Abstract
An integrally assembled hidden beam hollow two-way floor system includes precast slabs (1), honeycomb steel beams (3), and cast-in-place concrete (4). A plurality of compartments (12) arranged in a matrix is integrally provided on one surface of each of the precast slabs (1), and connecting grooves (14) are provided at a periphery of another surface of the precast slab (1) is provided with connecting grooves (14). Prepared bolt holes (13) penetrating through the precast slab (1) are provided in the connecting grooves (14). The honeycomb steel beam (3) serves as a primary beam or a secondary beam of a steel structure of the floor system. A surface of the precast slab (1) provided with no compartments is lapped and fixed between the secondary beams or between the primary beam and the secondary beam, and adjacent precast slabs (1) are connected and fixed by a U-shaped hoop (2) passing through the prepared bolt hole (13) to form a seam. The cast-in-place concrete (4) includes a surface layer cast onto the compartments (12) and a cast-in-place concrete ribs (41) cast between the compartments (12) of adjacent precast slabs (1) and between the compartment (12) and the primary beam and the…
