EATHU Lifting Pin Anchor: Top Choice for Prefabricated Building Construction | High-Quality Embedded Parts
I. Product Overview
Lifting pin anchors are essential embedded parts in prefabricated buildings, shouldering the crucial mission of lifting various prefabricated components. In the current era of the booming development of prefabricated buildings, their application scenarios are constantly expanding, and their significance is becoming increasingly prominent. They are extensively utilized in diverse construction fields, including residential buildings, commercial complexes, industrial plants, and bridges. Whether for prefabricated beams and columns of the building's main structure or non - structural components such as decorative hanging panels and lightweight partition walls, lifting pin anchors ensure that prefabricated components can be accurately and safely lifted and installed in their designated positions.
II. Manufacturing Process
Materials：Lifting pin anchors primarily use 20mn2A as the fundamental raw material. 20mn2A is a high - quality carbon structural steel featuring a moderate carbon content. The addition of manganese elements further enhances its strength and toughness. This material endows the lifting pin anchors with high tensile strength, along with good plasticity and cold - deformation capabilities. In complex lifting operation environments, they can effectively withstand impact loads and are less prone to brittle fracture. For certain special projects with extremely high demands on the performance of lifting pin anchors, alloy steel materials like 40Cr and 35CrMo are employed. These alloy steels, with the incorporation of alloying elements such as chromium and molybdenum, significantly improve the comprehensive mechanical properties of the lifting pin anchors, including strength, hardness, wear resistance, and corrosion resistance. This makes them suitable for large - scale bridges, high - rise buildings, and other projects with stringent safety requirements.
Processing Technology：The red punching and forging process is adopted for manufacturing. Red punching and forging is a processing method that applies pressure to a metal blank through a mold at high temperatures, causing it to undergo plastic deformation to obtain the desired shape and size. During the manufacturing of lifting pin anchors, red punching and forging can refine the metal grains, rendering the internal structure denser and more uniform, and eliminating internal defects. This significantly improves the mechanical properties of the lifting pin anchors. Compared with other processes such as cold heading, lifting pin anchors produced by red punching and forging possess higher strength and better toughness, and can endure greater tensile and impact forces, providing a solid guarantee for the safety of lifting operations.
Surface Treatment：The common surface treatment method is sandblasting. By using high - speed - sprayed sand grains to impact the surface of the lifting pin anchors, oxide scales and impurities are removed, the surface roughness is increased, and the friction with other components is enhanced, ensuring a more stable connection of the lifting pin anchors during the lifting process. Some lifting pin anchors are galvanized. The galvanized layer acts as a protective film, which can remarkably improve the anti - rust ability of the lifting pin anchors and extend their service life, especially suitable for humid or corrosive environments. In some projects with extremely high requirements for appearance and corrosion prevention, surface treatment processes such as chrome plating and nickel plating are also utilized. Chrome - plated lifting pin anchors have high surface hardness, good wear resistance, and an appealing metallic luster. The nickel - plated layer can effectively enhance the corrosion resistance and oxidation resistance of the lifting pin anchors, making them suitable for construction projects in corrosive environments such as marine areas and chemical industrial parks.
Packaging and Transportation：The packaging typically takes the form of bags, which is convenient for handling, storage, and counting. During transportation, appropriate logistics methods are selected based on the order quantity and customer requirements to ensure that the products are safely and promptly delivered to the construction site.
III. Product Advantages
Advantages in the Production Process：Prefabricated buildings adopt the factory - prefabricated component model, and lifting pin anchors play an auxiliary role in production. Factory production is not affected by adverse weather conditions, avoiding construction delays caused by weather in traditional construction, thus making the construction period more manageable. Simultaneously, the standardized and large - scale production process, combined with the precise application of lifting pin anchors, significantly boosts production efficiency.
Improvement of Building Quality：The precision of prefabricated buildings can reach the millimeter level. As key components for precise lifting, lifting pin anchors ensure the accurate positioning of prefabricated components during lifting and installation, making the connection of various components closer and reducing errors. This enhances the overall quality of the building. For instance, the walls are more planar, and the installation of doors and windows is more precise.
Optimization of Manpower and Cost：It reduces the heavy reliance on a large number of on - site workers in construction. Lifting pin anchors, in combination with the lifting of prefabricated components, decrease on - site wet construction work, reduce the number of on - site construction workers, ease the labor shortage problem, and cut down on labor costs.
Energy - Saving and Environmental - Protection Features：The on - site installation of components reduces wet construction work, such as concrete pouring and plastering, thereby reducing the generation of construction waste and dust pollution. Factory - based production can optimize the utilization of raw materials and improve resource utilization efficiency, which is in line with the development trend of green buildings.
Enhancement of Structural Performance：Prefabricated buildings demonstrate excellent seismic performance with their unique connection technologies and component designs. As important components for lifting prefabricated components, lifting pin anchors, with their reliable connection and load - bearing capacity, ensure the structural stability of buildings during earthquakes, effectively absorbing and dispersing seismic energy and safeguarding lives and property.
Improvement of Space Utilization：Due to the high precision of prefabricated building components, the wall thickness is relatively thinner. During the lifting and installation process of lifting pin anchors, precise construction is facilitated, increasing the indoor usable area under the same floor area and improving space utilization.
IV. Supporting Products
Wave - shaped Rubber (Wave Glue)：Made of rubber, it is hemispherical with cracks and is equipped with a screw rod. During construction, it is sleeved on the small head of the lifting pin anchor to create space for the lifting operation and protect the connection between the lifting pin anchor and the component. The optimal wave - shaped rubber is black and has a moderate softness. Black wave - shaped rubber has stable quality, and the moderate softness ensures a tight fit with the lifting pin anchor, playing a good protective and buffering role.
Duck - bill Lifting Tool (Duck - bill Hook)：As a lifting tool, it is used in conjunction with lifting pin anchors to lift prefabricated components. Its surface is usually galvanized to improve its anti - rust ability, ensuring long - term use in a humid construction environment and the safety and reliability of lifting operations.
Alternative Products and Their Supporting Parts：Threaded steel sleeves and universal lifting rings can be used as an alternative to the combination of wave - shaped rubber, lifting pin anchors, and duck - bill lifting tools. Threaded steel sleeves are consumables, and there are also supporting products such as longan - shaped parts and magnetic seats. Component manufacturers will choose between lifting pin anchors and threaded steel sleeves as embedded parts according to their own production processes, cost control, and other factors.
V. Precautions for Application
Use in Strict Compliance with Regulations：It is imperative to strictly select lifting pin anchors according to the specifications designed in the drawings. Different specifications of lifting pin anchors have different load - bearing capacities. If small - specification lifting pin anchors are used to lift overweight components, it is highly likely to trigger serious safety accidents such as falling and breaking, posing a threat to the lives of construction workers and the quality of the project.
Requirements for Pull - out Tests：When the requirements for the use of lifting pin anchors are not clearly specified in the design drawings, a pull - out test should be conducted. The pull - out test simulates the actual lifting force situation to detect the connection strength between the lifting pin anchor and the component and determine its load - bearing capacity. In actual use, it is advisable to select lifting pin anchors with specifications exceeding the test data to provide more ample safety guarantees for construction.
