Definitions

  • This invention relates to an adjustable panel for shuttering curved walls which incorporates substantial novel and inventive features in comparison with what is presently known.
  • the adjustable panel for shuttering curved walls to which this invention relates is of the type comprising bodies of sheet steel or beams of substantially open trapezoidal cross-section located in the direction of the generatrices of the curved surfaces attached to the laminar member or shuttering plate which will adopt the curved shape required for the wall which is to be built and in which the trapezoidal bodies are connected together in an articulated way to permit adjustment of the mutual angular arrangement of the said bodies or trapezoidal beams in order to fit the desired curve.
  • U.S. Patent 7048249 discloses a shuttering of adjustable circular type in which adjustment of the angular arrangement of each pair of adjacent trapezoidal beams is brought about through intermediate tensioners articulated to the said beams and positioned along the same. For this, multiple points of connection positioned along the length of the beams are used in such a way that multiple tensioners are needed in order to bring about individual adjustment of each length of each beam. This is very cumbersome and somewhat unsatisfactory work given that there is no mechanical link between the various devices for adjusting each individual beam.
  • an adjustable panel for shuttering curved walls in which the shuttering can be quickly adjusted to the desired curve by working on a very small number of adjustment points in a synchronised way along each beam in the form of a generatrix for the shuttering, in such a way that adjustment can be achieved quickly with great uniformity of curvature in the direction of the height of the shuttering panel, avoiding warping of the latter as a result of loss of parallelism between generatrices.
  • this invention provides synchronising shafts which act on the top and bottom parts between two curved shuttering panel beams parallel thereto in such a way that through the action of a single transverse shaft of hexagonal structure two longitudinal parallel shafts are brought into action simultaneously and through articulations act on a number of adjacent beams, with the result that for example from a single adjustment point it is possible to adjust the position of the two adjacent beams, that is to say the curvature of two segments or panels of the laminar shuttering element each lying between two successive beams can be adjusted simultaneously. In this way it is possible to bring about quick and effective adjustment of the shuttering and avoid deformation due to warping of the surface of the curved shuttering by synchronising the top and bottom parts of the panel.
  • the synchronising shafts may be shafts which rotate about their own geometrical axes or preferably may be in the form of crankshafts rotating on an eccentric axis determined by their upper and lower pivots, which provides more favourable construction as regards resistance to the forces generated.
  • the shuttering curved walls to which this invention relates comprises multiple panels joined together by means of clamps each of which can be curved as shown in Figure 1 , comprising the laminar element which can be shaped into a curve -1- and various beams -2- of special cross-section which will be described below attached equidistantly to laminar element -1-, with the arrangement being supplemented by beams -3- for each of the edges located to the left and right of the panel illustrated respectively.
  • the various panels -1- may be connected vertically through clamps -4- and horizontally through clamps -7- as will be explained in greater detail below.
  • An essential feature of the adjustable panel for shuttering according to this invention is synchronisation of the adjustment of the radius of curvature of element - 1- through aligning the adjustment elements along the generatrices of the panel in order to avoid warping of the latter with loss of parallelism between generatrices.
  • This is achieved through the provision of shafts -5- parallel to the panel beams with one located between each two beams as illustrated in Figure 1 .
  • These longitudinal shafts -5- can be rotated through the action of adjustable length arms -6- which are housed in one of beams -2- and act directly on two adjacent longitudinal shafts -5-, and through the articulations which will be explained the latter act on the side walls of the adjacent beams.
  • each arm -6- which is adjustable for length has an external structure that is preferably hexagonal prismatic as this corresponds to a commercially-available section and has internal openings - 8- and -9- threaded in opposite directions in which threaded rods -10- and -11- are respectively housed in such a way that rotation of arm -6-, for example by means of a spanner from the exterior, brings about inward or outward movement of the respective housings for threaded rods -10- and -11- in mutually opposing directions.
  • These rods are articulated through their ends -12- and -13- to corresponding extensions of shafts -5- which are indicated by number -14- and which may be double or single.
  • Arm -6- is fixed with the ability to rotate in one of beams -2-, for example, through the arrangement illustrated in Figures 3 , 7 and 9 through collar -15- and the corresponding groove, although it should be understood that this could be achieved through any other type of assembly incorporating an enclosing bushing, bearing, etc.
  • the slotted openings are in the form of an arc of a circle centered on the inside face of the shuttering panel, so that the length of the arc of circumference between two generatrices is maintained constant throughout the range of adjustment.
  • connection between shafts -5- and beams -2- is similar to that described for the top through connecting rods -20- which are not shown at the top, together with wings -19- and transverse bars -17-.
  • the synchronisation shafts can rotate about their own geometrical axes or preferably they may be arranged as crankshafts as illustrated in the figures, preferably in Figures 4 , 9 and 12 .
  • shafts -5- are mounted in the form of a crankshaft through wings -34- articulated through vertical pivots -35- which give rise to an eccentrically rotating shaft.
  • Mounting a shaft -5- in the form of a crankshaft is also illustrated in Figure 15 and in the cross-section in Figure 16 , and it will be seen that the arrangement is the same at the top and the bottom.
  • Figures 17 and 18 show the articulation between one of synchronisation shafts -5- and adjacent beam -2- through intermediate connecting rods -36- in such a way that rotation of the said synchronisation shafts is transmitted to said adjacent beams -2-.
  • Beams -2- have a special structure which can be seen especially in Figures 6 to 9 and 12 .
  • the said beams have a central column with a prismatic or similar structure which imparts great rigidity to the beam and that in the situation illustrated in the figures they comprise a pentagonal prismatic structure with side faces -25- and - 26- substantially perpendicular to laminar shuttering element -1- and another two faces -27- and -28- which are inclined with respect to side faces -25- and -26- and a further face -29- perpendicular to said side faces -25- and -26- and substantially parallel to laminar element -1-.
  • the beam is supplemented by two oblique wings -30- and -31-secured to laminar shuttering element -1- by means of flanges and bolts.
  • the said columns strengthening the beams are provided with openings for clamps or other types of access such as upper longitudinal openings -32- and "tightening eye” openings -33- and others of the like.
  • Figures 13 and 14 show details of the construction of side beam -3- of the open type which has straight faces, giving rise to a general prismatic structure which on its front face has a longitudinal opening -46- for the insertion of one of the jaws of a clamp providing a vertical joint between an adjustable wall panel and another located at the top as will be seen in the detail in Figure 11 .
  • the front face of beam -3- has a longitudinal abutment -45-designed to limit the transverse position of the clamp so that the arms thereof do not interfere internally with beam -3-.
  • the beam has a stepped plate -37-joined by flanges -38- and -39- on its edges, preferably by laser welding, to the front face of beam -3- and the edge -40- of side face -47- of beam -3- respectively.
  • On the edge of the other side -48- of the beam there is a second flange -41- of structure similar to that of flange -39-, and through this arrangement laminar shuttering element -1- is attached by means of bolts -42- as will be seen in Figure 14 .
  • the beam is attached to laminar shuttering element -1- partly through bolts -42- mentioned which attach flange -41- and partly through long transverse bolts -43- which pass through the beam and are incorporated in the front face of shuttering element -1-through a widening head -50- which is flush with the said panel.
  • Bolts -43- are fixed by nuts -49- which like bolts -42- can be accessed from the interior of the shuttering, allowing easy access to the said bolts for the purposes of maintaining the panel, dismantling laminar element -1-after use one or more times in construction, replacing it by a new laminar element, or for other tasks. It should also be borne in mind that the fact that the bolts are accessible from the rear face of the shuttering panel doubly eases the work of dismantling, because the fouling brought about by pouring of the concrete is very much reduced on this side.
  • a top plug -44- seals off the column comprising doubly stepped internal plate -37- and the walls of beam -3-directly opposite the same.
  • Figure 10 shows the arrangement of a clamp for coupling two shuttering panels by their lateral edges, only one of these corresponding to beam -3- being shown in Figures 13 and 14 .
  • the clamp fixes a panel to the adjacent panel by bringing together its jaws on the stepped internal plates -37- incorporated within beams -3-.
