Definitions

  • the invention relates to a slip formwork device for producing concrete protection walls, comprising a slip form with walls for shaping the concrete protection walls, wherein the slip form a gate and an outlet opening, wherein at the inlet opening, a transition region is formed, which is associated with a hopper, and wherein at least in the transition region two vibrators are arranged at different heights.
  • slipforming devices are used for the continuous production of concrete protective walls. They are also known as offset or inset formwork.
  • the concrete protection walls are also called concrete sliding walls and serve as safety systems in traffic. Above all, they serve to protect the middle strip on motorways. As a result, the opposite lanes of the highways are to be separated from each other to avoid accidents.
  • the sliding formwork devices known from the prior art have a filling funnel into which the concrete for the concrete protection walls is filled.
  • the concrete is compacted by vibrators and introduced into the slipform form via an inlet opening.
  • About the outlet opening of the hardened concrete can be spent from the Gleitschalungsform by the entire Gleitschalungsvoriques is viewed from the outlet opening forth in the direction of the inlet opening is pulled.
  • a continuous production of a concrete protective wall is possible.
  • the compaction of the concrete is usually carried out by vibrators, which are designed as vibrating needles.
  • the vibrators generate vibrations that drive air trapped in the concrete out of the concrete.
  • the concrete can be compressed.
  • the air trapped in the concrete can However, not completely escape, so it can lead to air bubbles or voids.
  • the invention is therefore based on the object, a sliding formwork device of the type mentioned in such a way and further, that a production of stable concrete protective walls is made possible, which have almost no defects.
  • a Gleitschalungsvorutter of the aforementioned type is characterized in that the vibrators are arranged spaced apart in the horizontal direction.
  • the vibrators are arranged unfavorably. It has been recognized that the vibrators interfere with each other. In the known sliding formwork devices, it is favored that a layer with a higher concrete density can come to lie above a layer with a low concrete density. The air in the lower layer can then no longer be expelled effectively because it can not penetrate the upper layer of higher concrete density. Finally, it has been recognized that a simultaneously horizontally and vertically staggered arrangement of the vibrators prevents a higher arranged vibrator disturbs a deeper vibrator in its operation.
  • the staggered arrangement of the vibrators in the horizontal direction always creates channels or regions between the vibrators, by means of which the air inclusions can easily be expelled from superimposed layers of the concrete.
  • the number of defects in the finished concrete protection wall is significantly reduced and their quality significantly increased.
  • the vibrators could be arranged at different heights on an inclined plane having an inclination angle of 16 ° to 47 ° to the vertical. Surprisingly, it has been shown that a selection of Angle of inclination from this range allows to expel air bubbles from concrete particularly effectively.
  • the angle of inclination can be selected from this range depending on the height of the concrete protection wall and the length of the slip form.
  • the hopper could have in the transition region to Gleitschalungsform a slope at which the vibrators are arranged on an inclined plane.
  • the vibrators can be mounted on the slope formed on the hopper.
  • the slope may have an inclination angle of 16 ° to 47 ° to the vertical.
  • the slipform mold can be mounted on the hopper in modular construction. It is conceivable that the slip form in the transition region to the hopper is also formed chamfered.
  • the vibrators could be held by brackets, which are arranged on the hopper.
  • the vibrators could be arranged on the brackets with the interposition of vibration buffers made of rubber. As a result, the vibrations generated by the vibrators are decoupled from the walls of the hopper.
  • the hopper could comprise an armature introduction device which has guide elements within the hopper which extend in the direction of the inlet opening.
  • the arrangement of guide elements within the hopper allows reliable guidance of the reinforcements.
  • the guide elements cause the reinforcements to be positioned in the right place in the concrete protection wall. From the prior art, the problem is known that reinforcements within the hopper or Gleitschalungsform are not positioned by the vibrations of the vibrators in the correct position. Frequently, the reinforcements are not positioned far enough inside the concrete protection wall so that concrete can chip off the finished concrete protection wall.
  • the guide elements could be formed as tubes. Tubes are ideal for guiding metal cables or metal bars. Pipes can be easily cut to a suitable length and positioned in the hopper.
  • the guide elements in the hopper could be supported by vibration buffers.
  • This specific embodiment makes it possible to vibrate the guide elements without causing the walls of the hopper to vibrate.
  • At least one vibrator could be arranged structurally separated from the guide devices on an outer wall of the filling funnel in the amount of the guide elements.
  • the entire hopper can be excited to vibrate.
  • the concrete in the hopper can be transported down.
  • a concrete jam can be avoided.
  • no concrete can settle on the inside of the walls of the hopper.
  • one or more vibrators are arranged on the walls of the filling funnel. The arrangement of a vibrator in height of the guide elements is therefore useful, since there is a particular danger in this area that forms a concrete jam.
  • the introduction device could be assigned at least one vibrator, which is arranged within the hopper on the guide elements.
  • the vibrator is cooled within the hopper by the inflowing concrete.
  • the introduction device could be assigned at least one vibrator, which is arranged inside the filling funnel above the guide elements on an inner wall of the filling funnel.
  • This specific embodiment advantageously effects cooling of the vibrator. Furthermore, the formation of a concrete jam is particularly effectively avoided in this critical area.
  • the inflowing concrete is here distributed directly by the vibrations of the vibrator on both sides of the vibrator. As a result, no concrete can settle on or on the guide elements. It is also conceivable to attach two or more vibrators laterally next to the guide elements. In an arrangement of the vibrator within the hopper is also advantageous that the guide elements must not be stored with vibration buffers against the hopper.
  • the structural design of the sliding formwork device can be simplified thereby.
  • the vibrator may have a mounting portion and a croquttelabsacrificing, wherein the mounting portion is angled relative to the Hinttelabrough.
  • the vibrator thus has a cranked design, whereby the Studttelabsacrificing the vibrator is arranged flat in the hopper and the vibrators act on a particularly large area of the hopper with vibrations and thereby expel air bubbles.
  • cross members may be arranged in the hopper, to which the vibrators are attached.
  • the cross members are preferably fastened by means of a welded connection to the side walls of the hopper.
  • the vibrators are preferably mounted on vibrating buffer hanging on the cross members. This embodiment allows a particularly flexible and variable suspension of the vibrator in the hopper.
  • the guide elements can be fixed to the cross members. As a result, the guide elements are stabilized within the hopper, so that the position of the reinforcement is ensured within the concrete protective wall.
  • the vibrator frequency of the vibrators could be variably controlled or regulated.
  • the vibration frequency can be adapted to the viscosity of the concrete used or to specific structural conditions.
  • one or more vibrators are connected to a control system or a control system which communicates with sensors. The sensors can monitor whether the vibrators actually generate the vibrating frequency which they are to produce in the application.
