Definitions

  • the present invention relates to a bridging device in the center-beam construction for a building joint between two structural parts with at least two each associated with a structural part edge profiles and at least one center carrier is disposed between the edge profiles and on at least one of the building structure bridging traverse.
  • such devices are used to bridge building joints between two parts of the structure, in particular between two bridge parts such as a bridgehead or abutment and a bridge support or bridge girder or adjoining bridge girder so that vehicles and animals safely from one component to another component can reach.
  • the construction joints also called movement joints or expansion joints, serve to compensate for movements of the building parts to each other, so as to avoid damage or destruction of the building parts.
  • the size of the building gap is therefore chosen so that the building parts in the course of their use with the greatest possible probability do not touch.
  • the movements that the building parts experience in the course of their use can be divided into two categories, namely in proper movements in use and extraordinary movements due to rare load effects. Movements in the state of use occur almost constantly, regularly and / or permanently.
  • the movements of the state of use include, for example, movements that are caused by thermal expansion or result from creeping and shrinkage of the materials used.
  • this also movements from burdens include, resulting from the use of structural parts, such as caused by passage of people and / or vehicles traffic loads, braking loads when braking vehicles, wind loads, etc ..
  • Extraordinary movements are relatively rare. In most cases, it is larger movements from burdens such as earthquakes, building ground movements, explosion loads, loads from the impact of objects or vehicles, etc.
  • Bridging devices for building joints which compensate for such movements of the building parts are known from the prior art in various embodiments.
  • a proven form of a lock-up device is known as the center-carrier construction or lamella design variant.
  • the bridging device has at least one center carrier, which is fixedly arranged on at least one traverse mounted rotatably and / or displaceably on the adjacent building parts. If the building gap to be bridged is larger, the bridging device has a plurality of center supports, which are each connected to their own crossbar.
  • the trusses are usually installed in so-called truss boxes in the respective building part.
  • control devices act on the trusses of the respective center carrier and keep the variable distances between the individual center carriers or to the edge carriers largely constant.
  • Such controls are formed for example by spring chains, scissors or with the help of so-called pivoting traverses.
  • additional safety devices can be used on the bridging devices as separate components. These safety devices release in different ways additional way for the movement of the building parts in the building joint.
  • the bridging device according to the invention is thus distinguished from the above-described bridging devices in that it has at least two center supports, which arranged on a common cross member in a fixed in use state distance to each other shear-resistant are. Furthermore, the invention is characterized in that the connection between at least one center carrier and the traverse in the manner of a predetermined breaking point is formed.
  • This approach is based on the idea to orientate the number of movable center support in the bridging solution mainly on the size of the movements of the building parts in use and not as usual today on the size of the maximum pathways to be included in extraordinary movements or loads.
  • the solution according to the invention has the advantage that significantly fewer functional parts are required for the control of the distances of the center girders.
  • significantly fewer functional parts are required for the control of the distances of the center girders.
  • the entire construction is thus more economical to perform, has a longer life and low maintenance than the known from the prior art bridging devices.
  • the executed in the manner of a predetermined breaking point connection between traverse and center girder is designed so that it fails in an extraordinary movement of the building parts to each other.
  • the introduction of force necessary for triggering the predetermined breaking point is effected by touching the center support with an adjacent edge profile and / or an adjacent center support.
  • connection can be made so that the failure force is reliably predefined and minimized. Furthermore, this also results in a staggering of the extent of damage in extreme events, since the connections of the individual means carriers successively and not fail simultaneously. Ultimately, so can the dimensions of the lock-up device can be minimized, since the truss boxes can be made significantly shorter, since the lock-up device releases targeted by own deformation path in the building joint and no longer has to be designed for much larger movements.
  • the executed in the manner of a predetermined breaking point connection is designed as a positive, non-positive and / or cohesive connection.
  • the connection may be a welded connection, a bolt connection or even a connection with clamps.
  • the non-positive connection has the advantage that it can be upgraded after a extreme event with relatively little effort.
  • the failure force for example, by tightened with different force bolts can be variably adjusted.
  • At least one center support is additionally secured against lifting so that it remains lying on the truss or trusses after an extraordinary movement of the structural parts and the associated failure of the predetermined breaking point or predetermined breaking points.
  • the backup can be done in a suitable manner, for example, by claws, straps, ropes or the like. Consequently, the bridging device remains traversable even after a Extermereignis especially for rescue workers with even increased security.
  • the edge profiles and / or the center support profile impact surfaces which are designed so that at least one center support is guided in an extraordinary movement of the building parts to the top of the lock-up device.
  • the profile impact surfaces of an edge profile and a center support or adjacent center support can be performed alternately bevelled, so that there is a ramp-like impact surface over which the center support is guided at force application to the top. This allows additional path to be released during an extraordinary movement.
  • the distance between adjacent center carriers fixed in the use state lies in the range between 40 mm and 100 mm. It is also advantageous if the variable distance between an edge profile and the adjacent center support and / or between two mutually displaceably mounted center supports amounts to at least 0 mm and a maximum of 100 mm. These distances have emerged as suitable especially at road junctions, with a large distance a particularly economical and the smaller size requires a particularly comfortable overrunning lock-up device.
  • the bridging device has at least one safety device associated with a structural part, which permits a further movement of the structural parts closing the structural joint to one another when the connections designed in the manner of a predetermined breaking point have failed. This therefore releases an additional path that is available for particularly violent events, such as very strong earthquakes. This additionally protects the structural parts against damage.

  • the edge profile and the center girder are feasible after failure of the predetermined breaking point on the ramp from the lock-up device. This ensures that the traverse remains after an extreme event within the lock-up device, and only the edge profile and the center carrier are guided out of the lock-up device. After the event, the participants telmatic and the edge profile are pushed back into the lock-up device, whereby the Kochfahriana is restored.
  • the predetermined breaking point between the edge profile and the ramp is designed for a greater force introduction, so that initially the connections between the center beams and the traverse fail before the predetermined breaking point of the edge profile fails. Otherwise, the safety device would trigger too early.
  • the safety device has a cover part, which is flat with the upper side of the structural part, between the ramp and the edge profile, wherein the cover part can be guided out of the bridging device. As a result, the safety device is easy to drive over in use.
