Concrete embedded parts are indispensable connecting components meticulously placed within structures before concrete pouring. Discover their remarkable potential:
I. Function
The pivotal role of embedded parts lies in their ability to offer robust connection or fixation points, streamlining subsequent installations and construction. This enhances safety and convenience throughout the entire process. Commonly utilized for the connection, support, and securement of prefabricated concrete structures, these components significantly elevate the connectivity and stability of the concrete while securely anchoring pipelines and various other crucial components.
II. Types
1. Steel plate embedded parts: Crafted with precision, these consist of a steel plate integrated with multiple anchor bars or bolts. The steel plate is expertly welded with bolts or reinforcing steel. Once embedded within the concrete, they serve as critical junctions for subsequent steel structure welds or equipment installations.
2. Angle steel embedded parts: Constructed from angle steel and anchor bars, these parts excel in providing angular fixation, making them ideal for securing structures like handrails and railings with unparalleled stability.
3. C-channel embedded parts: Reminiscent of channel steel, these are ingeniously formed through grooving. They are the backbone of curtain wall systems, facilitating the seamless installation of curtain wall hangers.
4. U-channel embedded parts: These versatile components, when paired with bolts or anchor bars, offer generous installation and adjustment space. They are perfectly suited for accommodating irregularly shaped building components with ease.
5. Anchor bolt embedded parts: Comprising bolts and anchor bars, these parts are indispensable for establishing high-strength connections, especially in equipment foundations and other demanding applications.
6. Chemical anchor bolts: These innovative embedded parts secure bolts within concrete using chemical anchoring agents, proving their worth in scenarios demanding supplementary installations later on.
Moreover, based on the installation method, embedded parts are categorized into slot-type and post-installed embedded parts. Slot-type embedded parts are securely installed without compromising the integrity of the concrete and reinforcing steel, making them perfect for components where crack resistance is paramount. Conversely, post-installed embedded parts, often affixed with chemical anchor bolts, may compromise the concrete's integrity and waterproofing, thus restricting their applicability.
III. Materials
Embedded parts are typically crafted from premium carbon steel or stainless steel. The choice of anti-corrosion treatment depends on the specific environmental conditions:
1. Carbon steel: Widely favored for general building structures, carbon steel can undergo galvanization, spraying, and other anti-corrosion treatments, ensuring long-lasting durability.
2. Stainless steel: Perfect for highly corrosive settings like chemical plants and coastal buildings, stainless steel’s superior corrosion resistance promises an extended service life.
3. Alloy steel: Reserved for special structures demanding exceptional strength, alloy steel boasts remarkable mechanical properties.
Additionally, some embedded parts are crafted from high-strength, corrosion-resistant materials like fiber-reinforced plastic, enhancing their resilience.
IV. Characteristics
1. Strong load-bearing capacity: Engineered from high-grade materials such as premium steel and fiber-reinforced plastic, embedded parts are designed to endure and support substantial loads with ease.
2. Convenient construction: Pre-installed before concrete components are formed, embedded parts eliminate the need for special tools and techniques. This not only streamlines subsequent construction but also minimizes on-site welding or drilling efforts, significantly boosting efficiency.
3. Flexible adjustment: Certain embedded parts, such as slot-type varieties, offer strategic slots positioned at optimal distances from the concrete structure's edge. This flexibility allows for precise adjustment of installation positions, effectively addressing force point challenges in suspension systems.
4. Rich design specifications: Embedded parts come in an array of design specifications tailored to diverse applications, including bridge engineering, tunnel projects, and steel structure endeavors. They can be customized to meet unique requirements with precision.
5. Good corrosion resistance: Typically composed of corrosion-resistant materials like stainless steel, aluminum alloy, or plastic, and often treated with galvanization or spraying, embedded parts exhibit outstanding corrosion resistance and longevity.
V. Applications
Embedded parts, an integral component in the construction and transportation sectors, have a vast array of applications, offering tremendous versatility and reliability:
1. Prefabricated Concrete Beams: Embedded bolts, steel plates, and other elements play a pivotal role in the creation of prefabricated concrete beams, greatly boosting the beams' load-bearing prowess and enhancing the stability of the entire structure.
2. Bridge Engineering: Incorporating embedded parts into bridge engineering projects not only expedites the project timeline but also significantly diminishes construction challenges while enhancing the bridge's load-bearing capabilities and overall stability.
3. Tunnel Engineering: Serving as crucial support structures for signal brackets and cable troughs, embedded parts in tunnel engineering offer excellent corrosion resistance and robust load-bearing capabilities.
4. Steel Structure Engineering: In the realm of steel structure frameworks, embedded parts are essential for fortifying the connections between components, thereby improving the framework's overall stability.
