"Device for making a bell body for larger ones Building cells "

The invention relates to a device to produce a bell body for prefabricated garages, apartment ropes or other larger building cells with a formwork for a casting compound, in particular concrete, which consists of an extendable outer formwork and a formwork core > that of a ceiling formwork, separate retractable side formwork and between them Formwork parts arranged joint seals is composed.

In a known device of this type (UT-Grl 1 S '^'-> 719) the corner feet consist of tiiiikelprofileisen, the ceiling formwork on the side formwork and asr it the side ehal'ongen of the formwork core can xerden fixed clamping wedges solvable Zlaeh of Eerstellen of Forislings in the formwork Serden the clamping wedges solved and out of the Seitenschaltanjj ^ n even the ceiling formwork withdrawn ndttels spindles the Uinkelprofileisen remain initially ir.?. molding, be = zasan sen salt this from deis Formwork core excavated and then pulled out of the bell body produced.

This known device is limited to the production of such bell bodies which are designed completely freely on one face, so that there are no remaining nozzles to pull out the VJinkelprofileisen ir: Τέύ & £ , / ils this free face offers the door opening of a manufacturing process on, which will then be designed without gate supports, however , the operation of the known device is relatively easy to use.

The invention is based on the objective bell body for larger building ze Ilen said * rt _ * - Hllel> iandig ₃ but rdt low Entschalungsatifwand connect to t!

To solve this problem, the method according to the invention provides that the ceiling formwork of the shuttering is left in the same position during the entire production process and the corner joint seals are also pulled out when the side edges of the shuttering core are drawn in. Two possible solutions are particularly useful The first possibility is based on the prior art described, in which the formwork core is arranged in a stationary manner and a crane is provided for lifting the porno from ¹ formwork core, and it is provided that. the molding is released from the ceiling formwork by lifting it off with the crane, "after the second possibility, the invention provides that after the molding has been produced in the formwork, the entire formwork core is removed while the molding is removed from the mold

Slab formwork lowered; vriLrc .. until the ceiling formwork is at the same level as vrlrd, and then a known vehicle with Kuborganen is retracted into the molding and these are raised by the lifting organs and so on the vehicle vo? i Schalu23 £ 3 is extended there.

A device according to the Errindur- £ ^to ^ * Ansfuhrunz ^ ^sr> first alternative method is by a stationary support of the slabs sovrie before or znsaissen nit the side-forms einsiehbare Eckfugendichtursgen gekersnzeiciinei; -Sine device according to the invention for the execution of the second alternative method is by before or Zusacren Corner joint seals that can be retracted with the side formwork as well as the display of the entire formwork core on a lifting platform, on which the formwork core can be lowered to a floor-level position of its ceiling formwork. It should benerkt, Uzb the lifting elements of the vehicle thereby pneumatically, hydraulically, can be electrically or mechanically actuated. In order to avoid reinforcements on the corner of the blank, the lifting elements attack the corner vigorously under the side walls of the blank. With this solution, the crane and thus large hall heights can be avoided.

The invention offers the advantage of being relatively less. Expenditure on being able to produce parallel-walled, larger building construction cells ₃ v / ie outer ear cells and prefabricated garages. In this case, however, it is not necessary to provide large hydraulic forces for lifting the preform in front of the inner shell, although the ceiling formwork is rigidly arranged. In addition, the gate

Achieve perfect corner joint sealing of the inner core without first having to detach the corner joint seals from the remaining formwork panels of the inner core when the mold is being cut. The elastically resilient strelves of material at the horizontal corner joints can be removed from the molded product simply by pulling in the side formwork of the formwork. With the vertical

However, when the material strips are drawn in, the two side formworks have corner joints - both of which move inwards

the corner joint seals arranged in the vertically extending corner joints are elastically flexible strips of material which are permanently attached to the respective adjacent side formwork, and that these vertical corner joint seals can be supported on their inside by retractable support blades ] v / what they do when the side formwork is extended under ν ^ ηήχχτιζ, look outwards.

With a suitable choice of liafcerial for the flexible material strips their wear and tear is also negligible. In question korussn square profiles made of gu * r.nielastic material, e.g. Üeoprennuruni, or strips of material made of spring steel sheet.

It is, however, also possible to do without such sealing strips at least at the vertical corner joints, which are less affected than the horizontal corner joints by the presence of short residual joints _{3 in} that at least the vertical corner joint seals are retractable sealing swords. Possible forms of construction envisage that either a deep slot remains free at the edges of the extended side formwork that form the vertical corners of the formwork core, into which a knife-like sealing blade can be inserted, or the sealing blade has a stepped angular profile which, with a head part, extends into the vertical corner joint engages between the two extended side formwork and with one behind the

A sensible possibility of actuation for one that acts on a vertical joint seal Support sword or a sealing sword which itself serves as a seal arises when the respective support height or Sealing sword at one end attached to a bearing block and can be operated at its other end via a toggle lever is.

The ceiling formwork ", the Seitert formwork 5 senile, the outer formwork 8 are usually combined as double-walled specialist formwork from H-girders and formwork panels in the Heise r-jie shown.

The outer shells 8 of the device are external. Wa ^ en Io mounted, which run on rails 12, not shown, on wheels 12 embedded in the base 1 and from the one shown in FIG. The operating position shown in FIG. ¹ can be moved into the extended position shown in FIG. 1A.

The outer formwork 3 rises vertically and in a straight line from the vJagen Io ₃ , which can be moved by hand. The arrangement of two wheels in each case, one of which is offset in the direction of the device and the other in the outward direction, in relation to the vertically rising outer formwork 8, does not in this case provide for one Safety stop shown so that the respective outer formwork cannot overturn. \ Iie is further apparent from Fig. 7, in? four such extendable outer formworks 8 are provided. In the operating position of FIG. 1, these devices according to FIG. 7 can still be braced against one another by means of a releasable locking device 1 * 4 made of closures provided on the vertical edges of the outer formwork.

direction to manufacture the next bell body.

If you want to provide the bell body with door and window recesses, it is also possible to attach the corresponding built-in formwork to the outer formwork and "move" it out of your hardened molding. In this case, the external deoiling in the narrower sense, as shown in the examples, should be underfoot. Otherwise, however, within the scope of the invention, the term "extendable outer formwork" can also be understood very generally and also include, for example, any kind of folding movements.

The cover of the glove body 9 produced can in principle have any profile. In the exemplary embodiments shown, it is generally shown with parallel walls for use in residential building cells, but it can, for example, also have the form of a ceiling 8H shown in FIG Is formed like a tub.
