Definitions
- the invention relates to a perforated light brick according to the Preamble of claims 1 and 3.
- Such bricks become Execution of brick masonry mainly in residential construction used, conventionally bricked or as a facing brick walled up with thin-bed mortar.
- the holes form above and below open continuous vertical channels.
- the invention has for its object a lightweight brick to propose one with sufficient static strength significantly better thermal insulation behavior than known ones
- Light brick has, in particular, a coefficient of thermal conductivity ⁇ ⁇ 0.15 [W / m ⁇ K] and at the same time has a good airborne sound absorption capacity (Sound rigidity) with no tendency to Sound line has.
- Hole cross sections are in the form of regular hexagons particularly suitable. This is given in the honeycomb Structure can be used in the new dimensioning for bricks extreme use of thin bars.
- the compressive strength of a brick with filigree hexagon honeycomb perforation is the same Brick bulk density at least 25% higher than that of known ones Bricks with the usual hole patterns.
- the honeycomb pattern itself can be with respect to the longitudinal direction of the brick be arbitrarily oriented.
- the pattern is preferred however lay so that the heat path in the transverse direction of the brick becomes as long as possible and that is the case when webs are vertical run to the visible surfaces of the brick or two opposite corners of the hexagons to the visible surfaces are facing.
- the heat path extension is then around 16% compared to the arrangement with the visible surfaces parallel webs.
- the body density can be reduced by porosity (Fig. 10).
- porosity Fig. 10
- low thermal conductivity values are achieved even with weak porosity
- filigree structures allow relatively high porosity without significantly reducing the compressive strength.
- the porosity should not be so extreme that it reduces the compressive strength too much.
- the use of a fibrous porosity agent is provided.
- the use of paper fibers is particularly advantageous.
- good ductility of the moist clay strand is important, which can be achieved by enriching the brick clay with a proportion of about 5 to 25% fat clay.
- Fat clay is a high quality clay with a high Al 2 O 3 content. In this way, in addition to the structurally favorable perforation pattern, the strength of the brick is positively influenced despite the large number of perforations.
- the butt joint area is in known brick shapes because of the large material accumulations at this point always technically problematic. This is especially true for heat-optimized slot-hole bricks because of a thick Brick outer layer the structurally weak inner area must be balanced. In contrast, the proposed filigree small hole structure so stable, and in Cross direction not weakened that the butt side with a relatively thin outer layer can be provided.
- each butt joint at least one tongue and one groove arranged to match be.
- one of the two abutting surfaces of a brick a spring protruding beyond the projections is provided, which is provided in one of the anyway Wells of the adjacent tile fits.
- one spring per brick is preferable because of the Brick then, after extrusion, on the if desired other impact surface can be stored. To light the feather to be able to insert into the corresponding specialization suggested this recess a little wider than the rest To make recesses and the laterally adjacent holes accordingly easy to deform.
- the brick inhibits the longitudinal sound conduction and is therefore particularly suitable for external walls.
- values of less than 0.4 kg / dm 3 are within the possible range.
- the brick is therefore extremely light and little clay material and, accordingly, little energy, in particular when firing, is required for its production. The low weight is advantageous when processing and transporting. Lower energy tonnage saves more energy.
- the previously unattainable low wall weight enables the use of the bricks, for example, for partitions on unsupported ceilings, where bricks could not previously be used.
- the bricks When used as a load-bearing inner wall, in addition to preventing longitudinal sound conduction, sound insulation in the passage direction that is significantly better than known bricks due to the low natural vibration with the same mass must also be noted.
- the proposed bricks can be separated better in the transverse direction, which leads to lower losses due to brick smashing in practical construction work.
- FIG. 1 are two bricks 1 and 2 with their butt sides to each other. There is a special groove 3 on brick 1 and one Spring 4 shown on brick 2.
- the brick 2 is a partial enlargement of the brick shown completely in Fig. 2.
- the spring 4 is only once on an abutment surface of the brick available.
- One side wall (visible side) of the brick is 5 designated. This also indicates the longitudinal direction of the bricks.
- the bricks have a hexagonal honeycomb pattern, whereby the hexagons are arranged so that two each other opposite corners to the side walls 5 show and a Part of the webs 6 is perpendicular to the side walls.
- the thickness of the webs in this is preferred Embodiment slightly more than 2 mm.
- the hole percentage at this honeycomb pattern is 66.5%.
- On the side walls 5 are the hexagon holes slightly blunted.
- the walls 7 of the bricks on the butt sides follow the Outer wall sections of those hexagon holes that the last, transverse row of holes in each tile form. This creates projections 8 and depressions 9.
- the thickness of the walls 7 changes between about 3 and 5.5 mm is therefore less than three times the web thickness.
- the Spring 4 protrudes over the projections 8. You see from that Area of this single tongue 4 and the associated groove 3 once off, so are the impact walls 7 of the two bricks designed mirror-symmetrical to each other.
- the one another corresponding projections 8 lie against each other.
- the one another corresponding recesses 9 form both bricks with each other a hexagonal cavity 10.
- the abutting sides of the two bricks experience irregularities only in the area of tongue and groove, which is close to a Side wall 5 are arranged.
- the groove 3 is somewhat stronger expanded than the other depressions 9.
- the spring 4 contains a cavity 11 in the form of a partial cut hexagons.
- the cavities 10 and 11 act from a certain distance looks about like the other hexagon holes, so that the Joint area continues the honeycomb structure and thereby has an almost undiminished thermal insulation effect.
- the brick shown completely in Fig. 2 has 21 rows of holes.
- the hole row spacing a is approximately 14 mm.
- the only wedge-shaped spring 4 fits an identical neighboring tile in one of the three arranged near the side walls 5 Grooves 3, 12, 13.
- the brick shown is 248 mm long and 300 mm wide (Thickness of the brick wall).
- the clear width of the honeycomb (perpendicular to the webs) is 14 mm.
- the thickness of the Side walls 5 is 7 mm and the thickness of the walls 7 in Direction of impact measured 5.5 mm.
- the two faces are in the formed essentially mirror-symmetrical to each other.
- you can also use this hole pattern Brick for thicker or thinner walls according to the national standards are designed, which is why correspondingly more or less longitudinal rows of holes are to be provided.
- the brick density class 0.5 kg / dm 3 is achieved with this brick.
- the unit weight is reduced from 13.5 kg to 9 kg.
- the same static pressure resistance is nevertheless achieved.
- the airborne sound absorption capacity in all spatial directions is superior to that of all previously known perforations.
- the bricks with a round hole pattern according to FIG. 3 show that same principle of the training of the face as well Projections 8 'and depressions 9' are formed as they are in the case of a cut from the Hole pattern result.
- the protrusions have flat sections, the depressions are circular.
- the hole shape of the example according to FIG. 4 is an in Brick corner shortened corner. Are here too Projections 8 ", depressions 9" and a spring 4 " distinguish, which are similar in shape to the holes.
