Definitions

  • the present invention relates to profiled metal sheet piles, used in the building industry and public works, for the realization of foundation, retaining or protective works, works whose role is to separate two environments, generally a liquid environment of a solid medium and sometimes a gaseous medium of a liquid medium or of a solid medium.
  • sheet piles for construction: curtains for the defense of the banks of canals and rivers; flood protection screens along roads and highways in flood-prone areas; quay walls in ports and along rivers; perimeter walls of swimming pools; silos; containment walls of basins for the storage of gases, in particular of hydrocarbons; trench armor, during excavations; terrestrial retaining curtains; protections along the roads to prevent falling rocks.
  • a suitable product such as a cement or a resin, is injected into the empty space which may remain between the two complementary means engaged by each latch formed by the juxtaposition of two neighboring sheet piles.
  • the present invention relates more precisely to the field of profiled metal sheet piles with complementary open side loops.
  • loop sheet piles form longitudinal locks with excellent tightness, due to the particular geometry of the loops whose complementary hook-shaped profiles, male and female respectively, fit one into the other. other with, consequently, a large overlap.
  • the thickness of the sheet which must be worked in successive operations on a profiling machine, to gradually take the particular shape of the sheet pile, is limited by the profiling material to a value of the order of 12 mm.
  • the width of the sheet introduced into the profiling machine is also limited, to a value of the order of 1250 mm, a limit which is imposed by the profiling material itself; and insofar as the width of the original sheet is limited, it is understood that the development of the profiled sheet pile is also, both in height and in width.
  • the height of the finished profiled sheet pile is also limited, to a value of the order of 250 mm, on the grounds that the two loops formed along each longitudinal edge of the sheet pile must be coplanar and belong to a plane parallel to the neutral axis of the curtain produced.
  • This obligation is the consequence of the profiles, in the form of hooks, currently used to constitute the loops, namely that being each formed on one side of the core of the sheet pile and being turned towards each other, the juxtaposition between two neighboring sheet piles is designed by necessarily placing the sheet piles parallel to each other, so that the male loop of one can cooperate with the female loop of the second and thus constitute the desired lock.
  • US-A-2880589 describes a sheet pile with male and female loops respectively and with ⁇ section of the aforementioned type.
  • the object of the present invention is to remedy these drawbacks and, to this end, it provides a profiled sheet pile with complementary open side loops whose conjugate profiles are such that, to form locks with two adjacent sheet piles of the same type, it is necessary to have said sheet pile upside down.
  • the two mouths of each sheet pile must be placed on one side and the other of the neutral axis of the curtain, and consequently the sheet pile according to the invention makes it possible to obtain very high resistance modules up to 5.5 times the current limit values for equal steel quality.
  • the sheet pile according to the invention makes it possible not only to preserve, but also to improve the sealing properties for which the sheet pile with loops is particularly sought after; in fact, the empty space existing between two locked complementary loops is this time completely closed; this space is also of a larger section than that left by the locking of two sheet piles in ⁇ , so that it leaves a free passage to possible reinforcing tubes with, if necessary, injection of a product d additional sealing in larger quantity.
  • the present invention therefore has as its first object a method of producing a metal sheet pile of the type comprising two complementary open side loops joined by a non-planar central core, said loops being called respectively "female loop” and “male loop” and being formed , by a profiling operation, each on a longitudinal edge of a metal sheet, on the same side of the sheet and such that their openings face each other, said method being characterized in that, at the end or after this profiling operation, the core of the sheet is folded along a single line which extends longitudinally and parallel to the loops, the core then defining a dihedral whose angle ⁇ is obtuse and open in the direction of the openings of the loops.
  • a second object of the present invention is a profiled metal sheet pile of the type comprising two complementary open side loops joined by a non-planar central core, said loops being called respectively "female loop” and “male loop”, said sheet pile being obtained by the aforementioned method and being intended, by juxtaposition with other sheet piles of the aforementioned type with engagement of each of the two loops of each sheet pile in the complementary loop of each adjacent sheet pile, for the production of a curtain, in particular a curtain with a high modulus resistance, the male loop and the female loop being provided on the same side of the core, said sheet pile being characterized in that said core has a single longitudinal fold line which extends parallel to the loops, the core defining a dihedral whose angle ⁇ is obtuse and open in the direction of the loop openings.
  • the two male and female loops are of conjugate profiles, so that after their engagement in the respectively complementary loop of an adjacent sheet pile each male loop-female loop interlocking has at least three contact zones. Due to these mandatory contacts when locking a sheet pile on its neighboring sheet pile, the lock obtained has the advantage of being completely sealed.
  • the profile of the female loop extends in a roundness over approximately 3/4 of a circle and the profile of the male loop forms a first rounding slightly greater than 1/4 of a circle, extended by a dish itself extended by a second rounding extending over approximately 5/8 of a circle.
  • the angle formed by the flat part of the male loop with the web of the sheet pile and the angle presented by the web on either side of its fold line are additional.
  • the outside radius of the second rounding of the male loop is equal, apart from the clearance, to the inside radius of the rounding of the female loop, the contact during interlocking male loop-female loop produced by these rounding, by the intermediate plate of the male loop bearing on the part of the sheet pile core which borders the female loop and by the end of the female loop bearing on the part of the sheet pile core which borders the male loop.
  • the outside radius of the second rounding of the male loop is slightly less than the inside radius of the rounding of the female loop, the contact during the male-to-loop nesting female being carried out by the external extreme point of the male mouth in support on a point of the interior wall of the rounding of the female mouth, by the intermediate flat of the male mouth in support on the part of the core of the sheet pile which borders the female mouth and by the end of the female loop resting on the part of the sheet pile core which borders the male loop.
  • the outside radius of the second rounding of the male loop can advantageously be of the order of 85/100 to 95/100 of the inside radius of the rounding of the female loop; the height of the intermediate plate of the male loop can be substantially equal to 5/6 of the outside radius of the second rounding of said male loop; and the inside radius of the first rounding of the male loop can be substantially equal to half the outside radius of the second rounding of said male loop.
  • the profile of the male loop extends in a rounding over at least 3/4 of a circle and the profile of the female loop forms a rounding over at least 1/2 circle extended by a dish.
  • the angle that forms the flat of the female loop with the web of the sheet pile and the angle that the web has on either side of its fold line are additional.
  • the external radius of the rounding of the male loop is equal, apart from the clearance, to the internal radius of the rounding of the female loop, the contact during the male loop fitting - female loop produced by these rounding, and by the flat of the female loop pressing on the part of the core of the sheet pile which borders the male loop.
  • the angle of the dihedral formed by the core on either side of the fold line is close to 105 °, a value which leads to the best compromise between the height of the sheet pile / width of the sheet pile and which , therefore, provides the best values of resistance modules.
  • the present invention also relates to any sheet pile curtain essentially constituted from sheet piles according to the invention, interlocked head to tail.
  • Each sheet pile (1, 2, 3) has two loops, each formed along a longitudinal edge of the profile, a loop (4) also called “hard loop” because it has a very accentuated roundness, and a loop (5) also called “soft loop” to be more weakly rounded.
  • the loops (4) and (5), each in the form of hooks, have complementary profiles so as to be able to cooperate and lock, respectively on the loop (5) of the sheet pile (3) and on the loop (4) of the sheet pile (2).
  • the loops (4) and (5) are formed on one side and the other of the sheet, the loop (4) being slightly raised by a fold (6), in the opposite direction to that of its formation. , so as to be located at the same height as the loop (5) relative to the plane of the sheet.
  • the sheet is deformed in its central part, along the longitudinal folds (7, 8, 9, 10), so as to form a dome whose top (11) is a plate.
  • the plane passing through the loops (4) and (5) is therefore parallel to the plate (11) of the dome.
  • the engagement of any sheet pile with an adjacent sheet pile of the same type is necessarily carried out by placing the sheet piles parallel to each other, thus it has been shown in Figure 1.
  • the neutral axis (12) of the sheet pile wall (1-3) therefore passes substantially equidistant from the plane of the plates (11) and the parallel plane passing through the loops (4) and (5) multiple interlocked sheet piles.
  • each sheet pile (1) has been profiled being limited, on the one hand, the loops (4) and (5) must necessarily be located on the same side with respect to the neutral axis (12 ) on the other hand, it is understood that the resistance modulus of each sheet pile (1) is necessarily low since, by construction, the height of said sheet pile is necessarily limited.
  • the sheet pile with complementary open side loops has the particularity of having a male loop and a female loop formed on the same side of the sheet during the profiling operation, and such as the openings (36) and (37). loops, female and male respectively, face each other.
  • a female loop (14) and a male loop (15) are formed on the longitudinal edges of the sheet metal, the profiles of which are conjugate and complementary.
  • the profile of the female loop extends from the part (16) of the core (17) which borders it, in a rounding (22) over approximately 3/4 of a circle.
  • the profile of the male loop (15) forms a first rounded (19) slightly greater than 1/4 of a circle, extended by a flat (20) - even extended by a second round (21) extending over approximately 5/8 of a circle.
  • the loops (14) and (15) cooperate mainly by the rounding of the female loop and by the second rounding of the male loop. Consequently, the outside radius of the second rounding (21) of the male loop (15) is slightly less than or at most equal, apart from the clearance, the inside radius of the rounding (22) of the female loop (14).
  • the male loop (15) is placed overhanging the end (18) of the core (17) with a height (H) equal to approximately 103% of the inside diameter of the rounding of the female loop. .
