Prefabricated demountable column-free hall

Applicant: Friedrich Franz, Dudweiler / Saar, Kirschenstro2, Erwin Wiesel, Dudweiler / Saar, Gartenstrasse. 59

The invention relates to a prefabricated ^ pillar-free hall, as a spatial structure from an upper horizontal view! be in combination with vertical pane elements * As a result Due to its construction from prefabricated elements, it can be assembled and disassembled in a very short time. One frequent re-use in no way affects the stability of the construction.

It differs from the previously known lightweight halls They are mainly characterized by the fact that they are stiffened by parabolas made of structural steel or steel cables built into or under the roof takes place, which at their base points by turnbuckles and / or feathers are held. "

In the halls known so far, the horizontal forces were from wind mostly through, clamped supports and / or buckles recorded. This resulted in 'inevitably a limitation of the span and a correspondingly higher cost of materials'. It is known that the horizontal forces are generated by parabolic associations record in the roof of a hall. Up to now, however, these parabolic associations were rigidly designed and existed made of double T-beams or O-woods.

The invention is based on the object of making these stiffening parabolas cheaper and, at the same time, by using them a simpler and faster honing of the hall too reach. According to the invention, this object has been achieved in that the parabolas are made elastic from structural steel or steel cables exist, which are hinged to the roof elements that cross each other.

The accompanying drawings explain the inventive Hall on an exemplary embodiment.

The individual prefabricated V-wall elements 1 are double-shelled in a known manner and by inserted Mats made of glass wool or the like. Insulated. At their feet are they held in a!, - Profile 2, which is in a circumferential Banquet beam 3 is anchored. The wall elements set up next to one another are offset one above the other by arranged bed hook-like closures 4 connected and held. According to the invention, * the hooks 5 of these closures beveled on the inside of their free ends and their wedge surfaces, which adjoin these inclined surfaces via a rounding are hooked into the retaining plates 6 with prestress. In addition, the recesses of the retaining plates are tapered downwards from about twice to the single hook thickness. By this inventive design of the closures is a particularly rigid connection in all axes of the abutting one another Wall elements achieved.

The horizontal locking and the connection between the wall elements and the parabolic disk 7 forming the roof takes place via a circumferential laser sleeper 8 with a channel and a spring connection. The transfer of the horizontal wall load to the lower chords 9 of the roof takes place via the angle profiles 1o _t which connect the girders to the sleepers. Depending on the OMMM. 009816 / 02SS

Due to the length of the hall, the roof, which acts as a disc, is stiffened by two or more opposing parabolas made of structural steel or steel cables. These parabolas are pretensioned at their base points by turnbuckles and / or springs and are elastically attached to the individual lower chords of the roof by clamps 13 or the like at their points of intersection with the individual lower chords of the roof. In this way, the shape of the brabels is clearly ensured and the tensile forces occurring in them are introduced into the binder at the hinge points as compressive forces.

As already mentioned, several of these parabolic pairs can be arranged next to one another in very long halls. This inventive design makes it possible to design the halls with a large span relatively cheaply and to assemble and dismantle them quickly.
