Speedy Scaffolding

Layher's Allround bridging system is the ideal solution for the fine nuances of scaffolding.

With over 60 years of experience in producing high-quality scaffolding systems, the Layher Group in Germany now has 30 sales subsidiaries worldwide. Its Allround bridging systems is a modular truss system that can be adapted to applications where the wedge heads can be welded to the side and the Allround equipment can be fastened. Mithilesh Kumar, Director, Layher scaffolding systems, explains the features of these systems in detail.

Bridging focus A standard Layher bridge structure mainly comprises two loads transferring Allround bridging systems. It is arranged parallel to one another at a definite distance. A stable bridge-supporting structure is obtained with an internal Allround scaffolding structure fastened between the two systems. The stiffening in the transverse direction and the stabilisation is achieved with horizontally arranged bracing of the structure. The bridge decking and the guard rails are fastened to the internal scaffolding structure. The entire bridge structure is finally supported at the bridge ends. The support can, for example, be on individual Layher heavy-duty supports integrated into a separate stairway access. In some cases, it is also possible to support the end posts of the bridge directly on existing foundations, beams or walls.

System application
The renovation of the Swiss motorway was to be done in three phases; this includes an overpass near Seedorf. This overpass crosses not only the Gotthard Route, one of the most important north-south axes in Europe but also the fourth biggest river in Switzerland, the Reuss. As a substitute for the closed bridges, a temporary pedestrian crossing, which was to cross the motorway and the river parallel to the existing bridge, was to be constructed. Layher's innovative Allround systems were put to task. In order to cause minimal traffic disruptions, the construction was pre-assembled on the ground. To bridge road and river, provisions were made for two sections of 31 m each. To compensate deflexion, these were constructed with lengthwise adjustable diagonal brace with a slight cant. The builders were then able to assemble the two parts of the bridge onto the support. Also the accesses and middle section were constructed with the help of Allround scaffolding.
