Definitions

  • the invention relates to a brick, in particular in the form of a so-called plan block for almost seamless interior and exterior walls of any kind, and a method for its production and an apparatus for performing the method.
  • a brick of the type specified in the preamble of claim 1 is described and shown in DE-U-7 317 165.
  • a hollow block is provided with grip pockets on the end faces, which are cuboid in shape with grip surfaces extending upwards outwards and counter surfaces sloping downwards outwards.
  • Handle bags in this configuration are not only insufficient for ergonomic reasons because there is no easy-to-use shape, but they are also difficult to manufacture, e.g. B. by molding, whereby an expensive design and manufacture is specified.
  • a milling machine for milling the upper or lower side of a gas concrete strand extending parallel to the driving direction with a self-supporting, still semi-plastic consistency is known, the milling machine consisting of a tubular axis, around the lateral surface of which a number of strips is attached, which carry U-shaped, stiff profiled milling wires.
  • the invention has for its object to develop a brick made of aerated concrete, in particular gas concrete, a method for producing the brick and / or a device for performing the method so that a handle groove with a particularly large grip area can be created on the brick, in particular, the positionability.
  • gripping surfaces can therefore be created, because gripping surfaces extending beyond them can be created on both sides of the cutouts. This significantly improves handling because, on the one hand, larger gripping surfaces are available and, on the other hand, it can be fitted into the grip pockets more easily and easily.
  • the grip grooves according to the invention can be machined in a simple manner by milling, which creates the possibility of attaching them to aerated concrete, in particular gas concrete, and thereby achieving low manufacturing costs.
  • the handle groove and the recess are simultaneously milled out in a circular arc when the fermentation of the conventionally produced aerated concrete mass is complete, the mold is opened and the mass is cut into rectangular brick blanks.
  • This method enables the handle groove to be worked in quickly and easily, which simplifies production and reduces production costs.
  • the further developments according to claim 7 and / or 8 also contribute to this.
  • the device according to the invention according to claim 9 for carrying out the method is of a simple and inexpensive construction, and it is particularly suitable for milling out grip grooves according to the invention.
  • the brick is a so-called plane block made of gas concrete with the bottom surface 1, side surfaces 2, 3, end surfaces 4, 5 and the surface 6.
  • Other shapes are on the market, in which the invention can also be implemented.
  • the plan block shown has dimensions of 25 x 25 x 62.5 cm. Such a plan block is to be transported and positioned by hand when laying the walls. It is not very heavy, but it is bulky due to its dimensions.
  • the invention provides for the introduction of special grip grooves 7 in the end faces 4, 5, the depth of which extends parallel, ie continuously, in the stone parallel to the bottom face 1 or surface 6 and can run from the side face 2 to the side face 3. It is advantageous if the grip grooves 7, as shown, are arranged symmetrically to the axis 8 opposite one another.
  • the grip grooves 7 are located just below the surface 6, a space or recess 9 being provided in the area from the surface 6 to the grip groove 7, which is less deep than the grip groove 7.
  • the remaining depth of the grip groove 7 is chosen in this way that there is a sufficient deep gripping surface 10.
  • the grip groove 7 has a cross section with preferably mutually parallel flanks (surfaces 10, 11), wherein, as can be seen from the exemplary embodiment, the bottom surface 11 - seen in cross section - is longer than the grip surface 10.
  • the grip groove 7 and the recess 9 run as shown in the plan view (FIG. 1) - in the shape of a circular arc. In this case, only a radius which is smaller in comparison with the radius of the groove depth is to be selected for the recess 9, so that the overlap 12 is uniform, the radii being perpendicular to a perpendicular which lies in the vertical central plane of the brick (not shown).
  • the grip groove 7 makes the handling of the plan block considerably easier. At first it is easy to see how and where the brick should be gripped and positioned.
  • the grip groove 7 is located at a point at which the recess 9 - as shown - runs out in the area of the surface 6, which is to assume a specific position in the building, so that optimum strength absorption of the masonry can result (e.g. position regarding the direction of the stone when fermenting the mass, etc.).
  • An advantage of the arcuate grip grooves according to the invention is that the hand is gently guided to the deepest point of the grip groove 7, which is located in the center M of the end face 4, 5 (FIG. 2), so that a secure grip is possible.
  • the handle groove 7 is visible through the recess 9 in the top view. It is surprising that the strength of the grip groove does not reduce the strength, and that both the thermal insulation and the longitudinal sound insulation in the direction of the grip groove 7 - grip groove 7, that is to say from face to face, is better, which cannot yet be explained.
  • the grip groove arrangement according to the invention is also provided for face blocks with tongue and groove profiles on the end faces 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 grip groove 7 is expediently deeper than the groove profile itself.
  • the grip groove 7 In the case of other dimensions of the plan block that deviate significantly from the specified dimensions, correspondingly different dimensions are provided for the grip groove 7.
  • the grip 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.
  • a plurality of cutters which are arranged on a drive shaft, a plurality of grip grooves 7 and recesses are milled at the same time, but a grip groove 7 and a recess 9 are respectively introduced into an already cut blank.
  • a milling tool is shown schematically in FIG. 4. It consists of a tube 13, on the jacket of which is attached at right angles to the longitudinal axis 14, milling wire stirrups 15 which protrude radially outwards.
  • the shape of the milling wire bracket 15 corresponds to the cross-sectional shape of the recess 9 and the handle groove 7. Accordingly, the shape of the milling wire bracket 15 for producing the handle groove 7 shown in FIGS. 1 to 3, as can be seen from FIG. 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 16 until the desired depth of the grip groove 7 and recess 9 is reached. Then the tube 13 is moved back again.
  • FIG. 5 Shown is the hardness floor 17, which is located on a tank car, not shown.
  • the already cut blanks 16, into which the grip grooves 7 with recesses 9 are to be milled, are stored on the hardness base 17.
  • the end faces 4 and 5 are located on the long sides of the hardness floor 17.
  • a plurality of tubes 13 are arranged horizontally one above the other at a distance and in each case carry milling wire stirrups 15 one behind the other, so that a plurality of recesses 9 and grip grooves 7 can be milled in at the same time.
  • the tubes 13 are connected to a single drive (not shown).
