Assembled composite floor slab and manufacturing method thereof
The invention relates to an assembled composite floor slab and a manufacturing method thereof. The assembled composite floor slab comprises II-shaped precast slabs (2), a plurality of I-shaped precast slabs (1) and a post-cast lightweight aggregate concrete layer (3), the II-shaped precast slabs (2) are positioned on two sides, the I-shaped precast slabs (1) are arranged between the two II-shaped precast slabs (2), and the post-cast lightweight aggregate concrete layer (3) is cast above the I-shaped precast slabs (1) and the II-shaped precast slabs (2) and between joint cracks. Compared with the prior art, the assembled composite floor slab has the advantages that the weight of the assembled composite floor slab is lighter as compared with an existing floor slab structure, the large-size precast slabs are used, assembled construction is performed, on-site wet construction quantity is the least, construction period is short, concrete wraps primary and secondary steel girders, overall fire resistance and corrosion resistance of the floor slab are improved, the upper surface and the lower surface of the floor slab are flat, and the assembled composite floor slab has an excellent appearance.
