Definitions

  • the invention relates to a metal beam adapted to produce a component of the span of a bridge.
  • FR-A-2,858,338 a metal bridge whose span is made from prefabricated elements. Such an element is formed by connecting, by spacers, metal beams. Two parallel beams and connected by spacers form a carrier element of a decking constituting the span. The number of connected load-bearing elements, and therefore of beams, corresponds to the width and the length of the span to be produced. These carrier elements are thus adapted to be easily connected by abutment, depending on the length of the span.
  • Each beam comprises a bottom flange and an upper flange in the form of an elongate, flat and narrow plate.
  • the soles are kept parallel and connected by a metal box constituting the main body of the beam.
  • the ends of the box, square or rectangular section, are equipped with connecting members for abutment beams between them.
  • each box is equipped at the bottom sole of several rounded legs each provided with a through hole and disposed parallel to a longitudinal axis of the box.
  • Two parallel tabs delimit between them a female connecting member, namely a housing for receiving a tab of complementary shape equipping the end of a box of another beam and forming a male connecting member.
  • Each end of the box is thus provided with three tabs forming a female connecting member and a male connection member.
  • the ends of the upper sole are adapted to allow the soles, when two beams are butted, to bear against one another.
  • connection is made between two prefabricated carrying members of specified length and width.
  • Such a construction involves a predefined orientation of each beam so that the connecting members of the male and female type are located in the lower part of the span, once the abutting beams. Despite the wedging performed by the upper flanges, the abutment length of such beams is limited. At the level of the connection zone between two beams, when the abutment length is maximum, each end of the caissons of the abutment beams must rest on an intermediate pillar.
  • FIG. 10 shows a beam comprising a box with a square cross section, and a support block disposed on the box. The end of this beam is equipped with a pair of hinge elements in the lower part.
  • EP-A-0 396 196 describes another variant of metal beam, designed to make the span of a bridge.
  • the end of the beam is equipped with a male connecting member and a female connecting member. These connecting members are arranged in the corners of the lower flange of the beam.
  • the invention proposes to produce another type of beams to form a carrier element constituting the span of a metal bridge allowing the realization of long span length while reducing the number of intermediate support points.
  • the subject of the invention is a metal beam adapted to produce a constituent element of the span of a bridge and comprising two flat flanges, said lower and upper, held parallel to each other by a configured core.
  • a configured core in box with square or rectangular cross-section, characterized in that one end of the core of the beam is equipped with a male connecting member and a female connecting member arranged at mid-distance between the two bottom flanges and higher.
  • connecting members located in a median position on one of the ends of the box and alternating a male connection member and a female connecting member, it is possible to connect the beams together by ensuring a rigidity of the connection between beams such that it requires only one intermediate fulcrum of one or the other end of the abutment beams.
  • the figure 1 represents a beam 1 according to the invention.
  • This comprises a main body or core formed by an elongate metal box 2, with a square cross section.
  • the box 2 is rectangular in cross section.
  • This box 2 connects two parallel soles called bottom flanges 3 and upper 4.
  • the flanges 3, 4 are formed by flat, elongated plates, whose width and length are slightly greater than those of the box 2.
  • Ribs 5, known in self and illustrated in particular to the figure 1 are fixed on a portion of the side faces 6 and 7 of the box 2. They are arranged regularly and perpendicularly to a longitudinal axis A of the box 2.
  • the ribs 5 extend outwardly of the box perpendicularly to the faces 6 and 7.
  • the casing 2 is divided into several compartments by internal partitions 50, shown in dashed lines at Figures 1 and 2 . These partitions 50, parallel to the ribs 5, contribute to the rigidity of the box 2.
  • An end 8 of the box 2 is provided with two ribs 51, disposed on each face 6, 7 and connecting the flanges 3 and 4 over the entire height H of the box 2, at the corners thereof.
  • orifices 52 allow the fixing of spacers.
  • the ribs 51 are configured as flat bars. These ribs 51 are equipped, on one side, legs 510, triangular. These struts 510 connect the ends of the ribs 51 to the soles 3 and 4.
  • the other end 80 of the beam, to the left looking at the Figures 1 and 2 is provided with male and female connecting members 800 and 810 known from the state of the art.
  • the end 8 of the box 2 comprises, in the extension of the lateral faces 6, 7 of the beam core, that is to say the box, to the left of the ribs 51 while looking at the figure 1 two plates 9, 10.
  • These plates 9 and 10 extend over the entire height H of the box 2 and connect the soles 3 and 4. They are perpendicular to the ribs 51.
  • a plate 9 is fixed on the end of a face 6 of the box 2 thus extending the latter. It comprises, in the middle position, a male type connecting member.
  • This male member 11 is formed by a tab generally of triangular shape, the base 12 is in the extension of the plate 9.
  • the base 12 is integral with the material plate 9.
  • This male member 11 is thus disposed substantially to mid-distance between the lower soles 3 and upper 4. It extends partially beyond the soles 3 and 4, towards the outside of the volume of the box 2.
  • This lug 11 has a rounded tip 13 which extends beyond the plumb with the ends 300 and 400 of the soles 3 and 4.
  • the top 13 is equipped with a through 14 orifice, circular, whose center is substantially located in a plane P of the box 2.
  • the plane P is the median longitudinal plane of the caisson 2.
  • the orifice 14 is arranged so that its center is substantially in line with the ends 300, 400 of the flanges 3 and 4.
  • a female type connecting member 15 is mounted on the plate 10 located in the extension of the face 7, opposite that 6 equipped with the male member 11.
  • the female connecting member 15 is formed by two tabs 150, 151 of shapes and dimensions similar to those of the tab 11.
  • the tabs 150, 151 are fixed on either side of the plate 10, for example by welding, gluing or bolting.
  • the dimensions of the space E formed between the two tabs 150, 151 are adapted to form a receiving housing, with minimum clearance, of a male-type tab 11 carried by the end 8 of a box 2 of a other beam. In other words, the width of the space E is substantially equal to the thickness of the tab 11.
  • the tabs 150, 151 are also located substantially mid-height of the box, at the same level as the tab 11. They are also each provided with a circular orifice 140, 141 whose center is also in the median plane P of the box 2
  • the orifices 14, 140, 141 of the male members 11 and female 15 of the same box 2 are aligned.
  • the male members 11 and female 15 are arranged so that their respective orifices 14, 140, 141 are also aligned when a tab 11 of a box 2 is inserted between the legs 150, 151 of another box 2.
  • the plate 10 is provided with a hollow 16, dotted visible to figures 1 and 5 , located at the bottom of the space E and adapted to receive the top 13 of a lug 11 when inserted between the tabs 150, 151.
  • the lower sole 3 comprises a cutout 17, in this case of rectangular shape, allowing access from below the beam 1, looking at the figure 5 at the connection zone between two butted beams.
  • the cutout 17 is formed in the end 300 of the sole 3, between the plates 9 and 10.
  • This cutout 17 allows the introduction of a jack allowing the removal of connecting rods 19, 20.
  • These bars, section circular, are inserted on a provisional basis. They allow guiding the ends 8 of two beams to butt. Once these are connected and held in position by pins, not shown, inserted into the orifices 14, 140, 141, they are removed, as shown in FIG. figure 4 . Alternatively, they remain in position.
  • These gutters 18 are arranged parallel to the longitudinal axis A of the beam 1 and they open on either side of the struts 510. They allow, as is shown in particular to Figures 5 to 7 , the insertion, temporarily, connecting rods 19, 20.
  • the latter used to align the orifices 14, 140, 141 to set up the connecting pins in the orifices of the abutment beams.
  • cylinders not shown, are introduced into the gutters 18. These cylinders push the bars 19 out of the gutters 18. To remove the bars 20, the installation of cylinders is not hindered by the presence a sole 4 and does not require a gutter.
  • the ribs 51 are provided at the level of the connection zone with the lower sole 3 of an orifice allowing the passage of a connecting bar 20, similar to the bar 19.
  • the shape of the tabs forming the male and female connecting members is different.
  • they are rectangular and / or the number of through holes for the insertion of pins is different.
  • Such an arrangement of connecting members between two abutting beams, with provisional connecting bars 19, makes it possible to produce long lengths of abutting beams, with a minimum deflection between the beams and with a reduced clearance between two beams.
  • the rigidity of such a connection makes it possible, on the one hand, to produce large span lengths and, on the other hand, requires only a fulcrum on one or other of the ends of the beams 1 splines, when the length of the span requires an intermediate support point.
  • Such a configuration is represented in figure 4 .
  • the rigidity of the connection facilitates the establishment of the span by jetting, especially for long span lengths.
  • the caissons of the beams intended to form the lateral edges of the span are, as illustrated in FIG. figure 8 , provided with a longitudinal bar 21.
  • This bar 21 is disposed on a face 6 or 7 of the box 2, parallel to the longitudinal axis A of the box 2. It is located in the vicinity of the upper flange 4, on the face 6 or 7 of the box 2, said outer face.
  • This bar 21 is not fixed directly on the face 6 or 7 of the box but held in position by several bent supports 22, configured in L.
  • These supports 22 comprise a square section tube 220, one end 221 is fixed to the bar 21, for example by welding.
  • the tube 220 is connected perpendicular to the bar 21.
  • a plate 222 provided with orifices 223 is mounted in the vicinity of the other end 224 of the tube 220.
  • This plate 222 is fixed, for example by bolting, on the ribs 5, 51.
  • the supports 22 are regularly distributed over the entire length of the box 2 and support the bar 21 which extends over the entire length of the box 2.
  • This bar 21 thus forms a support for bases 23 adapted to receive posts 24 constituting a protective barrier.
  • a base 23 is shown on the right of the figure, in the form of a square plate provided with four orifices 25 distributed at the corners of the plate. In a variant, the shape and / or the number of orifices are different.
  • the base 23 is illustrated to the right of the figure 8 , in premounting position, facing a foot 26, of complementary shape of a post 24. This foot 26 is bolted to the base 23, as shown in the left part of the figure 8 .
  • the bases 23 are fixed, for example, by welding, on the bars 21, more precisely on a so-called upper face 210, oriented towards the span of the bridge when the beam 1 is in position.
  • the fixing the bases 23 is advantageously carried out on site, the bars 21 and the supports 22 are also fixed on the box 2 by bolting on site. In another embodiment, the bars 21 and the supports 22 are fixed on the box in the factory.
  • Such a configuration allows mounting, in situ, the barriers that are provided on site, this from standard prefabricated elements. It is therefore no longer necessary to specifically manufacture boxes to support posts 24 corresponding to each type of barrier. Any box is able to be equipped with any type and / or the number of posts 24 barrier, according to the regulations of the area where the bridge is installed.
  • Such a bar 21 may also be mounted a posteriori, on a box 2 of a beam 1 of a bridge already in place, provided that the box is equipped with ribs similar to the ribs 5 and 51.
  • Such an assembly makes it possible, in the event of an impact in the barrier, to preserve the structure of the bridge, irrespective of the type of barrier mounted on the bar 21.
  • the posts 24 themselves which deform or even which give way under the shock, or it is the connection between the bent support 22 and the bar 21, de facto the plate 222, which deforms or breaks, or the connecting bolts between the various elements that yield that without it there is a modification of the structural strength of the caisson 2, therefore of the span of the bridge.
