Definitions

  • the invention relates to a building block made of concrete, in particular Formwork or block stone, for creation of buildings.
  • the invention also relates to a method for the production of a building block made of concrete.
  • building blocks that consist of Concrete can be made. Building blocks that are high Dimensional accuracy must be met in general mechanically reworked. This applies in particular to Plan stones and formwork or Blocks.
  • the mechanical post-processing can for example by milling.
  • 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 be.
  • Processes for producing are known from practice to date of a building block made of concrete, in which a shape is filled with concrete. After pouring the concrete into the form, with the filling for example be carried out via a filler neck or trolley can, the shape is arranged accordingly Vibrators shaken. By shaking the mold sets the concrete comes off and is thereby compacted. In addition is used to shake the mold a corresponding stamp or a pressing device achieved further compaction of the concrete.
  • 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 compaction with the stamp can.
  • the present invention is based on the object a building block and a method for producing a To create building blocks from concrete, through which the building block is inexpensive to manufacture, high hardness and Has strength and reworked inexpensively can be.
  • This object is achieved in that using the building block made from at least two types of concrete different bulk densities is formed, the Concrete with the lower bulk density at least arranged to be machined outside of the block is.
  • the building block made of concrete with different 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 block is at least closed 90% consists of the concrete with the higher bulk density.
  • 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.
  • An inventive method for producing the Building blocks made of concrete, in particular a formwork or Blockstein, for the construction of buildings, whereby the concrete is filled into a mold, shaken and compacted is that at least in the form two types of concrete with different bulk densities be poured, the concrete with the lower Gross density at least on one to be processed Outside of the block is introduced.
  • the second concrete with the lower bulk density after the Shaking the first concrete with the higher bulk density is replenished.
  • 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 To ensure the required accuracy of the module 1 can be achieved by appropriate post-processing it is generally sufficient if 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. Of 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.
  • Building block 1 can be used as any building block of buildings, in particular also 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 Layers of concrete.
  • 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 formed.
  • the concrete 3 with the lower bulk density on both the top 4 as well as on the bottom 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, for example, have a maximum weight of 1400 kg / m 3 .
