Definitions
- the present invention relates to a walkway for crossing obstacles, in particular trenches during road works.
- Pedestrian walkways allowing the crossing of obstacles such as trenches or other types of obstacles are known.
- Some made of oxycut steel sheet have a relatively high weight of 80 to 200 kilos and require handling by means of a lifting machine and therefore the presence of several people for their installation. Therefore, they have two drawbacks, namely a high cost and dangers in particular the risk of crushing during their use.
- Another solution is to use wooden bastings or floors in the form of elements with a thickness between 30 and 50 mm. These elements have a fairly short lifespan and do not facilitate the passage of wheelchairs or strollers.
- a final solution consists in filling the trenches at noon and in the evening with an embankment, which eliminates any risk of falling inside said trenches but generates a significant additional cost.
- the object of the present invention is therefore to propose a gateway of a new type allowing the passage of trenches without risk of falling, the assembly being installed in a simple and rapid manner without any particular handling machine.
- Another object of the invention is to be able to generalize the use of railings by proposing a device for rapid assembly of the railings on said gangway.
- the invention relates to a footbridge for crossing obstacles, in particular trenches during road works, of the type comprising elements forming the floor of said footbridge affecting the shape of plates, such as sheet plates, comprising reinforcing elements, such as pleats, extending over at least part of the length of at least one of the sides of said plate, characterized in that at least one of the floor elements is engaged with at least one guardrail such as a barrier made up of vertical uprights connected by one or more crosspieces, the base of the vertical uprights being mounted integral with a plate comprising at least one reinforcing element such as a fold capable of coming into coincidence with a reinforcement element such as a fold of the floor element and to be covered by it.
- a guardrail such as a barrier made up of vertical uprights connected by one or more crosspieces
- the base of the vertical uprights being mounted integral with a plate comprising at least one reinforcing element such as a fold capable of coming into coincidence with a reinforcement element such as a fold of the floor element and to be
- two adjacent floor elements are assembled by overlapping at least partially to allow the superimposition of the reinforcing elements so that said elements are immobilized in at least one corresponding direction in a direction perpendicular to the longitudinal axis of the reinforcing elements.
- Figure 1 shows a perspective view of a walkway ready to be equipped with a railing according to the invention
- FIG. 2 shows a sectional view of one floor member of the walkway to be introduced and assembled to the railing
- FIG. 3 represents a perspective view of at least two elements of the floor assembled so as to constitute a walkway.
- the bridge object of the invention, is intended to reconstruct a sidewalk in front of a store or any other public or private building.
- This walkway is made up of elements forming the floor 6 affecting the shape of sheet metal or metal plates or any other suitable material which is sufficiently resistant.
- These plates are relatively thin because of reinforcing elements 5 arranged on at least one, part of the length of at least one on their side.
- These reinforcing elements generally consist of folds which extend over the entire length of said plate.
- the reinforcing elements are convex folds 5 extending over the entire length of the longitudinal edges of said plate 6.
- the reinforcing elements 5 of two adjacent floor elements are produced with a identical profile so as to be able to partially overlap when the adjacent floor elements of said gangway overlap as shown in FIG. 3.
- This railing generally of the barrier type, consists of vertical uprights 3 interconnected by means of one or more crosspieces as shown in FIG. 1.
- This type of railing can be an already existing railing and in self-known.
- a plate 1 of variable size Associated with this railing is a plate 1 of variable size, this plate comprising a reinforcing element such as a pleat 5 similar to the reinforcing element of the element 6 forming a floor so that these can be placed in coincidence when the element 6 forming the floor is assembled to the railing.
- the plate 1 and the vertical upright 3 of the railing are generally assembled by welding.
- a plate 7 generally made of sheet metal serving as reinforcement disposed on the face of the plate 1 in contact with the ground so as to avoid any untimely rupture at the fold 5 of the plate by pushing or pulling on the body of the railing.
- the vertical upright 3 of the railing comprises a projecting element 2 such as a cleat arranged so as to provide with the plate 1 a guide groove or housing intended to receive the edge of the element 6 forming a floor equipped with the reinforcement element 5 so that the reinforcement elements 5 of this element 6 come, once the element 6 forming the floor in position on the railing, in coincidence with the folds 5 of said plate 1 so as to immobilize in a horizontal direction the floor element 6 between one of the edges of the fold 5 of the plate 1 and the vertical upright 3.
- the guide groove which forms a cavity and is formed by the plate 1, the projecting element 2 forming a stop and the edge of the fold 5, must therefore have an opening height at least equal to the thickness of the element 6 forming the floor so as to allow the introduction of this element 6.
- the protruding element 2 forming a stop mounted integral with the vertical upright is of a length such that it allows, when the railing is pivoted around one end of the plate 1 in the direction on the side opposite to that comprising the plate 1, that is to say to the left in FIG. 1, that the floor element 6 is lifted from the plate 1 and comes into abutment against the internal face of the element protruding 2 preventing any vertical movement of the assembly.
- This anti-tilting device is reinforced by the fact that when a user crosses the gangway, his own weight constitutes a counterweight to the pushing force which he can exert on the railing.
- bracing element 4 which is arranged opposite the projection 2 on the vertical upright 3 of the railing.
- the plate 1 may constitute an element 6 forming the floor of the bridge.
