Abstract

The present invention encompasses a construction element formed as a wall portion ('B') with one or more ducts integrated in the construction element, where a first such duct (112') can be adaptable for and intended for air exchange, by permitting the passage therethrough of an air current, and/or where a second such duct (122') can be adaptable for and intended for a raceway or cable conduit, by permitting the passage therethrough of one or more optical and/or electrical cables and/or the like. Said construction element ('B') is structured with outer panel-shaped wall portions (3, 4) and with a frame construction oriented between these wall portions and adapted for fixedly supporting the wall portions. The duct (112') is adapted to be able to extend along the construction or wall element ('B') and be oriented close to its one, such as its inner, wall portion (4). Said duct (112') is adapted to terminate at its distal and open end section, either in association with the diverging short ends ('B6A') of the wall portion or in association with a roof portion and/or bottom portion allocated an element, where said termination is adapted to take place either in association with a terminal box (112) coordinable with the open end of the duct or with a coupling box or piece.

Description

TITLE OF THE INVENTION: A wall-related construction element. (Connection devices)

TECHNICAL FIELD

The present invention relates in general to a wall-related construction element, which implies that said construction or wall element is principally to be put to use as a prefabricated inner wall, but as an alternative proposed embodiment may also be put to application at an outer wall.

The present invention specially discloses integrating in one or more of these construction elements different types of ducts and raceways and where these ducts and raceways in a first embodiment will relate to ducts with their associated outer walls, their roof portions and their bottom portions formed from thin sheet and where the different portions can advantageously be formed by bending of a thin selected sheet blank material.

Ducts and raceways can in another embodiment and secondly relate to tubular ducts, ducts with circular cross section and the like.

A first such duct may be adaptable for and intended for air exchange by permitting the passage of an air current therethrough.

A second such raceway or duct can then be adaptable for and intended for an electric cable raceway by permitting the passage therethrough of one or more electrical, optical or corresponding conductors or cables and/or the like.

More specifically the present invention is based on a construction element formed as a wall portion, with one or more ducts or raceways integrated in the construction element, said construction element advantageously being structured with outer panel-shaped wall portions and with one or more frame constructions, oriented between these wall portions and adapted for fixedly supporting the wall portions.

Construction elements of the type contemplated here can thus be applied to outer walls with considerably thicker layers for insulating heat and/or sound, with air gaps and diffusion-impeding layers.

BACKGROUND ART

Methods, arrangements and constructions related to the above-disclosed technical field and with a function and a nature, which satisfy set requirements are previously known in a plurality of different embodiments.

As one example of the state of the art and the technical field to which the present invention relates mention might be made that, in house constructions, there are required installations of a multiplicity of conduits and/or ducts, for different purposes and with different cross sections and dimensions.

Thus it is known in the art to install, for air exchange of formed spaced, thin plate formed ducts and cause these to be drawn invisibly through outer wall portions, and where as a rule difficulties occur in association with angling duct sections from one wall portion to another, where it is necessary to insert specially formed joint pieces.

As regards plumbing for water-borne heat and/or tap water there is also a manifest desire to dispose this piping within walls, forming inner walls and/or outer walls. Also here, a prefabricated forming of ducts has been proposed, within which these pipes can simply be passed in and/or led out.

Finally as regards ducts for optical, electrical and similar cables and conduc- tors for information transfer this or these conduits have been put into effect with the aid of flexible plastic tubes. The present invention is intended to have advantageous application in a wall- related construction element, such as in an inner wall, with one or more ducts or raceways integrated in the construction element.

Said duct or ducts may advantageously further, in production from a thin ben- dable and/or punchable sheet metal material, be formed with in any event two opposing side portions, serving as duct-related and/or duct associated wall or side portions, an upper portion, designated roof portion, and a lower portion, designated bottom portion.

It is previously known, within this technical field and the art, to flex and bend a sheet metal blank material, such as a corrosion resistant sheet metal blank material to a tube or duct form, where advantageously the bending can take place in order to be able to form different right-angled cross sections.

Thus, belonging to the state of the art is a large number of selected configurations for conduit or duct cross sections, with associated connection parts, connection boxes and/or cable passage boxes.

Various prefabricated construction elements have been produced with the intention of driving fabrication rate as far as possible, with installation adapted for optical and/or electrical wiring, air ducts and water channels.

It has proved to be linked to technical difficulties to create, in a simple man- ner, the preconditions for an interconnection of one or more ducts, associated with different discrete construction elements, and which can offer a simple and rapid interconnection of conduits, pipes etc. when coordinated construction elements are fixedly mounted at their allocated position in a foundation.

In prefabricated construction elements, in the form of inner and outer walls, it is previously known in the art to create within the construction element a ra- ceway and/or duct, where the selected duct can terminate in connection devices, such as switches, wall sockets, etc. and with connection means for the raceway or duct which offers a transition from one construction element to another construction element.

Taking into account the circumstance that the technical considerations which a person skilled in the art must do in order to be able to offer a solution to one or more set technical problems is initially on the one hand a necessary insight into the measures and/or the sequence of measures to be implemented and on the other hand a necessary selection of the means required, in view hereof the following technical problems are likely to be relevant in the evolution of the subject matter of the present invention.

Taking into account the state of the art, as described above, it is probably therefore likely to be seen as a technical problem to be able to realise the importance of, the advantages associated with and/or the technical measures and considerations which will be required in order, in a wall-related construction element, such as with one or more raceways or ducts integrated in the construction element, where a first such duct may advantageously be adaptable for and intended for air exchange, by causing to pass therethrough an air current and/or where a second such duct can advantageously be adapted for and intended for an optical and/or electric cable raceway, by permitting the passage therethrough of one or more optical and/or electrical cables and/ or the like, said construction element optionally being structured with outer panel-shaped wall portions and with, oriented between these wall portions, a frame construction adapted for the permanent support of the wall portion or wall portions, respectively, and/or with support arrangements intended for the support of the wall portion, to disclose such a prefabricated raceway or duct which will considerably facilitate a completion of a final installation, even if this extends between closely adjacent construction elements.

There resides a technical problem in being able to realise the importance of, the advantages associated with and/or the technical considerations and the deductive capacity which will be required in order to cause a selected raceway or duct to be adapted to extend along an inner wall portion and be oriented proximal its one, for instance its inner, wall portion.

There resides a technical problem in being able to realise the importance of, the advantages associated with and/or the technical considerations and the deductive capacity which will be required in order to cause said raceway or duct to be adapted to terminate at its distal and open end section, in which event said termination is to be able to related either in connection to the mu- tually divergent or directed short ends of the wall portion and/or in association with a roof portion and/or a bottom portion allocated to the construction element.

There resides a technical problem in being able to realise the importance of, the advantages associated with and/or the technical considerations and the deductive capacity which will be required in order to cause said termination to be adapted to take place either in association with a terminal box, coordinated with the open end portion of the duct or with a connectable coupling piece.

There resides a technical problem in being able to realise the importance of, the advantages associated with and/or the technical considerations and the deductive capacity which will be required in order to cause said coupling piece to be adapted to be able to unite an open end portion and/or end section of a first construction element allocated a first duct and an open end portion and/or end section of a second construction element allocated a second duct. There resides a technical problem in being able to realise the importance of, the advantages associated with and/or the technical considerations and the deductive capacity which will be required in order to cause said first and said second construction elements to be angle-oriented in relation to one another, for instance at a right angle.

There resides a technical problem in being able to realise the importance of, the advantages associated with and/or the technical considerations and the deductive capacity which will be required in order to cause in any event two, for instance in the form of, coupling boxes to be related to one and the same construction element and oriented proximal boxes allocated an adjacent and coordinated construction element.

There resides a technical problem in being able to realise the importance of, the advantages associated with and/or the technical considerations and the deductive capacity which will be required in order to cause boxes and/or coupling boxes to be related to the short ends of a construction element, which in turn is coordinable with boxes and/or coupling boxes related to an adjacent construction element.

There resides a technical problem in being able to realise the importance of, the advantages associated with and/or the technical considerations and the deductive capacity which will be required in order to cause boxes and/or coupling boxes to be related to the short end of a construction element and to be coordinable with open end portions or end sections, for channels allocated an adjacent construction element.

There resides a technical problem in being able to realise the importance of, the advantages associated with and/or the technical considerations and the deductive capacity which will be required in order to cause the construction element to display a flexurally rigid construction, exemplified by disclosing, in association with its supporting frame structure with support arrangement, the utilisation int. al. of a rigidifying triangular formed and oriented frame portion.

There resides a technical problem in being able to realise the importance of, the advantages associated with and/or the technical considerations and the deductive capacity which will be required in order to cause said construction element to be structured in order flexurally rigid to be able to be suspendable in two upper anchorage points, even if the construction element is formed with one or more window openings and/or one or more door openings.

There resides a technical problem in being able to realise the importance of, the advantages associated with and/or the technical measures which will be required in order to cause said raceway or duct, in the form of a bent thin sheet material, to be formed with in any event two opposing side portions, serving as duct-related wall or side portions, an upper portion, a roof portion, and a lower portion, a bottom portion, formed in one piece or in any event in a few mutually coordinated and fixable pieces.

There resides a technical problem in being able to realise the importance of, the advantages associated with and/or the technical measures and considerations which will be required in order to cause said two duct-related side portions, in association with lower allocated side portion sections, to be given a slightly narrower design than that of the side portions otherwise.

There resides a technical problem in being able to realise the importance of, the advantages associated with and/or the technical measures and conside- rations which will be required in order to cause said rail formed to a "U" to display a cross section provided with two right angles in order on the one hand to be able to form a planar bottom portion and on the other hand to be able to form parallel shanks, oriented at right angles thereto.

There resides a technical problem in being able to realise the importance of, the advantages associated with and/or the technical measures and considerations which will be required in order to cause the narrow formation to be gi- ven a height which to between 20 and 40 % connects to the total height of the duct.

There resides a technical problem in being able to realise the importance of, the advantages associated with and/or the technical measures and conside- rations which will be required in order to cause the value of said opposing side portions passing said roof portion to be adapted to between 20 and 40 % of the total height of the duct.

There resides a technical problem in being able to realise the importance of, the advantages associated with and/or the technical measures and considerations which will be required in order to cause the height of the narrow formation and the height of the opposing side portions passing said roof portion to be selected to be equal, or in any event substantially equal.

SOLUTION

Thus, the present invention takes as its point of departure the prior art as disclosed above and relates to a construction element formed as a wall portion, with one or more raceways or ducts, integrated in the construction element, where a first such raceway or duct can be adaptable for and intended for air exchange, by permitting the passage of an air current therethrough, and/or where a second such raceway or duct can be adaptable for and intended for a cable by permitting the passage therethrough of one or more optical and/or electrical cables and/or the like, said construction element being structured with outer panel-shaped wall portions and with frame constructions oriented between these wall portions, adapted for fixedly supporting the wall portion or the wall portions with associated support arrangements. In order to be able to resolve one or more of the above-disclosed technical problems, the present invention more specially discloses that the prior art be supplemented by causing raceways or ducts to be adapted to be able to extend in any event along the construction element and be oriented close to its one, for instance inner, wall portion.

Said raceway or duct is further to be adapted to terminate at its distal and o- pen end portions or end sections, either in association with short ends of the construction element or the wall portion facing or directed away from one an- other or in association with a roof portion and/or bottom portion allocated to the construction element and/or the wall portion.

Said termination is further adapted to be able to take place either in association with a terminal box or the like coordinate with the open end section of the duct and/or alternatively with a coupling box or piece.

Such a box and/or coupling piece is then to be able to be adapted to unite an open end portion or end section of a first duct, allocated a first construction element, and an open end portion or end section of a second duct, allocated a second construction element.

Said first and said second construction elements with associated inner wall portions can thereby be oriented at an angle to one another, for instance at a right angle.

In any event two terminal boxes or the like and/or coupling boxes are to be related to one and the same construction element and oriented in close association to an adjacent and coordinated construction element with adjacent inner wall portions. Terminal boxes and/or coupling boxes are then to be related to the short ends or short sides of a first construction element, which is coordinable with corresponding terminal boxes for an adjacent second construction element.

Terminal boxes related to one or both short ends of a construction element can also be coordinable with open end portions or end sections, for one or more raceways or ducts associated to an adjacent construction element and in association with an inner wall portion.

The construction element displays, in association with its supporting frame, construction and support arrangement, a rigidifying structure, where int. al. a triangular-configurated or oriented frame portion is inserted.

Said construction element is to be thus structured, in conjunction with its sup- port arrangement, that it can be suspendable in two upper anchorage points or -lugs.

The frame construction with its support arrangement is then, adjacent one or more window portions and/or one or more door portions, to be allocated a re- inforcement resistant to flexing and/or shearing.

As regards the structures for selected raceways or ducts, it is proposed, according to the invention, that two duct-related side portions, in association with a lower allocated side portion section, are to be allocated a slightly nar- rower form than the rest of the side portions, in which event a duct-allocated bottom portion is to be adapted to extend between said side portion sections and said opposing side portions are to be dimensioned in order upwardly to be able to pass said upper roof portion.

It is further disclosed that a separate rail, formed in a "U" in a cross section, is to be given dimensions in order closely to be able to connect to the narrow formation, in order thus to form a compatible or corresponding union. It is further disclosed that said rail, formed to a "U", is to be able to display a cross section provided with two right angles, in order thereby to be able to form a bottom portion and two parallel shanks, oriented at right angles there- to.

The upper parts of the side portions, which are adapted to pass the roof portion, are then to display an inner distance, adapted to be able to cooperate with a narrow formation, allocated a superjacent identical duct.

The narrow formation is then to be adapted to be less than the distance between the side portions with a value corresponding to the total thickness given to the parallel shanks for said rail formed to a "U".

The narrow formation can then be given a height, which, to between 20 and 40 %, will be able to connect to the total height of the duct.

The value of said opposing side portions passing said roof portion is adapted to between 20 and 40 % of the total height of the duct.

The height of the narrow formation and the height of the opposing side portions passing said roof portion should be selected to be equal, or in any event substantially equal.

ADVANTAGES

Those advantages which may principally be deemed to be characteristic of the present invention and the special significative characterising features disclosed thereby are that there have hereby been created the preconditions in order, in a wall-related construction element, with one or more raceways or ducts, integrated in the construction element, where a first such raceway or duct can be adaptable for and intended for air exchange, by permitting the passage therethrough of an air current, and/or where a second raceway or duct can be adaptable for and intended for a cable, by permitting the passage therethrough of one or more optical and/or electrical cables and/or the like, to create the preconditions to facilitate cable laying and/or connections between one or more first cables, allocated a first construction element, with correspondingly one or more second cables, allocated a second construction element.

The production of these construction elements can now be driven to a degree of finishing, which further facilitates and reduces requisite working inputs on the building site towards completion.

That which may principally be deemed to be characteristic of the present invention is disclosed in the characterising clause of appended Claim 1.

DESCRIPTION OF CURRENTLY PROPOSED EMBODIMENT

By way of introduction it should be emphasised that in the following descripti- on of one currently proposed embodiment, which displays the significative characterising features associated with the present invention and which has been clarified by the figures illustrated in the accompanying Drawings, we have selected terms and a special terminology with the intention in such instance principally of clarifying the inventive idea.

However, in this context it should be taken into consideration that expressions selected here should not be seen as restrictive exclusively to the terms utilised here and selected but it should be understood that every such selected term is to be interpreted so that it in addition encompasses all technical equivalents which function in the same or substantially the same manner, in order in such instance to be able to attain the same or substantially the same intention and/or technical effect. With reference to the accompanying Drawings, there are thus shown schematically and in detail not only the basic preconditions for the present invention but in addition the significative properties associated with the invention have been given concrete form as a result of the currently proposed embodiment described in greater detail hereinbelow.

The present invention relates to a wall-related construction element, with one or more conduit or duct constructions integrated as raceways or cable condu- its.

Thus, Figure 1 illustrates in plan view an individual modular unit with associated outer walls and inner walls, which have been provided with a number of cable conduits 2, in accordance with the principles associated with the pre- sent invention.

In Figure 1 , an inner wall, according to Figure 6, has been given reference numeral "A", while an outer wall, according to Figure 5. has been given reference numeral "B" and it is apparent that a plurality of such inner walls "A" and a plurality of such outer walls "B" are required to form the layout solution illustrated in Figure 1 and it is obvious to a person skilled in the art which constructional modifications are required to create other modules and/or layout solutions.

Figure 2 now illustrates, in front elevation, the outer wall "B", with its frame construction "B1" and its support arrangement "B2", where the support arrangement "B2" int. al. displays a reinforcing triangular form "B3" and a reinforcing "B4" around a window portion "B5".

Thus Figure 3 shows a wall element "B" in an end elevation.

Figure 4 shows the short side "B6A" in a perspective view. Figure 5 is intended to illustrate in section the building up of an outer wall element "B" while Figure 6 is intended to illustrate in perspective view the building up of an inner wall element "A".

Figure 4 illustrates a wall-related construction element "B", with one or more vertical ducts 2 wholly integrated in the construction element "B".

A first, a lowermost located horizontal, duct has been given reference nume- ra! 112'.

The first duct 112' can then be adaptable for and intended for air exchange of a space, by permitting the passage of an air current therethrough.

A second such raceway or duct 122' can then be adaptable for and intended for an information carrying and/or optical or electric cable wiring, by permitting the positioning therethrough of one or more optical and/or electrical cables and/or the like.

A third cable duct 123' is also illustrated and can be adapted for other purposes.

It should here be observed that additional raceways or ducts can be present than those illustrated here.

These ducts and/or duct constructions can be of the same or different cross sections, where such a selected cross section is illustrated in greater detail and described in Figures 7 and 8.

The horizontal ducts 112', 122' and/or 123' are adapted to be able to extend along the wall element, both the element "A" and the element "B" and be ori- ented close to their one, for example their inner, wall portion 4. (See Figure 6 and Figure 5.)

More specially the present invention discloses that said duct 112' is to be a- dapted so as to "terminate" at its distal and open end section, either in association with the mutually diverging short ends "B6a" and "B6b", respectively, of the wall portion "B" or in association with a roof portion and/or bottom portion allocated a construction element "B", embodiments which are illustrated with reference to Figure 10.

Said termination is adapted to take place either in association with a terminal box or other box 112, 122 and/or 123, coordinable with the open end of the duct or with a coupling piece oriented therein.

The boxes 112, 122 and 123 may all be of a coupling type, a cable passage type or other types.

Said boxes 112, 122 or 123 arre adapted to unite an open end section of a first duct 112' allocated to a construction element "B" and an open end sec- tion for a second duct, allocated an adjacent construction element "A".

Said first "A" and said second "B" construction elements are oriented at right angles in Figure 10, for instance at a right angle.

In any event two boxes, such as boxes 112, 133 and/or 123, are related to one and the same construction element, given the reference numeral "B" in Figure 4, and oriented proximal a (not shown) adjacent and coordinated construction element.

Boxes 112, 122 and/or 123 can advantageously be related to the short end "B6A" of a construction element "B", when this is coordinated with corresponding boxes for an adjacent construction element "A", in Figure 10. Boxes related to short ends for a construction or wall element can as an alternative be coordinable with open end portions of duct extents allocated an adjacent construction or wall element.

The construction or wall element "B" displays, in association with its supporting frame construction "B1", a rigidifying triangular configurated frame portion "B3" and is structured so as to be suspendable in two upper anchorage points "B12", "B13".

In Figure 6, said construction element "A" has been structured only with an outer panel-shaped wall portions 3, and inner panel-shaped wall portion 4 and with, oriented between these wall portions 3, 4, a frame construction "B1" adapted for fixedly supporting the wall portions, and containing support arran- gements "B2" ("B3", "B4") intended for supporting the wall portions 3, 4 and an interjacent material 5b, adapted to insulate against heat and/or sound, and where said duct construction 2, 112' and/or ducts are given an outer width "b" (See Figure 7), connecting to the selected width between divergent wall portions 3, 4 mutually facing surfaces 3a, 4a.

In this regard Figure 5 further illustrates heat and/or sound insulating layers, structured in a known manner to an outer wall, with an air gap "B7" and an antidiffusion layer "B8".

Said duct construction 20, in Figures 7 and 8, is formed with in any event two opposing and parallel side portions 21 , 22, serving as wall or side portions related to the duct 20', an upper portion 23, a roof portion, and a lower portion 24, a bottom portion.

According to the disclosures of the invention, said two channel-related side portions 21 , 22, in association with their lower side portion section 21a, 22a allocated to the side portions 21 , 22 are to be given a slightly narrower formation than that of the rest of the side portions 21 , 22.

A bottom portion 24, allocated to the duct 20', is here adapted to extend be- tween the lowermost section 21a', 22a' of said side portion section 21a, 22a.

Said opposing side portions 21 , 22 are formed planar and dimensioned so as with their uppermost section 21b, 22b to be able to pass said upper roof portion 23.

The duct construction 20 with its duct 20' is to be able to cooperate with a separate retainer unit 30, formed as discrete units or as a rail.

Such a retainer unit 30 is, according to Figure 7, to display a rail 31 formed as a "U" in cross section, with two parallel shanks 32, 33 and a bottom portion 34 interconnecting the lowermost section of the shanks.

The retainer portion 30, is according to Figure 8, to be given the dimension "a" in order tightly to be able to connect to the outer surfaces 21a, 22a of the narrow formation, given an outer dimension "c" in order thus to form a compatible or corresponding tight union.

The dimensions "a" and "c" are then to correspond to one another, with the least possible tolerance.

Said rail 31 , formed to a "U", displays a cross section provided with two right angles, in order to form a planar bottom portion 34 and at right angles thereto oriented planar shanks 32, 33 and where the bottom portion 34 is intended to be secured with means adapted herefor fixed to a substrate or a floor portion 40. Those parts 21b, 22b of the side portions 21 , 22 which are adapted to pass the roof portion 23 display an inner distance "d" adapted to be able to cooperate with a narrow formation, allocated to a superjacent duct 2', which Figure 9 is intended to illustrate.

The narrow formation with the parts 21a, 22a is adapted to be less than the distance "e" between the side portions with a value corresponding to the total thickness given to the shanks 32, 33 for said rail 31 formed to a "U".

The narrow formation is here given a height "hi", which to between 20 and 40 % connects to the total height "H" of the duct 20'.

The value of said opposing portions 21b, 22b height "h2", passing said roof portion 23 is adapted to between 20 and 40 % of the total height "H" of the duct 20'.

The height "hi" of the narrow formation and the height "h2" of the opposing side part portions, passing said roof portion 23, are selected to be equal, or in any event substantially equal.

Figure 9 shows in a perspective view the coordination of two oriented super- jacently, identical duct constructions 2, 2', where the lowermost 2 via discrete brackets 30' are fixedly connected to a substrate, such as a floor portion 40.

Figure 10 illustrates how a construction element "B" hangs in anchorage lugs "B12" and "B13" and is lowered down to support against a substrate (40).

The construction element "B" displays three parallel and horizontal duct extents 112', 122' and 123" with centrally oriented apertures 112, 122 and 123 and is adapted to cooperate with a centrally oriented construction element "A", which likewise has been provided with duct extents, however not shown, with edge-related apertures 112a, 122a and 123a and 112b, 122b and 123b. Figure 10 also illustrates the presence of apertures and/or boxes (112), (112) and (123) for the edge portion "B6b" for association to an adjacent construction element "C".

Figure 10 also illustrates anchorage lugs "A12" and "A13", respectively, in the construction element "A".

The present invention is naturally not restricted to the embodiment disclosed above by way of example but may undergo modifications within the scope of the inventive concept illustrated in the appended Claims.

Especially it should be observed that every illustrated unit and/or circuit can be combined with every other illustrated unit and/or circuit within the scope in order to be able to attain the desired technical function.

A construction element formed as a wall portion, with one or more raceways or ducts integrated in the construction element, where a first such duct can be adaptable for and intended for air exchange, by permitting the passage therethrough of an air current, and/or where a second such duct can be adaptable for and intended for a cable raceway, by permitting the passage therethrough of one or more optical and/or electrical cables and/or the like, said construction element being structured with outer panel-shaped wall portions and with a frame construction oriented between these wall portions adapted for fixedly supporting the wall portions, characterised in that a duct is adapted to be able to pass along the construction element and be oriented close to its one, for instance its inner, wall portion, that said duct is adapted to terminate at its distal and open end section, either in association with the diverging short ends of the wall portion or in association with a roof portion and/or bottom portion allocated the element, that said termination is adapted to take place either in association with a box, coordinable with the open end of the duct, or a coupling piece adapted to the duct.

2. A construction element as claimed in Claim 1 , characterised in that said coupling piece is adapted to unite an open first end section for a first duct, allocated a first construction element, and a second open end section for a second duct, allocated a second construction element.

3. A construction element as claimed in Claim 2, characterised in that said first and said second construction elements are oriented at an angle, for in- stance at a right angle.

4. A construction element as claimed in Claim 1 , characterised in that in any event two boxes are related to one and the same construction element and oriented proximal an adjacent and coordinated construction element.

5. A construction element as claimed in Claim 1 , characterised in that said boxes are related to the short ends of a construction element and coordinab- Ie with boxes for an adjacent construction element.

6. A construction element as claimed in Claim 1 , characterised in that boxes are related to the short ends of a construction element and coordinable with open end portions for ducts, allocated an adjacent construction element.

7. A construction element as claimed in Claim 1 , characterised in that the construction element displays, in conjunction with its supporting frame construction, a rigidifying construction, such as a triangular-configurated frame portion.

8. A construction element as claimed in Claim 1 , characterised in that said construction element is structured to be suspendable in two upper anchorage points.

9. A construction element as claimed in Claim 1 , characterised in that the frame construction is, adjacent a window portion and/or a door portion, provi- ded with one or more reinforcements.

10. A construction element as claimed in Claim 1 , characterised in that each one of the ducts is structured with two duct-related side portions which, in association with lower allocated side portion sections, display a slightly narrower formation than the rest of the side portions.

11. A construction element as claimed in Claim 1 or 10, characterised in that a duct-allocated bottom portion is adapted to extend between said side portion sections and that said opposing side portions are dimensioned to pass said upper roof portion.

12. A construction element as claimed in Claim 1 , 10 and/or 11 , characterised in that a rail, formed to a "U" in cross section, is given dimensions in order closely to be able to connect to the narrow formation, in order thus to form a compatible or corresponding union.

13. A construction element as claimed in Claim 1 or 12, characterised in that said rail, formed to a "U", displays a cross section provided with two right angles, in order to form a bottom portion and parallel shanks oriented at right angles thereto.

14. A construction element as claimed in Claim 12, characterised in that those parts of the side portions, which are adapted to pass the roof portion display an inner distance, adapted to be able to cooperate with a narrow formation allocated to a corresponding superjacent duct.

15. A construction element as claimed in Claim 12, characterised in that the narrow formation is adapted to be less than the distance between the side portions with a value corresponding to the total thickness given to the shanks of said rail, formed to a "U".

16. A construction element as claimed in Claim 15, characterised in that the narrower formation is given a height which to between 20 and 40 % connects to the total height of the duct.

17. A construction element as claimed in Claim 15, characterised in that the value of said opposing side portions passing said roof portion is adapted to between 20 and 40 % of the total height of the duct.

18. A construction element as claimed in Claim 17, characterised in that the height of the narrower formation and the height of the opposing side portions, passing said roof portion, are selected to be equal or in any event substanti- ally equal.
