Definitions

  • the present invention relates to a facade system according to the preamble of patent claim 1, an assembly method according to patent claim 11 and a glass support system according to the preamble of patent claim 15.
  • Building facades consist of facade profiles with a regular or irregular geometric cross section. These facade profiles form the load-bearing part of a facade system.
  • the façade is designed to support all or part of its own weight and does not provide alternative load paths for a building's structural loads.
  • facades carry wind loads that act on the building, which include suction forces or pressure forces, but can also carry snow loads.
  • the facade profiles of the facade system support the weight of the filling elements, which are usually transparent, translucent or opaque, with the help of certain fastening elements such as glass support systems or other fastening systems. These fastening elements serve as a flat base for the filling elements and transfer their weight to the facade profile by being subjected to shear, tension and/or bending.
  • the fasteners are typically positioned into the profile channel and connected to the facade profile either by screwing, hammering or in some cases welding. In some special configurations, the fastener is docked in the channel and holds itself in place due to its geometric shape, eliminating the need for additional screws, welds, etc.
  • a profile system with thermal break means intended for glazed facades consists of intersecting internal elongated structural profile elements which are provided on their outwardly facing side with a longitudinally extending groove for receiving heads of lugs for closing window panes against the structural profile elements hold. Rubber sealing strips are arranged between the inner structural profile elements and the adjacent window panes. The sealing strips have no interruptions and are designed with a web part mounted in the grooves of the structural profile elements and with a flange part on both sides of the web part, the flange parts resting between the components on both sides of the groove and the adjacent window panes and being pressed together in a sealing manner.
  • the disadvantage of the known solutions is that the thermal insulating materials are inserted prefabricated into the grooves of the facade profiles during the production of the facade systems.
  • An object of the invention is to avoid at least one of the disadvantages of the prior art and to create a facade system in which the rigidity and load transfer behavior for a fastener is improved.
  • an improved assembly method is to be created, with which in particular the rigidity and load transfer behavior for a fastening element on an existing facade system is improved, and an improved glass support system with improved rigidity and improved load transfer behavior is to be created.
  • a facade system comprises at least one facade profile and at least one first fastening element, wherein the at least one facade profile has at least one channel-shaped receptacle for receiving the first fastening element at least in sections or is connected to at least one channel-shaped receptacle for receiving the first fastening element at least in sections, the at least a channel-shaped receptacle extends at least along the longitudinal extent of the at least one facade profile, and wherein the first fastening element is inserted and positioned in the at least one channel-shaped receptacle.
  • the at least one channel-shaped receptacle can be filled, at least in sections, with an at least temporarily flowing support means, the support means supporting the first fastening element at least in sections in the hardened state in the at least one channel-shaped receptacle.
  • the at least one channel-shaped receptacle on the facade profile can be used during production as well as during final assembly of the first fastening element of the facade system with the at least temporarily flowing support means are filled, the at least one channel-shaped receptacle being designed or shaped to hold the temporarily flowing support means locally in the liquid state at the intended support position in the at least one channel-shaped receptacle, so that the support means in the solid, hardened state, the first fastening element supports directly or indirectly, whereby the rigidity, strength and load distribution behavior in the connection between the at least one channel-shaped receptacle and the first fastening element in the facade profile is improved.
  • the at least temporarily flowing support agent can be injected, for example, into the at least one channel-shaped receptacle, for example an injection tool, for example an injection tool, being usable.
  • This enables precise filling. This means that the load distribution behavior between load-bearing and load-removing components in the facade system is greatly improved.
  • the support means which flows at least temporarily, has a finite rigidity and strength in the solid state.
  • the facade system can be a metallic or non-metallic facade profile and include aluminum, steel, wood or plastic.
  • the thick weld seam connections known from the prior art between the facade profiles and the first fastening element can be dispensed with, so that the facade profile has less material and is therefore lighter in construction and less labor-intensive. In the case of powder-coated facade profiles, subsequent welding is not desired.
  • Reducing the weld seam thickness on the facade profile not only reduces the manufacturing time and assembly time, but also improves the aesthetics of the facade.
  • the facade profile can have a regular or irregular cross section.
  • the at least one channel-shaped receptacle can be arcuate in order to complement a tubular facade profile with a circular cross section. This also applies to configurations in which the at least one channel-shaped receptacle is welded or screwed to an open profile such as a C- or U-shaped profile or similar configurations.
  • the at least one channel-shaped receptacle can have non-parallel surfaces or partially curved or straight surfaces and can be welded or screwed to the facade profile.
  • the at least one channel-shaped receptacle can be in the form of a circular, triangular, conical, trapezoidal, open or closed polygonal, partially curved shape, or have a regular geometry with several non-parallel surfaces, or have an irregular geometry.
  • the at least one channel-shaped receptacle can only consist of a groove formed from two parallel surfaces.
  • the at least one channel-shaped receptacle can be irregularly shaped, or have a fractal geometry to improve adhesion, or contain regular and irregular patterns that ensure better interaction with the at least temporarily ensure flowing support means and the first fastening element.
  • the at least one channel-shaped receptacle can be, for example, a screw channel for receiving a screw.
  • the at least one channel-shaped receptacle preferably has at least one limiting element.
  • the limiting element forms a barrier for the at least temporarily flowing support means, so that it cannot spread undesirably along the channel-shaped receptacle. This means that in the hardened state, the supporting agent only acts in the designated area in the channel-shaped receptacle.
  • the limiting element advantageously consists of an unfoamed or foamed shaped piece, such as LDPE (low-density polyethylene). Such limiting elements are easy to produce and can be easily mounted in the at least one channel-shaped receptacle.
  • the first fastening element comprises at least one glass carrier plate.
  • Glass support plates or glass supports are used so that facade filling elements rest on facades and can therefore be attached to the facade.
  • Such fastening elements have a load-bearing effect.
  • the facade glass is additionally fixed to the facade with glazing beads or connecting buttons.
  • the aforementioned facade system with a glass support plate as the first fastening element improves the load transfer in the facade system.
  • the horizontal and vertical load transfer and stabilization of inclined and horizontal glazing elements are also improved with the glass support plate.
  • the first fastening element can be made of steel, stainless steel, bronze, magnesium alloys, aluminum or non-metallic materials such as thermoplastics, high-strength polymers, or organic materials such as bamboo, wood, conditioned/unconditioned wood or composite materials such as fiber-reinforced polymers.
  • the first fastening element can be inserted and positioned into the at least one channel-shaped receptacle in the direction perpendicular to the longitudinal extent of the facade profile.
  • the first fastening element therefore does not have to be retracted, pushed in or inserted along the longitudinal extent of the channel-shaped receptacle, as is known.
  • This enables simple assembly, whereby the first fastening element can be positioned precisely in the at least one channel-shaped receptacle from the outside towards the support position in the at least one channel-shaped receptacle in order to be stabilized in a subsequent step with the at least temporarily flowing support means. Retrofitting existing facade systems with fasteners is simplified.
  • a second fastening element is present, which is inserted and positioned in the at least one channel-shaped receptacle, the support means being in the hardened state, the second fastening element is directly supported at least in sections. This further improves the strength and rigidity in the connection between the at least one channel-shaped receptacle and the first fastening element in the facade system.
  • the second fastening element preferably accommodates the first fastening element at least in sections.
  • the second fastening element supports the first fastening element, so that there is a further improvement in the rigidity in the facade system.
  • larger load capacities for example heavy glazing, can be carried by the fastening elements.
  • the second fastening element is a clamping foot or a sliding block, clamping button or the like
  • the first fastening element is a glass support plate or a support plate.
  • the clamping foot enables the glass support plate or the support plate to be supported in terms of area along the edge of the at least one channel-shaped receptacle, so that larger load capacities and rigidities in load transfer are possible.
  • At least one of the two fastening elements has at least one fastening sleeve for receiving a fastener, the fastening sleeve penetrating at least sections into the at least one channel-shaped receptacle.
  • a fastening sleeve is also a receiving opening for receiving a fastener, for example for a bolt, for a screw or the like. This means that at least one of the two fastening elements can be positioned in the at least one channel-shaped receptacle using a point contact or several point contacts.
  • the support means directly supports the fastening sleeve and/or the fastening means in sections, so that the rigidity and strength in the connection between the at least one channel-shaped receptacle and the fastening sleeve and/or the fastening means in the facade system is improved.
  • the hardened support means presses on the fastening sleeve and/or on the fastening means, so that they cannot be pulled out of the at least one channel-shaped receptacle. This prevents the occurrence of localized plastic zones, so that the rigidity and strength is further improved and the connection becomes more compact overall.
  • At least one of the fastening elements and/or the at least one facade profile has at least one opening for filling the at least temporarily flowing support means.
  • An opening on the facade profile can also be designed as a fill level control opening, so that the amount of support agent that is to be filled and flows at least temporarily can be easily controlled.
  • An opening on the first Fastening element can serve to position the at least temporarily flowing support means and at the same time use the opening as a fastening opening for a fastening means.
  • At least one of the fastening elements has an external surface structuring, so that the connection between at least one of the fastening elements and the support means is improved in the hardened state.
  • the support means can adapt to the external surface structure in the flowing state, so that a relative movement between the support means in the hardened state and the external surface structure is prevented due to the static friction or positive locking or mechanical locking or toothing that occurs.
  • At least one of the fastening elements has an internal surface structuring, so that the connection between at least one of the fastening elements and a fastening means or the support means is improved in the hardened state.

  • the contact surfaces of the first fastening element, without supporting means generally do not have uniform contact in the at least one channel-shaped receptacle over the embedded channel length and therefore have individual support points. In such cases, localized plastic zones can form on the connecting parts and the connection as a whole has limited stiffness and strength. This leads to an uneven load distribution between the contact surfaces of the connection.
