Definitions

  • the present invention relates to a reinforced concrete channel consisting of channel elements placed longitudinally one after the other, each channel element comprising a channel element of reinforced concrete and, optionally, a metal grid in particular. cast.
  • the invention also relates to a reinforced concrete channel element intended for manufacturing such a channel.
  • French patent application 89 09456 describes a channel element as mentioned above, an element which, together with a plurality of other identical elements, can be aligned longitudinally to form a channel.
  • the type of channel element described in this patent application has the advantage of being able to be used without requiring the pouring of a concrete bed on the place where one wishes to install a channel, because the clean reinforcement of this channel is such that it produces the stability required for this type of installation by itself.
  • a channel according to the invention is characterized in that the set of channel elements comprises a means making it possible to urge each channel element longitudinally against its neighboring channel element (s).
  • each channel element has through-hole longitudinal reservations making it possible to thread a rod or a wire rope axially through all the aligned reservations of the set of channel elements.
  • This metal rod (cable) can be threaded- (e) so as to allow two nuts to be screwed onto it (it) in the opposite direction from its two ends after having been threaded through all the longitudinal reservations of the assembly d 'channel elements, to compress or stress these channel elements against each other when tightening the nuts.
  • a fixed blocking on one end of the cable or of the rod and of a single nut on the other end.
  • each channel element can comprise a clamping means cooperating with the clamping means of a neighboring channel element, this type of biasing means being able to be present alone or in combination with the metal rods.
  • this clamping means can be a latch of the truck door type, and according to another embodiment, the clamping means takes the form of an angle which cooperates with another angle iron, arranged laterally on the front and rear faces of a channel element.
  • this clamping means may consist of two rings, each of which is disposed near the longitudinal end of a channel element so as to allow two elements to be clamped neighbors against each other by means of a removable clamping tool.
  • This embodiment is particularly advantageous since the tightening tool can be used only to maintain a pre-tightening during the application of the metal rods, and then the tightening tools can be recovered and only the two rings which are partially immersed in the reinforced concrete will remain on site.
  • a channel as described above consists of a plurality of reinforced concrete channel elements, which are aligned and optionally covered by a metal or plastic grid, and according to the invention these channel elements are characterized in that 'They each have at least two longitudinal reservations crossing the reinforced concrete part over its entire length.
  • the grid has slots which are essentially perpendicular to the longitudinal dimension of the channel element and these slots can be curved so that the curve lies in the plane of the grid.
  • the grid comprises a bar which has on its upper surface at least one deflector element which promotes the flow of a liquid passing through the grid in said slots.
  • a channel element according to the invention may comprise a channel element having two vertical walls and a horizontal bottom, each of the vertical walls being covered at its upper end with a metal profile intended to receive the two lateral edges of the grid.
  • This grid can be fixed to the channel element by several screws which enter the vertical walls of said channel element through the metal profiles.
  • Each metal profile can comprise several threaded bushings which are arranged below a part of the profile which carries the edge of the grid and at a corresponding level with holes in the grid which are intended for the passage of the screws.
  • each socket is extended downwards by a lug intended to be welded to a reinforcing iron of the channel element.
  • the metal profiles may comprise parts partially cut and folded towards the inside of the profile, said parts serving as attachment points by welding between the profiles and the reinforcing elements of the channel element.
  • each channel element has on its front face, a profiled projection which corresponds to a recess in the rear face so as to allow the interlocking between the front and rear faces of the two elements neighboring canal.
  • the front and rear faces of the channel elements comprise at least two axial holes which are intended to receive studs used for perfect alignment of the channel elements by insertion of said studs at the same time in each of the holes aligned two by two on the front and rear faces of the two neighboring channel elements.
  • the interior faces of the vertical walls and of the bottom of the channel element are covered with a waterproof polymer sheet.
  • This waterproof sheet can also be resistant to corrosion.
  • this sheet extends beyond the interior faces of the vertical walls and extends along the entire interface between the upper end of the vertical wall of reinforced concrete and between the metal profile.
  • a lateral edge of the waterproof sheet can come out at the interface between the concrete and the metal profile to allow this lateral edge to be connected with another waterproof sheet arranged laterally relative to the gutter.
  • This waterproof sheet can be preformed by thermoforming before being put in place to adhere to the interior of the channel element, such a preformation of the waterproof sheet can considerably facilitate the production of a channel element.
  • the metal profiles are advantageously made of galvanized steel, optionally coated with a polymer of the PVDF type with a tinted varnish, or with any other metallic or synthetic material.
  • FIG. 1a there is a channel element 1 having a bottom 17 and two side and vertical walls 3 and 4 which extend on either side of the bottom 17 upwards.
  • These vertical walls 3 and 4 are each covered with a metallic profit 9, 9 ′ whose main faces form a shoulder which is intended to receive the longitudinal edges of a grid plate 2 so that the upper surface of said grid plate 2 is located at the highest parts 9a of the sections 9 and 9 '.
  • the grid plate 2 comprises along these lateral edges a number of notches 14 which are provided with holes 15 allowing the passage of the screws 13.
  • the grid plate 2 further comprises a plurality of essential slots 12 which extend ment perpendicular to the longitudinal direction of said plate 2, slots which may have, as shown in Figures 1a and 1b, a curved shape so that the curvature remains in the plane of the upper surface of the plate 2 .
  • Each group of two slots 12 is separated by a bar 19 and this bar can carry on its upper surface deflector elements 16 which constitute slight projections and which can have extensions in the longitudinal direction of the grid plate 2 so that that they cover essentially the entire width of the bars 19.
  • the purpose of the curved shape of the slots 12 is to increase the probability that the water wires which pass through the said grid plate - which will be, after the final installation of the channel element 18, at the level of the floor - falling into the slots 12 instead of crossing the grid plate 2 at the bars 19.
  • said bars 19 include the projections 16 to direct a water stream which would engage to pass the plate on the back of said bars 19 to be deflected left or right to surely fall into one of the slots 12.
  • the channel element 1 has a front and rear surface essentially corresponding to sections perpendicular to the longitudinal direction of the channel element, and these sections include profiled formations 6 and 11, so as to constitute an interlocking element during the longitudinal assembly of several channel elements as illustrated in Figures 1 a and 1 b.
  • the front and rear faces which have just been described have axial holes 7 and 7 'of limited axial extension, holes which allow the insertion of the studs 7a and 7a' so as to obtain an exact alignment of the front surface 5 of an element with the rear surface of another neighboring element after the insertion of the pins 7a and 7a 'in the four holes, two and two of which are each aligned longitudinally.
  • openings 8 and 8 ' which delimit longitudinal reservations which pass entirely through the channel elements in the longitudinal direction and it is easily understood that a channel which is constituted by a number of elements channel as illustrated in Figures 1 a and 1 b comprises, after alignment, two reservations, which extend over the entire length of the channel.
  • Figure 1b shows a channel element 18 identical to that of Figure 1a but in the closed state, that is to say, the grid plate 2 has been fixed on the upper ends of the walls 3 and 4 which are covered with metal profiles 9 and 9 ', by tightening the screws 13 as mentioned above.
  • the heads of the screws 13 are then located in the notches 14 so that the channel element has no protrusion on its upper surface which essentially exceeds the level of the upper surface of the grid plate 2 or the upper shoulders of the metal profiles 9 and 9 '.
  • the deflectors 16, them slightly exceed this surface as described above, this however being a desired effect for the reasons mentioned above.
  • Figure 2 shows a step of assembling several channel elements 1 a to 1 e longitudinally one behind the other, in order to form a channel.
  • the set of channel elements has aligned longitudinal reservations starting from the openings 8 and 8 ′ of the first channel element 1a, the alignment of these reservations being obtained by the profiled parts of the front and rear faces of the channel elements as well as by the studs 7a and 7a '.
  • Each channel element 1 a to 1 comprises a clamping means of the truck door latch type comprising near the end of an element a stop or hook means 20c ', and on the other end of the channel element, a closing loop 20d so as to tighten the two channel elements one against the other after engagement of the loop 20c in the hook 20c 'followed by the pivoting of the loop 20c in the opposite direction to the hook 20c '.
  • clamping means can be used as the only means for permanently maintaining the alignment of the set of channel elements in situations where the required force of mutual stress between the channel elements is not very high.
  • nuts 60, 60 ′ are passed over the two strands of rods 21 and 21 ′ emerging from the front face of the first channel element as well as identical nuts 60 a over the strands of the rods 21, 21 'which come out of the rear surface of the last channel element and a longitudinal stress force is applied by tightening the nuts 60, 60a in the opposite direction against the front and rear surfaces of the first and last channel element respectively.
  • biasing means only the rods 21 and 21 'with their nuts 60 without applying the latches 20a, 20b etc. which allow only to maintain a pre-alignment to facilitate the introduction of the rods 21 and 21 'in the longitudinal bores, locks which do not however constitute an essential element in an embodiment where clamping by the rods 21 and 21 '.
  • locks 20a, 20b etc. can be envisaged alone and without the additional support of the metal rods 21 and 21 ′ where the stressing force by said latches is sufficient for the type of channel which it is desired to manufacture.
