequently, the clamping force of the spring element acts on the horizontal profile carrier, so that a non-positive connection in the horizontal direction is provided parallel to the longitudinal axis of the horizontal profile carrier by the resilient contact. The frictional connection is primarily in front of the two pressure contact points and in addition to the vertical surface sections of receiving contour and suspension contour, which are pressed against each other by the spring force. Due to the formation of this frictional connection, the basic element is set in its horizontal positional relationship parallel to the longitudinal axis of the horizontal profile carrier. In order for a facade panel fastenable to the clasp element is sufficiently secured against horizontal displacement in its plane plane.

The facade construction unit according to the invention has in particular the following advantages.

It is advantageous that the clasp unit is reliably fixed in its position. This is based on the one hand on the positive connection, which is achieved due to the corresponding geometries of the receiving and the Einhängekontur, and on the other on the frictional connection, which is provided by the contact of the end portions of the spring element at the pressure contact points to the horizontal profile carrier.

Advantageously, the facade panels can be mounted under workshop conditions on the Agraffeneinheit, or preferably to several Agraffeneinheiten. The preassembled assembly of Fassadenpaneel and Agraffeneinheiten can then be mounted in the horizontal profile carrier.

Even after the onset of the preassembled assembly of façade panel and clasps this is fixed in its position and secured by the frictional connection by means of the spring element against horizontal displacements. The advantage here is that it requires no additional measures or assembly steps for securing against horizontal displacement. This is particularly advantageous because the access to the horizontal profile carrier is blocked by the facade panel after hanging the pre-assembled assembly of facade panel and Agraffeneinheiten. According to the prior art, additional stop elements had to be mounted against horizontal displacement.

Furthermore, there is an advantage that the Agraffeneinheit can be hung at any point along the longitudinal axis of the horizontal beam profile. Consequently, there is the advantage of a much better horizontal alignability compared to the facade structures known from the prior art. In particular, the orientation can be infinitely, without tools and both directly during the assembly of a preassembled assembly of facade panel and Agraffeneinheiten and subsequently done. The frictional connection can be adjusted by a suitable dimensioning and design of the spring element so that it can be overcome manually, with the frictional then automatically adjusts to gewüschter horizontal postion again.

Another advantage is that it requires no additional space next to the facade panel for the installation of a preassembled assembly of facade panel and Agraffeneinheiten. Only in the vertical upward direction, a range of motion must be present, by the required way of hooking the Agraffe in the horizontal beam until the entry of the intervention of receiving contour and suspension contour is determined.

For example, façade panels of different sizes can also be fastened to a substructure with this solution without problems because the individual clasp units can be variably spaced from one another and can be suspended from the horizontal profile carrier at the desired location.

Another advantage is that without additional means at the same time a play-free engagement of Agraffeneinheit and horizontal profile element is made, so that the facade construction does not rattle.

Advantageously, in a preassembled assembly of facade panel and Agraffeneinheiten only one Agraffen unit according to the invention, ie be formed with spring element, while one or more further Agraffeneinheiten have no spring element. In this way, an undisturbed thermal expansion is made possible in particular in facade panels with large horizontal hiding by the agraffen units can slide freely horizontally without spring element.

In an advantageous development, the end sections of the spring element are formed sharp-edged at the pressure contact points. As sharp edges are to be understood all training, which increase the friction between the end portions of the spring element and the horizontal profile element due to their geometry. These include in particular serrated formations, burrs and the like. The increase of the frictional connection is particularly effective when the end portions are formed of a hard material such as steel and the profile element consists of a comparatively soft material such as aluminum. Then, a slight notch in the aluminum can be achieved by the end portions, whereby a greater force is required for the horizontal displacement.

In an advantageous development, a first connecting line between the attachment point and the first pressure contact point to the longitudinal axis of the horizontal profile carrier an angle α of 20 degrees to 85 degrees, and a second connecting line between the attachment point and the second pressure contact point to the longitudinal axis of the horizontal profile carrier an angle β from 20 degrees to 85 degrees.

The particular advantage of this geometry of the spring element with respect to the horizontal profile element is that each one leg of the spring element in a horizontal displacement along the longitudinal axis of the horizontal profile element as a result of the horizontal force attack in addition to the spring force about the transverse to the longitudinal axis force vector F is pressed _transversely becomes. In a horizontal displacement of the longitudinal axis of the horizontal profile element in the reverse direction of the other leg of the spring element is additionally pressed. The larger the angle α or β, the larger is the force vector transverse to the longitudinal axis. Due to the additional pressure the adhesion is increased considerably.

As a particular advantage, an extremely reliable horizontal position determination can be achieved. In addition, the size of the horizontal power transmission can be adjusted as desired by simple means already by changing the geometry of the spring element.

In particular 2 shows by means of a partially sectioned side view of the facade substructure unit is in the suspended state, a positive connection of the clasp unit 2 with the horizontal profile carrier 1 achieved. Consequently, a movement of the clasp unit becomes 2 in the vertical direction and in transverse to the longitudinal axis of the horizontal profile carrier 1 Steady direction prevented. For this purpose, the horizontal profile carrier 1 a recording contour 3 on, which with the attachment contour 4 of the primitive 5 corresponds.

In particular in 2a are the recording contour 3 as well as the suspension contour 4 can be seen, wherein the facade substructure according to the invention before reaching the final assembly position and thus before hanging the clasp unit 2 in the horizontal profile carrier 1 is shown. Both the recording contour 3 as well as the suspension contour 4 are composed of a plurality of surfaces, wherein at each of the surfaces provided with a reference numeral in the suspended state, a positive connection is provided.

The longitudinal axis of the spring element 6 runs parallel to the longitudinal axis of the horizontal profile carrier 1 so that both the base section 7 as well as the bending and end sections 8th and 9 are arranged horizontally.

The frictional connection of the spring element 6 and the horizontal profile carrier 1 is in this case formed by the end sections 8th of the spring element 6 each in resilient contact with the horizontal profile beam 1 stand and consequently the clamping force of the spring element 6 acts against it.

To reinforce the frictional connection consists of the spring element 6 in the present example made of steel, while the horizontal profile beam 1 made of aluminum. Due to the corresponding higher hardness of the spring element 6 this can be in the material of the horizontal profile carrier 1 intervene and get caught there, leaving the hinged clasp unit 5 in their position thus additionally hedged.
