Embodiment Construction
[0023] The present invention will be described in detail below in conjunction with the embodiments shown in the accompanying drawings.
[0024] Assembled support-free prefabricated ribbed lightweight (prestressed) laminated slab is a new type of floor slab that first processes the lower components of the slab in the factory, and then binds the upper reinforcement of the slab and pours the upper concrete of the slab at the construction site to form an integral slab. Prefabricated composite floor form. Since the polystyrene board (or other lightweight building materials) is used as a substitute for most of the concrete that does not contribute to the overall floor force, the self-weight and reinforcement of the floor are greatly reduced, and the one-way or two-way slab ribs are effectively improved. In addition to the rigidity of the laminated slab, it also solves the problem of shear resistance of the new and old concrete laminated surfaces; this technology can also use prestre...

The invention relates to a building floor slab, in particular to an assembled supporting-free prefabricated light composite floor slab with ribs. Longitudinal steel bars (or prestressed steel bars) and transverse steel bars are arranged at the bottom of a prefabricated slab, and prefabricated slab rib longitudinal bars (or prestressed steel bars) and stirrups or Rachel bars are further arranged at the bottom of the prefabricated slab, the steel bars are placed in a production mold of the prefabricated slab, construction members are bound with the steel bars, concrete is molded, polyphenyl plates or other light materials are placed on the concrete, plate ribs are poured, and the prefabricated portion of the supporting-free prefabricated light composite floor slab with ribs is produced; and the floor slab of the prefabricated portion is hoisted in place on site, the longitudinal steel bars and the transverse steel bars which are arranged on the upper portion of the floor slab are placed on the prefabricated portion, the concrete arranged on the upper portion of the floor slab is poured, and the supporting-free prefabricated light composite floor slab with ribs is produced. By adopting the supporting-free prefabricated light composite floor slab with ribs, the floor slab template and scaffolding work on the construction site can be basically omitted, construction material waste can be reduced in the maximum limit, floor slab industrialized production and standardized production requirements of plants can be met, and floor slab integral on-site assembly can be achieved.
Description
technical field [0001] The invention relates to a building floor, in particular to an assembly-type support-free prefabricated ribbed lightweight laminated floor. Background technique [0002] The cast-in-place (referred to as cast-in-place) reinforced concrete building structure requires a large material stacking and material processing site and a large amount of labor input because its steel bar processing, binding, formwork production and support, concrete pouring and curing molding are all completed on the construction site , Therefore, each process in the construction often interferes with each other, the construction quality is not easy to guarantee, and there is a large amount of wet work on site, and the accumulation of construction waste seriously affects the construction site and the surrounding environment, causing environmental pollution. [0003] In recent years, due to the increasingly tense use of land in the country, the use of land by builders is getting hi...
