FIELD: construction.
SUBSTANCE: invention is attributed to design of prefabricated reinforcement cages used in various building structures: sealing slabs and wall slabs, as well as in road, industrial and civil construction, namely to reinforced slabs design. Proposed prefabricated reinforcement cage is high-technology solution for both production and assembling in situ. The technical result is achieved due to the fact that prefabricated reinforcement cage contains reinforcing rods positioned with bias along edges of tetrahedrons with tops pointing in opposite directions, Each tetrahedron formed by rods has reinforcement rods common for adjacent sides and corner elements fitted at its top made in the form of cylinders with holes in side surface, where ends of reinforcement rods positioned with bias are fitted. Reinforcement rods can have bent ends, holes of corner elements being located radially. At least part of corner elements is furnished with axial hole interconnected with holes for reinforcement rods fitting or with frontal threaded projections for flanges. Additionally, reinforcement rods and/or corner elements can be made of fiberglass.
EFFECT: stiffening of prefabricated reinforcement cage and possibility to improve bearing capacity of building structures.
