Definitions

• An object of the present invention is to substan- tially overcome the problems mentioned above and also to make possible a fast and comparatively simple assembly of a very rigid and sound-reducing intermediate floor structure.
• the intermediate floor structure according to the invention is also cheap and has outer dimensions corresponding to intermediate floor structures common at present. According to the invention there is accomplished also a control of the conditions in dwelling areas by a "soft" heat emission to said areas. Furthermore, the time required for the drying-out of concrete in a floor structure is substantial- ly reduced.
• Another object of the present invention is to sub ⁇ stantially eliminate the drawbacks of heavy element systems which are also difficult to mount. At the same time all positive properties of pre-fabricated die elements described above remain with the invention. Furthermore, there are other completing advantages when using the invention.
• FIG. 1 is a cross-sectional view of an intermediate floor structure according to the invention
• FIG. 2 is a cross-sectional view of an intermediate floor structure according to the invention, said view being in right angle to the section of FIG. 1,
• FIG. 7 is a perspective view of a conduit means according to the invention.
• the intermediate floor structure shown in FIG. 1 comprises as a supporting part a corrugated sheet 10, for instance shaped as a "TRP-profile" made of steel or alumi- num.
• the profile is dimensioned for each building.
• a second corrugated sheet 13 is arranged in right angle to said first profile, said second sheet 13 functioning as a distributing profile for incom- ming heated air and for outgoing cooled air.
• a conduit 11 is arranged for the supply of air.
• the conduit 11 is connected through a restriction sheet 12 to grooves extending in the transverse direction of the conduit 11 and being defined by said sheet 13 in the upper side.
• the function of said restriction sheet 12 is described in more detail with reference to FIG. 6.
• Said sheet 13 is suitably fixedly connected to said sheet 10, for instance by a screw joint.
• a heat accumulating layer 14 is arranged, said layer consisting in the shown embodiment of concrete and conventionally arranged reinforcement bars 20.
• Said layer 14 can also consist of gypsum or other materials having heat accumulating properties, such as different types of building sheets. Said layer 14 has only in exceptional cases a minor supporting function making the choice of material free.
• a coating 16 made of some kind of conventional floor material having a suitable specific heat transfer.
• a sheet 23 made of sound reducing material, such as rubber, is arranged in contact with the underside of said profile
• a conventional insulating layer 15 and below said insula ⁇ ting layer a sheet 24 made of gypsum.
• said insulating layer 15 is excluded and some kind of false ceiling sheet is arranged in contact with said sheet 23 or directly in contact with said sheet 10.
• a tube having apertures in the upper side thereof can be arranged in the groove formed in said profile 10. From FIG. 2 it is more clear how said profile 13 is formed and how said restriction sheet 12 separates the space in the grooves of said profile 10 from the space in the grooves below said profile 13.
• FIG. 5 shows a part of a intermediate floor structure in a cross-sectional view similar to FIG. 2 and from said figure it is clear how the intermediate floor structure is connected to an outer wall.
• a lower wall 28 shown as a basement outer wall in the embodiment, is arranged a horizontal edge beam 22 made of plywood.
• a similar edge beam 21 in which said profile 10 is attached.
• an upper outer wall 29 covered by a facade layer 30.
• Such a construction is very well suited when assembling said intermediate floor structure on site.
• the underlaying outer wall 28 is constructed firstly and said horizontal edge beam 22 is attached thereto. Secondly sections of said sheet 10 available in lengths corresponding to the width of said building, are put out.
• Said restriction sheet 12 functions also as a distri ⁇ butor for the heated air along one side of each zone so as to provide the desired distribution of air below the sheet 13 accomplishing also a control of emission and reception, respectively, of heat.
• said restriction sheet 12 comprises one fixed section, which is provided with apertures for letting out air, and one movable section which is slidable by a control in each end. By means of said movable section supplied air is distributed either linearly along the complete restriction sheet or is the distribution of air made along a distributing conduit. Control of air supply is possible before, during and after the process of building.
• a flow medium for instance air
• a flow medium for instance air
• a flow medium for instance air
• a flow medium for instance air
• walls connecting said sheets have been arranged to prevent the medium from leeving the conduit means.
• Two inlet ducts 117a and 117b convey said medium from a pump and heating means 119 to conduits Ilia and 111b which are provided along to adjacent side edges of the conduit means.
• Said conduits Ilia and 111b are connec ⁇ ted with one of the grooves of said first sheet 113 (see also FIG. 11) by apertures distributed along the longitu ⁇ dinal direction.
• a conventional false ceiling 124 is arranged below said lower sheet 113. Also other structures of false ceilings made especially for the conduit means are used in certain applications. Reinforcement bars 120 are embedded in said concrete layer 114. However, less reinforcement than in a conventional concrete slab is required thanks to the bottom reinforcement.
• conduit means by itself can function as a complete false ceiling by being painted/sur- face conditioned at delivery.
• the invention is not limited in utilizing a certain type of corrugated sheets 113 and 110.
• the reason for this is that a plurality of corrugated sheets 113 are available at the market and have a combined effect in accordance with the description.
