Definitions

  • the invention relates to a tubbing formwork for the production of tubbing according to the preamble of patent claim 1.
  • Tübbingschalungen are known, for example. from the DE 299 10 730 U1 ,
  • the tubbing formwork has a base body, on the side walls of the formwork are pivotally mounted and which is supported on a chassis assembly with wheels.
  • the shape of the tubbing produced in the tubbing formwork is determined by the geometry of the tubbing formwork. It has been observed that the geometry of a tubbing made with the tubbing formwork deviates from its desired shape if during the manufacture of this tubbings one of the impellers stands only slightly higher or lower than the others. However, deviating from the desired shape geometry of a tubbings leads to a greater mechanical stress when this tubbing is inserted into a tunnel lining with other tubbing. In addition, the effect of arranged on the surface of the tubbing seals may be impaired.
  • the invention has for its object to provide a tubbing formwork of the type mentioned, in which the geometry of the formwork while moving the tubbing formwork is more consistent than before.
  • the chassis assembly according to the invention comprises at least one suspension element which supports the main body resiliently.
  • the suspension element unevenness of a substrate on which the tubbing formwork is moved, not transmitted via the chassis assembly directly to the body, but compensated by the suspension element.
  • no torsional forces caused by a higher or lower stationary impeller act on the basic body.
  • it was precisely these torsion forces transmitted into the body that could be identified as the main reason that the side walls connected to the body experience deviations in their geometry from one another and to the body and this deviation is transmitted to the tubbing produced in the tubbing formwork.
  • each impeller is assigned its own suspension element. This is a structurally simple compensation of vertical position of each impeller possible.
  • the wheels are each connected by an independent suspension with the body.
  • At least one suspension element is formed in an advantageous embodiment of the invention by a coil spring.
  • a coil spring On the one hand, it is able to carry along the very high weight of the tubbing formwork filled with concrete and, moreover, suspension by means of a helical spring is easy to construct and therefore cost-effective to implement.
  • At least one suspension element between the main body and a trailing arm is arranged, which is associated with an impeller.
  • This embodiment has the advantage of being both stable and structurally simple and thus cost-effective to implement.
  • the spring constants of the suspension elements are advantageously smaller than the spring constant of the main body in any type of torsional deformation, ie a rotation of the body in itself, the main body can be considered to determine its spring constants as a torsion bar.
  • the chassis arrangement has at least four wheels. This embodiment ensures a high tilt stability of Tübbingschalung.
  • the body is supported on exactly three support points on the chassis assembly. All bearing points are thus always in a common plane.
  • Two impellers are preferably connected to one another via a pendulum axle, wherein the main body is supported on the pendulum axle with only one support point.
  • This embodiment is particularly stable against tilting movements of the tubbing formwork during the process. Nevertheless, no torsional forces are transmitted to the body here as well.
  • a suspension element is arranged between the base body and the pendulum axis, for example in the form of an elastic intermediate layer.
  • one or more impellers may also be associated with further suspension elements.
  • the chassis assembly on exactly three wheels.
  • the base body is always supported by exactly three support points with the already mentioned advantages over the chassis assembly.
  • the support points are formed by the axes of the wheels.
  • the wheels are advantageously offset in the direction of travel in each case in a separate track continuously offset from one another.
  • two wheels are running in the direction of travel in a common track and the third impeller offset this arranged in a further track running.
  • the top of the body forms in an advantageous embodiment of the invention either itself the bottom of the tubbing formwork or it carries such a floor. In both cases, it is achieved that the bottom of the tubbing formwork also remains free from distortions due to torsion of the body.
  • Fig. 1 and 2 schematically show a first embodiment of a tubbing formwork according to the invention 2.
  • the tubbing formwork 2 has a base body 4, on the side walls 6 of the tubbing formwork are pivotally mounted around joints 8.
  • An upper side of the main body 4 forms a bottom 10 of the tubbing formwork 2, whose position in Fig. 1 is concealed by the front side wall 6, but indicated by reference numeral 10.
  • the main body 4 is supported on a chassis assembly 12.
  • the chassis assembly 12 has wheels 14a, 14b, 14c, 14d, on which the tubbing formwork is movable.
  • the wheels 14a, 14b, 14c, 14d are formed by rail wheels, which can run on tracks, not shown in the figures, of a circulation track.
  • the chassis assembly 12 has suspension elements 15 which support the main body 4 resiliently.
  • Each impeller 14a, 14b, 14c, 14d is In the embodiment, a separate suspension element 15 in the form of a coil spring 15 assigned.
  • the wheels 14a, 14b, 14c, 14d are connected via an independent suspension with the base body 4.
  • the suspension elements 15 are arranged between the base body 4 and in each case one impeller 14a, 14b, 14c, 14d associated trailing arms 18.
  • Fig. 3 to 5 show a further embodiment of a Tübbingschalung invention with only three wheels 14a, 14b, 14c, which are connected via these respective associated individual axes 16a, 16b, 16c with the base body 4.
  • the wheels 14a, 14b, 14c are arranged in the direction of travel in each case in a separate lane continuously offset from one another.
  • the three tracks are illustrated by dashed lines 20a, 20b, 20c.
  • the main body 4 is in the embodiment in Fig. 3 to 5 supported on the landing gear assembly 12 via exactly three bearing points 22a, 22b, 22c.
  • the support points 22a, 22b, 22c are formed by the connection of the individual axes 16a, 16b, 16c to the wheels 14a, 14b, 14c.
  • the approximate positions of the bearing points 22a, 22b, 22c are indicated by numbered arrows only, without indicating their exact position.
  • the suspension 15 of the landing gear assembly 12 is in Fig. 3 to 5 not shown. Again, however, all or only individual wheels 14a, 14b, 14c suspension elements 15 are assigned.
  • Fig. 6 and 7 show a further embodiment of the tubbing formwork 2 according to the invention, wherein the chassis assembly 12 four wheels 14a, 14b, 14d, 14e of which two wheels 14 d, 14 e are connected to each other via a pendulum axis 24.
  • the rear wheel 14b is in Fig. 6 obscured by the front wheel 14a.
  • the main body 4 is supported on the pendulum axis 24 with only one support point 22d and also on the two further bearing points 22a, 22b of the individual axes 16a, 16b with the wheels 14a, 14b.
  • the base body 4 is thus supported relative to the chassis assembly 12 on exactly three support points 22a, 22b, 22d.
  • the approximate position of the support points 22a, 22b, 22d can be indicated only by corresponding arrows, without marking their exact location.
  • the pendulum axis 24 is sprung relative to the base body 4 by a suspension element 15, which is formed in the embodiment of an elastic intermediate layer in the form of a rubber boot.
  • all or only individual wheels 14a, 14b, 14d, 14e further suspension elements 15 may be assigned in addition, in Fig. 6 and 7 but not shown.
