Embodiment Construction
[0014] Such as figure 1 and figure 2 As shown, the novel large-span hollow self-insulating floor of the present invention adds a reinforced concrete floor on the basis of the traditional well-shaped floor to form a hollow floor structure with a flat bottom. Several prefabricated floor slabs are spliced and assembled through vertical and horizontal two-way concrete post-casting connection belts. A single floor slab has an integrally prefabricated top slab, bottom slab, and longitudinal and horizontal rib beams in the middle, and reserved steel bars protrude around the slab.
[0015] The prefabricated floor slab includes a top slab 1, a bottom slab 2, a number of well-shaped intersecting rib beams 3, and thermal insulation and sound insulation fillers 4; The directions are arranged at equal distances, and the thermal insulation and sound insulation fillers 4 are arranged between the rib beams 3 and fill up the gaps between the rib beams 3 .
[0016] The top slab 1, bottom s...
