is used

The invention relates to a fitting for connecting the rods of trusses or the like. It is particularly useful when building metal roof trusses from folded sheet metal or rolled steel profile bars to use.

The shaped piece according to the invention enables the framework bars to be connected to one another to give the intended direction immediately. It can also be used to assemble the framework can be carried out very quickly without the need for trained skilled workers.

For example, various embodiments of the molded piece according to the invention are adjusted described on the basis of the drawing.

Fig. Ι represents a partial view of a roof structure made of metal during manufacture;

Figs. 2 through 7 are perspective views of various Fittings that are used in the manufacture of such a roof truss to connect the structural elements to one another will;

Figure 8 is a perspective view of a detail of the Roof Truss®;

Fig. 9 and io show a perspective view the devices to be used in the center of the truss;

Fig. 11 is a section along line XI-XI of Fig. G ;

Figs. 12 and 13 show a perspective view Fittings for intermediate nodes in the roof truss construction;

Figure 14 is a perspective view of a fitting for a junction connection with Purlin joint.

Fig. 2 illustrates the shaped piece a at a ridge node of the roof structure, which through

its connecting piece α ¹ , α ^2, the two upper chord parts ι and 2, through its lower connecting piece α ³ the vertical rod 3 and by means of its connecting piece α * and a ⁵ the ridge purlins 4, 5 with each other.

Fig. 3 shows the shaped piece b for the lower central node of the roof structure, which the two lower chord parts 6 and 7 of the same by means of its connecting ^{pieces b 1} , b ² , the vertical rod 3

ίο by means of its upper connection stub b ^s and the lower longitudinal connecting rods 8, 9 by means of its stub fr * and b ⁵ connects to one another.

Figure 4 shows one of the upper interconnections; the upper connection clip c ¹ this

The shaped piece is attached to the top chord (rafter) 1 of the roof structure. Its lower connector c ² is attached to one of the intermediate verticals 10 and its transverse connector c ³ , c * are attached to intermediate purlins 11, 12, where 'the connector c ³ also with a

ao parallel to the vertical ίο of the tie rod 13 can be connected.

Fig. S illustrates one of the lower interconnections d ; the lower connection stub d ^{1 of} this shaped piece is attached to the lower chord part 6 of the roof structure and its upper stub end ² to the lower part of the vertical 10. The cross stubs d ^s , d ^{l in} turn are connected to the longitudinal connecting rods 14, 15.

On the truss foot (Fig. 6) molded pieces e are provided, the connecting ^{pieces e 1} , e ^{2 of} which are used to connect the upper chord 1 to the lower chord 6 of the roof structure. These fittings also have cross-pieces e ^s and e *, the purpose of which is to attach the purlins.

Fig. 7 illustrates a fitting /, the connection clip f ^{1 is} firmly connected to a post 17, while his, nozzle / ² , / ³ a member 16 connect.

The fittings according to Figs. 9 and 10 are only for connecting the middle Vertical rod with the (belt rods of the tie determined.

The ridge knot fitting shown in Fig. 9 has two connection pieces 21 ⁶ , which are symmetrical with respect to a third nozzle 2> i ^c and form an angle with it which is equal to that of the roof pitch. At their edges, the connecting pieces 2i ^a , 21 ⁶ , 21 ″ are reinforced so that they can be inserted into the profile bars A and B , which form the rafters and the vertical. At a small distance from these edges, the molding has a cavity which is open on one of its broad sides (Fig. 11), but with beads 24 remaining through which holes for the passage of connecting bolts or rivets are drilled. The bottom of this cavity has protruding ribs 25 in a crossed arrangement.

The device according to Fig. 10 is very similar according to Fig. 9 with regard to their arrangement.

However, it has between the connection nozzles 26 ", 2.Θ, which are on both sides of a nozzle 26 ^C , additional nozzles 27 ⁰ , 2! 7 ^& , which are intended for the connection of diagonal bars.

The fittings shown in Figs. Γ2 and 13 only have an additional connection piece 28, 29 on one side, which is also for the connection of diagonal bars is intended.

It is advisable to use fittings such as the one shown in Fig. 14 for the butt joint of the purlins to be provided.

In this fitting, a two-sided connecting piece 30 intended for the connection of the purlins is carried by the back of a bow-shaped connecting piece 31, which is placed in a riding arrangement on a rafter A and attached to it in a desired position. The connecting piece 30, like those of the fittings according to FIGS. 9 to 113, is designed as a hollow body.

The shaped pieces described can be made of any suitable material, such as Metal, namely light metal alloys, cast iron, cast steel, alloys based on Copper, or made of non-metallic materials such as wood or plastics.

Of course, the subject matter of the invention is not limited to those described in detail above Embodiments are limited, but can be modified in various ways, in particular depending on the number of mit-go elements to be connected to one another and their directions to one another.
