Definitions
- the invention relates to a roadway crossing device with the features of
- Road crossing devices which serve to compensate for physically induced movements of walkable or accessible structures such as bridges opposite the directly adjoining roadways.
- the causes of such deformations of bridges are usually temperature changes and creep and shrinkage of the building material used.
- Conventionally, concrete is used to make bridges or comparable walkable structures.
- the deformations are changes in length that are made by the
- Road junction device is a largely tight against water and dirt, easy accessibility during maintenance, as low as possible
- joint support strips are usually installed in the roadway in order to compensate for differences in rigidity between the adjacent roadway and the roadway transition device.
- Forming roadway transition device usually made of corrosion-resistant steel edge strips.
- Roadway crossing devices usually a significantly excessive road surface installation, which is a poor ride comfort when driving over
- Roadway constructions with a so-called buttoned expansion profile can be used to bridge expansion joints up to 100 mm.
- Road edges are each arranged two angle profiles that serve as edge protection. On these galvanized steel profiles two shaped profiles are applied, in which the expansion profile is inserted or buttoned.
- mats-roadway transition constructions which bridge the gap area between the roadway and the adjacent bridge by a ductile and traffic-loaded sealing element.
- the mat constructions have the advantage that they can perform both displacements and twists of the bridge structure with respect to the roadway in all coordinate directions.
- the stiffness of the mat material is crucial for the resistance to movement.
- Mat constructions without intermediate profiles are designed for a smaller range of motion, and are especially for movement joints from 40 to 80 mm overcoming joint width used. For larger ranges of movement up to 200 mm additional intermediate profiles or console constructions are used.
- Mat material is high-quality polymeric materials used, usually chloroprene rubber or natural rubber materials are used.
- the polymeric materials can be reinforced with vulcanized steel elements.

- these road junction devices consist of one or more sealing elements, steel edge profiles and optionally from controlled steel intermediate profiles, which store movable support structures.
- These support structures can be designed constructively from specific scissors elements or from transverse or cantilever beams.
- the number of intermediate profiles results from the absorbable strain travel per sealing profile.
- the roadway area which directly adjoins the roadway crossing device is heavily loaded. It comes usually to cracking of the asphalt and thus to a destruction of the asphalt surface layer as well as damage to the underlying base courses.

- the Brückenendab section 2.1 is enough.
- the Brückenendab section 2.1 forms here, for example, an edge substantially transverse to the longitudinal direction of the road.
- Roadway junction device 1 further comprises a retaining device 3, a plurality of transition elements 4 and rods 5, which are arranged through the transition elements 4 and interconnect the transition elements 4 together.

- the respective opposite, other rod end of the rod 5 5 is fixed with an anchor 7 of the rod 5 in the retaining device 3.
- the rods 5 must consist of a corrosion-resistant building material in this embodiment of the invention.
- Suitable materials for such bars 5 may be, for example, stranded stainless steel strands, rods of plastics or wires of fiber composites.
- the bridge anchors 6 and the retaining anchors 7 of the rods 5 may be formed as composite anchors.
- anchorage systems known per se for anchoring 6, 7 of the bar ends 5.1 or 5.2 can also be used from prestressed concrete construction.
- Fig. 1 an already prepared sliding surface 8 can be seen in Fig. 1, which cut in a region between the retaining device 3 and the Brückenendab 2.1 of the bridge 2 is arranged.
- the sliding surface 8 may be formed by way of example as a bituminous layer on a support layer 13.

- FIG. 4 An alternative embodiment of the connection between a rod 5 and a cuboid transition element 4 is shown in Fig. 4.
- the rod 5 is made of a non-corrosion-resistant building material

Between two adjacent cuboid transition elements 4 each have a transition gap 11 is provided with a gap width 11.1, in which the rod 5 is not embedded in concrete. In the remaining transition gap 11 can surface waters, thawing agents and dirt penetrate, which is why the execution of the rod 5 made of a corrosion-resistant building material to ensure a durable construction is required.

- Transition column 11 and the gap widths 11.1 are in the planning of
- Roadway transition device 1 set suitable. If the gap width 11.1 is smaller than originally provided in the production of the roadway transition device 1, compressive stresses occur in the rods 5 or, depending on the design, also in the cladding tubes 9 and in the grouting mortar 10. In the design of the roadway transition device 1 is therefore to consider whether the compressive stresses can be absorbed by the rods 5, or whether a scheduled stability failure occurs, which would result in earlier closure of the transition gap 11 adjacent the bridge 2. In an embodiment with cladding tubes 9 and grout 10 further care must be taken that the tensile stiffness of the roadway transition device 1 is not too large under compressive stress in the rods 5.
- Roadway transition device 1 are compared with a reinforced concrete rod, which can occur under tensile stress cracks.
- the change in length of the reinforced concrete rod under tensile load is approximately equal to the sum of the increases in the crack widths.
- the concrete pieces between the cracks are subjected to a certain tensile stress by means of composite stresses which are conducted from the reinforcing rod into the concrete pieces, they therefore exhibit strains.
- the tensile stiffness of the concrete pieces between the cracks is many times greater than that in the cracks

- FIG. 11 shows, in a detail view A according to FIG. 10, on an enlarged scale the approximately trough-shaped prefabricated elements 14 which are already filled with filled concrete 15.
- Each rod 5 is in each case in direct contact with the filling concrete 15 and connected thereto in a stationary manner.
- the rod 5 is in each case freely movable, which contributes to the desired correspondingly large deformations of each rod 5 within its freely movable guided sections under tensile or compressive load.
- the gap widths 11.1 thus adapt in each case to the prevailing voltage conditions. A jerky, delayed opening up of the transitional gaps 11 together with an associated peak load of the continuous asphalt surface layer 12 is thus prevented.
- the trough-shaped prefabricated elements 14 each from two or more individual trough-shaped prefabricated elements 14 and these multiple precast elements 14 each strung together on their faces or end faces 14.3 in the longitudinal axis direction 14.1 on the sliding surface 8 to connect with each other.
- appropriate sealing measures is to be ensured in this case that at the joints between juxtaposed

- the individual juxtaposed trough-shaped precast elements 14 on the reinforcement and the filling concrete 15 with each other to a continuous, approximately cuboidal

- the production of two roadway transition devices 1 according to the invention, each with seven cuboidal transition elements 4 arranged next to one another, adjacent to the two, has been described with reference to FIGS. 6 to 11
- the number of built in the roadway transition device 1 cuboid transition elements 4 may therefore be between 1 and 100.
- the transition elements 4 in the illustrations Fig. 7 to Fig. 11 have approximately the same size. It may be advantageous to produce the transition elements 4 with different sizes and to carry out, for example, the adjacent to the bridge 2 transition element 4 with an increased width.
- Roadway transition device 1 are also used in building construction as well as in civil engineering, if a passable or a walk-in construction surface at
