Abstract
The invention concerns an installation floor with a layer comprising a plurality of substantially rectangular floor panels (1) which are made of mineral hydraulically bonded material and are loosely disposed in a predetermined grid pattern on a stand arrangement consisting of individual vertically adjustable supports (3), spaces (4) being left for cables and pipes of the installation. The supports (3) comprise a cup (10) which, optionally via a part provided with a surface complementary to said cup (10), supports an associated floor panel (1) in the region of a corner thereof. The floor panels (1) are rebated in a stepped manner according to a set laying pattern, which optionally comprises given floor panels (1) supported in a removable manner.
The floor panels (1) are laid such that their joins overlap at the connection between the rebates, floor panels (1) supported in a removable manner being supported only by adjacent floor panels (1).
The floor panels (1) are laid such that their joins overlap at the connection between the rebates, floor panels (1) supported in a removable manner being supported only by adjacent floor panels (1).
Description
., - Surface-installation Floor The invention relates to a surface-installation - floo~ according to the preamble of Claim 1.
In cavity floors which comprise a multiplicity of essentially rectangular, identical floor panels which are arranged in a layer, in a predetermined grid pattern, on a support arrangement, spaces for receiving installation line, being left in the process, certain degrees of loading typically result in bending, which can lead to the joints between the floor panels gaping. This has an adverse effect on the appearance.
EP-A-0 641 903 discloses a surface-installation floor which comprises floor panels which are provided on the periphery with a stepped rebate and are laid on supports in chessboard form such that the stepped rebate, which projects on all sides, is arranged at the bottom.
The interspaces present in the chessboard-like arrangement are taken up in this case by floor panels which, rather than having a peripheral rebate, have plant~r side walls and rest on the projecting stepped rebates of the adjacent rebated floor panels.
Consequently, although continuous joints between the floor panels are avoided, a floor of this type requires two sorts of floor panels, the non-rebated floor panel having to be of a thickness which allows it to withstand the required loading as well, while the rebated floor pane:Ls have to be designed in a correspondingly thicker manner in order to achieve a planar surface, since they addit:ionally have to support the non-rebated floor panels from beneath.
In large rooms of, for example, lengths and widths of more than 15 m, standard evenness and angle tolerances of the subfloor, for example of a concrete floor, which can be compensated are presently not more than approximately 45 mm (standardized). These relatively large deviations mean that metallic supports according to EP-A-0 641 903, which have a fleece-like shank with an integrally designed foot and a screwed-in screw-bolt with an abutment disc, pose problems as regards vertical alignment, especially since these supports each support two ,~butting rebated floor panels together, as a result of which the horizontal levelling, which is important for the uniform abutment of cavity-floor panels or other floor abutments, is also adversely effected.
The object of the invention is to provide a surface-installation floor according to the preamble of Claim 1 which, despite the avoidance of continuous joint:s, manages with just one type of floor panel, which is not excessively thick, for a certain laying pattern, it being possible for evenness tolerances of the subfloor to be readily compensated for.
This object is achieved in accordance with the characterizing part of Claim 1.
Further configurations of the invention can be gathered from the following description and the subc:Laims.
The invention is explained in more detail hereinbelow with reference to exemplary embodiments illustrated schematically in the attached drawings, in which:

The surface-installation floor illustrated in Figure 1 comprises a layer made up of a multiplicity of ident:ical, rectangular or, as is illustrated, in particular sc~are floor panels 1, which are arranged in a predetermined grid pattern, in accordance with grid lines 2', 2" which intersect at right angles, on a support arrangement formed from supports 3, receiving spaces 4 for installation lines being left in the process.
The floor panels 1 are provided at the four corners with bevels 5 at 45O and are also provided with a stepped rebate 6 on the periphery. As a result, one surface 7' of the floor panel 1 is greater than the grid ~imPnsion~ by half the rebate width, on all sides, while the opposite, smaller surface 7" of the floor panel 1 is smalLer than the grid ~;men~ion, by half the rebate width, on all sides.
In practice, the bevels 5 intersect the grid-line cross 2', 2" at 45O. The bevels 5 thus generally extend over a relatively small corner region, such that the centre of the bevels 5 are arranged so as to correspond to the grid pattern.
In both directions of the grid-line cross 2', 2", the floor panels 1 are arranged in an interlocking manner, with overlapping joints, with the larger surface 7' and the smaller surface 7" alternately directed upwards. This avoids bending under loading and resultant gaping of the joints between the floor panels 1, as a resuLt of which the overall appearance is one of a continuous surface.
In this context, the floor panels 1 with stepped rebat:es 6 projecting at the bottom are expediently supported by in each case one support 3 adjacent to their four corners, while the floor panels 1 which are borne or can be taken up directly, with stepped rebates 6 projecting at the top, are only supported by the floor pane:Ls 1 with the stepped rebates 6 projecting at the bottom .
First of all, in the manner of a chessboard, every second floor panel 1, namely all those with the large surface 7' upwards, can readily be taken up, without any disruptive effect, for subsequent installation or inspection purposes. If required, it is also then possible for the rest of the floor panels 1 to be taken up.
Since the floor panels 1 which, with reference to the laying pattern of Figure 1, are identical are beve:Lled at 45O at all four corners and have a stepped reba-te 6 on all sides, the panels being laid in an interlocking manner with overlapping joints, there are no occurrences of bending under loading and resulting gaping of the joints between the floor panels 1, with the result that the impression of a closed surface is achieved.
The surface-installation floor illustrated in Figure 5 likewise comprises a multiplicity of essentially square floor panels 1 which, in this embodiment, all have, at one side edge, a stepped rebate 6' which is directed to one side and, at the other three side edges, a stepped rebate 6" which is directed to the other side, the stepped rebates 6', 6" being on the periphery in each case and having the same width at all locations.
The floor panels 1 are laid in a line such that, in each line 8a, 8b, 8c, 8d, the stepped rebate 6' which is located at only one side edge is located in each case at the same side of the floor panels 1, this side running transversely with respect to the longitudinal direction of the line. The floor panels 1 are laid in a line with the stepped rebate 6' alternately upwards and downwards, the stepped rebate 6' in the respective line 8a, 8b, 8c, 8d being located at the side border which is remote from the stepped rebate 6' of the next floor panel 1 of this line. The floor panels 1 of one line rest with their stepped rebates 6" which project at the top, in the longitudinal direction of the line, on the stepped rebates 6" which project at the bottom, and extend in the longitudinal direction, of the floor panels 1 of adjacent lines 8a, 8c. In the transverse direction with respect to the respective line 8a, 8b, 8c, 8d, the stepped rebates 6" which project at the top, in the longitudinal direction, of the floor panels 1 of the respective line rest on the stepped rebates 6" which project at the bottom, in the longitudinal direction, of the floor paneLs 1 of the same line.
The floor panels 1 with stepped rebates 6"
projecting at the bottom on three sides are expediently supported by in each case one support 3 adjacent to two corners between two adjacent sides with stepped rebates 6" projecting at the bottom, while the floor panels 1 which can be taken up in a line, with stepped rebates 6"
projecting at the top, are supported by the floor panels 1 wit:h the stepped rebates 6" which project at the bottom on three sides.
The floor panels 1 of the lines 8b, 8d can be taken up directly in line form.
Provided in the embodiment illustrated in Figure 7 is a multiplicity of essentially scIuare floor panels 1 which all comprise two sc~uare panel parts which are offset by a predetermined distance with respect to one another in the diagonal direction, as a result of which a top stepped rebate 6' is formed at two adjacent side edges and a bottom stepped rebate 6" is formed at the other two adjacent side edges, the stepped rebates 6', 6"
being on the periphery in each case and having the same width at all locations. The panel parts are of the same size and usually, but not necessarily, of the same thickness (which also applies to the two embodiments described above).
The floor panels 1 are laid in a flush manner such that the respectively top stepped rebate 6', which runs over two side borders, of one floor panel 1 rests on the respectively bottom stepped rebates 6", which run over two side borders, of two floor panels 1 which are localed adjacent to the side borders with the stepped rebale 6'. On the side which is to be adjoined by the next row of floor panels 1 in each case, the bottom stepped rebates 6" of a row of floor panels 1 which has been laid in the manner described above form a continuous abutment strip for this next row of floor panels 1.
In this case, the floor panels 1 are expediently supported in each case by one support 3 adjacent to a corner between the two sides on which the stepped rebate 6" which projects at the bottom is located.
In accordance with requirements, the different laying patterns according to Figures 1, 5 and 7 can be used one beside the other in sub-regions; for example, the embodiment in Figure 5 can be used in halls or corr:Ldors and the embodiments of Figures 1 and 7 can be used in adjoining rooms. Depending on requirements, they may also be used together with floor sub-regions which are formed by means of pourable screed (supported or unsupported). In particular, regions which can be taken up in line form according to Figure 5 are provided within fixed regions laid according to Figure 7, while, if appropriate, regions according to Figure 1 adjoin the latter. In transition regions between different laying patterns or other regions, it is necessary to insert floor panels which have been adapted correspondingly on the circumference.
If appropriate, it is possible to form a plurality of blocks of supported floor panels 1 which are stabilized in the horizontal direction by border supports 20.
The border supports 20 may be configured, for example, in accordance with the embodiment illustrated in Figures 9 and 10. Provided for the purpose is an angle 21 which is reinforced via struts 22 and is provided in its upright leg 21a with two vertical slots 23 which serve for receiving an adjustment plate 24 in a vertically adjustable manner. Said adjustment plate has two welded-on sc:rew-bolts 25 which extend through the slots 23 and are fastened on the leg 21a via nuts 26. The essentially horizontal leg 21b of the angle 21 is provided, adjacent to its border which is remote from the leg 21a, with sunken feet 27 and, on the opposite border, which is adjac:ent to the leg 21a, with one or more relatively stiff spring elements 28, for example made of hard rubber. The horizontal leg 21b also has a bore 29 for fastening the angle 21 in the subfloor by means of a screw and a connector (not illustrated).
The border supports 20, or the adjustment plates 24 thereof, absorb the horizontal forces from the floor panels 1 supported by them in the horizontal direction and dissipate these forces into the subfloor, with the resu]t that it is neither necessary for room-boundary walls to do this nor is there any risk, when taking up take--up floor panels 1, of displacement of floor panels 1 of that part of the respective laying pattern which is not taken up, which would result in the latter floor pane]Ls not maintaining their position and in all the associated floor panels 1 having to be relaid at a later stage rather than just those which have been taken up being reinserted.
Border supports 20 are also expedient in order to define an expansion joint, for example, every 15 to 20 m.
As can be seen from Figure 3, the stepped rebates 6, 6', 6" are each expediently provided with bevels 9 or rounded sections at the edges of the respective horizontal rebate section 6a.
It is also possible, as is illustrated in Figure 4, for the stepped rebate 6, 6', 6" of the floor panel l to run obliquely, in particular one of the two oblique surf ces 6b of the stepped rebate 6, 6', 6" forming a largl_r angle with the horizontal than the other oblique surfilce 6c, with the result that, in contrast to the embodiment of Figure 3, abutment takes place only in the region of the horizontal rebate section 6a.
A design corresponding to Figure 3 or 4 serves to ensure an improved flux of forces and to avoid point moun1ing between a load-bearing floor panel l and a floor pane:L l which is borne by the latter.
The floor panels l are expediently in one piece, it being possible for them to be produced as cuboids, whereupon the stepped rebates 6, 6', 6" are produced by milling. However, the floor panels may also produced by adhe:;ively bonding two panel parts of appropriate ~;mensions.
The floor panels l consist of mineral material which is bound by a hydraulic binder, in particular by calcium sulphate a-hemihydrate, and are, in particular, fibrous gypsum panels, although it is also possible to use other building materials such as calcium-hydrosilicate-bound building materials.
If appropriate, the floor panels l may be adhesively bonded to one another in the region where they interlock.
Installations which serve as workplace power supplies, for example electricity feeders, may be inserted in openings which are provided or made in appropriate floor panels l.
In order that the supports 3, despite evenness tole~ances, can be levelled in a simple manner, with the result that even large tolerances of a subfloor are accommodated without difficulty, the supports 3 comprise a spherical section lO which, either directly or via a part provided with a surface which is complementary to the ,pherical section 10, supports an associated floor panei! 1 adjacent to a corner of the latter, which means at the same time that each support 3 supports just one floor panel 1, rather than a plurality of floor panels 1 at thLe same time, with the result that floor panels 1, or sides of the latter, which are not supported by the supports 3 are merely borne by other floor panels 1. At the same time, this results in a lesser degree of fitting outlay in relation to supports which are arranged at the abutt:ing corners of the floor panels so as to bear a plurality of the latter.
The spherical section 10 may be located on any part of the support 3, for example its foot, its shank or a separate abutment part can bear the spherical section 10 or be designed as such. If the associated floor panel 1 is supported via a part provided with a surface which is complementary to the spherical ~ection 10, then said part is preferably moveable with respect to the spherical section 10 in order thus to be capable of automatic alignment with respect to the plane of the floor panel 1.
The support 3 illustrated in Figure 11 comprises a foot 11 with a central cutout 12 for receiving an insertable shank casing 13 and the spherical section 10 with planar top side 14. The foot 11 expediently has a top side 15 running conically towards the cutout 12 and a large, low-level standing surface at the outer border.
Although the foot 11 in the exemplary embodiment illustrated is round in plan view, it may likewise be, for example, square or hexagonal in plan view. It consists of a mineral, hydraulically set material based, in particular, on calcium sulphate a-hemihydrate.
The shank casing 13 expediently consists of paperboard or a comparable material serving as shuttering and is inserted into the cutout 12, the insertion depth being selected in accordance with requirements. For this purpose, it is expedient if there is a friction fit between the cutout 12 and the shank casing 13, with the result that the latter remains at the desired level without any further auxillary means. A scale 16 which, for example, has been printed on may serve as an aid for retaining the desired insertion depth.
The spherical section 10 is placed on the shank casing 13 with its arched part downwards and likewise consists of a mineral, hydraulically set material based, in particular, on calcium sulphate ~-hemihydrate and may be provided with a central funnel 17.
First of all, the shank casing 13 may essentially be filled with mortar, whereupon the spherical section 10 is p:Laced in position, with the result that some of the mortt~r can penetrate into the funnel 17. Thereafter, precise vertical and horizontal levelling can take place before the mortar has set.
The shank casing 13 may also be a hollow cylinder made of a mineral, hydraulically set building material based, in particular, on calcium sulphate ~-hemihydrate and, moreover, may have a wall thickness which is sufficient for absorbing the envisaged loading without being filled with mortar. Instead of a shank casing 13, it is also possible to use a solid-cylindrical shank. In this case, a cutout is provided at its top end for the purpose of receiving the spherical section 10 such that the latter can be rotated and tilted, this cutout, if appropriate, receiving a mortar bed for the spherical section 10 or else a bowl-like insert made, for example, of ~ footstep-sound-insulating material such as a plast:ic. If desired, the shank and the spherical section 10 can be fixedly connected to one another via mortar introduced into the funnel 17.
A plate made of a footstep-sound-insulating material such as a plastic or the like can be fastened on the planar top side 14 of the spherical section 10.
The support 3 illustrated in Figure 12 comprises a column-like foot 11, which may comprise a disc-like basic element lla and an attachment llb. The basic elem~_nt lla and attachment llb are expediently round discs of preferably the same diameter (although it is also possible to use discs of different shapes, for example polygonal discs) and consist of mineral, hydraulically set material, for example based on gypsum 5 and, in particular, on calcium sulphate ol-hemihydrate, the hardness of which is advantageous in this case. Basic elements lla can be added up to the planned height.
The attachment llb may bear at the top a plate-like footstep-sound-insulation means 34 made of an 10 elasl omeric material. Moreover, the attachment llb bears a sleeve 29 which is provided with an external thread and may be provided at the top with a transverse wall, which butts against the top side of the footstep-sound-insulation means 34.
Screwed onto the sleeve 29 is a spherical section 10 which is provided with an internal thread in its peripheral parts and, by virtue of rotation with respect to the sleeve 29, is vertically adjustable with respect to the attachment llb. The spherical section 10 expediently has a peripheral, possibly corrigated bead 35 for better actuation.
The support 3 illustrated in Figure 13 comprises a foot 11 with a central cutout 12 which is provided with a thread and is intended for receiving a screw-in, hollow-cylindrical shank 13 having a corresponding thread, and further comprises a spherical section 10 with a pltmar surface 14. The spherical section 10 rests with its ~;pherical surface on the correspondingly bevelled top border of the shank 13 and is thus moveable with respect to the latter, with the result that the planar surface 14 on the top side of the spherical section 10 can be readily aligned horizontally. A footstep-sound insulation can be placed in position on the planar surface 14 or integrated in the latter.
The foot 11 is provided at the top with a peripheral flange 36, which results in better handling for vertical levelling. The foot 11 and shank 13 are metal parts, as is also preferably the case for the spherical section 10, although it is also possible for the latter to be made of a mineral, hydraulically set building material. In particular, these components are cast:ings with the possible exception of the shank 13, which, in particular, may also be rolled.
In the embodiment illustrated in Figure 14, the spherical section 10 has its spherical section directed upwards and is inserted into the shank 13 by way of a stub-like continuation 37. The spherical section 10 bears a co~lplementary attachment 38 which has a planar top side 39 and can be moved with respect to the spherical section 10, with the result that this attachment can be readily aligned horizontally with the planar top side 39 by virtue of a floor panel 1 butting against the latter.
The support 3 illustrated in Figures 15 to 17 comprises a column-like shank 40 which comprises two shan]c elements 40a, 40b and bears the spherical section 10, which may bear a part 41 which is arched correspondingly at the bottom and can be moved on the spherical section 10. These parts all have a circular cross-section and consist of mineral, hydraulically set material based, for example, on gypsum and, in part:icular, on calcium sulphate a-hemihydrate, the hardness of which is advantageous in this case.
Connection to a subfloor may take place by means of adhesive or mortar.
The two parts 10 and 41 may be arranged beneath or above the shank elements 4Oa, 4Ob.
The spherical section 10 may also be designed integrally with the shank element 40b.
The shank element 40a, which is provided with an axia:Lly extending, central, circular-cylindrical cutout 42, has, on the side which faces the shank element 40b, three helically wound turns 43 which are arranged one behind the other in a circumferential direction, extend over 1200, are of the same pitch and start and end at the same level. As far as the turns 43 are concerned, the shank element 40b is of corresponding design, but has a central guide stub 44 which is received by the opening 42, t:his resulting in inner guidance. The shank elements 40a, 40b are thus vertically adjustable with respect to one another by way of rotation.
The turns 43 preferably have a rough surface, whi ch, in particular, may be designed as sawtoothed stepping .
The shank elements 40a, 40b may, if appropriate, be enclosed by a sheathing, for example made of plastic, which has been used as shuttering.
According to those exemplary embodiments of supports 3 which are illustrated in Figures 18 to 20, these supports each comprise a foot 11 which is made of mineral material bound by a hydraulic binder, in particular of calcium sulphate a-hemihydrate, and is provided with a central, vertically extending cutout 12, and further comprise two metallic parts which can be screwed with respect to one another for vertical adjustment and of which one part is inserted into the cutout 12 of the foot 11 and is supported by the latter, while the other part supports the associated floor panel 1, one of the two parts forming the spherical section 10.
Provided according to Figure 18 is a screw 19 which is produced in one piece, for example by rolling, has ,~ hat 47, designed integrally therewith, and is in engagement with a nut 18, designed as an abutment nut. At the lop, the nut 18 has a flange 48 which rests on the foot 11, while the cutout 12 receives the nut 18. The flange 48 may have noses 49 which are bent in the direction of the foot 11 and are received by cutouts 50 adjoining the cutout 12 laterally, in order thus to form a rot:ation-prevention means for the nut 18. The hat 47 of the screw 19 is arched slightly upwards, in order to form the spherical section 10 by way of this arched surface.
The screw 19 is expediently secured against rotalion by a rotation-prevention means 52, as is illustrated in Figure 21. This means 52 is an approximately U-shaped clamp with two arms 53 which can CA 02227406 l998-0l-20 be pushed apart from one another in the outward direction and delimit a cutout 54 corresponding to the internal diameter of the thread of the screw 19. The rotation-prevention means 52 is inserted into the thread turn of the screw 19 adjacent to the nut 18, an upright section 55 being useful.
The hat 47 may also be produced separately and, if appropriate, so as to project laterally to a desired extent with respect to the screw 19 and may be fastened on the screw 19, for example, by being pressed thereon.
According to Figure 19, the screw 19 is provided with the spherical section 10, which in this case conslitutes a round head for the screw 19, while a disc 56 with a central section 57 which is arched corresponding to the round head is supported on the latter. The disc 56 iS retained on the round head by means of plugs 58 SO as to be pivotable and moveable on all sides, and it has a peripheral border region 59 for supporting an associated floor panel 1.
According to Figure 20, the flange 48 which is fastened at the bottom of the nut 18 comprises the spherical section 10, which is inserted into the cutout 12, with the result that the nut 18 iS pivotable on all sides. The screw 19 has a planar abutment surface 60 for an associated floor panel 1, it being possible for the abutrnent surface 60 to be formed by a countersunk head (as illustrated) or by a planar hat, disc or the like.
The radius of curvature of the spherical section 10 when the latter supports a floor panel 1 directly is prefe!rably selected such that, with a mAximllm permissible inclination of the support 3 of, for example, 10%, the spherical section 10 still butts, at the border, approximately tangentially against the floor panel 1.
As is indicated in Figure 18, it is possible, for fireproofing reasons, to arrange around support 3 which comprise metallic parts, a protective ring 61 made of mineral material, for example of the same material as that of the foot 11, the protective ring 61 being divicled, in the longitudinal direction of the support 3, into two halves which are set up on the subfloor around the installed support 3, bearing a floor panel 1, with the :result that a relatively small gap remains between 5 the top side of the protective ring 61 and the floor pane:L 1.
In cavity floors which comprise a multiplicity of essentially rectangular, identical floor panels which are arranged in a layer, in a predetermined grid pattern, on a support arrangement, spaces for receiving installation line, being left in the process, certain degrees of loading typically result in bending, which can lead to the joints between the floor panels gaping. This has an adverse effect on the appearance.
EP-A-0 641 903 discloses a surface-installation floor which comprises floor panels which are provided on the periphery with a stepped rebate and are laid on supports in chessboard form such that the stepped rebate, which projects on all sides, is arranged at the bottom.
The interspaces present in the chessboard-like arrangement are taken up in this case by floor panels which, rather than having a peripheral rebate, have plant~r side walls and rest on the projecting stepped rebates of the adjacent rebated floor panels.
Consequently, although continuous joints between the floor panels are avoided, a floor of this type requires two sorts of floor panels, the non-rebated floor panel having to be of a thickness which allows it to withstand the required loading as well, while the rebated floor pane:Ls have to be designed in a correspondingly thicker manner in order to achieve a planar surface, since they addit:ionally have to support the non-rebated floor panels from beneath.
In large rooms of, for example, lengths and widths of more than 15 m, standard evenness and angle tolerances of the subfloor, for example of a concrete floor, which can be compensated are presently not more than approximately 45 mm (standardized). These relatively large deviations mean that metallic supports according to EP-A-0 641 903, which have a fleece-like shank with an integrally designed foot and a screwed-in screw-bolt with an abutment disc, pose problems as regards vertical alignment, especially since these supports each support two ,~butting rebated floor panels together, as a result of which the horizontal levelling, which is important for the uniform abutment of cavity-floor panels or other floor abutments, is also adversely effected.
The object of the invention is to provide a surface-installation floor according to the preamble of Claim 1 which, despite the avoidance of continuous joint:s, manages with just one type of floor panel, which is not excessively thick, for a certain laying pattern, it being possible for evenness tolerances of the subfloor to be readily compensated for.
This object is achieved in accordance with the characterizing part of Claim 1.
Further configurations of the invention can be gathered from the following description and the subc:Laims.
The invention is explained in more detail hereinbelow with reference to exemplary embodiments illustrated schematically in the attached drawings, in which:

The surface-installation floor illustrated in Figure 1 comprises a layer made up of a multiplicity of ident:ical, rectangular or, as is illustrated, in particular sc~are floor panels 1, which are arranged in a predetermined grid pattern, in accordance with grid lines 2', 2" which intersect at right angles, on a support arrangement formed from supports 3, receiving spaces 4 for installation lines being left in the process.
The floor panels 1 are provided at the four corners with bevels 5 at 45O and are also provided with a stepped rebate 6 on the periphery. As a result, one surface 7' of the floor panel 1 is greater than the grid ~imPnsion~ by half the rebate width, on all sides, while the opposite, smaller surface 7" of the floor panel 1 is smalLer than the grid ~;men~ion, by half the rebate width, on all sides.
In practice, the bevels 5 intersect the grid-line cross 2', 2" at 45O. The bevels 5 thus generally extend over a relatively small corner region, such that the centre of the bevels 5 are arranged so as to correspond to the grid pattern.
In both directions of the grid-line cross 2', 2", the floor panels 1 are arranged in an interlocking manner, with overlapping joints, with the larger surface 7' and the smaller surface 7" alternately directed upwards. This avoids bending under loading and resultant gaping of the joints between the floor panels 1, as a resuLt of which the overall appearance is one of a continuous surface.
In this context, the floor panels 1 with stepped rebat:es 6 projecting at the bottom are expediently supported by in each case one support 3 adjacent to their four corners, while the floor panels 1 which are borne or can be taken up directly, with stepped rebates 6 projecting at the top, are only supported by the floor pane:Ls 1 with the stepped rebates 6 projecting at the bottom .
First of all, in the manner of a chessboard, every second floor panel 1, namely all those with the large surface 7' upwards, can readily be taken up, without any disruptive effect, for subsequent installation or inspection purposes. If required, it is also then possible for the rest of the floor panels 1 to be taken up.
Since the floor panels 1 which, with reference to the laying pattern of Figure 1, are identical are beve:Lled at 45O at all four corners and have a stepped reba-te 6 on all sides, the panels being laid in an interlocking manner with overlapping joints, there are no occurrences of bending under loading and resulting gaping of the joints between the floor panels 1, with the result that the impression of a closed surface is achieved.
The surface-installation floor illustrated in Figure 5 likewise comprises a multiplicity of essentially square floor panels 1 which, in this embodiment, all have, at one side edge, a stepped rebate 6' which is directed to one side and, at the other three side edges, a stepped rebate 6" which is directed to the other side, the stepped rebates 6', 6" being on the periphery in each case and having the same width at all locations.
The floor panels 1 are laid in a line such that, in each line 8a, 8b, 8c, 8d, the stepped rebate 6' which is located at only one side edge is located in each case at the same side of the floor panels 1, this side running transversely with respect to the longitudinal direction of the line. The floor panels 1 are laid in a line with the stepped rebate 6' alternately upwards and downwards, the stepped rebate 6' in the respective line 8a, 8b, 8c, 8d being located at the side border which is remote from the stepped rebate 6' of the next floor panel 1 of this line. The floor panels 1 of one line rest with their stepped rebates 6" which project at the top, in the longitudinal direction of the line, on the stepped rebates 6" which project at the bottom, and extend in the longitudinal direction, of the floor panels 1 of adjacent lines 8a, 8c. In the transverse direction with respect to the respective line 8a, 8b, 8c, 8d, the stepped rebates 6" which project at the top, in the longitudinal direction, of the floor panels 1 of the respective line rest on the stepped rebates 6" which project at the bottom, in the longitudinal direction, of the floor paneLs 1 of the same line.
The floor panels 1 with stepped rebates 6"
projecting at the bottom on three sides are expediently supported by in each case one support 3 adjacent to two corners between two adjacent sides with stepped rebates 6" projecting at the bottom, while the floor panels 1 which can be taken up in a line, with stepped rebates 6"
projecting at the top, are supported by the floor panels 1 wit:h the stepped rebates 6" which project at the bottom on three sides.
The floor panels 1 of the lines 8b, 8d can be taken up directly in line form.
Provided in the embodiment illustrated in Figure 7 is a multiplicity of essentially scIuare floor panels 1 which all comprise two sc~uare panel parts which are offset by a predetermined distance with respect to one another in the diagonal direction, as a result of which a top stepped rebate 6' is formed at two adjacent side edges and a bottom stepped rebate 6" is formed at the other two adjacent side edges, the stepped rebates 6', 6"
being on the periphery in each case and having the same width at all locations. The panel parts are of the same size and usually, but not necessarily, of the same thickness (which also applies to the two embodiments described above).
The floor panels 1 are laid in a flush manner such that the respectively top stepped rebate 6', which runs over two side borders, of one floor panel 1 rests on the respectively bottom stepped rebates 6", which run over two side borders, of two floor panels 1 which are localed adjacent to the side borders with the stepped rebale 6'. On the side which is to be adjoined by the next row of floor panels 1 in each case, the bottom stepped rebates 6" of a row of floor panels 1 which has been laid in the manner described above form a continuous abutment strip for this next row of floor panels 1.
In this case, the floor panels 1 are expediently supported in each case by one support 3 adjacent to a corner between the two sides on which the stepped rebate 6" which projects at the bottom is located.
In accordance with requirements, the different laying patterns according to Figures 1, 5 and 7 can be used one beside the other in sub-regions; for example, the embodiment in Figure 5 can be used in halls or corr:Ldors and the embodiments of Figures 1 and 7 can be used in adjoining rooms. Depending on requirements, they may also be used together with floor sub-regions which are formed by means of pourable screed (supported or unsupported). In particular, regions which can be taken up in line form according to Figure 5 are provided within fixed regions laid according to Figure 7, while, if appropriate, regions according to Figure 1 adjoin the latter. In transition regions between different laying patterns or other regions, it is necessary to insert floor panels which have been adapted correspondingly on the circumference.
If appropriate, it is possible to form a plurality of blocks of supported floor panels 1 which are stabilized in the horizontal direction by border supports 20.
The border supports 20 may be configured, for example, in accordance with the embodiment illustrated in Figures 9 and 10. Provided for the purpose is an angle 21 which is reinforced via struts 22 and is provided in its upright leg 21a with two vertical slots 23 which serve for receiving an adjustment plate 24 in a vertically adjustable manner. Said adjustment plate has two welded-on sc:rew-bolts 25 which extend through the slots 23 and are fastened on the leg 21a via nuts 26. The essentially horizontal leg 21b of the angle 21 is provided, adjacent to its border which is remote from the leg 21a, with sunken feet 27 and, on the opposite border, which is adjac:ent to the leg 21a, with one or more relatively stiff spring elements 28, for example made of hard rubber. The horizontal leg 21b also has a bore 29 for fastening the angle 21 in the subfloor by means of a screw and a connector (not illustrated).
The border supports 20, or the adjustment plates 24 thereof, absorb the horizontal forces from the floor panels 1 supported by them in the horizontal direction and dissipate these forces into the subfloor, with the resu]t that it is neither necessary for room-boundary walls to do this nor is there any risk, when taking up take--up floor panels 1, of displacement of floor panels 1 of that part of the respective laying pattern which is not taken up, which would result in the latter floor pane]Ls not maintaining their position and in all the associated floor panels 1 having to be relaid at a later stage rather than just those which have been taken up being reinserted.
Border supports 20 are also expedient in order to define an expansion joint, for example, every 15 to 20 m.
As can be seen from Figure 3, the stepped rebates 6, 6', 6" are each expediently provided with bevels 9 or rounded sections at the edges of the respective horizontal rebate section 6a.
It is also possible, as is illustrated in Figure 4, for the stepped rebate 6, 6', 6" of the floor panel l to run obliquely, in particular one of the two oblique surf ces 6b of the stepped rebate 6, 6', 6" forming a largl_r angle with the horizontal than the other oblique surfilce 6c, with the result that, in contrast to the embodiment of Figure 3, abutment takes place only in the region of the horizontal rebate section 6a.
A design corresponding to Figure 3 or 4 serves to ensure an improved flux of forces and to avoid point moun1ing between a load-bearing floor panel l and a floor pane:L l which is borne by the latter.
The floor panels l are expediently in one piece, it being possible for them to be produced as cuboids, whereupon the stepped rebates 6, 6', 6" are produced by milling. However, the floor panels may also produced by adhe:;ively bonding two panel parts of appropriate ~;mensions.
The floor panels l consist of mineral material which is bound by a hydraulic binder, in particular by calcium sulphate a-hemihydrate, and are, in particular, fibrous gypsum panels, although it is also possible to use other building materials such as calcium-hydrosilicate-bound building materials.
If appropriate, the floor panels l may be adhesively bonded to one another in the region where they interlock.
Installations which serve as workplace power supplies, for example electricity feeders, may be inserted in openings which are provided or made in appropriate floor panels l.
In order that the supports 3, despite evenness tole~ances, can be levelled in a simple manner, with the result that even large tolerances of a subfloor are accommodated without difficulty, the supports 3 comprise a spherical section lO which, either directly or via a part provided with a surface which is complementary to the ,pherical section 10, supports an associated floor panei! 1 adjacent to a corner of the latter, which means at the same time that each support 3 supports just one floor panel 1, rather than a plurality of floor panels 1 at thLe same time, with the result that floor panels 1, or sides of the latter, which are not supported by the supports 3 are merely borne by other floor panels 1. At the same time, this results in a lesser degree of fitting outlay in relation to supports which are arranged at the abutt:ing corners of the floor panels so as to bear a plurality of the latter.
The spherical section 10 may be located on any part of the support 3, for example its foot, its shank or a separate abutment part can bear the spherical section 10 or be designed as such. If the associated floor panel 1 is supported via a part provided with a surface which is complementary to the spherical ~ection 10, then said part is preferably moveable with respect to the spherical section 10 in order thus to be capable of automatic alignment with respect to the plane of the floor panel 1.
The support 3 illustrated in Figure 11 comprises a foot 11 with a central cutout 12 for receiving an insertable shank casing 13 and the spherical section 10 with planar top side 14. The foot 11 expediently has a top side 15 running conically towards the cutout 12 and a large, low-level standing surface at the outer border.
Although the foot 11 in the exemplary embodiment illustrated is round in plan view, it may likewise be, for example, square or hexagonal in plan view. It consists of a mineral, hydraulically set material based, in particular, on calcium sulphate a-hemihydrate.
The shank casing 13 expediently consists of paperboard or a comparable material serving as shuttering and is inserted into the cutout 12, the insertion depth being selected in accordance with requirements. For this purpose, it is expedient if there is a friction fit between the cutout 12 and the shank casing 13, with the result that the latter remains at the desired level without any further auxillary means. A scale 16 which, for example, has been printed on may serve as an aid for retaining the desired insertion depth.
The spherical section 10 is placed on the shank casing 13 with its arched part downwards and likewise consists of a mineral, hydraulically set material based, in particular, on calcium sulphate ~-hemihydrate and may be provided with a central funnel 17.
First of all, the shank casing 13 may essentially be filled with mortar, whereupon the spherical section 10 is p:Laced in position, with the result that some of the mortt~r can penetrate into the funnel 17. Thereafter, precise vertical and horizontal levelling can take place before the mortar has set.
The shank casing 13 may also be a hollow cylinder made of a mineral, hydraulically set building material based, in particular, on calcium sulphate ~-hemihydrate and, moreover, may have a wall thickness which is sufficient for absorbing the envisaged loading without being filled with mortar. Instead of a shank casing 13, it is also possible to use a solid-cylindrical shank. In this case, a cutout is provided at its top end for the purpose of receiving the spherical section 10 such that the latter can be rotated and tilted, this cutout, if appropriate, receiving a mortar bed for the spherical section 10 or else a bowl-like insert made, for example, of ~ footstep-sound-insulating material such as a plast:ic. If desired, the shank and the spherical section 10 can be fixedly connected to one another via mortar introduced into the funnel 17.
A plate made of a footstep-sound-insulating material such as a plastic or the like can be fastened on the planar top side 14 of the spherical section 10.
The support 3 illustrated in Figure 12 comprises a column-like foot 11, which may comprise a disc-like basic element lla and an attachment llb. The basic elem~_nt lla and attachment llb are expediently round discs of preferably the same diameter (although it is also possible to use discs of different shapes, for example polygonal discs) and consist of mineral, hydraulically set material, for example based on gypsum 5 and, in particular, on calcium sulphate ol-hemihydrate, the hardness of which is advantageous in this case. Basic elements lla can be added up to the planned height.
The attachment llb may bear at the top a plate-like footstep-sound-insulation means 34 made of an 10 elasl omeric material. Moreover, the attachment llb bears a sleeve 29 which is provided with an external thread and may be provided at the top with a transverse wall, which butts against the top side of the footstep-sound-insulation means 34.
Screwed onto the sleeve 29 is a spherical section 10 which is provided with an internal thread in its peripheral parts and, by virtue of rotation with respect to the sleeve 29, is vertically adjustable with respect to the attachment llb. The spherical section 10 expediently has a peripheral, possibly corrigated bead 35 for better actuation.
The support 3 illustrated in Figure 13 comprises a foot 11 with a central cutout 12 which is provided with a thread and is intended for receiving a screw-in, hollow-cylindrical shank 13 having a corresponding thread, and further comprises a spherical section 10 with a pltmar surface 14. The spherical section 10 rests with its ~;pherical surface on the correspondingly bevelled top border of the shank 13 and is thus moveable with respect to the latter, with the result that the planar surface 14 on the top side of the spherical section 10 can be readily aligned horizontally. A footstep-sound insulation can be placed in position on the planar surface 14 or integrated in the latter.
The foot 11 is provided at the top with a peripheral flange 36, which results in better handling for vertical levelling. The foot 11 and shank 13 are metal parts, as is also preferably the case for the spherical section 10, although it is also possible for the latter to be made of a mineral, hydraulically set building material. In particular, these components are cast:ings with the possible exception of the shank 13, which, in particular, may also be rolled.
In the embodiment illustrated in Figure 14, the spherical section 10 has its spherical section directed upwards and is inserted into the shank 13 by way of a stub-like continuation 37. The spherical section 10 bears a co~lplementary attachment 38 which has a planar top side 39 and can be moved with respect to the spherical section 10, with the result that this attachment can be readily aligned horizontally with the planar top side 39 by virtue of a floor panel 1 butting against the latter.
The support 3 illustrated in Figures 15 to 17 comprises a column-like shank 40 which comprises two shan]c elements 40a, 40b and bears the spherical section 10, which may bear a part 41 which is arched correspondingly at the bottom and can be moved on the spherical section 10. These parts all have a circular cross-section and consist of mineral, hydraulically set material based, for example, on gypsum and, in part:icular, on calcium sulphate a-hemihydrate, the hardness of which is advantageous in this case.
Connection to a subfloor may take place by means of adhesive or mortar.
The two parts 10 and 41 may be arranged beneath or above the shank elements 4Oa, 4Ob.
The spherical section 10 may also be designed integrally with the shank element 40b.
The shank element 40a, which is provided with an axia:Lly extending, central, circular-cylindrical cutout 42, has, on the side which faces the shank element 40b, three helically wound turns 43 which are arranged one behind the other in a circumferential direction, extend over 1200, are of the same pitch and start and end at the same level. As far as the turns 43 are concerned, the shank element 40b is of corresponding design, but has a central guide stub 44 which is received by the opening 42, t:his resulting in inner guidance. The shank elements 40a, 40b are thus vertically adjustable with respect to one another by way of rotation.
The turns 43 preferably have a rough surface, whi ch, in particular, may be designed as sawtoothed stepping .
The shank elements 40a, 40b may, if appropriate, be enclosed by a sheathing, for example made of plastic, which has been used as shuttering.
According to those exemplary embodiments of supports 3 which are illustrated in Figures 18 to 20, these supports each comprise a foot 11 which is made of mineral material bound by a hydraulic binder, in particular of calcium sulphate a-hemihydrate, and is provided with a central, vertically extending cutout 12, and further comprise two metallic parts which can be screwed with respect to one another for vertical adjustment and of which one part is inserted into the cutout 12 of the foot 11 and is supported by the latter, while the other part supports the associated floor panel 1, one of the two parts forming the spherical section 10.
Provided according to Figure 18 is a screw 19 which is produced in one piece, for example by rolling, has ,~ hat 47, designed integrally therewith, and is in engagement with a nut 18, designed as an abutment nut. At the lop, the nut 18 has a flange 48 which rests on the foot 11, while the cutout 12 receives the nut 18. The flange 48 may have noses 49 which are bent in the direction of the foot 11 and are received by cutouts 50 adjoining the cutout 12 laterally, in order thus to form a rot:ation-prevention means for the nut 18. The hat 47 of the screw 19 is arched slightly upwards, in order to form the spherical section 10 by way of this arched surface.
The screw 19 is expediently secured against rotalion by a rotation-prevention means 52, as is illustrated in Figure 21. This means 52 is an approximately U-shaped clamp with two arms 53 which can CA 02227406 l998-0l-20 be pushed apart from one another in the outward direction and delimit a cutout 54 corresponding to the internal diameter of the thread of the screw 19. The rotation-prevention means 52 is inserted into the thread turn of the screw 19 adjacent to the nut 18, an upright section 55 being useful.
The hat 47 may also be produced separately and, if appropriate, so as to project laterally to a desired extent with respect to the screw 19 and may be fastened on the screw 19, for example, by being pressed thereon.
According to Figure 19, the screw 19 is provided with the spherical section 10, which in this case conslitutes a round head for the screw 19, while a disc 56 with a central section 57 which is arched corresponding to the round head is supported on the latter. The disc 56 iS retained on the round head by means of plugs 58 SO as to be pivotable and moveable on all sides, and it has a peripheral border region 59 for supporting an associated floor panel 1.
According to Figure 20, the flange 48 which is fastened at the bottom of the nut 18 comprises the spherical section 10, which is inserted into the cutout 12, with the result that the nut 18 iS pivotable on all sides. The screw 19 has a planar abutment surface 60 for an associated floor panel 1, it being possible for the abutrnent surface 60 to be formed by a countersunk head (as illustrated) or by a planar hat, disc or the like.
The radius of curvature of the spherical section 10 when the latter supports a floor panel 1 directly is prefe!rably selected such that, with a mAximllm permissible inclination of the support 3 of, for example, 10%, the spherical section 10 still butts, at the border, approximately tangentially against the floor panel 1.
As is indicated in Figure 18, it is possible, for fireproofing reasons, to arrange around support 3 which comprise metallic parts, a protective ring 61 made of mineral material, for example of the same material as that of the foot 11, the protective ring 61 being divicled, in the longitudinal direction of the support 3, into two halves which are set up on the subfloor around the installed support 3, bearing a floor panel 1, with the :result that a relatively small gap remains between 5 the top side of the protective ring 61 and the floor pane:L 1.
