Definitions
- the invention relates to the field of construction, taken in its sense broad, and more specifically the field of construction of various works carried out partly made of wood.
- the present invention is particularly suitable for carrying out horizontal structures, it could also be used when making vertical walls.
- the invention is particularly suitable for carrying out works which are, if necessary, removable, especially in the context of temporary constructions.
- the load per unit area, supported by each beam (3) corresponds to the load distributed on the supporting panel (4) on a width equal to one between axis (e), or distance between beams.
- a first problem which the invention proposes to solve is that of the production of structures which are, if necessary, easily removable, by example in the context of temporary constructions, to take into account ecological constraints requiring reuse of the materials used in a such a frame.
- one of the objectives of the invention is to make it possible to carry out structures that can be dismantled or not, at a lower cost than the production of beams by glue-laminate technique.
- one of the objectives of the invention is therefore to achieve such structures using standard parts, such as 200mm planks of width (h), planks which can be of various length and making it possible to carry out structures, long-range (from 6 to 12 meters), resistant to loads important, very long, and this from elementary planks that can be between 2.5 and 5 meters in length only, or for classic industrial lengths of 2 and 4 or 5 meters.
- standard parts such as 200mm planks of width (h), planks which can be of various length and making it possible to carry out structures, long-range (from 6 to 12 meters), resistant to loads important, very long, and this from elementary planks that can be between 2.5 and 5 meters in length only, or for classic industrial lengths of 2 and 4 or 5 meters.
- offset plank structures can be used to make structures capable of supporting mobile loads, for example structures serving traffic lane, in particular for public works or delivery vehicles used for the construction of buildings intended to be mounted on a slab or platform which would be made from wood.
- a new type construction slab intended to be mounted on a load-bearing structure and capable of support a large load, fixed or mobile, comprising, in a way comparable to the teachings of DE- 195.37.298 above, a basic structure consisting of a plurality of parallel boards, of rectangular section, which are assembled together by nailing or screwing.
- the boards of rectangular section have their axis longitudinal parallel to the plane of the slab, and are alternately offset by one report and this, perpendicular to the plane of said slab.
- the slab according to the invention is characterized in that the basic structure is covered, on at least the entire surface intended to receive the load, with a panel continuous, extending over the entire width of said base structure, fixed at least against the upper surface of the boards of this basic structure, and which allows to distribute the load exerted on said continuous panel on several boards close to those against which is exerted directly the load, this distribution being done according to an axis perpendicular to said boards, parallel to the direction of screwing or nailing of boards between them, the boards being alternately offset by a distance between half and two thirds of their width.
- planks of the basic structure are alternately offset by a distance between half and two thirds of their width (h), which translates, in terms of flexural strength by an increase of 150 to 200%.
- a second panel can be placed under the planks to further reinforce the slab.
- the construction slab according to the invention behaves as the association of a beam constituted by the assembly of the boards, and at least minus a top panel on which the loads can be directly applied.
- the assembly of boards nailed and / or screwed together makes it possible to obtain a beam of width equal to its span, or in other words, a beam extending over the entire width of the slab it supports.
- the offset between two consecutive boards of this structure allows multiply by 1.5 to 2, the bending resistance compared to a beam which would have a height equal to the width (h) of only one of the planks and make it much less deformable by reducing slenderness, a characteristic which is result of the ratio of the span length to the thickness of the slab.
- the configuration given to the plank structure is particularly advantageous in terms of flexural strength and deformability. According to another point of view, such a configuration makes it possible to obtain a resistance mechanical with a saving of material.
- the distribution panel associated with the basic structure will be preferably consisting of a wooden panel, preferably of the “micro-blade” type crossed ", has a strong axis in the direction of the fibers and a weak axis in the direction of two or three folds crossed, said panel being screwed onto the basic structure with its axis strong perpendicular to the axis of the boards of said structured.
- the distribution panel can consist of a layer or plate of concrete that can be poured into the basic structure consisting of offset boards.
- metal rods can be integrated inside the layer of concrete to increase the shear strength as well as the quality of the wood-concrete composite section.
- the slab according to the invention comprises, ensures a distribution, on several consecutive side boards and close to those against which the load is directly exerted, this distribution being made along an axis perpendicular to the boards, therefore parallel to the direction of screwing or nailing of boards between them.
- a waterproofing layer such as asphalt, can possibly be poured on the surface of the distribution panel.
- the distribution panel In the case where the distribution panel is made of poured concrete, it penetrates into the spaces formed between two boards offset at the same level, which improves the bond of the concrete material to the wood, to give a compound inertia, with the concrete in compression and wood in tension.
- each slab has a cutout capable of allowing its arrangement with the beams of the supporting structure.
- a gasket is made at the connection between each panel.
- treatments chemicals can be applied on the surface.
- the invention relates to a building slab intended in particular to be used for the realization of platforms mounted on stilts, but also for the realization of floors, walls or facades of buildings.
- these different piles (10) have support elements (12) intended to receive beams (13) formed in the example illustrated by metal profiles.
- the set of piles (10), different beams (12, 13) constitute what is hereinafter called “supporting structure”.
- the invention relates to the various slabs (15) which are placed on the metal beams (or wooden beams) (13), which are intended to support the large load to be installed.
- This load can be fixed, in the case of buildings or even mobile, if this platform serves as traffic lanes, and in particular for public works and delivery used for the construction of these buildings.
- this slab (15) consists on the one hand, a structure (16) consisting of an assembly of different boards (17) of wood, and secondly, a distribution plate (18) secured to the structure (16) of boards with screws or nails allowing inertia if necessary compound, this principle can also be applied on the underside.
- the slab (15) comprises therefore a structure (16) consisting of an assembly of boards (17) of dimensions standards.
- the various boards (17) constituting this assembly (16) are arranged with their longitudinal axis parallel to the plane (20) of the slab (15).
- the boards (17) are joined together by their width (h). According to one important feature, the boards (22, 23) are alternately offset the relative to each other, and in a direction (Z) perpendicular to the plane (20) of the slab (15).
- plank structure has a height (H) greater than the width (h) of a single board (17), which gives this structure the behavior equivalent to that of a beam much thicker than that of a standard board, this thickness being obtained by shifting the boards.
- the different boards (22, 23) are offset one by compared to others from a distance between half and two thirds of their width (h).
- the complete structure therefore has a thickness (H) of between 1.5 and 1.7 of the width (h) of a board (17).
- the composite beam of thickness (H) constituted by the structure (16) exhibits bending strength properties twice that of that would have a beam of the same width, but of thickness (h) equal to that of a unitary board (17).
- each board (22) is screwed or nailed with the two adjacent boards (23, 24).
- the density assembly means (26) can be chosen optimally, and to distribute the point load (eg truck wheel) on several side boards.
- the slab (15) illustrated in Figure 4 has, above the structure (16) of characteristic boards, a distribution panel (30), which can be made of wood in which case it will preferably be based on a “microlame” type panel having a strong axis in the direction of the fibers and a weak axis in the direction of two or three crossed folds, this panel being screwed with its strong axis perpendicular to the axis of the boards.
- a distribution panel (30) which can be made of wood in which case it will preferably be based on a “microlame” type panel having a strong axis in the direction of the fibers and a weak axis in the direction of two or three crossed folds, this panel being screwed with its strong axis perpendicular to the axis of the boards.
- This panel (30) distributes the loads exerted along an axis perpendicular to the boards (17), therefore parallel to the direction of screwing or nailing boards on several neighboring boards (23, 25).
- such a panel provides an effect slab, laying in both directions of the plane.
- Such a construction method with a panel made up of a microblade cross allows, as shown in Figure 6, to disperse the point charge across the width of the boards.
- a truck wheel (R) transmits a load over an area of 40 x 40 cm 2 .
- the thickness of the panel and its length which can be up to 12 meters, or even more, it is possible to optimize the slab behavior.
- the truck load can be spread over 1.50 m.
- 4 times more boards work on resistance compared to a unreinforced beam mode.
- the cutting forces of the truck wheel are absorbed by the panel and no longer by the screws or nails connecting the boards elementary between them, which eliminates all risks of rutting.
- the screw allowing a tensile force on its axis, the reduction in the number of screws is offset by the friction of the boards level of the contiguous surface.
- the screws give a kind of prestress perpendicular to the boards which improves the slab effect on the direction perpendicular to said boards.
- a structure having very good characteristics can be obtained by using 20 screws per m 2 , with a diameter of 6 mm, length 220 mm while the application of the usual standards would require the use of 40 screws.
- the panel distribution (4) located above the structure (16) of a wooden board can consist of a layer of reinforcing concrete, which can advantageously, but not necessarily, be as illustrated in Figure 5 poured directly onto the structure (16) of wooden planks.
- the concrete interferes in the spaces (42) existing between the offset boards (43, 44), which improves the properties of the slab in the direction transverse, concrete better distributing the point load.
- a section system composed with concrete in compression and wood in traction can be obtained by interfacing connection connectors (200), (201) two materials (screws, lag screws or other), as shown in Figure 11.
- the tiles according to the invention can constitute a platform in itself, or be assembled to make platforms for very large dimensions.
- unitary slabs of 2 meters wide and up to about 40 m long, the length being limited by the transport.
- the boards are nailed or screwed end to end tip by distributing the seals preferentially in the moment zones weak bending.
- Plank lengths of 4 or 5 m allow for a slab on several static supports with a center distance of 6 m and for lower loads up to about 12 meters range.
- two structures (50, 51) of boards assemblies are associated at the level of a beam (52) of the supporting structure.
- the boards (54, 55) of the two supporting structures (50, 51) of each of the panels (56, 57) are cut at their lower edge (58, 59) so that the boards (60, 61) constituting the upper part of each of the assembled plank structures come to rest on the beam (52).
- Screw or lag screw metal connectors (62, 63) are used to joining the two structures (50, 51) of planks to the beam.
- the distribution plate (53) is unique for the two plank structures (50, 51) which are adjacent, but it could be replaced by two independent panels.
- a pressure distributor element is constituted by a layer of concrete (70), and as illustrated in FIG. 8, it can be provided at level of the beam (72) of the supporting structure, of the joists (73, 74) on which rest the lateral ends (75, 76) of the structures (77, 78) of assembled boards. The forces are then transmitted to the main beam the inertia of which can be increased by binding the concrete material to this beam.
- the upper part (81, 82) of the structures (77, 78) of planks is cut so that the concrete layer (70), poured directly over the plank structures (75, 76, 77, 78), forms a cone (83) bearing by its base on the top of the beam (72) of the structure carrier.
- a connector (85) is advantageously provided, the end of which is fixed to the inside of the beam (72) of the supporting structure, and which sees its upper part embedded in the concrete layer (70). This ensures a good anchoring of the layer of concrete to perform a composite action of wood and concrete on the beam main (72).
- FIG. 10 illustrates, for its part, a variant of a slab conforming to the invention in which additional spacers (202) are arranged between two elementary boards offset from the basic structure.
- Such spacers can optionally be made of panels of particles and save planks.
- the distribution panel is sized to take into account of these extra plank spaces.
- construction slab according to the invention can be used not only to make horizontal platforms, slabs, but also to constitute walls or walls of buildings, as illustrated in Figures 12 and 13.
- the wall (100) consists of slabs according to the invention, the structure of assembled boards (101) of which is located inner side of the wall, so as to be visible, while the outer part of the wall consists of a rigid plate (102) intended to distribute the forces over a plurality of boards (103) of the structure (101). This allows, to distribute the forces exerted by the wind, which we know can be particularly important.
- This tray will also serve as a support layer for the finishes (plaster, painting, etc ).
- the slab according to the invention has a distributor plate (110) which comes into contact with the outside half of the boards (111) of the structure (112) of assembled boards.
- This panel can be advantageously spaced to allow natural ventilation boards in case of water infiltration.
- an insulation layer (113) is provided on the inside of the wall of the wall. and is placed on the face (115) of the structure (112) of assembled boards, looking at the inside of the wall.
- This insulation layer (113) is covered with a finishing layer (116) and optionally a barrier layer (117) preventing the passage of steam by insulation direction.
