Description

According to a first aspect, the present disclosure relates to a positioning and fastening device for positioning and fastening a wall element to a floor for realising a wall of a building.
According to a second aspect, the present disclosure relates to an assembly comprising a positioning and fastening device according to the first aspect of the present disclosure.
According to a third aspect, the present disclosure relates to a building comprising a floor, a positioning and fastening device according the first aspect of the present disclosure and a wall comprising wall elements.
According to a fourth aspect, the present disclosure relates to a method for realising an assembly according to the second aspect of the present disclosure.
Known walls of buildings may be provided as a brick wall comprising bricks that are held together by for instance glue or mortar. These known walls may be fixated to the floor using for instance glue or mortar. Alternatively, known walls may be connected to a floor through anchors or be placed on the floor without the use of further elements. A drawback of these ways of connecting a wall to a floor is that it may be relatively difficult to achieve a predetermined position of the wall relative to the floor.
An objective of the present disclosure is to provide a device and a method for positioning and fastening a wall element, preferably a modular wall element, to a floor for realising a wall of a building overcoming the drawback indicated.
The objective is realised by providing a positioning and fastening device comprising:

a fastening arrangement arranged for fastening to said wall element;
an elongated base extending in a longitudinal direction, said elongated base comprising a fastening arrangement receiving space arranged for partly receiving said fastening arrangement, wherein said fastening arrangement receiving space is dimensioned such that said fastening arrangement is movable in said fastening arrangement receiving space;
a clamping element pivotably connected to said elongated base and arranged such that in a first position of said clamping element said fastening arrangement is movable in said fastening arrangement receiving space and in a second position of said clamping element said fastening arrangement is clamped between said clamping element and said elongated base, wherein said clamping element is arranged for, in use, being brought in said second position by said wall element.

By providing the fastening arrangement and the fastening arrangement receiving space according to the present disclosure, a wall element that, in use, is fastened to the fastening arrangement may be positioned relatively accurately relative to the floor by moving the fastening arrangement in the fastening arrangement receiving space. This is beneficial for allowing to achieve a predetermined position of the wall element relative to the floor. Once the predetermined position of the wall element is achieved the wall element may be clamped, by the clamping element and the elongated base, for maintaining the wall element in the predetermined position.
An additional advantage of the positioning and fastening device according to the first aspect is that there is no need for using glue or mortar for fixating the wall element to the floor. This is beneficial for allowing the wall element to be removed from the floor without the need for removing glue or mortar between the wall element and the floor which may cause damage to the wall element. Since there is no need for using glue or mortar, the wall element may be recovered with no, or only relative limited damage, thereby allowing re-use of the wall element for realising another wall.
It is beneficial if said elongated base is provided with a clamping element receiving space and said clamping element is arranged such that in said first position said clamping element is removable from said elongated base. This is beneficial for allowing exchange of the clamping element for instance when the clamping element is damaged without the need for replacing further elements of the positioning and fastening arrangement such as the elongated base.
Preferably, said elongated base and said clamping element are arranged such that in said second position of said clamping element a supporting surface of said elongated base and a supporting surface of said clamping element are provided in a virtual flat plane for supporting said wall element. Such a virtual flat plane is preferred for realising a relative good distribution of pressure between the wall element and the positioning and fastening device. A relative good pressure distribution is attractive for realising a relative robust clamping while reducing the risk of damaging either the positioning and fastening device or the wall element.
It is advantageous if said elongated base and/or said fastening arrangement are made from extruded profiles, preferably extruded profiles made from aluminium. Extruded profiles are beneficial in this regard for realising a relative straight wall in a practical manner.
It is beneficial if said fastening arrangement receiving space extends in said longitudinal direction of said elongated base for allowing said fastening arrangement to move in said longitudinal direction in said fastening arrangement receiving space. This is beneficial for allowing the wall element to be displaced in said longitudinal direction before clamping the wall element, by the clamping element. This is beneficial for allowing to realise a predetermined position, in the longitudinal direction, of the wall relative to the floor.
Preferably, said clamping element receiving space extends in said longitudinal direction of said elongated base for allowing said clamping element to move in said longitudinal direction in said clamping arrangement receiving space. This is beneficial for allowing the clamping element to be displaced in said longitudinal direction before clamping the wall element, by the clamping element. This is beneficial for allowing to realise clamping at a predetermined position, in the longitudinal direction, of the wall relative to the floor.
In an embodiment of the positioning and fastening device according to the first aspect of the present disclosure, said clamping element and/or said fastening arrangement extend, in said longitudinal direction, along a full length of said elongated base.
According to the second aspect, the present disclosure relates to an assembly comprising the positioning and fastening device according to the first aspect of the present disclosure, said assembly further comprising said wall element and a floor, wherein said elongated base is fastened to said floor and said fastening arrangement is fastened to said wall element, wherein said clamping element is maintained in said second position by said wall element.
Embodiments of the assembly according to the second aspect correspond to embodiments of the positioning and fastening device according to the first aspect of the present disclosure. The advantages of the assembly according to the second aspect correspond to the advantages of the positioning and fastening device according to the first aspect of the present disclosure presented previously.
The assembly according to the second aspect at least partly relies on the insight that the gravity force acting on the wall element may be deployed for realising a clamping force thereby avoiding the need for further means for realising said clamping for maintaining the wall element in the predetermined position.
In this regard, it is beneficial if said assembly comprises a plurality of said modular wall elements, wherein said modular wall elements comprise a first interface arrangement at a first side of said modular wall element and a second interface arrangement at a second side of said modular wall element, wherein said first interface arrangement and said second interface arrangement are each provided with at least one of:

a fluid connector arranged for receiving, via said modular wall element, a fluid, wherein said fluid connectors are mutually communicatively coupled for fluid flow;
an electrical connector arranged for receiving, via said modular wall element, an Alternating Current, AC, mains signal, wherein said electrical connectors are mutually communicatively coupled;

The present disclosure relies at least partly on the insight that realisation of known assemblies having walls comprising electrical wiring and/or ducting for gas or water generally requires realising a wall that is free from utilities such as electrical wiring and/or ducting for gas or water and subsequently rework said wall for integrating said utilities in said wall. The required reworking of the wall is a relative cumbersome activity that may add to the building time for building the building. Moreover, the reworking may add additional cost thereby making the building relatively expensive.
Alternatively, a less attractive wall may be realised by simply placing the electrical wiring and/or ducting for gas or water on an outer surface of the wall, thereby leaving the electrical wiring and/or ducting for gas or water in sight of persons present in the building. Though placing the utilities on the outer surface of the wall may be relative time effective as compared to reworking the wall, placing the utilities may add to the building time for building the building.
By providing a modular wall element provided with fluid connectors that are mutually communicatively coupled for fluid flow and/or with electrical connectors that are mutually communicatively coupled a direct integration of the utilities in the wall, without the need for reworking the wall or without the need for placing the utilities on the outer surface of the wall, may be realised thereby allowing to realise a relative attractive wall in a less cumbersome manner.
By providing the modular wall element with the first and second interface arrangement a relative large wall may be realised in a relative practical manner while realising a direct integration of the utilities in the wall. During installation the interface arrangements of neighbouring modular wall elements may be coupled thereby realising that utilities present in the neighbouring modular wall elements are communicatively coupled. This is beneficial for realising that the utilities may extend along the full length of the wall.
Within the context of the present disclosure the electrical connector may in addition, or alternatively, be arranged for receiving a Direct Current (DC).
It is advantageous if each of said wall elements, preferably said modular wall elements, of said plurality of wall elements are provided with a wall lock device receiving space and a wall lock device that is provided in said wall lock device receiving space and arranged for locking said wall element to said fastening arrangement of said positioning and fastening device, wherein said wall element is locked, by said wall lock device, to said fastening arrangement of said positioning and fastening device. Receiving the wall lock device, by the modular wall element, in the wall lock device receiving space is beneficial for allowing said modular wall element, via the wall lock device, to be fixated to a further part of the building. By providing the wall lock device receiving space the wall lock device may be provided, at least partly, in the modular wall element thereby allowing realisation of a visually attractive wall.
In this regard it is beneficial if said wall lock device comprises an angular transmission, said wall lock device further comprising:

a wall lock actuation arrangement provided with in input element of said angular transmission and an actuation element arranged for rotating said wall lock actuation arrangement about a virtual actuation axis for actuating said angular transmission;

Preferably, said angular transmission comprises a worm drive provided with a worm screw and a worm gear, wherein said input element of said angular transmission is formed by said worm screw and said output element of said angular transmission is formed by said worm gear.
In an embodiment said wall lock device comprises a worm drive provided with a worm screw and a worm gear, said wall lock device further comprising:

a wall lock actuation arrangement provided with said worm screw of said worm drive and an actuation element arranged for rotating said wall lock actuation arrangement about a virtual actuation axis for actuating said worm drive;
a wall lock locking arrangement provided with said worm gear of said worm drive and a wall locking element arranged for locking said wall lock device via said wall locking element to said positioning and fastening device, wherein said wall lock locking arrangement is arranged such that said wall lock locking arrangement is allowed to rotate about a virtual locking axis between a first angular position and a second angular position and wherein said wall locking element is moveable along said virtual locking axis, via actuation of said worm drive through said actuation element, when said wall lock locking arrangement is in said first angular position for realising said locking.

According to the third aspect, the present disclosure relates to a building comprising, a floor, a positioning and fastening device according to the first aspect of the present disclosure and a wall comprising wall elements, wherein wall elements, preferably each wall element, of said wall are fastened to said floor by said positioning and fastening device
Embodiments of the building according to the third aspect correspond to embodiments of the positioning and fastening device according to the first aspect of the present disclosure and the assembly according to the second aspect of the present disclosure. The advantages of the building according to the third aspect correspond to the advantages of the positioning and fastening device according to the first aspect of the present disclosure and the assembly according to the second aspect of the present disclosure presented previously.
According to the fourth aspect, the present disclosure relates to a method for realising an assembly according to the second aspect of the present disclosure, said method comprising the steps of:

providing a positioning and fastening device according to the first aspect of the present disclosure, a wall element and a floor;
fastening said elongated base to said floor;
providing said clamping element in said first position and, while said clamping element is in said first position, provide said fastening arrangement in said fastening arrangement receiving space;
providing said fastening arrangement in a predetermined position relative to said floor;
clamping said fastening arrangement between said clamping element and said elongated base, by moving, by said wall element, said clamping element in said second position.

Embodiments of the method according to the fourth aspect correspond to embodiments of the positioning and fastening device according to the first aspect of the present disclosure and the assembly according to the second aspect of the present disclosure. The advantages of the method according to the third aspect correspond to the advantages of the positioning and fastening device according to the first aspect of the present disclosure and the assembly according to the second aspect of the present disclosure presented previously.
Preferably, during said step of clamping, said wall lock device is used for moving said clamping element in said second position thereof. This is beneficial for realising a clamping force using the gravity force acting on the wall element thereby avoiding the need for further means for realising said clamping for maintaining the wall element in the predetermined position.
It is beneficial if, during said step of providing, said fastening arrangement in a predetermined position relative to said floor, said fastening arrangement is moved in said fastening arrangement receiving space relative to said elongated base.

The positioning and fastening device 101 may optionally be provided with interface organs 111 for providing an interface between the modular wall element 1, the elongated base 105 and the clamping elements 109. The interface organs 111 are supported on a virtual flat plane V formed by the clamping elements 109 and the elongated base 105.
The positioning and fastening device 101 further comprises a floor attachment arrangement 102 for attaching a floor 305 to said positioning and fastening device 101.
Wall lock device 201 comprises a housing 203. Housing 203 is provided with a first housing part 205 and a second housing part 207 that are arranged for being connected to each other via fastening elements 209 and thereby form a housing space for housing elements of the wall lock device 201. The second housing part 207 is provided with further fastening elements 211 for allowing the wall lock device 201 to be fastened to an element of the building 401 such as the modular wall element 1 or wall element 303. The modular wall element 1 and the wall element 303 may be provided with a wall lock device receiving space 41 for receiving the wall lock device 201.
Wall lock device 201 is arranged for locking to the positioning and fastening device 101 and thereby allowing an element of the building 401 such as the modular wall element 1 and/or wall element 303 to be locked to the positioning and fastening device 101. The wall lock device 201 comprises a worm drive 213 provided with a worm screw 215 and a worm gear 217. The worm screw 215 is provided as part of a wall lock actuation arrangement 219. The wall lock actuation arrangement 219 further comprises an actuation element 221. The actuation element 221 is arranged for rotating of the wall lock actuation arrangement 219 about a virtual actuation axis A for actuating the worm drive 213. In an alternative embodiment of the wall lock device 201, the worm drive is replaced by a bevel gear.

The wall lock locking arrangement 223 further comprises a wall locking element 225 that is arranged for locking said wall lock device 201, via said wall locking element 225, to said positioning and fastening device 101. The wall lock locking arrangement 223 is arranged such that said wall lock locking arrangement 223 is allowed to rotate about a virtual locking axis B between a first angular position and a second angular position.
The rotation of the wall lock locking arrangement 223 is limited, between said first angular position and said second angular position, by a rotation limiting arrangement 227 of the wall lock device 201. The rotation limiting arrangement 227 comprises a cam 229, a first end stop 231 and a second end stop 233. The cam 229 is attached to said wall lock locking arrangement 223 and blocked for rotation relative to said wall lock locking arrangement 223. The cam 229 is blocked for rotation relative to the wall lock locking arrangement 223 by providing the cam 229 with a surface contour that is arranged to provide a form-locked connection with a locking axis 235 of the wall lock locking arrangement 223. The cam 229 is movable along said surface contour in a direction of said virtual locking axis B. Movement of the cam 229 relative to the housing 203 in the direction of the virtual locking axis B is avoided, or at least greatly limited, by guide elements 204 and a worm gear adaptor 239. The guide elements 204 provide a barrier to movement of the cam 229 at a side of the cam 229 facing the wall locking element 225. The worm gear adaptor 239 provides a barrier to movement of the cam 229 at a side of the cam 229 facing away from the wall locking element 225. The movement of the cam 229 along the surface contour may be realised by screwing a nut 237 and/or the worm gear adaptor 239 onto the locking axis 235. The locking axis 235 is provided with a screw thread (not shown) arranged for cooperation with the nut 237 and/or the worm gear adaptor 239. In a first embodiment of the wall lock device 201 a screwing action of the nut 237 causes a change in distance between the nut 237 and the wall locking element 225. The worm gear adaptor 239 provides an interface between the worm gear 217 and the nut 237 for transferring a rotation of the worm gear 217 to the nut 237. In this embodiment the worm gear adaptor 239 may movable relative to the worm gear 217 and/or the nut 237 in the direction of the virtual locking axis B. Alternatively or in addition, the worm gear adaptor 239 may be provided with screw thread for cooperation with the screw thread provided onto the locking axis 235. In this alternative embodiment, the worm gear adaptor 239 is arranged for driving the cam 229 along said surface contour in the direction of said wall locking element 225 beyond a position that may be achieved with the nut 237. To this end the worm gear adaptor 239 is provided with a protruding wall piece 240 that overcomes a distance between the screw thread provided on the worm gear adaptor 239 and the cam 229.
The first end stop 231 and the second end stop 233 are provided as an integral part of the housing 203. The second housing part 207 of the embodiment according to the figures comprises rib organs forming the first and second end stops 231 and 233. The locking axis 235 comprised by the wall lock locking arrangement 223 is moveable along said virtual locking axis B. Operation of the worm drive 213 through actuation of the actuation element 221 may result in the cam 229 to contact the first end stop 231. Once the cam 229 is in contact with the first end stop 231 a further actuation of the actuation element 221 in a direction of rotation that is identical to the direction of rotation performed for realising that said cam 229 to be in contact with the first end stop 231 will cause the locking axis 235 to move such that the locking element 225 is moved towards the worm screw 215 of the worm drive 213. By movement of the locking element 225 relative to the housing 203 a distance between the locking element 225 and the housing 203 is reduced allowing to clamp a further element of the building 401 between the locking element 225 and the housing 203 for realising locking by the wall lock device 201.
Assembly 301 as part of building 401 comprises the modular wall element 1, the positioning and fastening device 101 and wall lock devices 201. Assembly 301 further comprises wall element 303 and floor 305. Floor 305 comprises a floor element lock device 307. The floor element lock device 307 is received in a through hole provided in the floor 305 and arranged for fixating the floor 305 to the floor attachment arrangement 102 of the positioning and fastening device 101. The wall element 303 is provided with two of the wall lock devices 201. A first wall lock device 201a of the two wall lock devices locks the wall element 303 to the positioning and fastening device 101. The second wall lock device 201b of the two wall lock devices is arranged for locking the wall element 303 to a further wall element (not shown) for forming a wall. The modular wall element 1 is locked to the wall element 303 via fastening means 4 that are provided in said wall attachment arrangements 2.
Method 501 is arranged for realising a wall comprising a plurality of modular wall elements 1. Method 501 comprises a step 503 of providing the modular wall elements 1 and the positioning and fastening device 101. Method 501 further comprises a step 505 of placing the first modular wall element of the modular wall elements on the positioning and fastening device 201 and receiving the positioning and fastening device 101 in the positioning and fastening device receiving recess 39 of the first modular wall element 1. In a yet further step of the method 501 during a step 507 a second modular wall element of the plurality of modular wall elements is placed on the positioning and fastening device 101, wherein the positioning and fastening device 101 is at least partly received in the positioning and fastening device receiving recess 39 of the second modular wall element.
A further step of method 501 is a step 509 of connecting a first interface arrangement of a first modular wall element 1 of the plurality of modular wall elements to a second interface arrangements of a second modular wall element 1 of the plurality of modular wall elements such that the fluid connectors 33 and the electrical connectors 37 of the first modular wall element 1 and the second modular wall element 1 are connected for realising a communicative coupling for fluid flow between the first modular wall element and the second modular wall element and a communicative coupling of the electrical connectors 37 between the first modular wall element and the second modular wall element. During step 507 of connecting, the first modular wall element 1 is moved along the positioning and fastening device 101 relative to the second modular wall element for realising said connection and the wall.
In an alternative embodiment of method 501, method 501 is used with wall elements 303 for locking a plurality of wall elements 303 to the positioning and fastening device 101 instead or in addition to locking of the plurality of modular wall elements 1 to the positioning and fastening device 101. In this alternative embodiment of the method 501, the wall lock device 201 may be provided inside and/or attached to the wall elements 303.
Method 601 is arranged for realising assembly 301. Method 601 comprises a step 603 of providing the positioning and fastening device 101, the modular wall element 1 and the floor 305. During a subsequent step 605, the elongated base 105 of the positioning and fastening device 101 is fastened to the floor 305. Method 601 further comprises a step 607 of providing the clamping element 109 in the first position and, preferably while the clamping element 109 is in the first position, provide the fastening arrangement 103 in the fastening arrangement receiving recess 39 of the modular wall element 1.
