There is a substructure 12 on which the Quick-assembly hall roof 10 is stored. This substructure 12 consists of one as such for a long time well-known standard scaffolding with cross frame, with vertical supports, Diagonal bars, longitudinal bars and covering elements. The substructure 12 is stable on its own.

The substructure 12 is overall in a plan view seen all-round rectangular. The substructure 12 can also only be present on both long sides his. The cross frame with the vertical handles are in one given axis dimension X exists, in which axis dimension X too the roof trusses designed as truss gable roof trusses 50 of the roof are arranged. The roof trusses 50 are in their end region stored on support devices 20 which their bearing force on the vertical supports of the substructure Submit 12.

The bearing device 20 is in Fig. 1 with detail A. designated and shown in Figures 2a, 3 and 4 in more detail.

The truss roof trusses 50 are made of individual Truss truss units according to detail B, C, D, E composed what detail points in the pictures 6, 7, 8, 9 are shown in more detail.

The individual roof trusses 50 are by means 70, 72 for lateral supports according to details F and G supported laterally, which detail points F and G in the Figures 10 and 11 are shown in more detail.

Finally, in Fig. 1 there is a detail K, namely the Binder end area, framed by dashed lines, that in Fig. 12, 13, 14 is shown in more detail.

The support device shown in Figures 2a, 3 and 4 20 has a first support unit 22.1, a second support unit 22.2 and a third support unit 22.3, the third support unit 22.3 on a Support bracket 30 is mounted. Overall, the Support device 20 three degrees of freedom with respect to one Rotate the tie to be connected according to the arrows D1 (axis of rotation 24.1), D2 (axis of rotation 24.2) and D3 (axis of rotation 24.3).

The first support unit 22.1 is in the direction of two Pipe coupling units arranged at a distance from the axis of rotation 24.1 23 formed, which are suitable for the lower chord 52 (see Fig. 6 to 9), which is designed as a tubular hollow profile is to record. The axis corresponds to the axis of rotation 24.1 thus the axis of the assembled lower flange 52 of the Truss 50.

The pipe couplings 23 are on the second support unit 22.2 mounted, which is designed as a seesaw unit 25. About the rocking movement (rotation about the second axis of rotation 24.2 to enable according to arrow D2), the seesaw 25 via a bolt connection 27 to the flanges of the third Support unit 22.3 rotatably connected, the third Support unit 22.3 as a U-profile shoe 28 that is open at the top is trained.

The third degree of freedom, namely the rotation around the Axis of rotation 24.3 according to arrow D3 is possible in that the web of the U-profile shoe 28 over a single one Screw connection with a support rod unit 36 of the Support bracket 30 is connected.

The significant difference to the support device described above 20 is that on the one hand the Support bar unit 36 substantially parallel, i.e. horizontal is arranged to the substructure 12 and at the same time the Flanges of the U-profile shoe 28 (third support unit 22.3) enlarged compared to the embodiment of FIG. 2a are formed so that a relatively large rotation range D2 the second axis of rotation 24.2 for the seesaw beam 25 for Can be made available.

Fig. 5a shows the possibility of training the Truss truss 50 as a gable roof truss with the support on the support devices described above 20 through the degrees of freedom of rotation described above Support devices 20 can also be different Height levels of the substructure 12 in the right and left Support area can be balanced easily.

5b shows the use of a truss 59 in Frame of a pent roof, being scheduled between the left and right substructure 12 a height difference is available.

As already explained for Fig. 1, there is the truss 50 from truss units 50.1, 50.2, 50.3, 50.4, the are shown in Figures 6 to 9, the individual Truss truss units are designed to be pluggable. The truss unit 50.1, which in the end of the Binder is used is shown in Fig. 6. The Binder unit 50.1 has an upper flange 54 and one lower flange 52 running parallel thereto. In the left The top section is convex and runs downward then straight to the lower flange 52 available. The upper flange 54 is in the form of a welt rail profile 53 formed on both sides of a keder opening 55 for Pulling in a welt of a keder tarpaulin. Internally the keder rail profile 53 has a square recess 82 on.

The lower flange 52 is, as already mentioned, as a tubular profile educated.

Between the upper flange 54 and the lower flange 52 are alternating Posts 56 and rising and falling diagonals 58 arranged. Both the posts 56 and the diagonals 58 are designed as tubular profiles. You can also use it as a Be square or rectangular tube profiles.

In the upper third point are at the posts 56 to both Pages in the plane of the binder 50 protrusion units 40 welded, which also has a tubular hollow section form, the distance to the lower flange 52 in FIG dimension A is entered.

Fig. 7 shows a truss unit 50.2, which in Normal field of the binder 50 is used and a Truss field with a post 56 and one each has rising and falling diagonals 58. Same Components have the same reference number and are not explained again.

The truss unit 50.3 according to FIG. 8 differs differs from the truss unit 50.2 according to FIG. 7 by the fact that here two truss field units in a row are arranged.

Finally, in Fig. 9 there is also a truss unit 50.4 shown in the ridge point of the saddle roof is used, i.e. the connection to the right and left-hand inclined truss units 50.1, 50.2 or 50.3 allowed and the upper flange 54 on the lower flange 52 in Saddle point is curved.

To connect the truss unit 50.1 to the Truss truss unit 50.2 or 50.3 have both the latter in the top flange 54 and the Lower flange 52 attached pipe connectors 46 or 48, on which the corresponding lower flange 52 or Upper flange 54 of the truss unit 50.1 is attached. The upper pipe connector 46 is a square hollow profile and the lower pipe connector 48 as a round tubular hollow profile educated. The outer contour dimensions of the pipe connector 46, 48 are made slightly smaller than that Inner contour dimensions of the upper and lower chord 54, 52. The protrusion length L1 of the lower pipe connector 48 is opposite to the protrusion length L2 of the upper pipe connector 46 formed smaller, which is the assembly when Assembly of the truss units made easier. The difference the lengths L1 and L2 is U in Figures 7, 8 and 9 designated.

The truss unit 50.4 points to both of them Corresponding pipe connectors 46, 48 on the connection sides.

Figures 10 and 11 show means for lateral support of the binder 50. According to FIG. 10, a truss 72 be used, which consists of an upper flange 74 and a spaced parallel to the lower flange 76 consists of both belts as tubular profile units are formed and arranged at a distance A, the Distance of the projection units 40 to the lower flange 52 of the Binder 50 corresponds. In both end areas of the lower chord 76 are snap claws 60 and in both end regions of the Upper belts 74 there are hook-in units 62 which are in the Projection units 40 and the lower flange 52 of the Binders 50 can be snapped into place, the Snap opening 64 of snap unit 60 of lower flange 76 a spring-loaded pawl 66, which is in the claw 68 arranged tube profile secures. Between Upper chord 74 and lower chord 76 are in turn as tubular profile units trained posts 79 or rising and falling diagonals 78. The system length dimension the connection points of the snap claws 60 and 62 is indicated by X in FIG. 10 and corresponds to the system dimension X according to FIG. 1, namely the lateral spacing of the trusses among themselves. Because only on the lower flange 76 Snap-in units 60 with pawls 66 are available on both sides simple assembly with two people is possible.

Another embodiment of a lateral support is shown in Fig. 11. There will be an easy one Pipe profile rod 70 used, at its two end regions each described snap claw 60 is arranged. The As such, latch claw 60 is from the mobile scaffolding area known and described in EP 0 348 885 B1.

The distance A is like this dimensioned that between the projection units 40 and the Upper chord 54 has enough space to accommodate two snap claws 60 to be connected horizontally one above the other.

The length of the projection unit 40 is dimensioned such that a Hook-in unit 62 can be easily hooked in and on the outside an additional securing element 67 against Slipping of the hanging unit 62 is present.

The manual assembly of the overall construction can be done like described below as an example implemented as follows become. First, the substructure 12 is made up from a well-known system framework, created manually. Then on the floor, the truss 50 from the truss units 50.1, 50.2, 50.3, 50.4 - depending on the span - composed. The support devices 20 are on the vertical supports of the substructure 12 are mounted. On prefabricated roof truss 50 is on the upper Level of the substructure 12 raised and there in such a way filed that the truss plane is essentially horizontal is arranged, the end regions of the binder 50 in arranged in the immediate vicinity of the support devices 20 are and if necessary - depending on the span and roof pitch - In the middle of the flat arranged binder 50 a mobile Mobile scaffolding as a temporary support structure is arranged. Because of the three degrees of freedom of rotation each Support device 20 can be aligned so that the lower flange 52 of the tie 50 can be easily inserted into the Pipe coupling units 23 of the first support unit 22.1 can be inserted and temporarily closed, see above that rotation of the lower flange 52 of the tie 50 in the Pipe coupling units 23 is possible. After that judges one installer each, located in the area of the support device 20 is located - possibly a third fitter, for example on the mobile tower in the Center - the binder 50 is in its vertical position (Rotation D1), the second bearing unit 22.2 and the third bearing unit 22.3 accordingly Rotate axis of rotation 24.2 and 24.3 so that in the final state the Binder 50 with a vertically arranged plane is present. In In this state, the pipe coupling units 23 become firm tightened so that the binder 50 is held in this position is. The same assembly process takes place on the in the Pitch X adjacent roof truss 50. As soon as two roof trusses 50 are mounted accordingly, the Means for lateral support are drawn in. these are on the one hand the truss rods 72, with their connections (60, 62) to the protrusion units 40 of the posts 56 and the Lower flange 52 can be connected. In addition, in the field between two roof trusses 50 rods 70 in Area between the protrusion units 40 and the top chord 54 of a roof truss 50 to the post 56 on the Snap-in unit connected, which run diagonally. As soon as a third roof truss 50 is mounted, this is over extending perpendicular to the plane of the rods 70 to the Projection units 40 and / or the lower flange 52 connected bars laterally secured.

Overall, a stable one is created step by step spatial hall roof 10, simply because of a simple and easy manual assembly by two, maximum three Fitters.

As already described on the occasion of FIG. 1, this is Quick-assembly hall roof 10 in the illustrated Embodiment designed as a so-called keder roof, i.e. that between the top chords 54 of the trusses 50 each a keder tarpaulin 42 with corresponding edge piping in the Openings 55 of the welt rail profile 53 is drawn in the inside of the object surrounded by the construction secure against weather influences.

Because of the hall roof according to the invention particularly advantageous design variants of the guides the keder tarpaulin 42 between the individual ties 50 and adjoining underside wall construction.
