Abstract

Each segment of the bridge has a highway plate (1) at its bottom, to which side walls (2) are articulated. Each highway plate and the side walls have comb-type recesses (3.1,3.2) on adjacent sides. The projections remaining between the comb-type recesses form hinge casings (4.1,4.2). The comb-type recesses and the hinge casings on alternate sides fit into one another. The hinge casings of the highway plates and those of the side walls are articulately connected to one another by hinge shafts (5). They are also provided with locking devices and are formed by insert casings, which in the assembled state engage in the hinge casings of the side walls and of the highway plates.

Description

The invention relates to one formed from bridge segments Trough bridge, with each bridge segment one underlying lane panel and articulated connected to it Has side walls. The trough bridge can a truss structure or solid wall girders be educated.

Since the side walls of a trough bridge of the aforementioned type when transferring loads in the longitudinal direction of the bridge in all They usually have to absorb large upper belt forces be secured against buckling. This happens at permanent bridges in general by the fact that Upper flange at certain intervals with frame-like stiffeners provides.

For mobile bridges that are composed of individual parts stability of the side walls achieved by stabilizing struts at certain intervals are arranged, the top chord support. Such strut designs have the Disadvantage that they are expensive and beyond need additional transport volume.

For example, it is composed of individual parts known mobile bridge, where the carriageway panels and the side walls are box-shaped (EP 0 290 405 A1). To connect the road signs with eyelets are provided on the side walls, each of which two are arranged side by side. Here forms a of the eyelets arranged on a lane board with a a hinge arranged on a side wall, the the bridge parts can be folded together. The second of the eyelets arranged on a carriageway panel aligned when the bridge parts are folded with the second one arranged on a side wall Eyelet. A bolt can be inserted through these two eyelets and thus a rigid connection between the two Bridge parts are manufactured. This bridge is too very complex and requires a considerable transport volume.

A hinge for a long folding joint is also known two bridge parts, each bridge part with as Eyes designated eyelets is provided (DE 34 26 397 A1). Through the eyes of two adjacent bridge parts a bolt is pushed, the length of which is dimensioned in this way is that the bolt is half in one of the eyelets and the other half lies in the neighboring eyelet. Such a hinge is not suitable for tensile forces transferred to.

The invention has for its object a trough bridge To be designed so that they have the disadvantages of known trough bridges does not have a rigid connection between lane panel and Side walls made possible with simple means and that it only requires a small transport volume.

• daß jede Fahrbahntafel und die Seitenwände an den aneinander angrenzenden Seiten kammartige Ausnehmungen aufweisen,
• daß die zwischen den kammartigen Ausnehmungen verbliebenen Vorsprünge Scharnierhülsen bilden, wobei die kammartigen Ausnehmungen und die Scharnierhülsen wechselseitig ineinander eingepaßt sind,
• daß die Scharnierhülsen der Fahrbahntafeln und die Scharnierhülsen der Seitenwände durch eine Scharnierwelle gelenkig miteinander verbunden sind
• und daß die Scharnierhülsen der Fahrbahntafeln und die Scharnierhülsen der Seitenwände mit Verriegelungseinrichtungen versehen sind.

The solution to the problem in a trough bridge of the type mentioned is

• that each carriageway panel and the side walls have comb-like recesses on the adjacent sides,
• that the projections remaining between the comb-like recesses form hinge sleeves, the comb-like recesses and the hinge sleeves being mutually fitted into one another,
• that the hinge sleeves of the carriageway panels and the hinge sleeves of the side walls are articulated to one another by a hinge shaft
• and that the hinge sleeves of the carriageway panels and the hinge sleeves of the side walls are provided with locking devices.

The hinge shaft has the task of the lane panel and to join the side walls together; she serves at the same time as a tension element, while the one inside the other fitted hinge sleeves the thrust connection between the lane panel and the side walls.

By means of the locking devices Side walls - in the raised position - with the Road signs non-rotatably connected.

To minimize the number of loose parts hold, the hinge shafts are through with the hinge sleeves the roadway panels or the hinge sleeves the side walls of firmly connected insert sleeves are formed, the - in the assembled state - in the hinge sleeves of the side walls or in the hinge sleeves of the Intervene in the road signs.

The hinge shafts or Push-in sleeves formed by a hollow profile. The hinge shafts or the insertion sleeves only have light weight.

In one embodiment of the invention, the locking devices formed by the hinge sleeves and the hinge shafts or the insertion sleeves running transversely Have holes through the bolts are put through. This will make it a simple though secure connection between the hinge sleeves and the Hinge shafts and the insertion sleeves created. The Bolts also provide a rigid connection between the carriageway panels and the side walls of the Trough bridge, so that thereby stabilizing the Top belt is guaranteed.

According to another feature of the invention Locking devices formed in that the Hinge sleeves and the hinge shafts or the Insert sleeves are provided with push knobs, the Push knobs of the hinge sleeves and the push knobs the hinge shafts or the insert sleeves interlock.

This also creates a rigid connection between the roadway panels and the side walls in the way allows, for example, the shear flow from the Roadway panels using the push knobs in the hinge sleeve the side walls over the corresponding push knobs in the hinge shafts or insert sleeves be transferred.

Since twisting when the thrust knobs engage one another the sidewalls opposite the lane panel is possible is in a preferred embodiment the invention provided that the length of the Hinge shafts or the insertion sleeves located Thrust lugs approximately the length of the comb-like recesses corresponds and that the hinge shafts or the insertion sleeves when transporting the bridge segments in such a way the hinge sleeves of the carriageway panels and into the Hinge sleeves of the side walls are inserted that the push knobs in the area of the comb-like recesses are so that the side walls face each other can turn the lane boards freely.

The hinge sleeve is used for the condition of use of the trough bridge shifted by half a hinge length, see above that the push knobs of the hinge sleeves with the Thrust lugs of the hinge shafts are engaged.

So that more material is available in the area of the push knobs Absorption of the bolt forces is available are advantageous the holes for the bolts in the area the thrust lugs of the hinge shaft.

According to another feature of the invention is in the field a coupling element of two adjoining bridge segments provided with a round cross section, the Outside diameter is slightly smaller than the inside diameter the hinge shafts designed as a hollow profile or insert sleeves and that in the ends of two abutting hinge shafts or insert sleeves is inserted, the coupling element being such Length that it is at least one each by the hinge shafts or the Push-in sleeves transverse holes for the bolts extends.

This coupling element transfers the to the hinge shafts or the inserting forces of a hinge shaft or an insert sleeve for other.

The coupling element is also expediently a hollow profile is formed.

In addition, it is advantageous that the coupling element in the area of the holes for the bolts with a corresponding reinforcement is provided so that here too, sufficient material to accommodate the Bolting forces are available.

The locking devices for locking the hinge sleeves of the side walls with the hinge sleeves of the Roadway panels can also be formed in that on every lane board in the area of the articulated connection with the side walls - at the level of the road surface - Two next to each other Thrust knobs are arranged, their distance from each other is slightly larger than the thickness of the side walls. At the Push the hinge sleeve of a side wall onto the Hinge shaft or the insertion sleeve of the concerned The thrust lugs form a lane at the same time Guide for the comb-like recess of the side wall.

In a further embodiment of the invention Hinge sleeves of the carriageway panels and the hinge sleeves the side walls are under tension Tension anchor passed through, the tension anchor expediently is designed as a tension rope. By means of the The hinge sleeves of the carriageway panels can be tensioned anchors and the hinge sleeves of the side walls in such a way be biased against each other that under working loads the tensile stresses from the load-bearing capacity are smaller are in the anchor as the prestressing force. This gives the advantage that the tensile stresses in the lower flange are "overpressed" so that lower belt couplings for Absorption of tensile forces can be omitted.

The trough bridge according to the invention can thereby be improved be that the end faces of the carriageway panels and the end faces of the side walls with push pins and are provided with holes which are dimensioned and arranged in this way are that - when assembled - the Push pin of a roadway panel or a side wall in the holes in the adjacent lane board or engage the adjacent side wall. Hereby uniform load transfer is guaranteed.

In a preferred embodiment of the invention The trough bridge are the roadway panels and the Sidewalls offset from each other such that the side walls - with the exception of the first and the last side wall - over half the width of each extend two lane panels. Through this configuration the trough bridge receives a special invention high bending stiffness.
