Rod-shaped supporting structure – tennis hall twins

Game, Set and Match. This has been possible again for over a year in the two tennis and event halls on the Bürgenstock. Since then, the resort on the mountain ridge in the Swiss canton of Nidwalden – impressively visible from the city of Lucerne – has been back in operation.
Steel parts should be as invisible as possible. With classical connections, however, slip and assembly tolerances would lead to large deformations at the sleeper. With a grouting joint developed specifically for this project using GSA® technology, the girders could be joined flush, precisely and force-closed. GSA® threaded rods were glued into the glulam with epoxy resin.
