Definitions

  • the invention relates to a prefabricated component for the construction technique in the form of a plate in which two slices of reinforced concrete are held by a plurality of lattice girders at a distance from each other.
  • the respective lattice girder is embedded in the upper and lower disc.
  • the space between the panes is filled with insulating material.
  • the invention relates to a method for producing such a prefabricated component.
  • a prefabricated component according to the preamble of claim 1. Between the two reinforced concrete slices, the room is filled with foamed polyurethane.
  • Such prefabricated component can be used as a ceiling element in prefabricated houses. These ceiling elements can be manufactured as prefabricated large-sized and can be relatively easily and quickly mounted on a construction site. Elaborate concreting work is thus avoided.
  • screed On the construction site screed in the form of a layer of mortar or mastic asphalt of a few centimeters thick is applied to the upper concrete slab. This screed serves as a floor construction and can be provided with a floor publishing. The screed is laid by hand.
  • a floor heating is included as an integral unit in the plate, which can be used as a ceiling element, floor plate or basement ceiling, immediately.
  • a still required by hand in a conventional plate application of screed and any necessary embedding of the heating cables can be omitted in this screed.
  • the plate produced as prefabricated part has a high economy. The overall required work steps are reduced because the installation of screed is eliminated when mounting on site. In addition, such a plate for the user of a prefabricated house has a high level of comfort.
  • the integration of the heating in the upper concrete slab achieves a double technical effect. On the one hand, it serves the comfort of humans by warming the floor. On the other hand, the existing through the heating of the upper concrete disc heat to the fact that insulating material remains dry in the space and penetrated moisture is not critical.
  • a method for producing a prefabricated component for the construction technique in the form of a plate is specified.
  • an edge formwork is erected on the smooth surface of a steel plate.
  • a lattice girder layer as well as the necessary longitudinal and transverse reinforcement is arranged.
  • a lower pane made of reinforced concrete is produced.
  • heating cables for underfloor heating are fastened to the pre-consolidated longitudinal and transverse reinforcement above the lattice girders.
  • an edge formwork for the upper concrete slab is placed on the smooth surface of the same steel plate or another steel plate.
  • an edge formwork for the upper concrete slab is placed on the smooth surface of the same steel plate or another steel plate.
  • the previously manufactured lower concrete disc is rotated by 180 ° immersed in the liquid concrete and this hardened.
  • the two concrete slabs are at a distance from each other with space exclusively through the lattice girders held. Other spacers that absorb static forces to maintain the distance between the two concrete slabs are not required.
  • Fig. 1 shows a schematic, perspective view of a cross section through a prefabricated component, which can be used as a floor slab, floor slab or basement ceiling.
  • the prefabricated component 10 has a lower concrete disc 12, as well as an upper concrete disc 14, which is generally thicker than the lower concrete disc 12.
  • the end portions of lattice girders 16 are concreted together with a direction indicated by a transverse bar 18 reinforcement. Other reinforcing bars are not shown for reasons of clarity.
  • end sections of the same lattice girders 16 are also embedded in the upper concrete disc 14 together with a reinforcement, indicated by a transverse bar 20.
  • a reinforcement indicated by a transverse bar 20.
  • Above the lattice girders 16 are on the reinforcement 20 heating cables 22 a floor heating. They are also embedded in the upper concrete slab 14.
  • the lattice girders 16 hold the two concrete slabs 12, 14 at a distance from each other. Additional spacers are not required.
  • insulating material 24 is filled.
  • an insulating material for example, in the production polyurethane foam filled and cured.
  • the cured PU foam can support the stability of the entire prefabricated part 10 to some extent.
  • polystyrene beads may also be used as the insulating material.
  • Cellulose flakes and / or mineral wool flakes are used.
  • the loose insulating material can be poured, blown in or sucked in.
  • the outwardly facing surface 26 is smooth, so that on this surface 26 directly a floor covering can be applied.
  • a floor covering z As tiles, parquet or plastic floor can be used.
  • Typical dimensions for the finished part are z. B. for the length I about 5 m to 13 m and for the width b 2.5 m to 3.5 m.
  • the lower concrete disc 12 may have a typical thickness d3 of 40 mm to 60 mm, preferably about 50 mm; the distance d2 between the two concrete slabs 12, 14 and thus the thickness of the space for the insulating material is in the range of 130 mm to 170 mm, preferably at about 150 mm; the thickness d1 of the upper concrete disk 14 is in the range of 80 mm to 100 mm, preferably about 90 mm.
  • FIG. 2 shows the method sequence during the production of a prefabricated component according to FIG. 1 in the form of a flowchart.
  • step S1 a steel pallet of a pallet circulation system is provided.
  • step S2 an edge formwork is erected on the smooth surface of the steel pallet.
  • step S3 lattice girders and optionally the lower reinforcement are arranged and connected to one another within the edge formwork.
  • step S4 concrete is poured into the edge formwork, so that the lower end portions of the lattice girders and the lower reinforcement are embedded in concrete.
  • the pallet is conveyed to a drying oven and the concrete is cured.
  • the lower disc made of reinforced concrete is completed.
  • the upper reinforcement and the heating pipes for underfloor heating are fastened to the lattice girders.
  • This reinforcement layer serves as a support plane for fixing the heating cables.
  • an edge formwork for the upper concrete pane is arranged on the smooth surface of the steel plate of another pallet.
  • the prefabricated concrete disc is rotated by 180 °, so that the cast-in lattice girders can be immersed with their outboard end portions in the liquid concrete (step S9).
  • step S10 the pallet is conveyed into the drying oven and the concrete is cured. It thus creates a plate in which the two concrete slabs are held at a distance from each other with space through the lattice girders.
  • step S6 In the space can now be filled by filling, blowing or sucking loose insulating material, such as polystyrene beads, cellulose flakes or mineral wool flakes.
  • insulating material such as polystyrene beads, cellulose flakes or mineral wool flakes.
  • PU foam can be filled in and cured. It is also possible that after making the lower concrete slab filled with PU foam and this is cured. Only then do the work steps mentioned above in step S6 take place.
