Definitions

  • the present invention relates to a sliding formwork for the construction of supporting walls with a reinforced floor for the fixing of slopes or for the formation of free-standing earth walls as soundproof walls
  • a first type consists of a visible sign, a bottom wall and two side walls protruding from the sign to the rear.
  • Another type is a square box with four side walls without a bottom.
  • EP-A-0 668 405. it is provided to manufacture a prefabricated part such that a prismatic body is formed with a support element as the base element and two, with the support element and two side walls. A grid mat is placed in this body and the body thus covered is filled with earth material. The grid mat forms on one edge of the Body a loop into which a support rod can be inserted for transport and which serves as a retaining attachment on site by folding onto the rear triangle.
  • a sliding formwork made of a stable, rigid material with a trough-like design, comprising a front wall with an angle corresponding to the angle of inclination of the slope or the earth wall to a floor wall said bottom wall with a recess in the longitudinal direction up to half the length of the formwork and an at least approximately perpendicular guide rib on the bottom wall as the end of the bottom wall over the entire length of the formwork.
  • sliding formwork in the construction of retaining walls, such as, for example, slope fixings or as a soundproofing wall, is characterized by inserting a first reinforcing means into the formwork above the first area with the recess in the floor and a second, same reinforcement in the adjoining area, with a part of the reinforcement hanging over the front wall, filling the formwork over the first area up to the height, filling the first area of the formwork up to the height of the front wall and backfilling the area behind the formwork and covering it with the Reinforcing agent after the filling material has solidified, then pulling the formwork forward until the second batch of reinforcing agent comes to rest over the first area of the formwork and inserting a third locking agent in the second area of the formwork and repeating the filling process with the first batch of formwork and the second batch of reinforcement.
  • FIG. 1 is a perspective view of an exemplary embodiment of the sliding formwork
  • FIG. 2a is a perspective view of the sliding formwork according to Fig.l, with inserted reinforcement
  • 2b - 2e each show a view from the left in FIG. 2a showing different expansion stages
  • 3 shows a side view of the sliding formwork according to FIG. 2 in a sliding formwork which is advanced around an installation unit
  • FIG. 4 shows a sectional view through a steep slope reinforcement, produced using the sliding formwork according to FIG. 1,
  • FIG. 5 shows a sectional view through a soundproofing wall, produced using sliding formwork attached on both sides.
  • the sliding formwork 1 shown in FIG. 1 is formed from approximately 5 mm thick sheet metal or a correspondingly strong composite or plastic or wood and comprises a front wall 2, a bottom wall 3 with a recess 4 in the longitudinal direction of the sliding formwork 1.
  • This recess 4 cuts out a section from the bottom wall 3, which extends to approximately half the length of the bottom wall and allows a narrow support 3a to exist on both sides.
  • the sliding formwork 1 has a guide rib 5.
  • the guide rib 5 has a guide reinforcement 6 in the direction of the transverse wall 11, in that the height of the guide rib 5 rises to the same height as the front wall 2.
  • the bottom wall 3 has on the outside of the transverse wall 11 a skid 7 and on the guide stiffener 6 and on the front wall 2, for example 7 a pulling hook 8 is attached, to which a pulling rope can be attached in order to pull the sliding formwork 1 away.
  • a reinforcing means 9, 10 such as a geo-mesh, or a geotextile or another bendable mesh, inserted.
  • This insertion of a reinforcement 10, which was not used at first, in front of the reinforcement 9 used is done for the purpose that any slipping material can be used as a filling in a later process step.
  • an intermediate reinforcement reinforcement aid 12 can be inserted as shown in FIG. 2c in order to achieve good anchoring with the filler material located behind the sliding formwork 1. Further material is now filled onto this reinforcement aid 12 until the same height as that of the front wall is reached in the sliding formwork 1 (FIG. 2d). After solidification has taken place by tamping or shaking or some other known method Procedure, the part of the reinforcement aid 9 initially placed over the front wall 2 is placed over the filling in the sliding formwork 1, which is then again placed over the backfilling located behind the sliding formwork (FIG. 2d)
  • the slip formwork can be placed on this lower layer at a later time in order to obtain a further height level.
  • the sliding formwork 1 can be pulled forward on the hooks 8.
  • the frictional force between the reinforcement aid 9 filled with earth material is very large and the shaped wall attachment remains in the intended position.

  • FIG. 5 shows a sectional view of a soundproofing wall with a two-sided embankment wall.
  • a pre-green biomat or another known mat can also be inserted behind the reinforcing means 9, 10 so that the greening takes place immediately or at least very quickly.

Abstract

L'invention a pour objet la stabilisation des talus ne nécessitant pas de corps préfabriqués sur site tout en offrant les mêmes avantages et en permettant la réutilisation du matériau d'excavation en vue de réaliser des économies de temps et d'argent. Pour ce faire, on utilise un coffrage (1), en forme de cuve, réalisé dans un matériau stable et indéformable. Ce coffrage (1) comprend une paroi antérieure (2) formant avec la paroi fond (3) un angle correspondant à l'angle d'inclinaison du talus ou de la levée de terre. La paroi fond (3) mentionnée est pourvue d'un évidement (4) s'étendant dans le sens longitudinal jusqu'à environ la moitié du coffrage (1) et d'une nervure de guidage (5) s'élevant sur la paroi fond (3) de façon au moins approximativement perpendiculaire sur toute la longueur du coffrage (1) et faisant office de terminaison latérale de la paroi fond (3).
