Definitions

  • the present invention relates to a flat assembling element.
  • the invention also relates to an assembling arrangement that is formed from one or more flat assembling elements.
  • timber is increasingly being used to build various structures. Advances in transformation and prefabrication processes as well as the benefits of using timber in terms of sustainable development objectives mean that construction projects that use timber have a particular advantage.
  • Timber is also associated with other materials such as concrete, polymer materials, metals, glass and other materials.
  • the field of floor slabs is experiencing rapid change based on the use of seasoned solid planks in an all-timber system or mixed system with timber associated with linked concrete in order to achieve long spans.
  • Document DE-1.609.888 describes a floor structure comprising a primary structure made of longitudinal parallel boards, at both ends of which several battens are located in order to create an I-shaped profile.
  • the longitudinal boards form a central web that makes up the thickness of the floor and gives it inertia and have compressive and tensile reinforcement in the form of one or a plurality of battens that are symmetrical on the upper part and the lower part.
  • a floor structure secured by secondary joists is placed on the boards.
  • Document PL-170.890 describes a structure made of parallel boards that are laterally secured by counter-braces. A horizontal board intended to support an upper lay of concrete is placed between two parallel boards.
  • Document EP-1.323.876 discloses a caisson made of two substantially parallel boards connected by longitudinal counter-braces.
  • the counter-braces are inserted in an upper longitudinal batten for compression forces provided at the level of the upper plate and in a lower longitudinal batten for tensile forces provided at the level of the lower plate.
  • Document WO-02/31.283 discloses a prefabricated floor element consisting of a caisson that includes an upper cross-band panel that is used as a compression cover.
  • the upper panel is placed on several central boards, the base of which includes one or two offset battens. These central boards act as a spacer in order to give the caisson inertia.
  • This system is merely a simple prefabricated caisson and does not allow any version other than the described caisson with boards and a panel.
  • the central board with its batten(s) does not form a beam.
  • the performance of the caisson is substantially equal to the inertia of the central boards.
  • the two lateral battens do not reinforce the actual beam.
  • the panel must even be notched in order to properly fit the tip of the board and in order to form an indissociable whole.
  • Document DE-195.37.298 describes an arrangement made of wood consisting of a succession of parallel boards arranged vertically and being alternatively slightly offset in the vertical plane in order to build self-supporting roofing panels. At the same time, these panels constitute the internal frameworks of the space located underneath the roof. However, the loads applied must be evenly distributed and the spans obtained remain small and of the order of 3 m to 5 m.
  • Document FR-2.777.112 discloses an association of a layer of concrete poured over boards arranged vertically and slightly offset in the vertical plane in order to be able to accommodate a transverse fastener that immobilises the concrete on the wood. With this arrangement, spans of 7 m to 8 m are possible for standard floor slab loads equal to 300 kg/m 2 .
  • Document EP-1.149.213 discloses parallel boards placed on edge with a distance between offset boards up to the technical limits of the composite section. The thickness obtained for the arrangement makes it possible to significantly increase the clear span without requiring any intermediate support.
  • An upper panel is used to stabilise the boards against buckling and constitutes the floor of the upper story.
  • One main problem that the invention aims to solve is to perfect an assembling element capable of forming an arrangement of the horizontal floor slab or vertical wall type that is both simple and economical in terms of the quantity of boards required.
  • the second problem is to produce an element that, by virtue of its design, makes it possible to have clearances or voids in order to insert the shafts, pipes and wiring of a building.
  • the third problem is to devise a flat element made of wood that has a satisfactory ability to absorb mechanical deformation.
  • the fourth problem is to obtain a 2 or 3 dimensional arrangement that integrates one or more flat elements.
  • an assembling element that defines a plane comprises primary and secondary structures which are positioned substantially in parallel to the plane.
  • the assembling element is characterised:
  • a separate beam formed from at least two offset boards, constitutes a high-performance primary structure.
  • These beams given the special layout of their boards, are concentrated structural elements.
  • the boards of each beam are laterally offset, i.e. relative to their width. Also, if the boards happen to swell because of humidity at the construction site, this is no longer a problem because the entire gap on each side is available to allow expansion.
  • the association of the beams with the secondary structure constitutes the flat element.
  • the presence of the secondary structure above all the beams made of boards makes it possible to absorb the mechanical stresses exerted on the element thus formed.
  • the flat element may comprise a plate capable of being secured by the two opposite-facing boards each located on the edge of each of the separate adjacent beams.
  • the plate may be freely located at various levels.
  • the plate, the boards and the secondary structure delimit an enclosed space that constitutes a caisson.
  • These plates have an architectural function, for example for rendering the ceiling and sometimes have a technical function in terms of acoustics or fire resistance.
  • the interior is understood to be the side that faces the boards that are not offset or faces the secondary structure.
  • the exterior is understood to be the side that faces the boards that are offset relative to the general plane of the element or is opposite the secondary structure.
  • the element may comprise a plate for joining two separate adjacent beams fixed on an internal edge of two opposite-facing laterally offset boards each located on the edge of each of the separate adjacent beams.
  • the element may comprise a plate for joining two separate adjacent beams fixed on the external edge of opposite-facing boards that are not laterally offset, each located on the edge of each of the separate adjacent beams.

  • the element may comprise a plate for joining two separate adjacent beams fixed on an internal edge of two opposite-facing boards that are not laterally offset, each located on the edge of each of the separate adjacent beams.
  • the assembling element may comprise a part for joining two separate adjacent beams capable of being fixed on the exposed surface of two opposite-facing laterally offset boards.
  • This connecting part may be formed by an alternating sequence of boards and spacers that are laterally offset at right angles to the plane. These boards and spacers give the connecting part a crenellated appearance that is substantially similar to the appearance of the beams with an alternating sequence of offset board and non-offset board.
  • the assembling element may also comprise a part for connecting two separate adjacent beams fixed on the exposed surface of two opposite-facing boards that are not laterally offset.
  • This connecting piece may be formed from boards that are laterally offset at right angles to the plane and positioned at various heights like a staircase. These offset boards give the connecting piece a crenellated staircase-like appearance.
  • the beams may comprise an upper strip that is fixed on the internal edge of the boards that are not laterally offset.
  • the beams may comprise a localised concrete layer with a precise layout which is poured by filling the gaps delimited by the boards that are not laterally offset and the internal edge of the boards that are laterally offset.

  • each of the beams may comprise an odd number of boards.
  • the secondary structure may be a load distribution panel or a series of battens or other items fixed on the internal edge of the boards that are not laterally offset or on the localised layer of concrete or on the upper strip.
  • This secondary structure element for example for a floor, which is made of panels or beams or wooden square cross section blocks or battens must be continuous over the primary beams so as not to introduce any twisting of the main beams when a concentrated local load is applied between two beams.
  • the secondary structure may also preferably be a layer of concrete poured over the plate and covering the separate beams.
  • this high-performance beam made up of several base boards can be reinforced by a layer of linked concrete located in the upper part in order to reinforce the compression area.
  • the assembling element may favourably comprise several fasteners inserted into each separate beam perpendicular to the longitudinal axis of the boards.

  • one board out of two is alternatively laterally offset, i.e. relative to the width of board ( 3 ), relative to each other at right angles to the plane (P) of element ( 1 ).
  • three boards ( 4 ) are downwardly offset and two boards ( 6 ) are not offset.
  • the three offset boards ( 4 ) grip the two boards that are not offset ( 6 ) in an overlap area ( 5 ).
  • a beam ( 2 ) is prefabricated by using fasteners, screws or nails or pins, metal or wood, or by bonding. Very generally speaking, screws are preferred to other types of fasteners.
  • Beam ( 2 ) consists of an odd number of boards ( 3 ), of five to seven boards ( 3 ) or more, i.e. N boards ( 4 ) arranged on edge and screw fastened and offset as much as possible and N ⁇ 1 boards that are not offset ( 6 ) or N+1 boards that are not offset.
  • the offset between boards ( 4 and 6 ) is 30% to 200% offset relative to contact and overlap area ( 5 ) between boards that are offset and boards that are not offset ( 4 and 6 ) which accommodates the fasteners.
  • the basic materials for building the beams ( 2 ) are solid boards, laminated boards (double or triple layer or reconstituted solid wood), glued-laminated wood or Laminated Veneer Lumber (LVL) panels or plywood or also panels called OSB® (Oriented Strand Board) or any other type of beams based on timber or timber derivatives or reconstituted timber and other materials. It should be noted that these beams ( 2 ) can be completely prefabricated at the factory in order to ensure greater quality, construction under dry conditions and extremely fast on-site builds.
  • a plate ( 7 ) or ceiling panel is placed and fixed on internal edge ( 8 ) of offset board ( 4 ) located at the edge of beam ( 2 ) and therefore facing the corresponding offset board ( 4 ) located on the edge of corresponding adjacent beam ( 2 ).
  • Construction of a flat element ( 1 ) is obtained using previous beams ( 2 ) which occupy roughly 10% to 50% of the surface area and alternate with the non-structural areas of plates ( 7 ).
  • Plates ( 7 ) delimit a caisson through which shafts and other tubes can pass.
  • This element ( 1 ) constitutes a “high ceiling” that reveals the beams that constitute it ( 2 ). Plates ( 7 ) provide the internal finishing for the lower space.
  • Traditional plywood panels can be used for these plates, ceiling panels or cladding ( 7 ).
  • Panels made of synthetic or rigid insulating materials e.g. rock wool
  • these plates ( 7 ) can be selected from a non-flammable material (class MO) or flame resistant material (class Ml).
  • a secondary structure consisting of an upper floor panel or a load distribution panel ( 9 ) is placed on the internal edges ( 11 ) of the boards that are not offset ( 6 ).
  • the continuity of this panel ( 9 ) allows virtually uniform loading of the various upper boards that are not offset ( 6 ) of beam ( 2 ).
  • load distribution panel ( 9 ) associated with element ( 1 ) preferably consists of a wooden panel, preferably of the cross-veneer laminated type, has a strong axis in the direction of its fibres and weak axis in the direction of two or three cross plies.
  • This panel ( 9 ) is screw fastened on separate beams ( 2 ) ensuring continuity over said beams ( 2 ).
  • secondary structure floor panel ( 9 ) is sized so as to be able to support this distributed or concentrated load when it is applied between the two primary beams ( 2 ). All the variations described below offer the same performance with, for example, 50/200 mm boards offset by 120 mm, a beam ratio of 30% (1 ⁇ 3).
  • Flat element ( 1 ) obtained has a load bearing capacity of 6 m to 8 m for a load of 300 kg/m 2 .
  • a second embodiment of the invention see FIG. 3
  • the same solution as that of the first embodiment ( 1 ) is chosen for element ( 12 ) with beams ( 2 ), the three offset boards ( 4 ) and two boards that are not offset ( 6 ) which constitute them and the interposed plates ( 7 ).
  • the upper floor panel ( 9 ) is supplemented by a sound absorber ( 13 ) placed on floor panel ( 9 ) then a finishing layer ( 14 ) that constitutes the finished floor of the upper space.
  • element ( 16 ) comprises beams ( 2 ) in a way that is substantially similar to that of the first and second embodiment ( 1 and 12 ). However, the alternate sequence of component boards ( 3 ) is reversed. Three boards that are not offset ( 17 ) secure two offset boards ( 18 ). Load distribution panel ( 9 ) is placed on internal edges ( 11 ) of the boards that are not offset ( 6 ).
  • the ceiling caisson is made using a plate ( 19 ) suspended at the bottom on the external edge ( 21 ) of the upper lateral board that is not offset ( 17 ) of beam ( 2 ).
  • beam ( 2 ) remains proud relative to caisson plate ( 19 ).
  • Two mounting solutions are preferred, using the clip described in Document EP-1.000.207 which enables concealed fixing or using a triangular batten ( 22 ) that acts as a trim for the fastener and which shows a small cornice in the exposed ceiling. Obviously, other customary fixings are also possible.
  • element ( 23 ) is reminiscent of the first and second embodiments ( 1 and 12 ).
  • Beams ( 2 ) comprise two boards that are not offset ( 6 ) and three offset boards ( 4 ).
  • the load distribution panel secondary structure ( 9 ) is placed on the internal edges ( 11 ) of the boards that are not offset ( 6 ).
  • Plate ( 24 ) is suspended at the lower level on the external edge ( 26 ) of an additional laterally offset lower board ( 27 ) that is placed alongside the offset boards ( 4 ) on the edge of beam ( 2 ). This has the effect of concealing the height of beam ( 2 ) and therefore produces a flatter ceiling.
  • Other solutions can be adopted in order to attach plate ( 24 ). Rabbets or grooves can be made in the board. Rails, brackets or clips can be separately mounted.
  • one element ( 28 ) comprises three boards that are not offset ( 29 ) and four downwardly offset boards ( 31 ). Notches or rabbets ( 32 ) are made in the area where the boards that are not offset ( 29 ) and four downwardly offset boards ( 31 ) overlap. These rabbets ( 32 ) make it possible to reduce the gap ( 33 ) between the boards that are not offset ( 29 ) and between the downwardly offset boards ( 31 ).
  • a plate ( 7 ) is mounted on internal edge ( 8 ) of the boards that are offset ( 31 ) on the edge of beam ( 2 ).

  • Strip ( 34 ) has its strong axis parallel to axis (L) of boards ( 3 ) of these beams ( 2 ). This provides a ⁇ -shaped beam ( 2 ).
  • Load distribution panel ( 9 ) is placed directly onto internal strips ( 34 ).
  • one element ( 36 ) is reminiscent of element ( 23 ) in the fourth embodiment with beams ( 2 ) comprising two boards that are not offset ( 6 ), three offset boards ( 4 ) and plate ( 24 ) suspended on the external edge of additional offset board ( 27 ).
  • An additional plate ( 37 ) is placed on the internal edges of offset boards ( 4 and 27 ) at the edge of beams ( 2 ).
  • a layer of concrete ( 38 ) is poured on plates ( 29 ) and over the totality of element ( 36 ) so as to cover beams ( 2 ) at the level of the boards that are not offset ( 6 ).
  • Concrete ( 38 ) forms the secondary structure and reinforces the compressed upper area.
  • Load distribution panel ( 9 ) is placed on concrete ( 38 ) to ensure finishing.
  • Concrete ( 38 ) is appropriate to the required performance level.
  • the concrete of choice is a high-performance, lightweight concrete containing wood or synthetic aggregates or any other traditional concrete.

  • Localised layer ( 47 ) stops substantially in the middle of the edge of the board that is not offset ( 44 ) on the edge of beam ( 2 ).
  • a plate ( 48 ) is then mounted on this internal edge of the board that is not offset ( 44 ) at the edge.
  • Plate ( 48 ) is used as formwork for screed ( 49 ) poured on localised layer ( 47 ) and between beams ( 2 ) forming a continuous surface.
  • This screed ( 49 ) may or may not comprise reinforcement ( 51 ).
  • a second ceiling can be freely arranged in order to box in the area between two beams ( 2 ) and conceal building technical services.
  • the finishing coat may remain the concrete screed ( 49 ), for example for a tiled finish or for installing an underfloor heating system. It should be noted that screed ( 49 ) is then part of the secondary structure of the floor. Concrete ( 49 ) does not reinforce the load-bearing capacity of basic beam ( 2 ) because concrete ( 49 ) is not connected to beam ( 2 ). In fact, it floats on the secondary panel formed by plates ( 48 ).
  • one element ( 52 ) comprises the same beams ( 2 ) as those in the eighth embodiment ( 43 ).
  • Localised layers of concrete ( 47 ) are poured on the edge of the boards that are not offset ( 44 ).

  • a secondary structure made of continuous tesserae ( 48 ) is fitted on beams ( 2 ).
  • These tesserae ( 54 ) have a resilient sound absorber placed underneath their support on beam ( 2 ) and then accommodate a panel ( 9 ) or a traditional floor or even known solutions according to the current state of the art. This solution may be appropriate in certain industrial settings in order to make the ceiling panel more economical.
  • the space between two load-carrying beams ( 2 ) is therefore not boxed in.
  • one element ( 56 ) has beams ( 2 ) with three boards that are not offset ( 29 ) and four offset boards ( 31 ) as in the fifth embodiment ( 28 ).
