Definitions

  • the invention relates to a device for pouring concrete from a concrete bucket into a formwork according to the preamble of claim 1.
  • Container walls made of reinforced concrete should have a particularly good concrete quality in order to be resistant to aggressive wastewater. To do this, it is necessary that the concrete in the correct composition is poured into the formwork without demixing and that it is properly compacted. With the usual pouring of concrete into the formwork using crane buckets, the formation of a cone and thus segregation of the concrete in the formwork can hardly be avoided. With formwork heights of more than one to two meters, it is usually required that the concrete enters the formwork using a pouring pipe so that the concrete does not fall into the formwork via the reinforcement and thereby separate. Filling concrete into formwork using pouring pipes is very time-consuming.
  • the concrete must be very fluid in order to be poured into the pouring pipes. It cannot be avoided that the concrete in the formwork flows apart and thereby separates. Even when compacting the concrete, defects that can no longer be remedied very often arise. It should also be noted that the filling and compacting of the concrete is very tedious and time-consuming. When pouring concrete into formwork from a crane bucket as usual, two to three operators are used, depending on its size. Experience has shown that emptying the crane bucket into the formwork takes less time than waiting for the newly filled crane bucket to arrive again. If a corresponding layer of concrete has now been created in the formwork, the filling process is interrupted and the freshly filled concrete is compacted, which is usually done using bottle shakers. The personnel filling the concrete can also compact it.
  • WO 94/00281 describes a compacting system for concrete, which is equipped with a vibrating bottle. The filling of the concrete takes place conventionally. Depending on the size of the crane bucket, two to three operators are required for this work. such. As soon as a corresponding layer of concrete has been poured into the formwork, an operator compresses the poured concrete with the compaction system; the other operators are not deployed, so watch ⁇ .
  • This type of compacting of the concrete takes place much more slowly than in the usual compacting processes using bottle shakers by two to three operators.
  • the personnel costs can not only not be reduced by means of such a compression system, but they even increase significantly compared to the usual compression using bottle vibrators. Added to this are the higher costs for the compaction system and the additional costs for the work platform that can be driven on, so that profitability cannot be achieved with such a compaction system.
  • the inventor has now set himself the task of making the filling and compacting of the concrete flawless, effortless and very inexpensive.
  • the hopper is assigned a hopper, which is optionally provided with a vibrator; in addition, several of the vibrating bottles are arranged at intervals from one another on the deflector, which is held on the common rails along the formwork.
  • the vibrator of the funnel provided with bottom flaps is an internal vibrator.
  • the deflection device should be designed as a pulley and the number of which corresponds to that of the vibrating bottles, which are held adjustable at a distance from one another.
  • This rope pulley has a hose secured on its circumference as a supporting strand for the vibrating bottle, which is led to a reel at the other end.
  • each reel has grooves on its circumference for receiving the hose, and a hose guide for the hose should also be assigned to it.
  • there is also a method for filling and compacting concrete into a formwork for a concrete wall that is straight or curved in plan view in which concrete is poured into the concrete in several thin layers by means of a concrete bucket that can be moved along the formwork, after which the multilayer thus introduced Layer of concrete is then compacted using the vibrating bottles of a compaction system; this process is repeated until the intended amount of concrete is poured into the formwork.
  • the filled crane bucket is thus transferred to the movable concrete bucket, which experience has shown to take half a minute. One operator is sufficient for decanting and operating the mobile concrete bucket.
  • the mobile concrete bucket is emptied into the formwork, so that there is no waiting time.
  • the operation of the mobile concrete bucket is easy and effortless, since it is moved along the formwork by means of a trolley and is equipped with an external vibrator.
  • the concrete is poured into the formwork in thin layers while driving, avoiding the formation of cones - and thus the segregation of the concrete. If a corresponding layer of concrete has now arrived in the formwork, the operator who has poured the concrete into the formwork compacts the concrete in the formwork using the compaction system according to the invention, which is generally equipped with three to six vibrating bottles. Since there is already a roadway including the running gear for the mobile concrete bucket, the compaction system does not need an additional roadway.
  • FIG. 1 shows a formwork 10 made of outer and inner formwork wall 12, 13 for a concrete bed 14 which largely fills the formwork 10 and into which a vibrating bottle 16 is immersed.
  • the top of the vibrating bottle 16 extends over an extension thereof Pipe piece 17 attached to a hose 18; the hose 18, in which the power supply (which cannot be recognized) is installed in the form of lines to a vibrating motor, enables the vibrating bottles 16 to vibrate freely.
  • a compact compression system 20 can be seen, in which the vibrating bottle 16 with accessories is integrated; As a rule, three to six such vibrating bottles are provided.
  • the compression system 20 rests on a running gear 22 with a trolley 22 — a working scaffold 26 with a horizontal working platform 28 projects from the trolley 22 and a supporting scaffold 30 with ridge struts 32, from which a reel 34 for the hoses 18 rises are provided. At least one drive 36 is assigned to the reels 34. In addition, a control box 38, which contains the control for the compression system 20, hangs on the ridge struts 32. A current converter belonging to this is not recognizable.
  • the reel 34 each take up one of the hoses 18 in the winding direction X, which are guided on a deflection roller 40 from the vertical direction towards the reel.
  • Two radial safety brackets 42 are provided on the deflection roller 40 in order to hold the hose 18 in the channel-like circumference of the deflection roller 40.
  • Reel 34 and deflection rollers 40 are kept variable from each other.
  • each reel 34 is equipped with a stop safety device which interrupts the pulling up of the vibrating bottles 16 immediately if a vibrating bottle 16 should get caught while pulling up.
  • the reel 34 has circumferential grooves on its circumference, into which the hoses 18 are inserted during winding.
  • each hose 18 is guided precisely to the groove on the reel 34 intended for it by means of a hose guide.
  • FIG. 1 a concrete bucket 44 which can be moved on the formwork 10 can be seen in FIG. 1, which has a lockable slide and an external vibrator 46 on the inclined bucket bottom 45 is equipped. Both when filling the loose concrete and when compacting the filled concrete, the operator can do one or the other work from the fall-proof work platform 28.
  • the vibrating bottles 16 are tapered at the lower end 15, so that they do not collide with connecting brackets of the reinforcement when lowering into the formwork 10. So that the vibrating bottles 16 do not get caught on those connecting brackets of the reinforcement even when pulled up from the formwork 10, the mentioned pipe section 17 - with the same diameter as the vibrating bottle 16 - is attached to each vibrating bottle 16. It is provided with a tapering area 47 towards the top.
  • FIG 2 shows the upper part of an outer and inner formwork 12, 13 in section together with an adjacent working platform 28.
  • the mobile concrete bucket 44 stands on this.
  • a funnel 50 can be seen in section with flaps 54 hinged to it on the underside by hinges 52. The latter are to be kept closed by means of springs (not shown).
  • a bottle vibrator 56 can be seen in a horizontal position. If a certain amount of concrete is now introduced into the hopper 50, the two flaps 54 open equally and the concrete falls exactly vertically between the outer and inner reinforcement into the formwork 10 without it coming into contact with the reinforcement on both sides; there is no segregation. So that the concrete falls evenly from the concrete bucket 44 into the funnel 50 and from the funnel 50 into the formwork while traveling along the formwork 10, the concrete bucket 44 is equipped with that external vibrator 46 and the funnel 50 with the bottle vibrator 56.
