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, and wherein the tongue and the groove are designed in that way that, when laying together two essentially substantially uniform boards (19, 20), the other board (20) being turned upside-down in relation to the first one (19) the tongues of the two boards will fit exactly into the grooves of the two boards, whereby the joint between the boards (19, 20), put together, gets such a strength that it could be placed between two adjacent beams in a floor with beams.
  • This invention intends to improve the 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, where a joint with improved strength is provided.
  • a board of the kind mentioned by way of introduction which has the features mentioned in claim 1.
  • FIG. 1 shows a floor with beams, where the particle board according to the invention is used
  • 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 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. Due to that fact 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.
  • 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:
  • 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.
  • To this high strength of the mentioned joint contributes also that fact that the new profile is well counterbalanced.
  • Fig. 3 where it can be seen that the floor profile is "symmetrical" with regard to the line 15, i.e. the volume of the tongue 13 is essentially the same as the volume of the groove 16.
