The invention relates to a building composed of outside wall components, roof components, and optionally ceiling components, at least the outside wall components being made double-walled, and having panels which are connected to one another with the formation of at least one cavity in the outside wall component via spacers with a distance from one another, in the cavity between the panels of the outside wall component there being a means for supplying heat to the cavity of the outside wall components.
WO 02/22975 A1 for a generic building also mentions the idea of using the intermediate space between the panels of the wall components which are made in at least two layers to heat or cool the building by connecting the cavities to the corresponding heating and cooling means.
DE 198 01 165 C proposes providing a heating means in the hollow wall. The heating means should have a plate which adjoins the wall to be heated over a large area.
CH 687 884 A discloses providing installation channels within a hollow wall.
The object of the invention is to develop the building known from WO 02/22975 A1 such that the passage of heat through the panels forming the outside walls is at least reduced.
This object is achieved as claimed in the invention in a building of the initially mentioned type in that the means for supplying heat is located exclusively in the lower area of the outside wall components.
Other preferred and advantageous embodiments of the building as claimed in the invention are the subject matter of the dependent claims.
Since in the building as claimed in the invention the wall components which form the outside walls and/or the inside walls are equipped with a heating means, it is possible to route so much heat to the cavity in the wall components that heat losses are reduced or compensated. It is not primarily intended here that the heat supply by the heating means located in the cavity of the wall components be chosen to be so large that the building is also heated.
In the invention the heating components of the heating means are located in the lower area of the cavity of the outside wall components, its being preferred if the heating components are located in the area of the “sills” on which the outside wall components stand vertically.
Other details, features and advantages of the invention follow from the description below of preferred embodiments of the invention with reference to the drawings.
a shows a detail of a wall component of one modified embodiment on an enlarged scale,
b shows another embodiment of a wall component and
c shows a third embodiment in the area of the sill of the wall component,
A building as claimed in the invention in the embodiment shown in the figures consists of outside wall components, inside wall components, ceiling components and/or roof components, the components being made at least twin-walled. Each of the components of the building as claimed in the invention accordingly consists of at least one outer panel, at least one inner panel and spacers such as spacer blocks or spacer strips which connect the panels of the components with a distance from one another.
The panels comprising the outside wall components, inside wall components, ceiling components, and/or roof components of a building as claimed in the invention consist of wood material, particle board being emphasized. Within the framework of the invention, particle board, in the form of OSB board (multilayer board) which is produced from long, slender, oriented wood chips with a predetermined shape and thickness and a binder (OSB board), is preferred.
The wood chips in the outside layers can be oriented parallel to the panel length or width. The wood chips in the middle layer can be arranged randomly, or are oriented generally at a right angle to the wood chips of the outside layer.
For the invention, the particle board can also consist of long, slender, oriented wood chips with a predetermined shape and thickness which are connected with a binder into USB board (single layer board) in which the orientation of the wood chips over the entire thickness of the panel is essentially uniform. A transversely placed middle layer, as in the above described OSB board, is not provided in this particle board.
The spacers such as strips or blocks can consist of wood material, and for example can be particle board which has been cut accordingly. The spacers (strips or blocks) can also be solid wood parts.
It is preferred if the inner and outer panels of the components as claimed in the invention are connected to the spacers by glues. Screws, nails and the like can also be provided which are however used mainly to hold the components as claimed in the invention together until the glue layer has set.
The ceilings and roof need not necessarily be cooled or heated in the invention.
It is advantageous if a wall component is made in two parts, one part being a sill component which is located on the lower end of a wall component. The sill component and wall component become a unit after installation, and the heating for the house can be integrated in the sill component.
In the case of heating components in the area of the sill components heat conduction takes place in the intermediate spaces of the wall components by rising and falling air columns.
The flow temperature of the heating component (water-filled pipe of metal or plastic or composites) can be for example 40° to 75° C. The choice of the flow temperature also determines the height of the air column, i.e. the wall can be heated to the desired height, for example a height of 1 m, 1.5 m, or 2 m.
A building which is provided with the features as claimed in the invention can be heated via the outer and/or inner walls.
It is advantageous in the invention that it is gravity heating without additional means for circulating the air (for example, fans). The pipe which is provided in the building as claimed in the invention as a heat-releasing component can be made with additional heat conduction sheets or rods in order to enlarge the heat-releasing surface.
As
The lower of the two outside wall components 10 which are placed on top of one another in
The sill 20 has an essentially U-shaped cross sectional shape with a lower, horizontally aligned crosspiece 21 and two legs 22 which project to the top. The panels 11 of the lower outside wall component 10 rest vertically on the ends of the legs 22 of the sill 20, which ends point up.
In the area of the cavity which is open to the top in the sill 20 there is a heating means 30 (
The surfaces 35 of the supports 33 which point up can be bevelled, as shown in
In the embodiment as shown in
b shows an embodiment in which one leg 22′ of the sill 20 can be removed so that the pipe 32 of the heating means 31 can be inserted from the side into the recesses 36′ which are open to the side in the supports 33 even when a wall component 10 has already been erected on the sill 20. This allows for example pipes 32 to be installed or replaced not only subsequently, but also allows repairs to be made.
c shows one modification of the embodiment from
The pipes 32 of the heating means 31 can be ribbed pipes and/or pipes with external attachments in the form of rods, disks or plates in order to enlarge the heat-releasing area of the pipes 32. If the supports 33 are metal, they also act as enlargements of the heat-releasing surface of the pipes 32 of the heating means 31.
Heat is released through the heating rod 31 into the cavity 13 between the panels 11 of the wall components 10. In doing so the amount of released heat is preferably chosen such that the heat losses which would occur when heat emerges to the outside from the interior of a building composed of wall components 10 are compensated. Therefore the K value of a wall formed from the wall components 10 is so to speak reduced to 0.
What is analogous can also be applied to cases in which the outside temperature is higher than the temperature within a building which is composed of wall components 10, in which case there is a cooling means. Such a cooling means is preferably located in the area of the top end of a wall of a building composed of wall components 10.
The supports 33 can consist of any material, it is preferable if the supports 33 are formed from plastic or the like or from wood material.
Instead of a pipe 32 through which a heating medium flows, the heating rod 31 can also be an electrical resistance heating rod or wire.
In order to not to hinder the flow of heated air indicated by the arrow 2 in
As
Thus it is ensured that the flow of heat released by the heating means 30 which is located in the area of the sill 20 through the cavities 13 of the outside wall components 10 into the cavity of the roof components 50 is not hindered by the ceiling components 40. In this way it is possible so to speak to isolate the entire outer shell of a building as claimed in the invention such that heat losses through the outside shell of the building formed by the wall components 10, ceiling components 40 and the roof components 50 are prevented.
FIGS. 10 to 13 show schematically one corner of a building as claimed in the invention with outside wall components 10, a ceiling component 40 and a roof component 50. FIGS. 10 to 13 show that the cavities in the outside wall components 10 can communicate with the cavities in the roof components 50 since there are the corresponding recesses 41 and 52 in the edge area of the ceiling component 40 and roof component 50.
In the embodiment of a sill which is equipped with a heating device 30, shown in
The beam 60 for its part is supported by a profile strip 62 which has a crosspiece 63 and two legs projecting up from it. The legs 64 via projections 65 (ribs or knobs which run lengthwise) adjoin the lateral surfaces of the beam 60 which runs lengthwise. The profile strip 62 rests on a component which can be placed under it via an insulating layer 60.
The sill indicated in
Application examples for an arrangement of this type of sill with a heating means 30 are shown in FIGS. 15 to 17.
In summary, one embodiment of the invention can be described as follows:
A building consists of wall components 10 and ceiling component 40 made twin-walled as well as roof components 50 likewise made twin-walled. The wall components 10 with their lower ends rest on sills 20 in which there is a heating means 30. The heating means 30 releases as much heat to the cavity 13 between the plates 11 of the wall components 10 and the ceiling components 40 as well as the roof components 50 that the heat which is lost by heat passage through the outer shell of the building is at least partially, especially entirely, compensated.
As a result, the heat passage through the outside walls and/or the roof components 50 of the building is reduced to zero or nearly so.
