Definitions
- the invention relates to a method of constructing a building, a building preferably constructed according to this method and wall and floor elements for use therein.
- EP 0 727 535 A1 discloses a method of constructing a partition wall, which includes providing a plurality of columns or studs, securing basic face materials to both outer sides of the studs through sound insulation materials and fixing hard gypsum sheets to the outer sides of the corresponding basic face materials, thereby providing a wall structure having fire protecting properties.
- US 5,765,333 discloses a united post and panel building system, in which a post is placed on a flooring system, a rigid foam panel, consisting of one or more layers of rigid foam bonded together using adhesives and having a shape to mate with the post, is placed next to the post, and is bonded to the post and the floor, whereafter the next post is put in place and bonded to the same panel etc.
- Furring strips may be embedded in the surfaces of the panels to allow common attachment of plasterboard on the inside of the panel wall system or siding on the outside.
- An object of the present invention is to provide an improved method of constructing a building.
- the building wall according to the invention conforms to all basic requirements of building regulations, such as compressive strength, wind resistance etc, without costly additional measures.
- large wall elements are used, such that a story high wall element completely fills the space between two adjacent upright building elements, such as columns or dividing walls. If the adjacent wall elements abut at the position of the upright building element, it is automatically covered.
- the other, preferably inner, side of the column may be covered by a separate panel to close off the space around the column.
- the wall surfaces on both sides of the building wall are flat, but for example at the position of the columns, the wall surface may be interrupted by protruding sections, or recessed sections.
- the columns may be prefabricated from wood, steel, or concrete or any combination thereof, but it is also possible to cast columns in situ by closing the space around the desired columns and to use the wall elements and panel as shuttering to form the column from structural fill-material, such as concrete.
- the walls may be formed in situ or may consist of prefab walls which are erected before the wall elements are placed.
- the walls may be processed, preferably cut, to form openings and recesses in the walls to take up doors, windows, lines and pipes etc. Since the columns and/or dividing walls take up the majority of forces in the building, the openings in the wall elements may be created as desired without deteriorating the structural integrity of the building wall. As the wall elements are hardly loaded, they are not deformed and this obviates the need for frames around windows which are normally intended to protect the glass from forces in the wall. This reduces the building costs further. Frames are only necessary for supporting movable windows. Since there is a great freedom in making openings in the walls and since these openings could be made only after constructing the walls of the building, the design of the building may be changed in a late stage of the building process. This makes the building concept very flexible.
- the wall elements can be prefabricated, with all windows, doors, lines and/or other accessories mounted in the production facility. It is even conceivable to prefabricate complete (one storey) facades or even the complete building before it is transported to the construction site.
- the invention also includes a building in accordance with claim 8.
- the covering layer includes a reinforcement layer, such as a woven mat, netting, mesh or the like, and preferably a fibre reinforced layer.
- a reinforcement layer such as a woven mat, netting, mesh or the like, and preferably a fibre reinforced layer.
- This reinforcement layer provides added strength to the wall elements in order to provide resistance against external forces, such as wind or the like.
- a reinforcement layer on the inner side of the building may also provide added strength for mounting purposes inside the house, for example for hanging objects to the walls.
- the invention also includes a wall element in accordance with claim 14.
- the wall element will generally be plane, but it may also be curved around one or more axes.
- Floors in the building are preferably made by placing and interconnecting lightweight, heat insulating floor elements, supporting them if necessary, and pouring structural fill-material, such as concrete or the like, onto the floor elements to form the floor.
- structural fill-material such as concrete or the like
- For interconnecting the floor elements use is preferably made of thin steel profile sections.
- Fig. 1 - 3 show a part of a building wall in accordance with the present invention.
- This building may be a house, but also buildings like offices or other utility buildings are conceivable.
- Figs. 1 and 2 show that the building wall comprises a skeleton including upright building elements, in this case columns 1, and wall elements 2 filling the space between the columns 1.
- the columns may consist of steel ( Fig. 1a ), wooden ( Fig. 1b ) or concrete ( Fig. 1c ) columns 1a, 1b, 1c.
- the concrete columns may be prefab columns or may be poured in situ.
- the wall elements 2 preferably have such dimensions, that they completely fill the space between the columns of one storey, so that there is only one wall element 2 between each adjacent pair of columns 1. This obviates the need for complicated (mechanical) connections between wall elements.
- Figs. 5 - 7 show the shape of one wall element 2. From Fig. 5 it is clear that the wall element 2 is rectangular. In this embodiment, the width of wall element 2 is 2.5 m, the height 3.0 m and the thickness 0.3 m, but such dimensions may of course be varied in accordance with the particular application and requirements.
- Figs. 6 and 7 show that only the part of the wall element 2 that is intended to be placed on the outside of the building wall has the dimensions as indicated above. The remainder of the wall element 2 is smaller. Due to these reduced dimensions, there is formed a rim 3 on all four edges of the wall element 2. This rim 3 is flush with the outside surface of the wall element 2 and may have a thickness of circa 60 mm. The length of the rim may for example be circa 90 mm.
- a recess 4 Adjacent to the opposite surface, intended to form the inner wall surface of the building wall, there is formed a recess 4 having substantially the same dimensions as the rim 3. This recess 4 is also formed on all four sides of the wall element 2. In this way the edges of the wall elements 2 have a stepped configuration of which middle step has a height preferably corresponding to the thickness of the columns 1, while the depth of the first and last step preferably corresponds to half the width of the projected columns 1.
- a recess having three sides of 200 mm, which is intended for accommodating the columns, as is shown in Fig. 1 .
- inserts 5 which are placed against the particular columns 1 in order to substantially fill the recess between the wall elements 2.
- a cover panel 6 may be positioned in the recesses 4 at the two adjacent edges of the wall elements 2 in order to close the recess between two wall elements, so that not only on the outside of the building wall, but also on the inside of the building wall a closed and continuous wall surface is formed.
- These closed and plane wall surfaces may be covered by covering layers 7 and 8 on the outside and inside of the building wall.
- columns which have larger dimensions, in particular a greater thickness
- several situations may be created: first, wall elements having a greater thickness are used so that again completely plane wall surfaces can be obtained, furthermore, the column and/or a covering attached thereto may project on the inside and/or outside of the wall so that the wall surface has interruptions at the position of the columns.
- Fig. 8 shows more a detailed section of the building wall at the position of a wall element 2.
- This wall element 2 forms the core of the building wall and is formed of a lightweight, heat insulating and preferably fire retarding, non-shrinking and stabile material in order to give the proper quality to the building wall.
- This material may for example be modified and pressed cardboard (e.g. as is disclosed in EP-A-1 180 564 ) or some expanded polymer, such as EPS (expanded polystyrene), for example that as offered by Unidek under the name Unidek EPS which is modified according to NEN 6065/6066 in order to obtain fire retarding properties.
- EPS expanded polymer
- the covering layer 7 on the outside of the building wall includes a first or base layer 9, preferably of modified resin mortar as is known in the art.
- This base layer 9 is an adhesive layer in order to properly attach a second or top layer 10, which may be a layer of mineral mortar for example, which has properties to resist weather conditions and other influences which may exist on the outside of a building.
- Such mineral mortar is also known in the art.
- the covering layer 8 includes a first or base layer, preferably of modified resin mortar 11, and a second or top layer 12, for example formed by plaster mortar.
- the total thickness of the covering layers 7 and 8 may be in the range of 20-30 mm, preferably 22-25 mm.
- a reinforcement layer 13, 14, which may be a woven mat, netting, mesh or the like, for example a glass or carbon fibre reinforced mesh or non-woven material.
- At least one of the reinforcement layers 13, 14, in this case the reinforcement layer 14 on the inside is positioned near the surface of the covering layer 8 in order to be at the maximum distance from the neutral bending line of the wall element 2 in order to give maximum bending resistance, for example when a wind force is exerted on a building wall.
- Another advantage of this position of the reinforcement layer 14 is that it provides strength to this layer 8 so that the wall can be used to anchor fixing means, such as nails, screws, and the like in order to attach objects to the wall.
- the expanded polystyrene material can be obtained in different qualities and in this embodiment, the wall element 2 may be formed of a standard quality, whereas the inserts 5 and cover panel 6 may be formed of higher compression material to provide additional heat insulation and strength around the columns 1 in order to obtain a substantially uniform heat-insulation quality through the entire wall.
- Fig. 9 shows a variation on the building wall of Figs. 1 and 2 , in which the wall elements 2 are curved around a vertical axis to form a circular wall.
- Fig. 2 shows a sectional side view of the building of Fig. 1 illustrating not only the structure of the building wall, but also the floors of the building. The floor structure is also shown in Fig. 4 .
- Each floor comprises floor elements 18 which are interconnected and are formed from similar material as the wall elements 2, i.e. from lightweight, insulating and fire retarding material.
- the floor elements 18 are interconnected by steel profiles 19 which may be formed from steel sheet, for example with a thickness of 1 mm.
- Recesses 20 are formed in the sides of the floor elements 18 in order to enable engagement of protruding parts of the steel profiles 19 to ensure proper attachment of the profiles to the floor elements.
- the floor elements 18 have lower rims 21 and these rims 21 of adjacent floor elements 18 are placed in abutting relationship to form a closed continuous lower surface of the floor.
- the upper part of the floor element 18 is smaller and has a trapezoid cross section.
- the floor elements 18 are connected and are supported by stays in order to resist the weight of structural fill-material, such as concrete 22, fibre reinforced resin or the like, which is poured onto the floor elements 18.
- structural fill-material such as concrete 22, fibre reinforced resin or the like, which is poured onto the floor elements 18.
- steel reinforcements 23 are placed on the floor elements 18. If necessary, inserts 25 placed in recesses that might still visible after constructing the floors 15-17.
- a floor finishing 26, a ceiling finishing 27 and the covering layer 8 on the walls are provided, preferably in the final stage.
- An embodiment of a method of constructing a building is as follows.
- a foundation in and/or on the underground if necessary at all.
- This foundation can be relatively light since the building will be much lighter than a traditional building. If a skeleton from steel or wood is used, the steel or wood columns 1 are placed on their foundation in the correct position. Inserts 5 are placed around the respective columns to create column dimensions to fit with the wall elements.
- the wall elements 2 are then placed against the columns 1, such that the rims 3 are of the wall elements 2 are placed against the outside of the columns 1 and are positioned in abutting relationship with the next wall element 2.
- Glue may be used to fix the wall elements 2 to the columns 1 and to each other, but other fixing means are conceivable.
- a cover panel 6 is positioned in the recesses 4 of the wall elements 2 to cover the last side of the column 1. In the corners of the building inserts 28 are provided to fill any remaining gap.
- the inserts 25 are mounted and the floor elements 18 are positioned on the lower inserts 25. Adjacent floor elements 18 are connected to each other by the profiles 19 and are supported on temporary supports.
- the fill-material 22 is poured on the floor elements 18, on the profiles 19, on the upper side of the wall elements 2 and the columns positioned below.
- the wall elements 2 are placed before the columns 1 are formed. Only a reinforcement for the concrete columns 1 is mounted within the recess formed by the adjacent wall elements 2.
- the cover panels 6 are mounted to form a formwork or shuttering for the concrete which is then poured in the closed recess so that a column of concrete or other structural fill-material, is formed between the wall elements 2.
- the invention provides a building method and a building that is cost effective.
- the resulting building may be so light that it can be moved in its entirety, or storeys may be built on the ground and lifted to its position afterwards.
- the energy- and maintenance cost are relatively low due to the high heat insulation and the low need for maintenance.
- the flexibility of the building is high due to the light construction which makes it easy to rebuild or extend parts of the building.
- openings may be closed again by closing or replacing a wall element and new openings may be created after completion of the building.
- the building can be demounted again and the building materials can be reused. Therefore, the building method is also environmentally friendly.
- the wall elements may be used in an burglary alarm by integrating parts thereof in the wall elements, for example light conducting fibres, or electrically conducting wires.
- floors comprising floor elements and cast concrete
- a floor from steel sections, wooden beams, an insulation layer and a cement finishing layer.
- Figs. 12-16 show a further embodiment of the building and method according to the invention.
- Fig. 12 shows a skeleton of a building, including separating or partition walls 29 and floors 30.
- the dividing walls 29 function as a lightweight building element and separate in this case individual homes which are built in a row.
- the ends of the dividing walls which are positioned at the outer side of the building more or less act as columns for the outer wall.
- the wall element 2 forms a complete façade or outside wall between two adjacent dividing walls 29 and floors 30.
- auxiliary columns 31 in this case in the form of steel sections, which are attached to the floor and ceiling 30.
- These auxiliary columns 31 may be integrated in the wall elements 2 or may be installed in the skeleton before the wall elements 2 is mounted to the skeleton.
- Figs. 13-16 show an embodiment of a wall element 2 which fits between two adjacent dividing walls 29. Therefore such wall element may be sized up to a length of 5 or 6 meters or more.
- this wall element 2 has a laminate structure including layers 32, 33, 34 which are attached, for example glued together.
- Each layer 32, 33, 34 may be formed of different parts.
- the (relative) thickness of the various layers may be varied in accordance with the respective requirements.
- the layers are each formed of different parts and the parts of the different layers being provided in an overlapping relationship so that they support each other.
- Integrated in the central layer 33 are in this case two horizontal beams 35, 36 made from wood or another suitable material such as plastic or the like.
- These horizontal beams are incorporated into the wall element 2 during the laminating process.
- These beams 35, 36 provide rigidity to the large wall element 2 and provide a means for attaching the wall element 2 to the auxiliary columns 31 and any window to the wall element 2.
- Fig. 14 it is shown that an opening 37 is already left open in the layers 32 and 34 so that after placement of the wall element 2 only layer 33 should be processed in order to finish the wall opening 37 to be able to mount the window.
- the window or window frame can be mounted to both beams 35 and 36.
- the beams 35 and 36 can also be used to attach the wall element 2 to one or more auxiliary columns 31.
- the inner wall layer 34 is recessed at the position where an auxiliary column 31 should be mounted to the wall element 2.
- the beams 35 and 36 are visible and the auxiliary column 31 can be mounted to the beams 35, 36 by means of self tapping screws or the like which are inserted through a hole in the auxiliary column 31.
- Other types of attachments are conceivable.
- the lower horizontal beam 36 has to be interrupted and cut off at the door opening.
- the doorframe could be attached to the upper horizontal beam 35.
- an auxiliary column 31 will be positioned next to a door opening in order to provide additional support for the wall element at the position of the door.
- the door frame could also be attached to an adjacent auxiliary column 31.
- the covering layer 7 or 8 on the outside or inside of the building may be provided on the wall elements 2 before the windows and/or doors are positioned in the respective openings in the wall element 2. This is advantageous as the windows and doors are preferably mounted in the wall elements 2 as late as possible in order to avoid damage to these parts. This covering layer 7 or 8 will be provided within the opening 37 up to the position where the window frame will be positioned.
- Fig. 16 shows that the recess 38 is filled with an insert 39 to cover the auxiliary column 31 and to fill the recess 38 in order to create a flush inner wall which can be covered by a continuous covering layer 8.
- the joint 40 between adjacent wall elements 2 will be filled with a filler material, preferably PUR glue which does not only fill the joint but also connects the adjacent wall elements 2 in a secure manner.
- a filler material preferably PUR glue which does not only fill the joint but also connects the adjacent wall elements 2 in a secure manner.

US 5,765,333 discloses a united post and panel building system, in which a post is placed on a flooring system, a rigid foam panel, consisting of one or more layers of rigid foam bonded together using adhesives and having a shape to mate with the post, is placed next to the post, and is bonded to the post and the floor, whereafter the next post is put in place and bonded to the same panel etc. Furring strips may be embedded in the surfaces of the panels to allow common attachment of plasterboard on the inside of the panel wall system or siding on the outside. - An object of the present invention is to provide an improved method of constructing a building.
- For this purpose the invention provides a method of constructing a building in accordance with
claim 1. - In this manner, there is provided a method which is simple and which leads to a high quality building with low building costs, but also leads to a building which can conform at least to fire safety regulations without costly additional measures. Preferably, the building wall according to the invention conforms to all basic requirements of building regulations, such as compressive strength, wind resistance etc, without costly additional measures.
- Preferably, large wall elements are used, such that a story high wall element completely fills the space between two adjacent upright building elements, such as columns or dividing walls. If the adjacent wall elements abut at the position of the upright building element, it is automatically covered. In case of a column, the other, preferably inner, side of the column may be covered by a separate panel to close off the space around the column. Preferably, the wall surfaces on both sides of the building wall are flat, but for example at the position of the columns, the wall surface may be interrupted by protruding sections, or recessed sections. The columns may be prefabricated from wood, steel, or concrete or any combination thereof, but it is also possible to cast columns in situ by closing the space around the desired columns and to use the wall elements and panel as shuttering to form the column from structural fill-material, such as concrete. In case of row houses or terraced houses in which the upright building elements are at least partially formed by dividing walls, the walls may be formed in situ or may consist of prefab walls which are erected before the wall elements are placed.
- After the (outer) building walls of the building have been constructed, the walls may be processed, preferably cut, to form openings and recesses in the walls to take up doors, windows, lines and pipes etc. Since the columns and/or dividing walls take up the majority of forces in the building, the openings in the wall elements may be created as desired without deteriorating the structural integrity of the building wall. As the wall elements are hardly loaded, they are not deformed and this obviates the need for frames around windows which are normally intended to protect the glass from forces in the wall. This reduces the building costs further. Frames are only necessary for supporting movable windows. Since there is a great freedom in making openings in the walls and since these openings could be made only after constructing the walls of the building, the design of the building may be changed in a late stage of the building process. This makes the building concept very flexible.
- As an alternative, the wall elements can be prefabricated, with all windows, doors, lines and/or other accessories mounted in the production facility. It is even conceivable to prefabricate complete (one storey) facades or even the complete building before it is transported to the construction site.
- The invention also includes a building in accordance with
claim 8. - Preferably, the covering layer includes a reinforcement layer, such as a woven mat, netting, mesh or the like, and preferably a fibre reinforced layer.
- This reinforcement layer provides added strength to the wall elements in order to provide resistance against external forces, such as wind or the like. A reinforcement layer on the inner side of the building may also provide added strength for mounting purposes inside the house, for example for hanging objects to the walls.
- The invention also includes a wall element in accordance with
claim 14. - The wall element will generally be plane, but it may also be curved around one or more axes.
- Floors in the building are preferably made by placing and interconnecting lightweight, heat insulating floor elements, supporting them if necessary, and pouring structural fill-material, such as concrete or the like, onto the floor elements to form the floor. For interconnecting the floor elements use is preferably made of thin steel profile sections.
- The invention will hereafter be elucidated with reference to the drawings, showing embodiments of the invention by way of example.

Fig. 1 - 3 show a part of a building wall in accordance with the present invention. This building may be a house, but also buildings like offices or other utility buildings are conceivable.Figs. 1 and2 show that the building wall comprises a skeleton including upright building elements, in thiscase columns 1, andwall elements 2 filling the space between thecolumns 1. As is shown inFigs. 1a, 1b and 1c the columns may consist of steel (Fig. 1a ), wooden (Fig. 1b ) or concrete (Fig. 1c ) columns 1a, 1b, 1c. The concrete columns may be prefab columns or may be poured in situ. Thewall elements 2 preferably have such dimensions, that they completely fill the space between the columns of one storey, so that there is only onewall element 2 between each adjacent pair ofcolumns 1. This obviates the need for complicated (mechanical) connections between wall elements. -
Figs. 5 - 7 show the shape of onewall element 2. FromFig. 5 it is clear that thewall element 2 is rectangular. In this embodiment, the width ofwall element 2 is 2.5 m, the height 3.0 m and the thickness 0.3 m, but such dimensions may of course be varied in accordance with the particular application and requirements.Figs. 6 and 7 show that only the part of thewall element 2 that is intended to be placed on the outside of the building wall has the dimensions as indicated above. The remainder of thewall element 2 is smaller. Due to these reduced dimensions, there is formed arim 3 on all four edges of thewall element 2. Thisrim 3 is flush with the outside surface of thewall element 2 and may have a thickness of circa 60 mm. The length of the rim may for example be circa 90 mm. - Adjacent to the opposite surface, intended to form the inner wall surface of the building wall, there is formed a
recess 4 having substantially the same dimensions as therim 3. Thisrecess 4 is also formed on all four sides of thewall element 2. In this way the edges of thewall elements 2 have a stepped configuration of which middle step has a height preferably corresponding to the thickness of thecolumns 1, while the depth of the first and last step preferably corresponds to half the width of the projectedcolumns 1. - If two
wall elements 2 are positioned next to each other, in an abutting relationship, there is formed a recess having three sides of 200 mm, which is intended for accommodating the columns, as is shown inFig. 1 . As the steel orwooden columns 1 will not exactly have these dimensions, they are provided withinserts 5 which are placed against theparticular columns 1 in order to substantially fill the recess between thewall elements 2. Acover panel 6 may be positioned in therecesses 4 at the two adjacent edges of thewall elements 2 in order to close the recess between two wall elements, so that not only on the outside of the building wall, but also on the inside of the building wall a closed and continuous wall surface is formed. These closed and plane wall surfaces may be covered by coveringlayers - If columns are used which have larger dimensions, in particular a greater thickness, several situations may be created: first, wall elements having a greater thickness are used so that again completely plane wall surfaces can be obtained, furthermore, the column and/or a covering attached thereto may project on the inside and/or outside of the wall so that the wall surface has interruptions at the position of the columns.
-
Fig. 8 shows more a detailed section of the building wall at the position of awall element 2. Thiswall element 2 forms the core of the building wall and is formed of a lightweight, heat insulating and preferably fire retarding, non-shrinking and stabile material in order to give the proper quality to the building wall. This material may for example be modified and pressed cardboard (e.g. as is disclosed inEP-A-1 180 564 ) or some expanded polymer, such as EPS (expanded polystyrene), for example that as offered by Unidek under the name Unidek EPS which is modified according to NEN 6065/6066 in order to obtain fire retarding properties. - The
covering layer 7 on the outside of the building wall includes a first orbase layer 9, preferably of modified resin mortar as is known in the art. Thisbase layer 9 is an adhesive layer in order to properly attach a second ortop layer 10, which may be a layer of mineral mortar for example, which has properties to resist weather conditions and other influences which may exist on the outside of a building. Such mineral mortar is also known in the art. - On the inside of the building wall, the
covering layer 8 includes a first or base layer, preferably of modifiedresin mortar 11, and a second ortop layer 12, for example formed by plaster mortar. The total thickness of the covering layers 7 and 8 may be in the range of 20-30 mm, preferably 22-25 mm. In this covering layers 7, 8 there is accommodated areinforcement layer reinforcement layer 14 on the inside, is positioned near the surface of thecovering layer 8 in order to be at the maximum distance from the neutral bending line of thewall element 2 in order to give maximum bending resistance, for example when a wind force is exerted on a building wall. Another advantage of this position of thereinforcement layer 14 is that it provides strength to thislayer 8 so that the wall can be used to anchor fixing means, such as nails, screws, and the like in order to attach objects to the wall. - The expanded polystyrene material can be obtained in different qualities and in this embodiment, the
wall element 2 may be formed of a standard quality, whereas theinserts 5 and coverpanel 6 may be formed of higher compression material to provide additional heat insulation and strength around thecolumns 1 in order to obtain a substantially uniform heat-insulation quality through the entire wall. -
Fig. 9 shows a variation on the building wall ofFigs. 1 and2 , in which thewall elements 2 are curved around a vertical axis to form a circular wall. -
Fig. 2 shows a sectional side view of the building ofFig. 1 illustrating not only the structure of the building wall, but also the floors of the building. The floor structure is also shown inFig. 4 . - In this case there is shown a
ground floor 15, astorey floor 16 and aroof floor 17. The structure of the floors 15 - 17 is similar, except for some differences in finishing. Each floor comprisesfloor elements 18 which are interconnected and are formed from similar material as thewall elements 2, i.e. from lightweight, insulating and fire retarding material. Thefloor elements 18 are interconnected bysteel profiles 19 which may be formed from steel sheet, for example with a thickness of 1 mm.Recesses 20 are formed in the sides of thefloor elements 18 in order to enable engagement of protruding parts of the steel profiles 19 to ensure proper attachment of the profiles to the floor elements. Thefloor elements 18 havelower rims 21 and theserims 21 ofadjacent floor elements 18 are placed in abutting relationship to form a closed continuous lower surface of the floor. The upper part of thefloor element 18 is smaller and has a trapezoid cross section. In order to form the floor, thefloor elements 18 are connected and are supported by stays in order to resist the weight of structural fill-material, such asconcrete 22, fibre reinforced resin or the like, which is poured onto thefloor elements 18. Before the fill-material 22 is poured,steel reinforcements 23 are placed on thefloor elements 18. If necessary, inserts 25 placed in recesses that might still visible after constructing the floors 15-17. A floor finishing 26, a ceiling finishing 27 and thecovering layer 8 on the walls are provided, preferably in the final stage. - An embodiment of a method of constructing a building is as follows.
- First of all, there is formed a foundation in and/or on the underground, if necessary at all. This foundation can be relatively light since the building will be much lighter than a traditional building. If a skeleton from steel or wood is used, the steel or
wood columns 1 are placed on their foundation in the correct position.Inserts 5 are placed around the respective columns to create column dimensions to fit with the wall elements. - The
wall elements 2 are then placed against thecolumns 1, such that therims 3 are of thewall elements 2 are placed against the outside of thecolumns 1 and are positioned in abutting relationship with thenext wall element 2. Glue may be used to fix thewall elements 2 to thecolumns 1 and to each other, but other fixing means are conceivable. Acover panel 6 is positioned in therecesses 4 of thewall elements 2 to cover the last side of thecolumn 1. In the corners of the building inserts 28 are provided to fill any remaining gap. Then, theinserts 25 are mounted and thefloor elements 18 are positioned on the lower inserts 25.Adjacent floor elements 18 are connected to each other by theprofiles 19 and are supported on temporary supports. After placement of thereinforcements 23, the fill-material 22 is poured on thefloor elements 18, on theprofiles 19, on the upper side of thewall elements 2 and the columns positioned below. - If in this building method concrete columns are used that are cast in situ, the
wall elements 2 are placed before thecolumns 1 are formed. Only a reinforcement for theconcrete columns 1 is mounted within the recess formed by theadjacent wall elements 2. Thecover panels 6 are mounted to form a formwork or shuttering for the concrete which is then poured in the closed recess so that a column of concrete or other structural fill-material, is formed between thewall elements 2. - From the foregoing it will be clear that the invention provides a building method and a building that is cost effective. The resulting building may be so light that it can be moved in its entirety, or storeys may be built on the ground and lifted to its position afterwards. The energy- and maintenance cost are relatively low due to the high heat insulation and the low need for maintenance. The flexibility of the building is high due to the light construction which makes it easy to rebuild or extend parts of the building. In this respect, openings may be closed again by closing or replacing a wall element and new openings may be created after completion of the building. The building can be demounted again and the building materials can be reused. Therefore, the building method is also environmentally friendly. The wall elements may be used in an burglary alarm by integrating parts thereof in the wall elements, for example light conducting fibres, or electrically conducting wires.
- As an alternative to the floors comprising floor elements and cast concrete, it is for example possible to construct a floor from steel sections, wooden beams, an insulation layer and a cement finishing layer.

Figs. 12-16 show a further embodiment of the building and method according to the invention.Fig. 12 shows a skeleton of a building, including separating orpartition walls 29 andfloors 30. The dividingwalls 29 function as a lightweight building element and separate in this case individual homes which are built in a row. The ends of the dividing walls which are positioned at the outer side of the building more or less act as columns for the outer wall. In this embodiment, thewall element 2 forms a complete façade or outside wall between twoadjacent dividing walls 29 andfloors 30. Between adjacent dividingwalls 29 there are provided one or moreauxiliary columns 31, in this case in the form of steel sections, which are attached to the floor andceiling 30. Theseauxiliary columns 31 may be integrated in thewall elements 2 or may be installed in the skeleton before thewall elements 2 is mounted to the skeleton. -
Figs. 13-16 show an embodiment of awall element 2 which fits between twoadjacent dividing walls 29. Therefore such wall element may be sized up to a length of 5 or 6 meters or more. In the embodiment shown, thiswall element 2 has a laminatestructure including layers layer central layer 33 are in this case twohorizontal beams wall element 2 during the laminating process. Thesebeams large wall element 2 and provide a means for attaching thewall element 2 to theauxiliary columns 31 and any window to thewall element 2. InFig. 14 it is shown that anopening 37 is already left open in thelayers wall element 2 onlylayer 33 should be processed in order to finish the wall opening 37 to be able to mount the window. The window or window frame can be mounted to bothbeams - As mentioned before, the
beams wall element 2 to one or moreauxiliary columns 31. InFig. 13 it is shown that theinner wall layer 34 is recessed at the position where anauxiliary column 31 should be mounted to thewall element 2. In thisrecess 38 thebeams auxiliary column 31 can be mounted to thebeams auxiliary column 31. Other types of attachments are conceivable. - If a door opening is to be made in the
wall element 2, the lowerhorizontal beam 36 has to be interrupted and cut off at the door opening. The doorframe could be attached to the upperhorizontal beam 35. Generally, anauxiliary column 31 will be positioned next to a door opening in order to provide additional support for the wall element at the position of the door. The door frame could also be attached to an adjacentauxiliary column 31. Thecovering layer wall elements 2 before the windows and/or doors are positioned in the respective openings in thewall element 2. This is advantageous as the windows and doors are preferably mounted in thewall elements 2 as late as possible in order to avoid damage to these parts. Thiscovering layer opening 37 up to the position where the window frame will be positioned. -
Fig. 16 shows that therecess 38 is filled with aninsert 39 to cover theauxiliary column 31 and to fill therecess 38 in order to create a flush inner wall which can be covered by acontinuous covering layer 8. - The joint 40 between
adjacent wall elements 2 will be filled with a filler material, preferably PUR glue which does not only fill the joint but also connects theadjacent wall elements 2 in a secure manner. - The large joint 41 between the
wall elements 2 and the dividing wall 29 (or between thewall elements 2 and thefloor 30 as shown inFig. 13 ) is filled with a sound insulating material forming a barrier against the transmittal of sound around the dividingwalls 29 orfloor 30. - From the foregoing it is apparent that the invention provides a wall element, in particular an outside wall element, which is durable, yet lightweight, fire resistant and easy to handle so that buildings may be constructed in an simple and quick manner. No extensive scaffolding is necessary, a light mobile device is sufficient to place wall elements above the ground floor.
- The invention is not limited to the embodiments shown in the drawings and described above and may be varied in different manners within the scope of the invention as defined by the appended claims. For example, the wall elements may be provided with (meandering) recesses to accommodate heating tubes of a wall and/or floor heating assembly.
