Round Head Lifting Nails for Lifting Embedded Parts of Building Accessories¹

Product Description Hanging nails are fasteners used as embedded parts in prefabricated buildings, mainly for connecting and fixing prefabricated components to ensure stability and safety during the lifting process. The following is a detailed description of the hanging nail:1, Basic functionsHanging nails are embedded inside prefabricated components to provide connection points for lifting. During the lifting process, the hanging nails can withstand the weight of prefabricated components and safely and stably lift them to the designated position.2, Main typesAccording to different structures and purposes, hanging nails can be divided into various types, among which the more common ones are:1. Round head hanging nail: The round head hanging nail is fixed on the concrete surface through a hemispherical sleeve, and the lifting load is transmitted to the concrete by the circular fixed end anchor at the other end of the hanging nail. It is suitable for conventional residential prefabricated components and industrial buildings, and has the characteristic of fast lifting.2. Threaded hanging nails: The installation and fixation of threaded hanging nails are relatively simple, and they can usually be directly anchored in concrete without the need for special grooves. During lifting, construction personnel can screw the external threaded lifting device into the nail sleeve to achieve connection.3. Flat hanging nails: Flat hanging nails are made by processing steel plates, with the bottom steel plate anchored inside the concrete, and the exposed steel plate connected to a dedicated lifting device through end holes. It is suitable for lifting system wall panels and other occasions.3, Material and CraftsmanshipHanging nails are usually made of high-strength steel to ensure that they can withstand the weight of prefabricated components. In terms of manufacturing process, hanging nails often use processes such as red stamping and hot forging to improve their strength and toughness. At the same time, surface treatment of hanging nails is also important, and common treatment methods include sandblasting, galvanizing, etc., to improve their corrosion resistance and aesthetics.4, Specifications and Load CapacityThe specifications of hanging nails include parameters such as diameter, length, and load-bearing capacity, and the selection of these parameters needs to be determined based on the weight, shape, and lifting requirements of the prefabricated components. For example, the maximum load capacity of a single round head hanging nail can reach 32 tons, but the specific selection still needs to consider factors such as concrete strength and hanging point layout.5, Precautions for use1. Reasonable arrangement of lifting points: When arranging lifting points on prefabricated components, it is necessary to ensure that the lifting nails are evenly distributed to avoid excessive stress concentration during the lifting process.2. Proper installation of hanging nails: The installation of hanging nails should comply with relevant standards and specifications to ensure a firm connection with the concrete. During the installation process, specialized installation tools should be used for fastening, and the position and connection of the hanging nails should be checked.3. Choose appropriate lifting methods and equipment: Based on the weight and shape of prefabricated components, select appropriate lifting methods and equipment to ensure the safety and stability of the lifting process.4. Conduct load-bearing capacity testing: When necessary, load-bearing capacity testing should be conducted on the hanging nails to verify their safety performance.6, Application scenariosHanging nails are widely used in the field of prefabricated construction, such as the lifting of prefabricated wall panels, prefabricated stairs, prefabricated beams, prefabricated columns and other components. By embedding hanging nails, quick connection and fixation of prefabricated components can be achieved, improving construction efficiency and quality.
