  • the object of the invention is to avoid these disadvantages and to provide a base that is simple and inexpensive to manufacture, the terrain level can be at the middle level of the base and the actual wooden wall is built on the base.
  • a base with the features of claim 1.
  • the invention further relates to a wooden wall according to claim 22 with a such a base and a building according to claim 26 with at least one such wooden wall.
  • the construction material for the frame of the base can be combined with all commercially available sealing materials.
  • the thermal conductivity of the construction material of the struts of the frame is favorably preferably between 0.070 and 0.090 W / (mk).
  • the compressive strength of this construction material of the struts is preferably about 1.8 MPa, preferably in any case more than 1.5 MPa.
  • rod-shaped or cuboid-shaped struts can now preferably be connected to a stable frame, for example by a screw connection.
  • the frame now has recesses between the struts, into which the dimensionally stable filler elements made of thermal insulation material are inserted and connected to the struts of the frame.
  • These dimensionally stable filling elements are preferably made of recycled, thermally processed glass (foam glass).

  • the dimensionally stable filling elements can also be perforated for any built-in components and passages and, for example, have openings or indentations at the edge. In general, however, they are properly inserted into the recesses. In this way, thermal bridges through the base can be avoided.
  • the dimensionally stable filling elements contribute overall to the stability of the base, since they support the struts of the frame on the inner walls of the struts of the frame that face the recesses. Similar considerations apply to the materials of the dimensionally stable filling elements as to the struts of the frame. They are favorably insensitive to moisture, highly resilient and easy to process, so that they can be easily integrated into the production process of timber wall constructions.
  • the base consisting of superposed, dimensionally stable filling elements is overall insensitive to moisture and is durable.
