Definitions

  • the present invention relates to a grid allowing shuttering manhole covers, for example.
  • the outer edge of the grid is usually a solid edge coming into contact of the frame and constituting an additional obstacle to passage of water through the grid.
  • the object of the invention is therefore to remedy all of the disadvantages above by proposing a mounting grid elastic in a frame, having all the qualities solidity and reliability, and likely to allow or absorb a maximum amount of water passing on this grid.
  • the invention relates to a grid intended to be mounted in a frame to seal a look of roadway and including crisscrossed bars, at minus one of the end bars of the grid being elastically deformable compared to other bars so that the grid is fixed elastically in the frame, characterized in that said end bar is secured to the grid only by its two ends between which at least one hookable lug is provided in a notch or the like made in the frame.
  • the abovementioned end bar is provided with at least one stop element vis-à-vis the frame and the bar adjacent.
  • the aforementioned lug is located between two stop elements projecting from on either side of the end bar and likely to each cooperate with a corresponding stop provided on the adjacent bar.
  • the grid of this invention is further characterized by a sheet of parallel bars comprising the two abovementioned end bars and comprising, between the transverse bars, studs or the like making protruding towards the outside of the grid.
  • the aforementioned transverse bars form a extra thickness on the sheet of parallel bars, and the stop elements of the two end bars constitute an extension of this extra thickness.
  • the lug integral with the aforementioned end bars cooperates with a ramp associated with the notch in the frame, when placing the grid in this frame.
  • Figure 1 is a plan and top view of a grid according to the invention illustrated in the mounted position in a frame.
  • Figure 2 is a sectional view along line II-II of figure 1.
  • FIG. 3 is another section view of the grid, along line III-III of Figure 1.
  • Figure 4 is a sectional view of the attachment system of the grid on the frame, along line IV-IV of the figure 1.
  • a grid according to this invention comprises essentially a sheet of parallel bars 1 coming foundry with parallel transverse bars 2, the grid being mounted in a frame 3 secured to a roadway (not shown).
  • the sheet of parallel bars 1 has at its two ends a bar 4 elastically deformable by compared to the other bars 1 and allowing fixing removable from the grid on the frame 3.
  • these two end bars 4 are secured to the remaining part of the grid by their two ends 5 only.
  • a lug 6 is provided, better visible in Figure 4, and capable of cooperating with a notch or the like 7 made in frame 3.
  • the frame 3 has a ramp-shaped portion 8 leading to the notch 7 and with which the lug 6 can cooperate, each side of the grid, to allow placement of the grid in frame 3, as will be explained in detail later.
  • each elastic end bar 4 is located between two abutment elements 9 vis-à-vis the frame 3 and the adjacent bar 1. More precisely, as we see in Figure 1, the stop elements 9 are projection on either side of the end bar 4 of so as to cooperate, on the one hand, directly with the edge 3a of frame 3, and on the other hand, with a stop corresponding 10 provided on the bar 1 adjacent to the elastic end bars 4.
  • end bars 4 may struggle elastically between the ends 5 which connect these bars 4 to the grid, it being understood that the stroke of the elastic travel is limited by the stop elements 9 cooperating on one side with the frame 3 and on the other side with the stop 10 of the adjacent bar 1.
  • the parallel bars 1 have, between the bars transverse 2 small studs or the like 11 making protruding towards the outside of the grid.
  • the studs 11 advantageously allow the separation of the nets of water in several nets, as materialized by arrows 12, so the grid will thus offer less resistance to water retention and will therefore absorb maximum amount of water through the interstices between bars.
  • the bars 2 transverse to the bars 1 form a extra thickness 13 on the sheet of parallel bars 1, as can be seen in Figure 2.
  • the elements of stop 9 projecting on either side of each end bar 4 constitute, in a way, a extension of the allowance 13.
  • the extra thickness 13 presented by the bars 2 will form a water barrier flowing on the grid following the arrow marked Y on Figure 1, so that the water will flow to the across the grid between the gaps formed between bars 1 and 2.
  • the nets of water pass over the extra thickness 13 of bars 2, they will then also be broken or separated by the studs 11 of the bars 1.
  • the water as soon as it crosses the frame 3, necessarily falls into the holes formed between frame 3, two adjacent free ends 1a of bars 1 and a bar 2.
  • free ends 1a, 4a advantageously limits the extent of the upper face of the grid, and therefore we diminishes its capacity to allow retention and the sliding of the water.
  • the grid does not include no full outer edge likely to retain water flowing according to the arrows X and / or Y.
  • Frame 3 being put in place and fixed on a roadway for example, just position the grid that comes to be described to the right of the framework.
  • the elastic deformation of the bars 4 will be limited by the stop elements 9 cooperating with the stops corresponding 10 of the adjacent bar. So the elastic deformation of the bars 4 will advantageously which will prevent any deterioration of the wire rack.
  • damage to the bars end 4 will be all the more avoided as the deformation of these bars, in one direction or another, will be done in a way symmetrically at the level attachment points 5 of these bars to the grid.
  • the grid of the invention can include any number of bars, studs such as 11 and cooperating stops making it possible to limit the travel of deformation of the last bars of the grid being understood that the stops can be omitted.
