Definitions

  • the subject of the present invention is a device for assembling pieces of construction wood, in particular frames, and a method for producing it.
  • This device makes it possible in particular to bring together and maintain two or more pieces of wood in predetermined relative angular positions and to obtain an integral assembly having great resistance to the forces exerted on these pieces. It allows in particular the realization of triangulated structures such as for example a farm.
  • the assembly devices currently available do not prevent splitting of the pieces of wood, especially at their connection because of the horizontal and vertical shearing forces exerted on these pieces at this level.
  • each assembly node is held in place by a bolt, which is made essential by the very design of these assembly elements.
  • This design leads to a significant reduction in resistance to the forces exerted on the parts to be assembled.
  • the use of a bolt is subject to a removal of matter that we are obliged to compensate for, by oversizing the pieces of wood to be assembled.
  • the object of the present invention is to solve the technical problem consisting in providing a device for assembling pieces of timber, of a new design, which is simple, inexpensive and which is easy to implement, and which allows an integral assembly of very high resistance, without requiring an oversizing of the parts to be assembled.
  • rings means any tubular element with a circular or polygonal cross section, in particular square or rectangular.
  • each plate comprises, around each ring several holes intended to receive spikes allowing the fixing of said plate to at least one of the parts to be assembled.
  • the present invention also relates to solve the technical problem consisting in providing a method for producing an assembly device making it possible to achieve this objective.
  • the extreme edges of the aforementioned central and external rings are bevelled, to allow the aforementioned crimping operation.
  • a perfectly homogeneous assembly device which offers great resistance to the forces exerted on the parts to be assembled, these forces being distributed regularly over each of the rings, and cannot therefore be concentrated on a particular ring.
  • This device does not require, unlike assembly devices known so far, a number of bolts identical to the number of rings to fully achieve the objective set.
  • the method according to the invention applies regardless of the shape (in cross section) of the ring.
  • FIG. 1 therefore shows an assembly device in accordance with the present invention intended to connect two pieces 1, 2, of construction wood, which, in the example shown, must be maintained by forming a substantially right angle between them. . It is clear that this device makes it possible to block two pieces of wood in any relative angular position, such as for example the post and the crossbowman of a glued wooden portal truss. These parts can work either under tension or under compression.
  • the assembly device comprises a substantially flat plate 3, intended to be placed between the parts 1 and 2.
  • This plate 3 comprises a set of cylindrical rings 4 of circular cross section extending from both sides 'other of the plate plane (see Figure 2).
  • the number of rings 4 and their distribution on the plate 3 can be easily determined by a person skilled in the art, in order to avoid horizontal and vertical shearing of the parts 1 and 2, at the level of the plate. For example, we will try to make a "labyrinth" to avoid splitting the wood in the direction of the fibers, by arranging the zigzag rings.
  • the parts of the rings 4 extending on either side of the plane of the plate are inserted in the assembly position (FIG. 3) in recesses 5 of conjugate shape provided on the faces 6, 7, facing parts 1 and 2 to be assembled, these faces 6, 7, coming to bear on the faces of the plate in the assembly position.
  • This assembly device also includes a set of bolts 8, the number of which is less than the number of rings 4 present on the plate, as shown in FIG. 1.
  • the bolts 8 pass through the parts 1 and 2 to be assembled and the plate 3, preferably in holes 9 concentric with some of the rings present on the plate.
  • the plate 3 has around each ring 4 several holes 10 intended to receive ringed points 11 ( Figures 2 and 3). These points make it possible to make the plate 3 integral with the pieces of wood and prevent the initiation of spillage of each ring 4 in its housing provided in the pieces of wood to be assembled.
  • the plate 3 and the rings 4 will preferably be made of metal, for example stainless steel, but may also be made of a rigid composite material, for example by molding.
  • this assembly device has been produced using a stainless steel plate of approximately 1 mm thick, with a resistance of 80 kg / mm2.
  • This process consists in making, by drilling, a set of circular holes in the plate 3.
  • a central cylindrical ring 12 is placed inside each hole, the diameter of which is equal to the diameter of the hole, and which extends on either side of the plane of the plate 3. Then, from on either side of the plate 3 a cylindrical outer ring 13, the height of which is substantially equal to the axial dimension of the part of the central ring 12 projecting from the plate 3, and the internal diameter of which is slightly less than the diameter outside of the central ring, for example 0.3 mm.
  • the end edges 15 and 16 of the central ring 12, and the edge 17, the furthest from the plate 3, the outer rings 13 are bevelled, the edges 15 and 16 of the central ring 12 extending beyond the edges 17 of the internal rings 13.
  • This configuration allows the crimping of the rings 12 and 13 with material delivery as shown in FIG. 5 which represents the ring 4 after crimping. This ensures perfect attachment of each ring on the plate with self-centering of the inner ring 12 by the outer rings 13, during hooping and crimping.
  • the plate being of a reduced thickness, the aesthetics of the assembly is maintained.
