Concrete embedded parts are the essential connectors integrated into structures before the concrete pour. Let's dive into a deeper understanding:
I. Function
The primary role of embedded parts is to provide sturdy connection or secure fixation points for future installations, ensuring the entire process is seamless, safe, and efficient. These components are vital in the connection, support, and securing of prefabricated concrete structures, enhancing connectivity and securing pipelines as well as other integral components, fortifying the entire structural network.
II. Types
1. Steel plate embedded parts: These consist of a steel plate adorned with multiple anchoring bars or bolts. The steel plate is typically welded with bolts or reinforcing steel, and once embedded in the concrete, it facilitates future steel structure welding or equipment installation.
2. Angle steel embedded parts: Crafted from angle steel and anchor bars, these parts serve perfectly for applications requiring angular fixation, such as handrails and railings, ensuring stability and precision.
3. C-channel embedded parts: Resembling channel steel, these are innovative components shaped through grooving, predominantly utilized in curtain wall systems, streamlining the installation of curtain wall hangers.
4. U-channel embedded parts: Designed to be used with bolts or anchor bars, U-channels offer versatile installation and adjustment capabilities, ideal for complex and irregularly shaped building components.
5. Anchor bolt embedded parts: Featuring a composition of bolts and anchor bars, they are ideal for equipment foundations or other areas demanding high-strength connections, ensuring reliable performance.
6. Chemical anchor bolts: These innovative embedded parts utilize chemical anchoring agents to secure bolts in concrete, perfect for scenarios requiring post-construction installations.
Furthermore, embedded parts can be classified based on installation methods into slot-type embedded parts and post-installed embedded parts. Slot-type parts ensure a robust installation without harming the concrete or reinforcing steel, suitable for applications with high crack-resistance requirements. In contrast, post-installed parts, secured with chemical anchor bolts, may compromise concrete integrity and waterproof capabilities, thus limiting their usage in certain applications.
III. Materials
Typically, embedded parts are constructed from carbon steel or stainless steel, with anti-corrosion treatments selected based on their intended environment:
1. Carbon steel: Often preferred for general construction, it can undergo galvanization, spraying, and other anti-corrosion procedures to enhance durability.
2. Stainless steel: Ideal for highly corrosive environments like chemical plants or coastal areas, this material boasts superior corrosion resistance and extended longevity.
3. Alloy steel: Employed in special structures or applications demanding high strength, offering superior mechanical properties for exceptional durability.
Moreover, in some cases, embedded parts may be crafted from high-strength, corrosion-resistant materials such as fiber-reinforced plastic, ensuring peak performance even in challenging conditions.
IV. Characteristics
1. Strong load-bearing capacity: Constructed from high-strength materials like premium steel and fiber-reinforced plastic, embedded parts are engineered to endure substantial loads without compromising integrity.
2. Convenient construction: Installed prior to concrete formation, embedded parts eliminate the need for specialized tools or techniques, simplifying subsequent construction phases, reducing the necessity for on-site welding or drilling, and enhancing overall construction efficiency.
3. Flexible adjustment: Some embedded parts, such as slot-type, feature adaptable slots that allow flexible positioning within the concrete structure, expertly addressing force point challenges in suspension systems.
4. Rich design specifications: Embedded parts cater to various design specifications across diverse fields such as bridge, tunnel, and steel structure engineering, allowing customization to meet specific project needs.
5. Good corrosion resistance: Crafted from materials like stainless steel, aluminum alloy, and plastic, or treated with galvanization, spraying, and other methods, embedded parts are designed to offer excellent corrosion resistance, ensuring long-lasting performance.
V. Applications
Embedded parts boast versatile applications spanning a multitude of sectors, notably construction and transportation. Their utilization in these areas is both diverse and impactful:
1. Prefabricated Concrete Beams: The incorporation of embedded bolts, steel plates, and other embedded components is pivotal in crafting prefabricated concrete beams. This significantly elevates the load-bearing prowess and fortifies the structural integrity of the beams, thereby enhancing the stability of the entire construction.
2. Bridge Engineering: Embedded parts play a crucial role in streamlining project timelines and simplifying construction processes. They are instrumental in bolstering the load-bearing capacity and ensuring the enduring stability of bridges, thereby contributing to safer and more reliable infrastructure.
3. Tunnel Engineering: Serving as robust support structures, embedded parts in tunnel engineering facilitate the installation of signal brackets and cable troughs. They offer exceptional corrosion resistance and superior load-bearing capacity, making them indispensable for enduring tunnel projects.
4. Steel Structure Engineering: Within the realm of steel structure frameworks, embedded parts are essential for reinforcing connectivity between components. This enhancement leads to heightened stability and ensures the resilience of the overall structural framework.
