Definitions

  • the present invention relates to the assembly of a profile in particular of composite material comprising means for receiving by gluing a means of its connection to a structural element which approaches it laterally or which crosses it.
  • One of the aims of the present invention is to propose means so that an assembly by bonding of a structure comprising sections of sections can be carried out in situ with the care required for this type of assembly.
  • the profile can be accosted by an element having an internal profile substantially identical to the profile of the profile comprised between the two grooves, the bonding taking place between the surfaces with similar profiles facing each other.
  • This bracket constitutes a standardized interface between the profile and any structural element to which it is assembled, the other end of this part being adapted to the element to be connected to the profile.
  • a connecting means preferably in the factory
  • a crinoline ladder comprises uprights constituted by profiles as described above and hoops which themselves consist of a curved bar comprising at each end a stirrup of its connection to the uprights.
  • the crinoline has elements vertical formed by thin bars, connected to the arches by an assembly device comprising on the one hand, two plates each of which is provided on one of its faces with elements for centering the bars which it covers, and elements for mutual angular indexing and on the other hand, means for compressing the plates against each other.
  • the ladder comprises rear fixing lugs, each of them being square, with at the end of one of its wings a fixing stirrup having on the inner face of its two branches, a groove identical to those with which the lateral faces of the uprights are provided and an inner profile similar to that outside of the head of the profile of an upright so that, when the stirrup is keyed to the amount, its interior surface is spaced from the exterior surface by the amount of a set of constant value.
  • FIG. 2 there is shown in section a hollow beam 100 of composite material manufactured by any known method for producing a profile of substantially rectangular section having at least two parallel faces 102 and 103.
  • the beam therefore has two parallel zones 104, 105, 106, 107 of its outer surface in which are grooves 108, 109, 110, 111.
  • the beam may not be equipped with only one pair of grooves, the other end of its section can be arbitrary.
  • the grooves 108 and 109 are arranged back to back as are the grooves 110 and 111 and the outer surface portion, 112 a at the end 101 a and 112 b at the end 101 b , which extends between these grooves is completely convex, that is to say that it does not have a reentrant part inclined as an undercut on a plane P which passes through the grooves.
  • the profile of these surface portions 112 a , 112 b is such that it can be joined by a complementary profile in a movement of approaching the profiles perpendicular to the plane P.
  • Such a complementary profile is indicated 113 on the part 114 of FIG. 2 which constitutes a means of connection of a structural element not shown, coupled to the end 115 of the part 114, to the beam of FIG. 1 by docking. lateral and gluing of the profiles facing each other as illustrated by some of the following figures.
  • the end of the part 114 provided with the profile 113 is here in the form of a stirrup with branches 114 a and 114 b which have grooves 116 and 117 arranged so as to face the grooves 108, 109 or 110, 111 when stirrup covers one end of the section of the beam 1.
  • the end 115 of this piece 114 is equipped with any suitable connection means to be fixed to a structural element, either at the end of this element or at any point of the latter.
  • FIG 3 there is shown a crinoline ladder 1 of which a lateral upright 2 is only visible. To these uprights 2 are fixed rungs 3 and lugs 4 for coupling the ladder to a support structure 5, for example a civil engineering infrastructure.
  • the amount 2 is shown in section from which it appears that it has the structure of a hollow beam.
  • the material which forms this amount is a composite material manufactured by any suitable process (extrusion, pultrusion).
  • the section of this upright has three parts, namely two heads 10 and 11 similar to rail heads and a central part 12, narrower in which the bars are located 3.
  • Each head is bounded laterally by two lateral faces 13 and 14 in which grooves 15 are formed.
  • the four grooves 15 are of semi-circular section and run all the way along the upright.
  • the middle part of the upright is itself provided with place in place, regularly spaced, with holes 16 and 17 to receive a rod end 3.
  • the hole 16 which is on the inside of the upright is of a diameter (or more generally of a section if it is not circular) equal to that outside the bar.
  • the section of the external orifice 17 is equal to that of the interior of the bar 3 which is tubular.
  • stirrup 19 for fixing a horizontal hoop 6 of a crinoline to the upright 2.
  • This stirrup 19 which is shown in more detail in FIG. 6, has two branches 20 and 21 whose spacing is slightly greater at the distance separating the faces 13 and 14 of each upright.
  • the inner surface of these branches is hollowed out with a groove 22 and 23 of semicircular section.
  • Figure 6 shows the part of the stirrup which receives the end of the crinoline arch.
  • This part comprises a recess 27 whose dimensions are in depth and in width, identical to the thickness and to the width of the flat bar 6 which forms the arch.
  • the fixing is carried out by gluing (possibly reinforced with a transverse broaching).
  • This thin bar is preferably made of composite material comprising longitudinal fibers.
  • the coupling leg 4 of the ladder forms a square, a wing of which carries at one of its ends, in one piece, a fixing bracket 28 which has the same provisions as those described with regard to the bracket 19
  • the tab 4 has a mortise 29 which, with the other mortise of the symmetrical tab, constitutes a slide for a panel 30 for blocking access to the rear part of the ladder, in case it would be accessible.
  • the presence of such a panel forms an anti-intrusion device for the area to which the ladder leads.
  • the tab 4 is produced by extrusion. Its length, taken along the upright, can be variable and, in the case where an anti-intrusion panel is put in place, each tab 4 can be of continuous length to form with the panel a closed housing behind the ladder.
  • Figure 7 is a sectional view of the piece 9 for connecting a hoop 6 of a crinoline with a vertical element 8 (stringing element) of this crinoline.
  • this element 8 is curved (tiled) in the transverse direction. This bending is obtained naturally during manufacture when the bar is made of composite material, by distributing the fibers, in its section, in a non-homogeneous manner. If more fibers are placed in the vicinity of one face than in the vicinity of the other face during the polymerization of the resin, the less charged face undergoes a greater shrinkage than the other, which leads to curling.
  • the part 9 is in two parts 31 and 32.
  • the part 31 is a plate of which an outer face is smooth while its other face has two parallel ribs 33 spaced apart from the width of the arch 6 and a tubular lug 34 whose length projecting from the face of the plate is greater than the thickness of the arch 6.
  • the other plate 32 also has two parallel ribs 25 to frame the threading element 8 and to cooperate with the ribs 33 of the other plate in order to index them angularly with respect to each other when they are engaged with the crinoline elements.
  • the ribs 35 may for example extend beyond the ribs 33 of the plate 32 and comprise at this level a projecting part fitting behind each rib 33).
  • the plate 32 also includes a tubular lug 36 to accommodate the lug 34.
  • the crinoline elements 6 and 8 are provided with orifices 37 whose diameter is equal to that of the exterior of the lug 36.
  • the central orifice of the lug 34 is opposite an orifice 38 formed in the plate 32, at the bottom of the lug 36, for the passage of a compression element of the assembly such as a rivet .
  • the stirrup 19 can, by being mounted on the rear face of the uprights and so as to make an acute angle with the plane of the ladder (the crinoline stirrups make an obtuse angle), constitute a support for a curved panel coming to "dress" the rear face of the ladder.
  • Parts having this assembly stirrup can constitute supports for articulation axes of access locking panels, pivoting lids for closing the upper or lower access of a crinoline, or supports for platforms. sliding or non-forming forms forming a rest stage ...
  • each stirrup has in its wall an injection orifice for the glue to be put in place in the clearance between the parts to be assembled.
