Description

Die Erfindung betrifft einen maßgenauen Mauerstein aus Porenbeton, vorzugsweise aus Gasbeton, insbesondere in Form eines sogenannten Planblocks für fast fugenlose Innen- und Außenwände jeder Art.The invention relates to a dimensionally accurate brick made of aerated concrete, preferably aerated concrete, in particular in the form of a so-called plan block for almost seamless interior and exterior walls of all kinds.

Derartige Planblocks werden mit glatten Wandungen oder mit Nut- und Federprofil hergestellt.Such plan blocks are manufactured with smooth walls or with tongue and groove profiles.

Aufgabe der Erfindung ist, einen Planblock mit verbesserten Eigenschaften bezüglich Wärmedämmung und Längsleitungsschalldämpfung zu schaffen, sowie insbesondere seine Handhabbarkeit beim Mauern zu vereinfachen.The object of the invention is to create a plan block with improved properties with regard to thermal insulation and longitudinal line sound attenuation, and in particular to simplify its manageability when building walls.

Diese Aufgabe wird durch die Merkmale des Hauptanspruchs gelöst. Vorteilhafte Ausbildungsformen der Erfindung werden in den Unteransprüchen gekennzeichnet. Anhand der Zeichnung wird die Erfindung beispielhaft näher erläutert. Es zeigen:

  • Fig. 1 eine Draufsicht auf einen Planblock,
  • Fig. 2 eine Frontansicht des Planblocks,
  • Fig. 3 einen Schnitt entlang der Linie 111-111 in Fig. 1,
  • Fig. 4 schematisch ein Fräswerkzeug,
  • Fig. 5 schematisch das Verfahren zur Herstellung von gleichzeitig mehreren Ausnehmungen und Nuten.
This object is solved by the features of the main claim. Advantageous forms of training of the invention are characterized in the subclaims. The invention is explained in more detail by way of example with reference to the drawing. Show it:
  • 1 is a plan view of a plan block,
  • 2 is a front view of the plan block,
  • 3 shows a section along the line 111-111 in FIG. 1,
  • 4 schematically shows a milling tool,
  • Fig. 5 schematically shows the process for producing several recesses and grooves simultaneously.

Der Planblock aus Gasbeton weist die Bodenfläche 1, die Seitenflächen 2, 3, die Frontflächen 4, 5 und die Oberseite 6 auf. Andere Raumformen sind auf dem Markt, bei denen die Erfindung ebenfalls verwirklicht werden kann. Beispielsweise hat der abgebildete Planblock Abmessungen von 25 x 25 x 62,5 cm. Ein solcher Block ist beim Mauern von Hand zu transportieren und zu positionieren. Er ist zwar nicht sehr schwer, dennoch aber wegen seiner Abmessungen unhandlich.The plane block made of gas concrete has the bottom surface 1, the side surfaces 2, 3, the front surfaces 4, 5 and the top side 6. Other forms of space are on the market in which the invention can also be implemented. For example, the plan block shown has dimensions of 25 x 25 x 62.5 cm. Such a block is to be transported and positioned by hand when laying walls. It is not very heavy, but it is bulky due to its dimensions.

Die Erfindung sieht vor, vorzugsweise in den Frontflächen 4, 5 Nuten 7 einzubringen, die mit ihrer Tiefenerstrekkung parallel z.B. zur Bodenfläche 1 bzw. Oberseite 6 in den Stein gehen und von der Seitenfläche 2 zur Seitenfläche 3 durchgehend verlaufen. Vorteilhaft ist, wenn die Nuten 7 - wie abgebildet - symmetrisch zur Achse 8 sich gegenüberliegend angeordnet sind. Nach einer besonderen Ausführungsform der Erfindung befinden sich die Nuten 7 kurz unterhalb der Oberseite 6, wobei im Bereich von der Oberseite 6 bis zur Nut 7 eine Freisparung bzw. Ausnehmung 9 vorgesehen ist, die weniger tief ist als die Nut 7. Die verbleibende Tiefe der Nut 7 ist so gewählt, daß sich eine ausreichend tiefe Griffkante 10 ergibt.The invention provides preferably to introduce grooves 7 in the front surfaces 4, 5, which with their depth extension parallel e.g. go to the bottom surface 1 or top 6 in the stone and run continuously from the side surface 2 to the side surface 3. It is advantageous if the grooves 7 - as shown - are arranged symmetrically to the axis 8 opposite one another. According to a special embodiment of the invention, the grooves 7 are located just below the top 6, a recess or recess 9 being provided in the area from the top 6 to the groove 7, which is less deep than the groove 7. The remaining depth of the Groove 7 is chosen so that there is a sufficiently deep grip edge 10.

Die Nut 7 ist.im Querschnitt vorzugsweise U-förmig, wobei - wie aus dem Beispiel ersichtlich - die bodenseitige Kante 11 länger ausgeführt ist als die Griffkante 10.The groove 7 is preferably U-shaped in cross-section, the bottom edge 11 being made longer than the grip edge 10, as can be seen from the example.

Eine bevorzugte Ausführungsform der Erfindung sieht vor, die Nut - wie abgebildet - in der Draufsicht (Fig. 1) bogenförmig verlaufend auszubilden. Dabei ist zweckmäßig auch die Aussparung 9 bogenförmig verlaufend zu gestalten und dabei lediglich ein geringerer Radius zu wählen, so daß die Überdeckung 12 gleichmäßig dick ist, wobei der Radius auf einer Senkrechten liegt, die auf die Mitte der Frontfläche 4, 5 stößt (nicht dargestellt).A preferred embodiment of the invention provides for the groove - as shown - to be curved in plan view (FIG. 1). It is also expedient to design the recess 9 in an arcuate manner and only to select a smaller radius, so that the overlap 12 is uniformly thick, the radius being on a perpendicular that meets the center of the front surface 4, 5 (not shown) ).

Die erfindungsgemäße Nut erleichtert die Handhabung des Planblocks ganz erheblich. Zunächst ist leicht erkennbar, wie und wo der Stein gefaßt und positioniert werden soll. Dabei kann sich die Nut an einer Stelle befinden, z.B. - wie abgebildet - im Bereich der Oberseite 6, die eine bestimmte Lage im Bauwerk einnehmen soll, so daß sich optimale Festigkeitsaufnahmen des Mauerwerks ergeben können (z.B. Lage bezüglich der Steinrichtung beim Gären der Masse usw.). Bei bisher bekannten Grifflöchern z.B. in Ziegeln oder Kalksandsteinen sind die Grifflöcher durchgehende, mittig angeordnete Löcher, die keine weitere Funktion leisten können. Vorteilhaft bei den erfindungsgemäßen bogenförmigen Nuten ist, daß die Hand leichtfühlig zur tiefsten Stelle der Nut geleitet wird, die sich in der Mitte M der Frontfläche 4, 5 (Fig. 2) befindet, so daß ein sicherer Griff möglich ist. Dabei ist ebenso wichtig, daß die Nut 7 durch die Aussparung 9 auch in der Draufsicht sichtbar ist.The groove according to the invention considerably facilitates the handling of the plan block. At first it is easy to see how and where the stone should be gripped and positioned. The groove can be located at one point, for example - as shown - in the area of the upper side 6, which is supposed to occupy a certain position in the building, so that optimal strength absorption of the masonry can result (eg position with regard to the direction of the stone when fermenting the mass, etc .). In the case of handle holes known hitherto, for example in bricks or sand-lime bricks, the handle holes are continuous, centrally arranged holes which can have no further function. An advantage of the arcuate grooves according to the invention is that the hand is gently guided to the deepest point of the groove, which is located in the middle M of the front surface 4, 5 (FIG. 2), so that a secure grip is possible. It is also important that the groove 7 is visible through the recess 9 in the top view.

Überraschend ist, daß durch die Nutausbildung die Festigkeit nicht gemindert wird und daß sowohl die Wärmedämmung als auch die Längsseitenschalldämpfung in Richtung Nut-Nut, also von Frontseite zu Frontseite besser wird, was noch nicht erklärbar ist.It is surprising that the strength is not reduced by the groove design and that both the thermal insulation and the longitudinal sound insulation in the direction of groove-groove, that is to say from front to front, is better, which cannot yet be explained.

Die erfindungsgemäße Nutanordnung ist auch für Planblöcke mit Nut- und Federprofilen auf den Frontflächen 4, 5 vorgesehen (nicht dargestellt). Dabei ist im Bereich des Federprofils ein Teil des Federprofils weggeschnitten. Im Bereich des Nutprofils ergibt sich, daß die Nut 7 zweckmäßigerweise tiefer ist als das Nutprofil selbst.The groove arrangement according to the invention is also provided for face blocks with tongue and groove profiles on the front surfaces 4, 5 (not shown). Part of the spring profile is cut away in the area of the spring profile. In the area of the groove profile, it follows that the groove 7 is expediently deeper than the groove profile itself.

Bei den oben angegebenen Abmessungen des Planblocks ist günstig, wenn die Höhe H1 der Aussparung 9 4 cm und die Höhe H2 der Nut 7 3 cm (Fig. 2) sowie die maximale Tiefe T2 der Nut 7,von der Frontfläche gerechnet, 3,5 cm und die maximale Tiefe T1 der Aussparung 9,von der Frontfläche gerechnet, 1,5 cm betragen. Bei anderen, von den angegebenen Abmessungen erheblich abweichenden Abmessungen des Planblocks,werden entsprechend andere Abmessungen für die Nut 7 vorgesehen.Given the dimensions of the plan block given above, it is advantageous if the height H 1 of the recess 9 4 cm and the height H 2 of the groove 7 3 cm (FIG. 2) and the maximum depth T 2 of the groove 7, calculated from the front surface, 3.5 cm and the maximum depth T 1 of the recess 9, calculated from the front surface, be 1.5 cm. In the case of other dimensions of the plan block that differ significantly from the dimensions specified, corresponding other dimensions are provided for the groove 7.

Nach einer besonderen Ausführungsform der Erfindung werden die Nuten 7 und die Ausnehmungen 9 ausgefräst, wenn die Gärung der wie üblich hergestellten Gasbetonmasse abgeschlossen, die Form geöffnet und die sich auf dem Gärboden befindliche Masse geschnitten ist. Mit einer Vielzahl von Fräsern, die auf einer Antriebswelle angeordnet sind, werden mehrere Nuten 7 und Ausnehmungen 9 gleichzeitig gefräst, wobei jedoch davon jeweils eine Nut und eine Ausnehmung in einem bereits geschnittenen Rohling eingebracht werden.According to a special embodiment of the invention, the grooves 7 and the recesses 9 are milled out when the fermentation of the gas concrete mass produced in the usual way is completed, the mold is opened and the mass located on the fermentation floor is cut. With a plurality of milling cutters, which are arranged on a drive shaft, a plurality of grooves 7 and recesses 9 are milled at the same time, but a groove and a recess are respectively made in an already cut blank.

Ein Fräswerkzeug ist in Fig. 4 schematisch abgebildet. Es besteht aus einem Rohr 13, auf dessen Mantel rechtwinklig zur Längsachse 14 abstehende Fräsbügel 15 befestigt sind, die radial nach außen abstehen. Die Form der Bügel 15 entspricht der Querschnittsform der Ausnehmung 9 plus Nut 7. Demgemäß ist die Form der Bügel zur Herstellung der in den Fig. 1 bis 3 abgebildeten Nut, wie aus Fig. 4 erkennbar, L-förmig. Das Rohr 13 wird um seine Längsachse 14 mit geeigneten Antriebsmitteln in Rotation versetzt und an den Rohling 16 herangefahren. Es beginnt danach das Ausfräsen, während das Rohr 13 weiter an den Rohling herangefahren wird, bis die gewünschte Tiefe der Nut 7 und Ausnehmung 9 erreicht ist. Dann wird das Rohr 13 wieder zurückgefahren.A milling tool is shown schematically in FIG. 4. It consists of a tube 13, on the jacket of which are attached at right angles to the longitudinal axis 14, milling bows 15 which protrude radially outwards. The shape of the bracket 15 corresponds to the cross-sectional shape of the recess 9 plus groove 7. Accordingly, the shape of the bracket for producing the groove shown in FIGS. 1 to 3, as can be seen from FIG. 4, is L-shaped. The tube 13 is rotated about its longitudinal axis 14 with suitable drive means and moved to the blank 16. The milling then begins while the tube 13 is moved further towards the blank until the desired depth of the groove 7 and recess 9 is reached. Then the tube 13 is moved back again.

Vorteilhaft ist, auf einem langen Rohr mehrere Bügel 15 hintereinander fluchtend oder zweckmäßigerweise hintereinander und seitlich am Umfang versetzt (nicht dargestellt) vorzusehen sowie mehrere Rohre davon übereinander auf Abstand anzuordnen und mit einem einzigen Antrieb zu versehen. Man kann damit eine ganze Wagenladung aufeinmal bearbeiten. Eine solche Verfahrensweise ist in Fig. 5 angedeutet. Gezeigt wird der Härteboden 17, der sich auf einem nicht dargestellten Kesselwagen befindet. Auf dem Härteboden 17 lagern die bereits geschnittenen Planblöcke 16, in die die Nuten 7 mit Ausnehmungen 9 eingefräst werden sollen. Dabei befinden sich die Frontflächen 4 und 5 an den Längsseiten des Härtebodens 17. Mehrere Rohre 13 sind übereinander auf Abstand angeordnet und tragen jeweils hintereinander Bügel 15, so daß gleichzeitig mehrere Ausnehmungen 9 und Nuten 7 eingefräst werden können. Die Rohre 13 stehen mit einem einzigen Antrieb in Verbindung (nicht dargestellt).It is advantageous to provide several brackets 15 in line or expediently one behind the other and laterally offset on the circumference (not shown) on a long tube and to arrange a plurality of tubes at a distance from one another and to provide them with a single drive. You can use it to process an entire truckload at once. Such a procedure is indicated in FIG. 5. Shown is the hardness floor 17, which is located on a tank car, not shown. The already cut plan blocks 16, in which the grooves 7 with recesses 9 are to be milled, are stored on the hardness base 17. The front surfaces 4 and 5 are located on the long sides of the hardening base 17. A plurality of tubes 13 are arranged one above the other at a distance and each carry brackets 15 one behind the other, so that a plurality of recesses 9 and grooves 7 can be milled. The tubes 13 are connected to a single drive (not shown).
