Definitions

  • the present invention relates to a channel element for a drainage channel for roadways consisting of a channel body of thermoplastic material with a U-shaped section, the horizontal upper ends of the branches of which are arranged to receive a metal rebate for receiving and maintenance of a metal grid fixed to the channel body by fixing means such as screw / nut.
  • the drainage channel is produced by assembling said channel elements.
  • Such channel elements which may have a length of 1 m, consist of parts such as a channel body, as well as metal rebates and a grid made of steel or cast iron, and of corresponding length.
  • a drainage channel When a drainage channel is placed on a roadway, it undergoes longitudinal and / or lateral forces exerted by the wheels of vehicles when cornering or during braking. In particular, the forces exerted can cause displacement and / or tearing of the grids and rebates relative to the channel bodies.
  • Such a channel element is described in particular in EP-A-0 748 903, where a channel is proposed with a locking grid locking system.
  • this element comprises a channel body essentially in a U shape, a covering grid arranged on an upper edge of the channel body as well as a cross member housed by its ends in the internal lateral walls of the channel body so that 'It is located inside the body of the gutter at the transverse of the longitudinal axis of the latter.
  • a bore is formed in the side walls of the channel to receive a pin which passes through an orifice in the grid to be engaged in the bore.
  • Document DE-A-298 08197 proposes a channel element of the type consisting of a U-shaped body whose side walls respectively carry in their upper part a metal rebate.
  • the side walls of the U-shaped body respectively have a longitudinal groove in which is housed a longitudinal rib formed on the metal rebate. It is thus proposed to immobilize the metal rebate even better on the channel body.
  • this groove has a rounded shape requiring a complementary shape of the branch of the rebate coming opposite.
  • a longitudinal sliding phenomenon of the grid can occur along the groove, which does not favor the locking of the grid but on the contrary disturbs it.
  • the metal rabbet comprises an outer wing provided with a projection suitable for being housed in a groove formed on the exterior face of a side wall of the body of gutter.
  • the rib is formed in V on the external face of a side wall of the U-shaped channel and the projection is also formed in V in a complementary manner to be housed in the groove.
  • the device is complicated because the wing of the rebate must have the complementary V-shape of the V-shaped groove and, moreover, the longitudinal sliding of the rebate along the groove is not prevented.
  • the manufacture and assembly of these different elements to form the channel element generates a high manufacturing cost but moreover, the disadvantages linked to the presence of the forces exerted by the vehicles are not surely avoided. and which can cause displacement and / or tearing of the grids and rebates with respect to the channel bodies.
  • the main object of the invention is to propose a channel element, the assembly and locking of the metal parts such as the rebate and the grid on the channel body give said channel element, high resistance to the longitudinal and lateral forces exerted by the vehicles on the roadway comprising such channel elements.
  • Another object tends to also propose a channel element whose manufacture, assembly and locking of the rebate and the grid are economically advantageous.
  • the subject of the invention is a channel element for a drainage channel for roadways, consisting of a channel body of thermoplastic material with a “U” shaped section, the horizontal upper ends of the branches of which are arranged to receive a metal rebate for receiving and holding a metal grid fixed to the channel body by fixing means such as screw / nut, the channel body having at least one bore formed at the horizontal upper ends of its branches so as to be opposite complementary orifices provided respectively in the rebate and in the grid to receive, preferably with clearance, a grid fixing screw, characterized in that the channel body further has a housing formed in said channel body under each bore to receive a nut which cooperates with a screw while below said housing is provided another bore e of diameter less than the diameter of the screw so as to create an anti-loosening thread lock during assembly on the body of the thermoplastic channel, as well as at each of its upper ends of branches on the internal vertical face of those -this, a V-groove inside the channel body, provided essentially in its median zone, with
  • the channel body has, as locking means, at least one bore formed at the horizontal upper ends of its branches so as to be opposite complementary orifices provided respectively in the rebate and in the grid to receive a grid fixing screw, as well as a housing formed in said channel body under each bore to receive a nut which cooperates with a screw and below said housing is provided another bore of smaller diameter to the diameter of the screw.
  • the fixing screw is then engaged through the orifice of the grid and then that of the rebate and then cooperates with the nut, the end of said screw being able to be engaged in said bore of smaller diameter, when the channel body is hot at the end of the press.
  • the channel body has at each of its upper ends of the branches, on the internal vertical face of these, a V-groove inside the body channel, provided essentially in its central region, with at least one projection such as a stop, a boss or the like.
  • the rabbet then has at least one cut in the middle part through which is engaged with play a projection of the V-groove of the channel body, hot at the press outlet of said channel body, the play between the cut and the projection allowing symmetrical withdrawal of the channel body on either side of said projection.
  • the central projection blocks in translation the rebate relative to the channel body, which generates good resistance to lateral and longitudinal forces, while allowing identical removal of the channel body on either side of the projection. during cooling and, no longer, a withdrawal at one end of the channel body randomly.
  • the mounting and locking of the metal parts that are the rebate and the grid on the hot channel body at the press outlet are made possible by the integration of post-shrinkage of the plastic material constituting the channel body over the entire length thereof relative to said rigid metal parts locked in said channel body.
  • a channel element according to the invention makes it possible to avoid longitudinal and lateral sliding of the grids during the passage of vehicles.
  • the channel element thus formed has a high resistance to lateral and longitudinal forces as well as a good locking and non-loosening in response to urban roads.
  • the subject of the invention is a method of assembling a drainage channel element for pavements consisting of a channel body with a “U” shaped section, the horizontal upper ends of branches of which are arranged to receive a metal rebate for receiving and holding a metal grid fixed to the channel body by fixing means such as screw / nut, characterized in that the channel body is formed by injection molding in thermoplastic material, each having its upper ends of branches, on the internal vertical face of these, a V-groove inside the channel body and provided essentially in its median part with at least one projection, then, hot at the press outlet , a metal rebate is provided on each horizontal upper end of the branches of the channel body provided with at least one cut in the middle part through which a s the channel body is engaged with clearance, then the grid is installed which is then fixed with screws which are engaged with clearance respectively in orifices formed in the grid and in the rebate and in bores provided correspondingly in the channel body then which cooperate with nuts housed in the channel body before being engaged in bores made in the channel body under
  • the method according to the invention allows locking of the metal elements of the channel element on the channel body ensuring good resistance to assembly to lateral and longitudinal forces exerted on a floor while allowing hot assembly at the press outlet, an economic condition for manufacturing with heavy and bulky parts.
  • Figure 1 shows a perspective view from above of a channel element according to the invention
  • FIG. 2 represents a partial view of the male end of a channel element according to the invention
  • Figure 3 shows a partial sectional view along line A-A of a channel element of Figure 2;
  • Figure 4 shows a partial sectional view along line B-B of Figure 3.
  • FIG. 5 represents an enlarged perspective view of a detail of FIG. 1.
  • a channel element 1 consists of a channel body 2 of thermoplastic material carrying at each of its horizontal upper ends of the branches 2a a metal rebate 3 intended to receive a metal grid 4.
  • Each upper end of a branch 2a of the channel body 2, on the internal vertical face of said branch 2a, has a V-shaped groove 5 open towards the inside of the channel body 2.
  • the rebate 3 has an “h” shape obtained, for example by folding a metal sheet, the small branch 3a of the “h” being short and folded inwards.
  • This rebate 3 is positioned on the horizontal upper end of a branch 2a of the channel body 2 so as to pinch said upper end, the small folded branch 3a of the rebate 3 being housed in the groove 5 in V as is visible in FIGS. 1 and 4 while the other branch 3b of the rebate 3 extends along the external face of the branch 2a of the channel body 2.
  • the channel body 2 has, in addition, at the horizontal upper ends of its branches 2a, bores 6 positioned so as to face opposite orifices 7, 8 formed respectively in the rebate 3 and the grid 4 to receive a screw fixing 9 of the grid 4.
  • a nut 10 is also provided in a housing formed in the channel body 2 in the extension of the bore 6 and which can cooperate with the screw 9 when the latter is engaged through the orifice 8 of the grid 4 then of the opening 7 of the rebate 3 then in the bore 6 of the channel body.
  • the orifices 7 and 8 receive the screw 9 with a clearance 12 (visible in FIGS. 3 and 4), which authorizes the withdrawal of the thermoplastic material during the cooling of the channel body 2.
  • the V-shaped groove 5 formed at the vertical upper ends of the branches 2a of the channel body 2 is provided in the middle part, with a projection such as a stop 13.
