Definitions

  • Timber-framed buildings are constructed by assembling several wooden panels made of cross-laminated timbers. These timbers form the wall structure. Functional panels, such as thermal insulation, sound insulation, fire resistance, or panels serving any other purpose, are inserted between the timbers.
  • the role of the wall structure is to provide sufficient rigidity to this stack of slats to prevent buckling.
  • the wall can withstand the forces exerted upon it, particularly by strong winds, earthquakes, or any other action defined by regulations. These forces are horizontal and induce shear stress within the walls. In a structure composed of several walls, it is necessary to ensure the transfer of these horizontal forces to the building's foundations.
  • FIG.1 represents two wall structures 10.
  • Each structure 10 is composed of overlapping and interlocking wooden slats 14, 16. They form a trapezoidal grid, with spaces into which functional plates (not shown) can be inserted during assembly.
  • the documents FR2562582A1 And FR3080871A1 each disclose respectively a structure comprising an assembly of blades having all the characteristics of the preamble of claim 1.
  • One of the structures 10 (located at the bottom of the [ Fig.1 ]) is used as a floor, therefore placed horizontally on the ground. This first structure 10 will therefore be called from now on "floor structure 10.
  • the other structure 10 (located at the top of the [ Fig.1 ]), of the same type, is attached to it perpendicularly on one side to form a wall.
  • This second structure 10 will therefore be referred to hereafter as "wall structure 10".
  • the other three walls are not shown for clarity.
  • the wall structure 10 consists of overlapping layers of horizontally arranged boards called “cross members 14" and vertically arranged boards called “stile members 16". At each intersection between a stile member 16 and a cross member 14, joining means are arranged between the stile member 16 and the cross member 14. These intersections will subsequently be referred to as "joints”.
  • the floor structure 10 has an identical structure to that of the wall structure 10, but it is lying in a horizontal plane.
  • the floor structure 10 is subjected to shear forces that can be continuously distributed along its edges. These forces are represented by the arrows F1. Part of the shear force is directed along the direction of the vertical members 16, while the other part is directed along the horizontal members 14.
  • the first blade is striated with parallel grooves consisting of alternating straight grooves cut into said contact area.
  • the second blade has, at the point of contact with the first blade, raised bumps extending from a base face. These bumps are created by first grooving in a direction generally parallel to the blade, then grooving in a transverse direction (which is not necessarily exactly orthogonal to the primary parallel grooving direction).
  • the protruding pins engage in the grooves. Any relative movement of one blade with respect to the other in a direction perpendicular to the grooves is blocked by the pins, which come to rest against the edges of the grooves. However, the pins can still slide along the grooves.
  • Each contact zone 18 is divided into two parts, namely an upper part 20 and a lower part 22.
  • the front face 14a of a cross member 14 is grooved along its entire length in the direction of the wood grain along the X-axis.
  • the lower part 22 is textured, while the upper part 20 remains simply grooved along the X-axis.
  • the front face 16a of a slat 16 of the upright is grooved along its entire length in the direction of the wood grain along the Y axis.
  • the upper part 20 is studded, while the lower part 22 remains simply grooved along the Y axis.
  • the rear face 16b of a slat 16 of the upright is grooved along its entire length in the direction of the wood grain along the Y axis.
  • the upright blades 16 and the cross blades 14 are superimposed and fitted into each other at their contact areas 18, then held in position by screwing, with one or more screws 24.
  • This assembly method is particularly advantageous because it allows for the automated production of the structures, for example, by using a robotic arm in the workshop.
  • the blades, whose contact areas have been pre-machined to form the textured and grooved sections, are thus automatically and quickly placed one on top of the other. Finally, the tightening screws complete the assembly of these structures.
  • each blade must be grooved and pitted on both sides. This requires rotating the blade several times (for example, four times) on the grooving machine, which complicates the grooving process and increases its machining time.
  • the creation of the studs and grooves is achieved by removing material from each slat. Consequently, a significant proportion of the wood slat's thickness, for example, around 20%, is no longer functional. This results in a waste of wood.
  • the invention thus offers a highly advantageous way to create patterns that allow for effective and secure locking of the boards against each other in all directions, without being limited by the machining techniques used for the wood. Furthermore, the invention eliminates the need to machine the wood and thereby avoid losing a significant portion of its thickness.
  • the boards are locked together by their interlocking upper surfaces, which fit together through the interlocking of the patterns.
  • the interlocking patterns are in relief.
  • the interlocking patterns are repeated regularly and identically across the entire upper surface.
  • the interlocking pattern has an alternating pattern of bumps, extending above a median plane, and recesses, extending below a median plane, each recess having a shape complementary to each bump of the other locking plate to allow one locking plate to be fitted into the other. This feature allows each bump to contribute to locking the blade in all directions of the transverse longitudinal plane.
  • the recesses and raised areas of an interlocking pattern are arranged adjacent to one another, with two raised areas joined by a collar arranged at the level of the median plane. This arrangement allows for a high density of recesses and raised areas, thus strengthening the locking of the two blades.
  • the interlocking pattern is formed by a regular tiling of identical hollows and identical bumps, each hollow having a shape complementary to each bump. This feature makes it possible to obtain a dense and regular arrangement of hollows and bumps.
  • each hollow and each bump in view of sectioning along the median plane, has the shape of a square, with the bumps and hollows arranged in a square pattern.
  • This feature represents one of two existing configurations for obtaining a plate with a regular pattern of hollows and bumps that can be fitted together with another identical locking plate.
  • each hollow and each raised area in cross-section along the median plane, has the shape of an equilateral triangle, the raised areas and hollows being arranged in a triangular pattern.
  • This feature represents the second of two existing configurations for obtaining a plate with a regular pattern of hollows and raised areas that can be fitted together with another identical locking plate.
  • the hollows are formed by parallel, non-straight grooves, and the raised areas are formed by raised ridges completely separated by the hollows.
  • the locking plates are fixed to their respective blades by gluing. This feature allows the locking plate to be fixed to any type of wood.
  • all the bumps of the interlocking pattern have the same height from the median plane and all the recesses of the interlocking pattern have the same depth from the median plane, said height and said depth both being greater than or equal to 3 mm.
  • the longitudinal direction corresponds to the length of a slat
  • the transverse direction to the width of a slat
  • the vertical direction to the thickness of the slat.
  • the vertical direction is used as a geometric reference point unrelated to the direction of gravity.
  • a wooden blade 14 forms a cross blade 14.
  • the cross blade 14 is bounded along its thickness by two transverse longitudinal faces, which will hereafter be called the front face 14a and the rear face 14b.
  • the cross blade 14 extends along a principal longitudinal axis "Y".
  • the cross blade 14 is bounded transversely by longitudinal edges 26 and longitudinally by transverse edges 28.
  • the edges 26 and 28 have a thickness much less than the width of each face.
  • a structure 10 is made by assembling several blades 14, 16 for the fabrication of a wall or a truss beam.
  • the structure 10 is made, as in the prior art, by superimposing interlocking wooden blades 14, 16, forming upright blades 16 and crossbeam blades 14.
  • the assembly includes at least one upright blade 16, oriented along the principal "X" axis and having the front face 16a.
  • the assembly also includes at least one crossbeam blade 14, oriented along the principal "Y" axis and having the rear face 14b.
  • the main "X" axis of the upright 16 blade forms an angle " ⁇ " with the main "Y” axis of the cross member blade.
  • This is an angle “ ⁇ ” understood generally between -180° and 180°, preferably excluding the value 0°.
  • the angle " ⁇ ” is preferably between +/-30° and +/-120° in rotation in either direction.
  • the angle " ⁇ ” has a value approximately equal to +/-30°, +/-45°, +/-90°, +/-125° or +/-150°. In the example shown in the [ Fig. 7 ], the angle " ⁇ " is 90°.
  • a contact zone 18 of the front face 16a of the upright blade 16 is in planar support against a complementary contact zone 18 of the rear face 14b of the cross blade 14.
  • Each locking plate 30 extends in a transverse longitudinal plane of the associated wooden blade 14, 16.
  • the locking plate 30 has, in the thickness direction, a base 32, shown at the bottom of the [ Fig. 9 ], and an upper interlocking face 34, shown at the top in the [ Fig. 9 ].
  • the underside of the sole has cleats designed to be driven into the contact area of the associated wooden blade to secure the locking plate.
  • this alternative is only applicable if the blade is made of sufficiently soft wood.
  • the interlocking face 34 features raised interlocking patterns 36 that are regularly repeated identically across the entire upper surface of the locking plate 30.
  • the interlocking face 34 of a locking plate 30 is thus designed to be fitted into the interlocking face 34 of an opposing locking plate 30.
  • the interlocking patterns 36 are identical on each of the two plates 30 in the assembly. This notably reduces the manufacturing and management costs of the locking plates 30 and simplifies their attachment to the wooden slats 14, 16 by eliminating the need to manage multiple plate models for the same structure 10.
  • the interlocking patterns 36 of each of the two locking plates 30 are designed to allow the two identical locking plates 30 to be interlocked according to a
  • the interlocking direction is orthogonal to the faces 16a, 14b of the wooden blades 14, 16.
  • the interlocking patterns 36 present a succession of hollows 38 and bumps 40, each bump 40 having a shape complementary to that of each hollow 38 to allow the interlocking of one locking plate 30 into the other.
  • the interlocking patterns 36 also have a shape that allows all degrees of freedom of the wooden blades 14, 16 to be blocked relative to each other in a transverse longitudinal plane. More specifically, this means that the interlocking patterns 36 prevent any translational movement of the wooden blade 14, 16 relative to the other in all directions of the transverse longitudinal plane, as well as any rotation of one wooden blade 14, 16 relative to the other about any axis orthogonal to the plane of the blades.
  • Each locking plate 30 is made of plastic.
  • the locking plates 30 are made of recycled plastic.
  • the locking plates 30 are manufactured, for example, by extrusion molding or injection molding.
  • Each blocking plate 30 has dimensions and a shape that allow it not to protrude beyond the contact zone 18 formed by the overlapping of the two wooden blades 14, 16.
  • the dimensions of the blocking plate 30 are substantially the same as those of the contact zone 18.
  • the shape of the locking plates 30 is adapted to cover the entire contact area 18 between two blades 14, 16.
  • the locking plate 30 has the same square shape and dimensions as the contact area 18.
  • the locking plate 30 has the same trapezoidal shape and dimensions as the contact area 18.
  • the locking plate 30 has a shape that allows it to cover the contact area 18 common to all angles " ⁇ " permitted by the patterns.
  • the plate 30 has a round shape when a wide variety of angles are present, a square shape when the wooden slats 14, 16 are intended to be arranged, or a trapezoidal shape.
  • the interlocking pattern 36 has an alternation of bumps 40, which extend above a median plane 42, and hollows 38, which extend below said median plane 42, as is particularly visible in the cross-sectional view of the [ Fig. 11 ].
  • the hollows 38 and the bumps 40 of an interlocking pattern 36 are arranged adjacent to each other.

  • Each hollow 38 is more particularly surrounded by a continuous alternation of cols 41 and adjacent humps 40 all around its perimeter.
  • Each interlocking motif 36 consists of a bump 40 and a recess 38, the interlocking motif 36 being repeated regularly in at least two different directions across the entire interlocking face 34.
  • Each bump 40 has a vertex 44.
  • a height "h" of the bump 40 is defined as the vertical distance between the median plane 42 and the vertex 44 of the bump 40.
  • Each cavity 38 has a bottom 46.
  • the depth "p" of a cavity 38 is defined as the vertical distance between the median plane 42 and the bottom 46 of the cavity 38.
