Description

Title of the Invention Forming device

Field of application of the invention

The invention relates to a molding device, preferably for producing large-area concrete elements, with means for releasing the concrete element from the mold bottom and from inserts arranged thereon *

Characteristic of the known technical solutions For the production of large-scale concrete elements, a wide variety of shaping devices are used, such. As tilting, tilting tables, mold car and the like ·

For decalcifying the inner inserts the most diverse principles of action and aids are used. Thus, it is known that the inserts are fixedly arranged on the mold bottom and the concrete element is pressed by means arranged in the mold bottom hydraulic cylinders from the mold bottom and the inserts mounted thereon.

Furthermore, it is known that when using tilting molds or tilting tables, the concrete element together with the mold is pivoted into a vertical position. In the vertical position, the concrete element is taken over and held by a separate scaffolding, the mold and attached to the mold bottom inserts are then tilted back by means of their tilting, whereby the concrete element from the mold bottom dissolves and the inserts are pulled out of the concrete element.

Another way to remove the inserts from the concrete element is that the inserts are pulled by crane from the concrete element. In order to avoid tilting of the inserts and consequent damage to the concrete elements, it is particularly necessary when using larger Eialegeteile that these and the like to auxiliary equipment, such as traverses. have to be posted.

In order to reduce the difficulties encountered in removing the inserts from the concrete element, inserts have been developed and used, which can be moved before removal in order to then remove them from the concrete element can. Furthermore, according to DD-PS 53711 and DE-GM 7426006 Pormeinrichtungen known that apply the principle of the inclined plane in Entschalprozeß, wherein the inserts do not remain slidably arranged on the mold bottom.

All the above-described methods for removing inserts from concrete elements are currently used in the manufacture of large concrete elements, but they have the following disadvantages.

For the majority of the additional equipment used, such. As in the arrangement of a separate scaffold for receiving the concrete element or the arrangement of hydraulic Abdriickzylindern in the mold bottom, there is a significant overhead in the production and maintenance of facilities for concrete element production. In addition, the susceptibility to failure of such facilities and the production time for concrete elements, since additional work cycles, such as the execution of a separate Abdrückvorganges or striking special brackets or for pushing together the inserts or the manual knocking out the same must be provided ·

Furthermore, the time spent in the manufacture of concrete elements for the technologies in which the inserts must be released from the mold base before removal from the concrete element, as before the beginning of a new production cycle, the inserts are adjusted again to their position on the mold bottom.

Object of the invention

With the help of the inventive design of a molding device is to be achieved that no special complex Hilfsseinrich * tions must be used to remove the inserts from the concrete element · Furthermore, the cycle times for the Entschalen, the susceptibility of the molding facilities are lowered.

Explanation of the essence of the invention

The invention has as its object to provide a molding device that provides assurance in ensuring complete reliability that without the use of expensive equipment and without removing the inserts from the mold bottom removal of the inserts from the concrete element is possible. At the same time separate cycle times and manual, physically strenuous work to remove the inserts are to be eliminated.

This is essentially achieved in that on a mold bottom in the region of the concrete element two or more wedges fixed and the inserts slidably in the direction of the inclined plane of the wedges, however, are not foreseeable from the mold bottom. The wedges are preferably arranged in the upper third of the concrete element on the mold bottom.

embodiment

The invention will be further illustrated by an embodiment and described

 The accompanying drawing shows

in Fig. 2, the molding device according to the invention in

a side view shown

In the molding device according to the invention 2, two or more wedges 3 are fixedly arranged on a mold base 1, for example, a known tipping mold, preferably in the region of the upper third of a concrete element to be manufactured.

The position of the wedges 3 is considered here by the tilt axis axis. The inserts 4 are mounted on the mold base 1 that they slightly, about 20 mm, move upwards on the mold base 1, but can not be lifted off this. The latter is achieved in that the inserts 4 are provided with fastening elements 5, which have slots in which screws are arranged for fixing the inserts on the mold bottom. The possible displacement direction and size is fixed by the position and length of the slots.

The lifting of the concrete element 2 from the mold base 1 and the release from the insert 4 now takes place as follows. After the side shutters, not shown in detail in the drawing were removed to the lower formwork in a known manner, the tilting of the tilting takes place in the usual manner from the horizontal to the vertical position, as shown in the arrow direction in Fig. 2. Shortly before reaching the vertical position of the concrete element, the lower formwork 6 is pressed against abutment 7, whereby the concrete element 2 is released from the mold base 1 and pushed with the insert 4 upwards »

At the same time we * d the concrete element 2 lifted by the wedges 3 from the ground and released from the insert 4. The further removal of the concrete element 2 and its removal takes place according to the previously known technologies ·

After returning the tipping mold to its starting position, the insert 4 is pushed back to its original position and is thus adjusted without any special effort in its production position.

The inventive release of the concrete element 2 from the mold bottom and the insert 4 can be used in the manner shown above in all tiltable shapes.

The solution according to the invention can also be used in non-tiltable molds by a side mold is moved mechanically or hydraulically on the mold bottom in the direction of the wedges, whereby the effect of lifting the concrete element by means of wedges from the mold bottom and to release from the inserts, also be achieved may ·
