Hanging nails are essential fasteners designed to be used as embedded components within prefabricated buildings. They play a crucial role in linking and securing prefabricated parts, thereby guaranteeing stability and safety throughout the lifting process. Below, we provide an in-depth look at the functionalities and benefits of these remarkable hanging nails:
1. Basic Functions
These hanging nails are strategically embedded within prefabricated components, serving as pivotal connection points for lifting. Engineered to withstand the heft of these components, they ensure a safe and steady elevation to the required location.
2. Main Types
Hanging nails come in a variety of designs and fulfill different purposes based on their structure. Here are some of the most prevalent types:
1. Round Head Hanging Nail: This type is secured to concrete surfaces through a spherical sleeve, transferring the lifting load via a circular fixed end anchor. It's ideal for traditional residential and industrial prefabricated components, known for its rapid lifting efficiency.
2. Threaded Hanging Nails: Known for their straightforward installation, these nails can be directly anchored into concrete without special grooves. During lifting, workers can seamlessly screw the external threaded lifting device into the nail sleeve for secure attachment.
3. Flat Hanging Nails: Crafted from processed steel plates, these nails feature a base plate anchored inside concrete, with an exposed plate connected to specific lifting devices via end holes. They are perfect for lifting system wall panels and similar applications.
3. Material and Craftsmanship
Hanging nails boast high-strength steel construction to endure the weight of prefabricated elements. Techniques like red stamping and hot forging are employed to augment their strength and durability. Surface treatments such as sandblasting and galvanizing enhance corrosion resistance and aesthetics.
4. Specifications and Load Capacity
Specifications of hanging nails include diameter, length, and load-bearing capability, all of which should align with the weight, shape, and lifting stipulations of the prefabricated parts. For instance, a single round head hanging nail can support up to 32 tons, but choices should factor in concrete strength and lifting point configuration.
5. Precautions for Use
1. Strategic Lifting Point Arrangement: Ensure lifting nails are evenly distributed on prefabricated components to prevent stress concentration during lifting.
2. Proper Installation: Follow industry standards for securing hanging nails in concrete, using specialized tools for connection and verifying nail positioning and linkage.
3. Selecting Suitable Lifting Methods and Equipment: Consider the weight and form of prefabricated parts to choose apt lifting strategies and gear, assuring a secure and stable lifting operation.
4. Conduct Load-Bearing Tests: Perform load capacity testing on hanging nails when necessary to confirm their safety performance.
6. Application Scenarios
Hanging nails are extensively utilized in prefabricated construction, including the elevation of wall panels, stairs, beams, columns, and more. By embedding these nails, rapid connection and stabilization of prefabricated components are achieved, significantly boosting construction efficiency and quality.
