Description

Prefabricated tool type steel shielding plate at expansion joint of bridge anti-collision wall Technical Field The utility model relates to the technical field of bridge engineering protection, in particular to a prefabricated tool type steel shielding plate at an expansion joint of a bridge anti-collision wall. Background The bridge anticollision wall is the important safety protection structure of bridge, and bridge anticollision wall expansion joint is the important construction part in the bridge anticollision wall structure, and it is corresponding with bridge main part expansion joint, has important meaning to the security and the durability of bridge, and the bridge can produce flexible deformation because of factors such as temperature variation, concrete shrink creep, vehicle load in the use, and bridge anticollision wall expansion joint can provide deformation space for anticollision wall, prevents that the anticollision wall from producing crack, damage because of unable free flexible to guarantee the normal performance of protection function of anticollision wall. The expansion joint is required to be provided with corresponding protection components so as to prevent sundries from falling into the expansion joint to influence the normal expansion deformation of the bridge structure, and avoid damage caused by the collision of vehicles on the expansion joint. The existing expansion joint protection structure mostly adopts a cast-in-place concrete shielding plate or a simple metal cover plate, the cast-in-place concrete shielding plate has long construction period, needs a series of procedures of formwork supporting, casting, maintenance and the like, has low construction efficiency and difficult quality control, is not firm in installation, is easy to loosen and fall off under the action of external forces such as vehicle impact, wind blowing and the like, has poor protection effect, cannot adapt to the deformation requirement of an expansion joint, and has short service life.
