Definitions

  • the invention relates to a surface formwork from inside and External formwork for creating an annular concrete wall with stiffening elements and with at least one Movable concrete bucket.
  • Such a surface formwork is disclosed in the DE document 93 09 954 U1.
  • the concrete bucket used to fill the concrete is with a - containing a drive - Chassis connected and is on both sides by means of wheels of the formwork room arranged rails.
  • the pair of rails can also be placed together inside the formwork be provided; then the one rail is polygonal as well as angle-adjustable formwork girders, which in turn on vertical profiles, as stiffening elements serve the internal formwork, be fixed; the other rail lies on a protruding from the inner formwork Working platform.
  • the concrete is poured into the large-area formwork usually using a concrete pump or a crane bucket.
  • Concreting with concrete pumps is expensive, too the permissible dumping heights often exceeded what to poor quality concrete.
  • the filling of Concrete using crane buckets is also very labor intensive.
  • the concrete often slips out of the crane bucket, i.e. H. in several servings, which is particularly important for larger concrete drop heights to segregation and thus to poor concrete quality can lead.
  • the inventor has the Task given a bracing for one in diameter adjustable large-area formwork for cylindrical concrete structures to develop, with which the internal formwork as well as the External formwork can be braced. Furthermore, the Additional functions that can be handled easily can take over.
  • both the outer formwork and the Internal formwork several stiffening rings from ring segments assigned whose curvatures correspond to the diameter of the surface formwork are adapted and at least of which in the installed position upper stiffening ring of the inner formwork Offers rail for the concrete bucket.
  • the bracing for the outer formwork is therefore carried out by means of the - adapted to the respective diameter of the surface formwork - Stiffening rings that act as a rail for a Work platform movable in the circumferential direction are, and for stiffening the inner formwork are also - Adapted to the respective diameter of the surface formwork - Provided stiffening rings that at least partly as a running track for a circumferential direction Concrete buckets are designed. This with external vibrator and is a concrete bucket with an adjustable slide can be moved with an electrically driven chassis educated.
  • three formwork rings 16 are mounted on one another.
  • the two lower formwork rings 16 are each provided with two stiffening rings 18 , 18a, one of which is attached in the lower area of the respective formwork ring 16 and the other in the upper area of the respective formwork ring 16.
  • the stiffening rings 18 of the outer formwork 12 and the stiffening rings 18 a of the inner formwork 14 are releasably connected to the formwork rings 16 by means of hooks 20.
  • the stacked formwork rings 16 are detachably connected to one another in a known manner by means of screws or clamp closures, so that one stiffening ring 18, 18a, which is detachably arranged in the upper region of the formwork ring 16, is sufficient for the upper formwork rings 16.
  • One of the stiffening rings 18 on the free flange 19 is by means of at least two rope pulley-like rollers a working platform 24 can be moved in the circumferential direction.
  • This work platform 24 is supported on one below it arranged stiffening ring 18 via two support rollers 26 whose axes are arranged vertically.
  • the work platform 24 is provided with a guardrail 28 as well with a safety device 30, which a crash the working platform 24 prevented. If necessary, the Working platform 24 by means of an unrecognizable construction crane set higher or lower.
  • the Stiffening rings 18a of the inner formwork 14 are made of the same profiles as the Stiffening rings 18 of the outer shell 12, also identical, the arrangement and the number of Stiffening rings 18 and 18 a, and their detachable attachment 20 by that hook the two upper Stiffening rings 18 a of the inner formwork 14 are each provided with a running rail 32 as a carriageway for a concrete bucket 34 which can be moved along the formwork 10.
  • the running rail 32 serves as stiffening for the stiffening ring 18a in the vertical direction in order to avoid bending when pouring concrete; the running rail 32 is therefore also firmly connected to the stiffening ring 18 a , preferably welded.
  • the concrete bucket 34 is guided on at least two pulley-like rollers 22 a on the running machine 32, one of the rollers 22 a being connected to a gear motor 36 to form a running gear. Furthermore, the concrete bucket 34 is equipped with an external vibrator 38 and an adjustable slide (not shown).
  • the concrete bucket 34 is supported with profiles 40 by a support arm 42 on a truss tower 44 arranged vertically in the center of the circular wall to be built - rotatable about a bolt 46.
  • the power supply is expediently carried out via a power cable which is guided in the vicinity of the lattice tower 44 from the floor B to the profiles 40 and from there to the concrete bucket 34.
  • Fig. 2 is executed a top viewed section of the large-area formwork 10 are attached to a stiffening ring 18 of the outer formwork 12 mounted working platform 24 and a section of the inner formwork 14 with mounted concrete bucket 34. Stiffening rings 18 and 18 a recognizable as ring segments.
  • FIG. 3 An embodiment of how the ring segments of the stiffening rings 18 , 18 a are detachably connected to one another is illustrated in FIG. 3.
  • three plates 50 each with an elongated hole 48, are arranged one above the other.
  • the upper, visible, and the lower non-visible plate 50 are on the ring segment - on the right in FIG. 3 - is welded, and which extends between the upper and the lower plate 50, the middle plate 50 a, is at the ring segment - on the left in Figure 3 - welded.
  • the ring segments can be quickly and easily connected and detached.
  • the concrete is from Crane buckets filled in the concrete bucket 34, which is less than takes a minute.
  • the operator empties for the concrete bucket 34th the concrete during a tour around the formwork 10 uniformly low dumping heights in the formwork interior out.
