Description

FIELD OF THE INVENTION

The present invention relates to a building facade comprising a load-bearing outer building wall, an outer facade running at a distance therefrom and constructed by a plurality of facade panels and an anchoring system for fastening the facade panels to the outer building wall.

STATE OF THE ART

The building exterior wall is typically a part of the building that is manufactured on site, for example. an external building wall made using in-situ concrete or ready-mixed concrete. Alternatively, it can also be a part of a building that is composed of prefabricated wall components. These can also be made of concrete (prefabricated concrete parts), but in principle they can also be made of another material. A brick wall structure is also conceivable.

It is often the case that such building exterior walls are easy to manufacture, stable and very load-bearing, but are usually visually unappealing and even dreary.

However, external facades represent the business card of a building. Accordingly, both architects and builders strive to make external facades visually appealing. In addition, external facades also fulfill various static and building physics tasks, such as thermal insulation and shading. In addition, external facades are often used to produce electricity using solar panels.

In order to be able to fulfill all of these tasks, it is common practice to add an external facade to the load-bearing external wall of the building (often also referred to as a ventilated facade), which consists of a plurality of Facade panels are constructed that can be individually designed (shape, surface, materials) and may also fulfill technical purposes (cooling, e.g. green facades with irrigation systems, etc.).

Since the external facade has to be assembled on site, it is important that the external facade can be attached to the outside wall of the building as easily as possible. In addition, there should also be the greatest possible flexibility when it comes to the arrangement and alignment of the facade panels with one another.

For example, it may be desired that the arrangement of the facade panels should form a large, uniformly flat surface as an outer facade, but in other cases it may be necessary for certain facade panels to be arranged at a certain angle to one another or in relation to the load-bearing outer wall of the building should be.

In the majority of applications, however, it is important that the outer facade forms a flat, vertical surface.

The use of concrete facade panels has proven to be particularly advantageous in practice. These offer numerous design options, can be produced economically in high quality, are robust and have very good mechanical/static properties for most purposes.

However, the high weight of concrete facade panels poses a challenge during assembly, which also requires each panel to be reliably anchored to the outside wall of the building.

In addition, the design of a uniformly vertical external facade requires an exact alignment of the facade panels with each other, otherwise the external facade will appear uneven.

OBJECT OF THE INVENTION

It is therefore one of the objects of the invention to propose a building facade in which it can be ensured that the facade panels forming the outer facade form a uniformly flat surface.

It is a further object of the invention to ensure that the distances between the individual facade panels of the outer facade are always the same size.

Furthermore, the building facade according to the invention should be as simple as possible to assemble, in particular enable quick and safe assembly on the construction site and penetrate any existing insulation level in as few places as possible.

A building facade according to the invention should also have the highest possible degree of prefabrication.

Ultimately, the building facade according to the invention should also enable an angular arrangement of the facade panels in certain applications, either in relation to each other or in relation to the load-bearing outer building wall.

PRESENTATION OF THE INVENTION

This task is achieved in a building facade comprising a load-bearing outer building wall, an outer facade running at a distance therefrom and constructed by a number of facade panels, and an anchoring system for attaching at least one of the facade panels to the building outer wall in that the anchoring system has at least a first and a second support component comprises, wherein the first support component is connected on the one hand to a facade panel and on the other hand to the second support component and the second support component is also connected to the outer wall of the building, the connection between the first and second support components being a relative one Angular alignment and fixation of the two support components to each other is possible.

The support components are preferably stainless steel components, possibly components made of alloy steel.

In a preferred embodiment of the invention it is provided that the connection between the first and second support component is a screw connection. This means that both the angular alignment and the fixation of the two support components to one another can be carried out quickly and safely on site, on the construction site.

It can further be provided that the first support component comprises an anchoring section, via which the first support component is connected to the at least one facade panel and the second support component comprises an anchoring section, via which the second support component is connected to the outer wall of the building. The two support components can therefore be securely connected to the at least one facade panel or the load-bearing outer wall of the building via the anchoring sections. The anchoring sections can be tailored to specific conditions in terms of shape and fastening means and, as will be shown, can also fulfill additional tasks.

According to the invention, it can further be provided that the first support component comprises a connecting section projecting from its anchoring section in the direction of the outer wall of the building and the second support component comprises a connecting section projecting from its anchoring section in the direction of the outer facade and the two connecting sections each have an overlap area within which the connection of the two support components.

According to a further preferred embodiment, at least one connecting element can be provided in the overlap area of the connecting section of the first support component and/or the connecting section of the second support component, in particular at least one opening can be provided, via which the two connecting sections are connected to one another, preferably screwed, whereby the openings can have different distances from the outer facade. The connecting element is understood to be prefabricated elements that are part of the two connecting sections. These can either enable a connection on their own or, as in the case of openings, using another element such as a screw.

The different distances between the connecting elements enable the anchoring system to be adjusted in such a way that the distance between a facade panel and the load-bearing outer building wall can be adjusted within limits specified by the distances.

In a preferred embodiment of the invention, the support components are steel sheets, in particular folded steel sheets, with the anchoring sections and connecting sections each forming a leg. The anchoring section and connecting section of each support component are therefore preferably plate-shaped, ie. their thickness is small compared to their length and width.

The support components are therefore preferably arranged on the building facade in such a way that, in a viewing direction parallel to the outer facade and normal to a contact plane of the building, the anchoring section and the connecting section of each support component run at an angle, preferably at right angles, to one another, so that the moment of resistance for the given load case the anchoring and connecting sections can be utilized accordingly.

Specifically, in this case an anchoring section runs essentially parallel to a facade panel or parallel to the load-bearing outer wall of the building. In this case, a connecting section runs essentially normal to the facade panel or building exterior wall. The preferably provided connection by means of screwing takes place in a direction also parallel to a facade panel or building exterior wall and parallel to the contact plane of the building.

As a rule, an external facade is constructed using a large number of facade panels, with each facade panel being attached to the outer wall of the building using the anchoring system described. In order to be able to save weight of the anchoring system, it can further be provided that, viewed in a viewing direction parallel to the outer facade and essentially parallel to the contact plane of the building, at least one connecting section, preferably both connecting sections of the anchoring system, are triangular and the overlap area of each connecting section is formed by a corner section. This ensures that the connecting sections only have the size that they actually need to fulfill their technical purpose and unnecessary weight is saved.

In order to facilitate the alignment of the facade panels to one another, in a further embodiment of the invention at least one alignment lug can be provided, which projects beyond a boundary edge of the inner surface of a facade panel and engages in a receptacle that is arranged on an adjacent facade panel.

According to the invention, one alignment lug per facade panel or several alignment lugs per facade panel can be provided, which protrude beyond different boundary edges of a facade panel and therefore enable flush alignment with one or more adjacent facade panels.

According to a particularly preferred embodiment of the invention, it can be provided that the at least one alignment lug is formed by a respective section of the anchoring section of the first support component. In other words, the dimensioning or attachment of an anchoring section of the first support component to a facade panel can be carried out in such a way that at least part of the anchoring section projects beyond a boundary edge of a facade panel. In this way, the alignment nose can engage in a receptacle the neighboring facade panel and thus an exact alignment is made possible.

The receptacle preferably tapers in the engagement direction, so that on the one hand the insertion of the alignment lug during assembly is made easier, but on the other hand the alignment lug also experiences a certain fixation in the receptacle if the taper is dimensioned accordingly.

As a particularly easy-to-implement embodiment of a receptacle, it can be provided that it is formed by two spaced-apart strips, preferably sheet metal strips.

Preferably, the receptacle is arranged on the inner surface of a facade panel and the width of a receptacle extends from the inner surface in the direction of the building's outer wall, the width being adjustable by selecting a spacer element in which the strips are screwed to a facade panel with the spacer element in between.

While in principle a wide variety of facade panels can be used to form the outer facade, according to a further preferred embodiment of the invention, an outer facade made of a composite material is provided, comprising concrete and a lattice-shaped reinforcement made of carbon fibers, also called carbon concrete.

This or the reinforcement has a significantly higher tensile strength (up to 7 times) compared to conventional reinforced concrete and is not rustproof. This circumstance means that components can be made thinner and resources can be saved. Compared to conventional concrete facade panels, the component thickness can be reduced by more than 50%. In addition, a reduction in component thickness also means a lower weight for each facade panel.

This circumstance, in combination with the building facade according to the invention, means that in particular the angular alignment and fixation of the first and second support components to one another is not impaired or made impossible by unnecessarily heavy facade panels. It is particularly important to take into account that the assembly of the facade panels takes place on the construction site and therefore under certain circumstances under adverse conditions, but also at great heights.

The advantages of a building facade according to the invention are therefore further enhanced by the use of facade panels made of carbon concrete.

In order to enable the facade panels to be fastened quickly and securely to the anchoring system, it is advantageous if the facade panels are delivered to the construction site with appropriately installed connecting means via which the attachment can take place.

According to the invention, it is therefore provided that at least one facade panel is provided with a concrete-enclosed, preferably cast in concrete, grid-shaped reinforcement (e.g. steel, carbon or glass fiber reinforcement), with at least one connecting means attached to the reinforcement being provided, which has an overhang protrudes from the concrete and the at least one connecting means is fastened to the reinforcement via plate-shaped clamping elements, a first clamping element being arranged on one side of the reinforcement and a second clamping element being arranged on a side of the reinforcement opposite the first side, and wherein the at least one connecting means runs in a direction transverse, preferably normal, to the plane of the reinforcement, the two clamping elements preferably having a shape which is larger than a mesh opening of the grid-shaped reinforcement or, alternatively, only cover part of a mesh opening.

The appropriately prefabricated facade panels can therefore be immediately connected to the anchoring system without any further processing.

In a preferred embodiment of the invention, the clamping elements are clamped against the reinforcement using a screw/nut combination. The screw or screws used also act as connecting elements for the anchoring system. The lengths of the screws are chosen so that they protrude from the poured concrete with an overhang.

In principle, however, other embodiments are also conceivable in order to clamp the two clamping elements against the reinforcement or it can also be provided for the screws functioning as connecting elements to be clamped directly to the reinforcement without clamping elements using only a screw nut, which, however, means that the loads that can be introduced without danger are lower .

Fig.1 shows a sectional view of a part of a building facade 1 according to the invention along section line BB Fig.2 . An outer facade 3 is attached to a load-bearing outer building wall 2, which can be made of in-situ concrete, for example. The outer facade 3 comprises a number of facade panels 3a, 3b,... 3n where in Fig.1 For the sake of simplicity, only two facade panels 3a, 3b are shown, while in Fig.5 the same building facade 1 is shown with three facade panels 3a, 3b, 3c.

In the exemplary embodiment shown, the facade panels 3a, 3b, 3c are facade panels made of carbon concrete. The reinforcement made of carbon fibers is provided with the reference number 18. In principle, the use of other facade panels is also conceivable, for example facade panels made of concrete with conventional steel reinforcement or reinforcement made of glass fibers.

Each facade panel 3a, 3b,... 3n is connected to the load-bearing outer building wall 2 via an anchoring system 4. The anchoring system 4 comprises a first support component 5 and a second support component 6, the first support component 5 being connected to a facade panel 3a and the second support component 6 being connected to the load-bearing outer facade 2.

For reasons of clarity, in the Fig.1 , 2 , 3 and 4 only a single anchoring system 4 is shown, which anchors a facade panel, in the present case the facade panel 3a, to the load-bearing outer wall 2.

As already mentioned above, however, a building facade according to the invention comprises a number of such facade panels, it being provided according to the invention that each facade panel of this number of facade panels 3a, 3b,.....3n is connected to the load-bearing outer wall 2 via an anchoring system 4, like this for example in Fig.5 is shown using the facade panels 3a, 3b.

The support components 5,6 are angular in the present exemplary embodiment, as shown in Fig.2 , which makes a cut according to line AA Fig.1 represents, as well as in the Fig.6 and 7 is visible. For example, a folded steel sheet can be used as the support component 5, 6, with one leg forming an anchoring section 5a, 6a and each leg forming a connecting section 5b, 6b.

The anchoring sections 5a, 6a serve to anchor the illustrated support components 5,6 to the facade panel 3a or to the load-bearing outer building wall 2, the connecting sections 5b, 6b serve to connect the two support components 5,6.

The anchoring section 6a, which lies essentially flat against the load-bearing outer building wall 2, can be anchored in the load-bearing outer building wall 2, for example, using concrete dowels 24, ie. The support component 6 is screwed to the load-bearing outer wall 2 of the building, if necessary with the interposition of one or more spacer elements 26.

The connecting sections 5b, 6b run essentially at right angles to the anchoring sections 5a, 6a so that these components overlap in an overlap area 8 in the space between the outer facade 3 and the load-bearing outer building wall 2. In principle, it is also conceivable that the connecting sections 5a, 6a are not at right angles to the Anchoring sections 5a, 5b run. In this case, however, it is necessary for the function that the connecting sections protrude at the same angle from the anchoring sections 5a, 5b, so that a connectable overlap area 8 can be formed.

In the exemplary embodiments shown here, the connecting sections 5b, 6b are also essentially triangular in a viewing direction parallel to the outer facade and essentially parallel to the contact plane of the building, the overlap area 8 of each connecting section 5b, 6b being formed by a corner section.

In the overlap area 8, at least one connecting element 16a, 16b, 16c is arranged both in the connecting section 5b of the first support component 5 and in the connecting section 6b of the second support component 6, via which the two connecting sections 5b, 6b can be connected to one another.

In the present exemplary embodiments, the connecting elements 16a, 16b, 16c are designed as openings through which the two connecting sections 5b, 6b can be screwed together. In the event that several connecting elements 16a, 16b, 16c are provided, these can be arranged spaced apart from one another in a direction normal or parallel to the facade panel 3. In this way, the length of the overlap area 8 can be adjusted and thus the distance between the outer facade 3 and the load-bearing outer building wall 2. The resulting variable space between the outer facade 3 and the load-bearing outer building wall 2 offers space for insulating material 25, which is at this point can be provided.

Alternatively, the at least one connecting element 16a, 16b, 16c can also be designed as an elongated hole.

Fig.4 shows an axonometric view of the anchoring system 4 with a view of the facade panels 3a, 3b from behind, i.e. the space between the load-bearing outer building wall 2 and facade panels 3a, 3b. For the sake of clarity, both the load-bearing outer building wall 2 and the alternative insulation material 25 are not shown. The Ends of the concrete dowels 24, which would normally be anchored in the load-bearing outer building wall 2, therefore protrude Fig.4 into the void.

Very good is in Fig.4 the overlap area 8 can be seen, as well as the screw connection 7, with which the connecting section 5b of the first support component 5 is connected to the connecting section 6b of the second support component 6.

For better alignment of adjacent facade panels, as in Fig.8 shown, an alignment nose 11 may be provided, which projects beyond at least one boundary edge 10 of an inner surface 9 of a facade panel, here specifically facade panel 3a.

The alignment nose 11 engages in a receptacle 12, which is arranged on an adjacent facade panel, here specifically facade panel 3b.

The receptacle 12 can be tapered in the engagement direction to facilitate insertion and to create a type of press fit to prevent noise-emitting vibrations. The width of the receptacle 12 extends from the facade panel 3b in the direction of the load-bearing outer wall of the building.

The alignment nose 11 can either be formed by a section of the anchoring section 5a of the support component 5, as shown in FIG Fig.8 and 9 is shown or can be arranged as a separate component on the inner surface 9 of a facade panel 3a, as shown in FIG Fig.10 , 11 is shown.

In both cases, the receptacle 12 can be formed by two spaced-apart sheet metal strips 13a, 13b, which are attached to the facade panel 3b, in particular screwed to it.

Regardless of whether the alignment nose 11 is formed by a section of the anchoring section 5a or by a separate component, it can be provided that the strip 13a is arranged recessed in the adjacent facade panel 3b. For this purpose, the facade panel 3b has a corresponding recess 27 Mistake. The alignment nose 11 can thereby run flush with the inner surface 9 of the facade panel 3a.

Fig. 12 to 15 show connection options for the anchoring section 5a to a facade panel 3a.

As already stated above, in the exemplary embodiments shown, the facade panels are carbon concrete facade panels 3a, 3b, 3c, but in any case facade panels that have reinforcement 18.

Regardless of the type of reinforcement 18, connecting means 17 are fixed to it, which protrude beyond the concrete 19 with an overhang 20 and are preferably cast with it. The connection means 17 serve to establish the connection of the facade panels to the anchoring system 4, in particular the connection to the support component 5.

The attachment means 17 is fixed to the reinforcement 18 via clamping elements 21a, 21b, which can be more or less plate-shaped, as shown in FIG Fig. 12 to 15 is shown. The two clamping elements 21a, 21b are arranged on both sides of the reinforcement 18 and span in the in Fig.14 illustrated embodiment a mesh opening 23 of the reinforcement 18. In the in Fig.13 In the embodiment shown, the clamping elements 21a, 21b are arranged so that no mesh opening 23 is completely spanned; rather, the clamping takes place asymmetrically via a node 28 of the reinforcement 18.

While in the embodiments in the Fig. 12 to 14 the two clamping elements 21a, 21b are the same size, comes in the embodiment according to Fig.16 a longer clamping element 21a is used, which spans several mesh openings 23. On the opposite side of the reinforcement 18, however, several small clamping elements 21b are used.

The clamping of the clamping elements 21a, 21b takes place in the embodiment as in Fig. 12 to 15 shown via one or more screws 14, which acts as connecting elements 17.

For this purpose, the clamping element(s) 21a has one or more openings 22a and the clamping element 21b has one or more openings 22b through which the screw shaft of the screw 14 is guided.

The clamping elements 21a, 21b are clamped to the reinforcement 18 by means of a screw nut 29.

Alternatively, the screws 14, which function as connecting elements 17, can also be clamped directly to the reinforcement 18 without clamping elements using only a screw nut 29, as shown in Fig.16 , 17 is shown. In this case, the fixation takes place mainly via the concrete 19, so that the loads that can be introduced safely are lower.
