Definitions

  • the object of the invention is a building construction such as a wall or ceiling, comprising at least two building boards or sheets forming a joint seam, and an interlocking element for joining together said building boards or sheets.
  • the object of the invention is further a building sheet or board which can be joined to another building sheet or board to form said building construction.
  • Pre-fabricated units of very light partition walls intended mainly for open-plan offices are known. More solid, especially sound-proof separating walls must, however, be built on site from conventional building boards and other building materials needed. The coating of the building boards, such as painting must, therefore, also be done on site. It has not been worthwhile to pre-fabricate ready-coated building boards or building units made of building boards for more solid constructions. One of the reasons for this is that there is no appropriate interlocking system for joining together boards or units, which could be used without damaging the coating of finished sheets or units. Especially with building boards that break easily around the edges, such as gypsum board, it has been impossible to pre-fabricate ready-coated building units, also for the reason that their edges do not withstand transportation or handling on the building site.
  • WO-A-91/10787 discloses an interlocking device for joining together adjacent wall elements.
  • the side edges of the adjacent walls are shaped so that they can be attached to each other by a separate T-shaped device, which has the same length as the wall elements.
  • US-A-5 022 207 describes another interlocking system wherein the side edges of the adjacent building elements are shaped so that they form the interlocking element. A lug on one of the shaped profiles secures the interlocked position.
  • US-A-4 522 007 describes a further system for interlocking building panels together, where the side edges of the adjacent building elements are shaped so that they form the interlocking element. Lips on the shaped profiles secure the interlocked position.
  • the aim of the present invention is to eliminate the said disadvantages and to present an interlocking element and interlocking system by means of which building boards, building sheets and building units can easily be joined together into larger constructions.
  • Building boards and sheets, and building units equipped with the components of the interlocking system relating to the invention can be finished already at the factory.
  • the components of the interlocking system protect the edges of gypsum boards which are particularly prone to breaking during transportation and handling because the said components - which are prefarably of metal - provide the boards with metal edges. From a wall or other construction made of these building units, an unit can, if necessary, easily be removed and replaced again without breaking or damaging the unit.
  • the interlocking system relating to the invention opens up completely new possibilities to equip building units already at the factory to a great extent.
  • This type of wall unit can, for example, be equipped at the factory with conductor rails for electric wiring.
  • the interlocking system relating to the invention also makes it possible to build sound-insulating constructions from building units.
  • Boards or building units equipped with the interlocking arrangement relating to the invention are particularly well suited for use as wall structures but can alsd be used in other structures, such as ceilings.
  • Figure 1 shows the interlocking element when used for joining together two adjacent boards L1 and L2.
  • the interlocking element comprises two interlocking components: component A which is fastened to board L1, and component B which is fastened to board L2.
  • the interlocking element is essentially of the same length as boards L1 and L2, in other words, where a wall construction is concerned, the interlocking element extends from the floor to the ceiling, as do the boards.
  • the cross-sectional profile of component A consists of a first part (a), extending from the plane of the outer surface of the construction over a certain distance into the construction and forms an almost right-angled construction with the outer surface, and of a second part (b) which continues from the first part (a) and forms an essentially right angle with part (a) and is oriented towards the centre of board L1, and of a third part (c) which continues from the second part (b), bending approximately 180 degrees and running in the opposite direction with respect to part (b), towards the joint seam (s) between boards L1 and L2, and of a fourth part (d) which continues from the third part (c) in the shape of a Z-profile, and remains on the other side of the joint seam (s).
  • Component B which is fastened to the other board, L2, also has essentially the same length as L1 and L2.
  • Component B comprises a part (m), the cross section of which, as shown in the plane of figure 1, is no longer than the cross section of part (a), in order for the outer surface formed by the boards L1 and L2 to be even.
  • Part (m) extends from the plane of the outer surface of the construction over a certain distance into the construction, and forms an essentially right angle with the outer surface of the construction.
  • Components A and B may be fastened in different ways to the boards L1 and L2, respectively.
  • component A has a part (e) which is connected through part (f) to part (a).
  • Part (e) is parallel to the side surface of board L1 and fastened to the board, for example, by means of screws 10 over the whole length of the board, on the surface remaining inside the construction.
  • Part (f) located between parts (a) and (e) of component A, is an oblique part joining parts (a) and (e).
  • Component B comprises part (n) which is connected to part (m), through part (p).
  • Part (n) is fastened with screws 11, over the whole length of the board, against the inner surface of the board.
  • the point of the clamping device can be made to press against the part assembly (bc) of component A, in which case part (m) of component B fastened to board L2 - the said part being pushed between parts (a) and (d) of component A - is clamped in the joint seam (s), as the lower arc of part (d) is pressed towards parts (a) and (m).
  • the clamping device which is preferably a screw, will then be covered by the skirting, or correspondingly by the cornice moulding or ceiling.
  • the space 12 between the edge of board L1 and part (f) of component A, as well as the space 13 between the edge of board L2 and part (p) of component B are filled with jointing compound, preferably elastic cement which is smoothed to the level of the outer surface of the building board.
  • jointing compound preferably elastic cement which is smoothed to the level of the outer surface of the building board.
  • An interlocking element can be mounted on the side edges of the building boards, as shown in figure 1, so that component A is fitted on the first side edge and component B on the second side edge of the board, in which case this single board type suffices to assemble the construction.
  • two types of boards can be made, so that a component A is fitted on both side edges of the first board type, and a component B is fitted on both side edges of the second board type.
  • the desired construction can be assembled by using the first and second board types alternately.
  • Figure 2 shows the interlocking element when used to join together two adjacent building sheets, L1 and L2.
  • the side edge of the sheet L1 forms a seamless connection with part (a) of component A
  • the side edge of sheet L2 forms a seamless connection with part (m) of component B.
  • This solution comprises a building sheet which is pre-equipped with interlocking components and from which different constructions can be made.
  • two types of sheets can also be made so that parts (a) - (d) of component A are formed on both side edges of the first sheet type, and part (m) of component B is formed on both side edges of the second sheet type.
  • the desired construction can be assembled by using the first and second sheet types alternately.
  • Reference number 14 shows a sleeve made in the sheet into which the screw acting as the clamping device can be fitted. Alternatively, for example a plate screw can be used.
  • a hook can be provided on one component and a groove corresponding to the form of the hook on the other component in the vicinity of the point of contact between the components.
  • Figure 3 shows a detail of an interlocking element provided with a hook 30.
  • Figure 4 shows building units R1 and R1, made of building units L1 - L4 and equipped with the interlocking system relating to the invention, joined together adjacent to each other into a larger construction, for example a wall.
  • Figure 5 shows the construction of figure 4 with one joint of the building unit R2 opened.
  • the first building unit R1 comprises two parallel building boards, L1 and L3, at a certain distance from each other and the adjacent building unit R2 comprises two building boards L2 and L4.
  • component A of the interlocking element described above has been fastened to building boards L1 and L4
  • component B of the interlocking element described above has been fastened to building boards L2 and L3.
  • Component A is fitted to L4 in the same way as to L1, and component B is fitted to L3 in the same way as to L2, as seen from both sides of the construction.
  • part (e) of component A mounted on board L1 is joined to part (n) of component B mounted on L3 by means of an intermediate part (t).
  • part (e) of component A mounted on board L4 is joined to part (n) of component B mounted on board L2.
  • the intermediate part (t) forms a right angle with parts (e) and (n)
  • the interlocking system also provides the best support for the building unit.
  • Figure 4 shows that building units R1, R2 and R3 are identical. In assembling the construction, they are turned alternately. In the solution described component A, component B and the intermediate part (t) connecting them together form an integrated interlocking component assembly.
  • Figure 5 shows that by opening the clamping devices K of the interlocking system which keeps building unit R2 in place, unit R2 can be removed from the middle of the construction.
  • the other building units can be removed in a similar way by removing the units by turns in opposite directions.
  • building unit R2 is removed to the right.
  • Building units R1 and R3, on the other hand, are removed to the left.
  • the distance (v) - in the interlocking system - of the line passing through the joint seam (s) of L1 and L2 from the line passing through the joint seam (s') of L3 and L4 must be at least double with respect to the space required by the Z-profiled part (d) of component A in the transverse direction of the building unit. This ensures that the Z-profiled parts (d) of the different building units in the interlocking system are able to pass each other when one building unit is being removed.
  • Figure 6 shows construction units R1 and R2, made in the same manner from building sheets L1 - L4 and equipped with the interlocking system, joined together adjacent to each other into a larger construction.
  • Reference number 14 refers to a sleeve provided for the clamping device.
  • Figure 7 shows the construction of figure 6 with one joint of building unit R2 opened. Insulating material is normally placed between the metal sheets of the building units so that the sheets are fixed to the insulating material, for example, by glueing.
  • a very soundproof construction can be achieved thanks to there being no metal parts relating to the interlocking system, joining outer surfaces, between the outer surface metal sheets of the construction.
  • a sound bridge formed by building units made of building boards can also be cut by cutting the intermediate part (t) and by joining the cut parts by means of a separate component.
  • the interlocking component assembly shown in figure 8 can be modified, for example, as shown in figures 9 and 10.
  • Figure 9 a piece has been cut off from the intermediate part (t) and replaced by a plastic profile 15.
  • Figure 10 shows an interlocking component assembly in which the intermediate part (t) has been replaced by a two-part intermediate part (t'), the first part (t1) of which continues from part (e) but remains detached from part (n), and the second part (t2) of which continues from part (n) but remains detached from part (e).
  • a certain distance is left between parts (t1) and (t2), and between them is fitted rubber insulation material or the like 16, where parts (t1) and (t2) are joined together.
  • Figure 12 shows the starting point of the installation of a building unit from a solid structure to which the starting component 17 has been fixed.
  • Figure 13 shows the mounting of building units to form a corner.
  • the parts (t) belonging to the interlocking systems are joined together by means of support elements 31 before the installation of the building units.
  • Electric wires can be installed in the building units relating to the invention if part (t) of the interlocking component assembly is provided with holes in the longitudinal direction of the interlocking system, through which holes the wires can be passed from one building unit to another. Conductor rails for electric wires can also be installed in these building units.
  • Figures 14 - 16 show a vertical section of a wall unit and display three alternatives for fastening the building unit to the floor, ceiling, or both.
  • U-shaped profile rails 18 and 19 fastened to both the floor and ceiling in the longitudinal direction of the wall.
  • the building unit is fastened to both the floor rail 18 and the ceiling rail 19 by means of profile components 20 and 21 respectively, so that the unit shown in the figure is released to the right when the screw joints are opened.
  • the units must be mounted to open alternately to the right and to the left.
  • the fastening points of the units in the floor and ceiling rails remain under the skirting and the cornice, respectively.
  • Figure 15 shows an embodiment in which the unit is fastened with screws only to the ceiling rail 19.
  • the joint remains above the ceiling.
  • a profile 22 corresponding to the floor rail 18 keeps the unit in place.
  • the unit can be removed to the right by lifting it upwards after the screw joint in the ceiling has been opened. In this solution there is no need to use skirting.
  • Figure 16 shows a solution in which the unit is fastened only to the floor rail.
  • a profile 23 corresponding to the ceiling rail 19 keeps the unit in place.
  • the unit is removed to the right by removing the skirting, opening the screw joint and lowering the unit.
