AI Technical Summary
The position of the internal mold core of the hollow floor slab is difficult to determine after the concrete is poured, resulting in an irregular floor slab.
The cavity structure, consisting of a bottom woven steel mesh, longitudinal ribs, and transverse stirrups, combined with positioning mechanisms such as L-shaped positioning rods, mounting sleeves, and swing stops, allows for precise positioning of the mold core block by rotating the L-shaped positioning rods and swing stops to adjust its position and ensure alignment of the positioning holes.
It achieves precise positioning of the core blocks within the hollow floor slab, ensuring the neatness of the floor structure and construction quality, shortening the construction period, improving sound insulation, and reducing structural costs.
