Overview of strut frame bridges made from timber

Obliquely supported

The main structure consists either of a block-bonded laminated timber panel or individual laminated timber supports which are braced downwards with slanting intermediate supports. This reduces the static support width and more economical cross sections are possible.

On its top side, the supporting structure has a roadway surface with a thick mastic asphalt or a sheet metal covering with an overlaid surface so that an optimum structural protection of the timber is achieved.
The railings are attached to the side of the main girders. This design is optimally suitable for cuttings.
