The The invention relates to a insulated Bottom plate for Basement, single and multi-storey buildings, consisting of the foundation upholstery Foam glass ballast, supply and disposal lines, insulation, castable Building materials and a pipe network according to the description of claims 1-4.

By the constantly increasing needs higher and higher insulated building and the required and associated energy savings It is the task to develop a base plate, which with low Expenses contributes the energy efficiency of buildings positively influence. A floor plate can after its completion a building never again be insulated with little effort.

ever the lower the U value, the less energy is needed around for a to contribute to comfortable living.

With this combination of materials, foam glass gravel and chippings with polystyrene or neopar is guaranteed the required Thermal insulation requirements more economical and efficient than before. In the Practice showed it with the use of ever thicker insulating materials and the necessary load-bearing additional insulations the economic and financial factor is almost impossible to catch. For load-bearing areas in prefabricated and solid construction was a limit for the use of insulation materials in the foundation area set.

The Invention relates to a successful combination of foam glass ballast and Styrofoam in use of the floor slab for basement, single and multi-storey buildings in solid and prefabricated construction is thus more economical than previous versions.

Insulated floor slabs are already known from the DE 198 01 123 A1 . DE 102 06 782 A1 such as DE 202 02 481 U1 and DE 202 02 480 U1 which produce prefabricated polystyrene elements or various other polystyrene combinations thermal bridge-free constructions for floor panels. Polystyrene has become increasingly costly in recent years due to the rising world market prices of the raw material crude oil. This use of polystyrene, which is becoming ever more expensive, is reduced to an economically acceptable level or even halved with this combination with foam glass.

Foam glass gravel is a material which is made from recycled waste glass. This material is capillary breaking and thus enables use of polystyrene as a replacement for the expensive perimeter insulation in the area of edge insulation, since no direct contact here comes with the soil.

Farther has foam glass ballast good thermal insulation properties, so the installation of foam glass gravel at the same time the frost protection replaced under the bottom plate and thus it is no longer necessary is to introduce strip foundations.

Also the expensive perimeter insulation falls in the load-bearing Range away, since foam glass in the compacted state load-bearing is.

The terrain for the bottom plate to be created is measured and staked as usual according to the required dimensions of the bottom plate. By accurately making the Erdausschachtung for the bottom plate or by terrain caused a formwork foundation for the introduction of the foam glass ballast is created. The supply and disposal lines are in the soil or foam glass ballast in a gravel bed laid. The foam glass ballast is distributed and compacted in the entire area. The areal compaction must be 1.3: 1 in the living area. In the load-bearing area under the future walls, the seal ratio must be 2: 1, so that the load transfer for 380 kN / m ^{2 is} achieved. In the non-load-bearing area, a 2-5 cm thick layer of gravel for compensatory stabilization for the insulation made of polystyrene or Neopor is applied by pulling off the surface horizontally. Then the insulating body is placed as a plate. In the outer delimiting edge region of the bottom plate, a shuttering made of insulating bodies, plates or formwork elements is set up properly and connected free of thermal bridges. The introduction of the structural reinforcement depending on the static calculations takes place in the load-bearing area. In the non-load-bearing area, a constructive reinforcement is laid according to dimensions as a tension compensation. An appropriate laying of the pipe networks of metal, non-ferrous metal or plastic is installed. Subsequent concreting with sanding or felting of the concrete surface creates a screedless floor

The Advantages of this invention relates to manufacturing in the effective Combination of foam glass gravel and Styrofoam. The associated more economical Creation of an increased insulated floor slab is with big ones Savings in material and time associated. The insulation in the bottom plate is at least halved due to this combination or even further lowered. Depending on the requirements for heat protection is thus the desired to achieve low U-value in the bottom plate.
