Definitions
- the invention relates to a cover system for covering an exterior wall of a building, such as a façade or a roof and a method for placing such a system.
- the invention in particular relates to a cover system that can still be installed after the construction of the building.
- a known example thereof is shown in European patent 1.618.264 .
- the cover system disclosed therein consists of plastic shells filled with thermally insulating material. With their open sides facing downward the shells are mounted on a roof.
- the shells are provided with legs which can be adjusted in height and which by means of a thread are disposed in a dedicated bush in the plastic shells. Via the legs the shells support on the roof, yet are not fixedly connected to the roof. In the placed condition the thermally insulating material forms a ballast element keeping the shells down.
- the plastic shells of the known cover system When used, the plastic shells of the known cover system are exposed to large temperature fluctuations as a result of which they shrink and expand. As the shells are placed loose onto the roof, the entire cover system - in particular at its edges - will shrink and expand relative to the roof. In case of large surfaces said shrinkage and expansion may be as much as several centimetres over the entire surface, which is undesirable.
- the present invention provides a cover system according to claims 1 to 9, and a building according to claim 10.
- Figures 1-12 show a cover system 1 according to an exemplary embodiment of the invention.
- Figure 13 shows the cover system 1 in placed condition on exterior walls of a building 9, in particular a roof 90 or a façade 91 of a building 9.
- the roof 90 is not necessarily horizontal, but may be at a slight angle of inclination, for instance at a slope for discharging precipitation.
- the cover system 1 according to the invention covers the exterior wall of the building 9 against weather influences and/or has a thermally insulating effect for the building 9 situated underneath it.
- the cover system 1 comprises a cover element 2 and a plurality of bearing supports 4, 5, 8 for supporting or bearing the cover element 2 relative to the exterior wall.
- the cover system 1 is furthermore provided with a plurality of confining elements 6, 7 for attaching the cover element 2 to or confining the cover element 2 against the plurality of bearing supports 4, 5, 8.
- the cover element 2 comprises a tray 20 made of plastic.
- the tray 20 is provided with a cover surface 21 having a substantially square outer circumference or outer edge and a substantially straight main surface H.
- the main surface H faces away from the exterior wall and/or is situated on the sight side of the cover element 2.
- the tray 20 further comprises a substantially round-going circumferential wall 22 upright from the cover surface 21.
- the cover surface 21 extends substantially parallel to the exterior wall on which the bearing supports 4, 5, 8 have been disposed and with the sight side faces away or is oriented away from the exterior wall.
- the sight side of the cover surface 21 preferably is provided with a pale colour or another suitable finishing layer for reflecting sunlight.
- the cover surface 21 comprises a surface texture that enhances grip on the cover surface 21 when it is walked on.
- the circumferential wall 22 extends from the cover surface 21 in the direction of the exterior wall and at that location forms a circumferential edge around an open side of the tray 20.
- the cover element 2 comprises a closing wall 23 made of plastic which can close off the, in figure 3 , open side of the tray 20, as shown in figure 1 .
- the closing wall 23 together with the tray 20 delimits a closed off volume within the cover element 2.
- the air volume can be kept substantially free for obtaining a substantially stagnant or ill-circulating air layer and thus augmenting the thermally insulating capacity of the cover element 2.
- the volume can at least partially or entirely be filled with thermally insulating material, such as glass wool.
- the closing wall 23 is provided with coupling elements 24A, for instance locking cams, for coupling to opposing coupling elements 24B, for instance locking openings, at the circumferential wall 22 of the tray 20.
- the cover surface 21 is in this example provided with a first parting line 25 parting the cover surface 21 into two equal parts 2A+2B and 2C+2D and a second parting line 26 extending perpendicular to the first parting line 25 and parting each of the two equal parts further into two equal parts 2A, 2B, 2C, 2D.
- the cover element 2 can be parted, for instance by sawing or cutting, or breaking - in case of a predetermined break connection or weakening in the cover surface 21 at the location of the parting lines 25, 26 -.
- the closing wall 23 is provided with corresponding parting lines 27, 28 for parting the closing wall 23 into the same parts. The result of a parting along the first parting line 25 is shown in figure 12 . Parting the cover element 2 is not always required and the cover element 2 can therefore also be supplied without parting lines 25, 26.
- Figure 3 shows that the tray 20 is provided with a rib assembly 29 which in cross bond connects the various sides of the circumferential wall 22 to each other.
- the rib assembly 29 provides the required firmness to the cover surface 21 so that it can be walked on.
- the rib assembly 29 divides the air space within the cover element 2 into individual air chambers L1, L2, L3, L4, each having its own closed off second air volume.
- the ratios between the dimensions of the air chambers parallel to the cover surface 21 and the height of the air chambers between the cover surface 21 and the closing wall 23 have been chosen such that the circulation of air within the air chambers L1-L4 is counteracted.
- the dimensions of the air chambers L1-L4 parallel to the cover surface are at least three times as large as the height of the air chambers L1-L4. Due to the limited circulation or the lack of any circulation, only minimal heat transfer can take place via the air in the air chambers L1-L4.
- the rib assembly 29 comprises a first set of twin ribs and a second set of twin ribs, wherein the ribs 29A, 29B, 29C, 29D of each set extend parallel to and on either side of the first parting line 25 and the second parting line 26, respectively.
- the ribs 29A-29D of each set of twin ribs Prior to an optional parting along one or both parting lines 25, 26, the ribs 29A-29D of each set of twin ribs are situated inside in the cover element 2.
- at least a few of the ribs 29A-D of the sets of twin ribs are situated at the exterior of the parted cover element 2 and at that location form a part of the circumferential wall 22 of the cover element 2A-2D obtained through parting.
- the closing wall 23 comprises a corresponding rib assembly 30 of which the ribs extend parallel to and on either side of the parting lines 27, 28 in the closing wall 23.
- connection lips 31, 32 are made of a resilient, flexible plastic which within its elastic range allows repeatedly bending the connection lips 31, 32 over a few millimetres.
- the free outer ends 33 of the connection lips 31, 32 can be moved within the elastic range of the plastic over a distance in a range of at least one to four millimetres at the most relative to the connection or attachment of the connection lips 31, 32 to the cover element 2.
- connection lips 31, 32 are plate-shaped and as a result flexible transverse to the surface of the plate shape, where the material thickness is small. In or parallel to the surface of the plate shape the connection lips 31, 32 are relatively rigid however.
- the first connection lip 31 is flexible in a first direction F1 substantially parallel to the cover surface 21.
- the second connection lip 32 is flexible in a second direction F2 substantially parallel to the cover surface 21 and substantially perpendicular to the first direction F1.
- the circumferential wall 22 is provided with receded circumferential wall sections 34 which relative to the outer circumference of the cover surface 21 are receded and situated at a distance from the connection lips 31, 32.
- the receded circumferential wall sections 34 preferably are situated at a distance of at least four millimetres from the connection lips 31, 32, in order to allow the bending of the connection lips 31, 32 and in particular the movement of their outer ends 33 in the direction of the receded circumferential wall sections 34. Simultaneously the receded circumferential wall sections 34 counteract that the connection lips 31, 32 move beyond the circumferential wall section 34, so that it can be prevented that the connection lips 31, 32 plastically deform beyond their elastic range.
- Figure 3 shows that at the location of the connection lips 31, 32, the closing wall 23 of the cover element 2 is provided with recesses 35 corresponding with the receded circumferential wall sections 34 in the circumferential wall 22 of the tray 20.
- the recesses 35 allow the connection lips 31, 32 to pass through from the cover surface 21 to the bearing supports 4, 5 situated on the other side of the closing wall 23.
- the cover element 2 is provided with further connection lips 31, 32 and receded circumferential wall sections 34 at each of the internal vertices which, after parting along one or both parting lines 25, 26, can be situated at the outer circumference of the thus obtained parted cover surface 21.
- the closing wall 23 is optionally provided with further recesses 36, 37 for allowing the further connection lips 31, 32 through to the bearing bases 4, 5, 8.
- FIGS. 1 , 2 and 8 show that the cover surface 21 near the corners is provided with sub-surfaces S which are situated receded relative to the main surface H in the direction of the exterior wall. Further sub-surfaces S are optionally disposed at the location of the internal vertices.
- the plurality of bearing supports comprises a first bearing support 4, a second bearing support 5 and a third bearing support 8.
- the plurality of confining elements 6, 7 comprises a first confining element 6 and a second confining element 7.
- the first bearing support 4 and the first confining element 6 are adapted for cooperating in confining the cover element 2 at a corner of the cover surface 2 which - when used on an exterior wall 90, 91 of a building 9 like in figure 13 - is situated on the exterior of the cover system 1, without being adjacent to the corner of a further confining element 2.
- the first bearing support 4 and the first confining element 6 will be further described below on the basis of the enlargement in figure 6 and the cross-section in figure 10 .
- the second bearing support 5 and the second confining element 7 are adapted for cooperating in confining the cover element 2 at a corner of the cover surface 2 which - again when used on an exterior wall 90, 91 of a building 9 like in figure 13 - is adjacent to a corner of at least one further cover element 2.
- the second bearing support 5 and the second confining element 7 will be further described below on the basis of the enlargement in figure 7 and the cross-section in figure 10 .
- the third bearing support 8 only serves to support below the centre of the cover surface 21, in order to improve the firmness, bearing power and/or capability to be walked on of the cover element 2.
- the third bearing support 8 does not cooperate with a confining element.
- the first bearing support 4 comprises a base, flange or attachment plate 40 for attaching the first bearing support 4 to the exterior wall.
- the first bearing support 4 comprises a bearing body 41 upright from the attachment plate 40 and having a bearing surface 42 oriented towards the cover element 2.
- the bearing surface 42 extends substantially parallel to the exterior wall.
- the closing wall 23 of the cover element 2 rests on the bearing surface 42 or abuts the bearing surface 42.
- the bearing surface 42 is adapted for setting or supporting the cover element 2 with the closing wall 23 at a distance from the exterior wall, for forming an air space or air cavity L5 in between the cover element 2 and the exterior wall.
- the air cavity L5 augments the insulation capacity of the cover system 1.
- the first bearing support 4 is provided with a first retaining member 43 and a second retaining member 44 for accommodating, retaining and/or positioning the first connection lip 31 and the second connection lip 32, respectively, of the cover element 2.
- the first retaining member 43 and the second retaining member 44 in this example each form an accommodation space or slot for receiving or accommodating the outer ends 33 of the respective connection lips 31, 32.
- the slots are defined by two parallel edges upright from the bearing surface 42 which edges in front of the first retaining member 43 extend parallel to the second direction F2 and in front of the second retaining member 44 extend parallel to the first direction F1.
- the slots are longer than the dimensions of the first connection lip 31 and the second connection lip 32 in the second direction F2 and the first direction F1, respectively.
- the first connection lip 31 extends up into the slot of the first retaining member 43, where the upright edges of the first retaining member 43 confine the outer end 33 of the first connection lip 31 in the first direction F1 and allow shifting thereof in the second direction F2.
- the second connection lip 32 extends up into the slot of the second retaining member 44, where the upright edges of the second retaining member 44 confine the outer end 33 of the second connection lip 32 in the second direction F2 and allow shifting thereof in the first direction F1.
- the first confining element 6 comprises a confinement member 60 and a first engagement member 61 that is fixedly connected to the confinement member 60.
- the confinement member 60 comprises a plate-shaped body extending substantially parallel to the main surface H of the cover surface 21.
- the plate-shaped body of the confinement member 60 is adapted for, in placed condition of the cover element 2 on the first bearing support 4, abutting the cover element 2 on the side of the cover surface 21 facing away from the exterior wall.
- the plate-shaped body of the confinement member 60 is disposed at the location of the sub-surface S, so that the upper side of the plate-shaped body is substantially even with the main surface H of the cover surface 21 or does not extend above it.
- the first engagement member 61 comprises a first engagement lip 62 and a second engagement lip 63, which in the placed condition extend from the confinement member 60 in the direction of the first bearing support 4, parallel to the first connection lip 31 and the second connection lip 32, respectively.
- the engagement lips 62, 63 have each been provided with internal fist teeth or first barbs 64.
- the first bearing support 4 is provided with a second engagement member 46 in the form of a first engagement space or engagement slot 47 and a second engagement space or engagement slot 48 for receiving or accommodating the first engagement lip 62 and the second engagement lip 63, respectively, of the first engagement member 61.
- the engagement slots 47, 48 have each been provided with second barbs 49 that are oppositely oriented relative to the first barbs 64.
- the second bearing support 5 is in essence an integration of four of the first bearing supports 4, wherein each first bearing support 4 forms a quadrant 5A, 5B, 5C, 5D of the integral second bearing support 5.
- the second bearing support 5 as such is suitable for simultaneously bearing or supporting a maximum of four adjacent cover elements 2 in the crossing in between them.
- the second confining element 7 is in essence an integration of four of the first confining elements 6, wherein each first confining element 6 forms a quadrant 7A, 7B, 7C, 7D of the integral second confining element 7.
- the second confining element 7 as such is suitable for simultaneously confining a maximum of four adjacent cover elements 2 in the crossing in between them.
- the second bearing support 5 comprises an attachment plate 50, an upright bearing body 51, a bearing surface 52 and a plurality of first retaining members 53 and second retaining members 54, grouped per quadrant 5A-5D for accommodating, retaining and/or positioning the first connection lips 31 and the second connection lips 32, respectively, of the adjacent cover elements 2.
- the second bearing support 5 is furthermore provided with a second engagement member 56 comprising two first engagement spaces or engagement slots 57 and two second engagement spaces or engagement slots 58.
- the engagement slots 57, 58 are provided with internal first barbs 59.
- the second confining element 7, just like the first confining element 6, comprises a confinement member 70 and a first engagement member 71 that is fixedly connected to the confinement member 70.
- the first engagement member 71 comprises two first engagement lips 72 and two second engagement lips 73.
- the engagement lips 72, 73 are provided with second barbs 74 opposite to the first barbs 59.
- the retaining members 53, 54 of the second bearing support 5 are mutually positioned such relative to the bearing surface 52 that the cover elements 2 borne on the second bearing support 5 are retained and/or positioned at a distance from each other.
- the distance between the adjacent cover elements 2 is such that the thermal expansion of one of the cover elements 2 can be set off within the intermediate space, and preferably is in the range of one to four millimetres.
- an alternative bearing support according to a third embodiment may contain two or three quadrants.
- the second bearing support 5 for obtaining such a variety is provided with predetermined break connections or parting lines 55 for parting the second bearing support 5 into two up to a maximum of four individual quadrants 5A-5D.
- the second bearing support 5 is shown after two of the four quadrants have been removed.
- the parted second bearing support 5 can be used at the outer perimeter of the cover system 1 at the location of only two adjacent cover elements 2.
- the second confining element 7 can be parted into four quadrants 7A, 7B, 7C, 7D, for instance by parting the second confining element 7 at the location of the confinement member 70 by sawing, cutting or breaking.
- the attachments plates 40, 50, 80 of the bearing supports 4, 5, 8 are provided with a series of screw holes for screwed attachment to the exterior wall or glue holes for allowing parts of a strip of glue through, which parts, after the glue has hardened, fixate the attachment plate 40 in a fixed position relative to the exterior wall.
- the bearing supports 4, 5, 8 are furthermore provided with draining channels which via the attachment plates 40, 50, 80 debouch on the exterior wall, in order to effectively drain water that ends up on or in the first bearing support 4 via the cover element 2.
- the bearing supports 4, 5, 8 are provided with reinforcement ribs between the attachment plates 40, 50, 80 and the upright bodies 41, 51, 81.
- FIG 1 a single cover system 1 is shown in placed condition and in figure 2 in exploded condition.
- the mounting direction or placement direction is schematically indicated by arrow A.
- the opposite removal direction is schematically indicated by arrow B.
- first of all a plurality of bearing supports 4, 5, 8 is placed in placement direction A on the exterior wall and positioned below the intended position of the cover element 2, in particular along the outer edge of the cover element 2 below the corners of the cover surface 21.
- the mechanic selects the first bearing support 4 or the second bearing support 5 or a parted variety thereof, for instance according to figure 8 .
- first bearing support 4 and one second bearing support 5 are shown. It will be clear that for a stable support of the cover element 2, a bearing support 4, 5 can be disposed below each corner of the cover surface 2.
- the third bearing support 8 is positioned below the centre of the cover element 2 for further supporting the centre of the cover element 2. Due to the presence of the third bearing support 8 the cover surface 2 can be walked on without the cover element 2 sagging considerably.
- the bearing supports 4, 5, 8 are fixated on the exterior wall for instance by means of a glued assembly.
- the cover element 2 After the bearing supports 4, 5 have been disposed relative to the intended position of the cover element 2 below its corners, the cover element 2, that was combined beforehand with the closing wall 23, is placed in the placement direction A onto the bearing supports 4, 5.
- the first connection lips 31 and the second connection lips 32 extend from the cover surface 21 up to the first retaining members 43, 53 and the second retaining members 44, 54, respectively, of the bearing supports 4, 5.
- the retaining members 43, 44, 53, 54 confine the outer ends 33 of the connection lips 31, 32.
- the cover element 2 is pre-positioned relative to the exterior wall of the building 9, but not yet confined or attached to the exterior wall of the building 9.
- connection lips 31, 32 beyond the retaining members 43, 44, 53, 54 in particular the portion between the retaining members 43, 44, 53, 54 and the cover surface 21, can be bent freely within the elastic range of the connection lips 31, 32. Due to the flexibility of at least a part of the connection lips 31, 32, the connection lips 31, 32 and the retaining members 43, 44, 53, 54 in mutual cooperation form flexible connections between the cover element 2 and the bearing supports 4, 5.
- the flexible connections between the first connection lips 31 and the first retaining members 43, 53 are flexible in the first direction F1.
- the flexible connections between the second connection lips 32 and the second retaining members 44, 54 are flexible in the second direction F2. Because the one of the connection lips 31, 32 can be shifted in the flexible direction F1, F2 of the other connection lip 31, 32, the flexibility of the one flexible connection is allowed or at least is not counteracted by the other flexible connection.
- the cover element 2 is able to move within the elastic range of the connection lips 31, 32, parallel to the cover surface 2 relative to the bearing supports 4, 5 and the exterior wall of the building 9 in two directions F1, F2 that are perpendicular to each other. This allows that at least a part of the thermal expansion and shrinkage of the cover element 2 in both directions F1, F2 can be set off in the flexible connections between the cover element 2 and the bearing supports 4, 5.
- the adjacent cover elements 2 in the cover system 1 are borne by the bearing supports 4, 5 at a short intermediate distance of a few millimetres relative to each other, as a result of which the thermal expansion and shrinkage in the cover system 1 can be set off per cover element 2.
- the confining elements 6, 7 are disposed on the cover element 2 in the placement direction A.
- the confinement members 60, 70 are brought into abutment with the cover element 2 from the side of the cover surface 21 facing away from the exterior wall, in particular at the location of the sub-surfaces S.
- the first engagement members 61, 71 are moved in the placement direction A along the circumferential wall 22 of the cover element 2 towards the bearing supports 4, 5 and at that location brought into engagement with the second engagement members 46, 56 of the bearing supports 4, 5.
- the engagement lips 62, 63, 72, 73, of the first engagement members 61, 71 are inserted in the placement direction A into the corresponding engagement slots 47, 48, 57, 58 of the second engagement members 46, 56, wherein the barbs 64, 74 on the engagement lips 62, 63, 72, 73 move along the oppositely oriented barbs 49, 59 of the engagement slots 47, 48, 57, 58.
- the barbs 49, 59, 64, 74 cooperate such that a movement in removal direction B opposite the placement direction A and away from the bearing support 4, 5 is blocked, is not allowed or is counteracted.
- the cover system 1 thus is substantially fixedly attached to the exterior wall of the building 9.
- the sub-surfaces S are larger than the space taken up by the confinement members 60, 70 in the sub-surfaces S, so that a movement of the cover element 2 relative to the bearing supports 4, 5 within the residual space is allowed. This is in particular of importance when the connection lips 31, 32 are designed flexible for setting off the thermal expansion or shrinkage in the cover element 2.

Description
- The invention relates to a cover system for covering an exterior wall of a building, such as a façade or a roof and a method for placing such a system.
- The invention in particular relates to a cover system that can still be installed after the construction of the building. A known example thereof is shown in European patent
1.618.264 . The cover system disclosed therein consists of plastic shells filled with thermally insulating material. With their open sides facing downward the shells are mounted on a roof. The shells are provided with legs which can be adjusted in height and which by means of a thread are disposed in a dedicated bush in the plastic shells. Via the legs the shells support on the roof, yet are not fixedly connected to the roof. In the placed condition the thermally insulating material forms a ballast element keeping the shells down. - When used, the plastic shells of the known cover system are exposed to large temperature fluctuations as a result of which they shrink and expand. As the shells are placed loose onto the roof, the entire cover system - in particular at its edges - will shrink and expand relative to the roof. In case of large surfaces said shrinkage and expansion may be as much as several centimetres over the entire surface, which is undesirable.
- Furthermore the shells according to the known cover system are heavy due to the presence of the ballast element and the mounting thereof on the roof by means of legs is time-consuming.
- Another example of a system for fixating plates to a support structure is disclosed in
FR 2950371 A1 - It is an object of the invention to provide an alternative cover system that at least partially overcomes at least one of the above-mentioned drawbacks.

Figure 13 shows a view in perspective of an embodiment of the cover system according tofigure 1 on several exterior walls of a building. -
Figures 1-12 show acover system 1 according to an exemplary embodiment of the invention.Figure 13 shows thecover system 1 in placed condition on exterior walls of abuilding 9, in particular aroof 90 or afaçade 91 of abuilding 9. Theroof 90 is not necessarily horizontal, but may be at a slight angle of inclination, for instance at a slope for discharging precipitation. Thecover system 1 according to the invention covers the exterior wall of thebuilding 9 against weather influences and/or has a thermally insulating effect for thebuilding 9 situated underneath it. - The
cover system 1 comprises acover element 2 and a plurality of bearing supports 4, 5, 8 for supporting or bearing thecover element 2 relative to the exterior wall. Thecover system 1 is furthermore provided with a plurality ofconfining elements cover element 2 to or confining thecover element 2 against the plurality of bearing supports 4, 5, 8. - As shown in
figure 2 thecover element 2 comprises atray 20 made of plastic. Thetray 20 is provided with acover surface 21 having a substantially square outer circumference or outer edge and a substantially straight main surface H. In the placed condition of thecover element 2 on the bearing supports 4, 5, 8, the main surface H faces away from the exterior wall and/or is situated on the sight side of thecover element 2. Thetray 20 further comprises a substantially round-goingcircumferential wall 22 upright from thecover surface 21. In the placed condition of thecover element 2 on the bearing supports 4, 5, 8, thecover surface 21 extends substantially parallel to the exterior wall on which the bearing supports 4, 5, 8 have been disposed and with the sight side faces away or is oriented away from the exterior wall. The sight side of thecover surface 21 preferably is provided with a pale colour or another suitable finishing layer for reflecting sunlight. Thecover surface 21 comprises a surface texture that enhances grip on thecover surface 21 when it is walked on. In the placed condition thecircumferential wall 22 extends from thecover surface 21 in the direction of the exterior wall and at that location forms a circumferential edge around an open side of thetray 20. - The
cover element 2 comprises aclosing wall 23 made of plastic which can close off the, infigure 3 , open side of thetray 20, as shown infigure 1 . Theclosing wall 23 together with thetray 20 delimits a closed off volume within thecover element 2. The air volume can be kept substantially free for obtaining a substantially stagnant or ill-circulating air layer and thus augmenting the thermally insulating capacity of thecover element 2. Alternatively the volume can at least partially or entirely be filled with thermally insulating material, such as glass wool. Theclosing wall 23 is provided withcoupling elements 24A, for instance locking cams, for coupling to opposingcoupling elements 24B, for instance locking openings, at thecircumferential wall 22 of thetray 20. - As shown in
figures 1 and2 , thecover surface 21 is in this example provided with afirst parting line 25 parting thecover surface 21 into twoequal parts 2A+2B and 2C+2D and asecond parting line 26 extending perpendicular to thefirst parting line 25 and parting each of the two equal parts further into twoequal parts parting lines cover element 2 can be parted, for instance by sawing or cutting, or breaking - in case of a predetermined break connection or weakening in thecover surface 21 at the location of theparting lines 25, 26 -. Theclosing wall 23 is provided withcorresponding parting lines closing wall 23 into the same parts. The result of a parting along thefirst parting line 25 is shown infigure 12 . Parting thecover element 2 is not always required and thecover element 2 can therefore also be supplied withoutparting lines -
Figure 3 shows that thetray 20 is provided with arib assembly 29 which in cross bond connects the various sides of thecircumferential wall 22 to each other. Therib assembly 29 provides the required firmness to thecover surface 21 so that it can be walked on. Therib assembly 29 divides the air space within thecover element 2 into individual air chambers L1, L2, L3, L4, each having its own closed off second air volume. The ratios between the dimensions of the air chambers parallel to thecover surface 21 and the height of the air chambers between thecover surface 21 and theclosing wall 23 have been chosen such that the circulation of air within the air chambers L1-L4 is counteracted. Preferably the dimensions of the air chambers L1-L4 parallel to the cover surface are at least three times as large as the height of the air chambers L1-L4. Due to the limited circulation or the lack of any circulation, only minimal heat transfer can take place via the air in the air chambers L1-L4. - In this example the
rib assembly 29 comprises a first set of twin ribs and a second set of twin ribs, wherein theribs first parting line 25 and thesecond parting line 26, respectively. Prior to an optional parting along one or bothparting lines ribs 29A-29D of each set of twin ribs are situated inside in thecover element 2. After parting along one or bothparting lines ribs 29A-D of the sets of twin ribs are situated at the exterior of theparted cover element 2 and at that location form a part of thecircumferential wall 22 of thecover element 2A-2D obtained through parting. Saidribs 29A-D ensure that, despite thecover element 2 being parted, the air chambers remain intact and closed off. Theclosing wall 23 comprises acorresponding rib assembly 30 of which the ribs extend parallel to and on either side of theparting lines closing wall 23. - As shown in
figure 3 at each corner of thecover surface 21 thecover element 2 is provided with afirst connection lip 31 and asecond connection lip 32 which, in the placed condition of thecover element 2 on the bearing supports 4, 5, 8 extend from thecover surface 21 towards the bearing supports 4, 5 disposed at the corners. Theconnection lips connection lips connection lips connection lips cover element 2. - In this example the
connection lips connection lips first connection lip 31 is flexible in a first direction F1 substantially parallel to thecover surface 21. Thesecond connection lip 32 is flexible in a second direction F2 substantially parallel to thecover surface 21 and substantially perpendicular to the first direction F1. - In this example at the location of the
connection lips circumferential wall 22 is provided with recededcircumferential wall sections 34 which relative to the outer circumference of thecover surface 21 are receded and situated at a distance from theconnection lips circumferential wall sections 34 preferably are situated at a distance of at least four millimetres from theconnection lips connection lips circumferential wall sections 34. Simultaneously the recededcircumferential wall sections 34 counteract that theconnection lips circumferential wall section 34, so that it can be prevented that theconnection lips -
Figure 3 shows that at the location of theconnection lips wall 23 of thecover element 2 is provided withrecesses 35 corresponding with the recededcircumferential wall sections 34 in thecircumferential wall 22 of thetray 20. Therecesses 35 allow theconnection lips cover surface 21 to the bearing supports 4, 5 situated on the other side of the closingwall 23. - Referring to
figures 2 ,3 and12 it is noted that optionally, for the purpose of an optional parting along the parting lines 25, 26, thecover element 2 is provided withfurther connection lips circumferential wall sections 34 at each of the internal vertices which, after parting along one or both partinglines cover surface 21. The closingwall 23 is optionally provided withfurther recesses further connection lips bearing bases - Finally
figures 1 ,2 and8 show that thecover surface 21 near the corners is provided with sub-surfaces S which are situated receded relative to the main surface H in the direction of the exterior wall. Further sub-surfaces S are optionally disposed at the location of the internal vertices. - As shown in
figures 2 and3 , the plurality of bearing supports comprises afirst bearing support 4, asecond bearing support 5 and athird bearing support 8. The plurality of confiningelements element 6 and a second confiningelement 7. Thefirst bearing support 4 and the first confiningelement 6 are adapted for cooperating in confining thecover element 2 at a corner of thecover surface 2 which - when used on anexterior wall building 9 like infigure 13 - is situated on the exterior of thecover system 1, without being adjacent to the corner of a further confiningelement 2. Thefirst bearing support 4 and the first confiningelement 6 will be further described below on the basis of the enlargement infigure 6 and the cross-section infigure 10 . Thesecond bearing support 5 and the second confiningelement 7 are adapted for cooperating in confining thecover element 2 at a corner of thecover surface 2 which - again when used on anexterior wall building 9 like infigure 13 - is adjacent to a corner of at least onefurther cover element 2. Thesecond bearing support 5 and the second confiningelement 7 will be further described below on the basis of the enlargement infigure 7 and the cross-section infigure 10 . - The
third bearing support 8 only serves to support below the centre of thecover surface 21, in order to improve the firmness, bearing power and/or capability to be walked on of thecover element 2. In this example thethird bearing support 8 does not cooperate with a confining element. - As shown in
figures 6 and9 thefirst bearing support 4 comprises a base, flange orattachment plate 40 for attaching thefirst bearing support 4 to the exterior wall. Thefirst bearing support 4 comprises a bearingbody 41 upright from theattachment plate 40 and having a bearingsurface 42 oriented towards thecover element 2. In the placed condition of thefirst bearing support 4 on the exterior wall, the bearingsurface 42 extends substantially parallel to the exterior wall. In the placed condition the closingwall 23 of thecover element 2 rests on the bearingsurface 42 or abuts the bearingsurface 42. The bearingsurface 42 is adapted for setting or supporting thecover element 2 with the closingwall 23 at a distance from the exterior wall, for forming an air space or air cavity L5 in between thecover element 2 and the exterior wall. The air cavity L5 augments the insulation capacity of thecover system 1. - As shown in
figures 6 ,9 and11 , thefirst bearing support 4 is provided with a first retainingmember 43 and a second retainingmember 44 for accommodating, retaining and/or positioning thefirst connection lip 31 and thesecond connection lip 32, respectively, of thecover element 2. The first retainingmember 43 and the second retainingmember 44 in this example each form an accommodation space or slot for receiving or accommodating the outer ends 33 of therespective connection lips surface 42 which edges in front of the first retainingmember 43 extend parallel to the second direction F2 and in front of the second retainingmember 44 extend parallel to the first direction F1. The slots are longer than the dimensions of thefirst connection lip 31 and thesecond connection lip 32 in the second direction F2 and the first direction F1, respectively. In the placed condition of thecover element 2 on thefirst bearing support 4, thefirst connection lip 31 extends up into the slot of the first retainingmember 43, where the upright edges of the first retainingmember 43 confine theouter end 33 of thefirst connection lip 31 in the first direction F1 and allow shifting thereof in the second direction F2. In a similar manner thesecond connection lip 32 extends up into the slot of the second retainingmember 44, where the upright edges of the second retainingmember 44 confine theouter end 33 of thesecond connection lip 32 in the second direction F2 and allow shifting thereof in the first direction F1. - The first confining

As shown infigure 10 theconfinement member 60 comprises a plate-shaped body extending substantially parallel to the main surface H of thecover surface 21. The plate-shaped body of theconfinement member 60 is adapted for, in placed condition of thecover element 2 on thefirst bearing support 4, abutting thecover element 2 on the side of thecover surface 21 facing away from the exterior wall. In this example the plate-shaped body of theconfinement member 60 is disposed at the location of the sub-surface S, so that the upper side of the plate-shaped body is substantially even with the main surface H of thecover surface 21 or does not extend above it. In this example thefirst engagement member 61 comprises afirst engagement lip 62 and asecond engagement lip 63, which in the placed condition extend from theconfinement member 60 in the direction of thefirst bearing support 4, parallel to thefirst connection lip 31 and thesecond connection lip 32, respectively. Theengagement lips first barbs 64. - The
first bearing support 4 is provided with asecond engagement member 46 in the form of a first engagement space orengagement slot 47 and a second engagement space orengagement slot 48 for receiving or accommodating thefirst engagement lip 62 and thesecond engagement lip 63, respectively, of thefirst engagement member 61. Theengagement slots second barbs 49 that are oppositely oriented relative to thefirst barbs 64. - As shown in
figures 7 and10 thesecond bearing support 5 is in essence an integration of four of the first bearing supports 4, wherein eachfirst bearing support 4 forms aquadrant second bearing support 5. Thesecond bearing support 5 as such is suitable for simultaneously bearing or supporting a maximum of fouradjacent cover elements 2 in the crossing in between them. In the same manner the second confiningelement 7 is in essence an integration of four of the first confiningelements 6, wherein each first confiningelement 6 forms aquadrant element 7. The second confiningelement 7 as such is suitable for simultaneously confining a maximum of fouradjacent cover elements 2 in the crossing in between them. - As the parts of the
second bearing support 5 and the second confiningelement 7 perquadrant 7A-7D substantially correspond with the parts of thefirst bearing support 4 and the first confiningelement 6, respectively, they will only be described in short below. - Just like
first bearing support 4, thesecond bearing support 5 comprises anattachment plate 50, anupright bearing body 51, a bearingsurface 52 and a plurality of first retainingmembers 53 and second retainingmembers 54, grouped perquadrant 5A-5D for accommodating, retaining and/or positioning thefirst connection lips 31 and thesecond connection lips 32, respectively, of theadjacent cover elements 2. Thesecond bearing support 5 is furthermore provided with asecond engagement member 56 comprising two first engagement spaces orengagement slots 57 and two second engagement spaces orengagement slots 58. Theengagement slots first barbs 59.

Finally the bearing supports 4, 5, 8 are provided with reinforcement ribs between theattachment plates upright bodies - The method for placing the
cover system 1 described above onto an exterior wall of abuilding 9, in particular on aroof 90 or on afaçade 91, will be further elucidated below while referring tofigures 1-13 . It is noted here that infigures 1-12 only onecover element 2 with the related bearing supports 4, 5, 8 and confiningelements cover elements 2 and the related plurality of bearing supports 4, 5, 8 and confiningelements building 9 for forming acover system 1 according tofigure 13 consisting of the plurality ofcover elements 2. Preferably thecover system 1 obtained throughseveral cover elements 2 covers a large part or substantially the entire surface of the exterior wall of thebuilding 9. The following method for placing onecover element 2 is representative of placing the plurality ofcover elements 2. - In
figure 1 asingle cover system 1 is shown in placed condition and infigure 2 in exploded condition. The mounting direction or placement direction is schematically indicated by arrow A. The opposite removal direction is schematically indicated by arrow B. In order to achieve the placed condition according tofigure 1 , first of all a plurality of bearing supports 4, 5, 8 is placed in placement direction A on the exterior wall and positioned below the intended position of thecover element 2, in particular along the outer edge of thecover element 2 below the corners of thecover surface 21. Depending on the positions of the corners of thecover surface 21 within thecover system 1, in particular depending on the adjacency of said corners to further coverelements 2, the mechanic selects thefirst bearing support 4 or thesecond bearing support 5 or a parted variety thereof, for instance according tofigure 8 . Infigures 1 and2 only onefirst bearing support 4 and onesecond bearing support 5 are shown. It will be clear that for a stable support of thecover element 2, abearing support cover surface 2. Optionally thethird bearing support 8 is positioned below the centre of thecover element 2 for further supporting the centre of thecover element 2. Due to the presence of thethird bearing support 8 thecover surface 2 can be walked on without thecover element 2 sagging considerably. The bearing supports 4, 5, 8 are fixated on the exterior wall for instance by means of a glued assembly. - After the bearing supports 4, 5 have been disposed relative to the intended position of the
cover element 2 below its corners, thecover element 2, that was combined beforehand with the closingwall 23, is placed in the placement direction A onto the bearing supports 4, 5. In the placed condition of thecover element 2 on the bearing supports 4, 5 thefirst connection lips 31 and thesecond connection lips 32 extend from thecover surface 21 up to thefirst retaining members second retaining members members connection lips cover element 2 is pre-positioned relative to the exterior wall of thebuilding 9, but not yet confined or attached to the exterior wall of thebuilding 9. - At least a part of the

elements cover element 2 at the location of the bearing supports 4, 5 is confined between theconfinement members elements elements cover system 1 thus is substantially fixedly attached to the exterior wall of thebuilding 9. - In the first and second directions F1, F2, the sub-surfaces S are larger than the space taken up by the
confinement members cover element 2 relative to the bearing supports 4, 5 within the residual space is allowed. This is in particular of importance when theconnection lips cover element 2. - The method described above for placing one
cover element 2 can be repeated for a plurality ofcover elements 2. The bearing supports 4, 5, 8 can be disposed percover element 2. However, it is more efficient to dispose the bearing supports 4, 5, 8 for a plurality ofcover elements 2 simultaneously, and not until after that placing thecover elements 2 one after the other on the bearing supports 4, 5, 8. The confiningelements cover element 2. Here as well it is more efficient however to dispose the confiningelements cover elements 2. The invention makes disposing the confiningelements cover elements 2 is already retained in position on the bearing supports 4, 5 prior to this. - If so desired the
cover elements 2 can be parted along the parting lines 25, 26 into two or more parts, wherein theconnection lips internal rib assembly 29 and halfway thecircumferential wall 22 offer the opportunity of also disposing bearing supports 4, 5 at theparts 2A-2D of the partedcover element 2. - The above description is included to illustrate the operation of preferred embodiments of the invention and not to limit the scope of the invention. Starting from the above explanation many variations that fall within the scope of the present invention as defined by the appended claims will be evident to an expert.
