Definitions

  • the invention relates to a wall component with hollow chambers and with a thermal insulation coating to increase the heat transfer resistance in the hollow chambers.
  • the invention is therefore based on the object of providing a wall component of the type mentioned at the outset which is structurally simple and has an even better thermal insulation property than the known components of this type.
  • hollow chamber inserts composed of individual hollow chamber elements are inserted into the hollow chambers, each hollow chamber element being formed from a plate and webs projecting therefrom, which keep the plates at a distance from one another, and in that the thermal insulation coating is applied to the plate surfaces is.
  • the increase in the heat transfer resistances within the hollow chambers with a thermal insulation coating has the effect that, in addition to the losses that occur due to a line heat compensation with the environment, the radiation losses of the wall components according to the invention can be greatly reduced.
  • a wall component according to the invention therefore has improved thermal insulation properties because not only conduction losses but also radiation losses are reduced.
  • the construction of these wall elements is very simple, since the hollow chamber inserts can simply be inserted into the hollow chambers of the wall component without having to be glued to the inner walls of the hollow chambers with a binder.
  • the thermal insulation coating applied to the plates of the hollow chamber elements has the effect that the radiation can emerge from the inner walls of the hollow chambers, but is greatly weakened within the hollow chambers at the hollow chamber inserts, so that there is no or only greatly reduced radiation to the outside.
  • the plates which are spaced apart by webs, divide the hollow chambers into thin layers of air between the individual plate layers, which in itself leads to a reduction in radiation. Since the plates are also provided with a thermal insulation coating, the constant alternation between thin air and thermal insulation coating achieves a very strong and effective reduction in radiation within the hollow chambers.
  • the hollow chamber inserts are composed of individual hollow chamber elements, there is the simple possibility of providing each individual plate with the thermal insulation coating and placing the individual elements on one another in layers. As a result, cavities of different sizes can be designed because the individual elements can be placed on top of one another or combined in accordance with the dimensions of the hollow chambers.
  • the hollow chamber elements can be constructed in a simple manner from cardboard lids, but can also be plastic parts. Such materials are known to have poor thermal coefficients, so that both the heat exposure and the heat radiation within the hollow chambers can be reduced.
  • the thermal insulation coating comprises metallic substances.
  • thin metal foils could be used in the specified manner in order to reduce the radiation.
  • the thermal insulation coating consists of a carrier material made of plastic and admixed metal particles.
  • the metal particles can preferably be aluminum powder.
  • Such a thermal insulation coating is easier to apply either to the inner walls of the hollow chambers or to the hollow chamber elements themselves.
  • thermal insulation coating is sprayable, so that the thermal insulation coating can be sprayed onto the inner walls of the hollow chambers and then solidifies.
  • thermal insulation coating on the hollow chamber elements is then also very simple. These are also included sprayed the thermal insulation coating and then inserted into the hollow chambers after the thermal insulation coating has solidified.
  • FIG. 1 a part of a hollow block 1 is shown in perspective.
  • This hollow block 1 consists of a solid body through which several hollow chambers 2 extend.
  • Hollow-chamber inserts 4 are arranged in the hollow chambers, which increase the thermal insulation properties of the hollow block by reducing heat losses through the hollow chambers.
  • the hollow chamber inserts 4 are shown schematically in some chambers.
  • a hollow chamber element 3 is shown partially and in perspective in FIG. 1A.
  • Each hollow chamber insert U consists of several such hollow chamber elements 3.
  • the hollow chamber elements 3 shown are made of cardboard or plastic and have a flat plate 5 from which webs 6 projecting vertically upwards and downwards. Depending on the diameter and dimensions of the hollow chambers, several such hollow chamber elements 3 can be placed one on top of the other, so that they form a hollow chamber insert 4 overall, which corresponds to the thickness and dimensions of those of the hollow chambers.
  • the hollow chamber elements 3 are provided on both sides of the plate 5 with a thermal insulation coating 7.
  • This thermal insulation coating has the property of increasing heat transfer resistance.
  • the thermal insulation coating consists of a carrier material made of plastic with an aluminum powder and was sprayed onto each individual hollow chamber element 3 on both sides of the plate 5.
  • the inner walls of the hollow chambers themselves are not covered with a thermal barrier coating.
  • the hollow chamber elements 3 assembled to form a hollow chamber insert 4 initially divided the air inside the hollow chambers 2 into thin (corresponding to the height of the webs 6) air layers.
  • a total of an alternating layering of air, the heat insulation layer 7, the plate, a matte heat insulation layer, etc. is created in the hollow chamber so that the heat radiation from the hollow chambers is greatly reduced by this constant change.
  • the inner walls 8 of the hollow chambers 2 are themselves covered with a thermal barrier coating.
  • a plurality of hollow chamber elements 3 are placed on top of one another with their webs and inserted into the hollow chambers 2.
  • the thermal insulation coating ensures that the radiation exit from the inner walls 8 is greatly reduced.
  • the subdivision of the hollow chambers 2 into thin air layers by means of the stacked hollow chamber elements further reduces the radiation. Since the hollow chamber elements are made of a material that has poor thermal conductivity, the heat conduction in the hollow chambers is also greatly reduced.
  • the thermal insulation coating can, as mentioned at the beginning, be sprayed on, but it is also possible to implement it in the manner of a film, so that, for. B. the hollow chamber elements could be coated with such a film.
  • the invention effectively leads to the fact that the thermal insulation properties of such elements are significantly improved.
  • the thermal insulation coating 7 advantageously consists of Buna rubber (polybutadiene rubber) mixed with aluminum powder.
  • the addition of aluminum powder can be up to about 20.
  • the Buna rubber is mixed with solvent and the aluminum powder so that the processing time is approx. 1 to 2 hours.
  • thermal barrier coating 7 Another advantageous mixture for the thermal barrier coating 7 consists of silicone resins and aluminum powder. Hardener is added to this mixture in an amount such that the processing or draining time is appropriate for the respective coating process (manual application or spraying).
  • a light stabilizer can be added to the mixture.
  • the mixtures mentioned can simply be mixed in a mixer or a stirrer.
