Definitions

  • the present utility model relates to a grid walkway of the type comprising parallel equidistant strips, on the edges of which are attached a mesh and a number of rods which rest on the grid and run perpendicular to the strips.
  • Grids of this type are widely used to provide walkways spanning open spaces.
  • the assembly formed by the strips and rods constitutes the load-bearing element of the grid.
  • the purpose of the mesh is to reduce the size of the open spaces of the grid.
  • the mesh is fully flat and is welded to and rests on one of the longitudinal edges of the strips.
  • the rods rest on and are welded to the mesh.
  • the load-bearing surface of the grid is defined by the rods, which extend beyond the mesh to define a discontinuous support surface that may be uncomfortable and not very safe.
  • the object of the present invention is to solve the aforementioned drawbacks with a grid of the type described with a nearly continuous support surface, thus providing a safer and more comfortable walkway.
  • the mesh of the invention is provided with externally concave deformations between consecutive strips at the position of the rods, which deformations house said rods. These deformations and the rods are embedded in the strips at the crossing points with said strips, at the position of the corresponding supporting edge.
  • This arrangement provides a walkway defined at least by the mesh segments, which are not deformed and which rest on the edges of the strips, and by the rods.
  • the walkway provided by this grid is nearly continuous, and is only interrupted by the small spaces between the deformations of the mesh and the rods.
  • the mesh can consist of a drilled plate or by an expanded metal plate, with a weight and cost much lower than that of the drilled plate, without detriment of the strength of the assembly while offering a greater ventilation surface.
  • Figure 1 is a perspective view of the grid in accordance with the invention, including a mesh made from drilled plate.
  • Figure 2 is a sectional view of the grid along the line II-II of figure 1.
  • Figure 3 is a sectional view of the grid, perpendicular to the sectional view of figure 2, along the line III-III of figure 1.
  • Figure 4 is a perspective view similar to figure 1 showing an alternative embodiment.
  • Figure 5 shows an enlargement of a segment of the expanded metal plate of the grid of figure 4.
  • Figure 6 is a sectional view of the expanded metal plate along the line IV-IV of figure 5.
  • the drawings show a grid formed by parallel and equidistant strips, labelled by the number (1), with a mesh (2) placed on one of the longitudinal edges of said strips, and above this rods (3) which run perpendicular to the strips (1).
  • the rods (3) are embedded in the strips (1) at the edge by which they are supported.
  • the mesh (2) is provided where it meets the rods (3) with upper concave deformations, labelled by the number (4), as may be clearly seen in figure 3. These deformations are deep enough to house the rods (3).
  • the deformations (4) and the rods (3) are embedded in the strips (1) at the points where they cross said strips, at their supporting edge.
  • the load-bearing surface or walkway provided by the grid is defined by the un-deformed segments (5) of the mesh (2), which rest on the edges of the strips (1), and by the rods (3).
  • This surface is nearly continuous, with the exception of the small spaces or recesses (4) on either side of the rods (3).
  • a walkway is provided which is both more comfortable and, more importantly, safer as there are no elements which jut out of the walkway surface to create an unsuitable support surface which could cause a person to stumble while walking on the grid surface.
  • Figure 1 shows a grid in which the mesh (2) consists of a drilled plate.
  • this grid could also consist of an expanded metal plate, as shown in figures 4 to 6, with a lower weight and cost than drilled plate.
  • This expanded metal plate allows to obtain grids in which the load-bearing element is also the strips (1) and the rods (3), while reducing the size of the surface openings by the expanded metal mesh (6), figures 4 and 5, which has small openings (7) defined by ribs (8) with a small cross-section.
  • the construction and manufacture process of this expanded metal plate are known.
  • the arrangement on the grid of the expanded metal plate (6) is identical to that of the drilled plate in figures 1 to 3, that is, it is deformed under the rods (3), as shown in figure 3, as it is embedded with said rods in the strips (1).
