CONSTRUCTION ELEMENT AND METHOD FOR CREATING A CONSTRUCTION ELEMENT

description

The present invention relates to a novel construction element, which is particularly suitable as an outer wall for forming a building envelope, as a wall covering, as a partition, as a facade element but also as a roofing.

The invention further relates to a method for producing such a construction element.

The starting point of the present invention is a generally known from the prior art post-and-beam facade system, which has now almost completely displaced the classic solid perforated facades, especially in the field of building, as post-and-beam facade systems allow significantly lighter facade constructions and especially better Exposure options and a significantly larger visual reference to the outside. A mullion and transom façade is a façade system made up of load-bearing profiles. With the mullion and transom construction, relatively large openings but also entire façade surfaces can be produced. The construction is based on the combination of vertical post profiles (main profiles) and horizontal transom profiles, which together form a skeletal supporting structure. The load transfer takes place via the vertical posts. In a mullion-and-transom façade system, the infills may be either transparent or opaque. ken Material ien exist. Between the load-bearing facade scaffolding and the facade fields usually elastic sealing profiles are used.

Usually, the post-and-beam facade system on the construction site on site from individual parts artisanal and glazed there, or provided with the infills.

The present invention is based on the problem that, although the known post-and-beam facades are lightweight facade constructions compared to solid perforated facades, which also offer a significantly better exposure possibility, however, the structure and assembly of the skeletal support structure in particular, but also the onset of infills, especially the subsequent vitrification associated with relatively many steps on site and thus comparably time consuming. In this respect, the present invention has for its object to provide a novel facade construction, which offers better exposure options and a much larger visual reference to the outside compared to solid perforated facades similar post-latch facades, however, significantly reduces the amount of manual work during installation shall be.

A further object of the invention is to provide a structural element for cladding facades or roofs or for forming exterior walls or partitions of a building, which on the one hand has a high thermal resistance and at the same time draws maximum benefit from the available solar energy ,

Finally, it is an object of the present invention to provide a method by which such a structural element can be produced in an easily realizable and automatic manner, in particular by reducing the number of components required to form the structural element.

According to the invention, the above objects are achieved by the subject matters of the independent claims. Advantageous developments are specified in the dependent claims. Accordingly, the present invention relates in particular to a construction element, such as a prefabricated wall or an elemental façade, wherein this construction element is designed as a self-supporting and / or as a flat supporting sandwich element, which has an interior as well as double-sided glass cover layers and the interior defining cover layers from a glassy material. Here, the term "cover layer" is understood to mean a surface element made of glass or a vitreous material, in particular a single-pane safety glass pane (ESG) or a laminated safety glass pane (VSG).

The core of the sandwich element is a material with heat-insulating properties which is accommodated in the interior defined or bounded by the two-sided (glassy) cover layers. The structure and operation of the construction element according to the invention differ significantly from the conventional mullion-transom façade, since it is in the present case a sandwich element, d. H. a construction product, which has two mutually frictionally connected glass cover layers and a heat-insulating core. Due to the frictional connection of the two cover layers, the cover layers together with a support structure integrated in the construction element act together under load, so that the construction element is to be regarded as a self-supporting element (surface support). The term "self-supporting element" is generally understood to mean an element which, by virtue of its material and shape, is capable of bearing both its own load and all loads (eg snow, wind, internal air pressure) acting on the element In other words, the supporting structure formed by the vertical posts in conventional mullion-and-transom constructions is integrated within the structural element according to the invention so that it is no longer required for on-site erection The construction element according to the invention in the form of a self-supporting sandwich element, in which the two-sided outer layers of glass or a glass-like material shear-resistant connected to each other via an integrated support structure, it is thus and a special form of solid wall construction, since the construction element prefabricated in panel construction over several storey heights and can be delivered to the site. The attachment of the construction element is preferably made via fixed and sliding bearings. Here can be varied between a standing façade, where the camps are located below, and a hanging facade, with the fixed camps above. Statically cheaper, however, would be continuous beam, which can run over several floors headboards away, since only one repository is to be designed as a fixed bearing, depending on whether the facade is or is hanging. However, a disadvantage of the continuous carrier in the sound transmission from floor to floor over the continuous profiles.

As already indicated, in the solution according to the invention, the frictional and shear-resistant connection between the two cover layers, which are preferably designed as glass panes, is realized with the aid of a support structure integrated in the construction element. This support structure is integrated and formed in the structural element in such a way as to form a supporting structure, that is to say to form a building structure constructed with the aid of at least one supporting profile, which serves for receiving and discharging attacking loads. In this case, the loads of the construction element as well as all other loads introduced into the construction element, such as wind loads, are considered as loads.

In a preferred realization of the solution according to the invention, the support structure integrated in the construction element is joined to the inner surfaces of the two-sided outer layers defining the inner space in a shear-resistant manner, in which case in particular a cohesive connection (gluing) is used. In a particularly easy to implement, yet effective manner, the support structure integrated in the construction element has at least one support profile which is integrated in the construction element and arranged between the cover layers of the construction element, that between the inner surfaces of the two-sided cover layers a predetermined or definable distance is defined. Depending on the desired thermal insulation behavior or other insulating properties is thereby the Distance adjusted between the inner surfaces of the outer layers. In practice, it has been found that a minimum distance of 50 mm is advantageous.

In order to be able to realize as large openings as possible and in particular optimum exposure possibilities and the greatest possible visual reference to the outside, it is provided according to one aspect of the present invention that the two-sided, the interior of the construction element limiting and defining cover layers each as a surface element, in particular monolithic surface element a (single) glass material or a (single) glasar- term material are formed, in which context it has turned out to be particularly advantageous if the two surface elements are designed without material interfaces and seamless. In this way, the design element is not or only insignificantly influenced by weathering in terms of its functionality.

The formation of the cover layers of the construction element as surface elements made of glass or a vitreous material has the further advantage that the surface elements can be selectively and individually made at least partially opaque in a particularly easy to implement manner. This is preferably done by applying a coating to the side surface of the corresponding surface element facing the interior of the construction element. The coating may be, for example, an enamel layer; however, other coatings are also suitable, for example plotter or roller pressure coatings, or even screen-printing coatings. In this context, it is also conceivable that an active or activatable sun protection coating is provided on at least one inner surface of the two surface layers formed as a surface element in order to increase the opacity of the corresponding surface element, if necessary. According to one aspect of the present invention, it is provided that an insulating material is at least partially introduced in the interior defined and bounded by the cover layers of the construction element. For example, rigid polyurethane foam is suitable, which is also referred to as "PU foam" or "polyurethane foam" and has excellent insulating properties. In fire protection requirements, however, it is advantageous if the

Insulating material consists of mineral wool or similar fiber material. Selbstver- Of course, other solutions come into question here, such as loose fibers inserted into the interior, flakes introduced into the interior, in particular injected flakes, insulating material in the form of chips or honeycomb-shaped insulating elements. Also, a material in the form of a bed would be conceivable.

In a particularly preferred embodiment of the construction element according to the invention, provision is made for a window area to be formed inside the construction element which, for example, serves to introduce sunlight into the interior of the building. For this purpose, an arbitrarily formed (round, rectangular, etc.) cavity may be formed in the insulating layer forming the core of the sandwich element, which cavity forms a space free of insulation material. With this embodiment, it is possible to realize on the one hand excellent insulation properties, on the other hand at the same time an entry of sunlight is made possible in the interior of the building. Of course, the construction element according to the invention may have a plurality of individual insulating material-free spaces, which are arranged distributed at regular or irregular intervals. Since air is preferably located within the insulation material-free intermediate space, pressure fluctuations can occur, in particular due to the heating by the sunlight within the transparent partial area. In order to ensure this circumstance, in a preferred development of the solution according to the invention, it is provided that the insulation material-free space has a frame element which is designed to compensate for pressure fluctuations within the transparent portion.

According to a particularly simple construction of the frame element, the latter may have, for the purpose of pressure compensation or for the purpose of compensating pressure fluctuations, a first compensation volume which is in fluid communication with the already mentioned cavity of the insulation material-free intermediate space. Further, for example, is provided as a second compensation volume, which is connected via a fluid-tight membrane with the first compensation volume and having a pressure compensation opening. Thus, an effective pressure equalization can take place without the entire transparent partial rich to connect with the outside air and thus reduce the insulating properties of the structural element.

As an alternative or in addition to this, at least a portion of the insulation material-free intermediate space can have a transparent surface element. This transparent surface element may be, for example, a glass element, which is covered by the insulating layer. By providing a transparent sheet member, the air space (i.e., the air volume) within the transparent portion is reduced, thereby effectively reducing pressure fluctuations.

According to a further realization of the construction element according to the invention it is provided that a Beleuchtungseinrichtu ng and / or display device is integrated in the interior of the construction element, so that corresponding lighting effects or information can be detected from the outside over the at least partially transparently formed first surface element. At the same time, the first surface element, which is at least partially transparent, simultaneously undertakes the cover for the lighting or display device. It is also conceivable in this context, for example, to integrate OLED films within the construction element.

Finally, according to a further aspect of the invention, the construction element is substantially rectangular, wherein on at least one outer edge of the construction element, a tongue and / or groove profiling is provided, which serves to form a connection with an adjacent (adjacent) construction element , Of course, other solutions for connecting adjacent construction elements come into question.

Briefly summarized, it should be noted that the construction element according to the invention is characterized in that it is a statically self-supporting element, in particular a sandwich element, which is suitable for forming a wall and / or roof structure without complex post frame structures or the like is provided because in the structural element already the structure is integrated. Thus, the construction element according to the invention represents a cost-effective and additionally aesthetically very attractive alternative to conventional facade constructions. The invention relates not only to the novel construction element, but also to a method for producing such a construction element, wherein the method is characterized in particular by the fact that a self-supporting element facade can be realized in only a few process steps and with only a few components. Essentially, this merely requires that a support structure is integrated into the intermediate space of two spaced-apart surface elements, which preferably takes place in such a way that this support structure is connected in a shear-resistant manner to the two surface elements. The formation of a shear-resistant connection is preferably carried out by gluing.

In the following, embodiments of the construction element according to the invention are explained in more detail with reference to the accompanying drawings. Show it :

For the sake of clarity, identical or identically acting components are provided with the same reference numerals below.

A first embodiment of the construction element according to the invention for the cladding of facades and roofs is shown in Fig. 1. The construction element has a first outer surface element 11 and a second inner surface element 12. The second inside surface element 12 is arranged parallel to the first surface element 11 and connected via an insulating layer 13 with the second inside surface element 11. Although this is not explicitly shown in FIG. 1, but it is conceivable that between the insulating layer 13 and the respective surface elements 11 and 12, an additional adhesive layer is provided, which connects the surface elements 11, 12 with the insulating layer 13.

According to the invention, at least the first outside surface element is designed to be transparent in order to make better use of solar energy and to produce an improved visual impression.

The insulating layer 13 is preferably formed of rigid polyurethane foam, but may also consist of any other foamed insulating material. An insulating layer 13 made of rigid polyurethane foam has the advantage that it is possible to draw on an adhesive layer between the surface elements 11, 12 and the insulating layer 13. For this purpose, during the production of the construction element, the rigid polyurethane foam can be sprayed into a space between the surface elements 11, 12 in order to completely foam it out. Unlike the first outer surface element 11, the second inner surface element 12 may be formed either transparent or opaque. It is conceivable that the second inside surface element 12 is formed from materials such as glass, metals or plastics. However, it is particularly advantageous if the second inside surface element 12 is designed as a transparent surface element. In particular, these may be, for example, fluid glass, Plexiglas or polycarbonate. By forming the second inside surface region 12 as a transparent surface element, in particular, a transparent subregion can be formed in the construction element, as will be described in more detail below with reference to the illustrations in FIGS. 2 a to 2 d.

FIGS. 2a to 2d show that, according to one embodiment of the invention, the insulating layer 13 can have at least one intermediate space 14 free of insulating material, which extends from the first planar element 11 to the second planar element 12 and is designed to form a transparent partial region. The simplest form of such a damaging material-free Gap 14 is shown in Fig. 2a. According to FIG. 2a is in the transparent portion only to a cavity 17 within the insulating layer 13, which forms the insulating material-free space 14. This cavity 17 can have any shape, for example round or square. The transparent partial region of the construction element 1 formed by the insulating material-free intermediate space 14 in particular assumes the function of a window, ie it serves to feed sunlight into the interior of a building. The insulating material-free intermediate space 14 is preferably introduced directly into the insulating layer 13 during the foaming mentioned above. This can be achieved, for example, by providing a frame element 20 (FIG. 2b) between the surface elements 11, 12 prior to foaming.

As can be seen from FIG. 2b, the insulating material-free intermediate space 14 can have a frame element 20 which is designed to compensate for pressure fluctuations within the insulation material-free gap 14. As shown, the frame element 20 has for this purpose a first compensation volume VI, which is in fluid communication with the cavity 17 of the insulating material-free gap 14. Furthermore, the frame element 20 has a second compensation volume V2 which is fluid-tight

Membrane 22 is separated from the first compensation volume VI. The second compensation volume V2 has a pressure equalization opening 23, which is shown schematically in the illustration, by way of which an overpressure or underpressure within the cavity of the insulation material-free intermediate chamber 14 can be compensated.

In detail, a situation is shown in FIG. 2b, in which an overpressure prevails in the cavity 17, which overflows via a permeable membrane 21 into the first compensation volume VI and thus bears against the fluid-tight membrane 22. As a result of the overpressure in the cavity 17 and the first compensation volume VI, the fluid-tight membrane 22 bends in the direction of the second compensation volume V2, whereby the first Kompensationsvol VI is increased and thus results in a pressure compensation. For a better understanding of the embodiment shown in Fig. 2b is in Fig. 3 is a sectional view from above along the section axis shown in Fig. 2b III-III shown. As can be seen, the insulating material-free gap 14 according to this embodiment is round. Of course, it is also conceivable to form it in various other forms (eg rectangular). The dashed line represents not about a hidden edge, but the permeable membrane 21, via which the first compensation volume VI is in fluid communication with the cavity 17. The first compensation volume VI is in turn separated by the fluid-tight, flexible membrane 22 from the second compensation volume V2. This results in a transparent part of the construction element, which on the one hand can be used as a light passage and at the same time is able to compensate for pressure fluctuations.

According to an alternative embodiment, the pressure fluctuations within the insulation material-free gap 14 can be reduced by a transparent volume element 30 or 40, which is arranged at least in a partial region of the insulation material-free gap 14. Two examples of such transparent volume elements 30, 40 are shown in FIGS. 2c and 2d. With regard to the transparent volume element shown in FIG. 2c, it should be mentioned that this can be designed in particular in one piece. In particular, the integrally formed transparent volume element 30 can thus be enclosed by the insulating layer 13, so that only a small remaining portion of the insulating material-free intermediate space 14 is formed as hollow space filled with air. By reducing the air-filled cavity 17, the pressure variations within the insulator-free space 14 are effectively reduced. The one-piece transparent volume element must by no means - as shown - be rectangular in cross-section; Rather, it can be provided, the volume element with curved surfaces, d. H. as an optical lens, form to optimize the light input.

Alternatively, as shown in FIG. 2d, a multi-part transparent volume element 40 may be provided. It is preferred to form this as insulating glass arrangement. In detail, this insulating glass arrangement has a first transparent surface element 41, which is connected via spacers 43 to a second transparent surface element 42. To this The cavity 17 of the insulating material-free gap 14 is subdivided into three partial areas 17a, 17b, 17c, which in turn makes it possible to compensate for the pressure fluctuations. The transparent surface elements 41, 42 may also be designed as lens optics, which enlarges the aperture of the transparent partial region.

As shown in FIG. 4 schematically indicated, the first and / or the second surface element 11, 12 may be formed as a glass laminate 1 12 '. Of course, this applies to each of the in Figs. 2a to 2d illustrated embodiment of the inventive construction element 1. The formation of the surface elements 11, 12 as glass laminate 1 12 ', can be used to improve the sound insulation of the construction element 1 of the invention. A further improvement of the sound insulation properties can be achieved with a likewise in FIG. 4 shown third surface element 15 can be achieved. As shown, the third surface element 15 may preferably be disposed within the insulating layer 13 and parallel to the first and second surface elements 11, 12. The third surface element 15 is glued in particular to the insulating layer 13. This can be done for example by additional adhesive layers or alternatively by the adhesive properties of the insulating layer 13 itself. Depending on the application, the third surface element 15 may be a plate element with a certain thickness, which is made of glass, metal or plastic.

Of course, the third surface element 15 should be adapted to the insulating material-free spaces 14 shown in FIGS. 2 a to 2 d, as far as these are provided. For this purpose, the third surface element 15 may have corresponding transparent regions or openings, which are arranged in the region of the insulating material-free intermediate space 14.

From Fig. 5 it can be seen that the construction element 1 according to the invention can furthermore have a solar device 16, which is arranged between the first surface element 11 and the insulating layer 13. The solar device 16 may be, for example, a plurality of photovoltaic modules, which are arranged together in the form of a photovoltaic film. This photovoltaic film is in the inventive construction element 1 between see the insulating layer 13 and the first, outer surface element 11 glued. Accordingly, it is of course conceivable that see the first, outside surface element 11 and the solar device 16 and between the solar device 16 and the insulating layer 13 additional adhesive layers (not shown) are located. Since the first outer surface element 11 is designed to be transparent according to the invention, the solar device 16 can readily be integrated integrally into the volume element 1 according to the invention and thereby utilize the solar radiation impinging on the transparent surface element 11 for energy generation.

Preferably, the solar device 16 is formed as a thin-film Voltaikeinrichtung and has at least one layer of conductive and / or semiconductive materials, which is at least partially vapor-deposited on the inner surface of serving as a carrier material and transparent first surface element 11. In the figures 6a to 6c it is shown that the construction element 1 is preferably formed substantially rectangular and at the outer edges of the insulating layer 13 grooves 131 and / or springs 132 for connecting a plurality of construction elements 1 with each other. In detail, it can be seen from FIGS. 6a and 6b that the construction element 1 according to the invention has a respective groove 131 on an outer edge of the insulating layer 13 and a spring 132 on the opposite side. The grooves 131 and springs 132 are formed so that a plurality of structural members 1 (Fig. 6a) can be easily connected to each other. In detail, the springs 132 of a first construction element can be introduced into the grooves 131 of a second construction element, whereby a verschmeidweicher composite is formed.

In order to obtain a bumpless outside (transparent) surface after assembly of the construction elements 1, the first outside surface elements 11 are each arranged such that they project beyond the outer edge of the insulation layer 13 on the groove side. The situation is analogous with the second inside surface element 12. In other words, the surface elements 11, 12 are arranged opposite the insulation layer 13 such that they cover the connection gap 18 which is formed between the insulation layers 13 of the individual construction elements 1. From Fig. 6b shows a connection between a construction element 1 according to the invention and a construction element 100 known from the prior art. Again, the insulating layer 13 is formed with grooves 131 and springs 132, wherein the spring engages in the example shown in a groove 1131 of a conventional construction element 100. Also according to this embodiment, the surface elements 11, 12 are arranged opposite to the insulating layer 13, that they cover the connecting gap 18 between the construction element 1 according to the invention and the conventional construction element 100. Similar to the construction element according to the invention, the construction element 100 known from the prior art also has an insulation layer 113 which is covered by two surface elements 111, 112. As already indicated above, the surface elements 111, 112 are formed as metal sheets and arranged opposite the insulating layer 113 in such a way that the outer edges of the insulating layer 113 are also projected beyond this. Thus, it is not only possible by the construction elements according to the invention to produce a connection of several construction elements 1 according to the invention with each other; Rather, it is also conceivable to connect the construction elements 1 according to the invention with conventional construction elements 100, whereby the design possibilities are set very little.

Another embodiment of the attached to the outer edges of the insulating layer 13 grooves and / or springs can Fig. 6c are removed. According to this embodiment, the insulating layer 13 has two parallel springs 132, which are designed to receive two complementary grooves 1131, running parallel to one another, of a second structural element 100. It follows that the configuration of the grooves and springs of the construction element 1 according to the invention can be made very variable depending on the application. Of course, the springs and grooves 131, 132 are preferably each adapted to existing construction elements.

In Fig. 7, a further embodiment of the construction element 1 according to the invention is shown. In this embodiment, to increase the

Shear stiffness and to improve the adhesion between the Flächenelemen- th 11, 12 and the Dämmmaterialschicht 13 a reinforcement 19 is provided. The reinforcement 19 is preferably a reinforcing material, such as For example, a glass fiber or synthetic fiber fabric, which is at least partially penetrated by the insulating material. Instead of a fabric structure, however, it is also conceivable to use glass fibers or plastic fibers as a reinforcement 19. Alternatively or additionally, the reinforcement 19 may also be formed as a honeycomb structure, in particular paper honeycomb structure, wherein the insulating material of the insulating material layer 13 is at least partially filled in the individual honeycomb of the honeycomb structure KTUR.

In order in particular to increase the adhesion between the surface elements 11, 12 and the Dämmmaterialschicht 13, a reinforcing adhesive layer is preferably also provided, which is formed between the first and / or second surface element 11, 12 and the Dämmmaterialschicht 13, wherein the Armierungskleberschicht on the inner surface is formed of the first and / or second serving as a carrier material surface element 11, 12.

Of course, other embodiments for the reinforcement 19 come into question.

In Fig. 8 shows a schematic cross-sectional view of a possibility for connecting two construction elements 1. In the in Fig. 8, the construction elements 1 are provided with corresponding groove-shaped profile ends 45, in which a locking element 46, which preferably also has a composite structure, is inserted. This type of connection allows a particularly easy replacement of one of the two structural elements 1. On the structural element or latch element 46, supports 47 can be attached in order to fasten the entire structural element structure to a post of, for example, a mullion-transom construction. The support member 47 may also be used to attach, for example, sun protection devices. An intermediate space between the groove-shaped regions and the carrier element is preferably sealed by means of seals 48.

FIGS. 9a to 9c show plan views of different embodiments of a structural element 1 designed as a facade element according to the present invention. Each structural element 1 has a length L which is sufficient for the structural element 1 to have at least one, Preferably, two and more preferably three floors of, for example, an office building can cover. In the illustrated embodiment, the length L is a total of 13 meters. Of course, other lengths are conceivable here as well.

The in Figs. 9a to 9c shown different embodiments of the structural element 1 designed as a facade element differ essentially by their respective width B. While the facade element according to FIG. 9a, for example, has a width B of 1375 mm, in the facade element according to FIG. 9b has a width B of 1605 mm and a width B of 2400 mm is selected for the facade element as shown in FIG. 9c.

All embodiments have in common that they have a total of three insulating material-free spaces 14 which each extend from the first transparent surface element 11 to the second transparent surface element 12 of the construction element 1 and form a transparent portion. In contrast to the embodiment shown in FIG. 3, in the embodiments according to FIGS. 9a to 9c, the insulating material-free spaces 14 seen in a plan view rectangular. In detail and as in Figs. 9a to 9c, it is conceivable, for example, that the insulating material-free intermediate spaces 14 have a length L 'of 400 mm or 300 mm. The dimensions of the insulating material-free spaces 14 are selected depending on the application of the facade element accordingly.

Fig. 10 shows a cross-sectional view through two construction elements 1 connected according to the invention and designed as facade elements. As shown, the design elements 1 designed as a facade element are formed at their edge region as groove-shaped profile ends 45. For this purpose, there is provided that the insulating material not with the first and second surface element 11, 12 concludes, but forms a groove-shaped recess in which a locking element 46 can be accommodated. On the inside of the surface elements 11, 12 can be applied by means of, for example, a screen printing process, a coating 50, in particular a UV protection. Between the insulating material-free gap 14 and the insulating layer 13, an assembly element 51 is arranged, which preferably also from a foamed material is formed. The surface of the assembly element 51 pointing in the direction of the insulating material-free gap 14 is preferably provided with an optical layer 52. In the assembly element 51, a pressure equalization tube 53 can be accommodated in order to allow a pressure equalization between the cavity subareas 17a and 17b. The cavity portions 17 a, 17 b are formed in the insulating material-free gap 14 by providing a third surface element 15. The third surface element 15 is held by the assembly element 51, namely plane-parallel to the first and second surface element 11, 12th

Hereinafter, with reference to the illustrations in FIGS. 11 to 16, further exemplary embodiments of the constructional element 1 according to the invention will be described. In detail, Fig. 11 shows a plan view of a structural element 1 according to the ninth exemplary embodiment. The structural element 1 of this exemplary embodiment is designed in the form of a self-supporting sandwich element and has double-sided glass cover layers which are spaced apart from one another and thus define an interior space of the structural element 1 formed between the glass cover layers. As with the other embodiments of the construction element 1 according to the invention disclosed herein, the glass cover layers are designed as surface elements 11, 12, which are in particular monolithic surface elements made of a glass material.
