Machine for the production of concrete slabs.

The invention relates to a machine for the production of 3etonplatten and with a pivoting about a horizontal axis' form, which after filling unl compaction of the concrete with a vibrator that can be moved over the mold can be turned, so there !? the concrete slab slide out of the mold and can be transported away on a tray above the mold before turning.

The vibrator, which is not in the 'mold and turn of the same may stand over the form, should be able to be easily moved into its working position over the form, and it was suggested earlier to have it together with the engine to generate the vibrations on a vibrating table, which is on rails on the top of a frame, which also supports the shape during concreting, can be moved. The mobile vibrating table is easy to use provided with the operator on the opposite side Side of the form is to pull the vibrating table to itself until the vibrating organs are above the concrete in the Stand in the same way as it is supposed to push it back after the vibrator has been used. This operation is quite uncomfortable and tiring for the operator.

The purpose of the invention is to produce a concrete slab machine of the type mentioned, with a vibrator, which is more efficient and is faster and easier to use than the known

Vibrators, and this has been achieved according to the invention by that the vibrator of the machine is mounted such that it can pivot about a vertical axis that it is from a position next to the mold can be pivoted about the same and that it has a vertically displaceable pressure plate in addition to known vibrating elements has, of such dimensions and so attached that you can press mainly the whole of them by swiveling the vibrator Can bring concrete surface inside the form.

When the operator has poured concrete into the mold, he no longer needs to stretch over it to close the vibrator but can easily grab the jogger that has been swiveled out to the side of the mold and turn it into the working position, where it works effectively and quickly because, in addition to vibrating the concrete, it also moves it with the help of the vertically displaceable Compressed pressure plate. The vibrator can be operated particularly easily if, as is the case in a preferred embodiment, it is provided with a handle, the operating elements for lowering the pressure plate pneumatically or hydraulically and for starting the vibrating elements, which in a known manner can comprise an eccentric shaft driven by an electric motor via a drive belt.

The machine according to the invention may also be provided with an auxiliary mechanism having a lift cylinder for lifting and turning the mold, and this mechanism can also easily be controlled by Bedi enungsorganen on the handle for pivoting the vibrator.

The invention is explained in more detail below with reference to the drawing. It shows

Fig. 1 is a side view of an embodiment of the concrete slab machine according to the invention and

FIG. 2 shows a plan view of the machine according to FIG. 1 on a smaller scale and with the vibrator in the swiveled-out position.

The machine shown has a mold 1 which is rotatably mounted with an axis 2 in a mold suspension 5 so that they can be pivoted over a removal table 6. On the Axis 2, a pair of plate holders 3 are rotatably mounted, which are provided with handles so that they can have a " The tray (not shown) attached to the top of the mold can be pivoted, thereby creating the concrete slab the mold and the tray are held together when pivoting by the operator turning the handles of the tray 3 and at the same time to protruding handles 7 of the Takes shape. When the mold has been rotated 180 ° around the axis 2, the tray rests on the removal table 6, and When the handles of the plate holder are released, the support plate, concrete plate and removal table 6 slide down until the Concrete slab is guided out of the form, which is held in place by stops 4 on the same on protruding horns on the Form suspension 5 run up. The take-off table 6 can be balanced with a counterweight, or it can be of one with a Pedal operated hydraulic or pneumatic lifting and lowering mechanism 16 are moved.

At the end of the frame 12 of the machine facing away from the mold 1 there is attached a column 17 on which a vibrator 8 is rotatably mounted so that it can move from the pivoted-out position shown in FIG. 2 over the mold to that shown in FIG Position can be pivoted, where a pressure plate 9 can be pressed against the concrete in the form and can be set in vibrating motion with the help of vibrating elements in the form of a shaft with an eccentric, which is driven by an electric motor 11 suspended from the vibrator. If the width of the printing plate 9 is smaller than the width of the mold, the vibrator 8 is swung from side to side, so that the pressure plate covers the whole ⁿ etonoberfläche.

Dor vibrator is at its free end with a handle 13 provided with which it can be easily pivoted in and out of the working position, and this handle carries a panel 14 with controls for lowering and lifting the pressure plate 9, which is preferably done pneumatically or hydraulically, and

for starting and stopping the vibrator motor 11. The panel 1 * 1 · also has in the embodiment shown an operating member for controlling an auxiliary mechanism which comprises a lifting cylinder 15, one end of which is rotatably connected to an arm rigidly attached to the mold 1, see above that this mechanism can help lift and turn the mold. It goes without saying that the machine according to the invention can be operated without great manual effort and without large arm movements, because the vibrator is only pivoted from one position to the side of the mold over the same and the various operating elements are to be operated in the correct order so that compacting the concrete, vibrating and turning the mold and emptying the same can take place. claims. 1.
