Abstract

The invention relates to a hollow precast concrete slab which belongs to the technical field of precast reinforced concrete structural members. A plurality of mutually parallel longitudinal through holes are formed in the hollow precast concrete slab along the length direction, transverse grooves intersected with at least one longitudinal through hole are formed in the longitudinal edge at intervals, and slab surface holes for communicating the longitudinal through holes are formed in the slab surfaces on one side or two sides between the transverse grooves. The hollow precast concrete slab provided by the invention can be used in a floor structure and can also be used in the wall body of a multilayer high-rise shear wall building structure and a frame-shear wall building structure, and the hollow precast concrete slab can improve the industrialization level of building structures, perfect the mechanical performance and save resources.

Description

technical field [0001] The invention relates to a prefabricated concrete hollow slab and a manufacturing method thereof, belonging to the technical field of prefabricated reinforced concrete structural components. Background technique [0002] In the construction process of cast-in-place reinforced concrete structures, there are many on-site fabrications and wet operations, and there are a large number of intermediate links such as formwork projects and scaffolding projects, which waste resources and pollute the environment; Issues of building performance, quality and durability. [0003] The main structural components of precast concrete structures are made in factories, which have high production efficiency, good quality, resource saving, and are conducive to sustainable development. The use of precast concrete structures is the development direction of construction industrialization. Prefabricated concrete hollow slabs have low weight, convenient transportation and insta...
