Embodiment

[0026] Example: The cast-in-place thickness of the cast-in-place roof slab is 50-100mm, the thickness of the prefabricated slab bottom is 60-100mm, the size of the middle foam box is 500x500-900x900mm, the longitudinal rib width is 150-200mm, and the transverse rib width is 150-200mm. 150~200mm wide. During the construction process, the bottom formwork of the floor slab is formed by prefabricating the bottom slab and the middle foam box. After the upper steel bars are installed, concrete is poured to form a densely ribbed floor slab. Most of the concrete at the tension point is removed. The shaped beam bears the vertical load, and the force is more reasonable, which greatly reduces the self-weight of the floor and saves materials such as formwork, steel bars and concrete.

Abstract

A laminated assembly type concrete ribbed floor comprises a prefabricated base plate and a top plate which is an on-site casted top plate with ribbed beams, and the base plate and the top plate are assembled in a laminated manner. Longitudinal and lateral construction steel ribs are arranged in the prefabricated base plate, and longitudinal and lateral top plate construction steel ribs are arranged in the on-site casted top plate. The ribbed beams comprise lateral ribbed beams and longitudinal ribbed beams, and ribbed beam top reinforcing ribs, ribbed beam bottom reinforcing ribs and ribbed beam stirrups are arranged in the ribbed beams. Hollow boxes or light material bodies are filled in the space between the ribbed beams. Erecting and dismounting of templates and associated tool type supporting systems are not needed, thereby lowering cost, improving efficiency, saving construction materials, and reducing the dead weight. Force bearing is more reasonable, the structural strength is high, and the quality is good.

Description

technical field [0001] The invention belongs to the technical field of construction engineering, and in particular relates to a superimposed and assembled concrete ribbed floor slab. Background technique [0002] The fully cast-in-place concrete hollow-core slab has the advantages of saving building materials, reducing self-weight, good integrity, and high structural strength. However, the fully cast-in-place concrete hollow floor slab requires a large number of supporting and folding formwork and supporting tool-type support systems. The amount of work is large and the operation is complicated. Generally, specialized wooden formwork technicians are required. There are many formwork, high cost, and long construction period. Finally, it is time-consuming and labor-intensive to remove the formwork. At the same time, the thickness of the lower flange of the fully cast-in-place concrete hollow floor slab is relatively thin. When pouring concrete, the lower flange is prone to ai...
