Definitions

  • the invention relates to a method for fastening thermal insulation bodies on an outer wall of a building according to the preamble of patent claim 1.
  • the wind load standard DIN 1055-4: 2005-03 regulates the technical building regulations which must be adopted for the installation of thermal insulation composite systems, which reliably absorb the wind loads in buildings, such as the wind pressure and in particular the wind suction caused by the Bernoulli effect , By the compressive and tensile forces and the adhesive bond is charged.
  • adhesive mortar with a trowel is applied to a serving for thermal insulation insulation board.
  • the adhesive mortar must be prepared beforehand: it is delivered in bags to the construction site and mixed with water by means of a mechanical mixer.
  • the still moist adhesive mortar is then applied with the trowel in a specific pattern on the insulation plate along the edges and as connecting webs.
  • the insulation panel thus treated is then attached to the façade wall or possibly to a ceiling.
  • adhesive mortar and a similar pattern of adhesive foam can be applied with a foam gun on the insulation board and glued to the facade wall.
  • the previous method with adhesive mortar or with an adhesive foam has the disadvantage that the cost of materials and the preparation time are large.
  • the bonding must be done at the right moment and at the right temperature. After application it is necessary to wait at least several days until the adhesive mortar has hardened.
  • the adhesive mortar must be prepared by means of a mechanical mixer.
  • the adhesive mortar needs about 6 kg per m 2 .
  • relatively much and heavy material has to be transported to the construction site and often hoisted on a scaffold, since the processing has to be done on site.
  • the time required for applying the insulation panels is large. It takes educated people who are able to properly apply the adhesive mortar, correctly assess the temperature, and quickly and at the right moment glue the insulation boards. Such work can only be done by professionally trained professionals.
  • the present invention has for its object to avoid the disadvantages mentioned, and to enable a simpler, faster and thus more cost-effective fastening of heat insulation bodies to an outer wall of a building and at the same time to prevent the circulation of air between the outer wall and the heat insulation body and thus the wind suction effects to avoid.
  • the inventive method has the great advantage that the entire facade can be clad in any weather and at all temperatures and temperature fluctuations with thermal insulation. Furthermore, even persons who have no expertise after a brief instruction are able to properly apply the foam and foam the insulation and adhesive foam on the heat insulation body, which is completely cured in about three hours. Since the insulation panels are already firmly mounted prior to the introduction of the adhesive foam, the facade wall has a large heat capacity, thereby temperature fluctuations are absorbed by the facade wall with a large delay, so that it is often possible to work with the foam gun even at low outside temperatures.
  • the insulation plates are already firmly mounted by the fastening device during assembly prior to the introduction of the adhesive foam, they are by the introduction the adhesive foam is not moved, which eliminates the costly reworking by regrinding the wall.
  • FIG. 1 shows a fastening device 10 in perspective view.
  • the fastening device 10 includes a fixing plate 12 for fixing the fastening device 10 to an outer wall of a building (not shown).
  • a plug-in plate 14 is connected via a connecting web 16 with the fixing plate 12, wherein the plates 12, 14 are arranged plane-parallel to each other.
  • the plug-in plate 14 is used for relative engagement, at least in sections, in a slot which is incorporated in a heat-insulating body (both not shown).
  • the insert plate 14 and the slot can be engaged relative to each other.
  • the fixing plate 12 includes a bore 18 through which a fixing element (not shown) for fixing to the outer wall can be inserted.
  • the relative engagement between the slot of a respective heat-insulating body and the plug-in plate 14 is further assisted by the lower and / or upper longitudinal side of the plug-in plate 14 being serrated.
  • FIG. 2 schematically shows a section of a heat-insulating body 20, which by the in FIG. 1 shown fastening device 10 is fixed to an outer wall 22 of a building.
  • a slot 24 extending in the longitudinal direction is introduced into the material of the heat-insulating body 20.
  • a lower (first) portion of the insert plate 14 is inserted.
  • the thickness of the slot 24 corresponds in this case to the thickness of the plug-in plate 14. This ensures a firm hold between the fastening device 10 and the heat-insulating body 20.
  • the connecting web 16 is in turn completely inserted into a recess 26 of the heat-insulating body 20, which is introduced into the heat-insulating body 20 or can be introduced on the spot. No section protrudes here of the connecting web 16 above the top of the heat-insulating body 20. Thus, it is avoided that a gap is formed between this heat-insulating body 20 and a further heat-insulating body (not shown) to be placed above it. In other words, it is thus ensured that thermal insulation bodies arranged one above the other seamlessly connect to each other without any gap. This arrangement guarantees excellent thermal insulation properties.
  • the tie bar 16 may be formed as a plate-shaped body whose lower side is flush with the lower side of the plug-in plate 14.
  • the recess 26 is formed as a slot, the thickness of which coincides with the thickness of the plate-shaped connecting web 16.
  • this slot (recess 26) and the slot 24 are identical deep introduced into the material of the heat-insulating body 20.
  • the upper side of the connecting web 16 terminates flush with the upper side of the heat-insulating body 20.
  • the material removal for the recess 26 is reduced to the minimum, whereby the heat insulating property is maximized.
  • a firm grip between the fastening device 10 and the heat-insulating body 20 is ensured.
  • the introduced into the heat-insulating body 20 as a recess 26 slot extends continuously from the slot 24 to that surface of the heat-insulating body 20, which faces in the mounted state of the outer wall 22.
  • the length of the recess 26 introduced as a slot corresponds to the distance between the surfaces of the plug-in plate 14 and the fixing plate 12.
  • the lower (first) portion of the plug-in plate 14 is engaged with the slot 24 of the heat-insulating body 20.
  • An upper (second) section of the plug-in plate 14 protrudes beyond the upper side of this heat-insulating body 20.
  • This upper portion of the plug-in plate 14 can in turn be brought into engagement with a slot of a further heat-insulating body (both not shown), which is to be placed above the heat-insulating body 20.
  • heat-insulating bodies are each provided on their bottom side with a recess for receiving a connecting web and a slot for receiving a plug-in plate from a fastening device.
  • attachment devices to be mounted on the bottom region of the outer wall are configured in such a way that the upper and lower sides of the insertion plate are flush with the upper and lower sides of the connecting web.
  • the upper and lower longitudinal side of the insertion plate 14 are formed jagged.
  • the relative engagement between the slots of respective heat-insulating bodies and the plug-in plate 14 is facilitated.
  • the prongs engage in the usually elastic material of the heat-insulating body and thus secure it more reliably against longitudinal displacement horizontal direction.
  • the fixing plate 12 is further provided with a bore (in FIG. 1 shown), through which a fixing element 28 is inserted for fixing to the outer wall 22.
  • At least one insulating element 30 is positioned in an area between heat insulating bodies arranged one above the other and the outer wall 22.
  • This insulating element 30 can be made of an elastic and porous material, for example foam, which can be easily inserted into the aforementioned area and reduces air circulation in the area between the heat-insulating bodies and the outer wall.
  • the heat insulating property is increased.
  • the insulating member 30 may be formed tubular, which hose is clamped elastically clamped between the respective heat-insulating body 30 and the outer wall 22.
  • the insulation element 30 may be provided with an adhesive surface, by means of which the insulation element 30 is glued to the back of the respective heat-insulating body 20. In both embodiments, care must be taken that the insulation element 30 is interrupted at the fastening position of the fixing plate 12 on the outer wall 22.
  • the tubular member 30 is clamped in the attachment of the heat-insulating body 20 to the outer wall 22.
  • this tubular element 30 can be fixed with the adhesive surface on the outer wall 22, before the heat-insulating body 20 are fastened with the fastening devices 10 to the outer wall 22. It is understood by those skilled in the art that the introduction of the tubular Elements 30 is quite tedious and therefore requires special skill.
  • the heat-insulating body 20 in a first step, the heat-insulating body 20, as in FIG. 3 of the WO-A-2013/023312 shown attached to the outer wall 22 of a building to be insulated, but without such tubular elements 30, wherein the heat-insulating body 20 are arranged offset from one another.
  • the fixing plates 12 of the fastening devices 10 a gap between the rear sides of the heat-insulating body 20 and the outer wall 22 is formed. This gap is typically about 0.5 cm to 1, 5 cm.
  • an in FIG. 3 foam gun 40 shown with a tubular nozzle 41 from a cartridge 42 through the heat-insulating body 20 through a liquid and curable adhesive foam between the back of a heat-insulating body 20 and the outer wall 22 hineingespritzt.
  • the lever 43 is pressed against the pistol grip 44 for a short time.
  • FIG. 4 the rear sides of the staggered heat insulation body 20 with the fastening devices 10 can be seen, wherein at various piercing points 45 of the sprayed-through adhesive foam forms circular surfaces 46, as of a sandwiched between two parallel slices of potato pancakes.
  • the foam gun can also be adjusted so that a predetermined amount of liquid adhesive foam is injected per shot.
  • the tubular spray nozzle 41 is preferably in a reciprocating rotary motion through the heat-insulating body 20 pushed through, whereby damage to the heat-insulating body, in particular by breaking out of material on the outlet side of the tubular spray nozzle is avoided.
  • the length of the tubular spray nozzle 41 corresponds to at least the thickness of the heat-insulating body 20 and is advantageously about twice as long.
  • the front end of the spray nozzle may also have a flower head shaped radial outlet to obtain a better foaming pattern. It can also be provided only a lateral outlet opening to make the foaming in a targeted direction.
  • the tubular spray nozzle 41 may have a length mark to bring the front end of the spray nozzle 41 precisely behind the heat-insulating body 20.
  • the resulting hole is also filled with foam, usually even with some excess, which is then cut off after curing.
  • a sufficient amount of adhesive foam is injected, such that the circular surfaces 46 touch and thus any air circulation is prevented.
  • the adhesive foam is not combustible with advantage.
