The prefabricated slab is easy to realize the industrialization of building components, the manufacturing of the components is not limited by seasons and climate, the quality of the components can be improved, the construction speed is high, a large amount of templates and supports can be saved, but the integrity is poor, the earthquake resistance is not facilitated, and the impermeability is poor. Researchers have come to bear the advent of laminated slabs which combine the advantages of both cast-in-place slabs and precast slabs.
At present, in reinforced concrete buildings, on one hand, the existing concrete composite slabs are common in deformation and crack phenomena and become hot problems of disputes and complaints of the quality of commercial houses, and the existing reinforced concrete buildings not only affect the use function and damage the appearance, but also destroy the whole structure, reduce the rigidity, cause the corrosion of reinforcing steel bars and affect the durability and strength. On the other hand, when an earthquake comes, the prefabricated panels may slide with the brick walls and the ring beams, and if the earthquake intensity is serious, the prefabricated panels are even broken and fall off, and the intensity and the bearing and pressure resistance of the prefabricated panels can not meet the requirements of emerging buildings any more. Along with the economic development of China, the existing laminated slab technology needs a large amount of technology for supporting, the manufacturing process is complex, the installation is troublesome, the manufacturing cost is high, the utilization rate of high-strength steel bars is low, and therefore a laminated slab with simple processing process, convenience in installation and high quality is urgently needed to accelerate the propulsion of assembly type buildings.
Patent CN 207144268U discloses a laminated slab, which comprises a precast slab, a concrete cast-in-situ layer, a stressed steel bar layer and a crossed steel bar network; the two sides of the prefabricated plate are symmetrically provided with occlusion grooves, and the cross section of the prefabricated plate is in a convex structure due to the occlusion grooves; the upper surface of the occlusion groove is provided with a connecting groove, and the adjacent prefabricated plates are connected through installing a groove-shaped steel plate in the connecting groove; the crossed steel bar network is arranged in the occlusion groove at the joint of the adjacent prefabricated plates and comprises first steel bars, second steel bars, third steel bars and fourth steel bars, and the first steel bars, the fourth steel bars, the third steel bars and the second steel bars are alternately distributed along the length direction of the prefabricated plates.
The composite slab disclosed by the patent has the advantages that the crossed steel bar network is arranged in the occlusion groove between the precast slabs, so that the generation of cracks of a concrete cast-in-place layer can be reduced. However, when the first steel bar, the second steel bar, the third steel bar and the fourth steel bar are connected with the channel steel plate, one steel bar needs to be welded or bound, so that the construction process is complex and tedious, the construction time is long, and the integrity of the precast slab and the cast-in-place concrete layer is influenced.
