FIELD: construction.
SUBSTANCE: invention relates to the field of construction and can be used in the production of hollow-core slabs with a technological opening intended for the passage of utilities. Design of the plate consists of two solid bodies, hollow and solid cross-sections, with concrete and rebar dowels combined into a single unit. Solid body of the plate at a distance of 250…350 mm from the end of the opening diameter of posted 600…700 mm, is reinforced by the individual contour rods arranged in the upper part of the section.
EFFECT: technical result is to increase the functionality and performance of the hollow-core slabs by devices in the process plate opening.
