Definitions

  • the invention relates to an apparatus for producing a Hohlbau ⁇ stone from a hydraulically curing, wet building block mass with an upwardly open mold, the upstanding inside mold walls of a Formbo ⁇ , spaced laterally spaced core webs to form hollow chambers of the hollow block comprises, and with a movable along a guide over the form of filling carton, which forms a limited by peripheral walls receiving space with a sieve bottom for Aus ⁇ bring the recorded building block mass.
  • the output quantity of block mass depends on the speed with which the filling carriage is moved over the mold. If, for the purposes of loosening the applied building block mass, the filling car is provided with a sieve bottom, the irregularities which occur can not be reduced, but can not be avoided.
  • the invention is thus based on the object, a device for len len manufacture of a hollow brick of the above-described Arts so that a uniform filling of the mold with moist building block mass as a prerequisite for over the cross-section consistent mechanical properties Eigen ⁇ properties of the hollow block to be produced can be ensured.
  • the invention solves this problem by the fact that the sieve bottom vibrationally mounted in a vibratory drive ange ⁇ is closed and different sized sieve openings with a free passage of the wet building block mass according to their own weight interrupting opening cross-section in one of the course of the peripheral walls of the receiving space and / or the mold walls and the arrangement of the core webs has dependent distribution over the shape of the cross-section and that the Medwa ⁇ gene is locked in a stop-limited filling position on the mold.
  • the invention is based on the finding that non-uniform application conditions result due to the internal friction of the wet building block mass and the friction between the building stone mass and the friction between the building block mass and the peripheral walls of the receiving space. For this reason, to compensate for these irregularities of the sieve plate is provided with different sized sieve openings. With these differently sized screen openings, however, not only the uneven compensation conditions of the block mass from the receiving space of the charge truck but also uneven filling conditions in the area of the shape can be taken into account by the distribution of the differently sized screen openings over the shape cross section as a function of the course of the Peripheral walls of the receiving space and the mold walls and the arrangement of the core webs of the mold is selected.
  • the filling of the mold with the building block mass of the filling carriage must occupy a vorge ⁇ given filling position relative to the mold.
  • the filling of the mold may only be made in the filling position of the filling carriage.
  • FIG. 1 shows a device according to the invention for producing a hollow component in a section in the region of the Biwa ⁇ located in the filling position gens in a simplified plan view and
  • Fig. 2 shows this device in a section along the line H-II of Fig. 1st
  • the device for producing a hollow block on an upwardly open mold 1, which consists of a mold bottom 2 and a 3 placed on the mold bottom * 2 Formka ⁇ .
  • core webs 4 are used, which pass through the mold bottom 2 and can be pulled out of the mold space by means of a punch 5 for demolding the hollow component through the mold bottom 2.
  • a guide 6 is provided which comprises two lateral guide rails 7 for the rollers 8 of a filling carriage 9.
  • This guide 6 forms stops 10 for a Filling position of the filling carriage 9 above the mold 1.
  • an actuator 11 for example, a control cylinder, with the aid of the filling carriage 9 can be locked in the stop position.
  • the filling carriage 9 forms an upwardly open receiving space 12 for a hydraulically hardening, moist building block mass, from which the hollow building block is manufactured.
  • the receiving space 12 is delimited by peripheral walls 13 and a sieve bottom 14, which is mounted to oscillate in a displacement guide 15 of the filling jig 9 and is connected to a vibration drive 16.
  • This vibration drive 16 is designed as an eccentric drive and has an eccentric 18 driven by an electric motor 17, to which a connecting rod 19 engaging the sieve bottom 14 is articulated.
  • the Anlenkach- se 20 for the connecting rod 19 is mounted radially adjustable on the eccentric 18.
  • the vibration frequency can be adjusted via the electric motor 17, so that the sieve bottom 14 can be adapted in a simple manner with respect to its vibration excitation to the respective requirements with respect to the structural mass of the stone.
  • the sieve bottom 14 is formed as a grid and has different sized sieve openings between the individual bars, as can be seen in particular in FIG. 1.
  • the cross-section of the sieve openings is limited upwards in order to prevent a free passage of the moist building block mass through the sieve bottom due to its own weight.
  • Only in the locked filling position of the Schwingungs ⁇ drive 16 is turned on for the sieve plate 14 to deploy the block mass from the receiving space 12 in the located under the sieve tray 14 Form 1.

Abstract

L'invention concerne un dispositif servant à fabriquer un bloc de construction creux à partir d'une masse de construction humide hydrauliquement durcissable, lequel dispositif comprend un moule (1) ouvert vers le haut, lequel moule comporte des traverses centrales (4) placées à une certaine distance latérale les unes des autres, s'élevant d'un fond (2) du moule à l'intérieur de parois de moule et servant à former les chambres creuses du bloc de construction creux, ainsi qu'un chariot de chargement (9) pouvant être déplacé le long d'une coulisse (6) au-dessus du moule (1), lequel chariot forme, avec un fond à tamis (14) permettant de répartir la masse de construction reçue, un espace de réception (12) délimité par des parois périphériques (13). L'objectif de cette invention est de parvenir à un chargement uniforme du moule (1). A cet effet, le fond à tamis (114), installé dans le chariot de chargement (9) de manière oscillatoire, est relié à un entraînement oscillatoire (16) et comporte des ouvertures de tamis de différentes tailles présentant une section transversale d'ouverture entravant un passage libre de la masse de construction humide suivant le poids propre de cette dernière, lesquelles ouvertures sont agencées au-dessus de la section transversale du moule selon une répartition qui dépend de la forme des parois périphériques (13) de l'espace de réception (12) et/ou des parois du moule et de l'agencement des traverses centrales (4). De plus, le chariot de chargement (9) peut être verrouillé au-dessus du moule (1) dans une position de chargement délimitée par butée.
