| 摘要 |
<p>The invention concerns an expansion joint (10) for installation across a gap between adjacent concrete slabs (2, 2') in a civil engineering structure, the slabs (2, 2') having in the area of said gap a front side (3, 3'), the expansion joint (10) including i) an elongated rigid bridging member (15) for spanning said gap and ii) elongated elastically yielding members (35, 35') yielding elastically in response to dimensional changes of said slabs (2, 2') and adjoining said bridging member (15), the elastically yielding members (35, 35') being adapted to be supported by a respective concrete slab (2, 2') near said front side (3, 3'). The elastically yielding members (35, 35') are preformed blocks that include means for the connection thereof to the bridging member (15) as well as to the respective concrete slab (2, 2'). <IMAGE></p> |
