Definitions

  • the invention relates to a prefabricated structural element, a floor structure, and a method for making a floor structure according to the appended independent claims.
  • Cast floor structures comprise a thermal insulation material layer and a casting layer of a concrete mixture provided on top of it.
  • the casting layer for a floor structure is made at the construction site. Layers of fresh concrete are typically thick and therefore require a long drying time.
  • An object of the present invention is to reduce or even eliminate the above-mentioned problems present in prior art.

  • the object of the invention is to provide a prefabricated structural element and a floor structure which can be used in ground-based floors, flooring structures, pile-supported floor slabs, as well as inverted ceiling structures.
  • the prefabricated structural element, floor structure, and method for producing a floor structure according to the invention are primarily characterized in what will be presented in the characterizing parts of the independent claims.
  • the other, dependent claims will present some preferred embodiments of the invention.
  • Advantages of the invention are related to the prefabricated structural element, floor structure, and method for manufacturing the floor structure, even if this were not always mentioned separately.

  • the second casting compound layer to be formed at the building site and having a higher compression strength and/or hardness is considerably thinner than the first casting compound layer ready in the prefabricated structural elements. Therefore, the floor structure can be made quickly, and long drying times are no longer required at the building site, but the first casting compound layer requiring a longer drying time is already provided in the prefabricated structural elements.
  • the different properties of the casting compound layers guarantee sufficient strength and quick drying of the structure.

  • supporting bars are arranged in all the grooves on the surface of the thermal insulation material.
  • the spacing between the grooves on the planar surface of the insulation material board may vary; typically, the spacing between grooves may be about 50 to 600 mm.
  • the spacing between the grooves may be different in the width direction and the length direction of the board.
  • grooves are arranged at intervals of about 300 mm (measured center-to-center) in the length and width directions of the structural element; this is an advantageous solution to provide sufficient strength when supporting bars are provided in all the grooves.

  • the supporting bars extending beyond the side surface of the structural element make it possible to fasten the structural elements to each other in the floor structure and simultaneously secure the strength of the floor made of prefabricated structural elements throughout the area of the floor structure, including the joints of the structural elements.
  • the insulation material layer is formed of several boards of thermal insulation material
  • the supporting bars may be arranged in the grooves to partly overlap at the joints of the boards of thermal insulation material, to make a strong structure. These joints will be embedded in the first casting compound layer.
  • the supporting bars used in the invention may be any supporting bars suitable for the purpose.
  • the supporting bars are ribbed reinforcement bars, prefabricated meshes made of ribbed bars, or other conventional products used for reinforcement.
  • the supporting bars are supporting bars comprising glass fibre, advantageously polymer bars or the like reinforced with glass fibre, or prefabricated meshes formed thereof. Supporting bars comprising glass fibre, such as polymer bars reinforced with glass fibre, enable a solution which has a lighter weight and is more ecological than ribbed reinforcement bars but which still secures a firm and strong floor structure.
  • the thermal insulation material used in the floor structure according to the invention may be any thermal insulation material that is suitable for the purpose and has a sufficient compression strength.
  • the compression strength of the thermal insulation material to be used should be at least 50 kPa (according to the standard EN 826); typically, the compression strength is between 50 and 200 kPa and most typically between 100 and 700 kPa.
  • the thermal insulation material is extruded polystyrene (XPS), expanded polystyrene (EPS), polyurethane (PIR/PUR), phenolic foam, or PVC foam.

  • the casting compound layer is surrounded by a planar brim formed by the insulation material layer under the casting compound layer at all edges of the structural element; in other words, the brim encircles the structural element. In this way, the casting compound layer does not cover the whole insulation material layer but part of the insulation material layer remains exposed in the edges of the structural element.
  • the width of the planar brim formed by the insulation material layer around the casting compound layer is substantially equal to the length of the ends of the supporting bars extending beyond the side surface of the structural element formed by the insulation material layer.

  • the concrete mixture may be any concrete that is suitable for the purpose and comprises a binding agent.
  • the concrete may be fibre-reinforced concrete, porous concrete, or the like.
  • the casting compound layer formed on the insulation material layer may be formed of a ceramic based casting mixture or compound suitable for the purpose.

  • the fibre matting can be made of glass fibres, carbon fibres or other material having a good tensile strength.

Typically, the thickness of the insulation material layer of the structural element is between 50 and 500 mm or 80 and 300 mm, measured between the planar surfaces of the layer. In an embodiment of the invention, the thickness of the first casting compound layer of the structural element is from 10 to 250 mm or from 10 to 200 mm, measured between the planar surface of the insulation material layer and the planar surface of the casting compound layer. If the insulation material layer comprises grooves, the casting compound layer also fills in the grooves in the insulation material layer, typically having a depth of from 40 to 60 mm. In this way, the adhesive strength of the casting compound layer to the insulation material layer can be considerably increased, and furthermore, the supporting bars required for reinforcing the structure can be arranged in the grooves.
  • the insulation material layer, the supporting bars for reinforcing the structure, and the first casting compound layer are provided in the structure by using prefabricated structural elements which are placed tightly against each other so that the insulation material layers of the prefabricated structural elements are placed against each other.

  • the insulation material layers of the prefabricated structural elements comprise tongues and grooves or other corresponding shapes on the side surfaces, allowing the placement of the insulation material layers of the structural elements tightly against each other.
  • the side surface of the insulation material layer is provided with a locking tongue and groove or a corresponding structure to keep the structural elements tightly engaged so that no gap can be formed between the insulation material layers of the adjacent structural elements when the second casting compound layer is formed for the floor structure, and/or the joint between the structural elements is filled in with the second casting compound.
  • the locking tongue and groove prevent the structural elements from being separated from each other, possibly by pressure of the second casting compound, and the thermal insulation material layer of the floor structure thus remains continuous throughout the area of the floor structure.
  • the casting compound layer of the prefabricated structural element may be covered by a thin layer of the second casting compound, consisting of a casting compound having a higher compression strength and/or hardness than the prefabricated first casting compound layer.
  • the second casting compound is a casting compound having a drying shrinkage ⁇ 0.1 mm/m and a compression strength > 30 MPa.
  • the drying shrinkage of the second casting compound is zero or almost zero.
  • the compression strength of the second casting compound may vary, depending on the material used.
  • the second casting compound comprises magnesium phosphate cement based casting compound.

  • casting compound of the second casting compound layer is arranged in the joints between the structural elements and used for forming a thin uniform surface layer for the floor structure. Further, the surface formed by the second casting compound layer can be coated with a coating suitable for the purpose.
  • the function of the first casting compound layer is to provide the structure with the required strength.
  • the function of the second casting compound is primarily to act as a joint sealing compound between the structural elements and as a coating for the floor structure.
  • the brim formed by the insulation material layer at the edge of the structural elements is larger at the supporting bars than in other parts of the structural element. In this way, a wider joint can be formed of the second casting compound at the supporting bars.
