Definitions

  • the invention relates to a wooden formwork with tongue and groove interlocking profile boards, expansion joints being provided between the abutting surfaces of the profile boards facing each other in the width direction.
  • formwork is known from utility model 19 70 190, the profiled boards of which are bevelled at an outer edge of the groove in a pointed wedge shape, the sharp edge forming the mutual stop during assembly. If the source pressure is excessive, the edge should compress by it bends or breaks off. Apart from the difficulty of producing such a sharp edge, this does not represent a reliable stop when the profile boards are tapped together. Also, bending or breaking off the edge leads to cosmetic defects and accordingly to complaints about the formwork if the rear side is visible.
  • the invention is based on the object of proposing a formwork which can be provided with constant expansion joints without any additional devices or special tools and without impairing the clean appearance on both sides during normal processing.
  • knobs protruding in the width direction are formed on the springs of the profile boards. This can preferably be done in that the end faces of the springs are lightly milled in sections, the nubs then remaining between the milled sections. For example, they can be a few millimeters long or pointed.
  • the spacing of the knobs from one another is preferably chosen to be of the same size and is, for example, approximately between 30 and 60 cm. Since the knobs are formed from the grown wood, they cannot be lost or their function impaired during the further processing of the profiled boards and during transport, in particular due to the influence of wood preservatives or paints.
  • spacers are introduced into the grooves of the profile boards. These can be clamps or nails pressed into the bottom of the groove, which are preferably made of plastic to protect the sawing tools used to shorten the profile boards. But it can also be other spacers, for example spherical or cuboid from any materials, for example made of wood, can be glued into the groove or clamped between the groove side walls. All of the spacers hereby addressed also have the effect of serving as spacers under the low forces when the formwork is tapped together, while being squeezed together or pressed into the wood under the much higher swelling pressure.
  • the attachment of the spacers to the profile boards is best done in connection with the side processing, e.g. B. as an additional device of the throat planer.
  • An application disk can be provided which runs with its peripheral region in the groove.
  • the spacers, optionally coated with glue, can be loaded automatically into the recesses in the edge of the disc and then inserted into the groove at intervals as they continue to rotate.
  • the P rofilbrett according to Figures 1 and 2 has a common cross-section '.
  • a groove 1 is formed on the left side and a tongue 2 is formed on the right side.
  • the tongue 2 engages in the groove of the neighboring profile board, whereby the individual boards are connected to form a coherent formwork.
  • the profile boards are fastened, in particular screwed, on transverse retaining strips, not shown.
  • the width of the profile board during its production is dimensioned such that the tongue would completely fill the groove 1 of the neighboring profile board at the mutual spacing of the profile boards shown in FIG. 1.
  • another end mill 3 is arranged on a clock-controlled swivel arm 4.
  • the milling cutter 3 is temporarily in the position shown, whereby the spring 2 on the end face decreases by the dimension d, which is approximately 2 mm.
  • the arm makes a move to the right and thereby lifts the milling 3rd Immediately afterwards he moves back to the previous one Position back and after a certain time interval the game repeats itself.
  • knobs 6 When the profile boards are plugged together, these knobs 6 abut the bottom of the groove 1, into which the tongue 2 has been inserted. However, if the wood swells under the influence of moisture, the extremely strong swelling forces act at the set pressure points formed by the knobs 6, which leads to the fact that the wood is locally compressed on the knobs or the knobs are pressed into the surrounding wood.
  • the formwork can cope with such local stresses because the profiled boards can expand freely, the springs 2 penetrating further into the grooves 1 while filling in the expansion joints created by the milling.
  • target pressure points are provided in the groove 1.
  • the stops here are not formed by shaping the grown wood, but by U-shaped clips 7 made of plastic, which are pressed into the bottom 8 of the groove 1 with their pointed legs. As shown, the web of the clamp 7 protrudes about two mm above the bottom 8 of the groove.
  • a pressure wheel which is mounted similarly to the milling cutter 3, can be used for the automatic attachment of the clamps 7. Det be attached to the circumferential recesses for receiving the brackets 7 and the stroke determines the distance between the brackets 7.
  • clamps 7 form a stop during assembly and are completely pressed into the wood by the swelling forces.
