Description

Gutter element

  The present invention relates to a drainage channel element for a drainage channel for roadways or access roads, consisting of a channel section body with a U-shaped section whose upper horizontal ends of branches are arranged to receive a metal grid or plastic material, said channel body having at least at both ends assembly members of said channel member with one or two other channel elements, one of said ends being provided with at least one male connecting member and the other end being provided with at least one female connector member, said female connector member and said male connector member cooperating with each other by sliding in a vertical plane of said channel members.

  A drainage channel is made by assembling said channel elements. During this assembly, it is important that the stability of the gutter thus formed is maximum to avoid all risks of movement of the gutter elements assembled relative to each other. In particular, in the gutters formed by assembling the gutter elements by sliding in a vertical plane, it was realized that the elements could, nevertheless, still move vertically relative to each other, causing disturbances in the gutter form.

  The present invention therefore aims to provide a channel element that can be assembled in a simple manner to another channel element, by sliding in a vertical plane but remains stable both axially and vertically.

  2 2861758 For this purpose, the invention relates to a drainage channel element for drainage channel for pavements or access roads, consisting of a channel body with a U-shaped section whose upper horizontal ends of the branches are arranged for receiving a metal or plastic grid, said channel body having at least at both ends assembly members of said channel member with one or two other channel elements, one of said ends being provided with at least a male assembly member and the other end being provided with at least one female assembly member, said female assembly member and said male assembly member cooperating with each other by sliding in a vertical plane of said gutter elements, characterized in that the male connecting member is constituted by a rib formed projecting radially at the end of the gutter body, the ridge re presenting preferably at least one locking member such as a recess and the female assembly member consists of a groove formed at the end of the channel body, open towards the inside of said body, said groove having preferably at least one locking member such as a stud, complementary to the locking member provided to the rib.

  Thus, advantageously, the assembly members of the channel elements according to the invention make it possible to guarantee the longitudinal locking of the elements between them but also guarantee the vertical blocking of said elements thanks to the presence of the complementary locking members respectively on the male assembly member on the female assembly member and constituted, for example, by studs and recesses or by any other type of suitable complementary locking members. A drainage channel made from channel elements according to the invention therefore offers improved stability, particularly when the materials are reported in the trenches and then exert a thrust on said channel. This locking of the gutter elements thus advantageously ensures the maintenance of the gutter formed during final setting and leveling.

  Preferably, the gutter body has at least one lateral outlet having either a male connecting member consisting of a rib formed projecting radially at said outlet or a female connecting member consisting of a groove formed at said outlet, cooperating by vertical sliding with the complementary assembly member of another channel body.

  Preferably, each side outlet has a lidding having a circumferential thinning and a cross-shaped weakening for directing a shock wave during uncapping. Thus, when it is desired to connect a channel element to a lateral outlet, this sealing is destroyed, the weakening in the form of a cross and the thinning facilitating this uncapping.

  When the assembly member provided on the lateral outlets is constituted by the male assembly member according to the invention, the outlet can receive a universal upstream / downstream and lateral birth bottom in order to connect the evacuation tube in all directions. potential connection points: upstream, downstream, lateral.

  In addition, when assembling channel elements at angles, T, cross 20 through the side outlets, the locking of the channel elements then intervenes along three axes reinforcing the stability of the gutter thus formed.

  Preferably, the gutter body has hollow reinforcing ribs on its outer faces.

  The hollow ribs have, in a horizontal section, walls against undercut, which may have the shape of a -, a trapezium, a parallelepiped or the like.

  The undercut facilitates the nesting of these ribs in the mass of concrete. These ribs against undercut prevent any displacement of the wall, carrier of these ribs, towards the inside of the gutter during lateral thrusts, creep, etc.. Excellent compression and buckling behavior is therefore obtained, particularly in the case where the concrete can not reach the surface.

  Preferably, the grids are made shorter than the channel element so that the longitudinal thrust causes their shift to fill these initial games when the end of an unsightly space. In the center of each grid are provided, preferably, pads The invention also relates to a drainage channel for pavements or access roads consisting of the assembly of channel elements according to the invention.

  The invention will now be described in more detail with reference to the drawing in which: FIG. 1 shows a side view of a gutter element according to the invention; FIG. 2 represents a front perspective view of the end of a channel element according to FIG. 1 provided with the male assembly member, FIG. 3 represents a front perspective view of the end of an element. gutter according to Figure 1 provided with a female connecting member; Figure 4 shows the sectional view along A-A of Figure 1, Figure 5 shows the sectional view along B-B of Figure 1; and FIG. 6 is a slightly perspective view of a side exit of the gutter element of FIG.

  A channel element 1 according to the invention is intended to form a drainage channel for roadways or access roads. This channel element 1 consists of a U-shaped section gutter body 2 whose 2861758 horizontal upper ends of the branches are arranged to receive a metal grid or plastic.

  The gutter body 2 has at its two ends assembly members of said gutter body with one or two other gutter bodies.

  One of said ends is provided with a male assembly member consisting of a rib 3 formed radially projecting at the end of the channel body 2.

  At the opposite end of the channel body 2, there is provided a complementary female coupling member of said male member and constituted by a groove 4 formed at the end of the channel body 2.

  This groove 4 is open towards the inside of said body 2 and receives vertically sliding the two channel elements, the rib 3 of the other channel element 1.

  Thus, the female assembly member and the male assembly member slide together in a vertical plane to assemble said channel elements 1.

  Preferably, the groove 4 has two complementary studs 5 of recesses 6 formed in correspondence in the rib 3, to ensure locking in position of the two channel elements 1. Of course, the studs could be arranged on the rib and the recesses in the groove.

  A channel element 1 according to the invention comprises at least one lateral outlet 7 for connecting said channel to others or to an evacuation tube. This lateral outlet 7 formed at the end of the channel element 1 as 3 (this is visible in Figure 1 or 6, has a lidding 8 having a thinning 8a of the circumference and a weakening 8b in the form of a cross 6 2861758 to direct a shock wave during uncapping. This lateral outlet 7 is provided with a male assembly member such as a rib 3.

  Preferably, the channel body 2 has hollow reinforcing ribs 5 on its outer faces.

  As shown in FIG. 4, the hollow ribs 9 have, in a horizontal section, undercut walls giving the shape of a Q and having an angle of 5 to 45 on both faces. This SZ shape thus constitutes a vertical hollow beam which, once surrounded by the concrete, prevents any inward movement.

  A channel element thus makes it possible to produce a drainage channel having greatly improved rigidity and stability.
