Definitions
- the subject of the present invention is a bridge part forming horizontal crosspiece.
- the invention relates to a part structure of bridge forming horizontal crosspiece, in particular for the construction of a bridge in removable Warren beam steel.
- FR-A-2320388 describes a bridge piece forming a horizontal crosspiece in the position of use, comprising a vertical core having an upper edge and a lower edge, and upper and lower wings respectively secured to said edges and perpendicular to said core.
- bridge should be understood in broad sense and not be limited to the bridge building sector road, rail or other vehicle support in the sense that commonly heard.
- An object of the present invention is to provide bridge parts forming horizontal crosspieces which can be connected and secured easily with other necessary side beam members for the construction of a structure such as a removable steel bridge.
- each end of the core has a connection set to additional structural elements, each connection assembly comprising a first vertical plate integral with one end of the core and orthogonal to said core, a second plate parallel to said first plate and integral with said core and arranged at a distance h from the first plate towards the median zone of the core, and a third horizontal plate integral with the lower edges of said first and second plates, said first, second and third plates being able to receive organs of fixing of additional structural elements.
- the core each has its ends a recess in such a way that the upper edge of the core has a length equal to that of the bridge part to the nearest thickness said end plates, and the bottom edge has a length scaled down.
- the weight of the bridge part can be reduced, and by the recesses, ensuring the passage of the constituent elements of the beams side.
- the second plate of each connection assembly is integral with the core in its portion comprising the recess, whereby the portion of the core comprised between the first and second plates of the same connection set a reduced height.
- the bridge piece consists of a vertical core 12 which preferably comprises, as best shown in Figure 2, a recess 14, 16 at each of its ends, these recesses corresponding to only part of the height total soul. Consequently, the core has an upper edge 18 of which the length is equal to that of the bridge piece and a bottom edge 20 of reduced length due to recesses 14 and 16.
- a first wing or upper wing 22 is welded to the upper edge 18 of the core while that a lower wing 24 is welded to the lower edge 20 of the core.
- the wings are perpendicular to the core 12, the current section of the piece of bridge also having an I shape. We would not leave the invention if we directly used an I-shaped straight section iron.
- connection assembly 26 consists of a end plate 30, of trapezoidal or rectangular shape, perpendicular to the plane of the web and welded to it and to the wing upper 22.
- the plate 30 is full.
- Connection set 26 has a second plate 32 identical to plate 30 and parallel to this one.
- the plate 32 is integral with the core in the zone having the recess 14.
- the plate 32 is provided with a slot for the passage of the core 12. This plate 32 is also welded to the wing upper 22 and on the core 12.
- connection assembly 26 is completed by a third plate or bottom plate 34 which is parallel and in the extension of the lower wing 24.
- the plate 34 which is rectangular, is welded to the lower edges 30a and 32a of the first and second plates 30 and 32. Plate 34 is also welded to the end of the lower wing 24 of the bridge part. Plates 30 and 32 have the same height as the core 12.
- the plates 30, 32 and 34 all have the same width which is greater than that of the wings 22 and 24.
- the spacing between the plates 30 and 32 is sufficient to allow the placement of the end of the structure members. This spacing is for example of the order of 450 mm.
- two pairs of flat bars parallel to wings 22 and 24 are welded respectively on either side of the core 12. More specifically, a first pair of irons 36 and 38 is welded between the first and second plates 30 and 32 while a second pair of irons 40 and 42 is welded beyond the second plate 32.
- FIGS. 1 to 3 the fixing holes for the different additional members to simplify the figure. These holes are provided in the plates 30, 32 and 34 of each of the assemblies 26 and 28.
- the lower plates 34 of the sets of connection are used not only for fixing members additional but also to the stiffening of the vertical plates 30 and 32. It can also be seen that the recesses 14 and 16, which are provided at the ends of the core 12 of the bridge piece, not only allow to lighten this one as already indicated, but they allow release a greater free volume in the sets of connection between plates 30, 32 and 34.
- bridge piece 10 which has just been described with its two connection assemblies, can be easily prefabricated since it consists only of parts common type of metal which are preferably joined together by welding.
- each transverse bridge piece 10 is bolted to each of its ends on a pair of members obliques 50, 52 made for example of folded sheet metal and whose ends are bolted to the plates 30 and 32 forming the sets of bridge piece connection.
- the plates 30 and 32 are drilled for receive the fixing bolts of the members.
- the plates 34 are drilled to allow bolting of members and bracing of the structure.
- All oblique members 50 and 52 associated with the different bridge parts 10 constitutes the two planes longitudinal verticals of the side beams of the bridge. This set is repeated with a number of bridge parts 10 sufficient to satisfy the length of the bridge to be made.
- the upper ends of the members obliques 50, 52 are fixed on connection plates such as 54, for example by bolting.
- connection plates 54 are connected to each other along the length of the bridge by U-shaped irons folded sheet referenced 56.
- the rigidity and inertia of each of the parts side decks of the bridge are brought by longitudinal angles 58 thus forming a member.
- Each module thus constructed is braced by two sets of two oblique angles, one of the games being vertical and referenced 60 and the other set being horizontal and referenced 62.
- the deck of deck 64 rests on the spacers and is made up of a steel plate stiffened by buckets.
- the decking is used for rolling cars.
- the transverse bridge parts forming a spacer are planned for one or two lanes. The dimensions of the bridge parts of course are defined according to the track width.
- the elements of the bridge part are of metal, especially of steel. We would not go out of the invention if the bridge piece was made of another material such as a material composite.
