Definitions

  • the invention relates to a bridge abutment, a bridge structure with a corresponding abutment and a method for producing a bridge abutment and bridge structure.
  • the invention also relates to a precast concrete part for use in a bridge abutment according to the invention.
  • Bridge abutments are currently mostly made of reinforced concrete.
  • reinforcements are introduced in the area of the base plate, the wing walls and the bridge abutment and then the bridge abutment is created using in-situ concrete. Extensive formwork work is necessary for this. After the bridge abutment has been poured, the formwork must be dismantled.
  • the construction of such a bridge abutment and a bridge structure with a corresponding bridge abutment is time-consuming. In particular, when a bridge structure is built over an existing traffic route, long construction times lead to long-lasting and costly impairments of the traffic running under the bridge structure to be built.
  • Bridge abutments can also be created from precast concrete parts or using precast concrete parts. So shows CN 107313339 A a bridge abutment that uses prefabricated elements such as the base, stand, support bank and wing walls as well as connecting segments made in in-situ concrete.
  • CN 108442239 shows a bridge abutment that is created entirely from precast concrete parts.
  • the precast concrete parts are made of ultra-high-strength concrete (UHPC - Ultra High Performance Concrete) and are connected to the bridge abutment by means of prestressed steel rods.
  • the object of the present invention is to provide a bridge abutment and a corresponding bridge structure that is reliable and durable and can be produced quickly.
  • a further object of the invention is to create a method for producing a bridge abutment and a method for producing a bridge structure with which it can be erected quickly. This is desirable both for new bridge structures and when replacing existing bridge structures. In particular, the impairment of any traffic routes leading under the bridge structure should be reduced in terms of time.
  • this object is achieved by a bridge abutment according to claim 1.
  • a precast concrete part correspondingly designed as a wing wall element for a bridge abutment is therefore also the subject of the invention.
  • the object is achieved by a bridge structure which comprises at least one bridge abutment according to the invention, as well as by a method for producing a bridge abutment and a method for producing a bridge structure.
  • the wing wall is formed by one or more precast concrete parts.
  • this part of the wing wall preferably the entire wing wall, does not have to be cast on site, but can be created from one or more prefabricated components. This shortens the construction time for a corresponding bridge abutment or bridge structure.

These further components of the bridge abutment are the abutment wall and the base plate of the corresponding bridge abutment.
  • connection creates a reliable and permanent bridge abutment or bridge structure.
  • the connection can be made in that the precast concrete reinforcement of the precast concrete element at least forming the wing wall is connected to a reinforcement of the base plate and / or abutment wall via a connection connection and / or that the corresponding reinforcements of the base plate and / or abutment wall are at least also formed by the precast concrete reinforcement .

  • the formwork remains part of the abutment or bridge structure, with the advantages of a reduced time requirement mentioned in the previous paragraph.
  • the bridge abutment preferably has a deep foundation connected to the base plate.
  • the deep foundation can be easily connected to it.
  • the ability to connect the base plate to a deep foundation is a great advantage compared to bridge abutments, which are built exclusively from prefabricated parts, since there a connection with a deep foundation is not possible or only possible with great effort.
  • the abutment wall reinforcement and / or the base plate reinforcement are preferably also formed by at least one unlocked part of the precast concrete reinforcement.
  • a precast concrete part is created which has a reinforcement part protruding over a section created in concrete, namely the unlocked part.
  • This is preferably arranged in such a way that it is arranged in the area of the abutment wall and / or base plate to be created in in-situ concrete and at least also forms the abutment wall reinforcement and / or base plate reinforcement when the bridge abutment is being built.
  • a reliable connection between the abutment wall and the wing wall element and / or the base plate and the wing wall element or the corresponding reinforcements can be created in a simple manner.
  • the introduction of reinforcement for the abutment wall and / or base plate is facilitated, which in particular reduces the effort the time required to create a corresponding bridge abutment or bridge structure is further reduced.

  • Formwork element which is designed as a precast concrete part.
  • the outwardly facing end face of the abutment wall is that side which faces away from an earth dam running behind the bridge abutment.
  • a formwork element designed as a precast concrete part remains on the abutment wall according to the principle of lost formwork.
  • the formwork element thus forms part of the abutment wall.
  • the entire formwork of the abutment wall is created on the outwardly facing end face of the abutment wall in just one formwork process, possibly using several formwork elements. As a result, the construction time for a corresponding bridge abutment according to the invention can be reduced again.

  • the construction time of a suitably designed bridge abutment can thus be significantly shortened once again.
  • Connections between the individual prefabricated reinforcement elements and between the abutment wall reinforcement and the precast concrete reinforcement only need to be established on site. This can be done via a corresponding connection connection and / or by connecting the reinforcement element and an unlocked part of the precast concrete reinforcement that also forms part of the abutment wall reinforcement.
  • the invention comprises a correspondingly designed precast concrete part, which is intended for use as a wing wall element and can be used as a formwork element of an abutment wall and a base plate of a bridge abutment, the precast concrete part connecting connections for easy connection to an abutment wall reinforcement and a base plate reinforcement of the bridge abutment having. No work is required on site for an otherwise necessary subsequent installation of connection elements in the precast concrete part.

  • the section designed as a formwork element can in this case preferably have the corresponding connection connections or unlocked parts of the precast concrete reinforcement.

  • Bridge abutments according to the invention and corresponding bridge structures can thus also be built using a corresponding precast concrete part as a wing wall element by the method according to the invention as follows:
