| 摘要 |
The present invention relates to a prefabricated bridge which is built by stacking precast blocks to build the piers used as the lower structure of the bridge. The present invention builds an uneven connection unit for the upper and lower blocks instead of using a separate connection apparatus such as a coupler or a rod to connect the upper and lower precast blocks to fit the upper blocks on top of the lower blocks and easily filling a filler such as non-shrink concrete in-between to complete the prefabricated bridge. The cut-off tension force delivery is delivered by the delivery friction force of the filler arranged between vertical main reinforcements arranged to overlap each other on a horizontal plane. |
