Definitions

  • the present invention relates to realization of floors for walkways and more especially suspended walkways.
  • gateways are generally made up of various elements assembled on site each of which is made of welded components.
  • the object of the present invention is to make a floor for such a walkway, which is made without welding in order to reduce the cost, simplify assembly, and avoid constraints welding techniques.
  • the structures concerned are advantageously made of aluminum, given the weight gain obtained by using this material.
  • the welding technique has awkward consequences and expensive.
  • the welding operation leads to the area concerned an annealing effect partially neutralizing but notably the improvement of elastic limit obtained by quality heat treatment aluminum used for this purpose.
  • a modular floor of gateway composed by seamless assembly of two plinths, a set of basic elements and two sleepers end, said plinths being constituted by profiles which each have a side profile receiving the lateral ends of the basic elements, which side profile presents, according to a mode preferential, at least one projecting part fitting in at least one corresponding notch of these basic elements by involving these in the transverse stiffness of the gangway, is characterized in that the crosspieces are fixed at the end of the plinths by at minus one fixing point on each plinth in ensuring the coherence of the whole.
  • Each plinth profile has at least a hollow lower longitudinal side profile which serves housing to an element intended to connect the plinth to two end ties or to other parts of the bridge.
  • This lateral profile is preferably arranged on the outside of the bridge and, if it is unique, at the lower part of the plinth. It is hollow and can preferably, but not necessarily, a closed tubular section.
  • the profile receives in this case, at each end and on a appropriate length, a thread intended to accommodate a screw to connect it to the transverse element corresponding end, as well as possibly a guardrail jamb arranged above the said baseboard.
  • a rod threaded at least at its ends, is passed in the said profile over the entire length of it and protrudes at each end to serve as a connection by nut as it says above.
  • the nuts located at both ends of the threaded rod are pressed against the ends of the hollow profile to place the plinth in a prestressed situation. This tightening can be done through the elements transverse end previously installed.
  • the threaded rod can be replaced by a cable on the ends of which are fixed fasteners allowing equivalent blocking, with the same prestressing effect.
  • the hollow profile located at the bottom plinth can be lined with a hollow profile parallel located at the top of the plinth and allowing to reinforce the bonding effect of the first profile.
  • the described assembly above constitutes a rigid floor assembly got seamless from its components which is likely in particular to be connected to railings and stirrups to form a bridge, and in particular a suspended walkway.
  • This set allows for besides, in a simple way, the prestressing of the bridge.
  • the floor according to the invention consists of two side plinths 1, of a series of modular transverse elements 2 constituting the base of the floor, and of two elements transverse end 3.
  • Figure 1 shows the respective arrangement of these elements for their assembly.
  • Each plinth 1 is designed so as to constitute, in association with the other plinth, a connecting element of 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 inwardly has a side profile hollow lower longitudinal 4 intended to serve as housing at the lateral end 5 of the basic elements 2 by setting these up and down.
  • the basic transverse elements 2 are longitudinally engaged by sliding in the said side profiles 5 of plinths 1.
  • the plinth profile 1 has two hollow longitudinal side profiles parallel to each other, one of which 6 is disposed at the lower part and the other 7 of which is disposed at the upper part of the profile.
  • Each profile 6.7 receives, at its two ends 8.9 and over an appropriate length a internal thread intended to accommodate a screw 10.
  • Each of the basic transverse elements 2 consists of a metal sheet whose edges transverse 11 are folded to take a shape in U, while its side edges 5 are intended for engage and slide in the interior profiles 4 of plinths 1.
  • each plinth 1 has projections 13 on its underside intended to engage in corresponding notches 14 arranged in the lower part of the base 2 so that the set of basic elements 2 cooperates over its entire length in the connection of the two sides of the floor.
  • the two transverse end elements 3 seamlessly connect the two plinths 1 to each of their ends. These transverse end elements 3 have a U shape whose branches allow a rigid connection with railings and baseboards. As shown in Figure 2, this link is provided by screws 10 passing through openings appropriate 15 branches of the cross member end and screwing into threaded ends 8.9 of the profiles 6.7 of each plinth 1.
  • connection between the plinths and the elements transverse end is not secured by screws, but by a threaded rod or cable passing through each profile of the plinth and each blocking of its ends allows to exercise on the plinth a pre-stress effect.
  • the floor assembly thus assembled shown in Figure 5 constitutes a rigid assembly obtained seamless, and which is likely to be connected to railings and stirrups to form a gangway suspended.
  • FIG 6 there is shown the floor assembled, which received a pair of 16 figured railings dotted. As we can see the jamb 17 of the railing is fixed by the screw 10 fastening the transverse end element 3 and the plinth 1.
  • FIG. 7 a variant has been represented. that the transverse end elements 3 U-shaped are extended upward to enhance their connection with the railings 16 and form brackets allowing the junction between several modules gateway.
  • At least one of the transverse elements end 3 could also be extended upwards to form a hanger (not shown).
  • each plinth 1 At the top of each plinth 1 an attachment profile 18 which cooperates with a profile corresponding 19 provided in the bottom rail 20 of the railing 16.
  • the end legs of the railings are fixed on the corresponding branches end crosspieces, as described in reference to figure 6.
  • the side external profiles 6,7 of the skirting board 1 are configured to present facing parts 21 forming slides which allow by sliding between the two profiles plaque (not shown in the drawing) with inscriptions or serving as a support for accessories.
