Definitions

  • the invention relates to a method for manufacturing of a building block made of concrete.
  • a generic method for producing a Building blocks is known from FR 1 521 840 A.
  • FR 1 521 840 A there is intended to be a building block made of lightweight concrete and Produce heavy concrete, the lightweight concrete in essentially forms the core of the module and the Heavy concrete arranged on a side wall of the block is.
  • One opposite the heavy concrete Sidewall of the building block can be made of wood, making it easy to integrate cable channels is possible.
  • the block is in a 90 ° tilted position, regarding its later use, manufactured.
  • a layer is made first Heavy concrete filled into a mold, then the later core of the lightweight concrete block backfilled and finally the wooden side wall on the lightweight concrete applied.
  • Building blocks are also known from practice Concrete that must meet high dimensional accuracy and are generally mechanically reworked. This is especially true for plan stones and dry too moving formwork or blocks.
  • the mechanical Post-processing can be done, for example, by Milling done.
  • a disadvantage of lightweight concrete is that Lightweight concrete in the processed state in the building has lower strength and hardness, e.g. normal concrete or heavy concrete. Even the low weight can e.g. disadvantageous with regard to sound insulation his.
  • the height of the shape must match the height of the finished building block protrude because the poured concrete before shaking or the compression by the stamp a larger one Volume.
  • the shape must therefore be dimensioned in this way be that they also provide the necessary amount of concrete the vibration and compression with the stamp can.
  • DE 810 185 For further prior art reference is made to DE 810 185 and referred to DE 801 854.
  • the present invention is based on the object a method for producing a building block from concrete to create, through which to manufacture the building block inexpensively has a high hardness and strength and can be reworked inexpensively.
  • the building block made of concrete with different Bulk densities and, as a result, with different ones Properties is formed, the each advantageous features of the different types of concrete be used accordingly.
  • the building block receives concrete with a high bulk density high hardness, strength and weight.
  • concrete with a high bulk density e.g. normal or heavy concrete, cheaper than using concrete a lower bulk density, e.g. Lightweight concrete.
  • the second Concrete with the lower bulk density after vibrating of the first concrete filled with the higher bulk density becomes.
  • the bulk density settles and it is created a corresponding free space.
  • the second concrete with the lower bulk density is no problem be filled in.
  • the block By arranging the concrete with the lower one Bulk density on an upper and / or lower side of the block the block can be especially on these pages easy to edit.
  • Use of lightweight concrete in Area of the top and / or bottom of the block has proven to be particularly advantageous in terms of mechanical Machining, e.g. by milling.
  • the block can be on the top and / or bottom easily with conventional Work means while its core by the Concrete with a higher bulk density is a corresponding one Has hardness, strength and weight.
  • the building block receives a special density high hardness, strength and weight. Reduce also necessary for the production of the module Material costs because concrete has a higher bulk density is significantly cheaper than concrete with a lower bulk density.
  • Building block 1 shows a building block 1 for the construction of buildings.
  • Building block 1 consists of a first concrete 2 with a high bulk density and a second concrete 3 with a lower bulk density.
  • the outer walls of the block 1 are from an upper side 4, an underside 5 and side walls 6 are formed. There is the top 4 of the block 1 from the concrete 3 with the lower bulk density. The Bottom 5 and the side walls 6 consist of the Concrete 2 with the high bulk density.
  • top 4 of the concrete 3 with the lower bulk density e.g. Light concrete
  • conventional carbide tools machined e.g. milled
  • module 1 can be made from a concrete 3 existing with a lower bulk density Layer has a thickness of about 10 mm. Thereby it is possible that block 1 is at least 90% consists of the concrete 2 with the higher bulk density.
  • the Module 1 thus has a very high strength and Hardness. Due to the high percentage of concrete 2 leave with the appropriate strength and hardness Realize thin outer walls with module 1.
  • Module 1 can be used as any module for creation of buildings, especially as formwork or block stone.
  • the building block 1 can also be used with insulation (not shown), like for example with formwork blocks is common to be provided.
  • the second concrete 3 with the lower bulk density e.g. Light concrete, filled.
  • the concrete 3 is also shaken through the vibrators 8.
  • 5 shows a compression of the two concrete layers 2, 3 by a stamp 10 or a pressing device. This will make the two layers of concrete 2, 3 compressed in their final stage and thus correspond the dimensions of the finished one shown in FIG Module 1.
  • the result of the joint compression a heavy-duty connection between the two Concrete layers.
  • the filling of the concrete 3 takes place on the still moist Concrete 2. This ensures that a solid and stable connection between the concrete 2 and the Concrete 3 is created.
  • the concrete 3 can be used the lower bulk density on both the top 4 as well as on the underside 5 or the side walls 6 of the block 1 are applied.
  • the concrete 2 can have a quartz portion to increase the strength and hardness. As an alternative or in addition to this, the concrete 2 can also have a proportion of gravel.
  • the concrete 3 with the low bulk density can have a maximum weight of 1400 kg / m 3 , for example.
