Hanging nails are indispensable fasteners, widely recognized for their crucial role as embedded parts in the realm of prefabricated buildings. Primarily serving to connect and secure prefabricated components, they ensure unparalleled stability and safety throughout the entire lifting process. Dive into the comprehensive exploration of the hanging nail:
1, Basic functions
Hanging nails, embedded within prefabricated components, create robust connection points for lifting operations. These nails are engineered to adeptly manage the weight of prefabricated elements, allowing for their safe and stable elevation to designated positions with absolute reliability.
2, Main types
Boasting diverse structures and purposes, hanging nails can be categorized into various types, with the most prevalent ones being:
1. Round head hanging nail: Ingeniously fixed on the concrete surface via a hemispherical sleeve, the round head hanging nail transmits lifting loads through a circular fixed-end anchor. Ideal for conventional residential and industrial prefabricated components, it offers the advantage of swift lifting.
2. Threaded hanging nails: Threaded hanging nails are celebrated for their straightforward installation and fixation, as they can anchor directly into concrete without specialized grooves. During lifting, workers can seamlessly screw an external threaded lifting device into the nail sleeve for a secure connection.
3. Flat hanging nails: Crafted from processed steel plates, flat hanging nails feature a bottom steel plate anchored within the concrete and an exposed steel plate linked to a dedicated lifting device via end holes. Perfect for lifting system wall panels and similar applications.
3, Material and Craftsmanship
Forged from high-strength steel, hanging nails are designed to withstand the hefty weight of prefabricated components. Manufacturing processes such as red stamping and hot forging enhance their strength and toughness. Additionally, surface treatments like sandblasting and galvanizing are crucial to bolstering corrosion resistance and aesthetic appeal.
4, Specifications and Load Capacity
Hanging nail specifications encompass parameters like diameter, length, and load-bearing capacity, which must be tailored to the weight, shape, and lifting demands of the components. For instance, a single round head hanging nail boasts a maximum load capacity of 32 tons, yet the choice must factor in concrete strength and hanging point layout.
5, Precautions for use
1. Reasonable arrangement of lifting points: Ensuring a balanced distribution of lifting nails on prefabricated components is vital to mitigate stress concentration during lifting.
2. Proper installation of hanging nails: Compliance with relevant standards and specifications during installation is essential for a secure connection with concrete. Utilize specialized tools for fastening, and verify the position and connection of the hanging nails rigorously.
3. Choose appropriate lifting methods and equipment: Select lifting methods and equipment based on the weight and shape of prefabricated components to guarantee safety and stability.
4. Conduct load-bearing capacity testing: Conduct testing, as needed, to confirm the safety performance of the hanging nails.
6, Application scenarios
Hanging nails are a cornerstone in prefabricated construction, extensively utilized for lifting prefabricated wall panels, stairs, beams, columns, and more. By embedding hanging nails, swift connection and fixation of prefabricated components are achieved, significantly elevating construction efficiency and quality.
