Large-span composite PCU cylinder core concrete hollow slab
The invention relates to concrete structure design, in particular to a large-span composite PCU cylinder core concrete hollow slab. The slab comprises a PCU cylinder core (1), a cast-in-place layer (2) and a prefabricated slab (3); the PCU cylinder core (1) is of a hollow structure; the cast-in-place layer (2) is arranged on the prefabricated slab (3); the PCU cylinder core (1) is arranged betweenthe cast-in-place layer (2) and the prefabricated slab (3); closed end plates (11) are arranged at the two ends of the PCU cylinder core (1); and the sizes, located in the cast-in-place layer (2) andthe prefabricated slab (3), of the PCU copper core (1) are same. According to the slab, the problems that in the structural design of an assembled integral floor slab, the thickness of a composite floor slab is large, the structural self-weight is increased, the number of steel bars in the floor slab is increased, the manufacturing cost is increased, and the deflection and cracks of floor slab are not easy to control are solved.
本发明涉及一种混凝土结构设计，具体为一种大跨度叠合式PCU筒芯混凝土空心板，包括PCU筒芯(1)、现浇层(2)和预制板(3)，所述PCU筒芯(1)为空心结构，所述现浇层(2)设在预制板(3)上，所述PCU铜芯(1)设在现浇层(2)和预制板(3)之间，所述PCU筒芯(1)的两端设有封闭端板(11)，所述PCU铜芯(1)位于现浇层(2)和预制板(3)内的体积相同，解决在装配整体式楼板结构设计中，叠合楼板厚度较大，结构自重增加，楼板内钢筋量增加，增加了造价，且不容易控制楼板的挠度和裂缝。
