Device for the vertical adjustment of several internal vibrators for concrete or the like in an upright position

Cladding

The innovation relates to a device for the vertical adjustment of several internal vibrators for concrete or the like in an upright casing.

As is well known, vibrators are used to create concrete walls, prefabricated parts, etc. to the to achieve the desired compaction of the concrete or the mass to be introduced into the formwork.

A relatively simple way of compacting the concrete to be introduced into the formwork results from the use of so-called external vibrators, which are attached to the outside of the casing. The main drawbacks These known vibrators are on the one hand in the uncontrollable compaction work and on the other hand in the considerable noise that is caused by direct contact with the casing and itself particularly noticeable in cladding made of metal plates.

So-called internal vibrators have therefore been developed which are moved back and forth in the concrete to be compacted

and with increasing filling and compression in the casing must be pulled up accordingly. For this work, an operator is usually used, the full is busy; however, this makes the concreting process extremely costly.

A device has therefore already been developed for the vertical adjustment of several internal vibrators in an upright formwork for the production of round concrete piles. This is where a float is released from the inner wall the concrete formwork with a circular cross-section. However, if this known device in relatively long / verscnaiunge'n is used, then one is missing Longitudinal guidance. This means that neither a uniform pouring of concrete nor a uniform compaction can be achieved guaranteed.

The innovation is therefore based on the task of avoiding the deficiencies mentioned in known designs To create device of the type mentioned above, with a relatively simple structural design is used for elongated casings, with each internal vibrator being individually adjustable.

This object is achieved according to the invention in that several in a common frame outside the casing separate, drivable adjustment devices are provided, each of which is assigned to an internal vibrator and is connected to this via a consumable line and a flexible suspension, which is connected to the upper Edge of the formwork supported, displaceable deflector is performed.

In the embodiment according to the innovation, everyone can Internal vibrators can be set vertically, where-

space-saving for the adjustment devices of all internal vibrators and are arranged in a simple manner in a common frame. The monitoring of these adjustment devices can be done quite incidentally, without the need for a special operator. Because of your The deflecting devices supported on the upper edge of the formwork can be arranged so that they can be displaced the individual internal vibrators do their compression work in the most favorable areas within the casing. The deflection devices also make it possible to use the frame with the adjustment devices in the most favorable manner to be arranged next to the cladding.

The assignment of one adjusting device to an internal vibrator also allows the individual internal vibrators differently and independently of each other vertically and differently deep into the concrete or the cladding to be immersed, which is important for walls with door and penster cutouts, for example.

Significant advantages can also be seen in the fact that commercially available parts for the device according to the innovation, In particular, commercially available internal vibrators can be used and that the individual adjustment devices are only made relatively small, since they are only intended for one internal vibrator.

Further details of the innovation emerge from an exemplary embodiment described with reference to the drawing. In the very schematic drawing (with a perspective view) the device according to the innovation is used for several casings lined up next to one another, for example of prefabricated parts.

The device according to the innovation is used for vertical adjustment (see double arrows a) of several internal vibrators 1, I ', I ¹ ' for concrete in an upright formwork.

Each internal vibrator 1, 1 ', I ¹¹ is assigned a separate adjusting device 3) 3' or 3 ^tr , each of which can be driven individually. These adjusting devices 3>3'j 3 ^IT are designed in the manner of a cable drum which is provided with a single motor; this single motor can expediently be built into the drum or attached to the side of the drum. All adjustment means 3, 3 'and 3', ¹ are provided in a common frame 4 outside the casing. A favorable and space-saving arrangement results when the adjusting devices 3, 3 '>3''are mounted essentially one above the other in the frame 4.

Each vibrator 1, 1 ', I ^1' is with its associated adjusting device 3, 3 and 3 ^{T 11} is connected via a flexible suspension 5, 5'j 5 ^'1, over a supported on the upper edge 2a of the casing 2 redirector 6, 6 'or 6''is performed. These deflecting devices can be offset in the longitudinal direction on the upper edge 2a, so that the most favorable position for the associated internal vibrator can be set. The latter can also be achieved in that the deflecting devices 6, 6 ', 6' ¹ contain deflecting rollers 7, 7 'and 7 ¹¹ , which are mounted on axles 8, 8', which extend transversely to the casing 2 and are supported on the upper casing edge 2a. 8 ' ¹ and are axially displaceable to these axes.

In the case of the flexible suspension 5, 5 'or 5 ¹¹ from which the internal vibrators I ₅ 1' or l ^tT hang, it can be useful

be a kind of rope, the ζ. B. with air vibrators by a more flexible. Air hose and, in the case of electric vibrators, can be formed by reinforced electric cables. The ropes 5 »5 ', 5" are wound up in the desired manner on the associated drums 3 »3' or 3" during the compression work of the internal vibrators and are thus pulled up within the casing 2 or the concrete 9 therein. Before the start of the concreting process in the formwork 2, the ropes 5, 5 ', 5' ^{1 are} unwound from the drums so that the internal vibrators 1, 1 'j 1' ¹ are lowered vertically downwards. For the guidance of these ropes, further suitable deflection elements 10, 10 ', 10 "are provided in the frame * 1.

Together with ropes 5, 5 \ 5 ^I! are from the adjustment devices 3, 3 ', 3' ¹ consumable lines, not shown in detail, to the individual internal vibrators 1, 1 ', I ¹ '. Since commercially available designs can be used as internal vibrators, the consumable lines - depending on the internal vibrator design - can be electrical cables or compressed air hoses (see above). The consumable lines can be incorporated into the associated rope 5, 5 'or 5 ¹ '. In this case, each consumable line is connected to an external consumable feed 11, II ¹ , II ' ¹ via the interior of the associated drum 3, 3 ′ or 3 ″.

So that the device according to the innovation can work largely unsupervised during concreting, each adjustment device 3 _S 3 ^f , 3 "is connected to a device - not shown - for automatic control of the vertical adjustment of the associated internal vibrator.

As has already been mentioned above, the device illustrated in the drawing is intended for several casings lined up 2 are used one after the other. For this reason, in addition to the cladding 2

Runways 12 are arranged on which the frame 4 with the help of rollers or wheels can be moved in the direction of the double arrow b, this method is carried out approximately parallel to the upright cladding 2. There is thus the possibility of using the device according to the invention to use in several claddings 2 one after the other and without significant interruption, so that for example finished components can be manufactured on an ongoing basis.

The device according to the innovation described with reference to the drawing can be used without special labor costs (by a additional operator) and use it in a space-saving manner for various types of concreting, with the concreting work with relatively little noise pollution (due to the internal vibrators) and extremely controlled (in the cheapest. Eijisatz areas) can take place. Apart from the simple structure of the described Device, the manufacturing costs can still be kept relatively low that predominantly Commercially available parts can be used.

Finally it should be mentioned that the innovation according to Device can be used not only with narrow and long formwork or prefabricated parts, but with the same can also be used successfully on construction sites.
