Definitions

  • the invention relates to a look element, in particular made of concrete, having a peripheral wall having at least one opening for connecting a pipe, said opening being encircled, internally, by a closed seal by an operculum and secured by molding the element of look.
  • the invention further relates to a seal for the manufacture of a look element.
  • the present invention will find its application in the field the construction of pipeline networks for the flow liquid or cable networks.
  • look elements generally buried in the ground and closed by a closing slab appropriate, allow to connect several conduits and, where appropriate, to carry out checks.
  • Such eye elements are in the form of concrete or other molded material and take a form simple geometric, preferentially parallelepipedic. At level of their peripheral wall they include either a plurality of cassia prints, or pre-equipped openings a closed seal of a seal. According to number of pipes to be connected at a glance, the operator must either perforate the latter to the right of breakage loans corresponding, either to release from their operculum the joints sealing of the openings concerned. Note that in the case of fingerprints, he must bring back this seal sealing after making the openings, in all before inserting the pipes to be connected to the element of look.
  • the directory seal To return to the directory seal, it includes a body of cylindrical general shape provided on its periphery outer ring beads intended to promote its anchoring in cast concrete. Internally, it has two annular lips spaced axially from each other. These adopt a triangular section and are tapered to their free end.
  • the operculum As for the operculum, it is in the form of a disc of diameter adjusted to the internal section of the joint. It can to be introduced into it, from the outside of the eye, until abutting on the first annular lip.
  • This operculum further comprises a cylindrical skirt extending concentrically on the back of the above-mentioned disk. this skirt is of section substantially lower than this disk, while being greater than the opening delimited by a lip annular. Also, it must be engaged in force through this first lip of the joint.
  • the closed maintenance of a seal on a seal does not not receiving a connecting pipe, is provided by the ground embankment surrounding this look at the end of the pose.
  • the operculum may present a free play in case absence of backfill or insufficiently compacted soil around a glance and under the effect of an increase in pressure in the eye, this operculum can be ejected from its seal. It is impossible to put it back in place without that it is necessary to dig around this look.
  • the present invention proposes to provide a solution to all the aforementioned problems.
  • the invention relates to a look element, particularly in concrete, having a peripheral wall having at least one opening for connecting a pipe, said opening being encircled, internally, by a seal annular made integral by molding the eye element and having a cylindrical body closed by a lid, characterized by at least one end leading to inside the eye element, said cylindrical body presents a shoulder conferring, locally, a section larger internal relative to which is adjusted the cover comprising anchoring means provided for cooperating with complementary fastening means designed along the shoulder.
  • the shoulder defines a recess at level of the internal section of the corresponding cylindrical body to the seal, this shoulder forming an abutment plane for the operculum introduced from the inner side to the element of look.
  • said seal at its end opening out of the eye element, has a frustoconical mouth defining a section decreasing from the outside of said element of look inward.
  • the cylindrical body of said seal comprises, internally, a ring lip extending at a given angle of inclination since the outside of the eye element inwards.
  • the invention further relates to a seal with operculum for the manufacture of a look element
  • the lid can be removed at the last moment, even under the impulse of the pipe that we just insert in the corresponding seal.
  • the mouth of the seal, the outer side to the element look, frustoconical shape, it abuts a lip that is, itself, inclined in the direction of introduction of the pipe. If assembly is facilitated, the operator can also very easily evacuate any dirt that may be accumulated at this joint before the engagement of the pipe.
  • the frustoconical shape of the mouth of the joint allows a certain angular displacement of the connected pipe on the look element.
  • the present invention relates to a viewing element 1, especially for cable network or buried sewerage.
  • This element of look 1 presents, here, a form parallelepiped, in particular square and has a wall device 2 provided with openings 3 for the connection of pipes.
  • Such a look element 1 generally of concrete is usually designed by molding.
  • joints sealing rings 4 in which are placed closure caps 5.
  • This seal 5 makes it possible, in particular, to confer on the seal 4, made of flexible material, the mechanical strength necessary to resist the molding and vibration compacting of concrete.
  • the seal 4 comes to circle, internally, the opening 3. It comprises a cylindrical body 6 of length equal to the thickness 7 of the peripheral wall 2 of the element of 1. Externally, this cylindrical body 6 comprises, advantageously, means 8 intended to ensure its anchorage in concrete during molding. These means are presented by for example, in the form of a peripheral rib 8.
  • this body 6 of the seal 4 can be provided with fastening means, such as a tongue attachment 10, facilitating its handling and storage, knowing that it can still be used to position the seal sealing 4 in the mold for the design of the element look.
  • this cylindrical body 6 of the body 4 has a shoulder 12 conferring, locally, a larger internal section compared to which is the operculum 5.
  • anchoring means 13 defined capable of cooperating with anchoring means complementary 14 to equip the seal 4, the along the shoulder 12.
  • the operculum 5 is in the form of a extended disk, at the edge 16, of a cylindrical skirt 17 having, externally, at least one peripheral rib 18, section redan, constituting said means anchor 13.
  • complementary anchoring means 14 they are defined by at least one boss or a peripheral rib 19 arranged at the inner wall of the cylindrical body 6 of the gasket 4, along the shoulder 12.
  • peripheral rib 18 forms a inclined plane, on its side 20 oriented towards the direction introducing the cap 5 into the seal 4, it passes without difficulty and under the effect of a force of measured pressure the rib 19 corresponding to the means complementary anchors 14 in the joint 4.
  • the opposite side 21 of the rib 18 being configured in the form of redan, it comes into abutment against the peripheral rib 19 the along the shoulder 12 when attempting to extract the operculum 5 of the seal 4.
  • the removal of the operculum 5 can not intervene than voluntarily and under the effect of sufficient pressure exerted inward of the gaze element 1 through the corresponding opening 3.
  • the shoulder 12 defines a recess 22 forming a stop plane against which is positioned the free end 23 of the cylindrical skirt 17 which borders the disc 15 of the lid 5, during the engagement of the latter in said seal 4.
  • the distance 24 between this setback 22 and the end 11, internal to the eye element 1, the body cylindrical 6, is at least equal to the thickness 25 of the operculum 5 so that it does not overflow on the internal side of this eye element 1, during molding.
  • cylindrical body 6 has a mouth 26 of frustoconical shape, at its end 27 oriented towards the outside of the viewing element 1.
  • this frustoconical mouthpiece 26 facilitates the connection on a pipe, it still allows some angular mobility of the latter compared to the element of look 1.
  • the recess 22 extends at least one lip ring 28.
  • this is oriented with a certain inclination angle 29, from the outside towards inside the eye element 1, which favors, there again, the connection of a pipe.
  • the radial length 30 of this lip ring 28 is chosen to allow connection to the pipe look element of different sections.
