Definitions

  • the invention relates to a concrete container for placing concrete in Formwork, consisting of a container open at the top with a post bottom tapering bottom with an outlet opening and an adjoining flexible pipe, in particular a hose for distributing the concrete, wherein the container and / or a support frame receiving it suspending means has, with which the concrete container can be attached to a hoist, wherein below the outlet opening of the concrete container is essentially horizontal horizontal spar that can be moved transversely to the free-hanging flexible tube is, the displacement of which is at least approximately the diameter of the flexible Corresponds to the tube and the one below its outlet opening crosses the area and thereby the cross section of the flexible Rohres tapered.
  • formwork is filled with concrete during construction of a building used concrete containers.
  • this concrete container has an outlet opening with a slide flap that can be actuated by means of a pivoted lever.
  • the one on a hoist attached concrete container is placed on the side of a concrete transporter and loaded with concrete via a filling channel. This lifts the concrete container filled in this way Hoist and carry it to the place where the concrete is to be inserted into the formwork is.
  • the man standing by at this point operates the lever to open it the slide valve, and the concrete slips due to its own weight through the outlet opening into the formwork.
  • a contraction valve with a controllable Contains valve body made of an elastic material.
  • the mouthpiece owns two pipes of approximately the same size running in a common longitudinal direction and a hose connecting them from an elastically deformable material, which can be pressed together between the two tubes.
  • An outer tube is with the two inner tubes through axially extending, funnel-shaped Parts sealed together so that an annular space is created, which can be connected to a pressure medium source.
  • a mouthpiece This type has a considerable length and is therefore not suitable for concrete containers suitable, for precisely those reasons that are already above and introductory are discussed.
  • closure known from FR 2 359 262 A1 should also be mentioned.
  • tooth segments are arranged in pairs below the outlet opening of the container and spaced-apart tooth segments are provided, which together comb and one of which is pivotable by means of a lever.
  • Several spars are arranged between the tooth segments forming a pair, whose centers lie on a spiral line. Runs between these spars the flexible hose fixed at the outlet opening, which by swiveling the tooth segments can be squeezed together.
  • This facility is structurally complex and bulky, apart from the fact that toothed segments no suitable components for the rough operation provided here represent.
  • the invention provides that the two ends of the spar, whose length is at least the diameter corresponds to the flexible pipe, using handlebars, ropes or chains on the concrete container are suspended and that articulated springs at the two ends of the Holmes are, whose other ends on the support frame of the concrete container are fixed and the tension springs are tensioned when the spar is to the side of the outflow opening in its position releasing the flexible pipe or its cross section is located and on the spar, preferably in the central area Actuator is articulated, on the other hand with the support frame of the concrete container is connected and with which the spar is movable against the force of the tension spring is.
  • Advantageous embodiments of the invention are in the subclaims captured.
  • the concrete container 1 has an upper, cylindrical section 2 and one at the bottom adjoining, tapered section 3, which down into a Outlet opening 4 opens.
  • Vertical struts 5 with their lower ends an open ring 6 are fixed, form a support frame 7, which the concrete container 1 picks up or with which the concrete container 1 is firmly connected.
  • a flexible tube 8 preferably a rubber elastic Hose attached, the length of which can be several meters and on the lower mouth opening 9, a switch console 10 is arranged, which has a Line 11 is connected to a drive unit 12, which in turn from Support frame 7 is worn.
  • This Spar 15 consists of a shaft 16 on which freely rotatable rollers 17 are mounted are.
  • This spar 15 is located somewhat below the outlet opening 4, expediently in the plane of the open ring 6.
  • a Actuator 18 connected, the other end connected to the open ring is.
  • This actuator 18 can be designed as a piston-cylinder unit or as a purely mechanical component (screw mechanism, threaded rod, gear mechanism or the like.).
  • Tension springs 19 are also located at the two ends of the spar 15 arranged, with their respective other ends facing each other Sections of the open ring 6 are attached.
  • FIG. 1 now shows the position of the spar 15 in which the cross section of the hose 8 is released.
  • the tension springs 19 are tensioned and the actuator 18, the is designed as a piston-cylinder unit, is acted upon. Should be for loading of the concrete container 1 or for transporting the hose 8 is closed are, the actuator 18 is relieved, and by the force of the tensioned Tension springs 19, the spar 15 is pulled to the right (Fig. 1), the hose 8 deformed in the manner shown in FIG. 2, its cross-section tapers and is thus closed.
  • the spar 15 (FIG. 2) assumes this position when the concrete container 1 is filled or transported using a hoist. Hold the force of the springs 19 the spar 15 in its closed position, because during filling or transport the concrete container has no energy supply. Should the concrete container 1 are emptied, the actuator 18 is acted upon and pulls the spar 15 against the force of the springs 19 to the left (Fig. 1), so that the Hose 8 hangs freely at the outlet opening 4, its cross section entirely is open and the concrete in the container is down through the hose can flow out. The tension springs 19 are in turn biased. The rollers 17 on the spar 15 prevent abrasion on the hose 8.
  • the handlebars 14 hold the Spar 15 in its operating position and prevent sagging of the articulated Systems and also relieve the closed hose 8 from that lying on it Concrete weight. In addition, the spar 15 moves on an arc Path between closed and open position, what the folding and closing the hose 8 favors.
  • the drive unit 12 via which the actuator 18 is acted upon, can be supplied with electrical energy, either via supply cables or by means of batteries and accumulators. Other forms of energy, for example Compressed air can be used here. Instead of actuating a switch, the drive unit can 12 can also be controlled by radio.
  • the locking mechanism is essentially maintenance-free and protected against contamination by concrete. Because the closure is constructed that no moving parts can come into contact with the fresh concrete relatively thin-flowing concrete can be distributed without dripping concrete slurry. If a removable switch is mounted at the lower end of the hose 8 or the concrete container is controlled by radio, the hose can be 8 or lower end in wall formwork or climbing formwork systems.
  • the mechanical tension springs 19 ensure that the hose 8 is closed is when no external energy supply is available. Basically is it is possible to use other components instead of such mechanical tension springs to be used, which have a comparable effect or which may result from external energy consumption are actuated. Instead of a just trained one Holmes, as shown and described above, this spar can also be arcuate be designed or loop or ring-shaped. The one for its postponement Actuators provided below the outlet opening 4 are then correspondingly articulated to this spar designed in this way Loop or this ring is then slightly larger than the outside diameter of the Hose 8, so that the hose through this loop or through this ring can sag freely.
