Definitions

  • the invention relates to a formwork which can be moved further along the processing direction during the application of a setable layer, such as is used for example in concreting work, in particular on tunnel walls.
  • Such roll formwork is known in principle from DE-PS 35 33 476 by the same applicant.
  • a device for spraying a setting-capable mixture of binder, additive and a liquid is disclosed.
  • the mixture to be applied is sprayed onto the wall by means of a spray nozzle directed towards the wall.
  • a spray nozzle directed towards the wall.
  • the above-mentioned one is particularly suitable for this.
  • Patent description described roll formwork, which is moved over the sprayed mixture in the manner of a caterpillar vehicle. Between two roller-like deflection elements, a so-called formwork skin is stretched on the surface of the layer to be supported, which, if necessary, in cooperation with a support plate arranged on the underside of the formwork skin, is able to adequately support the sprayed-on layer.
  • the roll formwork disclosed in DE-PS 35 33 476 has some major disadvantages.
  • the use of an elastic formlining, in particular made of rubber, cannot rule out that the surface of the sprayed-on layer is damaged by the absorbent action of the formwork facing.
  • a slip can also occur between the formwork skin and the surface of the applied layer, which leads to a further impairment of the surface smoothness of the layer to be applied.
  • the deflection elements are supported on both sides. A change of the formlining is therefore only possible after a long disassembly of the roller formwork head and practically impossible during ongoing concreting work.
  • no side support of the sprayed-on layer is provided, so that the sprayed-on mixture can escape laterally.
  • the present invention is therefore based on the object of providing a support device which is based on the known roll formwork and does not have the disadvantages shown.
  • a formwork skin made of a non-elastic material with a smooth surface such as. B. Teflon or a metal tape use.
  • the use of these non-stretchable, smooth materials for the formwork skin prevents the surface quality of the layer to be applied from being impaired.
  • these non-elastic materials it cannot be assumed that due to the static friction between the formwork skin and the deflection elements, sufficient force transmission from the deflection elements to the formwork skin when driving the deflection elements can be achieved, as is the case when elastic materials are used for the formwork skin , such as B. rubber, is the case.
  • guide elements are arranged on the side of the formwork skin facing away from the layer to be applied, which engage in suitable counterparts provided on the deflection elements.
  • Teflon films are commercially available as thin adhesive films. These Teflon foils or Teflon tapes can advantageously on a tensile carrier material, for. B. steel, according to claim 3 are applied. Furthermore, it is conceivable to glue such Teflon tapes, which are commercially available in limited lengths, without joints and offset from one another, or to connect them in any other way.
  • a support element on the side of the formwork skin facing away from the layer to be applied.
  • the support element can also have suitable elements on the surface adjacent to the formlining, in which the Intervene in the guide elements of the formlining so that additional guidance of the formlining is guaranteed.
  • the support device may have a side support according to claim 8, in order to prevent the applied ready-to-mix mixture from escaping laterally after application and before substantial consolidation.
  • the side support can be flexibly mounted and by means of a pressing device, for. B. a spring, are pressed elastically against the wall so that the side support can adapt flexibly to the unevenness of the wall during the advancing movement of the rolling formwork.
  • the side support can be formed by one or more rotatably mounted disks that roll along the wall.
  • the side support can be suspended using a spring-loaded telescopic or pendulum arm.
  • a drive device can be provided to advance the roll formwork. It is essential that the drive device only transmits such torque to the deflection elements that slippage between the formwork skin and the applied layer is effectively prevented.
  • An electric motor with adjustable torque in particular a squirrel-cage rotor motor with phase control (winder motor) according to claim 13 can be used as the drive device.
  • the formwork skin can be designed as an endless belt that runs around both deflection elements. It is also conceivable to unwind the formlining from an angled drum during the advance of the roll formwork, to guide the deflecting elements around and finally to wind it up on a winding drum. Here, the unwinding and winding drums can simultaneously act as deflection elements.
  • a one-sided mounting of the rotatable elements according to claim 17 enables a quick change of the formwork skin.
  • the rolling formwork can be guided along a guide frame, the propulsion movement along the guide frame being able to be used to drive the deflection elements.
  • FIG. 1A shows a side view of a roll formwork, the formwork skin 7 of which is an endless belt that runs around the wedge-shaped deflection elements 6. It is advantageous to form the formwork skin 7 from a smooth, non-elastic material in order to avoid damaging influences of the formwork skin on the surface properties of the layer to be applied. However, in this case the force transmission from the deflection elements 6 to the formwork skin 7 cannot take place by means of friction, as is customary in the case of roll formwork with elastic formwork skins.
  • the formwork skin 7 is provided according to the invention on the side facing the deflection elements 6 with guide elements 27 which engage in corresponding recesses in the deflection elements.
  • An efficient lateral guidance (centering) of the formwork skin 7 results if the deflection elements 6, as shown in the top view (FIG. 1B), have a groove 29 into which the rivet-shaped guide elements 27 of the formwork skin engage.
  • the support surface 5 of the formlining 7 on the underside by means of a support element 9 that z. B. can be designed as a suitably shaped steel plate, in addition to support.
  • the guide element 9 can be one or more Have guide grooves 28 which receive the rivet-shaped guide elements 27 of the formlining 7.
  • FIG. 2 shows a side view of a first exemplary embodiment of a roll formwork with a lateral support device 31-33, which is referred to below as side formwork.
  • the pressure line 3 By means of the pressure line 3, the ready-to-apply mixture which is to be sprayed onto the wall 2 is brought to the spray nozzle 20.
  • other methods for applying the layer 1 to the wall 2 using the support device according to the invention are also conceivable.
  • Fig. 2 shows the roll formwork described with reference to Fig. 1 with a side formwork, which consists of a rotatably mounted disc 31 which is attached to a spring-loaded pendulum arm 33.
  • the spring-mounted pendulum arm 33 presses the disk 31 against the wall 2 in such a way that it rolls along the wall 2 and can follow the unevenness of the wall 2.
  • the side formwork can have a side sliding formwork 32.
  • the mixture which generally consists of a binder, an additive and a liquid, is injected through the spray nozzle 20 in the front area of the roller shuttering.
  • the setting-capable mixture hardens to such an extent that it is self-supporting at the rear end of the roll formwork.
  • the use of the roll formwork according to the invention can be used advantageously in particular when lining tunnel walls.
  • the rolling formwork moves in a circular or spiral around the tunnel wall.
  • Fig. 3 shows a roll formwork according to the invention with a second embodiment of a side formwork.
  • the two overlapping disks 31 1 and 31 2 are connected either directly or via a pendulum arm 33 to a telescopic arm 34.
  • the telescopic arm and / or the pendulum arm cause the discs 31 1 and 31 2 to be pressed elastically against the wall 2.
  • An additional sliding formwork can be dispensed with in this exemplary embodiment.
  • the elastically mounted washers 31 have the advantage of being able to roll over these reinforcement mats 22 and nevertheless being able to largely close the gap between the mats and the wall by reaching into the fields of the reinforcement mats.
  • the roll formwork according to the invention can be guided along a guide frame 23.
  • the connecting beam 15 of a supporting structure 13, which connects the two deflecting elements 6 to one another, is connected to the guide frame 23 via a supporting arm 16 and via a movement drive 8 which effects the advance of the rolling shuttering along the direction of the arrow 17.
  • the guide frame is advantageously to be designed according to the tunnel profile.
  • the rolling formwork also has a movement drive 25 which drives the deflection elements 6.
  • the movement drives 8 and 25 must be synchronized with one another.
  • z. B a torque-adjustable electric motor, in particular a short-circuit rotor motor with phase control (winder motor).
  • the torque is to be limited in such a way that the static friction between the formlining 7 and the layer 1 to be applied is not overcome, and consequently slippage between the formwork 7 and the layer 1 to be applied is reliably prevented.
  • formlining there are very suitable materials as formlining, but they cannot be welded or glued. This is especially true for Teflon tapes.
  • a finite formwork skin In order to be able to use these non-weldable or bondable materials as formwork skins 7, a finite formwork skin must be used.
  • the deflection elements 6 can be designed such that they serve as winding or unwinding drums 26.
