Definitions
- the invention applies, in a general way, to the realization of medium-span metal bridges, for example a few tens meters, but is especially suitable for bridge construction for military purposes or the rapid reconstruction of a bridge destroy.
- bridges made of easy prefabricated elements to set up by a team of some men.
- This type of bridge called, in France, bridge "Bailey” includes supporting elements longitudinal members made of lightweight lattice girders and elements transversal bearing a decking. Given the large number of elementary pieces, the establishment of a Bailey bridge is quite long and the result is not very aesthetic but it does not matter in the case of military operations.
- the engineering units have, for some time, to operate in war-torn areas, to reconstruction of infrastructure, particularly crossing, which have often been destroyed. Often only the apron has been cut, abutments and batteries remaining in place.
- the subject of the invention is therefore a new bridge deck which, like the dismountable bridges previously known, is constituted prefabricated elements assembled on the site but whose implementation using lifting devices can be particularly fast, such an apron may, in addition, be more important than temporary bridges known until now.
- the bridge deck according to the invention has a external appearance similar to that of a conventionally built bridge.
- a temporary bridge according to the invention can therefore easily be transformed into a definitive work.
- the invention is not not limit the achievement of temporary bridges but may advantageously be applied to the realization of any work of medium range crossing.
- the invention therefore applies, in a general way, to the realization of a steel bridge deck having at least one span resting on two supports, said apron comprising at least two main beams parallel to a longitudinal direction of the bridge and connected by a plurality of transverse struts spaced from each other, and a transverse decking resting on said main beams longitudinal.
- each longitudinal beam is formed by butt-joining a series of elements prefabricated metal formed each of a tubular hollow box to polygonal cross section having at least one upper face plane, said boxes having the same section and each extending over a length compatible with the means of transport and lifting.
- the caissons of two adjacent beams are connected in pairs by a plurality of spacers each consisting of a metal tube having two ends each provided with fastening means with a side face of a box and said beams are connected to their part upper, by a plurality of rigid transverse junction elements constituting at least a part of the decking and having two ends fixed respectively on the flat upper faces of the caissons of two beams.
- each box forming an element of longitudinal beam has a quadrangular cross section and, preferably, trapezoidal, having two horizontal faces of widths different and two side faces inclined symmetrically with respect at a vertical median plane of the box.
- the elements transverse junction consist of a series of sections separated from each other and extend transversely over a length of less than the distance between two beams, said sections having each two ends respectively fixed on the upper faces planes corresponding boxes of the two beams.
- the joining profiles are separated from one constant distance corresponding to the width of a wooden cross placed between two adjacent profiles and resting on the upper faces planes of the corresponding caissons of the two longitudinal beams, one Provisional deck thus consisting of a series of sleepers next to each other.
- the apron includes a series of corrugated panels extending between two beams longitudinal and resting on the upper faces of the caissons corresponding beams, said panels being joined and constituting a lost formwork for the pouring of a concrete slab forming the decking of the deck.
- the temporary deck consists of sleepers placed between joining profiles
- each box is provided with upward projecting parts, forming connectors, intended to be embedded in the concrete slab poured onto the formwork lost, for the joining of said slab with the beams longitudinal.
- the elements transverse joints consist of a series of slab elements made of concrete to be laid together, one after the other, on at least two series of boxes forming at least two beams longitudinal, covering these, each element of the slab being solidarized, after laying with the corresponding boxes of the two beams, so as to form the decking of the deck.
- the invention also covers a number of advantageous features which will be described in more detail by the which are the subject of the subclaims.
- the invention also covers the elements prefabricated for the construction of a bridge deck and a new method of constructing a bridge span comprising such an apron.

- caissons made from sheets of different thicknesses depending on the loads and overloads that depend on the nature of the traffic.
- the thickness (e) of the lower face 12 it is interesting to vary the thickness (e) of the lower face 12 so as to be able to choose the advance of the caissons likely to withstand the loads applied, given the scope of the span to be achieved and the position of the box compared to the supports.
- the height (H) of the box 10 can be, respectively, 600, 700, 800 and 900 mm.
- the height (e) of the lower face may vary from 20 to 75 mm.
- the first range of boxes with a height of 600 mm will allow to achieve spans with a range of 10 to 20 m while the latest range, having a height of 900 mm, will achieve spans with a range of 20 to 25 m.
- the design of the span in particular the low number of elements and their simplicity, allows them to be assembled from very simple way, for example by bolting. Because of this, it is possible dismantle the bridge to recover the elements, for example after reconstruction of a permanent bridge.
- a construction by bolting or riveting is easier to perform and does not require a personnel as specialized as for welding, which is particularly advantageous for military applications.
- each end of a spacer tube 2 is provided, in its median plane, a fixing plate 21 which is applied on a gusset 22 fixed in a transverse plane to the lateral face 13 of the casing plate 21 and the gusset 22 being provided with orifices which come in alignment for installing fixing bolts.

- each box 10 forming an element of a Longitudinal beam is provided at each end with four massive 23 welded, on the outside, at the four corners of the box whose soles 11 and 12 have been extended laterally.
- These parts massive 23 are each drilled with a bore 24 so that the parts 23a, 23b placed respectively at the ends facing each other two adjacent beams 10a, 10b apply to one another, the bores 24a, 24b being aligned.
- the structure carrying a first route of A circulation and it is possible, if necessary, to build, next to this one, a second supporting structure for a second way of circulation B.
- both beams 1, 1 ' are then secured by junction elements such as that profiles 3 having a length at least a little longer than the distance between the two adjacent beams 1, 1 'and whose ends are fixed on the upper faces 11, 11 'thereof.
- This phase II is shown at the top right of Figure 1. It was thus possible to realize quickly and economically a span temporary bridging using simply a lifting gear of a power of a few tons.
