Embodiment 1

[0038] Embodiment 1 is a kind of prefabricated reinforced concrete slab member, as figure 1 , figure 2 As shown, the prefabricated component 1 is provided with a number of longitudinal through holes 2 parallel to each other along the length direction, and a number of parallel horizontal non-through holes 3 are opened along the width direction, and the horizontal holes communicate with at least one longitudinal hole; the prefabricated component 1 is provided with installation suspension ring 5. The cross-section of the longitudinal hole is circular, rectangular, etc., and the diameter or side length is 60mm to 340mm. The cross-section of the transverse non-through hole is circular, rectangular, etc., and the rectangle is a better cross-section. The diameter or side length of the transverse hole is 20mm different from that of the longitudinal hole; Twice as much as requested. When prefabricated reinforced concrete slab members are used as walls, the length is generally taken...

Abstract

The invention relates to a precast concrete hollow component, and a manufacturing method thereof, and belongs to the technical field of precast reinforced concrete structural components. The precast concrete hollow component comprises a precast wall plate component, a floor component, a T-shaped wall post component, an L-shaped wall post component, a cross wall post component and a wall body component provided with a hole; the precast concrete hollow component is internally provided with a plurality of longitudinal through holes along the length direction, and a plurality of horizontal non-through holes communicated with the longitudinal through holes along the width direction, wherein the longitudinal through holes are arranged parallelly to each other, and the horizontal non-through holes are arranged parallelly to each other. The manufacturing method comprises following steps: combining templates, such as a bottom die, a top die, a side die, a steel pipe inner die and the like, on a production field of precast slabs; arranging reinforcing meshes; then pouring concrete; drawing out a steel pipe after the strength of the concrete reaches to a certain degree; and dismounting the templates after the concrete reaches to an expected strength degree. The precast concrete hollow component can be used in multilayered, high-rise shear wall and frame-shear wall building structures, thus improving industrial level of the building structures, improving structural behaviors and saving sources.

Description

technical field [0001] The invention relates to a prefabricated concrete hollow component 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 components have low weight, convenient transportation...
