Definitions

  • the invention relates to a formwork for the production of precast concrete parts, with a base body which carries a shuttering floor, with side elements and with a closure arrangement, for transferring at least one side member from an open position to a closed position.
  • Such formwork serve, for example, for the production of tubbing made of concrete.
  • the formwork has a formwork floor and four side elements, which are each secured from an open position to a closed position pivotally mounted on the base body. In the closed position form the side elements together with the formwork floor a side and bottom closed formwork, can be poured into the liquid concrete. After solidification of the precast concrete side elements are moved from the closed position to the open position in which the precast concrete part is removed from the formwork.
  • the closure arrangement of the formwork consists of screws, which are rotated through the side elements in arranged in the main body thread and thereby each lead the side elements in the direction of the body until the closed position is reached.
  • Per side element usually two or three fittings are provided.
  • the geometry of the manufactured precast element is influenced by how uniformly the individual fittings are tightened.
  • An inaccurate geometry for example, a tubbing as precast concrete part leads to a greater mechanical stress of the tubbing, if it is integrated as a component in a tunnel lining.
  • the sealing properties of a seal applied to or on the tubbing may be affected by inaccurate geometry.
  • the turning and subsequent release of the screwing of the formwork is time-consuming.
  • the invention has for its object to provide a formwork of the type mentioned, in which the aforementioned disadvantages are reduced.
  • the closure assembly comprises at least one spring element, which is arranged kraftbeauffd the at least one side member in its closed position in the direction of body.
  • the at least one side element is not pressed in its closed position via a rigid element to the shuttering floor, but via a resilient spring element.
  • the spring element forms a mechanical buffer, by which the pressing force of the at least one side member to the shuttering floor in the closed position over a larger range of further actuation of the shutter assembly is much less progressively less than would be the case without spring element.
  • the spring element is preferably formed by a plate spring, a coil spring, a torsion spring or an air spring.
  • the closure arrangement has at least one actuating element which receives a force introduced from outside the formwork for transferring the at least one side element from the open position to the closed position and indirectly transfers it to the at least one side element.
  • the spring element is preferably arranged between the actuating element and the at least one side element.
  • the bracing device has a side element bolt with a bore through which the actuator is guided.
  • the side member bolt is pivotally connected about its longitudinal axis with the at least one side member.
  • the side element bolt is mounted in the at least one side wall itself and so anchored that a displacement of the longitudinal axis of the side member pin relative to the at least one side member is completely or at least limited to a slight remaining range of motion.
  • the spring element is positioned directly or indirectly between the side member and a stop arranged on the actuator.
  • the tensioning device has a set screw with a screw head, a screw shaft and a screw thread arranged thereon.
  • the actuating element of the screw head and the actuator is formed by the screw shaft.
  • the screw thread engages in a counter thread connected to the main body.
  • the screw head is screwed into or out of the mating thread, the length of the screw shaft not in the counter thread determining the position of the at least one side element.
  • the screw head engages directly or indirectly on at least one side element.
  • the stop is particularly preferably also formed by the nut. This embodiment is inexpensive to produce and yet ensures a safe and low-maintenance design of the bracing.
  • the bracing device has a main body bolt with a bore, in which the counter thread of the adjusting screw is arranged.
  • the main body bolt is pivotally connected about its longitudinal axis with the base body. This ensures that the screw is not deformed when screwing or unscrewing into the mating thread.
  • the main body bolt is preferably stored in the body itself such that the position of the longitudinal axis of the body bolt relative to the body is always consistent or at least only due to a small range of motion for rotation of the body bolt is variable about its longitudinal axis.
  • the bracing device has a limiting device arranged in the screw shank, the positioning of which limits a screwing-in of the screw shank into the main body bolt.
  • the positioning of the limiting lock determines the maximum force acting on the at least one side element spring force in the closed position of the side wall.
  • the limiting barrier is particularly preferably arranged between the side element bolt and the main body bolt.
  • the bracing device has an opening lock, which is arranged on the screw head opposite end of the screw shaft and limits unscrewing of the screw shaft from the main body bolt.
  • the positioning of the opening lock defines the maximum possible opening position of the at least one side element.
  • the limiting barrier and / or the opening blocking are each formed by a nut and a counter nut associated therewith.
  • the bracing device has a tension element which is arranged between actuator and actuating element.
  • the tension member when the tension member is rigid, it serves not only to pull the actuator in one direction but also to push the actuator in the other direction. If, for example, the at least one side element is moved by pulling on the actuator via the tension element from the opening position in the direction of the closed position, then the rigidly formed tension element can again move the at least one side wall from the closed position into the open position to press.
  • the tension element works at the same time as a pressure element.
  • the actuator preferably has a pressure stop which acts directly on the side element bolt or the side element via the tension element.
  • the closure assembly comprises a plurality of bracing, the tension elements are force-connected to a common actuator. Particularly preferably, all tension elements end in a common actuating element.
  • the spring element can advantageously be arranged alternatively to the described positioning or, in addition thereto, between the actuating element and one or more tension elements. This makes it possible to apply force to several tension elements and about them actuators with only one spring element. The maintenance of the formwork is simplified.
  • the at least one side element comprises a shuttering wall and a wall bracket carrying it, wherein the shuttering wall is connected via the wall bracket pivotally about a pivot axis with the base body.
  • the closure assembly is arranged outside of a formwork wall and the formwork floor partially limited formwork.
  • the side member bolt is connected to the wall bracket. This embodiment ensures that the closure arrangement does not undesirably affect the shape of the formwork.
  • Fig. 1 and 2 describe a first and 3 and 4 a further embodiment of a formwork according to the invention 2.
  • the formwork 2 each has a base body 4, which carries a shuttering bottom 6.
  • Side elements 8 are pivotally connected about a pivot axis 10 with the base body 4.
  • FIG. 1 the left side member 8 is shown in an open position 12 and the right side member 8 in a closed position 14.
  • the closed position 14 of the side elements 8 these form together with the shuttering floor 6 a laterally closed and closed form 16, in which liquid concrete can be poured. After solidification of the concrete, the side elements 8 are moved to their opening position 12, so that the manufactured precast concrete from the formwork 2 can be easily removed.
  • the formwork 2 has a closure arrangement 18, which comprises two spring elements 20 in the present case.
  • the spring elements 20 are arranged in such a way that they force the side elements 8 in their closed position 14 in the direction of the base body 4.
  • the spring force stored in the spring elements 20 is greater in the closed position 14 of the side members 8 than in the open position 12th
  • the closure assembly 18 has in the present case two actuators 22, each serving a Verspann worn 24 of the closure assembly 18.
  • the bracing device 24 each includes an actuator 26, at the end of a stop 28 is positioned and connected to the actuator 26.
  • the bracing device 24 also has in each case a side element pin 30 with a bore 32 through which the actuator 26 is guided.
  • the side member pin 30 is pivotally connected about the longitudinal axis 34 with the side member 8.
  • a transfer of the side members 8 of the closed position 14 in the opening position 12 of the side member pin is pivoted about the longitudinal axis 34, as by changing the positioning of the longitudinal axes 36a, 36b of the actuators 26 in Fig. 1 is illustrated.
  • the clamping device 24 each have an adjusting screw 38, wherein the tensioning device associated with the actuating element 22 and the stop 28 of the screw head and the tensioning device 24 associated actuator 26 is formed by the screw shaft.
  • a screw thread 40 is arranged, which engages in a connected to the base body 4 mating thread 42.
  • Each bracing device 24 in this case comprises a main body bolt 44 with a bore 46 in which the mating thread 42 of the adjusting screw 38 is arranged.
  • the main body bolt 44 is pivotally connected about its longitudinal axis 48 with the base body 4.
  • the bracing device 24 in each case has a limiting lock 50 arranged on the screw shank 26, whose positioning limits a screwing in of the screw shank 26 into the main body bolt 44.
  • the limiting barrier 50 is formed by a screw nut 50a turned on the screw thread 40 and a counter nut 50b assigned thereto. In the closed position 14, the limit stop 50 abuts against the main body bolt 44 and thereby prevents further screwing in of the screw shank 26 into the main body bolt 44.
  • the bracing device 24 also has in each case an opening lock 52, which is arranged on the screw head 22 opposite end of the screw shaft 26 and in the exemplary embodiment is also formed by a screwed onto the screw thread 40 nut 52a and one of these associated lock nut 52b.
  • the opening lock 52 limits further unscrewing of the screw shaft 26 from the mating thread 42, in which the opening lock 52 strikes the base body bolt 44 in the course of unscrewing.
  • FIG. 3 and 4 show a further formwork 2 according to the invention, which basically corresponds to the embodiment described above, but whose closure assembly 18 is modified.
  • the bracing devices 24 each have a tension element 54, which is arranged between the actuator 26 and the actuating element 22 is.
  • the tension elements 54 of the bracing devices 24 of two opposing side parts 8 of the formwork 2 terminate at a common actuating element 22 and are in each case force-connected with this.
  • Fig. 3 By operating the actuating element 22 in the form of a rotation about the axis of rotation 56, the side elements 8 are indirectly in the closed position 14 via the tension elements 54 and spring elements 20, on which the tension elements 54 each act convicted in Fig. 4 is shown.
  • the tension members 54 are rigidly formed in the embodiment, so that this movement process can also be performed vice versa and the side members 8 can be pressed by operating the actuator 22 via the tension members 54 from the closed position 14 of the side members 8 in the open position 12.
  • a pressure stop 58 is arranged on the actuator 26, which acts on the side member pin 30 in a pressing movement of the tension element 54.
  • the side elements 8 shown in the figures each comprise a shuttering wall 60 and a wall bracket 62 holding this shuttering wall 60.
  • the shuttering form 16 is partially bounded on the underside by the shuttering bottom 6 and on the sides by the shuttering walls 60.
