Definitions

  • This invention relates to a board, which is made of a material based on wood, preferably particle board, which is suitable to use when laying down floor boards, the board having an essentially rectangular shape with two long sides and two short sides, and at least the one but preferably both short sides having a profile provided with tongues and grooves, which, when laying two boards together, makes possible to form an essentially smooth transition part between the boards.
  • This invention intends to remove the problems with known technique and to provide a board based on wood, preferably a particle board, which makes possible also to place the joint between two boards, put together, between two beams for a floor. This has been achieved by a board of the kind mentioned by way of introduction, which has the features mentioned in the claims.
  • FIG. 1 shows a floor with beams
  • Fig. 2 shows a joint between two particle boards, put together, according to the invention
  • Fig. 3 shows the same picture as in Fig. 1 but with that difference that the particle boards have been drawn out a small distance from each other.
  • Fig. 1 is shown a plurality of rectangular particle boards 1 according to the invention, laid down on a great number of beams 2 for creating a floor with beams.
  • the short sides 3 of the particle boards are provided with the new profile, which makes possible for the joint 4 between two boards 5, 6, put together, to be positioned between two adjacent beams 7, 8.
  • the mounting of the particle boards can be made continuously, which means that, when there is a rest part of a board when finishing a row, it is possible to start the next row with that rest part.
  • This fact leads to a very effective laying down of particle boards with a minimum of material wastage.
  • the long sides of the particle boards are provided with the new profile, adjacent boards interfering with each other. Also that fact contributes to strengthen the joint between the short sides of the boards.
  • the new profile of the short- and long sides of the particle boards leads to an improved function of the joint between two particle boards, put together, and this fact has also that advantage that the number of screws for fastening the particle boards on the beams can be reduced in relation to known technique.
  • Fig. 2, 3 the special profile of the sides of the particle boards 9, 10 for making the strong joint possible is shown more closely.
  • the profile has the following design, seen from the top surface 11 of the particle board in relation to which the tongue has a position above the groove:
  • An obliquely backwards-directed, straight portion 12 which forms an angle of 20- 30° with the vertical line, and which passes over to an obliquely downwards- and forwards- directed, rounded portion 13, which functions as a tongue, and which after the rounding extends essentially straightly backwards approximately at the middle of the depth, i.e. the thickness, of the particle board;
  • the mentioned extension 14 backwards has such a length that it reaches beyond a prolongation line 15 through the portion 12 towards the underside of the particle board and passes over to a backwards directed, rounded portion 16, which functions as a groove, and which has an obliquely downwards- and forwards-directed, straight portion 17, which passes over to an obliquely backwards-directed, straight portion 18, which extends to the underside of the board, and which has such a position that it essentially coincides with the mentioned prolongation line 15 through the portion 12.
  • the profile is designed in that way that the two particle boards 19, 20, which shall be put together, are essentially uniform but are reversed when being put together so that the top surface of the one particle board 19 is directed upwards, whereas the top surface of the other board 20 is directed downwards.
  • the advantage with this arrangement is that only one tool needs to be used, and that, principally, it would be possible to use optional side, directed upwards, when the floor is mounted.
  • the obliquely bevelled parts 12, 18 of the profile portion of the one particle board, when co-operating with corresponding obliquely bevelled parts as of the profile portion of the other particle board 20, has the effect that the forces arising when loading the joint are distributed out to all parts of the joint with an increased strength as a result.
