Non prefabricated safety engineering structure i.e. safety bridge, has reinforced concrete and parallelepiped deck slab that is cast directly, in functional position, in temporary support on ground which is prepared consequently

摘要

The structure has a reinforced concrete and a parallelepiped deck slab (Ta) that is cast directly, in functional position, in temporary support on the ground which is prepared consequently. The slab has vertical support pillars (M) at ends and at its mid length, where the pillars are in reinforced concrete. The pillars are constructed by ground-work for protection against collapse. An independent claim is also included for a method for constructing a non prefabricated safety engineering structure.
