Definitions

  • thermal insulation made of local foam or silicate foam or polyurethane foam not only significantly inhibited heat transfer, but also increased sound insulation and even met the requirements of fire resistance class F-120.
  • the inhibition of the heat transfer could be increased even more if the cavities were shifted axially relative to one another, so that the spaces between the individual cavities did not form cold bridges. Only where the stones were interlocked with one another or with an intermediate layer of mortar or other binding agents did cold bridges inevitably arise, via which the heat could escape.
  • DE-OS 24 40 466 describes a hollow block with a longitudinally axially oriented insulation layer insert, which form tongue and groove both on the butt sides and on the contact sides.
  • This invention was undoubtedly effective, but not suitable for practical use, as the outstanding, structurally weak parts of the thermoplastic material were largely broken off during transport.
  • the proposals cer DE-OS 19 53 354 and 24 22 236 are not much more realistic.
  • the stone is provided with several longitudinal rows of cavities, which have different diameters and are axially displaced relative to one another.
  • the inventor endeavors to inhibit the heat transfer on the abutting sides by means of vertical slots into which the bricklayer is supposed to insert heat-insulating materials during the brickwork. This latter idea is far from practical because it is far too labor-intensive.
  • a hollow block, from which thermal insulation material - usually foam - protrudes unprotected over the stone level, is, as already mentioned, unusable in practice. Building blocks must be able to endure rough transport and rough treatment by the bricklayer; with appropriate careful handling of the stones, the labor-intensive construction work would be even more complex, to the point of unbearable.
  • the insulation fillings of the cavities may only extend to the levels of the contact surfaces or to the abutting surfaces of the stone. Under this condition, which is indispensable for practical use, it has so far not been possible to create effective thermal insulation in the areas particularly exposed as cold bridges around the tongue-and-groove toothing and around the contact surfaces.
  • the contact surfaces are particularly critical, as mortar is usually a better heat conductor than the stone itself.
  • the object of the invention is to eliminate this problem and to ensure effective thermal insulation in the areas mentioned.
  • this task of the invention is solved with the solvents set out in the protection claims.
  • the advantages achieved by the invention compared to the known state of the art are obvious: for the first time a hollow block has been created, on which the previously critical areas around the tongue and groove toothing and the contact surfaces have been provided with effective thermal insulation, without weakening the stone. These advantages have been achieved with an undemanding and robust design of the stone. Compared to the prior art, the hollow block according to the invention achieves an improvement in the thermal resistance by approx. 35%.
  • the hollow block in FIGS. 1 and 2 has two narrower springs 1, 2, a central broad spring 3 and two grooves 4, 5 on one end. On the other end of the joint, two tongues 6, 7, a wider central groove 8 and two half-grooves 9, 10 are formed.
  • a longitudinal web 11 which extends from the outer edge of the central tongue 3 to the bottom plane of the central groove 8.
  • a longitudinal groove 12 corresponding to the profile of the web is formed on the lower contact surface of the hollow block.
  • the hollow block has three rows of cavities, three broad cavities 13, 14, 15 in the middle and two somewhat narrower cavities 16 to 19 on each side.
  • the rows of cavities run parallel to the longitudinal axis of the hollow block and extend from the upper to the lower contact surface , see. Figure 2, 5,6,7.
  • the cavities 13, 14, 15 are connected to one another, cf. Figures 2 and 6.
  • FIG. 8 shows in section the interlocking of two hollow block bricks, namely “cold” bricked, that is, without mortar between the abutting surfaces.
  • the dashed lines 20, 21 show that heat transfer at the abutting surfaces is effectively inhibited by the thermal insulation fillings of the cavities 13, 17, 18 on both sides via the tongue and groove joints 3.8; 4.6; 5.7 protrude.
  • thermal insulation on the bearing surfaces is shown in FIG. 9.
  • two hollow blocks are connected to one another by means of a mortar layer 22.
  • the arrow on the right schematically represents a heat beam that penetrates the stone structure through the mortar layer (and of course on both sides of the mortar layer). As the two curved arrows in the center of the picture show, this heat ray is rejected and bent at the thermal insulation of the cavity 13.
  • the mortar layer generally forms a cold bridge because it usually conducts heat better than the stone.
  • Attempts to increase the thermal conductivity of the mortar by adapting the raw weight of the mortar material to the raw weight of the stone have brought improvements, but have not been able to remove the cold bridges formed on the mortar joints. It was only the present invention that made extensive thermal insulation at the mortar joints possible.
  • FIG. 10 shows an interesting variant of the thermal insulation according to FIG. 9.
  • mortar (or other binding agents) 22 are applied only to the edges of the support sides, to the flanks of the web 11, with the result that the flanks of the web 11 bear directly against the side walls of the longitudinal groove 12 of the hollow block lying directly thereon.
  • the thermal insulation area of the cavity 13 is thereby shifted further upwards and the heat barrier effect is increased accordingly.
  • the dashed box 23 shows the restricted area around the mortar joint 22.
  • the hollow block of the design example consists of pumice concrete with a bulk density of 0.80 kg / dm 3 .
  • the hollow block according to the invention can be made from any common material, such as gas concrete or the like.
  • the cavities are filled with a plastic foam (material density 0.015 kg / dm 3 ).
  • the bathleitzah _ the Bimsbetons is and that of the filling foam
