Definitions

  • the invention relates to the production of vaulted structures such as passages lower, or upper, roads and highways and other constructions analogues.
  • the SAMFLO document FR 2 751 675 teaches a method of making a vault in which two half-shells are placed, provided with a spoiler and support fittings, on shooting soles made on square. The two half-shells are then supported one on the other, by through the fittings, and a continuity keying between the upper edges of the two half-shells, on the spoilers, in order to make a keystone ensuring a transverse connection of continuity of the half-shells.
  • fittings which ensure the support of the half-shells one on the other before key, are embedded in concrete and therefore lost. Now, these fittings represent a few percent of the cost of building a vault. The The plaintiff therefore sought to reduce the cost induced by these fittings.
  • the invention relates to a method of producing a vault in which is supported by at least two half-shells one on the other by at least two supporting pieces that we match and, each half-shell comprising an upper edge and a bottom spoiler, we sink a keying material between said upper edges, on the bottom formed spoilers, to ensure a transverse connection of continuity of half-shells, process characterized by the fact that each part is fixed of support on a half-shell in a removable way, one puts in provisional support the two half-shells by their support piece without supporting their bottom spoilers, and, after pouring the keying material to proceed with a transfer of forces from the support pieces to the half-shells, the supporting parts.
  • the support fittings can be reused later for the realization of a new vault.
  • FR 2 723 116 PREFAC
  • PREFAC PREFAC
  • a process for producing a vault using at least two half-shells each comprising a bottom spoiler, in which the two half-shells are supported, spoiler against spoiler, with interposition of a compressible stud, and, for avoid any relative escape of the two half-shells and thus secure the support, we connect the two spoilers using a metal plate that we fixed to the undersides of the spoilers.
  • the plate is put in place after stud and, therefore, after the compression thereof and the support half shells. As a result, it does not participate in the support half shells.
  • the stud and the plate are normally removable. However, the stud being compressed between the two half-shells, it turns out cannot be removed later. However, if the stud is inserted between the spoilers, these are the ones that support the support effort of the two half-shells one on top of the other, even after the concrete has been poured, and not not the keying sill. It follows that the vault thus produced is exposed to premature wear.
  • the support pieces can be placed at least partially above the half-shells or at least partly below the half-shells.
  • it is placed end to end in two rows longitudinal two pluralities of half-shells and each half-shell of one of the rows on a half-shell of the other row, by means of at least two support pieces, respectively male and female, that we match so that the supporting parts of one of the two genera support the supporting parts of the other kind.
  • the support points of the half-shells on each other are all at the same level, which ensures greater stability of the arch and a perfectly continuous underside.
  • the invention also relates to a support piece for supporting the half-shells of the vault produced according to the above process, comprising a transverse support arm, characterized in that it comprises removable fixing means substantially orthogonal to the transverse arm.
  • the invention also relates to a half-shell for the realization of the vault according to the above process, characterized in that it comprises support piece receiving means.
  • the vault shown in Figure 1 is intended for the realization of a underpass under embankment and includes two longitudinal rows 10, 11 of prefabricated half-shells 1-8, here in concrete, arranged end to end, on either side of a median vertical longitudinal plane P, and secured transversely by a keystone 9.
  • the vault includes four end half-shells 1, 2, 7, 8 (two to each end) and here four intermediate half-shells 3-6, located between the end half-shells 1, 2, 7, 8.
  • the two half-shells end 1 and 8 have a width 1 equal to half the width L of the other half-shells 2-7.
  • the half-shells 3, 5 and 7 of row 10 are offset by half a width 1 of half-shell, in the longitudinal direction, by compared to the half-shells 2, 4 and 6 of the other row 11.
  • the half-shells 1-8 of the vault are thus staggered. Note that the width of a half-shell means the dimension of this half-shell in the longitudinal direction of the vault.
  • each half-shell of one longitudinal rows 10 (11) is supported on a half-shell from the other longitudinal row 11 (10) via two pieces support, or "support fittings", temporary 30, 50, respectively male and female, that we match.
  • Figure 3 shows two support pieces paired 30, 50 by means of which the half-shell 2 is in support on the half-shell 1.
  • the half-shells 2-7 of length L are all identical. For the sake of clarity, only the half-shell 2 will now be described.
  • the half-shell 2 constituting a portion of the wall of the vault, comprises a lower support edge 20 and a substantially vertical upper edge 21 at functional position.
  • the half-shell 2 further comprises two external shoes, or sheaths 23 for receiving a support piece, fixed to the upper edge 21 of the half-shell and arranged substantially at a quarter and three-quarters of the width of the half-shell respectively.
  • Each shoe 23 consists of a tube, or sheath, of square section, having an upper opening 24 of passage of a foot for fixing the support piece, the opening 24 extending in the plane of the upper face of the half-shell 2.
  • the shoe 23 is pressed against the upper edge 21, by one of its lateral faces, and fixed to the half-shell 2 using a threaded anchor rod 26 and a nut 25 screwed on the rod 26.
  • the half-shells 1 and 8, of length 1 are similar to the half-shell 2 described above, except that they do not contain a single external shoe for receiving a workpiece fixing foot support, arranged substantially at half the width of the half-shell.
  • the female support pieces 30 include a transverse support arm 31 and a removable fixing foot 32.
  • transversal is meant to qualify what extends orthogonally to a vertical plane extending in the longitudinal direction of the arch.
  • the transverse support arm 31 comprises an external tube 34 of section square, open at one of its ends by an opening 35, and a tube internal 36 slidably mounted in the external tube 34 and provided, at one of its ends of a female support head 33 protruding from the outer tube 34 through the opening 35.
  • the support head 33 is concave and provides a cavity receiving a convex male support head 53.
  • the inner tube 36 and the outer tube 34 are connected to each other by a rod transverse thread 37 fixed to the bottom wall of the inner tube 36 opposite to the support head 33, by a fixing system 39, and extending through the bottom wall of the outer tube 34, opposite the opening 35.
  • a nut 38 is mounted on the portion of the threaded rod 37 protruding from the outer tube 34 and welded to the bottom wall of the outer tube 34.
  • the support arm 31, telescopic is thus adjustable in length, by screwing and unscrewing the rod 37.
  • the removable fixing foot 32 integral with the transverse support arm 31, is orthogonal to it and supported by stiffeners 40, 41.
  • the foot of attachment 32 intended to be removably fitted into an external shoe receiving half-shell, has a square section, of dimensions substantially equal to those of the inner section of the hoof.
  • the male support pieces 50 differ from the female support pieces 30 only by the fact that they include, instead of the female support head 33, a male support head 53 of convex shape.
  • the respectively concave and convex shapes of the support head 33 of a female support piece 30 and the support head 53 of a male support piece 50 are such that they provide vertical and horizontal support for one of the support pieces 30 (50) by the other support piece 50 (30), after pairing of the two parts 30, 50 by introduction of the male support head 53 into the female support head 33.
  • Male 50 and female 30 support pieces are removably attached to the half-shells 1-8.
  • a single support piece here male, is removably fixed.
  • the length of the support arms of the male support pieces 50 is adjusted and females 30 so that the contact surface of the supporting parts matched of each pair of pairing extends substantially in the plane longitudinal median P of the arch.
  • the two support soles 12, 13 are made by sparing in each of them a groove for receiving the lower support edges of the half-shells 1-8.
  • the half-shell On one of the shooting soles 12, the half-shell is put in place end 2 which is stabilized. One then sets up one 1 of the half-shells end of length 1 on the strip base 13 and it is put in support on the half-shell 2, via the male support piece 50 of the half-shell 1 and of one of the female support pieces 30 of the half-shell 2 that we match.
  • the male support piece 50 When pairing a male support piece 50 and a support piece female 30, the male support piece 50 is supported on the support piece female 30 so that the female support part 30 supports the part male support 50. Thus, all the female support pieces 30 of the arch support the male support pieces 50.
  • the last half-shell put in place is the end half-shell 8, of length 1, which is supported on the end half-shell 7.
  • the parts After pouring and drying the keying, the parts are separated from each other male 30 and female 50 support for each pair of paired support pieces, by unscrewing the rod 37 from one of the support arms of the pair of pair 31. There is thus a transfer of forces from the support pieces 30, 50 to the half-shells 1-8.
  • the effort transverse support of each pair of half-shells, supported one on the other is supported by the keystone 9.
  • each of the support pieces 30 (50) is removed, taking its foot out fixing 32 of the shoe in which it is fitted by vertical displacement towards the top.
  • the supporting parts for that the female support pieces support the male support pieces.
  • the half-shells 60 include, in place of the external shoes 23, internal shoes 63 embedded in the thickness of the half-shell 60, below the upper edge 61 thereof.
  • Each shoe 63 consists of a sheath of square section and longitudinal axis 64. This axis 64 is here slightly inclined relative to the vertical, the distance between the axis 64 and the upper edge 61 of the half-shell 60 decreasing upwards.
  • the support pieces 70 male and female, include a support arm transverse 71 and a fixing foot 72 intended to be fitted into a shoe internal 63.
  • the support arm 71 similar to that previously described, extends along an axis 73.
  • the fixing foot 72 has a square section equal to the internal section shoe 63, and extends along an axis 74, substantially orthogonally to the transverse arm 71.
  • the angle formed between the axis 73 and the axis 74 and located on the side of the support head of the support arm 71, is slightly greater than 90 °.
  • each half-shell in place of the hooves, includes at least one hole made in its upper face, below the edge upper, in which an internally threaded sleeve is installed.
  • the socket does not pass through the thickness of the half-shell.
  • Support pieces temporary include a transverse support arm and, in place of the foot fixing, a passage for receiving a fixing bolt, of orthogonal axis to the transverse support arm.
  • the supporting pieces are placed at least in part above the half-shells. We could just as easily arrange the supporting parts at least partially below the half-shells.
