Definitions

  • the present invention relates to a device and method for panelling a structure in connection with construction.
  • the device according to the invention particularly relates to a gypsum plasterboard for panelling a structure in connection with construction.
  • Gypsum plasterboards of this type are commonly used for panelling interior walls and ceilings in buildings, such as houses and industrial buildings.
  • Prior art devices of this type comprise gypsum plasterboards having two opposite and substantially plane surfaces.
  • Such prior art devices for panelling for example, interior walls and ceilings are rectangular and comprise a circumference of four plane edge sides. Further, such devices are arranged to be brought onto and attached to a structure, such as an underlying surface or a framework, by means of conventional fastening means.
  • Such fastening means can, for example, comprise screws, nails or similar.
  • the gypsum plasterboards are attached to a framework of wood or steel, wherein the gypsum plasterboards are fastened to the framework by screws so that one plane surface of the gypsum plasterboards engages the framework and the opposite plane surface forms the interior wall or ceiling,
  • a plurality of adjacent gypsum plasterboards are used, which are arranged so that the edge sides are in contact with each other to obtain an interior wall or a ceiling.
  • the gypsum plasterboards can also be arranged so that two layers of gypsum plasterboard are obtained. Then, the plane surface of the gypsum plasterboard forming the interior wall or ceiling can be painted, provided with wall paper or be subject to any other finishing treatment.
  • the mounted gypsum plasterboards can have a deficient capacity to resist forces in a direction perpendicular to the plane of the gypsum plasterboards.
  • One object of the present invention is to eliminate the above mentioned drawbacks and problems with this type of prior art devices.
  • one object of the invention is to provide a device that results in a more rigid construction in connection with panelling a structure with gypsum plasterboards and which more efficiently can resist forces perpendicular to the plane of the gypsum plasterboards.
  • the device according to the invention further results in an easily mounted gypsum plasterboard, which results in a more cost efficient mounting.
  • Yet another object of the present invention is to provide a device which results in that gypsum plasterboards can be mounted on a structure or a load carrying structure in a lying position while maintaining a rigid construction.
  • the present invention comprises a device for panelling a structure in connection with construction, comprising a gypsum plasterboard having two opposite and substantially plane surfaces and at least a first edge side and a second side edge, wherein the first edge side comprises a projecting portion and the second side edge comprises a recess corresponding to the projecting portion so that the recess and the projecting portion form means for interconnecting adjacent gypsum plasterboards.
  • the gypsum plasterboard can be formed with conventional dimensions, such as thickness, width and length, and is arranged for mounting on a structure or framework of wood, metal, gypsum or similar.
  • the gypsum plasterboard further comprises a third and fourth edge side, which can be formed in a conventional manner or can comprise a projecting portion and a recess, respectively, in similarity with the first and second edge sides.
  • the projecting portion can be arranged in a plurality of different shapes, such as a semi-circle, triangle or rectangle.
  • the projecting portion is arranged to project into the recess and consequently engage an adjacent gypsum plasterboard for interconnection thereof.
  • the recess is arranged correspondingly to receive and partially enclose the projecting portion.
  • the projecting portion and the recess can be arranged along the length of the edge sides, respectively, i.e. from a first end of the edge side to a second end of the edge side or along the entire length of the edge sides, respectively.
  • the projecting portion and the recess are arranged intermittently along the length of the edge sides, respectively, so that the edge sides alternately are arranged with conventional portions and projecting portions and/or corresponding recesses.
  • the projecting portion and the recess can be arranged centrally along the edge sides.
  • the edge sides can comprise plane portions adjacent the projecting portion and the recess so that a first plane portion is arranged on one side of the projecting portion and the recess and a second plane portion is arranged on the opposite side thereof.
  • the edge sides of the gypsum plasterboard can also comprise a chamfered edge.
  • the chamfered edge can be arranged towards the first plane surface of the gypsum plasterboard.
  • the chamfered edge can be arranged between the first plane surface of the gypsum plasterboard and the first plane portion of the edge side. Then, the projecting portion and the recess can be somewhat displaced towards the second plane surface of the gypsum plasterboard to provide space for the chamfered edge.
  • the invention also relates to a method for panelling a structure in connection with construction by means of a device according to the invention, comprising the steps of connecting a first gypsum plasterboard with the structure, bringing the projecting portion or the recess of a second gypsum plasterboard to engage the recess or the projecting portion of the first gypsum plasterboard to prevent displacement pf the gypsum plasterboards in a direction perpendicular to the plane of the gypsum plasterboards and obtain a connection between them, and further connecting the second gypsum plasterboard with the structure.
  • a large surface of the edge sides is provided, which can be coated with glue for further interconnection of adjacent gypsum plasterboards.
  • glue can be applied to a plane surface of the gypsum plasterboard for connection with the structure.
  • a glue which forms a wet suction effect between the gypsum plasterboards and the structure in a first wet condition, is applied to a first plane surface of a gypsum plasterboard. Then, the first plane surface of the gypsum plasterboard is brought into contact with the structure and is detained by means of the wet suction effect of the glue, wherein the gypsum plasterboard is displaceable in a direction along the plane of the gypsum plasterboard to enable correction of its position in the same direction.
  • the position of the gypsum plasterboard can be adjusted in a direction along the plane of the gypsum plasterboard, whereupon the gypsum plasterboard is stationary fixed to the structure by means of the glue, which in a second dry condition forms a fixed connection through increased adhesive and cohesive forces due to solidification.
  • the gypsum plasterboards can be interconnected by means of the glue, by applying the glue on the projecting portion and/or the recess. Alternatively, the glue can be applied on suitable edge sides. Further, gypsum plasterboards can be connected to a conventional structure, such as a framework of wood or metal or an underlayer of gypsum, by means of the glue. The term structure also includes wall frameworks, base structures and similar. The gypsum plasterboards can also be connected with frameworks of expanded metal latches.
  • the glue forms a wet suction effect between the gypsum plasterboard and the structure in a first wet condition and a fixed connection between the gypsum plasterboard and the structure in a second dry condition.
  • the glue shows a relatively high wet suction effect so that a gypsum plasterboard is detained on the structure by suction.
  • the glue is arranged to fasten to the structure and the gypsum plasterboard, wherein a movable connection between the gypsum plasterboard and the structure is provided, which resists forces in a direction perpendicular to the plane of the gypsum plasterboard but enables displacement of the gypsum plasterboard laterally, vertically or in the plane of the gypsum plasterboard. Consequently, the glue connects the gypsum plasterboard with the structure in a wet or non-solid condition and shows low resistance against shearing strain in this condition. This results in that a gypsum plasterboard can be fastened to the structure and then be adjusted for position in a simple manner. When the glue solidifies the gypsum plasterboard is connected with the structure due to the increasing adhesive and, particularly, cohesive properties of the glue.
  • the glue can be water-based and may comprise a polymer in the form of an acrylate copolymer, such as styrene-acrylate copolymer or similar.
  • the glue can further comprise filler, thickening agent, film former, wetting agent and tack agent.
  • the filler comprises dolomite or filler with similar properties.
  • the glue can further comprise a dry content between 70 and 100 percentage by weight, suitably between 80 and 90 percentage by weight and preferably about 86 percentage by weight.
  • the glue can have a relatively thick consistence, which in combination with the dry content, provide a wet suction effect suitable for the application.
  • the glue has a consistence corresponding to 5mm with a needle weight of 20g during 5s with the penetration method.
  • the present invention further comprises a building element comprising at least one construction plate connected to a structure, wherein the construction plate comprises a gypsum plasterboard having two opposite and substantially plane surfaces and at least a first edge side and a second edge side, characterised in that the first edge side comprises a projecting portion for engaging a recess of a gypsum plasterboard adjacent the first edge side, which recess corresponds to the projecting portion, and the second edge side comprises a recess for receiving a projecting portion of a gypsum plasterboard adjacent the second edge side, wherein the recess and the projecting portion form means for interconnecting adjacent gypsum plasterboards.
  • a plane surface of the gypsum plasterboard can be provided with glue to obtain a building element in which gypsum plasterboards are connected with the structure by means of the glue.
  • the glue is applied on the edge sides of the gypsum plasterboards to provide interconnection thereof.
  • the first and/or second edge side can be provided with the glue for further connection between gypsum plasterboards.
  • the recess and/or the projecting portion of the gypsum plasterboards are provided with glue.
  • the third and fourth edge side which may be arranged conventionally or may comprise a projecting portion and a recess, respectively, in similarity with the first and second edge sides, can be provided with glue.
  • Gypsum plasterboards having a recess and projecting portion can be manufactured with or without a carton coating.
  • the recess and the projecting portion can be milled off by means of a suitable milling machine. For example, notches through the carton are cut by means of two saw blades to prevent the material to fluff, wherein a saw notch is formed. Then the recess and the projecting portion are formed by milling by means of wheels provided with milling blades, which mill along the saw notch.
  • gypsum plasterboards having a carton coated recess and a carton coated projecting portion notches can be scribed in suitable positions in the carton, i.e.
  • the carton coated projecting portion is for example formed by folding the carton at the notches and the carton coated recess is for example formed by means of a moulding tool forming the recess and, simultaneously, push carton therein.
  • the back carton is applied and is glued conventionally. Also cutting to suitable length is performed conventionally. For example, a rough cutting is performed on carton coated gypsum paste to obtain pieces with suitable length. Then, these are brought into a furnace, whereupon the length is tuned to provide gypsum plasterboards having suitable length.

  • the gypsum plasterboards can also be fastened to the structure or the latches by means of the glue to connect the gypsum plasterboards with the structure. Then, the structure is suitably provided with glue, wherein the gypsum plasterboards are brought into contact therewith.
  • a first gypsum plasterboard according to the invention is connected with a structure by means of glue.
  • the glue is applied to at least one portion of the structure and/or at least one portion of the first plane surface of the gypsum plasterboard.
  • the glue is applied to the structure, wherein the gypsum plasterboard or the first plane surface of the gypsum plasterboard is brought into contact with the glue on the structure.
  • the glue is arranged to form a wet suction effect between the gypsum plasterboard and the structure in a first wet condition, wherein a gypsum plasterboard is detained by suction and resists forces in a direction perpendicular to the plane of the gypsum plasterboard while allowing displacement of the gypsum plasterboard in the plane of the gypsum plasterboard. Consequently, when required the position of the gypsum plasterboard can be adjusted laterally and vertically due to that the glue shows a low resistance to shearing strain in the wet condition.
  • the properties of the glue can in the wet condition be similar to high adhesion and low cohesion, wherein the cohesion is low in a direction along the plane of the gypsum plasterboard.
  • the cohesion is high in a direction perpendicular to the plane of the gypsum plasterboard.
  • the gypsum plasterboard 10 is fastened to the structure by means of increasing cohesive and adhesive forces of the glue during solidification so that the gypsum plasterboard is fixed to the structure.
  • the gypsum plasterboard is stationary fastened to the structure by means of the glue, which forms a fixed connection through increasing cohesive and adhesive forces due to solidification.
  • a second gypsum plasterboard and additional gypsum plasterboards can then be connected with the structure in a corresponding manner. Edge side of the gypsum plasterboards are then, for example, provided with the glue for interconnection thereof.
  • the gypsum plasterboard When the gypsum plasterboard is arranged in a suitable position it is further fastened by means of conventional fastening means, such as screws. Screws are, for example, arranged in the corners of the gypsum plasterboard to fasten the gypsum plasterboard while the glue solidifies. A second gypsum plasterboard and additional gypsum plasterboards can then be connected with the structure in a corresponding manner. Then, the second plane surface of the gypsum plasterboards can be provided with paint, tapestry, wallpaper or similar.
  • conventional fastening means such as screws. Screws are, for example, arranged in the corners of the gypsum plasterboard to fasten the gypsum plasterboard while the glue solidifies.
  • a second gypsum plasterboard and additional gypsum plasterboards can then be connected with the structure in a corresponding manner. Then, the second plane surface of the gypsum plasterboards can be provided with paint, tapes
  • a suitable number of gypsum plasterboards can be arranged on a structure forming a building element.
  • the building element comprises at least one gypsum plasterboard connected with the structure by means of the glue.
  • the building element also comprises the screws.
  • such a building element also comprises paint, tapestry, wallpaper or similar arranged on the second plane surface of the gypsum plasterboards forming prefabricated building elements for walls, interior walls, roof, ceilings or floors, which demands a low supplementary work effort.
  • the glue shows a relatively high wet suction effect so that a gypsum plasterboard is detained on the structure by suction.
  • the glue is arranged to fasten to the structure and the gypsum plasterboard, wherein a connection between the gypsum plasterboard and the structure is provided, which resists forces in a direction perpendicular to the plane of the gypsum plasterboard but enables displacement of the gypsum plasterboard laterally, vertically or in the plane of the gypsum plasterboard. Consequently, the glue detains the gypsum plasterboard on the structure in a wet or non-solid condition and shows low resistance against shearing strain in this condition.
  • the glue is water-based and comprises a polymer in the form of an acrylate copolymer, such as styrene-acrylate copolymer or similar.
  • the glue further comprises filler, thickening agent, film former, wetting agent and tack agent.
  • the filler comprises dolomite or filler with similar properties.
  • the glue further comprises a dry content between 70 and 100 percent by weight, suitably between 80 and 90 percent by weight and preferably about 86 percent by weight.
  • the glue can have a relatively thick consistence, which in combination with the dry content, provides a wet suction effect suitable for the application.
  • the glue has a consistence corresponding to 5mm with a needle weight of 20g during 5s with the penetration method.
  • the projecting portion and the recess results in a larger contact surface between the first and second edge sides, which is advantageous when interconnecting adjacent gypsum plasterboards by means of the glue. Due to that adjacent gypsum plasterboards are connected in this way, mounting is facilitated. This results in a reduced working effort for holding the gypsum plasterboards in position for further fastening by means of screws, nails, glue or any other suitable fastening means, which results in a more cost efficient mounting. Due to that the gypsum plasterboards are interconnected by means of the projecting portion and the recess less screws, for example, are required to obtain a sufficient connection with the structure.
  • a first gypsum plasterboard is connected to a structure by means of the glue.
  • the gypsum plasterboard is further connected with the structure by means of screws, as described above.
  • a second gypsum plasterboard is brought into contact with the first gypsum plasterboard, wherein the means for locking adjacent gypsum plasterboards of the gypsum plasterboards are brought into contact with each other.
  • the gypsum plasterboards are mounted in the same direction so that the first edge side of each gypsum plasterboard is arranged in one direction and the second edge side is arranged in the opposite direction.
  • the projecting portion of the first gypsum plasterboard is brought into contact with the recess of the second gypsum plasterboard, wherein the gypsum plasterboards are connected by the projecting portion engaging the recess and the glue. Then the second gypsum plasterboard is further connected with the structure by means of screws, as described above.
