Definitions

  • the present invention relates to a joint device comprising two sheet-like building elements made for insulating purposes, wherein element portions of both elements extending along the joint border are designed to be brought into engagement with each other and to create a connection between said two elements at the joint by means of a male member comprising a rib extending along the longitudinal direction of the joint and a female member comprising a groove extending along the longitudinal direction of the joint, the convergence of the male member substantially corresponding to the divergence of the female member, wherein the male member is adapted to be freely introducable into the female member until it reaches an introduced position in which substantially the entire surfaces of the lateral wall portions thereof introduced into the female member bear against wall portions of the female member, the dimensions of the male and female members being so chosen with respect to each other that the end surfaces of the rib are located at a certain distance from the bottom of the groove in said introduced position.
  • Such building elements may be used for insulating a building or parts thereof against for instance moisture or radon and so as to reduce the heat exchange between the interior of the building and the surroundings.
  • the present invention generally relates to all conceivable uses of building elements for insulating purposes and in particular those for protecting the foundation of a building against moisture and radon gas from the surrounding ground, for which reason the latter case will be discussed hereinafter in exemplifying but not limiting way.
  • SE-B-0 433 372 illustrates a joint device according to the pre-characterising part of claim 1.
  • this joint device comprises cooperating male and female members, a deficiency with this known joint device is that it is difficult to achieve excellent tightness. This is also due for the joint device disclosed in FR-A-2 345 560.
  • the object of the present invention is to provide a device of the type defined in the introduction, which to a great extent reduces the disadvantages mentioned above and the inconveniences appearing at the level of the joints between building elements of the type in question.
  • This object is according to the invention obtained by a device according the appended claim 1. Thanks to the construction of the element portions of both elements a tight connection between the two adjacent building elements may be achieved at the joint, so that this joint does not constitute any place in which moisture, radon gas or the like may come through the insulation in an easier way than by choosing a way through the very elements.
  • the device according to the invention of course also results in advantages in heat insulation, since it is precluded that an increased flow of heat away takes place at the joint, and a heat insulation having such joints may be especially suitable in an internal supplementary insulating of a house built by blue light-concrete, since this material emits unacceptable amounts of radon gas.
  • At least the surfaces of both elements adapted to form the joint therebetween as well as the sheet plane surfaces located on one side of the elements are according to a preferred embodiment of the invention covered by aluminium foil for reflecting especially radon gas.
  • a joint having an even better possibility to keep the harmful radon gas outside the building is obtained in this way.
  • the building element having a sheet-like body is provided with one or more air channels extending therein between the sheet planes and therealong and means are provided for connecting the air channels to means for generating a negative air pressure therein so as to conduct substances, such as radon gas, entering into the element away therethrough and prevent them from passing through the element.
  • substances such as radon gas
  • the building element having a body of insulating material is provided with small aluminium foil pieces distributed therein. It has turned out that such a building element is very efficient in reflecting radon gas. This ability is not reduced with increasing age of the building element and such a building element may be easily handled without any risk of appearance of damages deteriorating this ability, since the aluminium foil pieces of crucial importance for this ability are embedded in the body of insulating material.
  • sheet-like building elements 1 for insulating purposes and having a device in a joint according to the present invention are shown in Fig 1. It appears that the definition sheet-like is to be interpreted in its broadest meaning, i.e. it does only state that it is a question of an element having two opposite surfaces being substantially parallel to each other, so called sheet plane surfaces.
  • the elements consist preferably of moulded foamed plastic, which has a very low density and a good heat insulating capacity.
  • the building elements are made in one piece and have a rebat-like configuration 2 along the borders intended to be jointly connected to other similar building elements, said configuration having a rib 4 extending along said border and having its free upper end surfaces 3 directed substantially perpendicularly to the sheet planes and a groove 5 extending parallelly thereto and delimited by the rib on one side.
  • lateral walls 6 of the rib 4 converge in the direction towards the free end surfaces 3 thereof, and the lateral walls 7 of the groove 5 diverge from the bottom 8 of the groove by a degree of divergence substantially corresponding to the degree of convergence of the rib 4.
  • the width of the bottom of the groove 5, the thickness of the rib as well as the height of the rib as seen from the bottom of the groove are so dimensioned, that a rib and a groove identically dimensioned of another building element may be brought into engagement therewith while introducing the respective rib into the respective groove until reaching a position in which substantially the entire surfaces of the lateral wall portions of the ribs introduced into the grooves bear against lateral wall portions of the respective groove.
  • the height of these dimensions are so chosen that the end surfaces 3 of the rib 4 are located at a certain distance from the bottom of the groove 5 in said position. Since the building elements are made of foamed plastic, which may be slightly deformed, the respective rib may after reaching said position be pressed in a little bit further into the respective groove while deforming the ribs and adjacent element portions, so that a tightening wedge action is obtained in said joint by the fact that it stores potential energy pressing the surfaces of the ribs and the grooves bearing against each other tightly against each other.
  • the sheet plane surfaces on either side of the joint are intended to be located in substantially the same plane after this further pressing inwardly.
  • the joining of the two elements 1,1' takes place by moving the rebat-like configurations 2 thereof into engagement with each other by a relative movement thereof substantially perpendicularly to their sheet planes from the position according to Fig 2 to that according to Fig 3.
  • the two elements 1, 1' shown in Fig 2 and 3 are covered by aluminium foil 9 on the sheet plane surfaces located on one side, said foil continuing over the rib and groove in question to the opposite sheet plane surfaces. Since the aluminium foil is comparatively sensitive and may easily be torn apart, it is preferably covered by a diffusion tight plastic paste so as to obtain a higher mechanical strength.
  • aluminium foil made in the claims is intended to comprise the case that this aluminium foil has a coating, so that the aluminium foil in the practice does not constitute the very surface layer of said surfaces.
  • the two insulating elements in the region of the joint therebetween function as if they were one single continuous insulating element having one side covered by aluminium foil, while there is also aluminium foil absorbing and reflecting moisture, radon gas and the like which with a low probability will enter into said joint.
  • Fig 1 It is shown in Fig 1 how the rebat-like configuration 2 is arranged on some of the sides of the insulating elements, which however only is made for the sake of simplicity, and it would in the practice be most advantageous to arrange the rebat-like configuration around the entire building elements, and it would then be possible to cut off that building element which will be located outermost in carrying out the insulating.
  • the rebat configuration on the opposite sides of one and the same building element are then preferably directed with the ribs and the groove bottoms in the opposite directions with respect to each other, so that the insulation may be assembled by applying an element for instance on a wall surface, introducing a rib of an adjacent element into a groove of the first element, than introducing a rib of a third element into a groove of the second element and so on by relative movements of the elements with respect to each other substantially in the direction perpendicular to said wall. It is shown in Fig 1 how two building elements 1,1' designed for a joint interconnection have a rib 4" and a groove 5" each also along an end border 31 extending substantially perpendicularly to the joint border.
  • a material saving 32 substantially corresponding to the total width of the rib and the groove in the two dimensions of the sheet planes is carried out in the region in which the joint border and the end border meet in the one element 1, while the rib 4" and the groove 5" of the end border of the other element 1' continue to the joint border. It is in this way achieved that a relative displacement of the two elements 1, 1' along the joint border in the form of a displacement of said one element 1 towards said end border of the other element 1' may only take place until the joint rib 4 of the element 1 comes to bear by means the front surface 33 thereof against the end rib 4" of the other element 1'. This feature facilitates a process for assembling the elements.
  • Typical dimensions of standardized such elements may be: width 600 mm, length 1200 mm and thickness 50 mm.
  • Building elements 26 are schematically illustrated in Fig 4 and 5, which in the case shown have a device in joints of the kind shown in Fig 1-3 and they are for the rest provided with one or more air channels 27 extending between the sheet planes and therealong, said channels being created by laying perforated plastic tubes 28 in the elements 26 when moulding them. It is possible to provide the elements with an amount of air channels in this way which preferably are interconnected on any place, for example by transversal channels extending between channels extending parallelly to each other. The air channels are so arranged that they in jointly interconnecting two building elements 26 will come into mutual alignment for communication therebetween.
  • These air channels are intended to be connected to means indicated in Fig 5 by a fan symbol 29 for generating a negative air pressure in the channels, so that substances, such as moisture and radon gas, entering thereinto will be sucked away from the insulation through the air channels and preferably be emitted to the ambient atmosphere.
  • the negative air pressure may be created by fan means, but it is also possible that it is provided solely by connecting the air channels to the draught air channels of the building.
  • a coating of the building elements with aluminium foil 9 may also be carried out here so as to make these even more unwilling to let radon gas through, and it is also possible to improve this feature further by providing also these elements with aluminium foil pieces embedded in the insulating bodies in the way described above.
  • the building element with more than one rib and groove at one and the same border, so that for instance a series of thin ribs and narrow grooves being substantially mutually parallel could be arranged along a border for engaging into corresponding means of an adjacent element.
