Definitions

  • the invention relates to an arrangement for conveying concrete for the production of a concrete structure with a concrete placing boom arranged in a height-adjustable manner on a finished part of the structure to be constructed, with a vertical projection over the mast in the area of the upper end of the mast Axially rotatably arranged, consisting of several, preferably about horizontal axes mutually pivotable arms of the delivery boom and with a preferably extending over the height of the mast to the delivery boom and over its arms, which can be loaded with concrete.
  • An arrangement of this type with a height-adjustable concrete placing boom is known, in which the mast designed as a tubular column is set up free-standing on a base at the start of construction, and then two floors of the structure are first concreted.
  • ceiling frames are cast in, through which the tubular column extends.
  • the ceiling frames consist of two halves and can therefore be mounted around the tubular column. They are formed conically in the area of the ceiling and can therefore be dismantled from the finished ceiling.
  • Each ceiling frame is equipped with pawls that can be swung in automatically as well as two mounts for a hydraulic climbing device.
  • the hydraulic climbing device consists of two hydraulic cylinders, two guided on the tubular column Claws and two automatically swiveling pawls for climbing.
  • the tubular column is gradually moved over the ceiling height.
  • an extension piece of appropriate length must be inserted into the delivery line after a predetermined total climbing stroke.
  • the climbing device After overcoming the ceiling height, the climbing device must be removed from the first ceiling, transported to the second ceiling and attached to the tubular column.
  • the ceiling frames released in the lower ceilings can also be moved to the upper floors, for example from the first to the fourth floor. If the load-bearing capacity of a ceiling is exceeded due to the vertical forces exerted on the mast, the ceiling must be supported. At the end the free ceiling openings are closed with a conically designed concrete cover.
  • the known climbing device can be used not only between ceilings but also in a shaft.
  • the ceiling frames are fastened to supports which are supported on the outer walls of the shaft.
  • the known climbing principle cannot be used in structures which have neither ceilings nor shafts. Proceeding from this, the invention is based on the object of developing a concrete conveying arrangement with a height-adjustable concrete placing boom, which can also be used in ceiling or shaftless concrete structures, for example for concreting drilling rigs, without the actual climbing device having to be implemented.
  • the solution according to the invention is based on the idea of having the concrete placing boom climb up on one side on a vertical wall of the finished part of the concrete structure. It should be taken into account that the circuit moving from bottom to top usually has a catwalk protruding over the wall, which must be overlapped on the outside by the mast. This requires a certain distance between the outside of the finished wall and the mast column. To enable this, the following features are provided according to the invention:
  • At least one riser rail which can be releasably attached to a vertical wall of the finished structural part in a vertical orientation
  • At least one support member arranged on the foot boom which can be supported at one of several support points arranged at a grid-like distance from one another along the riser,
  • a lifting device arranged on the foot boom, which is supported with at least one lifting element on the riser rail or at its support points and which gradually moves the mast by moving the supporting element to the next higher support point relative to the finished structural part.
  • console-like support elements for supporting the support member and / or the lifting member are arranged on the support points of the riser rail.
  • the support member and the lifting member can alternately one under the action of a spring in the course of a lifting operation on one of the support points or
  • Support elements preferably have a detachable snap-on foot in the manner of a pawl.
  • a preferred embodiment of the invention provides that the lifting element is designed as a hydraulic cylinder which is fastened or articulated at one end, preferably the upper end, to the foot arm, and at its other, preferably lower free end, which is guided and supported on the riser rail at least the raster distance between the support points corresponding piston hub.
  • the vertical guidance of the foot arm can be achieved in that the foot arm has at least two spaced-apart, vertically guided on the riser rail and behind which to transmit the tilting moment of the mast gripping shoes.
  • At least two riser rails which can be coupled to one another are provided at their mutually facing front ends in their longitudinal direction, forming a rail track.
  • two risers or riser strands arranged next to one another at a lateral distance can be provided, while the boom can have two supporting members and / or lifting mechanisms and / or pairs of sliding shoes arranged at a corresponding distance from one another.
  • the arrangement of the lifting device on the foot boom according to the invention has the advantage that the actual climbing device is raised together with the mast. It therefore does not have to be implemented, as in the prior art, in floors. As construction progresses, only the risers have to be implemented. This can be done with simple means in that at a clearance at least corresponding to the length of the riser above the foot bracket and at a distance below the conveyor boom, a crane device for moving the riser with one on the side of the foot bracket projects beyond the mast.
  • crane boom preferably pivotable about a vertical axis and optionally carrying a trolley, is arranged on the mast.
  • the crane boom can be arranged on the mast in such a way that it reaches into the space beneath the formwork walkway in any sliding position of the mast relative to the circuit and thereby reaches up to the finished concrete wall directly.

Un conduit de transport (18) pouvant recevoir du béton s'étend sur toute la longueur du mât (10) jusqu'à la flèche de transport (12) et sur les bras dont se compose celle-ci. Pour ajuster en hauteur le mât (10), au moins un rail vertical (44) est fixé sur une paroi verticale (46) de la partie finie de la construction. Une flèche (12) qui fait saillie d'un côté sur la zone de la base du mât est verticalement guidée sur le rail (44). La flèche (12) comprend en outre au moins un organe de support capable de s'appuyer sur un élément de support (54) parmi une pluralité d'éléments de support mutuellement espacés le long du rail vertical (44). Un dispositif de levage (64, 68) situé sur la flèche qui s'appuie sur les éléments de support (54) du rail vertical avec au moins un organe de levage (58) permet de lever graduellement le mât (10) par rapport à la structure par déplacement des organes de support (56) jusqu'à l'élément de soutien (54) suivant.
