~he invention relates to a flow distribu~ing conduit means, comprising a first and a second sheet being S substantially impervious to a flow medium and being arranged in parallel.
Presently a plurality of constructions are used as intermediate floor structures. In smaller houses the most common intermediate floor structure comprises joist frames provided with building sheets preferably on the underside of the ~oists as well as on the upper side thereof.
In connection with smaller house also a plurality of other constructional methods exists, for instance cast intermediate floors and different types of pre-fabricated intermediate floors provided with constructional elements made of light concrete or ordinary concrete.
In larger buildings normally intermediate floors made of concrete cast in situ or pre-fabricated concrete elements, for instance elements made of light concrete are utilized. ~ight wooden constructions are used only in exeptional ca~es in larger buildings.
Lately a comparatively new type of pre-fabricated die elements have been introduced on the market. This is a type of large elements having a die ready for casting and having al80 an integrated framework made of reinforcement bars.
After mounting said elements and after all installations made on the upperside of said elements the casting of concrete prepared. Such a system has several advantages, for instance a fast mounting, a low constructional height, ~

As a consequence the building time is substantially extended which increases the building interest cos~s. In the types of constructions mentioned above for intermediate floor structures said floor structure has no other function than dividing the building into floor plans.
Howeever, construc~ions of intermediate floors exist which comprise some kind of heating device. Said heating device normally comprises electric heating coils, but also coils of piping for hot water, which are arranged in other parts of said intermediate floor, exist. There are also heating devices for intermediate floors in which water is circulated and which are arranged on top of the intermediate floor.
Common to all the heating devices mentioned above is that they provide local heating and thereby any desired comfort in certain areas, such as bathrooms and toilets. To achieve an efficient heating high temperatures are required in the heating device. Normal temperatures are from 30 -40. However, common to them are also drawbacks, such as being expensive and requiring large demands for labour during installation, but most importan~, they are not reliable during longer time intervals. For instance may electrically heating coils be short circuited when driving a nail into the floor. Similar problems are present also in water carried heating devices in which water tubes can be punctured by a nail. Additionally there is a risk which is not negligable for water leakage as a result of settings in the house and as a result of fatigue by aging.
In larger building, mainly in multiple-unit dwelling houses, problems with a very poor sound reduction between floor plans are noticed, especially if l~sLmple" cons~ruc-tions are used.

num. The profile is dLmensioned for each building. On top o~ said first profile 10 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. In a groove ofsaid profile 10 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 trans~erse 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 shee$ 10, ' for instance by a screw joint. On top of said sheet 13'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.

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. In said restriction sheet 12 apertures 25 and 26 are formed, said apertures having an increasing diameter from a connection piece 27 through which heated air is supplied from a conduit 17a.
The intermediate floor structure comprises also a number of joist frames 18, on which said sound reducing sheet 23 are attached by gluing or in another suitable way.
With reference to PIG. 3 it is clear that the intermediate floor structure according to the invention comprises three ducts 17a, 17b, 17c, through which heated air is supplied to the intermediate floor structure in a method further disclosed below with reference to FIG. 6.
For the heating o air to be fed into the inter-mediate ~loor structure a heating means 19 is arranged on the other side of said intermediate floor struc~ure.
Preferably said heating means 19 is arranged centrally in the house, so as to minimize heat and flow losses in said ducts 17a-c. In other not shown embodiments said heating means is replaced by several smaller units disposed so as to facilitate an individual control of parts of the floor structure. Said heating means 19 comprises in the shown embodiment an electric battery l9a, but it is possible to provide in said heating means a water heater having the desired power and also to provide said heating means with a heat exchanger which is connected to a heat pump, so as to achieve a further decrease in heat losses in the building.
Said heating means comprises-also a fan l9b and is provided with a plurality of outputs l9c for blowing out heated air, and a number of inlets l9d through which air is-drawn. Said outputs l9c of said heating means are connected to said ducts 17a-17c, from which heated air is fed into the , -.

The inputs l9d of said heating means is in the shown embodiment connected to the space within the grooves below said sheet 13 for return suction of air which has emitted heat to said heat accumulating l,ayer 14.
FIG. 5 shows a part of a intermediate floor structure in a cross-sectional view similar to FIG. 2 and from said figuxe it is clear how the intermediate floor structure is connected to an outer wall. On top of a lower wall 28/
shown as a basement outer wall in the embodiment, is arranged a horizontal edge beam 22 made of plywood.
Vertically on said edge beam 22 is arranged a similar edge beam 21, in which said profile 10 is attached. On top of the intermediate floor structure i8 arranged an upper outer wall 29 covered by a facade layer 30. Such a construction is very well ~uited when assembling said intermediate floor structure on site. When assembling, 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. Several sections of said sheets 10 are arranged side by side with some conventional over-lapping. Outside of said shee~s 10 are provided vertical edge beams 21 to which said shets 10 are attached. The building has now very rapidly been provided with a floor structure withstanding walking on and lowering to a high extent the risks for the installer of said intermediate floor structure when continuing the installation efforts.
Sheets 13 are arranged on top of said sheets 10, the grooves of said sheets 10 crossing--grooves of said sheets 13. Said-sheets-13 constitute together:with-said ver~ical edge beams 21 a casting mould when casting said heat -accumulating concrete layer 14. Said sheets 13 also form;a bsttom reinforcement for said concre~e layer decreasing , . : , , WO91/07~57 , PCT/SE90/00726 ~. :
substantially the reinforcement of said layer as compared to conventional concrete floor structures. In some loading circumstances it is even possible to exclude reinforcement of said concrete layer 14.
With reference to FIG. 6 the heating up and control-ling of conditions in dwelling spaces above said inter-mediate floor structure will be described in more detail.
Air is heated in said heating device 19 and is fed through not shown pipings to said ducts 17a, 17b, 17c, through which air is fed into said intermedia~e floor structure. In appropriate positions along the length of said ducts 17a-17c said connection pieces 27 are arranged for discharging air into said conduits 11, which are covered by said restriction sheets 12. Air fed through said duct 17c is discharged in a first connection piece 27c from which it is fed through conduits 11 and through said restrict.ion sheet further to spaces below said sheet 13. Some of the heat of the air is transferred to said heat accumulating layer 14 during the flow of air through grooves of said sheet 13.
The air flow is then collected in conduits 11 through a restriction sheet 12d. The area below which said air has flown belongs to a first zone C, D, the heatsupply thereto thus being determed by the air supplied through said conduit 27c.and said restriction sheet 12c. In the same way air is supplied a.connection piece 27a through said duct 17a from which air is supplied to a second zone A of said intermediate floor structure through a conduit 11 and a restriction sheet 12a. By such a zone distribution of the heated are there is accomplished an individual control of temperature in separate parts of dwelling areas. For instance a-restriction of flow of heated air to~a zone below.a bedroom can be accomplished by control means ~
arranged in a connection piece 27 or in said restriction-sheet 12.

~ WO91/07557 2 ~ 7 3 0 3 9 PCT/SE90/00726 Said restriction sheet 12 f~nctions 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. In an alternative embodiment 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.
In the embodiment shown in the figures air is cirku-lated in a closed system. However, according to the inven-tion it is possible also to arrange an inlet of pre-heated fresh air which is supplied to dwelling spaces as ventila-tion air after being fed through said intermediate floor structure.
In an alternative embodLment according to the inven-tion no connection pieces 27 are arranged but instead apertures are made in the bottommost section of said profile 10 just in front of said dict 17. By supplying a covering layer below said profile 10 i-t is also possible to u~e the groove of said profile 10, which is open at the bottom, as a conduit 11, apertures corresponding to-apertures in said restriction sheet 12 being made in the upper closed section of the profile 10, and apertures also being made in $he underlaying layer in front of said duct 17 for the supply of heated air. - ; -- The invention is applicable also during such-s temperature co~ditions when-cooling is desired.~In~such~-~
applications said heating device is replaced by or combined with a cooling device.

WO91/075~7 2 ~ 7 3 ~ ~ 9 PCT/SE90/00726 !:, In the embodLment shown in FIG. 7 the flow distributing conduit means according to the present invention comprises two sheets 113 and 110 arranged in `
parallel. Each of said sheets are made of a material substantially impervious to a flow medium. In the shown embodiment the sheets are made of corrugated sheet metal which is a very suitable material. The sheets have grooves extending in the longitudinal direction and the sheets are arranged on top of each other in such a way that said grooves form a right angle. Each groove of one of the sheets thereby provides a connection between the grooves of the second sheet, and a flow medium fed through said conduit means can moove freely and be distributed in said conduit means. Two sheets are put to overlap each other so as to achieve the required continuity when mounting the elements. By fixedly connecting said sheets a rigid unit is provided which is self-supporting and which can be used in different applications. The sheets 113 and 110 can be connected by using for instance self-driving screws, rivets, spot welding, gluing etc.
In the ambodiment described above the conduit means is applicable in a variaty of application areas, such as heat exchangers, heating elements and the like. Common to different applications is that high distributing ability and large area towards the environment of the conduit means is used. If the conduit means is intended for use in an intermediate floor structure it is suitably provided with insulating and/or a complete false ceiling.
From FIG. 8 it is clear how a flow medium, for instance air, is supplied to and circulates in a rectangu- -lar conduit means according to the invention. Along side edges-of said condllit means walls connecting said sheets have been arranged to prevent-the medium-from leeving the conduit means. Two inlet ducts 117a and 117b convey said . .

W O 91/07557 PC~r/SE90/00726 medium from a pump and heating means 119 to conduits llla and lllb which are provided along to adjacen1 side edges o~
the conduit means. Said conduits llla and ll:Lb 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 flow medium is introduced in said conduit llla and lllb through inlet ducts 117a and 117b under pressure. From said ducts said medium enters a first groove of said first sheet and therefrom it is distributed through the conduit means emitting heat to or receiving heat from said conduit means. Through outle~ openings of the lower pressure side of said pump means said medium leaves the conduit means and is drawn into said pump means, thereby closing a circulating process.
In the application according ~o the invention shown in FIG. 9 a conduit means according to the invention is used in an intermediate ~loor structure. From a centrally disposed pump means 119 air is driven into conduits llla and lllb through inlet ducts 117a and 117b and further into said conduit means. The air then returns to the low pressure side of said pump means through the conduit means during heat emission to other parts of the intermediate floor structure.
FIG. 10 and 11 show in more detail the construction of an intermediate floor structure in a building when utilizing the conduit means according to the invention. Two pre-assembled sheets 113 and 110 are put on walls thereby forming a floor layer which can be stepped upon during the building process. On top of the upper sheet 113 inlet ductsll7a and--117b are arranged, said ducts being connected -to conduits llla and-lllb arranged along the outer wallsiof said building. Set inlet ducts 117a andi117b are insulated so-as to decreas heat losses during the conveyance towar~s said conduits llla and lllb. The upper corrugation, i.e.

2~73039 ~ 12 the sheet 113, is designed to constitute a bottom rein-forcement for a concrete layer 114 which is cast on top of said sheet 113 when an edge element 121 is disposed outside said conduit means along the outer walls of said building.
Said edge elements 121 and said conduit means thereby con-stitute the mould when casting. Thus, in this embodLment the inlet ducts 117a, 117b are arranged in the concrete layer 114. Said conduits llla and lllb are connected directly to the grooves of said upper sheet 113 to which the air is transferred and thsn distributed in the entire conduit means. To prevent leakage of ~he flow medium from the conduit means walls shaped as beams 135 and 136 are arranged in the end parts of said grooves so as to close said grooves. 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. I~owever, less reinforcement than in a conventional concrete slab is required thanks to the bottom reinforcement.
It is appropriate to use the conduit means according to the invention as a rigid and very compressed element for an intermediate floor structure, the thickness thereof being as low as 75 mm. It is possible to pro~uce large elements, dimensions thereof being at least 2250x12000 mm.
The dead weight is as low as 15 kg per m2. As a result of large elements the mounting of the elements on side is very ~ast. Elements compressed with regard to heights combined with low weight make transporting more effective wi~h regard to volume-as well as to casts. In practice this ~ -means, that up to 1200 m2 of elements can be conveyed on a truck with a trailer. The normal quantity in transport for other types of intermediate floor structure elements is :. ., . ' , :: . ~;. :
~ . , .
; WO91/07557 2`0 7~ o 3 9 PCT/SE90/00726 from 1130 to 150 m2 on a corresponding truck and trailer.
The difference depends both on the weight and the volume.
In a structural sence the construction gives a combined effect in that the upper corrugated ishet function both as a remaining mould and as a bottom reinforcement.
Furthermore, it is possible to make installations of tubes and other types of technical installations in a conven-tional way either on the upper side of the system of -elements before casting or on the underside of the system of elements after casting. Besides the advan~ages with the system of elements described above two unique advantageous characterize the invention.
It is favourable to transport airtgas in all direc-tions in the sheets because the element system comprises corrugated sheets which are layed crosswise. A practical benefit and use of this fact can for instance be to convey heated or cooled air between said sheets and obtain control of conditions in the dwelling space above the intermediate floor structure. Another essential advantage is that it is very easy to ins~all electrical installation tubes and fresh water pipelines in conduits extending in the longitu-dinal direction and the transverse direction, respectively, which are formed between the two corrugated sheets. In practice this means that technical installations can be made above, under and within the intermediate floor structure element.
If the choice is not to use any kind of insulation or other type of false ceiling the conduit means by itself can function as a complete false ceiling by being painted/sur-face conditioned at delivery.
The invention is not lLmited in utilizing a certaintype of corrugated sheets 113 and 110. The reason for ~his is that a plurality of corrugated sheets 113 are available at the market and have a combined ef~ect in accordance with " ' '.', , ' " ' ' ' . ' ' ' ' " ';, ~'" ''' ' ` ' , ,' .

num. The profile is dLmensioned for each building. On top o~ said first profile 10 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. In a groove ofsaid profile 10 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 trans~erse 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 shee$ 10, ' for instance by a screw joint. On top of said sheet 13'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. On top of said heat accumulating layer 14 is provided a coating 16 made of some kind of conventional floor ~aterial having a suitable specific heat transfer. A
sheet 23 ~ade of sound reducing material, such as rubber, is arranged in contact with the underside of 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. In said restriction sheet 12 apertures 25 and 26 are formed, said apertures having an increasing diameter from a connection piece 27 through which heated air is supplied from a conduit 17a.
The intermediate floor structure comprises also a number of joist frames 18, on which said sound reducing sheet 23 are attached by gluing or in another suitable way.
With reference to PIG. 3 it is clear that the intermediate floor structure according to the invention comprises three ducts 17a, 17b, 17c, through which heated air is supplied to the intermediate floor structure in a method further disclosed below with reference to FIG. 6.
For the heating o air to be fed into the inter-mediate ~loor structure a heating means 19 is arranged on the other side of said intermediate floor struc~ure.
Preferably said heating means 19 is arranged centrally in the house, so as to minimize heat and flow losses in said ducts 17a-c. In other not shown embodiments said heating means is replaced by several smaller units disposed so as to facilitate an individual control of parts of the floor structure. Said heating means 19 comprises in the shown embodiment an electric battery l9a, but it is possible to provide in said heating means a water heater having the desired power and also to provide said heating means with a heat exchanger which is connected to a heat pump, so as to achieve a further decrease in heat losses in the building.
Said heating means comprises-also a fan l9b and is provided with a plurality of outputs l9c for blowing out heated air, and a number of inlets l9d through which air is-drawn. Said outputs l9c of said heating means are connected to said ducts 17a-17c, from which heated air is fed into the , -.

The inputs l9d of said heating means is in the shown embodiment connected to the space within the grooves below said sheet 13 for return suction of air which has emitted heat to said heat accumulating l,ayer 14.
FIG. 5 shows a part of a intermediate floor structure in a cross-sectional view similar to FIG. 2 and from said figuxe it is clear how the intermediate floor structure is connected to an outer wall. On top of a lower wall 28/
shown as a basement outer wall in the embodiment, is arranged a horizontal edge beam 22 made of plywood.
Vertically on said edge beam 22 is arranged a similar edge beam 21, in which said profile 10 is attached. On top of the intermediate floor structure i8 arranged an upper outer wall 29 covered by a facade layer 30. Such a construction is very well ~uited when assembling said intermediate floor structure on site. When assembling, 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. Several sections of said sheets 10 are arranged side by side with some conventional over-lapping. Outside of said shee~s 10 are provided vertical edge beams 21 to which said shets 10 are attached. The building has now very rapidly been provided with a floor structure withstanding walking on and lowering to a high extent the risks for the installer of said intermediate floor structure when continuing the installation efforts.
Sheets 13 are arranged on top of said sheets 10, the grooves of said sheets 10 crossing--grooves of said sheets 13. Said-sheets-13 constitute together:with-said ver~ical edge beams 21 a casting mould when casting said heat -accumulating concrete layer 14. Said sheets 13 also form;a bsttom reinforcement for said concre~e layer decreasing , . : , , WO91/07~57 , PCT/SE90/00726 ~. :
substantially the reinforcement of said layer as compared to conventional concrete floor structures. In some loading circumstances it is even possible to exclude reinforcement of said concrete layer 14.
With reference to FIG. 6 the heating up and control-ling of conditions in dwelling spaces above said inter-mediate floor structure will be described in more detail.
Air is heated in said heating device 19 and is fed through not shown pipings to said ducts 17a, 17b, 17c, through which air is fed into said intermedia~e floor structure. In appropriate positions along the length of said ducts 17a-17c said connection pieces 27 are arranged for discharging air into said conduits 11, which are covered by said restriction sheets 12. Air fed through said duct 17c is discharged in a first connection piece 27c from which it is fed through conduits 11 and through said restrict.ion sheet further to spaces below said sheet 13. Some of the heat of the air is transferred to said heat accumulating layer 14 during the flow of air through grooves of said sheet 13.
The air flow is then collected in conduits 11 through a restriction sheet 12d. The area below which said air has flown belongs to a first zone C, D, the heatsupply thereto thus being determed by the air supplied through said conduit 27c.and said restriction sheet 12c. In the same way air is supplied a.connection piece 27a through said duct 17a from which air is supplied to a second zone A of said intermediate floor structure through a conduit 11 and a restriction sheet 12a. By such a zone distribution of the heated are there is accomplished an individual control of temperature in separate parts of dwelling areas. For instance a-restriction of flow of heated air to~a zone below.a bedroom can be accomplished by control means ~
arranged in a connection piece 27 or in said restriction-sheet 12.

In an alternative embodiment 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.
In the embodiment shown in the figures air is cirku-lated in a closed system. However, according to the inven-tion it is possible also to arrange an inlet of pre-heated fresh air which is supplied to dwelling spaces as ventila-tion air after being fed through said intermediate floor structure.
In an alternative embodLment according to the inven-tion no connection pieces 27 are arranged but instead apertures are made in the bottommost section of said profile 10 just in front of said dict 17. By supplying a covering layer below said profile 10 i-t is also possible to u~e the groove of said profile 10, which is open at the bottom, as a conduit 11, apertures corresponding to-apertures in said restriction sheet 12 being made in the upper closed section of the profile 10, and apertures also being made in $he underlaying layer in front of said duct 17 for the supply of heated air. - ; -- The invention is applicable also during such-s temperature co~ditions when-cooling is desired.~In~such~-~
applications said heating device is replaced by or combined with a cooling device.

WO91/075~7 2 ~ 7 3 ~ ~ 9 PCT/SE90/00726 !:, In the embodLment shown in FIG. 7 the flow distributing conduit means according to the present invention comprises two sheets 113 and 110 arranged in `
parallel. Each of said sheets are made of a material substantially impervious to a flow medium. In the shown embodiment the sheets are made of corrugated sheet metal which is a very suitable material. The sheets have grooves extending in the longitudinal direction and the sheets are arranged on top of each other in such a way that said grooves form a right angle. Each groove of one of the sheets thereby provides a connection between the grooves of the second sheet, and a flow medium fed through said conduit means can moove freely and be distributed in said conduit means. Two sheets are put to overlap each other so as to achieve the required continuity when mounting the elements. By fixedly connecting said sheets a rigid unit is provided which is self-supporting and which can be used in different applications. The sheets 113 and 110 can be connected by using for instance self-driving screws, rivets, spot welding, gluing etc.
In the ambodiment described above the conduit means is applicable in a variaty of application areas, such as heat exchangers, heating elements and the like. Common to different applications is that high distributing ability and large area towards the environment of the conduit means is used. If the conduit means is intended for use in an intermediate floor structure it is suitably provided with insulating and/or a complete false ceiling.
From FIG. 8 it is clear how a flow medium, for instance air, is supplied to and circulates in a rectangu- -lar conduit means according to the invention. Along side edges-of said condllit means walls connecting said sheets have been arranged to prevent-the medium-from leeving the conduit means. Two inlet ducts 117a and 117b convey said . .

W O 91/07557 PC~r/SE90/00726 medium from a pump and heating means 119 to conduits llla and lllb which are provided along to adjacen1 side edges o~
the conduit means. Said conduits llla and ll:Lb 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 flow medium is introduced in said conduit llla and lllb through inlet ducts 117a and 117b under pressure. From said ducts said medium enters a first groove of said first sheet and therefrom it is distributed through the conduit means emitting heat to or receiving heat from said conduit means. Through outle~ openings of the lower pressure side of said pump means said medium leaves the conduit means and is drawn into said pump means, thereby closing a circulating process.
In the application according ~o the invention shown in FIG. 9 a conduit means according to the invention is used in an intermediate ~loor structure. From a centrally disposed pump means 119 air is driven into conduits llla and lllb through inlet ducts 117a and 117b and further into said conduit means. The air then returns to the low pressure side of said pump means through the conduit means during heat emission to other parts of the intermediate floor structure.
FIG. 10 and 11 show in more detail the construction of an intermediate floor structure in a building when utilizing the conduit means according to the invention. Two pre-assembled sheets 113 and 110 are put on walls thereby forming a floor layer which can be stepped upon during the building process. On top of the upper sheet 113 inlet ductsll7a and--117b are arranged, said ducts being connected -to conduits llla and-lllb arranged along the outer wallsiof said building. Set inlet ducts 117a andi117b are insulated so-as to decreas heat losses during the conveyance towar~s said conduits llla and lllb. The upper corrugation, i.e.

2~73039 ~ 12 the sheet 113, is designed to constitute a bottom rein-forcement for a concrete layer 114 which is cast on top of said sheet 113 when an edge element 121 is disposed outside said conduit means along the outer walls of said building.
Said edge elements 121 and said conduit means thereby con-stitute the mould when casting. Thus, in this embodLment the inlet ducts 117a, 117b are arranged in the concrete layer 114. Said conduits llla and lllb are connected directly to the grooves of said upper sheet 113 to which the air is transferred and thsn distributed in the entire conduit means. To prevent leakage of ~he flow medium from the conduit means walls shaped as beams 135 and 136 are arranged in the end parts of said grooves so as to close said grooves. 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. I~owever, less reinforcement than in a conventional concrete slab is required thanks to the bottom reinforcement.
It is appropriate to use the conduit means according to the invention as a rigid and very compressed element for an intermediate floor structure, the thickness thereof being as low as 75 mm. It is possible to pro~uce large elements, dimensions thereof being at least 2250x12000 mm.
The dead weight is as low as 15 kg per m2. As a result of large elements the mounting of the elements on side is very ~ast. Elements compressed with regard to heights combined with low weight make transporting more effective wi~h regard to volume-as well as to casts. In practice this ~ -means, that up to 1200 m2 of elements can be conveyed on a truck with a trailer. The normal quantity in transport for other types of intermediate floor structure elements is :. ., . ' , :: . ~;. :
~ . , .
; WO91/07557 2`0 7~ o 3 9 PCT/SE90/00726 from 1130 to 150 m2 on a corresponding truck and trailer.
The difference depends both on the weight and the volume.
In a structural sence the construction gives a combined effect in that the upper corrugated ishet function both as a remaining mould and as a bottom reinforcement.
Furthermore, it is possible to make installations of tubes and other types of technical installations in a conven-tional way either on the upper side of the system of -elements before casting or on the underside of the system of elements after casting. Besides the advan~ages with the system of elements described above two unique advantageous characterize the invention.
It is favourable to transport airtgas in all direc-tions in the sheets because the element system comprises corrugated sheets which are layed crosswise. A practical benefit and use of this fact can for instance be to convey heated or cooled air between said sheets and obtain control of conditions in the dwelling space above the intermediate floor structure. Another essential advantage is that it is very easy to ins~all electrical installation tubes and fresh water pipelines in conduits extending in the longitu-dinal direction and the transverse direction, respectively, which are formed between the two corrugated sheets. In practice this means that technical installations can be made above, under and within the intermediate floor structure element.
If the choice is not to use any kind of insulation or other type of false ceiling the conduit means by itself can function as a complete false ceiling by being painted/sur-face conditioned at delivery.
The invention is not lLmited in utilizing a certaintype of corrugated sheets 113 and 110. The reason for ~his is that a plurality of corrugated sheets 113 are available at the market and have a combined ef~ect in accordance with " ' '.', , ' " ' ' ' . ' ' ' ' " ';, ~'" ''' ' ` ' , ,' .
