Definitions

  • the invention relates to a method and a device for carrying out the method for isolating cavities Building parts and building installations against heat and cold, in which a pourable, inorganic, highly porous thermal insulation material in a hose pneumatically conveyed and blown into the cavities by means of overpressure and thereby is compressed and solidified.
  • GB 871 635 A describes a method and a device for the entry of Insulating powder, e.g. Perlite or vermiculite, in cavities.
  • Insulating powder e.g. Perlite or vermiculite
  • the insulating powder is by means of a Venturi nozzle sucked into the delivery line and conveyed to an insertion lance. Lack of overpressure at the outlet end of the delivery line is compression and Solidification of the insulating material in the cavity to be filled is not possible
  • DE 3534706 A describes a packaging material using Expanded pearlite or vermiculite, which by means of an inorganic or organic Binder is glued to a shaped body. Also here is the addition of cellulose addressed. The molded body should be able to absorb shocks elastically or plastically. With regard to a method for introducing thermal insulation material into cavities nothing else can be found in this document.
  • DE 4439428 A proposes the introduction of thermal insulation material into cavities e.g. Roof cavities in buildings, using inorganic fillers and solids Compressed air is conveyed into the cavities.
  • the extracted mass containing perlite supposed to be damp.
  • the thermal insulation bulk material is also introduced here continuously. However, it is not said how the seal between input funnels and delivery line has to take place.
  • US 2,200,713 A shows a method for introducing granular or fibrous Insulating material in building cavities using a narrowing Pipe at the outlet end of a hose line. Due to the narrowing one should Pressure increase can be achieved, but this is physically doubtful because of a Cross-sectional constriction of the outlet nozzle increases the speed but hardly a pressure increase can be achieved.
  • the insulation bulk material is also entered here continuously into the delivery line as in the prior art mentioned at the beginning, so that the same disadvantages are present.
  • the object of the invention is to propose a method of the type mentioned at the outset, that can be carried out with a simpler and easily transportable device and which allows the use of a higher delivery pressure to ensure that the material is introduced to ensure pneumatic consolidation into the cavities.
  • the method according to the invention works discontinuously in that the bulk heat insulating material is placed in an unpressurized container, which is then by means of a simple Shut-off device is shut off, after which the delivery pressure in the compressor Container is built.
  • the discharge pressure can be significantly higher be chosen as in a continuous process, with two advantages at the same time can be achieved.
  • significantly more bulk goods can be conveyed per unit of time, which compensates for the disadvantage of a discontinuous process in principle adheres to the fact that the actual insulation process during loading of the container is interrupted, so time is lost.
  • the second advantage concerns the type of Introducing the sticky mass into the cavities and this advantage is for that Work result crucial.
  • the mass in any directions, including upwards into the cavities and at Impingement of the mass particles shot in at high speed finds one intimate connection with the existing exposure surface instead.
  • the height Delivery pressure also allows the particles to be shot into narrow and even angled ones Channels so that "dead corners" can also be reached.
  • silica sol 40% by weight are mixed with a mixture of 40% by weight of perlite, particle size 2 mm and 20 wt.% vermiculite, grain size 1 mm mixed.
  • This thermal insulation mass is especially suitable for fireproof linings.
  • the bulk density of vermiculite is higher than that of perlite and the surface structures are different, resulting in a leads to higher binding capacity.
  • a mixture of 30% by weight perlite, grain size 1 mm and 30% by weight magnesium silicate 40% by weight of loam water is added.
  • the result is a particularly inexpensive one Thermal insulation material that can easily be used for normal insulation purposes.
  • a pressure vessel 10 is above a lock 12 with a Feed hopper 14 connected.
  • the funnel has a suspension frame 16 for one dashed-dotted big bag 18, which contains a pearlite filling.
  • Lock 12 and the funnel 14 form a structural unit which is detachable from the pressure vessel 10, so that both parts can be transported separately.
  • Dosing screw 20 which has a motor drive, which is not shown here.
  • aqueous binder or Binder mixture there is an aqueous binder or Binder mixture.
  • This vessel 22 is via a connecting line with injection nozzles 24 connected, which open circumferentially offset in the lock 12. From graphic For reasons, these injection nozzles 24 lie in a plane below the metering screw 20, however, it goes without saying that in practice the injectors 24 are in the range the metering screw 20 and preferably also open here at axial intervals.
  • the Connection of the lock 12 to the pressure vessel 10 is by means of a shut-off device 26 can be closed pressure-tight. In the pressure vessel 10 opens a compressed air line 28, the a compressor 30 is supplied to build up pressure in the pressure vessel 10 can.
  • a delivery line 32 connects to the pressure vessel 10 is designed as a flexible pressure hose of about 50 mm in diameter and one should be of sufficient length to with the device parked on the ground to be able to reach the outlet end of the roof of a building.
  • a shut-off valve 34 At the outlet end of the Delivery line 32 is a shut-off valve 34, to which a flexible or articulated lance 36 with narrowing outlet nozzle 38 connects.
  • the lance has one Length of at least 2 m and can be e.g. through a hole 40 in one Retract the ceiling cladding of a roof into the rafter space, whereby the lance 36 is bent so that the nozzle 38 is set parallel to the rafter direction can be.
  • Operation starts by driving the metering screw 20 so that the hopper 14 Pearlite granules with a predetermined amount per unit of time through the lock 12 in the Pressure vessel 10 arrive.
  • Binder is injected through the nozzles 24 into the material flow and is evenly so distributed.
  • the vessel 22 is connected to the running compressor 30, so that there is a delivery pressure in the vessel that binds the insulation material feeds.
  • the granular material entering the pressure vessel 10 is sticky Surface.
  • the screw 20 After filling the pressure vessel 10, the screw 20 is simultaneously stopped the outlet valve, not shown, for the binder in the vessel 22 and Butterfly valve 26 of the pressure vessel 10 closed and the compressor 30 from the vessel 22 switched to the pressure vessel 10, so that now a pressure build-up in the pressure vessel 10 takes place.
  • the compressor 30 pressostatically controlled - and by opening the shut-off valve 34 at the end of the Conveying line 32, the sticky dry matter can be injected.
  • narrowing nozzle 38 occurs in the lance material compression and the sprayed Material continues to compress the existing material when it hits it Density by at least 10% up to 35% depending on the desired properties of the insulating body to be produced is increased.
  • the Hole 40 can be located, for example, on the middle of the roof, so that the first Insulating compound is injected towards the eaves side and the lower cavity is filled, after which the nozzle 38 is directed towards the ridge to grow this space downwards to fill. In this way, one cavity after the other is isolated.
  • the compacted insulation mass tries to relax and expands, so that the mass penetrates into the smallest free corners and none Air voids remain.
  • the injected is Mass solidified into a dimensionally stable insulating body with a high thermal insulation value. This Shaped body is sufficiently load-bearing so that the previously cut plate back into the Hole 40 can be inserted and glued to the molded body, so that the assembly point only needs to be filled.
  • FIG. 6 can also be illustrated with the method according to the invention - at least in some areas - quite thin-walled molded insulating bodies are produced in cavities e.g. in the annulus between a cylindrical stainless steel tube and a square chimney shaft with a minimum wall thickness of just a few centimeters exhibit. For higher fireplaces, it is advisable to have one on each floor Provide access opening 40 to ensure that a full chimney height reaching uninterrupted insulating body.
