Concrete embedded parts are essential connecting components embedded within structures before the concrete is poured, ensuring integral connectivity and robustness. Dive into the details below for a clearer understanding:
I. Function
The primary role of embedded parts is to offer strategic connection or fixation points, greatly simplifying and securing subsequent installations and constructions. They are extensively implemented in connecting, supporting, and securing prefabricated concrete structures, thereby bolstering the integrity of concrete and ensuring the stability of pipelines and other critical components.
II. Types
1. Steel plate embedded parts: These consist of a robust steel plate accompanied by multiple anchor bars or bolts. The steel plate is meticulously welded with bolts or reinforcing steel. Once integrated into the concrete structure, it becomes a pivotal element for subsequent steel structure welding or equipment installations.
2. Angle steel embedded parts: Crafted from angle steel and anchor bars, these are predominantly utilized in applications requiring angular fixation, such as securing handrails and railings, ensuring precision and stability.
3. C-channel embedded parts: Designed akin to channel steel, these parts are crafted through expert grooving techniques, primarily serving curtain wall systems by facilitating seamless installation of curtain wall hangers.
4. U-channel embedded parts: Complementing bolts or anchor bars, U-channels offer remarkable flexibility in installation and adjustment, making them perfect for integrating irregularly shaped building components.
5. Anchor bolt embedded parts: Comprising robust bolts and anchor bars, these are indispensable for equipment foundations or any application requiring high-strength connections, providing unparalleled stability.
6. Chemical anchor bolts: These unique embedded parts utilize chemical anchoring agents to secure bolts within concrete, ideal for scenarios where supplementary installations might be necessary.
Embedded parts can also be categorized into slot-type and post-installed types based on installation techniques. Slot-type embedded parts ensure reliable installation without compromising concrete and reinforcing steel integrity, making them ideal for components requiring high crack resistance. Conversely, post-installed parts, often secured using chemical anchor bolts, risk damaging concrete, potentially impacting waterproofing and application range.
III. Materials
Embedded parts are usually crafted from carbon steel or stainless steel. The selection of anti-corrosion treatments is tailored to the usage environment, ensuring durability and performance:
1. Carbon steel: This versatile material is apt for general building structures and can be treated with galvanization, spraying, or other anti-corrosion methods to enhance longevity.
2. Stainless steel: Chosen for highly corrosive environments such as chemical plants or coastal areas, it offers superior corrosion resistance and extended service life.
3. Alloy steel: Employed for specialized structures needing high strength, offering superior mechanical properties and reliability.
Additionally, high-strength and corrosion-resistant materials like fiber-reinforced plastic are sometimes used to manufacture embedded parts, ensuring high performance in demanding conditions.
IV. Characteristics
1. Strong load-bearing capacity: Embedded parts, often made from premium materials like high-quality steel and fiber-reinforced plastic, are capable of enduring substantial loads, ensuring structural integrity.
2. Convenient construction: By installing embedded parts before pouring concrete components, the need for specialized tools or techniques is eliminated, streamlining subsequent construction processes and minimizing on-site welding or drilling tasks, thus enhancing efficiency.
3. Flexible adjustment: Certain embedded parts, such as slot-type variants, feature strategically placed slots that enable flexible installation adjustments, effectively resolving force point challenges in suspension systems.
4. Rich design specifications: Diverse design specifications of embedded parts cater to specific application fields like bridge, tunnel, and steel structure engineering, with customization options available for tailored solutions.
5. Good corrosion resistance: Typically constructed from corrosion-resistant materials such as stainless steel, aluminum alloy, and plastic, embedded parts are often treated with galvanization, spraying, or other methods to provide substantial corrosion resistance, ensuring long-term durability.
V. Applications
Embedded parts unquestionably play a pivotal role across a myriad of industries, most notably construction and transportation. Their versatile applications bring forth a host of benefits, including:
1. Prefabricated Concrete Beams: When it comes to prefabricated concrete beams, the inclusion of embedded bolts, steel plates, and other such components not only greatly boosts the load-bearing capacity but also significantly fortifies the structural integrity. This enhancement ensures that the stability of the overall structure is optimally maintained.
2. Bridge Engineering: By incorporating embedded parts, the construction process can be markedly expedited, making the task less arduous while simultaneously augmenting the bridge's load-bearing capacity and overall stability, ensuring long-lasting resilience.
3. Tunnel Engineering: In the realm of tunnel construction, embedded parts are indispensable as they provide robust support for essential elements like signal brackets and cable troughs. These parts are known for their excellent corrosion resistance and formidable load-bearing capacity, delivering unparalleled reliability.
4. Steel Structure Engineering: Within steel structure frameworks, embedded components serve as a crucial reinforcement for the connections between various elements. This reinforcement substantially enhances the overall stability, ensuring the structure's durability and safety.
