Definitions

  • the invention relates to a hollow block according to the preamble of claim 1, a method provided for its production according to the preamble of claim 11 and a device provided for carrying out this method according to the preamble of claim 22.
  • the first way of improving the thermal insulation of a hollow block is to reduce its bulk density, ie its stone weight and thus its mass in the dry state, and thus also to increase its hollow chambers, since a lower bulk density improves the thermal insulation.
  • a lower bulk density improves the thermal insulation.
  • the bulk density of the stone can only be reduced to a certain limit in order to achieve the necessary stone strength.
  • This lower one With regard to the bulk density, the limit is around 0.5 kg / dm 3, in special cases at 0.4 kg / dm 3 .
  • the second known possibility of improving the thermal insulation of a hollow block is that the outer surface of the hollow block is subsequently coated with a light thermal insulation layer, which consists, for example, of polystyrene and is applied at the construction site to the hollow block walls produced in a previous separate operation.
  • a light thermal insulation layer which consists, for example, of polystyrene and is applied at the construction site to the hollow block walls produced in a previous separate operation.
  • the third known possibility of improving the stone thermal insulation consists in the production of double-skin walls, in which the outer thin wall shell essentially takes over the weather protection, with thermal insulation material being introduced wholly or partly into the cavity formed between the two wall shells, for example by Polystyrene mats or by foaming this cavity with so-called UF foam or aminoplast foam.
  • thermal insulation possibilities mentioned above in second and third place lies in the fact that the thermal insulation is installed at the construction site with the high wages required for such work, so that it is therefore generally very cost-intensive.
  • these possibilities include the usual sources of error and imponderables that every manual activity without plant control entails. H. there is a risk that the quality of such thermal insulation is often inadequate.
  • the fourth known possibility of improving the thermal insulation of a hollow block consists in introducing thermal insulation materials into the hollow blocks during their manufacture in the factory.
  • This type of thermal insulation is known today under the term "integrated thermal insulation” and summarized with regard to its various variants in the essay "Thermal insulation of external walls, stone systems with integrated insulation layer” by F. Hohwiller, Bad Dürkheim, magazine “Betonwerk und Fertigteiltechnik", booklet 1 or 2/1980.
  • the known measures carried out for the purpose of the so-called "integrated thermal insulation” are based without exception on the material polystyrene, which has the desired property that it offers a relatively high resistance to the air passing through the stone wall.
  • this resistance is described with the term vapor diffusion resistance, expressed by the vapor diffusion resistance number.
  • the vapor diffusion resistance number of, for example, lightweight concrete stones, such as pumice concrete stones, is between 5 and 10, depending on their bulk density, while the vapor diffusion resistance number of polystyrene is 6 to 20 times the aforementioned value; when using a hollow block designed in this way with an integrated thermal insulation based on polystyrene, the air exchange between indoor and outdoor air is therefore restricted.
  • both of the aforementioned materials namely polystyrene and UF foam
  • the relevant fire protection standard according to DIN 4 102 basically differentiates between non-flammable and flammable substances. Within these two groups of substances there are again differentiations according to the level of flammability. So A distinction is made, for example, in the area of flammable substances according to group B 1 (flame-retardant), B 2 (normally flammable) and B 3 (highly flammable).
  • the invention is concerned with a hollow block with integrated thermal insulation.
  • the invention has for its object, in such a way to design the hollow block of the generic type to eliminate the disadvantages with integrated thermal insulation, that he a non-combustible and non-shrinking, however, however, cheap in use
  • coateddä l nm Materials can be provided with thermal insulation in a simple and energy-saving manner at the place of stone production and also have a consistently good thermal insulation effect over a long period of time.
  • the invention is also intended to provide a method for producing such a thermally insulated hollow block and an apparatus for carrying out this method.
  • the hollow block designed according to the invention has the great advantage compared to the known thermally insulated hollow blocks that its thermal insulation can be produced automatically and inexpensively in the factory, since only a small proportion of wages is incurred, and the extent of thermal insulation is increased as desired and therefore the increasing energy prices step can be adjusted for step.
  • the heat-insulating material used according to the invention which consists of mineral fibers, preferably in flake and / or granulate form, has the great advantage over the polystyrene or UF foam or aminoplast foam used hitherto that it is not only a non-shrinking material, but is also non-flammable.
  • the mineral fibers provided according to the invention as thermal insulation filling which can consist of glass fibers, rock wool, basalt wool, granite wool or the like, are, as the name suggests, a mineral, that is to say a non-combustible material that complies with the fire protection standard according to DIN 4 102 is classified in the group of non-combustible building materials.
  • the Hollow block according to the invention can not lose its thermal insulation in the event of fire, as is the case when using polystyrene or UF foam as thermal insulation, so that the mineral fiber filling of the hollow block according to the invention is not only an extremely inexpensive material, but also none in the event of fire Can be damaged.
  • the vapor diffusion behavior of such a hollow block is extremely favorable because the vapor diffusion resistance number of mineral fibers is in the range of the values of conventional hollow blocks or even lower, so that the water vapor does not pass through the stone chambers filled with mineral fibers, especially with mineral fiber flakes or granules Way is prevented or restricted.
  • the ongoing drying of such a hollow block can thus take place without restriction, and practically as if its chambers had not been filled.
  • the mineral fiber filling according to the invention can be used with hollow blocks of any material, such as lightweight concrete blocks, gas concrete blocks, bricks, sand-lime bricks and the like.
  • it preferably consists of mineral fiber flakes or granules, e.g. B. according to DIN 18165, sheet 1, "fiber insulation for the building industry 11, which is obtained by crushing by means of grooved rollers or similar devices, such as chopping machines, etc. from a corresponding fleece, felt or mat with possibly subsequent loosening and thus prefabricated in an advantageous manner can be.
  • the mineral fiber filling can be introduced into the stone chambers of the hollow blocks of the invention are carried out pneumatically, it being expedient to introduce the, for example, flake-shaped mineral fibers from above with compressed air into the chambers which are then necessarily open on both sides of the hollow block block which is closed on the underside by a sieve, a grid or the like.
  • a vacuum can also be used, the latter also being able to be combined with the use of compressed air.
  • the mineral fiber filling is introduced by means of a plug, in particular by means of a plug, whereby the desired extent of the mineral fiber filling in the stone chambers can also be achieved in a simple and easy manner.
  • the hollow block In order to be able to equip the hollow block with the thermal insulation according to the invention, it is essential to use one whose chambers naturally have at least one side. are open. For heat protection reasons, however, it may be appropriate to keep these chambers open on both sides in order to avoid cold bridges. In any case, it is advantageous to provide the chambers of the hollow block, regardless of whether they are open on one or both sides, with a seal that prevents the metered mineral fiber material from slipping out or that mortar or water gets into the mineral fiber filled stone chambers.
  • the hollow block designed according to the invention not only has a simple, easy and inexpensive production, since in order to provide it with the desired thermal insulation, no thermal energy is required and only a simple one, because only a mechanical filling process has to be carried out, but it He also uses a cheap thermal insulation material that has an outstanding and consistently good thermal insulation effect over a long period of time.
  • the method according to the invention provided for producing the hollow block described can be carried out not only in a simple and energy-saving manner, but also with an automated process. In practice, it must be taken into account that in the production of, for example, lightweight concrete blocks in the modern, large production facilities, ten hollow block blocks measuring 49 x 24 x 23.8 cm or eight hollow block blocks measuring 49 x 30 x 23.8 cm are produced in one operation which is about 20 seconds. The speed of the method according to the invention must be based on this work cycle. This is a particular difficulty, which is, however, solved with the method according to the invention.
  • the hollow blocks are - in the case of steam or warm air hardening after leaving the steam or warm air chambers and in the case of pure air hardening after completion of the air hardening - via push tracks or similar transport devices to the final package animals departed. In this phase, they go through the process according to the invention and are therefore equipped with the desired integrated thermal insulation without there being any delay in the workflow.
  • the ready-made or factory-made mineral fiber material is preferably stored in the form of mineral fiber flakes or granules in a storage container serving as a preliminary silo, from where it falls into a filling truck, which is used to fill a dosage form that is fixed above the stones, if not a dosage form that can be moved between the storage container and the stones is used, which makes the use of a separate filling car unnecessary.
  • the dosage form makes it possible to maintain an exact amount of mineral fiber in order to obtain exactly the desired mineral fiber filling. It is of central importance for the integrated thermal insulation of the finished hollow block that only loosely introduced mineral fibers bring about the desired insulating effect.
  • this device according to the invention is not only of simple and robust design, but is also capable of working automatically and quickly, i. H. So completely adapt to the work cycle specified in the actual stone production.

  • the drawing plate 113 is drawn from the closed position according to FIG. 9 in the direction of arrow 114 into the position according to FIG. 10, so that the through openings 110 of the dosage form 107 become open on the underside.
  • the upper hood 108 is moved vertically downward in the manner shown in FIG. 11 in the direction of the dosage form 107, in such a way that the dosage form 107, which is preferably spring-suspended for this purpose, is pressed onto the hollow blocks 1 such that the between the bottom of the dosage form 107 and the top of the hollow blocks 1 formed gap 115 only has an order of magnitude of about 1-2 mm.
  • the lower hood 137 is moved upward, so that its grating 136 closes the underside of the hollow blocks 1.
  • the inside of the upper hood 108 is pressurized with compressed air via the compressed air connection 134, so that the mineral fiber quantity 4b located in the dosage form 107 is inevitably pneumatically pressed into the stone chambers 2 of the hollow blocks 1, that is to say pneumatically introduced by blowing.
  • This pneumatic insertion process can be carried out with a reliable function, because on the one hand the upper hood 108 sits relatively close to the top of the dosage form 107 and on the other hand the minimal gap 115 still present between the underside of the dosage form 107 and the top of the hollow block stones 1 represents a kind of relief gap that one counteracts excessive build-up of overpressure and at the same time enables the necessary removal of excess compressed air.
  • the grating 136 which closes the underside of the hollow block stones 1 during the insertion process serves both to prevent the mineral wool 4b from being discharged from the lower ends of the hollow block chambers 2 and to allow any excess compressed air to be removed.
  • the lower hood 137 can be subjected to a more or less strong vacuum via its air connection 138.
  • the upper and lower hoods 108, 137 are relieved of the excess pressure or vacuum and moved away from the dosage form 107 or the hollow block stones 1 in the vertical direction, so that they return to the position shown in FIG. 10.
  • the lower hood 137 can then be pressurized with compressed air via the connection 138, in order in this way to clean both the lower hood 137 and the grid 136 of mineral fiber flakes 4.
  • the dosage form 107 can now be moved for a new filling operation into the position according to FIG. 8, in which its underside is closed by the drawing plate 113 still located there, but its top is connected to the lower discharge end 119 of the filling box 118.
  • the hollow block stones filled with the mineral fiber flakes 4b are now moved back to the pallet 6 by the tensioning frame 106 from the position according to FIG. 11, but are sprayed on the way there both on the upper side and on the lower side by the spray device 124 according to FIG. 12, which the spray device 24 6 and also has two spray tubes 125, 127 which are arranged at a horizontal spacing and are connected to one another by a supply pipe 125 and which are provided with spray nozzles 128 facing one another.
  • Spray nozzles 128 of the spray device 124 which can be moved in a corresponding manner are then sprayed with a hardenable material layer 5, preferably an adhesive, on the top and bottom of the hollow block stones filled with the mineral fibers 4b, thereby preventing the mineral fibers 4b from accidentally falling out of the hollow block chambers 2.
  • the hollow blocks 1 treated in this way are again placed on the pallet 6 by the clamping frame 106, for example, so that they can have the design and position shown in FIG. 7.
