Abstract

The utility model discloses a light high -strength prefabricated assembled ribbed slab type abutment, include: bottom support platform, ribbed slab is provided with two groups, two groups of ribbed slab symmetry fixed connection in the top surface of bottom support platform, platform cap shell is fixed in the top of ribbed slab, the top surface fixed connection of ribbed slab has I -steel connecting piece, and I -steel connecting piece inserts into platform cap shell, and fixedly connected with connecting reinforcing steel bar, back wall, back wall side two ends symmetry fixed connection has ear wall, back wall and ear wall integrated, and the outside of platform cap shell is fixed between back wall, wherein, after I -steel connecting piece inserts into platform cap shell, uses concrete pouring fixed. The utility model each component can be prefabricated in advance in factory. In construction site, only need to carry out simple assembling operation, has greatly shortened construction period. Compared with traditional on -the -spot pouring construction mode, need not to wait for concrete maintenance to reach design strength, has saved a lot of time.
