Pre-embedded parts, also known as prefabricated embedded components, are ingeniously integrated into the foundation or structural framework during the construction phase. Below is an elaborate elucidation on these pivotal embedded parts:
1. Definition and Purpose
Pre-embedded parts are strategically installed within concealed works or structures during the structural pouring process. Their primary role is to facilitate seamless overlapping in the construction of superstructures, as well as ensuring the precise installation and secure anchoring of external engineering equipment foundations. These components are instrumental in propelling subsequent construction phases smoothly and significantly enhance the stability and safety of the entire structure.
2. Material and Type
The majority of embedded parts are crafted from robust metals like steel bars or cast iron, although non-metallic rigid materials such as wood and plastic are also utilized. Typical types of embedded parts encompass concrete embedded parts, curtain wall embedded parts, Hafen groove embedded parts, embedded pipes, embedded bolts, bridge embedded parts, street lamp embedded parts, embedded steel plates, among others.
3. Function and Advantages
1. Connection Function: Embedded parts serve as steadfast linkages that amalgamate various structural components or equipment into a unified entity.
2. Fixed Function: Prior to concrete pouring, these parts are deftly embedded to secure components like wall panels, ladders, and pipes firmly in place.
3. Supporting Function: They offer sturdy support points, ensuring the structural stability when subjected to external forces.
4. Bearing Capacity: With optimal design and strategic arrangement, embedded parts significantly bolster the structure's load-bearing capacity.
5. Seismic Resistance: Embedded parts also fortify the seismic resilience of structures, enhancing overall safety.
4. Application Scenarios
Pre-embedded parts find extensive application across diverse construction ventures, including high-rise buildings, bridges, tunnels, and subways. In curtain wall engineering, these parts are crucial in linking the curtain wall to the main structure, where the quality of their connections directly impacts the curtain wall's structural integrity and longevity.
In conclusion, embedded parts are indispensable in construction engineering. By being pre-installed and buried, they provide steadfast connections, secure fixation, reliable support, and enhanced load-bearing points for ongoing construction processes, thereby safeguarding the stability and integrity of the entire structure.
