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 provides a manufacturing method of a fabricated support-free prefabricated ribbed light superposed floor slab, and relates to a manufacturing method of a building floor slab. The method comprises the following steps of: firstly processing bottom longitudinal ribs (or prestressed tendons) and transverse reinforcing steel bars of a prefabricated slab, slab rib longitudinal bars (or prestressed tendons) 3, stirrups 4 or bonding ribs 5 of the prefabricated slab; placing the reinforcing steel bars in a production mold of the prefabricated slab; binding the reinforcing steel bars; casting concrete 6 of a bottom plate of the prefabricating part; putting polyphenyl plates 7 or other light materials in corresponding amount according to requirements; then pouring arris of slab 8; finishing factory processing through curing; in the construction site, hanging the floor slab in place, and then putting the longitudinal and transverse reinforcing steel bars 10 at the upper part of the floor slab; and casting the concrete 11 at the upper part of the floor slab, and curing to finish the support-free prefabricated ribbed light superposed floor slab. By adopting the technology, the slab forms and scaffolding work can be basically eliminated at the construction site; the waste of the building material can be reduced to a maximum extent; the industrial and standardized production of the floor slab can be satisfied; and the integral site assembly of the floor slab can be satisfied.
Description
technical field [0001] The invention relates to a manufacturing method of a building floor, in particular to a manufacturing method of an assembled 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 co...
