Fig. 4 shows the junction of two over their entire length adjacent roadway parts 1 in cross section. It can be seen in particular from Fig. 4 that the tabs 8 on the inner cross members 4 or the openings of these tabs lie on top of one another, whereby a connection of the inner cross members 4 by means of bolts becomes possible. Furthermore, the lugs 7 on the upper plates 6 form a recess which is filled with the sealing compound. Due to this sealing and the coating of the upper plate 6, the roadway parts 1 lying next to one another form one completely even, flat surface.

Fig. 5 is a longitudinal section through two roadway parts 1 lying one behind the other with the outer or from an I-beam Portal traverse 11, which is provided on its upper flange with the bolts 12, which are in the corresponding recesses 3 of the lane parts 1 grip. In the case of 1500 mm wide roadway parts 1, two recesses are sufficient for their proper connection 3 and two bolts per part of the roadway. A seal 13 is introduced between the upper ends of the roadway parts 1 in a known manner.

To be able to build temporary bridges and viaducts faster Advantageously, existing supports are used, each of which has a bolted end plate at the top, on the over corresponding openings of the lower flange of the portal cross member 11 is placed. The lower end plate of each support also has Openings into which the bolts of a steel base plate engage, which rests on a concrete foundation erected on piles when the soil conditions require it.

The road edges consist of continuous edge parts 14, which are connected to the Fahrbalinteile 1 by bolts. Pig. 6th represents such an edge-

part 14 in cross-section. The long edge part 14 consists of a stand with traverse 15, the. a rain gutter 16, a rebound surface 17 and a sidewalk 18 form the channel 16, the rebound surface 17 and sidewalk 18 are made from the reinforcements of the Shaped sheet metal construction. The edge part traverse 15 has tabs 8, their openings on those of the tabs 8 on the inner cross member 4 of the roadway part 1, so that the edge part traverse 15 can be connected to the inner traverse 4 by means of bolts.

Vory is derived from the description of these exemplary embodiments that the method for building viaducts from the components described is particularly easy and quick to carry out, since it requires neither complicated connecting parts nor special or many workers.

When building viaducts, the portal supports are in the desired Distances set up and then placed the portal crossbars 11 on the portal supports, the portal supports with the portal crossbars 11 via the in the lower flange of the portal crossbars 11 provided openings and the bolts are connected to the supports · Then the roadway parts 1 with their ends placed on the portal crossbeams 11 and the recesses 3 provided in the ends 2 over the bolts of the inner crossbeam inserted and finally the tabs 8 on the inner cross members 4 of this roadway parts 1 by means of bolts with the tabs 8 on the Inner cross members 4 of the roadway parts 1 lying next to them and connected to the edge parts 14 with the tabs 8 · Then only needs nor the asphalt or another sealing compound to be poured between the individual roadway parts 1.

will. Also, as already mentioned, the connection of two roadway parts 1 lying one behind the other can not be done by means of an external crossbeam 11, as shown in FIG Bolt has _o Fig _o 7 shows an example of the connection of two roadway parts 1 lying one behind the other by means of such an intermediate piece 19 in cross section. The intermediate piece 19 has the shape of a right-angled trapezoid and has an inclined side with the same angle of inclination as the one roadway part 1, to which it is fastened in a known manner, for example by screws. The intermediate piece 19 is also provided with bolts 12, which in grab the recesses of the other mobile beam part 1. In the case of 25,000 mm long roadway parts 1 with intermediate pieces 19, it is not necessary to provide a portal at each connection point between the roadway parts 1, ie every 25,000 mm. Rather, the portals can be arranged in the area of the first or the second inner traverse 4 _o The distance between the portals can thus be set at approx. 15500 to 34500 mm, depending on the requirements of the passage under the provisional viaduct ·

The distance between the supports of the portal traversel can also be changed and the length of the portal trusses 11 are chosen so that they meet the requirements of vehicle traffic under the viaduct correspond. To reduce the number of components for the viaducts, for example, supports 20 with 2000 mm, 4500 mm and 6000 mm spacing and portal crossbars 11 of 5200 mm, 8200, Mn, and 9200 mm length are used. Such components allow different Combinations, some of which are shown schematically in Figures 8-12. Show:

ßerde »they can be formed at an angle so that the ends of the viaduct can be practically brought to the ground, with one between the end of the steel viaduct and the ground Concrete structure is planned «For a 4500 mm high viaduct the slope of the last parts of the road is advantageously 3.5 *.

The demolition of such a provisional viaduct or such a bridge is particularly easy and quick to carry out, since it is sufficient to remove the connecting bolts of the roadway and the edge parts and parts from the bolts of the supporting parts gain weight. All parts can then be stored for reuse. Due to their geometric shape, the Roadway parts alternately turned inside out and stored next to each other and thus stored in a confined space and also transported in a space-saving manner will·
