Definitions

  • the invention relates to a method for producing concrete pipes in a standing mold with a mold space between a core and a longitudinally divided shell and with the mold space bottom and top final molding sleeves, wherein pourable concrete poured into the mold cavity and the concrete pipe after a Setting the concrete is removed from the mold by opening the jacket.
  • the upper mold sleeve must allow casting of the flowable concrete in the mold cavity from above, which requires frontally open upper mold sleeves with the disadvantage that the end faces of the tubular body in the region of the open end faces of the upper mold sleeves must be smoothed by hand, what's more in that the setting behavior of the pourable concrete poured into the mold cavity can hardly be taken into account.
  • the air bubbles trapped in the flowable concrete escape upwards and can escape only partially through the open end face of the upper mold sleeve, so that the air bubbles collecting in particular in the area of the outer peripheral wall of the upper mold sleeve Give rise to undesired air pores in the area of the offset, frontal coupling approaches of the finished concrete pipes.
  • the invention is therefore based on the object, a wet concrete casting process for the manufacture of concrete pipes in the mold space between a core and a shell of a standing mold in such a way that not only the
  • the invention solves the problem by the fact that the flowable concrete is filled with removed upper mold sleeve in a predetermined amount in the mold space and that a closed ring forming upper mold sleeve only after a set time for a predetermined set volume of the cast tubular body between the core and the shell is pressed shaping in the end face of the tubular body.
  • Compression molding of the front-side coupling approach by pressing the upper mold sleeve in the still flowable concrete smooth wall surfaces are formed not only in the peripheral region, but also in the region of the front page.
  • the waiting for the setting process for the cast in the mold cavity concrete and the subsequent forming of the coupling approach requires a filling of the mold space with a predetermined amount of flowable concrete in order to ensure a predetermined length of the concrete pipe to be produced. It must therefore be provided a filling volume, the volume of the produced concrete pipe to the
  • Setting volume can be determined in a simple manner, for example by experiments. In practice, it has been found that already after a few minutes a settlement is present, which allows a compression molding by the upper mold sleeve within a given manufacturing tolerance.
  • the molding of the front-side coupling approach of the concrete pipe to be produced can be supported by rotating the upper mold sleeve during and / or after the impressions in the flowable concrete.
  • Fig. 1 is a mold for carrying out an inventive
  • Fig. 2 shows the mold space between the core and shell of the mold
  • Fig. 3 is a view corresponding to FIG. 2 of the mold after
  • a casting mold for carrying out the wet concrete casting method according to the invention is used for the purpose of carrying out the invention
  • Coupling attachment 8 at the opposite end of the tubular body 7 serves a separate upper mold sleeve 9 in the form of a closed ring which can be inserted coaxially with the mold between the core 2 and the shell 3 with pressure in the annular space 4 and preferably rotated about its axis.
  • both the core 2 and the shell 3 are designed to be split lengthwise. While the jacket 3 has to be pulled radially outward from the concrete pipe to be demoulded, the core is to be drawn in radially inwards from the concrete pipe, in order to release the pipe body 7.
  • Coupling attachment 8 is pressed into the tubular body 7 on flowable concrete, a setting of the tubular body 7 is awaited.
  • the filling level of the mold space 4 according to FIG. 2 decreases from a starting point 10 indicated by dash-dot lines under a compression of the concrete to a level 1 1.
  • the jacket and / or the core can be provided with a vibrating drive.
  • the air bubbles trapped in the flowable concrete can escape upward from the mold space 4 during this setting time, so that the coupling projection 8 is formed without pores with smooth wall surfaces during subsequent impressions of the upper mold sleeve into the flowable concrete between the core 2 and the casing 3. It is only necessary to make sure that the when introducing the upper mold sleeve 9 in the mold space 4 above the tube body 7 collecting air can escape from the mold sleeve 9, which is ensured by the required guide gap between the upper mold sleeve 9 and the core 2.
  • the tubular body 7 can be removed from the mold by the jacket 3 is opened and pulled apart radially outward and the core 2 is radially retracted.
  • the upper mold sleeve 9 may remain on the tubular body 7 during demolding, but may also be removed beforehand.

Abstract

L'invention concerne un procédé pour la fabrication de tuyaux en béton dans un moule de coulée vertical présentant un espace de moulage (4) entre un noyau (2) et une enveloppe (3) divisée dans le sens de la longueur et des manchons de moulage (5, 9) fermant le haut et le bas de l'espace de moulage (4), du béton fluide étant déversé dans l'espace de moulage (4) et le corps tubulaire (7) étant démoulé après la prise du béton par l'ouverture de l'enveloppe (3). Pour pouvoir couler des tuyaux en béton de qualité élevée, selon l'invention, le béton fluide est déversé dans l'espace de moulage (4) en une quantité prédéterminée quand le manchon de moulage (9) supérieur est enlevé, et le manchon de moulage (9) supérieur formant un anneau fermé n'est enfoncé qu'après un temps d'occupation pour un volume d'occupation prédéfini du corps tubulaire (7) coulé entre le noyau (2) et l'enveloppe (3) avec mise en forme dans la face frontale du corps tubulaire (7).
