Road bridge of prefabricated components, which can be dismantled, has sleeves and pins to fasten and/or position the concrete slabs at the substructure

摘要

The road bridge of prefabricated components, which can be dismantled, has a substructure of prefabricated units and a road surface of separate prefabricated concrete slabs (11). Sleeves (12) and pins (13) are at the slabs and the substructure, which work together to fasten and/or position the slabs at the substructure. The slab has an opening (21) to take the sleeve, and head bolts (16) extending from the sleeve are anchored in the slab concrete. The pin has a thread (17) for a fastener.
