Definitions
- the present invention relates to a concrete channel element reinforced with a bottom and two side walls rising to from and on either side of said bottom, each end upper of said side walls having a profile protective metal and / or housing for a grid cover, the reinforcement of reinforced concrete with elements of metal reinforcements fixed to said metal profiles.
- the invention also relates to a gutter made up of these channel elements.
- Document FR-A-2.634.234 describes a channel element as mentioned above where the metal frame, embedded in the channel element concrete consists of a plurality hoops distributed along the length of the gutter, and arranged each in a transverse plane of the latter, the ends of these arches being fixed to the metal reinforcements protecting the upper part of the two side walls.
- This element of channel together with a plurality of other elements identical, can be aligned longitudinally to form a gutter.
- the document FR-A-2,649,423 describes a channel element as mentioned above, where the aligned hoops are arranged in the transverse plane of the channel element and where the ends of each hoop are fixed respectively in two sleeves extending perpendicular to said reinforcements or metal profiles, the upper part of each sleeve being provided to receive a fixing screw of the plate wire rack.
- the object of the present invention is to provide an element of channel with improved load resistance.
- the channel according to the present invention is characterized in that that the reinforcement of reinforced concrete has a first type elements of metallic reinforcements which are fixed to said metal profiles via sockets provided to receive a grid fixing screw, and a second and third types of metal reinforcement elements welded to outer and inner parts respectively of metal profiles.
- the triple fixing of the metal profile on the frame interior of the channel element guarantees a seat and perfect support between the metal profile and the end concrete upper vertical walls so as to guarantee maximum maintenance of completeness between the plate grid and vertical walls.
- the first, second and third types of reinforcement elements metallic can be generally U-shaped hoops, which are embedded in the concrete of the gutter which has a corresponding U-section, the free ends of each hoop being fixed to the metal profiles.
- the grid fixing screw receiving sleeves are arranged below a horizontal part of the profiles metal that carries the grid and in that they are closed at their lower part by a solid lug welded against the first type of metal reinforcement elements.
- the metal profiles have flaps each having partially cut and folded parts intended to serve as support for making a mechanical connection by welding between the metal profiles and the second and third types of metal reinforcement elements.
- FIG. 1a there is a channel element 1 comprising a bottom 17 and two walls lateral and vertical 3 and 4 which extend on both sides and across from the bottom 17 up.
- These vertical walls 3 and 4 are each covered with a metal profile 9, 9 'whose faces main 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 at level of the highest parts 9a of the sections 9 and 9 '.
- the grid plate 2 has along these lateral edges a number of notches 14 which are provided with holes 15 allowing the passage of screws 13.
- the metal sections 9 and 9 ' have below from the surface 9c and at the holes 10, the sockets threaded inside, allowing to fix the plate grid 2 on the metal profiles 9 and 9 'by tightening the screws 13 in said sockets.
- the number of screws 13 and holes 10 in the longitudinal direction of the gutter will be determined so as to obtain the desired solidity of the channel.
- the grid plate 2 further comprises a plurality of slots 12 which extend essentially perpendicular to the longitudinal direction of said plate 2, slots which can have, as shown in Figures 1a and 1b, a shape curved 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 elements on its upper surface deflectors 16 which constitute slight projections and which may have extensions in the longitudinal direction of the grid plate 2 so that they cover essentially the entire width of the bars 19.
- the purpose of the curved shape of the slots 12 is the enlargement of the probability that water streaks crossing said plate grid - which will be found after the final installation of channel element 18, at ground level - falling into the slots 12 instead of passing through the grid plate 2 at level of bars 19.
- Channel element 1 has a front and rear surface essentially corresponding to cuts perpendicular to the longitudinal direction of the channel element, and these sections include profiled formations 6 and 11, so that constitute a fitting element during assembly longitudinal of several channel elements as illustrated in Figures 1a and 1b.
- the front and rear faces that have just been described have axial holes 7 and 7 'of an axial extension limited, holes which allow the insertion of studs 7a and 7a ' so as to obtain an exact alignment of the front surface 5 of an element with the back surface of another neighboring element after the insertion of the pins 7a and 7a 'in the four holes, two and two of which are aligned longitudinally each time.
- a gutter which is made up of a number channel elements as illustrated in Figures 1a and 1b comprises, after alignment, two reservations, which extend along the entire length of the gutter.
- Figure 1b shows a channel element 18 identical to that of Figure 1a but in closed state, that is to say, the plate grid 2 was fixed on the upper ends of the walls 3 and 4 which are covered with metal sections 9 and 9 ', in 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 on its upper surface no protrusion which essentially exceeds the level of the upper surface of the grid plate 2 or the shoulders upper sections of metal profiles 9 and 9 '.
- Deflectors 16, them slightly exceed this surface as described above, this being however a desired effect for the reasons mentioned above.
- Figure 2 shows a step of assembling several channel elements 1a to 1e longitudinally one behind the other, in order to form a gutter.
- the set of channel elements has aligned longitudinal reservations starting from openings 8 and 8 'of the first channel element 1a, the alignment of these reservations being obtained by the parties profiles of the front and rear faces of the gutter as well as by studs 7a and 7a '.
- Each channel element 1a to 1e has a clamping means truck door lock type having 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 clamp the two channel elements together 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 maintaining the alignment of the set of elements channel in situations where the required force of mutual solicitation between the channel elements is not very high.
- employment locks 20a, 20b etc. can be considered alone and without support additional metal rods 21 and 21 'where the force of solicitation by said locks is sufficient for the type of channel that you want to make.
- Figure 3 shows a perspective of the metal profile which rests on the upper end of the vertical walls and side of the channel element 1, and this metal profile 9 has two horizontal surfaces, an upper surface 36 and a lower surface 37 which are separated by a shoulder 38, the surface 37 and the shoulder 38 being intended to come into contact with the side edges of the grid plate 2 as illustrated for example in figure 4.
- Flaps 30 and 31 extend downward from the opposite ends of the horizontal parts 36 and 37 in order to protect the upper extremities of surfaces interior and exterior vertical walls as is clearly visible in Figure 4.
- the horizontal part 37 has a plurality of sockets 34 of which only one is shown in FIG. 3.
- the socket 34 which extends downwards from a hole 10 ( Figure 1a) is threaded inside and closed at its lower part by a solid lug 35 which will serve as a support welding to secure the socket 34 (together with the screws 13 - figure 1 - which it will receive) with an element of metallic reinforcement 42 (FIG. 4).
- a plurality of sockets 34 is arranged below the holes 10 to serve receptacle for the screws 13 which are distributed over the length of the grid plate 2.
- the flaps 30 and 31 also have distributed over the extension longitudinal section 9, a number of parts 32 and 33 partially cut and folded towards the inside of the profile 9, parts 32 and 33 which will be used as indicated in the left part of Figure 4, support for performing a mechanical connection by welding between profile 9 and bars of reinforcement 40 and 41 which pass through the channel element 1 in the form of bar in a similar way to the bar 42 which is welded on lug 35.
- Figure 4 the right part of which shows a cross section at the level of the screws 13, while the left-hand part shows a cut at the cut parts 32 and 33 of the flaps 30, 31 profile 9, clearly indicates that the channel element has a metal surround consisting of the bar 42, lug 35, sockets 34, screws 13 and plate 2 at the same that we find the screws 13 in the plates grid, while it includes a second and third partial encirclement formed by bars 40 and 41 which are found welded to outer and inner parts respectively of the metal profile.
- Element 32a is located completely inside the flaps 30 and 31 and has no intersection with the free edge 32b of this flap.
- the welding of the metal profile 9 on the bars 40 and 41 is independent of the placement in the longitudinal direction of the screws 13, and the number of bars 40, 41 which are distributed over a certain length of the channel element is independent of the number of encirclements according to the position of the screws 13.
- This triple fixing of the metal profile 9, 9 'to the frame interior of channel element 1 guarantees a seat and perfect support between the metal profile and the end concrete top of vertical walls 3 and 4 so that guarantee as much as possible the integrity between the plate grid 2 and the vertical walls 3 and 4.
- Figure 5a shows an example of execution of the lock located between two neighboring gutter elements as has already been mentioned during the description of figure 2, this lock comprising on the end side a first element of channel 1b, a hook 50 and, fixed on the opposite end of a neighboring channel element a loop 52 which is fixed in pivoting on this neighboring channel element 1a by means of two rings 54.
- the loop 52 can be pivoted around its part which is held by the rings 54, and the two branches longitudinal of the loop 52 have holes 53 allowing the passage of a second loop 51 which engages on the other hand in the hooks 50.
- FIG. 5b shows another embodiment of the means of Tightening.
- Two angles 77 are fixed in opposite directions on the lateral ends of two channel elements 1a and 1b so to be able to cooperate by screwing a bolt 57 which will pass through the holes 59 made in the two perpendicular parts 56 of angles.
- the parts 55 are preferably welded to elements of internal reinforcement of channel elements 1a and 1b by through the parts that penetrate the concrete.
- the clamping means according to FIGS. 5a and 5b can be used to maintain the elements of gutter in their mutual position, but also and above all, they can be used to get a perfect match of two elements after their rough installation.
- Figure 6 shows the interface between two opposing ends of the two adjacent channel elements 1a and 1b which are held in their relative position by a closed lock as described in more detail with reference to Figure 5, after the have aligned before by the nesting of their parts profiles 6 and 11.
- the grid plates 2a and 2b have been designated without details of their slot structures and bars, the longitudinal side edges of these plates represent on the lower horizontal parts of metal profiles 9a, 9b and 9a ', 9b'.
- Metal rods (cables) 21, 21 ' have been passed through through longitudinal reservations described in more detail with reference to the previous figures, and nuts 60, 60 ', 60a are designated before their engagement on the rods 21, 21 '.
- the channel elements 1a and 1b have on their surface interior a waterproof coating 61 which covers all of the interior surfaces of the bottom and vertical walls of said channel element, this waterproof coating 61 further extending, on each side 62, between the upper part of the vertical wall and between the metal profile 9a, 9a 'so as to come out at 63 outward below the side flaps 31 as illustrated in figure 3.
- the coating 61 adheres perfectly against the surfaces interior of the concrete parts 64 which constitute the bottom and the vertical walls of the channel element and makes this element of waterproof channel.
- Such an arrangement of a waterproof coating and optionally corrosion resistant can be provided for applications special of a channel which should conduct liquids which could have a detrimental effect on concrete.
- Such welding is obviously done before closing the channel by the set of grid plates 2a, 2b, etc., welding which may be preceded by the deposition of a metal wire in the slot which is created between the two coverings 61 of the elements of neighboring gutter, metal wire that can be used later for the verification of the quality of the welding in looking for an electrical breakdown between this wire and a probe control that is passed manually along said weld.
- the parts 63 of the waterproof coating leaving laterally vertical walls of channel element 1a or 1b can be used to make a waterproof connection with another coating waterproof or a waterproof layer that will be or has been deposited previously on or in the neighboring soil in order to obtain a complete sealing of the soil surface in a certain place.
- An axial stress between the various channel elements is particularly advantageous for elements bearing sealed layers sealed between the elements, to ensure their relative immobility.
- FIG. 6 shows several stages of the formation of the waterproof coating 61 of FIG. 6, and one understands that this coating 61 is constituted by a structure semi-rigid of a polymer or other material found on the market in sheet or plate form.
- Figure 7a shows the two parts 70 and 71 of a mold pressing between which the original sheet 72 is placed, mold which has a positive and a negative of the form interior of a channel element and the form 73, 74 of the metal profile mentioned above.
- the mold part 71 has a shoulder 76 and the part 70 of the mold a shoulder 75 serving as a set of scissors for cut the edges of sheet 72 when fully closed of the mold, as illustrated in FIG. 7b where the strands are distinguished side 72a constituting the cut side edges of the sheet 72 '.
- the two parts of the mold 71 and 70 are heated by means of integrated heaters not shown, as is known in the art of thermoforming.
- Such a channel element can be carried out by first depositing the metal sections 9a, 9a 'at the bottom of a concrete casting mold, after which the sheet 72 'of Figure 7c is placed in the mold so as to engage its corresponding parts in the profiles metallic.
- the surfaces interior of these metal profiles have parts 32, 33, 34 and 35 which must pass through the waterproof sheet 72 ' in order to be connected by welding to a metal frame which will also be placed in the mold, and after drilling these parts 32 to 35 through the waterproof sheet 72 ', the different welding steps that have been described in connection with Figure 4 above are performed and the mold is then filled with concrete.
- Demolding produces a channel 1 element as was illustrated in FIG. 1a, channel element which will be closed by a grid plate 2 at the desired time.
- the metal profiles 9 can be made of steel, possibly galvanized and the grid plates 2 are advantageously made of cast iron.
- a coating of metal profiles 9 as well as grid plate 2 in PVDF or other could be considered in order to give the channel an upward exposed surface which is smoother and whose microstructure allows cleaning possibly easy by applying a simple jet of water.
- PVDF or other coating may be provided in one color whatever will be related to the interior of the building in which we made the gutter.
- a length of galvanized steel profile according to Figure 3 is first treated with acid to obtain a stain removal. Then the profile is rinsed twice with tap water and a third times, with demineralized water, and dried and degassed at 200-210 ° C.
- An anti-corrosion treatment will follow the drying and then the profile is passed through a powder application booth polymerizable or capable of forming a waterproof coating profile temperature, which will be for example for a polyester powder between 210 and 220 ° C.
- a new treatment of drying / degassing at 200-210 ° C will end the process.
