Definitions
- the invention relates to a prefabricated component for building technology in the form of a plate, at the two discs made of reinforced concrete through several lattice girders at a distance are kept apart.
- the respective lattice girder is in the upper and lower Concreted disc.
- the space between the panes is made of insulating material filled.
- the invention further relates to a method for producing a such prefabricated component.
- the plate that as a ceiling element, floor plate or as Basement ceiling can be used, immediately underfloor heating as an integral Unit included.
- a conventional plate still required by hand to apply screed and if necessary the necessary embedding of the heating cables in this screed is not necessary.
- the finished panel as a prefabricated component is extremely economical. The total Required work steps are reduced, because the on-site assembly There is no need to apply screed. It also has such a plate for the user a prefabricated house a high level of comfort.
- the heater By integrating the heater into the upper concrete slab, there is a double technical effect achieved. On the one hand, it serves to comfort people by warming the floor. On the other hand, it serves to heat the The existing concrete on the upper concrete disc means that insulation material in the Interspace remains dry and moisture penetration is not critical.
- a method for producing a Prefabricated component for construction technology specified in the form of a plate is based on the smooth surface of a steel plate Edge formwork erected. A lattice girder layer is created within this edge formwork as well as the necessary longitudinal and transverse reinforcement. By filling in Concrete in the edge formwork and hardening of the concrete becomes a lower pane made of reinforced concrete. Then above the lattice girders Heating cables for underfloor heating on the prefabricated longitudinal and Cross reinforcement attached. On the smooth surface of the same steel plate or Another steel plate is then a formwork for the upper Concrete disc arranged. Concrete is piled up inside the edge formwork.
- the previously made lower concrete disc is turned through 180 ° in the liquid Immersed concrete and this hardened.
- the two concrete disks are in one Distance from each other with space only through the lattice girders held. More spacers that maintain static forces Take up the distance between the two concrete slabs are not necessary.
- the prefabricated component 10 has a lower concrete disc 12, and an upper concrete disc 14, which is generally thicker than the lower one Concrete slab 12.
- the lower concrete disc 12 are the end portions of Lattice girders 16 together with one indicated with a cross bar 18 Reinforced concrete. Additional reinforcement bars are for reasons of clarity not shown.
- end portions of the same lattice girder 16 are also in the upper concrete disc 14 concreted together with a reinforcement, indicated by a cross bar 20. Above the lattice girder 16 there are 20 heating lines 22 on the reinforcement Underfloor heating on. They are also in the upper concrete disc 14 concreted.
- the lattice girders 16 hold the two concrete disks 12, 14 in one Distance from each other. Additional spacers are not required.
- insulating material 24 In the space between the concrete slabs 12, 14 is insulating material 24 filled.
- Polyurethane foam is used as the insulating material, for example, in the manufacture filled and cured.
- the cured PU foam can be in to a certain extent the stability of the entire prefabricated component 10 support.
- polystyrene beads, Cellulose flakes and / or mineral wool flakes can be used. That loose Insulation material can be poured, blown in or sucked in.
- the outwardly facing surface 26 is smooth, so that on it Surface 26 a floor covering can be applied directly.
- a flooring can e.g. B. tiles, parquet or plastic floor can be used.
- Typical dimensions for the prefabricated component are e.g. B. for the length I to about 5 m 13 m and for the width b 2.5 m to 3.5 m.
- the lower concrete disc 12 can typical thickness d3 from 40 mm to 60 mm, preferably from about 50 mm; the distance d2 between the two concrete disks 12, 14 and thus the thickness the space for the insulating material is in the range from 130 mm to 170 mm, preferably around 150 mm; the thickness d1 of the upper concrete disc 14 is in Range from 80 mm to 100 mm, preferably around 90 mm.
- EP-A-1 106 745 Further details on the construction of plate 10 are given in EP-A-1 106 745 thereof Applicant can see, for example, information about the reinforcement as well other fasteners.
- the content of this patent application is hereby incorporated by reference to the disclosure content of the present application included.
- FIG. 2 shows the process sequence when producing a prefabricated component according to FIG. 1 in the form of a flow chart.
- a steel pallet becomes one Pallet circulation system provided.
- the smooth surface of the steel pallet erected an edge formwork.
- step S3 lattice girders and, if necessary, become inside the edge formwork the lower reinforcement arranged and connected to each other.
- step S4 concrete is poured into the edge formwork, so that the lower ones End sections of the lattice girder and the lower reinforcement are embedded in concrete.
- step S5 the pallet is conveyed into a drying oven and the Cured concrete.
- the lower pane made of reinforced concrete is now complete.
- step S6 the upper reinforcement and the Heating cables attached to underfloor heating.
- This reinforcement layer serves as Carrier level for fixing the heating cables.
- one is on the smooth surface of the steel plate another pallet arranged a formwork for the upper concrete slab.
- the previously made concrete disc is rotated by 180 ° so that the concreted in Lattice girders with their outward-facing end sections in the liquid concrete can be immersed (step S9).
- the pallet is then conveyed into the drying oven in step S10 and the Cured concrete. This creates a slab with the two concrete slices held at a distance from each other with space by the lattice girders are.
- Loose space can now be added by filling, blowing or sucking in Insulation material such as polystyrene beads, cellulose flakes or Mineral wool flakes can be filled in.
- Insulation material such as polystyrene beads, cellulose flakes or Mineral wool flakes can be filled in.
- PU foam can be filled in and be cured. It is also possible that after finishing the bottom concrete disc filled with PU foam and this is cured. First The work steps mentioned above in step S6 then take place.
