Carriageway girders for monorail lower flange trolleys with reinforcement parts attached to the upper chord

The firing concerns a track girder for a lower flange trolleyD with reinforcement parts attached to your top belt.

In the known roadways of this type, commercially available double T-beams are generally used, the use of which especially uei larger spans is uneconomical, as this is in view of the permissible deflection according to the required moment of inertia - have to be dimensioned, while they are far from being used in terms of tension are. On the basis of this knowledge, the move has been made to use wearers with a low load-bearing capacity reinforce that flat iron supports are welded onto the flanges will. In addition, girders are known whose upper flange has wide flat steels or U-joints welded onto them to prevent the upper strap from buckling. These known support Ausfabrunden are disadvantageous in that with them the dead weight and also the manufacturing costs are significantly increased. In contrast, the achieved The benefit, namely the increase in the moment of inertia, is relatively small.

The task on which the innovation is based is to create a roadway door that can be manufactured economically bar and which also has a large moment of inertia and a high degree of tipping safety and torsional rigidity having. According to the innovation, this is

kungteil reached, which together with the outer surface of the Upper chord forms a hollow profile and both parts are connected to one another at their joints by welding. The cross section of the hollow profile advantageously has the shape of a polygon or a shape deviating therefrom on.

In the drawing are exemplary embodiments after the grooming shown.

Figure 1 shows a cross section of a railway carrier, the one with a trapezoidal reinforcement ^ part

is provided and

FIG. 2 shows such a carrier with a reinforcement part which has a pentagonal cross section.

The commercially available roadway girder 1 looks in a well-known -Depending on the lower chord 2, the web 3 and the upper chord The reinforcement part 5, which - as shown in FIG. 1 - has a trapezoidal cross-section, is attached to the upper belt and - as shown in Fig. 2 - has a pentagonal cross-section, the top belt 4 each having the forms one side of the polygon. Instead of the polygonal cross-sections, other axially symmetrical cross-sections can also be used Cross-sectional shapes, for example circular-sector or elliptical-sector-shaped cross-sections, are used, the cutting width of the sector section corresponds to the width of the O ^ belt. The trough-shaped reinforcement parts produced in this way are connected to the upper belt 4 in the in the Figures shown welded way. The weld seams are denoted by 6 and 7.

The subject of the innovation is not limited to the specified embodiments, but it can be in multiple Wbise be modified. So it is B. possible and advantageous that the ends of the side flanks of the reinforcement part Be flanged in a U-shape and these flanges around the edges of the o ^ ergartes in a claw-like manner.
