Definitions

  • the invention relates to a building block made of an expandable material, such as gas-pored concrete, with a jacket surrounding at least one vertical opening made of at least two transverse and two longitudinal walls, tongue and groove configurations being provided on the outwardly directed end faces of the transverse walls.
  • the invention is therefore based on the task of creating a stone that is easier and more convenient to move dry and thereby ensures good jointing with neighboring stones.
  • the above object is first achieved in that tongue-and-groove training is provided on the outwardly directed end faces of the transverse walls are that a symmetrical vertical groove is formed on one end face and a corresponding tongue is formed on the opposite end face and that the width of the tongue and groove and the width of the vertical opening essentially match.
  • the configuration according to the invention ensures that the longitudinal side walls retain their full strength over their entire length, that is to say they are not weakened by groove formations and nevertheless good grouting is achieved in which there are grooves and tongues in the region of the transverse side walls and only as far as the breakthroughs in the stone itself extend.
  • This configuration prevents the edges of the stones from breaking off on the one hand at the transition from longitudinal to transverse walls but also at the transition from tongue and groove to the end faces of the stones, which is a common danger in the known stones, as a result of which the stones function properly made of light material, such as gas porous concrete and therefore have their own thermal insulation effect, is impaired.
  • the transverse walls have on their upper side a recess which extends essentially across the width of the recess and which on the underside forms a recess by grinding the underside of the longitudinal walls Spring in the area of the transverse walls corresponds.
  • the tongue and groove designs also do not engage in the end faces of the longitudinal walls themselves, but are only provided in the area of the transverse webs or walls.
  • a large number of stones are cast in a common mold, the preferred embodiment being designed in such a way that the mold forms a flat pallet, a frame which surrounds and forms the outside of the individual stones and can be lifted off the pallet and separately from the frame has removable mold cores.
  • the mold cores are connected to one another in a grid-like manner via struts and that hold-down devices are provided for depressing the stones during demolding.
  • the demolding is then carried out in such a way that after these and a first solidification of the stones, the cores of the molds sitting inside the stones are raised, the stones being lifted by. Hold-down devices are pressed down, and then a common frame of the form surrounding the individual stones is lifted from a pallet on which the stones remain lying.
  • the spring on the underside of the stones is subsequently formed by wet-sanding the undersides of the longitudinal walls so that there is a web or a in the area of the transverse walls on the underside Tongue forms, which can engage in the groove already provided during casting and curing on the top of the webs or transverse walls.
  • the wet grinding offers the advantage that there is no dust and pollution for the environment and it is basically cleaner than dry machining. Grinding is possible because the material used for the gas porous concrete compared to light stones with wood fibers, etc. is quick and easy to sand, while known coarse material has to be milled.
  • the manufacture of the stone is therefore carried out according to the invention in such a way that when casting and hardening into the top of the stones, a groove is formed which is symmetrical to the longitudinal sides of the stones and that the longitudinal side walls of the stones are subsequently sanded in such a way on their underside that on the underside of the stones symmetrically to the longitudinal side walls remains a tongue corresponding to the groove, it being provided in particular that with the grinding of the underside of the side walls the side thereof is simultaneously sanded, so that the distance from the underside and top of the side walls to one predetermined measure is brought.
  • a device which is characterized in that a guide track is provided for the stones, which has two openings through which two grinding wheels protrude from below into the lower guide path of the stones, in particular above the Guideway at an adjustable distance two more grinding Disks are arranged that grip the top of the stones to be ground.
  • the method according to the invention and the device according to the invention form the possibility of grinding the top and bottom of the stones simultaneously, on the one hand producing such smoothness and flatness on the top of the stones, in particular their longitudinal walls, that the stones are stacked on top of one another sit firmly and evenly on top of each other, which facilitates dry movement, on the other hand, due to the simultaneous grinding of the top and bottom, a high dimensional stability of the stones in the order of 0.5 mm is achieved. This means that when the stones are moved dry, there are no problems due to excessive tolerances and inaccuracies of the stones themselves.
  • a preferred embodiment of the stones provides for use as formwork blocks.
  • the transverse walls have an arcuate recessed groove, which is offset on both sides via shoulders to the surfaces of the longitudinal walls, this groove in addition to the offset groove that is connected to the tongue on the Bottom edge of the stone interacts, is formed and serves that after pouring the pouring of the filling concrete, this can not only produce vertical but also horizontal connections between the stones.
  • the stone can basically have an opening with only end walls, according to a further embodiment it is provided that two individual openings are formed by a central transverse wall. In a further embodiment it is provided that the transverse walls are designed in such a way that the openings taper in a longitudinal section from top to bottom.
  • the block according to the invention can also be designed as a full block.
  • the walls are made of a light material, such as gas porous concrete, while it is provided that the openings are filled with concrete cores made of heavy or conventional lightweight concrete.
  • the core then forms the static framework and determines the strength of a wall made of stones according to the invention, while the walls made of gas-pored concrete are very warm insulating effect guaranteed.
  • This can be further increased by the cavities being at least partially filled with thermal insulation such as polystyrene or the like, it being provided in particular that the cavities are provided with thermal insulation on one side of a longitudinal wall and / or that the remaining cavity is made of concrete how heavy or light concrete is filled.
  • the stone according to the invention can thus also be used with an additional internal insulation, for example polystyrene, as formwork stone, the breakthrough in the core area which is left open by the additional thermal insulation being filled in place by concrete on site.
  • the stone with additional thermal insulation made of styrofoam can also be designed as a solid stone, in which case, as I said, the styrofoam insulation is preferably installed along a side wall, while the rest of the stone's place of manufacture is filled with concrete that hardens. This ensures that the heavy concrete in the shell of the gas porous concrete is still three-sided in connection with this, which would not be guaranteed, for example, with a fully rotating polystyrene insulation. Such a stone would not be stable in itself.
