Definitions

  • the present invention relates to the production of floors for walkways and more particularly suspended walkways.
  • the object of the present invention is to produce a floor for such a gangway, which is made without welding in order to reduce the cost, to simplify assembly, and to avoid the technical constraints of welding.
  • the structures concerned are advantageously made of aluminum, given the weight gain obtained by the use of this material.
  • the welding technique has troublesome and costly consequences.
  • the welding operation results in an annealing effect on the zone concerned partially but notably neutralizing the improvement in elastic limit obtained by heat treatment of the quality of aluminum used for this purpose.
  • any weld increases the risk of corrosion and requires, to limit these risks, a strict and costly quality control procedure, to which is added the cost of qualified personnel.
  • a modular walkway floor is characterized in that it is composed by the seamless assembly of two plinths, a set of base elements and two end crosspieces, said plinths being constituted by profiles which each have a lateral profile receiving the lateral ends of the basic elements, which lateral profile has, according to a preferred embodiment, at least one projecting part fitting into at least one corresponding notch of these basic elements in involving these in the transverse rigidity of the gangway, the end crosspieces being fixed at the end of the plinths by at least one fixing point on each plinth, ensuring the consistency of the assembly.
  • Each plinth profile has at least one hollow lower longitudinal side profile which serves as a housing for an element intended to connect the plinth to the two end crosspieces or to other parts of the gangway.
  • This lateral profile is preferably arranged on the outside of the gangway and, if it is unique, at the bottom of the plinth. It is hollow and may preferably, but not necessarily, have a closed tubular section.
  • the profile receives in this case, at each end and over an appropriate length, a tapping intended to receive a screw to connect it to the corresponding end transverse element, as well as possibly to a guard jamb. -body arranged above said plinth.
  • a rod threaded at least at its ends, is passed through said profile over the entire length thereof and protrudes at each end to serve as a nut connection as described above.
  • the nuts located at the two ends of the threaded rod are tightened against the ends of the hollow profile to place the baseboard in a prestressed situation.
  • This tightening can be carried out by means of the transverse end elements previously put in place.
  • the threaded rod can be replaced by a cable on the ends of which are fastened clips allowing an equivalent blocking, with the same prestressing effect.
  • the hollow profile located at the bottom of the plinth can be lined with a parallel hollow profile located at the top of the plinth and making it possible to reinforce the bonding effect of the first profile.
  • the assembly described above constitutes a rigid floor assembly obtained without welding of its components which is in particular capable of being connected to railings and stirrups to form a gangway, and in particular a suspended gangway.
  • This assembly also makes it possible, in a simple manner, to preload the bridge.
  • the floor according to the invention consists of two lateral plinths 1, of a series of modular transverse elements 2 constituting the base of the floor, and of two transverse end elements 3.
  • FIG. 1 shows the respective arrangement of these elements with a view to their assembly.
  • Each plinth 1 is designed so as to constitute, in association with the other plinth, a connecting element for the basic transverse elements 2 between them and between the basic transverse elements 2 and the two transverse end elements 3.
  • each plinth 1 is constituted by a profile which comprises, towards the inside , a hollow lower longitudinal side profile 4 intended to serve as a housing at the lateral end 5 of the base elements 2 by wedging them upwards as well as downwards. It is understood that the basic transverse elements 2 are engaged longitudinally by sliding in the said lateral profiles 5 of the plinths 1.
  • the plinth profile 1 has two hollow longitudinal side profiles which are parallel to one another, one of which 6 is disposed at the bottom and the other 7 of which is disposed at the top of the profile.
  • Each profile 6,7 receives, at its two ends 8,9 and over an appropriate length, a thread intended to receive a screw 10.
  • Each of the basic transverse elements 2 is constituted by a metal sheet whose transverse edges 11 are folded back to take a U shape, while its lateral edges 5 are intended to engage and slide in the interior profiles 4 of the plinths 1.
  • each plinth 1 has on its underside projections 13 intended to engage in corresponding notches 14 formed in the lower part of the base elements 2 so that all the basic elements 2 cooperate over its entire length at the connection of the two sides of the floor.
  • the two transverse end elements 3 seamlessly connect the two plinths 1 at each of their ends.
  • These transverse end elements 3 have a U-shape, the branches of which allow a rigid connection with the railings and the plinths. As shown in FIG. 2, this connection is ensured by the screws 10 passing through appropriate openings 15 of the branches of the transverse end element and being screwed into the threaded ends 8,9 of the profiles 6,7 of each plinth 1.
  • connection between the baseboards and the transverse end elements is not ensured by screws, but by a threaded rod or a cable passing through each profile of the baseboard and whose blocking at each of its ends makes it possible to exert a pre-stress effect on the plinth.
  • the floor assembly thus assembled shown in FIG. 5, constitutes a rigid assembly obtained without welding, and which is capable of being connected to railings and stirrups to form a suspended gangway.
  • FIG 6 there is shown the assembled floor, which has received a pair of railings 16 shown in dotted lines. As can be seen, the jamb 17 of the railing is fixed by the screw 10 joining the transverse end element 3 and the plinth 1.
  • FIG. 7 a variant is shown according to which the U-shaped transverse end elements 3 are extended upwards to improve their connection with the railings 16 and to form stirrups allowing the junction between several gangway modules.
  • At least one of the transverse end elements 3 could also be extended upwards to form a suspension bracket (not shown).
  • each plinth 1 there is provided (see in particular Figures 4 and 8) at the upper part of each plinth 1 an attachment profile 18 which cooperates with a corresponding profile 19 provided in the bottom rail 20 of the railing 16.
  • the end legs of the railings are fixed on the corresponding branches of the end crosspieces, as described with reference to Figure 6.
  • the lateral external profiles 6, 7 of the plinth 1 are configured so as to present facing parts 21 forming slides which allow a plate to be fitted by sliding between the two profiles (not shown in the drawing) bearing inscriptions or serving as a support for accessories.
