Abstract

A roadway joint device for providing a drivable joint section between a road and an adjoining structure, particularly a bridge structure, includes at least one joint element placed on a sliding surface adjacent to the bridge structure. A longitudinal axis of the joint element is arranged substantially parallel to a plane of the roadway and a bridge end section of the bridge structure. Joint gaps with a specified gap width are arranged between the joint element and the adjoining bridge end section and/or an adjoining retaining device arranged at a distance to the bridge end section. The joint element is attached to at least one rod, the rod being arranged substantially in the direction of the longitudinal axis of the bridge structure, anchored at one rod end in the bridge structure and another rod end thereof in the retaining device.

Dependent claims

A roadway joint device (1) for providing a drivable joint section between a road and a drivable adjoining structure, in particular a bridge structure (2), wherein the various deformations of the road and the adjoining structure may be compensated by the roadway joint device (1), wherein there is placed on a sliding surface (8) adjacently to the bridge structure (2) at least one joint element (4), wherein each joint element (4) comprises at least one prefabricated element (14) that has a recess (14.2), which recess (14.2) is filled with filling concrete (15), wherein the longitudinal axis (4.1) of the at least one joint element (4) is arranged substantially parallel to a plane (16.1) of the roadway (16) and substantially plane to a bridge end section (2.1) of the bridge structure (2) and joint gaps (11) with a specified width (11.1) are arranged between the at least one joint element (4) and the adjoining bridge end section (2.1) and/or an adjoining retaining device (3), which is arranged at a distance to the bridge end section (2.1) within or underneath the plane (16.1), wherein the at least one joint element (4) is attached to at least one rod (5) by way of compound effect between rod (5) and joint element (4), whereby compound tensions may be transferred from the rod in a uniformized way to the at least one joint element (4) attached thereto, said rod (5) being arranged substantially in the direction of the longitudinal axis direction of the bridge structure (2) and being anchored in the bridge structure (2) at one rod end (5.1) thereof using an anchoring (6) and in the retaining device (3) at the other rod end (5.2) thereof using an anchoring (7).

A method for producing a roadway joint device (1), comprising the following steps:

-a- producing at least one prefabricated element (14) having one or several recesses (14.2), wherein the prefabricated element (14) is preferably produced substantially trough-like;
-b- where required, transporting the at least one prefabricated element (14) to an installation location;
-c- placing the at least one prefabricated element (14) with each of the recesses (14.2) thereof facing upwards on a sliding surface (8), wherein the sliding surface (8) adjoins a bridge end section (2.1) of the bridge structure (2) as well as a retaining device (3), which is arranged at a distance to the bridge end section (2.1) within or underneath a roadway (16);
-d- aligning the at least one prefabricated element (14) on the sliding surface (8), wherein a longitudinal axis (14.1) of the prefabricated element (14) is aligned substantially parallel to a plane (16.1) of the roadway (16) as well as substantially parallel to the bridge end section (2.1) and wherein between the prefabricated element (14) and further adjoining prefabricated elements (14) and/or the adjoining bridge end section (2.1) and/or the adjoining retaining device (3) there is placed respectively one joint gap (11) with a specified width (11.1);
-e- anchoring at least one rod (5), which is guided substantially transversally to the direction of the longitudinal axis (14.1) through each prefabricated element (14), using at one rod end (5.1) thereof an anchoring (6) in the bridge structure (2) and at the other end (5.2) thereof an anchoring (7) in the retaining device (3);
-f- sealing the feedthrough points on the internal surfaces of each recess (14.2), at which the at least one rod (5) is guided through each prefabricated element (14), using respectively one sealing (21) and
-g- filling the recesses (14.2) within each prefabricated element (14) with filling concrete (15) to respectively one joint element (4).
