Abstract

The invention relates to a prefabricated concrete hollow member and a preparation method thereof, and belongs to the technical field of prefabricated reinforced concrete structure members. The prefabricated concrete hollow member comprises a prefabricated panel member, a floorslab member, a T-shaped wall column member, an L-shaped wall column member, a cross-shaped wall column member and a wall member with holes. The wall member with the holes comprises the holes, a coupling beam at the upper portion of the holes and walls on two sides of each hole. Multiple communicated and longitudinal holes are arranged in the prefabricated concrete hollow member along the length direction and are parallel to each other, and multiple non-through horizontal holes are arranged in the prefabricated concrete hollow member along the width direction. Board holes are arranged at the joints of the longitudinal holes and the horizontal holes. The prefabricated concrete hollow member can be applied in a multi-storey and high-rise shear wall building structure and a framework-shear wall construction wall, and therefore industrialization level of a building structure can be improved, stress property is improved, and resource is saved.

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...
