Definitions

  • the invention relates to a lightweight facade component according to the preamble of claim 1.
  • the invention also relates to a facade construction with such a lightweight facade component.
  • a generic facade lightweight component is known.
  • This contains a frame consisting of frame profiles onto which a prestressed film made of fluoroplastic is shrunk.
  • the film is designed as a shrink tube, which is placed on the frame and shrunk on by heating.
  • the production of such facade elements is relatively expensive.
  • the object of the invention is to create a lightweight facade component and a facade construction with such a lightweight facade component that can be produced more easily and allow a large scope for design.
  • the facade lightweight construction element according to the invention contains a frame formed from frame profiles, an outer membrane arranged on the outside of the frame profiles and an inner membrane arranged on the inside of the frame profiles, wherein the Outer membrane and the inner membrane are held by releasably fastened clamping elements on the frame profiles.
  • facade modules that are easy to prefabricate can be created in a membrane construction, in which a thermal separation can be achieved not only between the outer and inner membrane, but also in the connection to the supporting elements of facade constructions.
  • the outer and inner membrane can simply be placed on the frame and easily and securely attached to the frame profiles by the clamping elements via a clamp connection.
  • the lightweight facade component can thus be prefabricated as a standardized, individually designable and cost-effective component that offers a large number of different design options.
  • the frame profiles of the lightweight façade element are designed in one piece or, in an embodiment that is particularly advantageous for the thermal separation, consist of an outer profile with an inner profile connected to this via insulating bars.
  • the clamping elements are expediently arranged in a form-fitting manner in recesses on the outside and inside of the frame profiles. As a result, the outer and inner membranes can be held separately from one another in a simple yet secure manner by clamping to the frame profile.
  • the clamping elements can have a holding profile for form-fitting holding on the frame profile and a clamping profile for holding the outer membrane or the inner membrane by clamping on the frame profile.
  • the clamping elements can be attached to the frame profile in different ways. For example, it can be attached using a strip-shaped clamping piece that engages over a locking lug on the clamping element and a corresponding locking lug on the frame profile in the manner of a clip connection. However, the clamping elements can also be screwed to the frame profile or connected to it in some other suitable manner.
  • an LED light band or another light source can be arranged on the inside of the frame profile, for example. This allows variable lighting effects to be created as required.
  • Latching lugs for attaching a diffuser can also be arranged on the frame profile.
  • between the A plate component held on the frame profiles by means of holding webs can be arranged between the outer membrane and the inner membrane.
  • the plate component can be a polycarbonate or PMMA multi-wall plate, for example.
  • Such panel components can serve as heat or sound insulation and can also affect the appearance.
  • suitable grooves for receiving a holding part for attachment to a facade construction are provided on the frame profiles.
  • At least one supply duct for the air supply is arranged in the frame profiles. If required, fresh air can be fed into the interior of the lightweight facade component via the supply duct, thus avoiding the formation of condensation in the interior of the lightweight facade component caused by temperature differences between the exterior and interior areas. If the lightweight façade elements are supplied with cleaned and dried air, damage caused by condensation, such as dirt, mold growth or leaks, can be avoided. This can be implemented using a blower with an integrated air dryer. The outside climate can be constantly monitored by a control device and the amount of dry air can be adjusted accordingly. By integrating the air supply into the frame profile, an air supply that is as invisible as possible from the outside can be achieved.
  • the invention also relates to a facade construction with a support profile to which at least one lightweight facade component described above is fastened in a sealed manner by a holding profile via an inner seal and at least one outer seal.
  • An air supply can expediently be arranged on the support profile.
  • the air supply can include a first pipe bend connected to the frame profile and a second pipe bend fastened to the support profile.
  • the facade construction shown comprises a support profile 1 to which two lightweight facade components 2 are fastened in a sealed manner using a retaining profile 3 designed as a pressure strip via an inner seal 4 and outer seals 5 .
