Description

Field of the invention

The present invention relates to a connector for a building envelope according to the preamble of claim 1. Furthermore, the invention relates to an outer envelope and a connection piece for a connector.

State of the art

Connectors for a building envelope are known, which can accommodate at least two mutually oriented and / or adjacent load-bearing elements, in particular beams, profiles, posts or bars, at one end of a load-bearing element, and thus can connect the various load-bearing elements indirectly.

Such connectors can be, for example, a profile joint for connecting two load-bearing elements, or else a node, in particular a facade node, for connecting three or more load-bearing elements.

A connector of the type mentioned with a total of three connections for load-bearing elements (support profiles) is made DE 10 2014 108 562 A1 known where the connector is referred to as a "node element".

Window facades are usually designed and erected either as element facades or as mullion and transom facades. In the case of element facades, self-contained prefabricated window elements, which consist of window profiles and glass, are mounted on the shell. In the case of mullion and transom facades, profiles are first installed as mullions and transoms hanging in between on the construction site and the glass panes are subsequently inserted on the construction site.

In both cases, individual extrusion profiles, usually made of aluminum, developed in-house or from system components, are cut and joined. Junctions at which two profiles meet are called profile joints. Junctions at which three or more profiles meet are called facade junctions. Profile joints are usually formed using simple insert pieces that are attached to a profile. The profile to be connected is slipped over the insert and fixed with fasteners (e.g. screws).

In the case of nodes, there are pre-fabricated insert nodes for simple connections of system components, such as a flat 4-way node at 90-degree angles, over which the profiles are pushed. In the case of more complex nodes, profiles must be recorded in different planes and angles. For this purpose, the node inserts are currently being welded from individual parts. The profiles to be slipped over must be processed correspondingly in a complex manner.

A precisely fitting, tightly fitting joint of the profiles in the node is generally only possible with circular profile geometries. The profiles are usually made of aluminum or steel.

Furthermore, the assembly of a complex structure as a "plug-in connection with stroke" is not possible, as there is often no space (stroke) available to shift the profiles in the longitudinal direction.

Problem and task

The conventional manufacture of connectors for the building envelope is technically complex and difficult to customize.

The creation of individual, additively manufactured nodes in the materials customary for large-format window profiles, such as aluminum and steel, is a very energy-consuming and currently time-consuming manufacturing process. The dimensions customary in construction exceed the customary installation spaces of SLM printers available on the market. The material behavior of additively manufactured components differs in its properties from extruded profiles, namely due to the manufacturing process. There are currently no more precise scientific findings or standards.

It is possible to use additive manufacturing to produce dimensionally highly accurate components with complex shapes. Additive manufacturing with plastics has been on the market the longest and is also the most technically advanced. Additive manufacturing with metals is possible, but currently not very reliable. The risk of faulty production is comparatively high, which in combination with the currently long production time leads to major problems.

The plastics commonly used in additive manufacturing are usually flammable. However, the use of flammable or even flame-retardant building materials for load-bearing components is only permitted in a few situations. Thin-walled metals are indeed non-flammable, but lose their load-bearing properties when exposed to extreme heat, which can lead to problems at statically relevant nodes.

If a complex knot is manufactured conventionally and without additive manufacturing, which corresponds to the state of the art, it must be individually manufactured from a large number of individual parts using complex manufacturing and assembly processes. With some geometric constellations, it is not geometrically possible to cut a perfectly form-fitting knot from the extrusion profiles.

The present invention is based on the object of overcoming the disadvantages arising from the prior art.

• - geometrisch flexibel auf unterschiedliche geometrische und statische Anforderungen eingehen,
• - möglichst geringe handwerkliche Anforderungen bei Herstellung und Montage aufweisen,
• - eine hohe Prozesssicherheit in der Herstellung mit sich bringen,
• - ein günstiges Verhalten im Brandfall aufweisen,
• - seine statischen Eigenschaften über lange Zeit unverändert beibehalten (bei Annahme eines Gebäudelebenszyklus von 50-100 Jahren), und
• - keine Wartung erfordern.

Furthermore, the object is to specify a connector for the building envelope which has at least one of the properties listed below. According to this, the connector according to the invention should:

• - respond flexibly to different geometric and structural requirements,
• - have the lowest possible manual requirements in production and assembly,
• - bring a high level of process reliability in production,
• - show favorable behavior in the event of fire,
• - Maintain its static properties unchanged over a long period of time (assuming a building life cycle of 50-100 years), and
• - do not require maintenance.

Presentation of the invention

A solution to at least one of the above-mentioned objects is achieved by a connector mentioned at the beginning, which is further developed by the characterizing features of claim 1.

According to this, the connector of the type mentioned is designed and developed in such a way that the connector has an outer shell with a cavity, the cavity being filled with a hardenable material, and that connecting pieces are provided for receiving load-bearing elements, which are located on the connector facing side extend into the curable material and are anchored therein, and which have connection means for receiving a load-bearing element on the side facing away from the connector.

An outer sheath for a connector according to the invention is specified with the features of claim 14.

A connection piece for a connector according to the invention is specified with the features of claim 15.

Advantageous refinements and developments of the invention are the subject matter of the subordinate claims.

The connector according to the invention is referred to as a hybrid connector because it has at least two different materials, namely on the one hand the outer shell and on the other hand the curable material within the outer shell. The hybrid connector according to the invention could alternatively also be referred to as a multi-material connector or as a composite material connector, without deviating from the concept of the invention.

In the context of the present invention, a connector has been created which consists of a composite of a thin-walled hollow body (outer shell) which is filled with a hardening material (in particular concrete).

The outer shell has several functions here. On the one hand, it functions as a formwork element for the hardening material and, on the other hand, it defines the external shape of the hybrid connector. The actual shape and dimensions of the outer shape depend on the subsequent facade profile system and the static, geometric and structural requirements at the later installation location of the connector. The shape is not determined by an extrusion process or similar, but has geometric freedom in all dimensions.

The shape of the outer shell preferably also controls the material distribution of the filler material in the interior of the connector. For example, specific areas can be left out that could be necessary for later cable routing through the connector, for example.

The connection of the connector (e.g. as a facade node) to the adjoining load-bearing elements (e.g. as a facade profile) is implemented via connection pieces embedded in the hardenable material, which form a force-fit connection when hardened. In the to be connected Load-bearing elements can preferably be embedded in corresponding counterparts.

The hybrid connector according to the invention is viewed as a (for the first time) practicable variant of a 3D-printed connector, which at the same time has many advantages over a conventionally produced connector.

The otherwise problematic technical complexity for the production of such a connector is converted into a complex component that can be manufactured using a standardized process. Among other things, this leads to an improved quality of execution. The saving in working time compared to the currently usual manufacturing process is immense.

The present invention combines a number of advantages. The materiality of the outer shell plays a subordinate role in the connector according to the invention with regard to the load-bearing behavior and the behavior in the event of fire. The curable material determines these two essential aspects.

There are a number of advantageous non-combustible materials for the hardenable material, the load-bearing behavior of which does not change for a long time. The designer or architect is thus free to choose the hollow body (outer shell) that gives the shape, which enables additive manufacturing processes, in particular with plastics, to be used.

In addition to the energy savings in the production of the connector, a larger installation space plays an important role for a broader field of application of the present connector.

The material thicknesses of the outer shell (hollow body) can preferably be reduced when the connector is filled with statically effective, hardenable material, which results in immense time savings in the additive manufacturing process.

In the case of additive manufacturing of the outer shell, additional, self-contained cavities can be realized which are not filled with the hardenable material. In this way, an immense weight saving is achieved in a simple manner.

When choosing the filling material, a standardized building material can be chosen, with concrete being preferred.

A “curable material” in the sense of the present invention is considered to be both a material that is still liquid or flowable, but can harden, and a material that was previously liquid or flowable but has already hardened. In this sense, “hardenability” is regarded as an inherent property of the material and is therefore not dependent on the state of aggregation.

The aspects according to the invention are discussed further below, for which purpose reference is made in part to non-limiting advantageous configurations and developments of the invention. The features of advantageous developments can be implemented individually or in any combination, thereby creating further advantageous embodiments of the invention.

In a first preferred embodiment, the connector according to the invention is a profile joint for connecting two load-bearing elements.

In a further preferred embodiment, the connector according to the invention is a node, preferably a facade node, for connecting three or more load-bearing elements.

A further development is particularly preferred in which the outer shell has plastic or consists of plastic. Such an outer shell can be manufactured, for example, by an injection molding process or a subtractive manufacturing process, or a combination thereof.

A development in which the outer shell is produced by means of additive manufacturing is very particularly preferred. As an alternative, additive manufacturing can also be referred to as 3D printing. With regard to the advantages realized in this way, reference is made to the discussions already given above.

The outer shell can preferably have varying material thicknesses as seen over its surface. Thus, the outer shell can be made more stable at particularly stressed areas, while material and weight can be saved in other areas.

Alternatively or additionally, the outer shell can have internally formed struts, these struts being formed from the same material as the outer shell. Thus, the envelope geometry can be adapted in order to positively change the behavior under stress.

The hardenable material can preferably have concrete, more preferably concrete with reinforcement. Concrete is non-flammable, weather-resistant and can withstand high pressure. The liquid concrete can easily be introduced into the outer shell, preferably through a filling opening in the outer shell, and can set there. With a With a reinforcement allowance, the hardenable material is also able to absorb tensile, compressive and bending forces of a similar order of magnitude after it has set.

In this context it is particularly preferred that the hardenable material comprises or consists of fiber concrete and / or carbon concrete. These materials are known per se and do not require any further explanation.

In a further advantageous embodiment, the connection piece has a pin or bolt on the side facing the connector which extends into the curable material.

The pin or bolt particularly preferably has a threaded pin or a threaded bolt. With the thread or a comparable surface quality, the pin or bolt can be anchored in the hardenable mass in a particularly effective and form-fitting manner.

In a further advantageous embodiment, the connector can have at least two pins or bolts on the side facing the connector, which extend into the curable material, in particular two pins or bolts having a V-shaped arrangement. With a plurality of pins or bolts, the holding force in the curable material increases. If two adjacent pins or bolts engage in the material in a V-shaped arrangement that is open in the direction of the hardenable material, the holding force in the longitudinal direction of the load-bearing part increases further, since there is a further form fit due to the inclination of the pins or bolts .

A further development of the connector according to the invention proves to be preferred in which the outer shell is designed in the area of the transition to the connection piece in such a way that it specifies the position of the connection piece in relation to the outer shell. The connection pieces to be cast are preferably fixed clearly and immovably (within a small tolerance range) in relation to or on the outer shell for the casting process of the hardenable mass.

It is particularly preferred that a connection piece can be latched and / or clicked into the outer shell. The connection pieces can preferably be snapped into place in the outer shell using suitable clips, lugs, tongues and grooves, etc. A system with snap-in rails would also be conceivable.

In a further advantageous embodiment of the connector, the connection means of the connection piece has a connection plate or is a connection plate. In this respect, a defined and stable geometry can be specified for the connection or the inclusion of a load-bearing element.

The connection means is preferably designed in such a way that the connection means enables the load-bearing element to be picked up without a stroke in relation to the direction of the longitudinal axis of the load-bearing element. This enables a connection to the connector to be established without a stroke in relation to the longitudinal direction of the load-bearing element. A hub-free production of a connection is understood to mean that no hub along the normal direction of the respective connection planes is necessary during the connection of the load-bearing element to the connector. Rather, the element can be pushed sideways to the connector and fixed there.

In this context it is preferred that the connection means for receiving the load-bearing element has a part of a dovetail connection, the part being oriented such that the dovetail connection is to be joined in a direction perpendicular to the longitudinal axis of the load-bearing element.

Alternatively, the above-mentioned hub-free connection could also be made via two plates each oriented in the connection plane, one being assigned to the connector and one being assigned to the load-bearing element, and by screwing the plates in the longitudinal direction of the load-bearing element.

The connector preferably has a filling opening for introducing the curable material, in particular wherein the filling opening is incorporated in the outer shell. This filling opening can preferably be designed in such a way that it can be closed in a watertight and / or gas-tight manner after the curable material has been introduced. Effective protection of the hardenable material from the effects of the weather can thus be achieved.

The connector can preferably have a screw channel into which screw connections can be introduced in order to fix further useful elements on the connector.

As an alternative or in addition, a channel for discharging water, in particular condensation or rainwater, can be provided. Alternatively or additionally, a channel can be provided for discharging water and / or air from the cavity of the outer shell, namely in particular to take into account chemical-physical processes during the hardening or setting of the hardenable mass.

One or more cable ducts in the connector are preferred with regard to an implementation of several functional units in a common structural environment.

The connector can furthermore have a glass receptacle, namely in particular with regard to a configuration as part of an outer facade or a window front.

A sealant joint or a sealant channel can preferably be provided in the connector, namely in particular for the convenient reception of sealant in the connection area.

Further preferred is a connector which has a bore or a bore-like recess which is positioned such that the load-bearing elements received can be fixed to the connector by means of a screw connection which is oriented essentially perpendicular to the longitudinal axis of the element and which leads through the element. In this way, load-bearing elements can be secured to the connector, possibly in addition to other precautions.
