The locking bar 12 is in the embodiment shown made in the form of a rigging screw with a sleeve part 27 which in darna is provided with internal threading. In each of the threaded end portions of the sleeve member are screwed into a rod 28 with adapted external threading. Rod 28 is included its one end attached to a transverse bearing sleeve 29 which is pivotally mounted on a layer extending therethrough. The bracket 13 is made in the form of a transverse section U-shaped profile rail with a waist part 31 and two to connecting side flanges 32. The bearing pin 30 extends thus through both the bearing sleeve 29 and the side flanges 32. The bearing pin 30 is suitably detachable from the bearing sleeve and the side flange, so that the locking bar 12 can be released from 10 15 20 25 30 35 9 510 sas its mounts. Fig. 7 shows only a side part of the leading beam piece 5, 6 in cross section. It appears that from the outside of the web 31 projects engaging portions 33 which hook formally encloses the edge portions of the attachment of the beam piece. 19 in the undercut grooves. Denoted by 34 a stop plate resting on the bottom of the U-profile, in which in the embodiment shown, two screws are screwed in. was with rounded head and internal key grip removal.

The screws, which of course can have a different number than two extend through in the beam piece 5, 6 and the body part 31 holes, and their projections from the stop plate 34 the portion is adjustable by tightening the screws 35 in the corresponding thread in the stop plate 34. The U-profile of the stay bracket 13 is widened closest to the bottom of the profile, ie livdel 31, the rest of the side flanges form an abutment ledge 36 and the transition from this widened part to it which constitutes a restriction on the movement of the stop plate 34 in direction of the arrow A. In Fig. 7, the locking bar 12 is removed nat. The projection of the locking pin formed by the screw 35 outside the stop plate, ie into the corresponding recesses in the 31 and the wall of the beam piece are so adapted that the locking pin 35 is pulled out of the beam piece but still inserted in the recess in the web part 31 when the stop plate 34 abuts the abutment ledges 36 in the removed condition of locking bar 12. If the offset position of the bar bracket 13 is with the beam piece desired to change and locking desired can be performed in different offset positions is appropriate the beam profile provided with a number in suitable places provided recesses for the locking pin 35. When the locking bar is removed from the stay bracket, the stay bracket with stop plate tan 34 raised against the abutment ledge 36 is displaced along and released from the beam piece. In from the beam piece free- made condition, however, the stop plate 34 is retained with it locking pins 35 intact in the tie bracket, which means that these parts are always in place when reassembling shall be done. the plate by abutment against the bearing sleeve 29 towards the web part 31 When the locking bar 12 is mounted, the stop depressed position, i.e. in a position in which the locking pins 35 are 510 sas 10 10 20 25 30 35 inserted into the wall of the beam piece and thus the stay bracket securely held in its intended position on the beam piece even at heavy load. The angular position of the side beam piece 5 i relation to the roof beam piece 6, ie the angle α can at the embodiment shown is varied both by changing the the length of the locking stay as by changing the stay bracket 13 position on each beam piece. In the embodiment shown the stay bracket is made as a string profile, but it is located also within the scope of the invention to perform the engaging portions 33 different than in the form of longitudinal strips. For example it is within the scope of the invention to perform these gripping portions such as short hooks, which are arranged with suitable intervals along the stay bracket.

The one indicated in Fig. 1 by 16 and by impeller 15 8-10. Foot- outer shape that it provided foot part is shown in more detail in fig. the part 16 has a plug-in portion 16a, the fits in the recess 17 in the side beam piece 5 so, form fitting can be inserted therein. 37 denotes a man- tele part which in its external form connects to the beam piece as well as the jacket parts 20 and 21 described above on the two connecting pieces 8 and 9, respectively. Two are denoted by 38 projecting bearing ears with mutually coaxial shaft bores 39. With one not shown in the drawings, through these shaft bores extending shaft 40 is an impeller 15 rotatably mounted in the foot portion 16. As shown in Fig. 8 the impeller has a cross-sectional running track in it periphery. The running rail 14 laid on the base U is shown sar a correspondingly rounded running head 41. By this rounding of the periphery of the impeller 15 and the impeller of the rail head 41, the foot portion 16 can be placed on and moved along the rail. len 14 with varying slope. Due to the impeller possibility to rest against the rail with different shaft inclination with one and the same cover construction, adaptation can take place within relatively wide limits to the surface desired to stand available during the roof construction, which the distance between the rails 14. Adaptation can thus was done by changing the inclination of the side beam pieces 5 location. In the embodiment shown in Fig. 9, the foot 10 15 20 25 30 35 ll 510 688 16 between the bearing ears 39 a central cavity 42. I removed condition of the impeller can be inserted into this cavity a matching insert 43, preferably with orange cross-section as well as preferably the cavity 42 sar orange cross section. With the insert part 43 is via a joint 44 articulated to a footplate 45. Suitably, in the the plug member made a number of transverse mounting holes 46 for enabling variation in the insert 43 insertion depth in the foot part 16. Adjusting the height position can by inserting a pin 40 through the holes 39 in the the tubes 38 and the appropriate hole 46 in the insert. Suitable gen is the insert part of the foot part 16 in the beam piece so adapted that it can be rotated 90 ° relative to the direction shown in Fig. 8, i.e. the direction of the impeller will end up at a 90 ° angle to that of the drawing showed. In this position of the foot part can place for the foot plate 45 shown on the right in Figure 8 rest against the base 17 during the rest of the frame structure. and instead of the support plate 45 sliding along the substrate in the direction of the one marked with B in Figure 8 the arrow, the impeller 15 can roll on the ground. Possibly the impeller 15 can in this case be replaced by a well-adapted impeller, for example with a soft peri- holiday. Possibly can to enable this movement be laid out one in the direction of movement, i.e. angular right towards the rail 14 directed additional rail used just below the rising moment. The foot plate 45 can in that case running rail 14 is not required to be attached directly to the substrate with partly through its holes 47 led sprints or the like. For to counteract lifting forces on the structure can on foot be attached to a safety device 53, as marked with dashed lines in Fig. 8, which is preferably hook-shaped grips a flange on the rail 14 or is otherwise assembled man-connectable with the rails. The safety device and / or the foot may suitably be provided with a number for bolt passages. intended holes for adjusting the assembly of the safety device position of the foot part in relation to the rail independently 510 688 12 20 25 30 35 those of the slope of the side beam and thus the foot and possibly the height location. 4 are attached Denoted by 48 fasteners which are fastened by means of bolts 49 or the like Figure 11 shows how the distance barriers 3, between the side and roof beam pieces 5, 6. in the sides of the beam pieces or in between element. The fasteners have a central cut groove 50 and laterally projecting mounting ears 48a in which the tensioning ropes 10 can be hooked by means of hooks 51 or smiles similarly. 52 denotes an end end of each end. that of the spacer boom 3, 4 which is centrally provided with a flange 53, 54 which is insertable into the undercut groove 50. which ultimately has a thickened edge portion Fastening The claws 48 can of course be attached to any suitable place on the frame arches, ie also on the bracket brackets 13 as shown in figure 1.

In the following, with reference to Figure 12-16 describes an appropriate approach when erecting In Figure 12, they have various elements included in the frame construction the frame structure according to the invention. via the respective coupling pieces, joint pieces, spacer mar, straps, etc. However, the locking bars 12 have not yet been attached. In this mode, it is easy to work with assembly because the construction height is relatively low and installation can be done with relatively simple equipment without the need to use tall cranes and the like das. It is also possible to retract the current cover 11 with its corpses in those extending along the various elements Figure 13 has lifting device 55, fastening grooves 18. In appropriate gene one at each body arc, applied in the vicinity of one of the hinge parts between the roof beam pieces and the side the beam pieces, namely the one according to figure 12-16 left members. From the downward angled position shown in Figure 12 the beam parts have been raised to an upwardly angled position. When clamping force is applied between the opposite joint 7 and the part 16 can, team, the lifting continue until the foot part has while the foot part 16 slides towards the bottom continue to the vicinity of the corresponding rail 14. After lifting 10 15 20 25 30 35 13 510 ess of the foot part on this rail, after the foot part fitted with the impeller 15 if this has not been mounted from initially, the locking bar 12 can be fitted to lock the winch the position between the roof beam pieces and the side beam pieces.

Thereafter, the corresponding procedure can be repeated the other side as shown in Figure 16, after which also the locking bar on this side can be fitted. After the rise the length of the locking bars can be suitably adjusted by turning the water screws. In case there is a construction crane or similar available on site, this can of course be used for the rise. In such a case, suitable lifting brackets may be fitted. as on the roof beams' central grip strips with grip edges which surrounds the edges of the strips and extends into them undercut tracks that occur there. The composition of the various parts included in the frame construction are obvious for the person skilled in the art by studying the therefore, this composition need not be described here.

The invention has been described in the form of a preferred one execution, but the same can of course be varied to their details within the scope of the following claims without departing from the basic idea of the invention. Thus the cross section of the different profile parts may have different shaping, the location of the engagement grooves may be different than that shown in the drawings. The plug-in parts can possibly be designed as the beam pieces enclosing the lar instead. When in the description the term "body arches" used, of course, does not necessarily mean parts with the shape shown in the drawings without these elements can of course have both arcuate curved shape. Thus, vis- said of the roof beam pieces and the side beam pieces to be curved while others are straight. The s.k. the frame arches do not need complete have a symmetrical shape but the shape can be adjusted the requests made by the user without the basic idea of the invention is thus departed from. Additional variations are conceivable within the framework of subsequent tent requirements. For example, the joint piece 7 can be used on others places other than between the side beam piece and the roof beam piece, such as 510 688 14 10 between two adjoining roof beam pieces to formation of an adjustable axis or other roof break. The may also be arranged between two interrelated other side beam pieces. Likewise, the rigid coupling the elements within wide limits have a different location than the one on the drawings showed. The cover element can also be desired if desired be of rigid design, such as roofing sheet or similar. The screws 35 can be replaced by in the stop plate tan 34 welded or otherwise attached pins. Further the half-profile of the beam pieces need not be completely closed in the the circuit direction calculated. Thus, for example, a page be fully or partially open.
