Definitions

  • the invention relates to a method of anchoring or building foundations for any device such as for example a building element, an element retained by a cable or a pulley or for a mechanical device such as a winch or else finally for a platform or an access road, all these elements being intended to be fitted out in a wooded environment.
  • one or more tree stumps already felled suitably chosen for their provisions relating to and in relation to the nature of the element, for example of construction, the anchoring and the foundation from which they are intended.
  • the upper face of the stump that is to say in fact the plane according to which the tree has been cut, undergoes a rough dressing, which can be carried out in a horizontal plane or in an inclined plane in the case where the nature of the forces to which the strain will be subjected is compatible with such an inclined arrangement.
  • a carrier or retaining element made in principle of steel and which is secured to the stump, for example using lag screws passing through suitable openings, arranged in the base of said element.
  • the base of the carrier or retaining element is constituted by a base plate which has the said fixing openings intended to be crossed by the lag bolts.
  • the base plate is integral with a plurality of metal plates, the planes of which converge towards a mast element of short length, the axis of which substantially coincides with the edges of the dihedrons formed by said plates. to which they are joined for example by welding according to one of its generator.
  • These converging plates are preferably in the shape of a right-angled triangle, the two sides of the right angle of which are thus welded respectively to the base plate and to the mast.
  • the latter carries at its end connecting members capable of engaging with the elements to be supported or retained, this action possibly being carried out by means of organs interposed such as cables, uprights or beams, one of the ends of which engages said connecting members.
  • the supporting or retaining members and may be constituted by simple openings made in the converging plates which, in the latter case, may be directly connected to each other by welding without it there should be a mast element to ensure this junction.
  • the carrier element is more particularly intended to support a device of significant weight such as a residential construction for example
  • a certain number of strains are chosen so as to be distributed in a suitable manner under the element of construction to be supported and each of them is preferably erected in a horizontal plane in order to avoid the tendency to lateral sliding which could result from fixing on stumps with inclined upper face.
  • the horizontal planes in which the upper faces of each strain are drawn up can be any, that is to say not confused, the horizontality of the lower face of the building element then being ensured.
  • the choice of masts or supports of different lengths; these masts or supports can possibly be designed in adjustable length,
  • the cutting plane will be at a level where the grain of the wood is regular and or the installation of bottoms will cause a tendency to form longitudinal slits along the grain of the wood.
  • the anchoring device which has just been defined is particularly suitable for mooring aircraft likely to remain in hovering flight such as helicopters or airships to which the it is sometimes used to transport loads or evacuate tree trunks in mountainous sites with difficult access.
  • Figure 1 is a perspective of a tree stump to which is attached a carrier or retaining element according to the invention.
  • FIG. 2 is an elevation view, partially cut away and in section, of a carrier or retaining element similar to that of FIG. 1, in a direction perpendicular to the plane of two opposite converging plates,
  • FIG. 3 is a view similar to FIG. 1 of a variant
  • FIG. 4 is a partial view shown in another position, of the variant of FIG. 3,
  • FIG. 5 is a view of another variant in which the carrier element is secured to a stump raised in a horizontal plane and supports a construction element shown with cutaway,
  • Figures 6 and 7 are views respectively in perspective and by the lateral edge de.droite, of an inclined panel intended to support solar collectors of electric energy, the ground being represented diagrammatically in section, substantially at the level of said edge lateral,
  • Figure 8 is a view similar to Figure 7 showing the construction of a horizontal platform on sloping ground
  • FIG. 9 is a schematic and simplified perspective of a device similar to that of FIG. 8,
  • Figure 10 is a view similar to Figure 1 of another variant and FIG. 11, also a view of another variant of FIG. 1, relating to a holding element intended for mooring an aircraft.
  • FIG. 1, 1 designates the upper face of a stump (Sl) of a tree felled beforehand, this upper face having been summarily erected so as to receive, in contact with it, a base plate 2 of a carrier element generally designated by (Pl) and consisting, on the one hand, by four plates 4 to 7, attached by welding to the plate 2 and converging towards a mast element 9. of low height on which they are also attached by welding so as to form the same number of dihedrons.
  • each of the plates 4 to 7 is in the form of a triangle.
  • the base plate 2 has a plurality of openings 3a suitably distributed, each crossed by a lag screw 3 of which only the hexagonal head is visible in FIG. 1, one of the lag screws not having been shown so to allow a better representation of one of the openings (3a).
  • the strain S1 was prior to the installation of the lag screws. (3), subjected to a treatment by injection of an anti-fungal and / or insecticidal product (such as for example using the product known commercially under the name of "Xylophene" and / or a plastic material in a liquid state capable of invading the mass of the strain proper and its roots.
  • an anti-fungal and / or insecticidal product such as for example using the product known commercially under the name of "Xylophene" and / or a plastic material in a liquid state capable of invading the mass of the strain proper and its roots.
  • the mast 9 can carry, in any suitable way and in particular as will be illustrated in the following figures, any constructive, support or retaining elements adapted to the requirements of the methods according to the invention.
  • FIG. 2 highlights in particular the ability of such an element to oppose, by its lag screws 12 passing through the openings 12a of the base plate 11 in contact with the upper face 10 of the strain S2, with any tilting in one direction or the other, under the stress, for example, of the traction exerted on a cable 17 which comes into engagement with the hook 16b of a turnbuckle 16 which crosses a loop or eye formed at the end of said cable, the other hook 16a of the turnbuckle being engaged in one of the openings 15.
  • FIG 2 there is a tie rod 20 formed by a metal strip having an opening such as 22a at each of its ends; one of these openings is crossed by a bolt 21, which, in cooperation with a suitable nut not visible in the figure, achieves the fixing of this strip on the support while after having produced a twist of the strip of a amplitude of approximately 90 ° at 20a, the aperture 22a at the other end is crossed by a lag screw 22 screwed into the lateral face of the strain S2.
  • the installation of lag screws such as 22 which can, obviously, have a length greater than that suggested by FIG. 2, may be optionally provided in addition large number and / or provided for each of the converging plates such as 13, 14, makes it possible to achieve an extremely efficient fixing of the support, in particular when the latter has to withstand efforts of transverse direction relative to that of the edges of the dihedrons formed by the converging plates.
  • the plates 13 and 14 are assumed to be substantially in the same plane; it thus appears that, for reasons of simplification of the drawing, we have omitted to represent the plate which is normally located substantially in the bisector plane of the two plates 13 and 14, such as the plate 5 relative to the plates 4 and 6 in Figure 1.
  • the mast element 18 shown in Figure 2 illustrates another possibility of use.
  • this mast is constituted by a metal tube welded to the vertical edges of the converging plates and which constitutes, by its upper part, a female ferrule intended to receive a male ferrule 19a formed at the lower extreme part of a mast 19, of any length, which abuts, by its lower end edge, against the upper end edge of the element 18.
  • the mast element 19 can be used for a wide variety of purposes; in particular, it can act as a support pillar for any supported element, with which it engages by its upper end; it can also receive, in known manner, clamps for tubular scaffolding such as the collar 35 of FIG. 3 which holds the tubular beam 34.
  • the mast element 18 can also, as in the context of the support variant 101, shown in FIG. 11., carry at its upper end a lashing eye 100, for example screwed into its upper part suitably threaded internally with tightening of a locking lock nut 100a.
  • This embodiment is particularly suitable for retaining a cable 103, the end of which forms a loop 102 engaged in said eye and which is more particularly intended to withstand tensile forces of substantially vertical direction such as for example the forces resulting the mooring, by the other end of the cable 103, of an aircraft such as an airship or a helicopter called to stay temporarily in hover over the stump area to, for example, deposit or remove a load.
  • tensile forces of substantially vertical direction
  • an aircraft such as an airship or a helicopter called to stay temporarily in hover over the stump area to, for example, deposit or remove a load.
  • several strains arranged for example substantially along the vertices of a triangle and each carrying such a retaining element, could be used so as to make a
  • the end of the mast 28 is threaded, in a manner which has not been shown, and receives, by screwing, a ring 29 having an upper edge 29a of smaller section arranged, so as to retain the foot 30 of a ball joint 31 which cooperates with a ball joint cage 32 correspondingly shaped, arranged at the lower end of a mast element 33 which can wear any device necessary for the construction of a support carcass including a tubular element 34, fixed to the mast 33 by a collar system 35, only shown.
  • FIG. 4 highlights the case where the cut made on the strain S4 has determined a very inclined upper face 41.
  • element P4 similar to element-P3, on which the base plate 40 carries three converging plates analogous to the plates 24 to 26 of FIG. 3, which support, perpendicular to said plate 40, a mast element 42 on which the thread of the end portion 43 has been shown.
  • FIG. 6 and 7 show, very schematically, the arrangement, in the middle of a wooded site, of an inclined panel 63 intended to support photoelectric solar energy collectors which have not been shown. It can be seen that, in order to fix the panel 63 using the beams 61 carried by the bearing elements 62, any of the various strains S6 to Sl4 has been chosen, the strains S6 to - S11 as well, of course, as a number of other strains hidden by the panel 63 and which have not been shown.
  • the stumps are of variable height above the ground and the panel 63 is fixed by adapting in each case, the length of the beams 61, for example in the manner which is briefly shown in FIG. 3.
  • FIG 8 there is shown a schematic example of building a horizontal platform 80 on an inclined ground T which carries a number of strains of different heights such as S15 to S18.
  • Platform 80 is supported through of a number of carrying masts 81 connected together, in a manner well known in the field of tubular scaffolding, by the beams 82, 83, 84.
  • Figure 9 shows, in schematic perspective, a platform similar to Figure 8, a number of support elements such as vertical masts or connecting beams have only been shown for the sake of simplification of the drawing in which no figure reference has been made given its merely illustrative nature with respect to the device of FIG. 8.
  • FIG. 10 illustrates a variant in which, on the upper face 90 of a supposedly upright stump, has been attached using lag screws such as 92, a base plate 91 which carries a tubular element 93 of section square in which the pillar 94 has been adjusted, of corresponding section.
  • the pillar 94 could be used for example as a constructive element of a residential element, or even a simple awning.
