"Holding device for internal vibrators for compacting materials, especially concrete".

The invention relates to a holding device for internal vibrators for compacting materials, in particular Concrete.

Usually concrete is also made by hand with a large vibration depth by the individual workers with internal vibrators shaken; vibrating bottles are usually used for this.

On the one hand, this vibration method is complex, because each worker can only operate one vibrator bottle and on the other hand, the vibration process is imprecise, because once the compaction in the individual depths of the Building or even distributed over the horizontal can not be controlled or only imprecisely.

The invention is based on the object of the vibration control with at least one internal vibrator and simplify handling.

The object is achieved in that, according to the invention, the Holding device consists of a Höhenverstsllvorrichtung, which on a frame or the like, arranged and transversely is movable to the surface to be compacted.

The height adjustment device is more practical from a traverse, a rod frame, a plate or the like. However, it is also possible if only one is used Internal vibrator to attach this to a jib crane, for example; in this case the crane rope forms the height adjustment device and the boom forms the frame. That way will it is possible to shake at different depths without the need for manual handling; also takes place the transverse movement of the internal vibrator mechanically. In this context it should be mentioned that it is already known is to combine several vibrating bottles when compacting the concrete surface in road construction and in one To attach trolleys; the vibrators are common with the car along ;: pulled the concrete surface; a lowering and thus there was also a shaking at different depths not possible with this known device.

It has therefore proven to be particularly useful that the Holding device carries at least two internal vibrators. This makes it possible not only to manual loading of the worker and to operate at least two internal vibrators at the same time, but also through the Height adjustment to a vibration in different depths simultaneously over an intended period of time steer. The compaction of concrete, for example, is so "4t!" More accurate adjustable and controllable, as not only the vibration point and depth remain unchanged without difficulty.

hold, but also adhered to the jogging time more precisely can be.

Furthermore, it is possible that at a distance from the height adjustment device a traverse, a rod frame, a Plate or the like. is provided, which is also adjustable in height with respect to the Höhenverstellvorvichtung is; To adjust the distance between the height adjustment device and the traverse or the like, a pulley system or the like. be provided.

Suitably there is the traverse or the like. from a self-contained -tabgeriist or the like, at the respective corners of a suspension device for the internal vibrator and / or for connecting chains or the like is provided for reading part; the rods of the rod frame p or the like. can be articulated together; it is also possible that the individual rods between their ends each have a further joint or the like. exhibit; this transforms the basic shape of the traverse into another basic shape possible. In this embodiment it is expedient that the corner points of the rod frame are in the operative position on the opposite rods are supported.

Another modification of the invention is that with a traverse or the like. at least one measuring scale is provided for the depth position of the respective internal vibrator; the two trusses or the like. can be connected by rods that can be moved to the latter, each with a measuring scale.

In the drawing, for example, embodiments of the invention are shown. Show it:

A relatively deep concrete body 1 should be made by means of vibrating bottles, i.e. internal vibrators, are compacted. For this purpose, a possibly movable or displaceable frame 2 a holding device 3 attached. There are several hoses on this holding device H, 5 of Rüttelflascheii 6, 7 firmly attached; latter can thus be lowered into the structure 1 via the frame 2 by means of the holding device. In the event of the use of only one vibrating bottle can e.g. via a sleeve holding the hose or the like. be attached to the crane hook; the boom of the crane is used in this Case as a rack.

In the embodiment shown in Fig. 1 and Fig. 2, a second holding device 8 is also provided, whose band to the holding device 3 can be changed and in such a way that, as can be seen from FIG. 2, by reducing the distance between these two holding devices the vibrating bottles 6 and 7 not only lifted out of the building 1, but also in the same on a certain Depth · be lowered.

An embodiment of the invention, not shown, consists in that the holding device 3 is by means of deflection rollers and a cable drum can be adjusted or lowered in height via the frame 2. So Ea will

from the cable drum from the depth of the vibrating bottles;

immediately determined; the holding device 3 is in \

in this case attached to a movable gallows, for example. '

A frequently used embodiment of the invention is shown in FIG. 3, in which the holding device consists of a plate 10 which - as can be seen from FIG. K - is triangular and has rods 11 in each of its corners. These rods 11 receive a second plate 12 which is displaceable on these rods. A displacement of the plate 12 in height causes a reduction or an increase in the distance from the suspension point 13 of the device according to the invention. The suspension point is determined, for example, by the free end of a pivotable and displaceable bracket, as shown in FIGS. 1 and 4, for example.

To change the distance between the two plates 10 and 12, a roller or a pair of rollers 16 or 17 is attached to the latter by means of a frame \ k or 15; the pairs of rollers 16 and 17 are connected to one another via a cable or pulley block 18. By moving the two pairs of rollers 16, 17 relative to one another, the height between the plates 10 and 12 is determined. Because the height of the suspension point 13 cannot usually be changed, the internal vibrators 20, 21, 22 are only lowered or raised by relative adjustment of the two pairs of rollers 16, 17.

On the plate 12 guide sleeves 23 are provided in which the rods 11 are slidably mounted Guide sleeves can be used to determine the penetration depth the vibrating bottles can be used in the simplest possible way,

for example by providing special height notches on the bars. Any other measuring scale can can be used for the same purpose.

The plate 12 is by three chains 2M, 25, 26 or the like. at the Suspension point 13 suspended.

After Pig. 5 is a slide train 31 via a cable 32 connected to a cable drum, not shown, so that in this way the raising and lowering of the plate 33 with respect to the plate 3M.

The attachment of the vibrating bottles 35 and 36 or the like. he follows by metal sheets 37 which are bent over in such a way that the tubes of the vibrating bottles are held firmly in place will.

In the embodiment shown in FIG instead of the plates a rod frame is used as a holding device. The rod frame consists of the one shown Embodiment made up of three rods MO of equal length, which are each connected to one another by joints Ml. The holding device is thus indicated in a triangular shape with solid lines, with in the respective corners the chains can be attached that lead to the suspension point or, on the other hand, also attach the RütteIfläsehen can be.

Due to the articulated design of the corners of the rods Mo existing bar framework and the fact that a further joint M2 is provided in the middle of each bar the triangular basic shape of the holding device, as indicated by dashed lines, into a hexagonal one can be converted so that, for example, if necessary, six vibrating surfaces and / or hanging chains at the corners or the like. can be attached.

can on a mlttxgen plate 44 in their axial direction Slidable rods 45 find use, each to the corners of the rod scaffolding. These rods 45 can can also be used in the triangular shape.

The use of several internal vibrators at the same time enables optimal compaction with a vertically offset arrangement of the vibrating bottles. At a Use of several internal vibrators at the same time Manpower saved, so that more economical work is possible. The vibrators can be relocated to a level outside the immediate place of use, which is particularly important in confined spaces. The lifting speed can be set so that simultaneous compaction is achieved at all depths; through the Measuring scales on the guide indicators or also on the cable drum, an optical control is possible. The depth of penetration of the internal vibrator (s) into the concrete can be Be checked at any time.

It is obvious that the lifting device can also be operated hydraulically, mechanically or pneumatically can be done.
