Description

[0001] This utility model relates to the field of communication pipeline laying technology, specifically to a PC component for prefabricated buildings. Background Technology

[0002] Prefabricated construction refers to transferring a large amount of on-site work from traditional construction methods to factories. Building components and accessories (such as floor slabs, wall panels, stairs, balconies, etc.) are prefabricated in factories, transported to the construction site, and assembled on-site using reliable connection methods. However, some components are easily damaged during transportation due to stress, such as floor slabs with doors and windows. Uneven overall structure leads to varying stress levels, resulting in structural instability and susceptibility to damage. Traditional prefabricated PC components have the following drawbacks: complex connections requiring on-site welding or grouting; low construction efficiency and reliance on manual labor for quality; susceptibility to damage during transportation, with component edges easily bumped and damaged, leading to decreased installation accuracy; unstable hoisting, with improperly designed hoisting points causing component tilting or cracking; and poor adaptability, unable to quickly adapt to adjacent components of different sizes.
