Hanging nails, a quintessential element in the world of construction, serve as indispensable fasteners designed to be embedded in prefabricated buildings. These robust connectors play a pivotal role in securely joining and stabilizing prefabricated components, ensuring unwavering stability and unwavering safety during the critical lifting process. Delve into the intricate details of the hanging nail:
1, Basic Functions
Embedded within the heart of prefabricated components, hanging nails establish steadfast connection points that shoulder the weight of these components during the lifting process. They ensure a seamless and secure elevation to designated positions, offering both peace of mind and precision.
2, Main Types
Hanging nails are as diverse as they are essential, classified by structure and purpose into several types. Among these, the most prevalent varieties include:
1. Round head hanging nail: This type is ingeniously secured on concrete surfaces using a hemispherical sleeve, transmitting the lifting load efficiently through a circular fixed end anchor. It is ideally suited for conventional residential prefabricated components and industrial constructions, known for its rapid lifting capabilities.
2. Threaded hanging nails: Renowned for their simplicity, these nails can be seamlessly anchored into concrete without the necessity for specialized grooves. During lifting, a threaded lifting device can be effortlessly screwed into the nail sleeve, achieving a flawless connection.
3. Flat hanging nails: Crafted from robust steel plates, these nails feature a bottom steel plate anchored within concrete and an exposed plate connected to a specialized lifting device via end holes. Perfect for lifting system wall panels and similar applications.
3, Material and Craftsmanship
Crafted from high-strength steel, hanging nails are engineered to endure the formidable weight of prefabricated components. Advanced manufacturing processes like red stamping and hot forging enhance their strength and resilience. Surface treatment methods such as sandblasting and galvanizing are employed to augment their corrosion resistance and visual appeal.
4, Specifications and Load Capacity
With specifications encompassing diameter, length, and load-bearing capacity, hanging nails are meticulously selected based on the unique weight, shape, and lifting requirements of prefabricated components. For instance, a single round head hanging nail boasts a maximum load capacity of 32 tons, though individual selections must consider concrete strength and hanging point distribution.
5, Precautions for Use
1. Reasonable arrangement of lifting points: Ensure an even distribution of lifting nails on prefabricated components to prevent excessive stress concentration during lifting, safeguarding the components' integrity.
2. Proper installation of hanging nails: Adhere to relevant standards and specifications during installation to guarantee a robust connection with concrete. Employ specialized tools, ensuring precise positioning and secure connections.
3. Choose appropriate lifting methods and equipment: Tailor your choice of lifting methods and equipment to suit the weight and shape of prefabricated components, ensuring a safe and stable lifting process.
4. Conduct load-bearing capacity testing: As a precaution, conduct load-bearing capacity tests on hanging nails when necessary to verify their safety performance, ensuring optimal security.
6, Application Scenarios
Widely embraced in the realm of prefabricated construction, hanging nails facilitate the lifting of prefabricated wall panels, stairs, beams, columns, and more. By seamlessly embedding hanging nails, swift connection and fixation of prefabricated components are achieved, enhancing construction efficiency and elevating quality standards.
