Definitions
- the invention relates to an arrangement according to the preamble of claim 1.
- the arrangement can be made either by mounting prefabricated whole plates of concrete or other suitable material, or by building the floor structure plate at the building site.
- the material on top of the floor structure should have good heat-conducting and heat-distributing characteristics, to obtain a good function and heat distribution.
- floor structures made of concrete are substantially used, which are often provided with some type of sound insulation on the top to achieve an acceptable sound level between the floors.
- floor structures of concrete have relative good air sound insulating characteristics, but relatively unsatisfactory step sound insulating characteristics.
- a mould Before casting, a mould should be mounted at the underside of the future concrete plate at site built floor structures. This mould must be supported underneath with so called braces and ledgers, which is a time consuming and expensive work and hinders passage.
- Tubes for ventilation, drain and water which should be placed horizontally in connection to the floor structure, must often be arranged or built-in under the floor structure in site built as well as in prefabricated floor structures. This is a cost raising action which also results in that the building height between the different floors in a building is negatively affected.
- the object of the invention is to solve the above mentioned problem in an effective way regarding economy and function, by making it possible to, in a site built floor structure, build in a floor heating system with air as heat carrier, where the risk of damages in the heating system through mechanical damage from the top and bottom respectively of the floor structure is eliminated, at the same time as a good heat distribution is achieved through that the top of the floor structure is provided with a concrete layer or other similar heat-conducting and heat-distributing material.
- the object is to make the heated air circulate in a closed cavity inside the floor structure, between a heat-insulating layer at the bottom of the floor structure and the heat-conducting layer at the top of the floor structure and to provide adaption to different sound demands between upper and lower floors will be adjusted by variation of the building height of the floor structure and the comprised material.
- the cavity between the bottom and top layer is divided by heat-insulating vertical insulations, which can correspond to the room partition in the upper floor.
- the air which is blown into the different insulated cavities in the floor structure could if desired, be heated to different temperatures by a simple adjustment via thermostats in the different upper rooms. This enables that desired temperature can be provided in these different rooms.
- the floor structure should be able to be built with a large span, similar to beam systems and prefabricated floor structure plates of concrete or other material that exist today, without using cost raising so called braces and ledgers.
- the object is also to be able to arrange the tubes for ventilation, drain and water inside the floor structure, between the heat-insulating layer at the bottom and the heat-conducting layer on top of the floor structure, with the same possibilities to easy reach for service and reparation as a separate substructure below the floor structure provides. This results in savings in material as well as in work cost.
