Definitions

  • the invention relates to a heat-insulating wall, a method for creating a heat-insulating wall and a heat insulation block.
  • insulation boards it is known, for example, to apply insulation boards to the walls created using adhesive and / or dowels.
  • insulation materials with thicknesses between 4 cm and 15 cm and panel sizes up to approx. 0.5 m 2 can usually be attached to the walls.
  • a component made of expanded plastics is known from DE-GM 86 01 946, which is attached to the masonry together with other such components for thermal insulation of a wall.
  • This known component also has horizontally extending depressions which serve the better adhesion of a plaster to be applied to the outside of the component.
  • DE 34 34 021 A1 discloses a thermally insulating shaped element and a method for producing masonry, in which one layer of the plate-shaped insulating elements is plugged onto the underlying layer, and subsequently a layer of masonry is created on the inside, with projections on the heat-insulating shaped elements used to align the masonry joints.
  • good thermal insulation is one of the most important requirements for the construction of passive houses.
  • a k-value of 0.10 W / (m 2 K) is required on the outer wall.
  • This requires a thickness of an insulation layer in the range of up to approx. 40 cm.
  • such an insulation layer cannot be attached to the wall of a house using the known methods.
  • the present invention is based on the object of creating a heat-insulating wall, a method for producing a heat-insulating wall and a heat-insulating element suitable for this purpose, with the aid of which a passive house can be created inexpensively.
  • it must be ensured that thermal insulation elements with a width in the order mentioned can be securely connected to the load-bearing walls.
  • the wall according to the invention has an outer layer composed of several layers of blocks made of thermal insulation material (preferably EPS rigid foam).
  • the blocks of thermal insulation material are preferably made with a thickness of 35 cm to 40 cm, and provide excellent thermal insulation of the wall according to the invention.
  • the wall has an inner layer made of concrete or several layers of bricks, which are connected to one another with a suitable connecting means, preferably mortar. Consequently, the inner layer of the thermal barrier wall according to the invention is made in a proven manner from concrete or masonry, between which there are masonry joints that are filled with a connecting means.
  • the concrete or the connecting means located in the joints between the stones of the inner layer is used for the secure fastening of the outer layer of thermal insulation blocks to the inner layer.
  • the outer layer of thermal insulation blocks is at least partially created in front of the inner layer of concrete or masonry.
  • the concrete or the connecting means preferably mortar, which is liquid when the inner layer is created, flows into the grooves which are formed in the thermal insulation blocks on the inner sides thereof.
  • these grooves are optionally aligned with the joints between the stones of the inner layer in such a way that the connecting means can flow in without problems.
  • the concrete or the connecting agent After the concrete or the connecting agent has hardened, it is therefore partially also in the grooves of the thermal insulation blocks, so that they are firmly connected to the inner layer.
  • the thermal insulation wall according to the invention very good thermal insulation is thus ensured on the outer layer by the extraordinarily thick blocks of thermal insulation material. Furthermore, the flow of the concrete or mortar used in the creation of the inner layer into the grooves of the thermal insulation blocks ensures a firm connection between the two layers of the wall according to the invention in a completely new way.
  • the grooves of the thermal insulation blocks are spaced apart from one another in the vertical direction, if appropriate on the basis of the masonry standard, so that masonry can be combined in a standardized embodiment with the thermal insulation blocks described to form the thermal insulation wall according to the invention.
  • the thermal insulation blocks of the outer layer are not only firmly connected to the inner layer of masonry, but also a firm connection is made to the blocks below and above.
  • a tongue and groove connection has proven to be advantageous in which grooves are formed on the top and bottom sides of the blocks, into which spring elements are inserted before the next layer of blocks is placed.
  • the blocks of layers lying one above the other can be glued by applying an adhesive.
  • drawstrings are attached between individual layers of thermal insulation blocks. If the joints between the thermal insulation blocks of layers lying one above the other are aligned with the masonry joints, then another arrangement can be achieved by the arrangement of tension bands described Improvement of the connection between the inner and the outer layer can be achieved. These drawstrings are clamped between the blocks of superimposed layers and extend into the adjacent masonry joint. When the concrete or the connecting agent used, for example mortar, cures, the tapes are fastened in the inner layer. If necessary, the two layers can also be connected exclusively via the walled-in drawstrings.
  • gravity anchors are attached between the blocks of layers lying one above the other.
  • These gravity anchors preferably have a flat tab, which extends on the inside of the thermal insulation blocks to form a firm connection into the inner layer, optionally into an adjacent masonry joint. This further improves the connection between the inner and outer layers.
  • the gravity anchors have on their outward-facing side a screw bushing in which fastenings or scaffolding can be attached. Any other additional elements can also be screwed on.
  • sun protection devices or similar objects can also be attached to the outside of the thermal insulation wall according to the invention on the anchor elements described. In the area of the blocks between which such anchor elements are attached, these are flat and thermally insulated, so that no undesired heat conduction from the inside to the outside can take place via the anchor elements.
  • its outer layer also has special insulation elements which are suitable for the precisely fitting reception of windows and / or doors or their frames.
  • Such elements complement the thermal insulation system according to the invention to form a reliable thermal insulation wall and allow the creation of a complete house with an outer layer with excellent thermal insulation.
  • the thermal insulation blocks of the outer layer are provided on their outside with surface materials which ensure a good appearance.
  • Architectural materials such as ceramics, natural stone, clinker, plaster and similar materials are preferred.
  • the grooves in the thermal insulation blocks on the inside it has proven to be advantageous for the connection to the concrete or masonry of the inner layer if they are dovetail-shaped. As a result, the grooves have a groove base that is widened on the surface with respect to their width.
  • the concrete or mortar flowing into the dovetail-shaped grooves provides a particularly reliable connection between the two layers of the wall according to the invention.
  • perimeter insulation and a concrete base plate are formed in the area of the lowest layer of the thermal insulation blocks, which is flush with the upper edge of the blocks in the lowermost layer.
  • an outer layer is first at least partially created from a plurality of layers of heat insulation blocks which are placed one on top of the other and preferably consist of EPS hard foam.
  • This first method step of the method according to the invention represents a reversal of the previously usual construction sequence, in which thermal insulation in the form of panels was always attached to an already created wall.
  • the creation of an inner layer of masonry or concrete takes place after the completion of the outer layer of thermal insulation blocks.
  • the concrete or a connecting means introduced between the bricks, preferably the mortar comes into contact with the blocks of the outer layer in such a way that the two layers are connected to one another.
  • the above-mentioned steps namely the at least partial construction of an outer layer from thermal insulation blocks and the subsequent creation of the inner layer, are repeated several times in order to create a thermal insulation wall or a building from several thermal insulation walls.
  • the mortar or concrete used in the creation of the inner layer ensures a firm connection between the two layers through the measures mentioned. Furthermore, there are advantages in the method according to the invention in that the thermal insulation cover can be built up from blocks of thermal insulation material from the inside, which, compared to the work required in a conventional manner from a scaffold, makes the work easier.
  • the soil a cleanliness layer, preferably made of lean concrete, is applied.
  • the lowest layer of thermal insulation blocks is then created, and then it is preferred to install perimeter insulation in layers in the area between the walls to be created.
  • spring elements are applied in grooves on the top of the blocks before the overlying layer is placed on top, and / or that an adhesive is applied.
  • the above-described advantages can be achieved by attaching tension bands and / or gravity anchors before laying on the next layer of thermal insulation blocks.
  • the blocks of the outer layer have grooves into which concrete or the connecting means between the bricks flow when the inner layer is created.
  • a thermal insulation block is presented which is suitable for forming an outer layer of the wall of a passive house.
  • thermal insulation block according to the invention is described in claim 16.
  • the block of thermal insulation material has a sufficient width that several layers of blocks can be joined to create an outer layer of a thermal insulation wall.

  • the block according to the invention can be connected to the blocks below and above layers by means of suitable connecting means.
  • at least one groove which is preferably horizontal in the installed position, is formed in at least one side surface of the block, the position of which groove may be adapted to the position of a masonry joint of a masonry, with which several layers of blocks can be combined to form a heat-insulating wall.
  • the described formation of grooves on the side of the blocks facing the inner layer ensures a reliable connection between the two layers of the wall to be created.
  • the connecting means used in masonry, for example mortar, or the concrete used for concreting flows into the grooves described, so that after the hardening of these materials, the thermal insulation blocks are firmly anchored to the inner layer.
