Definitions

  • the invention relates to a method for isolating building parts and building internals having cavities against warm and cold, in which a debris-capable, inorganic, highly porous thermal insulation material is pneumatically demanded in a hose and blown into the cavities by means of excess pressure, thereby compressing and solidifying
  • DE-A-4438627 teaches the use of an insulating material which consists of a mixture of ex-dilated pearlite and an aqueous solution of alkali silicates. In contrast to the generic method, this mixture is produced at the factory. It is disadvantageous that the mixture can only be kept for a limited time. Solidifying the mixture requires a mechanical compression process
  • DE-A-3534706 describes a packaging material using expanded pearlite or vermiculite, which is bonded to a shaped body by means of an inorganic or organic binder.
  • a shaped body by means of an inorganic or organic binder.
  • the molded body should be able to absorb shocks elastically or plastically.
  • DE-A-4439428 suggests the introduction of thermal dam material into cavities e.g. Roof cavities of buildings in front, whereby inorganic fillers and solids are forced into the cavities by means of compressed air.
  • the required mass, which contains perlite, should be earth-moist.
  • the thermal insulation material is also introduced here continuously. However, it is not said how the sealing between the inlet funnel and the delivery line is to be carried out Has.
  • the US-A-2,200,713 shows a method for introducing granular or fibrous Isoliermate ⁇ al in cavities of buildings using a narrowing pipe at the outlet end of a hose line.
  • the constriction is intended to increase the pressure, but this is physically questionable because of a cross-sectional constriction of the Although the outlet nozzle has an increased speed, it is hardly possible to increase the pressure.
  • the insulating debris is continuously fed into the delivery line as in the prior art mentioned at the outset, so that the same disadvantages are present.
  • the object of the invention is to propose a method of the type mentioned, which can be carried out with a simpler and easily transportable device and which allows the use of a higher delivery pressure in order to ensure pneumatic consolidation when the material is introduced into the cavities
  • This object is achieved in a method of the generic type in that diatomaceous earth, perlite, magnesium silicate or vermiculite or mixtures are used as the thermal insulation material is used therefrom, an amount of the dry thermal insulation material is mixed in a mixing chamber with a recipe-related amount of an aqueous inorganic binder to form a sticky dry matter, this mixture is transferred to a pressure-free closed container to which the delivery hose is connected, opposite the container the mixing chamber and the delivery hose is shut off and placed under high pressure in the range of 2 to 10 bar, after which the shut-off of the delivery hose is opened and the batch is blown into the cavity under this high pressure, with a cohesive, completely filling the respective cavity after curing , stable insulating molded body is formed.
  • the method according to the invention works discontinuously in that the bulk heat insulating material is introduced into a pressure-free container, which is then shut off by means of a simple shut-off device, after which the delivery pressure is built up in the container by means of a compressor.
  • the delivery pressure can be selected to be significantly higher than with a continuous process, whereby two advantages are achieved simultaneously.
  • considerably more bulk material can be conveyed per unit of time, which compensates for the disadvantage inherent in a discontinuous process that the actual insulation process is interrupted during the loading of the container, and therefore time is lost.
  • the second advantage concerns the way in which the sticky mass is introduced into the cavities and this advantage is decisive for the result of the work.
  • the mass can be injected into the cavities in any direction, including upwards, and when the mass particles injected at high speed strike, there is an intimate connection with the existing surface.
  • the high delivery pressure also allows the particles to be shot into narrow and even angled channels, so that "dead corners" are also reached.
  • silica sol 40% by weight are mixed with a mixture of 40% by weight of perlite, particle size 2 mm and 20% by weight of vermiculite, particle size 1 mm.
  • This thermal insulation compound is particularly suitable for refractory linings.
  • the bulk density of vermiculite is higher than that of perlite and the surface structures are different, which leads to a higher binding capacity.
  • Example 4 A mixture of 30% by weight perlite, particle size 1 mm and 30% by weight magnesium silicate is mixed with 40% by weight loam water. The result is a particularly cost-effective thermal insulation material that can be used without any problems for normal insulation purposes.
  • FIG. 1 shows a schematic view of a device suitable for carrying out the insulation process
  • FIG. 3 shows a cross section in the roof area of a building with a representation of the rafters spaces to be filled with insulating material
  • FIG. 5 shows the cross section of a double-skin drywall, which according to the invention is provided with a heat-sound insulation, and
  • FIG. 6 shows the cross section of a chimney with a drawn-in stainless steel pipe, the annular space outside this pipe receiving the thermal insulation filling.
  • a pressure vessel 10 is connected via a lock 12 to a loading hopper 14 above it.
  • the funnel has a suspension frame 16 for a big bag 18, shown in broken lines, which contains a pearlite filling.
  • the lock 12 and the funnel 14 form a structural unit which can be detached from the pressure container 10, so that both parts can be transported separately.
  • a dosing screw 20 protrudes into the lock 12 and has a motor drive, which is not shown here.
  • a separate pressure vessel 22 there is an aqueous binder or a mixture of binders.
  • This vessel 22 is connected via a connecting line to injection nozzles 24 which open out circumferentially offset in the lock 12.
  • injection nozzles 24 lie in a plane below the metering screw 20, but it goes without saying that, in the practical embodiment, the injection nozzles 24 open out in the area of the metering screw 20 and here preferably also at axial intervals.
  • the connection of the lock 12 to the pressure vessel 10 can be closed in a pressure-tight manner by means of a shut-off element 26.
  • a compressed air line 28 opens into the pressure container 10 and is supplied by a compressor 30 in order to be able to build up pressure in the pressure container 10.
  • a pressure line 32 connects to the pressure vessel 10, which is designed as a flexible pressure hose of approximately 50 mm in diameter and should have a sufficient length to be able to reach the roof of a building with the outlet end when the device is parked on the ground.
  • a shut-off valve 34 At the outlet end of the delivery line 32 there is a shut-off valve 34 to which a flexible or articulated lance 36 with a narrowing outlet nozzle 38 is connected.
  • the lance has a length of at least 2 m and can be inserted, for example, through a hole 40 in a ceiling cladding of a roof into the space between the rafters, the lance 36 being bent so that the nozzle 38 can be adjusted parallel to the direction of the rafters.
  • the operation starts by driving the metering screw 20, so that pearlite beads with a predetermined amount per unit of time pass from the hopper 14 through the lock 12 into the pressure vessel 10.
  • binder is injected into the material stream through the nozzles 24 and thereby equally distributed.
  • the vessel 22 is connected to the running compressor 30, so that there is a supply pressure in the vessel which supplies the binder to the dam material.
  • the granular material entering the pressure vessel 10 has a sticky surface.
  • the screw 20 After filling the pressure vessel 10, the screw 20 is stopped at the same time, the outlet valve (not shown) for the binder in the vessel 22 and the butterfly valve 26 of the pressure vessel 10 are closed, and the compressor 30 from the vessel 22 the pressure vessel 10 is switched over, so that pressure builds up in the pressure vessel 10 As soon as the operating pressure is reached, the compressor 30 switches off under pressure control and by opening the shut-off valve 34 at the end of the delivery line 32 the sticky dry matter can be injected. Due to the narrowing nozzle 38, a material seal enters the lance and the sprayed-out material further compresses the material already present when it strikes, the density being increased by at least 10% to 35% depending on the desired properties of the insulating body to be produced.
  • the hole 40 can be located, for example, on the middle roof height, so that the insulating compound is first injected to the eaves side and the lower cavity is filled, after which the nozzle 38 is directed towards the ridge in order to fill this space downwards. In this way, one cavity after the other is isolated.
  • the compacted dam mass tries to relax and expands, so that the mass penetrates even into the smallest free corners and no air cavities remain.
  • the injected mass solidifies into a dimensionally stable dam body with a high thermal insulation value
  • Shaped body is sufficiently load-bearing so that the previously cut out plate can be reinserted into hole 40 and glued to the shaped body so that the assembly point only needs to be filled
  • the method according to the invention can also be used - at least in some areas - to produce very thin-walled insulating bodies which, for example, have a small wall thickness of only a few centimeters in the annular space between a cylindrical stainless steel tube and a square chimney shaft Provide an access opening 40 on each floor to ensure that an uninterrupted insulating body is created which extends over the entire height of the chimney

Abstract

Du matériau perlitique sec granuleux est introduit par en haut, sous forme dosée, à l'aide d'une vis sans fin de dosage dans un réservoir à pression (10) pouvant être relié à un compresseur (30). Simultanément ledit matériau perlitique est mélangé à un liant aqueux inorganique provenant d'un réservoir d'alimentation (22). La masse sèche collante qui en résulte est mise sous pression dans le réservoir à pression (10) et est acheminée jusque dans une cavité d'un bâtiment par l'intermédiaire d'une conduite de transport (32). La matière isolante est injectée dans la cavité à l'aide d'une lance flexible située à l'extrémité de la conduite de transport (32) et est simultanément compactée. Après durcissement, on obtient un corps isolant aggloméré indéformable à haut coefficient de calorifugeage.
