Definitions

  • An assembly for forming silos or like vertically elongated containers involves a segmented scaffold slidably supported on at least one centrally disposed guide rod and a circumferential casting shell formed of inner and outer shell pieces which are supported by the scaffold via rod and suspension eye units that permit limited horizontal movement between the rod and eye elements.
  • the inner and outer shells are vertically slotted to permit size alteration and release from a layer of cast concrete and repositioning for a new layer at the next higher step in the upwardly progressive formation of the concrete container.
  • the invention relates to a shell for the production of container shaped concrete constructions such as silos or the like in which two shell pieces are provided spaced from one another by the distance corresponding to the wall thickness of the container, formed displaceably in the direction of their central axis and peripherally closed, wherein the shell pieces are arranged directly or indirectly on a common carrier fitted with guide elements and this carrier is held displaceably on at least one guide rod.
  • Shells are also already known in which two shell pieces are provided spaced from one another by the thickness of the wall of the container and formed displaceably in the direction of their central axis and peripherally closed.
  • the lifting of the shell pieces is effected by hydraulic installations or 'by means of a toothed rod drive.
  • the hydraulic equipment however raises the price of such shells and is associated with a greater expenditure of assistance.
  • the object of the invention is to create a shell for the production of containers, especially silos or the like, which can be set up, displaced and removed by a single operator.
  • the shell according to the invention moreover the afore-mentioned disadvantages will be avoided.
  • the carrier is formed as a traversa'ble platform and a hand or motor winch or other lifting means is fitted on the carrier for displacement thereof along the guide rod.
  • the formation according to the invention bring with it a safe working surface, since the opening required for the container is always closed off.
  • the concrete can be poured in from the platform with transportable containers. Since the hand or motor winch or other lifting means is arranged on the carrier this can easily 'be serviced from the platform, so that the formation, displacement and removal of the shell, can be carried out by a single operator.
  • FIG. 1 shows a section of the shell and the carrier
  • FIG. 2 a plan view of the shell and the platform
  • FIG. 3 a view of the suspension eyes and a spacing holder
  • FIGS. 4 and 5 a plate forming the platform or the support for the same;
  • FIGS. 6, 7 and 8, the connecting or tensioning of the shell pieces
  • FIG. 9 one possible method of connection between individual guide rods; 7
  • FIG. 10 a clamping jaw on a reinforcing iron
  • FIG. 11 a protection screen arranged on the exterior shell piece.
  • the shell consists of an outer shell piece 1 and an inner shell piece 2.
  • the two shell pieces 1 and 2 are hand or strip shaped and formed peripherally closed, and v are made from one or more pieces screwed together.
  • the shell pieces 1 and 2 are directly or indirectly connected with a carrier 3, this carrier 3 being held by means of a collar 5 on a guide rod 4 lying in the central axis of the shell pieces.
  • the carrier 3 is provided with rails 6 which in this embodiment lead radially outward and serve as support for the plates 7 which form a transversable platform 8.
  • Rods '9 are secured to these plates 7 by means of brackets 10 and engage in the suspension eyes 11 and 12 on the shell pieces 1 and 2 and accordingly' hold the shell pieces 1 and 2.
  • the peripheral contour of the platform 8 corresponds approximately to that of the wall 16 so that at any time the correct circular form of the container is given through the arrangement of the distance holder 13 on the peripheral contour of the platform 8.
  • a handwinch 17 is illustrated in FIG. 1 as the drawing means for the lifting and lowering of the shell pieces or the carrier, wherein by shortening of the traction cable 18, which is led over a cable roller at the upper end of the guide rod, the shell 1, 2 and the carrier 3 and accordingly the platform 8 are lifted up.
  • a lever 19 is pivotally mounted on the carrier 3, which lever is provided at one end with a ring 19 embracing the guide rod 4 with only slight play.
  • the end of the traction cable 18 is secured to the zone opposite to that of ring 19' in relation to the bearing 19".
  • a spring 19" acting oppositely to the cable traction is attached to a free end of the lever. If traction is now applied to the cable 18 then the spring 19" etfects a tilting of the ring 19' so that the carrier and thus the shell pieces cannot fall downwardly.
  • the ring On raising the carrier the ring is however pressed on the collar 5 in the horizontal position, so that it cannot tilt this and accordingly exerts no braking action.
  • FIG. 3 shows the construction of the suspension eyes 11 and 12 as well as the distance holder 13.
  • the suspension eyes 11 and 12 are formed as slots in the peripheral direction (longitudinal slots 20, 21) so that the shell pieces on release or on tensioning or screwing can move in the peripheral direction of the wall.
  • the rod 9 is secured to the plate or to the rail 6 by means of a bracket 10.
  • the individual plates 7 for construction of the platform 8 are provided with lateral straps 22, 23 which prevent lateral displacement in relation to the rails 6 (FIGS. 4 and 5).
  • the plates are made from wood the individual planks 24 being connected with the straps 22, 23.
  • connection at a break in the outer shell piece 1 is effected by means of a key 26, which has key-shaped springs 27 which engage in grooves 25 provided on the shell piece.
  • the shell piece 1 is thus drawn together (FIG. 6).
  • grooves 28, 29 each extending over the breadth of the shell piece 2 are provided, the depth 30, 31 of the grooves 28, 29 running at an acute angle to the vertical. These grooves are formed to receive a plate 32, the side zones 33 of which lie at an acute angle to one another. A nose 34 at its upper part is arranged for the lifting out and insertion of this plate (FIGS. 7 and 8).
  • FIG. 10 shows a clamp 36 which is secured to a vertically running reinforcement rod 37.
  • This clamp 36 serves for regulation of the advancement height of the shell pieces 1, 2.
  • tubular members 38 can be welded or riveted on the outer shell piece 1, for the fitting of a protective screen.
  • a rod 39 is provided which by means of eyes 41 carries a protective wire or tube 40.
  • the procedure in the handling of the shell is as follows: At the central axis of the silo to be erected the guide rod 4 is anchored or erected.
  • the carrier 3 can now be fitted on the rod 4 to which the rails 6 are to be secured.
  • Brackets 10 are provided on the plates to receive the rods 9 after the application of the outer and inner shell pieces 1, 2.
  • These rods 9 now connect the brackets 10 arranged on the plates 7 with the suspension eyes 11 and 12 of the shell pieces 1 and 2.
  • the shell pieces now hang on the carrier 3 which is held on the guide rod 4.
  • tensionin-g of the shell pieces the following is provided:
  • the piece 1 is tensioned through the key 26.
  • the inner shell piece is pressed apart by means of the wedge shaped plate 32, which is engaged in or pushed into, a groove on a break of the shell piece.
  • the distance holders 13 are mounted on the shell pieces 1, 2, which additionally lie on the peripheral contour of the platform.
  • the shell can as a rule be made ready for the next strip-like moulding after one or two days.
  • the gauging of the vertical construction of the silos can be taken care of on these clamps, for example by means of a water level which is laid on two such clamps. According to the height of the building work further rods are fitted on or inserted in the rod 4 which lies at central axis of the shell.
  • the procedure can now begin again.
  • the shell pieces are tensioned and the distance holders fitted on.
  • the for mation of the shell requires only a short time and can also be carried out by a single operator which is not only a great advantage from the price point of view but also from the viewpoint of safety and working technique.
  • a toothed rod is provided, on which the carrier is raised up by means of toothed wheels. Furthermore the rod need not lie at the central axis and several guide rods can be applied according to the size of the silo.
  • the shell according to the invention is obviously adapted not only for the production of silos but also for other container-like structures or structural parts.
