Instead of the above-described special pipes 14, other Hoiilprofile can .as for example rectangular Iastenprofile 14 'of FIG. 3', 4 'xmü 5' FHR the upper chords of the carrier 2 may be used. The edges of the shuttering panels 1 can then simply be formed at right angles and placed on the surface of the box profiles 14 * , to secure the panels 1 against falling down, simple angle irons 14 '* are then welded onto the box profiles 14 ⁵ with the flange facing upwards. The rectangular panel edges slide under the flange of this angle iron ₅ on one side, which means that the formwork panels are also inevitably removed from the ceiling when the formwork is removed «,

Β to the booms and 7>'or' 6 'and 7 ¹ are mounted at regular intervals smaller markers at which the projection of the cantilever arms 6 and bridging beams 7 can be read directly on a Zentiraeter / accuracy.

As already ermähnt, the carrier top chords 14 by cantilever arms aussiehbare S or ^ erbriickungstrager 7 (FIG. 1) .. This -verlängerbar boom 6.7 consist of ßpezialrohren (fig. 4, 5 and 6) with the '' S ⁵ Orm . der Srägerobergurte 14. The dimensions of the ' Ausleger Bind ' are slightly smaller so that they can be used with. 'Sufficient' play space can be introduced into the top chord profiles. On the boom are web caps 24 '(Fig _8, 1,6 and 7) for. On the support of the formwork • panels 1 at the places.-pushed., At '' which. 2 corner corners of the Sehalung panels 1 - collide.

In Yerwendunfj on the other hollow profiles or the boom 6 · 7 and the ridge caps 24 are to be formed the hollow profiles .entsprechend. -i? ar the box profile example, the jib profile 6 ^f or -7 'and the web caps 24' according to Fig ₃ 4 _S ¹ 5 ' and. 6 ^?

Are the construction and dismantling of the new formwork equipment is very simple and can easily by semi-skilled labor, made "First-ceiling support 2 ge one lying on the ground, or. attached to the / Haumwand leaning. pair of supports and by Sifibau the struts 8 Tersteiftc The thus formed, transverse frames are erected and placed in the correct position _s ./so "that the connection of the transverse frames 'under themselves' by attaching the longitudinal frame struts 9 ? 1o and 11 is possible, "Hereafter, the cantilevers 6 or bypass carrier 7 sucked in accordance with the BauiraeaBen and secured with the latch bolt 27 after, 6 and 7 and for each of them provided Formboards on-.END the boom - longitudinal joint the corresponding - ^ uia were postponed ßtegkappen Stücksahl, FINAL is then loosely placing the formwork panels 1 from above .. the reduction is carried out in reverse order first the Diagonalstre be ben 11 expanded the longitudinal frame =..

With the help of the foot spine 4J, all supports are lowered _{about two turns f,} then the transverse beams on the side provided with the marking points 2J under the formwork panels 1, starting one after the other at least 5 cm, with the formwork panels 1 through the Profiling of the panel edges 12 · or 12 ⁵ and the upper chords 14 or 14 'are automatically detached from the ceiling. Then the formwork panels 1 are to be removed by hand. Hachdem the horizontal struts 9 and Io are removed, the cross frame, folded and apart-gen ommn -Will can,

Naturally, the possibilities for implementing the invention are not exhausted by the example shown? much more it is possible j the one construction element of the new formwork device, depending on the area adapt «. So too are 'changes-on'. other building materials, for example on light metal carbon striations, without further ado you rchf ülirb a r "
